The U.S. Army Corps of Engineers, New England District, recently awarded a $1.6 million contract to Coastline Consulting and Development for maintenance dredging of the Cape Porpoise Harbor in Kennebunkport, Maine.
Under the deal, the contractor will remove around 25,000 cubic yards of primarily fine- and medium-grain sand, and silt from approximately 12 acres of the authorized project area.
According to USACE, Coastline Consulting will use a mechanical dredge and scows to remove the material and then transport it for placement at the Cape Arundel Disposal Site or the Portland Disposal Site.
Construction is expected to take between 1-3 months within the allowable dredge window of Nov. 1 to March 15. The work is anticipated to be performed in 2019/2020.
The Corps’ most recent dredging of the harbor was in 1976 when a mechanical dredge removed approximately 123,000 cubic yards of sediment from the 15-foot channel, 15-foot anchorage, and 6-foot channel, and placed the material at the Cape Arundel Disposal Site.
