City of Pleasanton—Merritt Property Project <br />15183 Consistency Checklist Consistency Checklist <br /> <br /> <br /> 131 <br />improvement costs. Therefore, impacts related to surface water and flooding <br />would be less than significant. <br />Polluted Runoff <br />The Housing Element Update FEIR indicated that new development <br />consistent with the Housing Element Update could increase the total <br />impervious area and increase stormwater runoff, which could exceed <br />stormwater drainage facility capacity or create additional sources of <br />polluted runoff. <br />The Housing Element Update FEIR concluded that compliance with the <br />General Plan policies and programs would maximize infiltration and rainwater <br />retention, which would in turn reduce stormwater runoff. Additionally, all <br />future development consistent with the Housing Element Update would be <br />evaluated on a project-by-project basis for impacts to storm drain capacity. <br />Further, new development would be required to pay its fair share of the storm <br />drainage system improvement costs. Therefore, impacts related to <br />exceedances in stormwater drainage systems or the creation of substantial <br />additional sources of polluted runoff would be less than significant. <br />Flood Flows <br />As depicted in the Housing Element Update Draft EIR in Exhibit 3.9-1, most of <br />the rezoned housing sites are not located within a flood hazard zone. <br />A small portion of the eastern portion of Site 22 (Merritt) is located within the <br />100-year flood hazard zone, and the eastern portion of Site 22 (Merritt) is <br />within the 500-year Federal Emergency Management Agency (FEMA) flood <br />hazard zone. <br />The Housing Element Update FEIR concluded that development consistent <br />with the Housing Element Update would be subject to the General Plan <br />policies and programs and Municipal Code, and compliance with those <br />regulation would reduce the risks of flooding. Furthermore, federal and State <br />agencies are also responsible for maintaining flood protection features in the <br />City. Additionally, all future development consistent with the Housing Element <br />Update would be evaluated on a project-by-project basis for impacts <br />related to flooding and would mitigate impacts as appropriate. Therefore, <br />the potential for loss, injury, or death from impeding flood flows would be less <br />than significant.
