This expressed finding is <br />supported and based upon the following more specific findings and determinations: <br /> <br />Located within, or immediately contiguous to, the northerly and easterly corporate limits <br />of the City of Santa Ana are foothills commonly referred to as the Puente Hills and the <br />Chino Hills (hereinafter collectively referred to "the foothill areas"). <br /> <br />Significant growths of vegetation of a highly combustible nature. The City of Santa <br />Ana, including the foothill areas, is geographically located in an area periodically <br />subject to wind conditions of high velocity. Moreover, the topographical conditions of <br />the foothill areas, and canyons contained therein, tend to accelerate the periodic high <br />velocity winds by means of a venturi effect. <br /> <br />The City of Santa Ana, including the foothill areas, is located with an area subject to high <br />temperatures coupled with Iow humidity on a seasonal basis. <br /> <br />The use of non-rated or special purpose roofing materials as roof coverings within the <br />City of Santa Aha may create an inordinate fire hazard during periods of high velocity <br />winds when fire may spread across building with roof coverings of non-rated combustible <br />materials. <br /> <br />Embers from chimneys without spark arresters within the City of Santa Ana, including the <br />foothill areas, coupled with the climatic, topographical and geographical conditions <br />described herein above may permit the throwing of sparks, embers and cinders upon <br />non-rated and special roofing materials roofs during periods of high velocity winds thereby <br />creating a fire hazard which in turn may spread throughout areas where the roofs of <br />structures are covered with untreated wood shakes and shingle. <br /> <br /> SECTION 15: That section 8-116 is added to Chapter 8 of the Santa Ana <br />Municipal Code to read in full as follows: <br /> <br />Table 15-A is amended to read as follows: <br /> <br />TABLE NO. 15-A MINIMUM ROOF CLASSIFICATION (3) <br /> <br /> TYPES OF CONSTRUCTION .... <br /> <br />OCCUPANCY I II III IV V <br /> <br /> FR ER 1,HR .N 1-HR ; N HT 1-HR. <br /> N <br /> <br />A-1 B B ....... <br /> <br />Ordinance No. NS-2522 <br />Page 10 of 47 <br /> <br /> <br />
