The 450,000-acre (180,000 ha) zone in which the conservancy can acquire land is bounded on the south by the Pacific Coast Highway from Santa Monica to Point Mugu. The zone extends inland roughly 50 miles (80 km) from Malibu north to Newhall Pass and 65 miles (105 km) from Thousand Oaks east to Pasadena. Several major freeways in Los Angeles cross the zone, including the Hollywood, Ventura, San Diego and Interstate 5.
