1 SECTION 2: FINDINGS
2
3 The City Council of the City of Petaluma finds that in order to best protect the health,
4 safety and welfare of the citizens of the City of Petaluma, the standards of building within the
5 City must conform with state law except where local climatic, geological, and topographic
6 conditions warrant more restrictive regulations. Therefore, the City Council should adopt the
7 current state building codes, contained in California Building Standards Code Title 24, and other
8 uniform codes governing the construction and regulation of buildings and structures with the
9 modifications and amendments contained herein.
10
11 Pursuant to California Health and Safety Code Section 17958.7, the City Council makes
12 the factual findings set forth in "Exhibit A" attached hereto and incorporated herein by
13 reference, and finds that the amendments made in this ordinance to the California Building
14 Standards Code Title 24, Parts 1, 2, 2.5, 3, 4, 5, 6, 8, 10, and 12, are reasonably necessary
15 because of the local climatic, geological or topographical conditions described in Exhibit A.
16
17 Pursuant to California Public Resources Code Section 25402.1 and California Code of
18 Regulations, Title 24, Part 1, Article 1, Section 10 -106 (Locally Adopted Energy Standards), a city
19 may require additional energy conservation measures and set more stringent energy budgets in
20 a local green building ordinance than the standards set forth in the California Energy Code if the
21 city demonstrates the energy cost- effectiveness of the standards and files with the California
22 Energy Commission the basis of the city's determination that the standards are cost effective.
23 This determination that the standards are cost effective must be adopted by the governing
24 body at a public meeting. Based on the Climate Zone 2 Energy Cost - Effectiveness Study
25 attached hereto as Exhibit "B" and incorporated herein by reference, the City Council hereby
26 finds and determines that the energy standards adopted in the California Green Building Code,
27 Title 24, Part 11, as amended herein, are cost effective.
28
29 SECTION 3: CURRENT BUILDING CODES ADOPTED

FINDINGS OF FACT AND NEED FOR CHANGES OR MODIFICATIONS
TO THE CALIFORNIA BUILDING STANDARDS CODE TITLE 24,
PARTS 1, 2, 2.5, 3, 4, 5, 6, 8, 10, 11, AND 12
EXHIBIT A
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 2010 Editions of the California Building Standards Administrative Code; California
Building Code; California Residential Building Code; California Electrical Code; California
Mechanical. Code; California Plumbing Code; California Energy Code; California Historical
Building Code; California Existing Building Code; California Green Building Standards Code and
California Reference Standards 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 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 Building Standards Code.
CLIMATIC
Precipitation Precipitation ranges from twenty inches (20 ") to approximately twenty -five inches
(25 ") per year. Approximately ninety percent (900) 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 (860) 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.
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.
Soils: Much of Petaluma has "Adobe" soil. This soil has very high clay content and is extremely
expansive. With Petaluma's dry summers and wet winters, the moisture content of the soil varies
greatly during the course of the year. This moisture content change causes
expansion /contraction of the clay soil. This expansion /contraction can place large loads on
concrete slabs and foundation systems making some "standard" foundation methods /materials
inappropriate for the local conditions encountered.
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
The topographic fire environment of a community is primarily a combination of two (2) factors:
the area's physical geographic characteristics and the historic pattern of urban- suburban
development. These two (2) 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 13 square miles, including an urban population
estimated at 57,000. The city's service area is a conglomeration of bay, plains, hills, valleys, and
ridges. Within the City are three (3) fire stations and fifty -six (56) fire personnel. 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 for 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 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 all 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
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 the Hayward- Rodgers Creek)
affect the Petaluma area. Approximately fifty percent (500) 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 of persons, 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 of 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 will increase the likelihood of
conflagrations.

ENVIRONMENTAL
Design and construction methods, and materials used in the construction of new buildings can
have a large impact on the City's environmental sustainablity, energy usage, waste
management, and the health and productivity of its citizens and visitors.
The new CalGreen requirements will have a significant, positive effect on, resource conservation,
energy usage, waste and pollution control, and the health and productivity of the citizens and
visitors of the City of Petaluma
CalGreen offers regulations titled "Tier One" which contain even higher standards of all the
regulated features within its regulations. Making Tier One's optional requirements mandatory will
help the City of Petaluma to achieve greater levels of health and productivity for its citizens and
visitors to the City of Petaluma
Requiring new commercial and residential projects to incorporate CalGreen Tier One standards
is appropriate to help Petaluma achieve its goal of raising public health and welfare benefits for
its citizens and visitors in a more timely fashion.
DEFINITION CLARIFICATION
Due to code enforcement problems in the past, the description of buildings not requiring permits
was expanded to help clarify when permits are /are not required.
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 found to be reasonably necessary that the California Fire Code be changed or
modified to mitigate the effects of the above conditions.
The local climatic, environmental, and geological conditions necessitate the modifications to
the California Building Codes (Title 24).
