Calabasas and the western San Fernando Valley margins are defined here by a transition from dense residential grids to the deeply etched drainage basins of the Simi Hills. The map traces the winding paths of Las Virgenes Cr and Bell Cr through numerous named canyons, illustrating how the area's development is dictated by the steep topography. Notable land use includes the Los Angeles Pet Cem near the southern hills and large-scale water management features like Chatsworth Reservoir and Runkle Reservoir. Small enclaves such as Chatsworth Lake Manor and Hidden Hills sit alongside commercial hubs at Brents Junction and Agoura. The landscape remains marked by large holdings like Gebel Ranch and Rancho Sombra Del Roble, reflecting the region's ranching heritage even as suburban expansion reaches into East Las Virgenes Canyon and up toward Calabasas Highlands.
