Adopt ordinance as follows: Ordinance No. 99 -14 An urgency ordinance of the City Council of the City of Newport Beach amending Title 15 to the Newport Beach Municipal Code to, adopt the 1997 Edition of the • Uniform Administrative Code, the 1997 Edition of the Uniform Housing Code, the 1998 Edition of the California Building Code, the 1998 Edition of the California Mechanical Code, the 1998 Edition of the California Electrical Code, the 1998 Edition of the California Plumbing Code, the 1997 Edition of the Uniform Swimming Pool, Spa and Hot Tub Code, and the Excavation and Grading Code, to take effect concurrently with the State Code on July 1, 1999. 3. Adopt Resolution No. 99-_ as follows: A resolution of the City Council of the City of Newport Beach setting forth findings based on local conditions within the City of Newport Beach which make certain modifications and changes to the California Building Code, the California Plumbing Code, and the California Electrical Code reasonably necessary. BACKGROUND This is a request to update Title 15 of the Newport Beach Municipal Code by adopting, by ordinance, the attached model code and local amendments. The introduction of the Fire and Building Codes adoptive ordinances and related amendments and first reading was conducted on May 10, 1999. The public hearing . was originally scheduled for May 24, 1999, but at the direction of the California Building Standards Commission further revisions to the original Fire Code adoptive ordinance became necessary. 1 Page 2 of 2 • The Building and Fire and Marine Departments believe that both ordinances should be scheduled for public hearing together due to similarities in scope and public interest. In order for these Codes (with specific local amendments necessary to meet Newport Beach's unique geographic, climatic and topographical conditions) to take effect with the State Code on July 1, 1999, the City Council must conduct a public hearing and adopt this urgency ordinance with an affirmative vote of at least 5 members. SUMMARY Adoption of this ordinance will keep the City in step with current regulations and will assure compliance with State law. These updated Codes are needed for enforcement of minimum standards to safeguard life, health, property, and public welfare within the City of Newport Beach.

May 10, 1999 Jay Elbettar (949) 644 -3282 SUGGESTED ACTION Introduce the ordinance, the resolution of findings for local amendments and pass to second reading on May 24, 1999. EXECUTIVE SUMMARY In accordance with State law, model codes, as published by the Building Standards Commission in Title 24, are mandated to be enforced on July 1, 1999. The attached ordinance proposal, along with the resolution of required findings for local amendments, will bring Newport Beach into compliance with that requirement. BACKGROUND Based on a November 18, 1998 ruling by the California Building Standards Commission, the 1998 California Building Codes will go into effect July 1, 1999. Section 17922 of the Health and Safety Code provides a detailed explanation of the process. Section 17958 deals with adoption of ordinances by cities. It states that cities may make changes or modifications in the State provisions adopted pursuant to Section 17922 upon express findings by the City Council that these changes are reasonable and necessary because of local climatic, geological, or topographical conditions. These local amendments, additions and deletions to the 1998 State Building Standards Code need to be in effect on July 1, 1999. Failure to do so will impose State requirements without local amendments. Each city or county adopts these codes with amendments, additions or deletions • necessary because of local climate, geological, or topographical conditions pursuant to 1 Section 18941.5 or Section 17958.7 of the Health and Safety Code. Findings must be made by the jurisdiction to any changes that are more restrictive than the standards. is adoption process takes place every three years when the model codes are published. The current adoption will be for the following codes: 1. 1998 Editions of the California Building, Mechanical and Plumbing Codes based on the 1997 Uniform Codes. 2. 1998 California Electrical Code based on the 1996 National Electrical Code. 3. The 1997 Uniform Housing and Administrative Codes. 4. The 1997 Swimming Pool, Spa and Hot Tub Code. 5. The Excavation and Grading Code. In an effort to provide consistency in code application and reduce regulations while maintaining high safety standards in Orange County, several cities joined to form a uniformity group. This group studied the local amendments of each participating city and through a consensus process reached an agreement to adopt a uniform set of amendments covering the technical provisions. The result is a total of nine amendments representing a 90% reduction in local amendments. The following list represents all participating cities: Anaheim, Brea, Garden Grove, Irvine, Laguna Niguel, Laguna Hills, Mission Viejo, Orange, Villa Park, Westminster. Newport Beach is a member of the group and the attached proposed amendments are consistent with that effort. The Administrative, Housing, Fire and Grading Codes were not addressed since each jurisdiction's application of these codes depends on their organization structure. The Building Board of Appeals heard the proposed amendments at its April 7, 1999 meeting and voted unanimously to recommend adoption of the proposed amendment to the City Council. In addition, the Building Department met with representatives of the Orange County Chapter of the Building Industry Association who attended the Board of Appeals meeting of April 7, 1999, as well and concurred with the proposed amendment. The board meeting was attended by several members of the development community as a result of approximately 100 invitations from our user group mailing list. OVERVIEW OF THE PROPOSED AMENDMENTS A summary of the proposed amendments and justifications is presented on Page 4 of this report. The Building Department evaluated the existing amendments and deleted several provisions consistent with the uniformity effort. Several provisions were also deleted to eliminate redundancies and in the interest of streamlining processes such as the Section 15.02.070 requirement for a bond for a temporary utility connection. Staff believes that processing these bonds is a long and unnecessary administrative process 2 when the amount of the bonds ($500 and $1,000 for residential and commercial • buildings, respectively) may not be a sufficient incentive to compel compliance. Staff believes that a commitment letter from a property owner would be sufficient for the purpose of granting temporary utility connections.

STATEMENT OF URGENCY - The City Council is adopting this Ordinance as an urgency measure for the following reasons: 1. The 1998 California Building Standards contain provisions for the design, construction, quality of materials, equipment, and occupancy of structures that are necessary to protect life and property from the hazards of fire, explosion, flooding, collapse, and other peril or catastrophe. 2. The health, safety, and welfare of Newport Beach residents, businesses, and visitors would be jeopardized by the inability of the Building Department to enforce provisions of 1998 California Building Standards as modified to address climatic, geographic, or topographic conditions. 3. If this Ordinance does not take affect immediately upon adoption by the City Council, Newport Beach would be unable, for a significant period of time, to enforce critical modifications to 1998 California Building Standards that are necessary to address climatic, geographic, or topographic conditions. 4. The adoption of this Ordinance as an urgency measure is necessary to preserve the health, safety, and welfare of Newport Beach residents, businesses, and visitors.

B. Geological or Flood Hazard. If, in the opinion of the Building Official, the land area for which grading is proposed is subject to geological or flood hazards to the extent that no reasonable amount of corrective work can eliminate or sufficiently reduce the hazard to human life or property, the grading permit and the building permits for habitable structures shall be denied. C. Environmental Effect, Mitigation. The Building Official may require plans and specifications to be modified in order to mitigate anticipated adverse environmental effects at proposed grading projects and he may, under circumstances where significant adverse effects of a proposed grading project cannot be mitigated, deny the issuance of a grading permit. When a categorical exemption 62 0 is not appropriate for a site of proposed grading work, the City shall cause to be prepared an initial study, which shall be submitted to the Building Official. If the initial study shows that no significant adverse environmental effects will result from the project, a negative declaration may be issued. The Building Official shall cause the site to be posted and the members of the City Council notified regarding the issuance of the negative declaration. Appeal of the Building Official's determination to issue a negative declaration shall be set forth in the State EIR Guidelines, Title 14, Section 15000 et seq., California Administrative Code.

The City Council hereby declares that it would have passed this ordinance, and each section, subsection, clause or phrase hereof, irrespective of the fact that any one or more sections, subsections, sentences, clauses and phrases be declared unconstitutional. SECTION 10. This Ordinance shall be published once in the official newspaper of the City and the same shall be effective July 1, 1999. This Ordinance was introduced at a regular meeting of the City Council of 0 the City of Newport Beach held on the day of . 1999, and was adopted on the day of . 1999, by the following vote to wit: AYES, COUNCIL MEMBERS NOES, COUNCIL MEMBERS M ATTEST: City Clerk :9 ABSENT COUNCIL MAYOR 0 RESOLUTION NO. 99 -_ A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF NEWPORT BEACH SETTING FORTH FINDINGS BASED ON LOCAL CONDITIONS WITHIN THE CITY OF NEWPORT BEACH WHICH MAKE CERTAIN MODIFICATIONS AND CHANGES TO THE CALIFORNIA BUILDING CODE, THE CALIFORNIA PLUMBING CODE, AND THE CALIFORNIA ELECTRICAL CODE REASONABLY NECESSARY. WHEREAS, Health & Safety Code Section 17958 mandates that the City of Newport Beach adopt ordinances or regulations imposing the same requirements as are contained in the regulations adopted by the State pursuant to Health & Safety Code, Section 17922; and WHEREAS, the State of California is mandated by Health & Safety Code Section 17922 to impose the same requirements as are contained in the 1997 Edition of the Uniform Housing Code of the International Conference of Building . Officials, the 1998 California Building Code based on the 1997 Uniform Building Code of the International Conference of Building Officials, the 1998 California Plumbing Code based on the 1997 Uniform Plumbing Code of the International Association of Plumbing and Mechanical Officials, the 1998 California Mechanical Code based on the 1997 Uniform Mechanical of the International Conference of Building Officials and the 1998 California Electrical Code based on the 1996 National Electrical Code of the National Fire Protection Association (hereinafter referred to collectively as "Codes "); and WHEREAS, Health & Safety Code Section 17958.5 permits the City to make such changes or modifications to the Codes as are reasonably necessary because of local conditions; and WHEREAS, Health & Safety Code Section 17958.7 requires that the City Council, before making any changes or modifications pursuant to Section 17958.5 1 make express findings that such changes or modifications are needed due to . climatic, geographic, or topographic conditions; and WHEREAS, the Building Director has recommended that changes and modifications be made to the Codes and have advised that these changes and modifications to the model codes are reasonably necessary due to local conditions in the City of Newport Beach and have further advised that the remainder of said changes and modifications are administrative or procedural in nature, NOW THEREFORE, BE IT RESOLVED by City Council of the City of Newport Beach as follows: SECTION 1. The following changes and modifications to the 1998 Editions of the CALIFORNIA BUILDING CODE as recommended by the Building Director are hereby found to be necessary due to local climatic, geographical or topographical conditions: • 1. Section 403 redefines High Rise buildings from 75 feet in height to 55 feet and modifies the application of special provisions for these buildings to all occupancies from office and residential occupancies. FINDINGS: a. The City of Newport Beach is located in an area subject to a climatic condition of high winds. This environment is conducive is to rapidly spreading fires. Control of such fires requires rapid response. Obstacles generated by a strong wind, 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 Table 16 -G identifies a significant increase in the amount of wind force at 60 2 • • 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 City of Newport Beach is located in the middle of the seismically active area identified as Seismic Zone 4. The viability of the public water system would be questionable at best after a major seismic event. This would 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 floors above the 55 - foot level. 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. 2. Section 904.2.1 and Section 904.2.2 are modified to require installation of an automatic fire extinguishing system in all occupancies exceeding 5,000 square feet before allowable floor area increases specified in Table No. 5 -B, Section 505 are applicable and in all buildings having floors used for human occupancy and located more than 40 feet above the lowest level of Fire Department vehicle access. FINDINGS: Due to the geographic conditions of widespread development separated by waterways and the street congestion caused by this geography, and due to the seismic activity and the expected infrastructure damage inherent in seismic zone 4, 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) requirement for a given structure. 3. Delete Section 1502.3 and amend Table 15 -A and footnotes to 0 the table to require roof coverings to be of fire retardant material of not less than Class C rating. FINDINGS: a. Many areas of Newport Beach have significant growths of vegetation of a highly combustible nature. b. The City of Newport Beach, especially the foothill areas, is geographically located in an area periodically subject to wind conditions of high velocity. Moreover, the topographical conditions of the foothill areas, and canyons contained therein, tend to accelerate the periodic high velocity winds by means of a venturi effect. C. The City of Newport Beach, especially the foothill areas, is located within an area subject to high temperatures, in conjunction with high winds. d. The use of non -rated or special purpose roofing materials as roof coverings within the City of Newport Beach may create an inordinate fire hazard during periods of high velocity winds when fire may spread across buildings with roof coverings of non -rated combustible materials. e. Embers from chimneys without spark arresters within the City of Newport Beach, including the foothill areas, coupled with the climatic, topographic and geographic conditions described herein above, may permit the throwing of sparks, embers and cinders upon non -rated and special purpose roofing material roofs during periods of high velocity winds, thereby creating a fire hazard which in turn may spread throughout areas where the roofs of structures are covered with untreated wood shakes and shingle. 0 • • 4. Section 1900.4.4 is amended to require vapor barriers below concrete slabs. FINDING: Most of Orange County is located above some type of aquifer that is often just a few feet below the surface. In addition, Newport Beach is subjected to potentially severe rainstorms during the winter months. Combining these two water sources with the water retention capacity of the area's expansive soil produces a condition wherein the moisture content of the soil is sufficient to increase the moisture content of concrete in contact with the soil. Concrete, which is used as part of a building structure, has the potential to transfer that moisture to the structure causing structural deterioration unless a moisture barrier is provided. 5. Section 1922.10.3 exception 2 is deleted. FINDING: Due to prevailing expansive soil conditions in Newport Beach, deleting this exception would require that slabs be reinforced with Minimum reinforcement, a typical requirement, specified routinely by soil engineers and used widely by design engineers to mitigate damage due to soil expansion and shrinkage. SECTION 2. The following changes and modifications to the 1998 Edition of the CALIFORNIA ELECTRICAL CODE as recommended by the Building Director are hereby found to be necessary due to local climatic, geographical or topographical conditions: 5 1. Article 110 -5 is amended to require that installation of smaller than #6 . AWG aluminum conductors shall be inspected continuously by an approved special inspector to insure tightness of all termination points. FINDING: Aluminum expands and shrinks at a much higher rate than other metals. This property becomes critical for smaller sizes or aluminum conductors, which may break down at termination point in a seismic event causing a fire. Orange County is located in an active seismic area (Seismic zone 4). The continuous inspection requirement will insure proper installation. SECTION 3. The following changes and modifications to the 1998 Edition of the CALIFORNIA PLUMBING CODE as recommended by the Building Director are hereby found to be necessary due to local climatic, geographical or topographical conditions: 1. Section 604.1a is amended to require non - metallic pipe for underground water service to a building. FINDING: Soil throughout Newport Beach possesses corrosive properties that reduce the expected usable life of water services when metallic pipes in contact with soils are utilized. 2. Section 1210.1 has been amended to require the installation of approved PVC or PE piping only in exterior buried piping systems. FINDING: Soil throughout Newport Beach possesses corrosive properties that reduce the expected usable life of metallic gas systems when utilized in contact with soil. C-j 0 0 SECTION 4. Additional amendments and deletions to the 1997 Edition of the Uniform Housing Code of the International Conference of Building Officials, the 1998 California Building Code based on the 1997 Uniform Building Code of the International Conference of Building Officials, the 1998 California Plumbing Code based on the 1997 Uniform Plumbing Code of the International Association of Plumbing and Mechanical Officials, the 1998 California Mechanical Code based on the 1997 Uniform Mechanical of the International Conference of Building Officials, the 1998 California Electrical Code based on the 1996 National Electrical Code of the National Fire Protection Association and 1998 California Fire Code based on the 1997 Uniform Fire Code of the International Fire Code Institute were found to be administrative or procedural and are contained in the 1997 Edition of the Uniform Administrative Code, and are found to be reasonable and necessary to safeguard life and property within the City of Newport Beach.
