certain said changes and modifications to the California Building Code, 2010 Edition, the <br />California Plumbing Code, 2010 Edition, the California Mechanical Code, 2010 Edition, the <br />California Electrical Code, 2010 Edition, the California Existing Building Code, 2010 <br />Edition, and the California Fire Code, 2010 Edition, are reasonably necessary due to <br />local conditions in the City of Santa Ana. <br />Section 3. Amendments to Section 602.1 of the 2010 Edition of the California <br />Mechanical Code as recommended by the Planning and Building Agency are hereby <br />found to be reasonably necessary because of corrosion related to the high seasonal <br />humidity in this coastal area which prevents moisture collecting in flexible ducting of <br />evaporative cooling systems from draining and evaporating, contributing to the <br />deterioration of the ductwork thereby endangering a person's health and the <br />environment. <br />Section 4. Amendments to Sections 110.5 and 334.12 of the 2010 Edition of the <br />California Electrical Code as recommended by the Planning and Building Agency are <br />hereby found to be reasonably necessary due to the following local conditions: <br />A. Earthquakes are a common occurrence in the local area; that earthquakes <br />may cause electrical connections and screws to loosen, causing arcing problems <br />especially in the smaller sizes of aluminum wire; and that the above amendment is <br />necessary to address the risk of fire due to such causes. <br />B. Earthquakes are a common occurrence in the local area; that, unlike wire <br />installed in conduit or raceways, non-metallic sheathed cable does not provide the <br />degree of protection that is needed in the event of an earthquake; that exposed non- <br />metallic sheathed cable is particularly hazardous; and that this amendment is necessary <br />to assure that adequate protection is provided in the workplace and in other places of <br />public gathering. <br />Section 5. Amendments to Sections 202, 507, 903, 907, 907.2.13, and 907.7.3.2 <br />of the 2010 Edition of the California Fire Code as recommended by the Fire Department <br />are hereby found to be reasonably necessary due to the following local conditions: <br />A. Climatic and geographic conditions of high winds and low humidity <br />combine to create an environment that is conducive to rapidly spreading fire. Control of <br />such fire requires rapid response. Obstacles generated by a strong wind, such as fallen <br />trees, street lights and utility poles, and the requirement to climb 75 feet vertically up <br />flights of stairs will greatly impact the response time to reach an incident scene. Also the <br />City is located in the middle of the seismically active area identified as Seismic Zone 4. <br />The viability of the public water system would be questionable after a large earthquake <br />leaving tall buildings vulnerable to uncontrolled fires and the inability to pump sufficient <br />quantities of water to upper floors. <br />B. Climatic conditions of high winds and low humidity combined with high <br />density city population conditions may be conducive to rapidly spreading fires.
