Resolution No. 2022-63 Page 1 of 5
WHEREAS, amendments related to life and fire safety contained in Table 1505.1,
Sections 1505.1.2 & 1807.1.6, and section 105.2 of the 2022 Edition of the California
Building Code, and Table R301.2, Sections R902.1, R902.1.3, R902.2 of the 2022 Edition
of the California Residential Code, Sections 503.2, 901.11. Chapters 1, 3, 4, 5, 9, 12, 25,
26, 31, 56, 57, 58, & 80 of the 2022 California Fire Code as recommended by the
Development Services Department are hereby found to be reasonably necessary due to
the following local conditions:
A. Climatic Conditions
1. Hot, dry Santa Ana winds are common to all areas within the City of Costa Mesa
and Orange County in general. These winds, which can cause small fires which spread
quickly, are a contributing factor to the high fire danger in the area and create the need
for an increased level of fire protection. This added protection will supplement normal Fire
Department response and provide protection for life and safety of multiple occupants
during fires.
2. Orange County and the City of Costa Mesa are in a semi -arid Mediterranean
type of climate which predisposes all fuels, including wood shingles, to the rapid ignition
and spread of fire. Therefore, there exists a need for additional fire protection measures.
B. Geographic Conditions
1. Orange County and the City of Costa Mesa are in a high seismically active area.
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. The NIFZ currently
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 upon which this quake occurred was unknown prior to this activity.
The October 17, 1989 Loma Prieta 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 required, the local Fire department was taxed to its full capabilities. The
Resolution No. 2022-63 Page 2 of 5
Marina fire was difficult to contain because water 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 the Orange County area within 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";
2. Peak hour traffic and circulation congestion in the City of Costa Mesa contribute
to potential response delays in the Fire & Rescue Department's travel time to fire and
rescue emergency occurrences. This condition will be exacerbated by any major
emergency, including a natural or manmade disaster, wherein damage to the City's critical
infrastructure or the highway system's under and overpasses may create impenetrable
barriers. Additionally, responding to existing outlying areas and future development sites
will likely be delayed. This condition makes the need for additional on -site protection of
property and occupants necessary.
3. 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. Past Grand Jury Report findings support this concern.
