The uses within the commercial spaces will be determined by the market. Potential uses include a mix of restaurants, retail, and professional services. The interior layout, size, and exact footprints of the commercial tenant spaces will also be determined by the market, while meeting the requirements of the form based code. SITE: The buildings will be constructed on Lot B within South Burlington’s form based code City Center zoning district. Lot B is bisected by the T-4 & T-5 transects. The site is located east of Market Street, north of Garden Street, and south of the future street providing access to the City Hall / Library and Marcotte Central School. Existing apartment buildings are located across Garden Street to the south. An undeveloped parcel is located across Market Street to the west. An apartment building is under construction to the southwest as the intersection of Market Street and Garden Street. City Hall, the library, and senior center are located to the north. To the east is the Marcotte Central School, with the athletic fields closest to the project site. CONSTRUCTION PHASING: Construction of the three buildings will be staggered over about 18 months. The following outlines the proposed start of construction and occupancy dates: Catamount Run – Lot B Proposed Commencement of Construction & Occupancy Building Commencement Occupancy B1 March 2023 July 2024 B2 March 2023 July 2024 B3 June 2023 May 2024 PARKING: Shared surface parking for the three buildings will be provided within the interior of the block. Parking spaces in the garages will likely be assigned to residents. In addition, on-street parking will be available along Market Street and Garden Street. A total of 234 parking spaces are proposed for 162 dwelling units and less than 20,000 square feet of commercial tenant space. The proposed parking is less than the maximum of 2 spaces per dwelling unit. There is no minimum parking demand for the commercial uses. The commercial uses will likely be focused on serving City Center residents, reducing their parking demand. Short term bike parking is provided along Market Street and adjacent to the parking area for Buildings B1 & B2. Short term bike parking is located adjacent to the surface parking for Building B3. Long term bike parking is provided in the parking garage for Buildings B1 & B2. Bike parking will be located at the front of the vehicle parking spaces, as well as common areas within the garage. A vertical bike rack will be wall mounted, staggered between vehicle parking spaces (the vehicle space and bike space will be assigned to the same resident). The balance of the long term bike spaces will be provided in common areas using vertical wall mounted racks. Long term bike parking for Building B3 will be provided within the building. OPEN SPACE: The open space requirement will be met using a combination of onsite and offsite open space elements. The Large Development Area open space credit utilizing the City Stormwater Park located off Market Street will be used to meet 50% of the open space requirement. The balance of the required open space will be met with a rain garden, pocket plaza, garden space, and a snippet/parklet (see the Open Space narrative for additional details). INCLUSIONARY / AFFORDABLE HOUSING: Miscellaneous Application #MS 18-05 established compliance with inclusionary zoning requirements for current and future residential development within the Covered Development, which includes Lot B. The proposed buildings involves construction of 161 market rate dwelling units. Inclusionary housing units are not required for this application, based upon the findings for the Covered Development in the Miscellaneous Application approval. As required by conditions 10, 11, & 13 of the approval, an updated summary of the inclusionary and market rate units including this application is attached. WATER & WASTEWATER FLOWS: The following summarizes the water and wastewater design flows for the residential portion of the project. The design flows for the commercial uses will be determined once the uses are known.
