FINDINGS FOR LOCAL MODIFICATIONS TO THE 2013 EDITIONS OF THE
CALIFORNIA FIRE CODE, CALIFORNIA BUILDING CODE, CALIFORNIA RESIDENTIAL
CODE, CALIFORNIA ELECTRICAL CODE, CALIFORNIA PLUMBING CODE, CALIFORNIA
MECHANICAL CODE, CALIFORNIA GREEN BUILDING CODE AS SET FORTH IN THE
2013 CALIFORNIA BUILDING STANDARDS CODE
A. General Findings. 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:
1. 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. If 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, local 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. This potential problem can be mitigated by requiring initial fire control through the
installation of automatic fire protection systems.
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. The largest recorded earthquake
in this immediate area occurred on the San Andreas Fault on October 17, 1989, a 7.1
magnitude. This area had a sequence of earthquakes on the Greenville Fault in January
and February of 1980; these earthquakes had a magnitude of 5.5 to 5.9 on the Richter
Scale. The U.S. Geological Survey (USGS) has identified a 70% probability of a major
earthquake occurring in the region within the next 30 years. Recent earthquake damage
studies, including the 1994 Northridge earthquake, have indicated the lack of adequate
design and detailing as a contributing factor to damages that reduced the protection of
the life-safety of building occupants.
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.
Page 1 of 41 EXHIBIT A
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. This potential problem can be mitigated by requiring initial fire control
through the installation of automatic fire protection systems.
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. Again, this potential problem can be mitigated by requiring initial fire
control through the installation of automatic fire protection systems.
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 additional 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:
1. California Fire Code.

`Editor's Note: Figure 15-1 is on file in the office of the City Clerk.
FINDING: The amendment is needed due to local climatic and topographical
conditions.
This modification was necessary because the City of Dublin has a dry
period of at least five months each year. Additionally, The area is subject to
occasional drought. Because of dryness, a rapidly burning grass fire or
exterior building fire can quickly transfer to other buildings. These
modifications are consistent with the Fire Authority having jurisdiction.
7.32.200 Table 1607.1, Chapter 16, Uniform and concentrated live loads-Amended.
Table 1607.1 is amended by adding a new Footnote 0 to read:
O. Bridges for vehicular traffic shall be designed for H2O loading as designated by the
American Association of State Highway Officials.
Page 13 of 41
FINDING: The amendment is needed due to local geological, climatic and
topographical conditions.
This modification was necessary because bridges were not addressed by
the Building Code. Additionally do to the City's terrain a number of bridges
and overpasses may be required.
7.32.220 Section 1705.3, Exception 1, Chapter 17, Concrete Construction -Amended
Section 1705.3, Exception 1 is amended to read:
1. Isolated spread concrete footings of buildings three stories or less above grade
plane that are fully supported on earth or rock, where the structural design of the
footing is based on a specified compressive strength, f c, no greater than 2,500
pounds per square inch (psi) (17.2 Mpa).
FINDINGS: The amendment is needed due to local geological, climatic and
topographical conditions.
The San Francisco Bay area region is densely populated and/or located in an
area of high seismic activities as indicated by United States Geological
Survey and California Division of Mines and Geology. Recent earthquake
activities, including the 1989 Loma Prieta earthquake, have indicated the
lack of adequate design and detailing as a contributing factor to damages
that reduced the protection of the life-safety of building occupants. The City
of Dublin is a densely populated area having buildings constructed near
potentially active faults. The Association of Bay Area Governments (ABAG)
roughly estimates the probability of a serious earthquake along the Hayward
Fault as one-in-four in the next 30 years, while the USGS predict the
probability of a powerful quake in the next 30 years at 62%. The proposed
modification to ensure that the design of slender wall must satisfy both
strength and serviceability requirements need to be incorporated into the
code to assure that new buildings and additions to existing buildings are
designed and constructed in accordance with the scope and objectives of
the International Building Code.
7.32.230 Section 1905.1.8, Chapter 19, ACI 318, Section 22.10-Amended
Section 1905.1.8, is amended to read:
22.10 - Plain concrete in structures assigned to Seismic Design Category C, D, E or F.
22.10.1- Structures assigned to Seismic Design Category C, D, E or F shall not have
elements of structural plain concrete, except as follows:
(a) Isolated footings of plain concrete supporting pedestals or columns are permitted,
provided the projection of the footing beyond the face of the supported member does
not exceed the footing thickness.
Exception:
In detached one and two-family dwellings, three stories or less in height, the
projection of the footing beyond the face of the supported member is permitted to
exceed the footing thickness.
Page 14 of 41
(b) Plain concrete footing supporting walls are permitted, provided the footings have at
least two continuous longitudinal reinforcing bars. Bars shall not be smaller than No.
4 and shall have a total area of not less than 0.002 times the gross cross-sectional
area of the footing. A minimum of one bar shall be provided at the top and bottom of
the footing. Continuity of reinforcement shall be provided at corners and
intersections.
Exception:
In detached one and two-family dwellings, three stores or less in height and
constructed with stud bearing walls, plain concrete footings—with at least two
continuous longitudinal reinforcing bars not smaller than No. 4 are permitted to
have a total area of less than 0.002 times the gross cross-sectional area of the
footing.
FINDINGS: The amendment is needed due to local geological, climatic and
topographical conditions.
This amendment addresses the problem of poor performance of plain or
under reinforced concrete footings during a seismic event. This amendment
reflects the recommendations by the Structural Engineers Association of
Southern California (SEAOSC) and the Los Angeles City Joint Task Force
that investigated the poor performance of plain and under-reinforced
concrete footings observed in the 1994 Northridge earthquake.
The San Francisco Bay area region is densely populated and/or located in an
area of high seismic activities as indicated by United States Geological
Survey and California Division of Mines and Geology. Recent earthquake
activities, including the 1989 Loma Prieta earthquake, have indicated the

7.32.240 Section 2308.9.3, Chapter 23, Bracing, Items 1 and 5-Deleted.
Section 2308.9.3, Items 1 and 5 are deleted.
FINDING: The amendment is needed due to local geological conditions.
This section deletes the use of Let-in-bracing and gypsum board for lateral
bracing. This deletion is necessary because the City of Dublin is located in
Seismic Zone D and E. Gypsum wallboard has performed poorly during
recent California seismic events. The shear values for gypsum wallboard
contained in the code are based on mono-directional testing. It is
Page 15 of 41
appropriate to limit the use of this product until cyclic loading tests are
performed and evaluated.
7.32.250 Section 2308.9.3, Chapter 23, Bracing, Item 7-Amended.
Section 2320.11.3, Item 7 is amended to read:
Portland cement plaster on studs spaced 16 inches (406 mm) on center installed in
accordance with Section 2510. Limited to single story U occupancies.
FINDING: The amendment is needed due to local geological conditions.
This section limits the use of Portland cement plaster for lateral bracing to
single story residential buildings. This limitation is necessary because the
City of Dublin is located in Seismic Zone D and E. Exterior Portland cement
plaster has performed poorly during recent California seismic events. The
shear values for Portland cement stucco contained in the code are based on
mono-directional testing. It is appropriate to limit the use of this product
until cyclic loading tests are performed and evaluated.
7.32.260 Section 2308.12.5, Attachment of Sheathing-Amended.
Section 2308.12.5, is amended by adding a second paragraph:
All braced wall panels shall extend to the roof sheathing and shall be attached to parallel
roof rafters or blocking above with framing clips (18 gauge minimum) spaced at maximum
24 inches (6096 mm) on center with four 8d nails per leg (total eight 8d nails per clip).
Braced wall panels shall be laterally braced at each top corner and at maximum 24 inch
(6096 mm) intervals along the top plate of discontinuous vertical framing.
FINDINGS: The amendment is needed due to local geological, climatic and
topographical conditions.
The San Francisco Bay area region is densely populated and/or located in an
area of high seismic activities as indicated by United States Geological
Survey and California Division of Mines and Geology. Recent earthquake
activities, including the 1989 Loma Prieta earthquake, have indicated the
lack of adequate design and detailing as a contributing factor to damages

It shall be unlawful to install a wood burning fireplace or appliance that is not one of the
following:
1) Pellet-fueled wood heater,
2) EPA certified wood heater,
3) Fireplace certified by EPA
FINDING: The amendment is needed due to local climatic and topographical
conditions.
This modification was necessary because fireplaces and wood stoves
generate 40 percent of the particulate matter in the Bay Area during the
winter months. Of greater concern are the fine particles, which can lodge
deep in the lungs causing permanent lung damage and increasing mortality.
Burning wood also generates carbon monoxide, nitrogen dioxide, volatile
organic and toxic air pollutants.
7.32.280 Section 3203, Chapter 32, Signs-Added.
A new Section 3203 is added to read:
Section 3203 Signs. Signs when placed flat against the wall of a building shall not project
beyond the front property line more than 12 inches (305mm).
FINDING: The amendment is needed due to local climatic and topographical
conditions.
This modification was necessary due to the City of Dublin's basic wind
speed requirement relating to the high winds described in Section A of these
Findings.
7.32.290 Section H101.2, Signs exempt from permits -Deleted.
Section H101.2 is deleted.
FINDING: The amendment is needed due to local climatic and topographical
conditions.

FINDINGS: The amendment is needed due to local geological, climatic and
topographical conditions.
The San Francisco Bay Area region is densely populated and/or located in
an area of high seismic activities as indicated by United States Geological
Survey and California Division of Mines and Geology. Recent earthquake
activities, including the 1989 Loma Prieta earthquake, have indicated the
lack of adequate design and detailing as a contributing factor to damages
that reduced the protection of the life-safety of building occupants. The City
of Dublin is a densely populated area having buildings constructed near
potentially active faults. The Association of Bay Area Governments (ABAG)
roughly estimates the probability of a serious earthquake along the Hayward
Fault as one-in-four in the next 30 years, while the USGS predict the
probability of a powerful quake in the next 30 years at 62%. The proposed
modification to ensure that the design of slender wall must satisfy both
strength and serviceability requirements need to be incorporated into the
code to assure that new buildings and additions to existing buildings are
designed and constructed in accordance with the scope and objectives of
the International Building Code.

conforms to Class C or better or shall be made of concrete, ferrous or copper metal,
clay, slate or similar non-combustible material.
*Editor's Note: Figure 15-1 is on file in the office of the City Clerk.
FINDING: The amendment is needed due to local climatic and topographical
conditions.
This modification was necessary because the City of Dublin has a dry
period of at least five months each year. Additionally, The area is subject to
occasional drought. Because of dryness, a rapidly burning grass fire or
exterior building fire can quickly transfer to other buildings. These
modifications are consistent with the Fire Authority having jurisdiction.

7.34.210 Section R1001.1.2 Chapter 10, Prohibited Installations—Added.
A new Section R1001.1.2 is added to read:
It shall be unlawful to install a new wood burning fireplace or appliance that is not one of
the following:
1. Pellet-fueled wood heater,
2. EPA certified wood heater,
3. Fireplace certified by EPA
FINDING: The amendment is needed due to local climatic and topographical
conditions.
This modification was necessary because fireplaces and wood stoves
generate 40 percent of the particulate matter in the Bay Area during the
winter months. Of greater concern are the fine particles, which can lodge
deep in the lungs causing permanent lung damage and increasing mortality.
Burning wood also generates carbon monoxide, nitrogen dioxide, volatile
organic and toxic air pollutants.

Section 7.36.080 DMC Section 210-53, Office receptacle outlets-Added.
Section 210-53 is added to read:
Section 210-53 Office Receptacle Outlets. In office buildings or offices exceeding ten
(10) percent of the floor area of the major use, receptacle outlets shall be installed in all
permanent walls or partitions so that no point along the floor line any wall space is
more than six (6) feet (1.83m) measured horizontally, from an outlet in that space
including any wall space two (2) feet (610 mm) or more in width and the wall space
occupied by sliding panels in exterior walls.
As used in the section a "wall space" shall be considered a wall unbroken along the
floor line by doorways, fireplaces, and similar openings. Each wall space two (2) or
more feet (610 mm) wide shall be treated individually and separately from other wall
spaces within the room. A wall space shall be permitted to include two or more walls of
a room (around corners) where unbroken at the floor line.
Receptacle outlets shall, insofar as practicable be spaced equal distances apart.
Receptacle outlets in floors shall not be counted as part of the required number of
receptacle outlets unless located near the wall.
The receptacle outlets required by the section shall be in addition to any receptacle
that is part of any lighting fixture or appliance, located within cabinets or cupboards, or
located over five and one-half(5 1/2) feet (1.68 m) above the floor.
FINDINGS: The amendment is needed due to local geological conditions.
This section requires additional receptacles. The City of Dublin is located in
a highly active Seismic Zone D and E. In Office Buildings without these
requirements extension codes are being used. Extension cords are not
afforded the same protection from damage as wiring raceways. Damage to
Page 36 of 41
extension cords could occur in a seismic event, which increases the
potential for a fire.

Section 7.40.080 DMC Section 609.3, Chapter 6 UPC, Water piping in slab floors—
Amended.
Section 609.3, first paragraph, is amended by replacing it to read:
Section 609.3 Water piping shall not be installed in or under a concrete floor slab
within a building without prior approval of the Building Official. When approved,
such piping shall be installed in accordance with the following requirements:
FINDINGS The amendment is needed due to local geological conditions.
This section eliminates water piping in or under concrete floor slabs within a
building. This amendment is necessary for the following reasons:
(1) Most of the surface soils in the City of Dublin are relatively young and
unconsolidated sedimentary materials formed from a wide variety of parent
materials. The varying chemical composition, degree of weathering and the
relatively acid environment have created soils of varying types, which are
particularly corrosive in nature.
(2) Much of the surface soil in the City of Dublin is highly expansive (i.e., shrink-
swell behavior) and have low bearing strength.
(3) There are two types of expansive soils in the area:
a. the organic silty clays which are the recent bay muds; and
b. the plastic silty clays which weather from the shale found in the hills
surrounding the City of Dublin
(4) The local climate is characterized by markedly delineated rainy and dry
seasons, which tend to maximize the expansive characteristics of soil.
(5) Some parts of the City of Dublin have hard water, which is corrosive to
ferrous pipe.
(6) The groundwater table is unusually high in many places.
(7) The City of Dublin is a highly active seismic area.
6. California Mechanical Code
No modifications necessitating specific findings are adopted.

7.94.040 Scope.
Page 37 of 41
A. The provisions of this code shall apply to the planning, design, operation,
construction, use, and occupancy of every newly constructed building or structure,
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 twenty (20) residential units.
FINDINGS The amendment is needed due to local climatic, topographical and
environmental conditions.
Green building design, construction and operation can have a significant positive
effect on energy resource efficiency, waste and pollution generation, and the health
and productivity of building occupants over the life of the building. This modification
was necessary because the City of Dublin has a dry, hot period of at least five months
each year. As a result of the high 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"). Additionally, the area is subject to occasional drought.
Reduction of total and peak energy use and water use as a result of incremental
conservation measures required by this ordinance will have local benefits in the
additional available system energy and water capacity.

7.94.080 Standards for Compliance.
A. Covered projects shall achieve a minimum Green Building Program Rating of fifty (50) points
under the Green Building Program Checklist for single-family housing. All multi-family
residential projects shall achieve a "green home" or similarly entitled minimum compliance rating
system, which currently requires fifty (50) GreenPoints, or a minimum Green Building Program
Rating of fifty (50) points under the Green Building Program Checklist for multi-family housing,
unless the Building Official determines that the single-family green building rating system is
more appropriate for the building, such as for a duplex building that is part of a larger project.
Approval of a building permit for new construction shall not be granted unless the Applicant
submits a checklist demonstrating the covered project receives the minimum Green Building
Program Rating required on the appropriate Green Building Program Checklist.
All mixed-use projects shall meet the requirements for a multi-family residential project, unless
the Building Official determines the Green Building Code or another rating system is more
appropriate.
Page 40 of 41
B. In the event that an Applicant wishes to use an alternative green building standards program
other than the GreenPoint rating system or the LEEDtm for Homes Green Building Rating
System, the Applicant may apply to the Building Official for approval of the alternative program.
The Applicant must submit Green Building Documentation showing that the Applicant's
utilization of the alternative program will result in green building benefits that are better than the
benefits that would be achieved by obtaining a Green Building Program Rating of fifty (50)
points under either the GreenPoint rating system or the LEEDtm for Homes Green Building
Rating System.
Any proposed alternative green building program must be created by a third-party entity not
under the control of the Applicant, and must be sufficiently similar in structure to the GreenPoint
rating system and the LEEDtm for Homes Green Building Rating System to allow the Building
Official to administer the requirements of this Chapter to the alternative green building standards
program without significant deviation. At a minimum, the alternative green building standards
program must utilize a checklist structure similar to the Green Building Program Checklists.
No Applicant may utilize an alternative green building standards program unless the Building
Official gives the Applicant written approval of the Applicant's proposed utilization of the
program.
