About this map

The Livermore Valley and the Valle de San Jose anchor this early twentieth-century study of the East Bay interior. The landscape is defined by the convergence of several major watercourses, including Arroyo de la Laguna and Arroyo del Valle, which join near the established settlements of Pleasanton and Livermore. The mapping highlights the infrastructure of the Southern Pacific and the Niles and Sacramento Line, illustrating how rail connectivity drove the growth of agricultural hubs and post offices like Dougherty P O.

Further south, the terrain rises into the Sunol Ridge and Pleasanton Ridge, leading toward the historic grounds of Mission San Jose and Ex Mission San Jose. This era shows a transition from sprawling Mexican land grants to more structured townships, evidenced by the inclusion of smaller rail stops like Verona, Brightside, and Sunol. The presence of features such as The Lagoon near Irvington provides a detailed view of the regional hydrology before modern development significantly altered these wetlands.
