Maintenance dredging of two anchorages and a portion of the entrance channel of the York Harbor Federal Navigation Project in York, Maine, will be completed under the terms of a $1.7 million contract, recently issued by the U.S. Army Corps of Engineers, New England District.
Work will be accomplished by Prock Marine Company of Rockland, Maine. Once a notice to proceed is issued dredging will be authorized to start.
Dredging is scheduled to take several months to complete.
The proposed work consists of the mechanical maintenance dredging to remove shoals in the two, 8-foot-deep anchorages and a portion of the 10-foot-deep entrance channel.
Approximately 90 percent of the anchorages have shoaled in, USACE said in their release.
This project consists of the maintenance dredging of approximately 40,000 cubic yards of primarily fine-grain sand, silt and clay, with more coarse grain sand and gravel from the channel, returning the Federal project to its authorized dimensions.
The dredged material will be placed at the Cape Arundel Disposal Site, about 14 miles away. The dredge window, due to environmental constraints, is November 1 to March 31.
The last time the harbor was dredged was in 1996 when approximately 48,000 cubic yards of sediment were mechanically removed from the two anchorages, and placed at the Cape Arundel Disposal Site.
