FINDINGS
I. Climatic Conditions
187
A. The jurisdiction of Cypress is located in a semi -arid Mediterranean type
climate. It annually experiences extended periods of high temperatures with
little or no precipitation. Hot, dry (Santa Ana) winds, which may reach speeds
of 70 m.p.h. or greater are also common to the area. These climatic conditions
cause extreme drying of vegetation and common building materials. Frequent
periods of drought and low humidity add to the fire danger. This predisposes
the area to large destructive fires (conflagration). In addition to directly
damaging or destroying buildings, these fires also disrupt utility services
throughout the area.
(For High Rise Only) Obstacles generated by strong winds, such as fallen
trees, street lights and utility poles, and the requirement to climb 75 feet
vertically up flights of stairs will greatly impact the response time to reach an
incident scene. Additionally, there is a significant increase in the amount of
wind force at 60 feet above the ground. Use of aerial type fire fighting
apparatus above this height would place rescue personnel at increased risk of
injury.
B. The climate alternates between extended periods of drought and brief flooding
conditions. Flood conditions may affect the Orange County Fire Authority's
ability to respond to a fire or emergency condition. Floods also disrupt utility
services to buildings and facilities within the County.
C. 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. Due to storage
capacities and consumption and a limited amount of rainfall, future water
allocation is not fully dependable. This necessitates the need for additional on-
site fire protection features. The shortage of water would also leave tall
buildings vulnerable to uncontrolled fires due to a lack of available water and
an inability to pump sufficient quantities of available water to upper floors in a
fire.
D. 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 and other fire protection features
will supplement normal fire department response by providing immediate
protection for the building occupants and by containing and controlling the fire
6
188
spread to the area of origin. Fire sprinkler systems will also reduce the use of
water for firefighting by as much as 50 to 75 percent.
II. Topographical conditions:
A. Natural slopes of 15 percent or greater generally occur throughout the foothills
of Orange County. The elevation change caused by the hills creates the
geological foundation on which communities within Orange County are built
and will continue to build. With much of the populated flatlands already built
upon, future growth will occur on steeper slopes and greater constraints in
terrain.
B. Traffic and circulation congestion is an artificially created, obstructive
topographical condition, which is common throughout Orange County.
C. 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 - extinguishing systems and other protection
measures to protect occupants and property.
III. Geological conditions:
The Orange County region is a densely populated area that has buildings constructed over
and near a vast and complex network of faults that are believed to be capable of
producing future earthquakes similar or greater in size than the 1994 Northridge and the
1971 Sylmar earthquakes. Earthquake faults run along the northeast and southwest
boundaries of Orange County. The Newport- Inglewood Fault, located within Orange
County was the source of the destructive 1933 Long Beach earthquake (6.3 magnitude)
which took 120 lives and damaged buildings in an area that ran from Laguna Beach to
Marina del Rey to Whittier. In December 1989, another earthquake occurred in the
Irvine at an unknown fault line. Regional planning for reoccurrence of earthquakes is
recommended by the State of California, Department of Conservation.
A. Previous earthquakes have been accompanied by disruption of traffic flow and
fires. A severe seismic event has the potential to negatively impact any rescue
or fire suppression activities because it is likely to create obstacles similar to
those indicated under the high wind section above. With the probability of
strong aftershocks there exists a need to provide increased protection for
anyone on upper floors of buildings. The October 17, 1989, Santa Cruz
earthquake resulted in one major fire in the Marina District (San Francisco).
When combined with the 34 other fires locally and over 500 responses, the
department was taxed to its fullest capabilities. The Marina fire was difficult
to contain because mains supplying water to the district burst during the
earthquake. This situation creates the need for both additional fire protection
and automatic on -site fire protection for building occupants. The State
Department of Conservation noted, in their 1988 report (Planning Scenario on
a Major Earthquake on the Newport Inglewood Fault Zone, page 59),
7
189
"unfortunately, barely meeting the minimum earthquake standards of building
codes places a building on the verge of being legally unsafe."
B. Road circulation features located throughout the County also make
amendments reasonably necessary. There are major roadways, highways and
flood control channels that create barriers and slow response times. Hills,
slopes, street and storm drain design accompanied by occasional heavy
rainfall, causes roadway flooding and landslides and at times may make an
emergency access route impassable. There are areas in Orange County that
naturally have extended emergency response times that exceed the 5 minute
goal.
C. Soils throughout the County posses corrosive properties that reduce the
expected usable life of water services when metallic pipes come in contact
with these soils.
Due to the topographical conditions of sprawling development separated by waterways
and narrow and congested streets and the expected infrastructure damage inherent in
seismic zone described above, it is prudent to rely on automatic fire sprinkler systems to
mitigate extended fire department response time and keep fires manageable with reduced
fire flow (water) requirements for a given structure. Additional fire protection is also
justified to match the current resources of firefighting equipment and personnel within
the Orange County Fire Authority.
