1942 Map of Riverside and Vicinity

USGS Topo · Published 1942

About this map

The citrus-growing heart of Riverside is documented here at the end of the 1930s, showing a landscape defined by expansive irrigation and transit networks. Irrigation features like Mockingbird Res and the Santa Ana River supported the region's agricultural economy, anchored by the Univ. of California Citrus Experiment Sta. The map highlights a concentration of institutional history, including the Sherman Institute and La Sierra College, alongside public infrastructure such as the County Farm and County Hospital. Residential growth is evident in the grid of Riverside and outlying communities like Arlington and Casa Blanca. Transportation is a central theme, with the Union Pacific and Pacific Electric lines threading through the valley between the Pedley Hills and the Box Springs Mountains, connecting local industry to the broader Southern California market via thoroughfares like Magnolia Ave.
