The National Park Service is seeking input from the general public on the rehabilitation of seawalls at the Tidal Basin and West Potomac Park in Washington D.C. as they work to address significant flooding negatively impacting the Tidal Basin and surrounding areas.

The National Mall Tidal Basin is a complex, iconic public landscape with some of our most renowned national monuments and includes places of remembrance and reflection that tell the history of our nation. Unfortunately, the instability of the land underneath the Tidal Basin, daily flooding, and crumbling infrastructure threaten its sustainability and visitor enjoyment.

The public comment period is a part of an established process conducted in accordance with the National Environmental Policy Act of 1969 (NEPA). The public can submit comments on the National Park Service website through September 12.
