1906 Map of Pleasanton

About this map

Mission San Jose and the historic Ex Mission San Jose lands anchor the southwestern portion of this early twentieth-century landscape, where the Santa Clara Valley meets the East Bay ridges. The development of the Amador Valley and Livermore Valley is clearly visible through a network of small agricultural settlements and post offices such as Dublin, Dougherty P O, and Sunol. Transportation corridors define the region's economy, with the Southern Pacific and Western Pacific railroads threading through the Niles Canyon area near Merienda and Brightside. The map captures the complex drainage systems of the Arroyo de la Laguna and Alameda Creek, alongside notable landmarks like Mission Pass and the The Lagoon, providing a detailed look at the transition from Spanish colonial heritage to the burgeoning rail-driven towns of Livermore and Pleasanton.
