Adjusts the boundary of the Santa Monica Mountains National Recreation Area to include the Rim of the Valley Corridor.

The Rim of the Valley Corridor Preservation Act amends the National Parks and Recreation Act of 1978 to adjust the boundary of the Santa Monica Mountains National Recreation Area to include the Rim of the Valley Corridor. The Secretary of the Interior may make minor revisions to the recreation area's boundaries after notifying relevant committees. The addition of the Rim of the Valley Unit will not affect the operation, maintenance, or modification of water resource facilities or public utilities within the unit, except that activities must reasonably avoid or reduce impacts on resources.
