<br />
<br />PURPOSE
<br />
<br />'1110 purposc of the Public Safcty Elemcnt is to I'rovidc information, I'olicics, and I'ro!,>1'ams dircctcd
<br />toward reducing the potential for human injury and loss of life, and to minimize property datnagc and
<br />cconomic and social disruption duc to natural and human-madc hazards.
<br />
<br />RISKS OF HAZARDS!
<br />
<br />All urban ateas in California arc subjcct to a varicty of naturally-occurring hazards as wcll as hazards
<br />causcd by human activitics. Risks to lifc and propetty within thc I'lanning Arca arc most commonly
<br />Posed by geology (carthquakcs'- landslidcs'- ....n-:+-firp. flood. ~n!iM1nn tr~in ~nd ~lIt() ~rr;{l('nt". and the
<br />" ~, ....L'-./, , ,
<br />accidental dischatgc of hazardous matcrials. None of thcse hazards can bc avoidcd entirely or
<br />mitigatcd coml'lctely. Howcvcr, potcntially dcvastating impacts I'rcscntcd by such hazards can bc
<br />rcduccd thtough thc rccognition of thc safcty risks and thc application of safcty standards dcsigncd to
<br />ptotect lifc and I'rol'crty to thc grcatcst fcasible cxtent.
<br />
<br />TI,C I'ublic Safcty Elcmcnt contains policics and programs which cstablish "safcty" criteria for
<br />evaluating ncw dcvelol'mcnts and which establish standards for thc City's emergcncy responsc scrviccs
<br />and ptograms to ptotect lifc and propcrty.

<br />Geologic Setting
<br />
<br />'111C Plcasanton Planning Arca is locatcd within thc Amador Vallcy, which is part of thc Coast Rangc
<br />geologic province of California. --nlC Coast Range province is a large area of folded and faulted rocks
<br />situatcd along thc western cdgc of thc North Amcrican continent. Thc Amador Vallcy is a deprcssion
<br />in this tock formation which joins thc San Ramon Vallcy to thc north with thc Livcrmorc Vallcy to thc
<br />cast. 'Il,C geologic conditions which havc formcd the topogral'hy surrounding Plcasanton arc the rcsult
<br />of a global I'attern of moving contincntal I'latcs which havc shapcd thc carth's outcr surfacc ovcr
<br />hundreds of millions of ycars.
<br />
<br />'l1,c undcrlying gcology of scdimcntary rock in thc Pleasanton Ridgc and thc Southcast Hills, the thick
<br />dCl'osits of unconsolidated scdimcnt on thc Valley floor, and arcas of oldcr landslidc dcposits are
<br />factors, which; along with thc ptoximity of scvcral carthquake faults, crcatc a geologic sctting
<br />susceptible to a number of geologic hazards. Ttrcsr-'I1,i", Fl,..fnpnt h.u..u'-.b .au,; J(';M...L~LI..":J lJI~l.::n)
