USA: RC & D Wins Riverbank Protection Deal

Construction of a project for emergency streambank protection along the Connecticut River in Middletown, Conn., will be completed under the terms of a $1,282,550.00 contract recently awarded by the U.S. Army Corps of Engineers, New England District.

The construction will be conducted during the Connecticut River seasonal low flow period in the wet. Work will be accomplished by RC & D, Inc. of Providence, Rhode Island.

“The work consists of stabilizing approximately 1,300 feet of riverbank along the right bank of the Connecticut River in Middletown adjacent to the John S. Roth Municipal Well Field on River Road,” said Project Manager Robert Russo, of the Corps’ New England District, Engineering and Planning Division, in Concord, Mass. “The work is required to stabilize the shoreline and prevent further erosion of the riverbank, which has threatened the city’s well field and public water supply.”

In order to reduce construction sedimentation from entering the river, the contractor will employ a floating silt curtain. The construction will consist of a stone toe along the bank below the water surface which will be buried, and then a layer of stone revetment leading up the slope at which point the revetment will become recessed and covered with a layer of topsoil that will continue up the remainder of the bank to the crest.

The construction will follow the existing topography of the land adjacent to the river. The topsoil will then be planted with native herbaceous and small shrub vegetation which will extend to the crest of the slope. The upper crest of the slope will then be re-planted with trees. The upper portion of the bank above the stone revetment will be covered with biodegradable erosion fabric and vegetated with wood shrubs and vines with the stone revetment placed along the lower section and along the toe of the bank.

Construction is scheduled to start on or about Sept. 1, 2014 and take about 4 months to complete.
