ITEM 23 ATTACHMENT 1 - CEQA Checklist

City of Pleasanton—Merritt Property Project Consistency Checklist 15183 Consistency Checklist 132 Inundation The Housing Element Update FEIR indicated there are no large, confined water bodies within the City susceptible to seiches and that no portion of the City is located on a shoreline susceptible to tsunamis. Therefore, development consistent with the Housing Element Update would not result in substantial inundation by seiche or tsunami, and no impact would occur related to a release of pollutants due to related inundation. The Housing Element Update FEIR indicated that several rezoned housing sites are within the 500-year flood hazard zone, and small portions of Site 22 (Merritt) are located within the 100-year flood hazard zone (see Housing Element Update Draft EIR Exhibit 3.9 1). Development consistent with the Housing Element Update would be subject to the General Plan policies and programs and the Municipal Code, which would reduce the risks of inundation. Additionally, all future development would be evaluated on a project-by-project basis for impacts related to risk of pollutant release associated with flooding and inundation. Therefore, the risk of release of pollutants during inundation would be less than significant. Water Quality Control or Sustainable Groundwater Management Plans Consistency The Housing Element Update FEIR indicated construction and operation of any future development consistent with the Housing Element Update could result in water quality impacts. In addition, future development consistent with the Housing Element Update could lead to an increased demand for water, which could lead to an increase in groundwater pumping. The Housing Element Update FEIR concluded that any future development consistent with the Housing Element Update would be required to comply with the General Plan policies and programs, the Municipal Code, and the mandatory NPDES permit requirements. Therefore, during construction and operation, future development consistent with the Housing Element Update would not violate any water quality standards or otherwise substantially degrade surface or groundwater quality, in compliance with the Water Quality Control Plan for the San Francisco Bay Basin. Furthermore, compliance the General Plan contains policies and programs that would facilitate groundwater recharge by encouraging pervious surfaces in new developments and requiring projects to meet federal, State, regional, and local stormwater requirements, including stormwater infiltration. Therefore, implementation of the Housing Element Update would not conflict with or
