of the 2022 Edition of the California Electrical Code as recommended by the Public Works
Department are hereby found to be reasonably necessary due to the following local conditions:
Section 1:
A. Climatic Conditions
1. Hot, dry Santa Ana winds are common to all areas within the City of Orange and Orange
County in general. These winds, which can cause small fires that 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 available and provide immediate protection for life and safety of multiple
occupancy occupants during fire occurrences.
2. Orange County and the City of Orange are 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.
3. The warm, dry climate is conducive to swimming pools,which creates a higher probability
of child drownings where pools are unprotected.
B. Geographic Conditions
1. Orange County and the City of Orange 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, 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 our 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."
Resolution No. 11416 2
2. Traffic and circulation congestion presently existing in the City of Orange 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.
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.
