Potomac Park Levee Project Environmental Assessment
The National Park Service (NPS), in cooperation with the District of Columbia (District), the U.S. Army Corps of Engineers (USACE) and the National Capital Planning Commission (NCPC), announces the availability of the Potomac Park Levee Project Environmental Assessment (EA) for public review and comment.
The EA evaluates a range of alternatives for the design and construction of improvements to the Potomac Park levee system located in Washington, D.C. The purpose of this action is to improve the reliability of river flood protection provided by the Potomac Park levee in a manner that respects the resources and values of the National Mall. Without adequate flood protection measures, several downtown District locations, including portions of the monumental core, portions of Pennsylvania and Constitution Avenues and the Federal Triangle, and other public and private facilities located south of the U.S. Capitol to Fort McNair, are at risk of flooding from a major (100-year plus) flood event.
