1942 Map of Lompoc

About this map

Lompoc and the surrounding Santa Barbara County coastal hills are documented here during the early years of American involvement in World War II. The landscape shows a distinct division between the grid-patterned streets of the main town along Ocean Avenue and the industrial activity at the Diatomaceous Earth Quarries to the south. This era is marked by the presence of the CCC Camp near Mission La Purisima, reflecting New Deal-era infrastructure projects that remained active or recently transitioned as the region shifted toward wartime readiness. The Santa Ynez River meanders through the center of the sheet, flanked by the Southern Pacific railroad and a network of canyons including Cebada Canyon and Purisima Canyon. Rural education centers like Maple Sch, Santa Rita Sch, and Jalama School are scattered across the valley floors, serving the ranching communities that defined the interior beyond the river banks.
