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 March 20, 2002 ruling by the California Building Standards Commission, the 2001 California Building Codes will go into effect November 1, 2002. 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 2001 State Building Standards Code need to be in effect on November 1, 2002. 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 Sections 17958.7 and 18941.5(b) of the Health and Safety Code. Findings must be made by the jurisdiction to any changes that are more restrictive than the standards. The adoption process takes place every three • years when the model codes are published. The current adoption will be for the following codes 1. 2001 Editions of the California Building Code, based on the 1997 Uniform Code. • 2. 2001 Edition of the California Mechanical and Plumbing Codes based on the 2000 Uniform Codes. 3. 2001 California Electrical Code based on the 1999 National Electrical Code. In an effort to provide consistency in code application and reduce regulations while maintaining high safety standards in Orange County, the Orange Empire Chapter of ICBO formed a uniformity committee, chaired by myself. This committee 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 following list represents all participating cities: Aliso Viejo, Anaheim, Brea, Costa Mesa, Dana Point, Fountain Valley, Garden Grove, Irvine, Laguna Hills, Laguna Niguel, Laguna Woods, Mission Viejo, Placentia, Rancho Santa Margarita, Seal Beach, Tustin and 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 August 29, 2002, meeting. The board voted unanimously to recommend that the City Council adopt the proposed amendments, with the recommendation that staff evaluate the definition of floor area that triggers the installation • of a fire sprinkler system. The board meeting was attended by several members of the development community as a result of approximately 220 invitations from our user group mailing list. In addition, the Building Department met with representatives of the Orange County Chapter of the Building Industry Association who concurred with the proposed amendments. Building Department and Fire Department staff conferred and introduced an exception to define the floor area consistent with the board recommendations. The board meeting minutes will follow under a separate cover. OVERVIEW OF THE PROPOSED AMENDMENTS The proposed amendments to the model code are substantially the same as the last code adoption with the exception of a few editorial and format changes. One significant change from the last code adoption is the introduction of five amendments to the seismic design provisions of the Building Code. These amendments were necessary since the State of California through the Building Standards Commission elected to re -adopt the 1997 Edition of the Uniform Building Code. This code was developed before the Northridge earthquake and its provisions did not address the lessons learned from that event. The State Amendments to State -owned buildings, public schools and hospitals included these new provisions. The amendments relate to the construction of mid to high -rise steel structures in accordance with the latest AISC (American Institute for Steel Construction) Supplement No. 2, dated November 10, 2000. Other proposed amendments to Chapter 15 of the Municipal Code were intended to clarify and • streamline our processes, such as: 2 0 1. Amendments to Chapter 15.10, "Excavation and Grading Code" Municipal Separate Storm Sewer System Permit ( "MS4 Permit "), issued by the California Regional Water Quality Control Board, Santa Ana Region, on January 18, 2002, under the "National Pollutant Discharge Elimination System (NPDES) that the City of Newport Beach is a party to, requires that drainage water be handled differently than in the past. These amendments are an attempt to bring City policy on drainage in line with NPDES. The changes to the Excavation and Grading Code are to remove sections in direct conflict with the intent of NPDES and provide performance -based guidelines for drainage system compliance with NPDES requirements that allow the designer some flexibility. A new section is added to provide the ability to collect a runoff impact mitigation fee in cases where strict compliance is not possible and waiver is granted. This fee would address the adverse impacts from runoff elsewhere in the City. 2. Amendments to Chapter 15.15, "Report of Residential Building Record" This chapter is revised with language changes to clarify our policy on declined inspections, inspection procedure, responsibility for delivery of the report, and cancellation/refund policy. A new section was added to establish an expiration date for reports that have not received a final inspection. These amendments were heard and endorsed by the Board of Appeals previously in its August 21, 2001 meeting. • 3. Amendments to Chapter 15.50, "Flood Damage Prevention" Chapter 15.50 clarifies the difference between the development permit processing requirements and the standards of construction for a new structure, addition, and remodel of an existing structure. The flood damage prevention requirements were further clarified by introducing new definitions and restructuring the contents of Chapter 15.50. 4. Amendments to Chapter 15.60, "Construction Site Clean -up" NBMC Section 15.60.010 requires that a clean -up deposit is collected at the time of issuing a building permit. The purpose of the deposit is to ensure the removal of construction and demolition debris from construction sites and public property adjoining construction sites. It also ensures the installation of erosion control measures and desilting basins, and ensures that required inspections are requested. Collection, maintenance and refund of the site clean -up deposit are cumbersome to the Building Department and Administrative Services Department staff. It also adds to the up -front cost of a building permit and causes the owner to entrust his contractor with a refundable deposit. Moreover, holding a cash deposit without paying interest on the amount held is questionable. Deleting the requirement to collect and refund the clean -up deposit helps simplify and streamline the permitting process. The proposed amendments delete the requirement of a • clean -up deposit and authorize enforcement of site cleanup under Section 202.4 of the Uniform Administrative Code. This section authorizes the building official to stop work on a project whenever work is in violation of any provisions of the codes. The proposed 3 amendment also authorizes the Building Official to issue Administrative Citations to • provide compliance pursuant to Chapter 1.05 of the Newport Beach Municipal Code. A summary of the proposed amendments and justifications is presented on Pages 5 - 7 of this report.

Council \staffrept adopt2002cds 7 RESOLUTION NO. 2002 -_ • 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 2001 California Building Code based on the 1997 Uniform Building Code of the International Conference of Building Officials, the 2001 California Plumbing Code based on the 2000 Uniform Plumbing Code of the International Association of Plumbing and Mechanical Officials, and the 2001 California Electrical Code based on the 1999 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 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 1 • 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 2001 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 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 2 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 were 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. Section 1005.3.3.7 requires pressurized enclosures for high -rise buildings as defined where the floor level used for human occupancy is located more than 55 feet above the lowest level of Fire Department vehicle access versus 75 feet consistent with Section 403. 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 tires. 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 3 • • 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 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. • 4. Delete Section 1502.3 and amend Table 15 -A and footnotes to 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. 4 d. The use of non -rated or special purpose roofing materials as roof coverings within the City is 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. 5. Change to load combinations formula 12 -6 in Section 1612.2.1. FINDINGS: The formula accounts for both horizontal and vertical accelerations, whereas formula 12 -5 accounts for vertical acceleration, therefore formula 12 -6 was amended to account for horizontal • earthquake acceleration. This conclusion was made by the Structural Engineers Association in studies made after the Northridge earthquake. The City of Newport Beach is located in seismically active area 4 and would be affected by any future seismic events. 6. Changes to Section 1629.4.2 Seismic Zone 4 Near - Source Factor to reflect most recent design provisions as published by AISC. FINDINGS: Results from studies after the Northridge earthquake. The City of Newport Beach is located in a seismically active area identified as seismic zone 4 and in close proximity to the Newport- Inglewood fault. Results from studies after the Northridge earthquake indicated severe vertical ground acceleration causing substantial damage to buildings, 5 • • 7. Changes to Section 1630.8.2.2 Detailing Requirements in Seismic Zones 3 and 4 to reflect most recent design provisions as published by the AISC. FINDINGS: Also results from studies after the Northridge earthquake. The City of Newport Beach is located in a seismically active area identified as seismic zone 4 and in close proximity to the Newport- Inglewood fault. Results from studies after the Northridge earthquake indicated severe vertical ground acceleration causing substantial damage to buildings. 8. 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. 9. 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. 10. Changes to Section 2205.3 Design Provisions for Structural Steel to reflect most recent design provisions as published by the AISC. • 6 FINDINGS: • Also results from studies after the Northridge earthquake. The City of Newport Beach is located in a seismically active area identified as seismic zone 4 and in close proximity to the Newport- Inglewood fault. Results from studies after the Northridge earthquake indicated severe vertical ground acceleration causing substantial damage to buildings. 11. Divisions IV and V of Chapter 22 are deleted and replaced with Division IV Seismic Provisions for Structural Steel Buildings as published by the AISC. FINDINGS: Also results from studies after the Northridge earthquake. The City of Newport Beach is located in a seismically active area identified as seismic zone 4 and in close proximity to the Newport- Inglewood fault. Results from studies after the Northridge earthquake indicated severe vertical ground acceleration causing substantial damage to buildings. SECTION 2. The following changes and modifications to the 2001 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: 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. FINDINGS: 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. 7 • • SECTION 3. The following changes and modifications to the 2001 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 604.1.1 is amended to require non - metallic pipe for underground water service to a building. FINDINGS: 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. FINDINGS: Soil throughout Newport Beach possesses corrosive properties that reduce the expected usable life • of metallic gas systems when utilized in contact with soil. SECTION 4. Additional amendments and deletions to the 2001 California Building Code based on the 1997 Uniform Building Code of the International Conference of Building Officials, the 2001 California Plumbing Code based on the 2000 Uniform Plumbing Code of the International Association of Plumbing and Mechanical Officials, the 2001 California Mechanical Code based on the 2000 Uniform Mechanical Code of the International Conference of Building Officials, the 2001 California Electrical Code based on the 1999 National Electrical Code of the National Fire Protection Association and 2001 California Fire Code based on the 2000 Uniform Fire Code of the International Fire Code Institute were found to be administrative or procedural and are • g 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. SECTION 5. A copy of this Resolution together with the Ordinances adopting the City Codes shall be filed with the California Building Standards Commission and the California Department of Housing and Community Development by the City Clerk of the City of Newport Beach as required by State law (Section 17958.7 H & S Code).

"Appeal" means a request for a review of the Floodplain Administrator's interpretation of any provision of this chapter. "Area of shallow flooding" means a designated AO or AH zone on the flood insurance rate map (FIRM). The base flood depths range from one to three feet; a clearly defined channel does not exist; the path of flooding is unpredictable and indeterminate; and velocity flow may be evident.

The area is designated as Zone M on the flood insurance rate map ( i' v "Base flood" means a flood, which has a one percent chance of being ogaa4edeequaled or exceeded in any given year (also called the "100 -year flood "). Base flood is the term used through this chapter. "Basement" means any area of the building having its floor subgrade, i.e., below ground level on all sides. "Breakaway walls" are any type of walls, whether solid or lattice, and whether constructed of concrete, masonry, wood, metal, plastic or any other suitable building material which is not part of the structural support of the building and which is designed to break away under abnormally high tides or wave action without causing damage to the structural integrity of the building on which they are used or any buildings to which they might be carried by flood • waters. A breakaway wall shall have a safe design loading resistance of not less than ten (10) and 39 no more than twenty (20) pounds per square foot. Use of breakaway walls must be certified by a • registered engineer or architect and shall meet the following conditions: 1. Breakaway wall collapse shall result from a water load less than that which would occur during the base flood; and 2. The elevated portion of the building shall not incur any structural damage due to the effects of wind and water loads acting simultaneously in the event of the base flood. "Building." See "Structure." "Coastal high hazard area" means an area of special flood hazard extending from offshore to the inland limit of a primary frontal dune along an open coast and any other area subject to high velocity wave action from storms or seismic sources. It is an area subject to high velocity waters, including coastal and tidal inundation or tsunamis. The area is designated on a flood insurance rate map (FIRM) as Zone V! V30, VE, or V. "Current value of the structure" means the existing structure square footage multiplied by the cost per foot average as determined by the Building Official. • "Development" means any manmade change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials.

Also referred to as a "regulatory floodway." "Fraud and victimization" as related to Section 15.50.248190, variances, of this chapter, means that the variance granted must not cause fraud on or victimization of the public. In examining this requirement, the City of Newport Beach will consider the fact that every newly constructed building adds to government responsibilities and remains a part of the community for fifty to one - hundred years. Buildings that are permitted to be constructed below the base flood elevation are subject during all those years to increased risk of damage from floods, while future • owners of the property and the community as a whole are subject to all the costs, inconvenience, danger, and suffering that those increased flood damages bring. In addition, future owners may purchase the property, unaware that it is subject to potential flood damage, and can be incurred only at very high flood insurance rates. "Functionally dependent use" means a use, which cannot perform its intended purpose unless it is located or carried out in close proximity to water.

The City of Newport Beach requires that the variance be exceptional, unusual, and peculiar to the property involved. Mere economic or financial hardship alone is not exceptional. Inconvenience, aesthetic considerations, physical handicaps, personal preferences, or the disapproval of one's neighbors likewise cannot, as a rule, qualify as an exceptional hardship. All of these problems can be resolved through other means without granting a variance, even if the alternative is more expense, or requires the property owner to build elsewhere or put the parcel to a slightly different use than originally intended. "Highest adjacent grade" means the highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure. "Historic structure" means any structure that is 1. Listed individually in the National Register of Historic Places (a listing • maintained by the Department of Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register; 2.

"Lowest floor" means the lowest floor of the lowest enclosed area, including basement. • An unfinished or flood resistant enclosure, usable solely for parking of vehicles, building access or storage in an area other than a basement area (see "Basement ") is not considered a building's 43 lowest floor, provided that such enclosure is not built so as to render the structure in violation of • the applicable nonelevation design requirements of this chapter. (Note: This definition allows garages serving one or two dwelling units to be built at grade. Below grade garages serving one or two dwelling units are not allowed as they are considered to be basements.) "Manufactured home" means a structure, transportable in one or more sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when attached to the required utilities. The term "manufactured home' does not include a "recreational vehicle."

"Mean sea level" means, for purpose of the National Flood Insurance Program, the National Geodetic Vertical Datum (NGVD) of 1929 or other datum, to which base flood elevations shown on a community's flood insurance rate map are referenced. "Mudslide" (i.e., mudflow) describes a condition where there is a river, flow or • inundation of liquid mud down a hillside, usually as a result of a dual condition of loss of brush cover and the subsequent accumulation of water on the ground, preceded by a period of unusually heavy or sustained rain. "Mudslide (i.e., mudflow) prone area" means an area with land surfaces and slopes of unconsolidated material where the history, geology, and climate indicate a potential for mudflow. "New construction" for floodplain management purposes, means structures for which the "start of construction" commenced on or after the effective date of Floodplain management regulations adopted by this community, and includes any subsequent improvements to such structures. "New manufactured home park or subdivision" means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including at a minimum, the installation of utilities, the • 44 • construction of streets, and either final site grading or the pouring of concrete pads) is completed on or after the effective date of floodplain management regulations adopted by this community. "Obstruction" includes, but is not limited to, any dam, wall, wharf, embankment, levee, dike, pile, abutment, projection, excavation, channelization, bridge, conduit, culvert, building, wire, fence, rock, gravel, refuse, fill, structure, vegetation or other material in, along, across or projecting into any watercourse which may alter, impede, retard or change the direction and/or velocity of the flow of water, or due to its location, its propensity to snare or collect debris carried by the flow of water, or its likelihood of being carried downstream. "One- hundred -year flood" or "100 -year flood." See 'Base flood." "Primary frontal dune" means a continuous or nearly continuous mound or ridge of sand with relatively steep seaward and landward slopes immediately landward and adjacent to the beach and subject to erosion and overtopping from high tides and waves during major coastal storms.

"Principal structure" means a structure used for the principal use of the property as distinguished from an accessory use. "Public safety and nuisance" as related to Section 15.50.24$ 190, variances, of this chapter means that the granting of a variance must not result in anything which is injurious to safety or health of an entire community or neighborhood, or any considerable number of persons, or unlawfully obstructs the free passage or use, in the customary manner, of any navigable lake, or river, bay, stream, canal, or basin. "Recreational vehicle" means a vehicle, which is 1. Built on a single chassis; 2. Four hundred (400) square feet or less when measured at the largest horizontal projection; • 3.

The actual start means either the first placement or permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers, or foundations or the erection of temporary forms; nor does it include the installation on the property of accessory buildings such as garages or sheds not occupied as dwelling units or not part of the main structure. For a "substantial improvement ", the actual start of construction means • 46 . the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building. "Structure" means a walled and roofed building that is principally above ground; this includes a gas or liquid storage tank or a manufactured home.

OLD BUSINESS: - None Old Business NEW BUSINESS: New Business ITEM 1: Adoption of the 2001 Newport Beach Building Codes Adoption of the 2001 Newport Beach Chairman Root read the staff report's background for the adoption of the Building Codes 2002 Newport Beach Building Codes and Fires Codes. Recommended Building Director Elbettar stated that the proposed adoption of Newport adoption of Beach building codes included building, plumbing, mechanical and fire proposed building • codes as well. He pointed out the presentation with the first portion code to the City • City of Newport Beach Building Code Board of Appeals August 29, 2002 covering the changes the Building Department proposes to the Municipal Council Code and the adoption of the model codes with amendments. The second portion of the presentation covered the proposed Fire Code amendments by the Fire Department, presented by Fire Marshall Dennis Lockard, who was present. He explained these two ordinances were scheduled to go before the City Council on September 10, 2002, for the first reading. The first ordinance was the proposed adoption of the building, mechanical, plumbing, electrical codes, and some amendments to the Municipal Code relating to Chapter 15. The second ordinance would be the adoption of the California Fire Code and related amendments. He proceeded with the power point presentation that would explain the adoption process and included a summary of the proposed changes and amendments. He noted that this code adoption process happened every three years and that all present board members were present for the previous adoption in 1999. this adoption would be effective November 1, 2002, 63 days from today. If the City failed to adopt, then the State Code would go into effect by default without our amendments. Staff proposed to adopt the 2001 California Building Code based on the 1997 UBC published by ICBO, the 2001 California Plumbing Code based on the 2000 Uniform Plumbing Code, published by IAPMO and the 2001 California • Mechanical Code based on the 2000 Edition of the Uniform Mechanical Code, published by IAPMO, the 2001 California Electrical Code based on the 1999 Edition of the National Electrical Code, published by the National Fire Protection Association, and the 2001 California Fire Code, based on the 2000 Edition of the Uniform Fire Code, published by the Western Fire Chiefs Association. He explained that some amendments would be to the Building Code due to this adoption. This edition of the Uniform Building Code was the same edition that was adopted by the City three years ago. The State of California chose to re -adopt the some edition and not the newer edition of the model code, identified as the 2000 International Building Code. He pointed out the benefit of the IBC was one code volume versus the UBC's three volumes. The State of California chose for many reasons to stay with the 1997 code. The reason to adopt new codes every three years was because new building technology should be employed as learned from disasters or other manmade events. New buildings laws are introduced to improve our buildings for safety and habitability. About three years are required to develop a code, therefore re- adopting the 1997 Code meant working with 94/95 building codes. Unfortunately, the State chose to do so. The local codes would be effective November 1, 2002. Amendments to these model codes must be justified under one of the following reasons published by the Building Standards Commission: under local geographic, topographic or climatic conditions with findings and justifications for the • amendments. INDEX City of Newport Beach Building Code Board of Appeals • August 29, 2002 INDEX Mr. Elbeffar explained the timeline of the code adoption and summary of changes. The law required adoption of the code within 180 days after publication. He noted some changes relating to steel construction and seismic provisions. He repeated that the 1997 Code was outdated and that most, if not all, of the lessons learned from the Northridge earthquake were not implemented in the 1997 Code because the code was developed three years before the earthquake. He explained that if the 1997 Code were to be adopted today without any changes, no advantage would be taken of the lessons learned from that earthquake. Therefore, staff proposed some changes to be consistent with the American Institute of Steel Construction Seismic Supplement, published November 2000. These are changes the State of California also made because agencies realized that the 1997 Code was outdated; specifically regarding steel construction for State buildings, schools, hospitals, etc. He mentioned additional proposed Municipal Code changes, such as to the Grading and Excavation Code, the Residential Building Report Chapter, the Flood Damage Prevention Chapter, and the Construction Site Cleanup Chapter. Mr. Elbettar mentioned that the City joined the Orange County uniformity program that came about through a committee appointed by the Chapter of ICBO to study these changes. He mentioned that he was the chairman of the committee that worked very hard to develop a document that could be used for uniform amendments by cities throughout the County. The results were a total of 18 proposed amendments: 11 to the building code, of which four are general requirements and seven are structural; zero changes to the mechanical code; one amendment to the electrical code, two amendments to the plumbing code, and four to the swimming pool code. Up to this date, 18 jurisdictions had signed on with this uniformity program and committed to using this program as a core document for their code adoption, meaning the same amendments would be used by different cities. Mr. Uske asked how many jurisdictions in this County, to which Mr. Elbettar answered 31 jurisdictions, including the County, which did not signed on with the program. Mr. Jeannette asked if all cities accepted the seismic amendments and Mr. Elbettar affirmed this. Mr. Elbettar stated that the City of Newport Beach amendments numbered 19, one more than the uniform program, Involving the fire sprinklers. The uniform code amendment did not address the fire code requirements because the County has fire authority, nor did it address the grading or the administrative provisions, as each jurisdiction maintained different organizational structures and responsibilities. Each city provided Its own sprinkler codes. L Mr. Uske asked about the County's jurisdiction for Inspections for Newport Coast, which had become part of Newport Beach. He wondered what differences were experienced since the County was not a part of this uniformity program. Mr. Elbettar agreed that differences existed between • the application of the code amendments of the City and the County. 3 • City of Newport Beach Building Code Board of Appeals August 29, 2002 Mr. Jeannette asked whether the rules conflicted in the grading area also. Mr. Elbettar stated that the City's grading ordinance was based on the original County grading ordinance and was therefore very similar, with some minor differences regarding slope issues, bluffs, etc. He mentioned proposed major changes to the grading ordinance to be consistent with the new regulations of the National Pollution Discharge Elimination System Program, the NPDES. Mr. Jeannette asked about situations when new work was done to existing residences in the Pelican Hills Crest area since their existing grading issues were different than the proposed changes of today. Mr. Elbettar explained the current agreement was that the County retained jurisdiction over each planned development area until the planned area was completed. Nothing had been turned over to the City yet and the City was in constant dialogue with the County regarding these issues since October 2001. Mr. Elbettar returned to the summary tables describing the proposed code amendments. He read the changes and noted the change to the conductors and electrical code was the same as in 1999, requiring continuous inspections when torquing the aluminum wiring that could result In electrical fires. While it was rarely used anymore, it was kept in the code as a precaution. Mr. Jeannette wondered whether it should stay in the • electrical code. Mr. Steve Hook, Chief Building Inspector, said some older tracts still had some of these materials. Mr. Elbettar mentioned a change to the swimming pool code that deleted barrier requirements in lieu of adopting Article 2.5 of the Health and Safety code, the swimming pool barrier act. Staff amended this further with requirements from the Uniform Building Code, because the barrier safety act did not address isolation fencing. The Building Code required fencing the pool from the house and to the outside, which provided a much safer ordinance. Mr. Elbettar explained proposed changes to the Grading Ordinance to be consistent with the NPDES requirements. These requirements were approved by Council as policy L22 at the April 23 meeting. However, our grading ordinance was inconsistent with council policy, therefore we held up enforcement until we amend our grading ordinance. Mr. Elbettar spoke about changes to the Residential Building Records (RBRs). These were before this board at the August 21, 2001 hearing, and he recalled that one -year time limits /expiration with no action taken for the RBRs were discussed. Refund provisions were also added in the text. The intent of declining Inspection was also clarified, that if a seller chooses to allow inspection at the beginning, it could not be declined once the process has started. Declining the inspection must be chosen from the beginning. • Changes to the flood damage prevention were reviewed with the City INDEX City of Newport Beach Building Code Board of Appeals • August 29, 2002 INDEX Attorney's office and with FEMA. Changes were added to clarify the cost of construction as threshold to when the requirements would apply. The current ordinance spoke about the market value, which was very difficult to determine because the market value of a structure involved the value of the land. Therefore, the wording was switched to cost of replacement value, addressing only the building's value. Mr. Jeannette was concerned about the definition of fair market value of improvements, page 47 under substantial improvements. He noted that basically 50% of the current structure value was left up to someone to determine. He noted the 50% was unknown and asked what value the Building Department put on construction. Mr. Elbettar said $100 per sq.ff. for construction. Mr. Jeannette said as it was a codified amount, it could not be debated. However, if it could be done for less, it became a debatable issue in Mr. Jeannette's view. Mr. Elbettar said this was a very valid concern and staff had the same concern when the code contained the provision of current market value. The code spoke of the cost of replacement of the structure today, which was based on $100 per sq.ff. The reason was that a homeowner might remodel involving granite, which would increase the cost of construction, whereas the intent was to employ measures commensurate with physical improvement. There was no other way other than current value of structure or the cost of replacement value • as the previous market value wording presented a bigger problem. He believed this was a fair and equitable way. Mr. Jeannette asked whether the current value of a structure's addition was determined by the City's benchmark of $100 /sq.ff., to which Mr. Elbettor agreed. Mr. Elbettar spoke to the construction refund process changes. He explained the cleaning deposit, known as C &D, was collected on every building permit to keep the site clean without damage to public property. The deposit was refunded when the building permit was finaled. He told of an example when the deposit was forfeited about eight years ago and a request for the refund came in after that time and the deposit was challenged. Consultations with the City Attorney and City Manager determined that the cleanup deposit could not be forfeited, and the request had to be refunded. Therefore, it was decided that enough code provisions were in place to make this deposit section obsolete. To streamline this process, this deposit was proposed to be deleted from the code. He believed this would help the Industry and community as sometimes confusion was created as to who paid the deposit and who received the refund. If any violations surfaced, a stop work order or administrative citations could be issued to compel clean up. Mr. Jeannette asked if no deposit was collected, was it then left up to the Inspector's discretion to red tag a project. Mr. Elbettar agreed and stated that it always had been up to the inspector's discretion to forfeit the deposit, and the forfeit was appealable to the Building Director. Mr. • Jeannette recalled that some years ago when a building inspector felt in • City of Newport Beach Building Code Board of Appeals August 29, 2002 his opinion to red tag a project, yet ultimately it was worked out with the Building Director that the issue need not hold up the project. He was concerned that something of this nature could grind big projects with many workers to an 'expensive" halt. He wanted to establish a way to look at this issue, not to stop work on the project unless it created real jeopardy to the community, and perhaps only have the Building Director issue stop work orders. Mr. Elbettar agreed this was a valid concern. He offered to change the language to 'Building Official" instead of building inspector. However, this did not resolve the issue, as every building Inspector and plan checker was a deputized Building Official and acted on his behalf. When 'Building Official" was used throughout the code, it referred to every deputy. He stated that Mr. Jeannette's concern was already addressed by Implementing a new stop work policy one month ago, for which training started September 5th. Mr. Uske asked as to how many times the cleaning deposits were forfeited in the past. Mr. Elbettar said that about 1 % of the deposits were forfeited for a total of $20,000 per year. However, the validity of these forfeitures was being questioned now. Mr. Uske said he believed the large projects seemed to be under extreme tight scrutiny, however, he observed some of the residential remodels in the City where concrete went into the gutter • and bay as runoffs, etc. He was concerned about more policing of this problem. Mr. Elbettar stated that one of the City's goal this year was to comply with all the NPDES standards, Including educational outreach programs, mailers to builders, etc. A display board to educate builders and contractors of the requirements not to dump materials in the gutter, etc., would be completed soon. Building inspectors were also trained with a presentation acquired from the County to look for measures to prevent discharges into the storm drains. Code Enforcement Officer Jim Sinasek was also very proactive. New filters were installed on the catch basins as part of a citywide awareness program, headed by water quality unit with Dave Kiff in charge. All City departments were implementing their part to eliminate these discharges. Mr. Lockard stated that the City was very fortunate to have a Building Official with the quality of Mr. Elbettar. He felt it was important to be present before this board because the Fire Department's goals mirrored this board's commitment by working towards Insuring safe buildings in Newport Beach. He noted the 2000 Uniform Fire Code was being adopted this year as adopted by State of California. He noted that different jurisdictions were working towards more consistency, which presented an advantage for builders and developers throughout the County. The 2000 proposed Fire Code had a total of 46 changes, most existed previously, and amending some of them. He addressed the Newport Coast issue regarding the wild • land areas. As a result of the 1994 Oakland and Laguna Beach fires, many concerns were addressed by a plan called 'Fuel modification," that INDEX City of Newport Beach Building Code Board of Appeals August 29, 2002 INDEX* managed a distance into the wild land and the types and amount of fuels. This was adopted in the 1999 code and continued in the present proposed code adoption. The standards were exactly the same as the Orange County Fire Code, providing the community with the same sense of protection. He briefly explained the changes in the table. He spoke to 9.04.040 addressing deleting permit requirement for hydrants and to require a permit for a listed heater in commercial occupancies. Because of dangers associated with compressed gas, Newport Beach prohibited propane heaters as a permanent heating device. A fire alarm system with smoke detectors must be maintained with written records provided by a qualified professional. He noted a problem with the 1999 code regarding floor area definition. Therefore, the same definition as the Building Code was used to be consistent in both codes. Sprinkler requirements were now consistent in the building and fire codes. Mr. Jeannette asked if an exterior area was covered by trellis or overhang, would that not count for area of structure in determining sprinklers. Mr. Lockard answered that the fire code was referring to the building code's definition. Mr. Elbettar explained it stated, 'Usable space under roof or any horizontal projection." A trellis would not have to comply, but an overhead • or patio cover used for barbecue or other activities that could be a source of fire must comply. The code defined the floor area, not the habitable area. Mr. Jeannette asked whether the many large loggias of homes in the Pelican Hill area contributed to the building's square footage requiring sprinklers. Mr. Elbettar said yes, if they were attached to the building and usable, which was also required in the County Fire Code. Mr. Lockard said the Fire Code referenced that Newport Coast area structures and appendages must be sprinklered, regardless of footage, the same as required by the County Fire Code. Mr. Lockard mentioned another requirement for all fire alarm and sprinkler systems to be central- system monitored. Mr. Uske asked if the requirement was to be retroactive and Mr. Lockard said yes, the code required supervision for more than 100 sprinkler heads in a building, or for certain occupancies such as hospitals. He noted the example of the Hoag Hospital with a central monitoring station and onsite supervision. Mr. Liske said he knew of quite a few large industrial buildings in the City of Costa Mesa that were not monitored. Mr. Lockard could not speak to other jurisdictions, but believed that most of Newport Beach's large buildings complied. He then spoke to a new section calling for a soil assessment report when combustible soil gases existed, such as at Hoag Hospital and at Chilli's Restaurant. This provided the Fire Department with an opportunity to see the report and how it was mitigated to insure the building's safety. He also noted battery systems would be regulated. He spoke about the • requirements for protected above ground tanks, regulating the amount of • City of Newport Beach Building Code Board of Appeals August 29, 2002 stored chemicals, treatment systems for highly toxic gases, which must be able to shut off automatically for safety. National Fire Protection Association standards were adopted as much as possible. Mr. Jeannette asked about the fire sprinkler requirements and recalled too many situations where a building may be large enough that even a small addition could add the total to exceed 5,000 sq.ff. and automatically trigger the fire sprinkler requirement. He realized the present code talked about the percentage of an addition to the residence, therefore from 0 - 25% no sprinklers are required even for the new area. He wondered whether this new aspect of counting the covered area, would adding a mere 50 sq.ff. covered patio, if exceeding the 5,000 sq.ff., kick in the sprinkler requirement. Mr. Lockard said the basis for the 5,000 sq.ff. sprinkler requirement was based on the Fire Department's determination on how big a fire was possible for the type of construction and what resources were available. The Fire Department determined that a fire based up to 5,000 sq.ff. could be fought based on deployment of resources. In a residential system, sprinklers were designed to prevent a flash over, while In a commercial building it was designed to protect the content. The 5,000 sq.ff. number was based on resource allocations of eight stations in Newport Beach. He noted that 85% of California's population was • protected by a more restricted sprinkler ordinance than here. Mr. Lockard said for a building with patios over 5,000 sq.ff., the definition of floor area would be considered for the sprinkler requirements. He repeated that from 0 - 25% meant no sprinkler requirement, for 25 - 50% the addition must be sprinklered, over 50% the complete structure required sprinklers. This was consistent with the State Fire Code. Mr. Jeannette posed an example of a 1,500 sq.ff. house with a,500 ft. patio. Mr. Lockard said the patio would present 33% and would require only the addition to be sprinklered. Mr. Elbettar said the City did not apply the floor area definition correctly early on and he noted that the size of a structure dictated the response. A fire in a 2,000 sq.ft. structure was different than in a.500 sq.ff. structure. The Code talked about usable space, proximity of property line, and treated patio covers as hazard in case of a source of flame under the cover shooting up or sideways. A patio cover close to the property line always required a wall or some other protection. Staff could review this, but he believed this was actually something positive for the residents as these were safety measures, and are also used as savings for insurance. Mr. Jeannette stated that not many other cities applied it this proposed way. Most cities applied this requirement as Newport Beach did In the past. He spoke from his experience as an architect all over the County and cited an example of an older couple in a small older house wishing to fix it up a bit and now would be forced to retrofit fire sprinklers for the entire house if the addition exceeded the threshold. These older people might not be able to afford this. He asked the City to look closer at the demographics and be more site • specific. He didn't believe this was dealt with equitably citywide and asked for more thoughts and consistency on this issue. He noted that Laguna INDEX City of Newport Beach Building Code Board of Appeals • August 29, 2002 INDEX Beach with all their problems still did not require fire sprinklers on exisfing buildings or any building less than 5,000 sq.ff. even though their fire hazard was much higher than Newport Beach. Mr. Lockard said he could not speak to other city jurisdictions other than that Laguna Beach had a new Fire Marshall, who previously worked for Newport Beach, and who might change their codes. He believed that Newport Beach was fortunate to have a very knowledgeable Building Official and a reasonably professional Fire Division that looked at each of these cases very critically and provided reasonable decisions. He appreciated Mr. Jeannette's concern and said staff was trying to apply the code as best as possible. One very important Item he wanted to mention was that people did usually not die in sprinklered buildings. This was the essence of the Fire Department's first mission that no one died on his watch. In his past 25 years in the profession, he had seen the success of sprinklers in buildings and also had seen tragedy of fires in buildings without sprinklers. He believed this was a fundamental way to protect the community. Mr. Cranston asked what protection was required for above ground tanks. Mr. Lockard said they must be listed, meaning Underwriter laboratories or another recognized testing laboratories created some special confinement around tanks to resist fire from exterior for two hours. Mr. Uske asked if the City had any above ground tanks. Mr. Lockard said yes the City had three or four, most either for emergency generators or maintenance equipment, such as the one in Big Canyon to fuel their equipment. Mr. Elbettar commented on Mr. Jeannette's concerns regarding habitable floor area versus floor area as a very complex issue. A structure of 500 sq.ft. with 4,500 covered spaces for RVs was an example of the difficulty of where to draw the line. He understood Mr. Jeannette's quest for a better definition of a habitable area. He encouraged Mr. Jeannette to go on record and to pursue this with a motion to recommend these amendments with the exception of this definition to change the habitable floor area. It would be mentioned and voted on at the City Council and he invited Mr. Jeannette and all board members to be present at the September 10 Council meeting to present their views. Mr. Jeannette spoke for the record that he agreed with Fire Marshal Lockard that Mr. Elbettar was one of the finest Building Officials he every met, and the fairness with which he treated all people that live, work and do construction in Newport Beach was exemplary. He agreed that his concern was not with the ordinance, but with the definition. He believed this issue needed to be looked at more thoroughly, either to the point where he felt more comfortable with or use the Building Official's capabilities to look and weigh these issues as there would be unusual circumstances coming up, requiring a reasonable and fair response without having each one come up for an appeal. Mr. Uske mentioned that there was an audience. • • City of Newport Beach Building Code Board of Appeals August 29, 2002 Mr. Root opened the public hearing. il.>� i Dolores Offing, Newport Beach, spoke to this new fire application for square footage. Her husband had a brand new Cadillac some years ago and they received a phone call not to park the car in the garage or near the home because there was a generator that could ignite and could burn down the house. She encouraged Mr. Jeannette to bring his concerns to the Council, but she understood since that day that cars parked under overhangs could easily pose a fire hazard. She spoke to the sprinklers ordinance and said if she wanted to add a 1,000 sq.ft. addition to a 3,800 sq.ft. home, she understood the addition must be sprinklered, but not the 3,800 sq.ft. home, since the addition was not more than 50% of the original house, without any overhangs or patios attached to her house. Was this correct? Mr. Elbettar said that no sprinklers would be required since the total square footage was not over 5,000 sq.ft. Ms. Offing said she would sprinkler it anyway for safety. She asked whether the County received the money from the permits pulled for Newport Coast. Mr. Lockard explained that the County was currently responsible for all Newport Coast construction, including additions in Newport Coast until that planning • area was complete. There are a total of 25 planning areas. Eight areas were completed, but nothing had been turned over since annexation. When they are turned over to the City, the Building and Fire Departments would begin permitting alterations of the completed planning areas. Ms. Offing did not understand page 13, 'Choosing to decline inspection." Mr. Elbettar explained this dealt with the residential record program. When a property was sold through escrow, the buyer must file an application through the residential record program and the City researched the property record, printed a document showing all prior permits and Inspected the property. The property owner has the right to refuse inspection and decline it. The owner and buyer would then be aware that inspection had been declined. Some confusion occurred when some owners gave inspection consent in the beginning of the process and after the Inspector found violations, the owner then wanted to decline. This amendment clarified that this inspection must either be accepted or declined at the beginning, otherwise the Inspector's findings of possible violations must be acknowledged and corrected. Mr. Jeannette wondered whether it was prudent for the buyer to automatically ask the seller to provide the copy of the record. Mr. Elbettar said some buyers do decline inspections, but they always received copies of the research record and knew whether the seller had declined inspection. Mr. Root closed the public hearing. • Mr. Jeannette asked whether it was allowed to use the PEX type of plumbing for reversed osmosis systems. Mr. Elbettar said the reason the 10 City of Newport Beach Building Code Board of Appeals August 29, 2002 INDEX • code adoption process was delayed by the Building Standards Commission from March to May was specifically because of that issue. It was included in the plumbing codes, but certain interests lobbied and allowed this option to be excluded from the code. He mentioned that he testified before the committee at that time and asked to keep that option for his jurisdiction. They at least allowed the local Building Official to make findings through 'Alternate methods and materials" on a case -by -case basis. It was a political battle and the PEX company filed a lawsuit against the Building Standards Commission and the trade unions were against it. Mr. Jeannette asked whether in Newport Beach this PEX material was covered under "Alternate methods and materials," and Mr. Elbettar said yes. Motion was made by Board member Jeannette to recommend to the City Council to consider the adoption of the 2001 California Building Code, the 2001 California Mechanical Code, the 2001 California Plumbing Code, the 2001 California Electrical Code, the 2001 California Fire Code, and the proposed amendments to these codes and other provisions of the Municipal Code as outlined in the proposed ordinances. He also asked that Council review for more clarity, as recommended by the Building Official and himself, the definition of habitable space and the application of habitable space when determining the requirements for fire sprinklers within the City. Mr. Uske seconded the motion and the Motion carried by acclamation. - None sss ADJOURNMENT: 4:05 p.m. Communications Adjournment MONIKA GO IN, RECORDING SECRETARY CITY OF NEWPORT BEACH BUILDING BODE BOARD OF APPEALS 11 •
