Section 3 2025 Urban Water Management Plan Service Area Description City of Pleasanton Public Draft | May 2026 3-1 EKI Environment & Water, Inc. 3 SERVICE AREA DESCRIPTION This section describes the Pleasanton’s water system and service area, including climate, population, demographics, and land uses to help in understanding various elements of water supply and demand. 3.1 General Description Pleasanton’s inception can be traced back to the 1850’s as a stagecoach stop along the main route to the gold fields. The City was incorporated in 1894, and in the twentieth century it grew into a thriving agricultural center with the production of grain, hay, and hops. Located in southeastern Alameda County at the junction of Interstate 580 and Interstate 680, Pleasanton is approximately 22 square miles. The city is bordered by Interstate 580 and the City of Dublin to the north, Livermore to the east, and unincorporated Alameda County to the south. The city lies predominantly on flat land formed by alluvial deposits from prehistoric streams flowing through the Livermore, Amador, and San Ramon Valleys to the San Francisco Bay. Geologic activity in the area has resulted in varying deposits of sand and gravel in the northeastern portion of the city. While the area once supported the cultivation of crops and livestock, today, Pleasanton is predominately urbanized, except for several vineyards at the eastern edge of the city and livestock grazing on Pleasanton Ridge and in the Southeastern Hills. The majority of Pleasanton occupies the Valley floor, which ranges in elevation from approximately 320 to 400 feet. Pleasanton is enclosed by hills on the west and southeast. The Pleasanton and Main Ridges to the west rise sharply above Foothill Road to peaks of 1,500 feet. These two ridges remain seismically active and feature complex terrain, densely wooded vegetation, and landslide prone soils. A series of gentle to steeply sloping hills extend south from Pleasanton into a valley containing the San Antonio Reservoir. Pleasanton’s water service area includes the city itself, as well as customers in Remen Tract (unincorporated Alameda County), along Happy Valley Road and Kilkare Canyon Road (just north of the unincorporated Town of Sunol), and west of Foothill Road. Pleasanton’s service area lies within the Alameda Creek watershed, a drainage basin that covers about 675 square miles between Mount Hamilton and Mount Diablo (Figure 3-1).  CWC §10631 (a) Describe the service area of the supplier…
