The revision includes the addition of sediment and re-contouring to level the ground between 66A River Street and the abutting property to the north, 258A Pleasant Street. Refer to the revised Restoration Plan submitted with this letter for the location of the proposed work. A low point between the properties forms a swale that channelizes and speeds up storm-water run off towards Bass River. The proposed actions would ameliorate the channelization of storm-water by spreading the flow over more level ground and slow the storm-water velocity to allow for infiltration into the root zone of the native plant before reaching Bass River. Please note that this proposal is not to create a rain garden as the re-contouring would create a flat area, not a depression as is typical of rain gardens.
