and a natural creek, divide the City into numerous sections, and equipment <br />responding to emergencies face potential delays and obstruction of access <br />in crossing these barriers. <br /> <br />(2) San Leandro lies in the path of two major water reservoirs which, upon <br />failure, would inundate a large portion of the City, further delaying the <br />response to a fire or other emergency. <br /> <br />(3) A growing community of single-family and multi-family dwellings <br />presently exists on the easterly side of Highway 580, which is itself a <br />potential physical barrier impeding response to a fire or other emergency. <br /> <br />(4) The two major north-south emergency response routes aside from the <br />freeways are dependent upon bridges spanning San Leandro Creek. Failure <br />of these bridges would isolate a heavily populated section of the City north <br />of the creek. <br /> <br />In an event, gas presents an extreme danger to life and property and could <br />cause loss of life, damage to property and destruction of infrastructure. <br /> <br />c) A large area of potential residential development in the westerly portion of the <br />City, adjacent to the Bay, is potentially subject to liquefaction which may cause a <br />loss of lateral support for gas pipe, resulting in its failure. Liquefaction also often <br />results in a greater degree and different form of differential movement than occurs <br />elsewhere, which may cause excessive strain on gas pipe. <br /> <br />d) High wind conditions normally exist in the hillside, shoreline areas and the City, <br />increasing the potential for fire spread if there is a gas pipe failure. <br /> <br />
