Rim of the Valley Corridor Preservation Act

HR 5881, the Rim of the Valley Corridor Preservation Act, expands the Santa Monica Mountains National Recreation Area by adding the "Rim of the Valley Unit" to its boundary, as shown on specific maps dated 2001 and 2023. This directly affects the lands within the new boundary, which contain nationally significant natural resources like diverse ecosystems and cultural sites spanning over 10,000 years of Native American history. The bill modifies the park's legal boundary to include these lands, requiring future minor adjustments to be published in the Federal Register after notifying congressional committees. Existing water and utility facilities within the added area may continue operating but must minimize environmental impact. The expansion aims to better serve urban communities, particularly those historically underrepresented in national parks.
