USACE proposes Hyannis Harbor Federal Navigation Project breakwater repair and maintenance work

The authorized FNP provides a stone breakwater extending southeast from the seaward end of the state breakwater on the western side of the outer harbor at Hyannisport; an anchorage area located behind (east) the Federal and state breakwaters at the southwestern end of the outer harbor;
a channel from Nantucket Sound through the outer harbor and Lewis Bay to the entrance of the inner harbor; a branch channel connecting the outer harbor anchorage with the entrance channel; a riprap jetty extending southward from Dunbar Point; an anchorage and turning basin located in the
eastern end of the inner harbor; a channel connecting the eastern and western ends of the inner harbor; and two anchorage areas located on the north and east sides of the eastern end of the inner harbor.

The purpose of the proposed project is to restore full functionality of the FNP breakwater to meet its authorized purpose and to extend the repairs made in the 1960s to enhance the durability of the structure using modern construction methods and practices.

The proposed work is being coordinated with the U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, National Marine Fisheries Service, Massachusetts Department of Environmental Protection, Massachusetts Office of Coastal Zone Management, Massachusetts Historical Commission, Massachusetts Board of Underwater Archaeological Resources, Hyannis Harbormaster, and the Mashpea Wampanoag and Wampanoag Tribe of Gay Head (Aquinnah) Native American tribes. An Environmental Assessment is in preparation and will be available for review upon request once complete.
