1.0 CHANGES OR MODIFICATIONS Pursuant to Section 17,958 of the State of California. Health and
11 Safety Code, the governing body of the City of in its ordinance adopting, and
12 amending the 2000 Edition of the Uniform Fire Code, with California Amendments, changes or
13 modifies certain provisions of the State Building;.Standards Code as it pertains to the regulation of
14 buildings used for human habitation. A copy of the text of such changes or modifications is
15 attached.
16
17 FINDINGS Pursuant to. Sections 17958.5 and 1'7958:7(a) of the State of California Health and
18 Safety Code, the governing "body of the City of Petaluma has.dete'rmined and finds that all the
19 attached changes or modifications are needed and are reasonably necessary because of local
20 climatic, geological' and topographic conditions as discussed below.
21
22 LOCAL CONDITIONS Local ,conditions have, an adverse effect on the prevention of (1) major
23 loss fires, (2) major earthquake damage., and'(3) the potential for life „and. property loss, making
24 necessary changes or modifications in the Uniform Fire Code and the. State Building Standards
� 25 Code in order to provide a; reasonable degree of property security, and fire and life safety in the
26 City of Petaluma.
27
28 Below are listed adverse local ciimatic, geological and topographic, conditions.
29
30 CLIMATIC
31 Precipitation Precipitation ranges from 20 inches to' approximately 25 inches per year.
32. Approximately ninety percent (90 %) falls, during' the months of November through April, and 10%
33 from May through October. In 1994 - 1995, severe' flooding occurred during the months of
34 January and March 1995 and 1998.
35
36 Relative Humidity Humidity, generally ranges from 50% during daytime 86% at night. It drops to
37 20 %.during the summer months and occasionally drops lower during the months of September
38 through. November.
39
40 Temperatures Temperatures have been recorded as high as 104 degrees Fahrenheit. Average
41 summer highs are.in thel 78= 85degree range.
42
43 Winds Pre'vailing. winds are 'from the northwest. However, winds are experienced from virtually
44 every direction•at , time-or, + another Velocities are, generally in the 5 -15 mph range, gusting
45 to 7.4, -30 mph, particularly during the s "ummer months. Extreme winds, up 10 50 mph, have been
46 known to occur.
47
48 Summary These local climatic conditions affect the acceleration "intensity, 'and size of fire in the
49 community. Times, of little or ho rainfall, of low humidity and high temperatures create extremely
&0 hazardous conditions;: particularly as they relate to wood shake and shingle roof fires and
Ordinance No. 2194 N.C.S. Page 6
g experienced in this area can have a tremendous impact upon
2 structure, fires in buildings i close proximity to one another. Winds can carry sparks and burning
_ ,
3 branches to other structures, thus spreading the fire and causing conflagrations. In building fires,
4 winds can literally force fires back' into the building and create a blowtorch..effect, in addition to
5 preventing "natural" ,ventilation and cross -ven ilation efforts. In -the City's Historic Downtown
6 Business ,District particularly, these conditions can create an extremely 'hazardous situation
7 because of .the densely situated buildings in that district, many of which are large„ old, wooden
8 buildings built without fire protection.
9
10 GEOLOGICAL AND, TOPOGRAPHIC
11, The fire environment of a community is primarily a combination of two factors: 'the area's
12 . physical geographic characteristics and- the historic pattern of urban- suburban development:
13 These two factors, alone and combined, create a mixture of environments which- ultimately
14 determine the area's fire protection needs.
15
16 The r basic geographical boundaries of the city include hills to the ; so.uth and west, and valley
17 floor in the central area and to the north and east. The Petaluma River .bisects the city through
18 the central area. Because, of the. size' of the City of Pefaluma (,I,' , 2 square miles), the
19 characteristics of the fire environment, changes from one,location to the next. Therefore the city
20 has not one, but a number of, fire 'environments; each of which has its individual lire protection
,21 needs:
22
23' The service area of the City of Petaluma has a varied topography , and vegetative cover. A
24 conglomeration of b- ay, plains, hills and ridges make up the terrain. Development has occurred
25 on the flatlands -in the central and portions of the city. However, over-the last °tenyears,
26 clevelo p ment has spr6ad_'into the hills and the smaller valleys and canyons'
2,7
28' Seismic Location The relatively young geological processes that have creafed the San
29 Francisco .Bay Area 'are still active today. Two active earthquake faults (San Andreas and the
30 Healdsburg- Rodgers 'Creek) affect the Petaluma area. .Approximately 50% of 'the'. city's land
31 surface is in the high- to- moderafe seismic hazard - zones.
32
3,3 Size and Population The, City of Petaluma covers 12 square miles including an urban population
34 estimated'at 56;000. Within the city are three (3) fire stations and a total,of"54 fire personnel. The
35 . Fire Department` handles diverse responsibilities including wild land and urban fires,, freeway, air;
36 rail and medical 'emergencies.
37
38 T000araphv The city's, service area is a conglomeration of ,bay plains, hills, valleys, and. ridges.
39 The flatter Idnds are found in the central and eastern. portions of the city. Most of the existing
40 urban and suburbanized areas are on relatively-flat lands - 5 %) slope.
41
p proposed for the hill areas south and vv
42 Future residential'd'evelo ment;is also est of the city. The
43 majority ,of thet hillsides in these areas 'have slopes ranging from 15 - 30 %. Correspondingly, there
44 is much diversity in slope percentages. Slope is an important factor in fire spread. As a basic
45 rule, of thumb, the rate of spread:-will double as the slope., percentage: doubles, all other factors
46 remaining the same.
47
48, Vecietation Petaluma's semi -arid Mediterranean -type climate produces vegetation similar to
49 that of most of, Son County:
50
Ordinance No.2194 N'.C.S. 'Page 7
1 Approximately half of all the.structures in the city have combustible wood- shingle or shake roofs.
2 This very flammable material is susceptible to ignition by embers from a wild land fire, furthering
3 the spread of fire - to adjacent buildings.

6 exposure, accessibility problems, and fire hazards r se once the magnitude,
5 Summary The above local geological and topographic conditions enh
7 following an earthquake has' the potential of causing presented to the City of Petaluma. Fire
8 earthquake itself. g greater toss of life and damage than the
9
10 The majority of the ,City's industrial complexes are located in. the highest seismic risk zones. The
11 highest seismic risk ; zone . also contains the largest :concentration of hazardous materials.
12 Hazardous materials particularly toxic gases, could pose the
13 number, should a significant" seismic event - occur. The. City's g hreat toh the
e largest. be
14 prioritized to mitigate the greatest' threat; and may likely be unavailable for fires in smaller single -
15 dwellings and structures,
1.6
17 Other variables may fend,fb intensify the situation:
18
19 The extent of damage to -the water system, the extent of isolation due to bridge and /or freeway
20 overpass collapse,. the extent of roadway damage and /or am'ounf of debris blocking the
21 roadways, climatic conditions (hot, dry weather with high winds); time of day will influence the
22 amount of traffic on roadways and could intensify the ri
23 sk of life during normal business hours.
24 The availability of timely mutual did or assistance from neighboring departments, which could
25 also have emergencies at the same time. The large portion of dwellings with wood shingle roof
0' 26 coverings could result in conflagrations;
7
2 8 The dense configuration of olden ;wooden buildings in the Historic Downtown Business District
29 would also be susceptible to conflagration which possibly can be mitigated by requiring the
30 - additional fire protection measures provided in this ordinance.
31
32 CONCLUSION
33 Local climatic, geological and topographic conditions impact fire protection efforts, and the
34 frequency, spread, acceleration, :intensity and, size of fire involving ,buildings in this community.
35 Further, they impact potential damage to all structures from earthquake and subsequent fire.
36 Therefore it is found to b, & reasonably necessary that the Uniform fire ' Code be changed or
37 modified to mitigate the effects of the above conditions.
