Task 1. Draft and finalize a Site Specific Project Plan (SSPP)Prepare a draft SSPP for pollutant load reduction modeling to document BMP-specific pollutant load reductions as Best Management Practices are installed.Revise as required by DES and secure final approval from DES. Task 2 Design and implement the following stormwater improvements Site 1: Abenaukee Drive at Route 28 A series of catch basins collect runoff from the intersection of Abenaukee Drive and Route 28. One of the catch basins in the series collects runoff from the area of Abenaukee Drive and Route 28 (target area for BMP). In addition to this storm drain system, a wetland west of Route 28 also drains through the culvert under Route 28 via an unstabilized channel that contributes sediments to the inlet and pond. A flow splitter and hydrodynamic separator installation are proposed as well as stabilization of the existing headwall and stabilization of thirty linear feet of channel with a combination of soil encapsulated lifts and natural stone.Site 2: North side of Route 28 and Cross Road Runoff from Route 28 and Cross Road enters a series of catch basins that discharge to an unstable ditch along the north side of Cross Road. The ditch outlets into a culvert and then to the wetland area discussed under Site 4. Installation of a sediment trap at the outlet of the terminal catch basin in that would be 50 feet long by 4 feet wide. The sediment trap will capture suspended solids from road runoff and allow it to be removed by the DPW. Stabilization of approximately 50 feet of the ditch will also occur with erosion control blanket and vegetation to eliminate erosion.
