1950 Map of Camarillo

About this map

Camarillo State Hospital and the sprawling campus of St Johns Seminary anchor the southern landscape of this mid-century survey, where the Santa Monica Mountains descend into the fertile Pleasant Valley. The map documents a period of significant military and infrastructure development, featuring the Oxnard Air Force Base and the Pacific Missile Range Naval Res at its southern margin. Transportation networks are in transition as the Ventura Freeway and Southern Pacific railroad cut through the agricultural heartland, connecting the developing town of Camarillo with outlying settlements like Springville and Leesdale. The drainage patterns of Calleguas Creek and Revolon Slough define the low-lying plains, while the northern terrain rises into the Las Posas Hills. This 1950 data, updated in 1968, captures the shift from a ranching economy, represented by the Broome Ranch, toward the urban expansion and institutional presence that would define modern Ventura County.
