Climate Zone 3 incorporates communities near the coast from Marin County to southern Monterey County including Los Altos Hills. The Town experiences precipitation ranging from 18 to 22 inches per year with an average of approximately 20 inches per year. Ninety-five percent of precipitation falls during the months of November through April, leaving a dry period of approximately six months each year. Ordinance 589 Page 1 Relative humidity remains moderate most of the time and temperatures average 80 degrees the mid -50s in winter. These climatic conditions along with the greenhouse emissions generated from residential structures requires exceeding the energy standards for building construction established in the 2019 California Building Standards Code. The Town's City Council also adopted a Climate Action Plan that has a goal of reducing greenhouse gas emissions below 1990 levels by the year 2030. In order to achieve and maintain this goal, the Town needs to adopt policies and regulations that reduce the use of fossil fuels that contribute to climate change, such as natural gas in buildings. 2. Geologic: The Town of Los Altos Hills is subject to earthquake hazard caused by its proximity to San Andreas fault. This fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta Earthquake, up the San Francisco Peninsula eventually moving offshore at Daly City near Mussel Rock. This fault system is considered a major Northern California earthquake faults which may experience rupture at any time. Thus, because the City is within a seismic area which includes these earthquake faults, the modifications and changes cited herein are designed to better limit property damage as a result of seismic activity. 3. Topographic: The Town of Los Altos Hills consists of ridgelines, rolling foothills and deep wooded canyons that affect climate conditions resulting in increased use of heating and cooling systems and the trapping of potential greenhouse gases in the valley floors. WHEREAS, in accordance with Health and Safety Code section 17958.7, the City Council hereby finds that each of the above findings is applicable to each of the modifications to the 2019 Edition of the California Energy Code described in this ordinance; and WHEREAS, the City Council of the Town of Los Altos Hills finds that this project is exempt from the provisions of the California Environmental Quality Act ("CEQA"), pursuant to Section 15061(b)(3) of the CEQA Guidelines, because it can be seen with certainty that there is no possibility that the ordinance will have a significant effect on the environment.
