The U.S. Army Corps of Engineers, New York District, together with the contractor Donjon Marine Co., recently completed the Flushing Bay and Creek Federal Navigation Channel Maintenance Dredging Project.
The $10.1 million worth contract included removal of approximately 135,000 cubic yards of dredged material in order to return the channel to its authorized depth of 15 feet.
The material dredged during the works – a mixture of sand, silt, and clay – has been beneficially reused for placement at an upland site in Sayreville, NJ.
A closed environmental clamshell bucket, shown on the photo, was used during the dredging project to ensure compliance with the State-issued Water Quality Certification.
The Flushing Bay Federal Channel supports 14 marine terminals that receive and ship sand, stone and petroleum products by barge, with approximately 1,425,000 tons of cargo transported through the channel annually.
