About this map

Arroyo Grande and the central coast of San Luis Obispo County are captured here during a period of mid-century growth. The map illustrates the coastal development of Pismo Beach, Grover City, and Oceano, framed by the extensive Sand Dunes to the south. Along the Southern Pacific rail line, small sidings and settlements like Hadley, Callender, and Bromela mark the agricultural and industrial corridor.

Inland, the landscape transitions from the valley floors into the San Luis Obispo Range and Newsom Ridge. Notable landmarks include several rural education sites such as Oak Park Sch and the Branch School, as well as resort features like Sycamore Springs and Hidden Valley Hot Springs. The geography is defined by a complex network of canyons and creeks, including See Canyon and Tar Spring Creek, which support the region's diverse terrain and early 20th-century land use patterns.
