U.S. Army Corps of Engineers Takes South Mountain Dam and Retention Basin Proposal Off the Table


WEST ORANGE, NJ - The United States Army Corps of Engineers has taken the South Mountain Reservation Dam-Detention Basin for Rahway Flood Abatement off the table after a series of public meetings, comments, and a Department of Environmental Protection review of the plan.

On July 17, John Moyle of the New Jersey Bureau of Dam Safety and Flood Control, recommended that the U.S. Army Corps of Engineers consider "more economically feasible and less environmentally destructive" flood options be pursued for the Rahway River Flood Risk Management Feasibility Study as the original plan for an 80-foot dam and 80-acre detention basin at the heart of South Mountain reservation would no longer be considered.

Moyle recommended that "Alternative 4," (Channel improvement with modifications to Orange Reservoir outlet pipes) and "Alternative 7A," (10 year non-structural meaures) be undertaken.
