The parcel is bound by Elmer Street to the north and McCarrons Boulevard to the south. Currently, an unoccupied house and a garage exist on the southern portion of Mr. Guptil's property. A landlocked wetland, delineated as 0.93 acres, is located near the middle of the parcel. The existingproperty is approximately35% impervious, which includes the water surface area of the wetland as impervious. Proposed conditions will include the construction of condominiums to the north and south of the wetland. The developed property will be 63% impervious, which includes the water surface area of the wetland as impervious. Stormwater management will only be provided for 0.5 acres of the site and will consist of a detention pond in the southeast comer of the development. It appears that runoff from the detention basin will be routed by pipe to existing storm sewer within McCarrons Boulevard. Runoff from 0.198 acres of the site will discharge directly to Elmer Street, 0.175 acres of the site will discharge directly to McCarrons Boulevard, and the remaining 1.757 acres will discharge directly to the onsite wetland.
