2025 Urban Water Management Plan

Section 3 2025 Urban Water Management Plan Service Area Description City of Pleasanton Public Draft | May 2026 3-6 EKI Environment & Water, Inc. • Section 4 Water Use Characterization – specifically, Section 4.7 discusses potential climate change impacts on water demands; • Section 6 Water Supply Characterization – specifically, Section 6.10.1 discusses potential climate change impacts on supplies; and • Section 7 Water Supply Reliability Assessment. 3.3 Population and Demographics As a midsize suburban city, the City is known as a desirable place to live and work, with a high-quality school system, parks and recreational facilities, a traditional downtown area, and a low crime rate. Land use planning within the City’s service area is guided by the 2005-2025 General Plan and 2023-2031 Housing Element. Single-family residential development remains the largest water customer sector in Pleasanton (46% of all potable demands in 2025). 3.3.1 Population The estimated historical and current population served by the City is based on California Department of Finance (DOF) population estimates and Decennial Census data (Figure 3-5). Pleasanton’s service area population in 2025 was 77,232, a noteworthy decrease compared to the population in 2020. This decrease can be attributed to demographic fluctuations from the COVID-19 pandemic. Before 2020, the City experienced steady population growth, averaging approximately 1.1% annually over the previous two decades. The City anticipates population growth to resume between 2025 and 2030 at a reduced rate of roughly 0.6% per year. Beyond 2030, population growth is projected to rebound to pre-pandemic rates, averaging approximately 1.2% annually. By 2045, the total population within Pleasanton’s service area is expected to be 94,407. Future population projections are consistent with other local planning documents, including DSRSD’s Regional Wastewater Treatment Plant (WWTP) Master Plan. DSRSD’s WWTP Master Plan Update relies on Plan Bay Area 2040 4 projected population growth rates through 2040 (ABAG, 2017). Population projections are derived from the City’s 2024 WDSCMP, which reflects the growth projected in the City’s 2023-2031 Housing Element (Pleasanton, 2024). Pleasanton’s current and projected service area population are shown in Table 3-2 and Figure 3-5 in five- year increments through 2045. 4 DSRSD’s WWTP Master Plan update is currently in process of development and uses Plan Bay Area 2040 Projections by Jurisdiction, as summarized in the City of Dublin’s 2023-2031 Housing Element. Plan Bay Area 2050 projections are not used because they are based on subcounty areas (super-districts), which are a combination of cities, towns, and unincorporated areas.  CWC §10631 (a) Describe the service area of the supplier, including current and projected population … other social, economic and demographic factors affecting the supplier’s water management planning. The projected population estimates shall be based upon data from the state, regional, or local service agency population projections within the service area of the urban water supplier and shall be in five-year increments to 20 years or as far as data is available.
