1 FINDINGS OF FACT AND NEED FOR
2 CHANGES OR MODIFICATIONS TO THE
3 UNIFORM FIRE CODE, 1988 EDITION
4 DUE TO LOCAL CONDITIONS
5
6 CHANGES OR MODIFICATIONS: Pursuant to Section 17958 of the State
7 of California Health and Safety Code, the governing body of the City of
8 Petaluma in its ordinance adopting and amending the 1988 Edition of the
9 Uniform Fire Code changes or modifies certain provisions of the State Building
1 0 Standards Code as it pertains to the regulation of buildings used for human
1 1 habitation. A copy of the text of such changes or modifications is attached.
12
1 3 Fin in Pursuant to Sections 17958.5 and 17958.7 (a) of the State of
1 4 California Health and Safety Code, the governing body of the City of Petaluma
1 5 has determined and finds that the attached changes or modifications are
1 6 needed and are reasonably necessary because of local climatic, geogological
1 7 and topographic conditions.
18
1 9 Local Conditions: Local conditions have an adverse effect on the prevention
2 0 of (1) major loss fires, (2) major earthquake damage, and (3) the potential for life
2 1 and property loss, making necessary changes or modifications in the Uniform
2 2 Fire Code and the State Building Standards Code in order to provide a
2 3 reasonable degree of property security, and fire and life safety in the City of
2 4 Petaluma.
25
2 6 Below are listed adverse local climatic (see No.1), geological and topographic
2 7 (see No. 2) conditions.
28
2 9 1. Climatic
30
3 1 a. Precipitation. Precipitation ranges from 20 inches to
3 2 approximately 25 inches per year. Approximately ninety percent
3 3 (90%) falls during the months of November through.April, and 10%
3 4 from May through October. This area experienced a major
3 5 drought a few years ago (1977-78); it is possible that more
3 6 droughts will occur in the future.
37
3 8 b. Relative Humidity. Humidity generally ranges from 50% during
3 9 daytime to 86% at night. It drops to 20% during the summer
4 0 months and occasionally drops lower.
41
4 2 c. Temperatures. Temperatures have been recorded as high as 104
4 3 degrees Fahrenheit. Average summer highs are in the 78-85
4 4 degree range.
45
46
47
48
49
~~~~.17 9 9 N C S
1 d. Win Prevailing winds are from the northwest. However, winds
2 are experienced from virtually every direction at one time or
3 another. Velocities are generally in the 5 - 15 mph range, gusting
4 to 7.4 mph - 30 mph, particularly during the summer months.
5 Extreme winds, up to 50 mph, have been known to occur.
6
7 e. mm These locals climatic conditions affect the
8 acceleration, intensity, and size of fire in the community. Times of
9 little or no rainfall, of low humidity and high temperatures create
1 0 extremely hazardous conditions, particularly as they relate to
1 1 wood shake and shingle roof fires and conflagrations. The winds
1 2 experienced in this area can have a tremendous impact upon
1 3 structure fires in buildings in close proximity to one another,
1 4 commonly found in Petaluma. Winds can carry sparks and
1 5 burning brands to other structures, thus spreading the fire and
1 6 causing conflagrations. In building fires, winds can literally force
1 7 fires back into the building and. can create a blowtorch effect, in
1 8 addition to preventing "natural" ventilation and cross-ventilation
1 9 efforts.
20
2 1 2. Geological and Topoaraphic
22
2 3 a. The fire environment of a community is primarily a combination of
2 4 two factors: the area's physical geographic characteristics and
2 5 the historic pattern of urban-suburban development. These two
2 6 factors, alone and combined, create a mixture of environments
2 7 which ultimately determines the area's fire protection needs.
28
2 9 The basic geographical boundaries of the city include hills to the
3 0 south and west, and valley floor in the central area and to the north
3 1 and east. The Petaluma River bisects the city through the central
3 2 area. Because of the size of the City of Petaluma (12 square
3 3 miles), the characteristics of the fire environment changes from
3 4 one location to the next. Therefore the city has not one, but a
3 5 number of fire environments, each of which has its individual fire
3 6 protection needs.
37
3 8 The service area of the City of Petaluma has a varied topography
3 9 and vegetative cover. A conglomeration of bay, plains, hills and
4 0 ridges make up the terrain. Development has occurred on the flat
4 1 lands in the central and eastern of the city. However, over the last
4 2 ten years, development has spread into the hills and the smaller
4 3 valleys and canyons.

b. Seismic Location.. The relatively young geological processes that
have created the San Francisco Bay Area are still active today.
Two active earthquake faults (San Andreas and the Healdsburg-
Rodgers Creek) affect the Petaluma area. Approximately 50% of
the City's land surface is in the high-to-moderate seismic hazard
zones.
c. Size and Po ul~ation. The City of Petaluma covers 12 square
miles including an urban population estimated at 43,000. Within
the city are three (3) fire stations and a total of 50 fire personnel.
The fire department handles diverse responsibilities including wild
land and urban fires, freeway, air, rail and medical emergencies.
d. To~o,gra~h~ The city's service area is a conglomeration of bay
plains, hills, valleys and ridges. The flatter lands are found in the
central and eastern portions of the city. Most of the existing urban
and suburbanized areas are on relatively flat lands (0 - 5%) slope.
Future residential development is also proposed for the hill areas
south and west of the city. The majority of the hillsides in these
areas have slopes ranging from 15 - 30% and 30+%.
Correspondingly, there is much diversity in slope percentages.
Slope is an important factor in fire spread. As a basic rule of
thumb, the rate of spread will double as the slope percentage
doubles, all other factors remaining the same.
e. Vegetation. Petaluma's semi-arid Mediterranean-type climate
produced vegetation similar to that of most of Sonoma County.
Approximately half 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.
Summary The above local geological and topographic conditions
increase 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. Approximately
50% of all dwellings in the city have wood shingle roofs.

1 The majority of the City's industrial complexes are located in the
2 highest seismic risk zones. The highest seismic risk zone also
3 contains the largest concentration of hazardous materials.
4 Hazardous materials, particularly toxic gases, could pose the
5 greatest threat to the largest number, should a significant seismic
6 event occur. The City's resources would have to be prioritized to
7 mitigate the greatest threat, and may likely be unavailable for fires
8 in smaller single-dwellings and structures.

1 2 1) The extent of damage to the water system;
13
1 4 2) The extent of isolation due to bridge and/or freeway
1 5 overpass collapse;

1 8 blocking the roadways;
19
2 0 4) Climatic conditions (hot, dry weather with high winds).;

2 3 and could intensify the risk of life during normal business
2 4 hours;

2 6 6) The availability of timely mutual aid or assistance; from
2 7 neighboring departments which could also have
2 8 emergencies at the same time.

3 3 Conclusion: Local climatic, geological and topographic conditions impact fire
3 4 protection efforts, and the frequency, spread, acceleration, intensity and size of
3 5 fire involving buildings in this community. Further, they impact potential
3 6 damage to all structures from earthquake and subsequent fire. Therefore it is
3 7 found to be reasonably necessary that the Uniform Fire Code be changed or
3 8 modified to mitigate the effects of the above conditions.
