WHEREAS, the Community Development Department and
Orange County Fire Services have recommended that changes
and modifications be made to the Codes and have advised
that certain said changes and modifications to the
Uniform Fire Code, 1991 Edition, are reasonably necessary
due to local conditions in the City and have further
advised that the remainder of said changes and
modifications are of an administrative or procedural
nature, or concern themselves with subjects not covered
by the Codes or are reasonably necessary to safeguard
life and property %~ithin the City.
NOW, THEREFORE, BE IT RESOLVED by the City Council
of the City of Tustin as follows:
SECTION 1. The following changes and modifications
to the 1991 Uniform Fire Code, as recommended by the city
building official, are hereby found to be reasonably
necessary due to the following local conditions.
A. UFC Section 10.507 (modifies corresponding Title
24, California Code of Regulations, Section 3802) has
been amended to require that all buildings with a gross
square footage of 6,000 or greater or more than two
stories in height; and all new Group R, Division 1 and
Group R, Division 3 buildings other than detached one and
two family dwellings have an approved automatic fire
sprinkler system in addition to the other requirements of
the Uniform Building Code.
Additionally, all new R-3 occupancies, de~ached one and
two family dwellings, where the gross square footage of
the building exceeds 6,000 square feet or more than two
stories in height, shall be equipped with an automatic
sprinkler system. Residential cr quick response standard
sprinkler heads shall be used in the dwelling unit and
guest room portions cf the building.
Climatic conditions:
i. The City is located in a semi-arid
Mediterranean type climate.
It annually experiences extended periods of
high temperatures wi~h little or no
precipitation. Hot dry foehn (Santa Ana
wind), which may reach speeds up to 70 m.p.h,
is also common to the City. These climatic
condi=ions cause extreme drying of vegetation
and common building materials and predispose
the area ~o large destructive fires
(conflagration).

The climate alternates between extended
periods of drought and brief flooding
conditions. Water demand in this densely
populated area far exceeds the quantity
supplied by natural precipitation; and
although the population continues to grow the
already taxed water supply does not.
California is projected to increase in
population by nearly 10 million over the next
quarter of a century with 50 percent of that
growth centered in Southern California.
These dry climatic conditions and winds
contribute to the rapid spread of even small
fires originating in high density housing or
vegetation. These fires spread very quickly
and create a need for increased levels of fire
protection. The added protection of fire
sprinkler systems will supplement normal fire
department response, by providing immediate
protection for the building occupants and by
containing and controlling the fire spread to
the area of origin. Fire sprinkler system
will also reduce the use of water for
firefighting by as much as 50 to 75 percent.
Topographical conditions:
Traffic and circulation congestion is an
artificially created, obstructive
topographical condition, which is common in
the City.
These topographical conditions combine to
create a situation which places fire
department response time to fire occurrences
at risk, and makes it necessary to provide
automatic on-site fire-e×tinguishing systems
for reasonable protection of occupants, guests
and property.
Geological conditions:
The City is located in an area cf high seismic
activity, seismic zone 4. The Newport-
Inglewood Fault, located west of the City,
poses the greatest hazard to life and
property.

Geologic studies indicate that this fault is
capable of generating a maximum credible 7.5
magnitude earthquake. Because of the City's
degree of urbanization and close proximity to
a major fault, the risk of structural damage
and loss of life due to ground shaking is
considerable.
Major earthquakes are always accompanied by
disruption of traffic flow and fires.
During a major earthquake fire department
resources would be extremely taxed and the
ability to respond to fires would be
complicated and in some cases impossible due
to disrupted traffic flow in what is already a
congested area. On-site fire-extinguishing
systems would provide a heightened degree of
protection from fires even if water mains are
damaged or destroyed.
B. Section 10.510 (b) (modifies corresponding Title
24, California Code of Regulations, Section 3805) has
been amended to require fire department access to, or
additional standpipe outlets for, any building with a
horizontal dimension of 300 feet or greater. This is
compatible with fire fighting equipment and human
resources available to the local fire department.
TopoqraDhica! conditions:
Traffic and circulation congestion is an
artificially created , obstructive
topographical condition, which is common in
the City.
Many large commercial/industrial buildings
exist in the City, which have a horizontal
dimension of 300 feet or greater, creating an
unusual topographical condition. Portions of
these buildings cannot be reached with a fire
hose line on initial attack.
These topograpkica! conditions combine to
create a situation which hinders fire
department response time to fire occurrences
and makes it necessary to provide additional
on-site fire fighting resources.

C. Section 10.514 (modifies corresponding Title 24,
California Code of Regulations, Section 1807) has been
amended to define high-rise buildings as any structure 55
feet or greater in height above the lowest level of fire
department vehicle access.
This section also requires a roof top emergenc~ access
and evacuation facility on all buildings 75 feet or
greater in height with an occupancy classification of
Group B, Division 2 or Group R, Division 1. Optional
provisions are provided for buildings with a roof slope
greater than 4 in 12.
ToDoqraphJcal conditions:
The City has an urban atmosphere which is
reflected in building and building complex
design and features. Landscaping and other
building features often preclude or greatly
limit approach or operational access by fire
department vehicles. The UBC high-rise
provisions were developed to provide for fire
department laddering capabilities and response
time in a downtown Los Angeles or New York
City setting. These older cities typically
have high-rise buildings which are constructed
close to the street, but in the City kigh-rise
buildings typically have side yards and
landscaping.
D. Section 11.505 (modifies corresponding Title 24,
California Code of Regulations, Section 3703) has been
amended to require chimney spark arresters on all new
devices that burn any solid or liquid fuel. This
protection is needed because of the area climatic
conditions.
Climatic conditions:
The City is located in a semi-arid
Mediterranean type climate. It annually
experiences e×tended periods of high
~emperatures with little or no precipitation,
which causes extreme drying of vegetation and
common building materials.
o
The City is also subject to extreme foehn
(Santa Ana wind) conditions which further
contributes to drying and rapid spread of
~ire

These climatic conditions combine to create a
unique situation where vegetation and building
materials are the driest during the fall
months. Fireplaces are most frequently used
during this time and flying embers become a
hazard for building materials or vegetation in
the City.
E. Appendix V Adopted Standards, Section 5. NFPA 14
Standard for the installation of Standpipe and Hose
Systems, 1990 Edition (modifies corresponding Title 24,
California Code of Regulations, Section 6003 (c) 8.) has
been amended to provide for a system test/drain pipe and
increase system pressure.
ToDograDhica! condStions:
The test/drain valve will allow state-mandated
functional flow testing of the system. The
increased pressure is necessary for the system
to function utilizing the standard Orange
County Fire Department equipment. It is also
necessary to compensate for the design factors
which created the inadequate standpipe system
design at the fatal fire in Philadelphia,
Pennsylvania, on February 23, 1991. The
amendments address the deficiencies which were
revealed by this fire. They are consistent
with the Los Angeles City and County Fire
Departments requirements and reflect changes
which are propcsed to the national standard
for standpipe design, NFPA 14.
PASSED AND ADOPTED at a regular meeting of the Tustin
City Council, held on the 21st day of June, 1993.
