Donjon Marine Wins Old Saybrook Dredging Contract

Maintenance dredging of the North Cove Federal Navigation Project in Old Saybrook, Connecticut, will be completed under the terms of a $4.2 million contract recently awarded by the U.S. Army Corps of Engineers, New England District.

Work will be accomplished by Donjon Marine Company, Inc. of Hillside, New Jersey.

Dredging is scheduled to start in the fall of 2017 and take about 3-4 months to complete.

“Approximately 286,000 cubic yards of predominantly silty sediment will be removed by mechanical dredge from the 11-foot deep entrance channel, 11-foot deep anchorage and 6-foot deep anchorage,” said Project Manager Craig Martin, of the Corps’ New England District, Programs and Project Management Division in Concord, Mass.

“With the extensive number of shallow draft projects nationwide competing for limited Federal funding, this maintenance event would not have been possible without the financial support of the state of Connecticut and commitment of its Port Authority to make it happen,” Martin said.

The state of Connecticut bonded $7.5 million in 2015 for the permitting, design and construction of the maintenance dredging project.

Silty shoal material removed from the cove will be placed in dump scows and hauled approximately 35 miles southwest by water route to the Central Long Island Sound Disposal Site and placed at predesignated coordinates, according to USACE.

All dredging operations in the entrance channel and 11-foot anchorage will occur between October 1, 2017 and January 31, 2018 to minimize impact to natural resources in the area. All dredging operations in the 6-foot anchorage will occur between October 1, 2017 and March 31, 2018 to minimize impact to natural resources in the area, said USACE.
