7
8 CHANGES OR MODIFICATIONS Pursuant to Section 17958 of the State of California Health and
9 Safety Code, the governing body of the City of Petaluma in its ordinance adopting and
10 amending the 2010 Editions of the California Building Standards Administrative Code; California
11 Building Code; California. Residential. Building Code; California Electrical Code; California
12 Mechanical Code; California Plumbing Code; California Energy Code; California Historical
13 Building Code, California Existing Building Code; California Green Building Standards Code and
14 California Reference Standards Code, changes or modifies certain provisions of the California
15 Building Standards Code as it pertains to the regulation of buildings used for human habitation.
16 A copy of the text of such changes or modifications is attached.
17
18 FINDINGS Pursuant to Sections 17958.5 and 17958.7 (a) of the State of California Health and
19 Safety Code, the governing body of the City of Petaluma has determined and finds that all the
20 attached changes or modifications are needed and are reasonably necessary because of local
21 climatic, geological and topographic conditions as discussed below.
22
23 LOCAL CONDITIONS Local conditions have an adverse effect on the prevention of (1) major
24 loss fires, (2) major earthquake damage, and (3) the potential for life and property loss, making
25 the changes or modifications in the California Building Standards Code necessary in order to
26 provide a reasonable degree of property security, and fire and life safety in the City of
27 Petaluma.
28
29 Below are adverse local climatic, geological and topographic conditions that necessitate the
30 modifications to the California Building Standards Code.
31
32 CLIMATIC
33
34 Precipitation Precipitation ranges from twenty inches (20 ") to approximately twenty -five inches
35 (25 ") per year. Approximately ninety percent (90 %) falls during the months of November through
Ordinance No. 2393 N.C.S. Page 16
1 April, .and ten percent (10 %) from May through October. Severe flooding occurred during the
2 months of January and March, 1995 and in 1998 and 2006.
3
4 Relative Humidity Humidity generally ranges from fifty percent (50 %) during daytime and eighty -
5 six percent (86 %) at night. It drops to twenty- percent (20 %) during the summer months and
6 occasionally drops lower during the months of September through November.
7
8 Temperatures Temperatures have been recorded as high as 104 degrees Fahrenheit. Average
9 summer highs are in the 78 -85 degree range.
10
11 Winds Prevailing winds are from the northwest. However, winds are experienced from virtually
12 every direction at one time or another. Velocities are generally in the 5 -15 mph range, gusting to
13 7.4 -30 mph, particularly during the summer months. Extreme winds, up to 50 mph, have been
14 known to occur.
15
16 Soils': Much of Petaluma has "Adobe" soil. This soil has very high clay content and is extremely
17 expansive. With Petaluma's dry summers and wet winters, the moisture content of the soil varies
18 greatly during the course of the year. This moisture content change causes
19 expansion /contraction of the clay soil. This expansion /co.ntraction can place large loads on
20 concrete slabs and foundation systems making some "standard" foundation methods /materials
21 inappropriate for the local conditions encountered.
22
23 Summary These local climatic conditions affect the acceleration, intensity, and size of fires in the
24 community. Times of little or no rainfall, of low humidity and high temperatures create extremely
25 hazardous conditions, particularly as they relate to wood shake, and shingle roof fires and
26 conflagrations. The winds experienced in this area also adversely impact structure fires in
27 buildings in close proximity to one :another. Winds can carry sparks and burning branches to
28 other structures, thus spreading the fire and causing conflagrations.. In building fires, winds can
29 literally force fires back into the building and create a blowtorch effect, in addition to
30 preventing "natural" ventilation and' cross- ventilation efforts. Pe,taluma's downtown and
31 surrounding areas contain numerous historic and older buildings that are located very close
32 together, which exacerbates the fire danger from dry conditions, wind, and shake /shingle roofs.

1 TOPOGRAPHIC
2
.3 The topographic fire environment of a community is primarily a combination of two (2) factors:
4 the area's physical geographic characteristics and the historic pattern of urban - suburban
.5 development. These two (2) factors, alone and combined, create a mixture of environments
6 which ultimately determine the areas' fire protection needs.
7
8 The basic geographical boundaries of the city include hills to the south and west, and valley
9 floor in the central area and to the north and east. The Petaluma River bisects the city through
10 the central area. The City of Petaluma covers 13 square miles, including an urban population
11 estimated at 57,000. The city's service area is a conglomeration of bay, plains, hills, valleys, and
12 ridges. Within the City are three (3) fire stations and fifty -six (56) fire personnel. Because of the
13 size of the City of Petaluma, the�characteristics of the fire environment changes from one
14 location to the next. For example, the central downtown area contains older buildings situated
15 close together, which increases the. ability of fire to spread from one building to the next. In
16 contrast, some of the properties on the outlying hills are far apart, but contain large grassy
17 acreages that promote quickly- spreading wildfires during the long dry season.
18
19 The city's pattern also, contributes to its unique fire protection needs.
20 Development has traditionally occurred on the flat lands (0 - 5% slope) in the central and
21 eastern portions of the city. However, over the last ten (10) years, development has spread into
22 the hills and the smaller valleys and canyons. This development has significantly increased the
23 service area for the city's fire_ department and added complicated logistical challenges for
24 getting fire equipment, to remote fires or fires on steep hillsides. The majority of the hillsides in
25 these areas have slopes ranging from 15 - 30 %. As a basic rule of'thumb, the rate of spread will
26 double as the slope percentage doubles, all other factors remaining the same.
27
28 The local vegetation further contributes to fire dangers in the city. Petaluma's semi -arid
29 Mediterranean -type climate produces vegetation similar to that of most of Sonoma County. In
30 the long periods of the year�with little or no rain (April through October), this vegetation provides
31 ready fuel for fast - spreading wildfires.
32
33 Moreover, some of all the structures in the city have combustible wood - shingle or shake roofs.
34 This very flammable material is susceptible to ignition by embers from a wild land fire, furthering
35 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 (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 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 majorseismic event include:
• The extent of damage to. the water system;
• The extent of isolation due to bridge and /or freeway overpass collapse;
• The extent 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.materia used in the construction of new buildings can
have a large impact on the City's environmental sustainability, 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)..
