Architecture Month Event: Flood Resiliency for the National Mall

Please join us on June 3rd to learn about the existential threat of flooding on the National Mall, view designs for a comprehensive solution, and contribute your ideas.

In this hour-long webinar, the National Mall Coalition will present a unique approach to resiliency on the National Mall, one of the country’s most important public spaces affected by flooding. This event is part of Architecture Month 2020: Civic Spirit, a citywide celebration of the buildings and spaces that shape the capital, hosted by the Washington Chapter of the American Institute of Architects.

The resiliency concept is a multi-purpose underground facility called the National Mall Underground that acts as a stormwater reservoir, tour bus parking facility, and geothermal energy project.

Federal and District flood experts have been seeking a comprehensive solution to Mall area flooding since the flood of June 2006. That disaster, following three days of heavy rain, inundated Mall museums and public buildings along Constitution Avenue.

Stormwater flooding in June 2006 inundated Constitution Avenue (left); tour buses would be removed from the lower level of the National Mall Underground to allow floodwater to flow into that space.

The parking garage and geothermal components of the Underground provide solutions to other urgent needs, including clean energy for nearby public buildings and parking for tour buses that are now major sources of traffic congestion and air pollution.

During the webinar, exhibits presented will include photographs of historic Mall floods, maps illustrating the geography of flooding on the Mall, and recent reports raising new alarms about the scale of the flood threat to the public buildings and open spaces of the Mall. Speakers will include Arthur Cotton Moore, architect of the Underground, and Judy Scott Feldman, chair of the Coalition.

The Architecture Month theme “Civic Spirit” is perfectly apt for the Underground, since any solution to the stormwater flooding threat requires collaboration among a number of entities. The list responsible for Mall oversight includes congressional committees, federal agencies, DC government, plan review bodies, and others.

This event is part of Architecture Month 2020: Civic Spirit, a citywide celebration of the buildings and spaces that shape the capital. It is co-produced by the Washington Architectural Foundation and the Washington Chapter of the American Institute of Architects. Learn more and register at aiadc.com/ArchitectureMonth2020.
