ClientNoma Parks Foundation
Size37,000 sf

Reclaiming private land for public use, one of Washington D.C.’s most dangerous intersections has been targeted for vast improvements. The project kicked off with the demolition of a Wendy’s restaurant on site and implemented new road alignments to ease traffic congestion. SWA worked with NoMa community groups and the Department of Transportation on the new vision for the intersection.

For Mamie “Peanut” Johnson Plaza, named in a public vote after the first female pitcher in the Negro Leagues, the team drew inspiration from the surrounding context to develop concepts that protect pedestrians and provide sheltered areas to sit, eat, and play. Softly sloping berms are used as multi-functional elements buffering traffic, collecting stormwater, and providing sculptural seat-walls. The new design adds 75 shade trees, pollinator plantings, play elements, and protected bike lanes, reestablishing the intersection as a multimodal gateway rather than a hazard zone. In the first five months of 2025, crash numbers were already down 40% from pre-construction conditions.

Today, NoMa is one of the city’s most densely populated and transit-connected communities, home to nearly 13,000 residents navigating its streets daily. The new plaza, delivered through a partnership between DDOT, NoMa BID, and the NoMa Parks Foundation, creates safer connections between Eckington and the core of NoMa—turning a deadly knot into a safer public commons.
