Great Lakes Dredge and Dock has begun landing pipes for the Town Neck (MA) beach area nourishment project.
In partnership with the Town of Sandwich and the Army Corps, GLDD will work to mitigate shore damage attributed to the east jetties of the Cape Cod Canal with a one-time placement of 320,300 cubic yards of sand on to Town Neck Beach.
The natural drift of sand through the littoral zone in this area of the Cape Cod Bay has been interrupted by the jetties, causing sand to accrete on the north side of the jetties. This sand would otherwise be destined for the Town Neck.
According to the Corps, this nourishment project will hydraulically dredge sand from a large borrow area off Scussett Beach, removing sand down to a depth of –18 Mean Low Low Water (MLLW), and convey it through a pipeline approximately 9,000 feet long across the bottom of the Cape Cod Canal up onto Town Neck Beach.
Once placed on the beach, the sand will be shaped according to an engineered design for a dune and berm system to prevent additional erosion.
Mobilization for the project is already underway and hydraulic pumping of sand onto the Town Neck beach is expected to begin this week.
