In addition, local residential development is occurring in <br />previously undeveloped areas adjacent to wild fire hazard <br />areas. These new developments increase the chance of fire <br />while simultaneously being located further from fire <br />stations, delaying critical response times. <br /> <br />2. Local geographical conditions include a risk of <br />earthquakes. A number of earthquake faults are located <br />either within or in close proximity to the City. Those with <br />the most direct and potentially destructive impact are the <br />San Andreas, Calaveras, Hayward, Greenville and <br />Concord-Green Valley Faults. History of earthquake <br />activity indicates that there is a likelihood of a major <br />earthquake in the area. <br /> <br />In the event of an earthquake, damage to structures can be <br />expected. In residential and commercial areas, this could <br />include significant damage or collapse of buildings. <br />Secondary impacts could include ruptured electric or gas <br />connections and/or breaks in water distribution lines. The <br />potential for a major seismic event would create a City- <br />wide demand for emergency response and fire protection <br />service which would exceed staff response capacity. <br /> <br />3. Local topographical conditions include hills on the <br />western boarder and flat area on the eastern boarder. <br />Interstate 680 divides the City into two sections, and <br />circulation between areas of the City rely on freeway <br />overpasses. In addition, local traffic must also pass over <br />railroad tracks, creeks, and bridges (to cross arroyos). <br /> <br />During peak a.m. and p.m. traffic periods, the City <br />experiences heavy traffic congestion at key intersections, <br />and near many freeway on-ramp and off-ramps. In the <br />event of an accident or emergency at one of these key <br />intersections, bridges, or other circulation corridors, <br />sections of the City could become isolated and response <br />times increased beyond ideal levels. <br /> <br />4. Based on the local climatic, geographical, and <br />topographical conditions outlined above, there is a real risk <br />that emergency response could be significantly delayed in <br />the event of an accident or emergency. Therefore, it is <br /> 2 <br /> <br /> <br />
