Island Avenue is located along the west side of Great Hill in the Houghs Neck section of Quincy.
Shoreline erosion had created a steep bluff at the edge of Island Avenue, adjacent to the shoreline. The eroded area, about 45 feet high and 300 feet long, endangered both Island Avenue and the main sewer line at the nearby Nut Island Wastewater Treatment Plant. In response to this problem, the Corps built about 265 feet of stone slope protection along Quincy Bay.
Built between August 1982 and June 1983, Island Avenue was constructed under Section 14 of the Corps’ Continuing Authorities Program. It cost $172,000.
