1968 Map of El Toro

About this map

El Toro Marine Corps Air Station dominates the central landscape of this survey, surrounded by the rapidly expanding residential and industrial footprints of El Toro and Serrano. The map documents a period of significant suburban transformation, where agricultural land-use at the South Coast Agriculture Field Station sits adjacent to the massive military installation and the County Industrial Farm. To the northeast, the terrain rises sharply into the Lomas de Santiago and Loma Ridge, leading toward the Cleveland National Forest. In these canyons, smaller settlements like Silverado and Modjeska retain a more secluded character. Water management is a visible priority across the arid terrain, evidenced by features like the Siphon Reservoir, Lambert Res, and the channelized reaches of Agua Chinon Wash and Borrego Canyon Wash.
