The National Park Service is moving ahead with plans to repair, rebuild and raise aging and crumbling seawalls in Washington, D.C., including landmark areas around the Tidal Basin—the site of the Jefferson Memorial and Japanese cherry trees, whose springtime blossoms annually draw throngs of visitors.
Under a $5.7-million task order from the park service, a team of HDR and Moffatt & Nichol is working on design and other early stage work for an initial segment of the project.
