aerial type fire fighting apparatus above this height would place rescue personnel at <br />increased risk of injury. <br /> <br /> The City of Santa Ana is located in the middle of the seismically active area <br />identified as Seismic Zone 4. The viability of the public water system would be <br />questionable at best after a major seismic event. This would leave tall buildings <br />vulnerable to uncontrolled rites due to a lack of available water and an inability to pump <br />sufficient quantities of any available water to floors above the 55-foot level. A severe <br />seismic event has the potential to negatively impact any rescue or fire suppression <br />activities because it is likely to create obstacles similar to those indicated under the high <br />wind section above. With the probability of strong aftershocks there exists a need to <br />provide increased protection for anyone on upper floors. <br /> <br /> SECTION 11: That section 8-114 is added to Chapter 8 of the Santa Ana <br />Municipal Code to read in full as follows: <br /> <br />Sec 8-114.
