PHASE 2 OF DREDGING OF COTUIT BAY ENTRANCE CHANNEL AND WESTERN TIP OF SAMPSON’S ISLAND
The Department of Public Works, in collaboration with Barnstable Clean Water Coalition, Massachusetts Audubon Society, and Barnstable County, will begin operations for Phase 2 of the dredging of the Cotuit Bay Entrance Channel and the western tip of Sampson’s Island during the week of October 15, 2019.
Dredging is anticipated to commence on or about October 30th. This work is a continuation of the work completed last year and will widen the existing channel by approximately an additional 130 feet. The dredged material will be utilized for beach nourishment purposes on the southern side of the eastern end of the island and for a habitat enhancement area.
