(1) Three major railway lines, the elevated BART line, three major freeways and a natural creek, divide the City into numerous sections, and equipment responding to emergencies face potential delays and obstruction of access in crossing these barriers. (2) San Leandro lies in the path of two major water reservoirs which, upon failure, would inundate a large portion of the City, further delaying the response to a fire or other emergency. (3) A growing community of single- family and multi- family dwellings presently exists on the easterly side of Highway 580, which is itself a potential physical barrier impeding response to a fire or other emergency. (4) The two major north -south emergency response routes aside from the freeways are dependent upon bridges spanning San Leandro Creek. Failure of these bridges would isolate a heavily populated section of the City north of the creek. In the event of fire, toxic gases and acids emitted by plastic pipe and the smoke generated by plastic pipe, represent an increased life hazard and since most Toss of life in fires is from asphyxiation, a rapid response by emergency equipment becomes more critical. (c) All drain and waste pipes flow into the San Leandro Sewage Treatment Plant. Any chemical reaction between plastic pipe and the waste flowing through it, may produce contaminants, threatening the biological process of the Treatment Plant itself and in turn thereby threatening the marine life in the San Francisco Bay. (d) A large area of potential residential development in the westerly portion of the City, adjacent to the Bay, is potentially subject to liquefaction which may cause a loss of lateral support for plastic pipe, resulting in its failure. Liquefaction also often results in a greater degree and different form of differential movement than occurs elsewhere, which may cause excessive strain on plastic pipe. (e) High wind conditions normally exist in the hillside and shoreline areas of the City, increasing the potential for fire spread. The presence of plastic pipe increases the life hazard.
