Project purpose: Shore protection, habitat enhancement and maintain spit feature that protects cove area in lee.

The site has a long fetch exposure to the southeast down the Potomac River and across the Bay of over 35 miles. Breakwaters with beach fill and a sill, which cover 800 ft of shore, were installed in 1989. The project consists of 3 headland breakwaters, beach fill and wetlands plantings along the Potomac River shore and a low sill on the back side on the Yeocomico River side to protect the spit. It was designed utilizing the 1:1.65 ratio of Bay indentation to Bay Gap relationship (Mb:Gb). The site has an open boundary on updrift project end and a breakwater spur on the distal end of the spit.
