Action Requested: Background Information: Financial City Council approval of ordinance adopting the National Electrical Code, 2002 Edition with local amendments. The city currently operates under the 2000 editions of the International: Codes and under the 1999 edition of the National Electrical Code. These codes are published on a three year cycle. The North Central Texas Council of Governments Executive Board with the recommendation of the Regional Code Coordinating Committee has recommended adoption of these codes except the Property Maintenance Code be adopted with regional amendments.

Two additional meetings were held to receive input from the area building contractors. Legal Review: This ordinance has been reviewed by the city attorney and changes have been made as recommended. Alternatives: Adopt the ordinance as recommended or direct staff to restudy any specific issues that may be of concern. Supporting Documents: Detailed memorandum to Garland Wilson dated June 21, 2004 Ordinance No. 875, 2003 National Electrical Code Staff Recommendation: Approve Ordinance No. 875 on first reading with an effective date of September 30, 2004.

RB /gw City of Southlake, Texas MEMORANDUM June 21, 2004 TO: Garland Wilson, Chief of Administrative Services FROM: Paul Ward, Building Official, and; Chuck Bloomberg, Plans Examiner SUBJECT: 2003 International Codes The ICC, International Code Council, is a nonprofit organization founded in 1994 to develop a single set of comprehensive and coordinated national model construction codes for use throughout the country. We as the City of Southlake have been involved and supportive throughout the code development process and the creation of the International Codes. This support has been through the North Texas chapter of the International Code Council and through the regional review process be the Regional Codes Coordinating Committee of the NCTCOG (North Central Texas Council of Governments). The I Codes were developed with the support of many organizations that have interest in the construction industry although the final vote on all items is by code officials only. Work on the International Codes has been a model of democracy, without territorial disparities getting in the way. The American Institute of Architects and the National Association of Home Builders were both very active participants in the code development process. The National Association of Home Builders has applauded the recent action by the International Code Council (ICC) to add "affordability" to the Purpose Statement section of the International Residential Code (IRC), which applies to one- and two - family homes. The City of Southlake has had a track record of supporting the latest edition of the codes. The code has been published every three years for a long time. Since the 1980's Southlake has adopted the new code within one year of it becoming available. Another important reason to be up to date with the latest codes is the ISO insurance rating. Their system will subtract points if the city is not on the current codes. We always need to be able to show that we are current with the latest codes. The Building Codes are a set of universally accepted standards adopted as guidelines for construction of buildings and related building operations. The term "building codes" is a generic phase that actually encompasses several individual codes, each of which must be approved and adopted by the City Council before they can be applied or enforced. These codes are periodically updated, primarily due to new products entering the marketplace, and minor revisions may be made under the term "local amendments." The National Electrical Code (NEC) defines the requirements for everything related to electrical service. For example the size of wire required to operate certain outlets or fixtures, the type of wire allowed to be used, and what type of devices must be included to protect the user against electric shock. Southlake currently operates under the 1999 NEC. The proposed ordinance will bring us up to date by adopting the 2002 edition of the National Electrical Code (2002 NEC). This ordinance was created from the framework of the previous ordinance, inserting the NCTCOG recommended regional amendments. 2002 National Electrical Code ORDINANCE NO. 875 AN ORDINANCE ADOPTING NFPA 70, THE NATIONAL ELECTRICAL CODE 2002 EDITION; PROVIDING FOR THE ADOPTION OF LOCAL AMENDMENTS THERETO; PROVIDING FOR RECORDING OF SUCH CODE AS A PUBLIC _RECORD; PROVIDING THAT THIS ORDINANCE SHALL BE CUMULATIVE OF ALL ORDINANCES; PROVIDING A SEVERABILITY CLAUSE; PROVIDING A SAVINGS CLAUSE; PROVIDING FOR PUBLICATION IN PAMPHLET FORM; PROVIDING FOR PUBLICATION IN THE OFFICIAL NEWSPAPER; AND PROVIDING AN EFFECTIVE DATE.
