A truly innovative, comprehensive, public-private approach to Mall planning, the National Mall Underground consolidates in one multi-purpose facility the needs of all constituencies – local residents, Mall visitors, Smithsonian, National Park Service, District of Columbia government, Architect of the Capitol, General Services Administration, and others. The Underground will solve longstanding stormwater flooding problems and create a more welcoming, lively, and resilient Mall in the heart of the nation’s capital.
