The aforesaid local amendments are 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. <br />(b) Recent earthquake activities, including the 1989 Loma Prieta and the 1994 <br />Northridge earthquakes, have indicated the lack of adequate design and <br />detailing as a contributing factor to damages that reduced the protection of <br />the life -safety of building occupants. <br />(c) The underlying soils are subject to liquefaction and amplification of <br />seismic energy.
