C-46 | City of Pleasanton Housing Constraints Measure (MM) HAZ-2, which requires the preparation of a Phase I Environmental Site Assessment (Phase I ESA) and Phase II ESA (as necessary) for review and approval by the City and completion of any necessary remedial activities to be conducted under the oversight of the appropriate regulatory agency, such as the Alameda County Environmental Health Department or Regional Water Quality Control Board. The EIR states that compliance with applicable federal, State, and local laws, as well as local plans and regulations, in addition to implementation of MM HAZ-2 would provide public protection from hazards associated with the use, transport, treatment, and disposal of hazardous substances during construction and operation of development consistent with this Housing Element. With incorporation of this mitigation measure, which reduces any potentially significant effects from contamination to a less than significant level at these rezone sites, possible contamination does not represent an environmental constraint that would preclude development of housing sites identified in Appendix B. In addition, according to the California Environmental Protection Agency and California Office of Environmental Health Hazard Assessment’s CalEnviroScreen 4.0 Indicator Maps (CalEnviroScreen), there are no known hazardous waste sites at any of the sites in the sites inventory in Appendix B. As described in the paragraph above, Rezone Site 22 (Merritt Property) is a cleanup site as described by CalEnviroScreen, but MM HAZ-2 would address any impacts of contamination as may be found at this site. There are no other known environmental constraints that would preclude development on sites identified in the housing sites inventory, including easements, property conditions, lack of compatibility with other land use controls, necessary site mitigations, or timing impacts. Where constraints related to land use controls exist (as previously identified in this Appendix), programs are included to address and remove the constraint. C.4.2 Infrastructure Constraints Water Supply Water supply is an issue at the forefront of long-term planning efforts in the City.Water supply is an issue at the forefront of long-term planning efforts in the City. A Water Supply Assessment (WSA) was completed for the proposed land use changes, re-zonings and residential growth associated with the 6th Cycle Housing Element, as part of the required CEQA evaluation. The WSA, which was developed in consultation with the City’s main water supplier, Zone 7, looked at long- and short-range water supply issues based on an evaluation of demand and available supply, with findings based primarily on the City’s 2020 Urban Water Management Plan (UWMP). The WSA concluded that for Normal year water supply, single dry year water supply, and multi- dry year water supply Zone 7 is able to provide enough water supply to account for the City’s water demand projections from 2020 through 2045. The projected total demand falls within the water demand projections reported in the UWMP for the years 2023 through 2025, but slightly exceeds projections reported in the UWMP for the years 2030 through 2045 (exceedances of approximately 3.5 percent (2031) and 1.5 percent (2045). However, the WSA utilized extremely
