FINDINGS FOR LOCAL MODIFICATIONS TO THE 2010 EDITIONS OF THE /
CALIFORNIA FlRE CODE, CALlFORNiA BUILDING CODE, CALIFORNIA RESIDENITAL
CODE, CAUFORNIA ELECTRICAL CODE, CALIFORNlA PLUMBING CODE, CALIFORNIA
MECHANICAL CODE, CALIFORNIA GREEN BUILDING CODE AS SET FORTH IN THE
2010 CALIFORNIA BUILDING STANDARDS CODE
A. General Findinqs. The Dublin City Council makes the following general findings regarding
local climatic, geologic, and topographical conditions, which the City Council finds
necessitates the local modifications to the California Building Standards Code set forth
below:
Local climatic conditions include a low amount of average yearly rainfall, which tends to
be concentrated from October through April. From May through September, a dry period
occurs where daily temperatures remain high and there is little measurable precipitation.
In addition, the local climate frequently includes high winds which sweep down through
the valley. As a result of the high summer temperatures, average load demand and peak
load demand of energy used in Dublin are important factors impacting public safety and
creating the potential for adverse economic impacts due to power outages or power
reductions (i.e. "brownouts"). As a result of the low precipitation, the area is subject to
occasional drought.
In developed areas of the City, fires can occur in buildings, rubbish, automobiles, and
grass fires on vacant lots. In the undeveloped areas of the City, there is a risk of large
brush and grass fires. !f a fire occurs in either a developed or undeveloped area of the
City, the local dry conditions combined with high winds, creates the risk of a potential fire
storm.
In addition, focal residential development is occurring in previously undeveloped areas
adjacent to wild fire hazard areas. These new developments increase the chance of fire
while simultaneously being located further from fire stations, delaying critical response
times.
2. Local geographical conditions include a risk of earthquake. A number of earthquake
faults are located either within or in close proximity to the City. Those with the most
direct and potentially destructive impact are the San Andreas, Calaveras, Hayward,
Greenville and Concord-Green Valley Faults. History of earthquake activity indicates that
there is a likelihood of a major earthquake in the area.
In the event of an earthquake, damage to structures can be expected. In residential and
commercial areas, this could include significant damage or collapse of buildings.
Secondary impacts could include ruptured electric 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 into two sections, and
circulation between areas of the City rely on freeway overpasses. In addition, local traffic
must also pass over railroad tracks, creeks, and bridges (to cross arroyos).

~~,
During peak a.m. and p.m. traffic periods, the City experiences 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, bridges, or other circulation
corridors, sections of the City could become isolated and response times increased
beyond ideal levels.
4. Based on the local climatic, geographical, and topographical conditions outlined above,
there is a real risk that emergency response could be significantly 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 stringent than required by the current codes; and (ii)
requiring additionaf built-in automatic fire protection systems which will provide for early
detection and initial fire control.
B. Specific Findings: The Dublin City Council makes the following specific findings, which, in
addition to the general findings regarding local climatic, geologic, and topographical
conditions set forth above, the City Council finds necessitate the local modifications to the
California Building Standards Code set forth below:

FINDING: The amendment is needed due to local climatic and topoqraphical
conditions.
This modification was necessary because the City of Dublin has a drv
period of at least five months each vear. Additionally, The area is subiect to
occasional drouqht. Because of drvness, a rapidly burninq qrass fire or
exterior buildinq fire can quickly transfer to other buildinqs. These

such piping shall be installed in accordance with the following requirements:
FINDINGS The amendment is needed due to local qeoloqical conditions.
This section eliminates water pipinq in or under concrete floor slabs within a
buildinq. This amendment is necessary for the followinq reasons:
(1) Most of the surface soits in the Citv of Dublin are relatively younq and
unconsolidated sedimentarv ma#erials formed from a wide variety of parent
materials. The varving chemical composition, deqree of weatherinq and the
relativelv acid environment have created soils of varvinq types, which are
particularly corrosive in nature.
(2~ Much of the surface soil in the City of Dublin is hiqhly expansive (i.e., shrink-
swell behavior) and have low bearinq strenqth.
(3) There are two types of expansive soils in the area:
a. the orqanic siltv clavs which are the recent bav muds; and
b. the plastic siltv clavs which weather from the shale found in the hills
surroundinq the Citv of Dublin
(4) The loca! climate is characterized bv markedlv delineated rainv and drv
seasons, which tend to maximize the expansive characteristics of soil.
(5) Some parts of the Citv of Dublin have hard water, which is corrosive to
ferrous pipe.
(6) The qroundwater table is unusuallv hiqh in many places.
(7) The Citv of Dublin is a hiqhly active seismic area.

unless otherwise indicated in this code, within the City.
B. It is not the intent that this code substitute or be identified as meeting the certification
requirements of any green building program.
C. Sections 7.94.080 through 7.94 120, shall apply only to new residential development
projects in excess of finrenty (20) residential units.
