USACE to dredge Long Island Intracoastal Waterway

The U.S. Army Corps of Engineers, New York District recently presented plans for the maintenance dredging of the Long Island Intracoastal Waterway Federal Navigation Channel (LIIW).

According to the Corps, the work will involve dredging of the Long Island Intracoastal Waterway in Quogue Canal in Suffolk County, New York

LIIW was last dredged in 2023 by a cutterhead dredge, with the removal of 18,900 cubic yards of sand from Moriches Bay and placement of dredged material on the ocean shoreline of Cupsogue Beach County Park and Smith Point County Park.

This dredging campaign will remove approximately 50,000 CY of sand from the LIIW to a depth of -6 feet MLLW plus two (2) feet allowable overdepth. The proposed work will dredge four sandy shoals within LIIW at Quogue Canal and Shinnecock Bay.
