Page 1 of 1 ACTION NO. ITEM NO. E-1 AT A REGULAR MEETING OF THE BOARD OF SUPERVISORS OF ROANOKE COUNTY, VIRGINIA HELD AT THE ROANOKE COUNTY ADMINISTRATION CENTER MEETING DATE: March 22, 2016 AGENDA ITEM: Resolution setting the allocation percentage for personal property tax relief in Roanoke County for the 2016 tax year SUBMITTED BY: Laurie Gearheart Assistant Director of Finance APPROVED BY: Thomas C. Gates County Administrator COUNTY ADMINISTRATOR'S COMMENTS: BACKGROUND: The Personal Property Tax Relief Act (PPTRA or the Act) of 1998 established a State-wide program to provide relief to owners of personal use motor vehicles. The Act provides State funds to localities to reduce local government taxation of personal property. In 2004 and 2005, additional legislation was passed to amend the original Act. This legislation capped PPTRA at $950 million for all Virginia localities for tax years 2006 and beyond. PPTRA funds are allocated to individual localities based on each government's pro rata share of tax year 2004 payments from the Commonwealth. The County's share of the $950 million is $12,229,857. At the December 20, 2005 Board meeting, the Board of Supervisors adopted ordinance 122005-10 which amended the Roanoke County Code by adding a new Section 21-225 to provide for the implementation of the 2004-2005 changes to the Personal Property Tax Relief Act (PPTRA) of 1998. The amount the County receives from the State has stayed constant since 2006. However, the personal property tax base has continued to grow, which has caused less of the personal property tax bill to be offset by PPTRA Funds. Attached is a schedule showing the reimbursement rates since 2005. Page 1 of 2 SUMMARY OF INFORMATION: Since 2006, The County has used The PPTRA Allocation Model developed by the State to calculate the effective reimbursement rate. This model uses historical trends and a five (5) -year rolling average to calculate the effective reimbursement rate. This same methodology for calculating the rate is used by many of our neighboring localities. For 2016, County staff has once again computed the effective reimbursement rate based upon the PPTRA allocation model. The rate for the County is 58.07% and the Town of Vinton is 61.71%. The Board is required by the State to annually adopt a resolution setting the percentage reduction in personal property for that year. The attached resolution establishes the percentage reduction at 58.07% for the 2016 tax year. FISCAL IMPACT: The percentage reduction is calculated to distribute the $12,229,857 block grant allocation from the State in the manner described above. There will be some timing delays in the receipt of the State funds since they are received in the following fiscal year (2016-2017). However, we are allowed to accrue these funds back to the 2015-2016 year for accounting purposes, therefore our budget will be balanced. STAFF RECOMMENDATION: Staff reviewed this calculation and recommends adopting the attached resolution, which establishes the percentage reduction for personal property tax relief at 58.07% for Roanoke County for the 2016 tax year. Page 2 of 2 AT A REGULAR MEETING OF THE BOARD OF SUPERVISORS OF ROANOKE COUNTY, VIRGINIA, HELD AT THE ROANOKE COUNTY ADMINISTRATION CENTER ON TUESDAY, MARCH 22, 2016 RESOLUTION SETTING THE ALLOCATION PERCENTAGE FOR PERSONAL PROPERTY TAX RELIEF IN ROANOKE COUNTY FOR THE 2016 TAX YEAR WHEREAS, in accordance with the requirements set forth in Section 58.1-3524 (C) (2) and Section 58.1-3912 (E) of the Code of Virginia, as amended by Chapter 1 of the Acts of Assembly and as set forth in item 503.E (Personal Property Tax Relief Program or "PPTRA") of Chapter 951 of the 2005 Acts of Assembly and qualifying vehicle with a taxable situs within the County commencing January 1, 2016, shall receive personal property tax relief; and WHEREAS, this Resolution is adopted pursuant to Ordinance 122005-10 adopted by the Board of Supervisors on December 20, 2005. NOW THEREFORE, BE IT RESOLVED, BY THE BOARD OF SUPERVISORS OF ROANOKE COUNTY, VIRGINIA, as follows: 1. That tax relief shall be allocated so as to eliminate personal property taxation for qualifying personal use vehicles valued at $1,000 or less. 2. That qualifying personal use vehicles valued at $1,001-$20,000 will be eligible for 58.07% tax relief. 3. That qualifying personal use vehicles valued at $20,001 or more shall only receive 58.07% tax relief on the first $20,000 of value; and 4. That all other vehicles which do not meet the definition of qualifying (for example, including but not limited to, business use vehicles, farm use vehicles, motor homes, etc.) will not be eligible for any form of tax relief under this program. Page 1 of 2 5. That the percentages applied to the categories of qualifying personal use vehicles are estimated fully to use all available PPTRA funds allocated to Roanoke County by the Commonwealth of Virginia. 6. That this Resolution shall be effective from and after the date of its adoption.

ITEM NO. E-2 AT A REGULAR MEETING OF THE BOARD OF SUPERVISORS OF ROANOKE COUNTY, VIRGINIA HELD AT THE ROANOKE COUNTY ADMINISTRATION CENTER MEETING DATE: March 22, 2016 AGENDA ITEM: Resolution adopting revisions to the Stormwater Management Design Manual SUBMITTED BY: Arnold Covey Director of Development Services APPROVED BY: Thomas C. Gates County Administrator COUNTY ADMINISTRATOR'S COMMENTS: SUMMARY OF INFORMATION: Roanoke County currently has a Stormwater Management Design Manual that supplements the adopted new stormwater management ordinance. The purpose of the manual is to assist engineers and developers to prepare development plans that meet County/State requirements and assist the County in implementing its post -construction responsibilities (periodic inspection). Generally all chapters have: • Updated references to current manuals. • Spelling/grammar corrections. • Acronyms and units revised to correct nomenclature. Many chapters have numerous minor changes in technical or procedural requirements in response to our experience over the past year running the County's Virginia Stormwater Management Program (VSMP). Page 1 of 3 Following are some of the more significant proposed changes: • Require additional information for development with wetlands • Submittal of stormwater master plan for phased plans in a common plan development • Additional information for stormwater plans to improve review efficiency and recordkeeping • Add section on residential lot grading and drainage • Expand the requirements for as -built (record) drawings County staff has reviewed these changes with the Roanoke Regional Home Builders Association (RRHBA) and with the Board of Supervisors at a work session on August 25, 2015. Following September 22, 2015 Board meeting, the staff met several times with the Roanoke Regional Home Builders Association (RRHBA) and together resolved all outstanding issues. Since the January 26, 2016 Board work session, it has been brought to staff attention there are some minor clarifications that need to be addressed. The following are revisions that have been made to the Stormwater Design Manual. • Section 1.7.1 was revised to three (3) feet instead of two (2) feet to reflect the current change to the State's Building Code when a building permit is required fora retaining walls. • Section 5.2.7E was revised to clarify that yard swales must have a grass liner due to a missing word in the previous version of the manual. • Section 7.2.6 B was revised to provide clarity that the maximum pipe velocity is based on the ten (10) -year storm. • Section 7.2.9 B was revised to clarify that two (2) feet of cover is required for pipes. Pipes not meeting the cover requirements may be approved by staff based upon site conditions. • Section 15.1.4 was revised to provide additional clarification for CAD drawings layer requirements that are provided for County's GIS. • Section 2.4 was revised to provide optional delineation of disturbance limits in the field. • Section 4.4.3 was revised to allow multiple design methods for BMP design. • Section 4.7 was revised to provide clarification to the requirements. • Section 5.2.1 and 5.2.2 were revised to provide clarification and to remove duplication. • Section 5.2.9 was revised to provide clarification. • Section 7.2.9B was revised to remove duplication • Section 12.2.2 was revised to simplify requirements language. • Section 15.1.3 was revised to simplify requirement language. The attached resolution includes all updates and corrections as discussed. Page 2 of 3 FISCAL IMPACT: None ALTERNATIVES: 1.

TABLE OF CONTENTS q444X/1/16- Chapter 1 - Introduction 1.1 Manual Purpose As land is developed and woodlands and pastures are converted to more intensive commercial and residential uses, the increase in impervious surfaces (pavements-a*d, buildings etc.) and managed turf, cause adverse effects including: Formatted: Highlight • Increased flooding • Increased erosion and deposition of sediment in streams • Less base flow in streams due to less groundwater recharge • Increased runoff of pollutants (nutrients, sediment, bacteria, oil) • Decreased stream biodiversity (e.g.,aquatic insects and fish) • Loss of recreational uses such as swimming and fishing The County of Roanoke stormwater management goals are to minimize these adverse effects of land development by implementing effective stormwater management Best Management Practices (BMPs) as required by the County Code for new and redevelopment, and over Formatted: Highlight time, by providing BMP measures to mitigate the adverse effects of past land development activities. The County of Roanoke Stormwater Management Design Manual, hereafter called the Design Manual, contains local requirements that supplement local ordinances, state regulations and guidance, and federal regulations. In general. I4ee4aft4irection and guidance from these sources is not repeated in this Design Manual. Refer to the listing of Reference Sources at the end of this chapter. 1.2 Water Programs Regulatory Background The County of Roanoke implements, and is regulated by, several water programs as briefly described below. Land Disturbing Activities are regulated under the erosion and sediment control, stormwater management, and floodplain management programs. Existing Development is regulated by the illicit discharge detection and elimination program and, if the property contains a permanent BMP, by the stormwater management program. The County of Roanoke itself is regulated by the MS4 Permit program. While the MS4 permit only directly regulates the County, it may indirectly impact anyone living in, owning property, or developing in the County of Roanoke through the impact of County actions that are required by its permit. COUNTY OF ROANOKE 7444x/1/16 1-1 INTRODUCTION 1.2.1 Erosion and Sediment Control Program The County is the local Erosion and Sediment Control (E&SC) authority. E&SC requirements are contained in the County of Roanoke Erosion and Sediment Control Ordinance and Virginia Erosion and Sediment Control Regulations. The County administers the program under the oversight of the Virginia Department of Environmental Quality (DEQ). 1.2.2 Stormwater Management Program The County is the local Virginia Stormwater Management Program (VSMP) authority. VSMP requirements are contained in the County of Roanoke Stormwater Management Ordinance and Virginia Stormwater Management Regulations. The County administers the program with oversight of the DEQ. The proper understanding of the meaning of "common plan of development or sale" is critical to understanding the applicability of stormwater management requirements for land disturbing activities. The County's policy concerning common plan of development or sale is contained in Appendix IA. 1.2.3 Floodplain Management Program The County regulates development in the floodplain through its Zoning Ordinance. This Program was developed and is administered to comply with Federal Emergency Management Agency requirements. 1.2.4 Illicit Discharge Detection and Elimination Program Except for specific limited exceptions, only uncontaminated stormwater may be discharged into stormwater systems. The County operates an Illicit Discharge Detection and Elimination Program in accordance with the County of Roanoke Illicit Discharge Ordinance, as required by its MS4 Permit. The DEQ provides oversight of this program. 1.2.5 Municipal Separate Storm Sewer System (MS4) Permit The County of Roanoke is regulated under a General Permit for Small Municipal Separate Storm Sewer Systems issued by the DEQ. MS4 permits generally impact urban areas and they require the locality to implement specific Minimum Control Measures (MCM) to protect local water quality. These MCM's generally fall into six 6) categories: 1. Public Education and Outreach on Stormwater Impacts 2. Public Involvement and Participation 3. Illicit Discharge Detection and Elimination 4. Construction Site Stormwater Runoff Control 5. Post Construction Stormwater Management COUNTY OF ROANOKE 7444x/1/16 1-2 INTRODUCTION 6. Pollution Prevention and Good Housekeeping for Municipal Operations The MS4 Permit also requires that the locality address water impairments that are identified by a Total Maximum Daily Load (TMDL) Study where the locality has been given a Waste Load Allocation (WLA). The County of Roanoke has WLA's for a number of its streams for impairments caused by sediment, bacteria, and PCB's. See the Roanoke County website, Department of Community Development, Stormwater Management page for more information concerning the MS4 Permit and TMDL's. 1.3 Contents of the Manual —The Design Manual is divided into 15 chapters.

In the event that this policy conflicts with any guidance issued by DEQ, DEQ guidance will govern. All land -disturbing activities, except those specifically exempted in Section 23-1.3 of the Roanoke County Stormwater Management Ordinance, require approval from Roanoke County as the local VSMP authority and coverage under the state General Permit for Discharges of Stormwater Ffem from Construction Activities prior to commencing land -disturbing activities. Several exemptions apply to land -disturbing activities that disturb less than one acre of land and that are not part of a larger common plan of development or sale. In order to properly apply these exemptions, it is necessary to understand what is meant by "common plan of development or sale." It is critical for developers and land -owners to understand that the permitting exemption can be lost by disturbing more area on a project than planned (exceeding 1 acre land - disturbance) or by taking actions that demonstrate that a small project (less than 1 acre land -disturbance) is part of a larger common plan of development or sale. Actions that increase land disturbance or that create a larger common plan of development after plan approval and during construction will necessitate securing a VSMP permit, may result in possible enforcement and penalty actions, and may result in additional costs and delays due to the need to redesign the site and construct or modify BMPs. Land disturbing activities that are exempt from the requirements of the Stormwater Management Ordinance may not be exempt from the Erosion and Sediment Control stormwater management requirements. Erosion and Sediment Control regulations could still require stormwater management to address Minimum Standard 19. 1A.2 State Definition and Guidance 9VAC25-870-10 defines common plan of development or sale in the following manner: "Common plan of development or sale" means a contiguous area where separate and distinct construction activities may be taking place at different times on different schedules. For the purposes of the VSMP regulations, individual lots within existing residential, commercial, or industrial site plans and subdivision plans that were platted prior to July 1, 2004 may be considered separate land -disturbing activities. COUNTY OF ROANOKE 7444-x/1/16 INTRODUCTION IA -2 1A.3 Discussion and Application 1A.3.1 USEPA guidance(-http://cfpub.epa.gov/npdes/fags.cfm?program id=6 ) A "larger common plan of development or sale" is a contiguous area where multiple separate and distinct construction activities may be taking place at different times on different schedules under one plan. For example, if a developer buys a 20 -acre lot and builds roads, installs pipes, and runs electricity with the intention of constructing homes or other structures sometime in the future, this would be considered a larger common plan of development or sale. If the land is parceled off or sold, and construction occurs on plots that are less than one acre by separate, independent builders, this activity still would be subject to stormwater permitting requirements if the smaller plots were included on the original site plan. The larger common plan of development or sale also applies to other types of land development such as industrial parks or well fields. A permit is required if one (1) or more acres of land will be disturbed, regardless of the size of any of the individually -owned or developed sites. 1A.3.2 The creation of a common plan of development or sale A common plan of development or sale comes into being when there is documentation showing plans or intent to disturb earth regardless of how many phases or how long it will take. Common documents that create a common plan of development include: (a) any announcement or documentation (marketing plans, sign, sales pitch, notice, etc_); (b) any physical demarcation (boundary signs, lot stakes) indicating construction may occur on a specific plot; (c) subdivision plats; or, (d) construction drawings. 1A.3.3 The completion of a common plan of development or sale Once a common plan of development or sale has been created, it remains in force until the contemplated development is substantially completed (less than one (1) acre remaining to be developed). There may be a time when a new developer will want to perform a land disturbing activity on an undeveloped parcel (that was created on or after July 1, 2004), and wants to know if a common plan of development or sale is still valid. In order for the new activity to not be a part of the original common plan of development or sale, it must meet 2 tests. Test 1: Was the original plan, including modifications, ever substantially completed with less than one (1) acre of the original common plan of development or sale remaining (e.g., less than one (1) acre remains to build out)? Test 2: Has there been a clearly identifiable period of time where there is no on- going construction, including meeting criteria for final stabilization? (Roanoke County, by this policy, sets the clearly identifiable period of time at one (1) year.) If the project meets the two tests, then it may be evaluated for permitting purposes on its individual merits. If it does not meet either of the two tests, then it remains part of the original common plan of development or sale, and it requires permit coverage. COUNTY OF ROANOKE 7444--x/1/16 IA -3 INTRODUCTION 1A.3.4 Additional development on an individual parcel after the intended construction is completed When the intended construction on a parcel that is part of a larger common plan of development or sale is completed, any subsequent development or redevelopment of that parcel is considered a new plan of development. 1A.3.5 Effect of adding property to an existing project There are 2 cases where adding land to a project could have permitting impacts. Case 1: A common plan of development or sale has already been created and development of the common plan of development or sale is ongoing. The developer purchases additional property to incorporate into the development. The additional property would become part of the common plan of development or sale. Case 2: A developer subdivides a parcel to create a residential lot. The development of the lot will disturb less than 1 acre. No stormwater permit is required. Prior to a clearly identifiable period of time (1 year) where there is no on-going construction on the first lot, the developer creates a second lot from the original parcel (or markets additional homes prior to creating lots). The development of the second lot would disturb less than 1 acre; however, the development of the first lot and the second lot together would cumulatively disturb 1 acre or more. A larger common plan of development or sale has been created. A permit is required to cover the entire common plan of development or sale (both the construction on Lot 1 as well as Lot 2 and any subsequent lots). Construction on Lot 1 would need to halt until permitting is completed. Stormwater management requirements would need to be met for the entire common plan of development or sale. 1A.3.6 Timing for construction and ownership of BMPs for a common plan of development or sale The technical criteria for stormwater management must be applied to the entire common plan of development or sale. In some cases, portions of a common plan of development or sale may have BMPs with a higher efficiency of pollutant removal or stormwater volume or rate control than other portions of the common plan of development or sale. However, no portion of the common plan of development or sale shall be considered by the County to be completed or be allowed to be occupied until BMPs are completed and functioning that provide stormwater management for that portion of the common plan of development or sale adequate to meet minimum standards (e.g., the construction of BMPs cannot be deferred to a later phase, if the portion of the common plan of development or sale that is currently under construction does not have adequate BMPs to meet the stormwater management technical criteria). COUNTY OF ROANOKE 7444-x/1/16 IA -4 INTRODUCTION BMPs that provide stormwater management for one individual parcel may be on the individual parcel and may be owned and maintained by the property owner of the individual parcel. At the developer's option, BMPs that provide stormwater management for one individual parcel may be made a property association's responsibility as described in the next paragraph. BMPs that provide stormwater management for more than one parcel must be owned and maintained by a property association, consisting of all property owners that are benefiting from the BMP. 1A.3.7 De minimus land disturbance Neither federal nor state definitions or guidance address de minimus land disturbance on a lot within a larger common plan of development or sale. It is obvious that at some point, minor land disturbing activities should not be regulated, within a larger common plan of development or sale; example — disturbance of 20 square feet, on a lot, to erect a temporary sign. For the purpose of implementing the VSMP, Roanoke County considers land disturbance of less than 2,500 square feet to be de minimus and will not fall under the VSMP regulations. If any additional land disturbance occurs on a lot, within a larger common plan of development or sale, within one (1) year of completing the original disturbance, the land disturbance area will be summed. If the summed land disturbance is greater than 2,500 square feet, then the total land disturbed must comply with the VSMP regulations. 1AA Examples 1A.4.1. Example 1 A residential subdivision was started after July 1, 2004. Only 60 of the 100 lots have been developed, with the remaining 40 lots constituting 1 acre or more. No development has occurred since around 2010. A developer intends to develop a vacant'/2 acre lot. This situation applies to a vacant lot in accordance with Section M.3.3. The residential subdivision is a common plan of development or sale. While a clearly identifiable period of time of no construction has passed (Test #2), the project was never substantially completed (Test 91). Therefore, the developer requires a VSMP permit. 1A.4.2 Example 2 A residential subdivision was constructed around 2010. About 80 of the 100 lots have been developed, with the remaining 20 lots constituting 1 acre or more. The owner of one of the constructed homes intends to construct an addition to his home that will disturb 3,000 square feet. This situation applies to an individual parcel after intended construction has been completed in accordance with Section 1.3.4. The residential subdivision is a common plan of development or sale. However, the intended construction has been completed on this lot. Therefore, the addition is treated as a new development project. Since it disturbs less than I acre, no VSMP permit is required. COUNTY OF ROANOKE 7444-x/1/16 1A-5 INTRODUCTION 1A.4.3 Example 3 A regional shopping center was built in the 1990s. It is currently marketing plans to develop several additional buildings in its parking lot. It anticipates that the buildings will be constructed one at a time. The anticipated disturbed area for the construction of each building is less than 1 acre, but the anticipated disturbed area for the construction of all of the additional buildings is over an acre. The common plan of development or sale occurred prior to July 1, 2004, and the original plan is completed. Each of the proposed buildings will disturb under I acre; however, since the 3 buildings are being marketed together, a new common plan of development or sale has been created and the construction of all three buildings must be considered as a single land -disturbing activity. A VSMP permit is required. 1A.4.4 Example 4 A regional shopping center was built in the 1990's. The owner intends to construct a building expansion that will disturb 0.8 acres. Just over a year after completion of the expansion, the owner of the regional shopping center decides to construct another building in its parking lot. The building construction will disturb 0.7 acres. The common plan of development or sale occurred prior to July 1, 2004, and the original plan is completed. The developer intends to construct a building expansion as a stand- alone project. The project will disturb less than I acre; therefore, no VSMP permit is required. After a distinct time period (I year) has passed with no construction activity, the developer decides to construct another building in its parking lot. Since a distinct time period (I year) has passed since the completion of the building addition, and since the new building is not part of the building expansion plan, and since less than I acre is disturbed, no common plan of development or sale is created and no VSMP permit is required. Note If the building expansion and additional building in the parking lot were part of an overall renovation plan that was intended to be constructed in phases, then a common plan of development or sale would have been created and a VSMP permit would have been required. 1A.4.5 Example 5 A congregation intends to build a new church in phases. Phase 1 is for a multipurpose sanctuary and parking and the construction will disturb 2 acres. Phase 2 is for a classroom expansion and its construction will disturb 0.5 acres. The phased church construction is a common plan of development or sale. A VSMP permit will be required for Phase I and Phase 2. COUNTY OF ROANOKE 7444--x/1/16 IA -6 INTRODUCTION 1A.4.6 Example 6 A congregation intends to build a new wing for education use and expand the parking lot. No construction has been built for over a year. The construction will disturb 0.8 acres. The proposed project is separate from the original church construction; therefore, it is not part of a larger common plan of development or sale. Since disturbed area is less than I acre, no VSMP permit is required. 1A.4.7 Example 7 A developer has a plan approved that indicates that 0.9 acres will be disturbed. During construction, the developer actually disturbs 1.2 acres. The developer's plan indicates that less than I acre will be disturbed. Therefore, no VSMP permit was required. However, the developer actually disturbed over 1 acre. Therefore, the County issues a "Stop Work" order until a VSMP permit can be issued. A stormwater management plan meeting the stormwater management regulation technical requirements must be prepared and submitted, along with an executed and recorded maintenance agreement, revised performance security, and additional fees. The developer must ensure that an adequate SWPPP is prepared and available at the site. No further land -disturbance activities may occur until these items are completed and a VSMP permit is issued. The County may undertake other enforcement actions and penalties, depending on the circumstances. 1A.4.8 Example 8 An existing fast food restaurant is part of a partially developed commercial area. It plans a renovation that includes some parking lot changes and a small expansion to its seating area. The construction disturbed area is 0.7 acres. The commercial area is part of an active common plan of development or sale; however, the intended construction (fastfood restaurant) on this parcel has been completed. In accordance with Section M.3.4, the renovation is a separate land -disturbing activity. Since less than I acre is disturbed, no VSMP permit is required. 1A.4.9 Example 9 A developer intends to construct a subdivision in two phases. He intends to develop Phase 1 first, followed by Phase 2. Since the subdivision is a common plan of development or sale, the two phases are treated as a single land disturbance activity and the determination of whether or not adequate stormwater management is being provided is analyzed for the subdivision as a whole. Stormwater management for the subdivision will be accomplished by a combination of BMPs on individual lots, to serve the individual lots; and BMPs intended to serve multiple lots. Due to the characteristics of COUNTY OF ROANOKE 7444-x/1/16 IA -7 INTRODUCTION the site and the layout of the design, the overall plan indicates that the proposed BMPs for Phase 1 are not adequate to meet the pollutant removal requirements, but that with the construction of Phase 2, the overall effectiveness of the BMPs will be increased so they are adequate to meet the pollutant removal requirements for both Phase 1 and Phase 2 upon completion of Phase 2. The proposed plan is unacceptable in accordance with Section 1.3.6. Even though it is expected that portions of the common plan of development or sale will have more effective BMPs than other portions of the common plan of development or sale, and even though the common plan of development or sale is evaluated as a single land -disturbance activity; It is not acceptable to construct a portion of the common plan of development or sale without concurrent construction of adequate BMPs such that the technical requirements of the stormwater management regulations are met as each portion of the common plan of development or sale is completed. 1A.4.10 Example 10 A land -owner owns a parcel with existing public road frontage. The current zoning and subdivision requirements would allow for the parcel to be subdivided into 8 lots without the need for any additional public infrastructure. The property owner divides the parcel to create one 1/4 acre lot and constructs a single family house on it. Several years after completion of the single family house, the property owner divides the parcel again to create another 1/4 acre lot and constructs another single family house. Each project is separated by adequate time that they are independent projects and no VSMP permit is required. 1A.4.11 Example 11 A land -owner owns a 10 acre parcel with existing public road frontage. The current zoning and subdivision requirements would allow for the parcel to be subdivided into 8 lots without the need for any additional public infrastructure. The property owner divides the parcel to create one 1/4 acre lot and sells the individual lot to a developer to construct a single family house on it. After the property sale, the landowner posts a sign on his property stating that "land is available for development and that the owner will subdivide". The owner has created a larger common plan of development or sale by marketing development on his parcel. The developer may continue with his project to construct a single family house, since the property was sold to him prior to the creation of the larger common plan of development or sale. However, any further construction on the land- owner's parcel will require a VSMP permit.

Plans should be submitted in compliance with the Digital Plan Submission Guide policy. (http://www.roanokecountyva.gov/index.aspx?NID=317) These plans will be distributed to the appropriate departments and divisions for review and approval. When required, the applicant is also responsible for submittals to the Virginia Department of Transportation, Virginia Department of Environmental Quality, Western Virginia Water Authority, Town of Vinton, and other applicable regulatory agencies for their review and approval. When applicable, all of these entities must approve the site development plan prior to the issuance of any permits for all types of developments as required by the Zoning Ordinance, Subdivision Ordinance, Erosion and Sediment Control Ordinance, and Stormwater Management Ordinance. In cases where jurisdictional waters exist on the proposed site, the applicant may need to obtain approvals and/or permits from any or all of the following agencies: the U.S. Army Corps of EngineersU( SACE), the Federal Emergency Management Agency, the Virginia Department of Environmental Quality (DEQ), and the Virginia Marine Resource Commission (VMRC). Itis the responsibility of the applicant to obtain all necessary permits from USACE, DEO, VRMC, etc and provide Roanoke County with a copy of the required permit(s). Approval of plans by Roanoke County does not alleviate the applicant's liability of obtaining the required permit(s). 2.1 Overview of the Review and Approval Process No application for land development, land use conversion, or land disturbance can be approved, and no permits issued, without all of the elements required for a VSMP permit, as more fully described in the County Stormwater Management Ordinance and 9VAC25-870- 55. These elements generally include a permit application, erosion and sediment control plan, stormwater management plan, stormwater maintenance agreement, performance bond, fees, and executed development agreements. An agreement in lieu of a stormwater management plan may be accepted for a detached single family residence that is not part of a common plan of development. —The submittal, review, and approval of site development plans, including stormwater management plans will follow the Roanoke County Land Development Procedures. This document is available from the County of Roanoke Department of Community Development website (http://www.roanokeco=va.gov/index.aspx?NID-317).

COUNTY OF ROANOKE STORMWATER MANAGEMENT PLAN 7/A444x/1/16 REVIEW AND APPROVAL 2-5 EASEMENTS CHAPTER 3 Chapter 3 - Easements 3.1 General This manual addresses three types of easements: • Private drainage easements; • Public drainage easements; and • Access Easements Easements may be required as a part of a subdivision plat or site plan review. The purpose of this section is to provide policy, procedures, and guidelines for establishing easements for storm drainage and BMPs. Easements may grant certain rights and privileges to the County or other public entity such as VDOT for public easements, or to specific landowners and/or the County in the case of private easements. Proposed easements will be shown conceptually on preliminary site plans. The easements will be in final form on the submitted stormwater management plan and will be consistent with the design on final plats and site plans. Easements shall be dimensioned to allow them to be located in the field by providing dimensional ties to property corners, or centerline bearings and distances. Where easements are aligned with property lines, offset dimensions will be provided. Verification of easement locations will be required as a part of the as -built drawing requirements. If drainage or BMPs are found to have been constructed outside of the easement; then, the permittee will be responsible for vacating the original easement and recording a new easement, in the proper location, at the permittee's expense. Easements should not split property lines. Where an open channel or storm drain system runs parallel to a property line, it should be offset from the property line an adequate amount so that the easement is totally contained on the property that contains the open channel or storm drain and not be split onto the adjacent property. This provision allows construction of fences at the property line. All easements, shall connect to public access points. Easements shall be wide enough, and shall be located to allow convenient access for inspection and repairs, regardless of the minimum widths given herein. 3.2 Drainage Easements Public drainage easements giving the County or a public entity such as VDOT the right to discharge stormwater runoff onto private property is required for all public storm drainage systems and BMPs that are located on private property. This includes open channels, culverts, inlets, storm drains, stormwater management basins, and other best management practices that are owned, operated, and maintained by the County or other public entity such as VDOT. COUNTY OF ROANOKE EASEMENTS ^//14 x/1/16 3-1 EASEMENTS CHAPTER 3 Public storm drainage systems are used to convey stormwater drainage from public property, public right-of-way, or another public storm drainage system through private property. Once the stormwater is discharged into a perennial or intermittent stream, or is otherwise managed, a public drainage easement is not required. Public BMPs are used to provide appropriate stormwater management for stormwater runoff generated by land development on public property. Examples of situations where a public drainage easement is required include: • Concentrated stormwater runoff from a County or County School Board owned site discharging to private property, including any open channels leaving the property or any storm drains leaving the property. • Concentrated stormwater runoff from public streets and open channels or storm drains from the public street right-of-way which passes onto any private property. Private drainage easements giving a private party the right to discharge concentrated stormwater runoff onto downstream private property is required whenever connection is made to a downstream private storm drainage system. No buildings, foundations, structures, fences or walls, not associated with the storm drainage system or BMP shall be located within a drainage easement. In addition, easements that contain open channels shall not be obstructed by fences or unmanaged vegetation. The closest edge of a storm drainage easement shall not be located within 10 feet of the rear wall of any individual single-family residential structure, except where the easement is required to access a BMP that is solely serving the single-family residence. Underground utility lines and structures shall be kept at least 5 -feet horizontal from drainage pipes, structures, and channels, except at utility crossings. Utility crossings at drainage easements shall be at as near 90-degress as possible. Where a storm drainage system terminates or starts short of a property line, adequate drainage easements shall be dedicated to allow for maintenance and future extension of the system through the property. 3.2.1 Culverts and Storm Drains The minimum width of drainage easements for culverts and storm drains shall be as follows: Pipe Size (width) Minimum Easement Width # Smaller than 36" 20 feet 36" — 42" 25 feet 48" — 60" 30 feet COUNTY OF ROANOKE EASEMENTS ^//14 x/1/16 3-2 EASEMENTS CHAPTER 3 66" — 78" 35 feet `Minimum width given above is for installations with depths of cover of 10 -feet orI Formatted: Font: Bold less (measured at the top of pipe). For each additional 5 -feet of cover over 10 -feet (rounded up), the minimum easement width shall be increased by 10 -feet. for pipes that are larger than given in the table above, and for installations that , - Formatted: Font: Bold result in minimum easement widths greater than 50 -feet due to installation depths, the minimum easement width shall be set by the County based on the width requirements to access the pipe in the future for repair. Drainage easements at the inlet and outlet of all culverts and storm drain inlets shall include the areas inundated by the headwater during the 100 -year storm. The easement shall extend a minimum of 10 feet from culvert inlets and outlets and storm drain inlets to allow for maintenance access. Where steep slopes and/or deep fills exist, additional easement area may be required to allow for proper access. Storm drain easements shall cross private driveways at perpendicular angles to the extent practical. 3.2.2 Open Channels The minimum width of the drainage easement required is dependent on the top width of the channel as indicated in Figure 3-1. The County may require wider easement width, if the open channel is located in rough terrain and additional width is required for access for inspection or repair.

This includes stormwater management basins, filter strips, bioretention trenches, underground detention areas, and all other BMP's. All structures, pond areas, embankments, inlet and outlet channels, and access and working areas necessary to inspect, maintain, and repair the facilities shall be included in access easements. The 100 -year flooding area of all stormwater basins or other holding structures shall be contained within the access easement area. In addition, all BMPs shall contain a minimum 20 -foot working area around all stormwater management basins and a minimum 10 -foot working area around all other BMPs and an access easement connecting to a public road. Depending on the size and location of the stormwater management facility, more than one vehicle accessible access easement connecting to a public road may be required. All stormwater structures and BMPs shall be accessible by vehicle. Areas within an access easement that are intended to be vehicle accessible shall have a maximum slope of 10 percent for unpaved surfaces and 18 percent for paved surfaces. The vehicle access shall be a minimum of 12 feet in width. The minimum width for an access easement shall be 20 feet. All access easements shall connect to a public road or right of way; unless a suitable blanket access easement is provided. 3.4 Maintenance of Easements COUNTY OF ROANOKE EASEMENTS 74/14-x/1/16 3-4 EASEMENTS CHAPTER 3 Ownership of land within easements shall remain with the property owner. The property owner shall have the responsibility of maintaining the easement areas free of any obstructions or use that would interfere with the rights or privileges granted by the property owner. The property owner shall not alter the existing ground elevations or in any way redirect or obstruct stormwater flow. Any alterations to easements resulting in obstruction or redirection of flow will be returned to existing elevations immediately at the cost of the property owner.

The primary design references are: • VDOT Drainage Manual • VA SWM Handbook • BMP Clearinghouse 4.2 Design Frequencies 4.2.1 General Design frequencies shall be selected consistent with good engineering practice and economics. The design frequency requirements given in this Design Manual are minimum, specific conditions may dictate that less frequent design frequency should be used. 4.2.2 Storm Drainage Systems Storm drainage systems consist of manmade open channels, culverts, and storm drains.

Where justified by the consequences of failure, the minimum design frequency shall be increased. 4.2.3 Stormwater Management Facilities Designs shall be in accordance with the VA SWM Handbook and BMP Clearinghouse. 4.3 Time of Concentration (t�) and Travel Time (Tt) 4.3.1 General Time of Concentration (Q is the length of time required for a drop of water to travel from the most hydraulically distant point in the watershed, or subwatershed to the point of analysis. Travel Time (T) is the length of time required for that same drop of water to travel from the study point at the bottom of the sub - watershed to the study point at the bottom of the whole watershed. The travel time is descriptive of the sub -watershed by providing its location relative to the study point of the entire watershed. Therefore Time of Concentration is the summation of Travel Time values for the various consecutive flow segments. Travel Time and Time of Concentration generally consist of four flow types - overland flow, shallow concentrated flow, channelized flow, and pipe systems. Calculations shall be reviewed for reasonableness and the results shall be revised if needed to provide a reasonable velocity and flow time that will best represent the study area. When designing a drainage system, the flow path is not necessarily the same before and after land disturbing activities have been completed. Therefore, the travel time path shall be reflective of the actual conditions both before and after the land disturbing activities. In some cases, runoff from a portion of the drainage area that is highly impervious may result in a greater peak discharge than would occur if the entire area were considered. In this case, adjustments can be made to the drainage area by disregarding those areas where flow time is too slow to add to the peak discharge. COUNTY OF ROANOKE 7444X/1/16 4-2 STORMWATER HYDROLOGY STORMWATER HYDROLOGY CHAPTER 4 To prevent small drainage areas from skewing the time of concentration calculation results, when establishing sub drainage areas for analysis, the largest sub drainage area shall be no greater than 5 times the area of the smallest sub drainage area. Time of concentration maps shall include segment lengths, elevations at beginning and end of segment, slopes, and flow types. 4.3.2 Overland Flow Overland flow is flow that occurs at the upper end of a watershed, where flow is not concentrated and there are no channels. The length of overland flow shall be reflective of actual conditions and shall normally be po greater than 150 feet-------- Formatted: Underline Where the overland flow does not contain any slopes exceeding 5% AND if the soils are not designated as highly erodible, a maximum length of overland flow of 200 feet may be used. Highly erodible soils are designated as United States Department of Agriculture Natural Resources Conservation Service land capability classification (LCC) classes IIIe, IVe, VI, VII, or VIII or having an erodibility index greater than or equal to 8.—Overland flow shall be calculated using the Seelye chart contained in the Appendix 4A for the Rational Method or TR -55 for the SCS Method. Roughness coefficients (Manning's n) for sheet flow can be found in the TR -55 Manual. 4.3.3 Shallow Concentrated Flow Shallow concentrated flow is the flow that occurs when minor rivulets form just downstream from the overland flow. The maximum allowable length for shallow concentrated flow shall be 1000 feet. Shallow concentrated flow shall be calculated using the Overland Flow Velocity - - Formatted: indent: Left: r', First line: 0" Chart from HEC -19 or by using the nomograph entitled "Time of Concentration of Small Drainage Basins," developed by P.Z.

Results from the Kirpich nomograph shall be multiplied by 0.2 for paved channels. 4.3.4 Channelized Flow Channelized flow occurs where stormwater flow converges in gullies, ditches, and natural or man-made water conveyances, including storm drain pipes and culverts. Channelized flow shall be calculated by use of the nomograph entitled "Time of Concentration of Small Drainage Basins," developed by P.Z. Kirpich.

Use full -flow pipe velocities, unless it may be demonstrated that the pipe will operate at partial full conditions. If it can be shown that the pipe will operate at partial full conditions, then the partial full pipe velocity may be used. Design of flow through culverts is presented in Chapter 6. Design of flow in storm drain systems is presented in Chapter 7. 4.4 Selection of Methodologies 4.4.1 General There are a variety of widely used hydrologic methodologies. Each has its strengths and weaknesses. In the interest of standardizing hydrologic calculations, the following methodologies will be used for all projects, unless the County agrees that good engineering practice dictates the use of another method. 4.4.2 Peak Discharge Methods for Design of Storm Drainage Systems The fAiena4-Rational +netl}ed-Method may be used to design storm drainage conveyance systems for drainage areas up to 200 acres. Minimum time of concentration when using the Rational Method is 5 minutes. The SCS method may be used for drainage areas up to 10 square miles. For drainage areas greater than 10 square miles, calculations shall be performed using at least two separate methods as described in the VDOT Drainage Manual (SCS method, regression equations, and/or stream gage data). The design peak flow shall be selected based on a professional evaluation of the results of the various methods. 4.4.3 Hydrograph Methods for Design of Stormwater Management Facilities The modified rational method may be used to design stormwater management facilities where drainage areas are less than 20 acres and times of concentration are less than 20 minutes. Minimum time of concentration when using the Rational Method is 5 minutes. Please be aware that DEQ's VRRMworksheet does not COUNTY OF ROANOKE 7444X/1/16 4-4 STORMWATER HYDROLOGY STORMWATER HYDROLOGY CHAPTER 4 support the use of the Rational Method when designing BMPs; therefore Roanoke County recommends using the SCS Method. The SCS method may be used in all cases. The SCS method must be used where drainage areas are 20 acres or greater, or where times of concentration are 20 minutes or longer. shall be used in the design of stormwater BMPs and ponds. Minimum time of concentration when using the SCS method is 6 minutes. 4.5 Methodologies Following is an abbreviated discussion of each method. Refer to the VDOT Drainage Manual and the VA SWM Handbook for a more complete discussion. 4.5.1 Rational Method �1. General Formatted: Font: Bold The Rational Method is expressed as: Q=CMA Where: Q = Peak flow rate of runoff, cubic feet per second (cfs) f = Saturation factor _ _ _ _ _ Commented [AG1]: C = Runoff coefficient representing a ratio of runoff to rainfall (dimensionless) I = Average rainfall intensity for a duration equal to the time of concentration for a selected return period, inches per hour (in/hr) A = Drainage area contributing to the design location, acres (ac) B. Saturation Factor ........ Formatted: Font: Bold The saturation factor (Cf) is an adjustment factor for modifying the runoff coefficient (C) for storms that are less frequent than a 10 -year recurrence interval. The product of Cf and C should not be greater than 1.0. Recurrence Interval (Years) Cf 2, 5, and 10 1.0 25 1.1 50 1.2 100 1.25 Where the product of Cf and C is greater than 1.0, use 1.0.

Funoff Coefficient _ _- Formatted: Font: Bold The runoff coefficient (C) is a variable of the Rational Method that requires significant judgment and understanding for proper selection. A range of C - values for a given land use is given in Appendix 4A. The coefficient must account for all the factors affecting the relation of peak flow to average rainfall intensity other than area adjustment. Some of these factors include land slope, condition of cover, and antecedent moisture condition. As the slope of the drainage basin increases, the selected C -value should also increase. The lower range of C -values should be used where the majority of the slopes are less than 2 -percent. The average range of C -values should be used where the majority of slopes are 2 to 5 -percent. The higher range of C - values should be used where the majority of the slopes are greater than 5 - percent. The higher range of C -values should be used in clayey and other less pervious soil areas.

General Formatted: Font: Bold The Modified Rational Method is a means to generate hydrographs for small drainage areas. The parameters for the calculation are the same as the Rational Method, except that a series of average rainfall intensities from different storms with the same frequency and different durations are computed. The hydrograph from the critical duration storm is used to design stormwater management facilities. The Modified Rational Method recognizes that the duration of a storm is often longer than the time of concentration. This longer duration storm, even though it produces a lower peak Q, can produce a larger volume of runoff than the storm duration equal to the actual time of concentration of the drainage area. In order to ensure the proper design of stormwater management facilities, the runoff for the critical storm duration shall be used. —B. Hydrograph Assumptions _ _ Formatted: Font: Bold The hydrograph generated by the Modified Rational Method is based on the following assumptions: • Time of Concentration (Q = Time to Peak (Tp) = Time to Recede (Tr) • The length of the critical duration storm (De) is from 0 minutes until the time of selected duration. • The rate of runoff is 0 at time 0 minutes. The rate of runoff increases linearly with time until the peak rate of runoff is reached at time Tp. • The peak rate of runoff is maintained from time Tp until the duration of the storm (De). The rate of runoff then decreases to 0 at time De plus Tr. • The peak rate of runoff is based on the average rainfall intensity (I) for the given storm duration. C._ Critical Duration Storni Formatted: Font: Bold The critical duration storm is the storm of a given frequency that has a duration that yields the greatest volume of storage in a stormwater management facility when the storm hydrograph is routed through the stormwater management facility. The critical duration storm may be COUNTY OF ROANOKE 7444X/1/16 4-7 STORMWATER HYDROLOGY STORMWATER HYDROLOGY CHAPTER 4 estimated for preliminary purposes; however, the actual critical duration storm must be determined by routing the various duration storm hydrographs through the stormwater management facility and demonstrating which storm duration gives the greatest volume of storage. 4.5.3 SCS Method A. General ---- - --------------------------------------- Formatted: Font: Bold The SCS Method may be used for computing peak flows and hydrographs for storms of selected return frequencies. This approach considers the time distribution of the rainfall, the initial rainfall losses to interception and depression storage and an infiltration rate that decreases during the course of a storm. The information required to use the SCS Method to determine the peak rate of runoff, or to develop a runoff hydrograph is: • 24-hour total rainfall, and rainfall distribution type. The 24 hour precipitation rate is based upon NOAA values at the Roanoke Airport. These values can be found on Roanoke County's website or NOAA's website. • Time of Concentration (Q in minutes, rounded up to the nearest whole minute; • Curve Number (CN), which is determined by Cover Types and Hydrologic Soils Groups; and • Drainage Area (A) in acres. If the drainage basin is over 20 acres, or if it contains areas of different land - - Formatted: indent: Left: 1.25", First line: o" uses, the drainage basin should be divided into sub -basins. Each sub -basin should have similar land uses. When sub -basins are used, the following information is required to use the SCS Method to determine the peak rate of runoff, or to develop a runoff hydrograph: • 24-hour total rainfall, and rainfall distribution type. The 24 hour precipitation rate is based upon NOAA values at the Roanoke Airport. • Time of Concentration (Q in minutes for each sub -basin, rounded up to the nearest whole minute; • Curve Number (CN), which is determined by Cover Types and Hydrologic Soils Groups, for each sub -basin; COUNTY OF ROANOKE 7444X/1/16 4-8 STORMWATER HYDROLOGY STORMWATER HYDROLOGY CHAPTER 4 • Drainage Area (A) in acres, for each sub -basin; and • Travel Time (Tt) of the flow from each sub -basin as it flows through downstream sub -basins. If the SCS Method is being used to design a stormwater management facility, the following additional information is required to rout the runoff hydrograph through the facility and to generate an outflow hydrograph: • Elevation — Storage Relationship • Elevation —Discharge Relationship B. �4-hour Rainfall and Distribution _ - - I Formatted: Font: sold The 24-hour rainfall is determined by ^ +44t g the map fat: toe ^ Ate Ohw p ^folk^ Valley is Tft4e 1NOAA precipitation amounts for Roanoke Airport. C. Curve Number - I Formatted: Font: sold The SCS method uses a combination of soil conditions and land use (ground cover) to assign a runoff factor to an area. These runoff factors, or runoff curve numbers (CN), indicate the runoff potential of an area. The CN requires significant judgment and understanding for proper selection. A table containing CNs for various cover types and soils conditions is contained in Appendix 4I44A. When calculating existing rates of runoff (pre -construction), assume that all cover types are in good hydrologic condition. Hydrologic Soils Groups (HSG) include types A, B, C, and D, with type A being the most permeable and type D the least permeable. Appendix 413 includes a listing of most soil names with their respective hydrologic soils types. Urban/udorthents soils shall be considered a Type D soil for design purposes. Soils maps for the Roanoke Valley may be obtained by referring to 144pi sail „sa^ oy�USDA web soil survey.

PrainageArea ................................ _ Formatted: Font: Bold Drainage areas for each sub -basin should be identified on an appropriate topographic map. E. _Elevation — Storage Relationship ------------ Formatted: Font: Bold When runoff hydrographs are being routed through a stormwater management facility, the relationship between the elevation (or depth) of stored water in the facility and storage volume needs to be known and input into the calculation. Often this information is obtained by determining the pond area bounded by contour lines on a grading plan. Enough data pairs (elevation — storage) must be provided to properly model conditions at transition points. F. _Elevation — Discharge Relationship ----------------------------- Formatted: Font: Bold When runoff hydrographs are being routed through a stormwater management facility, the relationship between the elevation (or depth) of stored water in the facility and the discharge flow rate from the facility needs to be known and input into the calculation. The development of this relationship requires an understanding of the design conditions and underlying hydraulic principles. The hydraulic principals and equations governing the discharge rate will often change several times at varying elevations. These include weir flow, orifice flow, culvert inlet control, culvert outlet control, open channel flow, and possible effects from downstream backwater. 4.7 Drainage Area Analysis To prevent the undersizing of stormwater management components, upstream properties conditions shall be considered in the drainage area analysis. Stream channel and improvements to any conveyance system shall be analyzed.

COUNTY OF ROANOKE 74/14X/X/16 4C-2 STORMWATER HYDROLOGY OPEN CHANNELS Chapter 5 — Open Channels CHAPTER 5 Open channels are man-made ditches and channels and natural channels, that are used to convey stormwater flow. This section defines criteria and restrictions to be used in designing open channels. Where open channels are a part of a BMP, they shall comply with the state requirements for the purposes of water quality improvement; however, they shall also comply with this Design Manual's requirements for water conveyance. 5.1 References The primary design references are: • VDOT Drainage Manual • VDOT Specifications • VA E&SC Handbook • Hydraulic Engineering Circular Number 15 (HEC -15), Design of Roadside Channels with Flexible Linings, Current Edition, as amended • VA SWM Handbook 5.2 Design Methodology and Criteria 5.2.1 Major and Minor Manmade Open Channels A major channel is designed to convey over 5 acres. - I Formatted: Font: Not Italic A minor channel is desisned to convey 5 acres or less. 5.2.2 Design Flow COUNTY OF ROANOKE 7444x/1/16 5-1 OPEN CHANNELS OPEN CHANNELS CHAPTER 5 j2esign flow for manmade open channels within a development is contained in - - Formatted: Font: Not Italic Chapter 4.2.2. Additionally, all storm drainage desi designs for open channels, culverts, and storm drains shall be checked for the 100 -year flow condition where there is the possibility of flooding residences, commercial or industrial buildings, overtopping primary roads, experiencing significant economic loss, or catastrophic failure. 5.2.3 Hydrology See Chapter 4 for methodology used to determine peak flows for a given design frequency. 5.2.4 Channel Hydraulics Open channel design will be based on Manning's Equation for open channel flow, unless good engineering practice dictates using HEC -RAS or other method. See the VA SWM Handbook and VDOT Drainage Manual, as appropriate. Q= A x 1.49/n x Rz/' x Slit Where: Q = Flow in the open channel (cfs) A = Cross-section area of the channel (ft) R = A/wetted perimeter (ft) S = Channel slope (ft/ft) n = Channel roughness coefficient Nomographs have been included in Appendix 5A for use in solving Manning's equation setting channel characteristics. 5.2.5 Channel Velocity The lining of minor channels with drainage areas of five acres and less shall be designed to withstand the erosive effects of a 2 -year storm. The lining of minor channels with drainage areas over five acres and major channels shall be designed to withstand the erosive effects of a 10 -year storm. The final design shall be consistent with velocity limitations for the selected channel lining, as presented in Table 5-1. Major channels associated with dam embankment spillways or other structures where catastrophic failure could result from a lining failure may be required to be designed to withstand a more severe storm event.

The design may be based on a consideration of either permissive velocity or tractive force as described in the VDOT Drainage Manual. The preferred method for analyzing channel linings is to compare the maximum permissible velocity for the channel lining, listed in Table 5.1 in this chapter of the Design Manual, to the design velocity computed using Manning's equation to verify that the selected lining is adequate. As an alternative, the selected lining may be analyzed using the Tractive Force Method published in the VDOT Drainage Manual. This method analyzes sediment critical shear loading on the open channel bottom and side slope. The permissible tractive force for various soils is located in the Appendix of the VDOT Drainage Manual. Open channels may have different lining materials in different channel reaches based on velocity and potential erosion conditions. Care must be exercised to avoid erosion at open channel transition points. The open channel lining will have an impact on the design capacity in the form of the roughness coefficient. A table of generally accepted roughness coefficient (n) for various channels and linings is included in Appendix 5A. Allowable open channel linings include the following: A. Natural _ - _- Formatted: Font: Bold To the maximum extent possible, natural channels shall be preserved. Design discharges from permitted land disturbing activities shall comply with the VA SWM Regulations. J1 _ _ Vegetative -Lined _ _- Formatted: Font: Bold Vegetated or grass -lined channels include man made channels lined with established vegetation. These channels usually include a geosynthetic mat for channel stabilization. The type of grass allowable for vegetative -lined open channels is dependant on the slope of the channel, and the peak calculated velocity. COUNTY OF ROANOKE 7444X/1/16 5-6 OPEN CHANNELS OPEN CHANNELS CHAPTER 5 Table 5-1 details the maximum permissible velocities for various channel linings. A permanent channel stabilization geosynthetic mat should be considered for all vegetated channels. There are a wide variety of geosynthetic stabilization mat options from various manufacturers. The geosynthetic mat selected should be adequate for the slope and design flow velocities calculated for the channel. Where appropriate, VDOT Road and Bridge Standard EC -2 or EC -3 may be used. Where a permanent geosynthetic mat is used to provide channel stabilization, information on the proposed mat, in the form of manufacturer's catalog information, shall be submitted as a part of the stormwater management plan. The catalog information shall include the manufacturer's recommendations for maximum allowable velocity. Design drawings must state that the geosynthetic stabilization mat shall be installed in strict accordance with the manufacturer's recommendations. Where a permanent channel stabilization geosynthetic is not used, a temporary geosynthetic lining designed to provide a measure of bank stability until such time a reasonably stable and mature stand of vegetation is established shall be provided. C.- - - Riprap-Lined-------------------------------- _ Formatted: Font: Bold The use of vegetated and geosynthetic-lined open channels for gentle - sloped open channels and concrete for steep -sloped open channels is recommended. Riprap-lined channels will not be acceptable where vegetated or geosynthetic-lined open channels are feasible. However, where design flow velocities exceed the erosive capability of a natural or vegetative -lined channel, rip rap may be used as a channel liner in areas where erosion is a concern. For an extended length of high velocity channel, consideration should be given to using a concrete channel rather than rip rap. Riprap lining shall be properly embedded in accordance with VDOT standards to maintain intended ditch cross section. Where riprap is required due to velocity conditions, it shall meet VDOT Standards and VDOT Specifications. VDOT recommended 50 percent stone size (D5o) and weight (W5o) and recommended thickness (T) for various riprap classifications is included in Appendix 5A.

Where flow is supercritical, a minimum of 12" of freeboard is required. Yard swales require 6" of freeboard. Flow is supercritical when: _ - - I Formatted: Highlight V/(32.2xH)05> 1 Where: V — velocity (fps) H — depth of flow (feet) At bends and curves, the freeboard shall be measured from the calculated water level, including the increased depth due to the superelevation of the water surface. 5.2.10 Calculation of Depth of Flow at Bends and Curves Increases in the depth of flow occur at bends and curves due to the superelevation of the water surface. Superelevation of the water surface at bends and curves is calculated by: AZ — Vz / (32.2 x r�) x (to — ri) where AZ — difference in water surface elevation between the concave and convex banks (ft) V — average velocity (ft/s) r� — radius of the center of the stream at the bend (ft) ro — radius of the outside bank of the stream at the bend (ft) ri — radius of the inside bank of the stream at the bend (ft) The increase in the normal stream flow depth at the outer bank of an open channel bend is one half of AT 5.2.11 Channel Location and Width Restrictions on Residential Lots The tops of open channel banks shall be at least 20 -feet from a residence. COUNTY OF ROANOKE 7444X/1/16 5-8 OPEN CHANNELS OPEN CHANNELS CHAPTER 5 Where manmade open channels collect stormwater from more than one lot and they are located on a residential zoned lot their use shall be restricted as follows. Where all requirements cannot be met, a closed pipe storm drain system is required. • Residential lot size 1 acre or greater o No additional restrictions. • Residential lot size 0.5 acre or greater, but less than 1 acre o Open channel top width shall be a maximum of 15 feet o Maximum drainage area passing through the open channel shall be 5 acres. • Residential lot size less than 0.5 acre o Open channel top width shall be a maximum of 15 feet o Maximum drainage area passing through the open channel shall be 3 acres. The above restrictions do not apply if any one of the following conditions is present: • The open channel is a natural channel that has adequate capacity. The retention of natural channels is encouraged. • The open channel is a perennial or intermittent stream that has adequate capacity and will remain undisturbed. • It may be demonstrated that open channels are required as a part of an integrated design to obtain the necessary water quality treatment. 5.3 Environmental Considerations and Fishery Protection Construction or modifications to open channels shall comply with all applicable laws and regulations. The applicant is responsible for procuring all necessary permits, such as US Army Corps of Engineers and VA DEQ Wetland Permits, VA DEQ VPDES Permits, etc., prior to obtaining a Land Disturbance Permit.

A culvert typically connects two open channels, but they may connect an open channel to a storm drain. Proper culvert design must consider many factors including: • Design Flow • Inlet conditions (flow approach conditions, allowable headwater, culvert inlet configuration) • Culvert conditions (material roughness, pipe slope, and length) • Tailwater depth • Buoyancy potential • Environmental considerations and effects on aquatic life • Design loads and service life of the pipe material Refer to the VDOT Drainage Manual, for a more through discussion of these items. For the design of stormwater inlets and storm drains, see Chapter 7. 6.1 References Except where more stringent requirements are presented in this Design Manual, culverts shall comply with VDOT requirements. The primary design reference is the VDOT Drainage Manual. Other appropriate references include: • VDOT Standards • VDOT Specifications • VA E&SC Handbook • VDOT Instructional and Informational Memorandum IIM-1D-121.15, Allowable Pipe Criteria for Culverts and Storm Sewers • FHWA Hydraulic Design of Highway Culverts HDS No. 5, Pub. No. FHWA- NHI-01-020, Current Edition, as amended • FHWA Debris Control Structures Evaluation and Countermeasures HEC No. 9, Pub. No. FHWA-IF-04-016, Current Edition, as amended COUNTY OF ROANOKE ;444x/1/16 6-1 CULVERTS CULVERTS CHAPTER 6.2 Design Methodology and Criteria 6.2.1 Computation Methods Manual computations use design equations and nomographs. Results are documented on VDOT's Design Form LD -269. Form LD -269 is included in Appendix 6A. There are a number of computer programs available to design culverts. Any of these computer programs will be acceptable if their methodologies are based on the same equations and nomographs accepted by VDOT, and if they provide the same documentation of inputs, assumptions, and output as are contained on VDOT's Design Form LD -269. 6.2.2 Hydrology �1. Design Flow Methodology Formatted: Font: Bold See Chapter 4 for methodology used to determine design flows. Generally culverts shall be designed based on the peak flow (steady state), ignoring the effects of temporary upstream storage. �. Obstruction Allowance Formatted: Font: Bold An obstruction allowance shall be applied in critical areas where excessive backwater may result in property damage or be a potential safety hazard. After using the appropriate design methodology to calculate the peak stormwater flow for a given frequency, an obstruction allowance will be added to the peak flow to establish the design flow rate through the culvert. The minimum obstruction allowance factor is intended to account for normal culvert obstructions, which may lower the actual capacity of the culvert once constructed, and is based on the size of the culvert pipe in accordance with the following tabulation: Culvert Size Minimum Obstruction Allowance Factor 18" and less 25% 21"-24" 20% 30" 15% 36" and greater 10% COUNTY OF ROANOKE ;444x/1/16 6-2 CULVERTS CULVERTS 6.2.3 Culvert Hydraulics CHAPTER 6 ,A._ Design Flow Formatted: Font: Bold The design flow shall be the peak flow from the following frequency storm event, plus the appropriate obstruction allowance: Roadway Storm Frequency Primary & Arterial 25 -year Secondary & Other 10 -year These frequencies are minimum values. Designing for less frequent storms may be required where there is potential damage to structures, loss of human life, injury, or heavy financial loss in the event of flooding. Compliance with the National Flood Insurance Program (NFIP) is necessary for all locations where construction will encroach on a 100 -year frequency flood plain. In addition, the 100 -year peak flow (without the addition of the obstruction allowance) shall be routed through all culverts, determining the headwater depth behind the culvert with road overtopping, to ensure that buildings and other structures are not flooded and that adjacent roadways and adjacent properties do not suffer significantly increased damage during the 100 -year storm event. Storage impacts of water behind the culvert may be considered in the calculation, but is not required. - - Formatted: Indent: Left: 1.5", First line: 0.5" ._Allowable Headwater Formatted: Font: Bold The allowable headwater is the depth of water that can be ponded at the upstream end of the culvert during the design condition, as measured from the culvert inlet invert. The allowable headwater depth shall be limited by the following conditions: • Headwater does not cause upstream property damage; • Headwater does not increase the 100 -year flood elevation, as mapped by NFIP; • During a design storm event, the water surface shall be a minimum of 18 inches below the shoulder of the road at the point where the culvert crosses COUNTY OF ROANOKE ;444x/1/16 6-3 CULVERTS CULVERTS CHAPTER under, or the low point of the road grade where the water would overtop the road; • Headwater depth shall not exceed 1.5 times the diameter or height of the culvert barrel; • Headwater depth shall not be such that stormwater flows to other ditches or terrain, which permits the flow to divert around the culvert. • The maximum overtopping depths during an 100 -year storm event for various street classifications are as follows: Classification Max. Depth at Crown Max. Velocity Local 1 ft* 6 fps Collector 1 ft* 6 fps Arterial No Overflow No Overflow Highway No Overflow No Overflow * Street overflow during a 100 -year storm will not be allowed if the street is the only means of access for 40 or more residences. A variance to this requirement may be granted if the applicant shows that the connecting roads will be experiencing substantial overtopping during a 100 -year storm and that there is no benefit to enforcing this requirement. • In most instances, the roadway overtopping may be treated as a broad crested weir. ,C._ Tailwater Conditions Formatted: Font: Bold Tailwater is the water into which a culvert outfall discharges. Culvert design shall be based on tailwater conditions that could reasonably be anticipated during the design condition. • If an upstream culvert outlet is located near a downstream culvert inlet, the headwater elevation of the downstream culvert may establish the design tailwater depth at the upstream culvert. • If the culvert discharges into a lake, pond, stream, or other body of water, the maximum water elevation of the body of water during the design storm may establish the design tailwater elevation at the upstream culvert. COUNTY OF ROANOKE ;444x/1/16 6-4 CULVERTS CULVERTS CHAPTER Inlet and Outlet Control - Formatted: Font: Bold Culvert hvdraulic design shall consider both inlet and outlet control conditions. For a culvert operating with inlet control, the flow capacity is governed by the inlet geometry. For an outlet control culvert, the inlet geometrv. barrel characteristics and tailwater elevation all impact the flow capacity. Minimum culvert performance is determined by analyzing both inlet and outlet control for a given flow and using the highest resulting headwater. (i) Inlet Control - I Formatted: Underline The following factors are considered when calculating inlet control headwater: • Inlet Area — cross sectional area of the culvert entrance face • Inlet Edge — projecting, mitered, headwall, or beveled edges are common • Inlet Shape — rectangular, circular, elliptical, or arch are common The nomograph for inlet control for circular concrete, corrugated metal and corrugated HDPE culvert pipe is included in Appendix 6A. Nomographs for calculating headwater and flow capacity for other pipe geometries are contained in the VDOT Drainage Manual. ,(ii) Outlet Control - I Formatted: Underline The following factors are considered when calculating outlet control headwater: • Manning's Roughness (n) — based on barrel material, for recommended n values, see the table in Appendix 6A. • Barrel Area — cross section perpendicular to the flow • Barrel Length • Barrel Slope COUNTY OF ROANOKE ;444x/1/16 6-5 CULVERTS CULVERTS CHAPTER 6 • Tailwater Elevation Outlet control affects the hydraulic grade line of the flow through the culvert. To calculate the hydraulic grade, reference the equations for velocity, velocity head, entrance losses, friction losses, and exit losses contained in the VDOT Drainage Manual. The nomograph for outlet control on circular concrete and corrugated metal pipe is included in Appendix 6A. For additional nomographs, cross sections, and pipe materials, see the VDOT Drainage Manual. Formatted: Font: Bold E. Culvert Velocity Outlet velocity must be checked to assure that excessive erosion and scour problems will not occur. MS 19 from the VA E&SC Handbook requires that discharges be made to an adequate channel. Culvert outlet protection shall be provided in accordance with the standards and specifications for Outlet Protection and Riprap in the VA E&SC Handbook. Culverts under roads shall be provided with end sections or endwalls in accordance with the outlet protection requirements of the VDOT Drainage Manual. Where a special design is needed to reduce outlet velocity, it shall be designed in accordance with VDOT standards. The minimum velocity in a culvert barrel must be adequate to prevent siltation at low flow rates. At a minimum this velocity shall be 3 feet per second for a 2 -year storm event. 6.2.4 Structural Design All culverts shall be designed to withstand a HS -20 highway loading, unless it crosses under a railroad, in which case the culvert shall be designed for railroad loads. The structural design shall consider the depth of cover, trench width and condition, bedding type, backfill material, and compaction. 6.2.5 Materials Culverts, both public and private, shall be constructed of materials as follows: COUNTY OF ROANOKE ;444x/1/16 6-6 CULVERTS CULVERTS CHAPTER • Culverts in the VDOT right-of-way shall be VDOT approved materials in accordance with VDOT IIM-LD-121.15 and VDOT Standard PC -1. Minimum depths of cover are shown in the PC -1 details. • Public culverts not in the VDOT right-of-way shall be: o Reinforced concrete pipe (RCP) Class III minimum or greater as required by loading conditions/cover or box. o Aluminized corrugated metal pipe (CMP), is allowed for private systems only for sizes 36 -inch diameter or smaller. Minimum gage thickness for CMP culverts shall be 16 gage for 30 -inch diameter and smaller. Minimum gage thickness for 36 -inch diameter CMP culverts shall be 14 gage. Trench design for CMP culverts shall meet ASTM or AASHTO standards. o Special CMP culverts including diameters greater than 36 -inch, elliptical, and arch designs will be considered on a case-by-case basis by the County of Roanoke for use as culvert pipe material in private storm drain systems. • Private culverts not in the VDOT right-of-way may be: o Reinforced concrete pipe (RCP) Class III minimum or greater as required by loading conditions/cover or of box. o Aluminized corrugated metal pipe (CMP), for sizes 36 -inch diameter or smaller. Minimum gage thickness for CMP culverts shall be 16 gage for 30 -inch diameter and smaller. Minimum gage thickness for 36 -inch diameter CMP culverts shall be 14 gage. Trench design for CMP culverts shall meet ASTM or AASHTO standards. o Special CMP culverts including diameters greater than 36 -inch, elliptical, and arch designs will be considered on a case-by-case basis o Corrugated high-density polyethylene (HDPE) with an integrally formed smooth interior is allowed for sizes 48 -inch diameter or smaller. HDPE culvert pipe minimum cover must be in accordance with the County of Roanoke Inspection Specifications for HDPE Pipe contained in Chapter 7-13- 11. COUNTY OF ROANOKE ;444x/1/16 6-7 CULVERTS CULVERTS 6.2.6 Culvert Sizes CHAPTER 6 The minimum culvert size shall be 18 -inch diameter, except that culverts under private entrance roads or driveways may be 15 -inch diameter if it meets all design flow conditions. Culverts shall meet all cover conditions required. Where the site conditions preclude the use of a single culvert barrel to meet the design flow conditions, multiple barrel culverts are acceptable. The maximum length of a culvert shall be 300 feet. A culvert longer than 300 feet shall have manholes or junction boxes and shall fall under the requirements of Chapter 7. 6.2.7 End Conditions End sections and headwalls shall normally be required on inlets and outlets, as described below. �1. Prefabricated End Sections Formatted: Font: sold —Prefabricated end sections, or flared end sections, provide for a better flow path, improving the design flow and headwater conditions. Prefabricated end sections shall be provided for culverts 18 -inch to 36 -inch diameter, except: • No end section is required for 15 -inch or 18 -inch diameter driveway culverts. • Where culvert alignment exceeds 20 feet in vertical elevation change or culvert slope exceeds a 2:1 slope, a standard concrete headwall shall be provided instead of a prefabricated end section. • Where a concrete headwall is provided. J._ Concrete Headwalls and Structures - - I Formatted: Font: sold Precast concrete headwalls shall be provided at all culvert inlets and outlets, unless other end conditions are allowed, as stated above. Precast concrete headwalls shall meet the requirements of the VDOT Standards and VDOT Specifications. COUNTY OF ROANOKE ;444x/1/16 6-8 CULVERTS CULVERTS CHAPTER Wingwalls may be required in conjunction with headwalls. Culvert pipes 48" or larger in diameter shall have concrete wngwalls. Wingwalls are generally used where the culvert is skewed to the normal channel flow or where the side slopes of the channel or roadway are unstable. Wingwalls shall meet the requirements of the VDOT Standards and VDOT Specifications. Wing walls shall be set at an angle between 30 degrees and 60 degrees from the headwall. Concrete aprons may be used at the entrance or the exit of culvert. Aprons are typically used where high velocities or headwater conditions may cause erosion upstream or downstream of the culvert. An apron shall not protrude above the normal stream bed elevation. Special design concrete slab end treatment, per VDOT Standards, may be used as a concrete end section. 6.2.8 Multiple Barrel Culverts Multiple barrel culverts shall be allowed where single culverts cannot handle the design flow while meeting the required cover or headwater condition requirements. The design of multiple barrels should avoid the need for excessive widening of the upstream or downstream receiving channels. The minimum spacing between culverts in a multiple barrel culvert design shall be that required to provide adequate lateral support and allow proper compaction of bedding material under the pipe haunches. 6.2.9 Culvert Skew Where possible, culverts shall be installed parallel to the flow path. The maximum allowable skew shall be 45 degrees as measured from the line perpendicular to the roadway centerline. 6.2.10 Buoyancy Verify that culvert pipe, end sections, and concrete end wall structures will not fail under hydrostatic uplift conditions. Buoyancy force consists of the weight of water displaced by the pipe and fill material that is over the pipe (below the headwater depth). The force resisting buoyancy includes the weight of the pipe, weight of the water within the pipe, and the weight of fill material over the pipe. Buoyancy is more likely to be a problem where: COUNTY OF ROANOKE ;444x/1/16 6-9 CULVERTS CULVERTS CHAPTER 6 Lightweight pipe is used Pipe is on a steep slope (usually inlet control with the pipe flowing partially full) • There is little weight on the end of the pipe (flat embankment slopes, minimum cover, and/or no endwalls) • High headwater depths (HW/D>1.0) Suitable cover, footings, or anchor blocks may be required to ensure the culvert's integrity during design conditions. 6.2.11 Debris and Trash Racks In general, trash racks or debris deflectors shall not be used where other site modifications may be made to prevent excessive trash or debris from entering the culvert. However, they may be required at specific locations, by the County of Roanoke, where large amounts of storm debris may be anticipated. 6.3 Installation All culvert pipe, headwalls, end sections, outlets, and other peripheral structures shall be installed in accordance with VDOT requirements and the manufacturer's recommendations. The characteristics of the trench, bedding, and pipe material all impact the structural strength of the pipe system. The installed culvert conditions shall comply with the design assumptions and calculations. HDPE pipe installation shall comply with the County of Roanoke's Inspection Specifications for HDPE Pipe. A copy of this installation guide is provided in Chapter 7. 6.3.1 Bedding Material Bedding material and installation shall comply with the requirements of the VDOT Specifications. 6.3.2 Backfill Backfill shall be suitable material and shall be placed and compacted in accordance with VDOT Specifications. A minimum of 12" backfill shall be placed over the top of a HDPE or CMP .- - - Formatted: indent: Left: r', First line: 0" culvert prior to placing pavement or other surface treatment. COUNTY OF ROANOKE ;444x/1/16 6-10 CULVERTS CULVERTS CHAPTER 6.4 Environmental Considerations and Fishery Protection Where compatible with good hydraulic engineering, a culvert shall be located in "dry" conditions. Where this is not possible, the culvert shall be located to minimize impacts to streams or wetlands. When a culvert is set in a perennial stream the invert of the culvert shall be set below the normal flow line of the stream as required in the VDOT Drainage Manual. The grade of the culvert shall not exceed the grade of the natural stream in the area. Where construction requires other environmental permits, the applicant shall be responsible for obtaining all necessary environmental permits and complying with their requirements. 6.5 Maintenance Requirements The permittee is responsible for maintenance of culverts until construction is complete, including final clean up and site stabilization, to the satisfaction of the County of Roanoke. After the completion of construction, the property owner or responsible party is responsible for maintenance of all culverts not located in public easements. No one shall modify culverts in any way that impairs or restricts flow. The property owner shall periodically remove silt and sediment from the pipe and prune vegetation around the pipe entrance to avoid restricting flow capacity and shall correct erosion damage as necessary. All removed silt and sediment shall be properly disposed of away from storm drainage pipes and open channels and shall be properly stabilized with vegetation.

COUNTY OF ROANOKE ;444x/1/16 6A-10 CULVERTS STORM DRAINS Chapter 7 - Storm Drains CHAPTER 7 A storm drain is a drainage system that conveys water or stormwater, consisting of two or more pipes in a series connected by one or more structures. Storm drains collect and transport stormwater from a site primarily through the use of a closed pipe network. For the storm water to be efficiently handled in a storm drain, the site must also have an efficient way to collect stormwater runoff and have it enter into the piped network. Once in the storm drain, the stormwater is routed to a discharge outfall. Storm drain systems include: Measures to get stormwater runoff to inlets, Inlets, and 4afffl Storm drain p gpipes and structures that stormwater runoff must pass through to reach the outfall This section defines criteria and restrictions that shall be used in designing and constructing public and private storm drains. See the VDOT Drainage Manual for more in-depth information. All storm drains 12 inches in diameter and larger shall have profiles prepared and submitted to the County. 7.1 References Except where more stringent requirements are presented in this Manual, storm drain collection systems shall comply with VDOT and other state requirements. The primary design reference is the VDOT Drainage Manual. Other appropriate references include: • VDOT Standards • VDOT Specifications • VA E&SC Handbook • FHWA Drainage of Highway Pavements HEC No. 12. • FHWA Urban Drainage Design Manual HEC No. 22. • VA Stormwater Management Handbook, Chapter 6 Appendix 6B (Karst Guidelines) COUNTY OF ROANOKE q444x/1/16 7-1 STORM DRAINS STORM DRAINS CHAPTER 7 7.2 Design Methodology and Criteria 7.2.1 Computation Methods Manual computations use design equations and nomographs. Results are documented on VDOT work sheets. Copies of these forms are included in Appendix 7A. • Form LD -204 Stormwater Inlet Computations • Form LD -229 Storm Drain Design Computations • Form LD -347 Hydraulic Grade Line Computations There are a number of computer programs available to design storm drainage systems. Any of these computer programs will be acceptable if their methodologies are based on the same equations and nomographs accepted by VDOT, and if they provide the same documentation of inputs, assumptions, and output as are contained on VDOT's work sheets. Computation methods are explained in detail, including comprehensive design examples, in the VDOT Drainage Manual. 7.2.2 Hydrology ,A._ _ _ Design Flow Methodology Formatted: Font: Bold Calculations establishing the design flow shall be submitted with the Stormwater Management Plan. Design flows shall be based on ultimate build -out of the contributing watershed based on the current Comprehensive Plan. 7.2.3 Design Flows The following minimum storm frequencies shall be used: A._Inlets ------------------------------------------ Formatted: Font: Bold Inlets shall be designed for storm frequencies and intensities consistent with the VDOT Drainage Manual. For reference, the VDOT table and its accompanying notes have been included in Appendix 7A. COUNTY OF ROANOKE q444x/1/16 7-2 STORM DRAINS CHAPTER 7 J._-- Storm Drains ------------------------------------- Formatted: Font: Bold Storm drains shall be designed for the storm frequencies and intensities consistent with the VDOT Drainage Manual. For reference, the VDOT table and its accompanying notes have been included in Appendix 7A. Unless otherwise specified by the VDOT Drainage Manual, a 10 -year frequency design storm shall be used in developing design flows. 7.2.4 Measures to Convey Stormwater Runoff to Inlets A._ Pavement Drainage _ _ _ _ Formatted: Font: Bold One objective in the site design is to collect and remove stormwater runoff from critical areas as efficiently as possible. A properly designed system will ensure that roadway surfaces are free of stormwater accumulations, and will protect the public from unnecessary hazards associated with water ponding and sheet flow. Except where porous pavement is used, road pavement shall be sloped transversely to drain stormwater from the roadway. A minimum cross slope of 2 percent should be applied to all roads, both primary and secondary. Greater slope should be considered where poor drainage is anticipated. Drainage structures associated with medians, curbs, and gutters should be designed to minimize accumulation of water onto travel lanes of roadways. For additional information concerning drainage of highway pavements, refer to FHWA HEC No. 12. J._ -Curb and Gutter-------------------------------- Formatted: Font: Bold Curb and gutter at the edge of pavements may be used to collect stormwater runoff from roadways. Curbing captures stormwater runoff and directs it to stormwater collection inlets while protecting adjacent properties from flooding and erosion due to sheet flow runoff from the impervious roadways. A curb and gutter forms a triangular conveyance channel. When a storm occurs, the runoff from the road creates a spread of water from the curb. The curb and gutter must be designed to convey this flow and prevent the COUNTY OF ROANOKE q444x/1/16 7-3 STORM DRAINS STORM DRAINS CHAPTER 7 spread of water from impacting traffic. The spread width of flow is determined by using VDOT nomographs or acceptable hydrological design software. For curb and gutter flow, a Manning's n value of 0.015 is used in the computational analysis. See Appendix 7A for width of maximum allowable spread. Curb and gutter dimensions and design shall meet VDOT Standards. - -C._--Open Channels------------------------------------- Formatted: Font: Bold Open channels may be used to collect site drainage and convey it to a storm drain inlet. Design requirements for open channels are covered in Chapter 5. 7.2.5 Storm Drain Inlets A. General --------------------------------------- Formatted: Font: Bold Storm drain inlets are used to collect stormwater runoff from roads, walks, or low elevations during storm events and provide a method for passing the stormwater into the storm drain system. This is usually accomplished by placing storm drain inlets at regular intervals, low points, or at key locations to intercept flows and control the stormwater spread width. The design criteria for limiting the spread of water on travel lanes are contained in the VDOT Drainage Manual. The current design table and its notes have been included in Appendix 7A There are several different types of storm drain inlets which can be used to meet this purpose, and the designer shall choose the proper inlet structure based upon site conditions and design conditions to maximize the drainage efficiencies. • Curb • Grate • Slotted Drain/Trench • Combination Drainage and Stormwater management plans shall include a contour plan with sufficient contours shown to indicate proper drainage. B. `Curb Inlets - I Formatted: Font: Bold COUNTY OF ROANOKE AW XI1/16 7-4 STORM DRAINS STORM DRAINS CHAPTER 7 Curb inlets are vertical openings in the curb covered by a top slab. These inlets can convey large quantities of water, but also allow for large amounts of debris to enter the storm drain system. Curb inlets shall be used to the maximum extent possible for pavement drainage. C. jGrate_Inlets _ _- Formatted: Font: Bold Grate inlets are horizontal grates usually used in depressed medians or other low elevations. Grate inlets are often referred to as drop inlets or DIs. Grate inlets shall be avoided in paved areas. Where they are used in pavement, inlet grates shall be bicycle safe. D. Combination Inlets ------------ I Formatted: Font: Bold Combination inlets combine both the vertical opening used by curb inlets and the horizontal grate used in grate inlets. These inlets are often used when the inlet chamber is required to be under the gutter or street pavement away from the sidewalk or other utilities. Combination inlets shall be avoided where possible. Where they are used, they FMst shall have bicycle safe grates. E. Slotted Drain Inlets _ _- Formatted: Font: Bold Slotted drain inlets are a narrow slotted opening which can collect flow at a median barrier or curb. These inlets are usually located in areas of limited space and can be used to intercept sheet flow, or collect gutter flow to help reduce ponding depth or spreading at grate inlets. F. jnlet Locations - - I Formatted: Font: Bold Inlets shall be located to meet the design requirements of the VDOT Drainage Manual for maximum spread width. In addition, inlets shall be provided, regardless of contributing drainage area as follows: • Sag points in the gutter grade; • Upstream of median breaks, crosswalks, and street intersections; • Immediately upstream and downstream of bridges; COUNTY OF ROANOKE q444x/1/16 7-5 STORM DRAINS STORM DRAINS CHAPTER 7 • On side streets at intersections, where flow is approaching the main line; • Behind curbs, shoulders, or sidewalks to drain low areas or intercept concentrated flow; and • Any low elevation in the grade. Inlets shall be avoided in pathways likely to be used by pedestrians or bicyclists. FG. Access --------------------------------------- Formatted: Font: Bold All inlets shall have a removable grate or manhole cover to allow access for clean out. All structures greater than 3 feet in depth shall be a minimum of 4° feet in diameter for maintenance access. CH` Inlet Capacities Formatted: Font: Bold The capacities of each inlet type are contained in the VDOT Drainage Manual. Documentation of inlet capacity shall be made on VDOT Form LD -204, Stormwater Inlet Computations or equivalent. SIL__ Separation of Pipes in Inlets---------------------------- Formatted: Font: Bold Where two or more pipes enter a concrete structure at or near the same elevation, a 6" minimum horizontal clearance must be maintained between the pipes. Additional clearance between pipes shall be provided if required to protect the structural integrity of the structure. IJ. Karst Terrain - I Formatted: Font: Bold Water tight joints are required where storm drainage pipe are located in karst terrain. Additionally, an A -lock premium gasket or boot is required for the pipe connection to the storm drainage structure to prevent water loss at the structure connection. 7.2.6 Storm Drain Pipes ,A.___ Flow Capacity----------------------------------- - Formatted: Font: Bold COUNTY OF ROANOKE q444x/1/16 7-6 STORM DRAINS STORM DRAINS CHAPTER 7 Based on the size and slope of the storm drain, the design capacity for a pipe flowing full can be determined using Manning's equation. Q=Ax1.49/nxW"xS"2 Where: Q = Flow in the pipe (cfs) A = Area of the pipe (ft) R = Hydraulic radius, for circular pipe R=Diameter/4 (ft) S = Storm drain slope (ft/ft) n = Pipe roughness coefficient The design flow capacity of a storm drain shall comply with the design frequencies set forth in VDOT Drainage Manual as shown in the table in Appendix 7A. In a roadway underpass, or depressed section, where ponded water can only be removed through the storm drain system, a 100 - year frequency storm event shall be used to design the storm drain at the sag point. Storm drain flow capacities shall be documented on VDOT Form LD -229, Storm Drain Design Computations or equivalent form. J1 Storm Drain Slope ..... Formatted: Font: Bold To deter the settling of debris and sediment in the storm drain pipe, the pipe shall be designed to ensure positive slope and maintain a minimum velocity of 3 feet per second during a 2 -year frequency storm or a minimum of 0.5% slope, whichever is more restrictive. A minimum drop across the structure of 0.1' shall be provided in all storm drainage structures. The maximum pipe velocity, based on the 10 -year peak flow rate, -in any storm drain shall be in accordance with VDOT requirements based on the storm drain material, but in no event shall it be greater than 20 fps. Storm drains shall be sloped to meet the velocity requirement set in this chapter. Slopes greater than 16 percent shall be avoided if possible. If unavoidable, drop structures shall be utilized in steeper terrain. In addition, storm drains with slopes steeper than 16% must have anchor blocks for support. C. Pipe Size --------------------------------------- Formatted: Font: Bold COUNTY OF ROANOKE q444x/1/16 7-7 STORM DRAINS STORM DRAINS CHAPTER 7 All storm drains located in public easements or rights-of-way shall be a minimum of 15 -inch diameter. Pipe size shall not be reduced along the direction of the flow, except as required for proper operation of stormwater management facilities. p.- --Access - ----------------------------------------- Formatted: Font: Bold Regardless of pipe size, a cleanout access point, either an inlet, manhole, or junction box shall be provided at a maximum of every 300 feet of pipe. Cleanouts can be used for pipes 6" and smaller. All pipes over 6" require an inlet or manhole. JE. ---Joints ----------------------------------------- Formatted: Font: Bold At a minimum, all joints shall be "soil tight". The County strongly recommends the use of "water -tight" joints under pavements and areas that are stormwater "hotspots". "Water -tight" joints are required for karst terrain. See Section IV and corresnondine ADS detail in ADDendix 7B for additional info in water tight joints 7.2.7 Determination of Hydraulic Grade Line A. General --------------------------------------- Formatted: Font: Bold The hydraulic grade line represents the free water surface elevation of water in a pipe system. Where the hydraulic grade line is above the top of a pipe, the pipe is flowing under pressure. The hydraulic grade line in a manhole or other structure is the elevation to which water will rise. Hydraulic grade lines shall be calculated and evaluated for all storm drains. The hydraulic grade line shall be calculated using VDOT methods and equations that are fully described in the VDOT Drainage Manual. Calculations shall be documented on VDOT Form LD -347, Hydraulic Grade Line Computations, or equivalent. A copy of this form is included in Appendix 7A. Hydraulic grade lines can also be calculated with design software (ie Storm sewer, etc.) The hydraulic grade line shall not exceed any critical elevation during the design storm. Critical elevations include rising above the ground COUNTY OF ROANOKE q444x/1/16 7-8 STORM DRAINS STORM DRAINS CHAPTER 7 elevation at inlets or other structures, or reaching an elevation where storm flow could back-up to cause flooding damage. The calculation of the hydraulic grade line begins at the system outfall and proceeds upstream to each structure on the system. The calculation is based on the principal of conservation of energy as shown below and includes major and minor energy losses: HGL„s= HGLd, + Hf+ Hm Where: HGL, _ _ Elevation of hydraulic grade line at the upstream structure Hm = Summation of minor head losses (junctions, bends, etc.) Hf =_ Pipe friction loss HGLds Elevation of hydraulic grade line at the downstream structure Major head losses are attributable to friction losses within the pipe. Minor head losses include losses from: • Junctions • Exits • Entrances • Bends in Pipes • Access holes • Conflict pipes • Plunging flow • Expansions and contractions • Appurtenances such as weirs, diverters, valves and meters B. Outfall Conditions Formatted: Font: Bold The hydraulic grade line starts at the system outfall. At this point the hydraulic grade line shall be the actual tailwater elevation or the elevation of 0.8 times the diameter of the outlet pipe, whichever is higher. If the system discharges into a detention or retention pond, the hydraulic grade shall start at the 10 year water surface elevation. C. JPipe Friction Losses Formatted: Font: Bold The friction slope is the energy slope for that run of pipe. The friction slope is determined by inserting pipe information and design flow into COUNTY OF ROANOKE q444x/1/16 7-9 STORM DRAINS STORM DRAINS CHAPTER 7 Manning's equation and solving for S (slope). The total friction headloss in the run of pipe is the friction slope multiplied by the length of the run. Where the hydraulic grade line falls below the crown of the pipe, the elevation of normal flow is the hydraulic grade line. Formatted: Fait: Bold D. Junction Losses J. General - I Formatted: Underline Junction head losses are the summation of entrance (Hi), exit (Ho), and bend losses (Ho). When calculating junction losses it is important to use actual flow velocities. If pipes are flowing partially full, then partially full velocities are used. 2. Entrance (expansion) Losses - I Formatted: Underline Entrance loss at a junction is given by: H;=K;(V,2/2g) Where: Hi= Entrance head loss Ki = Entrance loss coefficient.

If the inlet and outlet pipe are in line with one another no bend) the angle is 0 degrees and there is no bend loss. As the angle increases towards 90 degrees, the bend loss increases. Storm drain systems should not be designed with bend angles greater than 90 degrees. The bend loss is given by: Ho = K (V;z / 2g) Where: - - Formatted: Indent: Left: 1.75", First line: W - - Formatted: Indent: Left: 1.75", First line: W Ho = Head loss at bend K = Bend loss coefficient. K is determined by consulting Figure 9-10 in the VDOT Drainage Manual. A copy is included in appendix 7A. Vi = Velocity in the inlet pipe. g = Gravitational acceleration constant, 32.2 ft/s2 5.

When VDOT Standard IS -1, inlet shaping, is used in a structure the total headloss from the structure (Hi +Ho + Ho) shall be multiplied by 0.5 (decreased by 50 percent). This adjustment is cumulative with the adjustment for plunging losses. 7.2.8 100 -Year Conditions COUNTY OF ROANOKE q444x/1/16 7-11 STORM DRAINS STORM DRAINS CHAPTER 7 Where there is the possibility of building structures flooding, conditions during .- - - Formatted: Indent: Left: r', First line: 0" the 100 -year storm shall be analyzed to verify that all existing and proposed structures do not flood.

' At locations where the vertical alignment of the roadway creates a sag condition in either a depressed roadway section or a roadway section utilizing concrete barriers, and ponded water on the roadway can only be removed through the storm drain system, a 50 -year storm frequency and the actual time of concentration should be used as the design criteria for both the drop inlet and the pipe system. 2 Federal Flood Insurance criteria dictate that the effects of the 100 -year storm event (using the actual time of concentration) on buildings insured under the Flood Insurance Program must be investigated. Such cases should only be encountered where the roadway traverses a designated floodplain area containing insured buildings and the depth of water on the pavement is sufficient to overtop the curb and flow to the buildings. 3 The maximum design spread width may not be obtainable due to the pavement/shoulder slope and the height of the curb. In locations where the curb would be overtopped and water would escape the roadway section prior to achieving the maximum design spread with, the maximum depth of ponded water allowed adjacent to the curb for the design storm shall be curb height minus one (1) inch. Notes 4 through 5 should normally be applied to the specific locations as noted in the criteria table. 4 At location where it may be reasonably anticipated that the runoff from storm events with rainfall intensities greater than 4 inches per hour will overtax the drop inlet system to the point that excess flow will escape the roadway section and result in potential damage to the adjacent property and/or roadway right of way, the drop inlet system shall be analyzed for a check storm event with a rainfall intensity of 6.5 inches per hour. If all of the runoff from the check storm event is found to be contained within the roadway section, both at the site and down grade, or if runoff escaping the roadway section is found to not be damaging to adjacent property, the drop inlet system may be used as originally designed under the general criteria. If the drop inlet system fails to meet the check storm criteria, it must be re -designed to accommodate the runoff from the check storm event. 5 Drop inlets in these locations are prone to clogging and are often located in areas where maintenance is difficult. To compensate for partial clogging, the computed slot length value should be adjusted by multiplying by a factor of two (2). The adjusted computed slot length value should then be used to determine the slot length specified on the plans.

Typical Details APPENDIX 711 COUNTY OF ROANOKE q444x/1/16 7B-2 STORM DRAINS STORM DRAINS I_ OVERVIEW APPENDIX 7B The County of Roanoke, in conjunction with the Virginia Department of Transportation, is allowing HDPE pipe for storm sewers. HDPE pipe may be used for any size up to 48" in diameter. Anything above that must use previously approved pipe material. 11. PRE-INSTALII ATION A. Trench "Widths Trench widths used in installing HDPE pipe have been established in AASHTO Section 30 and ASTM D2321. Table 1 provides the recommended trench widths for most installations to provide the proper placement and compaction of backfill material in the haunches around the pipe. Trenching should be completed in the existing soils with sidewalls reasonably vertical to the trip of the pipe. When excavation depths or soil conditions require shoring or use of a trench box, the bottom of the shoring or trench box should be placed no lower than the top of the pipe. This prevents disruption of the backfill when shoring of trench box is removed. If this practice cannot be followed, considerations should be given to leaving the shoring in place. Refer to Table 1.

Dewatering APPENDIX 7B HDPE pipe will float in standing water. Therefore, it is imperative that the trench be dry when installing the pipe. Sump pumps, well points, or other methods may be needed to insure a dry trench. Ill[. EMBEDMENT Embedment materials are those used for the foumdation, bedding, haunching, and initial backfill. An illustration of this can be found in Figure I page 5. A. Definitions I . Class I — Angular crushed stone or rock (No. 25 or 26 stone). 2. Class. 11— Clean, course grained materials, such as gravel, course sands, and gravel/sand mixtures. 3. Class 111— Course grained materials with fines including silty or clayey gravels or sands. Gravel or sand must comprise more than 50% of Class III materials. 4. Class N and. V materials are not recormnended for embedment materials. B. Foundation A stable foundation must be provided in order to insure proper installation. Unsuitable or unstable foundations maybe replaced with a suitable bedding material, placed in 5" lifts. COUNTY OF ROANOKE q444x/1/16 713-4 STORM DRAINS STORM DRAINS C. Bedding APPENDIX 713 4 The middle of the bedding, equal to 1/3 of the pipe outside diameter, should be loosely placed. The remaining stone for the bedding should be compacted to a minimum 90% standard proctor density. Class i stone will be acceptable material for use, except when the f6tindation is in soft, yielding, or otherwise unsuitable material.. Then, the bedding material shall be #57 stone for the specified depth, and then capped with. 4" of Class I stone. D. Haunching Haunching provides the pipe with its main support and strength. Extra care must be taken in installing the haunching. The haunching will extend from the bottom of the pipe up to the spring line. For larger diameter pipes (30"- 48"), embedment materials should be worked in by hand. Class I stone may be used and compacted in 8" maximum lifts, compacted to 90% standard proctor density. E. Initial Backfill Initial Backfill will extend from the spring line to 12" above the top of the pipe. The backfill material shall consist of Class I stone, compacted in 6" lifts, compacted to 90% standard proctor density. F. Final Backfill Final back fill should be the same material as the proposed embankment. Generally, the excavated material will be used for the final backfill. The final baelcEll is to he placed in 12" niaxinmrn lifts, compacted to a minimum 85% standard proctor compaction.

JOINTS For watertight joints, an ASTM F-477 elastomeric rubber gasket shall be used at all joints of pipe. To install this gasket, the ends of the two pipes being connected shall be cleaned. The gasket shall be applied onto the bell with the marking facing the coupler. Apply lubricant liberally to both joints of the pipes. Align the pipe to push it together on grade. Generally, pipe should be laid from the downstream end and working upstream. 'Small diameter pies (>24") can be pushed together by hand. Larger diameter pipes may need to use a bar or equipment to push the pipe together. if that is used, a wood block should be used to prevent any damage to the bell of the pipe. Special care should be taken to ensure that no bedding material gets into the joints. Stone or any other material that gets into the joint may cause leaks_ Rubber gaskets are normally installed at the factory. However, if a pipe needs to be cut in the field, the gasket shall be stretched over the bell prior to connecting pipes together.

In addition to providing flood control, stormwater detention facilities can protect downstream channels from increases in erosion ara ide a w was„ e ,.F,.,,.*Rr gida4. *re&r**. This chapter addresses general requirements for detention facilities as they relate to attenuating peak flows. mss - When a storm event occurs, stormwater runoff enters the detention facility. The outlet structure allows a portion of the stormwater runoff to discharge from the facility and the remainder of the stormwater runoff is temporarily stored. After the end of the storm, water continues to discharge from the facility until it is empty. Stormwater detention facilities include: • Detention Basin • Retention Basin • Extended Detention Basin • Enhanced Extended Detention Basin • Underground Detention A detention basin is a pond that is normally dry. When a storm event occurs, it temporarily stores stormwater runoff, discharging it at a controlled rate through a hydraulic outlet structure to a downstream conveyance system. A retention basin is a stormwater pond which includes a permanent pool, even during non - rainfall periods. The pond includes storage above the normal pool elevation which temporarily stores stormwater runoff during storm events. An extended detention basin is a pond which temporarily stores runoff for a specific time period following a storm event, discharging it at a controlled rate through a hydraulic outlet structure to a downstream conveyance system. An extended detention basin is dry during non -rainfall periods. An extended detention basin provides more protection to the downstream channel from increases in erosion than a detention basin by releasing stored runoff at a lower rate over a longer time period. A typical plan and profile for an extended detention basin are detailed in the VA MP Clearinghouse. An enhanced extended detention basin is similar to an extended detention basin, but it also incorporates a shallow marsh in its bottom to : ae ,.4dit: ona alis , 40A*m04* ,.,.:,.,. ,,:............. :r C,.,.. tff 11.

In addition to detention and retention basins, the design requirements specified by this chapter and the VA BMP Clearinghouse shall apply to ponds created as private property amenity features.afta�. 9.1 References Except where more stringent requirements are presented in this Manual, the design and construction of stormwater detention facilities shall comply with VDOT and DCR VA BMP Clearinghouse requirements. The primary design references are: • VA SWM Handbook • VDOT Drainage Manual • VA E&SC Handbook • VDOT Standards • VA BMP Clearinghouse 9.2 Design Methodology and Criteria 9.2.1 Hydrology See Chapter 4 for methodology used to determine design flows. 9.2.2 Design Flows and Storage Volumes To properly design stormwater detention facilities, a flow routing program shall be used with an appropriate elevation — discharge - storage relationship for the design storm events. 9.2.3 Minimum Contributing Drainage Area A stormwater retention basin, which contains a permanent pool, requires at least 10 acres of watershed drainage and/or a good source of base flow to maintain the permanent pool. A minimum drainage area of 20 acres shall be used when the basin is located in an area of high visibility to prevent unsightly drying of the permanent pool. Retention basins are best suited for regional and large drainage area projects. COUNTY OF ROANOKE x/1/16 9-2 STORMWATER DETENTION STORMWATER DETENTION 9.2.4 Detention Facility Locations CHAPTER 9 Stormwater detention facilities should not be constructed within a Federal Emergency Management Agency (FEMA) designated 100 -year floodplain. If this is unavoidable, the facility shall comply with all applicable regulations under the National Flood Insurance Program, 44 CFR Part 59._ The following factors shall be addressed when siting a stormwater detention facility: • Geotechnical conditions including soil conditions; • Groundwater levels and it's potential impacts; • Karst topography; • Existing and proposed utilities; • Aesthetics on surrounding properties; and • Environmental impacts including wetlands. Stormwater basins shall be located to minimize the aesthetic impacts to the surrounding property. Basins shall be set back from property lines a distance equal to the minimum width of the applicable required buffer yard. Locate stormwater detention facilities to avoid collecting significant amounts of drainage from offsite areas. Stormwater basins shall be set back at least fifty feet from a residential dwelling structure as measured from the wall of the structure to the top of the basin embankment. In proposed single family residential subdivisions, the stormwater management facility shall be located in a single non-developed lot. 9.2.5 Basin Grading Stormwater basins shall be graded to blend into the surrounding topography with the following conditions: • Basin side slopes shall be no greater than 3:1. • Provisions shall be made for the long-term maintenance of basin slopes and periodic access for maintenance of the outlet structure, emergency spillway, and removal of accumulated sediments. COUNTY OF ROANOKE x/1/16 9-3 STORMWATER DETENTION STORMWATER DETENTION CHAPTER 9 • The maximum allowable depth of a stormwater detention basin shall be 15 feet, as measured from the top of the embankment to the lowest point in a basin. • The bottom of the basin shall have a low flow or pilot channel to facilitate complete drainage. The pilot channel shall convey flows from a 2 year storm event and prevent standing water during dry -weather conditions. The pilot channel shall be sloped a minimum of 2% if it is a grass -lined channel and at a minimum of 1% if concrete -lined. In addition to the above requirements, the follow standards of practice should be used when designing a stormwater basin to the extent possible: • The length -to -width ratio of a stormwater basin should be a minimum of 2:1. A 3:1 ratio is desired where possible. This prevents short-circuiting of the basin's storage areas. • To minimize cut and fill, the long dimension of a stormwater basin should run parallel to the contours. 9.2.6 Embankments and Emergency Spillways Stormwater basin earthen embankments shall be designed and constructed to maintain structural integrity during the 100 -year frequency storm event. When applicable, Virginia Dam Safety regulations shall apply. The minimum top width of an embankment shall be 10 feet. Width may be greater based on the overall height. Embankment side slopes shall be no steeper than 3:1. Embankments with an emergency spillway must provide at least one foot of freeboard from the maximum 100 year storm water surface elevation to the top of the embankment. An embankment without an emergency spillway must provide at least two feet of freeboard from the maximum 100 year storm water surface elevation to the top of the embankment. A geotechnical study shall be required for all stormwater basins with constructed embankments greater than 6 feet in height as measured from the base of the embankment.

The commented [AG1]: geotechnical study shall be performed by a licensed geotechnical engineer or licensed geologist and the report submitted to the County. COUNTY OF ROANOKE x/1/16 9-4 STORMWATER DETENTION STORMWATER DETENTION CHAPTER 9 9.2.7 Outlet Structures and Release Rates Stormwater Release Rates - Formatted: Font: Bold Stormwater detention facilities shall be designed with an outlet structure to control the release rate from stormwater being held in the facility. Design release rates shall meet the requirements set forth in Chapter 4, except that extended detention facilities shall be designed based on releasing the design storm runoff volume in a prescribed time as indicated in the VA MP Clearinghouse. All stormwater detention facilities shall be empty within 72 hours following the storm event. Ponds created as private property amenity features, not being used as stormwater management, shall be exempt from release rate requirements. J._ Outlet Structure Criteria - Formatted: Font: Bold Outlet structures generally include a principal spillway or outlet and an emergency overflow. An outlet structure may take the form of a drop inlet, pipe, weir, or orifice. The principal spillway or outlet is intended to release flow from the design storm events at the necessary controlled rate, without allowing flow to enter the emergency spillway or overflow. The sizing of the outlet structure shall be based on the results of the hydrologic routing calculations or model. —Pile *H the *e4gdetiey E4 el,.ggit , *'+e Outlets from stormwater detention facilities shall be designed to function without manual, electrical, or mechanical controls. Where necessary, energy dissipaters shall be placed at the outfall to provide a non-erosive velocity from the facility to a channel. See Chapter 10 for the design of outfall protection. Where a stormwater basin with an earthen embankment does not have an emergency spillway, the principal outlet or spillway shall be sized to safely pass the flow from the 100 -year frequency storm without over topping the earthen embankment. In this instance, the design of the primary outlet structure shall include a 50% clogging factor duringtie 100 -year frequency storm as a safety factor. When the primary spillway is less than 24 inches wide. it shall be considered inoperative during a 100 - ear frequency storm COUNTY OF ROANOKE x/1/16 9-5 STORMWATER DETENTION STORMWATER DETENTION CHAPTER 9 Where a stormwater basin with an earthen embankment has an emergency spillway included, two conditions must be evaluated. The routed 100 -year WSEL must provide one foot of freeboard between the 100 -yr WSEL and the top of the berm. Secondly, the spillway must be evaluated to show that the 100 -year flow passes through the spillway without overtopping the berm. Both conditions must be evaluated and met. The ability to pass the 100 -year now through the spillway is typically evaluated by routing the flow through the spillway only with all other outlets ignored or by simply evaluating the 100 -year flow through the dimensional equivalent weir using F1owMaster, similar software, or applicable weir equations. Where a stormwater basin with an earthen embankment does not have an emergency spillway included, two conditions must be evaluated. The routed 100 -year WSEL must provide two feet of freeboard between the 100 -year WSEL and the top of the berm. Secondly, the principal outlet or spillway (riser weir or culvert outlet) shall be sized to safely pass the 100 - year frequency storm without overtopping the beim. For this condition, the evaluation shall include a 50% clogging factor and is typically evaluated assuming a weir length (perimeter) or culvert (diameter) based on dimensions providing 50% of the design flow area. The principal spillway must be a minimum of 24 inches wide/diameter unless calculations show that the freeboard requirements and no overtopping conditions are met. For examples of design calculations of outlet structure orifices and weirs, see the VDOT Drainage Manual and VA MP Clearinghouse. All riser structures shall be cast -in-place or precast concrete, unless a substitute material has been approved by the County. VDOT standards for riser structures may be found in the VDOT Standards. Outlet pipes shall be reinforced concrete pipe with rubber gasket watertight joints, shall have appropriate seepage control, and shall be installed on a concrete cradle from the tie of the pipe to the riser for the entire length of the outfall pipe. Concrete cradle shall be in accordance with the requirements of the VDOT Standards. C.

Selection and plant installation shall be in accordance with the standards of the VA SAIN 9*R44ee4BMP Clearinghouse. Trees and shrubs shall not be planted within a stormwater detention basin, nor on a stormwater basin berm, dam, or emergency spillway. The VA MP Clearinghouse shall be utilized for guidance for landscaping in the marsh areas of enhanced extended detention basins. Native plants will be used to the maximum extent possible. 9.2.10 Underground Detention �. -- Materials-------------------------------------- Formatted: Font: Bold All materials used in underground detention facilities shall be corrosion resistant consisting of reinforced concrete, aluminized corrugated metal pipe, corrugated high density polyethylene pipe, or similar approved material.

Providing pre-treatment to remove sediments before or at the entrance of the underground detention facility to improve water quality and/or improve maintainability should be considered during the design. 9.2.11 Trash Racks Outlet structures shall be equipped with an appropriate trash rack. The trash rack shall be in accordance with the VA MP Clearinghouse. 9.3 Environmental Impacts Environmental impacts shall be carefully considered when siting stormwater detention facilities. Siting basins in low lying areas with potentially environmentally sensitive areas requires careful consideration, coordination, approval, and permitting with local, state, and federal agencies to evaluate the suitability of constructing in these areas. Environmentally sensitive areas include, but are not limited to wetlands, shallow marshes, jurisdictional waters, natural watercourses, wildlife habitat, etc. and may be protected by state and/or federal laws. With careful planning, it may be possible to incorporate wetland mitigation into the basin design. Construction of stormwater basins or modifications to existing basins shall comply with all applicable laws and regulations. The applicant is responsible for procuring all necessary permits, such as US Army Corps of Engineers and Virginia DEQ Wetland Permits, Virginia DEQ VPDES Permits, VSMP Permits, etc., prior to beginning construction. Copies of all permits shall be provided to Roanoke County prior to a land disturbing permit being issued. See Chapter 12 for more information. Detention facilities shall be coordinated with a watershed or regional plan for managing stormwater runoff, if available. 9.4 Maintenance Requirements For the post -construction maintenance of stormwater detention facilities, see Chapter 14. COUNTY OF ROANOKE x/1/16 9-8 STORMWATER DETENTION ENERGY DISSIPATION Chapter 10 - Energy Dissipation CHAPTER 10 Outlet protection for culverts, storm drains, BMP outlets, and steep open channels is essential to preventing erosion from damaging downstream channels and drainage structures. Erosion problems at culverts or at the outlet from detention basins are a common occurrence. Determination of the flow conditions, scour potential, and channel erosion resistance shall be standard procedure for all designs. Outlet protection can be a channel lining, structure, or flow barrier designed to lower excessive flow velocities and prevent erosion and scour. Outlet protection shall be employed whenever the velocity of flow at a pipe or open channel outlet exceeds the erosive velocity of the immediate downstream reach. Energy dissipation may take the form of the following: • Erosion control stone -lined channels; • Riprap outlet basins; or • Concrete baffled outlets. 10.1 References Except where more stringent requirements are presented in this Design Manual, energy dissipators shall comply with VDOT and other state requirements. The primary design references are the VDOT Drainage Manual and the VA E&SC Handbook. Other appropriate references include: • VDOT Standards • VA SWM Handbook • FHWA Design of Riprap Revetment HEC No. 11 (Pub. No. FHWA-IP-89-016 1989/2000) • FHWA Hydraulic Design of Energy Dissipators for Culverts and Channels HEC No. 14 (Pub. No. FHWA-EPD-86-110 Sept. 1983 & FHWA-IF-00-02 2000) • U.S. Dept. of the Interior — Bureau of Reclamation: Hydraulic Design of Stilling Basins and Energy Dissipators (Engineering Monograph No. 25) COUNTY OF ROANOKE q444x/l/16 10-1 ENERGY DISSIPATION ENERGY DISSIPATION CHAPTER 10 • U.S. Dept. of the Interior — Bureau of Reclamation: Design of Small Canal Structures 10.2 Design Methodology and Criteria 10.2.1 Outlet Velocity Where the outlet velocity from culverts, storm drain outfalls, or open channels is high, and channel or pipe modifications cannot adequately reduce the velocity, energy dissipation may be necessary. See the VDOT Drainage Manual Sections 7.4.6 and 8.3.2 for methodologies to determine design outlet velocities from open channels, culverts, and storm drains. For the calculation of open channel velocity, see Chapter 5. For the calculation of exit velocity from culverts, see Chapter 6. For the calculation of exit velocity from storm drain pipes, see Chapter 7. 10.2.2 Erosion Control Stone The most common form of energy dissipation is the use of erosion control stone at the outlet. Protection is provided primarily by having sufficient length and flare to dissipate energy by expanding the flow. The outlet velocities are computed for the VDOT design discharge. mid the 25 year diseha+ge. Wh:,.he , ,.i,.e4y is .r Where a pipe discharges into a channel, the apron shall extend across the channel bottom and shall extend up the bank to a depth of one foot above the maximum tailwater depth from the design storm event. The dimensional requirements of the erosion control stone apron shall be determined using the graphical curves in the VA E&SC Handbook. Generally, the use of erosion control stone for energy dissipation is limited to a maximum velocity of 19 feet per second. Alternative means of energy dissipation shall be required where the discharge velocity is greater than 19 feet per second. Alternative means include riprap outlet basins or concrete baffled outlets. The use of alternative means of energy dissipation requires the approval of VDOT when located in a VDOT right-of-way. 10.2.3 Riprap Outlet Basins COUNTY OF ROANOKE q444x/l/16 10-2 ENERGY DISSIPATION ENERGY DISSIPATION CHAPTER 10 A riprap basin is a depressed area of riprap placed at the outlet of a high velocity culvert, storm drain outlet or open channel. The riprap reduces the exit velocity by expanding the flow over the riprap length and width and forming a hydraulic jump. For the design of riprap basins, refer to the VDOT Drainage Manual. Dissipator geometry may also be computed using the "Energy Dissipator" module that is available in the computer program FHWA HY8, Culvert Analysis. Details of the riprap basin energy dissipator are included in Appendix 10A. 10.2.4 Baffled Outlets A baffled outlet usually consists of a concrete box structure with a vertical hanging concrete baffle and an end sill. Several variations of concrete baffled outlets have been published by VDOT and other state and local transportation and stormwater management agencies. A typical schematic of baffled outlets are shown in Appendix IOC. Baffled outlets are usually used when very high exit velocities exist at piped or channel transitions. Baffled outlets function by dissipating energy through impact of the water hitting the baffle and through the resulting turbulence. A tailwater depth is not required for adequate energy dissipation, but will help smooth the outlet flow. This type of outlet protection may be used with outlet velocities up to 50 feet per second. Baffled outlets are not included in state guidance handbooks. Hydraulic design procedures for baffled outlets may be found in the U.S. Department of Interior, Bureau of Reclamation, Design of Small Canal Structures, 1978 and are as follows: Step 1: Determine input parameters, including: H = _—Energy head to be dissipated, feet (can be approximated as the difference between --channel invert elevations at the inlet and outlet). Where: Q = Design discharge, cubic feet/second v = Theoretical discharge velocity determined from 2 g H, feet/second A = Flow area, Q / v, feetz COUNTY OF ROANOKE q444x/l/16 10-3 ENERGY DISSIPATION ENERGY DISSIPATION CHAPTER 10 d = Flow depth entering the basin, ft Fr = Froude number = v / ( g d )0 5, dimensionless g _Gravitational constant = 32.2 feet/second2 Step 2: Calculate the minimum basin width, W, in feet, using the following equation: W / d = 2.88 (Fr)"" Where: W = minimum basin width, feet d = depth of incoming flow, feet Fr = Fronde number = v / ( g d )0s The limits of the W/d ratio are from 3 to 10, which corresponds to Fronde numbers 1 to 9. If the basin is much wider than W, flow will pass under the baffle and energy dissipation will not be effective. Sten 3: Calculate other basin dimensions as a function of W. Refer to the Schematic of Baffled Outlet in Appendix LOCA for other dimensions as a function of W and to identify variables that are used below in other steps. Sten 4: Calculate the reauired Drotection for the transition from the baffled outlet to the natural channel based on the outlet width. A riprap apron shall be added of width W, length W (or a 5 -foot minimum), and depth f (W/6). The side slopes shall be 1.5:1, and the median rock diameter shall be at least W/20. Sten 5: Calculate the baffled outlet invert elevation based on the expected tailwater. The maximum distance between expected tailwater elevation and the invert should be b+f or some flow will go over the baffle with no energy dissipation. If the tailwater is known and fairly controlled, the baffled outlet invert should be a distance ( b / 2 ) + f below the calculated tailwater elevation. If tailwater is uncontrolled, the baffled outlet invert should be a distance f below the downstream channel invert. COUNTY OF ROANOKE q4/44x/1/16 10-4 ENERGY DISSIPATION ENERGY DISSIPATION CHAPTER 10 Step 6: Calculate the outlet pipe diameter entering the basin assuming a velocity_ of 12 fps flowing full. Step 7: If the entrance pipe slopes steeply downward, the entrance pipe shall be turned horizontal for at least 3 feet before entering the baffled outlet. Step 8: If it is possible that both the upstream and downstream ends of the pipe will be submerged provide an air vent approximately 1/6 of the pipe diameter near the upstream end to prevent pressure fluctuations and possible surging flow nnnditinnc 10.2.5 Energy Dissipator for Paved Areas For energy dissipation from velocities from paved channels or flumes, use VDOT Standards. Schematics of energy dissipators for paved flumes has been included in Appendix IOC. 10.2.6 Additional Energy Dissipators For additional energy dissipators, refer to FHWA HEC No 14 entitled, Hydraulic Design of Energy Dissipators for Culverts and Channels. 10.3 Installation Requirements Energy dissipators shall be installed and constructed according to all applicable FHWA, VDOT, and other state requirements and recommendations. 10.4 Easements Where an energy dissipater will be owned by a public jurisdiction or agency, a drainage easement must encompass the entire energy dissipator, and provide an additional area 10 feet wide around the entire energy dissipator to provide for maintenance. 10.5 Environmental Impacts Construction or modifications to energy dissipation structures shall comply with all applicable laws and regulations. The applicant is responsible for procuring all necessary permits, such as US Army Corps of Engineers and VA DEQ Wetland Permits, etc. 10.6 Maintenance Requirements The permittee is responsible for maintenance of energy dissipation structures until construction is complete, including final clean up and site stabilization, to the satisfaction of the County. After the completion of construction, property owners or responsible COUNTY OF ROANOKE q444x/l/16 10-5 ENERGY DISSIPATION ENERGY DISSIPATION CHAPTER 10 parties are responsible for maintenance of all energy dissipation structures located in private easements.

The following type of areas are considered to be "environmentally sensitive": • Floodplain —Areas identified within a 100 -year recurrence interval flood plain. • Steep Slopes — Areas with a slope of 33 percent or greater. • Stream Buffers —Setbacks and vegetative buffers established adjacent to the Roanoke River as required by the County of Roanoke zoning ordinance or designated conservation area buffer zones at each bank of streams, ponds, lakes, wetlands, and stormwater BNWs. • Critical Erosion Areas — Areas with potential serious erosion problems as defined in the VA E&SC Handbook. These fall into two sub categories. o The erosion hazard is critical if the slope length exceeds the following criteria: 0-7% slope > 300 feet 7-15% slope > 150 feet >15% slope > 75 feet o Areas may be critical if the soils are highly erodible, as classified using the United States Department of Agriculture (USDA) Natural Resources Conservation Service (formerly Soil Conservation Service) methods, either Land Capability Classification IIIe, IVe, IV, VII, or VIII or with an erodibility index factor greater than 8. • Karst Geology — Areas where the underlying geologic conditions include caves and crevices which allow stormwater to infiltrate and quickly migrate and transport potential pollutants. • Hot Spots — Areas where a high potential for stormwater pollution may occur due to current or former activity on the site. • Jurisdictional Streams and/or Water — Waters regulated by U.S. Army Corps of Engineers (USACE) under Section 404 of the Clean Water Act. A jurisdictional determination (JD) is required that identifies and separates the Corps regulated areas from non-regulated areas. Disturbance in regulated areas requires a permit form USACE. JDs are typically good for 5 years after the determination has been made by COUNTY OF ROANOKE 9 44X/x/16 12-1 ENVIRONMENTALLY SENSITIVE AREAS OWLTAR1410041WN1►:\1 W&IBWYY\IIW.1N R X11 MyY0II'M IPJ the USACE.

A iurisdictional determination (JD) is required that identifies and delineates wetlands. Disturbance in wetlands requires a permit form USACE. JDs are typically good for 5 years after the determination has been made by the USACE. Third party reports by qualified professionals will be accepted for wetland delineation. 12.1 References The following publications may be useful in providing guidance when performing construction, establishing development limits, and developing appropriate strategies and design features to address the special concerns related to environmentally sensitive areas: • VDOT Drainage Manual • VA E&SC Handbook • VA SWM Handbook • Virginia Department of Conservation and Recreation, Technical Bulletin No. 2, Hydrologic Modeling and Design in Karst • International Building Code • The Development of the Land Capability Classification (reprinted from Readings in the History of the Soil Conservation Service), Douglas Helms, Soil Conservation Service, 1992 • Clean Water Act Section 404 • River & Harbors Act of 1899 Section 10 • FEMA Flood Map Service Center • Flood Insurance Rate Map (FIRM) COUNTY OF ROANOKE 9 44X/x/16 12-2 ENVIRONMENTALLY SENSITIVE AREAS ENVIRONMENTALLY SENSITIVE AREAS CHAPTER 12 12.2 Floodplains The purpose of floodplain management is to regulate the use of the floodplains in order to protect life and property, prevent sedimentation and pollution of water resources, and to prevent or protect against the general degradation of the environment. Floodplains and their regulatory requirements are generally based on the stream flows generated by a 100 -year frequency storm and existing land development conditions. However, storms and future land development can generate flows of greater magnitude and flooding above and beyond these limits. For this reason, additional vertical and horizontal setbacks from the floodplain limits are strongly encouraged to account for future development within the upstream drainage area and to serve as a factor of safety for larger flood events. Floodplains include: • Areas identified within a 100 -year recurrence interval floodplain as identified by the Federal Emergency Management Agency (FEMA). These areas have been identified as the Floodplain Overlay District by the County of Roanoke Zoning Ordinance. • Areas identified within a 100 -year interval floodplain as identified by an applicant floodplain study. Management of floodplains in Roanoke County shall be in accordance with the requirements published in the County of Roanoke Zoning Ordinance. Under no conditions, shall the land disturbance activity adversely affect the capacity of channels, floodways, ditches, or any drainage facility or system. The lowest floor elevation of any new residential structure, as defined in the County of Roanoke Zoning Ordinance Section 30-28, shall be at least 2 feet above the base flood elevation. The lowest floor elevation of any new non-residential structure shall be at least 1 foot above the base flood elevation unless the structure is floodproofed. The elevation of the lowest floor shall be certified by a ",.,.'Registered *ufv-& e Surveyor or professional engiixeer-Engineer on an Elevation Certificate after the lowest floor is installed. Grading and cut and fill operations within the 100 -year flood plain are discouraged and must be approved by the County of Roanoke. Activity within the floodplain must also be coordinated with other regulatory requirements and agencies. These may include erosion and sediment control, stream buffer protection, FEMA, VMRC, U.S. Army Corps of Engineers, Virginia DEQ, and others. COUNTY OF ROANOKE 9 44X/x/16 12-3 ENVIRONMENTALLY SENSITIVE AREAS ENVIRONMENTALLY SENSITIVE AREAS CHAPTER 12 Construction of stormwater management impoundment structures within a floodplain shall be avoided to the extent possible. Where this is unavoidable, all stormwater management facility construction shall be in compliance with all applicable regulations under the National Flood Insurance Program, 44 CFR Part 59, and in accordance with the County of Roanoke Zoning Ordinance. The County does not have the authority to alter or modify the flood limits and/or elevations established by FEMA. Should an applicant flood study indicate any alteration in FEMA's limits and/or elevations, then the applicant must contact FEMA and obtain a map revision. 12.2.1 Applicant Flood Study Requirements A flood study, prepared by a Professional Engineer, must be prepared and submitted, by the applicant, for all areas where the drainage area is 100 acres or greater, and there are no detailed flood profiles or elevations from a FEMA Flood Insurance Study. There are two levels of studies. A detail study is required, if any development is proposed within the floodplain. Development includes grading and road crossings. A limited detail study is acceptable, if no development is proposed within the floodplain and the purpose of the study is to avoid the floodplain. A detail study involves a rigorous detailed hydrologic and hydraulic study of a flooding source reach. The typical riverine detail study includes the following minimum steps: • Field survey of stream and floodplain cross-sections • Field survey of all hydraulic structure crossings. • Collection of historical high water mark elevations and model calibration/verification, if data is available. • Detailed hydrologic & hydraulic modeling/computations • Establishment of the FEMA regulatory Floodway • Other tasks meeting all FEMA Guidelines and Specifications for Flood Hazard Mapping Partners A limited detail study may be performed when development is to occur adjacent to, but not in the existing floodplain. In most limited detail modeling, local regional regression equations along with a HEC -RAS hydraulic model will be developed. The major difference between the HEC -RAS models for the limited detail study and the detail study will be the amount of field survey information collected in the field and used to create the model and the amount of time spent on calibration to historical flood elevations. The limited detail models typically include no field survey data, and floodways are typically not computed. The COUNTY OF ROANOKE g414 x/x/16 12-4 ENVIRONMENTALLY SENSITIVE AREAS ENVIRONMENTALLY SENSITIVE AREAS CHAPTER 12 methods for limited detail study are further outlined in the FEMA Guidelines and Specifications for Flood Hazard Mapping Partners In addition, the following information and items are required when an applicant flood study is submitted to Roanoke County for review: • The flood study shall be based on the ultimate land use conditions as - - Formatted: Font: Bold published in the most recent Comprehensive Plan for upstream areas. Structure locations shall be based on the ultimate build out data. • The flood study shall be prepared by a registered Professional Engineer licensed to practice engineering in Virginia, sealed, signed, and dated. • Assuming that sedimentation or scour may occur during the storm event is not acceptable. • The flood study shall compare pre- and post -development conditions to verify that the proposed development will not increase the 100 year flood elevation more than 1 foot at any point. • The flood study shall consider backwater conditions, local obstructions and, where required by the County of Roanoke Department of Community Development, the partial or complete failure of any enclosed drainage system. Consideration must be given to the overflow path, to ensure that no structures will flood in the event of system failure. • The flood study shall analyze the 100 -year flood path for all new development. • A digital version of the 100 -year flood limits and cross sections must be sepplied-pmL:ided to the County. The study and supporting data will become .public information. The site plan digital file shall be in ACAD format and tied to the correct State Plane Coordinate. • Cross sections from the study must be indicated on the site plans submitted as a part of the development review package. 12.2.2 Floodplain Delineation The limits of floodplain floodways shall be staked and flagged in the field prior to any land disturbance activities and they shall remain undisturbed during construction. After the completion of construction, the limits of floodplain COUNTY OF ROANOKE 9 44X/x/16 12-5 ENVIRONMENTALLY SENSITIVE AREAS ENVIRONMENTALLY SENSITIVE AREAS CHAPTER 12 floodways shall be checked to verify that no unauthorized filling has taken place in the floodway. Place floodplain limits and floodways on the final plats submitted for each property. All subdivision plats and site plans located within the floodplain in whole or in part shall include base flood elevation data. 12.3 Steep Slopes Special precautions and guidelines are required for development in areas having steep slopes, defined as thirty-three and one third percent (33.3%) or greater. These precautions and guidelines address the increased potential for soil erosion, sedimentation, water pollution and septic disposal problems associated with the development of areas with significant topographical relief. Unrestricted development of steep slopes may result in: • Rapid and/or large-scale movement of soil and rock; • Rapid and excessive stormwater run-off, • Deposition of eroded material leading to siltation of natural and man-made bodies of water; • Loss of aesthetic resource; and • Greater travel distance of septic effluent in the event of septic system failure. 12.3.1 Development Restrictions Land -disturbing activities on steep slopes are regulated by Chapter 8.1 of the County Code, "Erosion and Sediment Control and Steep Slope Development Ordinance of the County of Roanoke, Virginia." If the grade of a site is greater than 33.3%, refer to the International Building Code for steep slope development requirements. 12.3.2 Design Standards No land disturbance of steep slopes may occur without a geotechnical study that concludes that the land disturbance will result in a stable finished slope. For the requirements of a geotechnical study, see County of Roanoke Erosion and Sediment Control and Steep Slope Ordinance. COUNTY OF ROANOKE 9 44X/x/16- 12-6 ENVIRONMENTALLY SENSITIVE AREAS ENVIRONMENTALLY SENSITIVE AREAS CHAPTER 12 Land disturbance of steep slopes require the preparation and submittal to the County of as -built plans showing that the finished geometry is in substantial conformity with the approved site plan. Site grading and measures required to control stormwater runoff shall collect and carry storm drainage away from the steep slope to the extent possible. If concentrated runoff is to be discharged in areas of steep slopes, adequate protection must be installed to prevent channel erosion and energy dissipation shall be used at the base of the steep slope to prevent erosion where the flow transitions to a shallower slope. The use of a closed conduit storm drain should be considered in accordance with Chapter 7. 12.4 Stream Buffers Stream buffers are established to provide a naturally vegetated strip of land adjacent to stream. This buffer protects the stream from encroachment by development, preserves the water, recreational, and environmental resources, protects the floodplain and floodway, retards runoff, and helps improve the water quality of stream by preventing erosion and filtering non -point source pollution from runoff. The establishment of stream buffers as a water quality measure is encouraged by the County of Roanoke. Requirements for stream buffers shall be in accordance with Section 30-75 of the County of Roanoke Zoning Ordinance- Roanoke River Conservation and Overlay District. Additionally, the development must meet the required stream setbacks as outlined in Section 30-75-5. 12.5 Critical Erosion Areas Critical erosion areas, if cleared of vegetation and exposed to the elements of nature, may experience significant erosion and sedimentation problems, including a significant loss of topsoil. These soils tend to be located on hillsides and areas with steep slopes, and adjacent to river valleys and tributaries. Critical erosion areas include 'we s4 ea'egafie : • The erosion hazard is critical if the slope length exceeds the following criteria: 0-7% slope > 300 feet COUNTY OF ROANOKE 9 44X/x/16 12-7 ENVIRONMENTALLY SENSITIVE AREAS ENVIRONMENTALLY SENSITIVE AREAS CHAPTER 12 7-15% slope > 150 feet >15% slope > 75 feet Critical erosion areas shall be indicated on the Erosion and Sediment Control Plan. To the— - - jFormatted: indent: Left: o.s", First line: o" extent feasible, disturbance of critical erosion areas shall be avoided or minimized. Where critical erosion areas are disturbed, their protection and stabilization shall specifically be addressed by the Erosion and Sediment Control Plan and the Stormwater Management Plan. 12.6 Karst Geology Developers and Designers are cautioned that construction in karst geology requires special care and study; and that they are responsible to ensure that all appropriate investigations are performed by licensed geotechnical engineers or geologists to ensure long-term soil stability for proposed buildings and site improvements. Although proper study of site conditions is the responsibility of the Developer and Designer, Roanoke County may, at its discretion, require a geotechnical investigation, prepared by a licensed geotechnical engineer or geologist, on a case by case basis. COUNTY OF ROANOKE 9 44X/x/16 12-8 ENVIRONMENTALLY SENSITIVE AREAS ENVIRONMENTALLY SENSITIVE AREAS CHAPTER 12 Karst is an underlying geology which is common in Roanoke County where the underlying rock is predominantly soluble limestone or dolomite creating caves, crevices, and other cavities in the rock. Stormwater may infiltrate to the karst geologic rock and quickly drain through the open cavities. In addition to providing a quick transport mechanism for potential stormwater pollutants, this may create quick erosion of the limestone, potentially causing sinkholes or other surface sloughing. Identification of karst geology shall be based on local geology and soils maps, aerial photography, and site visits by a person familiar with karst geology. Karst areas present problems with conventional hydrologic stormwater models, creating poor representation of runoff rates as most models do not have allowances for losses through sinkholes, crevices, or caves.

These sites must also meet DEQ6R VSMP and DEQ VPDES permit requirements, where applicable. 12.7.2 Golf Course Development Golf courses, while maintaining impervious area and natural buffers allow for the introduction of nutrients into stormwater through fertilizers and chemicals into stormwater through the use of pesticides and herbicides. Design of golf courses, public or private, should meet the following performance standards: 1. Managed turf should be reduced by including areas of rough devoted to native plants, natural environments, and wildlife habitat enhancement; 2. An Integrated Pest Management and nutrient management plan should be prepared and followed; 3. Native or naturalized landscaping should be used to the extent possible; 4. Natural vegetation and trees along streams should be retained to the extend possible; 5. Stream crossings should be minimized; 6.

Possible problems which may develop without proper maintenance include: • Stormwater structures may become clogged with debris reducing flow capacity which may cause upstream flooding; • Stormwater storage facilities may fill with sediment or debris reducing storage capacity and diminishing the ability of the facility to lower storm flows which may result in flooding downstream; • BMPs may not remove pollutants at the design levels required to meet the water quality requirements. If vegetation is not periodically cut and removed, it may release nutrients back into the environment, negating their water quality benefit. Stormwater management facilities include detention and retention basins, bioretention, grassed swales, and other BMPs that are intended to control stormwater runoff and change the characteristics of that runoff including, but not limited to, the quantity and quality, the period of release or the velocity of flow. Stormwater management facilities also include pipes and open channels, where the pipes and open channels are integral parts of the BMP (e.g. the pipes in a detention basin that convey flow from the outlet structure through an embankment to the discharge), and where the pipes and open channels are being used as BMPs to store or treat stormwater. Pipes (culverts and storm drains) and open channels that do not store or treat stormwater and are not an integral part of a BMP are storm drainage systems and not stormwater management facilities. Maintenance of stormwater management facilities are addressed in this Chapter. Maintenance of culverts, storm drains, and open channels that are not stormwater management facilities are addressed in their respective chanters. The maintenance guidance provided in this chapter is the routine maintenance that should be anticipated for typical nonproprietary BMPs; however, it is not meant to be all-inclusive. It is the applicant's responsibility to provide a project specific maintenance plan and schedule as part of the maintenance agreement. Information on BMP maintenance may also be found in the y^ 91.444 u,.raw221 v and toe Bean Clear-:n,.i.,.use website- ra f em *' Manufacturer's literature. 14.1 Responsibility for Maintenance COUNTY OF ROANOKE q 1 X11/16 14-1 MAINTENANCE MAINTENANCE OF STORMWATER MANAGEMENT FACILITIES CHAPTER 14 Maintenance of stormwater management facilities is the responsibility of the permittee during construction until all work is completed, including final clean up and site stabilization, to the satisfaction of the County. At the completion of construction, maintenance of stormwater management facilities becomes the responsible party or land owner's responsibility in accordance with the executed Maintenance Agreement. The County is not responsible for maintaining private stormwater management facilities. 14.2 Maintenance Agreements A legally binding maintenance agreement specifying the parties responsible for the proper maintenance of all stormwater management facilities shall be secured prior to issuance of any permits for land disturbance activities. Responsibility for the operation and maintenance of stormwater management facilities, after the completion of construction, shall remain with the responsible party or property owner and shall legally pass to any successor or owner. The maintenance agreement shall include a project specific appendix that lists all stormwater management facilities present on the property; the minimum frequency of inspections and maintenance, and the routine maintenance that is to be performed for each stormwater management facility. The project specific appendix to the maintenance agreement is to be prepared by the applicant and submitted to the County with the Stormwater Management Plan for review. The information contained within the VA SWM Handbook-aH4. the VA BMP Clearinghouse, and Manufacturer literature shall be used, by the applicant, as a guide in preparing the project specific appendix to the maintenance agreement; however, the maintenance requirements shall be written to be specific to the project. When landscaping is a component of the stormwater management facility, a project specific maintenance schedule for the landscaping shall be provided that is reflective of the plant species that are used. The landscaping maintenance schedule shall contain guidance regarding methods, frequency, and time of year for landscape maintenance. The maintenance requirements shall stress the need to remove cut and remove vegetation from the BMP and the specific rate and method of fertilization, if any. A sample Maintenance Agreement is included on i ^ pe ff * ' ^ ^ .Roanoke County's website In addition, the applicant shall also establish easements for stormwater management facilities to grant the County the right of access for periodic inspections as described in Chapters 3 and 15. 14.3 Maintenance Program COUNTY OF ROANOKE 9 1 dx/1/16 14-2 MAINTENANCE MAINTENANCE OF STORMWATER MANAGEMENT FACILITIES CHAPTER 14 A consistent maintenance program is the best way to ensure that stormwater management facilities will continue to perform their necessary functions. The following components are common to many stormwater management facilities maintenance programs and shall be followed, where applicable. • regular Inspections - Formatted: Underline Scheduled inspections and additional inspections after major storm events are necessary to understand the condition of the stormwater management facility and discover deficiencies so that they may be corrected. • Vegetation Mana eg ment _ _ _ _ _ _ _ _ _ _- Formatted: Underline Most stormwater management facilities rely on vegetation to filter sediment from stormwater and to stabilize the ground surface of the BMP. 0 blowing- - Formatted: Underline Some stormwater management facilities may have no mow zones. Do not mow areas meant to stay natural. If mowing is allowed and desired, most grasses are hardiest if maintained as an upland meadow, with a blade height of 6 to 8 inches. If a shorter lawn is desired, additional lawn care will be needed to maintain turf health. Never cut grasses below a blade height of 4 inches. Grasses on embankments should be cut at least twice in the spring growing season, once in the summer, and twice in the fall growing season. Grass clippings should be collected, removed from the BMP, and disposed of properly. Ideally grass clippings should be composted and used as fertilizer or mulch in an upland area. Grass clippings must never be dumped into streams, open channels, storm drains, ponds, or stormwater management facilities as they will release nutrients as they decay which will flow into streams. o Lertilization - Formatted: Underline One of the primary purposes of most stormwater management facilities is to remove nutrients from stormwater; therefore, it is important to not over fertilize. Often fertilization is not required, especially if grass is maintained at a height of 6 to 8 inches. Only fertilize where necessary to maintain the health of vegetation and then take care to apply only the minimum that is required. o Fest and Weed Control - Formatted: Underline Avoid unnecessary pesticide and herbicide use. When absolutely required, use pesticides and herbicides in accordance with listed instructions and never allow spray to enter water as many of these chemicals are toxic to aquatic life in small concentrations. COUNTY OF ROANOKE 9 U dx/1/16 14-3 MAINTENANCE MAINTENANCE OF STORMWATER MANAGEMENT FACILITIES CHAPTER 14 ZZemoving Accumulated Sediment - - Formatted: Underline Vegetation surrounding stormwater management facilities is designed to trap sediment; therefore, vegetation is likely to become laden with sediment and bare spots may emerge. Bare spots should be raked, backfilled if needed, and covered with top soil. Disturbed areas should be reseeded and mulched. Excess material should be removed and may be used as a mulch or soil supplement. If the soil becomes compacted, then aeration may be necessary. _Unwanted Vegetation - I Formatted: Underline Embankments must be kept clear of woody plants (trees and bushes) because their roots could cause seepage or slope failure. Consistent mowing should control any unwanted vegetation. • _Slope, Embankment and Outlet Stabilization - Formatted: Underline Stable slopes and embankments are necessary to ensure that erosion does not add to water quality problems and that embankments do not breach. Maintaining a health stand of grasses on slopes and embankments and preventing the grown of deep rooted (trees and shrubs) vegetation on embankment areas are important. Animal burrows can also cause deterioration to embankments. Animal burrows should be filled in as soon as they are discovered. In some cases animal control may be needed to avoid excessive burrows. Outlet structures are particularly vulnerable to undercutting and erosion. A small problem, if it is not corrected, may quickly result in the need to replace an entire structure. Consult a professional engineer if sink holes, cracking, wet areas around the outlet pipe, pipe displacement, or rusting of the pipe is observed. • pebris and Litter Control Formatted: Underline Regular debris and litter removal will reduce the chance of clogging outlet structures, prevent damage to vegetated areas, reduce mosquito breeding habitats, improve site appearance, and reduce conditions for excessive algae growth. • Mechanical Components - Formatted: Underline Some stormwater management facilities have mechanical components including valves, sluice gates, anti -vortex devices, fence gates, locks, and access hatches that require periodic maintenance. • jnsect Control - Formatted: Underline The simplest way to control insects, particularly mosquitoes, is to avoid stagnant water. Most stormwater management facilities are designed to be dry within a short time after a rain event. If an insect problem develops in a detention basin or infiltration facility, then there is a maintenance issue that needs to be corrected. In stormwater management facilities, such as retention basins, that are designed to COUNTY OF ROANOKE 9 U dx/1/16 14-4 MAINTENANCE MAINTENANCE OF STORMWATER MANAGEMENT FACILITIES CHAPTER 14 have a permanent pool of water insects may be controlled by the prompt removal of floatable debris and perhaps by introducing and maintaining a fish population. • Access Road and Area Maintenance - Formatted: Underline Most stormwater management facilities are designed to be accessible by heavy machinery for maintenance and repairs. Access should be maintained by periodic removal of woody vegetation and upkeep of gravel areas. • Sediment and Pollutant Removal - Formatted: Underline The primary purpose of many stormwater management facilities is the removal of sediments and nutrients (which are often attached to sediments). Sediment will naturally accumulate in a stormwater management facilities and must be periodically removed. The frequency of sediment removal will vary widely depending on the stormwater management facility's type and character of the contributing watershed. Removed sediments and pollutants should be properly disposed of in an upland area. They should be stabilized with vegetation so that they are not eroded by rainfall. Once sediment is removed, the stormwater management facility should be quickly restabilized, usually with vegetation. If maintenance operations disturb more than 5,000 square feet, an erosion and sediment control permit will be required before commencing work. Sediment and pollutant removal will usually take heavy equipment and is beyond the capabilities of most property owners without the assistance of appropriate contractors. • Component Repair or Replacement --------------------------------- t Formatted: Underline J Eventually, like all infrastructure, stormwater management facilities' components will need to be repaired or replaced. Components may include inflow and outflow devices, trash racks and anti -vortex devices, valves, orifices, pipes, concrete structures, filter or infiltration media, earthworks such as embankments and side slopes Following completion of construction, routine maintenance shall be performed on stormwater management facilities as required and as specified in the Maintenance Agreement. If the County becomes aware that a stormwater management facility has not been adequately maintained, is not functioning properly, or has becomes a danger to public safety, public health, or the environment, the responsible party will be notified in writing. The responsible party shall then be required to address the deficiency issue within a reasonable time as identified in the written notice. Failure to address the deficiency issue may result in enforcement actions.

Emergency spillways normally consist of an open channel, usually trapezoidal in cross-section, which are constructed beside an embankment to carry stormwater discharge from the BMP that is too great to be carried by the principal spillway. Emergency spillways should only discharge stormwater very infrequently Emergency spillways are most often vegetated (grassed), but may be protected against erosion by rip rap or concrete.

Construction inspection ensures that the storm drainage systems and stormwater management facilities are constructed and installed in accordance with the approved Stormwater Management Plan. Once construction is complete, a final inspection will be conducted, and as -built documentation will be submitted to show that the constructed project meets the requirements of the approved Stormwater Management Plan. At this point, the responsibility for the operation and maintenance of the storm drainage systems and stormwater management facilities is transferred from the permittee to the property owner or responsible party. Where a project is constructed in phases, a final inspection shall be conducted of each completed phase as designated by the approved Stormwater Management Plan. The final inspection shall consist only of the phase being identified as complete. After construction is complete, the property owner or responsible party is required to conduct periodic inspections and maintenance of the stormwater management facilities. Property owner inspections and maintenance activities must be documented and maintained. The County of Roanoke will also conduct periodic post -construction compliance inspections of stormwater management facilities. 15.1 Construction Inspections Construction of storm drainage systems and stormwater management facilities shall comply with the approved final Stormwater Management Plan. Any changes to the approved design require a resubmittal to the County of Roanoke for approval. Inspections shall be performed by the permittee to ensure that construction conforms to the approved plans and specifications. Additional inspections will be performed by the County of Roanoke to confirm compliance. 15.1.1 Notifications to the County of Roanoke The permittee shall notify the County of Roanoke in advance of the start of construction and of the construction of critical components of a stormwater management facility. The following are examples of, but not limited to, critical components: • Before the start of construction; • Before installing a stormwater pond embankment; • Before installing pond outlet structures; COUNTY OF ROANOKE q4/44X/X/16 15-1 INSPECTION AND ENFORCEMENT INSPECTION AND ENFORCEMENT CHAPTER 15 • Before setting any concrete BMP structures, this does not include precast drop inlets or manholes; • Before installing energy dissipation structures and any outlet structure into a jurisdictional stream (perennial or intermittent flow); • Before installing any infiltration or bioretention BMP; or • Any other key BMP component as determined by the County of Roanoke 15.1.2 Periodic Inspections The permittee is responsible to perform adequate inspection of the construction activities to confirm that the site is in compliance with the Erosion and Sediment Control Ordinance requirements and that the construction of storm drainage systems and stormwater management facilities and BMPs are in conformance with the approved Stormwater Management Plan. Upon completion of construction, the permittee must provide certification from a licensed professional that the completed project is in accordance with the approved plans and specifications and must provide documentation of regular inspections sufficient to adequately support compliance. All permittee inspections shall be documented and written reports prepared that contain the following information: • The date and location of the permittee inspection; • Whether construction is in compliance with the approved Stormwater Management Plan; • Variations from the approved construction specifications; • Corrective actions that have been taken to correct previous violations; • Any violations that exist or corrective actions that have been completed; and • The name and signature of the person who performed the inspection. The County of Roanoke shall conduct periodic inspections during construction. During the County inspection, the permittee will provide all permittee inspections which have been conducted since the last County inspection for County observation. If the County finds any violations, the permittee shall be notified in writing of the nature of the violation and of the required corrective actions. In conjunction, the County may issue an order requiring that all or part of the land disturbing activities permitted on the site be stopped until the specified corrective measures have been taken. If the County of Roanoke determines that there is a repeated failure to comply with the approved plans and specifications, enforcement action may be taken. COUNTY OF ROANOKE q4/44X/X/16 15-2 INSPECTION AND ENFORCEMENT INSPECTION AND ENFORCEMENT CHAPTER 15 15.1.3 Final Inspection and As -Built Documentation Prior to final acceptance of the project the permittee is required to submit to the County of Roanoke as -built documentation, confirming that the storm drainage systems and stormwater management facilities and practices that have been constructed conform to the approved Stormwater Management Plan.

SUBMITTED BY: Jill Loope Director of Economic Development APPROVED BY: Thomas C. Gates County Administrator COUNTY ADMINISTRATOR'S COMMENTS: SUMMARY OF INFORMATION: In May of 2014, Roanoke County advertised a Request for Proposals for the sale and redevelopment of the former William Byrd building located in the Town of Vinton. The County received and accepted a proposal from Waukeshaw Development, Inc. to purchase and redevelop the facility into a mixed-use residential development. The proposed project includes the establishment of more than seventy (70) market rate apartments, consisting of one (1) and two (2) bedrooms, at a density determined through the zoning and design process. The projected investment for the redevelopment of the property is estimated at $9.2 million. The William Byrd building was constructed in 1930, and was used as an educational and vocational training facility from 1930-2010. The two (2) -story main building consists of 62,760 sq. ft. with an adjoining annex building consisting of 6,980 sq. ft. The property includes 6.494 acres, within walking distance to downtown Vinton. The property represents a unique opportunity for redevelopment as a mixed use residential and commercial project. To facilitate the redevelopment and historic preservation of the building, the County will submit an application to the Virginia Department of Historic Resources to pre -determine the facility's eligibility for inclusion in the National Register of Historic Places and the Virginia Landmarks Register. Page 1 of 2 To assist with the project, a three (3) -party performance agreement has been negotiated between Roanoke County, the Roanoke County Economic Development Authority and Waukeshaw Development, Inc. This agreement will assist the developerwith complex site and building re -development and infrastructure related costs, while providing new capital investment in Roanoke County and the Town of Vinton. The agreement allows for the sale of the property for ten dollars ($10) and an economic development grant in an amount equal to ten (10) years of new local tax revenue to be reimbursed to the company. New local tax revenue is defined as net new real estate taxes generated by the project. The total amount of the grant shall not exceed $1,000,000 over a ten (10) year period. If the development generates less than the estimated new local tax revenue, then the actual grant for that year shall be less. The ten (10) year period will commence on January 1, 2018. FISCAL IMPACT: Per the performance agreement, the grant will be calculated as a reimbursement based on new tax revenues generated by the project therefore the fiscal impact will be in the form of foregone revenue. ALTERNATIVES: 1) Adopt the contract of sale and development agreement and authorize the County Administrator, or any Assistant County Administrator, to execute the contract between the County of Roanoke, the Roanoke County Economic Development Authority and Waukeshaw Development, LLC. 2) Decline to adopt the contract STAFF RECOMMENDATION: Staff recommends approval of Alternative 1.

The proposed Hollins Road tower site has been strategically designed not only as to the geographical position but the height as well to allow multiple carriers to cover a specific area of Hollins Road (Route 501) and the population residing and conducting business, and to provide optimum in -building penetration as reflected on the attached propagation maps. The addition of the Hollins Road tower site will provide for consistent and ubiquitous coverage from the Verizon tower site to the north (Cloverdale) and the Verizon tower site to the south (Plantation Road). Without the Hollins Road tower site the in - building wireless coverage will remain weak and outdoor coverage inconsistent. The wireless carriers cannot successfully compete with wireline internet and security system providers if coverage is not improved. Once this tower is constructed there is no reason why another broadcast tower would be needed in this area for many years to come, thus, reducing the number of broadcast towers in the county. Please explain how this project conforms to the general guidelines and policies contained in the Roanoke County Community Plan This tower and the facilities have been positioned on the property to have the least visual impact as possible. The facilities are located behind the existing building with the front view blocked by the building and mature foliage and trees surrounding the other three sides. We purposely kept the compound design to a minimum (2500 sq. ft. versus the normal compound size of 10,000 sq. ft.) and the area will be protected by a 6 ft. chain link fence with a locked gate. We will remove only the trees and foliage necessary to construct the compound area. Please describe the impact(s) of the request on the property itself, the adjoining properties, and the surrounding area, as well as the impacts on public services and facilities, including water/sewer, roads, schools, parks/recreation and fire and rescue. We do not believe there will be an adverse impact on the property itself or to the adjoining properties. The leased property is currently being used as industrial space which is consist with a broadcast tower. The property to the north is the Roanoke County Fleet Maintenance facility which is used to maintain the County's vehicles. It our understanding a tower was approved on the maintenance facility property several years ago for emergency and county service purposes but it was never built. We met with the county two years ago to discuss the possibility of reviving that project and the negotiations stalled. The property to the immediate east of the proposed location is the Norfolk Southern Corporation railroad property. The property to the south and west of the leased property across Hollins Road (Route 501) is also industrial property. This tower site should have minimal to no adverse impact on public services as we plan to bring electric and telco services underground in PVC conduit. There should be adequate ingress and egress in the event fire or rescue services are required. CONCEPT PLAN CHECKLIST A concept plan of the proposed project must be submitted with the application. The concept plan shall graphically depict the land use change, development or variance that is to be considered. Further, the plan shall address any potential land use or design issues arising from the request. In such cases involving rezonings, the applicant may proffer conditions to limit the future use and development of the property and by so doing, correct any deficiencies that may not be manageable by County permitting regulations. The concept plan should not be confused with the site plan or plot plan that is required prior to the issuance of a building permit. Site plan and building permit procedures ensure compliance with State and County development regulations and may require changes to the initial concept plan. Unless limiting conditions ate proffered and accepted in a rezoning or imposed on a special use permit or variance, the concept plan may be altered to the extent permitted by the zoning district and other regulations. A concept plan is required with all rezoning, special use permit, waiver, community plan (15.2-2232) review and variance applications. The plan should be prepared by a professional site planner. The level of detail may vary, depending on the nature of the request. The County Planning Division staff may exempt some of the items or suggest the addition of extra items, but the following are considered minimum: AL APPLICANTS a. Applicant name and name of development 7 b. Date, scale and north arrow V/ c. Lot size in acres or square feet and dimensions d.

I am making application on behalf of Apex Towers, LLC to construct a 154' self-supporting wireless communication tower on the property owned by William H. Mistele (Trustee) located at 5119 Hollins Road, Roanoke, VA 24018. This property is located in the tax district of Hollins on Parcel ID: 039.09-01-07.00-0000 in Roanoke County, and ownership is reported on a Deed of Correction dated March 30, 2006, recorded on March 30, 2006 in Instrument No. 200604785. This property is zoned I-2 High Density Industrial District which allows a Broadcasting Tower only by special use permit pursuant to section 30-19. This site (referred to as "Hollins Road") was designed by Apex Towers, LLC to assist Verizon Wireless and other wireless telecommunication carriers to provide additional coverage along State Route 601 and in -building coverage where it is very weak or non-existent. This tower site has specifically been designed to hand-off from the existing Plantation tower site to the southwest and carry wireless traffic to the northeast and handoff to the proposed Cloverdale tower site to northeast. Both sites (Hollins Road and Cloverdale) will allow Verizon to provide local citizens with high-speed wireless broadband internet service, giving local customers another choice for internet service.

We believe the construction of this 154' wireless communication facility is the best solution for Verizon and other wireless carriers (including cellular and personal communication services). Accordingly, we request that this application be presented and approved by the Roanoke County Planning Commission. Thank you for your consideration of this application and I look forward to presenting this application to the Planning Commission. In the meantime, if you require any additional information or have any questions, please do not hesitate to contact me. Re ectfull , avid B. McClure President Enclosures Apex Towers' Proposal for a Telecommunications Tower Proposal Apex Towers, LLC (Apex) is proposing a 154 foot (above ground including lightning rod) monopole tower on 4.58 acres of property owned by Mistele Declaration of Trust, William H. Mistele, Trustee located at 5119 Hollins Road in the northeastern portion of Roanoke County. Verizon has agreed to be the anchor tenant on this tower site. There is a need for additional coverage in this area to provide improved high-speed, high-quality wireless internet and communication services to Verizon's customers while they travel along State Route 601 and rural streets, in their homes and businesses in the designed coverage areas. This tower location has been designed to achieve the following objectives: • Improve the existing wireless network by supporting the latest wireless technologies and provide coverage to the following: Those living in nearby residential neighborhoods; Those travelling on Hollins Road and other connecting roads and streets in the designed area Future businesses and residents that may locate in the designed area • Provide hand-offs and complete the coverage of the following nearby Verizon towers (moving from the north to the south): Tinker Mountain --- Botetourt County - 1896 Tinker Top Road Proposed Cloverdale — County of Roanoke — 7014 Old Mountain Road Proposed Hollins Road -- County of Roanoke — 5119 Hollins Road Plantation Road — City of Roanoke - 320 Hershberger Road NW • Provide collocation opportunities for other wireless carriers to expand their networks. As indicated in a separate letter to the Planning Commission, Apex will build the Hollins Road tower site to accommodate no less than carriers. Compatibility with Comprehensive Plan The Roanoke County Land Use Plan designates the subject property as Principle Industrial. The Comprehensive Plan defines Principle Industrial as "areas where high technology industries and research and development firms are present or may develop ". The proposed tower will facilitate existing industries and promote new industries by providing high-speed, high-quality wireless service in the area, which is a necessity for "high technology industries". Chapter 3: Land Use Issues, Design Guidelines, Principle Industrial, Guideline #11, encourages "the siting of communication antennae and dishes on existing or new structures ". Carriers prefer to collocate on existing structures; however, there are no existing towers or structures within the search area that are a sufficient height or structural integrity to meet the coverage objective. Therefore, Apex is proposing a new tower on a parcel designated as Principle Industrial, which is consistent with Guideline #11. Chapter 3: Land Use Issues, Citizen Participation, Implementation Strategies #8, states that "Roanoke County should provide its citizens the opportunity to interface with each other and the capability to access all community services through the latest communications technologies ". The proposed tower will provide residents, businesses and travelers in the area access to the latest wireless technologies, which is consistent with this strategy. Without telecommunication and other comparable structures (commercial buildings, etc.), wireless carriers such as Verizon cannot provide high-quality wireless service. Zoning Ordinance requirements The subject property is zoned I-2, High Intensity Industrial District. In accordance with Article 3, Section 30-62-2(B)(4), Miscellaneous Uses, of the Roanoke County Zoning Ordinance, broadcasting towers are permitted subject to an approved special use permit. Article 4, Section 30-&7-2 of the Zoning Ordinance regulates broadcast towers. The applicable requirements listed in this section are as follows: Sec. 30-87-2. - Broadcasting Tower. (B) Applicability: 1. These standards shall apply to all new and replacement broadcasting towers within Roanoke County with the exception that new and replacement broadcasting towers and associated antenna not exceeding thirty (30) feet in height and located within any commercial or industrial zoning district shall be permitted by right provided: a. The proposed tower is a monopole type design; The proposed tower is a monopole design. b. The general area of the proposed tower is currently served by above ground utilities including electric power and telephone poles; and The general area of the tower is served by above ground utilities. c. All other use and design standards for the construction of the broadcasting tower and associated facilities are met. Apex will comply with all other use and design standards for the construction of the Hollins Road tower and associated facilities. 2. No modification to increase the height, size, type or location of any existing broadcasting tower or associated facilities, excluding antennas, shall be made unless such modification results in the full compliance of the broadcasting tower and facilities with all of the requirements of this ordinance. Not applicable; this is a new broadcast tower. 3. Antennas may be installed on any existing structure within the county, without the necessity of obtaining a special use permit, provided said antenna does not meet the definition of a broadcasting tower, does not increase the height of the existing structure more than ten (10) feet, and does not result in the structure and antenna exceeding the maximum structure height for that zoning district. Not applicable; this is a new broadcast tower. 4. These provisions shall not apply to any temporary broadcasting tower erected for the purpose of system design or testing provided the temporary broadcasting tower is erected for a period not to exceed twenty-one (21) days. In addition, in declared local emergency situations, the county administrator shall be authorized to allow the temporary installation of a broadcasting tower for the duration of the local emergency. A zoning 2 permit pursuant to section 30-9 of this ordinance shall be applied for and approved prior to erecting any temporary or emergency tower. Not applicable; this is a permanent broadcast tower. (C) Application requirements: 1. All potential applicants for broadcasting towers shall consult with county planning staff at least thirty (30) days prior to submitting an application for a proposed broadcasting tower. During this consultation the applicant shall present information to the staff on system objectives, proposed coverage areas, and alternative sites considered and rejected. The staff shall provide the potential applicant information on Roanoke County policies and standards for broadcasting towers, and shall discuss with the applicant possible alternatives to broadcasting tower construction. Apex conducted a pre -application meeting with the Planning Commission staff in 2014 and January 11, 2016. 2. In addition to the application requirements contained in section 30-19-2 of this ordinance, all applicants for broadcasting towers shall provide the following at the time of application: a. The location of all other proposed broadcasting tower sites considered and rejected, and the specific technical, legal or other reasons for the rejection. • While we looked at several locations outside and near the search Xing, there are no existing telecommunication towers or other structures that would meet the coverage objectives. Therefore, they were rejected. • The surrounding area is relatively rural and there are no existing structures tall enough to meet the coverage objectives. b. The location of all other possible collocation sites considered and rejected, and the specific technical, legal or other reasons for the rejection. Our anchor tenant (Verizon) is already collocated on all of the closest towers and there were no other existing structures within the search ring that are tall enough to meet the coverage objective. c. Accurate, to scale, photographic simulations showing the relationship of the proposed broadcasting tower and associated antenna to the surroundings. Photographic simulations shall also be prepared showing the relationship of any new or modified road, access or utility corridors constructed or modified to serve the proposed broadcasting tower site. The number of simulations and the perspectives from which they are prepared, shall be established with the staff at the consultation required in section C.1. above. Please see attached photo simulations. d. A computerized terrain analysis showing the visibility of the proposed broadcasting tower and antenna at the requested height and location. If new or modified road, access or utility corridors are proposed, the terrain analysis shall also show the visibility of these new or modified features. See attached computerized terrain analysis. e. Information on how the proposed site relates to the applicants existing communication system, including number of other sites within the Roanoke Valley, and the location of the antenna at each site. See attached propagation maps showing the relationship of the proposed Hollins Road tower site to other towers where Verizon has installed equipment and providing wireless services. All broadcasting tower applicants shall be required, at their expense to conduct an on-site "balloon" or comparable test prior to the planning commission and board of supervisors hearings on the special use permit. The purpose of this test shall be to demonstrate the potential visual impact of the proposed tower. The dates and periods of these tests shall be established with the applicant at the pre -application consultation. An on-site balloon test will be conducted from Ipm to Spm on the day the neighborhood meeting is scheduled. During the pre -application meeting we set a preliminary date during the first week of March and the staff will inform me of the exact date after the application is tiled. g. Written verification that all required submittals to the FAA as required by section 30-87-2(D)6 of this ordinance have been submitted. Apex is required by Federal law to comply with all FAA requirements when constructing a new tower. Apex has received the required approvals from. the FAA to construct this tower. 3. The applicant shall be responsible for all fees associated with the filing of the application including the reasonable cost of any independent analysis deemed necessary by the county to verify the need for the new broadcasting tower. The board of supervisors shall establish these fees, which shall be discussed with the applicant at the pre -application conference. These fees were discussed during the pre -application conference and a check is attached to cover these fees. (D) General standards: I . The maximum height of any proposed broadcasting tower and associated antenna shall be made as a condition of the special use permit, but in no case shall any broadcasting tower and antenna exceed one hundred ninety-nine (199) feet in height. Applicants shall request the lowest broadcasting tower and antenna height necessary to accomplish their specific communication objectives. The proposed Hollins Road tower is to be designed and built to a height of 154 feet (including a 4' lightning rod), which is the lowest height necessary to achieve Verizon's 21 coverage objective and allow other wireless carriers sufficient height to meet similar coverage objectives. 2. The setback for any proposed broadcasting tower shall, at a minimum, conform to the requirements for principal structures for the proposed zoning district. However, in no case shall the minimum setback from the base of the broadcasting tower to any residential structure on an adjoining lot be less than forty (40) percent of the height of the tower, measured from the closest structural member of the broadcasting tower (excluding guy lines). Guy lines shall be exempt from the minimum setback requirements in side and rear yards for the respective zoning district, but shall comply with the setback requirements for the front yard. Forty percent (40%) of the height of the proposed Hollins Road tower is 62'. There are no residential structures within several hundred feet of the proposed tower location. 3. The minimum setback from any property line abutting a road right-of-way for any other building or structure associated with a broadcasting tower shall be fifty (50) feet. Such buildings or structures shall be located a minimum of twenty-five (25) feet from any other property line. The closest property line is 75.9 feet from the Northern Southern Corporation (railroad) property line (i.e. rear property line) and over 200 feet from all other property lines. The position of the tower complies with these minimum requirements. 4. More than one (1) broadcasting tower shall be permitted on a lot provided all applicable requirements have been met including setback requirements. We are proposing to construct only one tower on this lot. 5. Broadcasting towers shall not be illuminated with any type of lighting apparatus, unless such lighting is a requirement of the FAA or FCC. When lighting is proposed to conform to federal requirement, the county shall contact the federal agency to verify the necessity of lighting, and to determine the minimal amount and type of lighting necessary to comply with federal guidelines. Security lighting, or a "down lighting" design may be installed on buildings and structures associated with a broadcasting tower. In no case shall any lighting violate section 30-94 of this ordinance. Please see attached FAA Aeronautical Study No. 2015 -AEA -3048 -OE issued on 06/1612015. The FAA conducted an aeronautical study and concluded that the proposed Hollins Road tower does not exceed obstruction standards and therefore, lighting is not necessary. 6. Any proposed broadcasting tower within two (2) miles from any general or commercial airport or located at a ground elevation at or above two thousand (2,000) feet, average mean sea level, shall be referred to the appropriate regional office of the FAA for review and comment prior to filing an application for a special use permit. Please see attached FAA Aeronautical Study No. 2015 -AEA -3048 -OE issued on 06/16/2015. The FAA conducted an aeronautical study and concluded that the proposed Hollins Road tower does not exceed obstruction standards and therefore, lighting is not necessary. As a matter of reference, the proposed Hollins Road tower site is 2.32 miles to the closest runway of Roanoke Regional Airport. 5 7. All broadcasting towers shall comply with any additional requirements established in the airport overlay district in section 30-72 of this ordinance, and the emergency communications overlay district in section 30-73. Apex agrees to comply with any additional requirements established in the airport overlay district in section 30-72 of this ordinance, and the emergency communications overlay district in section 30-73, if they become applicable in the future. 8. Any broadcasting tower approved shall be structurally designed to carry sufficient loading, and the site approved shall be sized to accommodate the additional equipment necessary for at least three (3) other vendors/providers of communications services in order to minimize the proliferation of new broadcasting towers in the vicinity of the requested site. In addition, by applying and being granted the special use permit, the applicant and the owner of the land agree to make the broadcasting tower and tower site available for additional leases within the structural capacity of the broadcasting tower and at reasonable costs adequate to recover the capital, operating and maintenance costs of the broadcasting tower location required for the additional capacity. The proposed monopole tower will be structurally designed and constructed to accommodate the equipment necessary for at least three (3) additional wireless communication providers and for Roanoke County to install equipment to provide emergency services, if needed. Apex Towers will provide tower space to Roanoke County for emergency services purposes at no charge. 9. A monopole broadcasting tower design is recommended. The board may approve an alternative broadcasting tower design if it finds that an alternative type of structure has less of a visual impact on the surrounding community and Roanoke County, and/or based upon accepted technical and engineering data a monopole design is not technically feasible. Cost shall not be a criteria for determining broadcasting tower design. As recommended by this section of the ordinance, we are proposing a monopole tower design for the Hollins Road site. 10. No broadcasting towers shall be permitted within the critical viewsheds of the Blue Ridge Parkway or Appalachian Trail as shown on any official map designating these viewsheds and pre -approved by the board of supervisors. In addition, no towers shall be proposed within any other designated area of local scenic, historical, ecological and cultural importance as designated and approved by the board of supervisors prior to the filing of a tower application. The proposed tower is not within the critical viewsheds of the Blue Ridge Parkway or Appalachian Trail. 11. By applying and being granted the special use permit, the applicant and the owner of the land agree to dismantle and remove the broadcasting tower and associated facilities from the site within ninety days of the broadcasting tower no longer being use for wireless communications. Dismantling and removal from the site shall only be required after notice by the County. If antennas on any approved tower are relocated to a lower elevation, the tower shall be shortened to the height of the highest antenna. A bond or similar performance guarantee may be required as part of the special use permit approval. Said guarantee will be in an amount sufficient to ensure removal of the tower and all associated facilities and the reclamation of the property and road, access and utility corridors to a condition that existed prior to tower construction. Apex agrees to dismantle and remove the broadcasting tower and associated facilities from the site within ninety days of the broadcasting tower no longer being used for wireless communications. Apex Towers has also made a similar commitment to the property owner to dismantle and remove the facilities. Please see Section L of the Option and Lease Agreement attached hereto. 12. All broadcasting tower structures and associated hardware, antennas, and facilities shall be a flat matted finish so as to reduce visibility and light reflection unless otherwise required by the FCC or FAA. The Hollins Road tower structure and associated hardware, antennas, and facilities will be designed and constructed with a flat matted finish so as to reduce visibility and light reflection. The FCC or FAA have not required any other finishes. 13. No business signs shall be allowed on the property identifying the name of, or services offered by, any business associated with the broadcasting tower. There will be no signage on the tower identifying the name of, or services offered by, any business associated with the broadcasting tower. (E) General review policies: All special use permit requests for new broadcasting towers, including the replacement or modification of existing broadcasting towers shall be reviewed by the staff, planning commission and board of supervisors on the basis of the following criteria: 1. The extent to which the broadcasting tower proposal conforms to the general special use permit criteria in section 30-19 of this ordinance, and the intent, application requirements, and general standards for broadcasting towers found in these provisions. The proposed Hollins Road tower will meet or exceed all special use permit criteria in section 30-19 of the ordinance, and the intent, application requirements, and general standards for broadcasting towers found in these provisions. 2. The demonstrated willingness of the applicant to evaluate collocation opportunities within the proposed communication service area, and the demonstrated history of the applicant choosing collocation sites within the Roanoke Valley. Apex is in the business of constructing and owning broadcast towers and leasing space on the towers to telecommunication providers. Apex does not own any FCC licenses and therefore, does not have any legal right to broadcast any wireless services. Accordingly, we have no need to collocate on sites in the Roanoke Valley. Our anchor tenant (Verizon) has agreed to collocate on our tower as documented in our agreement attached hereto and not build a separate tower because of the following: 7 1) Our tower meets its coverage objectives, 2) There are no existing towers or other suitable structures within the search ring that would meet the same coverage objectives, and 3) It is much cheaper for Verizon to collocate on a tower than incurring the entire costs to build a separate tower. 3. The base and top elevation of the proposed broadcasting tower relative to surrounding natural land forms. Notwithstanding any other provision of this section, broadcasting tower locations below surrounding ridge lines are preferred. The proposed Hollins Road tower will be located in a relatively flat area where it will be below the ridgeline to the east known as Read Mountain. Please see photo simulation #4 which shows the tower will be below the ridgeline. 4. Broadcasting tower locations already served by existing roads and utilities are preferred due to the potential detrimental environmental and visual impacts resulting from the construction of new road and utility corridors. As requested by the property owner, Apex will need to build a short access road to the lease area behind the existing building as reflected on the construction drawings attached hereto. The property owner made this specific request for the location of the short access road to preserve the property to the east of the existing building in the event he needs to expand the building to accommodate a current or future tenant. Apex and Verizon will use existing utilities and extend them to the lease area underground to minimize any detrimental environmental and visual impacts. 5. Within the needed service area, the availability of other existing structures that are, based upon independent analysis, of suitable height, design, and location for the needed antenna. There are no other suitable structures within the service area.. 6. The visibility of the broadcasting tower from the surrounding community and neighborhood compatibility of the tower as determined by the submitted computer simulations, terrain analysis and balloon or comparable test. The attached photo simulations and computerized terrain analysis were created to show the visibility of the proposed tower from the surrounding community and neighborhoods from four different viewpoints. We believe these documents show that the proposed tower will have limited visibility from surrounding streets and residences, and from two separate viewpoints, almost no visibility (Photos #3 and #4). 7. The degree to which the proposed tower location, site design and facilities including fencing, buildings and other ground mounted equipment and new or modified road, access or utility corridors are located, designed and constructed to be compatible with the neighborhood. Apex has planned the tower location and facilities to have limited visibility. Specifically, the tower site has been located and designed as follows to reduce visual effects: • Apex has selected a location behind the existing industrial building where existing mature trees will surround and screen the compound on the west and south sites, the 0 railroad tracks and right of way on the east side and the existing building to the north side; • Apex has chosen a location on the property on the edge of a wooded area where only a few trees will need to be removed for construction of the compound and access road and visibility from the ground level is almost not existent from all angles; • The proposed access road will run parallel with the railroad property which will not be visible from almost every angle; ,. r 1� 0 V W 0 0 Mead alunt 2C Letter -Revised Site Name: h,leatl &. t Irmt.

We actually expanded our search outside the search to make sure we had covered every potential structure. Most of the structures were rejected by Verizon because they were either outside the search ring or we could not obtain the necessary height to achieve the coverage objectives of Verizon and other wireless carriers. The closest potential site considered was the overhead transmission power site owned by AEP and currently used by AT&T. The site was rejected by Verizon because it is too far to the east of the search ring and the transmission structure is at capacity based on discussions with AT&T personnel. In 2014, AT&T upgraded the site with LTE equipment and they were limited to what could be installed due to the structural limitations of the existing transmission tower. The transmission tower would have to be replaced with a bigger, more structurally sound tower to handle a second carrier. Given that we would have to work around the power company equipment and schedules (which can consume more than a year), we have found these types of upgrades or modifications to be cost prohibitive. Therefore, we moved to a more central location that would meet the wireless objectives and be more cost efficient to construct and manage. 91 AntennaSearch - Search for Cell Towers, Cell Reception, Hidden Antennas and more.

Gates County Administrator COUNTY ADMINISTRATOR'S COMMENTS: SUMMARY OF INFORMATION: William Byrd High School was partially renovated in 2009 with the addition of fourteen (14) new classrooms and a new cafeteria to accommodate the increased enrollment of the school. During that time, the boys' and girls' locker rooms were not included in the scope of work for the project. Due to the very poor condition of the boys' and girls' locker rooms, Roanoke County Public Schools wishes to commission an architectural and engineering firm to redesign both areas to include fire suppression systems, new HVAC for proper ventilation, new lockers, plumbing fixtures, floors, finishes and tile walls. FISCAL IMPACT: Funding for the $10,000 will be provided from the William Byrd High School activity fund. STAFF RECOMMENDATION: Staff recommends approval of the first reading of this ordinance and scheduling of the second reading on April 12, 2016.

ITEM NO. AT A REGULAR MEETING OF THE BOARD OF SUPERVISORS OF ROANOKE COUNTY, VIRGINIA HELD AT THE ROANOKE COUNTY ADMINISTRATION CENTER MEETING DATE: March 22, 2016 AGENDA ITEM: Ordinance authorizing the granting of a greenway on property owned by the County of Roanoke (Tax map no. 60.11-04- 17.00.0000) for the purpose of completing the Glade Creek Greenway Project, Vinton Magisterial District SUBMITTED BY: Doug Blount Director of Parks, Recreation and Tourism Jill Loope Director of Economic Development APPROVED BY: Thomas C. Gates County Administrator COUNTY ADMINISTRATOR'S COMMENTS: SUMMARY OF INFORMATION: The 2007 Roanoke Valley Conceptual Greenway Plan identifies the Glade Creek Greenway as a future bicycle and pedestrian trail linking the Roanoke River Greenway to the Blue Ridge Parkway. The greenway will be an important recreational feature for the Town of Vinton and Roanoke County and will provide residents with connectivity to the existing Tinker Creek and Roanoke River Greenways, as well as Vinyard and Gearhart Parks. The proposed greenway will enhance neighborhoods and economic development opportunities for the Town of Vinton and Roanoke County. The greenway system has been strongly supported by citizens, businesses, civic organizations, and local governments. As such, the Roanoke Valley Greenway Commission made the Glade Creek Greenway its numberthree priority in the 2007 Update to the Roanoke Valley Conceptual Greenway Plan. Greenways were also strongly supported by Roanoke County citizens during development of the Department of Parks, Recreation and Tourism Comprehensive Parks Master Plan, completed in 2007. The residents of Roanoke County identified greenways as a "High Priority Need" for facilities and amenities desired in our community. Page 1 of 3 The proposed eighty -foot greenway easement is located on property owned by the Roanoke County Board of Supervisors, identified as Tax Parcel 60.11-04-17.00.0000, located in the Town of Vinton. The easement runs parallel to Glade Creek on the western portion of the property adjacent to Vale Avenue. The total easement area is 2.0596 acres (89,718 square feet) and extends 0.20 mile (approximately 1,100 feet). The subject property is currently for sale by Roanoke County. The property was previously owned by the Roanoke County School Board and formerly served as the Roanoke County Career Center and William Byrd High School. The property currently includes the bus garage and parking area for Roanoke County Schools. The proposed greenway will not impact these uses. Additionally, the property is used by the Roanoke County Parks, Recreation and Tourism Athletic Division for football, baseball, and soccer fields. The proposed greenway will have minimal impact to these uses; however, an athletic field and scoreboard may need to be relocated on the property. PROJECT STATUS: Design and engineering for Phase 1 of the Glade Creek Greenway is underway by the Town of Vinton. Phase 1 will extend from Tinker Creek at Virginia Avenue to Walnut Avenue along Glade and Tinker Creeks, following an existing sewer easement. The Town of Vinton has applied for funding for the Glade Creek Greenway Phase 2 through the FY17-18 Virginia Department of Transportation MAP-21/Transportation Alternatives Program which will extend from Walnut Avenue to Gus Nicks Boulevard (Project Number 16075). The total cost of the greenway is $526,210, and the donation of right-of-way from Roanoke County will serve as an in-kind match for the Town of Vinton. FISCAL IMPACT: The deed and plat were prepared internally by Roanoke County, in coordination with the Town of Vinton. Roanoke County Parks, Recreation and Tourism has incurred $500 to have the greenway easement recorded on a plat sealed by a licensed land surveyor. No additional fiscal impacts are anticipated. Design, permitting, construction, and maintenance of the greenway will be the Town of Vinton's responsibility. ALTERNATIVES: 1) Approve the first reading of the ordinance and schedule the second reading and public hearing for April 12, 2016. 2) Do not approve the ordinance.

ITEM NO. 1-1 AT A REGULAR MEETING OF THE BOARD OF SUPERVISORS OF ROANOKE COUNTY, VIRGINIA HELD AT THE ROANOKE COUNTY ADMINISTRATION CENTER MEETING DATE: March 22, 2016 AGENDA ITEM: Ordinance approving the sale of the 419 Library property to Heritage Roanoke, LLC and authorizing the execution of a contract of sale SUBMITTED BY: Jill Loope Director of Economic Development APPROVED BY: Thomas C. Gates County Administrator COUNTY ADMINISTRATOR'S COMMENTS: SUMMARY OF INFORMATION: This is the first reading of an ordinance authorizing the sale of the 419 Library property to Heritage Roanoke, LLC. Due to time constraints associated with Heritage Roanoke's current lease renewal and building renovation timeline, it is requested that the second reading be waived. The 419 Library was vacated by the County upon the completion of the new South County Library. The building and site were subsequently declared surplus, and at the Board of Supervisor's direction were made available for public acquisition. In December of 2015, Roanoke County entered into a contract with Poe & Cronk Real Estate Group to provide commercial brokerage and marketing services for the former 419 and Vinton libraries. The County received and accepted a proposal from Heritage Roanoke, LLC to purchase the 419 property and establish a corporate office at this location. American Healthcare, LLC, a for profit Corporation based in Roanoke County since 2010, will lease the property form Heritage Roanoke, LLC. The proposed operation will retain approximately fifty (50) employees in the County. Heritage Roanoke has indicated their desire to close on the property soon after the contract of sale is authorized by the Board of Supervisors so they can immediately begin renovating the facility. Staff is recommending that the Board waive second reading of this Page 1 of 2 ordinance to accommodate their construction and relocation timeline. Under Article V, Chapter 2, Section 2-123(h) of the Roanoke County Code, the Board may waive second reading upon a four-fifths vote. FISCAL IMPACT: As outlined in the contract of sale, Heritage Roanoke, LLC proposes to acquire the property from Roanoke County in "as is" condition at a purchase price of $1.54 million. Following a detailed staff analysis, it was concluded that the sale of the property would net an immediate financial advantage to the County, while avoiding significant up -front capital investments that would be required to maintain and lease the property. ALTERNATIVES: 1) Adopt the attached ordinance authorizing the sale of the 419 Library property to Heritage Roanoke, LLC and authorize the County Administrator, or any Assistant County Administrator, to execute a contract of sale, all upon form approved by the County Attorney. 2) Decline to adopt the attached ordinance. STAFF RECOMMENDATION: Staff recommends that the Board favorably consider the adoption of this ordinance and waive second reading. Page 2 of 2 AT A REGULAR MEETING OF THE BOARD OF SUPERVISORS OF ROANOKE COUNTY, VIRGINIA, HELD AT THE ROANOKE COUNTY ADMINISTRATION CENTER ON TUESDAY, MARCH 22, 2016 ORDINANCE APPROVING THE SALE OF THE 419 LIBRARY PROPERTY TO HERITAGE ROANOKE, LLC, AND AUTHORIZING THE EXECUTION OF A CONTRACT OF SALE WHEREAS, the Board of Supervisors owns property located at 3131 Electric Road consisting of two (2) parcels containing 2.526 acres and 0.93 acre previously used as the main headquarters for the County library system known as the "419 Library"; and WHEREAS, upon completion of the new South County Library, the 419 Library was vacated and made available for public acquisition; and WHEREAS, in July of 2014 the County advertised a Request for Proposals for either the sale or lease of the former 419 Library building; and WHEREAS, Heritage Roanoke, LLC, submitted an Offer to Purchase the property to establish a corporate office center for American Healthcare, Inc., which Offer the County accepted; and WHEREAS, a draft contract of sale has been prepared between the County and Heritage Roanoke, LLC, providing for the purchase of the property in "AS IS" condition at a total purchase price of $1.54 million, $1.49 million for the parcel containing 2.526 acres and $50,000 for the parcel containing 0.93 acre; and WHEREAS, this ordinance authorizes the conveyance of the former 419 Library located at 3131 Electric Road to Heritage Roanoke, LLC, upon the terms and conditions set out in the above-mentioned Contract; and Page 1 of 2 WHEREAS, Section 18.04 of the Roanoke County Charter directs the acquisition and conveyance of real estate interests be accomplished by ordinance; the first reading and public hearing for this ordinance was held on March 22, 2016. Due to time constraints the second reading was waived, upon a four-fifths (4/5th) vote of the Board pursuant to Article V, Chapter 2, Section 2-123(h) of the Roanoke County Code. NOW THEREFORE, BE IT ORDAINED by the Board of Supervisors of Roanoke County, Virginia, as follows: 1.

The County received notification in February of 2016 that it has received conditional approval for Part 2 of the application for inclusion in the National Register, which is the final step in a three-part process before the tax credits are issued. The first reading of this ordinance was held on March 8, 2016.

P-2 (a)(b)(c) AT A REGULAR MEETING OF THE BOARD OF SUPERVISORS OF ROANOKE COUNTY, VIRGINIA HELD AT THE ROANOKE COUNTY ADMINISTRATION CENTER MEETING DATE: March 22, 2016 AGENDA ITEM: Resolutions to set the following maximum tax rates for calendar year 2016: (a) Resolution to set the Real Estate maximum tax rate for calendar year 2016 to support the fiscal year 2016-2017 operating budget (b) Resolution to set the Personal Property maximum tax rate for calendar year 2016 to support the fiscal year 2016-2017 operating budget (c) Resolution to set the Machinery and Tools maximum tax rate for calendar year 2016 to support the fiscal year 2016-2017 operating budget SUBMITTED BY: Christopher Bever Director of the Office of Management and Budget APPROVED BY: Thomas C. Gates County Administrator COUNTY ADMINISTRATOR'S COMMENTS: SUMMARY OF INFORMATION: The approval of these resolutions represents an additional step in setting the tax rates as part of the fiscal year 2016-2017 operating budget development process. In prioryears, the tax rates were adopted by the Board of Supervisors without first setting maximum tax rates at a regularly scheduled Board of Supervisors' meeting prior to adoption of the tax rates. These resolutions will set maximum tax rates for Real Estate, Personal Property and Machinery and Tools taxes in advance of formal adoption of calendar year 2016 tax rates to support the fiscal year 2016-2017 operating budget. Formal adoption of the tax rates is scheduled on April 12, 2016, and will be preceded by a public hearing. Page 1 of 2 The fiscal year 2016-2017 proposed operating budget assumes the same tax rates as the fiscal year 2015-2016 operating budget. For reference, the adopted tax rates for calendar year 2015 to support the fiscal year 2015-2016 operating budget along with the value of a penny change on each of the tax rates is as follows: Tax Rate Description 2015 Calendar Year Tax Rate Value of a Penny on Tax Rate Real Estate Tax Rate $1.09 per $100 Assessed Value *$810,000 Personal Property Tax Rate including Business Personal $3.50 per $100 Assessed Value $87,000 Property Tax Machinery and Tools Tax $2.95 per $100 Assessed Value $8,500 *Reduction of a penny on Real Estate Tax rate would result in a $400, 000 reduction in revenue in current tax year. Reduction of revenue would only impact County operations. The adoption of these resolutions was preceded by a public hearing on March 22, 2016, to receive written and oral comments on setting the maximum tax rates for calendar year 2016 to support the fiscal year 2016-2017 operating budget. The public hearing on the maximum tax rates was advertised on March 8 and March 15, 2016, thereby satisfying State code requirements for public notice.

Page 1 of 1 Q-1 PETITIONER: Drew Patterson — Verizon Wireless CASE NUMBER: 10-10/2015 Board of Supervisors Consent 1St Reading Date: September 22, 2015 Planning Commission Hearing Date: January 2, 2016 Planning Commission Hearing Date (Continued) March 1, 2016 Board of Supervisors Hearing & 2nd Reading Date: March 22, 2012 A. REQUEST To obtain a special use permit for a broadcasting tower (cell tower) in a I- 1, Low Intensity Industrial District, on approximately 64.62 acre in size located at 7014 Old Mountain Road, Hollins Magisterial District. B. CITIZEN COMMENTS At the January public hearing, seven citizens spoke against this petition. Major concerns were the visibility of the proposed tower, the impact of the proposed tower on historic and environmental resources, adequate coverage issues, the effect of property values and the specific location on the overall parcel. Some comments addressed the existing businesses located at 7014 Old Mountain Road and the Roanoke County park (ball fields) in close proximately. At the March public hearing, two citizens spoke against the petition. Similar concerns were raised, including visibility and ownership. However, there were comments concerning the upcoming petition of a second broadcasting tower in the vicinity of this proposal, the amount of revenue that is generated from the tower and will lighting be required. C. SUMMARY OF COMMISSION DISCUSSION At the January public hearing: Rebecca James presented the staff report. Drew Patterson, the applicant and agent for Verizon Wireless and Lori Schweller, the attorney representing Verizon Wireless, presented a brief overview of the proposed use. Mr. Patterson and Ms. Schweller also spoke to the process and the ongoing review the application is currently in with various Federal agencies, including: the National Environmental Policy Act (NEPA) report, the Section 106 report, the Federal Aviation Administration (FAA) Air Space Study and the revised propagation maps run from the alternative AEP power mount location. There was also some discussion about the use of the AEP power mount as a potential co -location and additional data can be provided as to why that site is not feasible. Ms. Schweller also addressed some visibility concerns that were raised at the December 9th Community Meeting and spoke to the coverage needs and the type of services the proposed tower will provide. Maps were Q-1 provided, showing the distance from specific properties and the proposed tower, as well as the historic resources properties. George Condyles, Roanoke County's consultant for wireless communications, spoke in greater detail about the federal review process and provided a detailed background on the type of service the proposed tower will provide. Mr. Condyles also summarized his technical report, which is part of the application packet. He did recommend additional documentation prior to the Planning Commission making a motion. The Commissioners addressed the review period for the additional reports and documents. Proposed conditions were developed in conjunction with Mr. Condyles' technical report and information provided by the applicant. At the March public hearing: Lori Schweller presented a brief overview of what was requested at the January public hearing and what has since been submitted for review (see additional information in the attached memo). In addition, the same reports were submitted to George Condyles on February 8, 2016, who indicated he was in concurrence with all the submitted reports and suggested the Planning Commission recommend approval to the Board of Supervisors. The Commissioners addressed the concern of the upcoming petition of a new broadcasting tower and indicated this current petition is being evaluated on its own merit. D. CONDITIONS — as voted on at the March public hearing 1. Total height of the tower shall not exceed 158 feet. E. COMMISSION ACTION Mr. Bower made a motion to recommend approval of the petition with the one condition for the special use permit. The motion passed 4-0, with Mr. Marrano being absent. F. DISSENTING PERSPECTIVE None. G.

Per George Condyles' technical report, Roanoke County's telecommunication consultant with The Atlantic Group of Companies, Inc., the following was requested, before final approval is recommended to be granted: 1. Completion of The National Environmental Policy Act (NEPA) report. 2. Completion of the Section 1o6 report with comments from the Virginia Department of Historic Resources and the United States Department of Interior. 3. Completion of the Federal Aviation Administration (FAA) Air Space Study and meeting all recommendations from the FAA in regards to lighting requirements. 4. New propagation models run from the alternative AEP power mount location and written analysis of the AEP potential site. All of the above reports and documents were submitted to both Roanoke County and Mr. Condyles for review on February S, 2016. The reports, and supplemental documents are included as an attachment, as well as the revised technical review by Mr. Condyles. To summarize the above reports and documents: The NEPA report contains SHPO Section 16 submittal and concurrence, Virginia Department of Conservation and Recreation submittal and response, and the USFWS (United States Fish and Wildlife Service) submittal and response. P.O. 80X 29800 � ROANOKE, VIRGINIA 24018 - PHONE (540) 772-2080 , FAX (540) 776-7155 The FAA concluded the proposal and structure does not exceed obstruction standards and would not be a hazard to air navigation. In addition, markings and lighting are not required or necessary. Finally, the radio frequency (RF) justification has been submitted outlining why the AEP power mount transmission tower would not be feasible for co -location purposes. In summary, the primary reasons include location and distance of the AEP tower and adequate coverage issues. In addition to the written analysis of the AEP site, additional propagation maps were submitted, generally showing the difference between the proposed tower and the AEP tower to the south. Specifically, it shows areas that will not be covered at all by the AEP tower, but covered by the proposed tower and coverage areas that would be lost compared to the proposed tower. Drew Patterson and representatives from Verizon Wireless will be available at the March 1st meeting to provide an update on the requested reports and documents.

Area of Potential Effects You are required to provide two attachments regarding the Determination of Effect: Areas of Potential Effect and Mitigation of Effect (if applicable). Areas of Potential Effect Guidelines: a. Describe the APE for direct effects and explain how this APE was determined. The APE for direct effects is defined as the area of potential ground disturbance and any property, or any portion thereof that will be physically altered or destroyed by the undertaking. Therefore, the proposed 2,400 square feet of lease area and a 20 -foot proposed new access road are considered within the direct effects APE. b. Describe the APE for visual effects and explain how this APE was determined. The APE for visual effects is the geographic area in which the project has the potential to introduce visual elements that diminish or alter the setting, including the landscape, where the setting is a character -defining feature of a historic property that makes it eligible for listing on the National Register of Historic Places (NRHP). The presumed APE for visual effects for construction of new facilities is the area from which the tower will be visible. Due to the height of the proposed undertaking (158 feet), the presumed APE for visual effects for this project is a 0.5 -mile radius from the tower site. Applicant's Name: Verizon Wireless Project Name: Cloverdale Project Number: 141646028 FCC Form 620 Approved by OMB 3060-1039 See instructions for Public burden estimates NT SUBMISSION PACKET — FCC FORM 620 Attachment 5. Continued: Mitigation of Effect Guidelines In the case of where an Adverse Visual Effect or Adverse Direct Effect has been determined you must provide the following: a. Copies of any correspondence and summaries of any oral communication with the SHPO/THPO and any consulting parties. N/A b. Describe any alternatives that have been considered that might avoid, minimize, or mitigate any adverse effects. Explain the Applicant's conclusion regarding the feasibility of each alternative. N/A For each property identified as a Historic Property in the online a-106 form: a. Indicate whether the Applicant believes the proposed undertaking would have a) no effect; b) no adverse effect; or, c) an adverse effect. Explain how each such assessment was made. Provide supporting documentation where necessary. No historic properties were identified within the Direct Effects APE of this project during the survey dated September 17, 2015. There are two NRHP listed or eligible historic resources (Black Horse Tavern/Bellvue Hotel and Office Historic District and Bellegrove Farm) within the 0.5 mile Visual Effects APE of the project. Please see the Archaeological Survey Report provided as Attachment 7 and Architectural Resource Assessment provided as Attachment 8 for more details.

Tribal and NHO Involvement At an early stage in the planning process, the Nationwide Agreement requires the Applicant to gather information from appropriate Indian Tribes or Native Hawaiian Organizations ("NHOs") to assist in the identification of Historic Properties of religious and cultural significance to them. Describe measures taken to identify Indian tribes and NHOs that may attach religious and cultural significance to Historic Properties that may be affected by the construction within the Areas of Potential Effects ("APE") for direct and visual effects. If such Indian tribes or NHOs were identified, list them and provide a summary of contacts by either the FCC, the Applicant, or the Applicant's representative. Provide copies of relevant documents, including correspondence. If no such Indian tribes or NHOs were identified, please explain.

Continued C. Describe the techniques and the methodology, including any field survey, used to identify Historic Properties within the APE for direct effects.' If no archeological field survey was performed, provide a report substantiating that: i) the depth of previous disturbance exceeds the proposed construction depth (excluding footings and other anchoring mechanisms) by at least 2 feet; or, ii) geomorphological evidence indicates that cultural resource -bearing soils do not occur within the project area or may occur but at depths that exceed 2 feet below the proposed construction depth .2 Fieldwork was performed by Stantec on September 17, 2015. The Phase I archaeological field survey consisted of systematic surface evaluation and subsurface testing of the lease area and proposed access road. Shovel tests were excavated at a minimum of 50 - foot intervals. All shovel tests were at least 40 cm (1.3 feet) in diameter and were excavated to sterile subsoil. Soil from each shovel test was screened through %-inch hardware cloth, and representative soil profiles were recorded on standardized forms using Munsell color designators (Munsell Color 1994) and U. S. Department of Agriculture soil texture terminology. Archaeologists recorded a stratigraphic profile representative of each shovel test on a standardized shovel test form. The location of each shovel test pit was recorded on a survey map of the project area. The entire lease area and access road was subject to pedestrian survey. All shovel tests within the lease area, access road, and utility easement were negative. Soils from the shovel tests were both trowel sorted and screened through 0.25 -inch mesh. No artifacts and no archaeological sites were identified in the project area, and no further work is recommended. An Archaeological Survey Report dated September 29, 2015 is attached. Pursuant to Section VI.D.2.a. of the Nationwide Agreement, Applicants shall make a reasonable and good faith effort to identify above ground and archeological Historic Properties, including buildings, structures, and historic districts, that lie within the APE for direct effects. Such reasonable and good faith efforts may include a field survey where appropriate. 2 Under Section VI.D.2.d. of the Nationwide Agreement, an archeological field survey is required even if none of these conditions applies, if an Indian tribe or NHO provides evidence that supports a high probability of the presence of intact archeological Historic Properties within the APE for direct effects.

Geo -Technology Associates, Inc. 4376o Trade Center Place, Suite 110 Sterling, Virginia, 20166 RE: Archaeological Survey of the Proposed Cloverdale Telecommunications Tower in Roanoke, Virginia Dear Mr. Hendricks: The following report presents the results of an archaeological survey of the proposed Cloverdale telecommunications tower off Old Mountain Road in Roanoke, Virginia. The proposed project includes the installation of a 158 -foot monopole within a 2400 square foot lease area, and a 20 - foot proposed new access road (Figures 1-2). The lease area is located in an open grassy area. The access road is an existing gravel road (Photos 1-7). On September 17, 2015 Stantec Consulting Services Inc. (Stantec) conducted an archaeological survey of the proposed lease area. The archaeological survey was conducted with reference to state (Guidelines for Conducting Historic Resource Survey In Virginia [Virginia Department of Historic Resources {VDHR} 20111) and federal guidelines (Secretary of the Interior's Standards and Guidelines forArchaeology and Historic Preservation [United States Department of the Interior {USDI} 19831) for conducting archaeological investigations as well as in accordance with the Nationwide Programmatic Agreement Regarding the Section 1o6 National Historic Preservation Act Review Process (NPA) effective March 7, 2005. According to the NPA the Area of Potential Effects (APE) for direct effects is limited to the area of potential ground disturbance on the property. The Phase I archaeological survey, therefore, addressed the 2400 square foot lease area and the proposed 20400t wide access road. Guidelines set forth by the Eastern Shawnee Tribe of Oklahoma's Cultural Preservation Department entitled Consultation Procedures for Telecommunication Projects dated August 21, 2014 were referenced during this survey. This letter report contains a description of the project area's physical and environmental setting, a summary of field and research methods, survey results, and recommendations. Ellen M. Brady, MA, RPA, oversaw the project. Principal Investigator Aimee J. Leithoff, MA, RPA wrote this report and made the final recommendations. Archaeologist Jon Tucker, BA conducted the field work. Copies of all field notes, maps, correspondence, and historical research materials are on file at Stantec's office in Glen Allen, Virginia. tIL September 29, 2015 Page 2 of 16 Reference: Cloverdale CT Archaeology Report Stark M+ PIS kx%w end Ls �+�a br thr i1nN#dtY Ifs RNI Figure is Location of the Proposed Cloverdale Telecommunications Tower on Aerial Photography. oil j�{,'�, �• �. �4ndtlY�ILJ�'fViH dhl ll�'�IP �ifA c�k'Ytl� . _ r wI 4YYPw.PN�r.��\.F W Yliw Stark M+ PIS kx%w end Ls �+�a br thr i1nN#dtY Ifs RNI Figure is Location of the Proposed Cloverdale Telecommunications Tower on Aerial Photography. oil AJ September 29, 2015 Page 3 of 16 Reference: Cloverdale CT Archaeology Report Figure 2: Site Plan Cloverdale. a n J Figure 2: Site Plan Cloverdale.

The lease area is located in an open grassy area. The project area is located within the Blue Ridge physiographic province. In general, the Blue Ridge province consists of basement massif with Mesoproterozoic crystalline rock in its core and Late Neoproterozoic to Early Paleozoic cover rock on its flanks. The Blue Ridge province is allochthonous and has been thrust to the northwest over Paleozoic rocks of the Valley and Ridge province (The College of William and Mary Department of Geology 2011 and the Virginia Department of Environmental Quality [DEQ] n.d.). The lease area sits on Conococheague Formation which consists dominantly of limestone with significant dolostone and sandstone beds in lower part and locally in upper part. Limestone is a medium- to very -dark -gray, fine-grained, thin -bedded with wavy siliceous partings that weather out in relief (Rader and Evans 1993)• The project area is at an approximate elevation of 1250 feet above mean sea level (amsl) and is drained by Tinker Creek. Soil Morphology Loam dominates the vicinity of the lease area. The primary soil type in the immediate vicinity of the lease area is Tumbling loam which is located on a 7 to 15 % slope and are well drained soils (Soil Survey Staff). Soils within the lease area are depicted below (Table 1 and Figure 3). Table 1: Soil Map Unit Definitions for the Vicinity of the Project Area.

D tlL September 29, 2015 Page 10 of 16 Reference: Cloverdale CT Archaeology Report Research Design Stantec designed the Phase I archaeological survey to locate and identify all archaeological resources within the direct APE, defined as the 2400 square foot acre lease area and the 20 -foot wide proposed access road, and to evaluate the potential significance of any newly identified archaeological site(s). A cultural resource is gauged to be significant if it meets at least one of four criteria for eligibility for listing in the National Register of Historic Places (National Register): A. Associated with significant events in the broad patterns of national history, B. Associated with the lives of persons significant in our past, C. Representative of a type, period, or method of construction, or the work of a master, D. Capable of yielding important information about the past. Criterion D typically applies to archaeological sites. In order to be capable of yielding important information about the past, generally a site must possess artifacts, soil strata, structural remains, or other cultural features that make it possible to test historical hypotheses, corroborate and amplify currently available information, or reconstruct the sequence of the local archaeological record. To be considered significant, archaeological sites must demonstrate sufficient integrity to answer important research questions. These questions are developed in association with temporally, regionally, and thematically defined historic contexts or study units (United States Department of the Interior 1981). The background research for the survey included a thorough review of the VDHR archives and the Virginia Cultural Resources Information System (V -ORIS) for information on all recorded archaeological sites located within a 0.5 -mile radius of the subject property. Previous Investigations No previously identified archaeological sites are located within the Cloverdale lease area and access road or direct APE (Figure 4). The records of the VDHR list no previously identified archaeological resource within the 0.5 -mile radius of the project area. Field Methods The Phase I archaeological field survey consisted of systematic surface evaluation of the lease area. Shovel tests are typically excavated at a minimum of 5O400t intervals and measure at least 40 centimeters (1.3 feet) in diameter and were excavated to sterile subsoil. Soil from shovel tests when excavated are screened through 0.25 -inch hardware cloth, and representative soil profiles are recorded on standardized forms using Munsell color designators (Munsell Color 1994) and U. S. Department of Agriculture soil texture terminology.

The location of each shovel test pit was recorded on a survey map of the project area (Figure 5). Survey Results On September 17, 2015 Stantec conducted a Phase I archaeological survey of the Cloverdale telecommunications tower lease area and new access road, in Roanoke, Virginia. The proposed project includes the installation of a 158 -foot monopole within a 2400 square foot lease area, and a 20400t proposed new access road (Figure 5). The APE for direct effects considered for the Phase I survey was the 2400 square foot lease area and the new access road. The lease area is located in an open grassy area. The access road is an existing gravel road (Photos 1-7). The area is situated at about 1250 feet amsl. A total of 0.156 acres were investigated during the archaeological survey. A total of 3 hours was spent on the archaeological survey. Four shovel tests were excavated within the lease area (STP's 1-4) (Figure 5). Six shovel tests were excavated within the proposed new access road (STP's 5-10) (Figure 5). The entire lease area and access road was walked over and subject to pedestrian survey at 25 -foot intervals. One basic profile was noted in shovel testing which included clay and mottled clay subsoil on the surface. STP 4 contained a shallow layer of old plowzone over subsoil (Table 2). Soils from the shovel tests were both trowel sorted and screened through 0.25 -inch mesh. One the shovel test was positive for cultural material. Two small sherds of plain whiteware were recovered from STP 4. A single radial 25 -feet north of STP 4 was excavated and was negative. STP 3 is approximately 30 feet west and STP 6 is approximately 20 feet east on the edge of the access road as long with the rest of the shovel tests were negative for cultural material and no archaeological sites were identified in the project area. STP 4 is considered an isolated find (235-I171) as the rest of the lease area and access road retains no intact soils except in this small area near the corner as the rest of the lease area and access road is compact subsoil on the surface. Isolated finds by definition are not considered eligible for listing on the NRHP; no further work is recommended. 12 September 29, 2015 Page 13 of 16 Reference: Cloverdale CT Archaeology Report z— oLQ MOUNr �5�' N ROAD R a Figure 5: Detail of Cloverdale Installation, Depicting Shovel Tests in Lease Area and Access Road. 13 D a Figure 5: Detail of Cloverdale Installation, Depicting Shovel Tests in Lease Area and Access Road. 13 AJ September 29, 2015 Page 14 of 16 Reference: Cloverdale CT Archaeology Report Table 2.

The proposed project includes the installation of a 158 -foot monopole within a 2400 square foot lease area, and a 20 -foot proposed new access road. Based on the information gathered during background research, there are no previously -identified archaeological sites located within the Cloverdale lease area. The Phase I archaeological survey of the proposed telecommunications lease area did not identify any new archaeological resources within the APE for direct effects. An Isolated Find (235-IF1) was identified in the southeast corner of the lease area. Isolated Finds by definition are not eligible for listing on the NRHP. No further work is recommended.

Geo -Technology Associates, Inc. 43760 Trade Center Place, Suite 110 Sterling, Virginia, 20166 RE: Architectural Resources Assessment for the Cloverdale Cellular Site, Roanoke, Virginia Dear Mr. Hendricks: A review of the file material available at the Virginia Department of Historic Resources (VDHR) for architectural resources within the Area of Potential Effects (APE) for Indirect Effects for the proposed Verizon Wireless (Verizon) Cloverdale cellular site located at 7014 Old Mountain Road in Roanoke, Virginia was conducted prior to the field visit to the proposed site. The file review was conducted to determine if there were any previously recorded architectural resources within the APE for indirect effects and if any of these resources were potentially eligible, eligible, or listed on the National Register of Historic Places (NRHP) or as a National Historic Landmark (NHL) and would thus require a visual effects evaluation. As the proposed maximum height for the Cloverdale cellular monopole is 158 feet, the APE for the current Cloverdale project is determined to be a radius of 0.5 mile from the proposed tower location. The background file research, which involved a review of online digital records via the Virginia Cultural Resources Information System (V-CRIS), determined that two architectural resources met the criteria for consideration for indirect effects within the APE; the NRHP-listed Black Horse Tavern/Bellvue Hotel and Office Historic District (VDHR #080-5143) and the Bellegrove Farm (VDHR #080-0407) which has been determined to be eligible for listing on the NRHP by the DHR board. The three resources which are contained within the Black Horse Tavern/Bellvue Hotel and Office Historic District (VDHR #080-5143); the Black Horse Tavern (VDHR #080-0410), Bell Grove/Bellvue Hotel (VDHR #080-0408), and Bell Grove Office (VDHR #080-0409), have not been evaluated individually. Additionally, the Black Horse Tavern (VDHR #080-0410) was completely dismantled/destroyed due to poor condition in 2011. Three additional previously recorded architectural resources were located within the APE and which have not been evaluated individually for listing on the NRHP; a House, 7421 Shadwell Drive (VDHR #080-0411), House, 7126 Ould Drive (VDHR #080-0413), and Rowland Cemetery (VDHR #080-5441. Since the resources have not been evaluated for NRHP-eligibility they do not meet the criteria for consideration under the National Programmatic Agreement (NPA) for indirect effects. Table 1.

Brady, Senior Principal Investigator and Sandra DeChard, Architectural Historian. A site visit to the project area was conducted by Jonathan Tucker on September 17, 2015. The investigations were conducted with reference to state (Guidelines For Conducting Historic Resource Survey in Virginia 2011) and federal guidelines (Secretary of the Interior's Standards and Guidelines for Archaeology and Historic Preservation [United States Department of the Interior {USDI} 1983]) for conducting archaeological investigations as well as in accordance with the Nationwide Programmatic Agreement Regarding the Section 106 National Historic Preservation Act Review Process (NPA) effective March 7, 2005. Summary of Architectural Resources Considered for Visual Effects Assessment Two recorded architectural resource within the APE met the criteria for visual effects evaluation; the NRHP-listed Black Horse Tavern/Bellvue Hotel and Office Historic District (VDHR #080-5143) and the Bellegrove Farm (VDHR #080-0407) which has been determined to be eligible for listing on the NRHP by the DHR board (see Table 1). The three remaining resources have not been evaluated for NRHP eligibility and therefore do not meet the NPA criteria for consideration. Additionally, the three primary resources contained within the Black Horse Tavern/Bellvue Hotel and Office Historic District (VDHR #080-5143) have not been evaluated for individual listing on the NRHP. Bellegrove Farm (VDHR #080-0407) The house is a two-story, three -bay frame 1 -house situated on a stacked stone foundation, clad in weatherboard, and covered by a side gable roof covered in standing seam metal. Built in c. 1881, this house and the surrounding farm was owned and occupied by Julius Oliver (1825-1910) and is an unusual example of a rural property in Roanoke County owned by an African- American that included a substantial house and large amount of land in the late 19th century. Black Horse Tavern/ Bellvue Hotel and Office Historic District (VDHR #080-5143) Located across two parcels along Old Mountain Road, the Black Horse Tavern/ Bellvue Hotel and Office Historic District is comprised of three primary resources; the ca. 1782 log constructed Black Horse Tavern, c. 1854 Greek -Revival style brick Bellvue Hotel, and the c. 1840 Greek -Revival style temple -fronted brick office. Additional contributing structures were the c. 1900 Bellvue springhouse and a small c. 1930 frame shed clad in German siding associated with the tavern. Noncontributing structures contained within the district included a modern garage and swimming pool at Bellvue Hotel. The district was listed on the NRHP in 2002 under Criteria A and C for significance in commerce, transportation, architecture, and education. The architectural integrity of the district was based on the intact relationship of the three primary structures to the Old Carolina Road and to each other; however, the Black Horse Tavern was demolished in 2011 which may impact the integrity of the district. Visibility Evaluation During the field survey portion of the project an overall visual assessment was conducted to obtain a general view of the surrounding landscape. To facilitate the viewing of the cellular tower site from vantage points within the general vicinity, a helium -filled 3 -foot diameter weather balloon was flown at 120 and 199 feet and a flag at 150 feet, with 158 feet as the maximum height of the proposed cellular tower on the Cloverdale tower site. The balloon test served to simulate the height and location of the proposed cellular tower and provided a quantitative measure of visibility of the proposed installation. The purpose of the balloon flight was to determine if the proposed tower would be visible from the NRHP-listed Black Horse Tavern/ Bellvue Hotel and Office Historic District (VDHR # 080-5143) and Bellegrove Farm (VDHR #080- 0407) which are located within the defined 0.5 -mile APE for indirect effects. Bellegrove Farm (VDHR # 080-0407; Photo 1) is located within the north portion of the 0.5 -mile radius of the proposed telecommunications tower site APE. Photographs for the visual effects study were taken from the eastern edge of the resource property, along Old Mountain Road (Location 1) and Shadwell Drive (Location 3), looking toward the proposed tower site (Figure 3). The data gathered during the site visit indicated that the proposed tower at 120, 150, and 199 - feet will be visible from Bellegrove Farm (VDHR # 080-0407) from Location 1 (Photo 4). The proposed tower at 120, 150, and 199 -feet was not visible from Shadwell Drive (Location 3, Photo 7). Black Horse Tavern/ Bellvue Hotel and Office Historic District (VDHR #080-5143; Photos 2 and 3) is located within the northeastern portion of the 0.5 -mile radius of the proposed telecommunications tower site APE. Photographs for the visual effects study were taken from the western edge of the resource property along Old Mountain Road (Locations 4, 5, 7, and 9), from northeast of the Bellvue Hotel (Location 8), and from the front drive of the Bellvue Hotel just north of the Bellvue Office (Location 6), all looking toward the proposed tower site (Figure 3). The data gathered during the site visit indicated that the proposed tower at 120 feet will be visible from Black Horse Tavern/Bellvue Hotel and Office Historic District (VDHR # 080-5143) from Location 6 (Photo 10). The proposed tower at 120 and 150 feet will not be visible from the remaining points (Locations 4, 5, 7, 8, 9; Photos 8, 9, 12, 13, 14). The tower at 199 -feet would be visible from Locations 4 and 5 (Photos 7 and 8) therefore the proposed maximum height of the Cloverdale tower site was reduced to a maximum total height of 158 feet. Conclusions View shed analysis of the NRHP-listed Black Horse Tavern/ Bellvue Hotel and Office Historic District (VDHR # 080-5143) and the NRHP-eligible Bellegrove Farm (VDHR # 080-0407) conducted within the 0.5 -mile APE, determined that the proposed maximum height of 158 feet for the cellular tower would be visible from Photo Locations 1 and 6 for the resources under consideration. At Bellegrove Farm (VDHR # 080-0407), the tower at the maximum height of 158 feet was not visible from Photo Location 3, but was visible from Location 1. At the height of 158 feet, it is recommended that the proposed cellular tower will have a visual effect on Bellegrove Farm, but not an adverse visual effect. At Black Horse Tavern/ Bellvue Hotel and Office Historic District (VDHR # 080-5143), the tower at the maximum height of 158 feet was not visible from Photo Location 6, but was visible at 120 feet. The proposed tower at the maximum height of 158 feet was not visible from the remaining locations within the district (Locations 4, 5, 7, 8, and 9). At the height of 158 feet, it is recommended that the proposed cellular tower will have a visual effect but not an adverse visual effect on Black Horse Tavern/ Bellvue Hotel and Office Historic District. Overall it is recommended that the proposed Cloverdale telecommunications tower will have no adverse visual effect on the NRHP-listed resource and NRHP-eligible resource at 158 feet.

The approximate site address is 7014 Old Mountain Road, Roanoke, Virginia 24019. Geo - Technology Associates, Inc. (GTA) is performing an evaluation of the above referenced site under the National Environmental Policy Act (NEPA). A NEPA evaluation is required as part of the Federal Communications Commission (FCC) licensing process. A Project Review Form, a Site Location Map, a Topographic Map, a Lease Exhibitand Site Photographs are attached to this letter. The site is located at Latitude 37'20'36.0048" Longitude 79'55'2.1801" (Degrees Minutes Seconds). It is located approximately 1/4 mile southwest of the intersection of Shadwell Drive and Old Mountain Road (County Route 605), at the above referenced address, in the Roanoke area of Roanoke County, Virginia. GTA understands that Verizon Wireless proposes lease an approximate 2,400 square -foot sparsely wooded area to construct a fenced compound containing an approximate 158 -foot tall monopole tower and associated telecommunications equipment. In addition, GTA understands that Verizon Wireless proposes to establish an access and utility easement at the site. GTA is not aware of any critical habitats or officially designated wilderness areas on or in the immediate vicinity of the site. Natural Heritage Resources Database Species Search resulted in the identification of one listed bird species including the Loggerhead shrike (Lanus ludovncianus), two listed fish species including the Roanoke Logperch (Percirna red and Orangefin madtom (Noturus fflilberti), one listed butterfly species including the Appalachian grizzled skipper (PyrRus centaureae wyandot), and one listed plant species including the Smooth coneflower (Echinacea laewgata) occurring within the Roanoke County of Virginia. Considering the limited scope of the project and since no work is proposed in the waterbody, GTA anticipates no effect on the above referenced listed species. As part of the NEPA evaluation, GTA respectfully requests that you verify this and notify us in writing of your findings. A completed VDCR project review form is attached. Thank you for your attention to this matter, and we look forward to your response. Sincerely, GEO-TECHNOLOGY ASSOCIATES, INC.

Natural heritage resources are defined as the habitat of rare, threatened, or endangered plant and animal species, unique or exemplary natural communities, and significant geologic formations. This project is situated on karst-forming carbonate rock and can be characterized by sinkholes, caves, disappearing streams, and large springs. If such features are encountered during the project, please coordinate with Wil Orndorff (540-230-5960, Wil.Orndorfffr dcr.virginia.gov) to document and minimize adverse impacts. Discharge of runoff to sinkholes or sinking streams, filling of sinkholes, and alteration of cave entrances can lead to surface collapse, flooding, erosion and sedimentation, groundwater contamination, and degradation of subterranean habitat for natural heritage resources. If the project involves filling or "improvement" of sinkholes or cave openings, DCR would like detailed location information and copies of the design specifications. In cases where sinkhole improvement is for stormwater discharge, copies of VDOT Form EQ -120 will suffice. New "Karst Assessment Guidelines" developed by the Virginia Cave Board for land development can be found at http://www.der.virginia.gov/natural heritage/documents/karst assessment guidelines.pdf. In addition, according to the United States Fish and Wildlife Service (USFWS) Guidance dated September 14, 2000 "new construction of communication towers creates a potentially significant impact on migratory birds, especially some 350 species of night -migrating birds". "Communications towers are estimated to kill 4-5 million birds per year and some of these species affected are also protected under the Endangered Species Act and Bald and Golden Eagle Act" (USFWS, 2000). Therefore, DCR recommends voluntary implementation of USFWS interim guidelines for Communication Tower Siting, Construction, Operation, and Decommissioning (http://www.fws.gov/northeast/virginiafield/pdf/endspecies/Cell%20Towers/Cel I%2OGuidance. PDF). Under a Memorandum of Agreement established between the Virginia Department of Agriculture and Consumer Services (VDACS) and the DCR, DCR represents VDACS in comments regarding potential impacts on state - listed threatened and endangered plant and insect species. The current activity will not affect any documented state -listed plants or insects. There are no State Natural Area Preserves under DCR's jurisdiction in the project vicinity. 640 East Main Street, 24'x' Floor I Richmond, Virginia 23219 1 804-786-6124 State Parks + Soil and Water Canserilation • Outdoor Recreation Planning Natural Heritage • Dam Safety and Floodplain Management • Land Conservation New and updated information is continually added to Biotics. Please re -submit a completed order form and project map for an update on this natural heritage information if the scope of the project changes and/or six months has passed before it is utilized. A fee of $90.00 has been assessed for the service of providing this information. Please find enclosed an invoice for that amount. Please return one copy of the invoice along with your remittance made payable to the Treasurer of Virginia, Department of Conservation and Recreation, Division of Natural Heritage, 600 East Main Street, 20, Floor, Richmond, VA 23219. Payment is due within thirty days of the invoice date. Please note late payment may result in the suspension of project review service for future projects. The Virginia Department of Came and Inland Fisheries (VDGIF) maintains a database of wildlife locations, including threatened and endangered species, trout streams, and anadromous fish waters that may contain information not documented in this letter. Their database may be accessed from htlp://vafwis.org/fwis/ or contact Ernie Aschenbach at 804-367-2733 or 1;rnie.Aschenbach(ci�dait.virginia.pov. According to the information currently in our files, Tinker Creek, which has been designated by the VDGIF as a "Threatened and Endangered Species Water" for the Roanoke logperch is within 2 miles of the project area. Therefore, DCR recommends coordination with the U.S. Fish and Wildlife Service (USFWS) and Virginia's regulatory authority for the management and protection of this species, the VDGIF, to ensure compliance with protected species legislation. Should you have any questions or concerns, feel free to contact me at 804-371-2708. Thank you for the opportunity to comment on this project. Sincerely, �s r S.

(GTA) is performing an evaluation of the above referenced site under the National Environmental Policy Act (NEPA). A NEPA evaluation is required as part of the Federal Communications Commission (FCC) licensing process. A Site Location Map, Site Topographic Map, a Lease Exhibit, Site Photographs, USFWS Information, Planning and Conservation System (IPaC) Official Species Report, VaEagles Map, Species Conclusion Table, and Online Project Review Certification Letter are attached to this letter. The site is located at Latitude 37° 20' 36.0048" Longitude 79° 55'2.1801" (Degrees Minutes Seconds). It is located approximately 1/4 mile southwest of the intersection of Shadwell Drive and Old Mountain Road (County Route 605), at the above referenced address, in the Roanoke area of Roanoke County, Virginia. GTA understands that Verizon Wireless proposes lease an approximate 2,400 square -foot sparsely wooded area to construct a fenced compound containing an approximate 158 -foot tall monopole tower and associated telecommunications equipment. In addition, GTA understands that Verizon Wireless proposes to establish an access and utility easement at the site. GTA performed species search using USFWS Virginia On -Line Project Review Process, which concludes that one listed fish species including the Roanoke Logperch (Percina rex) and two listed mammalian species including the Indiana Bat (Myotis sodalis) and Northern Long-eared Bat (Myotis septentrionalis) might be present in the project area. There are no critical habitats or USFWS National Wildlife Refuges within the project area. No eagle nests were identified within 600 feet of buffer. A Species Conclusion Table is provided as an attachment to this letter for your review. 43760 Trade Center Place, Suite 110, Sterling, VA 20166 (703) 478-0055 Fax: (703) 478-0137 S Abingdon, MD S Laurel, MD S Frederick, MD t Waldorf, MD S Sterling, VA S Somerset, NJ S NYC Metro S New Castle, DE S Georgetown, DE b York, PA S Quakertown, PA S Towanda, PA S Malvern, OH S Williston, ND S Charlotte, NC Visit as on the web at www.gtwnff.com United States Fish and Wildlife Service Re: Cloverdale Cell Site December 9, 2015 Page 2 To minimize adverse impacts to migratory birds, the FCC incorporates recommendations from the USFWS Guidance on the Siting, Construction, Operation and Decommissioning of Communication Towers as possible. USFWS recommendations published in Interim Guidelines for Recommendations on Communication Tower Siting, Construction, Operation, and Decommissioning (2000) state the preferred tower height to decrease potential effects on migratory birds is less than 200 feet tall. The siting and design process for this project could not conform to all the USFWS recommendations. Therefore, it has included mitigating factors such as tower siting in minimally sensitive areas and limiting tower height to 158 feet. Considering the limited scope of the project and distance from the resources, GTA anticipates that the proposed proj ect will have no effect on the above referenced listed species. As a part of NEPA process, GTA is submitting this review package for the records of USFWS. Thank you for your attention to this matter.

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http://www.fws. gov/migratorybirds/CurrentBirdlssues/Hazards/towers/towers.htm; http://www.towerkill.com; and http://www.fws. gov/migratorybirds/CurrentBirdlssues/Hazards/towers/comtow.html. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

The following comments are provided under provisions of the Endangered Species Act of 1973 (16 U.S.C. 1531-1544, 87 Stat. 884), as amended, and Bald and Golden Eagle Protection Act (16 U.S.C. 668-668c, 54 Stat. 250) as amended. We have determined the project is not within 660 feet of a bald eagle (Haliaeetus leucocephalus) nest therefore, no Eagle Act permit is required and critical habitat will not be affected. We also concur with your detennination for Roanoke Logperch (Percina rex). You propose to remove less than 5 trees for this project. This site includes potential habitat for the federally listed threatened Northern long-eared bat (Myons septentrionalis) and Indiana Bat (Myotis sodalis). This project involves tree clearing and project modification(s) can be made that would avoid the likelihood of adverse effects to Northern long-eared bat and Indiana Bat. These modification(s) include: 1. Conduct emergent surveys for potential roost trees for the trees proposed for removal that are >3dbh. No more than 10 trees should be surveyed at a time. Emergent surveys for potential roost trees do not need to be conducted by a qualified bat surveyor. Follow the protocol for "Emergence Surveys for Potential Indiana Bat Roosts" in the most recent survey guidelines in Appendix E. If no bats are observed emerging from the roost. Per step 3a of the guidance, the tree should be felled immediately. Survey guidance can be found at: httn://www.fws.izov/northeast/viriziniafield/ndf/endsDecies/20151ndianaBatSummerSurvevGuidelinesO l Anri 12015.pdf .� . 2. Implement a time -of -year (TOY) restriction for no tree clearing from April 15 — September 15 of any year. If the proposed activity is modified as described above, through changes in project design or incorporation into permit conditions, the Service believes that the project would not likely adversely affect listed species and that further consultation pursuant to section 7 of the ESA is not necessary. If the above project modifications are not adopted, further consultation with the Service will be necessary pursuant to 50 CFR 402.13 and 402.14. Should project plans change or if additional information on the distribution of listed species or critical habitat becomes available, this determination may be reconsidered. If you have any questions, please contact me.

Therefore, this letter will serve to clarify the reasons why collocating on the AEI' tower will not result in VZW meeting its coverage objective. To begin, the following is the intended coverage objective for the proposed 158 foot monopole tower: • The high-density residential neighborhoods to the north and west; • Those travelling on Route 11, Hollins Road, Old Mountain Road and Shadwell Drive; • Those working in the nearby PCA Roanoke packaging and shipping plant and in numerous other commercial/industrial businesses located along Hollins Road; • Future industries that may develop on the large surrounding I-1, Low Intensity Industrial District, parcels. The following are the specific reasons that the AEP tower will not achieve this coverage objective: • The AEP tower is over 4,200 feet southeast of the proposed tower and isn't even located within the proposed search ring; it is within another search ring; • The AEP tower is not strategically located in the middle of the other VZW towers (Tinker Mountain, Bonsack and Plantation Road); therefore, it will not adequately assist with reducing capacity issues at these sites, which is a primary objective for this proposed facility. • The AEP tower would not provide adequate coverage to the neighborhoods to the north and west (compare the attached AEP propagation maps to those provided for the proposed site); • The AEP tower would provide very limited coverage to U.S. Route 11; Verizon Wireless 1831 Rady Court Richmond VA 23222 /`vedzonwireless The AEP tower would provide limited coverage to the PCA Roanoke packaging and shipping plant. The present location, height and design of the proposed tower are critical to the VZW network in this area as it will provide capacity and connecting service to existing adjoining sites. The coverage objective is primarily to the north therefore, shifting the site south 4,200 feet to the AEP tower will not adequately serve the intended target area. Given the lack of collocation opportunities in the area and limited industrial zoned property (eligible for communications towers), VZW respectfully requests that you approve the special use permit as submitted.

A Member of The Atlantic Group of Companies, Inc. ATC PROJECT #: 1100-10 Supplement #1 February 24, 2016 Aid -i yOF nOMPANIES .— EXECUTIVE SUMMARY Verizon Wireless (Verizon) has made application to the County for the issuance of a Special Use Permit to allow construction of a new 150 -ft monopole telecommunications support tower with 8' lightning rod at the address of 7014 Old Mountain Road, Roanoke, VA 24019. The property is owned by Bogar LLC located at 3330 Hollins Road, Roanoke, VA 24012. The Old Mountain Road property is Zoned 1-1 (Low Intensity Industrial District). The parcel is 64.62 acres and is referenced to Tax Map # 028.03-01-02.02-0000. The Bogar Facility is operating in an Industrial mode as per its Zoning Conditions. This original request as proposed in August of 2016 was to build a 199' monopole tower. This tower was reduced in height to a 150' AGL tower with an 8' lightning rod upon the review of the Virginia Department of Historical Resources State Historic Preservation Officer after a NEPA and Section 106 Historic Review was conducted. The Virginia Department of Historic Resources concluded on February 4, 2016 that there will be No Adverse Effect on the Historic Properties in the Area of Potential Effects. The Consultant originally recommended delaying final approval until the following documents and comments of the respective governmental organizations are received: 1. Completion of the NEPA Report with review comments from the Virginia Department of Environmental Quality. 2. Completion of Section 106 Report with comments from the Virginia Department of Historic Resources and the US Department of Interior. 3. Full FAA Air Space Study to Determine Lighting Requirement comments from the FAA. 4. Applicant should run Propagation models from the Alternative AEP Power mount location and provide written analysis of this potential site. The Applicant has completed the four (4) tasks above and the consultant has reviewed all of the new information. The Consultant believes that this site meets the technical requirements for a wireless communications facility and that Verizon has provided sufficient technical information to justify this site.

Atlantic Technology Consultants, Inc. Page 3 of 25 Mechanicsville, VA The proposed project Site Plans were prepared by the firm of Clark- Nexsen Engineers located at 133 L Street NW Suite 600, Washington DC 20005. Clark-Nexsen has provided accurate and precise Site Plans and Engineering advice to Verizon for many years. The diagrams, maps, drawings and specifications are a product of Mr. Justin Y. Yoon, P.E. who is the Project Site Engineer. The Site Plans submitted by Clark-Nexsen are professional and accurate and will be used in this report The proposed tower is a 150 -ft monopole tower with an 8 -ft lightning rod (for a total AGL of 158 -ft) placed within a 33'x 55' fenced compound. The site will be accessed from Old Mountain Road. (See Detailed Site Plan below) The center of the proposed tower is located at coordinates 370 20' 36.00" N and 790 55'02.18" W (NAD 83). Atlantic Technology Consultants, Inc. Page 4 of 25 Mechanicsville, VA 1.2 Topography The topography of this site is relatively flat. The ground elevation for the proposed tower is 1250' above sea level. The tower is proposed at 150' + an 8' Lightning Rod for an overall height of 158'. Combining the Ground elevation of 1250'+ 150' would give an Average Mean above Sea Level of 1400' AMSL. The Consultant has reviewed the information supplied and concurs to the height of the tower as conditions relative to the topography. Site placement is in an open area adjacent to the ball field in the southeast corner of the property. The access to the site is on an existing gravel road that is shielded by some pine and hardwood trees. The existing tree canopy is between 40 and 70 feet in most places. The site has a natural tree buffer around it and will cause very little land disturbance. The site (as for the topography) is well suited and will serve many residential and commercial facilities with advanced wireless broadband services. Atlantic Technology Consultants, Inc.

The Applicant has submitted a map and of existing tower sites within a 5 - mile radius of the proposed tower site. Verizon is essentially on all existing towers. This site is a fill-in site within the network. Another potential site is an AEP Power Line structure. There are several AEP Power line structures approximately 4,250 south of the proposed site. While these may not be ideal, the site below was evaluated as a potential solution as an Alternative Site. Atlantic Technology Consultants, Inc.

There were many discussions on existing and Alternative sites. Upon this discussion, Verizon prepared several Propagation maps that provided several scenarios. They are: 1. Co -location on the "potential AEP Power Structure". This site was evaluated by both Verizon and ATC. The Conclusion: Both parties agreed that the AEP site would be too far south thus removing approximately 20 to 25% of the coverage to the north-west which would be covering the existing homes in Roanoke County and nearby Botetourt County. Simply put, this site is out of position and the topography "shadows" the wireless signal from the directed coverage area. The Consultant concurs and this site is eliminated.

The new propagation maps include the planned site (which was just submitted for review January 15, 2016) of a site known as "Clearwater". This site is located approximately one (1) mile to the south in Industrial Zoning. While this Application is still under review, this tower will be the hand-off site and coverage center for the Verizon digital service to the south. This site is located in a topographic recessed area and this site is a part of the overall coverage plan for this corridor. The ground elevation difference between Cloverdale and the Clearwater is approximately 208' in loss of elevation to Clearwater. The existing and proposed coverage of Cloverdale and Clearwater complement each other and will provide for the expansion of the digital broadband service that Verizon has planned. Below is the written justification that Verizon has submitted. The consultant concurs. Atlantic Technology Consultants, Inc.

Therefore, this letter will serve to clarify the reasons why collocating on the AEP tower will not result in VZW meeting its coverage objective. To begin, the following is the intended coverage objective for the proposed 158 foot monopole tower: • The high-density residential neighborhoods to the north and west; • Those travelling on Route 11, Hollins Road, Old Mountain Road and Shadwell Drive; • Those working in the nearby PCA Roanoke packaging and shipping plant and in numerous other commercial/industrial businesses located along Hollins Road; • Future industries that may develop on the large surrounding I-1, Low Intensity Industrial District, parcels. The following are the specific reasons that the AEP tower will not achieve this coverage objective: • The AEP tower is over 4,200 feet southeast of the proposed tower and isn't even located within the proposed search ring; it is within another search ring; ■ The AEP tower is not strategically located in the middle of the other VZW towers (Tinker Mountain, Bonsack and PIantation Road); therefore, it will not adequately assist with reducing capacity issues at these sites, which is a primary objective for this proposed facility. • The AEP tower would not provide adequate coverage to the neighborhoods to the north and west (compare the attached AEP propagation maps to those provided for the proposed site); • The AEP tower would provide very limited coverage to U.S. Route 11; Atlantic Technology Consultants, Inc. Page 9 of 25 Mechanicsville, VA Verizon Wireless 1831 Rady Court Richmond VA 2322 2 �� vein �'��Yt�fi"P12SS The AEP tower would provide limited coverage to the PCA Roanoke packaging and shipping plant. The present location, height and design of the proposed tower are critical to the VZW network in this area as it will provide capacity and connecting service to existing adjoining sites. The coverage objective is primarily to the north therefore, shifting the site south 4,200 feet to the AEP tower will not adequately serve the intended target area. Given the lack of collocation opportunities in the area and limited industrial zoned property (eligible for communications towers), VZW respectfully requests that you approve the special use permit as submitted.

This tower will address the lack of 4-G/AWS coverage along Rt. 11 and east. Coverage Maps: Page 18. The "hole" in this area of the county is underserved by Verizon. Page 19. ATC's independent calculation of coverage from proposed Cloverdale 150' tower. Page 20. ATC's independent calculation of co -location on AEP Power Line. Page 21. Verizon's calculation of co -location on AEP Power Line @ 100' AGL. Page 22. Verizon's calculation of loss of coverage area @ approx.. 20 to 25%. Page 23. Verizon's Total Proposed coverage with Cloverdale @ 150' & Clearwater @ 145' AGL. Page 24. Verizon's Clearwater @ 145' AGL coverage Page 25. Verizon's Cloverdale @ 150' AGL coverage. The Atlantic Group Evaluation The Atlantic Group ran an independent RF analysis for this site. We see that there is a need to fill an RF data "Hole" in this area as defined by the Applicant's Radio Frequency Propagation models.(Page 18) ATC ran an independent analysis calculation (Page 19) and concurred with the Applicant's proposed 150' AGL tower. (Page 25) Upon review of the entire Verizon Network, Verizon provided a Network Map which is placed on Page 23. This Verizon coverage map integrated all sites in the area that exist and/or proposed to indicate the entire network Plan for Verizon for a radius of 5 miles. Comparing the alternative co -location site of the AEP Power Line structure (Page 21) it can be determined that a drop of coverage from the requested 150' site at Cloverdale will leave a substantial "hole" in the coverage. (Page 22) Atlantic Technology Consultants, Inc. Page 16 of 25 Mechanicsville, VA Therefore, looking at the complete Verizon Network map (Page 23) of all planned and existing sites, the Consultant (ATC) believes that the Applicant (Verizon) has demonstrated that the co -location alternative on the AEP site is out of position and alignment and that comprehensive study indicated that the requested Cloverdale site at 150' meets the technical requirements set forth by Roanoke County and that this site improves digital data services and that it should be considered for approval. 3.0 RECOMMENDATIONS This request for approval to construct a 150 -ft monopole tower as proposed represents an appreciable intent on the part of the Applicant to conform to all applicable federal, state, and local regulations. The consultant requests that the County approve the Application/Request for issuance of a Special Use Permit to allow construction of this site. In closing, this consultant remains available to address any comments or questions which may arise following review of this report. Any interested party with such comments or questions may feel free to contact this firm, which remains committed to delivering independent, objective, unbiased, and thorough consulting services.

Total height of the broadcast tower shall not exceed 158 feet. 3. Lighting on the broadcast tower shall not be permitted, unless required by the Federal Aviation Administration (FAA). EXECUTIVE SUMMARY: Drew Patterson, the consultant for Verizon Wireless, is requesting a special use permit to construct a 150 foot high monopole broadcasting tower, with an eight foot high lighting rod. The proposed tower is to be constructed within a 33' by 55' fenced compound area at 7014 Old Mountain Road. The parcel is zoned 1-1, Low Intensity Industrial, district and is 64.62 acres in size. The site is designated Principal Industrial by the 2005 Roanoke County Comprehensive Plan. The proposed project does conform to the Roanoke County Zoning Ordinance and Principal Industrial guidelines. 1. APPLICABLE REGULATIONS A Broadcast Tower is defined as any structure that is designed and constructed primarily for the purpose of supporting one (1) or more antennas. The term includes but need not be limited to radio and television transmission towers, microwave towers, common -carrier towers, and cellular telephone and wireless communication towers. Broadcasting tower types include, but are not limited to monopoles, lattice towers, wooden poles, and guyed towers. Excluded from this definition are amateur radio towers, which are described separately. A Broadcast Tower is permitted in the 1-1, Low Intensity Commercial zoning district with a special use permit. Section 30-87-2 of the Roanoke County Zoning Ordinance provides the use and design standards for a Broadcast Tower. A copy of this section is attached. Roanoke County building permit reviews will be required. The proposed tower is subject to completion and submittal of the National Environmental Policy Act (NEPA) report, Section 106 of the National Historic Preservation Act of 1966 and Federal Aviation Administration (FAA) air space study reports. Additional recommendations may be forthcoming from the Virginia Department of Environmental Quality, Virginia Department of Historic Resources and the Federal Aviation Administration. 2. ANALYSIS OF EXISTING CONDITIONS Background — The applicant reports that no available structures exist within the area of suitable height, design and location to provide needed infill cellular communications between Tinker Mountain, Bonsack and Plantation Road. The applicant has submitted a map of existing tower sites within a 5 mile radius of the proposed site in which Verizon is currently co -located on. Topography/Vegetation — The proposed site is fairly flat. Within the proposed location of the leased 2,400 square foot area, there are a variety of evergreen trees. The majority of the vegetation is located to the east of the proposed site, which serves as an existing buffer adjacent to the railroad tracks and R-3, Medium Density Multi -Family Residential zoned properties. There is currently an existing gravel driveway and parking area adjacent to the proposed leased area. Surrounding Neighborhood — 7014 Old Mountain Road is currently vacant, however this location is part of the overall Bogar Facility development, located at 7500 Shadwell Drive, northwest of the proposed site. The Bogar Facility is comprised of numerous industrial use types. Old Mountain Road is located to the east of the proposed site, and the entire overall 64.62 acre site. Located across Old Mountain Road are R-1 zoned parcels. The closest single-family residence is approximately 300 feet from the proposed broadcasting tower. Located to the south of the property is a vacant 50 -acre parcel zoned 1-1. 3. ANALYSIS OF PROPOSED DEVELOPMENT Site Lavout/Architecture — The submitted building plans indicate a 158 -foot high new monopole broadcasting tower within a 33' by 55' gated, six foot board on board wood fence, compound. The total land area that Verizon is proposing to lease is 2,400 square feet. Additional equipment proposed includes a 7' by 15' concrete platform for the cabinets, a ten foot long ice bridge, 4' by 8' generator concreate pad and various additional ground level equipment. Verizon Wireless antennas are proposed at the 150 foot height location. Co -location options will be made available. The facility will be accessed by an existing driveway from Old Mountain Road. A new Verizon Wireless 20 -foot wide ingress/egress easement and utility right-of- way is also proposed. Existing, mature trees will serve as existing screening for the proposed facility on the north, east and west sides. Very few trees will be removed for the construction of the facility and broadcast tower. The proposed tower will be 213 feet from Old Mountain Road and 300 feet from the closest single family residence. In addition, the proposed tower is over 600 feet from all other property lines. The proposed project is required to meet all federal, state and local building codes and regulations. Complete building plans have been submitted with this application. Historical Analysis — Santec Consulting Services, Inc. has completed their comments in regards to the required Section 106 of the National Historic Preservation Act of 1966 (NHPA). There is one historic resource in close proximately to the proposed project, as listed on the National Register of Historic Places (NRHP). Black Horse Tavern/Bellvue Hotel and Office, is located at 7223 and 7229 Old Mountain Road. The property owners are Francis E. and Judith A. Longaker. The Black Horse tavern was constructed in 1782 and the Bellvue Hotel was constructed in 1854. Other structures on the property were constructed 2 between 1840 and 1930, and include an office, springhouse, shed, garage and swimming pool. Currently, the use of the property is single-family residential and was added to the National Register of Historic Places in 2002. The second historic resource is Bellgrove Farm, which is not currently listed on the NRHP, but is eligible. Stantec Consulting determined that the proposed broadcasting tower, at 158 feet total, would have no adverse visual effect on both the Black Horse Tavern/Bellvue Hotel and Bellgrove Farm. More information can be found in the attached technical review by Atlantic Technology Consultants, Inc. Atlantic Technology Consultants, Inc. — Technical Review — George Condyles, a consultant with Atlantic Technology Consultants, Inc., has reviewed the submitted request and had submitted a technical report, which is attached. Mr. Condyles recommends delaying final approval until the following documents and comments of the respective governmental organizations are received: 1. Completion of The National Environmental Policy Act (NEPA) Report with review comments from the Virginia Department of Environmental Quality. 2. Completion of Section 106 Report with comments from the Virginia Department of Historic Resources and the US Department of Interior. 3. Full Federal Aviation Administration (FAA), Air Apace Study to determine lighting requirements comments from the FAA. 4. Applicant should run Propagation models from the Alternative AEP power mount location and provide written analysis of this potential site. In addition, Mr. Condyles believes the application has "merit" and that while the historic site is important, the historic site is "compromised" and that the addition of the monopole tower on an industrial property will not compromise the historic property. Finally, staff does recommended a condition requiring the above documents from DEQ, VDHR, US Department of Interior and FAA to all be submitted and all recommendations from the respective agencies are met before final building permit approval. Fire & Rescue/Utilities/Office of Buildinq Safety — The Roanoke County Building Commissioner requires building permits and inspections for any property structures, including the service equipment, per the 2012 Virginia Uniform Statewide Building Code. The Roanoke County Fire Marshall's Office does not object to the submitted application. Community Meeting —A community meeting was held at the Roanoke County Fleet Services Center on December 9, 2015 between 5:30 and 8:00 p.m. Over 470 notices were mailed to property owners in close proximity to the proposed site. 11 citizens attended the meeting. Drew Patterson and Lori Schweller, representing Verizon Wireless, were also in attendance. The main concerns expressed during the community meeting were visibility of the tower, coverage questions and specific concerns over the location on the proposed site. 4. CONFORMANCE WITH THE ROANOKE COUNTY COMPREHENSIVE PLAN The 2005 Roanoke County Comprehensive Plan designates the area as Principal Industrial, a future land use area where a variety of industry types are encouraged to locate. Principal Industrial areas are existing and planned regional employment centers and are distributed throughout Roanoke County, convenient to major residential areas and suitable highway access. The proposed broadcast tower conforms to the Principal Industrial guidelines. 5. STAFF CONCLUSIONS Drew Patterson, the consultant for Verizon Wireless, is requesting a special use permit to construct a 150 foot high monopole broadcasting tower, with an eight foot high lighting rod. The proposed tower is to be constructed within a 33' by 55' fenced compound area at 7014 Old Mountain Road. The parcel is zoned 1-1, Low Intensity Industrial, district and is 64.62 acres in size. The proposed project is in conformance with the goals and objectives of the Principal Industrial Future Land Use Designation. Atlantic Technology Consultants, Inc. has provided a technical review of the proposed request and has additional comments that staff is proposing as a suggested condition, if the Planning Commission recommends approval of the special use permit request. Additionally, staff suggests the following conditions which would mitigate the impact of the proposed tower: 1. Total height of the broadcast tower shall not exceed 158 feet. 2. Lighting on the broadcast tower shall not be permitted, unless required by the Federal Aviation Administration (FAA).

If a continuance is warranted, the applicant will be notified of the continuance and the newly scheduled public hearing date. Effective date: April 19, 2005 Name of Petition Petitioner's Signature Date Proposal Verizon Wireless (VZW) is proposing a 158 foot (to the top of the lightning rod) monopole tower on a 64 acre parcel located at 7014 Old Mountain Road in the northeastern portion of Roanoke County. There is a demonstrable need for coverage in this area. Many citizens do not currently have adequate access to high-speed, high-quality internet in their homes and businesses or while they travel on nearby roads and highways. Therefore, the proposed tower will achieve the following: • Enhance the existing wireless network by supporting the latest wireless technologies and provide coverage to the following: o Those living in nearby residential neighborhoods; o Those travelling on Hollins Road, Old Mountain Road and Shadwell Drive; o Those working in the nearby PCA Roanoke packaging and shipping plant, which is less than 750 feet from the tower site; o Future industries that may relocate on the large surrounding I-1, Low Intensity Industrial District, parcels. • Connect the propagation rings of the following nearby VZW towers and essentially fill the coverage "hole" (see attached propagation maps): o Tinker Mountain — Botetourt County - 1896 Tinker Top Road o Bonsack — Botetourt County — 181 Blue Ridge Boulevard o Plantation Road —City of Roanoke - 320 Hershberger Road NW • Provide multiple collocation positions for other wireless carriers to expand their networks. Compatibility with Comprehensive Plan The Roanoke County Land Use Plan designates the subject property as Principle Industrial. The Comprehensive Plan defines Principle Industrial as "areas where high technology industries and research and development firms are present or may develop ". The proposed tower will facilitate existing industries and promote new industries by providing high quality wireless service in the area, which is a necessity for "high technology industries". Chapter 3: Land Use Issues, Design Guidelines, Principle Industrial, Guideline 911, encourages "the siting of communication antennae and dishes on existing or new structures ". VZW always prefers to collocate on existing structures; however, there are not any existing towers or structures that are a sufficient height to meet the coverage objective within this search ring. Therefore, VZW is proposing a new tower on a parcel designated as Principle Industrial, which is consistent with Guideline #11. Chapter 3: Land Use Issues, Citizen Participation, Implementation Strategies #8, states that "Roanoke County should provide its citizens the opportunity to interface with each other and the capability to access all community services through the latest communications technologies". The proposed tower will provide residents, businesses and travelers in the area access to the latest wireless technologies, which is consistent with Implementation Strategy 48. Zoning Ordinance requirements The subject property is zoned I-1, Low Intensity Industrial District. In accordance with Article 3, Section 30-61-2(B)(3), Miscellaneous Uses, of the Roanoke County Zoning Ordinance, broadcasting towers are permitted subject to an approved special use permit. Article 4, Section 30-87-2 of the Zoning Ordinance regulates broadcast towers. The applicable requirements listed in this section are as follows: Sec. 30-87-2. - Broadcasting Tower. (B) Applicability: These standards shall apply to all new and replacement broadcasting towers within Roanoke County with the exception that new and replacement broadcasting towers and associated antenna not exceeding thirty (30) feet in height and located within any commercial or industrial zoning district shall be permitted by right provided: a. The proposed tower is a monopole type design; The proposed tower is a monopole design. b. The general area of the proposed tower is currently served by above ground utilities including electric power and telephone poles; and The general area of the tower is served by above ground utilities. c. All other use and design standards for the construction of the broadcasting tower and associated facilities are met. VZW will comply with all other use and design standards for the construction of the tower and facilities. 2. No modification to increase the height, size, type or location of any existing broadcasting tower or associated facilities, excluding antennas, shall be made unless such modification results in the full compliance of the broadcasting tower and facilities with all of the requirements of this ordinance. Not applicable; this is a new tower. Antennas may be installed on any existing structure within the county, without the necessity of obtaining a special use permit, provided said antenna does not meet the definition of a broadcasting tower, does not increase the height of the existing structure more than ten (10) feet, and does not result in the structure and antenna exceeding the maximum structure height for that zoning district. Not applicable; this is a new tower. 4. These provisions shall not apply to any temporary broadcasting tower erected for the purpose of system design or testing provided the temporary broadcasting tower is erected for a period not to exceed twenty-one (2 1) days. In addition, in declared local emergency situations, the county administrator shall be authorized to allow the temporary installation of a broadcasting tower for the duration of the local emergency. A zoning permit pursuant to section 30-9 of this ordinance shall be applied for and approved prior to erecting any temporary or emergency tower. Not applicable; this is a permanent tower. (C) Application requirements: All potential applicants for broadcasting towers shall consult with county planning staff at least thirty (30) days prior to submitting an application for a proposed broadcasting tower. During this consultation the applicant shall present information to the staff on system objectives, proposed coverage areas, and alternative sites considered and rejected. The staff shall provide the potential applicant information on Roanoke County policies and standards for broadcasting towers, and shall discuss with the applicant possible alternatives to broadcasting tower construction. VZW had a pre -application meeting with Planning staff on 7/13/15. 2. In addition to the application requirements contained in section 30-19-2 of this ordinance, all applicants for broadcasting towers shall provide the following at the time of application: 1. The location of all other proposed broadcasting tower sites considered and rejected, and the specific technical, legal or other reasons for the rejection. In building out its network, VZW first looks to collocate on existing structures (telecommunications towers, transmission power towers, rooftops, etc.) within a search ring. VZW places a strong emphasis on collocation for two reasons: 1) it is the desire of most local governments and 2) it is typically much cheaper than building a new site. Collocation was not an option for the following reasons: • There are no existing towers within the search ring that would meet the coverage objective; • VZW is already collocated on all of the closest towers; • The surrounding area is relatively rural and there are no existing structures tall enough to meet the coverage objective. 2. The location of all other possible collocation sites considered and rejected, and the specific technical, legal or other reasons for the rejection. VZW is already collocated on all of the closest towers and there were no other existing structures within the search ring that are tall enough to meet the coverage objective. 3. Accurate, to scale, photographic simulations showing the relationship of the proposed broadcasting tower and associated antenna to the surroundings. Photographic simulations shall also be prepared showing the relationship of any new or modified road, access or utility corridors constructed or modified to serve the proposed broadcasting tower site. The number of simulations and the perspectives from which they are prepared, shall be established with the staff at the consultation required in section C.1. above. See attached photosimulations. 4. A computerized terrain analysis showing the visibility of the proposed broadcasting tower and antenna at the requested height and location. If new or modified road, access or utility corridors are proposed, the terrain analysis shall also show the visibility of these new or modified features. See attached computerized terrain analysis. Information on how the proposed site relates to the applicants existing communication system, including number of other sites within the Roanoke Valley, and the location of the antenna at each site. See attached propagation maps showing the relationship of the proposed tower to VZW's other tower sites within the area. All broadcasting tower applicants shall be required, at their expense to conduct an on-site "balloon" or comparable test prior to the planning commission and board of supervisors hearings on the special use permit. The purpose of this test shall be to demonstrate the potential visual impact of the proposed tower. The dates and periods of these tests shall be established with the applicant at the pre -application consultation. A balloon test time was conducted on 9/17/15 (see attached photosimulations demonstrating the visual impact of the proposed tower). Written verification that all required submittals to the FAA as required by section 30-87-2(D)6 of this ordinance have been submitted. VZW is required by Federal law to comply with all FAA requirements when constructing a new tower. VZW will obtain all required approvals from the FAA and all other State and Federal agencies. 3. The applicant shall be responsible for all fees associated with the filing of the application including the reasonable cost of any independent analysis deemed necessary by the county to verify the need for the new broadcasting tower. The board of supervisors shall establish these fees, which shall be discussed with the applicant at the pre -application conference. (D) General standards: 1. The maximum height of any proposed broadcasting tower and associated antenna shall be made as a condition of the special use permit, but in no case shall any broadcasting tower and antenna exceed one hundred ninety-nine (199) feet in height. Applicants shall request the lowest broadcasting tower and antenna height necessary to accomplish their specific communication objectives. The proposed tower is 158 feet (to the top of the lightning rod), which is the lowest height necessary to achieve VZW's coverage objective. It should be noted that the proposed height will also allow other wireless carriers sufficient height to meet their coverage objectives. The setback for any proposed broadcasting tower shall, at a minimum, conform to the requirements for principal structures for the proposed zoning district. However, in no case shall the minimum setback from the base of the broadcasting tower to any residential structure on an adjoining lot be less than forty (40) percent of the height of the tower, measured from the closest structural member of the broadcasting tower (excluding guy lines). Guy lines shall be exempt from the minimum setback requirements in side and rear yards for the respective zoning district, but shall comply with the setback requirements for the front yard. The tower is setback 300 feet from the closest residence (7015 Old Mountain Road), which is approximately 150% of the height of the tower. 3. The minimum setback from any property line abutting a road right-of-way for any other building or structure associated with a broadcasting tower shall be fifty (50) feet. Such buildings or structures shall be located a minimum of twenty-five (25) feet from any other property line. The tower is setback 213 feet from the closest property line (i. e. front property line) and over 600 feet from all other property lines. 4. More than one (1) broadcasting tower shall be permitted on a lot provided all applicable requirements have been met including setback requirements. Only one tower is proposed. Broadcasting towers shall not be illuminated with any type of lighting apparatus, unless such lighting is a requirement of the FAA or FCC. When lighting is proposed to conform to federal requirement, the county shall contact the federal agency to verify the necessity of lighting, and to determine the minimal amount and type of lighting necessary to comply with federal guidelines. Security lighting, or a "down lighting" design may be installed on buildings and structures associated with a broadcasting tower. In no case shall any lighting violate section 30-94 of this ordinance. No lighting is proposed with this request. 6. Any proposed broadcasting tower within two (2) miles from any general or commercial airport or located at a ground elevation at or above two thousand (2,000) feet, average mean sea level, shall be referred to the appropriate regional office of the FAA for review and comment prior to filing an application for a special use permit. See attached TOWAIR, which requires FAA notification and FCC registration. When constructing a new tower, VZW is required by law to comply with all FAA and FCC requirements. VZW is currently in the process of obtaining these approvals and will provide the approval documents when complete. 7. All broadcasting towers shall comply with any additional requirements established in the airport overlay district in section 30-72 of this ordinance, and the emergency communications overlay district in section 30-73. VZW agrees to comply with any additional requirements established in the airport overlay district in section 30-72 of this ordinance, and the emergency communications overlay district in section 30-73, if applicable. Any broadcasting tower approved shall be structurally designed to carry sufficient loading, and the site approved shall be sized to accommodate the additional equipment necessary for at least three (3) other vendors/providers of communications services in order to minimize the proliferation of new broadcasting towers in the vicinity of the requested site. In addition, by applying and being granted the special use permit, the applicant and the owner of the land agree to make the broadcasting tower and tower site available for additional leases within the structural capacity of the broadcasting tower and at reasonable costs adequate to recover the capital, operating and maintenance costs of the broadcasting tower location required for the additional capacity. The proposed tower will be structurally designed to carry sufficient loading, and the site approved shall be sized to accommodate the additional equipment necessary for at least three (3) other vendors/providers of communications services. In addition, VZW agrees to make the broadcasting tower and tower site available for additional leases within the structural capacity of the broadcasting tower. 9. A monopole broadcasting tower design is recommended. The board may approve an alternative broadcasting tower design if it finds that an alternative type of structure has less of a visual impact on the surrounding community and Roanoke County, and/or based upon accepted technical and engineering data a monopole design is not technically feasible. Cost shall not be a criteria for determining broadcasting tower design. A monopole tower design is proposed. 10. No broadcasting towers shall be permitted within the critical viewsheds of the Blue Ridge Parkway or Appalachian Trail as shown on any official map designating these viewsheds and pre -approved by the board of supervisors. In addition, no towers shall be proposed within any other designated area of local scenic, historical, ecological and cultural importance as designated and approved by the board of supervisors prior to the filing of a tower application. The proposed tower is not within the critical viewshed of the Blue Ridge Parkway or Appalachian Trail. 11. By applying and being granted the special use permit, the applicant and the owner of the land agree to dismantle and remove the broadcasting tower and associated facilities from the site within ninety days of the broadcasting tower no longer being use for wireless communications. Dismantling and removal from the site shall only be required after notice by the County. If antennas on any approved tower are relocated to a lower elevation, the tower shall be shortened to the height of the highest antenna. A bond or similar performance guarantee may be required as part of the special use permit approval. Said guarantee will be in an amount sufficient to ensure removal of the tower and all associated facilities and the reclamation of the property and road, access and utility corridors to a condition that existed prior to tower construction. VZW agrees to dismantle and remove the broadcasting tower and associated facilities from the site within ninety days of the broadcasting tower no longer being used for wireless communications. 12. All broadcasting tower structures and associated hardware, antennas, and facilities shall be a flat matted finish so as to reduce visibility and light reflection unless otherwise required by the FCC or FAA. The tower and associated hardware will be a flat matted finish so as to reduce visibility and light reflection. 13. No business signs shall be allowed on the property identifying the name of, or services offered by, any business associated with the broadcasting tower. There will be no signage on the tower identifying the name of, or services offered by, any business associated with the broadcasting tower. (E) General review policies: All special use permit requests for new broadcasting towers, including the replacement or modification of existing broadcasting towers shall be reviewed by the staff, planning commission and board of supervisors on the basis of the following criteria: 1. The extent to which the broadcasting tower proposal conforms to the general special use permit criteria in section 30-19 of this ordinance, and the intent, application requirements, and general standards for broadcasting towers found in these provisions. The proposed tower will meet or exceed all special use permit criteria in section 30-19 of the ordinance, and the intent, application requirements, and general standards for broadcasting towers found in these provisions. 2. The demonstrated willingness of the applicant to evaluate collocation opportunities within the proposed communication service area, and the demonstrated history of the applicant choosing collocation sites within the Roanoke Valley. In building out its network, VZW first looks to collocate on existing structures (telecommunications towers, transmission power towers, rooftops, etc.) within a search ring. VZW places a strong emphasis on collocation for two reasons: 1) it is the desire of most local governments and 2) it is typically much cheaper than building a new site. Collocation was not an option for the following reasons: • There are no existing towers within the search ring that would meet the coverage objective; • VZW is already collocated on all of the closest towers; • The surrounding area is relatively rural and there are no existing structures tall enough to meet the coverage objective. 3. The base and top elevation of the proposed broadcasting tower relative to surrounding natural land forms. Notwithstanding any other provision of this section, broadcasting tower locations below surrounding ridge lines are preferred. The proposed tower will be located in a relatively flat area where it will be below surrounding ridgelines. 4. Broadcasting tower locations already served by existing roads and utilities are preferred due to the potential detrimental environmental and visual impacts resulting from the construction of new road and utility corridors. VZW will utilize an existing gravel road to access the facility; therefore, a new entrance will not be required. VZW will attempt to use existing utilities if available. Within the needed service area, the availability of other existing structures that are, based upon independent analysis, of suitable height, design, and location for the needed antenna. VZW always prefers to collocate on existing structures; however, there are not any structures within the search ring that are tall enough to meet the coverage objective. The visibility of the broadcasting tower from the surrounding community and neighborhood compatibility of the tower as determined by the submitted computer simulations, terrain analysis and balloon or comparable test. The attached photosimulations and computerized terrain analysis were created from the balloon test, which was conducted on 9117115. These documents show that the proposed tower will have limited visibility from surrounding streets and residences. 7. The degree to which the proposed tower location, site design and facilities including fencing, buildings and other ground mounted equipment and new or modified road, access or utility corridors are located, designed and constructed to be compatible with the neighborhood. The wireless facility will have limited visibility. Specifically, the tower site has been located and designed as follows to reduce adverse visual effects: • VZW has chosen a 64 acre property where existing mature trees will surround and screen the compound on the north, east and west sides; • VZW has chosen a location on the property where few, if any, trees will need to be removed for construction of the compound and access road, • VZW is proposing a wood board on board fence around the entire compound to ensure that the ground equipment will remain screened from adjacent roads and properties; • VZW will utilize an existing gravel road to access the compound,- therefore, the viewshed from Old Mountain Road will not change significantly with this request; • The tower will be setback over 213 feet from Old Mountain Road - 0 The tower will be setback over 300 feet from the closest residential structure. Zoning Ordinance requirements The subject property is zoned I-1, Low Intensity Industrial District. In accordance with Article 3, Section 30-61-2(B)(3), Miscellaneous Uses, of the Roanoke County Zoning Ordinance, broadcasting towers are permitted subject to an approved special use permit.

The general area of the proposed tower is currently served by above ground utilities including electric power and telephone poles; and The general area of the tower is served by above ground utilities. c. All other use and design standards for the construction of the broadcasting tower and associated facilities are met. VZW will comply with all other use and design standards for the construction of the tower and facilities. 2. No modification to increase the height, size, type or location of any existing broadcasting tower or associated facilities, excluding antennas, shall be made unless such modification results in the full compliance of the broadcasting tower and facilities with all of the requirements of this ordinance. Not applicable; this is a new tower. Antennas may be installed on any existing structure within the county, without the necessity of obtaining a special use permit, provided said antenna does not meet the definition of a broadcasting tower, does not increase the height of the existing structure more than ten (10) feet, and does not result in the structure and antenna exceeding the maximum structure height for that zoning district. Not applicable; this is a new tower. 4. These provisions shall not apply to any temporary broadcasting tower erected for the purpose of system design or testing provided the temporary broadcasting tower is erected for a period not to exceed twenty-one (2 1) days. In addition, in declared local emergency situations, the county administrator shall be authorized to allow the temporary installation of a broadcasting tower for the duration of the local emergency. A zoning permit pursuant to section 30-9 of this ordinance shall be applied for and approved prior to erecting any temporary or emergency tower. Not applicable; this is a permanent tower. (C) Application requirements: All potential applicants for broadcasting towers shall consult with county planning staff at least thirty (30) days prior to submitting an application for a proposed broadcasting tower. During this consultation the applicant shall present information to the staff on system objectives, proposed coverage areas, and alternative sites considered and rejected.

VZW had a pre -application meeting with Planning staff on 7/13/15. 2. In addition to the application requirements contained in section 30-19-2 of this ordinance, all applicants for broadcasting towers shall provide the following at the time of application: 1. The location of all other proposed broadcasting tower sites considered and rejected, and the specific technical, legal or other reasons for the rejection. In building out its network, VZW first looks to collocate on existing structures (telecommunications towers, transmission power towers, rooftops, etc.) within a search ring. VZW places a strong emphasis on collocation for two reasons: 1) it is the desire of most local governments and 2) it is typically much cheaper than building a new site. Collocation was not an option for the following reasons: • There are no existing towers within the search ring that would meet the coverage objective; • VZW is already collocated on all of the closest towers; • The surrounding area is relatively rural and there are no existing structures tall enough to meet the coverage objective. 2. The location of all other possible collocation sites considered and rejected, and the specific technical, legal or other reasons for the rejection. VZW is already collocated on all of the closest towers and there were no other existing structures within the search ring that are tall enough to meet the coverage objective. 3. Accurate, to scale, photographic simulations showing the relationship of the proposed broadcasting tower and associated antenna to the surroundings. Photographic simulations shall also be prepared showing the relationship of any new or modified road, access or utility corridors constructed or modified to serve the proposed broadcasting tower site. The number of simulations and the perspectives from which they are prepared, shall be established with the staff at the consultation required in section C.1. above. See attached photosimulations. 4. A computerized terrain analysis showing the visibility of the proposed broadcasting tower and antenna at the requested height and location. If new or modified road, access or utility corridors are proposed, the terrain analysis shall also show the visibility of these new or modified features. See attached computerized terrain analysis. Information on how the proposed site relates to the applicants existing communication system, including number of other sites within the Roanoke Valley, and the location of the antenna at each site. See attached propagation maps showing the relationship of the proposed tower to VZW's other tower sites within the area. All broadcasting tower applicants shall be required, at their expense to conduct an on-site "balloon" or comparable test prior to the planning commission and board of supervisors hearings on the special use permit. The purpose of this test shall be to demonstrate the potential visual impact of the proposed tower. The dates and periods of these tests shall be established with the applicant at the pre -application consultation. A balloon test time was conducted on 9/17/15 (see attached photosimulations demonstrating the visual impact of the proposed tower). Written verification that all required submittals to the FAA as required by section 30-87-2(D)6 of this ordinance have been submitted. VZW is required by Federal law to comply with all FAA requirements when constructing a new tower. VZW will obtain all required approvals from the FAA and all other State and Federal agencies. 3. The applicant shall be responsible for all fees associated with the filing of the application including the reasonable cost of any independent analysis deemed necessary by the county to verify the need for the new broadcasting tower. The board of supervisors shall establish these fees, which shall be discussed with the applicant at the pre -application conference. (D) General standards: 1. The maximum height of any proposed broadcasting tower and associated antenna shall be made as a condition of the special use permit, but in no case shall any broadcasting tower and antenna exceed one hundred ninety-nine (199) feet in height. Applicants shall request the lowest broadcasting tower and antenna height necessary to accomplish their specific communication objectives. The proposed tower is 158 feet (to the top of the lightning rod), which is the lowest height necessary to achieve VZW's coverage objective. It should be noted that the proposed height will also allow other wireless carriers sufficient height to meet their coverage objectives. The setback for any proposed broadcasting tower shall, at a minimum, conform to the requirements for principal structures for the proposed zoning district. However, in no case shall the minimum setback from the base of the broadcasting tower to any residential structure on an adjoining lot be less than forty (40) percent of the height of the tower, measured from the closest structural member of the broadcasting tower (excluding guy lines). Guy lines shall be exempt from the minimum setback requirements in side and rear yards for the respective zoning district, but shall comply with the setback requirements for the front yard. The tower is setback 300 feet from the closest residence (7015 Old Mountain Road), which is approximately 150% of the height of the tower. 3. The minimum setback from any property line abutting a road right-of-way for any other building or structure associated with a broadcasting tower shall be fifty (50) feet. Such buildings or structures shall be located a minimum of twenty-five (25) feet from any other property line. The tower is setback 213 feet from the closest property line (i. e. front property line) and over 600 feet from all other property lines. 4. More than one (1) broadcasting tower shall be permitted on a lot provided all applicable requirements have been met including setback requirements. Only one tower is proposed. Broadcasting towers shall not be illuminated with any type of lighting apparatus, unless such lighting is a requirement of the FAA or FCC. When lighting is proposed to conform to federal requirement, the county shall contact the federal agency to verify the necessity of lighting, and to determine the minimal amount and type of lighting necessary to comply with federal guidelines. Security lighting, or a "down lighting" design may be installed on buildings and structures associated with a broadcasting tower. In no case shall any lighting violate section 30-94 of this ordinance. No lighting is proposed with this request. 6. Any proposed broadcasting tower within two (2) miles from any general or commercial airport or located at a ground elevation at or above two thousand (2,000) feet, average mean sea level, shall be referred to the appropriate regional office of the FAA for review and comment prior to filing an application for a special use permit. See attached TOWAIR, which requires FAA notification and FCC registration. When constructing a new tower, VZW is required by law to comply with all FAA and FCC requirements. VZW is currently in the process of obtaining these approvals and will provide the approval documents when complete. 7. All broadcasting towers shall comply with any additional requirements established in the airport overlay district in section 30-72 of this ordinance, and the emergency communications overlay district in section 30-73. VZW agrees to comply with any additional requirements established in the airport overlay district in section 30-72 of this ordinance, and the emergency communications overlay district in section 30-73, if applicable. Any broadcasting tower approved shall be structurally designed to carry sufficient loading, and the site approved shall be sized to accommodate the additional equipment necessary for at least three (3) other vendors/providers of communications services in order to minimize the proliferation of new broadcasting towers in the vicinity of the requested site. In addition, by applying and being granted the special use permit, the applicant and the owner of the land agree to make the broadcasting tower and tower site available for additional leases within the structural capacity of the broadcasting tower and at reasonable costs adequate to recover the capital, operating and maintenance costs of the broadcasting tower location required for the additional capacity. The proposed tower will be structurally designed to carry sufficient loading, and the site approved shall be sized to accommodate the additional equipment necessary for at least three (3) other vendors/providers of communications services. In addition, VZW agrees to make the broadcasting tower and tower site available for additional leases within the structural capacity of the broadcasting tower. 9. A monopole broadcasting tower design is recommended. The board may approve an alternative broadcasting tower design if it finds that an alternative type of structure has less of a visual impact on the surrounding community and Roanoke County, and/or based upon accepted technical and engineering data a monopole design is not technically feasible. Cost shall not be a criteria for determining broadcasting tower design. A monopole tower design is proposed. 10. No broadcasting towers shall be permitted within the critical viewsheds of the Blue Ridge Parkway or Appalachian Trail as shown on any official map designating these viewsheds and pre -approved by the board of supervisors. In addition, no towers shall be proposed within any other designated area of local scenic, historical, ecological and cultural importance as designated and approved by the board of supervisors prior to the filing of a tower application. The proposed tower is not within the critical viewshed of the Blue Ridge Parkway or Appalachian Trail. 11. By applying and being granted the special use permit, the applicant and the owner of the land agree to dismantle and remove the broadcasting tower and associated facilities from the site within ninety days of the broadcasting tower no longer being use for wireless communications. Dismantling and removal from the site shall only be required after notice by the County. If antennas on any approved tower are relocated to a lower elevation, the tower shall be shortened to the height of the highest antenna. A bond or similar performance guarantee may be required as part of the special use permit approval. Said guarantee will be in an amount sufficient to ensure removal of the tower and all associated facilities and the reclamation of the property and road, access and utility corridors to a condition that existed prior to tower construction. VZW agrees to dismantle and remove the broadcasting tower and associated facilities from the site within ninety days of the broadcasting tower no longer being used for wireless communications. 12. All broadcasting tower structures and associated hardware, antennas, and facilities shall be a flat matted finish so as to reduce visibility and light reflection unless otherwise required by the FCC or FAA. The tower and associated hardware will be a flat matted finish so as to reduce visibility and light reflection. 13. No business signs shall be allowed on the property identifying the name of, or services offered by, any business associated with the broadcasting tower. There will be no signage on the tower identifying the name of, or services offered by, any business associated with the broadcasting tower. (E) General review policies: All special use permit requests for new broadcasting towers, including the replacement or modification of existing broadcasting towers shall be reviewed by the staff, planning commission and board of supervisors on the basis of the following criteria: 1. The extent to which the broadcasting tower proposal conforms to the general special use permit criteria in section 30-19 of this ordinance, and the intent, application requirements, and general standards for broadcasting towers found in these provisions. The proposed tower will meet or exceed all special use permit criteria in section 30-19 of the ordinance, and the intent, application requirements, and general standards for broadcasting towers found in these provisions. 2. The demonstrated willingness of the applicant to evaluate collocation opportunities within the proposed communication service area, and the demonstrated history of the applicant choosing collocation sites within the Roanoke Valley. In building out its network, VZW first looks to collocate on existing structures (telecommunications towers, transmission power towers, rooftops, etc.) within a search ring. VZW places a strong emphasis on collocation for two reasons: 1) it is the desire of most local governments and 2) it is typically much cheaper than building a new site. Collocation was not an option for the following reasons: • There are no existing towers within the search ring that would meet the coverage objective; • VZW is already collocated on all of the closest towers; • The surrounding area is relatively rural and there are no existing structures tall enough to meet the coverage objective. 3. The base and top elevation of the proposed broadcasting tower relative to surrounding natural land forms. Notwithstanding any other provision of this section, broadcasting tower locations below surrounding ridge lines are preferred. The proposed tower will be located in a relatively flat area where it will be below surrounding ridgelines. 4. Broadcasting tower locations already served by existing roads and utilities are preferred due to the potential detrimental environmental and visual impacts resulting from the construction of new road and utility corridors. VZW will utilize an existing gravel road to access the facility; therefore, a new entrance will not be required. VZW will attempt to use existing utilities if available. Within the needed service area, the availability of other existing structures that are, based upon independent analysis, of suitable height, design, and location for the needed antenna. VZW always prefers to collocate on existing structures; however, there are not any structures within the search ring that are tall enough to meet the coverage objective. The visibility of the broadcasting tower from the surrounding community and neighborhood compatibility of the tower as determined by the submitted computer simulations, terrain analysis and balloon or comparable test. The attached photosimulations and computerized terrain analysis were created from the balloon test, which was conducted on 9117115. These documents show that the proposed tower will have limited visibility from surrounding streets and residences. 7. The degree to which the proposed tower location, site design and facilities including fencing, buildings and other ground mounted equipment and new or modified road, access or utility corridors are located, designed and constructed to be compatible with the neighborhood. The wireless facility will have limited visibility. Specifically, the tower site has been located and designed as follows to reduce adverse visual effects: • VZW has chosen a 64 acre property where existing mature trees will surround and screen the compound on the north, east and west sides; • VZW has chosen a location on the property where few, if any, trees will need to be removed for construction of the compound and access road, • VZW is proposing a wood board on board fence around the entire compound to ensure that the ground equipment will remain screened from adjacent roads and properties; • VZW will utilize an existing gravel road to access the compound,- therefore, the viewshed from Old Mountain Road will not change significantly with this request; • The tower will be setback over 213 feet from Old Mountain Road - 0 The tower will be setback over 300 feet from the closest residential structure.

Broadcasting Tower. (A) Intent: The intent of these provisions is to regulate the placement of new and replacement broadcasting towers within Roanoke County. These provisions provide broadcasting tower applicants, property owners, and all other Roanoke County citizens clear guidance on the official policies and standards of the County. These policies and standards shall be used by applicants as a guide when selecting alternative broadcasting tower sites and broadcasting tower designs within the county. In addition, the county staff, planning commission and board of supervisors shall use these policies and standards, the Roanoke County community plan and the general special use permit criteria found in section 30-19 as a guide for evaluating any future requests for broadcasting towers. In the interest of preserving and enhancing the scenic and natural beauty of Roanoke County it is the goal of the county to achieve a long term reduction in the number of broadcasting towers within the county, and where possible, to achieve a reduction in the height of existing broadcasting towers throughout the county, with special emphasis on towers located along or near the ridgetops of major mountains and land forms. In addition, it is the goal of the county, where possible, to achieve the relocation of existing broadcasting towers and associated utility and access corridors which have a high visual impact on scenic resources. To this end, the county will work cooperatively with broadcasting tower owners and applicants and land owners to achieve these goals. It is the official policy of the county to encourage and promote the collocation of antennas on existing public and private structures within the county. To achieve this end, the county encourages all wireless communication providers to locate new antennas on existing structures. Permits for new broadcasting towers should only be requested when no other reasonable alternative exists for locating needed antennas. When new broadcasting towers are proposed as a last alternative, the requested broadcasting tower location, height and design should be chosen to protect and enhance the scenic and natural beauty of Roanoke County. Broadcasting tower locations at elevations lower than surrounding ridge lines are preferred. The use of stealth designs should be considered for any new broadcasting tower. It is the intent of the county to fully comply with all of the applicable provisions of the federal Telecommunications Act of 1996 and other applicable federal and state laws as said laws address and preserve Roanoke County's zoning authority and provide to the communication industry the right and responsibility to provide communication services within their service areas. (B) Applicability: These standards shall apply to all new and replacement broadcasting towers within Roanoke County with the exception that new and replacement Use & Design Standards — Miscellaneous Uses broadcasting towers and associated antenna not exceeding thirty (30) feet in height and located within any commercial or industrial zoning district shall be permitted by right provided: a. The proposed tower is a monopole type design; b. The general area of the proposed tower is currently served by above ground utilities including electric power and telephone poles; and All other use and design standards for the construction of the broadcasting tower and associated facilities are met. 2. No modification to increase the height, size, type or location of any existing broadcasting tower or associated facilities, excluding antennas, shall be made unless such modification results in the full compliance of the broadcasting tower and facilities with all of the requirements of this ordinance. Antennas may be installed on any existing structure within the county, without the necessity of obtaining a special use permit, provided said antenna does not meet the definition of a broadcasting tower, does not increase the height of the existing structure more than ten (10) feet, and does not result in the structure and antenna exceeding the maximum structure height for that zoning district. 4. These provisions shall not apply to any temporary broadcasting tower erected for the purpose of system design or testing provided the temporary broadcasting tower is erected for a period not to exceed twenty-one (2 1) days. In addition, in declared local emergency situations, the county administrator shall be authorized to allow the temporary installation of a broadcasting tower for the duration of the local emergency. A zoning permit pursuant to section 30-9 of this ordinance shall be applied for and approved prior to erecting any temporary or emergency tower. (C) Application requirements: All potential applicants for broadcasting towers shall consult with county planning staff at least thirty (30) days prior to submitting an application for a proposed broadcasting tower. During this consultation the applicant shall present information to the staff on system objectives, proposed coverage areas, and alternative sites considered and rejected. The staff shall provide the potential applicant information on Roanoke County policies and standards for broadcasting towers, and shall discuss with the applicant possible alternatives to broadcasting tower construction. 2. In addition to the application requirements contained in section 30-19-2 of this ordinance, all applicants for broadcasting towers shall provide the following at the time of application: 2 Use & Design Standards — Miscellaneous Uses a. The location of all other proposed broadcasting tower sites considered and rejected, and the specific technical, legal or other reasons for the rejection. b. The location of all other possible collocation sites considered and rejected, and the specific technical, legal or other reasons for the rejection. C. Accurate, to scale, photographic simulations showing the relationship of the proposed broadcasting tower and associated antenna to the surroundings. Photographic simulations shall also be prepared showing the relationship of any new or modified road, access or utility corridors constructed or modified to serve the proposed broadcasting tower site. The number of simulations and the perspectives from which they are prepared, shall be established with the staff at the consultation required in section C.1. above. d. A computerized terrain analysis showing the visibility of the proposed broadcasting tower and antenna at the requested height and location. If new or modified road, access or utility corridors are proposed, the terrain analysis shall also show the visibility of these new or modified features. e. Information on how the proposed site relates to the applicants existing communication system, including number of other sites within the Roanoke Valley, and the location of the antenna at each site. f. All broadcasting tower applicants shall be required, at their expense to conduct an on-site "balloon" or comparable test prior to the planning commission and board of supervisors hearings on the special use permit. The purpose of this test shall be to demonstrate the potential visual impact of the proposed tower. The dates and periods of these tests shall be established with the applicant at the pre -application consultation. g. Written verification that all required submittals to the FAA as required by section 30-87-2(D)6 of this ordinance have been submitted. 3. The applicant shall be responsible for all fees associated with the filing of the application including the reasonable cost of any independent analysis deemed necessary by the county to verify the need for the new broadcasting tower. The board of supervisors shall establish these fees, which shall be discussed with the applicant at the pre -application conference. (D) General standards: The maximum height of any proposed broadcasting tower and associated antenna shall be made as a condition of the special use permit, but in no case shall any broadcasting tower and antenna exceed one hundred ninety-nine (199) feet in Use & Design Standards — Miscellaneous Uses height. Applicants shall request the lowest broadcasting tower and antenna height necessary to accomplish their specific communication objectives. 2. The setback for any proposed broadcasting tower shall, at a minimum, conform to the requirements for principal structures for the proposed zoning district. However, in no case shall the minimum setback from the base of the broadcasting tower to any residential structure on an adjoining lot be less than forty (40) percent of the height of the tower, measured from the closest structural member of the broadcasting tower (excluding guy lines). Guy lines shall be exempt from the minimum setback requirements in side and rear yards for the respective zoning district, but shall comply with the setback requirements for the front yard. The minimum setback from any property line abutting a road right-of-way for any other building or structure associated with a broadcasting tower shall be fifty (50) feet. Such buildings or structures shall be located a minimum of twenty-five (25) feet from any other property line. 4. More than one (1) broadcasting tower shall be permitted on a lot provided all applicable requirements have been met including setback requirements. Broadcasting towers shall not be illuminated with any type of lighting apparatus, unless such lighting is a requirement of the FAA or FCC. When lighting is proposed to conform to federal requirement, the county shall contact the federal agency to verify the necessity of lighting, and to determine the minimal amount and type of lighting necessary to comply with federal guidelines. Security lighting, or a "down lighting" design may be installed on buildings and structures associated with a broadcasting tower. In no case shall any lighting violate section 30-94 of this ordinance. 6. Any proposed broadcasting tower within two (2) miles from any general or commercial airport or located at a ground elevation at or above two thousand (2,000) feet, average mean sea level, shall be referred to the appropriate regional office of the FAA for review and comment prior to filing an application for a special use permit. 7. All broadcasting towers shall comply with any additional requirements established in the airport overlay district in section 30-72 of this ordinance, and the emergency communications overlay district in section 30-73 8. Any broadcasting tower approved shall be structurally designed to carry sufficient loading, and the site approved shall be sized to accommodate the additional equipment necessary for at least three (3) other vendors/providers of communications services in order to minimize the proliferation of new broadcasting towers in the vicinity of the requested site. In addition, by applying and being granted the special use permit, the applicant and the owner of the land agree to make the broadcasting tower and tower site available for additional leases El Use & Design Standards — Miscellaneous Uses within the structural capacity of the broadcasting tower and at reasonable costs adequate to recover the capital, operating and maintenance costs of the broadcasting tower location required for the additional capacity. 9. A monopole broadcasting tower design is recommended. The board may approve an alternative broadcasting tower design if it finds that an alternative type of structure has less of a visual impact on the surrounding community and Roanoke County, and/or based upon accepted technical and engineering data a monopole design is not technically feasible. Cost shall not be a criteria for determining broadcasting tower design. 10. No broadcasting towers shall be permitted within the critical viewsheds of the Blue Ridge Parkway or Appalachian Trail as shown on any official map designating these viewsheds and pre -approved by the board of supervisors. In addition, no towers shall be proposed within any other designated area of local scenic, historical, ecological and cultural importance as designated and approved by the board of supervisors prior to the filing of a tower application. 11. By applying and being granted the special use permit, the applicant and the owner of the land agree to dismantle and remove the broadcasting tower and associated facilities from the site within ninety days of the broadcasting tower no longer being use for wireless communications. Dismantling and removal from the site shall only be required after notice by the County. If antennas on any approved tower are relocated to a lower elevation, the tower shall be shortened to the height of the highest antenna. A bond or similar performance guarantee may be required as part of the special use permit approval. Said guarantee will be in an amount sufficient to ensure removal of the tower and all associated facilities and the reclamation of the property and road, access and utility corridors to a condition that existed prior to tower construction. 12. All broadcasting tower structures and associated hardware, antennas, and facilities shall be a flat matted finish so as to reduce visibility and light reflection unless otherwise required by the FCC or FAA. 13. No business signs shall be allowed on the property identifying the name of, or services offered by, any business associated with the broadcasting tower. (E) General review policies: All special use permit requests for new broadcasting towers, including the replacement or modification of existing broadcasting towers shall be reviewed by the staff, planning commission and board of supervisors on the basis of the following criteria: The extent to which the broadcasting tower proposal conforms to the general special use permit criteria in section 30-19 of this ordinance, and the intent, application requirements, and general standards for broadcasting towers found in Use & Design Standards — Miscellaneous Uses these provisions. 2. The demonstrated willingness of the applicant to evaluate collocation opportunities within the proposed communication service area, and the demonstrated history of the applicant choosing collocation sites within the Roanoke Valley. 3. The base and top elevation of the proposed broadcasting tower relative to surrounding natural land forms. Notwithstanding any other provision of this section, broadcasting tower locations below surrounding ridge lines are preferred. 4. Broadcasting tower locations already served by existing roads and utilities are preferred due to the potential detrimental environmental and visual impacts resulting from the construction of new road and utility corridors. Within the needed service area, the availability of other existing structures that are, based upon independent analysis, of suitable height, design, and location for the needed antenna. 6. The visibility of the broadcasting tower from the surrounding community and neighborhood compatibility of the tower as determined by the submitted computer simulations, terrain analysis and balloon or comparable test. 7. The degree to which the proposed tower location, site design and facilities including fencing, buildings and other ground mounted equipment and new or modified road, access or utility corridors are located, designed and constructed to be compatible with the neighborhood.

Atlantic Technology Consultants, Inc. Page 5 of 28 Mechanicsville, VA The proposed tower is a 150 -ft monopole tower with an 8 -ft lightning rod (for a total AGL of 158 -ft) placed within a 33'x 55' fenced compound. The site will be accessed from Old Mountain Road. (See Detailed Site Plan below) The center of the proposed tower is located at coordinates 370 20' 36.00" N and 790 55'02.18" W (NAD 83). Atlantic Technology Consultants, Inc. Page 6 of 28 Mechanicsville, VA 1.2 Topography The topography of this site is relatively flat. The ground elevation for the proposed tower is 1250' above sea level. The tower is proposed at 150' + an 8' Lightning Rod for an overall height of 158'. Combining the Ground elevation of 1250'+ 158' would give an Average Mean Above Sea Level of 1400' AMSL. The Consultant has reviewed the information supplied and concurs to the height of the tower as conditions relative to the topography. Site placement is in an open area adjacent to the ball field in the southeast corner of the property. The access to the site is on an existing gravel road that is shielded by some pine and hardwood trees. The existing tree canopy is between 40 and 70 feet in most places. The site has a natural tree buffer around it and will cause very little land disturbance. The site (as for the topography) is well suited and will serve many residential and commercial facilities with advanced wireless broadband services. Atlantic Technology Consultants, Inc.

HomeFusion Broadband offers customers a reliable alternative for residential broadband, especially in areas with limited broadband choices. It provides connectivity Atlantic Technology Consultants, Inc. Page 8 of 28 Mechanicsville, VA for a wide range of devices, including computers and gaming consoles, using the Verizon 4G LTE network, which is now available in 230 markets covering more than two-thirds of the population in the United States. "HomeFusion Broadband is another example of Verizon Wireless' commitment to providing their customers with the most innovative products and services," said Tami Erwin, vice president and chief marketing officer, Verizon Wireless. "With HomeFusion Broadband, customers across the United States, in towns large and small, will have the chance to link devices to the Internet and take advantage of the speed, coverage and connectivity offered by the Verizon 4G LTE network." How it works HomeFusion Broadband uses a professionally installed, cylinder -shaped antenna attached to a customer's home. The antenna's innovative design includes multiple internal antennae, allowing the device to pick up the best Verizon 4G LTE signal available and transmit it to a broadband router inside the home. The router can connect up to four wired and at least 20 wireless devices inside the home using Wi-Fi. In real-world, fully loaded network environments, Verizon 4G LTE customers, including HomeFusion Broadband customers, should experience average data rates of 5 to 12 megabits per second (Mbps) on the downlink and 2 to 5 Mbps on the uplink. 1.3 Setbacks The proposed site is over 213' from the nearest primary road, Old Mountain Road, to the north. All property line setbacks required for this area have been observed in the drawing (Page C -1A) of the enclosed site plans, including those with respect to nearby residences and adjacent property lines. As noted in the application package the proposed tower is approximately 300 feet from the nearest adjacent property line which is in compliance with the County's setback requirements. 1.4 Co -Location While co -location is preferable to construction of a new site, with such co - location minimizing visual impact of telecommunications equipment on the surrounding area, no additional sites are available in the area which would meet the Applicant's coverage objectives. Atlantic Technology Consultants, Inc. Page 9 of 28 Mechanicsville, VA The Applicant has submitted a map and of existing tower sites within a 5 - mile radius of the proposed tower site. Verizon is essentially on all existing towers. This site is a fill-in site within the network. Another potential site is an AEP Power Line structure. There are several AEP Power line structures approximately 4,250 south of the proposed site. While these may not be ideal from a horizontal alignment, if there is an issue due to the Historic and Environmental Federal Requirements, this could be a potential solution as an Alternative Site. Currently, NTelos is co -located on one of these.

Page 11 of 28 Mechanicsville, VA NTELOS Site Co -located on AEP Power Line 4,250' to the south on Old Mountain Road The construction of the facility as proposed will verifiably meet the stated coverage objectives of the Applicant. The application makes detailed reference to all applicable points of consideration regarding County preference for co - location of equipment on existing structures versus new tower construction. The Consultant believes that there is potential of an alternative AEP Structure co -location if the Primary site is unviable. Atlantic Technology Consultants, Inc. Page 12 of 28 Mechanicsville, VA 1.5 Structural The proposed 158' monopole tower design is of high strength steel, and represents a highly stable structural design not known by this consultant to have failed at any installation in this region. This structure, as proposed, is well within compliance of EIA/TIA-222-G guidelines for structures mandated ability to withstand the structural loading of all appurtenances, plus additional wind and ice loading. This tower structure, as proposed, would allow room for future co -location of at least three (3) additional wireless Land Mobile Radio carriers at the same site, minimizing the number of towers needed for all wireless telecommunications carriers to eventually optimize service in this area. Furthermore, in conformance with County, work at this site will remain in compliance with ALL federal, state, and local building codes and regulations if work proceeds as outlined in the application. The applicant's proposal includes site plans representing a soundly engineered design conforming to industry standards. 1.6 RF Exposure FCC bulletin OET-65 provides guidance for a licensee proposing to construct a telecommunications support structure in calculation of RF exposure limitations, including analysis of the cumulative effect of all transmitters on the structure. Appropriate steps, including warning signage at the site, will be taken to protect both the general public and site workers from unsafe RF exposure in accordance with federal guidelines. Verizon has agreed in writing to be in compliance with all FCC requirements. The consultant sees no evidence of unsafe RF exposure levels being generated at this site if it were to proceed as proposed. RF site exposure warning signage placement is appropriately planned for this site. 1.7 Grounding Grounding of all structures and equipment at an RF site is critically important to the safety of both personnel and equipment at the site Even a single component not meeting this standard places all other site components at risk for substantial damage. All structures and equipment at the site should maintain a ground potential difference of less than 5 ohms. If construction Atlantic Technology Consultants, Inc. Page 13 of 28 Mechanicsville, VA proceeds as proposed, all structures and equipment shall be appropriately grounded and any obvious grounding deficiencies rectified for safety purposes and minimizing the potential for a situation to occur requiring mitigation. 1' . 5 These concerns have been addressed within the Planning Drawings. The Consultant believes these to meet the NEC and Virginia Building Code requirements. 1.8 General Safety This site compound (33' x 55') will be surrounded by suitable 6 -ft high board on board wood fence to prevent unauthorized access to the tower site, as clearly indicated in the proposed site plans. Additional safety measures to be placed at this site should include: - RF exposure warning signage - Site identification information - Routine and Emergency contact information - No Trespassing signs Furthermore, OSHA -approved style of fall prevention cable, and an anti -climbing device shall be installed.

Atlantic Technology Consultants, Inc. Page 14 of 28 Mechanicsville, VA 1.9 Interference An interference study, taking into account all proximally located transmitters and receivers known to be active in the area are advisable prior to any new tower construction. The Applicant, Verizon, has agreed to the requirements of monitoring and resolving any radio interference that may be attributed to this structure if any interference would occur. Practically speaking this consultant sees no evidence of interference by or with this site after a general evaluation of the surrounding transmitter sites. Should any interference issues be posed with respect to this site, mitigation would nevertheless remain the responsibility of the FCC License Owner and affected carrier(s), and would be regulated by the Federal Communication Commission and/or the Federal Aviation Administration, having no effect or burden on the County. 2.0 PROCEDUREAL 2.1 FAA Study A full FAA Study to determine potential Air Hazard requirements for this tower was not submitted with this Application by Verizon. The TOWAIR was included. Because this report's Determination Results indicated that it "Failed Slope away & exceeds by 36.0 meters (118.11 -ft)," it is the recommendation that a Full Air Space Study be performed and results given as to Air Obstruction and Marking as per 47 C.F.R. Section 17.7 and 14 C.F.R. Section 77.13 and FAA AC 70/7460-1 K. Until a Full Air Space Study is complete it is not known if this tower will be required to be marked or Lite as per FAA Guidelines. Atlantic Technology Consultants, Inc. Page 15 of 28 Mechanicsville, VA 1219!2015 TOWAIR Search Results TOWAIR Determination Results This structure requires FAA notification and FCC registration, based on a check of the coordinates, heights, and structure type you provided. As detailed below, one or more of the determination results produced a "fail slope" result, which means registration is required. *** NOTICE *** TOWAIR's findings are not definitive or binding, and we cannot guarantee that the data in TOWAIR are fully current and accurate. In some instances, TOWAIR may yield results that differ from application of the criteria set out in 47 C.F.R. Section 17.7 and 14 C.F.R. Section 77.13. A positive finding by TOWAIR recommending notification should be given considerable weight. On the other hand, a finding by TOWAIR recommending either for or against notification is not conclusive. It is the responsibility of each ASR participant to exercise due diligence to determine if it must coordinate its structure with the FAA. TOWAIR is only one tool designed to assist ASR participants in exercising this due diligence, and further investigation may be necessary to determine if FAA coordination is appropriate.

This will be determined after the Full Airspace Study is conducted. 2.3 Environmental Impacts The National Environmental Policy Act of 1969 (NEPA), delineated in Title 47 of the Code of Federal Regulations, Part 1, Subpart I, sections 1.1301-1.1319, requires federal agencies to incorporate environmental considerations into their decision-making process when evaluating new construction proposals. As a licensing agency, the Federal Communication Commission (FCC) requires all licensees to consider the potential environmental effects from their construction of antenna support structures, and to disclose those effects in an Environmental Assessment (EA) that must be filed with the FCC for review. The Applicant has not submitted a NEPA Review with VDEQ Comments. The Consultant recommends the completion of the NEPA Report with review comments from the Virginia Department of Environmental Quality. 2.4 Historic Impacts Section 106 of the National Historic Preservation Act of 1966 (NHPA) requires that State Historic Preservation Offices (SHPO) and the President's Advisory Council on Historic Preservation be given a reasonable opportunity to comment on all undertakings with the potential to affect historic properties. Prior to construction, the licensee is required to submit to the SHPO a detailed description of the project, a listing of local historic resources, and a discussion of any measures being undertaken to mitigate impacts (if any) on historic resources. Upon receipt, the SHPO has thirty (30) days to review and respond to those submissions. All agencies with authority to permit construction are required to consider the SHPO response in its decision making process with respect to new construction applications. The Consultant recommends the completion of Section 106 Report with comments from the Virginia Department of Historic Resources and the US Department of Interior. Atlantic Technology Consultants, Inc. Page 18 of 28 Mechanicsville, VA The Applicant has included the September 29, 2015 report from Stantec Consulting Services, Inc. of Glen Allen, Virginia as backup for the Applicant's Section 106 Historic Review Study which is to be reviewed and compiled by Geo - Technology Associates, Inc. of Sterling Virginia who is responsible for the NEPA and Section 106 Review. The State Historic Preservation Officer of Virginia in the Department of Historic Resources will review the entire document of the Section 106 and make comments concerning the study or place further exploration requirements on said proposed site. Stantec Comments and recommendations: Conclusions View shed analysis of the NRHP-listed Black Horse Tavern/ Bellvue Hotel and Office Historic District (VDHR # 080-5143) and the NRHP-eligible Bellegrove Farm (VDHR # 080-0407) conducted within the 0.5 -mile APE, determined that the proposed maximum height of 158 feet for the cellular tower would be visible from Photo Locations 1 and 6 for the resources under consideration. At Bellegrove Farm (VDHR # 080-0407), the tower at the maximum height of 158 feet was not visible from Photo Location 3, but was visible from Location 1. At the height of 158 feet, it is recommended that the proposed cellular tower will have a visual effect on Bellegrove Farm, but not an adverse visual effect. At Black Horse Tavern/ Bellvue Hotel and Office Historic District (VDHR # 080-5143), the tower at the maximum height of 158 feet was not visible from Photo Location 6, but was visible at 120 feet. The proposed tower at the maximum height of 158 feet was not visible from the remaining locations within the district (Locations 4, 5, 7, 8, and 9). At the height of 158 feet, it is recommended that the proposed cellular tower will have a visual effect, but not an adverse visual effect on Black Horse Tavern/ Bellvue Hotel and Office Historic District. Overall it is recommended that the proposed Cloverdale telecommunications tower will have no adverse visual effect on the NRHP-listed resource and NRHP-eligible resource at 158 feet. Should you have any questions or would like additional information, please do not hesitate to contact me at 757-831-3979 or by email at ellen.brady4,stantec.com Sincerely, Ad�m�� Ellen M. Brady Senior Principal Investigator I IIIL Sandra DeChard Senior Architectural Historian The report can be summarized by reducing the original height from 199' AGL to 158' AGL, that this new height would not have an Adverse Visual Effect on the Historic Sites. The Consultant concurs with this finding. Atlantic Technology Consultants, Inc. Page 19 of 28 Mechanicsville, VA Consultant's research (Source: Wikipedia) Black Horse Tavern-Bellvue Hotel and Office is an historic inn and tavern complex located at Hollins, Roanoke County, Virginia. The complex consists of: 1. The Black Horse Tavern (c. 1782) 2. The Greek Revival style Bellvue Hotel (also known as Kyle's Hotel) (c. 1854) 3. The temple -fronted, Greek Revival style brick Office (c. 1840). 4. The Spring House (c. 1900) 5. The shed (c. 1930). The Black Horse Tavern is a simple, one story, three -bay log structure. The Bellvue Hotel is a two-story, five -bay, brick structure with a central -passage, double -pile plan. The office is a simple, one-story, one -bay brick structure. It features a wide frieze band and a front portico with a pedimented gable supported by squared Doric order columns. The buildings housed a school for physically and mentally handicapped children and the property became known as Bellevue School during the mid -20th century. The school closed in 1976, and the buildings house a single family residence. It was added to the National Register of Historic Places in 2003. Consultant's comments: 1. While this site is a treasure to the community, the obvious construction of the Bogar LLC plant located on Industrially Zoned property over 25 years ago has compromised the site. The Industrial plant in clear view of the front of the Bellvue House and other buildings is unobstructed. 2. The property became a registered Historic Property in 2003, clearly long after the Zoning of the Bogar property to Industrial (1-1). 3. The tower will be viewed by the community, but is off to the south approximately 2,500 from the historic property. 4. The tower site and service providers will bring new wireless broadband to the community with "HomeFusion" and this will eliminate home copper telephone line to the residences. Simply put, technology will advance not at the expense of history. In summary, the Consultant believes that this Application has "merit" and that while the historic site is important, that the situation of the historic site is "compromised" and that the addition of this monopole tower on a Industrial property will not compromise the historic property.

Mechanicsville, VA Page 21 of 28 2.5 Radio Frequency Coverage Analysis Applicant's Data Verizon is proposing a 158 -ft monopole tower. This tower will address the lack of 4-G/AWS coverage along Rt. 11. The Observer can see how significant the hole is and how this area of the county is underserved. The Atlantic Group Evaluation The Atlantic Group would request the additional propagation models be produced by the Applicant as soon as possible so that the Consultant can evaluate what the difference may be and thus render an opinion. The Atlantic Group ran an independent RF analysis for this site. We see that there is a need to file an RF data "Hole" in this area as defined by the Applicant's Radio Frequency Propagation models on pages 24 and 25 of this report, if the proposed tower is not approved because of Land Use unsuitability and conformance, that the AEP Power Line Structure approximately 4,250 feet south or .8 mile is the only other "opportunity" for co -location. Verizon is currently co -located on every tower in the immediate vicinity so the proposed tower is Verizon's first choice. The difference in coverage or "Penalty" for co -locating on the AEP Power line by our calculations is about 10% in coverage area. The Atlantic Group supports the original proposed site and height of 158' AGL with co -location potential for three (3) additional carriers. Atlantic Technology Consultants, Inc. Page 22 of 28 Mechanicsville, VA 3.0 RECOMMENDATIONS This request for approval to construct a 158 -ft monopole tower as proposed represents an appreciable intent on the part of the Applicant to conform to all applicable federal, state, and local regulations. The Consultant recommends: 1. Completion of the NEPA Report with review comments from the Virginia Department of Environmental Quality. 2. Completion of Section 106 Report with comments from the Virginia Department of Historic Resources and the US Department of Interior. 3. Full FAA Air Space Study to Determine Lighting Requirement comments from the FAA. 4. Applicant should run Propagation models from an Alternative AEP Power mount location and provide written analysis of this potential site. If these recommendations are agreed upon by the Applicant, the consultant will request the County approve the Application/Request for issuance of a Special Use Permit to allow construction of this site. In closing, this consultant remains available to address any comments or questions which may arise following review of this report. Any interested party with such comments or questions may feel free to contact this firm, which remains committed to delivering independent, objective, unbiased, and thorough consulting services.

Bellvue Swimming fool ca. 2000 Non-contributing Summary Description Roanoke, Virginia The proposed Black Horse Tavern/Bellvue Hotel and Office property is composed of two adjacent parcels of land containing 4.15 acres along the east side of Old Mountain Road in northeast Roanoke County. Situated at the base of Read Mountain along a section of the old Carolina Road, these two parcels contain the ca. 1782 Black Horse Tavern, the ca. 1854 Greek - Revival style Bellvue Hotel (also known as Kyle's Hotel) and the ca. 1840 temple -fronted, brick Office. Other resources on the property include a ca. 1900 springhouse and a ca. 1930 shed as well as a newly -constructed garage and swimming pool. The Black Horse Tavern, originally part of the "Stone House Tract" granted to Israel Christian in 1764 and situated on the Carolina Road, is a rare surviving example of a late 18"' century tavern with its log construction covered by early German siding. The ca. 1854 Bellvue Hotel, originally constructed by William and James Kyle to serve as an upgrade to the tavern, is a typical example of a two-story brick dwelling designed in the Greek -Revival style with simple, symmetrical plan and detailing. Later modifications include the early addition of a kitchen wing as well as front and rear porches and dormers that date to the 1930s, when the house and office were used as a private school. The ca. 1840 Bellvue Office, which predates the house and possibly served as an office for James Kyle, is an unusual example in the area of a one-story, brick office building with a temple front. The two parcels remained in various branches of the related Luck -Rowland -Kyle families until the 1930s. NPS Form 10-900-a (8-86) United States Department of the Interior National Park Service National Register of Historic Places Continuation Sheet Section __ 3Page 2 Detailed Description OMH No. 1OS4.0018 Black Horse Tavern /Bellvue House and Office Roanoke, Virginia Black Horse Tavern The ca. 1782 Black Horse Tavern stands close to Old Mountain Road and the route of the Carolina Road. This simple, one story, three -bay structure is constructed of partially -hewn logs with V -notching on a solid foundation of stacked stones. Wide boards of German siding attached with pre -1850 cut nails sheath the log structure. Two exterior -end chimneys of stacked stone (now covered with stucco) with two sets of shoulders frame the side gable roof. The roof is covered with asphalt shingles, however, the original wood shakes of the roof still exist where a rear addition attaches to the original structure. Double -hung sash windows with 6/6 lights flank the single -leaf door composed of two lights over two vertical panels. A three -bay frame porch with a shed roof supported by squared columns and balustrades extends across the front. The interior features a single -pile, central passage plan in the original structure. A two-story frame ell wing, constructed in the late 19`" century, extends from the rear of the log structure. This addition features a two-story side porch along the north elevation. Many of the changes to the original log structure, including the doors, windows, and stucco on the chimneys date to this period or the early 1900s. A small ca. 1930 frame shed with German siding and shed roof stands to the rear of the house. Bellvue Hotel Approximately 154 yards to the southeast of the Black Horse Tavern stands the ca. 1854 Bellvue Hotel. Constructed by James and William Kyle and also known as "Kyle's Hotel," the Greek - Revival style house stands further back from the road than the tavern with a wide open lawn. Large mature trees surround the house and line the roadbed of the Carolina Road.

Outbuildings and Landscape Features The Black Horse Tavern/Bellvue Hotel and Office property is located on a 4.15 -acre tract of land along Old Mountain Road (the Carolina Road) at the base of Read Mountain in northeast Roanoke. The original roadbed of the Carolina Road is visible alongside the present Old Mountain Road. Several large, mature trees serve to define the line of the old road. A 1935 sketch map of the property indicates the location of a stable across the road, which was torn down in the late 19{h century. The Black Horse Tavern sits close to the roadbed with two large trees in front. A ca. 1935 frame shed with German siding and shed roof stands to the rear of the tavern. There is no formal landscaping or gardens around the tavern structure. The Bellvue Hotel and Office sit further back from the road with a large open lawn in front. An historic photograph depicts a picket fence extending along the roadbed. Landscape features are minimal, consisting of large mature trees scattered across the lawn and boxwood hedges along the foundation. Other outbuildings on the property include a ca. 1900 frame springhouse immediately behind Bellvue Hotel with weatherboard siding, early concrete foundation and gable roof and a newly -constructed frame garage with gable roof. A swimming pool and rear terrace have also been installed recently.

Statement of Significance OMB No. 1024.0018 Black Horse Tavern /Bellvue House and Office Roanoke, Virginia The proposed Black Horse Tavern/Bellvue Hotel and Office property is a rare surviving example of a complex of late -18`h to mid -19"' century tavern and hotel buildings located on the Carolina Road in northeast Roanoke County. Situated at the base of Read Mountain on a section of the Carolina Road now known as Old Mountain Road, the approximately 4.15 -acre property contains the ca. 1782 Black Horse Tavern, the ca. 1854 Greek -Revival style Belivue Hotel and the ca. 1840 temple -fronted Bellvue Office. The Black Horse Tavern, a simple log structure covered with German siding, stands as possibly the earliest surviving tavern in Roanoke County. The Bellvue Hotel, which was constructed in 1854 by William and James Kyle, was also known as Kyle's Hotel and includes an unusual example of a ca. 1840 Greek -Revival style brick office building with a pedimented portico. Originally part of the "Stone House Tract" granted to Israel Christian in 1764, the two adjacent properties have been owned and operated by several related families that have figured prominently in the early history of Roanoke, including Thomas Madison, John B. Luck, William Rowland, and James Kyle. Strategically located along the Carolina Road, the primary route from Pennsylvania to the Yadkin Valley of North Carolina, both Black Horse Tavern and Bellvue Hotel provided lodging as ordinaries or houses of private entertainment for settlers following the Great Road from Pennsylvania through Virginia. The Black Horse Tavern/Bellvue Hotel and Office property is eligible for National Register listing under Criteria A and C with significance on the local level in the areas of commerce, transportation, architecture, commerce, and education for the period 1782 to 1951. Historical Background The 4,15 -acres included in the property were originally part of the "Stone House Tract" granted to Israel Christian in 1764 in a section of Botetourt County that would later become Roanoke County, In 1779, Thomas Madison purchased 1,410 acres of this tract from William Christian. Thomas Madison was married to Susannah Henry, sister of Patrick Henry and William Christian's wife, Ann Henry. Thomas Madison, who practiced law, also came from a prominent early Virginia family. He was the son of John Madison of Augusta County, who was a cousin of President James Madison. Thomas Madison's siblings were prominent figures in the settlement of southwest Virginia: two sisters and one brother were married to members of the General Andrew Lewis family; one brother, William, was married to Elizabeth Preston, the daughter of Colonel William Preston of Smithfield Plantation in Montgomery County; and the Reverend NPS Form 18-900.9 (8.86) United States Department of the Interior National Park Service National Register of Historic Places Continuation Sheet Section 8 Page 6 OMB No. 1024-0018 Black Horse Tavern /Bellvue House and Office Roanoke, Virginia James Madison was Bishop of Virginia and president of the College of William and Mary.' The Black Horse Tavern was established by Thomas Madison as early as 1782 and is cited as one of seven taverns licensed to operate in the area between 1770 and 1800.2 The Black Horse Tavern was well situated on the Carolina Road, a section of the Great Wagon Road that ran from Philadelphia through the Shenandoah Valley of Virginia to North Carolina's Yadkin Valley. Following the route of the Great Warrior Path, the Great Wagon Road extended south from Staunton in 1745 and continued to grow after the Treaty of Paris in 1763. By 1765, most sections were cleared for horse-drawn vehicles.3 During this period before the Revolutionary War, the Great Wagon Road was "the most heavily traveled road in all America. ,4 Following Thomas Madison's death in 1789, John B. Luck purchased 364 acres "on Tinker Creek on both sides of the Great Road," including the Black Horse Tavern, from Thomas Madison Jr. in 1815 5 John B. Luck is listed as one of eleven licensed tavern operators in the early 18005 and "Luck's Tavern" is depicted in John Wood's 1821 Map of Botetourt County." The Botetourt County Land Tax Records indicate that the property included a structure valued at $600.7 Prior to Luck's death in 1832, the Black Horse Tavern property was subdivided by his heirs. In 1830, Matilda Luck Thompson sold approximately 360 acres of land, including the Black Horse Tavern, to William Rowland, who was married to her sister, Nancy Luck Rowland.$ William Rowland was one of the early founders of Roanoke having leased fib acres in partnership with Major Kemp Gaines in 1834 and subdivided it into lots that would become Gainsboro.9 William Rowland died in 1838. A WPA record states that "the Black Horse Tavern ceased to exist as such upon the death of William Rowland in 1835" and the furniture of the tavern was sold. includin: six beds, a walnut desk, five candlesticks, a cherry bureau, a clothes press, and one cupboard. After Rowland's death, Nancy Luck Rowland married James Kyle, another prominent early citizen of Roanoke who served as Justice of the Peace in 1838 and 1849 and as a sheriff in 1846. It appears that James Kyle may have continued to operate the Black Horse Tavern as he is listed in 1838 as one of 23 tavern operators in Roanoke County." The 1839 Roanoke County Land Tax records list James Kyle as owner of 81 acres inherited by his wife. This property included a building valued at $600.12 James Kyle and his brother Captain William Kyle purchased 40.5 acres of land adjacent to the tavern tract from George Luck in 1840 and an additional 63 acres from the heirs of William Rowland. 13 The value of buildings on the original 91 acre tract inherited by James Kyle's wife NPS Form 10.900-a (8-86) United States Department of the Interior National Park Service National Register of Historic Places Continuation Sheet Section S Page 7 OMB No. 1024.0018 Black Horse Tavern /Bellvue House and Office Roanoke, Virginia increased in 1844 from $600 to $1200, indicating either the construction of the small brick office or the addition of siding to the tavern. By 1841, Land Tax Records indicate the Kyle brothers held a total of 304 acres conveyed by the Luck and Rowland heirs, including the building valued at $1200 and a new building worth $1004.14 They constructed the Bellvue Hotel, also known as Kyle's Hotel, in 1854.5 References indicate that the brick office was associated with the business of the hotel, however, its unusually high level of design for an outbuilding, with its Greek -Revival style portico, may be associated with James Kyle's public positions in the county, Bellvue operated as a hotel until 1875, when a niece of William Kyle, Helen Davis Thompson, inherited the property. Descendents of Mrs. Thompson share her recollections that bar fixtures from the hotel were removed from the house at that time. 16 The brick office was used as a school for the neighborhood children during this period.17 In the 1930s, both the Black Horse Tavern and Bellvue passed from the hands of the Luck -Rowland -Kyle family when the Rowlands sold the tavern property to the Lockard family and the Thompsons sold Bellvue to Mrs. Leah Knoch James of Ohio. Mrs. James operated a school for physically and mentally handicapped children and the property became known as Bellevue School during the mid -20'4 century.1g The school, which boarded approximately 15 to 20 students, provided a much-needed living and learning environment for the handicapped children of wealthy families that could afford to send them to a private institution. Mrs. James lived on the third floor and the children were boarded on the second floor, The office was used as a schoolhouse. Meals were served in the formal dining room, using china and crystal to promote good social etiquette, Piano, dancing, and singing lessons were also part of the curriculum. Sunday school classes wore provided in the schoolhouse each week by Ms. Laura Norwood, director of the Children's Evangelism and fellowship Organization. Ms. Norwood also helped Mrs. James with celebrating children's birthdays and arranging field trips to the circus and other attractions, Each school session concluded on the Fourth of July with families attending a celebration that included recitations, speeches, and other presentations. The Bellevue School operated for nearly half a century until it closed in 1976.14 Many of the changes to the house, including the porch, dormers, and rear addition as well as the replacement of windows on the east fagade of the office date to this occupation when the property was used as a boarding school. After the school closed, Bellvue was restored as a private residence and continues in that use today.
