1947 Map of Briones Valley

USGS Topo · Published 1954

About this map

The San Pablo Reservoir dominates the western portion of this 1940s landscape, serving as a critical water node with its Intake Tower and nearby Filtration Plant. This era shows the East Bay transitioning from ranching lands toward more concentrated residential pockets in Orinda Village and Lafayette. The rugged interior is defined by massive land grants and ridge systems like La Boca de la Cañada del Pinole and the Briones Hills, where traditional rural life is still evidenced by the Briones Valley Sch.
