HR-1289-114
Placed on Senate Legislative Calendar under General Orders. Calendar No. 584.
Sponsored by Mark DeSaulnier (D-CA)
What it does
This bill would allow the Department of the Interior to accept donated land — up to approximately 44 acres — and add it to the John Muir National Historic Site in Martinez, California. The acquired land would be managed as part of the existing historic site. No purchase of land is authorized; acquisition is limited to donations only.
Who benefits
Visitors and tourists to the John Muir National Historic Site, who would have access to a larger preserved area. Residents of Martinez, California and the surrounding Contra Costa County area, who may see increased tourism and economic activity. Historians, educators, and researchers focused on John Muir's life and the conservation movement. The National Park Service, which would gain additional land under its stewardship. Landowners who wish to donate the acreage and may receive tax benefits for doing so.
Who is hurt
Current private owners or users of the 44 acres, if they are not the ones initiating the donation, could face social or community pressure to donate. Local property tax rolls in Martinez could be reduced if the donated land was previously taxable, potentially affecting the city and county's tax revenue. Neighboring property owners could face increased visitor traffic, noise, or congestion if the expanded site draws more tourists.
Supporters argue
Supporters argue that expanding the John Muir National Historic Site preserves land directly connected to one of America's most influential conservationists at no cost to taxpayers, since only donated land may be acquired. They contend that protecting additional acreage surrounding the site maintains the historical integrity and natural character of the landscape Muir himself inhabited, providing a more complete and authentic experience for visitors and students. Supporters also note that the bill imposes no federal spending mandate — the Interior Department may accept donations but is not required to — making it a low-risk, fiscally responsible way to enhance a nationally significant cultural and historical resource.
Opponents argue
Opponents argue that adding 44 acres to a federal historic site permanently removes that land from local tax rolls and private use, shifting long-term maintenance costs onto the National Park Service at a time when the agency already faces a significant deferred maintenance backlog. They contend that land management decisions of this kind are best handled at the state or local level, and that federal expansion of historic sites — even through donation — incrementally grows the federal government's land holdings in ways that may not reflect the priorities of local communities. Opponents may also question whether the additional acreage meaningfully enhances the site's historical or educational value enough to justify the ongoing federal administrative burden.
Constitutional context
The bill rests on Congress's authority under the Property Clause (Article IV, Section 3, Clause 2), which grants Congress broad power to manage federal lands and property. The Necessary and Proper Clause (Article I, Section 8) supports the administrative framework for the National Park Service to manage the expanded site. Because acquisition is limited to voluntary donations, Takings Clause concerns (Fifth Amendment) are not implicated. The bill does not raise significant Commerce Clause, Tenth Amendment, or major questions doctrine issues, as it is a narrow, site-specific land management measure rather than a broad regulatory action. Recent cases such as WV v. EPA (2022) and Loper Bright (2024) are not directly relevant given the bill's limited and clearly authorized scope.
Checks and balances
The bill grants the Executive Branch (Department of the Interior) discretionary authority to accept donated land and administer it as part of the historic site. Congress retains oversight through appropriations for site management. No new regulatory authority is created, and no judicial role is implicated. The balance of power between branches is minimally affected.
Historical precedent
Congress has routinely passed legislation authorizing the expansion of National Park Service units through land donation or purchase, including numerous boundary adjustment acts for existing historic sites throughout the 20th and 21st centuries.
