S. 1870 — Rim of the Valley Corridor Preservation Act

This section expands the boundary of the Santa Monica Mountains National Recreation Area to include the Rim of the Valley Unit Proposed Addition, as generally depicted on the map entitled “Proposed Addition - Rim of the Valley Unit Santa Monica Mountains National Recreation Area,” numbered 638/179670x and dated April 14, 2023 (in addition to lands depicted on the existing boundary map numbered 80,047–C and dated August 2001). It requires the maps to be on file and available for public inspection in appropriate National Park Service offices and authorizes the Secretary to make minor boundary revisions after written notice to the Senate Committee on Energy and Natural Resources and the House Committee on Natural Resources (previously the House Committee on Resources), via publication in the Federal Register.

This section directs the Secretary of the Interior to administer any land or interest in land acquired within the Rim of the Valley Unit as part of the Santa Monica Mountains National Recreation Area in accordance with applicable laws and regulations for that area.

This section provides that adding the Rim of the Valley Unit to the National Recreation Area does not affect the operation, maintenance, or modification of water resource facilities or public utilities within the unit, except that such activities must be conducted in a manner that reasonably avoids or reduces impacts on unit resources.
