White House eyes underground security hub beneath Sherman Park

The White House is seeking to build a 33,000-square-foot underground security screening center beneath Sherman Park to streamline visitor checks, with seven lanes and a target to open by July 2028, as part of a broader grounds overhaul. The plan, developed with the Secret Service and National Park Service, will be reviewed by the National Capital Planning Commission in April, and a separate proposal for a 90,000-square-foot building with a ballroom at the former East Wing site is also under consideration, while the Sherman Park monument would remain intact.
