USACE Proposes Enders Island Shoreline Erosion Protection Project

The U.S. Army Corps of Engineers, New England District, is proposing a shoreline erosion protection project on Enders Island in Stonington, Conn.

A masonry seawall protects the Enders Island facility (St. Edmund’s Retreat) and associated property and facilities from storms, but the wall is currently in poor condition, especially on the southeast side, USACE said.

The purpose of the proposed project is to stabilize the existing seawall and prevent further erosion of the island behind the seawall.

“Public comments on this proposed project for shoreline erosion protection at Enders Island should be forwarded no later than Aug. 6, 2017 to the U.S. Army Corps of Engineers, New England District,” USACE said in its release.

Waves have damaged the existing seawall during storm events and have, on occasion, overtopped the wall, causing erosion on the landward side. The erosion threatens the stability of the wall and function of the septic system serving St. Edmund’s Retreat.

Without permanent protection of the seawall, the landward property will continue to erode, the septic system will cease to function properly and the wall will collapse. Once the wall collapses, the entire island will be exposed to eroding wave energy and will cease to function as a retreat and public passive recreation area, USACE said.

The plan proposed for the shore protection for Enders Island is a stone revetment approximately 30 feet wide (including toe), 8 feet tall and extending approximately 700 linear feet along the east and southern portion of the seawall.

The revetment along the toe of the existing wall will consist of two benches, a 12 foot wide bench (including sloped section) with a height of approximately 2.3 feet mean low water (MLW) with a 6-foot wide crest and a 17-foot wide upper bench forming the top of the revetment at approximately 8 feet MLW with a 10-foot wide crest.

This tiered revetment will require approximately 260 cubic yards of crushed stone and 4,400 cubic yards of 2,000 to 3,000 pound armor stone.
