Agenda packet, special meeting — Glendale City Council, May 14, 2024 (part 2 of 2)

This amendment modifies an exception to require special inspections to detached one -or-two family dwellings located in Seismic Design Category D, E or F.

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. 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 bui ldings and structures in this region, the language in Sections 1705.12 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.

58. 1805.4.3 Drainage discharge.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Build ing and Safety Code. This amendment requires site drainage device s, for all concentrated water, to be installed to the satisfaction of the building official and city engineer. This amendment will reduce damage and help prevent injury by requiring that drainage systems be installed to minimum standards established by the building official and the city engineer, thereby providing better control of the effect of concentrated drainage on property.

1807.1.6 Prescriptive design of concrete and masonry foundation walls.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code. This amendment requires foundation walls be designed by licensed professionals and deletes references to prescriptive tables which allow plain concrete or excessively slender walls. 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 amendment prohibits the use of staples as fasteners to resist or transfer seismic forces and shall not be permitted without being substantiated by cyclic testing. 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 resistin g 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.

2304.10.3.1 Quality of nails.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code.

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 A1 of AFPA SDPWS footnote referencing to ASTM F1667, continues to be restricted from being used in wood structural pan el 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 pane ls 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 obser ved in 1994 Northridge

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. Wood used in retaining or crib walls, when they are not properly treated and protected against deterioration, have performed very poorly.

This amendment is the same as in the 1999, 2002, 2008, 20011, 2014, 2017 and 2020 Glendale Building and Safety Code. This amendment requires seismic hold-down connectors to be designed based on cyclic load values, or 75 percent of non-cyclic load values. Additionally, steel plate washers are required when connection involves wood framing members.

ICC-ES AC 155 Acceptance Criteria for Hold-downs (Tie-Downs) Attached to Wood Members is widely used to establish allowable values for hold-down connectors in evaluation reports. AC 155 uses monotonic loading to establish allowable values. Yet, cyclic and dynamic forces imparted on build ings and structures by seismic activity cause more damage than equivalent forc es 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 anch orage devices. Steel plate washers will reduce the additional damage that can result when hold -down connectors 346

2306.2 Wood-frame diaphragms.

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code.

This amendment disallows the use of higher allowable (horizontal) diaphragm shear stress based on numerical calculation and requires the use of unit shear strength values as specified by the Code. 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 are not substantiated by cyclic testing. That recommendation was consistent with a report to the Governor from the Seismic Safety Commission of the State of Californ ia 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 na ils. 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 h as 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 amendment disallows the use of higher allowable diaphragm shear stress based on numerical calculation and requires the use of unit shear strength values as specifi ed by the Code. This amendment also limits the minimum thickness of wood structural panel sheathing and establishes minimum nail spacing requirements. This amendment is necessary because unit shear strength values specified in the Code are based on actual cyclic tests, thereby providing a more reliable design strength. Furthermore, review of actual damage caused by recent earthquakes has revealed that diaphragms sheathed with thinner wood structural panels performed poorly and may have contributed to increased structural damage.

This amendment requires interior braced walls (shear walls) to be supported by continuous foundations, thereby ensuring a substantial means of transferring loads to the supporting material.

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 stru ctures.

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 amendment eliminates the use of single top plate construction to maintain the structural integrity of the framing of shear wall systems for building and structures subject to high seismic loads.

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 amendment is the same as in the 2014, 2017 and 2020 Glendale Building and Safety Code.

This proposed amendment is consistent with an amendment adopted during previous code adoption cycles for the California Building Code. Plywood shear walls with high aspect ratio experienced m any failures during the Northridge Earthquake. This amendment specifies a minimum braced wall length to meet an aspect ratio consistent with other sections of the Residential Code 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 and reduce and limit potential damages to property. This amendment reflects the recommendations by the Structural Engin eers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake.

This amendment is the same as in the 2014, 2017 and 2020 Glendale Building and Safety Code.

This amendment is also consistent with an amendment adopted during previous code adoption cycles for the California Building Code.

Due to the high geologic activities in the Southern California area and the expected higher level of performance on buildings and structures, this amendment increases the length and limits the location where shear walls sheathed with lath, plaster or gypsum board are used in multi -level buildings. In addition, shear walls sheathed with other materials are prohibited in Seismic Design Category D 0, D1 and
D2 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.

44 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.

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 0, D1 and D2 unless it
can be substantiated by cyclic testing.

307.4.3 Portable outdoor fireplaces.

This amendment is the same as in the 2020 Glendale Building and Safety Code. This amendment adds restrictions related to the use of portable outdoor fireplaces when used in conjunction with one- and two- family dwellings located within a wildland-urban interface fire area. Glendale is located in a region that has a seasonally dry climate, which often experiences strong Santa Ana wind conditions. The additional restrictions require a minimum separation of 15 feet between the portable outdoor fire place and any structure, combustible material or vegetation, to address the increased fire hazards that are associated with seasonal high-wind conditions which increase the risk of open -flame devices in the wildland-urban interface fire areas. The wildland-urban interface fire areas are located in areas of the city where steep, hillside topography increase the difficulty in addressing wind -driven fire events. (Justification: Climatic)

Section VI-1

6. 307.4.4 “Red-flag” and other high fire risk conditions.

This amendment is essentially the same as in the 2020 Glendale Building and Safety Code with some minor editorial updates. This amendment adds restrictions on open burning activities, includ ing recreational fires and fires within portable outdoor fireplaces, on “red -flag” days or other days which pose a high fire risk. Glendale is located in a region that has a seasonally dry climate, which often experiences strong Santa Ana wind conditions.

Section VI – 26
.
901.11 Critical equipment
This amendment is the same as the 2020 Glendale Building and Safety Code. This amendment defines “critical equipment”, and then establishes criteria for its loca tion, ventilation, signage, and graphics.

Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of structural damage within buildings. Placement of critical equipment above the first floor of a building increases the likelihood that such equipment will be inaccessible for proper use after an earthquake.

Furthermore, earthquake-induced fires are more likely to occur in regions of high seismicity, and proper ventilation of critical equipment is necessary to maintain a tenable environment where such critical equipment must be accessed during an earthquake -induced fire. (Justification: Geologic)

Section VI – 27
.
903.2.21 Where required
This amendment is the same as the 2020 Glendale Building and Safety Code reflecting Glendale’s fire sprinkler ordinance for both new and existing buildings originally adopted in 1989. Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of earthquake -induced fires. Climatically, seasonal Santa Ana wind conditions have the potential to exacerbate fire conditions, thereby placing a higher degree of reliance upon automatic fire sprinkler systems to assist in the early abatement of structure fires. Topographically, portions of Glendale are located within hillside areas that are accessible by steep, narrow and winding streets, which can delay the arrival of fire suppression resources; automatic fire sprinkler systems can provide early suppression until fire suppression resources can arrive on scene. All of these conditions contribute to the need for increased fire sprinkler standards.

This amendment also includes administrative procedures for notification and enforcement. (Justification: Administrative, Geologic, Climatic , Topographic)

Section VI – 27
.
906.8 Cabinets

The code has two separate provisions for fire extinguishers weighing less than or more than 40 pounds. This amendment establishes administrative standards for the placement of fire extinguisher cabinets, to ensure that fire extinguishers are located in cabinets to ensure location control of fire extinguishers. The height provision contained in the amendment is intended to coordinate with disabled access provisions to ensure fire extinguishers are accessible to individuals with physical disabilities. This amendment is administrative and does not affect any building standards. (Justification: Administrative)

Section VI – 29
.
907.6.6 Monitoring
This amendment is essentially the same as the 2020 Glendale Building and Safety Code with a revision to further ensure the reliability of fire alarm monitoring systems by requiring monitoring systems to comply with NFPA 72’s provisions for central station monitoring service, a more reliable and accountable monitoring method. This amendment is administrative and does not affect any building standards.

Appendix B, Table B105.2, Required fire flow for buildings other than one - and two-family dwellings, group R-3 and R-4 buildings and townhouses
This amendment is the same as the 2020 Glendale Building and Safet y. This amendment revises the model code’s reduction of fire flow from 75% to no more than 50% for buildings other than one - and two- family dwellings. Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of earthquake-induced damage to municipal water supply lines. Additionally, large magnitude seismic events often result in loss of power at water distribution pump stations, thereby interfering with water pressure throughout the city. The proposed amendment requires a greater fire flow requirement for buildings other than one- and two-family dwellings, thereby increasing the likelihood of adequate water supply to fight fires after a major seismic event that compromises the municipal water supply.
(Justification: Geologic)

Section VI – 38
.

Appendix C, Table C102.1, Required number and spacing of fire hydrants This amendment is the same as the 2020 Glendale Building and Safety Code which establishes fire hydrant spacing requirements, with some minor editorial clarifications.

TITLE 24 OF THE CALIFORNIA CODE OF REGULATIONS

A. This amendment is necessary for administrative clarification, and does not modify a California Building Standard pursuant to California Health and Safety Code Sections 17958, 17958.5 and 17958.7. This amendment establishes administrative standards for the effective enforcement of building standards throughout the City of Glendale.

B. This amendment is justified on the basis of a local geologic condition. The City is subject to earthquake hazards caused by its location on the Sierra Madre fault near the base of the San Gabriel Mountains. Said fault is the eastward extension of the same fault upon which the 1971 San Fernando earthquake originated. Other faults which potentially could cause seismic activity in the City include the Verdugo fault located near the southwest edge of the Verdugo Mountains and its branches to the east, the Sycamore Canyon fault, the Scholl Canyon fault and the Eagle Rock and San Rafael faults. The York Boulevard fault is also important in that it is a western extension of the Raymond Hill fault for which there is considerable evidence for recent geologic activity. Said faults are generally considered major Southern California earthquake faults which may experience rupture at any time. Thus, because the City is within a seismic area which includes earthquake faults within and through the jurisdictional limits of the City, the modifications and changes cited herein are designed to better limit property damage as a result of seismic activity and to establish criteria for repair of damaged property following a local emergency.

C. This amendment is justified on the basis of a local climatic condition. The seasonal climatic conditions during the late summer and fall create severe fire hazards to the public health and welfare in the city. The hot, dry weather in combination with Santa Ana winds frequently results in wildland fires in the thousands of acres of brush- covered slopes in the Verdugo and San Rafael Hills, Chevy Chase Hills, and Repetto Hills area of the City. These areas extend from the City's boundary on the east to the Angeles National Forest in the north and the Verdugo Mountains at the Burbank boundary to the west. The aforementioned conditions combined with the geological characteristics of the hills within the City create hazardous conditions for which departure from the California Building Standards Code is required.

D. Glendale topography includes significant hillsides with narrow and winding access, which makes timely response by fire suppression vehicles difficult.

Additionally, long periods of dry, hot weather, combined with unpredictable seasonal winds (Santa Ana wind conditions) result in increased exposure to fire risk. The modifications and additions to the California Building Standards Code are reasonably necessary to combat the hazards brought about by local climatic conditions. Glendale has a desert weather pattern with monsoon type rain followed by long periods of hot, dry weather. The heavy rains tend to oversaturate the soil for a short time period during the year, having a detrimental effect on in-ground structures affected by varying moisture conditions. The City is situated on the alluvial flood plains of the Arroyo Verdugo Wash, Sycamore, Verdugo and Scholl Canyons and the Verdugo and San Gabriel Mountain drainages which have an 418
EXHIBIT 1
424 of 518

D:\Exhibit 1\Attachment 15_GBSC_2023_Key to Justification for Amendments.doc 2 extensive history of slope failures causing serious floods and mud slides especially when a heavy rainy season occurs after a severe brush fire. New constructions or additions in said areas must be regulated to assure that hillside slides will not be exacerbated, and if possible, will be improved.

E. This amendment is necessary for administrative clarification, which does not modify a California Building Standard pursuant to California Health and Safety Code Sections 17958, 17958.5 and 17958.7. This amendment establishes administrative standards for the effective enforcement of grading standards throughout the City of Glendale.

F. This amendment is justified on the basis of a local geologic condition. The City of Glendale is subject to earthquake hazards caused by its location on the Sierra Madre fault near the base of the San Gabriel Mountains. Said fault is the eastward extension of the same fault upon which the 1971 San Fernando earthquake originated. Other faults which potentially could cause seismic activity in the City include the Verdugo fault located near the southwest edge of the Verdugo Mountains and its branches to the east, the Sycamore Canyon fault, the Scholl Canyon fault and the Eagle Rock and San Rafael faults. The York Boulevard fault is also important in that it is a western extension of the Raymond Hill fault for which there is considerable evidence for recent geologic activity.

Said faults are generally considered major Southern California earthquake faults which may experience rupture at any time. This amendment establishes grading standards that are intended to improve the performance of graded sites that may be subjected to seismic movement, including both vertical and lateral ground surface acceleration. Thus, because the City is within a seismic area which includes earthquake faults within and through the jurisdictional limits of the City, the modifications and changes cited herein are necessary to better limit personal injury and property damage as a result of seismic activity and to establish criteria for repair of damaged property following a local emergency.

G. This amendment is justified on the basis of a local climatic condition. The seasonal climatic conditions during the late summer and fall create severe fire hazards as hot, dry weather in combination with Santa Ana winds frequently result in wildland fires in the thousands of acres of brush-covered slopes in the Verdugo and San Rafael Hills, Chevy Chase Hills and Repetto Hills areas of the city, which can rapidly denude natural vegetation. The City of Glendale is also subjected to heavy seasonal rains, which are generally more intense than most regions in California. The City’s orientation within the Verdugo Mountains results in a concentration of rainfall during the fall and winter seasons, which often result in severe ground and slope saturation. The City is situated on the alluvial flood plains of the Arroyo Verdugo Wash, Sycamore, Verdugo and Scholl Canyons and the Verdugo and San Gabriel Mountain drainages which have an extensive history of slope failures causing serious floods and mud slides especially when a heavy rainy season occurs after a severe brush fire. New construction and additions in said areas must be regulated to assure that hillside slides will not be exacerbated, and if possible, will be improved. 419
EXHIBIT 1
425 of 518

D:\Exhibit 1\Attachment 15_GBSC_2023_Key to Justification for Amendments.doc 3 H. This amendment is justified on the basis of a local topographic condition. The City of Glendale is situated in an area of significant hillside terrain, which includes areas that are very steep and prone to both surficial and deep-seated slope failures. The topography of portions of the City of Glendale include steep, continuous slopes that are several hundred feet in height, and extend across multiple parcels including privately owned property as well as public right-of-way and publicly owned open space. The topography in many areas is too steep to support significant vegetation, and is prone to erosion during seasonal heavy rains. Other portions of Glendale include lower elevation topography that is located in close proximity to natural waterways which result in high water table conditions. Such topography is typically associated with liquefaction-prone property, and many such regions have been identified on the state’s Seismic Hazard Maps as candidates for potential liquefaction activity.

I. This amendment is justified on the basis of a local climatic condition, which makes amendment of Green Building Standards reasonably necessary pursuant to Health and Safety Code (HSC) 17958.5. The seasonal hot, dry weather during the summer combined with arid conditions throughout the Los Angeles Basin region (including regional drought conditions), contribute to excessive energy demand to support cooling loads. Such conditions also contribute to a regional shortage of potable water supply. Similarly, periods of extremely cold weather during the fall and winter seasons result in significant heat loss in and around buildings.

J. This amendment is justified on the basis of a local topographic condition, which makes amendment of Green Building Standards reasonably necessary pursuant to Health and Safety Code (HSC) 17958.5. The mountainous terrain that surrounds the Los Angeles Basin region contributes to the thermal inversion of trapped air.

Such air becomes atypically warm or cold, depending on the season, thereby significantly increasing energy and water consumption. Furthermore, the thermal inversion traps all forms of air pollution, especially exhaust from hydrocarbon combustion (such as vehicle exhaust), and creates unhealthful respiratory conditions on a frequent basis.

1 GLENDALE BUILDING AND SAFETY CODE, 2023
(Analysis of amendments to the California Code of Regulation)

Introduction

The Glendale Building and Safety Code is comprised of ten (10) distinct volumes as follows:

Volume IA: Building Standards (For Commercial and Multi-Family Residential) Volume IB: Residential Standards (For One-and-Two Family Dwellings and Townhouses) Volume IC: Existing Building Standards
Volume II: Plumbing Standards
Volume III: Mechanical Standards
Volume IV: Electrical Standards
Volume V: Housing Standards
Volume VI: Fire Standards
Volume VII: Security Standards
Volume VIII: Commercial and Industrial Property Maintenance Standards Volume IX: Green Building Standards

The regulatory requirements contained within the first six (6) volumes and Volume IX contained within the California Code of Regulations (CCR), specifically, portions of Titles 19, 24, and 25. The California Building Standards Commission (CBSC) adopted such requirements into the California Building Code, California Residential Code, California Existing Building Code, California Plumbing Code, California Mechanical Code, California Electrical Code, California Fire Code, and California Green Building Standards Code. Adoption and enforcement of the Uniform Housing Code is mandated through the State Housing Law (Health and Safety Code, Division 13, Part 1.5, Section 17960). The 1997 Edition of the Uniform Housing Code was adopted by the California Department of Housing and Community Development as provided for in CCR, Title 25, Division 1, Chapter 1, Subchapter 1, Article 5, Section 32.

Local adoption of such codes is mandated on January 1 , 2023. Prior to such adoption, jurisdictional
bodies may amend said codes if such amendments are justified on the basis of a local climatic, local geologic or local topographic condition which makes such amendment(s) necessary.

The following summary compares the proposed amendments for the 20 23 Glendale Building and Safety Code with the 2020 Glendale Building and Safety Code, and discusses the reason and justification for each such amendment. Each amendment is identified by the section number used in the proposed ordinance. Many of the proposed amendments have been renumbered to match the revised format of the International Codes upon which several of the California codes are based. 330

This amendment is the same as in the 2014, 2017 and 2020 Glendale Building and Safety Code. This amendment requires 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.

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 12.2.3.1 Exception 3 by limiting the number of stories an d 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 the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Sections 1613.5.4 to match the new code format. This amendment is a revision to Section 12.11.2.2.3 of ASCE 7-10 reference document.

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 fl exible 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 appropr iate 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 concre te or masonry walls.

The inclusion o f 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 amendment establishes design parameters to mitigate the increased seismic forces which are imparted upon structures located on sloping surfaces.

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 section is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Section 1613.7 to match the new code format.

This amendment is necessary to address the design of suspended ceilings for seismic loads similar to what is in the current California Building Code. 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 amendment complements ASCE 7 -10 Chapter 13 Section

13.5.6.2.2 and the cited reference to ASTM E580. The amended requirements reta ined herein are a continuation of portions of an amendment adopted during the previous code adoption cycles .

This amendment is the same as in the 2008, 2011, 2014, 2017 and 2020 Glendale Building and Safety Code, renumbered from Sections 1704.6.1 to match the new code. This amendment clarifies an exception regarding structural observation for single family dwellings.

With the higher seismic demand placed on buildings and structures in this region, the language in Section 1704.6.1 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.

This amendment requires special inspection for concrete with a compressive strength over 2500 psi as our code currently requires. Results from studies after the 1994 N orthridge Earthquake indicated that significant 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.

No substantiating data has 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.

This amendment eliminates the use of single top plate construction to maintain the structural integrity of the framing of shear wall systems for building and structures subject to high seismic loads.

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 potenti al 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.

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 0, D1 and D2 unless it
can be substantiated by cyclic testing.

Section VI – 2

7. 903.2.21 Where required
This amendment is the same as the 2020 Glendale Building and Safety Code reflecting Glendale’s fire sprinkler ordinance for both new and existing buildings originally adopted in 1989. Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of earthquake -induced fires. Climatically, seasonal Santa Ana wind conditions have the potential to exacerbate fire conditions, thereby placing a higher degree of reliance upon automatic fire sprinkler systems to assist in the early abatement of structure fires. Topographically, portions of Glendale are located within hillside areas that are accessible by steep, narrow and winding streets, which can delay the arrival of fire suppression resources; automatic fire sprinkler systems can provide early suppression until fire suppression resources can arrive on scene. All of these conditions contribute to the need for increased fire sprinkler standards.

This amendment also includes administrative procedures for notification and enforcement. (Justification: Administrative, Geologic, Climatic , Topographic)

Section VI – 2

7. 906.8 Cabinets
This amendment is the same as the 2020 Glendale Building and Safety Code. This amendment establishes administrative standards for the placement of fire extinguisher cabinets, to ensure that fire extinguishers are located in cabinets to ensure location control of fire extinguishers. The height provision contained in the amendment is intended to coordinate with disabled access provisions to ensure fire extinguishers are accessible to individuals with physical disabilities. This amendment is administrative and does not affect any building standards.

9. 907.6.6 Monitoring
This amendment is essentially the same as the 2020 Glendale Building and Safety Code with a revision to further ensure the reliability of fire alarm monitoring systems by requiring monitoring systems to comply with NFPA 72’s provisions for central station monitoring service, a more reliable and accountable monitoring method. This amendment is administrative and does not affect any building standards.

Section VI-29 is also related to this amendment.
(Justification: Administrative)

Section VI – 3

0. 907.11 Certification and Identification of Certificated Systems This amendment is essentially the same as the 2020 Glendale Building and Safety Code with revised language to clarify requirements related to alterations of existing fire alarm systems. This amendment originally appeared in the 1989 Glendale Building and Sa fety Code and has remained essentially the same in all editions since. This amendment establishes an administrative requirement that all new fire alarm systems, and certain existing systems, such as those that have proven to be unreliable or undergo extensive alteration, to be certificated with a nationally recognized testing laboratory and to have maintenance contract in force. This amendment is related to Section VI -28. (Justification: Administrative)

Section VI – 3 1.

5. Chapter 49 - 4901.3 Liability for damage – 4907.510 Method of Collection The amendment is the same as the 2020 Glendale Building and Safety Code. This amendment provides the implementation, administration and enforcement provisions of Chapter 49, the chapter elated to the High Fire Hazard Area. Glendale is located in a region that has a seasonally dry climate, which often experiences strong Santa Ana wind conditions. The wildland -urban interface fire areas are located in areas of the city where steep, hillside topography increase the difficulty in addressing wind -driven fire events.

5707 On-demand mobile fueling operations
This amendment contains the safety provisions for mobile fueling operations that dispense Class I, II and III liquids into the fuel tanks of motor vehicles.
(Justification: Administrative)

Section VI – 3

7. Appendix B, Table B105.2, Required fire flow for buildings other than one - and two-family dwellings, group R-3 and R-4 buildings and townhouses
This amendment is the same as the 2020 Glendale Building and Safet y. This amendment revises the model code’s reduction of fire flow from 75% to no more than 50% for buildings other than one - and two- family dwellings. Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of earthquake-induced damage to municipal water supply lines. Additionally, large magnitude seismic events often result in loss of power at water distribution pump stations, thereby interfering with water pressure throughout the city. The proposed amendment requires a greater fire flow requirement for buildings other than one- and two-family dwellings, thereby increasing the likelihood of adequate water supply to fight fires after a major seismic event that compromises the municipal water supply.
(Justification: Geologic)

Section VI – 3

8. Appendix C, Table C102.1, Required number and spacing of fire hydrants This amendment is the same as the 2020 Glendale Building and Safety Code which establishes fire hydrant spacing requirements, with some minor editorial clarifications. The amendment requires the average spacing between fire hydrants to be closer than permitted by the model code. Geologically, the City of Glendale is exposed to a high degree of seismicity that increases the likelihood of ear thquake- induced damage to municipal water supply lines. Additionally, large magnitude seismic events often result in loss of power at water distribution pump stations, thereby interfering with water pressure throughout the city. The proposed amendment re quires a closer spacing of fire hydrants, thereby resulting in better access to water to fight fires after the municipal water supply is compromised after an earthquake.

Re: Ordinance # 5998 - Partial

Dear Mr. Sargsyan:

The purpose of this letter is to provide the determination of the California Building Standards Commission (CBSC) following review of the ordinance referenced above with express findings received from City of Glendale on 12/15/22.

Our review finds the submittal to contain one ordinance modifying provisions of the 2022 California Building Standards Code, Title 24, California Code of Regulations (Title 24), including express findings and expressly marked modifications in compliance with Health and Safety Code (HSC) Sections 17958.7 and 18941.5. The code modifications are accepted for filing with the exception of Part 2 2022 California Building Code, Section IA-38, Table 1004.1.2. IA-39 Table 1006.2.1, IA-73 Section 2113.1, IA-104 Appendix F and Part 10 California Existing Building Code Appendices A4 and A6. Please review and provide findings for the aforementioned code sections to obtain a complete filing. This letter attests only to the satisfaction of the cited law for filing of expressly marked local code amendments supported by express findings with CBSC.

CBSC is not authorized by law to evaluate the merit of the findings.

Local modifications to the code are specific to each edition of the code. Local modifications must be readopted and filed with CBSC for each subsequent triennial edition of the code to remain in effect.

Additional information: Fire Protection District ordinances making modifications to Title 24, HSC Section 13869.7 requires such ratified ordinances and express findings to be filed with the Department of Housing and Community Development, Division of Codes and Standards, State Housing Law Program, rather than CBSC. Ordinances making modifications to the energy efficiency and conservation provisions in the California Energy Code, Part 6 of Title 24, may require approval from the California Energy Commission pursuant to Public Resources Code Section 25402.1(h)(2).

If you have questions or need further information, you may contact me at (916) 263-0916.

Sincerely,
Beth Maynard
