Planning & Zoning Department 180 Market Street South Burlington, VT 05403 RE: Site Plan Amendment Application #SP-22-060 – 224 & 268 Market Street and 339 Garden Street Dear Marla: We are writing to request Site Plan Amendment approval for the reconfiguration of the dwelling units within the three buildings under construction on Lot B at City Center. Only changes to the interior layout of the residential dwellings in Buildings B1 & B2 are proposed. Modifications to the lobby entrance of Building B3 and related façade changes are also proposed. Building B1 (268 Market Street), Building B2 (224 Market Street), and Building B3 (339 Garden Street) were all previously approved under Site Plan application #SP-22-060. The table below summarizes the previously approved and proposed number of dwelling units and bedrooms in Buildings B1, B2, & B3: Building B1 – 268 Market Street Previously approved Proposed Amendment 1 bedroom dwelling units 33 DU 27 DU 2 bedroom dwelling units 40 DU 19 DU 3 bedroom dwelling units 0 DU 18 DU TOTAL 73 DU (113 bedrooms) 64 DU (119 bedrooms) Building B2 – 224 Market Street Previously approved Proposed Amendment 1 bedroom dwelling units 27 DU 21 DU 2 bedroom dwelling units 35 DU 14 DU 3 bedroom dwelling units 0 DU 18 DU TOTAL 62 DU (97 bedrooms) 53 DU (103 bedrooms) Building B3 – 339 Garden Street Previously approved Proposed Amendment 1 bedroom dwelling units 13 DU 1 DU 2 bedroom dwelling units 13 DU 19 DU 3 bedroom dwelling units 0 DU 0 DU TOTAL 26 DU (39 bedrooms) 20 DU (39 bedrooms) Although there is a decrease in the number of dwelling units, the total number of bedrooms will increase in Buildings B1 & B2. The number of bedrooms in Building B3 will remain the same. The non-residential spaces on the first story of Buildings B1 & B2 shown on the latest floor plans are summarized below: Non-Residential Space Previously approved Proposed Amendment Building B1 268 Market Street 11,322 sf 14,350 sf Building B2 224 Market Street 11,353 sf 13,350 sf TOTAL 22,675 sf 27,700 sf Architectural plans Buildings B1 & B2 The building footprint and elevations are unchanged from the previously approved plans. The door spacing and windows on the first story (street level) have not changed. The window sizes and arrangement on the upper floors have also not changed. Similarly, the building materials, building breaks, and other elements of the building façade are unchanged from the previously approved plans. Building B3 The reconfiguration of the dwelling unit layout involved adjusting the location of the lobby entrance off Market Street. Shifting the lobby entrance affects the façade and window arrangement. The architectural plans have been updated accordingly, along with the exhibits demonstrating compliance with the building breaks, entrances, and glazing requirements. In addition to eliminating the basement, there have also been minor changes to the non-regulated facades. A one story electrical room has been added on the rear façade at the east end of the building. A one story mechanical room has been added at the rear of the building adjacent to the lobby entry from the parking lot. Civil Plans The Overall Site Plan has been updated to reflect the change in the number of dwelling units in each building, along with the maximum vehicle parking, required bike parking, and open space. Although the minimum required parking and open space have changed, there have been no changes to what was previously approved. The civil plans have been updated to reflect the changes to the building footprint and entrance locations of Building B3. The modified entrances required that accessible ramps at the front and rear of the building be reconfigured. The water services have also been adjusted to reflect the elimination of the basement and addition of a first story mechanical room. Civil sheets 3, 4, 6, & 10 reflect these changes. Landscaping Plans The landscaping plans have been updated to reflect the changes to the walkways and ramps at Building B3. While plant groupings and locations have been modified, the total value of plantings previously approved has not changed. Accordingly, the landscape budget remains unchanged. Inclusionary zoning Buildings B1, B2, & B3 will have all market rate dwelling units. Inclusionary housing units are not required in this building, based on the findings for the Covered Development in Miscellaneous Application #MS 18-05. The summary of the inclusionary and market rate units has been updated for the Covered Development. Wastewater allocation Since the number of dwelling units will decrease in each of the three buildings, there is also a decrease in the wastewater allocation required. Wastewater allocation was previously purchased at the time of zoning permit issuance for the previously approved number of dwelling units in each building. Water allocation Additional water allocation is needed for the increase in the number of bedrooms in Buildings B1 & B2. No additional water allocation is needed for Building B3. Requests for additional water allocation have been submitted to the Water Department. Trip Generation No change in the total trip generation is proposed from the three buildings. Although the reduction in the number of dwelling units results in a slight reduction in the estimated trip generation using the ITE Trip Generation Manual, the commercial uses have been modified such that there is no change in the total estimated trip generation. The total area of the non-residential spaces have been revised to match the current layouts in Buildings B1 & B2. An updated spreadsheet is enclosed with the estimated trip generation for both the residential and non-residential uses. Note that the commercial uses are subject to change based on the actual tenants. Parking There are no changes proposed to the previously approved garage in the basement level of Buildings B1 or B2, or the surface parking. A total of 236 parking spaces are proposed (garage & surface spaces). With 137 total dwelling units in Buildings B1, B2, & B3, there is 1.72 parking spaces per dwelling unit, which is less than the allowable maximum of 2 spaces per unit permitted in the Land Development Regulations. Bike Parking Although the number of bike spaces required decreases with the reduction in dwelling units, there are no changes proposed to the previously approved short term or long term bike spaces. The bike racks around the perimeter of the building and within the parking garage are unchanged from the previously approved plans. Open Space The open space area required by LDR Section 8.08 is based upon the number of dwelling units. Since the number of dwelling units proposed will decrease, there will also be a corresponding decrease in the required open space area. However, no changes are proposed to the previously approved open space areas. The total open space provided does decrease slightly, since the Large Development Area credit is limited to 50% of the required open space for a building. Landscaping budget No changes to the previously open space areas are proposed. Although minor adjustments have been made to the plant groupings and locations around Building B3, the overall planting plan remains substantially the same. Therefore, there are no changes to the previously approved landscape budget. Please let us know if you have any questions on this amendment application. Sincerely, Andrew Rowe
