1952 Map of Calabasas

About this map

Simi Hills and the northern reaches of the Santa Monica Mountains dominate this 1952 topographic study, showing the region during a significant period of suburban transition. The map records the early footprints of communities like Woodland Hills and Hidden Hills, while the western canyons remain largely open and rural. Of particular note is the Motion Picture Country House and Hospital near the junction of the Ventura Freeway and Mulholland Drive, serving as a landmark of the local film industry's history. The landscape is deeply carved by drainage systems such as Las Virgenes Canyon and Cheeseboro Canyon, contrasting with the engineered basin of the Chatsworth Reservoir to the northeast. Purple map updates from 1967 reveal the rapid expansion of the Los Angeles city boundary into the formerly unincorporated hills, as traditional ranching and open land gave way to mid-century residential development.
