Environmental Analysis March 2020 Page 99 Environmental Issues Substantial Change in Project Requiring Major EIR Revisions Substantial Change in Circum-stances Requiring Major EIR Revisions New Information Showing New or Increased Significant Effects Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR No Impact d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? x The Project Site (and the City of Santa Ana) is not within or near a Very High Fire Hazard Severity Zone according to CalFire. The Project Site is also not within or near in a State Responsibility Area (SRA). Comments: a) Substantially impair an adopted emergency response plan or emergency evacuation plan? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR. The Initial Study for the Approved Project states that there are no designated emergency evacuation rou tes in the City. As with the Approved Project, operation of the Proposed Project could interfere with response times of emergency vehicles but after implementation of appropriate mitigation would assure that impacts would remain less than significant. Incorporation of Mitigation Measures PS-1 through PS-9 would ensure that the Proposed Project would result in a less than significant impact to police protection, and fire and emergency services. Specifically, Mitigation Measures PS-8 would ensure that emergency vehicles receive green lights with preemption detectors at identified intersections. Therefore, the Proposed Project would not substantially impact an adopted emergency response plan or emergency evacuation plan. Therefore, the Proposed Project would not create a new significant impact or a substantial increase in the severity of previously identified effects that would require the preparation of a subsequent EIR. b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? No Impact. The Proposed Project is located in an urban environment and is surrounded by existing development. There are no wildland areas, nor wildland interface areas located in the vicinity. Consequently, no wildland fires would affect, or be affected by implementation of the Proposed Project. No impact would occur for the Proposed Project and no changes or new information would require preparation of a subsequent EIR. 5 - 153
