1974 Map of San Clemente

About this map

San Clemente sits on the edge of the Pacific Ocean in this mid-1970s orthophotoquad, which uses aerial photography to capture the coastal expansion and military landscape of Orange County. Large portions of the terrain are dominated by the Camp Pendleton Marine Corps Base, showing the juxtaposition between the dense residential street grids of the coastal town and the undeveloped training grounds to the south and east. The photography reveals the drainage patterns and rugged topography of the backcountry, particularly where Gabino Canyon and Talega Canyon carve through the hillsides. This visual survey provides an unfiltered look at the 1974 coastline, documenting the transition from suburban development to protected military and natural lands before the major growth of subsequent decades.
