BACKGROUND <br />The new California Building Code (CBC) was adopted by the State on July 1, 2007, and <br />the City must adopt these codes by January 1, 2008, to continue to be able to issue <br />building permits. The approval of the urgency ordinance provides for the adoption by <br />January 1 by eliminating the need for two readings of the ordinance and the 30 day <br />waiting period before the ordinance becomes effective. The proposed ordinance <br />amends the Pleasanton Municipal Code to coincide with the adoption of the 2007 <br />California Building Technical Codes, more commonly known as the Building, Plumbing, <br />Mechanical, Electrical and Fire Codes. These collective codes are also known as the <br />California Building Code (CBC). <br />The major change to the Codes is the decision by the California Building Standards <br />Commission to replace the Uniform Building Code (used since 1927) and the Uniform <br />Fire Code, with the International Building Code (2006 IBC) and the International Fire <br />Code (2006 IFC), as the base model codes for the new 2007 California Building Code <br />and the new 2007 California Fire Code, respectively. These model codes generally <br />represent the minimum standards of the three model codes that were previously used <br />throughout the United States. <br />DISCUSSION <br />The new code standards, in some cases, generally fall below our current standards of <br />construction and life-safety. Staff is proposing code amendments to restore some of the <br />life-safety features back to our existing code standards. In summary, these proposed <br />code amendments do not exceed the existing code standards currently being used by <br />the City. <br />The new Building and Fire Codes rely on automatic fire systems to provide property and <br />life safety protection for buildings and building occupants. To construct any building <br />with an automatic fire sprinkler system in the building is, without doubt, a great asset in <br />almost any fire event. However, allowing automatic fire sprinklers to be used to reduce <br />other passive safety measures such as fire walls, fire rated corridors, and width of <br />required exits, does not account for our local earthquake and wildfire concerns. <br />Passive building protections provide redundancy in the safety aspects of the <br />construction to allow our citizens to exit a building safely. More specifically, passive <br />provisions that are eliminated or reduced by the CBC include reduction in the <br />requirements for fire rated walls along a property line which would cause unprotected <br />openings right next to protected openings, reduction of the distance that exits must be <br />separated in a building, increasing a dead end corridor from 20 lineal feet to 50 lineal <br />feet (which is an issue in smoke filled rooms), and the removal of fire blocking and draft <br />stopping in ceilings, attics and concealed spaces. <br />The passive safety measures are important because the City of Pleasanton is subject to <br />natural disasters, including earthquake events from nearby faults, which could eliminate <br />availability of water for the automatic sprinkler systems. Pleasanton's water distribution <br />system, including water tanks, pumps, and underground piping, is all vulnerable to <br />Page 2 of 3 <br />
