1 FINDINGS OF FACT AND NEED FOR
2 CHANGES OR MODIFICATIONS TO THE
3 UNIFORM FIRE CODE,1991 EDITION
4 DUE TO LOCAL CONDITIONS
5 CHANGES OR 14IODIFICATIONS: Pursuant to Section 17958 of the State of
6 California Health and Safety Code, the governing body of the City of Petaluma in its
7 ordinance adopting and amending the 1991 Edition of the Uniform Fire Code
8 changes or modifies, certain provisions of the State -Building Standards Code as it
9 pertains to the regulation of btrildings used for human habitation. A copy of the text
10 of such changes. or modifications is attached.
11 ~ Ptu scant to Sections 17958.5 and 17958.7 (a) of the State of California
12 Health and Safety Code, the .governing body of the City of Petaluma has determined
13 and finds that all the attached changes or modifications are needed and are
1 ~ reasonably necessary because of local climatic, geological and topographic
15 conditions as discussed below.
16 Local Conditions: Local conditions have an adverse effect on the prevention of (1)
17 major loss fires, (2) major earthquake damage, and (3) the potential for life and
18 property loss, making necessary changes or modifications in the Uniform Fire Code
19 and the State Building:Standards Code in order to provide a reasonable degree of
2 4 property security, and fire and life safety in the City of Petaluma.
21 Below are listed adverse local climatic (see No.l), geological and topographic (see
2 ? No. 2) conditions.
23 1.
2 4 a. Precipitation. Precipitation ranges from 20 inches to approximately
2 25 inches per year. Approximately ninety percent (909'0) falls dcn ing
2 ~ the months of November through April, and 1096 from May through
2? October. This area experienced a major drought a few years ago
Z 8 (1977-78); it is possible that more droughts will occc~ in the ftrttu~e.
2 9 b. Relative Humidity. Humidity generally ranges from 509'o during
30 daytime to 869b at might. It drops to 209'o during the summer months
31 and occasionally drops lower.
32 c. Te~,neratures. Temperatures have been recorded as high as 104
33 degiees Fahrenheit. Average summer highs are in the 78-85 degree
34 r~•
3~ d. ~iu~. Prevailing winds are from the northwest. Hawe~ver, winds
are experienced fi om virtually every direction at one time or another.
37 .Velocities .are generally in the 5 -15 mph range, ,gusting to 7.4 mph -
38 30 mph, particularly dig the summer months. Extreme winds.
39 up to 50 mph, have been known to occur.
_- - - ==.
1 e. ~L These locals climatic conditions affect the acceleration,
2 intensity, and size of fire in the community.. Times of little or no
3 rainfall, of low humidity and him temperattn es create extremely
4 hazardous conditions, particularly as they relate to wood shake and
5 shingle roof fires and conflagrations. The winds experienced in this
6 area can have a tremendous impact upon structure fires in buildings
7 in close proximity to one another, commonly found in Petaluma.
8 Winds can carry sparks and burning brands to other structtu es, thus
9 spreading the fire and causing conflagrations. In building fires,
10 winds. can literally force fires back into the building and can create a
11 blowtorch effect, in addition to preventing "natural" ventilation and
12 cross-ventilation efforts.
13 2. Geological and Topog~phic
14 a. The fire environment of a commtmity is primarily a combination of
1 ~ two factors: the area's physical geographic characteristics and. the
1 historic pattern of urban-sub~an development. These two factors,
17 alone and combined, create a mixtctre of environments which
18 ultimately determines the area's fire protection needs.
19 The basic geogxaphieal boundaries of the city include hills to the south
2 d and west, and valley floor in the central area and to the north and
21 east., The Petaluma River bisects the city-through the central area.
2 2 Be+cause.-of°the=size of the City of Petahm~g (12 square miles), the
z 3 characteristics of the fire environment changes from one location to
2 4 the~next. Therefore the city has not one; but a number of fire
2 5 environments, each of which has its individual fire protection needs.
2 6 The service: area of the City of Petaluma has; a; varied topography and
2 7 veg~etativ+e cover. A conglomeration of bay; plains, hills and ridges
2 ~ make up the terrain. Development has occurred on the flat lands in
2 9 the central and eastern of'the city. However, over the last ten years,
30 development has spread rota the hills and the smaller valleys and
31 canyons.
32 b. Seismic ration. The. relatively young geological processes that have
33 created the San Francisco BayArea are still active today. Two active
34 earthquake faults (San Andreas and the ~iealdsburg-Rodgers Creep
3~ affect the :Petaluma area. Approximately 509'0 of the City's land
3 surface is in the high-to-moderate seismic hazard zones.
37 c. Size and Ponul tion. The City of Petaluma covers 12 square miles
38 including an urban population estimated at 43,040. Within the city
39 are. three (3) fire stations and a total of 50 fire personnel. The fire
40 .department handles diverse responsibilities including wild land and
41 urban. fires, freeway, air, rail and medical emergencies.
42 d. Tono~anhv. The city's service area is. a conglomeration of bay
43 plains, hills, valleys and ridgPS. The flatter lands are found in the
2
' ~. ~' b f
` _ ^~. , _
a
1 central and eastern portions of the city. 1Vlost of the existing urban
2 and suburbanized areas are on relatively flat-lands (0 - 596) slope.
3 Futzu~e residential development is also proposed for the hill areas
4 south and west of the city. The majority of the hillsides in these areas.
5 have slopes ranging from 15 - 3096 and 30+go.
m 6 Correspondingly, there is much diversity in slope percentagES. Slope
7 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
9 factors remaining the same.
10 e. e ' ~ . Petaluma's semi-arid A~iediterranean-type climate
11 produced vegetation similar to that of most of Sonoma County.
1~ 2 Approximately half of all the strictures in the city have combustible
F 3 wood. shingle or shake roofs.. This very flammable .material is
14 susceptible to ignition by embers from a wild land fire, furthering the
15 spread of fire to adjacent buildings.
16 f. ~ The above.local geological and topographic conditions
1$ ~ presented to the C ~ o pe~~blity'problems and fire
1 ~ Fire following an-.earthquake has the' potential of causing greater loss
Z4 of life and. clamage:,than the earthquake itself. Approximately 5096 of
21 all dwellings in the city have. wood shingle roofs.
2 2 The majority of the City's industrial complexes are :located in the
2 3 highest seismic risk zones. The highest seismic risk zone also
2 4 contains the. largest concentration of hazardous materials.
2 HazardoUS materials, particularly toxic gases, could pose the greatest
2 ~ threat, to the largest number, should a significant seismic event
2 7 occtu~. The City's resources would have to be prioritized to mitigate
2 8 the greatest threat, and may ..likely be tmavailable for fires in smaller
2 9 single-dwellings .and strictures.
34 Other variables may tend to intensify the situation:
31 1) The extent of damage to the water system;
32 2) The extent of isolation due to bridge andlor freeway overpass
33 collapse;
3 ~ 3) The extent of roadway damage andlor amount of debris
35 blocking the roadways;
36 4) Climatic'conditions (hot, dry weather with high winds);

and could intensify the risk of life doing normal business
hours;
6~ The availability of timely mutual aid or assistance; from
neighboring. departments which could also have emergencies
at the same time.
'~ The large portion of dwellings with wood shingle ref
coverings could result in 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~ found to be
reasonably necessary that the. Uniform Fire Code be changed or modified to
