EXHIBIT A
FINDINGS OF FACT AND NEED FOR CHANGES OR MODIFICATIONS TO THE CALIFORNIA
FIRE CODE, 2022 EDITION WITH CALIFORNIAAMENDMENTS, DUE TO LOCAL CONDITIONS
CHANGES OR MODIFICATIONS: Pursuant to Section 17958 of the State of California Health and Safety
Code, the governing body of the City of Petaluma in its Ordinance adopting and amending the 2022 Edition of
the California Fire Code, changes or modifies certain provisions of the California Building Standards Code as it
pertains to the regulation of buildings used for human habitation. A copy of the text of such changes or
modifications is attached.
FINDINGS: Pursuant to Sections 17958.5 and 17958.7(a) of the State of California Health and Safety Code, the
governing body of the City of Petaluma has determined and finds that all the attached changes or modifications
are needed and are reasonably necessary because of local climatic, geological and topographic conditions as
discussed below.
LOCAL CONDITIONS: Local conditions have an adverse effect on the prevention of(1)major loss fires, (2)
major earthquake damage and(3) the potential for life and property loss, making the changes or modifications
in the California Fire Code and the State Building Standards Code necessary in order to provide a reasonable
degree of property security and fire and life safety in the City of Petaluma.
Below are adverse local climatic, geological and topographic conditions that necessitate the modifications to the
California Fire Code and California Building Standards Code.
CLIMATIC (a)
Precipitation: Precipitation ranges from twenty inches (20") to approximately twenty-five inches (25")per year.
Approximately ninety percent(90%) falls during the months of November through April and ten percent(10%)
from May through October. Severe flooding occurred during the months of January and March, 1995 and in
1998 and 2006.
Relative Humidity: Humidity generally ranges from fifty percent(50%) during daytime and eighty-six percent
(86%) at night. It drops to twenty percent(20%) during the summer months and occasionally drops lower
during the months of September through November.
Temperatures: Temperatures have been recorded as high as 104 degrees Fahrenheit. Average summer highs are
in the 78-85 degree range.
Ordinance No. 2835 N.C.S. Page 32
DocuSign Envelope ID:All B06B84-EE7D-422E-AEAB-0A1 8303939E4
Winds: Prevailing winds are from the northwest. However, winds are experienced from virtually every direction
at one time or another. Velocities are generally in the 5-15 mph range, gusting to 7.4-30 mph, particularly
during the summer months. Extreme winds,up to 50 mph,have been known to occur.
Summary: These local climatic conditions affect the acceleration, intensity, and size of fires in the community.
Times of little or no rainfall, of low humidity and high temperatures create extremely hazardous conditions,
particularly as they relate to wood shake and shingle roof fires and conflagrations. The winds experienced in
this area also adversely impact structure fires in buildings in close proximity to one another. Winds can carry
sparks and burning branches to other structures, thus spreading the fire and causing conflagrations. In building
fires, winds can literally force fires back into the building and create a blowtorch effect, in addition to
preventing natural ventilation and cross-ventilation efforts. Petaluma's downtown and surrounding areas contain
numerous historic and older buildings that are located very close together, which exacerbates the fire danger
from dry conditions, wind, and shake/shingle roofs.
TOPOGRAPHIC N
The topographic fire environment of a community is primarily the combination of two factors: the area's
physical geographic characteristics and the historic pattern of urban-suburban development. These two factors,
alone and combined, create a mixture of environments which ultimately determine the areas' fire protection
needs.
The basic geographical boundaries of the City include hills to the south and west, and valley floor in the central
area and to the north and east. The Petaluma River bisects the City through the central area. The City of
Petaluma covers thirteen(13) square miles and contains an urban population estimated at 58,000. The City's
service area is a conglomeration of bay,plains, hills, valleys, and ridges. Currently,within the City, are three (3)
fire stations and fifty-three (53) fire personnel (58 when fully staffed). Because of the size of the City of
Petaluma, the characteristics of the fire environment changes from one location to the next. For example, the
central downtown area contains older buildings situated close together, which increases the ability of fire to
spread from one building to the next. In contrast, some of the properties on the outlying hills are far apart, but
contain large grassy acreages that promote quickly-spreading wildfires during the long dry season.
The City's development pattern also contributes to its unique fire protection needs. Development has
traditionally occurred on the flat lands (0—5% slope) in the central and eastern portions of the City. However,
over the last ten(10) years, development has spread into the hills and the smaller valleys and canyons. This
development has significantly increased the service area for the City's fire department and has added
complicated logistical challenges for getting fire equipment to remote fires or fires on steep hillsides. The
majority of the hillsides in these areas have slopes ranging from 15 - 30%. As a basic rule of thumb, the rate of
spread will double as the slope percentage doubles, all other factors remaining the same.
The local vegetation further contributes to fire dangers in the City. Petaluma's semi-arid Mediterranean-type
climate produces vegetation similar to that of most of Sonoma County. In the long periods of the year with little
or no rain (April through October), this vegetation provides ready fuel for fast-spreading wildfires.
Moreover, some of the structures in the City have combustible wood-shingle or shake roofs. This very
flammable material is susceptible to ignition by embers from a wild land fire, furthering the spread of fire to
adjacent buildings.
GEOLOGICAL (0
The above local topographic conditions enhance the magnitude, exposure, accessibility problems, and fire
hazards presented to the City of Petaluma. Fire following an earthquake has the potential of causing greater loss
of life and damage than the earthquake itself.

The relatively young geological processes that have created the San Francisco Bay Area are still active today.
Two (2) active earthquake faults (San Andreas and Hayward-Rodgers Creek) affect the Petaluma area.
Approximately fifty percent(50%) of the City's land surface is in the high-to-moderate seismic hazard zones.
The majority of the City's industrial complexes are located in the highest seismic risk zones. The highest
seismic risk zone also contains the largest concentration of hazardous materials. Hazardous materials,
particularly toxic gases, could pose the greatest threat to the largest number people, should a significant seismic
event occur. The City's resources would have to be prioritized to mitigate the greatest threat, and may likely be
unavailable for fires in smaller single-dwellings and structures.
Other variables that may intensify the fire danger after a major seismic event include:
• The extent of damage to the water system;
• The extent of isolation due to bridge and/or freeway overpass collapse;
• The extent of roadway damage and/or amount of debris blocking the roadways;
• Climatic conditions (hot, dry weather with high winds);
• Time of day, which will influence the amount of traffic on roadways and could intensify the risk to life
during normal business hours;
• The availability of timely mutual aid or assistance from neighboring departments, which will likely have
similar emergencies at the same time; and
• The large portion of dwellings with wood shingle roof coverings, which will increase the likelihood of
conflagrations.
CONCLUSION
Local climatic, geological and topographic conditions impact fire protection efforts, and the frequency, spread,
acceleration, intensity and size of fire involving buildings in this community. Further, they impact potential
damage to all structures from earthquake and subsequent fire. Therefore, it is reasonably necessary that the
California Fire Code be changed or modified to mitigate the effects of the above conditions. Theses local
climactic and geological conditions have necessitated these minor modifications to the Title 24, Part 9,
California Fire Code.
SECTION 4. SEVERABILITY. If any part of this Ordinance is for any reason held to be unconstitutional,
unlawful or otherwise invalid by a court of competent jurisdiction, such decision will not affect the validity of the
remaining parts of this Ordinance. The City Council of the City of Petaluma hereby declares that it would have
passed and adopted this Ordinance and each of its provisions irrespective of any part being held invalid.
SECTION 5. CEQA. The City Council finds that this Ordinance is not subject to the California Environmental
Quality Act ("CEQA") pursuant to Section 15060(c)(2) of the CEQA Guidelines because the activity has no
potential for resulting in a direct or reasonably foreseeable indirect physical change in the environment, and
pursuant to Section 15060(c)(3)of the CEQA Guidelines because the activity is not a project as defined in Section
15378) of the CEQA Guidelines.
If the Ordinance was a"project"pursuant to CEQA it would be exempt pursuant to CEQA Section 15061(b)(3)
(common sense exemption) since This action involves updates and revisions to existing regulations consistent
with State law and will not result in any direct or indirect physical changes to the environment The proposed
amendments are also exempt from CEQA in accordance with Section 15307 of the CEQA Guidelines as an
action taken by the City as authorized by state law to assure the maintenance, restoration or enhancement of a
natural resource where the regulatory process involves procedures for protection of the environment, in
accordance with the findings in the attached ordinance. The proposed amendments are also exempt from CEQA
