1959 Map of Briones Valley

About this map

La Boca de la Cañada del Pinole defines the central canyon landscape of this East Bay survey, where rural valleys and early suburban expansion meet. The map documents the residential growth of Lafayette and Orinda Village at the southern edge, contrasting with the open ridgelines of Briones Hills and Sobrante Ridge. Strategic water infrastructure is a dominant theme, including the sprawling San Pablo Reservoir, the Mokelumne Aqueduct, and Lafayette Reservoir. Transportation and education networks are well-established, from the Atchison Topeka and Santa Fe railroad in the north to local landmarks like Briones Valley School and Sleepy Hollow School. The map captures the complex terrain of the Briones Valley before later decades of densification, preserving the names of small settlements like Glen Frazer and Christie along the rail line.
