Baltimore District civil engineers and levee safety teams joined @NationalMallNPS in Wednesday's annual exercise of the 17th Street closure, a post-and-panel structure in the Potomac Park Levee System along the #NationalMall in Washington, D.C.

ALT National Park Service teams in bright green construction jackets install large metal panels across a roadway using a crane. The video is sped up to timelapse speed.

The closure can be fully closed to provide additional riverine flood protection to downtown D.C. 🌧️ It's operated & maintained by the National Park Service and was designed & built by the Baltimore District, who inspects it upon completion of the exercise.

SM-1 began operations in 1957. In addition to supporting Fort Belvoir, the facility helped establish pioneering operating data that informed nuclear power development, and its completed decommissioning helps the Army understand the full lifecycle of nuclear power.

Earlier this year, James Island was all but lost to the erosive forces of the Chesapeake Bay. But as part of our Mid-Bay project, the island's footprint is starting to re-appear on the map off the coast of Maryland's Dorchester County.

This long-term, 30+ year project continues our strategy for providing viable placement alternatives that meet the dredging needs of the @portofbalt while maximizing the use of dredged materials as a beneficial resource.

Restoration of island habitat is necessary and valuable to the Chesapeake Bay ecosystem: in the last 150 years, ~10,500 acres of this type of habitat have been lost in the mid-eastern portion of the Bay, a valuable region for resting & nesting sites for migratory and shore birds.

This cyclical work creates more than just a beautiful beach: the combination of a wide beach, a protective seawall, and a vegetated dune system has served as an engineering shield to prevent an estimated $927 million in storm damages since the early 1990s.

This project succeeds because of the deep relationships built between our federal team, the @MarylandDNR, @WorcesterCounty, the Town of Ocean City, the Marine Mining Administration, and our leaders in Congress. Expect more updates soon on this upcoming renourishment.

Prefabricated wall panels were one of the biggest efficiency gains on site, which not only sped up construction but also simplified quality control by narrowing inspection to a defined set of points rather than open-ended fieldwork.
