Rim of the Valley Corridor Preservation Act

Bill Summary: Rim of the Valley Corridor Preservation Act (H.R. 3874)

Overview

The Rim of the Valley Corridor Preservation Act is a legislative proposal designed to expand the boundaries of the Santa Monica Mountains National Recreation Area (SMMNRA). The primary intent of the bill is to formally incorporate the "Rim of the Valley Unit" into the existing national recreation area, ensuring the preservation of this specific corridor of land and water.

Key Provisions

1. Boundary Expansion

The bill amends the National Parks and Recreation Act of 1978 to officially redraw the boundaries of the SMMNRA. The recreation area will now include:
* All lands and waters originally depicted in the August 2001 boundary map.
* The additional lands and waters identified in the "Proposed Addition—Rim of the Valley Unit," as depicted in the map dated April 14, 2023.

2. Administrative Control

All new lands or interests in land acquired within the Rim of the Valley Unit will be managed by the Secretary of the Interior. These areas will be administered under the same laws and regulations that currently govern the rest of the Santa Monica Mountains National Recreation Area.

3. Protections for Utilities and Infrastructure

To prevent operational disruptions, the bill includes a specific carve-out for public utilities and water resource facilities. The addition of the Rim of the Valley Unit will not interfere with the operation, maintenance, or modification of these facilities. However, the bill mandates that such activities must be conducted in a manner that "reasonably avoids or reduces the impact" on the natural resources of the unit.

4. Flexibility for Refinements

The Secretary of the Interior is granted the authority to make "minor revisions" to the boundaries. To do so, the Secretary must notify the House and Senate Committees on Natural Resources in writing and publish the changes in the Federal Register.

Who is Affected?

• The National Park Service (NPS): Will take on the responsibility of administering the newly added acreage.
• Public Utility and Water Resource Providers: While their operations are protected, they must adhere to resource-impact mitigation standards when working within the unit.
• The Public: Residents and visitors of the Santa Monica Mountains region will benefit from the expanded preservation and federal protection of the Rim of the Valley corridor.

Procedural Status

• Introduced: June 10, 2025
• Current Status: Referred to the House Committee on Natural Resources.
