BACKGROUND: Every three years the California Building Standards Commission (BSC) updates the Uniform Codes governing construction practices in the State of California. Affected state agencies review these codes, amend them, and the BSC adopts them in the California Administrative Code, Title 24. After the State Code is published, every City and County throughout the state has an opportunity to adopt the Codes with more stringent local amendments based on:local geological, topographical and/or climatic conditions. At this time only the California Electrical Code has been approved by the BSC. Staff has reviewed with the Building Official and Assistant City Attorney the proposed revisions and they are in support of the requested local amendments. All of the proposed amendments have been adopted by the City in the past. There is one minor clerical modification in the ordinance; certain amendments that were designated to be placed in the Electrical Code are now designated to be placed into the 1997 Uniform AGENDA ITEM C� Z:\My Documents\2004 Building Code12004 Calif Electrical Code Adoption.CC Staff Report 2.doc\L W\07 -25 -05 Adoption of 2004 California Electrical Code — Public Hearing and Adoption of Ordinance No. 1537 City Council Staff Report August 8, 2005 Administrative Code. There is no change in the amendment language from that adopted by the City Council in 2002. Please refer to Attachment 1 to review the proposed ordinance. Several previously adopted local amendments are not proposed for re- adoption during this Code revision process, as these local amendments are no longer necessary due to the provisions of the 2004 California Electrical Code now addressing those local amendments or them no longer being necessary do other revisions in the various construction codes adopted by the City. An overview of those previously adopted local amendments are not proposed for re- adoption is provided in Attachment 2 for the information of the City Council. In order to adopt the latest California Codes, the City must follow the procedure set forth in Section 50022.3 of the Government Code. The first reading of the Ordinance was conducted on June 13 and this public hearing has been scheduled by the City Council in compliance with the provisions of Section 50022.3 of the Government Code. Notice of this hearing has followed the procedure prescribed by Section 6066 of the Government Code. The Ordinance may be adopted after the public hearing. If the City Council determines to adopt the proposed code amendments, they would become effective on August 25, 2005. FISCAL IMPACT: None, complies with provisions of law to ensure the Uniform Codes are updated pursuant to Health and Safety Code § 18941.5. No changes in construction fees currently in effect are proposed. RECOMMENDATION: Conduct public hearing, receive public testimony, and adopt Ordinance Number 1537 with any amendments determined appropriate. O D • D APP' 4 D: / / j� i f i _ A .

Chapter 3 of said Administrative Code is amended by deleting Table 3 -A through Table 3 -H in their entirety." Section 5. In adopting the Codes as set forth in this Ordinance the City Council finds, determines and declares, pursuant to Health and Safety Code Section 17958.5, that the changes or modifications to the Codes, other than those that are administrative in nature, are reasonably necessary due to the following local climatic, geographic or topographical conditions: ❑ Climatic conditions: ❑ The City of Seal Beach is located in a semi -arid Mediterranean type climate. It annually experiences extended periods of high temperatures with little or no precipitation. Hot dry foehn (Santa Ana) winds, which may reach speeds up to 70 miles per hour, are also common to the area. These climatic conditions cause extreme drying of vegetation and common building materials and predispose the area to large destructive fires (conflagration). ❑ The climate alternates between extended periods of drought and brief flooding conditions. ❑ These dry climatic conditions and winds contribute to the rapid spread of even small fires originating in high density housing or vegetation. These fires spread very quickly and create a need for increased levels of fire protection and safety of electrical system installations. ❑ Topographical conditions: ❑ Traffic and circulation congestion is an artificially created, obstructive topographical condition, which is common in the City of Seal Beach and throughout Orange County. ❑ These topographical conditions combine to create a situation, which places fire department response time to fire occurrences at risk, and makes it necessary to provide safer electrical system installations to protect occupants and property. ❑ Geological conditions: ❑ The City of Seal Beach is located in an area of high seismic activity, seismic zone 4. The Newport- Inglewood Fault, located within the boundaries of the city, poses the greatest hazard to life and property. It is . believed this fault is capable of generating a maximum credible 7.5 magnitude earthquake. Because of the cities degree of urbanization and 1 1 2004 Calif Electrical Code Adoption.CC Staff Report 2 Adoption of 2004 California Electrical Code — Public Hearing and Adoption of Ordinance No. 1537 City Council Staff Report August 8, 2005 location on a major fault, the risk of structural damage and loss of life due to ground shaking is considerable. ❑ Major earthquakes are always accompanied by disruption of traffic flow and fires. During a major earthquake fire department resources would be extremely taxed, and the ability to respond to fires would be complicated and in some cases impossible. Safer electrical system installations would provide a degree of protection from fires even if water mains are damaged or destroyed. A. Section 110.5 is amended to allow discretion by the building official on the use of aluminum wiring where adequate safety measures can be ensured; and Section 310 -14 is amended to require continuous inspection when aluminum conductors size No. 6 and smaller are utilized. Findings: 1. Improper installation creates a potential fire hazard and aluminum wire size and conductors No. 6 and smaller requires greater precision and care for proper installation and to ensure proper torquing of connections at their termination points. 2. Fires due to improper installation have been experienced in the City, which makes this provision necessary. The building official discretion of aluminum wire size No. 6 and smaller is reasonably necessary to safeguard life and property within the City. B. Section 210.11 is amended to require an individual food waste grinder branch circuit; Section 210.23(a) is amended to specify certain allowable installations for 15- and 20- ampere branch circuits; and Section 240 -24 is amended to prohibit panels and switchboards containing overcurrent devices from being located in any closet, cabinet, toilet room or room containing a lavatory; Findings: 1. Improper installation of these circuits creates a potential fire hazard and can result in fires. 2. Fires due to improper installation have been experienced in the City, which makes these provisions necessary. Due to the potential for fire from seismic, wind events, and close exposures of structures within the City, these amendments are reasonably necessary to safeguard life and property within the City. C. Section 300.6(B) is amended to specific installation procedures on the installation of electrical wiring in contact with or buried in the earth. 12 2004 Calif Electrical Code Adoption.CC Staff Report 2 Adoption of 2004 California Electrical Code — Public Hearing and Adoption of Ordinance No. 1537 City Council Staff Report August 8, 2005 Findings: 1. Certain natural constituents in local soils are corrosive to certain types of common electrical system installation methods. 2. Corrosion of electrical components due to improper installation has been experienced in the City, which makes this provision necessary. The specified installation methods are reasonably necessary to safeguard life and property within the City. Section 6. If any section, subsection, subdivision, paragraph, sentence, clause or phrase of this ordinance or any part thereof is for any reason held to be invalid, such invalidity shall not affect the validity of the remaining portions of this ordinance or any part hereof. The City Council of the City of Seal Beach hereby declares that it would have passed each section, subsection, subdivision, paragraph, sentence, clause or phrase hereof, irrespective of the fact that any one or more sections, subsections, subdivisions, paragraphs, sentences, clauses or phrases be declared invalid.
