ONE BROADWAY PLAZA PROJECT EIR ADDENDUM <br />CITY OF SANTA ANA <br />5. Environmental Analysis <br />Less Than <br />Significant <br />Substantial <br />Impact/No <br />Substantial <br />Change in <br />New <br />Changes or <br />Change in <br />Circum- <br />Information <br />New <br />Project <br />stances <br />Showing New <br />Information <br />Requiring <br />Requiring <br />or Increased <br />Requiring <br />Major EIR <br />Major EIR <br />Significant <br />Preparation of <br />Environmental Issues <br />Revisions <br />Revisions <br />Effects <br />an EIR <br />No Impact <br />d) Expose people or structures to significant <br />risks, including downslope or downstream <br />flooding or landslides, as a result of runoff, <br />X <br />post -fire slope instability, or drainage <br />changes? <br />The Project Site (and the City of Santa Ana) is not within or near a Very High Fire Hazard Severity Zone <br />according to CalFire. The Project Site is also not within or near in a State Responsibility Area (SRA). <br />Comments: <br />a) Substantially impair an adopted emergency response plan or emergency evacuation plan? <br />Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR. <br />The Initial Study for the Approved Project states that there are no designated emergency evacuation routes in <br />the City. As with the Approved Project, operation of the Proposed Project could interfere with response times <br />of emergency vehicles but after implementation of appropriate mitigation would assure that impacts would <br />remain less than significant. Incorporation of Mitigation Measures PS-1 through PS-9 would ensure that the <br />Proposed Project would result in a less than significant impact to police protection, and fire and emergency <br />services. Specifically, Mitigation Measures PS-8 would ensure that emergency vehicles receive green lights with <br />preemption detectors at identified intersections. Therefore, the Proposed Project would not substantially impact <br />an adopted emergency response plan or emergency evacuation plan. Therefore, the Proposed Project would <br />not create a new significant impact or a substantial increase in the severity of previously identified effects that <br />would require the preparation of a subsequent EIR. <br />b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose <br />project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a <br />wildfire? <br />No Impact. The Proposed Project is located in an urban environment and is surrounded by existing <br />development. There are no wildland areas, nor wildland interface areas located in the vicinity. Consequently, no <br />wildland fires would affect, or be affected by implementation of the Proposed Project. No impact would occur <br />for the Proposed Project and no changes or new information would require preparation of a subsequent EIR. <br />Apri12020 Page 99 <br />
