Section 1 The following changes and
modifications to the 1988 Edition of the Uniform
Building Code as recommended by the Community
Development Department and Orange County Fire Services
are hereby found to be reasonably necessary due to the
following local conditions.
A. Section 1807 and 3310 is amended to make fire
access requirements applicable to high rise structures,
with specified exceptions, over 55 feet in height,
rather than the 75 feet threshold of the Uniform
Building Code. This modification was originally
recommended by the Orange County Fire Chiefs Association
and adopted by many jurisdictions in the County. The
amendment was also adopted by Las Vegas after the MGM
Grand Hotel fire. Other modifications to Section 1807
are to conform to minimum standards for high rise
buildings set forth in Title 24 of the California Code
of Regulations.
Climatic Conditioq: Hot, dry Santa Ama
winds are common to all areas within the
City of Tustin and Orange County. These
winds area constitute a contributing
factor which can cause small fires which
spreads quickly, and creates the need for
an increased level of fire protection.
This added protection will supplement
normal fire department response available
in high density occupancies, and provide
immediate protection for life and safety
of multiple occupancy occupants during
fire occurrences.
Climatic Condition: Orange Ccunty and
the city of Tustin is located in a semi-
arid Mediterranean type climate which
predisposes all fuels, including wood

shingles to rapid ignition and spread of
fire. Therefore, there exists a need for
additional fire protection measures;
GeoGraphic Condition: Orange County and
the City of Tustin are located in Seismic
Zone 4. There are earthquake faults that
run along both the northeastern and
southwestern boundaries of Orange County.
The Newport-Inglewood Fault Zone (NIFZ)
which runs through Orange County was the
source of the destructive 1933 Long Beach
earthquake (6.3 magnitude, hypocenter off
Newport Beach coast) , which took 120
lives, with areas damaged from Laguna
Beach to Marina del Rey and inland to
Whittier, and poses one of the greatest
hazards to lives and property in the
nation. Regional planning for
reoccurrence is recommended by the State
of California, Department of
Conservation. There was also an
earthquake in December, 1989, with the
epicenter located near the City of
Irvine. The fault on which this quake
occurred was unknown prior to this
activity. The October 17, 1989 Santa
Cruz earthquake resulted in only one
major San Francisco fire in the Marina
district, but when combined with the 34
other fires and over 500 responses, the
department was taxed to its full
capabilities. The Marina fire was
difficult to contain because mains
supplying water to the district burst
during the earthquake. If more fires had
been ignited by the earthquake, it would
have been difficult for the fire
department to contain them. Experts
predict a major earthquake in cur area
with the next 50 years. This situation
creates the need for both additional fire
protection measures and automatic on-
site fire protection for building
occupants since a multitude of fires may
result from breakage of gas and electric

lines as a result of an earthquake. As
noted by "Planning Scenario on a Major
Earthquake on the Newport-Inglewood Fault
Zone, 1988, State Department of
Conservation," page 59, "unfortunately,
barely meeting the minimum earthquake
standards of building codes places a
building on the verge of being legally
unsafe";
GeograDhv and To~oqraphy: Traffic and
circulation congestion presently existing
in the City of Tustin often places fire
department response time to fire
occurrences at risk. This condition will
be exacerbated by any major disaster,
including any earthquake wherein damage
to the highway system will occur. This
condition makes the need for additional
on-site protection for property occupants
necessary.
Geography and ToDoqr~phy: Placement of
multiple occupancy buildings, location of
arterial roads, and fire department
staffing constraints due to recent
revenue limiting state legislation have
made it difficult for the fire department
to locate additional fire stations and
provide manpower sufficient to
concentrate fire companies and personnel
to control fires in high density
apartment or condominium buildings.
Orange County Fire Department equipment
does not allow easy access to areas of
buildings greater than 55 feet above the
level of Fire Department vehicle access.
These conditions create the need for
built-in on-site fire protection systems
to protect occupants and property until
fire fighting apparatus and personnel
arrive on the scene, as otherwise
required for high rises.

Other public and safety concerns:
a. Smoke proof stairwell enclosures.
The stairwells in the 1980 MGM Grand
Hotel fire in Las Vegas (deathtoll 88,
600 injured) and the Dupont Hotel fire
were filled with smoke which trapped the
occupants in the buildings. The
stairwell enclosures in the First
Interstate Bank fire in Los Angeles were
filled with smoke which required the
firefighters to use their airpacks as
they climbed the stairs to locate and
attack the fire. It is not possible for
the firefighters to carry enough air
bottles for their airpacks to even reach
a fire on a floor above approximately the
sixth floor, let alone be able to work on
the fire after it is located.
An emergency evacuation facility on the
roof of high rise is currently required
in the City of Long Beach and many other
larger jurisdictions. Statistics show
that many people evacuate to the roof
area of a high rise building in the event
of a fire, especially if they are on a
floor above the fire. Obstructions on
the roof can block aerial access to the
roof for evacuation or delivering
firefighting personnel and equipment.
The Mexico City earthquake demonstrated
that a high rise building located in an
area subject to liquefaction may actually
sink into the ground which will block all
of the normal egress into the building.
This, along with the possibility of
roadway damage, gridlock, and/or falling
debris, would make aerial access to the
roof area an essential operation for
firefighting and rescue operations. This
has been demonstrated in many high rise
fires such as the MGM Grand Hotel fire
(30 helicopters use~ within first hour;
300-400 victims rescued), the First
Interstate Bank fire (29.5 hours flown),

the Dupont Hotel fire in Puerto Rico and
a nine-story high rise fire in Los
Angeles on December 5, 1989.
B. Section 3203 is amended to requi~e roof
coverings on residential (R) and (M) accessory buildings
occupancies to be of a fire resistant material of a
Class C or better except in hillside areas where Class
A roof coverings shall be used due to:
Prevailing Santa Ana winds occurring in
the local region as more specifically
described in subsection A.1 above and
incorporated herein.
Untreated wood roofs cause or contribute
to serious fire hazard and to the rapid
spread of fires when such fires are
accompanied by high winds. Pieces of
burning wooden roofs become flying brands
and are carried by the wind to other
locations and thereby spread fire
quickly.
Semi-arid climatic conditions more
specifically described in subsection A.2
and incorporated herein.
Local geography and topography as more
specifically described in subsections
A.3, A.4 and A.5 and incorporated herein.
C. Section 3703 (f) is amended to require spark
arrestors on chimneys and are necessary due to all
climatic conditions described in subsections A.1 and A.2
and incorporated herein.
D. Section 3802 is amended relating to automatic
fire extinguishing systems in new buildings with an area
greater than 6,000 square feet or more than two stories
in height and to require an approved automatic fire
sprinkler system for certain residential occupancies for
the following reasons:
Amendments are necessary due to general

subsection A.1, A.2, A.3, A.4, and A.5
and incorporated herein.
On-site residential protection systems
will effectively reduce fire fatalities,
injuries and property loss during Orange
County's and the City of Tustin's unique
local geographical, climatic and
topographical conditions because they are
96% effective in prevention of fatalities
and reduce fire loss to less than $5,000
with two or less sprinkler heads.
Residential fires represent 75% of
building fires in California , all
fatalities from fires in Orange County
fire service jurisdictions occurred in
residences.
E. Section 3805(6) is amended and relates to
standpipes and requires a hose outlet or access doorway
within 150 feet of all parts of ccmmercial buildings so
that a sprinkler system can be shut off earlier
resulting in less water damage. This amendment is
necessary due to all general findings specifically
described in subsection A.1, A.2, A.3, A.4 and Ao5 and
incorporated herein.
Section 2 The following changes and
modifications to the 1988 Edition of the Uniform
Plumbing Code as recommended by the Community
Development Department are hereby found to be reasonably
necessary due to the following local conditions for
housing.
A. Section 315 (g) has been added to state that
the type of soil prevalent in the City of Tustin is
extraordinarily high in sulfur and acid content. That
extra precaution and protection is required for the
protection of steel piping and fittings buried in the
ground.
B. Section 1004 has been amended to prohibit the
use of lead and asbestos cement materials in all potable
water supply systems.

C. Section 1008 has been amended to reflect
certain natural constituents in the water which are
corrosive to ferrous piping.
D. Section 12].2 and 1213 has been amended to
reflect certain natural constituents in local soils
which are corrosive to gas piping.
Section 3 The following changes and modifications
to the 1990 edition of the National Electrical Code as
recommended by the Community Development Department are
hereby found to be reasonably necessary due to the
following local conditions for housing.
A. Article 110-5 is amended by making copper wire
the preferred material used for wiring No. 6 and
smaller. This amendment is considered necessary due to
the fact that improper installation creates a potential
fire hazard and aluminum wire size No. 6 an~ smaller
requires greater precision and care for proper
installation. Workmanship problems have been
experienced in the local area, which makes this
provision necessary. The regulation of aluminum wire is
reasonably necessary to safeguard life and property
within the City of Tustin.
B. Article 300-6 is amended to state that the
type of soil prevalent in the city of Tustin necessitate
additional precaution and protection for buried
installation of electrical items.
C. Amendments to Article 310-10 are considered
necessary due to the fact that improper installation
creates a potential fire hazard and aluminum wire size
No. 6 and smaller require greater precision and care for
proper installation.
D. Article 336-3 is amended to safeguard life and
property within the City of Tustin particularly given
prevailing fire hazard conditions in the City.
Section 4 Additional amendments have been made
to the Uniform Building Code, 1988 Edition, the Uniform
Plumbing Code, 1988 Edition, Uniform Mechanical Code,
1988 Edition, and the National Electrical Code, 1988
Edition. On the recommendation of the Community
