More than four decades after a graduate student proposed adding a "green belt" of wildlife habitats, parks, and recreational areas in a rim circling the San Fernando Valley, Rep. Adam Schiff is pushing to add as much land as possible "Rim of the Valley Corridor" to the Santa Monica Mountains National Recreation Area in the Los Angeles area. Backed by a broad coalition including the National Park Service, the designation would protect of the 1,000-square-mile area from future development and preserve puma and bobcat habitats, along with forests and fossil beds. "For us, it's a complete and utter enhancement," Las Virgenes Homeowners Federation president Kim Lamorie told the LA Times. "Our [residents] are always competing to get the National Park Service - to purchase land in and around our homeowners associations and rural villages.... Property values go up when you're surrounded by open space."
