17, 1989, Santa Cruz earthquake resulted in one major fire in the Marina <br />District (San Francisco). When combined with the 34 other fires locally <br />and over 500 responses, the department was taxed to its fullest <br />capabilities. The Marina fire was difficult to contain because mains <br />supplying water to the district burst during the earthquake. This situation <br />creates the need for both additional fire protection and automatic on -site <br />fire protection for building occupants. State Department of Conservation <br />noted in their 1988 report (Planning Scenario on a Major Earthquake on <br />the Newport -Inglewood Fault Zone, page 59), "unfortunately, barely <br />meeting the minimum earthquake standards of building codes places a <br />building on the verge of being legally unsafe." <br />B. Road circulation features located throughout the County also make <br />amendments reasonably necessary. Located through the County are major <br />roadways, highways and flood control channels that create barriers and slow <br />response times. Hills, slopes, street and storm drain design accompanies <br />with occasional heavy rainfall, causes roadway flooding and landslides and at <br />times may make an emergency access route impassable. There are areas in <br />Orange County that naturally have extended emergency response times that <br />exceed the 5 minute goal. <br />C. Soils throughout the County possess corrosive properties that reduce the <br />expected usable life of water services when metallic pipes in contact with <br />soils are utilized. <br />Due to the topographical conditions of sprawling development separated by <br />waterways and narrow and congested streets and the expected infrastructure <br />damage inherent in seismic zone described above, it is prudent to rely on <br />automatic fire sprinkler systems to mitigate extended fire department response <br />time and keep fires manageable with reduced fire flow (water) requirements for a <br />given structures. Additional fire protection is also justified to match the current <br />resources of firefighting equipment and personnel within the Orange County Fire <br />Authority. <br />Section 4. The following specific amendments to the sections of the 2019 Edition <br />of the California Building Code as recommended by the Planning and Building Agency <br />and the Orange County Fire Authority are reasonably necessary based upon the <br />corresponding findings in Section 3 of this resolution as listed below: <br />BUILDING <br />CODE SECTION <br />TITLE (Clarification) <br />FINDINGS I,II,III <br />105.1 <br />Permits required <br />Admin <br />105.3.2 <br />Time Limitation of Application <br />Admin <br />105.5 <br />Permit Expiration <br />Admin <br />111 <br />Certificate of Occupancy <br />Admin <br />Resolution No. 2019-116 <br />Page 4 of 8 <br />
