H.R. 307 would authorize the appropriation of $20 million annually through 2028 for the American Battlefield Protection Program (ABPP), which is managed by the National Park Service. The ABPP provides grants to state and local governments to share the cost of acquiring eligible battlefield sites for preservation and protection. Under current law, $10 million is authorized to be appropriated each year through 2021. Thus, relative to current law, the bill would increase the authorized amount by $10 million in 2020 and 2021. (In 2019, the Congress appropriated $10 million for the ABPP.)
Assuming appropriation of the authorized amounts and based on historical spending patterns, CBO estimates that implementing H.R. 307 would cost $69 million over the 2020-2024 period and $91 million after 2024. The costs of the legislation fall within budget function 300 (natural resources and environment).
