17th Street Closure

The 17th Street closure is a removable structure that can be erected in the event of high water to attach to the floodwalls on both sides of 17th Street and consists of aluminum panels between steel posts. The closure is part of the DC "Potomac Park" Levee System and the Washington, D.C. and Vicinity Local Flood Protection Project. It was designed and constructed by the U.S. Army Corps of Engineers, and is operated and maintained by the National Park Service to reduce Potomac River flooding to the Federal Triangle, areas west of the Capitol and Southwest D.C.
