Each ordinance also contains Palo Alto’s proposed local amendments to each part of the CBSC, along with the necessary findings of fact supporting each local amendment. CMR:385:07 Page 1 of 5 BACKGROUND The five ordinances are described below: 1. Ordinance repealing Chapter 16.04 of the Palo Alto Municipal Code and amending Title 16 to adopt a new Chapter 16.04, California Building Code, California Historical Building Code, and California Existing Building Code, 2007 Editions, and Local Amendments and Related Findings - The California Building Code (CBC) is the fundamental building code within the State of California that regulates most new building construction and is based on the 2006 International Building Code (IBC), written by the International Code Council (ICC), as amended by the California Building Standards Commission. The California Historical Building Code (CHBC) is unique to California and prescribes building standards for designated historic structures aimed at balancing the goals of historic preservation with life, safety and accessibility concerns when the provisions of the regular building code cannot be achieved. The 2007 California Existing Building Code (CEBC) is based on the 2006 International Existing Building Code, also written by the ICC, as amended by the Building Standards Commission. Similar to the CHBC, the CEBC prescribes alternative building standards for existing structures when the provisions of the regular code cannot be achieved. Ordinance adopting a new Chapter 16.05 of the Palo Alto Municipal Code, California Mechanical Code, 2007 Edition - The California Mechanical Code (CMC) is based on the 2006 Uniform Mechanical Code (UMC), written by the International Association of Plumbing & Mechanical Officials (IAPMO), as amended by the Building Standards Commission, and prescribes standards for mechanical heating, ventilating and cooling systems, and appurtenant equipment, within buildings. Ordinance repealing Chapter 16.08 of the Palo Alto Municipal Code and amending Title 16 to adopt a new Chapter 16.08, California Plumbing Code, 2007 Edition, and Local Amendments and Related Findings - The 2007 California Plumbing Code (CPC) is based on the 2006 Uniform Plumbing Code (UPC), also written by the IAPMO, as amended by the Building Standards Commission, and prescribes standards for water and wastewater distribution systems, and appurtenant equipment, within buildings. Ordinance repealing Chapter 16.16 of the Palo Alto Municipal Code and amending Title 16 to adopt a new Chapter 16.16, California Electrical Code, 2007 Edition, and Local Amendments and Related Findings - The 2007 California Electrical Code (CEC) is based on the 2005 National Electrical Code, written by the National Fire Protection Agency (NFPA), as amended by the Building Standards Commission, and prescribes standards for electrical supply and operating systems and appurtenant equipment within buildings. 5. Ordinance adopting a new Chapter 16.17 of the Palo Alto Municipal Code, California Energy Code, 2005 Edition - The 2005 California Energy Code, adopted by the California Energy Commission, is unique to California and sets forth the minimum mandatory energy efficiency requirements for all buildings and structures. DISCUSSION Typically, a new edition of the CBSC is published and adopted by the State of California every three years, based substantially on the model uniform codes. Palo Alto last adopted new building codes in 2002. However, in 2004 the Building Standards Commission opted to remain CMR:385:07 Page 2 of 5 with the 1997 edition of the Uniform Building Code (UBC) rather than switch to the 2003 editions of the International Building Code (IBC) and the International Residential Code (IRC) published by the ICC. This year, the BSC adopted and published a new edition of the CBSC based on the 2006 IBC and updated versions of other model codes. The new CBSC will become effective statewide on January 1, 2008, as published, unless local jurisdictions adopt more stringent local amendments in accordance with State law. Generally, the local amendment process requires local jurisdictions to make specific findings of fact to support each local amendment, based on climatic, geologic or topographic conditions that are unique to the jurisdiction. For Palo Alto’s proposed local amendments, these findings of fact are attached to each Ordinance where applicable. The majority of the proposed local amendments to the 2007 California Building Code are technical in nature and have been developed in concert with building officials and building code consultants from throughout the region to promote consistency across jurisdictions. A number of these amendments address aspects of the IBC that would otherwise weaken existing building standards with respect to structural analysis and seismic safety. Additionally, new repair and reconstruction standards recommended by the Association of Bay Area Governments (ABAG) are incorporated into the local amendments to meet the Federal Emergency Management Association’s (FEMA’s) eligibility requirements for post-disaster funding assistance for repairs to public and private non-profit-owned buildings damaged in disasters. Other amendments ensure consistency with provisions of the new Fire Code that are described in greater detail in a companion staff report prepared by the Fire Marshal. Finally, a number of administrative amendments are proposed to reflect Palo Alto’s current policies for building code enforcement. Few local amendments are proposed to the 2007 California Electrical and Mechanical Codes, while several are proposed to the Plumbing Code. These Plumbing Code amendments are intended to promote consistency with Palo Alto’s Sewer Use Ordinance (PAMC Chapter 16.09) and support the City’s efforts to reduce copper and other heavy metal discharges from the Wastewater Treatment Plant, in addition to water conservation, (e.g. the prohibition of single- pass cooling systems). Finally, the California Energy Code is proposed for local adoption to set the stage for future local amendments that would require increased energy efficiency standards beyond the State’s minimum requirements as a key component of the City’s evolving Green Building Program. The adoption of all of the new model codes is a significant step towards the eventual implementation of a Green Building Program since they form the foundation upon which mandatory local Green Building standards will be developed. According to the Building Standards Commission, adoption of the new state model codes will also increase the insurance industry’s Building Code Effectiveness Grading for California communities, which insurers can then use to grant premium credits for buildings constructed and enforced under the latest codes. These ratings have been downgraded in recent years because California has not adopted the latest model codes. State law requires that a noticed public hearing be held prior to the reading and adoption of any ordinance that adopts by reference a model code. Therefore, staff recommends that Council set a CMR:385:07 Page 3 of 5 enforced under the latest codes. These ratings have been downgraded in recent years because California has not adopted the latest model codes. State law requires that a noticed public hearing be held prior to the reading and adoption of any ordinance that adopts by reference a model code. Therefore, staff recommends that Council set a public hearing on these ordinances for November 13, 2007. Consistent with State law, the codes and amendments adopted by the ordinances would take effect 30 days after the second reading, which is scheduled for November 26. Thus, the new model codes and Palo Alto’s local amendments will go into effect locally in late December, just prior to the January 1, 2008 deadline, when the codes will otherwise go into effect statewide. Prior to the effective date, Building Division staff will undergo comprehensive training on the new codes and a significant outreach and public education effort aimed at the design and construction sectors that regularly work in Palo Alto will be implemented. POLICY IMPLICATIONS The State of California mandates enforcement of the updated California Building Standards Code and it will go into effect regardless of the City’s action or lack of action. As noted though, the City does have discretion to adopt local amendments to the CBSC and must adopt those amendments by January 1, 2008. RESOURCE IMPACT Resource impacts from the adoption of these ordinances are limited to staff training costs, purchasing copies of the new codes and implementation of public outreach efforts. ENVIRONMENTAL REVIEW This action is exempt from the California Environmental Quality Act. PREPARED BY: DEPARTMENT HEAD REVIEW: LARRY I.

INTRODUCED: PASSED: AYES: NOES: ABSENT: ABSTENTIONS: ATTEST: City Clerk APPROVED AS TO FORM: Mayor APPROVED: City Attorney City Manager Director of Public Works Director of Administrative Services 071001 ~S 8260596 5 * * *NOT YET APPROVED* * * Exhibit A FINDINGS FOR LOCAL AMENDMENTS TO CALIFORNIA PLUMBING CODE Section 17958 of the California Health and Safety Code provides that the City may make changes to the provisions in the uniform codes that are published in the California Building Standards Code. Sections 17958.5 and 17958.7 of the Health and Safety Code require that for each proposed local change to those provisions in the uniform codes and published in the California Building Standards Code which regulate buildings used for human habitation, the City Council must make findings supporting its determination that each such local change is reasonably necessary because of local climatic, geological, or topographical conditions. Local building regulations having the effect of amending the uniform codes, which were adopted by the City prior to November 23, !970, were unaffected by the regulations of Sections 17958, 17958.5 and 17958.7 of the Health and Safety Code. Therefore, amendments to the uniform codes which were adopted by the City Council prior to November 23, 1970, and have been carried through from year to year without significant change, need no required findings. Also, amendments to provisions not regulating buildings used for human habitation, including amendments made only for administrative consistency, do not require findings. The findings made by the Council of the City of Palo Alto in Ordinance 3215 adopting the 1979 Uniform Plumbing Code reaffirmed the findings which had been made by prior Council actions in adopting amendments to the Uniform Plumbing Code subsequent to November 23, 1970. Such findings have been reaffirmed with each successive adoption of the Uniform Plumbing Code (California Plumbing Code) as published in the California Building Standards Code, and are hereby reaffirmed and expressly made applicable to all local amendments that are hereby again adopted and carried through without significant change. 16.04.070 Section 305.4 added - Sewers Required (Palo Alto Sewer Use Ordinance referenced) Finding: This section is amended to conform to other provisions of the Palo Alto Municipal Code and is specifically authorized in Section 305.3 of the California Plumbing Code. 16.04.080 Table 6-4 (Footnote 1) amended; 16.04.090 Section 604.11 PEX, and Sub- Sections 604.11.1 PEX Fittings, and 604.11.2 Water Heater Connections adopted. Findina: These amendments allow the use of PEX, but not PE-AL-PE or PEX-AL-PEX, piping in potable water supply and distribution systems within buildings. PEX is a recognized material that is a bona-fide alternative to copper and other metallic water piping. The City’s Regional Water Quality Control Plant has, for many years, implemented programs to reduce copper and other heavy metal discharges into San Francisco Bay to comply with State Regional Water Quality Control Board requirements. These amendments are consistent with and support the City’s efforts to reduce the amount of copper influent to the Plant in accordance with the City’s approved Copper Action Plan and NPDES (Discharge) Permit under which the Plant operates. 071001 ~s 8260596 6 * * *NOT YET APPROVED** * 16.04.110 Section 701.1 amended - Materials; 16.04.120 Section 701.1.4 amended - Materials; 16.04.180 Section 1101.3 amended - Storm Drainage, General (Material Uses); and 16.04.200 Section 1105.1.2 amended - Roof Drains (Materials) Finding: These amendments prohibit the use of lead, copper and brass piping in sanitary drainage systems within buildings. The City’s Regional Water Quality Control Plant has, for many years, implemented programs to reduce copper and other heavy metal discharges into San Francisco Bay to comply with State Regional Water Quality Control Board requirements. These amendments are consistent with and support the City’s efforts to reduce the amount of copper and heavy metal influent to the Plant in accordance with the City’s approved Copper Action Plan and NPDES (Discharge) Permit under which the Plant operates. 16.04.130 Section 710.1 amended - Drainage of Fixtures Located Below the Next Upstream Manhole or Below the Main Sewer Level; 16.04.140 Section 714.4 amended - Damage to Public Sewer or Private Sewage System (Commercial Food Waste Grinders Prohibited); 16.04.150 Section 719.7 added - Cleanouts; and 16.04.170 Section 1014.1.3 amended - Food Waste Disposal Units and Dishwashers Finding: These amendments are required by the location of the City of Palo Alto between the Santa Cruz Mountain foothills and the San Francisco Bay, and the presence of several substantial creeks flowing through highly developed residential, urban and industrial areas. The City operates its own sanitary sewer collection system and Regional Water Quality Control Plant and is subject to State and Federal laws regarding both point and non-point source discharges. These amendments are intended to comply with State Water Resources Control Board requirements to minimize sanitary sewer overflows caused by blockages in the sewer system and protect the various creeks, the San Francisco Bay and Palo Alto residents from unnecessary sewage spills and threats to public health. 16.04.160 Section 808.0 amended - Single Pass Cooling Water Systems Prohibited Finding: This amendment promotes water conservation by prohibiting potable water from being used solely for the purpose of cooling appliances and other mechanical systems. This amendment is necessitated by local climatic conditions rendering potable water as a scarce and valuable resource. 16.04.190 Section 1101.9 amended -Filling Stations and Motor Vehicle Washing Establishments Finding: This amendment prohibits the paved areas of public filling stations from draining towards sumps and gratings that could otherwise be connected to the sanitary sewer system, which, in addition to polluting the sanitary sewer, could cause explosions or other hazardous events. The amendment is consistent with Best Management Practices contained within the City’s Storm Water Pollution Prevention Plan as well as statewide best practice guidelines for the proper design of motor vehicle fueling stations. 071001 qis 8260596 7 ***NOT YET APPROVED*** ATTACHMENT B ORDINANCE NO.

Sections 17958.5 and 17958.7 of the Health and Safety Code require that for each proposed local change to those provisions in the uniform codes and published in the California Building Standards Code which regulate buildings used for human habitation, the City Council must make findings supporting its determination that each such local change is reasonably necessary because of local climatic, geological, or topographical conditions.

Therefore, amendments to the uniform codes which were adopted by the City Council prior to November 23, 1970, and have been carried through from year to year without significant change, need no required findings. Also, amendments to provisions not regulating buildings used for human habitation do not require findings. The findings made by the Council of the City of Palo Alto in Ordinance 2600 adopting the 1968 National Electrical Code and the findings adopted by the Council in Ordinance 2811 adopting the 1971 National Electrical Code, have been reaffirmed with each successive adoption of the National Electrical Code (California Electrical Code) as published in the California Building Standards Code, and are hereby reaffirmed and expressly made applicable to such changes as are hereby adopted, readopted, amended or carried through without significant change.
