ORDINANCE NO. 2011- AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF NEWPORT BEACH AMENDING TITLE 9 OF THE NEWPORT BEACH MUNICIPAL CODE TO ADOPT LOCAL AMENDMENTS TO THE FIRE CODE The City Council of the City of Newport Beach finds as follows: WHEREAS, the Fire Marshal of the State of California has adopted that certain fire code, entitled "2010 California Fire Code" based upon the 2009 International Fire Code published by the International Fire Code Institute, which, with certain deletions, amendments, exceptions, and additions, and including certain appendices, which apply only to those occupancies regulated by the California State Fire Marshal, has been copyrighted and published by the California Building Standards Commission; and WHEREAS, the Newport Beach Fire Chief finds it necessary to adopt local amendments to apply regulations reasonably necessary to protect the health, welfare and safety of the residents and visitors of Newport Beach in those occupancies not regulated by the California State Fire Marshal; and WHEREAS, the Newport Beach Fire Chief finds it necessary to amend the previously adopted 2010 California Fire Code and 2009 International Fire Code in order to maintain consistency between several sections of the 2010 California Fire Code, 2009 International Fire Code and the 2010 California Building Code; and WHEREAS, Health and Safety Code Sections 13143.5, 17958, and 18941.5 permit the City to amend, add, or repeal ordinances or regulations which impose the same requirements as are contained in the ordinances and regulations adopted by the State of California, if the City Council- makes the express findings pursuant to Sections 17958.5 and 17958.7 of the Health and Safety Code; and WHEREAS, Health & Safety Code Section 17958.7 requires that the City Council, before making any changes or modifications pursuant to Section 17958.5, make express findings that such changes or modifications are needed due to climatic, geographic, or topographic conditions; and Amendment of NBMC Title 9, Fire Code January 25, 2011 Page 5 WHEREAS, the Fire Chief has recommended that changes and modifications be made to the Fire Code that are reasonably necessary due to the following local climatic, geographical, or topographical conditions: A. The City of Newport Beach is located in an area subject to a climatic condition of high winds. This environment is conducive to rapidly spreading fires, and control of such fires requires rapid response. Obstacles generated by a strong wind, such as fallen trees, streetlights and utility poles, may greatly impact the response time to reach an incident scene. B. The City of Newport Beach is located in the middle of the seismically active area identified as Seismic Zone 4. The viability of the public water system would be questionable, at best, after a major seismic event. This would leave tall buildings vulnerable to uncontrolled fires due to a lack of available water and an inability to pump sufficient quantities of available water to floors in a fire. A severe seismic event has the potential to negatively impact any rescue or fire suppression activity because it is likely to create obstacles similar to those indicated under the high wind section above. With the probability of strong aftershocks there exists a need to provide increased protection for anyone on upper floors of buildings. C. Due to the topographical conditions of sprawling development separated by waterways, narrow and congested streets, and the expected infrastructure damage inherent in the seismic zone described above, it is prudent to rely on automatic fire sprinkler systems to mitigate extended fire department response time and keep fires manageable with reduced fire flow (water) requirements for a given structure. D. The City of Newport Beach has several areas with significant growth of wildland vegetation of a highly combustible nature that could threaten structures and the surrounding community. That threat, combined with the potential for high winds described above, warrant additional construction requirements for specific areas that have increased danger should a fire occur. Amendment of NBMC Title 9, Fire Code January 25, 2011 Page 6 NOW, THEREFORE, the City Council of the City of Newport Beach ordains as follows: SECTION 1.
