This chapter describes the City's water system facilities and service area. In addition, this chapter discusses the climate, population, demographics, and land use within the City's service area. 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. The City is approximately 22 square miles and is located in southeastern Alameda County at thejunction of Interstate 580 and Interstate 680. Water service is currently provided to all City residents and commercial customers, as well as portions of unincorporated Alameda County (i.e., Remen Tract, Happy Valley, and the area west of Foothill/Sunol). 3.2 SERVICE AREA BOUNDARY The City's water service area includes the City, as well as customers in unincorporated Alameda County in Remen Tract, along Happy Valley Road and Kilkare Canyon Road (just north of the Town of Sunol), and west of Foothill Road. Pleasanton's service area lies within the Alameda Creek watershed, a drainage basin covering about 675 square miles between Mount Hamilton and Mount Diablo. Figure 3-1 shows the City's limits and its current water service area. 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, and once supported the cultivation of crops and livestock. Modernly, Pleasanton has predominately been urbanized, with the exception of 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. WEST YOST 3-1 City of Pleasanton 2020 Urban Water Management Plan May 2021
