This bill significantly modifies the American Battlefield Protection Program, aiming to enhance the preservation and interpretation of historic battlefields across the United States. A key provision adjusts cost-sharing requirements , increasing the federal share for both the Battlefield Interpretation Modernization Grant Program and the Battlefield Restoration Grant Program from 50% to 75%, providing greater financial support for these critical preservation efforts. The legislation also extends the authorization for the Battlefield Acquisition Grant Program through fiscal year 2035 and authorizes an appropriation of $2,000,000 annually through the same year for the Interpretation Modernization and Restoration grant programs. This ensures continued funding for the acquisition of significant battlefield lands and enhanced support for interpretation and restoration. Furthermore, the bill mandates the Secretary of the Interior to conduct comprehensive studies of French and Indian War and Mexican-American War sites . These studies will identify, assess, and propose alternatives for the preservation and interpretation of these sites, requiring consultation with various stakeholders and a report to Congress within two years of funding.
