Proposed Land Use: Mixed-use property that will accommodate restaurant, retail, residential, and lodging uses Specified Future Land Use: General Commercial A. NATURE OF REQUEST A request by the Town of Vinton, for a variance of specific requirements set forth in the FO-Floodplain Overlay District of the Vinton Zoning Ordinance. The purpose of this request is to allow for the redevelopment of the historic Gish Mill properties, located at 350 and 0 Gus Nicks Boulevard, Vinton, Virginia, Tax Map Numbers 060.11-04-22.00-0000 and 060.11-04-23.00-0000. The variance, if granted, will include all necessary redevelopment activities for the conduct of a functionally dependent use provided that: a. The criteria of Article IV, Division 13, Sec. 4-73 of the zoning ordinance are met, and b. The structure or other development is protected by methods that minimize flood damage during the base flood and create no additional threats to public safety. B. APPLICABLE REGULATIONS The specific sections of which the Town of Vinton are requesting variances from are denoted in Section I below. The specific sections of Article IV, Division 13, FO Floodplain Overlay District, include the following: • Sec. 4-70 (c) (1): Non-Residential Construction Elevation Requirements (Freeboard Requirements) • Sec. 4-71 (b) (2): Floodway Area: Special Use Requirement • Sec. 4-72 (a): Existing structures in floodplain areas. C. ANALYSIS OF EXISTING CONDITIONS Background – Being the founding structure for the Town of Vinton, the Gish Mill site bears a substantial amount of historical significance for the locality. In fact, the Mill is featured as the crown jewel of the Town’s seal. Although the mill operated continuously since the 1770s, in its final years of occupancy it was used as a farm supply retail store and warehouse which ultimately closed in December 2014. Unfortunately, decades of deferred maintenance and exposure to the elements contributed to its current deleterious condition and the necessity of major repairs and improvements. Beyond its historical significance, the mill site is currently positioned both geographically and strategically to have a catalytic impact on the area’s economic, vocational, and cultural growth. In addition to being within the designated Downtown UDA, the project site is specifically located along the major gateway to the Downtown corridor and is the first major landmark individuals see when they enter the Town of Vinton on Gus Nicks Boulevard. Reactivating this commercial and historic mill at the gateway to Vinton will provide a vibrant welcome to residents, and visitors, and to those passing through on their way to Smith Mountain Lake and Blue Ridge Parkway. The Town of Vinton purchased the 1.154 acres property in October of 2015, due to the historical significance to the community and the Town’s eventual charter in 1884. Council’s desire has been to preserve and encourage the structure to be rehabilitated and eventually returned to commercial use. Following the issuance of a Request for Proposal (RFP) in 2019, the Town of Vinton received a formal proposal from Gish Mill Davii, LLC, to convert the historic property into a mixed- use development with the following uses: a small restaurant, a seasonal market, a speakeasy in the basement, and the conversion of the original mill structure, concrete silos, and upper floors of the original mill structure into lodging with potential use for apartment units (3-10 rooms). The anticipated tenant to operate the restaurant and lodge has already been secured for the project. Since the acquisition, the Town of Vinton has completed Phase I and Phase II environmental assessments, has completed the historic reviews necessary for the property to be preliminary determined for individual listing on the National Register by the Department of Historic Resources (DHR), and obtained grant funds from two state government agencies which make the project financially feasible. The first grant from the DHR Emergency Supplemental Historic Preservation Fund (ESHPF) grant program includes $250,000 in available funding for repair and stabilization work to take place on the property. The second grant to the Town is to be administered in the form of a loan of $468,750 through the Economic Development Authority (EDA) from the Department of Housing and Community Development (DHCD) Industrial Revitalization Fund (IRF). The redevelopment project will generate private investment in excess of $1.9 Million and establish the creation of approximately 41 jobs and result in the rehabilitation of a historic, yet currently-blighted property that is located on one of four main gateway entrances into the Town with an average daily traffic count of 21,000 vehicles per day based on 2019 Virginia Department of Transportation (VDOT) data. The site is also located along the proposed Glade Creek Greenway extension, which will link Downtown Vinton and Vinyard Park to the extensive Roanoke Valley Greenway system. The Town of Vinton has also secured Virginia Department of Transportation (VDOT) Surface Transportation Block Grant (STBG) funds to construct a pedestrian mid-block crossing on Gus Nicks Boulevard to provide a safe means of travel to the Gish Mill site from the soon to be constructed Glade Creek Phase II project and the newly redeveloped 84-unit apartment building (Billy Byrd Apartments). Overall, this project is currently of the highest priority for the Town of Vinton in the realm of redevelopment and there is not another vacant and deteriorated property that has the potential for the level of economic and social impact that this site could bring to the area. Location – 350 and 0 Gus Nicks Boulevard, Vinton, Virginia. Former Holdren’s County Store. The parcels can be accessed from Gus Nicks Boulevard and West Madison Avenue. Topography/Vegetation – The existing structure is located adjacent to Glade Creek on a level lot that is comprised mostly of impervious surfaces. In relation to its special location, the Gish Mill, in serving its historic milling purposes, is located in the regulatory floodway and Special Flood Hazard Areas (SFHA) of the Glade Creek floodplain. Because the Town of Vinton is a FEMA Community Rating System (CRS) Class 8 Community, Town staff are diligent in administering the highest forms of regulatory controls for development and activities in the Town’s floodplain areas. Adjacent Zoning and Land Uses – The land uses within the vicinity of the subject property are summarized below. Direction from Property Zoning District Land Use (Chalaine’s) and Sign Manufacturing (Sav’ On Signs) D. ANALYSIS OF PROPOSED DEVELOPMENT Site Layout/Architecture - The developer’s intended use for the mill site is to incorporate several value- added compatible uses, which launch from popular trends that work very well with the open format historic space. The building will be designed to feature several uses that take advantage of the creekside location, the unconventional construction methods, and varying dimensions and angles featured by the mill space. The specific uses include a small restaurant, a seasonal market, a speakeasy in the basement, and the conversion of the original mill structure, concrete silos, and upper floors of the original mill structure into lodging or apartments (3-10 units). The anticipated tenant to operate the restaurant and lodge has already been secured for the project. The development also includes substantial outdoor spaces including dining, deck, and patio space. The historic “sluice” will be utilized as an intimate seating area with stairs that cascade down to the creek. Based on the preliminary floor plans, the development will include: (1) Restaurant (back of house, kitchen, and dining space): 5,030 square feet (First floor) (2) Market: 1,250 square feet (First floor) (3) Speakeasy: 1,296 square feet (Basement) (4) Original Mill and silos converted into lodging/apartments: 5,800 square feet (Second and Third floor) (5) Outdoor dining, deck and patio space: 3,564 square feet (including new deck and patio area located on existing slab, remaining from demolition of an unsafe wing of the building.) Many of the existing mature trees will be retained. The existing sidewalk connections will be retained and will be extended into the site providing pedestrian access from each direction of Gus Nicks. The existing asphalt parking areas will be redeveloped and landscaped for 28 off-street parking spaces including two accessible spaces. Additionally, there exists an opportunity for a substantial overflow parking area adjacent to West Madison Avenue. The historic building will be preserved and sensitively adapted for mixed uses. The building will retain its architectural character and its environmental setting. Visible changes to the exterior of the property and building will be minor. The Mixed-Use Development District will allow this space to be used for flexible space, offering opportunities for community activities, music, and special events perhaps including “movie nights” utilizing the historic building façade for an outdoor projection area. Please see attached survey, property map, aerial photography, and conceptual site plan including parking areas and floor plans of the structure in Appendix A. The Development Team will present a conceptual 3- D rendering of the future interior and exterior renovations to the property to Town Council during the briefing on this request. If the rezoning request for the parcels is approved by the Town Council, a formal site plan for the Project must be submitted for review and approval by the Town of Vinton and County of Roanoke. Parking – As shown in the submitted conceptual plan, the internal Gish Mill site will allow 28 off-street parking spaces including two accessible spaces. There is also opportunity for parking adjacent to West Madison Avenue that could potentially provide over 13 off-site spaces, which will bring the total parking space count to about 41. Site Access – The parcel can currently be accessed from Gus Nicks Boulevard and West Madison Avenue via two (2) commercial entrances that accommodate for both ingress and egress. The Town of Vinton has also secured VDOT Surface Transportation Block Grant (STBG) funds to construct a pedestrian mid- block crossing on Gus Nicks Boulevard to provide a safe means of travel to the Gish Mill site from the soon to be constructed Glade Creek Phase II project and the newly redeveloped 84-unit apartment building (Billy Byrd Apartments). Utilities – Public water and sewer services are available for the existing structure. E. COMPREHENSIVE PLAN/FUTURE LAND USE The 2004 – 2024 Town Comprehensive Plan designates this property and the surrounding properties to the southeast as a general commercial land use area. The properties to the west of this property (across Gus Nicks Boulevard) are designated as parks and recreation, community facilities, and high density residential uses. The properties to the west were rezoned to Mixed Use Development (MUD) in 2016 to allow for the existing vacant school buildings to be adaptively reused as residential and recreational/small business flex space. F. FACTORS TO BE CONSIDERED BY THE BOARD OF ZONING APPEALS (BZA) In consideration of specific variance requests, the BZA shall satisfy all relevant factors and procedures specified in other sections of the zoning ordinance and consider the following additional factors: a. The danger to life and property due to increased flood heights or velocities caused by encroachments. No variance shall be granted for any proposed use, development, or activity within any floodway area that will cause any increase in the 100-year flood elevation; b. The danger that materials may be swept on to other lands or downstream to the injury of others; c. The proposed water supply and sanitation systems and the ability of these systems to prevent disease, contamination, and unsanitary conditions; d. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owners; e. The importance of the services provided by the proposed facility to the community; f. The requirements of the facility for a waterfront location; g. The availability of alternative locations not subject to flooding for the proposed use; h. The compatibility of the proposed use with existing development and development anticipated in the foreseeable future; i. The relationship of the proposed use to the comprehensive plan and floodplain management program for the area; j. The safety of access by ordinary and emergency vehicles to the property in time of flood; k. The expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters expected at the site; l. The historic nature of a structure. Variances for repair or rehabilitation of historic structures may be granted upon a determination and notification from the Register of Historic Places or the state inventory of historic places that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure; m. Such other factors which are relevant to the purposes of this division. G. NO-RISE CERTIFICATION (HYDROLOGIC AND HYDRAULIC STUDY (H&H STUDY)) The Town utilized the consulting services of Draper Aden Associates to verify that the proposed redevelopment project would not cause a rise in the base flood elevation. The consultants were able to utilize the plans of the proposed improvements from the development team and implement them into the flood models. The conclusion of this H&H study was that the proposed project will not cause a rise in the base flood elevations. Both the “Memorandum” from the consultant and the signed “No-Rise Certificate” can be found in Appendix B of this report. H. SUBSTANTIAL IMPROVEMENT PROVISION The Gish Mill structure meets the definition of a “historic structure” set out in the definition section of the Ordinance. Specifically, the Gish Mill structure meets the definition of subsection (a) pertaining to being “preliminary determined” for individual listing on the National Register. The letter attached in Appendix C states that the Virginia “Department of Historic Resources has evaluated the property and has determined that is appears to be eligible for inclusion in the Virginia Landmarks Register. In accord with the provisions of Sec. 58.1-339.2 of the Code of Virginia, then, the property is a certified historic structure.” Both the Town of Vinton and the development team understand that meeting this definition does not automatically exempt this project and its associated activities from the requirements of the floodplain ordinance. However, specific variances from the floodplain ordinance are denoted in Section I below. Additionally, the Town and the development team understand that Historic structures undergoing repair or rehabilitation that would constitute a substantial improvement as defined above, must comply with all requirements of this division that do not preclude the structure's continued designation as a historic structure. Documentation that a specific ordinance requirement will cause removal of the structure from the National Register of Historic Places or the state inventory of historic places must be obtained from the Secretary of the Interior or the state historic preservation officer. Any exemption from ordinance requirements will be the minimum necessary to preserve the historic character and design of the structure. To aid in this process, all of the work being completed during both the repair and stabilization phase and the overall redevelopment phase will be reviewed and approved of by the Department of Historic Resources before it proceeds. In fact, this is a requirement of both the DHR grant guidelines and the overarching commitment in seeking historic tax credits at the end of this redevelopment project. I. SPECIFIC VARIANCES FOR PROPERTY/PROJECT 1. Sec. 4-70 (c) (1): Non-Residential Construction Elevation Requirements (Freeboard Requirements) a. Textual citation: “Non-residential construction. New construction or substantial improvement of any commercial, industrial, or non-residential building (or manufactured home) shall have the lowest floor, including basement, elevated to or above one foot above the base flood level. Buildings located in AE and AH zones may be flood-proofed in lieu of being elevated provided that all areas of the building components below the elevation corresponding to the base flood elevation plus one foot are water tight with walls substantially impermeable to the passage of water, and use structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy. A registered professional engineer or architect shall certify that the standards of this subsection are satisfied. Such certification, including the specific elevation (in relation to mean sea level) to which such structures are floodproofed, shall be maintained by the floodplain administrator.” b. Justification: i. The basement has remained untouched by contemporary materials. The stone walls are exposed as are the first floor joists, the heavy timber structural elements, and the dirt floor. The basement contains a significant amount of milling machinery including wheels, conveyor belts, and grain hoppers. The historic significance and nature of the basement (in addition to the historic pieces of equipment including the wheel base that was powered by water flow from the sluice) warrant this area of the structure being preserved and utilized with an adaptive reuse, which will preclude it from meeting this elevation requirement. ii. The original central block historically served as the hub of industrial activity with grinding taking place on the first floor and cleaning on the second and third floors. Historic timber columns and beams are partially visible on the first floor of the original block. The rear room on the first floor features exposed brick walls and wood rafters. Some of the historic equipment remains intact in this room. The ca. 1846 brick block at the center, comprised of three stories with a full basement, housed the processing operations during the entirety of the building’s use as a mill. This section is capped by a ca. 1940 gambrel roof clad with metal and stands on an uncoursed stone foundation. The hand-made brick walls are laid in six-course common bond; the third story is covered with aluminum siding. Several double- hung wood sash windows that are 6/6 remain extant on the second story. A ca. 1940 concrete block loading dock appends the front elevation. The base of this concrete loading dock is clad with stone veneer and is sheltered by a wood-frame awning covered with metal. The historic significance and nature of the original mill structure warrant this area of the structure being preserved and utilized with an adaptive reuse, which will preclude it from meeting this elevation requirement. iii. A ca. 1930 three-story concrete addition appends the west side elevation of the original block. This addition contains nine grain bins. It is covered with a metal shed roof with exposed rafter tails. A conveyor belt, which dumped the grain into the storage bins, extends over the roof. The conveyor belt is sheltered by a penthouse clad with wood boards and covered by a metal shed roof. There are no window or door openings in this addition. The historic significance and nature of these concrete grain bins warrant this area of the structure being preserved and utilized with an adaptive reuse, which will preclude it from meeting this elevation requirement. iv. A 1940s one-story frame addition, constructed in two phases, appends the east side elevation of the original block. This addition is L-shaped in plan and stands on a concrete foundation. The exterior walls and shed roof are covered with metal siding. The earlier addition directly appends the original central block. The window openings on the front and rear elevations are covered with plywood boards. Double- hung 1/1 wood sash windows remain intact behind the plywood boards on the front elevation. A six-light casement window remains intact behind one of the plywood boards on the rear elevation. The addition was built for storage space, per the 1951 Sanborn Fire Insurance map. The historic significance and nature of this area of the structure warrant it being preserved and utilized with an adaptive reuse, which will preclude it from meeting this elevation requirement. v. A later 1940s addition appends the east side of the earlier 1940s addition. These two additions were built in two different building campaigns as the demising wall was originally built as an exterior wall as a portion of Bricktex siding remains intact on what would have been the exterior wall. This addition is rectangular in plan and stands on a concrete foundation. Like the earlier addition, the exterior walls and shed roof are covered with metal siding. There are six-light wood casement windows on the rear elevation and a single wood z-braced door on the front elevation in a double-leaf door opening; the other z-braced door was previously removed. This door opening is covered with metal siding on the exterior. The addition was built for storage space, per the 1951 Sanborn Fire Insurance map. . The historic significance and nature of this area of the structure warrant it being preserved and utilized with an adaptive reuse, which will preclude it from meeting this elevation requirement. vi. Two one-story, post-1955, storefront additions append the front elevation of the original block and the ca. 1930 concrete grain bin addition. The western one-story concrete block addition has a metal shed roof. The eastern addition was constructed post-1984 is of frame construction. This addition stands on a concrete block foundation clad with stone veneer. The exterior walls are clad with vertical wood boards. The shed roof is covered with metal. Plywood boards cover the window and door openings in these two additions. The door openings contain ¾-light metal doors and the windows contain 3/1 double-hung wood sash windows (likely salvaged from another property) and aluminum-frame storefront windows. The historic significance and nature of this area of the structure warrant it being preserved and utilized with an adaptive reuse, which will preclude it from meeting this elevation requirement. c. Proactive Measures being Undertaken: i. A post-1955 addition appends the later 1940s addition mentioned above. This narrow, triangular addition stands on a concrete foundation. The form of this addition is dictated by the topography of the land and the trajectory of Glade Creek. The frame walls are covered with metal siding. The shed roof is covered with metal. The front elevation contains sliding metal freight doors. A small concrete dock extends from the front elevation of this addition. This non-historic component is actually being removed early in timeline of the project, and the existing concrete foundation will be utilized as a patio space for outdoor dining and leisure. ii. To the fullest extent possible, the electrical, heating, ventilation, plumbing, air conditioning equipment and other service facilities, including duct work, shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding. These service facilities will originate above the Design Flood Elevation (DFE) and will extend downward from the ceiling in such a way to keep them from being damaged during flood events. iii. Wet flood-proofing measures will be used for the building. Such measures allow for flood water to enter and exit the building. The strategy includes a series of vents that allow the movement of water through the building and decreasing the pressure on the existing walls. iv. The crawlspace area under the 1940s additions will not be used for storage or human inhabitation. v. All sleeping quarters will be located well-above (2+ feet) above the base flood elevation within the structure. 2. Sec. 4-71 (b) (2): Floodway Area: Special Use Requirement a. Textual citation: “The following uses, types, and activities are permitted, provided that they are in compliance with the provisions of the underlying zoning district and are not prohibited by any other ordinance and provided that no specific land use requires any type of structure, fill, or storage of materials and equipment:…” b. Justification: i. The property is going through the rezoning process, which requires the approval of the Vinton Town Council. The nature of the floodplain requirements and the results of the hydrologic and hydraulic study (and attainment of the no-rise certificate) will be presented in full detail in all staff reports and presentation to both the Planning Commission and the Town Council. ii. Additionally, the documentation and studies to be presented to the Planning Commission and Town Council will already meet and/or exceed the requirements of the “procedures for special uses in the floodways.” As to not duplicate processes and hearings, in addition to the sufficiency of the information to be presented on at the briefings and work sessions, the special use requirement should not be required for this project. 3. Sec. 4-72 (a): Existing structures in floodplain areas. a. Textual citation: “A structure or use of a structure or premises which lawfully existed before the enactment of these provisions, but which is not in conformity with these provisions, may be continued subject to the following conditions: (a) Existing structures in the floodway area shall not be expanded or enlarged unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practices that the proposed expansion would not result in any increase in the base flood elevation. b. Justification: i. In addition to the variances sought in relation to the elevation/freeboard requirements, it should be requested that the property be exempted from the expansion and enlargement limitation of Sec. 4-72 (a). ii. As noted in the Section D above, 3,564 square feet of the redevelopment will be utilized for outdoor dining, deck and patio space (including a new deck and patio area located on the existing slab). The deck will not be structurally attached to the main structure in anyway; rather it will designed and constructed to resist the force of flood forces through exemplary anchoring techniques. Town staff and the development team understand that this deck will not be a coverable expense by a National Flood Insurance Program (NFIP) policy. Because of the crucial nature of the outdoor space to the financial feasibility of this project, and it being designed using the best contemporary architectural and engineering practices to resist flood forces, the deck and the utilization of the existing concrete slab shall be exempted from this requirement. c. Proactive Measures being Undertaken: i. The H&H study included these proposed improvements which demonstrates that is will not result in any increase in the base flood elevation. ii. The anchoring of the deck will utilize the historic sluice/race as its main foundational component. J. STAFF CONCLUSION Based on the information provided and the completion of critical studies (H&H study, attainment of no- rise certificate, etc.), Town staff find that this proposed redevelopment project meets the criterion of: a. Showing of good and sufficient cause; and b. Determination that failure to grant these variances will result in exception hardship and the ultimate loss of an important Historic structure that is preliminary determined for individual listing on the National Register by the Virginia Department of Historic Resources (DHR); and c. Sufficiently presented, through engineering studies by engineering consultants, that granting these variances will not result in: i. Unacceptable or prohibited increases in flood heights; ii. Additional threats to public safety; or iii. Extraordinary public expense; and will not: 1. Create nuisances; 2. Cause fraud or victimization of the public; or 3. Conflict with local laws or ordinances. If granted, the BZA shall notify the applicant for a variance, in writing that the issuance of a variance to construct a structure below the 100-year flood elevation: a. Increased the risks to life and property; and b. Will result in increased premium rates for flood insurance.

Gish Mill is an historic structure adjacent to Glade Creek and is within the creek’s regulatory floodplain and floodway. The proposed improvements were analyzed to confirm the impacts will not cause a rise in the base flood elevation. The proposed work is within a Special Flood Hazard Zone, identified as Zone AE on the attached FEMA Flood Insurance Rate Map No. 51161C0167G dated September 28, 2007. Flood Modeling As the first step, a duplicate effective model (DEM) was run using HEC-RAS 5.0 to check for changes in the base flood elevation (BFE) between the model and the original HEC-2 output, as provided by the Town. The following table shows the difference between the HEC-2 and DEM base flood elevations. Station HEC-2 BFE, feet DEM BFE, feet 4048 919.0 919.5 4150 918.7 919.2 4500 919.8 920.1 4950 924.0 924.1 5034 924.7 924.8 5046 924.7 925.0 The DEM was revised to include a new, existing conditions cross-sections at river station 4250; this is the corrected effective model (CEM). Elevations for the new cross-section was determined using the topography provided for this project; the elevations were adjusted by 0.65 feet to match the datum of MEMORANDUM to the Town of Vinton March 5, 2021 Page 2 of 2 the existing flood model. The following table shows the difference between the DEM and CEM base flood elevations. Station DEM BFE, feet CEM BFE, feet 4048 919.5 919.5 4150 919.2 919.3 4250 - 919.6 4500 920.1 919.5 4950 924.1 924.1 5034 924.8 924.8 5046 925.0 925.0 Cross-sections 4150 and 4250 were adjusted for proposed improvements as shown in the plans Gish Mill Revitalization, Sheet L-101 and L-201, dated January 25, 2021; this is the proposed model (PCM). The following table shows the difference between the CEM and PM base flood elevations. Station CEM BFE, feet Proposed BFE, feet 4048 919.5 919.5 0.0 4150 919.3 919.3 0.0 4250 919.6 919.6 0.0 4500 919.5 919.5 0.0 4950 924.1 924.1 0.0 5034 924.8 924.8 0.0 5046 925.0 925.0 0.0 Therefore the proposed project, based in the information received, does not cause a rise in the base flood elevation.

Former Holdren’s County Store. •Topography/Vegetation –The existing structure is located adjacent to Glade Creek on a level lot that is comprised mostly of impervious surfaces. In relation to its special location, the Gish Mill, in serving its historic purposes, is located in the regulatory floodway and Special Flood Hazard Areas (SFHA) of the Glade Creek floodplain. •Site Access: The parcels can be accessed from Gus Nicks Boulevard and West Madison Avenue. •Adjacent Zoning and Land Uses: 5 Direction from Property Zoning District Land Use North N/A Glade Creek/ Roanoke City Parcel (RM-1) West MUD Apartment Building/ Future Business Flex Space Southeast M-1 Limited Industrial Clothing embroidery (Chalaine’s) and Sign Manufacturing (Sav’ On Signs) Businesses South N/A Right-of-way Planning and Zoning Department Adjacent Zoning and Land Uses 6 Planning and Zoning Department Regulatory Floodway and Special Flood Hazard Areas (SFHA) 7 Planning and Zoning Department No-Rise Certification •The Town utilized the consulting services of Draper Aden Associates to verify that the proposed redevelopment project would not cause a rise in the base flood elevation.The consultants were able to utilize the plans of the proposed improvements from the development team and implement them into the flood models.The conclusion of this H&H study was that the proposed project will not cause a rise in the base flood elevations. 8 Planning and Zoning Department Floodplain Variance Process (BZA) •The Gish Mill structure meets the definition of a “historic structure” set out in the definition section of Division 13, FO Floodplain Overlay District, of the Vinton Zoning Ordinance. Specifically, the Gish Mill structure meets the definition of subsection (a) pertaining to being “preliminary determined” for individual listing on the National Register. •Both the Town of Vinton and the Development Team understand that meeting this definition does not automatically exempt this project and its associated activities from the requirements of the floodplain ordinance. However, specific variances from the floodplain ordinance are being requested by the Town of Vinton with a public hearing of the Board of Zoning Appeals scheduled for March 30, 2021. 9 Planning and Zoning Department Current Conditions of Property 10 Planning and Zoning Department Current Conditions of Property Planning and Zoning Department11 Current Conditions of Property 12 Planning and Zoning Department Current Conditions of Property 13 Planning and Zoning Department Current Conditions of Property 14 Planning and Zoning Department Current Conditions of Property 15 Planning and Zoning Department Current Conditions of Property 16 Planning and Zoning Department Analysis of Proposed Redevelopment The Gish Mill Davii, LLC & Hill Studio, PC Presented by: Overview •The developer’s intended use for the mill site is to incorporate several value-added compatible uses,which launch from popular trends that work very well with the open format historic space.The building will be designed to feature several uses that take advantage of the creekside location,the unconventional construction methods,and varying dimensions and angles featured by the mill space.The specific uses include a small restaurant,a seasonal market,a speakeasy in the basement,and the conversion of the original mill structure, concrete silos,and upper floors of the original mill structure into lodging or apartments (3-10 units). •The anticipated tenant to operate the restaurant and lodge has already been secured for the project.The development also includes substantial outdoor spaces including dining,deck, and patio space.The historic “sluice”will be utilized as an intimate seating area with stairs that cascade down to the creek. 18 Square Footage of Uses •Based on the preliminary floor plans,the development will include: •(1)Restaurant (back of house,kitchen,and dining space):5,030 square feet (First floor) •(2)Market:1,250 square feet (First floor) •(3)Speakeasy:1,296 square feet (Basement) •(4)Original Mill and silos converted into lodging/apartments:5,800 square feet (Second and Third floor) •(5)Outdoor dining,deck and patio space:3,564 square feet (including the deck and patio area utilizing the existing slab) 19 Comprehensive Plan/Future Land Use •The 2004 –2024 Town Comprehensive Plan designates this property and the surrounding properties to the southeast as a general commercial land use area.The properties to the west of this property (across Gus Nicks Boulevard)are designated as parks and recreation,community facilities, and high density residential uses.The properties to the west were rezoned to Mixed Use Development (MUD)in 2016 to allow for the existing vacant school buildings to be adaptively reused as residential and recreational/small business flex space. 34 Planning and Zoning Department Specific Variances for Property/Project •Sec. 4-70 (c) (1): Non-Residential Construction Elevation Requirements (Freeboard Requirements) •“Non-residential construction. New construction or substantial improvement of any commercial, industrial, or non-residential building (or manufactured home) shall have the lowest floor, including basement, elevated to or above one foot above the base flood level. Buildings located in AE and AH zones may be flood-proofed in lieu of being elevated provided that all areas of the building components below the elevation corresponding to the base flood elevation plus one foot are water tight with walls substantially impermeable to the passage of water, and use structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy. A registered professional engineer or architect shall certify that the standards of this subsection are satisfied. Such certification, including the specific elevation (in relation to mean sea level) to which such structures are floodproofed, shall be maintained by the floodplain administrator.” 35 Planning and Zoning Department Specific Variances for Property/Project •Justification •Overall, the historic significance and nature of the identified areas of the structure warrant it being preserved and utilized with an adaptive reuse, which will preclude it from meeting this elevation requirement. •Proactive Measures being Undertaken: •A post-1955 addition appends the later 1940s addition mentioned above. This narrow, triangular addition stands on a concrete foundation. The form of this addition is dictated by the topography of the land and the trajectory of Glade Creek. The frame walls are covered with metal siding. The shed roof is covered with metal. The front elevation contains sliding metal freight doors. A small concrete dock extends from the front elevation of this addition. This non-historic component is actually being removed early in timeline of the project, and the existing concrete foundation will be utilized as a patio space for outdoor dining and leisure. •To the fullest extent possible, the electrical, heating, ventilation, plumbing, air conditioning equipment and other service facilities, including duct work, shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding. These service facilities will originate above the Design Flood Elevation (DFE) and will extend downward from the ceiling in such a way to keep them from being damaged during flood events. 36 Planning and Zoning Department Specific Variances for Property/Project •Proactive Measures being Undertaken (cont.): •Wet flood-proofing measures will be used for the building. Such measures allow for flood water to enter and exit the building. The strategy includes a series of vents that allow the movement of water through the building and decreasing the pressure on the existing walls. •The crawlspace area under the 1940s additions will not be used for storage or human inhabitation. •All sleeping quarters will be located well-above (2+ feet) above the base flood elevation within the structure. 37 Planning and Zoning Department Specific Variances for Property/Project •Sec. 4-71 (b) (2): Floodway Area: Special Use Requirement •“The following uses, types, and activities are permitted, provided that they are in compliance with the provisions of the underlying zoning district and are not prohibited by any other ordinance and provided that no specific land use requires any type of structure, fill, or storage of materials and equipment:…” 38 Planning and Zoning Department Specific Variances for Property/Project •Justification •The property is going through the rezoning process, which requires the approval of the Vinton Town Council. The nature of the floodplain requirements and the results of the hydrologic and hydraulic study (and attainment of the no-rise certificate) will be presented in full detail in all staff reports and presentation to both the Planning Commission and the Town Council. •Additionally, the documentation and studies to be presented to the Planning Commission and Town Council will already meet and/or exceed the requirements of the “procedures for special uses in the floodways.” As to not duplicate processes and hearings, in addition to the sufficiency of the information to be presented on at the briefings and work sessions, the special use requirement should not be required for this project. 39 Planning and Zoning Department Specific Variances for Property/Project •Sec. 4-72 (a): Existing structures in floodplain areas. •“A structure or use of a structure or premises which lawfully existed before the enactment of these provisions, but which is not in conformity with these provisions, may be continued subject to the following conditions: (a) Existing structures in the floodway area shall not be expanded or enlarged unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practices that the proposed expansion would not result in any increase in the base flood elevation.” 40 Planning and Zoning Department Specific Variances for Property/Project •Justification •As noted in the Section D above, 3,564 square feet of the redevelopment will be utilized for outdoor dining, deck and patio space (including a new deck and patio area located on the existing slab). The deck will not be structurally attached to the main structure in anyway; rather it will designed and constructed to resist the force of flood forces through exemplary anchoring techniques. Town staff and the development team understand that this deck will not be a coverable expense by a National Flood Insurance Program (NFIP) policy. Because of the crucial nature of the outdoor space to the financial feasibility of this project, and it being designed using the best contemporary architectural and engineering practices to resist flood forces, the deck and the utilization of the existing concrete slab shall be exempted from this requirement. •Proactive Measures being Undertaken: •The H&H study included these proposed improvements which demonstrates that is will not result in any increase in the base flood elevation. •The anchoring of the deck will utilize the historic sluice/race as its main foundational component. 41 Planning and Zoning Department Staff Conclusion •Staff recommendation: Approval/Granting of Variance(s) •Based on the information provided and the completion of critical studies (H&H study, attainment of no-rise certificate, etc.), Town staff find that this proposed redevelopment project meets the criterion of: •Showing of good and sufficient cause; and •Determination that failure to grant these variances will result in exception hardship and the ultimate loss of an important Historic structure that is preliminary determined for individual listing on the National Register by the Virginia Department of Historic Resources (DHR); and •Sufficiently presented, through engineering studies by engineering consultants, that granting these variances will not result in: •Unacceptable or prohibited increases in flood heights; •Additional threats to public safety; or •Extraordinary public expense; and will not: •Create nuisances; •Cause fraud or victimization of the public; or •Conflict with local laws or ordinances. 42 Planning and Zoning Department Questions?
