Salem Maritime National Historical Park Redesignation and Boundary Study Act

HR 1647 redesignates the "Salem Maritime National Historic Site" as the "Salem Maritime National Historical Park" (effective immediately upon enactment), updating all federal references to the park's name. It requires the Secretary of the Interior to conduct a 3-year boundary study evaluating whether to expand the park to include maritime, coastal defense, and military history sites in Salem, Massachusetts, and its vicinity. The study will assess the suitability and feasibility of adding these areas to the National Park System, with a report due to Congress within three years of funding. This bill makes no immediate changes to park boundaries but initiates a formal review process for potential future expansion.
