Rim of the Valley Corridor Preservation Act

Introduced: May 22, 2025
Sponsor: Sen. Schiff, Adam B. [D-CA] (D-California)
Environment & Climate
Standard Summary
Comprehensive overview in 1-2 paragraphs

Rim of the Valley Corridor Preservation Act would expand the Santa Monica Mountains National Recreation Area (SMMNRA) by adding the Rim of the Valley Corridor to its boundary. The expansion is defined using two specific maps: the 2001 boundary map for the existing NRA and a 2023 map showing the Rim of the Valley Unit proposed addition. The bill provides a process for public access to these maps and allows the Secretary of the Interior to make minor boundary revisions with notice to key committees. Any land or interests acquired within the new Rim of the Valley Unit would be managed as part of the NRA under the same laws and regulations that apply to the NRA. The act also ensures that the addition does not disrupt water and utility facilities in the Rim of the Valley Unit, though activities must minimize impact on local resources.

Key Points

  • 1Boundary expansion: Adds the Rim of the Valley Corridor to the Santa Monica Mountains National Recreation Area, using two named maps as the official boundary references.
  • 2Maps and public access: The relevant boundary maps will be on file and publicly accessible in National Park Service offices.
  • 3Boundary revisions: After notifying Senate and House committees in writing, the Secretary may make minor boundary revisions via Federal Register publication.
  • 4Administration: Land or interests acquired within the Rim of the Valley Unit will be administered under the same NRA laws and regulations as other lands in the NRA.
  • 5Utilities and water facilities: The expansion should not affect the operation or maintenance of water/resource facilities within the Rim of the Valley Unit, but any activities must reasonably avoid or reduce impacts on the unit’s resources.
