GREAT LAKES BEGINS MAINTENANCE WORK AT BALTIMORE HARBOR

Great Lakes Dredge and Dock began a maintenance dredging project at Baltimore Harbor channels. Under contract with the Corps of Engineers Baltimore District the contractor will remove 1 million cubic yards. The $14.1 million contract was awarded last fall. Great Lakes began dredging in February.

The following channels associated with the Port of Baltimore will be dredged to their respective authorized dimensions plus specified allowable overdepths ranging from one to two feet:

• Brewerton Angle to a depth of 51 feet and width of 700 feet (roughly 540000 cubic yards);

• Craighill Angle to a depth of 51 feet and width of 700 feet (roughly 460000 cubic yards);

• Ferry Bar to a depth of 42 feet and width of 600 feet (roughly 73000 cubic yards).

In coordination with the State of Maryland the roughly 500000 cubic yards of material dredged from Craighill Angle will be beneficially reused at the Paul S. Sarbanes Ecosystem Restoration Project at Poplar Island located on the eastern side of the Chesapeake Bay. Also in coordination with the State of Maryland the roughly 540000 cubic yards of material dredged from Brewerton Angle will be placed at the Cox Creek Dredge Material Containment Facility (DMCF) and the material removed from Ferry Bar will be placed at a Confined Aquatic Disposal Cell located adjacent to the Masonville DMCF.
