the International Association of Plumbing and Mechanical
13 Officials, and the National Electrical Code of the National
Fire Protection Association (hereinafter referred to
14 collectively as "Codes"; and
15 W~EREAS, Health and. Safety Code Section 17958.5 (a) permits
the City to make modifications or changes to the Codes, which
16 are'reasonably necessary because of local climatic, geological
or topographical conditions; and
17
W~EREAS, Health and Safety Code' Section 17958.7 provides that
18 before making any modifications or changes to .the Codes, the'
City Council shall make an express finding that such changes
19 or modifications are reasonably necessary because of local
climatic, geological or topographical conditions; and
20
W~EREAS, the Community Development Department and Orange
21 County Fire Authority have recommended that changes and
modifications be made to the Codes and have advised that
22 certain said changes and modifications to the Uniform Fire
Code, 1994 Edition, are reasonably necessary due to local
23 conditions in the City and have further advised that the
remainder of said changes and modifications are of an
24 administrative or procedural nature, or concern themselves
with subjects not covered by the Codes or are reasonably
25 necessary to safeguard life and property within the City.
26 NOW, THEREFORE, BE IT RESOLVED by the City Council of the City
of Tustin as follows:
27
28 1
1 SECTION 1. The following changes and modifications to the
1994 Uniform Fire Code, as recommended by the Orange County
2 Fire Authority and the City Building Official, are hereby
found to be reasonably necessary due to the following local
3 conditions. The specific code language of each of the
following changes or modifications is located in City of
4 Tustin Ordinance Number 1159 attached hereto.
5 A. UFC Section 1003.2.2 Required Installation of Automatic
Fire Extinguishing Systems, is amended to establish fire
6 sprinkler requirements for all buildings 6,000 square
feet or larger or three stories or taller. Applies to all
7 occupancy groups other than residential (Group R-l, R-3,
and U).
8
B. UFC Section 1003.2.8 Required Installation of Automatic
9 Fire Extinguishing Systems, is amended to establish fire
sprinkler requirements for all multi-family residential
10 buildings (Group R-l) and for single family and duplex
residences (Group R-3) when the total area of the
11 building exceeds 5,500 square feet.
12 These 'amendments are reasonably necessary because of the
following conditions:
13
Climatic Conditions:
14
1. The City of Tustin is located in a semi-arid
15 Mediterranean type climate. It annually experiences
extended periods of high temperatures with little or no
16 precipitation. Hot, dry foehn (Santa Ana) winds, which
may reach speeds of 70 m.p.h., or greater, are also
17 common to the area. These climatic conditions cause
extreme drying of vegetation and common building
18 materials and predispose the area to large destructive
fires (conflagration).
19
2. The City's climate alternates between extended periods of
20 drought and brief flooding conditions. Water demand in
this densely populated area far exceeds the quantity
21 supplied by natural precipitation; and although the
population continues to grow, the already taxed water
22 supply does not.
23 California is projected to increase in population by
nearly 10 million over the next quarter of a century of
24 that 50 percent of that growth centered in southern
California.
25
3. These dry climatic conditions and winds contribute to the
26 rapid spread of even small fires originating in high
density housing.or vegetation. These fires spread very
27 quickly and create a need for increased levels of fire
28 2
1 protection. The added protection of fire sprinkler
systems will supplement normal fire department response
2 by providing immediate protection for the building
occupants and by containing and controlling the fire
3 spread to the area of origin. Fire sprinkler systems
will also reduce the use of water for fire fighting by as
4 much as 50 to 75 percent.
5 Topoqraphical Conditions:
6 1. Traffic and circulation congestion is an artificially
created, obstructive topographical condition, which is
7 common in the City of Tustin and throughout Orange
County.
8
2. These topographical conditions combine to create a
9 situation which places fire department response time to
fire occurrences at risk, and makes it necessary to
10 provide automatic on-site fire extinguishing systems to
protect occupants and property.
11
Geoloqical Conditions:
12
1. The City of Tustin is located in an area of high seismic
13 activity. The Newport-Inglewood Fault, located west of
the City, poses the greatest hazard to life and property.
14 It is believed that this fault is capable of generating
a maximum credible 7.5 magnitude earthquake. Because of
15 the degree of City's urbanization and close proximity to
a major fault, the risk of structural damage and loss of
16 life due to ground shaking is considerable.
17 2. Major earthquakes are always accomplished by disruption
of traffic flow and fires. During a major earthquake,
18 fire department resources would be extremely taxed, and
the ability to respond to fires would be complicated and
19 in some cases impossible. On-site fire extinguishing
systems would provide a degree of protection from fires
20 even if water mains are damaged or destroyed.
21 C. UFC Section 1003.2 Required Installation of Automatic
Fire Extinguishing Systems, is amended to require the
22 installation of automatic fire sprinklers in all
buildings located within a Very High Fire Hazard Severity
23 Zone.
24 These amendments are reasonably necessary because of the
following conditions:
25
Climatic Conditions:
26
27
28 3
1 1. The City of Tustin is located in semi-arid Mediterranean
type climate. It annually experiences extended periods
2 of high temperatures with little or no precipitation.
Hot, dry foehn (Santa Ana) winds, which may reach speeds
3 of 70 m.p.h., or greater, are also common to the area.
These climatic conditions cause extreme drying of
4 vegetation and common building materials and predispose
the area to large destructive fires (conflagration).
5
2. The climate alternates between extended periods of
6 drought and brief flooding conditions. Water demand in
this densely populated area far exceeds the quantity
7 supplied by natural precipitation; and although the
population continues to grow, the already taxed water
8 supply does not.
9
California is projected to increase in population by
10 nearly 10 million over the next quarter of a century of
that 50 percent of that growth centered in southern
11 California.
12 3. These dry climatic conditions and winds contribute to the
rapid spread of even small fires originating in high
13 density housing or vegetation. These fires spread very
quickly and create a need for increased levels of fire
14 protection. The added protection of fire sprinkler
systems will supplement normal fire department response
15 by providing immediate protection for the building
occupants and by containing and controlling the fire
16 spread to the area of origin. Fire sprinkler systems
will also reduce the use of water for fire fighting by. as
17 much as 50 to 75 percent.
18 Topoqraphical Conditions:
19 1. Traffic and circulation congestion is an artificially
created, obstructive topographical condition, which is
20 common in the City of Tustin and throughout Orange
County.
21
2. These topographical conditions combine to create a
22 situation which places fire department response time to
fire occurrences at risk, and makes it necessary to
23 provide automatic on-site fire extinguishing systems to
protect occupants and property.
24
Geoloqical Conditions:
25
1. The City of Tustin is located in an area of high seismic
26 activity. The Newport-Inglewood Fault, located west of
the City, poses the greatest hazard to life and property.
27 It is believed that this fault is capable of generating
28 4
1 a maximum credible 7.5 magnitude earthquake. Because of
the degree of City's urbanization and close proximity to
2 a major fault, the risk o[ structural damage and loss of
life due to ground shaking is considerable.
3
2. Major earthquakes are always accomplished by disruption
4 of traffic flow and fires. During a major earthquake,
fire department resources would be extremely taxed, and
5 the ability to respond to fires would be complicated and
in some cases impossible. On-site fire extinguishing
6 systems would provide a degree of protection from fires
even if water mains are damaged or destroyed.
7
D. UFC Section 1004.2 - STANDPIPES, is amended to require
8 additional fire department access doors or additional
standpipe outlets for buildings with a horizontal
9 dimension greater than 300 feet.
10 These amendments are reasonably necessary because of 'the
following conditions:
11
Topoqraphical Conditions:
12
1. Traffic and circulation congestion is an artificially
13 created, obstructive topographical condition, which is
common in the City of Tustin and Orange County.
14
2. Large commercial/industrial buildings, with a horizontal
15 dimension of 300 feet or greater, create an unusual
topographical condition. Portions of these buildings
16 cannot be reached with a fire hose line on initial
attack.
17
3. These topographical conditions combine to create a
18 situation which places fire department response time to
fire occurrences at risk and makes it necessary to
19 provide additional on-site fire fighting resources.
20 E. UFC Section 1008 - SPECIAL PROVISIONS FOR HIGH RISE
BUILDINGS, is amended to require specific high-rise
21 provisions for buildings which exceed 55 feet in height.
22 These amendments are reasonably necessary because of the
following conditions:
23
Topoqraphical Conditions:
24
1. The City of Tustin has an urban atmosphere which is
25 reflected in building and building complex design and
features. Landscaping and other building'features often
26 preclude or greatly limit approach or operational access
by fire department vehicles. The UBC high rise
27 provisions were developed to provide for fire department
28 5
1 laddering capabilities and response time in a downtown
Los Angeles or New York setting. These older cities
2 typically have high rise buildings which are constructed
close to the street, but in Tustin and Orange County,
3 high rise buildings typically have side yards and
landscaping.
4
2. The high rise building itself creates an unusual
5 topographical condition. High rise building fire history
shows that many people evacuate to the roof area,
6 especially if they are above the fire floor. Utilization
of helicopters is very common in these types of fires and
7 is often the only method which can be used for evacuation
or access to the fire.
8
F. UFC Section I109.7 - CONTROL OF SOURCES OF IGNITION, is
9 amended to require chimney spark arresters on all new
devices that burn any solid or liquid fuel.
10
These amendments are reasonably necessary because of the
11 following conditions:
12 Climatic Conditions:
13 1. The City is located in a semi-arid Mediterranean type
climate. It annually experiences extended periods of
14 high temperatures with little or no precipitation, which
causes extreme drying of vegetation and common building
15 materials.
16 2. The City of Tustin is also subject to extreme foehn
(Santa Ana) wind conditions which further contribute to
17 drying and rapid spread of fire.
18 3. These climatic conditions combine to create a unique
situation where vegetation and building materials are the
19 driest during the winter months. Fireplaces are most
frequently used during this time, and flying embers
20 become a hazard for building materials or vegetation in
the general area.
21
G. UFC Section 5202 Flmmmable and Combustible Liquid Motor
22 Vehicle Fuel-Dispensing Stations is amended to allow the
Chief toapprove temporary above-ground fuel tanks within
23 certain guidelines which are consistent with motor
vehicle fuel dispensing from exterior storage above-
24 ground tanks.
25 These amendments are reasonably necessary because of the
following conditions:
26
Geoloqical Conditions:
27
28 6
1 1. The City is located in an area of high seismic activity.
the Newport-Inglewood Fault is close to the City, and
2 poses the greatest hazard to life and property. It is
believed that this fault is capable of generating a
3 maximum credible 7.5 magnitude .earthquake. Because of
the degree of the City's urbanization and close proximity
4 to 'a major fault, the risk of a potential spill of
flammable/combustible liquids at these locations is
5 considerable.
6 2. Major.earthquakes are always accomplished by disruption
Of traffic flow and fires.- During a major earthquake,
7 fire department resources would be extremely taxed, and
ability to respond to fires and spills of flammable
8 combustible liquids would be complicated and in some
cases impossible.
9.
Topoqraphical Conditions;
10
1. The City has an urban atmosphere which is reflected in
11 building and building complex design and features.
12 Landscaping and other building features often preclude or
greatly limit approach or operational access by fire
13 department vehicles. With the dense urban areas close
together, the chance of a spill or spread of such
14 chemicals is a considerable threat.
15 H. UFC Article 64 Stationary Lead-Acid Battery Systems is
added to be consistent with the provisions of 1995
16 UniformFire Code Supplement and provides for regulations
for such installations.
17
These amendments are reasonably necessary because of the
18 following conditions:
19 Geoloqical Conditions:
20 1. The City is located in an area of high seismic activity.
the Newport-Inglewood Fault is close to the City, and
21 posed the greatest hazard to life and property. It is
believed that his fault is capable of generating a
22 maximum credible 7.5 magnitude earthquake. Because .of
the City's urbanization and close proximity to a major
23 fault, the risk of a potential hazardous materials spill
is considerable.
24
2. Major earthquakes are always accompanied by disruption of
25 traffic flow and fires. During a major earthquake, fire
department resources would be extremely taxed, and .the
26 ability to respond to fires and spills of battery acid at
such sites would be complicated and in some cases
27 impossible.
28 7
i I. UFC Article 80 Hazardous Materials, Section 8001 Exterior
Storage is added to be consistent with the 1995 Uniform
2 Fire Code Supplement and provides for procedures for such
outdoor storage.
3
These amendments are reasonably necessary because of the
4 following conditions:
5 Geoloqical Conditions:
6 1. The City is located in an area of high seismic activity.
The Newport-Inglewood Fault is close to the City, poses
7 the greatest hazard to life and property. It is believed
that this fault is capable of generating a maximum
8 credible 7.5 magnitude earthquake. Because of the City's
urbanization and close proximity to a major fault, the
9 risk of a potential hazardous materials spill is
considerable.
10
2. Major earthquakes are always accompanied by disruption of
11 traffic flow and fires. During a major earthquake, fire
department resources would be extremely taxed, and the
12 ability to respond to fires and spills of hazardous
materials would be complicated and in some cases
13 impossible.
14 Topoqraphical Conditions:
15 1. The City has an urban atmosphere which is reflected in
building and building complex design and features.
16 Landscaping and other building features often preclude or
greatly limit approach or operational access by fire
17 department vehicles. With the dense urban areas close
together, the chance of a spill or spread of hazardous
18 materials is a considerable threat.
19 J. UFC Article 90 Standards, UFC Standard 52-1, Section
9002.2 is amended and is consistent with the 1995 Uniform
20 Fire Code Supplement and provides for residential fueling
of compressed natural gas vehicles.
21
These amendments are reasonably necessary because of the
22 following conditions:
23 Geoloqical Conditions:
24 1. The City is located in an area of high seismic activity.
The Newport-Inglewood Fault is close to the City, poses
25 the greatest hazard to life and property. It is believed
that this fault is capable of generating a maximum
26 credible 7.5 magnitude earthquake. Because of the degree
of the City's urbanization and close proximity to a major
27 fault, the risk of a potential leak of compressed natural
28 8
1 gas at various locations throughout the City is
considerable.
2
2. Major earthquakes are always accompanied by disruption of
3 traffic flow and fires. During a major earthquake, fire
department resources would be extremely taxed, and the
4 ability to respond to fires and leaks as a result of
compressed natural gas would be complicated and in some
5 cases impossible.
6 Topoqraphical Conditions:
7 1. The City has an urban atmosphere which is reflected in
building and building complex design and features.
8 Landscaping and other building features often preclude or
greatly limit approach or operational access by fire
9 department' vehicles. With the dense urban areas, the
chance. of a leak and ensuing fire from compressed natural
10 gas is considerable after a major earthquake. Density of
residential occupancies increased the threat if a leak or
11 fire occurs.
12 K. Appendix I-B Life-safety Requirements for Existing High
Rise Buildings, is amended to clarify that the Appendix
13 section applies only to buildings 75 feet tall or taller
and establishes specific requirements for a secondary
14 water source for the required fire sprinkler system.
15 These amendments are reasonably necessary because of the
following conditions:
16
Climatic Conditions:
17
1. The City of Tustin is located in semi-arid Mediterranean
18 type climate. It annually experiences extended periods
of high temperatures with little or no precipitation.
19 Hot, dry foehn (Santa And) winds, which may reach speeds
of 70 m.p.h., or greater, are also common to the area.
20 These climatic conditions cause extreme drying of
vegetation and common building materials and predispose
21 the area to large destructive fires (conflagration).
22 2. The climate alternates between extended periods of
drought and brief flooding conditions. Water demand in
23 this densely populated area far exceeds the quantity
supplied by natural precipitation; and although the
24 population continues to grow, the already taxed water
supply does not. California is projected to increase in
25 population by nearly l0 million over the next quarter of
a century of that 50 percent of that growth centered in
26 southern California.
27
28 9
1 3. These dry climatic conditions and winds contribute to the
rapid spread of even small fires originating in high
2 density housing or vegetation. These fires spread very
quickly and create a need for increased levels of fire
3 protection. The added protection of fire sprinkler
systems will supplement normal fire department response
4 by providing immediate protection for the building
occupants and by containing and controlling the fire
5 spread to the area of origin. Fire sprinkler systems
will also reduce the use of water for fire fighting by as
6 much as 50 to 75 percent.
7 Topographical Conditions:
8 1. Traffic and circulation congestion is an artificially
created~ obstructive topographical condition, which is
9 common in the City of Tustin and throughout Orange
County.
10
2. These topographical conditions combine to create a
11 situation which places fire department response time to
fire occurrences at risk, and makes it necessary to
12 provide automatic on-site fire extinguishing systems to

a maximum credible 7.5 magnitude earthquake. Because of
17 the degree of City's urbanization and close proximity to
a major fault, the risk of structural damage and loss of
18 'life due to ground shaking is considerable.
19 2. Major earthquakes are always accomplished by disruption
of traffic flow and fires. During a major earthquake,
20 fire department resources would be extremely taxed, and
the ability.to respond to fires would be complicated and
21 in some cases impossible. On-site fire extinguishing
systems would provide a degree of protection from fires
22 even if water mains are damaged or destroyed.
23 L. Appendix V, Adopted Standards Section Z

Sprinklers.
3. NFPA 13R, 1994 Edition, Standards for the
3 Installation of Sprinkler Systems in Residential
Occupancies up to Four Stories in Height is amended
4 to cover areas where sprinklers may be omitted.
5 These amendments are reasonably necessary because of the
following conditions:
6
7 Climatic Conditions:
8 1. The City of Tustin is located in a semi-arid
Mediterranean type climate. It annually experiences
9 extended periods of high temperatures with little or no

25 created,..obstructive topographical condition which is
common in the City of Tustin and throughout Orange
26 County.
27
28 11
1 2. These topographical conditions combine to create a
situation which places fire department response time to
2 fire occurrences at risk, and makes it necessary to
provide automatic on-site fire extinguishing systems to
3 protect occupants and property.
4 Geoloqical Conditions:
5 1. The City is located in an area of high seismic activity.
The Newport-Inglewood Fault, located west of the City,

some cases impossible. On-site fire extinguishing
12 systems would provide a degree of protection from fires
even if water mains are damaged or destroyed.
13
M. NFPA 14, 1993 Edition, Standard for the Installation of
14 Standpipe and Hose Systems is amended to cover Fire
Department Connections, and Minimum Pressure for System
15 Design and Sizing of Pipe.
16 These amendments are reasonably necessary because of the
following conditions:
17
Climatic Conditions:
18
1. The City of Tustin is located in a semi-arid
19 Mediterranean type climate. It annually experiences
extended periods of high temperatures with little or no
20 precipitation. Hot, dry foehn (Santa Aria) winds, which
may reach speeds up to 70 m.p.h., are also common to the
21 area. These climatic conditions cause extreme drying of
vegetation.and common building materials and predispose
22 the area to large destructive fires (conflagration).
23 2. The climate alternates between extended periods of
drought and brief flooding conditions. Water demand in
24 this densely populated area far exceeds the quantity

11 situation which places Ifire department response time to
fire occurrences at risk, and makes it necessary to
12 provide automatic on-site fire extinguishing systems to
protect occupants and property.
13
3. The increased pressure is necessary for the system to
14 function utilizing the standard Orange County Fire
Authority equipment. It is also necessary to compensate
15 for the design factors which created the inadequate
standpipe system design at the fatal fire in
16 Philadelphia, Pennsylvania on February 23, 1991. The
amendments address the issues which were brought forth in
17 this fire. They are consistent with the Los Angeles City
and County Fire Departments' requirements and reflect
18 changes which are proposed to the national standard for
standpipe design, NFPA 14.
19
Geoloqical Conditions:
20
1. The City is located in an area of high seismic activity.
21 The Newport-Inglewood Fault, located n'orthwest of the
City, poses the greatest hazard to life and property. It
22 is believed that this fault is capable of generating a
maximum credible 7.5 magnitude earthquake. Because of
23 the City's degree of urbanization and close proximity to

26 department resources would be extremely taxed, and the
ability to respond to fires would be complicated and in
27 some cases impossible. On-site fire extinguishing
28 13
1 systems would provide a degree of protection from fires
even if water mains are damaged or destroyed.
2
N. NFPA 24, 1992 Edition, Standard for Private Fire Service
3 Mains and their Appurtenances is amended to cover
Installation Work, Public Water Systems, Fire Department
4 Connections, Post Indicator Valves, Valves in Pits,
Sectional Valves, Coating and Lining of Pipe, Pipe Joint
5 Assembly, and Testing Underground Systems.
6 These amendments are reasonably necessary because of the
following conditions:

1. The City of Tustin is located in a semi-arid
9 Mediterranean type climate. It annually experiences
extended periods of high temperatures with little or no
10 precipitation. Hot, dry foehn (Santa Ana) winds, which
may reach speeds up to 70 m.p.h., are also common to the

23 will also reduce the use of water for fire fighting by as
much as 50 to 70 percent. This is the only method of
24 water conservation available for fire fighting
activities.

Topoqraphical Conditions:
26
1. Traffic and circulation congestion is an artificially
27 created, obstructive topographical condition which is
28 14
1 common in the City of Tustin and throughout Orange
County.
2
2. These top0graphical conditions combine to create a
3 situation which places fire department response time to
fire occurrences at risk, and makes it necessary to
4 provide automatic on-site fire extinguishing systems to
protect occupants and property.
5
Geoloqical Conditions:
6
1. The City is located in an area of high seismic activity.
7 The Newport-Inglewood Fault, located west of the. City,
poses the greatest hazard to life and property. It is
8 believed that this fault is capable of generating a
maximum credible 7.5 magnitude earthquake. Because of
9 the City's degree of urbanization and close proximity to
a major fault, the risk of structural damage and loss of
10 life due to ground shaking is considerable. This threat
is compounded by the City's location of the Norwalk
11 Fault.
12 2. Major earthquakes are always accompanied by disruption of
traffic flow and fires. During a majorearthquake, fire
13 department resources would be extremely taxed, and the
ability to respond to fires would~be complicated and in
14 some cases impossible. On-site fire extinguishing
systems would provide a degree of protection from fires
15 even if water mains are damaged or destroyed.
16 3. Soil conditions throughout the Orange County area and the
City are extremely corrosive and have an adverse effect
17 -- on underground fire sprinkler system piping, joints and
.... valves.
