SB 3524 updates the American Battlefield Protection Program by extending the grant program through 2035 and changing cost-sharing rules for two grant tracks. It also creates a dedicated annual appropriation for ABPP grants and directs the Interior Department to study and report on war-era sites tied to the French and Indian War and the Mexican-American War.
The bill does not enact new taxes or create new agencies; it shifts funding and requirements within existing authorities to strengthen preservation and interpretation.
At a Glance
What It Does
Extends ABPP grant authorization to 2035; increases non-federal cost-sharing for modernization and restoration grants to 75%; repeals an existing subsection related to flexibility; and authorizes $2 million per year through 2035 for ABPP grants.
Who It Affects
The National Park Service and Interior Department program administrators, state historic preservation offices, Tribal governments, local governments, preservation nonprofits, and grant applicants seeking ABPP funds.
Why It Matters
Longer funding certainty supports preservation work and site interpretation; higher cost-sharing targets may improve local buy-in but could affect project viability for smaller communities; the bill also elevates focus on major historic sites through targeted studies.

What This Bill Actually Does
The bill makes three broad moves. First, it extends the life of the ABPP grant programs through fiscal year 2035, ensuring continuity for communities that rely on these funds.
It also makes changes to how certain ABPP grants are funded by adjusting the required share of the cost that non-federal entities must cover, increasing it for the modernization grants from 50% to 75%, and removing a nesting provision that previously allowed another pathway for costs. In addition, it establishes an explicit annual appropriation of $2 million to fund these grants through 2035, signaling a more predictable funding stream for program administrators and applicants.
Second, the bill directs a new line of work focused on battlefield studies. It requires the Secretary of the Interior (through the National Park Service) to prepare studies of sites tied to the French and Indian War (1754–1763) and the Mexican-American War (1846–1848).
These studies must identify relevant sites, assess their significance and threats, and lay out preservation and interpretation options, including potential designation as units of the National Park System where appropriate. The intent is to better map and protect historically significant locations and to inform federal, state, local, and Tribal preservation efforts.
Finally, the bill requires coordination with relevant stakeholders in developing these studies—governors, tribes, local governments, preservation organizations, and other interested parties—and calls for a report to Congress within two years after funds are made available for the studies. Taken together, the measure seeks to stabilize funding for battlefield preservation while expanding federal attention to a defined set of historic sites.
The Five Things You Need to Know
The bill extends ABPP grant program authorization to 2035.
Non-federal cost-sharing for the modernization grant track rises from 50% to 75%.
A dedicated $2,000,000 annual appropriation for ABPP grants is authorized through 2035.
The Secretary must study French and Indian War and Mexican-American War sites, identifying locations and preservation options.
A report on study results must be submitted to Congress within two years of funds being available.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short Title
Section 1 designates the act as the American Battlefield Protection Program Amendments Act of 2025. This section anchors the act’s identity and sets the stage for the amendments that follow, without altering substantive grant authorities beyond the changes codified in Section 2.
American Battlefield Protection Program Grant Programs
Section 2 contains the grant-related amendments. Subsection (a) reauthorizes the Battlefield Acquisition Grant Program by moving the reauthorization from 2028 to 2035, providing longer-term continuity for acquisitions funded under the ABPP. Subsection (b) adjusts the Battlefield Interpretation Modernization Grant Program: the required non-federal cost share in subsection (c) is increased from 50% to 75%, and subsection (d) is repealed, removing an existing procedural pathway. Subsection (c) applies a similar adjustment to the Battlefield Restoration Grant Program, increasing the non-federal cost share from 50% to 75% and substituting the previous subsection (e) with a new authorization: funds to support grants under sections 308104 and this section are set at $2,000,000 per year through fiscal year 2035. These changes shift how grant projects are funded and broaden the federal commitment through a higher annual appropriation cap.
French and Indian War and Mexican-American War Sites Studies
Section 3 requires the Secretary of the Interior (via the National Park Service) to prepare studies of U.S. sites thematically tied to the French and Indian War (1754–1763) and the Mexican-American War (1846–1848). The studies must identify sites, assess their significance, evaluate threats to their integrity, and propose preservation and interpretation options. The recommendations may include designating certain sites as units of the National Park System, as appropriate, and should consider information from earlier studies by the National Park Service, the American Battlefield Trust, or other preservation organizations. The effort is designed to guide future preservation priorities and federal involvement in key war-era landscapes.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- State Historic Preservation Offices (SHPOs) and Tribal Historic Preservation Offices (THPOs) gain clearer program guidance and more stable funding pathways for preservation projects.
- Local governments and public land managers can plan and implement battlefield-related preservation and interpretation projects with enhanced cost-sharing and a predictable funding outlook.
- Nonprofit preservation organizations (e.g., the American Battlefield Trust) gain a formal mechanism and funding stream to advance site identification, protection, and education efforts.
- Museums, universities, and other research institutions benefit from a defined program alongside an expanded study agenda, facilitating partnerships and grant-supported research.
Who Bears the Cost
- Federal taxpayers fund the annual ABPP grants for 2035 under the new authorization.
- States, Tribes, and local governments incur higher requirements for non-federal cost-sharing on modernization and restoration projects.
- Grant applicants must secure a larger portion of funding from non-federal sources to meet the 75% threshold, potentially shifting project viability toward well-resourced entities.
Key Issues
The Core Tension
The central dilemma is balancing broader federal commitment with greater local cost-sharing: more state and community buy-in through higher matches vs the risk of reducing project access for smaller communities. The bill seeks to preserve and interpret important war-era sites while imposing higher financial thresholds and a new study mandate that requires coordination across multiple levels of government and civil society.
The bill’s increased non-federal cost-sharing could constrain smaller communities or projects lacking matching funds, potentially narrowing the pool of eligible projects despite longer authorization and funding. The higher match burden may shift competition toward larger or better-supported proposals, while the added wartime-site studies raise expectations for proactive preservation planning and intergovernmental coordination.
On the implementation side, the $2 million annual appropriation must be sustained alongside other Interior Department priorities, and the two-year reporting deadline creates a tight timeline for coordinating with governors, Tribes, and preservation groups to deliver meaningful results.
