1929 Map of Chatsworth

About this map

Oakwood Cemetery and the distinct rock formations of Garden of the Gods anchor this topographical study of the rugged borderlands between Ventura and Los Angeles Counties. Surveyed in 1929, the map reveals a transition from the developing Twin Lakes Addition to the undeveloped stretches of Simi. The landscape is defined by its deep drainages, including Dayton Canyon and Bell Canyon, which reveal the complex terrain that governed early 20th-century expansion. The steel of the Southern Pacific railroad line cuts across the northern landscape, illustrating the vital infrastructure connecting this foothill region to the larger southern California network. While the southern portions of the map show the expanding City of Los Angeles boundary, the presence of isolated water sources like H-a-Leah Sprs and Devil Creek highlights the essential role of natural hydrology in shaping the settlement patterns of this arid environment.
