State law requires all counties and cities to adopt and enforce the same regulations that are adopted by the state. State law also allows local jurisdictions to make modifications and changes to the state-adopted codes, provided these amendments are reasonably necessary because of climatic,geographical, or topographical conditions, or are administrative revisions to the state codes. The attached ordinance adopts the California Electrical Code with modifications and changes that are reasonably necessary because of the County's unique climatic, geographical and topographical conditions. The attached findings describe the conditions that make the modifications and changes to the California Electrical Code reasonably necessary. The 2004 California Electrical Code is largely unchanged from the 2001 California Electrical Code, which was previously adopted by the County and is currently in effect in the County. However,the 2004 California Electrical Code establishes new requirements to protect against arc faulting in bedrooms and new requirements for ground fault interceptors in commercial buildings. The 2004 California Electrical Code also renumbers several sections. The attached ordinance incorporates these changes into the County Ordinance Code, and also establishes the local requirement that all occupancies with commercially supplied electricity connect to the commercial supplier and not use a permanent or temporary generator. Staff has determined that adoption of the attached ordinance is exempt from the California. Environmental Quality Act (CEQA) under section 15061(b)(3) of the CEQA Guidelines. Staff has determined that it can be seen with certainty that adoption of the ordinance will not have a significant effect on the environment. CONSEQUENCES OF NEGATIVE ACTION The goal of staff has been to develop one up-dated ordinance that integrates the prior County administrative sections and modifications in Title 7 with the requirements of the California Electrical Code. If action is not taken to have one integrated ordinance, inconsistencies between the county's provisions and the California Electrical Code will remain. This may lead to different staff interpretations and general confusion by the public. CB:nr /bdord/oec9-13-05 CONTRA COSTA COUNTY FINDINGS JUSTIFYING CHANGES DUE TO LOCAL CONDITIONS I. Changes or Modifications Pursuant to California Health and Safety Code section 17958 the Board of Supervisors of Contra Costa County, in its ordinance adopting the 2004 California Electrical Code, changes, modifies, and amends provisions of the California Electrical Code regarding fire- protection systems, and other related provisions. 110 Finding Pursuant to Health and Safety Code sections 17958.5 and 17958.7, the Board of Supervisors of Contra Costa County finds that changes, modifications, and amendments to the California Electrical Code are needed and are reasonably necessary because of certain I*,* local climatic, geological, and topographic conditions as described below. A. Geological and Topographic 1, Seismicity (a) Conditions Contra Costa. County is located in Seismic Risk Zone 4, which is the worst earthquake area in the United States. Buildings and other structures in Zone 4 can experience major seismic damage. Contra Costa County is in close proximity to numerous earthquake faults including the San Andreas Fault and contains all or portions of the Hayward, Calaveras, Concord, Antioch, Mt. Diablo, and other lesser faults. A 4.1 earthquake with its epicenter in Concord occurred in 1958,, and a 5.4 earthquake with its epicenter also in Concord occurred in 1955. The Concord and Antioch faults have a potential for a Richter 6 earthquake and the Hayward and Calaveras faults have the potential for a Richter 7 earthquake. Minor tremblers from seismic activity are not uncommon in the area. A study released in 1990 by the United States Geological Survey says 10 that there is a 67% chance of another earthquake the size of Loma Prieta during the next 30 years, and that the quake could strike at any time, including today. Scientists, therefore, believe that an earthquake of a magnitude 7 or larger is now twice as likely to happen as to not happen. t Interstates 680, 80, 580 and State Route 4 run the length throughout Contra Costa County. These interstates and state routes divide the, County into a west, south, ., north and east. An overpass or undercrossing collapse would significantly alter the response route and time for responding emergency equipment. This is due to limited crossings of the interstate and that in some areas there is only one surface street, which runs parallel to the interstate, which would be congested during a significant emergency. Earthquakes of the magnitude experienced locally can cause major damage to electrical transmission facilities and to gas and electrical lines in buildings, which in turn start fires throughout the County. The occurrence of multiple fires will quickly deplete existing fire department resources; thereby reducing and/or delaying their response to any given fire. (b) Impact A major earthquake could severely restrict the response of all Contra Costa County Fire Districts and their capability to control fires involving buildings of wood frame construction, with ordinary roofing materials and flammable exteriors, or with large interior areas not provided with automatic smoke and fire control systems. Also, when buildings not equipped with earthquake structural support move off their foundations, gas pipes may rupture. Fires develop from line ruptures and spread from house to house, causing an extreme demand for fire protection resources. 2, Soils (a) Conditions The area is replete with various soils, which are unstable, clay loam and alluvial fans being predominant. These soil conditions are moderately to severely prone to swelling and shrinking, are plastic, and tend to liquefy. Throughout Contra Costa County, the topography and development growth has created a network of older, narrow roads. These roads vary from gravel to asphalt surface and vary in percent of slope, many exceeding twenty (20) percent. Several of these roads extend up through the winding passageways in the hills providing access to remote, affluent housing subdivisions. The majority of these roads are private with no established maintenance program. During inclement weather, these roads are subject to rock and mudslides, as Contra Costa County Findings 2 2004 California Electrical Code well as down trees, obstructing all vehicle traffic. It is anticipated that during an earthquake, several of these roads would be unpassable so as to prevent fire protection resources from reaching fires cause by gas line ruptures or other sources. 3. TopogLaphic (a) Conditions i. Vegetation Highly combustible dry grass, weeds, and brush are common in the hilly and open space areas adjacent to built-up locations six (6) to eight (8) months of each year. Many of these areas frequently experience wildland fires, which threaten nearby buildings, particularly those with wood roofs, or sidings. This condition can be found throughout Contra Costa. County, especially in those developed and developing areas of the County. Earthquake gas fires due to gas line ruptures can ignite grasslands and stress fire district resources. (b) Impact The above local geological and topographical conditions increase the magnitude, exposure, accessibility problems, and fire hazards presented to the County fire resources. Fire following an earthquake has the potential of causing greater loss of life and damage than the earthquake itself. Most earthquake fires are created by natural gas developed from gas line ruptures. Hazardous materials, particularly toxic gases, could pose the greatest threat to the largest number, should a significant seismic event occur. Public safety resources would have to be prioritized to mitigate the greatest threat, and may likely be unavailable for smaller single dwellings that were caused by broken gas lines. Other variables may tend to intensify the situation: I- The extent of damage to the water system 2. The extent of isolation due to bridge and/or freeway overpass collapse. 3. The extent of roadway damage and/or amount of debris blocking the roadways. 4. Climatic condition (hot, dry weather with high winds). 5. Time of day will influence the amount of traffic on roadways and could intensify the risk to life during normal business hours. Contra Costa County Findings 3 2004 California Electrical Code 6. The availability of timely mutual aid or military assistance. 7. The large portion of dwellings with wood shake or shingle coverings could result in conflagrations. 8. The large number of dwellings that slip off their foundations and rupture gas lines and electrical systems resulting in further conflagrations. B. Climatic I Precipitation and Relative Humidity (a) Conditions Precipitation ranges from 15 to 24 inches per year with an average of approximately 20 inches per year. Ninety-six (96)percent falls during the months of October through April and four (4) percent from May through September. This is a dry period of at least five (5) months each year. Additionally, the area is subject to occasional drought. Relative humidity remains in the middle range most of the time. It sixty-five (65) during spring, ranges from forty-five (45) to si .J summer!, fall,, and from sixty (60) to ninety (90) percent in the winter. It occasionally falls as low as fifteen (15)percent. (b) Impact Locally experienced dry periods cause extreme dryness of untreated wood shakes and shingles on buildings and non-irrigated grass, brush and weeds!, which are often near buildings with wood roofs and sidings. Such dryness causes these materials to ignite very readily and bum rapidly and intensely. Gas fires due to gas line ruptures can also spark and engulf a single family residence during these dry periods. Because of dryness, a rapidly burning gas fire or exterior building fire can quickly transfer to other buildings by means of radiation or flying 0 .2.2 brands,, sparks or embers. A small fire can rapidly grow to a magnitude beyond the control capabilities of the Fire District resulting in an excessive fire loss. 2. Temperature (a) Conditions Contra Costa County Findings 4 2004 California Electrical Code Temperatures have been recorded as high as 114°F. Average summer highs are in the 750 - 90' range, with average maximums of 105° Fin some areas of unincorporated Contra Costa County. (b) Impact High temperatures cause rapid fatigue and heat exhaustion of firefighters, thereby reducing their effectiveness and ability to control large building, wildland fires, and fires caused by gas line ruptures. Another impact from high temperatures is that combustible building material and non-irrigated weeds, grass and brush are preheated, thus causing these materials to ignite more readily and bum more rapidly and intensely. Additionally, the resultant higher temperature of the atmosphere surrounding the materials reduces the effectiveness of the water being applied to the burning materials. This requires that more water be applied, which in turn requires more fire resources in order to control a fire on a hot day. High temperatures directly contribute to the rapid growth of fires to an intensity and magnitude beyond the control capabilities of the Fire Districts in Contra Costa County. I Winds (a) Conditions Prevailing winds in many parts of Contra Costa County are form the north or northwest in the afternoons. However, winds are experienced from virtually every direction at one time or another. Velocities can reach fourteen (14) mph to twenty-three (23) mph ranges, gusting to twenty-five (25) to thirty-five (35) mph. Forty (40) mph winds are experienced occasionally and winds up to fifty-five-five (55) mph have been registered locally. During the winter half of the year, strona, %Wwdry, gusty winds from the north move through the areafor several days, creating extremely dry conditions. (b) Impact Winds such as those experienced locally can and do exacerbate fires, both interior and exterior, to burn and spread rapidly. Fires involving non-irrigated weeds, grass, brush, and fires caused by gas line ruptures can grow to a magnitude and be fanned to an intensity beyond the control capabilities of the fire services very quickly even by relatively moderate winds. When such fires are not controlled; they can extend to nearby buildings, particularly those with untreated wood shakes or shingles. 4MW Contra Costa County Findings 5 2004 California Electrical Code Winds of the type experienced locally also reduce the effectiveness of exterior water streams used by all Contra Costa County Fire Districts on fires involving large interior areas of buildings, fires which have vented through windows and roofs due to inadequate built-in fire protection and fires involving wood shake d shingle buildingan exteriors. Local winds will continue to be a definite factor toward causing major fire losses to buildings not provided with fire resistive roof and siding materials and buildings with inadequately separated interior areas, or lacking automatic fire protection systems, or lacking proper gas shut-off devices to shut off gas when pipes are ruptured, or lacking proper electrical systems. National statistics frequently cite wind conditions, such as those experienced locally, as a major factor where conflagrations have occurred. 4, Summary Due to these conditions, it is necessary for Contra Costa County to change, modify and amend the California Electrical Code.
