Statement of Findings for Local Government Amendments 2010 Califomia Fire Code The amendments to the Califomia Fire Code sections listed below are necessary because Campbell is located in a region subject to significant seismic activity. A large seismic event may initiate numerous fires and calls for emergency assistance within the City. The amendments to the listed sections provide additional safeguards for Fire Department personnel and increase the effectiveness of suppression operations and emergency responses since available fire fighting resources will be diminished during aCity-wide disaster. 316.6 503.1 503.1.1 503.2.1 504.4 510.1.1 1411.1 The amendments to the Califomia Fire Code sections listed below are necessary because Campbell is located in a region subject to significant seismic activity. A large seismic event will likely initiate numerous structure fires within the City. The amendments to the listed sections will, over time, increase the number of sprinkler-protected properties and improve the level of sprinkler protection in those structures. Fire sprinkler protected buildings will be less susceptible to destruction by earthquake-caused fires as responses by fire suppression crews may be significantly delayed during a major City-wide seismic event. 903.2 903.3.1.1 903.3.1.2 903.3.1.3 The amendments to the sections listed below are necessary because Campbell is located in a region subject to significant seismic activity. Should a significant seismic event occur, hazardous materials releases could pose significant threats to both the commercial and the adjacent residential areas. Should a major seismic event occur, local emergency response resources would be seriously impacted and maybe unavailable to effectively respond to all incidents. These amendments wilt reduce the hazardous materials release potential through enhanced containment, detection andlor suppression facilities, equipment and systems. 1802 2701.2.2.2 2703.1.3.1 2703.1.5 2703.1.6 2703.2.2.1 2703.2.2.2 2703.5.2 2703.5.3 2703.9.8 2703.9.11 2704.2.1 2704.2.2 2705.4.4 3103 3404.2.7.5.8 3404.2.7.5.9 3701.3 3702 3704.1.4 3704.1.5 3704.1.6 3704.1.7 3704.1.9 3704.1.10 3704.1.11 3704.1.12 3704.1.16 3704.1.17 3704.2 3704.2 Table 3704.2.1 3704.2.1.1 3704.2.2 3704.2.2.7 3704.2.2.10.1 3704.3 3704.3 Table 3704.3.1 3704.3.1.1 3704.3.3 4105.3.1
