The U.S. Army Corps of Engineers New England District has awarded a contract for maintenance dredging of Cape Porpoise Harbor Federal navigation project in Kennebunkport, Maine. The $1,677,500.00 contract was awarded to Coastline Consulting and Development, LLC of Branford, Connecticut on August 19.
Approximately 30,000 cubic yards of sandy and fine-grained material will be dredged from the 6-foot channel and 15-foot anchorage and channel and placed at Cape Arundel Disposal Site, located about 5 nautical miles from the harbor.
The dredging operation is scheduled to begin in November and finish in February 2020.
Natural shoaling processes have reduced available depths to as little as 1 foot in the 15-foot MLLW channel and anchorage, and 2 feet in the 6-foot MLLW channel, making navigation hazardous or impossible at lower stages of the tide.
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, placing the material at the Cape Arundel Disposal Site.
