The Amador Valley serves as the focal point for this survey of the East Bay interior, capturing a period of significant transition as agricultural lands began to give way to mid-century suburban expansion. The city of Livermore dominates the eastern half of the map, revealing a dense grid of residential growth around its core, while Pleasanton and East Pleasanton show early development patterns along the Southern Pacific and Western Pacific rail lines. This geography is defined by a network of waterways including Arroyo Mocho and Arroyo Valle, which intersect a landscape of heavy industry marked by numerous Gravel Pits.
