About this map

The coastal hills and agricultural valleys of San Luis Obispo County come into focus during this mid-1960s survey, updated with late-1970s suburban growth. The landscape is defined by the Southern Pacific railroad corridor, which links the small community of Edna to the growing coastal hubs of Pismo Beach and Grover City. Educational and social markers like Independence Sch and the San Luis Obispo Country Club illustrate the transition from rural ranching to modern residential expansion.

Along the rugged eastern edge, the Los Padres National Forest rises toward peaks like Bald Mtn and Slide Hill. The map meticulously details the complex drainage system of the Corral De Piedra and Arroyo Grande Creek, alongside numerous oil wells and a high-elevation Airway Beacon on Islay Hill. This period of development is particularly evident in the corporate boundaries of Arroyo Grande, showing where the town meets the historic ranch lands of the Bolsa De Chamisal.
