Merriconeag Sound in Harpswell lies in Casco Bay, adjacent to Potts Harbor. Harpswell is a coastal peninsula located nine miles south of Brunswick.
Tides and wave action in Merriconeag Sound caused severe erosion of the shoreline and endangered an historic 19th century cemetery in Harpswell, on the peninsula’s southern end. To strengthen the shore and protect the cemetery, the Corps constructed a 270-foot-long concrete seawall, having a maximum height of 10 feet and a minimum height of five feet.
The work in Merriconeag Sound was constructed under Section 14 of the Corps’ Continuing Authorities Program. It was built between August-December 1979 at a cost of $107,700.
