USA: Army Corps Seeks Contractors for Clinton Harbor Channel Dredging
The U.S. Army Corps of Engineers, New England District, is soliciting small business contractors for the Maintenance Dredging of the 8 ft Federal Navigation Channel into Clinton Harbor, in the town of Clinton, CT.
The work of this project consists of maintenance dredging approximately 45,000 cubic yards (CY), of predominantly sandy sediment, by hydraulic dredge from the Clinton Harbor 8-ft navigation channel. The channel is 100 feet wide, about 1.1 miles in length, and extends from Long Island Sound into Clinton Harbor, Clinton, CT.
The sandy dredge material will be pumped via pipeline to Hammonasset Beach State Park in Madison, CT about 1.8 miles away to the west.
Of the 45,000 CY of maintenance dredging, approximately 30,000 CY will be required to dredge down to -8 ft Mean Lower Low Water (MLLW), and another 15,000 CY of 1-ft allowable overdepth to -9 ft MLLW. All dredging operations will occur between October 1, 2012 and March 31, 2013 to minimize impact to natural resources in the area.
A major emphasis in the dredging project is removal of the tip of Cedar Island which has migrated into the channel, making navigation safety a concern for the Clinton maritime community.
The work will not include dredging 2 small anchorages and a portion of the channel north of Cedar Island where material is too silty to be placed at Hammonasset Beach State Park.
