EXHIBIT E TO RESOLUTION NO. 2010 -131 <br /> FINDINGS AND DETERMINATION THAT CHANGES <br /> OR MODIFICATIONS TO THE 2009 UNIFORM PLUMBING CODE <br /> AND THE CALIFORNIA PLUMBING CODE, <br /> 2010 EDITION, PERTAINING TO THE DELETION OF <br /> ACRYLONITRILE- 13UTADIENE- STYRENE AND POLY -VINYL <br /> CHLORIDE FROM USE F014 DRAIN WASTE AND VENT <br /> SYSTEMS, ARE REASONABLY NECESSARY BECAUSE OF <br /> LOCAL CONDITIONS <br /> 1. In connection with the adoption by reference of the Uniform Plumbing Code, <br /> 2009 Edition as amended by the State of California in that document entitled "The Califomia <br /> Building Standards Code," it is hereby expressly found and determined that the following change <br /> to the California Building Standards Code is reasonably necessary because of local climatic, <br /> geological or topographical conditions: <br /> All reference to acrylonitrile- butadiene - styrene (ABS) and poly -vinyl chloride <br /> (PVC) piping, fittings and valves for use in drain, waste and vent (DWV) systems, <br /> is hereby deleted from the UPC. The use of ABS and PVC for drain, waste and <br /> vent systems is expressly disallowed in the City of San Leandro. <br /> 2. The aforesaid local amendment is reasonably necessary in order to lessen the <br /> threat to life, safety and property represented by certain local climatic, geographical and <br /> topographical conditions existing in the City of San Leandro. <br /> 3. The aforesaid local amendment is enacted pursuant to the authority of Section <br /> 17958.5 of the California Health and Safety Code, for the purpose of addressing the aforesaid <br /> conditions which are more specifically described as follows: <br /> (a) The City of San Leandro lies in the near vicinity of the Hayward Fault and <br /> in fact, a substantial portion of the residential area of the City lies within <br /> the Alquist- Priolo Act Special Studies Zone, requiring special geologic <br /> studies prior to development. This increases the likelihood of seismic <br /> disturbances of substantial magnitude occurring and causing consequent <br /> damage. Such damage is often accompanied by structural fire. Because <br /> plastic pipe is combustible, emits toxic gases and acids and generates large <br /> amounts of smoke, its presence would increase the threat to life and <br /> property in the event of a seismic disturbance. <br /> (b) The travel time to a fire or other emergency within San Leandro may be <br /> impeded by the following conditions: <br /> 1 <br />
