Thousand Oaks and Westlake Village dominate the interior of this 2015 survey, where the suburban landscape meets the northern boundary of the Santa Monica Mountains National Recreation Area. The map reveals a complex interface of developed residential neighborhoods and preserved natural terrain, particularly around the Simi Hills and Simi Peak. Established landmarks such as the Olson Cemetery and Valley Oaks Memorial Park Cemetery provide points of interest for local researchers, while the area's hydrology is marked by Westlake Lake, Lake Sherwood, and the Wood Ranch Reservoir. The transition between Ventura and Los Angeles counties is clearly delineated as it passes through Agoura Hills and Malibu Junction, illustrating the continuous growth across this Southern California corridor.
