The city of Meriden is seeking a permit from the U.S. Army Corps of Engineers, New England District to conduct work in waters of the United States in conjunction with activities to reduce flood risk in downtown Meriden, Conn.
The proposed work by the city of Meriden includes excavation and the discharge of excavated and fill material into Harbor Brook for the purpose of flood risk reduction for the city of Meriden downtown area through the relocation of compensatory flood storage generally consistent with the one percent chance flood event to other locations within the Harbor Brook watershed, while ensuring there is no increase in peak flood flow downstream of Hanover Pond.
The project is proposed to take place in three phases from 2012 to 2021. The work is proposed in Harbor Brook between Hanover Pond and Baldwin Pond in Meriden.
The city of Meriden proposes to modify approximately 3.4-miles of Harbor Brook, resulting in 8.83 acres of permanent impacts below the ordinary high water mark and 1,323 square feet of permanent impacts and 783 square feet of temporary impacts to federal wetlands. These permanent and temporary impacts will result from a range of activities including creation of floodplain shelves; regrading the stream bed channel and associated bank grading; reestablishment of a low-flow channel; accumulated sediment removal; bank stabilization with coir logging; placement of rip rap; multiple bridge removal and replacements to accommodate the new proposed base flow; removal of retaining walls; day lighting 3.2 acres of piped stream; culvert, manhole and outfall installation; energy dissipater, sediment trap, dewatering pump and access road construction; and construction of a linear multi-use trail along the entire length of Harbor Brook.
