Section 4 2025 Urban Water Management Plan <br />Water Use Characterization City of Pleasanton <br /> Public Draft | May 2026 <br /> 4-7 EKI Environment & Water, Inc. <br />4.5 Projected Water Demand <br />Future water demands within Pleasanton’s service area are estimated as the sum of demands associated <br />with existing users and those associated with planned/proposed new development. <br />4.5.1 Basis of Demand Projections <br />The City’s demand projections account for planned/proposed development projects within Pleasanton’s <br />service area. As part of the 2024 WDSCMP, the City evaluated future demands related to new <br />development in its service area (see also Section 3.4). The demand projections reflect new development <br />for the following land uses: <br />• Residential – The City’s RHNA allocation for the 6th Cycle (2023-2031 Housing Element) was 5,965 <br />units. To meet this requirement, the City’s 2023-2031 Housing Element identified <br />planned/proposed single family and multi-family residential developments in four categories: (1) <br />Approved Entitled Sites, (2) ADUs, (3) Housing Sites, and (4) Rezone Sites. The City estimated the <br />number of new dwelling units within each category based on general site density information <br />listed for each site, then calculated estimated water demand considering the number of people <br />per dwelling unit and per capita water use. Larger multi-family residential developments are <br />anticipated to include DIMs for landscape water use. Therefore, a portion of the water demand <br />associated with these developments is accounted for as new irrigation demand, rather than <br />residential demand. <br />• Industrial – A proposed new development in the east Pleasanton area involves a light industrial <br />component. (The project also involves residential development that is identified in the Approved <br />Entitled Sites portion of the 2023-2031 Housing Element and reflected in the future residential <br />water use projections.) The additional water demand associated with the proposed industrial <br />project (102 AFY by 2045) is treated as an incremental increase to those identified in the 2023- <br />2031 Housing Element . <br />The WDSCMP projected that commercial water demands will remain relatively constant through 2045.The <br />City estimates that planned development will increase the total water demand within its service area by <br />3,170 AFY between 2025 and 2045. <br />4.5.2 Water Savings from Codes, Standards, Ordinances, or Transportation and Land Use <br />Plans <br /> <br />Water savings from passive conservation may reduce water use intensity among existing and future <br />customers. Passive conservation refers to water savings resulting from actions and activities from codes, <br /> CWC §10631(d)(4) <br />(A) Water use projections, where available, shall display and account for the water savings estimated to result <br />from adopted codes, standards, ordinances, or transportation and land use plans identified by the urban water <br />supplier, as applicable to the service area. <br />(B) To the extent that an urban water supplier reports the information described in subparagraph (A), an urban <br />water supplier shall do both of the following: <br />(i) Provide citations of the various codes, standards, ordinances, or transportation and land use plans utilized in <br />making the projections. <br />(ii) Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or <br />transportation and land use plans. Water use projections that do not account for these water savings shall be <br />noted of that fact.
