According to the Corps, the areas of consideration for these dredging services are Wilmington Harbor Anchorage Basin and 42-Ft Project, New Hanover and Brunswick Counties.

The Wilmington Harbor project includes maintenance dredging of upper Wilmington Harbor federal navigation channel reaches including the Anchorage Basin and Turning Basin Extension.

The work will consist of removal and disposal of shoaled material that has accumulated in the channels and berth areas since the various areas were last dredged. The estimated quantity of material to be dredged is 1.5 to 2 million cubic yards.

The second project includes maintenance dredging of middle Wilmington Harbor federal navigation channels from Upper Brunswick to Battery Island.

The work will require a mechanical dredge and ocean certified barges to transport 400K to 800K cubic yards of dredge material to the disposal site.

Dredging depths are 42’ plus 2’ of allowable overdepth for all reaches except Battery Island, which has a dredging depth of 44’ plus 2’ of allowable overdepth.

The environmental window for dredging the Wilmington Harbor federal navigation channel reaches is 1 August through 31 January.
