4 Affordable Housing Trust Minutes June 25, 2018 Discussion of Affordable Housing Feasibility Study (Phase 2) at 950 Falmouth Road; (continued) A summary of the Development Feasibility Study dated April 2018 details the design item options. However, further discussions are required, and the items should not be construed as final design. Typical scenarios as noted; Building types include; 2-Story Building 43 Residential Units 1.9 Spaces per Unit 3-Story Building 69 Residential Units 1.2 Spaces per Unit 2-2 '/2 Story Building 23 ----41 Residential Units 1.25-2.2 Spaces per Unit (up/down townhouse unix) 68—2 Bedroom Units Total Units: 34 69— 3 Bedroom Units Total Units: 23 68 —Mixed Bedroom Units Total Units: 29 Discussion followed with respect to the buffer between the Southcape Resort and the proposed affordable housing development. It was recommended that a naturally vegetative buffer of equal distance remain to reduce the visibility to protect the abutting Southcape Resort. Currently, the proposed buffer is 20' off the property line, 10' at its thinnest. The townhouse concept maintains a 15' buffer at its narrowest point. Upon review and consideration, the project engineer indicated that Parcel B could move forward to create an improve buffer for the Southcape residents. It was agreed the existing vegetation would be retained and enhanced with additional trees for increased visual improvement. Due to height and topography most of the structures would be visible. In terms of wastewater, Title V is required to permit the proposed development in a nitrogen sensitive area. The maximum allowable wastewater flow outlined in the preliminary feasibility study was determined to be 6,980 gallons per day (gpd) using the 550 rule under Title V regulations. The loading rate of 550 gpd per acre is applied to the total combined site acreage for all 3 lots including the stream area. Title V defines a building acre as 40,000 square feet, not 43,560 sf. Nitrogen Aggregation of Flows; Total Lot Area: 12.83 acres Building Acres: 13.85 acres Allowable Flow (gpd) 6,980 7,600 There was concern as the watershed is over compliance and the project does not comply with the no nitrogen rule. Other than Title V, the project does not include any advanced technology solutions or connection proposals with existing treatment plants to maintain zero nitrogen. It was suggested the project engineer consult the abutters, possibly the Southcape Resort to partner in wastewater treatment. It was agreed a shared system is a viable option. Mr. Kuchar was requested to calculate the number of bedrooms required in terms of flow to maintain zero nitrogen.
