Both the State of California and County of Los Angeles have completed their adoption process and the City will now adopt the County Codes — Titles 26 through 31. Staff Recommendation It is recommended that the City Council take the following actions: 1. Move to INTRODUCE and ADOPT, by title only, Urgency Ordinance No. 938 (Attachment "A ") An Ordinance of the City Council of the City of Rosemead adopting by reference, pursuant to Government Code Section 50022.2, the California Building Standards Code (Title 26 Los Angeles County Building Code), the California Electrical Code (Title 27 Los Angeles County Electrical Code), the California Plumbing Code (Title 28 Los Angeles County Plumbing Code), the California Mechanical Code (Title 29 Los Angeles County Mechanical Code), the California Residential Code (Title 30 Los Angeles County Residential Code), the California Green Standards Building Code (Title 31 Los Angeles County Green Building Standards Code), and adopting local amendments thereto and declaring the urgency thereof; and 2. Move to INTRODUCE FIRST READING, by title only, Ordinance No. 939 (Attachment "B ") An Ordinance of the City Council of the City of Rosemead adopting by reference, pursuant to Government Code Section 50022.2, the California Building Standards Code (Title 26 Los Angeles County Building Code), the California Electrical Code (Title 27 Los Angeles County Electrical Code), the California Plumbing Code (Title 28 Los Angeles County Plumbing Code), the California Mechanical Code (Title 29 Los Angeles County Mechanical Code), the California Residential Code (Title 30 Los Angeles County Residential Code), the California Green Standards Building Code (Title 31 Los Angeles County Green Building Standards Code), and adopting local amendments thereto. ITEM NUMBER: City Council Report December 10, 2013 Page 2 of 3 BACKGROUND The State of California Building Standards Commission (BCS) adopts mandatory State wide Building Laws on a tri- annual basis. In January 2013, the BCS adopted the latest model codes after making amendments based on California requirements. The State Building Laws were published on July 1, 2013. Local jurisdictions have 180 days to adopt the State Building Laws and to make any amendments based on local geographic, topographic, climatic and environmental conditions. The State Building Laws become effective statewide on January 1, 2014. Since incorporation, the City of Rosemead has adopted the County of Los Angeles Building Laws which both amends and adopts the State Building Laws and Fire Code. On November 26, 2013 the Los Angeles Board of Supervisors adopted Titles 26 (Building), 27 (Electrical), 28 (Plumbing), 29 (Mechanical), 30 (Residential) and 31 (Green Building Standards) which adopted the California Building Laws with amendments and made the necessary findings based on climatic, typographical and geologic conditions. The adoption date by the County does not allow sufficient time for the normal City ordinance adoption process. Therefore in order for the City's new buildings laws to become effective on January 1, 2014, the City must adopt the County ordinances by an urgency ordinance. Therefore, the City Council will be asked to adopt Urgency Ordinance No. 938, as well as introducing non - urgency Ordinance No. 939 adopting the County Codes. Copies of the County Ordinances are available in the City Clerk's Office. DISCUSSION: The State adopted the same group of model building, electrical, plumbing, and mechanical and fire codes that they adopted in 2010. The new codes are 2012 editions (2011 for National Electrical Code) and are the result of the national three (3) year cycle of code updates and amendment processes. In this code cycle there are no new major code changes or additional codes. Los Angeles County staff as well as the City of Rosemead staff participated in the development of specific code amendments for Los Angeles County through the Los Angeles County Region Code Program (LACRUP). This program's recommendations are the basis for the County amendments, which the City of Rosemead is adopting. The revisions to Title 15 and 8 of the Rosemead Municipal Code that are herein recommended include: City Council Report December 10, 2013 Paoe 3 of 3 BEFORE California Building Code 2010 AFTER California Building Code 2013 Title 26 Los Angeles County Building Code 2010 Title 26 Los Angeles County Building Code 2013 California Plumbing Code 2010 California Plumbing Code 2013 Title 28 Los Angeles County Plumbing Code 2010 Title 28 Los Angeles County Plumbing Code 2013 California Electrical Code 2010 California Electrical Code 2013 Title 27 Los Angeles County Electrical Code 2010 Title 27 Los Angeles County Electrical Code 2013 California Mechanical Code 2010 California Mechanical Code 2013 Title 29 Los Angeles County Mechanical Code 2010 Title 29 Los Angeles County Mechanical Code 2013 California Residential Code 2010 California Residential Code 2013 Title 30 Los Angeles County Residential Code 2010 Title 30 Los Angeles County Residential Code 2013 California Green Standards Code 2013 Title 31 Los Angeles County Green Standards Code 2010 Title 31 Los Angeles County Green Standards Code 2013 ENVIORNMENTAL ANALYSIS These Ordinances has been determined to be exempt from the California Environmental Quality Act pursuant to State Guidelines 15061(b)(3) as a project that has no potential for causing a significant effect on the environment.

Polly Low, Mayor City of Rosemead, California ATTEST: Gloria, Molleda, City Clerk City of Rosemead, California: APPROVED AS TO FORM Rachel H. Richman, City Attorney Burke, Williams & Sorensen, LLP 0 ATTACHMENT C Reserved ANALYSIS This ordinance repeals those provisions of Title 26 - Building Code of the Los Angeles County Code, which had incorporated portions of the 2010 Edition of the California Building Code by reference and replaces them with provisions incorporating portions of the 2013 California Building Code, published by the California Building Standards Commission, by reference, with certain changes and modifications. State law requires that the County's Building Code contain the same requirements as are contained in the building standards published in the most recent edition of the California Building Code. State law allows the County to change or modify these requirements only if it determines that such changes or modifications are reasonably necessary because of local climatic, geological, or topographical conditions. The changes and modifications to requirements contained in the building standards published in the 2013 California Building Code which are contained in this ordinance are based upon express findings, contained in the ordinance, that such changes are reasonably necessary due to local climatic, geological, or topographical conditions. This ordinance also makes certain modifications to the administrative provisions of Title 26 and to certain chapters of Title 26 that relate to subjects not covered by the California Building Code.

Some of those changes are administrative in nature in that they do not constitute changes or modifications to requirements contained in the building standards published in the California Building Standards Code. Pursuant to California Health and Safety Code sections 17958.5, 17958.7, and 18941.5, the Board of Supervisors hereby expressly finds that all of the changes and modifications to requirements contained in the building standards published in the California Building Standards Code contained in this ordinance, which are not administrative in nature, are reasonably necessary because of local climatic, geological, for topographical conditions in the County of Los Angeles as more particularly described in the table set forth below. BUILDING CODE AMENDMENTS Code Condition Explanation of Amendment Section 701A.1 Climatic Clarifies the application of Chapter 7A to include additions, alterations, and /or relocated buildings. Many areas of the County have been designated as Fire Hazard Severity Zones due to low humidity, strong winds, and dry vegetation. Additions, alterations, and /or relocated buildings have the same fire risk as new buildings. 701A.3 Climatic Clarifies the application of Chapter 7A to include additions, alterations, and /or relocated buildings. Many areas of the County have been designated as Fire Hazard Severity Zones due to the increased risk of fire caused by low humidity, strong winds, and dry vegetation. Additions, alterations, and /or relocated buildings have the same fire risk as new buildings. 701A.3.1 Climatic Clarifies the application of Chapter 7A to include additions, alterations, and /or relocated buildings. Man j HOA.991471.2 141 Code Condition Explanation of Amendment Section areas of the County have been designated as Fire Hazard Severity Zones due to the increased risk of fire caused by low humidity, strong winds, and dry vegetation. Additions, alterations, and /or relocated buildings have the same fire risk as new buildings. 703A.5.2 & Climatic Disallows the use of wood - shingle /wood -shake roofs due 703A.5.2.2 to the increased risk of fire in the County caused by low humidity, strong winds, and dry vegetation in high fire severity zones. 704A.3 Climatic Disallows the use of wood - shingle /wood -shake roofs due to the increased risk of fire in the County caused by low humidity, strong winds, and dry vegetation in high fire severity zones. 705A.2 Climatic Disallows the use of wood - shingle /wood -shake roofs and requires the use of Class A roof covering due to the increased risk of fire in the County caused by low humidity, strong winds, and dry vegetation in high fire severity zones. 1029.4 Geological The greater Los Angeles /Long Beach region is a densely populated area having buildings constructed over and near a vast array of earthquake fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed amendment is intended to prevent occupants from being trapped in a building and to allow rescue workers to easily enter after an earthquake. 1507.3.1 Geological Section amended to require concrete and clay tiles to be installed over solid structural sheathing boards only, due to the increased risk of significant earthquakes in the County. The changes in Section 1507.3.1 are needed because there were numerous observations of the roofs pulling away from wood framed buildings following the 1994 Northridge Earthquake. Where sheathing beneath the the roofs was not nailed adequately or the nails were not attached on each side of each tile or the nail just pulled out over a period of time because the shank of the nails were smooth. The Structural Engineers Association of Southern California ( "SEAOSC ") and the Los Angeles City Joint Task Force committee findings indicated significant problems with tile roof due to inadequate design and /or construction. Therefore, the amendment is HOA.9914712 142 Code Condition Explanation of Amendment Section needed to needed to minimize such occurrences in the event of future significant earthquakes. Table Geological Table amended to require proper anchorage for clay or 1507.3.7 concrete tiles from sliding or rotating due to the increased risk of significant earthquakes in the County. Design provisions developed based on detailed study of the 1994 Northridge and the 1971 Sylmar earthquakes need to be incorporated into the local building code. 1613.6 Geological The inclusion of the importance factor in this equation has through the unintended consequence of reducing the minimum 1613.6.1 seismic separation distance for important facilities such as hospital, school, police, and fire station, etc., from adjoining structures. The deletion of the importance factor from Equation 16-44 will ensure that a safe seismic separation distance is provided. This amendment is a continuation of an amendment adopted during previous code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 1613.6.2 Geological Observed damages to one - and two- family dwellings of light frame construction after the Northridge Earthquake may have been partially attributed to vertical irregularities common to this type of occupancy and construction. In an effort to improve quality of construction and incorporate. lessons learned from studies after the Northridge Earthquake, the modification to ASCE 7 -05 Section 12.2.3.1 by limiting the number of stories and height of the structure to two stories will significantly minimize the impact of vertical irregularities and concentration of inelastic behavior from mixed structural systems. This . amendment is a continuation of an amendment adopted during previous code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 1613.6.3 Geological A SEAOSC and Los Angeles City Joint Task Force investigated the performance of concrete and masonry construction with flexible wood diaphragm failures after the Northridge earthquake. It was concluded at that time that continuous ties are needed at specified spacing to control cross grain tension in the interior of the diaphragm. Additionally, subdiaphragm shears need to be limited to control combined orthogonal stresses within the HOA.991471.2 143 Code Condition Explanation of Amendment Section diaphragm. Recognizing the importance and need to continue the recommendation made by the task force, but also taking into consideration the improved performance and standards for diaphragm construction today, a proposal to increase the continuous tie spacing limit to 40 ft in lieu of 25 ft and to use 75 percent of the allowable code diaphragm shear to determine the depth of the sub - diaphragm in lieu of the 300 pif is deemed appropriate and acceptable. The Los Angeles region is within a very active geological location. The various jurisdictions within this region have taken additional steps to prevent roof or floor diaphragms from pulling away from concrete or masonry walls. This decision was made due to the frequency of this type of failure during the past significant earthquakes. This amendment is a continuation of an amendment adopted during previous Code adoption cycles. 1613.7 Geological Section is added to improve seismic safety of buildings Topographical constructed on or into hillsides. Due to the local topographical and geological conditions of the sites within the Los Angeles region and their probabilities for earthquakes, this technical amendment is required to address and clarify special needs for buildings constructed on hillside locations. A SEAOSC and Los Angeles City Joint Task Force investigated the performance of hillside building failures after the Northridge earthquake. Numerous hillside failures resulted in loss of life and millions of dollars in damage. These criteria were developed to minimize the damage to these structures and have been in use by both the City and County of Los Angeles for several years with much success. This amendment is a continuation of an amendment.adopted during previous Code adoption cycles. 1704.5 Geological The language in Sections 1704.5 of the California Building Code permits the owner to employ any registered design professional to perform structural observations with minimum guidelines. However, it is important to recognize that the registered design professional responsible for the structural design has thorough knowledge of the building he /she designed. By requiring the registered design HOA.991471.2 144 Code Condition Explanation of Amendment Section professional responsible for the structural design or their designee who were involved with the design to observe the construction, the quality of the observation for major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased. Additional requirements are provided to help clarify the role and duties of the structural observer and the method of reporting and correcting observed deficiencies to the building official. This amendment is a continuation of an amendment adopted during previous Code adoption cycles; and is necessary due to the increased risk of significant earthquakes in the County. 1704.5.1 Geological With the higher seismic demand placed on buildings and structures in this region, the language in Sections 1704.5.1 Item 3 of the California Building Code would permit many low -rise buildings and structures with complex structural elements to be constructed without the benefit of a structural observation. By requiring a registered design professional to observe the construction, the quality of the observation for major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased. An exception is provided to permit simple structures and buildings to be excluded. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in County. 1705.3 and Geological Results from studies after the 1994 Northridge Earthquake Table indicated that a significant portion of the damages were 1705.3 attributable to lack of quality control during construction resulting in poor performance of the building or structure. Therefore, the amendment restricts the exceptions to the requirement for special inspection. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 1705.11 Geological In Southern California, very few detached one- or two - family dwellings not exceeding two stories above grade plane are built as "box -type" structures, specially for those HOA.991471.2 145 Code Condition Explanation of Amendment Section in hillside areas and near the oceanfront. Many with steel moment frames or braced frames, and or cantilevered columns can still be shown as "regular" structures by calculations. With the higher seismic demand placed on buildings and structures in this region, the language in Sections 1705.11 Item 3 of the California Building Code would permit many detached one- or two- family dwellings not exceeding two stories above grade plane with complex structural elements to be constructed without the benefit of special inspections. By requiring special inspections, the quality of major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased. The exception should only be allowed for detached one- or two- family dwellings not exceeding two stories above grade plane assigned to Seismic Design category A, B, and C. 1807.1.4 Climatic No substantiating data has been provided to show that a Geological wood foundation is effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effect of constant moisture in the soil and wood - destroying organisms. Wood retaining walls, when they are not properly treated and protected against deterioration, have performed very poorly and have led to slope failures. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic events and wet applications. The proposed amendment takes the necessary precautionary steps to reduce or eliminate potential problems that may result by using wood foundations that experience relatively rapid decay due to the fact that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood - destroying organisms. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 1807.1.6 Geological With the higher seismic demand placed on buildings and HOA.991471.2 146 Code Condition Explanation of Amendment Section structures in this region, it is deemed necessary to take precautionary steps to reduce or eliminate potential problems that may result by following prescriptive design provisions that do not take into consideration the surrounding environment. Plain concrete performs poorly in withstanding the cyclic forces resulting from seismic events. In addition, no substantiating data has been provided to.show that under - reinforced foundation walls are effective in resisting seismic loads and may potentially lead to a higher risk of failure. It is important that the benefit and expertise of a registered design professional be obtained to properly analyze the structure and take these issues into consideration. This amendment is a continuation of an amendment adopted during previous Code adoption cycles. 1809.3 Geological With the higher seismic demand placed on buildings and structures in this region, it is deemed necessary to take precautionary steps to reduce or eliminate potential problems that may result for under - reinforced footings located on sloped surfaces. Requiring minimum reinforcement for stepped footings is intended to address the problem of poor performance of plain or under - reinforced footings during a seismic event. This amendment is a continuation of an amendment adopted during previous Code adoption cycles. 1809.7 and Geological No substantiating data has been provided to show that Table under - reinforced footings are effective in resisting seismic 1809.7 loads and may potentially lead to a higher risk of failure. Therefore, this amendment requires minimum reinforcement in continuous footings to address the problem of poor performance of plain or under - reinforced footings during a seismic event. With the higher seismic demand placed on buildings and structures in this region, it is deemed necessary to take precautionary steps to reduce or eliminate potential problems that may result by following prescriptive design provisions for footings that do not take into consideration the surrounding environment. It was important that the benefit and expertise of a registered design professional be obtained to properly analyze the structure and take these factors into consideration. This amendment reflects the HOA.991471.2 147 Code Condition Explanation of Amendment Section recommendations by the SEAOSC and the Los Angeles City Joint Task Force that investigated the poor performance observed in the 1994 Northridge Earthquake. This amendment is a continuation of an amendment adopted during previous Code adoption cycles. 1809.12 Climatic No substantiating data has been provided to show that Geological timber footings are effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effects of constant moisture in the soil and wood - destroying organisms. Timber footings, when they are not properly treated and protected against deterioration, have performed very poorly. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic events and wet applications. The proposed amendment takes the necessary precautionary steps to reduce or eliminate potential problems that may result by using timber footings that experience relatively rapid decay due to the fact that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood- destroying organisms. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 1905.1 and Geological The design provision for wall pier detailing was originally 1905.1.3 introduced by SEAOC in 1987 to legacy Uniform Building Code (UBC) and was included in the 1988 UBC through the 1997 UBC (2002 CBC). The wall pier detailing provision prescribed under Section 1905.1.4 was intended for high seismic zones equivalent to current Seismic Design Category D, E, or F. Section 1905.1.3 was added as a complement of wall pier detailing in Seismic Design Category C (formerly seismic zones 2A and 2B under the legacy model code). ACI 318 Commentary R 21.1.1 emphasized "it is essential that structures assigned to higher Seismic Design Categories possess a higher degree of toughness," and further encourages p ractitioners to usespecial structural walls stems in HoA.991471z 148 Code Section Condition Explanation of Amendment regions of high seismic risk. ASCE 7 Table 12.2 -1 permits intermediate precast structural wall system in Seismic Design Category D, E, or F: Current Section 1905.1.3 is not limited to just structures assigned to Seismic Design Category C. The required shear strength under 21.3.3, referenced in Section 21.4.6, is based on V under either nominal moment strength or two times the code prescribed earthquake force. The required shear strength in 21.6.5.1, referenced in Section 21.9.8.2 (IBC 1905.1.4), is based on the probable shear strength, V under the probable moment strength, M In addition, the spacing of required shear reinforcement is 8 inches on center under current Section 21.4.6 instead of 6 inches on center with seismic hooks at both ends under Section 21.9.8.2. Requirement of wall pier under Section 21.9.8.2 would enhance better ductility. The current practice in commercial buildings constructed using precast panel wall systems is to have large window and door openings and /or narrow wall piers. Wall panels varying up to three stories high with openings resembles a wall frame which is not currently recognized under any of the defined seismic -force resisting systems other than consideration of structural wall systems. Conformance to special structural wall system design and detailing of wall piers ensures minimum life safety performance in resisting earthquake forces for structures in Seismic Design Category D, E, or F. The modification separates wall piers designed for structures assigned to Seismic Design Category C from those assigned to Seismic Design Category D, E, or F. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 1905.1.8 Geological This amendment requires minimum reinforcement in continuous footings to address the problem of poor performance of plain or under - reinforced footings during a seismic event. This amendment reflects the recommendations by the SEAOSC and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. This amendment is a continuation of an amendment HOA.991471.2 - 149 Code Condition Explanation of Amendment Section adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 1905.1.10 Geological This amendment is intended to carry over critical through provisions for the design of concrete columns in moment 1905.1.12 frames from the UBC. Increased confinement is critical to the integrity of such columns and these modifications ensure that it is provided when certain thresholds are exceeded. In addition, this amendment carries over from the UBC a critical provision for the design of concrete shear walls. It essentially limits the use of very highly gravity- loaded walls from being included in the seismic load resisting system, since their failure could have catastrophic effect on the building. Furthermore, this amendment was incorporated in the Code based on observations from the 1994 Northridge Earthquake. Rebar placed in very thin concrete topping slabs has been observed in some instances to have popped out of the slab due to insufficient concrete coverage. This modification ensures that critical boundary and collector rebars are placed insufficiently thick.slabs to prevent buckling of such reinforcements. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 2304.9.1 Geological Due to the high geologic activities in the Southern and Table California area and the expected higher level of 2304.9.1 performance on buildings and structures, this proposed local amendment limits the use of staple fasteners in resisting or transferring seismic forces. In September 2007, limited cyclic testing data was provided to the ICC Los Angeles Chapter Structural Code Committee showing that stapled wood structural shear panels do not exhibit the same behavior as nailed wood structural shear panels. The test results of stapled wood structural shear panels appeared much lower in strength and drift than nailed wood structural shear panel test results. Therefore, the use of staples as fasteners to resist or transfer seismic forces shall not be permitted without being substantiated by cyclic testing. This amendment is a continuation of a similar amendment adopted during previous Code HOA.991471.2 150 Code Condition Explanation of Amendment Section adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 2304.11.7 Climatic No substantiating data has been provided to show that Geological wood used in retaining or crib walls is effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effect of constant moisture in the soil and wood- destroying organisms. Wood used in retaining or crib walls, when it is not properly treated and protected against deterioration, has performed very poorly. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic events and wet applications. The proposed amendment takes the necessary precautionary steps to reduce or eliminate potential problems that may result by using wood in retaining or crib walls that experience relatively rapid decay due to the fact that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood- destroying organisms. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 2305.4 Geological The overdriving of nails into the structural wood panels still remains a concern when pneumatic nail guns are used for wood structural panel shear wall nailing. Box nails were observed to cause massive and multiple failures of the typical 3/8 -inch thick plywood during the 1994 Northridge Earthquake. The use of clipped head nails continues to be restricted from use in wood structural panel shear walls where the minimum nail head size must be maintained in order to minimize nails from pulling through sheathing materials. Clipped or mechanically driven nails used in wood structural panel shear wall construction were found to perform much worse in previous wood structural panel shear wall testing done at the University of California Irvine. The existing test results indicated that, under cyclic loading, the wood structural panel shear walls were less energy absorbent and less HOA.9914712 151 Code Condition Explanation of Amendment Section ductile. The panels reached ultimate load capacity and failed at substantially less lateral deflection than those using same size hand - driven nails. This amendment reflects the recommendations by the SEAOSC and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 2305.5 Geological Many of the hold -down connectors currently in use do not have any acceptance report based on dynamic testing protocol. This amendment continues to limit the allowable capacity to 75% of the acceptance report value to provide an additional factor of safety for statically tested anchorage devices. Cyclic forces imparted on buildings and structures by seismic activity cause more damage than equivalent forces which are applied in a static manner. Steel plate washers will reduce the additional damage which can result when hold -down connectors are fastened to wood framing members. This amendment reflects the recommendations by the SEAOSC and the Los Angeles City Joint Task Force that investigated the poor performance observed in the 1994 Northridge Earthquake. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 2306.2 Geological The SEAOSC and the Los Angeles City Joint Task Force that investigated the damages to buildings and structures during the 1994 Northridge Earthquake recommended reducing allowable shear values in wood structural panel shear walls or diaphragms that were not substantiated by cyclic testing. That recommendation was consistent with a report to the Governor from the Seismic Safety Commission of the State of California recommending that code requirements be "more thoroughly substantiated with testing." The allowable shear values for wood structural panel shear walls or diaphragms fastened with staples are based on monotonic testing and do not take into HOA.991471.2 152 Code Section Condition Explanation of Amendment consideration that earthquake forces load shear wall or diaphragm in a repeating and fully reversible manner. In September 2007, limited cyclic testing was conducted by a private engineering firm to determine if wood structural panels fastened with staples would exhibit the same behavior as wood structural panels fastened with common nails. The test result revealed that wood structural panels fastened with staples appeared to be much lower in strength and stiffness than wood structural panels fastened with common nails. It was recommended that the use of staples as fasteners for wood structural panel shear walls or diaphragms not be permitted to resist seismic forces in structures assigned to Seismic Design Category D, E and F unless it can be substantiated by cyclic testing. Furthermore, the cities and unincorporated areas within the Los Angeles region have taken extra measures to maintain the structural integrity of the framing of shear walls and diaphragms designed for high levels of seismic forces by requiring wood sheathing be applied directly over the framing members and prohibiting the use of panels placed over gypsum sheathing. This amendment is intended to, prevent the undesirable performance of nails when gypsum board softens due to cyclic earthquake displacements and the nail ultimately does not have any engagement in a solid material within the thickness of the gypsum board. This amendment continues the previous amendment adopted during the 2007 Code adoption cycle. 2306.3 and Geological The SEAOSC and the Los Angeles City Joint Task Force 2307.2 that investigated the damages to buildings and structures during the 1994 Northridge Earthquake recommended reducing allowable shear values in wood structural panel shear walls or diaphragms that were not substantiated by cyclic testing. That recommendation was consistent with a report to the Governor from the Seismic Safety Commission of the State of California recommending that code requirements be "more thoroughly substantiated with testing." The allowable shear values for wood structural panel shear walls or diaphragms fastened with stapled nails are based on monotonic testing and do not take into consideration that earthquake forces load shear wall or HO&991471.2 153 Code Section Condition Explanation of Amendment diaphragm in a repeating and fully reversible manner. In September 2007, limited cyclic testing was conducted by a private engineering firm to determine if wood structural panels fastened with stapled nails would exhibit the same behavior as wood structural panels fastened with common nails.

This amendment continues the previous amendment adopted during the 2007 Code adoption cycle, and is necessary due to the increased risk of significant earthquakes in the County. 2308.3.4 Geological With the higher seismic demand placed on buildings and structures in this region, interior walls can easily be called upon to resist over half of the seismic loading imposed on simple buildings or structures. Without a continuous foundation to support the braced wall line, seismic loads would be transferred through other elements such as non- structural concrete slab floors, wood floors, etc. The purpose of this amendment is to limit the use of the exception to structures assigned to Seismic Design Category A, B or C where lower seismic demands are expected. Requiring interior braced walls be supported by continuous foundations is intended to reduce or eliminate the poor performance of buildings or structures. This HOA.991471.2 154- Code Section Condition Explanation of Amendment amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 2308.9.3.1, Geological The SEAOSC and the Los Angeles City Joint Task Force 2308.9.3.2 that investigated the damages to buildings and structures and Figure during the 1994 Northridge Earthquake recommended 2308.9.3.2 reducing allowable shear values in wood. structural panel shear walls or diaphragms that were not substantiated by cyclic testing.

Table Geological This amendment specifies minimum sheathing thickness 2308.12.4 and nail size and spacing so as to provide a uniform standard of construction for designers and buildings to follow. This is intended to improve the performance level of buildings and structures that are subject to the higher seismic demands placed on buildings or structure in this region. This proposed amendment reflects the recommendations by the SEAOSC and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. This amendment is a continuation of an amendment adopted during previous Code adoption cycles, and is necessary due to the increased risk of significant earthquakes in the County. 2308.12.5 Geological Due to the high geologic activities in the Southern California area and the expected higher level of performance on buildings and structures, this amendment limits the use of staple fasteners in resisting or transferring seismic forces.

For chimneys up to 40 inches (1016 mm) wide, four No. 4 continuous vertical bars adequately anchored into the concrete foundation shall be placed between wythes of solid masonry or within the cells of hollow unit masonry and grouted in accordance with Section R609. Grout shall be prevented from bonding with the flue liner so that the flue liner is free to move with thermal expansion. For chimneys more than 40 inches (10 16 mm) wide, two additional No. 4 vertical bars adequately anchored into the concrete foundation shall be provided for each additional flue incorporated into the chimney or for each additional 40 inches (1016 mm) in width or fraction thereof. SECTION 49. The provisions of this ordinance contain various changes, modifications, and additions to the 2013 Edition of the California Residential Code. Some of these changes are administrative in nature in that they do not constitute changes or modifications to requirements contained in the building standards published in the California Building Standards Code. Pursuant to California Health and Safety Code sections 17958.5, 17958.7, and 18941.5, the Board of Supervisors hereby expressly finds that all of the changes and modifications to requirements contained in the building standards published in the California Building Standards Code contained in this ordinance, which are not administrative in nature, are reasonably necessary because of local climatic, geological, or topographical conditions in the County of Los Angeles as more particularly described in the table set forth below. HOA.1009141.1 33 Code Section Condition Explanation of Amendment R301.1.3.2 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. After the 1994 Northridge Earthquake, the Wood Frame Construction Joint Task Force recommended that the quality of wood frame construction needs to be greatly improved. One such recommendation identified by the Task Force is to improve the quality and organization of structural plans prepared by the engineer or architect so that plan examiners, building inspectors, contractors, and special inspectors may logically follow and construct the presentation of the seismic force - resisting systems in the construction documents. For buildings or structures located in Seismic Design Category Do, D1, DZ, or E that are subject to a greater level of seismic forces, the requirement to have a California licensed architect or engineer prepare the construction documents is intended to minimize or reduce structural deficiencies that may cause excessive damage or injuries in wood frame buildings.. Structural deficiencies such as plan and vertical irregularities, improper shear transfer of the seismic force - resisting system, missed details or connections important to the structural system, and the improper application of the prescriptive requirements of the California Residential Code can be readily addressed by a registered design p rofessional. R301.1.4 Geological This technical amendment is for buildings constructed on Topographical hillsides. Due to the local topographical and geological conditions of the sites within the greater Los Angeles region and their susceptibility to earthquakes, this amendment is required to address and clarify special . needs for buildings constructed on hillside locations. A joint Structural Engineers Association of Southern California (SEAOSC) and Los Angeles City Joint Task Force investigated the performance of hillside building failures after the Northridge earthquake. Numerous hillside failures resulted in loss of life and millions of dollars in damage. These criteria were developed to minimize the damage to these structures and have been in use by the City and County of Los Angeles for several years. R301.2.2.2.5 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. Due to the high geologic activities in the Southern HOA.1009141.1 34 Code Section Condition Explanation of Amendment California area and the expected higher level of performance on buildings and structures, this local amendment limits the type of irregular conditions as specified in the 2013 California Residential Code. Such limitations are recommended to reduce structural damages in the event of an earthquake. The cities and County of the Los Angeles region have taken extra measures to maintain the structural integrity of the framing of the shear walls and all associated elements when designed for high levels of seismic loads. R301.2.2.3.8 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. Due to the high geologic activities in the Southern California area and the expected higher level of performance on buildings and structures, this local amendment limits the potential anchorage and supporting frame failure resulting from additional weight. There is no limitation for weight of mechanical and plumbing fixtures and equipment in the International Residential Code. Requirements from ASCE 7 and the International Building Code would permit equipment weighing up to 400 lbs. when mounted at 4 feet or less above the floor or attic level without engineering design. Where equipment exceeds this requirement, it is the intent of this proposed amendment that a registered design professional be required to analyze if the floor support is adequate and structurally sound. Table R302.1(2) Climatic This amendment will not allow unprotected openings (openings that do not resist the spread of fire) to be in the exterior wall of a residential building that is located on a property line. This amendment is necessary due to local climatic conditions. During the hot, dry weather conditions of late summer in combination with the Santa Ana winds creates an extreme fire danger. Residential buildings with unprotected openings located on a property line will allow the spread of fire from the inside of the building to adjacent properties and likewise from exterior properties to the interior of the building. R327.1.1 Climatic Clarifies the application of Chapter R327 to include additions, alterations, and /or relocated buildings. Many areas of the County have been designated as Fire Hazard Severity Zones due to low humidity, strong winds, and d HOA.1009141.1 35 Code Section Condition Explanation of Amendment vegetation. Additions, alterations, and /or relocated buildings have the same fire risk as new buildings. R327.1.3 Climatic Clarifies the application of Chapter R327 to include additions, alterations, and /or relocated buildings. Many areas of the County have been designated as Fire Hazard Severity Zones due to the increased risk of fire caused by low humidity, strong winds, and dry vegetation.

R327.5.2 Climatic Disallows the use of wood- shingle/wood -shake roofs and requires the use of Class A roof covering due to the increased risk of fire in the County caused by low humidity, strong winds, and dry vegetation in High Fire Severity Zones. R401.1 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. Wood foundations, even those that are preservative - treated, encounter a higher risk of deterioration when contacting the adjacent ground. The required seismic anchorage and transfer of lateral forces into the foundation system necessary for 2 -story structures and foundation . walls could become compromised at varying states of wood decay. In addition, global structure overturning moment and sliding resistance is reduced when utilizing HOA.1009141.1 36 Code Section Condition Explanation of Amendment wood foundations as opposed to conventional concrete or masonry systems. However, non - occupied, single -story storage structures pose significantly less risk to human safety and should be able to utilize the wood foundation g uidelines specified in this Chapter. R403.1.2 Climatic Los Angeles County is prone to seismic activity due to the R403.1.3 Geological existence of active faults in the Southern California area. R403.1.5 These proposed amendments require minimum Figure R403.1.5 reinforcement in continuous footings and stepped footings to address the problem of poor performance of plain or under- reinforced footings during a seismic event. These amendments reflect the recommendations by SEAOSC and the Los Angeles City Joint Task Force that investigated the poor performance observed in the 1994 Northridge Earthquake. These proposed amendments are a continuation of an amendment adopted during previous code adoption cycles. Interior walls can easily be called upon to resist over half of the seismic loading imposed on simple buildings or structures. Without a continuous foundation to support the braced wall line seismic loads would be transferred through other elements such as non- structural concrete slab floors, wood floors, etc. Requiring interior braced walls be supported by continuous foundations is intended to reduce or eliminate the poor performance of buildings or structures. R404.2 Climatic No substantiating data has been provided to show that Geological wood foundations are effective in supporting structures and buildings during a seismic event while being subject to deterioration caused by presence of water in the soil as well as other materials detrimental to wood foundations. Wood foundations, when they are not properly treated and' protected against deterioration, have performed very poorly and have led to slope failures. Most contractors are typically accustomed to construction in dry weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic events and wet applications. With the higher seismic demand placed on buildings and structures in this region, coupled with the dryer weather conditions here as oppose to the northern and eastern part of the country, it is the intent of this p roposal to take the necessary precautionary steps to HOA.1009141.1 37 Code Section Condition Explanation of Amendment reduce or eliminate potential problems that may result from the use of wood footings and foundations that does not take into consideration the conditions of this surrounding environment. R501.1 Geological Due to the high geologic activities in the Southern California area and the expected higher level of performance on buildings and structures, this local amendment limits the potential anchorage and supporting frame failure resulting from additional weight. There is no limitation for weight of mechanical and plumbing fixtures and equipment in the International Residential Code. Requirements from ASCE 7 and the International Building Code would permit equipment weighing up to 400 lbs. when mounted at 4 feet or less above the floor or attic level without engineering design. Where equipment exceeds this requirement, it is the intent of this proposed amendment that a registered design professional be required to analyze if the floor support is adequate and structurally sound. R503.2.4 Geological Section R502.10 of the Code does not provide any prescriptive criteria. to limit the maximum floor opening size nor does Section R503 provide any details to address the issue of shear transfer near larger floor openings. With the higher seismic demand placed on buildings and structures in this region, it is important to ensure that a complete load path is provided to reduce or eliminate potential damages caused by seismic forces. Requiring blocking with metal ties around larger floor openings and limiting opening size is consistent with the requirements of Section R301.2.2.2.5. R602.3.2 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. The cities and County of the Los Angeles region have taken extra measures to maintain the structural integrity of the framing of the shear walls when designed for high levels of seismic loads by eliminating single top plate construction. The performance of modern day braced wall panel construction is directly related to an adequate load path extending from the roof diaphragm to the foundation system. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. HOA.1009141.1 38 Code Section Condition Explanation of Amendment Table R602.3(1) Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. In September 2007, limited cyclic testing data was provided to the ICC Los Angeles Chapter Structural Code Committee showing that stapled wood structural shear panels do not exhibit the same behavior as the nailed . wood structural shear panels. As a matter of fact, the test results of the stapled wood structural shear panels appeared much lower in strength and drift than the nailed wood structural shear panel test results. Therefore, the .use of staples as fasteners for shear walls sheathed with other materials shall not be permitted without being substantiated by cyclic testing. This proposed amendment is a continuation of an\ amendment adopted during the p revious Code adoption cycle. Table R602.3(2) Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area.

Therefore, the use of staples as fasteners for shear walls sheathed with other materials shall not be permitted without being substantiated by cyclic testing. This proposed amendment is a continuation of an amendment adopted during the p revious Code adoption cycle. Table Geological Due to the high geologic activities in the Southern R602.10.3(3) California area and the expected higher level of performance on buildings and structures, this local amendment continues to reduce /eliminate the allowable shear values for shear walls sheathed with lath, plaster or gypsum board. The poor performance of such shear walls sheathed with other materials in the 1994 Northridge Earthquake was investigated by SEAOSC and the Los Angeles City Joint Task Force. The cities and County of the Los Angeles region have taken extra measures to maintain the structural integrity of the framing of the shear walls when designed for high levels of seismic loads. HOA.1009141.1 39 Code Section Condition Explanation of Amendment Table Geological 3/8" thick 3 ply - plywood shear walls experienced many R602.10.4 failures during the Northridge Earthquake. This proposed amendment specifies minimum WSP sheathing thickness and nail size and spacing so as to provide a uniform standard of construction for designers and buildings to follow. This is intended to improve the performance level of buildings and structures that are subject to the higher seismic demands placed on buildings or structure in this region. This proposed amendment reflects the recommendations by SEAOSC and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. In September 2007, cyclic testing data was provided to the structural code committee showing that stapled wood structural shear panels do not exhibit the same behavior as the nailed wood structural shear panels. In addition, the test results of the stapled wood structural shear panels appeared much lower in strength and drift than the nailed wood structural shear panel test results. This proposed amendment is a continuation of an amendment adopted during the previous Code adoption cycle. Table Geological Los Angeles County is prone to seismic activity due to the R602.10.5 existence of active faults in the Southern California area. The poor performance of such shear walls sheathed in the 1994 Northridge Earthquake was investigated by SEAOSC and the Los Angeles City Joint Task Force. The cities and County of the Los Angeles region have taken extra measures to maintain the structural integrity with respect to the "maximum shear wall aspect ratios" of the framing of the shear walls when designed for high levels of seismic loads. This proposed amendment is consistent with the shear wall aspect ratio provision of Section 4.3.4 of AF &PA SDPWS -2008. Figure Geological 3/8" thick 3 ply - plywood shear walls experienced many R602.10.6.1 failures during the Northridge Earthquake.

The cities and County of the Los Angeles region have taken extra measures to maintain the structural integrity of the framing of the shear walls when designed for high levels of seismic loads. Box nails were observed to cause massive and multiple failures of the typical 3/8 -inch thick plywood during the Northridge Earthquake. The proposal to change the minimum lap splice requirement is consistent with Section 12.16.1 of ACI 318 -11.

The proposal in which "washers shall be a minimum of 0.229 inch by 3 inches by 3 inches in size" is consistent with Section R602.11.1 of the California Residential Code and Section 2308.12.8 of the California Building Code. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. R602.10.9.1 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. The performance of modern day braced wall panel HOA.1009141.1 41 Code Section Condition Explanation of Amendment construction is directly related to an adequate load path extending from the roof diaphragm to the foundation system. Interior braced wall panels, therefore, are also directly dependent upon the adequacy of the foundation system. In addition, the proposed amendment for Section R403.1.2 specifies that all exterior walls and required interior braced wall panels in buildings shall be supported with continuous footings. R606.2.4 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. The addition of the word "or" will prevent the use of unreinforced parapets in Seismic Design Category D D or D 2 , or on townhouses in Seismic Design Category C. R606.12.2.2.3 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. Reinforcement using longitudinal wires for buildings and structures located in high seismic areas are not as ductile as deformed rebar. Having vertical reinforcement closer to the ends of masonry walls help to improve the seismic p erformance of masonry buildings and structures. R803.2.4 Geological Section R802 of the Code does not provide any prescriptive criteria to limit the maximum size of roof openings, nor does Section R803 provide any details to address the issue of shear transfer near larger roof openings. With the higher seismic demand placed on buildings and structures in this region, it is important to ensure that a complete load path is provided to reduce or eliminate potential damage caused by seismic forces. Requiring blocking with metal ties around larger roof openings and limiting the size of openings is consistent with the requirements of Section R301.2.2.2.5. R1001,3.1 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. The performance of fireplaces /chimneys without anchorage to the foundation has been observed to be inadequate during major earthquakes. The lack of anchorage to the foundation results in overturn or displacement. SECTION 49. This ordinance shall become operative on January 1, 2014.

SECTION 27. This ordinance shall become operative on January 1, 2014. IrITLE312013CSCCl HOA.996319.2 - 20 ATTACHMENT D Reserved CHAPTER' 2013 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM RECOMMENDED TECHNICAL AMENDMENTS TO THE 2013 EDITION OF THE CALIFORNIA BUILDING CODE, CALIFORNIA RESIDENTIAL CODE, AND CALIFORNIA GREEN BUILDING STANDARDS CODE Final Version: September 5, 2013 PREPARED BY: ICC LOS ANGELES BASIN CHAPTER'S STRUCTURAL CODE COMMITTEE GREEN BUILDING STANDARDS CODE COMMITTEE FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM UN41_Cyd In 1957 our founding members established one of the earliest chapters of the International Conference of Building Officials. Today the Chapter has grown to over eighty -nine Southern California jurisdictions, plus consulting firms and other members of the construction industry. ICBO merged with two other building official organizations to create the International Code Council. The Los Angeles Basin Chapter officially became an ICC Chapter in December 2002. The Los Angeles Basin Chapter has been very active throughout the years in leading an effort to create uniformity of building codes and regulations in the greater Los Angeles region as well as addressing policy issues of interest to building officials and the construction industry. One such effort to promote uniformity of building regulations is through the Los Angeles Regional Uniform Code Program ( LARUCP). The LARUCP program began in July 1999 with the purpose of developing uniform interpretations and handouts to serve as guidelines for building officials, contractors, engineers and architects in the consistent application of the codes. The mission of this program was to minimize the number of, and to develop uniformity in local technical amendments to the California codes for adoption by jurisdictions in the greater Los Angeles region. Leading the efforts to creating uniformity of building codes and regulations within the region are the dedicated members of the Los Angeles County Building and Safety Division, City of Los Angeles Department of Building and Safety, City of Long Beach Building and Safety Bureau, and other jurisdictional members in the greater Los Angeles region. Through the coordination of the ICC Los Angeles Basin Chapter's Structural Code Committee and Green Building Standards Committee, the following regulatory streamlining tasks to be completed are: 1. Create uniformity of building, plumbing, mechanical, electrical, energy efficiency and green codes that can be adopted in most of the jurisdictions in the greater Los Angeles region. 2. Reduces the total number of local technical amendments to the model code in the greater Los Angeles region. 3. Received support from most, if not all, of the 89 jurisdictions in the greater Los Angeles region. 4. Obtain active participation from a majority of the jurisdictions in the greater Los Angeles region in formulating and implementing this program. 5. With construction valuation of over $5 billion in the region, conservatively assuming that this program produces a 1 % construction cost savings, achieve an estimated cost saving of $50 million per year in the greater Los Angeles region. DISCUSSION Sections 13145.3, 17922, 17958 and 18941.5 of the California Health and Safety Code requires that the latest California Building Standards Codes apply to local construction 180 days after they become effective at the State level. The California Building Standards Commission has adopted the 2013 Edition of the California Building Code, California Residential Code, and California Green Building Standards Code. State Law requires that these Codes become effective at the local level on January 1, 2014. Sections 17958.5 and 17958.7 of the California Health and Safety Code requires that local amendments to the California Building Standards Codes and other regulations, including but not limited to, green building standards, be enacted only when an express finding is made that such modifications or changes are reasonably necessary because of local climatic, geological or topographical conditions. 2013 LARUCP Recommended Technical Amendments Page 2 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM The ICC Los Angeles Basin Chapter's Structural Committee and Green Building Standards Committee are recommending that the 2013 Edition of the LARUCP Recommended Amendments contained in this document, some of which continues amendments enacted during the previous code adoption cycle, be considered for local adoption for the following reasons: To protect the community within the greater Los Angeles region from a vast array of fault systems capable of producing major earthquakes and /or climate systems capable of producing major winds, fire and rain related disaster. 2. To ensure and encourage energy efficiency and sustainable practices are incorporated into building designs and constructions. The 2013 Edition of the LARUCP Recommended Amendments have been widely circulated and discussed over the past several months with various local jurisdictional members, SEAOSC Building Code Committee, design professionals in the construction industry, and other interested groups or individuals. The proposed code language along with the reasons and findings are detailed in this document for each of the recommended technical amendments to the California Building Standards Code. STATEMENT ON USE OF DOCUMENT The primary purpose of the ICC Los Angeles Basin Chapter's Committees is to serve and benefit its members.

Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 15 -01. Section 1507.3.1 of the 2013 Edition of the California Building Code is amended to read as follows: 1507.3.1 Deck requirements. Concrete and clay tile shall be installed only over solid she or spaced structural sheathing boards. RATIONALE Section 1507.3.1 is amended to require concrete and clay tiles to be installed only over solid structural sheathing boards. The change is necessary because there were numerous observations of tile roofs pulling away from wood framed buildings following the 1994 Northridge Earthquake. The SEAOSC /LA City Post Northridge Earthquake committee findings indicated significant problems with tile roofs was due to inadequate design and /or construction. Therefore, the amendment is needed to minimize such occurrences in the event of future significant earthquakes. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake, the 1987 Whittier Narrows Earthquake, the 1971 San Fernando Earthquake and the 1933 Long Beach Earthquake. This amendment will reduce the failure of concrete and clay tile roofs during a significant earthquake and is in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 11 of 126 2013 Edition of the California Building Code Final Version: 9/512013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 16 -01. Section 1613.6 is added to Chapter 16 of the 2013 Edition of the California Building Code to read as follows: 1613.6 ASCE 7. 12.12.3 Modify ASCE 7 Equation 12.12 -1 of Section 12.12.3 to read as follows: SM = C d ,5 .. (12.12 -1) RATIONALE: The inclusion of the importance factor in this equation has the unintended consequence of reducing the minimum seismic separation distance for important facilities such as hospitals, schools, police and fire stations from adjoining structures. The proposal to omit the importance factor from Equation 12.12 -1 will ensure that a safe seismic separation distance is provided. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake, the 1987 Whittier Narrows Earthquake, the 1971 San Fernando Earthquake and the 1933 Long Beach Earthquake. The proposed modification to omit the importance factor in the equation ensures that a safe seismic separation distance is maintained for important facilities from adjoining structures and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 12 of 126 2013 Edition of the California Building Code Final Version: 9/512013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 16 -02. Section 1613.7 is added to Chapter 16 of the 2013 Edition of the California Building Code to read as follows: 1613.7 ASCE 7, 12.2.3.1, Exception 3. Modify ASCE 7 Section 12.2.3.1 Exception 3 to read as follows: 3. Detached one- and two- family dwellings up to two stories in height of light frame construction. RATIONALE: Observed damages to one and two family dwellings of light frame construction after the Northridge Earthquake may have been partially attributed to vertical irregularities common to this type of occupancy and construction. In an effort to improve quality of construction and incorporate lesson learned from studies after the Northridge Earthquake, the proposed modification to ASCE 7 -10 Section 122.3.1 Exception 3 by limiting the number of stories and height of the structure to two stories will significantly minimize the impact of vertical irregularities and concentration of inelastic behavior from mixed structural systems. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake. The proposed modification to limit mixed structural system to two stories is intended to improve quality of construction by reducing potential damages that may result from vertical irregularities of the structural system in buildings subject to high seismic load and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 13 of 126 2013 Edition of the California Building Code Final Version: 9/512013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 16-03. Section 1613.8 is added to Chapter 16 of the 2013 Edition of the California Building Code to read as follows: 1613.8 ASCE 7, Section 12.11.2.2.3. Modify ASCE 7, Section 12.11.2.2.3 to read as follows: 12.11.2.2.3 Wood Diaphragms. In wood diaphragms, the continuous ties shall be in addition to the diaphragm sheathing. Anchorage shall not be accomplished by use of toe nails or nails subject to withdrawal nor shall wood ledgers or framing be used in cross -grain bending or cross -grain tension. The diaphragm sheathing shall not be considered effective as providing ties or struts required by this section. For structures assigned to Seismic Design Category D E or F wood diaphragms supporting concrete or masonry walls shall comply with the following: 1. The spacing of continuous ties shall not exceed 40 feet. Added chords of diaphragms may be used to form subdiaphragms to transmit the anchorage forces to the main continuous crossties. 2. The maximum diaphragm shear used to determine the depth of the subdiaphragm shall not exceed 75% of the maximum diaphragm shear. RATIONALE: A joint Structural Engineers Association of Southern California (SEAOSC), Los Angeles County and Los Angeles City Task Force investigated the performance of concrete and masonry construction with flexible wood diaphragm failures after the Northridge earthquake. It was concluded at that time that continuous ties are needed at specified spacing to control cross grain tension in the interior of the diaphragm. Additionally, there was a need to limit subdiaphragm allowable shear loads to control combined orthogonal stresses within the diaphragm. Recognizing the importance and need to continue the recommendation made by the task force while taking into consideration the improve performances and standards for diaphragm construction today, this proposal increases the continuous tie spacing limit to 40 ft in lieu of 25 ft and to use 75% of the allowable code diaphragm shear to determine the depth of the sub- diaphragm in lieu of the 300 plf and is deemed appropriate and acceptable. Due to the frequency of this type of failure during the past significant earthquakes, various jurisdictions within the Los Angeles region have taken this additional step to prevent roof or floor diaphragms from pulling away from concrete or masonry walls. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake. The proposed modification to require special anchorage of the diaphragm to the wall and limit the allowable shear will address special needs for concrete and masonry construction with flexible wood diaphragm and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 14 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 16 -04.

RATIONALE: Due to the difficulty of fire suppression vehicles accessing winding and narrow hillside properties and the probabilities for future earthquakes in the Los Angeles region, this technical amendment is required to address the special needs for buildings constructed on hillside locations. A joint Structural Engineers Association of Southern California (SEAOSC) and both the Los Angeles County and Los Angeles City Task Force investigated the performance of hillside building failures after the Northridge earthquake. Numerous hillside failures resulted in loss of life and millions of dollars in damage. These criteria were developed to minimize the damage to these structures and have been in use by both the City and County of Los Angeles for several years with much success. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: 2013 LARUCP Recommended Technical Amendments Page 20 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM Local Topographical and Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. Additionally, the topography within the Los Angeles region includes significant hillsides with narrow and winding access that makes timely response by fire suppression vehicles challenging and difficult. The proposed modification establishes design parameters to better mitigate and limit property damage that are the results of increased seismic forces which are imparted upon hillside buildings and structures and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 21 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 16 -05. Section 1613.10 is added to Chapter 16 of the 2013 Edition of the California Building Code to read as follows: 1613.10 Suspended Ceilings. Minimum design and installation standards for suspended ceilings shall be determined in accordance with the requirements of Section 2506.2.1 of this Code and this section. 1613.10.1 Scope. This part contains special requirements for suspended ceilings and lighting systems. Provisions of Section 13.5.6 of ASCE 7 -10 shall apply except as modified herein. 1613.10.2 General. The suspended ceilings and lighting systems shall be limited to 6 feet (1828 mm) below the structural deck unless the lateral bracing is designed by a licensed engineer or architect. Sprinkler heads penetrating fire - resistance -rated floor /ceiling or roof /ceiling assemblies shall complV with Section 714 of this Code. 1613.10.4 Special Requirements for Means of Egress. Suspended ceiling assemblies located along means of egress serving an occupant load of 30 or more shall comply with the following provisions. 1613.10.4.1 General. Ceiling suspension systems shall be connected and braced with vertical hangers attached directly to the structural deck along the means of egress serving an occupant load of 30 or more and at lobbies accessory to Group A Occupancies. Spacing of vertical hangers shall not exceed 2 feet (610 mm) on center along the entire length of the suspended ceiling assemblV located along the means of egress or at the lobby. 1613.10.4.2 Assembly Device. All lay -in panels shall be secured to the suspension ceiling assemblV with two hold -down clips minimum for each tile within a 4 -foot (1219 mm) radius of the exit lights and exit signs. 1613.10.4.3 Emergency Systems. Independent supports and braces shall be provided for light _fixtures required for exit illumination. Power supply for exit illumination shall comply with the requirements of Section 1006.3 of this Code. 1613.10.4.4 Supports for Appendage. Separate support from the structural deck shall be provided for all appendages such as light fixtures, air diffusers, exit signs, and similar elements. RATIONALE: The California Building Code has little to no information regarding the safe design and construction requirements for ceiling suspension systems subject to seismic loads. It is through the experience of prior earthquakes, such as the Northridge Earthquake, that this amendment is proposed so as to minimize the amount of bodily and building damage within the spaces in which this type of ceiling will be installed. This proposed amendment complements ASCE 7 -10 Chapter 13 Section 13.5.6.2.2 and the cited reference to ASTM E580. The amended requirements retained herein are a continuation of portions of an amendment adopted during the previous code adoption cycles. 2013 LARUCP Recommended Technical Amendments Page 22 of 126 2013 Edition of the California.

FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM FINDINGS: Local Geological Conditions — The greater Los Angeles /Long Beach region is a densely populated area having buildings constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake. The proposed modification requiring safe design and construction requirements for ceiling suspension systems to resist seismic loads is intended to minimize the amount of damage within a building and therefore need to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 23 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 17 -01. Section 1704.5 of the 2013 Edition of the California Building Code is amended to read as follows: 1704.5 Structural Observations. Where required by the provisions of Section 1704.5.1 or 1704.5.2, the owner shall employ a FegisteFed design pFefessiena structural observer to perform structural observations as defined in Section 1702. The structural observer shall be one of the following individuals: 1. The registered design professional responsible for the structural design, or 2. A registered design professional designated by the registered design professional responsible for the structural design. Prior to the commencement of observations, the structural observer shall submit to the building official a written statement identifying the frequency and extent of structural observations. The owner or owner's representative shall coordinate and call a preconstruction meeting between the structural observer, contractors, affected subcontractors and special inspectors. The structural observer shall preside over the meeting. The purpose of the meeting shall be to identify the major structural elements and connections that affect the vertical and lateral load resisting systems of the structure and to review scheduling of the required observations. A record of the meeting shall be included in the report submitted to the building official. RATIONALE: The language in Section 1704.5 of the California Building Code permits the owner to employ any registered design professional to perform structural observations with minimum guideline. However, it is important to recognize that the registered design professional responsible for the structural design has thorough knowledge of the building he /she designed. By requiring the registered design professional responsible for the structural design or their designee who were involved with the design to observe the construction, the quality of the observation for major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased. Additional requirements are provided to help clarify the role and duties of the structural observer and the method of reporting and correcting observed deficiencies to the building official. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake.

CVG\ I PL /a1 44 With the higher seismic demand placed on buildings and structures in this region, the language in Section 1704.5.1 of the California Building Code would permit many low -rise buildings and structures with complex structural elements to be constructed without the benefit of a structural observation. By requiring a registered design professional to observe the construction, the quality of the observation for major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased. An exception is provided to permit simple structures and buildings to be excluded. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake.

Section 1705.3 of the 2013 Edition of the California Building Code is amended to read as follows: 1705.3 Concrete Construction. The special inspections and verifications for concrete construction shall be as required by this section and Table 1705.3. Exceptions: Special inspection shall not be required for: 1. Isolated spread concrete footings of buildings three stories or less above grade plane that are fully supported on earth or rock where the structural design of the footing is based on a specified compressive strength, fc, no greater than 2.500 pounds per square inch (psi) (17.2 Mpa) regardless of the compressive strength specified in the construction documents or used in the footing construction. 2. Continuous concrete footings supporting walls of buildings three stories or less in height that are fully supported on earth or rock where: 2.1. The footings support walls of light -frame construction; 2.2. The footings are designed in accordance with Table 1805.4.2; or 2.3. The structural design of the footing is based on a specified compressive strength, fc, no greater than 2,500 pounds per square inch (psi) (17.2 Mpa), regardless of the compressive strength specified in the construction documents or used in the footing construction. 3. Nonstructural concrete slabs supported directly on the ground, including prestressed slabs on grade, where the effective prestress in the concrete is less than 150 psi (1.03 Mpa). 54. Concrete patios, driveways and sidewalks, on grade. RATIONALE: Results from studies after the 1994 Northridge Earthquake indicated that a lot of the damage was attributed to a lack of quality control during construction resulting in poor performance of the building or structure. Therefore, the proposed amendment requires special inspection for concrete with a compressive strength greater than 2,500 pounds per square inch. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles.

(Portions of table not shown remain unchanged.) RATIONALE: The requirements for the special inspection of concrete are contained in Table 1705.3, including the installation of anchors in concrete. The table currently references the 2008 Edition of the ACI 318. Appendix D9.2 has been revised in the 2011 Edition of the ACI 318 specifically to address the inspection of concrete anchors, both adhesive and mechanical anchors. Table 1705.3 is being amended to reflect the new provisions in the 2011 Edition of the ACI 318. FINDINGS: Local Administrative Finding — This amendment is necessary for administrative clarification. It does not modify a Building Standards pursuant to Sections 17958 and 18941.5 of the California Health and Safety Code and does not require an express finding to be made pursuant to Sections 17958.5 and 17958.7 of the California Health and Safety Code. This amendment established administrative standards for the effective enforcement of building standards and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 28 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 17 -05. Exception 3 of Section 1705.11 of the 2013 Edition of the California Building Code is amended to read as follows: 1705.11 Special inspections for seismic resistance. Special inspections itemized in Sections 1705.11.1 through 1705.11.8, unless exempted by the exceptions of Section 1704.2, are required for the following: 1. The seismic force - resisting systems in structures assigned to Seismic Design Category C, D, E or F in accordance with Sections 1705.11.1 through 1705.11.3, as applicable. 2. Designated seismic systems in structures assigned to Seismic Design Category C, D, E or F in accordance with Section 1705.11.4. 3. Architectural, mechanical and electrical components in accordance with Sections 1705.11.5 and 1705.11.6. 4. Storage racks in structures assigned to Seismic Design Category D. E or F in accordance with Section 1705.11.7. 5. Seismic isolation systems in accordance with Section 1705.11.8. Exception: Special inspections itemized in Sections 1705.11.1 through 1705.11.8 are not required for structures designed and constructed in accordance with one of the following: 1. The structure consists of light -frame construction; the design spectral response acceleration at short periods, Sp as determined in Section 1613.3.4, does not exceed 0.5; and the building height of the structure does not exceed 35 feet (10 668 mm) 2. The seismic force - resisting system of the structure consists of reinforced masonry or reinforced concrete; the design spectral response acceleration at short periods, Sp as determined in Section 1613.3.4, does not exceed 0.5; and the building height of the structure does not exceed 25 feet (7620 mm) 3. The structure is a detached one- or two- family dwelling not exceeding two stories above grade plane, is not assigned to Seismic Design Category D, E or F and does not have any of the following horizontal or vertical irregularities in accordance with Section 12.3 of ASCE 7: 3.1 Torsional or extreme torsional irregularity. 3.2 Nonparallel systems irregularity. 3.3 Stiffness -soft story or stiffness - extreme soft story irregularity. 3.4 Discontinuity in lateral strength -weak story irregularity. ;7a\ 1 tQP L1I=9 In Southern California, very few detached one- or two- family dwellings not exceeding two stories above grade plane are built as "box -type' structures, especially those in hillside areas and near the oceanfront. Many steel moment frames or braced frames and /or cantilevered columns within buildings can still be shown as "regular' structures by calculations. With the higher seismic demand placed on buildings and structures in this region, the language in Section 1705.11 Exception 3 of the California Building Code would permit many detached one- or two- family dwellings not exceeding two stories above grade plane 2013 LARUCP Recommended Technical Amendments Page 29 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM with complex structural elements to be constructed without the benefit of special inspections. By requiring special inspections, the quality of major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased. The exception should only be allowed for detached one- or two- family dwellings not exceeding two stories above grade plane assigned to Seismic Design category A, B and C. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake. The proposed modification to require special inspections for detached one- or two- family dwellings not exceeding two stories above grade plane assigned to Seismic Design Category D, E and F will help ensure that acceptable standards of workmanship and quality of construction are provided and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 30 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 17 -06. Section 1711.1.1, Section 1711.1.2 and Chapter 35 of the 2013 Edition of the California Building Code are amended to read as follows: 1711.1.1 General. The vertical load- bearing capacity, torsional moment capacity and deflection characteristics of joist hangers shall be determined in accordance with ASTM D 1761 and ASTM D 7147 as specified below using lumber having a specific gravity of 0.49 or greater, but not greater than 0.55, as determined in accordance with AF &PA NDS for the joist and headers. Exception: The joist length shall not be required to exceed 24 inches (610 mm). 1711.1.2 Vertical load capacity for joist hangers. The vertical load- bearing capacity for the joist hanger shall be determined by testing a minimum of three joist hanger assemblies as specified in ASTM D 1761 or ASTM D 7147 If the ultimate vertical load for any one of the tests varies more than 20 percent from the average ultimate vertical load, at least three additional tests shall be conducted. The allowable vertical load- bearing of the joist hanger shall be the lowest value determined from the following: 1. The lowest ultimate vertical load for a single hanger from any test divided by three (where three tests are conducted and each ultimate vertical load does not vary more than 20 percent from the average ultimate vertical load). 2. The average ultimate vertical load for a single hanger from all tests divided by three (where six or more tests are conducted). 3. The average from all tests of the vertical loads that produce a vertical movement of the joist with respect to the header of 1/8 inch (3.2 mm). 4. The sum of the allowable design loads for nails or other fasteners utilized to secure the joist hanger to the wood members and allowable bearing loads that contribute to the capacity of the hanger. 5. The allowable design load for the wood members forming the connection. Amend the Reference Standards in Chapter 35 for ASTM as follows: ID 1761 06 D 1761- 88(2000) e1 Test Method for Mechanical Fasteners in Wood 1711.1.1 1711.1.2 1711.1.3 D 7147 -05 Standard Specification for Testing and Establishing 1711.1.1 1711.1.2 Allowable Loads of Joist Hangers RATIONALE: ASTM D 1760 -06 contains exactly the same standard test methods as ASTM D 1761 -88 (2000) e1 except for joist hangers. Standard test methods for joist hangers found in former ASTM D 1761 -88 (2000)e1 sections 41 to 50 were removed from ASTM D 1761 -06 due to their inclusion and update in the new standard ASTM D 7147 -05 Standard Specification for Testing and Establishing Allowable Loads of Joist Hangers. Nonetheless, both the 2009 and 2012 editions of the IBC reference ASTM D1761 -2006 for this testing. As a result, testing of joist hangers no longer has a valid reference standard.

It does not modify a Building Standards pursuant to Sections 17958 and 18941.5 of the California Health and Safety 2013 LARUCP Recommended Technical Amendments Page 31 of 126 2013 Edition of the California Building Code Final version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code . FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM Code and does not require an express finding to be made pursuant to Sections 17958.5 and 17958.7 of the California Health and Safety Code. This amendment established administrative standards for the effective enforcement of building standards and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 32 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 18 -01. Section 1807.1.4 of the 2013 Edition of the California Building Code is amended to read as follows: 1807.1.4 Permanent wood foundation systems. Permanent wood foundation systems shall be designed and installed in accordance with AF &PA PWF. Lumber and plywood shall be treated in accordance with AWPA U1 (Commodity Specification A, Use Category 4B and Section 5.2) and shall be identified in accordance with Section 2303.1.8.1. Permanent wood foundation systems shall not be used for structures assigned to Seismic Design Category D. E or F. RATIONALE: No substantiating data has been provided to show that wood foundation systems are effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effects of constant moisture in the soil and wood- destroying organisms. Wood foundation systems not properly treated and protected against deterioration, have performed very poorly and have led to slope failures. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic events and wet applications. The proposed amendment takes the precautionary steps to reduce or eliminate potential problems that may result in using wood foundation systems that experience relatively rapid decay due to the fact that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood - destroying organisms. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Climatic and Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake. In addition, the region is within a climate system capable of producing major winds, fire and rain related disasters, including but not limited to those caused by the Santa Ana winds and El Nino (or La Nina) subtropical -like weather. This region is especially susceptible to more active termite and wood attacking insects and microorganisms. The proposed modification to prohibit the use of wood foundation systems as well as limit prescriptive design provisions in an effort to mitigate potential problems or deficiencies due to the proliferation of wood- destroying organisms and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 33 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 18 -02. Section 1807.1.6 of the 2013 Edition of the California Building Code is amended to read as follows: 1807.1.6 Prescriptive design of concrete and masonry foundation walls. Concrete and masonry foundation walls that are laterally supported at the top and bottom shall be permitted to be designed and constructed in accordance with this section. Prescriptive design of foundation walls shall not be used for structures assigned to Seismic Design Category D E or F. RATIONALE: With the higher seismic demand placed on buildings and structures in this region, it is deemed necessary to take precautionary steps to reduce or eliminate potential problems that may result by following prescriptive design provisions that does not take into consideration the surrounding environment. Plain concrete performs poorly in withstanding the cyclic forces resulting from seismic events. In addition, no substantiating data has been provided to show that under - reinforced foundation walls are effective in resisting seismic loads and may potentially lead to a higher risk of failure. It is important that the benefit and expertise of a registered design professional be obtained to properly analyze the structure and take these issues into consideration. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles.

Section 1809.3 of the 2013 Edition of the California Building Code is amended to read as follows: 1809.3 Stepped footings. The top surface of footings shall be level. The bottom surface of footings shall be permitted to have a slope not exceeding one unit vertical in 10 units horizontal (10- percent slope). Footings shall be stepped where it is necessary to change the elevation of the top surface of the footing or where the surface of the ground slopes more than one unit vertical in 10 units horizontal (10- percent slope). SIMPED FOUNDATIONS, FIGURE 1809.3 STEPPED FOOTING RATIONALE: With the higher seismic demand placed on buildings and structures in this region, precautionary steps are proposed to reduce or eliminate potential problems that may result for under reinforced footings located on sloped surfaces. Requiring minimum reinforcement for stepped footings is intended to address the problem of poor performance of plain or under - reinforced footings during a seismic event. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles.

RATIONALE: No substantiating data has been provided to show that under - reinforced footings are effective in resisting seismic loads and may potentially lead to a higher risk of failure. Therefore, this proposed amendment requires minimum reinforcement in continuous footings to address the problem of poor performance of plain or under - reinforced footings during a seismic event. With the higher seismic demand placed on buildings and structures in this region, precautionary steps are proposed to reduce or eliminate potential problems that may result by following prescriptive design provisions for footing that does not take into consideration the surrounding environment. It was important that the benefit and expertise of a registered design professional be obtained to properly analyze the structure and take these issues into consideration. This amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Task Force that investigated the poor performance observed in the 1994 Northridge Earthquake. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to limit the use of the prescriptive design provisions and under - reinforced or plain concrete is to ensure that the proper analysis of the structure takes into account the surrounding condition and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments - Page 36 of 126 2013 Edition of the California Building Code - Final version: 9/512013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 18 -05. Section 1809.12 of the 2013 Edition of the California Building Code is amended to read as follows: 1809.12 Timber footings. Timber footings shall be permitted for buildings of Type V construction and as otherwise approved by the building official. Such footings shall be treated in accordance with AWPA U1 (Commodity Specification A, Use Category 4B). Treated timbers are not required where placed entirely below permanent water level, or where used as capping for wood piles that project above the water level over submerged or marsh lands. The compressive stresses perpendicular to grain in untreated timber footing supported upon treated piles shall not exceed 70 percent of the allowable stresses for the species and grade of timber as specified in the AF &PA NDS. Timber footings shall not be used in structures assigned to Seismic Design Category D, E or F. RATIONALE: No substantiating data has been provided to show that timber footings are effective in supporting buildings and structures during a seismic event, especially while being subjected to deterioration caused by the combined detrimental effects of moisture in the soil and wood - destroying organisms. Timber footings, when they are not properly treated and protected against deterioration, have performed very poorly. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic event and wet applications. The proposed amendment takes the precautionary steps to reduce or eliminate potential problems that may result by using timber footings that experience relatively rapid decay due to the face that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood - destroying organisms. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Climatic and Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. In addition, the region is within a climate system capable of producing major winds, fire and rain related disasters, including but not limited to those caused by the Santa Ana winds and El Nino (or La Nina) subtropical -like weather.

Section 1905.1.3 of the 2013 Edition of the California Building Code is amended to read as follows: 1905.1.3 ACI 318, Section 21.4. Modify ACI 318, Section 21.4, by renumbering Section 21.4.3 to become 21.4.4 and adding new Sections 21.4.3, 21.4.5, 21.4.6 and 21.4.7 to read as follows: 21.4.3 — Connections that are designed to yield shall be capable of maintaining 80 percent of their design strength at the deformation induced by the design displacement or shall use Type 2 mechanical splices. 21.4.4 — Elements of the connection that are not designed to yield shall develop at least 1.5 S 21.4.5— 21.13. 21.4.6 — Wall piers not designed as part of a moment frame in buildings assigned to Seismic Design Category C shall have transverse reinforcement designed to resist the shear forces determined from 21.3.3. Spacing of transverse reinforcement shall not exceed 8 inches (203 mm). Transverse reinforcement shall be extended beyond the pier clear height for at least 12 inches (305 mm). Exceptions: 1. Wall piers that satisfy 21.13. 2. Wall piers along a wall line within a story where other shear wall segments provide lateral support to the wall piers and such segments have a total stiffness of at least six times the sum of the stiffnesses of all the wall piers. 21.4.7 — Wall segments with a horizontal length -to- thickness ratio less than 2.5 shall be designed as columns. RATIONALE: The design provision for wall pier detailing was originally introduced by SEAOC in 1987 to legacy Uniform Building Code (UBC) and was included in the 1988 UBC through the 1997 UBC (2002 CBC). The wall pier detailing provision prescribed under Section 1905.1.4 was intended for high seismic zones equivalent to current Seismic Design Category D, E or F. Section 1905.1.3 was added as a complement of wall pier detailing in Seismic Design Category C (formerly seismic zones 2A and 2B under the legacy model code). ACI 318 Commentary R 21.1.1 emphasized "it is essential that structures assigned to higher Seismic Design Categories possess a higher degree of toughness ", and further encourages practitioners to use special structural wall system in regions of high seismic risk. ASCE 7 Table 12.2 -1 permits intermediate precast structural wall system in Seismic Design Category D, E or F. Current Section 1905.1.3 does not limit to just structures assigned to Seismic Design Category C. The required shear strength under 21.3.3, referenced in Section 21.4.6, is based on V„ under either nominal moment strength or two times the code prescribed earthquake force. The required shear strength in 21.6.5.1, referenced in Section 21.9.8.2 (IBC 1905.1.4), is based on the probable shear strength, V under the probable moment strength, M In addition, the spacing of required shear reinforcement is 8 inches on center under Section 21.4.6 instead of 6 inches on center with seismic hooks at both ends under Section 21.9.8.2. Requirement of wall pier under Section 21.9.8.2 would enhance better ductility. By virtue of ACI 318 Section 21.1.1.7(d), intermediate precast structural walls designed under Section 21.4, material requirements intended under provisions 21.1.4, 21.1.5, 21.1.6, and 21.1.7 would be 2013 LARUCP Recommended Technical Amendments - Page 39 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM excluded for structures assigned to Seismic Design Category D, E or F. Clarification of ACI 318 Chapter 21 is needed to ensure that structural walls designed under ASCE 7 Table 12.2 -1 using the intermediate wall panel category would conform to ductility requirements comparable to special structural wall; and conformance to the long standing practice of ACI 318 to impose special requirements for high seismic design regions. Whereas new ACI 318 section 21.4.4 extends requirement for wall piers be designed in accordance with 21.9 or 21.13. This amendment gives explicit requirement under which design and detailing need to conform to special structural wall system provision in ACI -318 Section 21.9, which covers both cast -in -place as well as precast. This amendment further gives building officials the tools to enforce minimum life safety building performance under earthquake forces in Seismic Design Category D, E or F. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. Current practice in commercial buildings constructed using precast wall panel systems have large window and door openings and /or narrow wall piers. Wall panels varying up to three stories high with openings resembles wall frame which is not currently recognized under any of the defined seismic -force resisting systems other than consideration of structural wall system. Conformance to special structural wall system design and detailing of wall piers ensures minimum life safety performance in resisting earthquake forces for structures in Seismic Design Category D, E or F. Proposed modification separates wall piers designed for structures assigned to Seismic Design Category C from those assigned to Seismic Design Category D, E or F. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. 11I N 1110 Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake.

Modify ACI 318, by adding Section 21.11.6.1 as follows: RATIONALE: This amendment is intended to carry over critical provisions for the design of concrete columns in moment frames from the legacy 1997 Uniform Building Code. Increased confinement is critical to the integrity of such columns and these modifications ensure that it is provided when certain thresholds are exceeded. In addition, this amendment carries over from the legacy 1997 Uniform Building Code a critical provision for the design of concrete shear walls. It essentially limits the use of very highly gravity - loaded walls in being included in the seismic load resisting system, since their failure could have catastrophic effect on the building. Furthermore, this amendment was incorporated in the code based on observations from the 1994 Northridge Earthquake. Rebar placed in very thin concrete topping slabs have been observed in some instances to have popped out of the slab due to insufficient concrete coverage. This modification ensures that critical boundary and collector rebars are placed in sufficiently thick topping slab to prevent buckling of such reinforcements.

The proposed modification to increase confinement in critical columns, limiting the use of highly gravity loaded walls, and increase concrete coverage in thin slabs will have to prevent failure of the structure and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 44 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 23 -01. Section 2304.9.1 of the 2013 Edition of the California Building Code is amended to read as follows: 2304.9.1 Fastener requirements. Connections for wood members shall be designed in accordance with the appropriate methodology in Section 23012. The number and size of fasteners connecting wood members shall not be less than that set forth in Table 2304.9.1. Staple fasteners in Table 2304.9.1 shall not be used to resist or transfer seismic forces in structures assigned to Seismic Design Category D, E or F. Exception: Staples may be used to resist or transfer seismic forces when the allowable shear values are substantiated by cyclic testing and approved by the building official. RATIONALE: Due to the high geologic activities in the Southern California area and the expected higher level of performance on buildings and structures, this proposed local amendment limit the use of staple fasteners in resisting or transferring seismic forces. In September 2007, limited cyclic testing data was provided to the ICC Los Angeles Chapter Structural Code Committee showing that stapled wood structural shear panels do not exhibit the same behavior as the nailed wood structural shear panels. The test results of the stapled wood structural shear panels appeared much lower in strength and drift than the nailed wood structural shear panel test results. Therefore, the use of staples as fasteners to resist or transfer seismic forces shall not be permitted without being substantiated by cyclic testing. This proposed amendment is a continuation of a similar amendment adopted during previous code adoption cycles.

Section 2304.11.7 of the 2013 Edition of the California Building Code is amended to read as follows: 2304.11.7 Wood used in retaining walls and cribs. Wood installed in retaining or crib walls shall be preservative treated in accordance with AWPA U1 (Commodity Specifications A or F) for soil and fresh water use. Wood shall not be used in retaining or crib walls for structures assigned to Seismic Design Category D, E or F. No substantiating data has been provided to show that wood used in retaining or crib walls are effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effect of constant moisture in the soil and wood - destroying organisms.

Section 2305.4 is added to Chapter 23 of the 2013 Edition of the California Building Code to read as follows: 2305.4 Quality of Nails. In Seismic Design Category D. E or F. mechanically driven nails used in wood structural panel shear walls shall meet the same dimensions as that required for hand - driven nails, including diameter, minimum length and minimum head diameter. Clipped head or box nails are not permitted in new construction. The allowable design value for clipped head nails in existing construction may be taken at no more than the nail- head -area ratio of that of the same size hand - driven nails. RATIONALE: The overdriving of nails into the structural wood panel still remains a concern when pneumatic nail guns are used for wood structural panel shear wall nailing. Box nails were observed to cause massive and multiple failures of the typical 3/8 -inch thick plywood during the 1994 Northridge Earthquake. The use of clipped head nails as allowed in Table Al of AFPA SDPWS footnote referencing to ASTM F1667, continues to be restricted from being used in wood structural panel shear walls where the minimum nail head size must be maintained in order to minimize nails from pulling through sheathing materials. Clipped or mechanically driven nails used in wood structural panel shear wall construction were found to perform much less in previous wood structural panel shear wall testing done at the University of California Irvine. The existing test results indicated that, under cyclic loading, the wood structural panel shear walls were less energy absorbent and less ductile. The panels reached ultimate load capacity and failed at substantially less lateral deflection than those using same size hand - driven nails. This amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake.

AC 155 uses monotonic loading to establish allowable values. Yet, cyclic and dynamic forces imparted on buildings and structures by seismic activity cause more damage than equivalent forces that are applied in a monotonic manner. However, the engineering, regulatory and manufacturing industries have not reached consensus on the appropriate cyclic or dynamic testing protocols. This condition is expected to continue for some time. In the interim, this proposed amendment continues to limit the allowable capacity to 75% of the evaluation report value to provide an additional factor of safety for statically tested anchorage devices. Steel plate washers will reduce the additional damage that can result when hold -down connectors are fastened to wood framing members. This amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles with additional editorial revisions for clarification. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake.

Section 2305.5 is added to Chapter 23 of the 2013 Edition of the California Building Code to read as follows: FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 23 -06. Section 2306.2 of the 2013 Edition of the California Building Code is amended to read as follows: 2306.2 Wood -frame diaphragms. Wood -frame diaphragms shall be designed and constructed in accordance with AF &PA SDPWS. Where panels are fastened to framing members with staples, requirements and limitations of AF &PA SDPWS shall be met and the allowable shear values set forth in Table 2306.2(1) or 2306.2(2) shall only be permitted for structures assigned to Seismic Design Category A. B, or C. Exception: Allowable shear values where panels are fastened to framing members with staples may be used if such values are substantiated by cyclic testing and approved by the building official. The allowable shear values in Tables 2306.2(1) and 2306.2(2) are permitted to be increased 40 percent for wind design. Exception: [DSA -SS, DSA -SS /CC and OSHPD 1, 2 &4] Wood structural panel diaphragms using staples as fasteners are not permitted by DSA and OSHPD. Wood structural panel diaphragms used to resist seismic forces in structures assigned to Seismic Design Category D. E or F shall be applied directly to the framing members. Exception: Wood structural panel diaphragms are permitted to be fastened over solid lumber planking or laminated decking, provided the panel joints and lumber planking or laminated decking joints do not coincide. RATIONALE: The Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the damages to buildings and structures during the 1994 Northridge Earthquake recommended reducing allowable shear values in wood structural panel shear walls or diaphragms that were not substantiated by cyclic testing. That recommendation was consistent with a report to the Governor from the Seismic Safety Commission of the State of California recommending that code requirements be "more thoroughly substantiated with testing." The allowable shear values for wood structural panel shear walls or diaphragms fastened with staples are based on monotonic testing and does not take into consideration that earthquake forces load shear wall or diaphragm in a repeating and fully reversible manner. In September 2007, limited cyclic testing was conducted by a private engineering firm to determine if wood structural panels fastened with staples would exhibit the same behavior as the wood structural panels fastened with common nails. The test result revealed that wood structural panel fastened with staples appeared to be much lower in strength and stiffness than wood structural panels fastened with common nails. It was recommended that the use of staples as fasteners for wood structural panel shear walls or diaphragms not be permitted to resist seismic forces in structures assigned to Seismic Design Category D, E and F unless it can be substantiated by cyclic testing. Furthermore, the cities and county within the Los Angeles region has taken extra measures to maintain the structural integrity of the framing of shear walls and diaphragms designed for high levels of seismic forces by requiring wood sheathing be applied directly over the framing members and prohibiting the use of panels placed over gypsum sheathing. This proposed amendment is intended to prevent the undesirable performance of nails when gypsum board softens due to cyclic earthquake displacements and the nail ultimately does not have any engagement in a solid material within the thickness of the gypsum board. 2013 LARUCP Recommended Technical Amendments Page 49 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM This proposed amendment continues the previous amendment adopted during the 2010 code adoption cycle.

FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM RATIONALE: The Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the damages to buildings and structures during the 1994 Northridge Earthquake recommended reducing allowable shear values in wood structural panel shear walls or diaphragms that were not substantiated by cyclic testing. That recommendation was consistent with a report to the Governor from the Seismic Safety Commission of the State of California recommending that code requirements be "more thoroughly substantiated with testing." The allowable shear values for wood structural panel shear walls or diaphragms fastened with stapled nails are based on monotonic testing and does not take into consideration that earthquake forces load shear wall or diaphragm in a repeating and fully reversible manner. In September 2007, limited cyclic testing was conducted by a private engineering firm to determine if wood structural panels fastened with stapled nails would exhibit the same behavior as the wood structural panels fastened with common nails. The test result revealed that wood structural panel fastened with stapled nails appeared to be much lower in strength and stiffness than wood structural panels fastened with common nails. It was recommended that the use of stapled nail as fasteners for wood structural panel shear walls or diaphragms not be permitted to resist seismic forces in structures assigned to Seismic Design Category D, E and F unless it can be substantiated by cyclic testing. Furthermore, the cities and county within the Los Angeles region has taken extra measures to maintain the structural integrity of the framing of shear walls and diaphragms designed for high levels of seismic forces by requiring wood sheathing be applied directly over the framing members and prohibiting the use of panels placed over gypsum sheathing. This proposed amendment is intended to prevent the undesirable performance of nails when gypsum board softens due to cyclic earthquake displacements and the nail ultimately does not have any engagement in a solid material within the thickness of the gypsum board. This proposed amendment continues the previous amendment adopted during the 2010 code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to place design and construction limits on stapled nail fasteners used in wood structural panel shear walls or diaphragms not substantiated with cyclic testing will help to maintain minimum quality of construction and performance standards of structures and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments Page 52 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 23 -07. Section 2308.3.4 of Chapter 23 of the 2013 Edition of the California Building Code is amended to read as follows: 2308.3.4 Braced wall line support. Braced wall lines shall be supported by continuous foundations. Exception: For structures with a maximum plan dimension not over 50 feet (15240 mm), continuous foundations are required at exterior walls only for structures assigned to Seismic Design Category A. B. or C RATIONALE: With the higher seismic demand placed on buildings and structures in this region, interior walls can easily be called upon to resist over half of the seismic loading imposed on simple buildings or structures. Without a continuous foundation to support the braced wall line, seismic loads would be transferred through other elements such as non - structural concrete slab floors, wood floors, etc. The proposed change is to limit the use of the exception to structures assigned to Seismic Design Category A, B or C where lower seismic demands are expected. Requiring interior braced walls be supported by continuous foundations is intended to reduce or eliminate the poor performance of buildings or structures. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. Conventional framing does not address the need for a continuous load path, critical shear transfer mechanisms, connection -ties, irregular and flexible portions of complex shaped structures. The proposed modification to require continuous footings under braced wall lines will improve performance of buildings or structure during a seismic event and therefore need to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the International Building Code. 2013 LARUCP Recommended Technical Amendments - - Page 53 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 23 -08.

Section R301.1.3.2 of the 2013 Edition of the California Residential Code is amended to read as follows: R301.1.3.2 Woodframe structure ^ -^=!er than two stories The building official shall require construction documents to be approved and stamped by a California licensed architect or engineer for all dwellings of woodframe construction more than two stories and basement in height located in Seismic Design Category A, B or C . Notwithstanding other sections of law; the law establishing these provisions is found in Business and Professions Code Section 5537 and 6737.1. The building official shall require construction documents to be approved and stamped by a California licensed architect or engineer for all dwellings of woodframe construction more than one story in height or with a basement located in Seismic Design Category Dn, D, D, or E. RATIONALE: After the 1994 Northridge Earthquake, the Wood Frame Construction Joint Task Force recommended that the quality of wood frame construction need to be greatly improved. One such recommendation identified by the Task Force is to improve the quality and organization of structural plans prepared by the engineer or architect so that plan examiners, building inspectors, contractors and special inspectors may logically follow and construct the presentation of the seismic force - resisting systems in the construction documents. For buildings or structures located in Seismic Design Category Do, D D or E that are subject to a greater level of seismic forces, the requirement to have a California licensed architect or engineer prepare the construction documents is intended to minimize or reduce structural deficiencies that may cause excessive damage or injuries in wood frame buildings. Structural deficiencies such as plan and vertical irregularities, improper shear transfer of the seismic force - resisting system, missed details or connections important to the structural system, and the improper application of the prescriptive requirements of the California Residential Code can be readily addressed by a registered design professional. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to require construction documents for wood frame construction greater than one story in height or with a basement to be approved and stamped by a California licensed architect or engineer is intended to assure that both the structural design and prescriptive requirement of the code are properly utilized and presented and therefore need to be incorporated into the code to assure that new buildings and structures, and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 62 of 126 2013 Edition of the California Building Code Final Version: 9/512013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP R3 -02. Section R301.1.4 is added to Chapter 3 of the 2013 Edition of the California Residential Code to read as follows: Code. RATIONALE: Due to the difficulty of fire suppression vehicles accessing winding and narrow hillside properties and the probabilities for future earthquakes in the Los Angeles region, this technical amendment is required to address the special needs for buildings constructed on hillside locations. A joint Structural Engineers Association of Southern California (SEAOSC) and both the Los Angeles County and Los Angeles City Task Force investigated the performance of hillside building failures after the Northridge earthquake. Numerous hillside failures resulted in loss of life and millions of dollars in damage. These criteria were developed to minimize the damage to these structures and have been in use by both the City and County of Los Angeles for several years with much success. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Topographical and Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. Additionally, the topography within the Los Angeles region includes significant hillsides with narrow and winding access that makes timely response by fire suppression vehicles challenging and difficult. The proposed modification establishes design parameters to better mitigate and limit property damage that are the results of increased seismic forces which are imparted upon hillside buildings and structures and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 63 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION. UNIFORM CODE PROGRAM 2013 LARUCP R03 -03. Table R301.2.2.1.1 and Section R301.2.2.1.2 of the 2013 Edition of the California Residential Code are amended to read as follows: TABLE R301.2.2.1.1 SEISMIC DESIGN CATEGORY DETERMINATION CALCULATED SIDS SEISMIC DESIGN CATEGORY SIDS <_ 0.17g A 0.17g < Sos < 0.33g B 0.33g < S <_ 0.509 C 0.509 < S <_ 0.67g D 0.67g < Sos <_ 0.83g D, 0.83g < S <_ 4 -- 5 9 - L Q_09 Dz 4- 23 1.009 < Sos E R301.2.2.1.2 Alternative determination of Seismic Design Category E. Buildings located in Seismic Design Category E in accordance with Figure R301.2(2) are permitted to be reclassified as being in Seismic Design Category D provided one of the following is done: 1. A more detailed evaluation of the seismic design category is made in accordance with the provisions and maps of the California Building Code. Buildings located in Seismic Design Category E per Table R301.2.2.1.1, but located in Seismic Design Category D per the California Building Code, may be designed using the Seismic Design Category D requirements of this code. 2. Buildings located in Seismic Design Category E that conform to the following additional restrictions are permitted to be constructed in accordance with the provisions for Seismic Design Category D of this code: 2.1.All exterior shear wall lines or braced wall panels are in one plane vertically from the foundation to the uppermost story. 2.2. Floors shall not cantilever past the exterior walls. 2.3. The building is within all of the requirements of Section R301.2.2.2.5 for being considered as regular. 2.4. For buildings over one story in height, the calculated S shall not exceed 1.258. RATIONALE: The purpose of this amendment is to revise the IRC short period design acceleration from 1.25g to 1.0g for SDC D as ASCE7 -10 limits the short period acceleration to 1.5g working out to S of 1.0g; then to limit the Sos to 1.25g for IRC SDC E structure reclassification. Currently, under ASCE 7 -10, SDC D has a wide range from 0.50g < S and that for regular structures S may be taken as 1.5g for calculating SDS. This translates to setting a limit of S =1.00 g for regular structure based on ASCE 7. IRC places Sos 1.25g into SDC E. However, under IRC, structures meeting the regular structure criteria may be re- classified as D The limit of 1.25g for the SDC E re- classification in IRC imposes a lower standard for irregular residential structures. This gives a disparity for the equal risk concept in the development of the ASCE 7 -10 seismic hazard maps. ASCE 7 -10 seismic hazard maps have also adjusted S and S, downward for parts of the middle and eastern United States between 2009 IRC and 2012 IRC. 2013 LARUCP Recommended Technical Amendments Page 64 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM The SDC D limit in Table R301.2.2.1.1 is changed to 0.83g < SDS < 1.00g. This corresponds to the delineation to a limit of S of 1.5g for regular structure under ASCE 7 -10. The added exception item 2.4 permits reclassification of SDC E to D up to 1.25g. The associate risk for one- and two- family residential regular structure justifies the increase limit of S It is expected that structures beyond the limits set forth will be engineered under IBC provisions. Reference ASCE 7 -10 Section 12.8.1.3 Maximum S Value in Determination of C For regular structures five stories or less above the base as defined in Section 11.2 and with a period, T, of 0.5s or less, C is permitted to be calculated using a value of 1.5 for S ASCE 7 -10 Section C12.8.1.3 Maximum S Value in Determination of C The maximum value of S was created as hazard maps were revised in 1997. The cap on S reflects engineering judgment about performance of code - complying buildings in past earthquakes so the structural height, period, and regularity conditions required for use of the limit are very important qualifiers. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake, the 1987 Whittier Narrows Earthquake, the 1971 San Fernando Earthquake and the 1933 Long Beach Earthquake. This amendment will improve the performance of buildings that otherwise may be designed and constructed in accordance with the CRC during a significant earthquake. This amendment is in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 65 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP R3-04.

Code. Such limitations are intended to reduce the potential structural damage expected in the event of an earthquake. The cities and county of the Los Angeles region has taken extra measures to maintain the structural integrity of the framing of the shear walls and all associated elements when designed for high levels of seismic loads. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed amendment limits the type of irregular conditions within buildings that may lead to higher structural damage during a seismic event and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code and consistent with the requirements in the ASCE 7 -10. 2013 LARUCP Recommended Technical Amendments - Page 67 of 126 2013 Edition of the California Building Code Final Version: 9/512013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP R3 -05. Section R301.2.2.3.8 is added to Chapter 3 of the 2013 Edition of the California Residential Code to read as follows: R301.2.2.3.8 Anchorage of Mechanical. Electrical, or Plumbing Components and Equipment. Mechanical, electrical, or plumbing components and equipment shall be anchored to the structure. Anchorage of the components and egumment shall be designed to resist loads in accordance with the International Building Code and ASCE 7, except where the component is positively attached to .the structure and flexible connections are provided between the component and associated ductwork piping and conduit: and either 1. The component weighs 400 lb (1,780 N) or less and has a center of mass located 4 ft (1.22 m) or less above the supporting structure: or 2. The component weighs 20 lb (89N) or lessor, in the case of a distributed system, 5 lb/ft (73 N /m) or less. RATIONALE: There is no limitation for weight of mechanical and plumbing fixtures and equipment in the International Residential Code. Requirements from ASCE 7 and the International Building Code would permit equipment weighing up to 400 lbs. when mounted at 4 feet or less above the floor or attic level without engineering design. Where equipment exceeds this requirement, it is the intent of this proposed amendment that a registered design professional be required to analyze if the floor support is adequate and structurally sound. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to limit the equipment weight is intended to reduce injuries, save lives, and minimize structural damages and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments - Page 68 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 114 -01. Section R401.1 of the 2013 Edition of the California Residential Code is amended to read as follows: R401.1 Application. The provisions of this chapter shall control the design and construction of the foundation and foundation spaces for all buildings. In addition to the provisions of this chapter, the design and construction of foundations in areas prone to flooding as established by Table R301.2(1) shall meet the provisions of Section R322. Wood foundations shall be designed and installed in accordance with AF &PA PWF. Exception: The provisions of this chapter shall be permitted to be used for wood foundations only in the following situations: 1. In buildings that have no more than two floors and a roof. 2. When interior basement and foundation walls are constructed at intervals not exceeding 50 feet (15 240 mm). Wood foundations in Seismic Design Category Do, D or D shall b e deSigRed on ^^^ ^r-'^^^° with EIGG epted °^^i^^^^^^ ^ ^^ ti^° not be permitted. Exception: In non - occupied, single -story , detached storage sheds and similar uses other than carport or garage, provided the gross floor area does not exceed 200 square feet, the plate height does not exceed 12 feet in height above the grade plane at any point, and the maximum roof proiection does not exceed 24 inches. RATIONALE: No substantiating data has been provided to show that wood foundation is effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effect of constant moisture in the soil and wood - destroying organisms. Wood foundation, when they are not properly treated and protected against deterioration, have performed very poorly and have led to slope failures. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic event and wet applications. The proposed amendment takes the precautionary steps to reduce or eliminate potential problems that may result in using wood foundation that experience relatively rapid decay due to the fact that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood - destroying organisms. However, an exception is made for non - occupied, single -story storage structures that pose significantly less risk to human safety and may utilize the wood foundation guidelines specified in this Chapter. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles for the California Residential Code. FINDINGS: Local Climatic and Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. In addition, the region is within a climate system capable of producing major winds, fire and rain related disasters, including but not limited to those caused by the Santa Ana winds and El Nino (or La Nina) subtropical -like weather. This region is especially susceptible to more active termite and wood attacking insects and microorganisms.

Sections R403.1.2, 8403.1.3 and R403.1.5 of the 2013 Edition of the California Residential Code are amended to read as follows: R403.1.2 Continuous footing in Seismic Design Categories D D, and D The braced wall panels at exterior walls of buildings located in Seismic Design Categories D D, and D shall be supported by continuous footings. All required interior braced wall panels in buildings with plan diFReRS 9RS gFeater than 50 F^°" n)- shall alssa -be supported by continuous footings. R403.1.3 Seismic reinforcing. Concrete footings located in Seismic Design Categories D D, and D as established in Table R301.2(1), shall have minimum reinforcement. Bottom reinforcement shall be located a minimum of 3 inches (76 mm) clear from the bottom of the footing. In Seismic Design Categories D D, and D where construction joint is created between a concrete footing and a stem wall, a minimum of one No. 4 bar shall be installed at not more than 4 feet (1219 mm) on center. The vertical bar shall extend to 3 inches (76 mm) clear of the bottom of the footing, have a standard hook and extend a minimum of 14 inches (357 mm) into the stem wall. In Seismic Design Categories D D, and D where a grouted masonry stem wall is supported on a concrete footing and stem wall, a minimum of one No. 4 bar shall be installed at not more than 4 feet (1219 mm) on center. The vertical bar shall extend to 3 inches (76 mm) clear of the bottom of the footing and have a standard hook. In Seismic Design Categories Do, D, and D masonry stem walls without solid grout and vertical reinforcing are not permitted. Exception: In detached one- and two- family dwellings located in Seismic Design Category A, B or C which are three stories or less in height and constructed with stud bearing walls, isolated plain concrete footings, supporting columns or pedestals are permitted. R403.1.5 Slope. The top surface of footings shall be level. The bottom surface of footings shall be permitted to have a slope not exceeding one unit vertical in 10 units horizontal (10- percent slope). Footings shall be stepped where it is necessary to change the elevation of the top surface of the footing or where the surface of the ground slopes more than one unit vertical in 10 units horizontal (10- percent slope). For structures located in Seismic Design Categories D n. D, or D stepped footings shall be reinforced with four No. 4 rebar.

Requiring minimum reinforcement for stepped footings is intended to address the problem of poor performance of plain or under - reinforced footings during a seismic event. Furthermore, interior walls can easily be called upon to resist over half of the seismic loading imposed on simple buildings or structures. Without a continuous foundation to support the braced wall line, seismic loads would be transferred through other elements such as non- structural concrete slab floors, wood floors, etc. The proposed change is to limit the use of the exception to structures assigned to Seismic Design Category A, B or C where lower seismic demands are expected. Requiring interior braced walls be supported by continuous foundations is intended to reduce or eliminate the poor performance of buildings or structures. This proposed amendment is consistent with an amendment adopted during previous code adoption cycles for the California Residential Code. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to require continuous footings under braced wall lines, require reinforcement in one- and two - family dwelling, and minimum reinforcement in stepped footings will improve performance of buildings or structure during a seismic event and minimize potential problems or deficiencies and therefore need to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 72 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 114 -03.

In addition, shear walls sheathed with other materials are prohibited in Seismic Design Category D D, and D to be consistent with the design limitation for similar shear walls found in the California Building Code. The poor performance of such shear walls in the 1994 Northridge Earthquake was investigated by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Task Force and formed the basis for this proposed amendment. Considering that shear walls sheathed with lath, plaster or gypsum board are less ductile than steel moment frames or wood structural panel shear walls, the cities and county of the Los Angeles region has taken the necessary measures to limit the potential structural damage that may be caused by the use of such walls at the lower level of multi -level building that are subject to higher levels of seismic loads. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to increase the length and limit the location where shear walls sheathed with lath, plaster or gypsum board are used will help to ensure that multi -level building will reach it's performance objective in resisting higher levels of seismic loads and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 82 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP R6-04.

Section R602.10.9.1 of the 2013 Edition of the California Residential Code is deleted in its entirety: RATIONALE: With the higher seismic demand placed on buildings and structures in this region, interior walls can easily be called upon to resist over half of the seismic loading imposed on simple buildings or structures. Without a continuous foundation to support the braced wall line, seismic loads would be transferred through other elements such as non - structural concrete slab floors, wood floors, etc. Requiring interior braced walls be supported by continuous foundations is intended to reduce or eliminate the poor performance of buildings or structures. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to require all exterior walls and interior braced wall panels in buildings be supported on continuous footings for a complete load path will improve performance of buildings or structure during a seismic event and therefore, need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 95 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 116 -11. Section R606.2.4 of the 2013 Edition of the California Residential Code is amended to read as follows: R606.2.4 Parapet walls. Unreinforced solid masonry parapet walls shall not be less than 8 inches (203 mm) thick and their height shall not exceed four times their thickness. Unreinforced hollow unit masonry parapet walls shall be not less than 8 inches (203 mm) thick, and their height shall not exceed three times their thickness. Masonry parapet walls in areas subject to wind loads of 30 pounds per square foot (1.44 kPa) or located in Seismic Design Category Do, Dt or D or on townhouses in Seismic Design Category C shall be reinforced in accordance with Section R606.12. RATIONALE: The addition of the word "or" will prevent the use of unreinforced parapets in Seismic Design Category D Dt or D or on townhouses in Seismic Design Category C. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles, region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to not allow the use of unreinforced masonry is intended to prevent non - ductile failures and sudden structural collapses and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments - Page 96 of. -126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP 116 -12. Section R606.12.2.2.3 of the 2013 Edition of the California Residential Code is amended to read as follows: R606.12.2.2.3 Reinforcement requirements for masonry elements. Masonry elements listed in Section R606.12.2.2.2 shall be reinforced in either the horizontal or vertical direction as shown in Figure ° 2-)R606.11(31 and in accordance with the following: Horizontal reinforcement. Horizontal joint reinforcement shall consist of „ uE; not a e°a;nn n inches (102 Fnm '.. .; , .. at least one No. 4 bar spaced not more than 48 inches (1219 mm).

Vertical reinforcement. Vertical reinforcement shall consist of at least one No. 4 bar spaced not more than 48 inches (1219 mm). Vertical reinforcement shall be within 46-8 inches (406mm) of the ends of masonry walls. RATIONALE: Reinforcement using longitudinal wires for buildings and structures located in high seismic areas are deficient and not as ductile as deformed rebar. Having vertical reinforcement closer to the ends of masonry walls help to improve the seismic performance of masonry buildings and structures. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to increase reinforcements will ensure that the ductility requirements for buildings in high seismic region meet the intent of the code and limit potential property damages and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 97 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP R6 -13. Exception of Section R602.3.2 of the 2013 Edition of the California Residential Code is amended to read as follows: Exception: A other than Seismic Design Category D .D or Q a single top plate may be installed in stud walls, provided the plate is adequately tied at joints, corners and interesting walls by a minimum 3- inch -by -6 -inch by a 0.036- inch -thick (76 mm by 152 mm by 0.914 mm) galvanized steel plate that is nailed to each wall or segment of wall by six 8d nails on each side, provided the rafters or joists are centered over the studs with a tolerance of no more than 1 inch (25 mm). The top plate may be omitted over lintels that are adequately tied to adjacent wall sections with steel plates or equivalent as previously described. RATIONALE: The cities and county of the Los Angeles region have taken extra measures to maintain the structural integrity of the framing of the shear wall system for buildings and structures subject to high seismic loads by eliminating single top plate construction. The performance of modern day braced wall panel construction is directly related to an adequate load path extending from the roof diaphragm to the foundation system. A single top plate is likely to be over nailed due to the nailing requirements at a rafter, stud, top plate splice, and braced wall panel edge in a single location. In addition, notching on a single top plate for plumbing, ventilation and electrical wiring may reduce the load transfer capacity of the plate without proper detailing. Majority of buildings and structures designed and built per the California Residential Code with a single top plate may not need structural observation and special inspections. The potential construction mistakes mentioned above could not be caught and corrected by knowledgeable engineers and inspectors, and could jeopardize structural performance of buildings and structures located in high seismic areas. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to eliminate the usage of a single top plate will help to maintain minimum quality of construction and performance standards of structures and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 98 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP R8 -01. Section R803.2.4 is added to Chapter 8 of the 2013 Edition of the California Residential Code to read as follows: R803.2.4 Openings in horizontal diaphragms. Openings in horizontal diaphragms shall conform with Section R503.2.4. RATIONALE: Section R802 of the Code does not provide any prescriptive criteria to limit the maximum roof opening size nor does Section R803 provide any details to address the issue of shear transfer near larger roof openings. With the higher seismic demand placed on buildings and structures in this region, it is important to ensure that a complete load path is provided to reduce or eliminate potential damages caused by seismic forces. Requiring blocking with metal ties around larger roof openings and limiting opening size is consistent with the requirements of Section R301.2.2.2.5. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to require specific detailing at large roof openings is intended to address the poor performance of roof diaphragms with openings and limit or reduce property damages during a seismic event and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. .2013 LARUCP Recommended Technical Amendments Page 99 of 126 2013 Edition of the California Building Code Final Version: 915/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP R10 -01. Section R1001.3.1 of the 2013 Edition of the California Residential Code is amended to read as follows: R1001.3.1 Vertical reinforcing. For chimneys up to 40 inches (1016 mm) wide, four No. 4 continuous vertical bars adequately anchored into the concrete foundation shall be placed between wythes of solid masonry or within the cells of hollow unit masonry and grouted in accordance with Section R609. Grout shall be prevented from bonding with the flue liner so that the flue liner is free to move with thermal expansion. For chimneys more than 40 inches (1016 mm) wide, two additional No. 4 vertical bars adequately anchored into the concrete foundation shall be provided for each additional flue incorporated into the chimney or for each additional 40 inches (1016 mm) in width or fraction thereof. RATIONALE: The performance of fireplace /chimney without anchorage to the foundation has been observed to be inadequate during major earthquakes. The lack of anchorage to the foundation can result in the overturning or displacement of the fireplace /chimney. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to anchor masonry chimneys into concrete foundation will reduce injuries, save lives, and minimize structural damages and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the International Residential Code. 2013 LARUCP Recommended Technical Amendments Page 100 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM PART III RECOMMENDED LARUCP AMENDMENTS TO THE 2013 EDITION OF THE CALIFORNIA GREEN BUILDING STANDARDS CODE (MANDATORY REQUIREMENTS) 2013 LARUCP Recommended Technical Amendments Page 101 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM SUMMARY OF RECOMMENDED LARUCP AMENDMENTS TO THE 2013 CGBSC (N) 2013 LARUCP NO.

Section 202 of the 2013 Edition of the California Green Building Standards Code is amended to read as follows: SUSTAINABILITY. Consideration of present development and construction impacts on the community, the economy, and the environment without compromising the needs of the future. RATIONALE: The 2013 California Green Building Standards Code contains the word "sustainable" but does not define it. Although it is a term used in association with green building, the word "sustainability ": is often confused to mean the same as green building. The proposed amendment allows clarity and distinguishing understanding while.providing for a general definition.

Section 301.1.1 of the 2013 Edition of the California Green Building Standards Code is amended to read as follows: Section 301.1.1 Additions and alterations. [HCD] The mandatory provisions of Chapter 4 shall be applied to additions or alterations of existing residential buildings ;:here the eaa?t'.enr er alterctons eF size. The requirement shall apply Gnly to andier w ith, 8... n ..:F.. n 9f the ..dditi o' alteration. Code sections relevant to additions and alterations shall only apply to the portions of the building being added or altered within the scope of the permitted work. RATIONALE: The purpose of the proposed amendment is to simplify the language and increase the scope of application, thus requiring CALGreen to be applied to all residential projects. California State Housing and Community Development proposed the above 2013 CALGreen code section. The proposed section can only be applied to an existing house only if the volume or size of the condition space is increased. This proposed section, as written, does not encompass interior remodels. The proposed amendment modifies the State language to require additions, alterations, and interior remodels to comply with sections of CALGreen that are relevant to the scope of work. CALGreen and other green building codes have been developed and implemented for some very basic reasons: water, energy, and air quality. The 2010 U.S. Census shows that California has a population of 37.25 million, 13.7 million homes and with ownership at 56.7 %. UCLA Anderson Construction Forecast, a highly recognized authority in predicting the future of construction in the State, has provided the following statistics: 2011 612,000 new homes constructed 2012 763,000 new homes constructed 2013 Just fewer than one million homes will be constructed 2014 1.3 million new homes constructed Total 3.675 million new homes in four years. These simple numbers illustrate that the new homes built in the last four years only equal approximately 9.9% of the total housing stock in the State. These houses comply with the new 2010 Green Standards, but the larger challenge is with the existing housing inventory. The bulk of California's energy is generated by aging power plants. Increasingly, the development and application of alternate energy methods such as photovoltaics has gained market adoption. Coupling these new energy generation processes with new energy saving measures in the 2013 California Energy Code will allow us to potentially offset the need to construct new power plants, which would equate to a savings of billions of tax -payer dollars. Water conservation is another issue being addressed by the new green codes. CALGreen addresses water conservation with requirements for landscape irrigation and plumbing fixtures. In the 2013 code edition kitchen facets will now have to comply with a slightly reduced flow. Starting January 1, 2014 a new State law goes into effect that prohibits the selling of any plumbing fixture that does not conform to the new established flow rates. CALGreen also address's indoor air quality. Within the code there are multiple limits for VOC (volatile organic compounds) in paints, sealants and construction adhesives and formaldehyde contents in composite wood products. These new standards which restrict VOC and formaldehyde contents have shown to improve indoor air quality and minimize or eliminate occupant health issues related to sick building syndrome. 2013 LARUCP Recommended Technical Amendments Page 107 of 126 2013 Edition of the California Building Code Final Version: 9/512013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM FINDINGS: Local Environmental Conditions — The majority of the building stock in the greater Los Angeles region are existing residences. The U.S. Census and the UCLA Anderson Construction Forecast reveal that there are 13.7 million homes in California in 2010, with 2.7 million new homes built in the past three years, illustrates that there are more than five times the number of existing homes as there are new homes built under the CALGreen code. To reduce the impact that the existing housing stock is having on energy, water, and air quality, this amendment proposes to address compliance with the CALGreen code at the time when a permit is issued. There are some estimates that existing buildings account for up to 40% of greenhouse gas emissions. This amendment offset this impact on the communities by implementing the green building measures whenever possible. Any projects that require a permit to be issued will be required to comply with only those sections that are relevant to the scope of work and thereby begin to contribute to improving the environment. This amendment established green building standards and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Green Building Standards Code. 2013 LARUCP Recommended Technical Amendments Page 108 of 126 2013 Edition of the California Building Code Final Version: 9/5/2013 2013 Edition of the California Residential Code 2013 Edition of the California Green Building Standards Code FY 2013 LOS ANGELES REGION UNIFORM CODE PROGRAM 2013 LARUCP G5 -01. Section 5.408.3 of the 2013 Edition of the California Green Building Standards Code is amended to read as follows: 5.408.3 Excavated soil and land clearing debris [BSC] 100 percent of trees, stumps, rocks and associated vegetation and soils resulting primarily from land clearing shall be reused or recycled. For a phased project, such material may be stockpiled on site until the storage site is developed. Exception: Reuse, either on -or off -site, of vegetation or soil contaminated by disease or pest infestation. Notes: 1. If contamination by disease or pest infestation is suspected, contact the County Agricultural Commissioner and follow its direction for recycling or disposal of the material. ( www.cdfa.ca.gov/ exec / county /county_contacts.html) 2. For a map of known pest and /or disease quarantine zones, consult with the California Department of Food and Agriculture. (www.cdfa.ca.gov) 3. Contaminated soil shall not be reused and shall be disposed of or remediated in accordance with relevant regulations. ZI—A1101k On occasions, projects are proposed on sites where the soil is contaminated and falls outside the scope of a designated authority. The addition of Note #3 provides a mechanism for a local jurisdiction to administer to the removal or remediation of contaminated soils within guidelines established by the city or method developed by the applicant and approved by the local jurisdiction.
