Rim of the Valley Corridor Preservation Act

This bill formally adds the "Rim of the Valley Unit" to the Santa Monica Mountains National Recreation Area by adjusting its boundaries. It specifies the exact land, water, and interests to be included, using two referenced maps (one from 2001 and a proposed 2023 addition). The addition does not change how the area is managed overall but requires that existing water and utility facilities continue operating while minimizing impacts on the area's natural resources. The change directly affects the lands within the newly defined boundaries, incorporating them into the existing national recreation area framework.
