City of Pleasanton 2023-2031 (6th Cycle) Housing Element Update Final EIR Errata FirstCarbon Solutions 3-31 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480022/EIR/4 - Final EIR/21480022 Sec03-00 Errata.docx As shown in Table 3.15-8, with all the City’s groundwater supply wells being taken out of commission, and unless the supply is either replaced or restored, there would be a significant projected water supply deficiency for all years reported in this analysis. The deficiency ranges from approximately 12 percent to approximately 25 percent. Without the groundwater supply, there would not be enough water available to account for development consistent with the Housing Element Update unless alternative water supplies are identified, such as purchasing additional water from Zone 7 Water Agency. Although Zone 7 has sufficient supplies available, b Because the City is still evaluating options for additional water and has not finalized additional supplies at the time of publication of this Draft Program EIR, the potential water supply deficiency is considered significant for the purpose of this analysis. Page 3.15-37, Second Full Paragraph In response to ZONE 7-6, the following paragraph has been revised: With the suspension of the Groundwater Wells Rehabilitation Project, more alternative water supply options are being considered by the City to replace the deficiency associated with the loss of groundwater supply. The additional options being considered include the following: • Drilling of new City wells with or without PFAS treatment, depending on the location of the wells. This option would require test drilling and groundwater sampling; • Discussion between Zone 7 and the City have taken place with the option of Zone 7 providing 100 percent of all water supply, both in the near term and explore the option of Zone 7 providing 100 percent of all water supply in the long-term in the future; and • Consideration of purchasing water supply from outside Zone 7. Section 3.16—Wildfire Page 3.16-21, Second Paragraph To provide clarification, the following paragraph has been revised: Further, most development under consistent with the Housing Element Update is expected to occur in urbanized and developed areas where existing infrastructure (including utilities, highways, and roadways) are already in place. The Housing Element Update would retain the existing roadway patterns. As the City receives development applications for subsequent development consistent the Housing Element Update, those applications would be reviewed by the City for compliance with the fire protection measures identified in the General Plan, the California Fire Code, and the California Public Resources Code General Plan and California Fire Code to ensure that fire risks are not exacerbated. As such, the Housing Element Update does not propose the installation and maintenance of any new infrastructure that would substantially exacerbate fire risk, and impacts would be less than significant.
