Burlington, VT 05403 Engineer Krebs & Lansing Consulting Engineers 164 Main Street Colchester, VT 05446 Property Information Tax Parcel 2000‐0000_C Airport‐Industrial (AIR‐I) District 777.84 acres Architect Weimann Lamphere Architects 525 Hercules Drive Colchester, VT 05446 Location Map #SD‐20‐12 Staff Comments 2 2 of 4 PROJECT DESCRIPTION Sketch plan application #SD‐20‐12 of Heritage Aviation, Inc. to amend a previously approved plan for an airport complex. The amendment consists of constructing a 24,674 sq. ft. addition to an existing 17,660 sq. ft. hangar, reconfiguring the adjacent parking area, and related site improvements, 1130 Airport Drive. PERMIT HISTORY The Project is located in the Airport‐Industrial (AIR‐I) district. The project received approval to construct the current hangar in 2004. COMMENTS Development Review Planner Marla Keene and Planning and Zoning Director Paul Conner (“Staff”) have reviewed the plans submitted on 3/6/2020 and offer the following comments. Numbered items for the Board’s attention are in red. CONTEXT The Project is located in the Airport‐Industrial District (AIR‐I), the Transit Overlay District, and the Traffic Overlay District. All applications for development within the AIR‐I district must be reviewed pursuant to the site plan provisions of Article 14 unless the PUD or subdivision provisions control. ZONING DISTRICT & DIMENSIONAL REQUIREMENTS Dimensional Requirements The applicant has represented that the proposed facility will result in a slight decrease to overall lot coverage to the airport PUD as a whole, which the applicant estimates to be 34%. The maximum allowable lot coverage for this district is 50%. The applicant has not provided an estimate of building coverage for existing or proposed conditions. The maximum allowable building coverage for this district is 30%. Staff considers it unlikely the building coverage exceeds the maximum allowable. 1. Historically, the Board has allowed the airport to provide estimated coverage calculations as long as it is demonstrably well within the allowable maximums due to the overall size of the property. Staff recommends the Board discuss whether they would like the applicant to provide existing and proposed building coverages. The applicant notes the apex of the roof of the proposed addition is 35’‐11” above preconstruction grade. The allowable height limit for pitched roofs in this district is 40‐ft, but the roof is only proposed to have a 1 on 12 slope, which Staff considers to be effectively a flat roof. Therefore the maximum height limit should be considered to be 35‐ft based on a flat roof. However because of the size of the building, even with the relatively flat roof, the height at the edge of the two‐story addition is 30’‐8” above preconstruction grade, resulting in a measurement at the midpoint of the roof lower than the maximum allowable height of 35‐feet. Section 3.07D(2) also allows the Board to grant a height waiver in the case of increased setbacks. For each 1‐ft of additional height, front setbacks are increased 1‐ft and side by 0.5‐ft. #SD‐20‐12 Staff Comments 3 3 of 4 2. Staff recommends the Board discuss how they will calculate height for the purpose of this application. Other dimensional requirements appear to be met. Airport‐Industrial (AIR‐I) District Additional Standards The district’s standards relate to electrical interference, light and glare, physical obstruction to airport approaches and compliance with Federal Aviation Administration and other federal and state regulations pertaining to airports. Staff considers that the applicant will need to provide documentation of compliance from the applicable regulatory entities responsible for airport approach cones as part of their final plat application. SITE PLAN REVIEW STANDARDS General site plan review standards relate to relationship to the Comprehensive Plan, relationship of structures to the site (including location and adequacy of parking), compatibility with adjoining buildings and the adjoining area. Specific standards speak to access, utilities, roadways, and site features. Relationship of Proposed Structures to the Site The applicant has described the project as follows. No change in use is proposed. Heritage Aviation is proposing to construct an addition to their existing hangar facility to expand their aircraft and ground support equipment maintenance program. The expanded building will primarily replace the existing paved parking area on the west side of the existing hangar. The front façade of the building has been designed to add character to the existing facility and to promote the building’s front entrance. 3. Staff recommends the Board invite the applicant to described the proposed aesthetics of the building, as shown in the provided elevation drawing, and discuss whether the project appears to meet the requirements that structures be related harmoniously to themselves, the terrain and to existing buildings and roads in the vicinity that have a visual relationship to the proposed structures. The applicant is encouraged to use a combination of materials, architectural characteristics, landscaping, buffers, screens and visual interruptions to meet this requirement. Access to Abutting Properties The building proposed as part of this application serves as a portion of the security fence around the airport, and it continuous with the fence on the north and west sides. Staff considers that because of this limitation, the requirements for access to abutting properties do not apply. Utility Services The property is currently served by a mixture of above and underground utility services. The applicant is proposing to retain the mix, including the fixtures served by the aboveground utilities. 4. Staff recommends the Board discuss whether this application warrants requiring those utilities to be located underground. Landscaping and Screening The project will require landscaping based on the building construction cost. The airport is presenting an #SD‐20‐12 Staff Comments 4 4 of 4 overall airport landscaping plan to the Board on May 5, 2020. The intent of that landscaping plan is to provide pre‐approved locations for landscaping beyond that which is required for screening and buffering on individual project sites. 5. Staff recommends the Board ask the applicant to discuss their intended landscaping and what proportion of the required minimum landscaping budget they anticipate locating on site vs in areas identified in the overall airport landscaping plan. 6. Staff further recommends the Board discuss for what, if any, portion of the parking lot they will require the applicant to comply with minimum interior landscaping and shade tree requirements. Low Impact Development The Stormwater Section has reviewed the plans on April 6, 2020 and offers the following comments: 1. This project is located in the Potash Brook watershed. This watershed is listed as stormwater impaired by the State of Vermont Department of Environmental Conservation (DEC). 2. The Stormwater Memo references a HydroCAD model, which was not included. In a future application, please include the HydroCAD model for review. 3. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure. PLANNED UNIT DEVELOPMENT STANDARDS PUD standards pertain to water and wastewater capacity, natural resource protection, compatibility with the surrounding area, open space, fire protection, and public infrastructure. Utility Lines The project will require relocation of the existing water, gas and electric lines serving the building. Staff notes the project will require review by the South Burlington Water Department, and further notes that the Fire Chief has indicated building safety requirements will require modification of the interior fire supression system for the building. RECOMMENDATION Staff recommends that the Board discuss the Project with the applicant and close the meeting.
