Maintenance Dredging, New Havan Harbor, Connecticut
Navigational maintenance project in New Haven Harbor, New Haven County, Connecticut, consists of dredging in the main channel, from Long Island Sound to the Tomlinson Bridge, to its authorized depth of 35 feet and disposal of an estimated 800,000 cubic yards of spoil material. The sediments to be dredged are classified as organic silt on the shoreward side of the breakwaters and more granular (gray or brownish) silty-sand to the seaward side. Test results of the spoil reveal the presence of relatively high concentrations of zinc, lead and copper. Plans call for the dredge spoil to be deposited in the New Haven Dump Grounds. The project as the term 'maintenance' implies will restore the Federal shipping channel to its authorized dimension, thereby alleviating existing shoaling problems. The maintenance dredging will also serve to reduce or eliminate the costly tidal delays currently experienced as a result of the shoaling. Overall, the action will insure continued safe ship passage and subsequent viability of local economy dependent upon harbor's resources. Adverse environmental effects are those associated with dredging and ocean deposit of spoils.
