Ordinance No. 1542 <br /> <br /> b. Extensive fire damage and potential loss of <br /> life result from the limited and/or delayed <br /> response of the fire department, due to <br /> dispersion, to multiple fires caused by <br /> escaping natural gas or electrical <br /> transmission equipment damaged by earthquakes. <br /> <br /> c. The City of Pleasanton has the potential to be <br /> affected by large seismic movement of major <br /> area and nearby faults. These include the <br /> faults of Greenville, Calaveras, Hayward and <br /> the most well-known San Andreas Fault. Also <br /> of note are the smaller faults of Livermore, <br /> Tesla and Las Positas. The major area faults <br /> have shown some activity within the past few <br /> years. The probability of additional seismic <br /> activity in the Livermore-Amador Valley has <br /> been indicated by seismologists. The activity <br /> to expect would most likely range between 5 <br /> and 7 on the Richter Scale. Because of this <br /> geological threat, the potential for extensive <br /> fire damage and loss of life is shown in the <br /> findings above. <br /> <br /> 3. The topographical conditions within the specified <br /> areas of the City of Pleasanton are such that: <br /> <br /> a. Extensive fire damage results from multiple <br /> fires involving wood shake or shingle building <br /> exteriors ignited because of exposure to fires <br /> which spread beyond the building of origin. <br /> <br /> b. Extensive fire damage and potential for loss <br /> of life result from the inability of the fire <br /> department to gain rapid access to fires due <br /> to terrain, slopes, landscaping, size of <br /> buildings, and relationship to other buildings <br /> in time to stop a free burning roof fire from <br /> consuming the entire roof and attic area. <br /> <br /> c. The City of Pleasanton is primarily located <br /> within a valley with a mountain range to the <br /> west (some of which is in the City). This <br /> range reaches an elevation of approximately <br /> 1,000 feet. To the east and southeast, there <br /> is hilly terrain which reaches 700 feet of <br /> elevation and there are flatland areas <br /> bordering the City which are agricultural in <br /> nature, and highly flammable grain and hay <br /> crops abound. All of these areas have been <br /> determined, by the California Department of <br /> Forestry, to present a fire hazard severity of <br /> <br /> - 3 - <br /> <br /> <br />
