Connecticut River Project on the Table

The U.S. Army Corps of Engineers, New England District is proposing to perform a riverbank protection project to stabilize approximately 500 linear feet of riverbank along the Connecticut River in Lyme, New Hampshire.

According to the Corps, erosion is occurring at a section of river bank along the western side of River Road, just south of North Thetford Road in Lyme, where the bank is being undermined.

The proposed action consists of placing a stone revetment along a 500-linear-foot section of eroding Connecticut River bank located south of North Thetford Road, and running parallel to River Road. The stone revetment was considered to be the most practical solution to alleviate the erosion problems affecting the area.

To construct the revetment, approximately 5,100 cubic yards of interlocking, 18-inch riprap stone will be placed along the 500-linear foot segment of eroding bank.

The initial phase will involve the excavation of the eroding bank to create a constant slope, as well as to establish a stable foundation for the riprap slope. The bedding material will be composed of an initial 1-foot layer of sand followed by another 1-foot layer of gravel before the larger stone is placed.

The public notice, with more detailed information, is available for review on the Corps website.
