Passed Senate

Big Bend National Park Boundary Adjustment Act

119th Congress Introduced Mar 25, 2025

Summary

What This Bill Does

The Big Bend National Park Boundary Adjustment Act authorizes the Secretary of the Interior to acquire about 6,100 acres shown on a November 2022 National Park Service map and add the land to Big Bend National Park. Acquisition may happen only by donation or exchange.

The bill bars condemnation and eminent domain. Once land or interests in land are acquired, the Secretary must revise the park boundary and administer the added acreage as part of Big Bend National Park under existing park laws and regulations.

Who Benefits and How

Big Bend National Park, the National Park Service, park visitors, conservation organizations, local tourism businesses, and nearby communities benefit from voluntary expansion and protection of additional land connected to the park. Private landowners benefit from explicit protection against condemnation or eminent domain.

Who Bears the Burden and How

The Secretary of the Interior and National Park Service must manage map records, negotiate donation or exchange transactions, revise the park boundary, and administer acquired acreage. Federal land managers must take on stewardship, maintenance, and regulatory responsibility for any land added to the park.
