Findings
The following local amendments to the 2001 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.
The majority of local amendments are made strictly to conform to
other parts of the Palo Alto Municipal Code (PAMC) or for similar
administrative purposes.
The amendments for which Findings are made are as follows. For
specific Findings, see attached narrative (Exhibit A-i) .

Findings for Local Amendments to the
2001 California Fire Code
PREAMBLE
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, 2001 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, 2001 Edition,
have been recognized by the City of Palo Alto as tools for
addressing the fire problem, 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 condi tions. 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. CLIMATIC:
The district, 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° 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 has caused 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.
Because of the weather patterns, a normal rainfall cannot
always be relied upon. This can result in water rationing and
021022 cI 0044177 64
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.
2. GEOLOGICAL/GEOGRAPHICAL:
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, 11 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 priori tized 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 sk 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;
021022 cl 0044177 6 5
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 precautions.
Transportation. Palo Al to is dissected by a major state
highway (El Camino Real) and two major freeways (1-280 and
u.s. 101), which potentially could affect response times of
fire suppression equipment.
Soil Conditions. Palo Alto lies at the southern end of San
Franc sco 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
the 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 that
depth generally 300' or more.
3. TOPOGRAPHICAL:
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,
that 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.
021022 cJ 0044177 66
The fire code amendments increase safeguards and tialize early
response to help compensate for these physical delays.
As a result of the findings of facts which identifies the various
climatic, geological/geographical and topographical elements, those
additional requirements as specified in the amendments to adopting
ordinance for the California Fire Code 2001 Edition, by the City of
Palo Alto area 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 people were killed. While it is clearly understood that the
adoption of 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.
