NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF TEMECULA DOES HEREBY RESOLVE, DETERMINE, FIND, AND ORDER AS FOLLOWS: Section 1. The City Council of the City of Temecula finds that the following amendments and modifications to the Temecula Municipal Code and the California Building Code, 2001 edition, the California Mechanical Code, 2001 edition, the California Plumbing Code, 2001 edition, and the California Electrical Code, 2001 edition, Administrative Code, 2001 edition, International Code for the Abatement of Dangerous Buildings, 2000 edition, California Housing Code, 2001 edition, International Swimming Pool, Spa and Hot Tub Code, 2000 edition, contained in Ordinance 02-_ are reasonably necessary due to consideration of specific local climatic, geological or topographical conditions as follows: Rescslrescs 2002102.98 I I I I. SECTION 15.04.020 CALIFORNIA BUILDING CODE. The following amendments, additions and deletions are made to the California Building Code, 2001 Edition, adopted by this Chapter. A. Section 106.2 is hereby amended by modifying subsection five (5) to read as follows: 5. Retaining walls which are not over two (2) feet in height, and garden walls not over four (4) feet in height, measured from the top of footing to top of wall unless supporting a surcharge or impounding flammable Class I, Class II or III-A liquids. This amendment is reasonably necessary because of the following local conditions: Geoloaical Conditions: The City of Temecula is located in an area near high seismic activity. Because of the degree of the City's urbanization and close proximity to major fault lines, the risk of structural damage and loss of life due to ground shaking is considerable. During a major earthquake, emergency resources would be extremely taxed, and the ability to respond to such emergencies would be complicated. Local standards in excess of statewide minimums will assist in reducing risks associated with earthquakes and the consequent disruption of traffic flow. B. Section 304.1 is amended by adding the following exception: Exception 1. In the Old Town Specific Plan area, for the purpose of determining required sanitation facilities, B occupancies shall be those with an occupant load of fifty (50) or less. Section 304.1 This amendment is administrative in nature necessitated by the space restrictions in Old Town to accommodate modifications of accessible restroom fixtures. This amendment is in line with the B occupancy criteria of 50 or less occupant as provided in the California Building Code. C. Section 1202.2.6 is hereby amended by adding: When mechanical ventilation is required in a Group S, Division 3 repair garage, the ventilation shall comply with the design provision in Section 1202.2.4 Section 1202.2.6. This amendment is reasonably necessary because of the following local conditions Climatic Conditions: Generally Riverside County and the City of Temecula has an arid climate. Annual temperatures can range from 30 degrees to 105 degrees resulting in the use of closeable openings for all occupancy types necessitating in the use of mechanical ventilation. Resoslresos 2002102-98 2 I' I I D. Section 1503 is hereby amended to read as follows: The roof covering or roofing assembly on any structure regulated by this Code shall be as specified in Table No. 15-A and as classified in Section 1504, except that no roof covering shall be less than a Class B roofing assembly. Exception: 1. The roof covering or roofing assembly on any structure regulated by this Code within the Historical District Overlay, generally known as the Old Town Temecula Historical Preservation District, shall not be less than a Class C roofing assembly. 2. The roof covering or roof assembly of all re-roofing shall conform to the applicable provisions of this Section as amended herein, except that the roof covering for the re-roofing of ten percent (10%) or less of the area of any roof may consist of material comparable to the remainder of the roof. Section 1503 Roof-Covering Requirements... This amendment is reasonably necessary because of the following local conditions: Climatic Conditions: Generally Riverside County and the City of Temecula has an arid climate. Annual rainfall varies from 3 inches in Blythe to over 33 inches in Pine Cove. Hot, dry Santa Ana winds are common to areas within Riverside County. These climatic conditions cause extreme drying of vegetation and common building materials and predispose the area to large destructive fires. Higher building standards are necessary to protect against the increased risk of fire. E. Section 1900.4.4 is hereby amended to read as follows: The minimum thickness of concrete floor slabs supported directly on the ground shall not be less than three and one-half (3%) inches. All group R occupancies shall have a minimum six (6) mil moisture barrier with minimum two (2) inch sand cover. Exception 1. A moisture barrier shall not be required under slabs on grade of open or enclosed patios as defined in Section 217. F. Section 1900.4.4.1 is hereby further amended by adding thereto a new paragraph to read as follows: Slab Dowels.

Embedment to existing shall be a minimum of six (6) inches. For slab cuts 24" or greater shall also conform with these provisions. Resoslresos 2002102-98 3 I I I Section 1924. Minimum Slab Thickness...; and Section 1924.1 Slab Dowels... These amendments are reasonably necessary because of the following local conditions: Topoaraphical Conditions: The City is comprised of varying soil conditions and a fluctuating water table that is fed by artesian springs. This water table will elevate substantially following heavy rain. The addition of a moisture barrier will mitigate excess moisture absorption into concrete placed on grade. Geoloaical Conditions: The City of Temecula is located Seismic Zone NO.4 and contains two (2) faults running north and south within it's boundaries. The addition of slab dowels as an additional means of attachment of added structures to existing is intended to help mitigate the effects of seismic activity on these connections. G. Appendix Chapter 4. Section 421.1 paraaraph 1 Requirements is hereby amended to read as follows: 421.1 Outdoor Swimming Pool. An outdoor swimming pool shall be provided with a barrier that shall be installed, inspected and approved prior to plastering or filling with water. The barrier shall comply with the following: 1. The top of the barrier shall be at least 60 inches above grade measured on the side of the barrier that faces away form the swimming pool. The maximum vertical clearance at the bottom of the barrier may be increased to 4 inches (102 mm) when grade is a solid surface such as a concrete deck, or when the barrier is mounted on top of the above-ground pool structure. When barriers have horizontal members spaced less than 45 inches (1143 mm) apart, the horizontal members shall be place on the poolside of the barrier. Any decorative design work on the side away from the swimming pool, such as protrusions, indentations or cutouts away from the swimming pool, which render the barrier easily climbable. is prohibited. Appendix Chapter 4. Section 421.1 paragraph 1 is considered to be administrative in nature and necessary in order to allow for a 54 inch release mechanism height from grade specified. II. SECTION 15.04.030 CALIFORNIA MECHANICAL CODE. The following amendments, additions and deletions are made to the California Mechanical Code, 2001 Edition adopted by this Chapter. Resoslresos 2002102-98 4 I I I A. Section 504 is hereby amended by adding the following: Section 504.1 makeup and exhaust ducts. Bathroom and laundry room exhaust ducts may be of gypsum wallboard subject to the limitation of Section 1002 (a). Aluminum flex ducts are not permitted to be installed horizontally in rooms that produce steam. An angle greater that forty-five degrees from the vertical is considered a horizontal run. Section 504.1 Makeup and exhaust ducts... This amendment is reasonably necessary because of the following local conditions: Climatic Conditions: Due to the proximity to the ocean and the influx of moist air experienced in the City, water deposited in the corrugated depressions of the aluminum flex ducting will not properly evaporate, thus creating a potential for stagnation, mildew, and possible excessive build up. III SECTION 15.04.40 CALIFORNIA PLUMBING CODE. The following amendments, additions and deletions are made to the California Plumbing Code, 2001 Edition adopted by this Chapter. A. Section 413.1 is amended by adding the following: In Groups B.F.H.M. and S Occupancies, buildings or portions thereof where persons are employed shall be provided with at least one water closet for each sex when the number of employees exceeds four. Separate facilities shall be provided for each sex when the number of employees exceeds four. Such toilet facilities shall be located either in such building or conveniently in a building adjacent thereto on the same property. Such water closet room in connection with food establishments where food is prepared, stored or served shall have a non-absorbent interior finish as specified in Section 807.1 of the California Building Code, shall have hand-washing facilities therein or adjacent thereto, and shall be separated from food preparation or storage rooms as specified in section 302.6 of the California Building Code. Section 413.1 This amendment is administrative in nature. The deletion of this section is made in lieu of utilizing Chapter 29 and Appendix Chapter 29 of the California Building Code as the standard for establishing required number of plumbing fixtures. B. Section 719.5 is amended to read as follows: Cleanouts installed under concrete or asphalt paving shall be made accessible by yard boxes, or extended flush with paving with a "brass cap" or other approved material for installation where subject to vehicular traffic. Resoslresos 2002102-98 5 I I I c. D. Section 719.5This amendment is administrative in nature intended to clarify an approved material for clean out installations. This is in answer to our history of inquiries on this subject. Section 1202 is amended by adding the following: Section 1202. Downstream of Gas Utility - that portion of a gas piping which is away from the gas utility meter and is on the user or customer side of the meter serving a building or structure. Section 1202.8.1 - Residential Building - any single family dwelling, duplex, apartment building, condominium, town house, lodging house, congregate residence, hotel or motel. 1202.81 Seismic Gas Shutoff Valve - a system consisting of a seismic sensing means and actuating means designed to automatically actuate means designed to automatically actuate a companion gas shut off means installed in a gas piping system in order to shut off the gas downstream of the location of the gas shutoff means in the event of a severe seismic disturbance. The system may consist of separable components or may incorporate all functions in a single body. The terms "Seismically Activated Gas Shutoff Valves" and "Earthquake Sensitive Gas Shutoff Valves" are synonymous. Section 1204.3.2 is amended by adding the following: Testing of gas piping greater than two and one quarter (21,4) inches in outside diameter and all medium pressure gas piping, shall require a twenty-four (24) hour graph test witnessed by the jurisdiction. Such test shall be at sixty (60) p.s.i. Section 1204.3.2 Final Piping Inspection This amendment is reasonably necessary because of the following conditions: Climatic Conditions: Generally Riverside County and the City of Temecula has an arid climate. Hot, dry Santa Ana winds are common to areas within Riverside County. These conditions contribute significantly to the fluctuation of air pressure in gas plumbing lines. In lines larger that two (2) inches these fluctuations are subtler because of the volume, hence detecting a small leak becomes more difficult in the code prescribed time frame of ten minutes. E. Section 1211 is amended by adding the following: 1211.22 The installation of Seismic Gas Shutoff Valves shall comply with the following requirements: a. Be installed by a contractor licensed in the appropriate classification by the State of California. Resoslresos 2002102-98 6 I I I Exception: Seismic gas shutoff valves may be installed by a gas utility provided a permit is obtained and the valves are installed and approved in accordance with this section. b.
