The City Council of the City of Calistoga does ordain as follows: SECTION ONE: Adoption The City Council of the City of Calistoga adopts this Ordinance repealing Title 8, Chapter 8.08 (Gasoline and Liquefied Petroleum Gases) and repealing Title 15 (Uniform Codes) of the Calistoga Municipal Code, and adopting a new Title 15 to include the 2007 California Building Standards Code, Title 24 of the California Code of Regulations, as adopted by the State Building Standards Commission as follows: 2007 California Administrative Code (Part 1 of Title 24); 2007 California Building Code with certain appendices (Part 2 of Title 24), based on the 2006 International Building Code (IBC); 2007 California Electrical Code with certain appendices (Part 3 of Title 24), based on the 2005 National Electrical Code (NEC); 2007 California Mechanical Code with certain appendices (Part 4 of Title 24), based on the 2006 Uniform Mechanical Code (UMC); 2007 California Plumbing Code with certain appendices (Part 5 of Title 24), based on the 2006 Uniform Plumbing Code (UPC); 2007 California Energy Code with certain appendices (Part 6 of Title 24); 2007 California Historical Building Code with certain appendices (Part 8 of Title 24); 2007 California Fire Code with certain appendices (Part 9 of Title 24), based on the 2006 International Fire Code (IFC); 2007 California Existing Building Code with certain appendices (Part 10 of Title 24), based on the 2006 International Existing Building Code (IEBC); 2007 California Referenced Standards (Part 12 of Title 24); Uniform Code for Abatement of Dangerous Buildings (UCADB), 1997 Edition; and Uniform Housing Code (UHC), 2006 Edition; all as promulgated and published by the International Code Council (ICC).

Page 3 of 32 SECTION TWO: Findings A. The City Council of the City of Calistoga finds that in order to best protect the health, safety and welfare of the citizens of the City of Calistoga, the standards of building within the City must conform with State law except where local conditions warrant more restrictive regulations. B. Pursuant to Section 17958 of the California Health and Safety Code, the governing body of the City of Calistoga, in its ordinance adopting the State Building Standards Code and uniform industry codes, may establish amendments which are more restrictive in nature than those regulations adopted by the State of California commonly referred to as Title 24 of the California Code of Regulations. Based on the materials presented and by the recommendation of the Building Official, the Fire Chief, and the Planning & Building Director, the City Council further finds that it is necessary to make modifications to the California Building Standards Code and to adopt or not adopt certain appendices to the Code. Under the provisions of Section 17958.5 of the California Health and Safety Code, local amendments shall be based on climatic, geographical and topographical conditions. As such, the City Council finds that the following local conditions exist: 1. Climate. The City, on an average, experiences an approximate annual rainfall of 38 inches. This rainfall can normally be expected between October and April. During the winter months, the City may experience periods of heavy rain, which causes local flooding, erosion and contributes to slope instability. Winter storms are often accompanied by high winds, which have uprooted trees and damaged power lines. The City has also experienced periodical days of heavy fog, which could delay the response time for fire fighting apparatus, and prevent early discovery of structure fires. Wind is a factor in the spread of fire in that burning embers are carried with the wind to adjacent exposed areas. Calistoga has a characteristic southerly wind, which originates from the San Francisco Bay and becomes a factor in the control of fires. Further, in the dry season, Calistoga experiences an occasional north wind of significant velocity, which is recognized by Fire Officials to be a significant concern with regard to fire spread. During the dry period, temperatures range from 70 degrees to over 100 degrees. These temperatures are often accompanied by a wildland-urban interface, creating a hazardous fire condition. With increased development spreading into the brush covered foothill areas, wind driven fires could have severe consequences, as has been demonstrated on several occasions throughout the State. 2. Geographical. The City is susceptible to seismic hazards resulting from movement along any one of several known faults in the area. The most serious direct earthquake hazard threat is from the damage or collapse of

Page 4 of 32 buildings and other structures due to ground movement. In addition to damage caused by earthquakes, there is a possibility of earthquake-induced landslides. Fire is often the major form of damage resulting from earthquakes. Most earthquake-induced fires start because of damage to gas lines, power lines or heat producing appliances. Such fires expose residential and other development within the City to an increased risk of conflagration. In addition, unstable slopes have been identified in the City, which present a significant potential for landslides. In the event of a major earthquake or landslide, many areas of the City may not be accessible to emergency equipment and, if bridges or roads are damaged, the City may be isolated from outside assistance. Several areas within the City of Calistoga offer poor access for the delivery of public safety services because of the severity of slopes and the existence of natural barriers such as the Napa River and its tributaries such as Garnett Creek and Cyrus Creek. 3. Topographical. The City borders include hilly terrain on the southwest portions of the City. The roadway systems in these hills are designed around the lay of the land with respect to narrow, winding and steep access ways. The grades of these roadways sometimes exceed 25% and road widths of less than 12 feet are not uncommon. The Napa River and other small water ways run directly through the City and could impact emergency response during disasters. The water supply within the City is directly affected by the topographical layout. The water distribution system consists of pressure zones, which carry water by gravity from various reservoirs. Water flow within the City can vary from less than 100 gallons per minute to flows in excess of 1,000 gallons per minute. This wide variation causes major problems to development as well as to fire suppression efforts. The hilly terrain contributes to drainage, erosion and slope instability problems for some development. SECTION THREE: Title 8, Chapter 8.08 repealed. Chapter 8.08 Gasoline and Liquefied Petroleum Gases of Title 8 (Health and Safety) of the Calistoga Municipal Code is hereby repealed in its entirety. SECTION FOUR: Title 15, Uniform Codes, repealed and adopted. Title 15 Uniform Codes of the Calistoga Municipal Code is hereby repealed and adopted to read as follows:
