Recommendation
City of Palo Alto Page 2
Staff recommends that the City Council conduct a public hearing and then adopt the attached
eight ordinances adopting, by reference, the various parts of the 2013 California Building
Standards Code (CBSC), Title 24 of the California Code of Regulations (described further in the
“Background” section of this report). Seven of the ordinances also contain proposed local
amendments to the State model codes, along with the necessary findings of fact supporting
each local amendment.
Executive Summary
Every three years, the State of California adopts new building standards that are codified in
Title 24 of the California Code of Regulations, referred to as the California Building Standards
Code. Upon publication of the new Building Standards Code, local jurisdictions are allowed 180
days within which to amend the model State codes to enact more stringent local building
standards. Such local amendments to the model State codes must be supported with findings
that are based on unique local climatic, geologic and topographic conditions. To adopt the
model State codes and local amendments, a public hearing must be held after which the
various ordinances containing the proposed local amendments and findings for each part of the
Building Standards Code can be passed. This report explains the process for adoption of the
2013 California Building Standards Code that will become effective statewide on January 1,
2014 and summarizes the proposed local amendments.
Background
The eight ordinances are described below:
1. Ordinance repealing Chapter 16.04 of the Palo Alto Municipal Code and amending Title
16 to adopt a new Chapter 16.04, California Building Code, California Historical Building
Code, and California Existing Building Code, 2013 Editions, and Local Amendments and
Related Findings – The California Building Code (CBC) is the fundamental building code
within the State of California that regulates most new building construction and is based on
the 2012 International Building Code (IBC), written by the International Code Council (ICC),
as amended by the California Building Standards Commission. The 2013 California Historical
Building Code (CHBC) is unique to California and prescribes building standards for
designated historic structures aimed at balancing the goals of historic preservation with life,
safety and accessibility concerns when the provisions of the regular building code cannot be
achieved. The 2013 California Existing Building Code (CEBC) is based on the 2012
International Existing Building Code, also written by the ICC, as amended by the Building
Standards Commission. Similar to the CHBC, the CEBC prescribes alternative building
standards for repairs to existing structures when the provisions of the regular code cannot
be achieved.

2. Ordinance repealing Chapter 16.05 of the Palo Alto Municipal Code and amending Title
16 to adopt a new Chapter 16.05, California Mechanical Code, 2013 Edition, and Local
Amendments and Related Findings – The California Mechanical Code (CMC) is based on the
2012 Uniform Mechanical Code (UMC), written by the International Association of Plumbing
& Mechanical Officials (IAPMO), as amended by the Building Standards Commission, and
prescribes standards for mechanical heating, ventilating and cooling systems, and
appurtenant equipment, within buildings.
3. Ordinance repealing Chapter 16.06 of the Palo Alto Municipal Code and amending Title 16
to adopt a new Chapter 16.06, California Residential Code, 2013 Edition, and Local
Amendments and Related Findings – The California Residential Code (CRC) is based on the
2012 International Residential Code (IRC) which is written by the International Code
Council, as amended by the Building Standards Commission. The Residential Code is a
simplified version of the Building Code and prescribes building standards for low-rise (one
and two-story), single and two-family dwelling units.
4. Ordinance repealing Chapter 16.08 of the Palo Alto Municipal Code and amending Title 16
to adopt a new Chapter 16.08, California Plumbing Code, 2013 Edition, and Local
Amendments and Related Findings – The California Plumbing Code (CPC) is based on the
2012 Uniform Plumbing Code (UPC), also written by the IAPMO, as amended by the Building
Standards Commission, and prescribes standards for water and wastewater distribution
systems, and appurtenant equipment, within buildings.
5. Ordinance repealing Chapter 16.14 of the Palo Alto Municipal Code and amending Title 16
to adopt a new Chapter 16.14, California Green Building Standard Code, 2013 Edition, and
Local Amendments and Related Findings – The California Green Building Standard Code
(Cal Green) is unique to California. It is not based upon a model code nor adopted by
reference. The purpose of Cal Green is to improve public health, safety and general welfare
through enhancement of design and construction of buildings using building concepts
reducing negative impacts or having positive environmental impacts and encouraging
sustainable construction practices. As such, Cal Green along with City of Palo Alto
amendments, applies to planning, design, operation, construction, use and occupancy of
residential and non-residential construction.
6. Ordinance repealing Chapter 16.16 of the Palo Alto Municipal Code and amending Title 16
to adopt a new Chapter 16.16, California Electrical Code, 2013 Edition– The 2013 California
Electrical Code (CEC) is based on the 2011 National Electrical Code, written by the National
Fire Protection Agency (NFPA), as amended by the Building Standards Commission, and
prescribes standards for electrical supply and operating systems and appurtenant
equipment within buildings.
7. Ordinance repealing Chapter 16.17 of the Palo Alto Municipal Code and amending Title 16
to adopt a new Chapter 16.17, California Energy Code, 2013 Edition– The 2013 California
Energy Code is unique to California. It is not based upon a model code nor adopted by
reference. The California Energy Commission (CEC) is the state’s primary energy policy and
planning agency. As such, the CEC adopts regulations to establish the minimum level of
City of Palo Alto Page 4
energy efficiency a heated or cooled structure must meet or exceed. The 2013 code will
continue to improve upon the current 2008 Standards for new construction of, and
additions and alterations to, residential and nonresidential buildings. These Standards will
help save Palo Alto residents money on their utility bills, keep them comfortable in their
homes, and reduce greenhouse gas emissions through better, more efficient buildings.
8. Ordinance repealing Chapter 15.04 of the Palo Alto Municipal Code and amending Title 15
to Adopt a new Chapter 15.04, California Fire Code, 2013 Edition – The 2013 California Fire
Code is based on the 2012 International Fire Code. The 2013 code improves upon the 2010
Standards for reducing hazards, increasing fire life safety, and property preservation. Most
local amendments are derived from the collaborative efforts of the County Fire Marshal’s
Association.
Discussion
Typically, a new edition of the CBSC is published and adopted by the State of California every
three years, based substantially on the model uniform codes. Palo Alto last adopted new
building codes in 2010. This year, the Building Standards Commission adopted and published a
new edition of the CBSC based on the 2012 IBC and updated versions of other model codes.
The new CBSC will become effective statewide on January 1, 2014, as published, unless local
jurisdictions adopt more stringent amendments in accordance with State law. Generally, the
local amendment process requires local authorities to make specific findings to support each
local amendment, based on climatic, geologic or topographic conditions that are unique to each
jurisdiction. For Palo Alto’s proposed local amendments, these findings of fact are attached to
each Ordinance where applicable.
Many of the proposed local amendments to the 2013 California Building and Residential Codes
are administrative in nature and are intended to maintain consistency with other provisions of
the Municipal Code and reflect the City’s current policies and practices dealing with building
code enforcement. The proposed local amendments that are technical in nature have been
developed in concert with building officials, fire chiefs and code consultants from throughout
the region to promote consistency across jurisdictions. A number of these amendments
address aspects of the CBC or IRC that would otherwise allow less restrictive building design
and construction practices than what currently exists, particularly with respect to structural
analysis and seismic safety. Additionally, new repair and reconstruction standards are
proposed for incorporation into the Building Code to meet the Federal Emergency
Management Association’s (FEMA’s) eligibility requirements for post-disaster funding
assistance for repairs to public and private non-profit-owned buildings damaged in disasters.
Other amendments to both the Building and Residential Codes ensure consistency with
provisions of the 2013 California Fire Code that is being adopted concurrent with these codes.
City of Palo Alto Page 5
A few local amendments are proposed to the 2013 California Electrical and Mechanical Codes
that take into account climatic and geological uniqueness of Palo Alto while several are
proposed to the Plumbing Code. These Plumbing Code amendments are intended to promote
consistency with Palo Alto’s Sewer Use Ordinance (PAMC Chapter 16.09) and support the City’s
efforts to reduce copper and other heavy metal discharges from the Wastewater Treatment
Plant, in addition to water conservation, (e.g. the prohibition of single-pass cooling systems).
The development of the Cal Green Code is intended to, cause a reduction in greenhouse gas
emissions from buildings; (2) promote environmentally responsible, cost-effective, healthier
places to live and work; and (3) reduce energy and water consumption.
Local amendments to the 2013 California Fire Code are recommended primarily in the areas of
provision of site maps for fire permit final, clarifications relating to smoke detectors and fire
sprinklers and regulations pertaining to holiday haunted houses.
According to the Building Standards Commission, adoption of the new state model codes will
also increase the insurance industry’s Building Code Effectiveness Grading for California
communities, which insurance companies can then use to grant premium credits for buildings
constructed and enforced under the latest codes. These ratings were downgraded in prior
years because California had not adopted the latest model codes.
Conclusion
Consistent with State law, the California Codes will go into effect in Palo Alto on January 1,
2014, unless amended by local ordinance adopted prior to January 1. Thus, Palo Alto’s local
amendments will be effective on January 1, 2014, when the model codes will otherwise go into
effect statewide. Prior to the effective date, Building Division staff will undergo comprehensive
training on the new codes and an outreach and public education effort aimed at the design and
construction sectors that regularly work in Palo Alto will be implemented.
Resource Impact
Resource impacts from the adoption of these ordinances are limited to staff training costs,
purchasing copies of the new codes and implementation of public outreach efforts.
Policy Implications
The State of California mandates enforcement of the updated California Building Standards
Code and it will go into effect regardless of the City’s action or lack of action. The City does
have discretion to adopt local amendments to the CBSC, which must be effective by January 1,
2014.

Exhibit A
FINDINGS FOR LOCAL AMENDMENTS
TO CALIFORNIA BUILDING CODE
Section 17958 of the California Health and Safety Code provides that the City may make
changes to the provisions of the California Building Standards Code. Sections 17958.5 and
17958.7 of the Health and Safety Code require that for each proposed local change to those
provisions of the California Building Standards Code which regulate buildings used for human
habitation, the City Council must make findings supporting its determination that each such
local change is reasonably necessary because of local climatic, geological, or topographical
conditions.
Local building regulations having the effect of amending the uniform codes, which were
adopted by the City prior to November 23, 1970, were unaffected by the regulations of Sections
17958, 17958.5 and 17958.7 of the Health and Safety Code. Therefore, amendments to the
uniform codes which were adopted by the City Council prior to November 23, 1970, and have
been carried through from year to year without significant change, need no required findings.
Also, amendments to provisions not regulating buildings used for human habitation do not
require findings.

Key to Justification for Amendments to Title 24 of the California Code of Regulations
This amendment is justified on the basis of a local climatic condition. The seasonal climatic
conditions during the late summer and fall create severe fire hazards to the public health and
welfare in the City. The hot, dry weather frequently results in wild land fires on the brush
covered slopes west of Interstate 280. The aforementioned conditions combined with the
geological characteristics of the hills within the City create hazardous conditions for which
departure from California Building Standards Code is required.
C
G
T
This amendment is justified on the basis of a local geological condition. The City of Palo
Alto is subject to earthquake hazard caused by its proximity to San Andreas fault. This
fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma
Prieta earthquake, then on up the San Francisco Peninsula, then offshore at Daly City near
Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco
earthquake. The other fault is Hayward Fault. This fault is about 74 mi long, situated
mainly along the western base of the hills on the east side of San Francisco Bay. Both of
these faults are considered major Northern California earthquake faults which may
experience rupture at any time. Thus, because the City is within a seismic area which
includes these earthquake faults, the modifications and changes cited herein are designed
to better limit property damage as a result of seismic activity and to establish criteria for
repair of damaged properties following a local emergency.
The City of Palo Alto topography includes hillsides with narrow and winding access, which
makes timely response by fire suppression vehicles difficult. Palo Alto is contiguous with the
San Francisco Bay, resulting in a natural receptor for storm and waste water run-off. Also the
City of Palo Alto is located in an area that is potentially susceptible to liquefaction during a
major earthquake. The surface condition consists mostly of stiff to dense sandy clay, which is
highly plastic and expansive in nature. The aforementioned conditions within the City create
hazardous conditions for which departure from California Building Standards Code is
warranted.

BUILD IT GREEN, GREENPOINT RATED. Build It Green is a non-profit organization that
administers the Green Point Rated program for the design and construction of
environmentally responsive and healthy homes. The program includes a rating system
that is third-party verified and includes recognition.
DEDICATED IRRIGATION METER. A dedicated irrigation meter is a water meter that
exclusively meters water used for outdoor watering and irrigation, and is completely
independent from the meter used for indoor water use.
HERS II. HERS shall mean the California Home Energy Rating System, a statewide
program for residential dwellings administered by the California Energy Commission and
defined in the 2008 California Building Energy Efficiency Standards. HERS Phase I
provides field verification and diagnostic testing to show compliance with Title 24, Part
6, of the 2008 California Building Energy Efficiency Standards. HERS Phase II includes
whole-house home energy efficiency ratings for existing and newly constructed homes.
Applicants are not required to achieve a set rating.

and may be prohibited by this code are defined as such in the “Water Use Classification
of Landscape Species (WUCOLS), A Guide to the Water Needs of Landscape Plants,”
from the University of California Cooperative Extension.
MODEL WATER EFFICIENT LANDSCAPE ORDINANCE. The California ordinance regulating
new construction and rehabilitated landscape project design, installation and
maintenance. The Model Ordinance assigns a Maximum Applied Water Allowance
(MAWA) based on landscaped area and climatological parameters. The City of Palo Alto
has adopted more stringent compliance regulations in this code than the Model
Ordinance; however, the Model Ordinance is referenced as the guiding document for
water use calculations, irrigation system design, and water waste prevention.
PROCESS WATER. Process water means untreated wastewater, uncontaminated by
toilet discharge or an unhealthy bodily waste, which is not a threat from unhealthful
processing, manufacturing or operating wastes.
SALVAGE. Salvage means the controlled removal of construction or demolition debris/
material from a building, construction, or demolition site for the purpose of on- or off-
site reuse, or storage for later reuse. Examples include air conditioning and heating
systems, columns, balustrades, fountains, gazebos, molding, mantels, pavers, planters,
quoins, stair treads, trim, wall caps, bath tubs, bricks, cabinetry, carpet, doors, ceiling

Exhibit A
FINDINGS FOR LOCAL AMENDMENTS TO
CALIFORNIA GREEN BUILDING STANDARD CODE, 2010 EDITION
Section 17958 of the California Health and Safety Code provides that the City may
make changes to the provisions in the uniform codes that are published in the California
Building Standards Code. Sections 17958.5 and 17958.7 of the Health and Safety Code require
that for each proposed local change to those provisions in the uniform codes and published in
the California Building Standards Code which regulate buildings used for human habitation, the
City Council must make findings supporting its determination that each such local change is
reasonably necessary because of local climatic, geological, or topographical conditions.
Local building regulations having the effect of amending the uniform codes, which
were adopted by the City prior to November 23, 1970, were unaffected by the regulations of
Sections 17958, 17958.5 and 17958.7 of the Health and Safety Code. Therefore, amendments
to the uniform codes which were adopted by the City Council prior to November 23, 1970, and
have been carried through from year to year without significant change, need no required
findings. Also, amendments to provisions not regulating buildings used for human habitation,
including amendments made only for administrative consistency, do not require findings.

Key to Justification for Amendments to Title 24 of the California Code
of Regulations
C
This amendment is justified on the basis of a local climatic condition. The seasonal climatic
conditions during the late summer and fall create severe fire hazards to the public health and
welfare in the City. The hot, dry weather frequently results in wild land fires on the brush
covered slopes west of Interstate 280. The aforementioned conditions combined with the
geological characteristics of the hills within the City create hazardous conditions for which
departure from California Building Standards Code is required.
Failure to address and significantly reduce greenhouse gas (GHG) emissions could result in
rises in sea level, including in San Francisco Bay, that could put at risk Palo Alto homes and
businesses, public facilities, and Highway 101 (Bayshore Freeway), particularly the mapped
Flood Hazard areas of the City. Energy efficiency is a key component in reducing GHG
emissions, and construction of more energy efficient buildings can help Palo Alto reduce its
share of the GHG emissions that contribute to climate change. The burning of fossil fuels
used in the generation of electric power and heating of buildings contributes to climate
change, which could result in rises in sea level, including in San Francisco Bay, that could put
at risk Palo Alto homes and businesses 1 public facilities, and Highway 101. Due to decrease
in annual rain fall, Palo Alto experiences the effect of drought and water saving more than
some other communities in California.
E Green building enhances the public health and welfare by promoting the environmental and
economic health of the City through the design, construction, maintenance, operation and
deconstruction of buildings and sites by incorporating green practices into all development.
The green provisions in this Chapter are designed to achieve the following goals:
(a) Increase energy efficiency in buildings;
(b) Increase water and resource conservation;
(c) Reduce waste generated by construction and demolition projects;
(d) Provide durable buildings that are efficient and economical to own and operate;
( e) Promote the health and productivity of residents, workers, and visitors to the city;
(f) Recognize and conserve the energy embodied in existing buildings;
(g) Encourage alternative transportation; and
(h) Reduce disturbance of natural ecosystems.
G
T
This amendment is justified on the basis of a local geological condition. The City of Palo
Alto is subject to earthquake hazard caused by its proximity to San Andreas fault. This
fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma
Prieta earthquake, then on up the San Francisco Peninsula, then offshore at Daly City near
Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco
earthquake. The other fault is Hayward Fault. This fault is about 74 mi long, situated
mainly along the western base of the hills on the east side of San Francisco Bay. Both of
these faults are considered major Northern California earthquake faults which may
experience rupture at any time. Thus, because the City is within a seismic area which
includes these earthquake faults, the modifications and changes cited herein are designed
to better limit property damage as a result of seismic activity and to establish criteria for
repair of damaged properties following a local emergency.
The City of Palo Alto topography includes hillsides with narrow and winding access, which
makes timely response by fire suppression vehicles difficult. Palo Alto is contiguous with the
San Francisco Bay, resulting in a natural receptor for storm and waste water run-off. Also the

City of Palo Alto is located in an area that is potentially susceptible to liquefaction during a
major earthquake. The surface condition consists mostly of stiff to dense sandy clay, which is
highly plastic and expansive in nature. The aforementioned conditions within the City create
hazardous conditions for which departure from California Building Standards Code is
warranted.

Exhibit A
FINDINGS FOR LOCAL AMENDMENTS TO
CALIFORNIA PLUMBING CODE, 2010 EDITION
Section 17958 of the California Health and Safety Code provides that the City may
make changes to the provisions in the uniform codes that are published in the California
Building Standards Code. Sections 17958.5 and 17958.7 of the Health and Safety Code require
that for each proposed local change to those provisions in the uniform codes and published in
the California Building Standards Code which regulate buildings used for human habitation, the
City Council must make findings supporting its determination that each such local change is
reasonably necessary because of local climatic, geological, or topographical conditions.
Local building regulations having the effect of amending the uniform codes, which
were adopted by the City prior to November 23, 1970, were unaffected by the regulations of
Sections 17958, 17958.5 and 17958.7 of the Health and Safety Code. Therefore, amendments
to the uniform codes which were adopted by the City Council prior to November 23, 1970, and
have been carried through from year to year without significant change, need no required
findings. Also, amendments to provisions not regulating buildings used for human habitation,
including amendments made only for administrative consistency, do not require findings.

Key to Justification for Amendments to Title 24 of the California Code of Regulations
This amendment is justified on the basis of a local climatic condition. The seasonal
climatic conditions during the late summer and fall create severe fire hazards to the
public health and welfare in the City. The hot, dry weather frequently results in wild
land fires on the brush covered slopes west of Interstate 280. The aforementioned
conditions combined with the geological characteristics of the hills within the City
create hazardous conditions for which departure from California Building Standards
Code is required.
C
G
T
This amendment is justified on the basis of a local geological condition. The City of
Palo Alto is subject to earthquake hazard caused by its proximity to San Andreas
fault. This fault runs from Hollister, through the Santa Cruz Mountains, epicenter
of the 1989 Loma Prieta earthquake, then on up the San Francisco Peninsula, then
offshore at Daly City near Mussel Rock. This is the approximate location of the
epicenter of the 1906 San Francisco earthquake. The other fault is Hayward Fault.
This fault is about 74 mi long, situated mainly along the western base of the hills
on the east side of San Francisco Bay. Both of these faults are considered major
Northern California earthquake faults which may experience rupture at any time.
Thus, because the City is within a seismic area which includes these earthquake
faults, the modifications and changes cited herein are designed to better limit
property damage as a result of seismic activity and to establish criteria for repair
of damaged properties following a local emergency.
The City of Palo Alto topography includes hillsides with narrow and winding access,
which makes timely response by fire suppression vehicles difficult. Palo Alto is
contiguous with the San Francisco Bay, resulting in a natural receptor for storm and
waste water run-off. Also the City of Palo Alto is located in an area that is potentially
susceptible to liquefaction during a major earthquake. The surface condition consists
mostly of stiff to dense sandy clay, which is highly plastic and expansive in nature. The
aforementioned conditions within the City create hazardous conditions for which
departure from California Building Standards Code is warranted.

Key to Justification for Amendments to Title 24 of the California Code of Regulations
This amendment is justified on the basis of a local climatic condition. The seasonal climatic
conditions during the late summer and fall create severe fire hazards to the public health and
welfare in the City. The hot, dry weather frequently results in wild land fires on the brush
covered slopes west of Interstate 280. The aforementioned conditions combined with the
geological characteristics of the hills within the City create hazardous conditions for which
departure from California Building Standards Code is required.
C
G
T
This amendment is justified on the basis of a local geological condition. The City of Palo
Alto is subject to earthquake hazard caused by its proximity to San Andreas fault. This
fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma
Prieta earthquake, then on up the San Francisco Peninsula, then offshore at Daly City near
Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco
earthquake. The other fault is Hayward Fault. This fault is about 74 mi long, situated
mainly along the western base of the hills on the east side of San Francisco Bay. Both of
these faults are considered major Northern California earthquake faults which may
experience rupture at any time. Thus, because the City is within a seismic area which
includes these earthquake faults, the modifications and changes cited herein are designed
to better limit property damage as a result of seismic activity and to establish criteria for
repair of damaged properties following a local emergency.
The City of Palo Alto topography includes hillsides with narrow and winding access, which
makes timely response by fire suppression vehicles difficult. Palo Alto is contiguous with the
San Francisco Bay, resulting in a natural receptor for storm and waste water run-off. Also the
City of Palo Alto is located in an area that is potentially susceptible to liquefaction during a
major earthquake. The surface condition consists mostly of stiff to dense sandy clay, which is
highly plastic and expansive in nature. The aforementioned conditions within the City create
hazardous conditions for which departure from California Building Standards Code is
warranted.

1901.1 Purpose. The purpose of this appendix is to provide a reasonable degree
of safety to persons occupying existing high-rise buildings by requiring
minimum standards for exit corridors, exit stairways and elevator shafts,
monitored alarm systems and emergency plans.
1901.2 Scope. The requirements shall apply to all high-rise buildings
constructed prior to January 1, 1994 which have floors used for human
occupancy located more than 75 feet above the lowest level of approved fire
department vehicle access or other physical configuration that qualifies a
building as high rise by local ordinance.
1901.3 Permits Required.
1. Building permits shall be obtained as required by the Building Code.
2. Not less than 30 days prior to submitting plans for a building permit, a
preplan review meeting shall be held, including the owner’s design team,
building official and the chief, to determine the adequacy of the life-safety
emergency systems concept for the building. The life-safety emergency systems
shall be reflected on the plans for the building and become a permanent part
of the building department’s records. The building official and the chief may
require sufficient documentation, based upon engineering analysis, that the
concept meets the intent of nationally recognized good practices and such
guidelines as the building official and chief have published.
1901.4 Enforcement. The provisions of this appendix shall be enforced by the
chief.
1901.5 Compliance. All buildings shall be made to conform with the
requirements of Section 1902 within the following time periods:

EXHIBIT A
Findings for Local Amendments to the
2013 California Fire Code
The following local amendments to the 2013 California Fire Code make modifications as authorized
by the California Health and Safety Code. In accordance with Section 18941.5 of said Code,
Findings are hereby made to show that such modifications or changes are reasonably
necessary because of local climatic, geological or topographical conditions.
PREAMBLE I.
Findings of fact:
A. Pursuant to Section 17958.5 of the California Health and Safety Code, the report
contained herein is submitted as the “Findings of Fact” document with regard to the adoption of
the California Fire Code, 2013 Edition, and amendments. Under this adopting ordinance,
specific amendments have been established which are more restrictive in nature than those
adopted by the State of California (State Building Code Standards, State Housing and
Community Development Codes) commonly referred to as California Code of Regulations, Titles
19, 24 and 25.
B. These amendments to the California Fire Code, 2013 Edition, have been recognized by the
City of Palo Alto (“City”) as tools for addressing the fire problems, concerns and future direction
by which the authority can establish and maintain an environment which will afford a level of
fire and life safety to all who live and work within the City’s boundaries.
C. Under the provisions of Section 17958.5 of the Health and Safety Code, local amendments
shall be based upon the following: climatic, geological/geographical, and topographical conditions.
The findings of fact contained herein shall address each of these situations and shall present the
local situation which, either singularly or in combination, caused the established amendments
to be adopted.
1. Climactic Conditions:
The City, on an average, experiences an annual rainfall of 16" - 18". This rainfall can be expected
between October and April of each year. However, during the summer months there is little, if
any, measurable precipitation. During this dry period the temperatures are usually between
70-90 degrees with light to gusty westerly winds. These drying winds, combined with the
natural vegetation which is dominant throughout the area, create a hazardous fuel condition
which can cause, and has caused in the past, extensive grass and brush land fires. With more
and more development encroaching into these wooded and grass covered areas, wind-driven
fires could have severe consequences, as has been demonstrated on several occasions in Palo Alto
and other areas of the state. Fires in structures can easily spread to the wildland as well as a fire in
the wildland into a structure.
57

131015 jb 0131145-A 57
Because of the weather patterns, a normal rainfall cannot always be relied upon. This can result
in water rationing and water allocation systems, as demonstrated by the drought years of 1986-
1991. Water shortages can also be expected in the future due to the current water storage
capacities and increased consumption. The water supply for the Palo Alto fire department makes
use of automatic fire sprinkler systems feasible as a means to reduce our dependency on large
volumes of water for fire suppression.
2. Geological & Geographical Conditions
Geographical Location. Palo Alto is located at the northern most part of Santa Clara County. Palo
Alto is a major focus of the “Silicon Valley,” the center for an expanding and changing electronics
industry, as well as pharmaceutical, biomedical, and genetic research.
Seismic Location. Palo Alto is situated on alluvial solids between San Francisco Bay and the San
Andreas Fault zone. The City’s location makes it particularly vulnerable to damage to taller and
older structures caused by seismic events. The relatively young geological processes that
have created the San Francisco Bay Area are still active today. Seismically, the city sits
between two active earthquake faults (San Andreas and the Hayward/Calaveras), and numerous
potentially active faults. Approximately 55% of the City’s land surface is in the high-to-
moderate seismic hazard zones.
Seismic and Fire Hazards. Fire following an earthquake has the potential of causing greater loss of
life and damage than the earthquake itself.
The majority of the City’s high-rise structures are located in seismic risk zones. Should a significant
seismic event occur, Public Safety resources would have to be prioritized to mitigate the
greatest threat, and may not be available for every structural fire. In such event, individual
structures, including high-rise buildings, should be equipped to help in mitigating the risk of
damage.
Other variables may tend to intensify the situation:
a. The extent of damage to the water system;
b. The extent of isolation due to bridge and/or freeway overpass collapse;
c. The extent of roadway damage and/or amount of debris blocking the roadways;
d. Climatical conditions (hot, dry weather with high winds);
e. Time of day will influence the amount of traffic on roadways and could intensify the risk to
life during normal business hours;
f. The availability of timely mutual aid or military assistance;
g. Many high-rise structures are located near areas of high fire danger necessitating special
58

131015 jb 0131145-A 58
precautions.
Transportation. Palo Alto is dissected by a major state highway (El Camino Real) and two major
freeways (I-280 and U.S. 101), which potentially could negatively affect response times of fire
suppression equipment.
Soil Conditions. Palo Alto lies at the southern end of San Francisco Bay and is built atop the
alluvial deposits that surround the margins of the Bay. The alluvium was created by the flooding of
many streams emptying into the San Francisco Bay depression, and from intermittent sea
water inundation that has occurred over the last 2 or 3 million years. The areas closest to the
Bay are overlain by unconsolidated fine silty clay, known as Bay Mud which varies in thickness
from a few feet to as much as 30 feet. Generally, the older more stable alluvium is to the south
and the younger less stable material is to the north. Bedrock lies beneath the area at depths of
generally 300' or more.
3. Topographical Conditions:
The findings of fact for the topographical element, as would be expected, are closely associated
with the geological/geographical element. With the elevation changes within the district,
development is of course following the path of least resistance, creating a meandering pattern.
This then does not lend itself to a good systematic street and road layout, which would promote
easy traffic flow. It has, in fact, resulted in few major crosstown thoroughfares which tend to
be heavily congested, primarily during commute hours and seasonal periods of the year. This
creates barriers which reduce the response time of fire equipment and other emergency
services. The topography of the district is being burdened by major structures. Employment
areas are throughout the district. The people who work in these complexes have added to the
traffic congestion throughout the city, thereby reducing the fire department’s response time
capabilities.
Inherent delays caused by the traffic patterns to many of these types of projects, make it necessary
to mitigate this problem by requiring additional built-in automatic fire protection systems to
provide early detection and initial control until the arrival of the fire department.
The topography of the district in much of the commercial and residential zones lies within or near
a flood plane. Periodically, heavy rains and high tides cause region-wide flooding which not
only delays response but also increases demands on fire personnel. The fire code amendments
increase safeguards and initialize early response to help compensate for these physical delays.
As a result of the findings of facts which identify the various climatic, geological/geographical and
topographical elements, those additional requirements as specified in the amendments to
adopting ordinance for the California Fire Code 2013 Edition, by the City of Palo Alto area are
considered reasonable and necessary modifications. The experience of several disastrous fires
within the city in addition to Santa Clara, Monterey, San Mateo, Alameda and Contra
Costa counties have demonstrated the need for other fire protection features, the most
significant of which was located in the Oakland/Berkeley Hills in which over 3,000 homes were
destroyed and 25 human lives were lost. While it is clearly understood that the adoption of
59

131015 jb 0131145-A 59
such regulations may not prevent the incidence of fire, the implementation of these various
amendments to the Code may reduce the severity and potential of loss of life and property.
II. Specific Findings for Local Amendments
The majority of local amendments (those not specifically listed below) are made strictly to
conform to other parts of the Palo Alto Municipal Code (PAMC) and for similar administrative
purposes.
Based upon the findings of fact described in section I, the City Council also makes the following
specific findings regarding local climatic, geological, and topographic conditions related to local
amendments to the California and International Fire Codes found in Chapters 15.04 and 15.05
of Title 15 of the Palo Alto Municipal Code (“PAMC”):
1. The local amendments contained in PAMC sections 15.04.030 through 15.04.070 and
sections 15.04.325 through 15.04.441 relating to general conditions for hazardous materials
are necessary modifications to the California Fire Code flammable and hazardous materials
sections because they maintain consistency with the Hazardous Materials Storage Ordinance
which has been adopted county-wide since 1983. Requirements include safeguards such as
monitoring, secondary containment, separation of non compatibles which prevent incidents
should a seismic event, unauthorized release or accident occur.
2. The local amendment contained in PAMC section 15.05.015- Weed removal- is
necessary to require weeds to be removed from properties when determined to be a hazard at
the expense of the responsible party. Weeds can be a fire hazard that may also contribute to
the uncontrolled spread of fire as a result of the climatic, geographical, and topographical
conditions described in Findings 1, 2, and 3 above.
3. The local amendments contained in PAMC section 15.05.140 through 15.05.170 set forth
measures to limit delays in response time and reduce hazards to firefighters. These measures
are necessary to prevent exacerbation of response delays associated with the Climatic,
Geographical and Topographical conditions listed in Findings 1, 2 and 3 above.
4. The local amendment contained in PAMC section 15.04.210- Immersion Heaters- is
necessary as a fire control measure because it requires additional controls on process
heating devices which are often activated when unattended. See Geological Findings 2.
5. The local amendments contained in PAMC 15.04.230 through 15.04.260 relating to fire
sprinkler systems are necessary for faster control of fires in the dense populated area of our
community to confine a fire to the area of origin rather than spread to neighboring structures.
The modifications contained in these amendments provide additional fire extinguishing
systems in new construction, major remodels, additions, and occupancy classification changes
to help mitigate the problems identified in Findings 1, 2, and 3, above- Climatic, Geographical
and Topographical.
60
NOT YET APPROVED
131015 jb 0131145-A 60
6. The local amendment contained in PAMC section 15.04.270 - Floor control valves- is
necessary to provide fire extinguishing control devices that allow systems to remain partially in
service while repairs or maintenance are ongoing. See Findings 1 and 2 above- Climatic and
Geographical.
7. The local amendment contained in Section 15.04.275- Single- and multiple-station smoke
alarms- is necessary to alert occupants at the earliest possible stage of smoldering residential
fires.
This modification requires smoke detection provided in new construction, remodels, additions,
rental housing and newly purchased homes to be photoelectric or dual sensor technology to
allow greater likelihood of occupants safely escaping residential fires and notifying the fire
department during the earliest possible stage of fire growth. This will help mitigate the problems
identified in Findings 1, 2, and 3, above- Climatic, Geographical and Topographical.
8. The local amendments contained in PAMC sections 15.04.280 through 15.04.295 provide
for additional fire and life safety measures during construction and demolition. See Findings 2
and 3, above- Geographical and Topographical.
9. The local amendments contained in PAMC 15.04.300– Definition of “continuous gas
detection system” and sections 15.04.325, 15.04.352 and 15.04.450 through 15.04.502 regarding
toxic gases incorporate requirements established by the Model Toxic Gas Ordinance and
California Fire Code. Administrative and restrictive measures include changes in definitions,
quantities regulated, and utilizes County consensus guidelines established by other regional
agencies which share similar climatic, geological/geographical, and topographical conditions.
See Findings 1, 2 and 3, above- Climatic, Geographical and Topographical.
10. The local amendment contained in PAMC sections 15.04.310 and 15.04.320- Fire
Protection Water Supply System, requires an adequate water supply in areas used for storage of
highly combustible organic waste materials. This requirement mitigates the added hazards and
limited access conditions described in Findings 1 and 3, above- Climatic and Topographical.
11. The local amendments contained in PAMC section 15.04.510 - Storage and use of
liquefied petroleum gas- place restrictions on liquid petroleum gas where natural gas is
provided. These restrictions are appropriate given Palo Alto’s seismically active local geological
conditions because they will reduce portable container releases in the event of seismic
activity and mitigate the geological risk described in Finding 2, above- Geographical.
12. The local amendments contained in PAMC section 15.04.515 – Silane distribution systems
automatic shutdown- place restrictions on silane distribution systems. These restrictions are
appropriate given Palo Alto’s seismically active local geological conditions because they will
reduce release volume in the event of seismic activity or unauthorized release and mitigate the
geological risk described in Finding 2, above- Geographical.
13. The local amendments contained in PAMC sections 15.04.520 through 15.04.588 set
forth protections for urban-wildland interface areas that are necessary to mitigate the
additional fire risks in the Palo Alto foothills hazardous fire zone. The modifications contained
61
NOT YET APPROVED
131015 jb 0131145-A 61
in these amendments provide for additional precautions against fire risks and additional fire
extinguishing systems necessitated by the conditions listed in Findings 1, 2, and 3, above-
Climatic, Geographical and Topographical.
14. The local amendments contained in PAMC section 15.04.590- Life safety requirements
for existing high rise buildings- are designed to provide additional fire and life safety features in
existing high-rise buildings given the seismically sensitive geological conditions described in
Findings 2 and 3, above- Geographical and Topographical.
15. The local amendments contained in PAMC section 15.05.035- Roofguards at interior
courts provides for additional fire and life safety measures for firefighters on buildings with
unconventional lightwells. See Findings 2 and 3, above- Geographical and Topographical.
