A General lFmdmes The Dublm CIty CouncIl makes the follOWIng general findmgs regardmg local
clImatIc, geologiC, and topographICal condItlOns, whIch the CIty CouncIl finds necessItate the local
modIficatIOns to the CalIfornIa BUIldmg Standards Code set forth below
1 Local chmatlc conditIOns Include a low amount of average yearly ramfall, whIch tends to be
concentrated from October through Apnl From May through September, a dry penod occurs where
datly temperatures rematn hIgh, and there IS httle measurable preCIpitatIOn In addItion, the local
chmate frequently mcludes high wmds whIch sweep down through the valley
In developed areas of the City, fires can occur III bUIldIngs, rubbIsh, automobIles, and grass fires on
vacant lots In the undeveloped areas of the City, there IS a nsk of large brush and grass fires If a
fire occurs m eIther a developed or undeveloped area of the CIty, the local dry condltlOns combmed
WIth hIgh wmds creates the nsk of a potentIal fire storm
In addItIon, local resldentIal development IS occUITlng In prevIOusly undeveloped areas adjacent to
WIld fire hazard areas These new developments mcrease the chance of fire whIle SImultaneously
bemg located further from fITe statIOns, delaymg cntIcal response tImes
2 Local geographIcal condItIons Include a nsk of earthquake A number of earthquake faults are
located eIther WithIn or III close proxlmIty to the Clty Those With the most dIrect and potentially
destructive Impact are the San Andreas, Calaveras, Hayward, Greenvtlle and Concord-Green Valley
Faults History of earthquake activIty mdIcates that there IS a hkelthood of a major earthquake m the
area
In the event of an earthquake, damage to structures can be expected In reSIdential and commerCIal
areas, thIS could mclude SIgnIficant damage or collapse of bUIldmgs Secondary Impacts could
mclude ruptured electnc or gas connectIons and/or breaks In water dIstrIbution lines The potentIal
for a major seIsmIC event would create a City-WIde demand for emergency response and fire
protectIOn servIce which would exceed staff response capaCIty
3 Local topographical condItIons Include hIlls on the western and eastern boarders and flat area In the
center of the City Interstate 680 dIVIdes the City mto two sectIOns, and CirculatIon between areas of
the City rely on freeway overpasses In addItIOn, local traffic must also pass over ratlroad tracks,
creeks, and bndges (to cross arroyos)
Durmg peak a m and p m traffic perIods, the CIty expenences heavy traffic congestIon at key
IntersectIons, and near many freeway on-ramp and off-ramps In the event of an aCCident or
emergency at one of these key IntersectIOns, bndges, or other CIrculatIon comdors, sectIons of the
City could become Isolated and response tImes Increased beyond Ideal levels
4 Based on the local clImatIC, geographIcal, and topographIcal condItlOns outlIned above, there IS a
real nsk that emergency response could be slgmficantly delayed In the event of an aCCident or
emergency Therefore, It IS necessary to address thIS problem through the reqUirement of addItIonal
mitigatIOn measures to (I) prevent the chance of aCCident or Injury by requIrIng standards more
stnngent than reqUIred by the current codes, and (n) requmng addItIOnal bUIlt-m automatic fire
protectlOn systems which WIll proVIde for early detectIon and InItIal fire control
