City of Pleasanton—Stoneridge Mall Residential Project Section 15183 Checklist/15164 Addendum CEQA Checklist FirstCarbon Solutions 179 Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480017/Consistency Checklist/21480017 Stoneridge Mall Residential Project Checklist Addendum_Updated.docx Analysis of Proposed Project As previously discussed, the proposed number of units, and therefore, the increase in water demand, has been accounted for as part of planned development under the Prior EIR. The Prior EIR determined that Zone 7 would meet the Housing Element’s water demand (675.6 acre-feet per year), that the existing water supply would provide sufficient water supply capacity, and that Zone 7 would provide verification of adequate water supplies for subsequent projects. In addition, to obtaining water supply verification from Zone 7, the proposed project would include drought- tolerant landscaping that includes low-flow or underground drip irrigation systems, which would further reduce water demand. While the City and Zone 7’s groundwater resources are affected by new water quality regulations, the project’s proposed number of units are below the thresholds of California Water Code Section 10912 and California Government Code Section 66473.7 requirements and do not require a full WSA. As noted above, consistent with the Prior EIR, Zone 7 will provide verification of adequate water supplies for the proposed project. The applicant’s Hydraulic Analysis noted a 0.10 MG storage impact that is addressed by increasing reservoir capacity.111 Impacts would continue to be less than significant with inclusion of MM 4.L-2, consistent with the Prior EIR, and Implementation Measure 1 for applicant to pay its pro rata share of the cost to increase reservoir capacity by 0.1 MG for the proposed project. There are no proposed changes, new circumstances, or new information that would cause new or more severe impacts. Therefore, there are no utility effects that are peculiar to the proposed project or the parcels on which the proposed project would be located. Impacts would be less than significant, and the proposed project would not result in a new or more severe adverse impact that was not previously identified in the Prior EIR. c) Wastewater Treatment Capacity Prior EIR Conclusions The Prior EIR determined that implementation of the Housing Element would generate additional demand on the regional wastewater treatment facility. The City’s contribution to the daily wastewater received by the treatment facilities resulting from the implementation of the Housing Element would increase from the current City’s daily wastewater flow. As discussed above, the potential sites for development under the Housing Element would be served by the DSRSD’s Regional Wastewater Treatment Facility and would not exceed the existing and future average dry- weather wastewater flow capacities of wastewater or the total wastewater wet-weather discharge capacities allocated to the City by the DSRSD. The Prior EIR concluded that any request for service resulting from new development would be subject to a site-specific evaluation of the existing wastewater treatment system’s capacity to service the development. Additionally, the Prior EIR found that the City has planned its wastewater treatment contracts with the appropriate agencies to accommodate future needs of General Plan buildout including new housing developments like those of the Housing Element. Therefore, impacts from the Housing Element to wastewater treatment capacity would be less than significant. 111 AKEL Engineering Group, INC. 2022.
