Ordinance No. 1432 <br />Page 2 <br /> <br /> 1. The climatic conditions within the City of <br /> Pleasanton are such that: <br /> <br /> a. Extensive fire damage, potential loss of life <br /> and injury to fire personnel result from the <br /> limited effectiveness and capabilities of the <br /> fire department to control free burning roof <br /> fires, fanned by high winds which require <br /> extraordinary tactical measures, which in <br /> themselves cause early exhaustion of <br /> firefighters. <br /> <br /> b. Extensive fire damage due to exposure problems <br /> compounded by high winds reduce the <br /> effectiveness of hose streams through <br /> disintegration, lack of reach and misdirection. <br /> <br /> c. Extensive fire damage caused by an exterior roof <br /> fire spreading to and involving nearby dry <br /> vegetation, other buildings or objects results <br /> in multiple fires due to dryness, high <br /> temperatures and/or winds. <br /> <br /> d. The mean annual rainfall average is 17 inches <br /> which primarily occurs starting in October and <br /> ending in April. The mean daily maximum <br /> temperature is 73 degrees Fahrenheit with hot, <br /> dry summer days, which bring temperatures to the <br /> 100 degree Fahrenheit mark. The mean daily <br /> minimum temperature is 42 degrees Fahrenheit <br /> with cold winter nights, which bring <br /> temperatures below freezing. Prevailing winds <br /> are out of the southwest and range from calm and <br /> gusty at 10-15 knots in the A.M. and changing to <br /> 18-20 knots in the P.M., with highs that range <br /> between 30-55 knots. These climatic conditions <br /> create the potential for extensive fire damage, <br /> loss of life and injury to firefighters, as <br /> shown in the findings above. <br /> <br /> 2. The geological conditions within the specified areas <br /> of the City of Pleasanton are such that: <br /> <br /> a. Extensive fire damage and potential loss of life <br /> result from the limited effectiveness and <br /> capabilities of the fire department, due to <br /> reduced and delayed response of fire companies <br /> on arterial routes obstructed by collapsed <br /> overpasses and bridges and/or landslides caused <br /> by earthquakes and/or unstable soils. <br /> <br /> <br />
