Date Action
City Council directed staff to return with a seismic retrofit program for May 13, 2019 existing soft story buildings (Item 9, see Attachment D).
January 13, 2020 Item continued to January 27, 2020 (Item 8, see Attachment D).
First reading of draft Ordinance No. 737*, Mandatory Seismic Retrofit Program for Existing Wood-Frame Building with Soft, Weak or OpenJanuary 27, 2020 Front Walls. City Council waived first reading, set the second reading for March 23, 2020, and directed staff to hold a public workshop prior to the second reading (Item 10, see Attachment D).
Public workshop held on a Saturday morning at City Hall. After February 22, 2020 providing a brief presentation, City staff addressed comments and questions from participants.
City Council hearing for draft Ordinance No. 737 postponed until further March 23, 2020 notice due to state of emergency related to COVID-19 pandemic. * In 2020, the proposed ordinance was numbered Ordinance No. 737. Since it was never adopted, the ordinance number was retired and the currently proposed ordinance is now Ordinance No. 773.
At the January 27, 2020 City Council meeting, staff was directed to hold a public workshop before bringing the ordinance back to Council for final adoption. As noted in Table 1, a workshop was held on Saturday, February 22, 2020. Approximately 40 people attended, asked questions, and made comments. Workshop participants included representatives from Simpson Strong Tie Co, Inc., a private company and recognized industry leader in construction/seismic retrofitting, and members from Structural Engineers Association of Southern California (SEAOSC), a non-profit organization that stays abreast of current technology and best practices for seismic safety. Thus, various experts from the City and external organizations were available at the workshop to answer technical questions related to structural and seismic retrofits. At the conclusion of the workshop, there were no strong objections to the Program.
In preparation for this revised first reading of the Ordinance, notification letters were mailed to potentially affected owners and tenants on December 15, 2023, and the draft N:\Project Files\2019 (1955- 2029)\1982 Soft Story Buildings\2024 First Reading Mandatory Seismic Retrofit Program

Ordinance No. 773 (Attachment A) was made available on the City website at https://carpinteriaca.gov/city-hall/community-development/building-and-safety/soft-storybuilding-retrofit-ordinance/.
Existing Vulnerable Buildings
Buildings that provide resistance to the destructive forces of earthquakes and aftershocks are an essential component of building safety in Southern California.
Building Codes are periodically updated in order to provide the necessary structural resiliency and to increase occupant safety.
In 1986, California enacted Senate Bill 547 (codified as Government Code Section 8875 et seq.), which required local governments in high seismic areas to inventory unreinforced masonry ("URM") buildings and establish a URM loss reduction program.
Pursuant to this legislation, much of the Southern California region, including the City of Carpinteria, was required to develop a URM retrofit program. In 1989, the City passed Ordinance No. 454 which formally declared URMs to be potential hazards and mandated that all URMs be retrofitted, vacated and boarded, or demolished by August 2007. A well-known local building, The Palms Restaurant, is an example of a URM building that was made safer through retrofit due to the mandatory URM retrofit ordinance. Staff believes that all URM buildings within the City have been removed or retrofitted consistent with Ordinance No. 454.
DISCUSSION
Soft-Story Buildings
Although the mandatory URM retrofit program was successful, there are still other categories of vulnerable buildings which exist throughout Southern California, such as "soft-story buildings." Soft-story buildings are wood-frame buildings with more than one story that typically have extensive ground story windows, garage doors, or open-air spaces (such as covered parking areas) with little or no enclosing solid wall(s). These designs result in a relatively soft or weak lateral load-resisting system in the lower story.
Examples of soft-story buildings include mixed use developments with residential units above large glass-fronted commercial ground floors, or residential units located above N:\Project Files\2019 (1955- 2029)\1982 Soft Story Buildings\2024 First Reading Mandatory Seismic Retrofit Program

carports on the ground level. Soft-story buildings are of particular concern due to inadequate strength and lack of shear walls located at the ground floor. The large openings make the ground floor weaker and less resilient than the stories above, thus making the ground floor more vulnerable to collapse during an earthquake. The 1989 Loma Prieta earthquake in the San Francisco Bay area and the 1994 Northridge earthquake highlighted problems related to soft-story construction practices. Soft-story buildings accounted for significant loss of life and property damage during these earthquakes. Photographic examples of building collapses resulting from earthquake damage to soft-story buildings are provided below.
Most soft-story buildings were constructed between the 1920s and 1970s. Staff has conducted an informal survey and estimates at least 15 soft-story buildings containing approximately 300 residential units exist in Carpinteria. An initial summary of the buildings identified as potential soft-story structures is provided in Table 2.

In 1978, California building code standards pertaining to wood construction were strengthened and thus reduced the seismic risk of soft-story buildings built thereafter.
While there is currently no state mandate to retrofit soft-story buildings, some jurisdictions such as the cities of Los Angeles, Santa Monica, and San Francisco have implemented local mandatory retrofit programs.
The main tool available to local jurisdictions to reduce the risks associated with these structural vulnerabilities is to adopt an ordinance which mandates the strengthening of soft-story buildings through seismic retrofitting. Both California State Law regulating Building Code adoption and California Health and Safety Code Sections 19101 and N:\Project Files\2019 (1955- 2029)\1982 Soft Story Buildings\2024 First Reading Mandatory Seismic Retrofit Program
January 8, 2024
19160 - 19168 authorize local jurisdictions to establish such mandatory seismic retrofit standards, so long as the requirements are justified by local climatic, geological and topographical conditions.
The City has local geological conditions, such as expansive soils and earthquake faults that present unique geophysical hazards and demonstrate the need for such mandatory seismic retrofit standards, including the following:
• Areas with expansive soils and topography that are subject to mudflows, unstable conditions, and liquefaction. Special seismic structural considerations must be in place to provide a reasonable degree of structural integrity for buildings constructed in these areas.
• Earthquake faults which, when active and combined with local liquefaction-prone soil conditions, will impose excessive and unique lateral loads on structures in the City. Special lateral structural design criteria must be implemented to resist loads imposed by such conditions.
• The City is bisected by a major freeway (U.S. Highway 101 ), which is vulnerable to floods or earthquakes that can result in impassable roads and/or collapsed bridges. Consequently, emergency personnel responding to an event may be unduly impeded or delayed in accomplishing an emergency response. Delayed response can be particularly detrimental for buildings or structures that were designed and constructed prior to 1991 without the benefit of current seismic retrofit work having been performed.
Proposed Ordinance Elements
The proposed Ordinance (Attachment A) contains the following elements:
• Applies to existing buildings of wood-frame construction with soft, weak, and/or open-front wall lines where construction permits were applied for before January 1, 1991.
• Exempts single family residences and multiple-family residential parcels containing four or fewer units.
• Requires owners of applicable buildings to have a structural engineer review the building design and recommend retrofit based on provided Seismic Design Guidelines (Attachment B) and to be reported on the provided Screening Form (Attachment C).
• Gives owners six months from notice to secure a report; two years from notice to provide plans and obtain permits, and five years from notice to complete construction.
• Allows for reasonable time extensions.
• Requires tenants and occupants to be notified of likely duration of construction.
N:\Project Files\2019 (1955- 2029)\1982 Soft Story Buildings\2024 First Reading Mandatory Seismic Retrofit Program
January 8, 2024
• Specifies retrofit minimum standards which are further articulated in the Seismic Design Guidelines.
• Addresses potential for non-compliance with development standards. • Details plan requirements which are further articulated in the Seismic Design Guidelines and on the Screening Form.
Potential Impacts on Owners, Tenants and Occupants
• Cost of Retrofit. The cost of retrofitting a soft-story building will vary depending on several factors, including age and condition of the building, number of stories, and existing structural integrity. Although the costs of retrofitting are difficult to estimate, several cities, such as Los Angeles, Santa Monica, West Hollywood, San Francisco and Berkeley have generally estimated retrofit costs as ranging from $40,000 to $200,000 per building.
Some resources available to building owners to finance such retrofits include:
o The California Capiiai Access Program (CaiCAP) - Administered by the California Pollution Control Financing Authority (CPCFA), CalCAP's Seismic Safety Financing Program incentivizes private financing for California small businesses and residential property owners (including multi-unit dwellings and registered mobile homes) to finance the costs of seismically retrofitting existing buildings and homes. It offers loss reserve protection to lenders that underwrite the costs of the property improvements. To participate, building owners obtain cost estimates and permits, then reach out to participating lenders. Loans up to $250,000 can be enrolled for a maximum of 10 years under this CalCAP program. o California Multifamily Seismic Retrofit Matching Grant Program - Currently under development, this program will offer seismic retrofit grants to building owners of multi-family (5 to 10 units) soft-story apartment and condominium buildings that have not been previously retrofitted. The program is managed by the California Residential Mitigation Program (CRMP).
o Two other CRMP residential earthquake retrofit grant programs, Earthquake Brace+ Bolt (up to $3,000) and Earthquake Soft-Story (up to $13,000), currently help protect single-family homes in California. • Tenant Displacement During Repairs. Although it is anticipated that most retrofits can be completed without the need to relocate tenants, it is possible that some retrofits may be so extensive that tenant relocation will be necessary. In those circumstances, the property owner(s) would be solely responsible for making arrangements for tenant relocation and any associated costs in compliance with N:\Project Files\2019 (1955- 2029)\1982 Soft Story Buildings\2024 First Reading Mandatory Seismic Retrofit Program
January 8, 2024
CMC Chapter 7.04 ("Just Cause for Termination of Residential Tenancy") and State Law (e.g., Civil Code, § 1946.2), as applicable.
• Time Period for Completion of Repairs. Because this is not a state-mandated retrofit, the time period for completion of repairs is solely up to the discretion of the City. Staff recommendations for timing are provided in Table 3.

• Exemptions to Required Retrofit. Because it is not a state-mandated program, the City has discretion in determining whether to exempt certain structures from the retrofit requirement. Staff recommends single family residences and multiplefamily residential parcels containing four or fewer units be exempted from the requirements of this ordinance. This approach would allow the City to address the most vulnerable, highest occupancy structures in the near term. • Possible Loss of Parking Spaces. Depending upon the design of the retrofit and the existing siting of the building, the required retrofit could result in parking deficiencies. Staff is recommending that the ordinance allow parking reductions to be granted in order to accommodate such retrofits if needed.
Soft-story Retrofit Program Development
As expected in disaster mitigation, most existing programs have been put in place in response to the occurrence of a damaging earthquake. Most of the URM ordinances were enacted in response to a State law that was itself triggered by two deaths in URMs in the 1983 Coalinga earthquake. The Northridge earthquake led to several measures to address soft first-story,' non-ductile concrete and steel moment frame buildings. There is a third wave of programs in the last few years that for the first time are not tied to a recent earthquake. Severallarqe cities, San Francisco, Los Angeles, Santa Monica, West Hollywood, Alameda; Berkeley, and Fremont, have taken action, successfully adopting mandatory soft-story retrofit programs with community support, and other jurisdictions have taken notice.
Staff believes it is appropriate to adopt a seismic retrofit program ordinance for softstory buildings in the city of Carpinteria. The program acknowledges the reality that exists within our region for earthquake preparedness and proactively seeks to strengthen existing older buildings and enhance the security and safety of their occupants. Such a program also seeks to help preserve valuable housing stock in the city where as many as 300 units contained within soft-story buildings are potentially vulnerable.

POLICY CONSISTENCY
General Plan/Coastal Plan
Adoption of local regulations addressing vulnerable buildings and requiring seismic retrofits to soft-story buildings can be found to be consistent with the intent of the following General Plan/Coastal Plan Safety Element Objective and Policy:
Objective 5-1: Minimize the potential risks and reduce the loss of life, property and the economic and social dislocations resulting from fault surface rupture in the planning area, from ground shaking due to an earthquake along a fault in the planning area or in the region, from seismically-induced liquefaction in the planning area, and from seismically-induced tsunamis.
Policy S-1a: Seismic design criteria for habitable building structures, including critical facilities, should utilize the maximum credible earthquake calculated for each of the faults mentioned above, as well as the distance from the building site to each fault, to calculate or determine maximum ground acceleration.
Adopted Housing Element for 2023-2031
The City's adopted Housing Element includes goals and policies addressing the conservation and rehabilitation of existing housing stock. The mandate for seismic retrofits to soft-story buildings can be found to be consistent with the intent of the following goals and policies:
PROGRAM CATEGORY #4 - Conserve and Improve the Condition of the Existing Stock of Affordable Housing
Goals
• Conserve existing housing important to the community such as rental apartments, mobile home parks and other affordable housing units.
• Maintain the affordability of existing and future affordable housing developments. • Attain a housing supply free from substandard and deteriorated housing conditions.
Policies
• Maintenance and Repair. Promote the maintenance and repair of owner-occupied and rental housing to prevent deterioration within the City. • Housing Rehabilitation: Facilitate the rehabilitation of substandard and deteriorated housing where feasible.
• CDBG Rehabilitation: Facilitate the allocation of CDBG funds to multi-family rehabilitation programs and retrofitting of existing housing.

City of Carpinteria Ordinance No. 454
Following Ordinance No. 454 adopted by the City Council in 1989 addressing potentially hazardous unreinforced masonry buildings, this current Ordinance No. 773 addresses potentially hazardous soft-story buildings. Staff will continue to monitor the status of all vulnerable buildings and bring forward plans to address them as they are identified.
State Health and Safety Code
Within Section 19160 of the California Health & Safety Code, the State Legislature declared that because of the generally acknowledged fact that California will experience moderate to severe earthquakes in the foreseeable future, increased efforts to reduce earthquake hazards should be encouraged and supported. California Health and Safety Code Section 19161 authorizes each city, city and county, or county to assess the earthquake hazard in its jurisdiction and to identify buildings that are potentially hazardous to life in the event of an earthquake. Health and Safety Code Section 19162 authorizes the governing body of any city, city and county, or county to establish by ordinance seismic retrofit standards for these buildings.
California Environmental Quality Act (CEQA)
The proposed amendment is exempt from CEQA pursuant to CEQA Guidelines Sections 15301 and 15302. Class 1 (Section 15301 - Existing Facilities) provides an exemption for repair, maintenance, or minor alteration of existing public or private structures involving negligible or no expansion of use. Under the proposed regulations, there would be no expansion of use, as the required retrofits would be limited effecting minimal alterations to the building intended to enhance structural integrity. Class 2 (Section 15302 - Replacement or Reconstruction) provides for replacement or reconstruction of existing structures and facilities where the new structures will be located on the same site as the structures replaced and will have substantially the same purpose and capacity as the structures replaced. Staff has determined that no unusual ... ·· circumstances or other exceptions set forth in CEQA Guidelines Section 15300.2 preclude use of the section 15301 and 15302 categorical exemptions.
FINANCIAL CONSIDERATIONS
The proposed ordinance amendment will likely result in some cost to the City of an indeterminate amount. The cost of plan review and inspections will be fully recovered through plan check and building permit fees. However, the City will likely subsidize the staff costs for administering the program.

WHEREAS, pursuant to Section 19160 of the California Health & Safety Code, the State Legislature declared that because of the generally acknowledged fact that California will experience moderate to severe earthquakes in the foreseeable future, increased efforts to reduce earthquake hazards should be encouraged and supported.
California Health and Safety Code Section 19161 authorizes each city, city and county, or county to assess the earthquake hazard in its jurisdiction and to identify buildings that are potentially hazardous to life in the event of an earthquake. Health and Safety Code Section 19162 authorizes the governing body of any city, city and county, or county to establish by ordinance seismic retrofit standards for these buildings; and WHEREAS, among the potentially hazardous buildings identified in Health and Safety Code Section 19161 are wood-frame, multi-unit residential buildings constructed before January 1, 1991 having soft, weak or open front wall lines (a "soft-story condition").
In California, significant changes were made to State laws between 1978 and 1991 to address seismic hazards; however, after the 1994 Northridge earthquake, programs to analyze and retrofit soft-story conditions began. These conditions generally arise in a building because the first story has perimeter walls that have large openings for garage doors or windows, has few interior partitions, and/or is constructed of materials that have deteriorated over time; and
WHEREAS, in enacting Health and Safety Code Section 19160 et seq., the State Legislature found that residential buildings with a soft-story condition are particularly vulnerable to severe damage and collapse. Their collapse can ignite fires that threaten trapped occupants and neighbbring buildings in the event of an earthquake and could complicate emergency response. In addition, these buildings are an important component of the State's housing stock that are in jeopardy of being lost in the event of a major earthquake. Soft-story residential buildings were responsible for 7,700 of the 16,000 housing units rendered uninhabitable by the 1989 Loma Prieta earthquake and over 34,000 of the housing units rendered uninhabitable by the 1994 Northridge earthquake; and
WHEREAS, in subsections (I) and (n) of Health and Safety Code Section 19160, the Seismic Safety Commission recommended to the State Legislature that any mandatory mitigation programs adopted significantly reduce unacceptable hazards in buildings by 2020 and the Legislature stated its intent that local jurisdictions be encouraged to address the seismic safety of soft-story residential buildings and to initiate efforts to reduce the seismic risk in these vulnerable buildings; and Ordinance No. 773
WHEREAS, Health and Safety Code Section 17958.5 authorizes the City to make changes or modifications to the California Building Standards Code when reasonably necessary because of local climatic, geological or topographical conditions; and WHEREAS, proposed soft story Ordinance No. 773 is reasonably necessary because of local climatic, geological or topographical conditions that exist within the City of Carpinteria, which include but are not limited to: earthquake faults, potential for liquefaction, potential for flooding, expansive soils and topography with potential for mudflows. Further, localized earthquakes may occur in areas with liquefaction-prone soil conditions to impose excessive and unique lateral loads on structures in the City; and WHEREAS, the City's unique geological and topographical conditions, including but not limited to its proximity to a seismically active region of California with onshore and offshore faults and Quaternary age alluvium, colluvium, eolian and beach deposits, call for special lateral structural design criteria to be implemented to provide a reasonable degree of structural integrity for buildings; and
WHEREAS, consistent with the City of Carpinteria's certified General Plan/Local Coastal Plan Objective S-1, the City aims to, "Minimize the potential risks and reduce the loss of life, property, and the economic and social disiocations resulting from fauit surface rupture in the planning area, from ground shaking due to an earthquake along a fault in the planning area or in the region, from seismically-induced liquefaction in the planning area, and from seismically-induced tsunamis"; and
WHEREAS, Program Category 4 of the City's adopted Housing Element includes goals and policies that call for conserving and rehabilitating existing housing stock important to the community such as rental apartments, and attaining a housing supply free from substandard and deteriorated housing conditions; and WHEREAS, the City Council originally initiated, at a duly noticed public hearing on May 13, 2019, the amendment to Carpinteria Municipal Code Chapter 15.70 - BUILDING SEISMIC SAFETY concerning vulnerable buildings and seismic retrofitting of soft-story buildings. On January 27, 2020, the City Council subsequently considered draft Ordinance 737 (Mandatory Seismic Retrofit Program for Existing Wood-Frame Buildings with Soft, Weak or Open-Front Walls) and voted (4-1-0) to waive the first reading, set the second reading for March 23, 2020, and have the City conduct a workshop; and WHEREAS, the City noticed and held a public workshop on Saturday, February 22, 2020, to present detailed information related to soft-story retrofits and the potential requirements of draft Ordinance 737. Approximately 40 people attended the workshop, including tenants and owners of identified soft-story buildings as well as experienced contractors who provide retrofit services. The workshop concluded after all participants had an opportunity to ask questions and provide comments; and WHEREAS, the City Council canceled the second reading of Ordinance 737 on March 23, 2020, due to the state of emergency related to the COVID-19 pandemic. In March of 2021, ordinance number "737" was retired and the Mandatory Seismic Retrofit Ordinance No. 773
Program for Existing Wood-Frame Buildings with Soft, Weak or Open-Front Walls was placed on hold; and
WHEREAS, in December of 2023 the City revised the Mandatory Seismic Retrofit Program for Existing Wood-Frame Buildings with Soft, Weak or Open-Front Walls that was placed on hold and mailed notices to tenants and owners of identified soft-story buildings on December 15, 2023 informing them of the revised first reading of soft story Ordinance No. 773 by the City Council; and
WHEREAS, the City Council finds that proposed soft story Ordinance No. 773 shall require retrofit of existing buildings consistent with a nationally recognized model code or substantially equivalent standards in accordance with subdivision (b) of Health and Safety Code Section 19163; and
WHEREAS, the City Council finds that it is in the interest of the orderly development of the City and important to the preservation of the health, safety, and general welfare of the residents of the City, to adopt an ordinance adding Chapter 15. 72 ("Mandatory Seismic Retrofit Program for Existing Wood-Frame Buildings with Soft, Weak or OpenFront Walls") to Title 15 (Buildings and Construction) of the Carpinteria Municipal Code ("CMC") to address existing buildings that are particularly vulnerable to seismic-induced hazards ..

15.72.010 Purpose.
The provisions of this Chapter are intended to promote the public health, welfare and safety by reducing the risk of death or injury that may result from the effects of earthquakes on existing wood-frame multi-story buildings with Soft, Weak or OpenFront Walls. Generally, this type of structure consists of partial tuck-under parking on the first floor level with living space in the floors above. In past earthquakes, many of these types of structures have performed poorly and collapsed causing loss of life, personal injury, and substantial property damage. This Chapter creates minimum standards intended to reduce the risk of collapse and improve the performance of these buildings during earthquakes, facilitate post-earthquake emergency response, minimize displacement during retrofits and reduce economic impacts of a damaging earthquake, but not necessarily prevent the loss of life, injury and damage to property.
15.72.020 Applicability.
A. The provisions of this Chapter shall apply to all existing buildings of wood-frame construction, or wood-frame portions thereof, where:
1. A permit for construction of a new building was applied for before January 1, 1991, or the building was designed based on an adopted version of the 1985 or earlier edition of the Uniform Building Code and contains five (5) or more dwelling units and have a wood frame target story. If no permit can be located, the structure is determined by the Building Official to have been built under Building Code standards enacted prior to January 1, 1991, and
2. The ground floor or basement portion of the structure contains parking or other similar open floor space that causes soft, weak, and/or open-front wall lines.
B. Exceptions. The provisions of this Chapter shall not apply to:
1. Single family residences.
2. Multiple-family residential parcel containing four (4) or fewer units.
3. Ground floor or basement concrete podium levels where a rigid concrete diaphragm exists, however the first wood-frame story above the podium shall be subject to the provisions of this chapter where soft, weak, or open-front walls exist.
Ordinance No. 773
C. Notwithstanding any provision of the Building Code, compliance with this Chapter shall not require existing electrical, plumbing, mechanical or fire-safety systems to be altered to comply with the current Building Code unless they constitute a hazard to life or property as determined by the Building Official.
15.72.030 Definitions.

1. BUILDING CODE. The current Building Code of the City of Carpinteria.
2. CRIPPLE WALL. A wood-framed stud wall extending from the top of the foundation wall to the underside of the lowest floor framing.
3. GROUND FLOOR. Any floor within the wood-frame portion of a building whose elevation is immediately accessible from an adjacent grade by vehicles or pedestrians. The ground floor portion of the structure does not include any floor that is completely below adjacent grades.
4. HISTORICAL BUILDING. Any building designated as a "qualified historical building" as defined in Part 8, Title 24 of the California Code of Regulations (also referred to as the "California Historical Building Code"). · 5. NOTICE TO OWNER. The letter sent by the City to Owner, via certified mail to the address on title of the property, which advises Owner of the retrofit requirement.
6. OPEN-FRONT WALL LINE. An exterior Wall Line, without vertical elements of the lateral force-resisting system, which requires tributary seismic forces to be resisted by diaphragm rotation or contains an excessive cantilever beyond parallel lines of shear walls. Diaphragms that cantilever more than 25 percent of the distance between tines of lateral force resisting elements from which the diaphragm cantilevers shall be considered excessive. Diaphragm cantilevers or exterior balconies of 6 feet or less in width shall not be considered excessive cantilevers.
7. OWNER OR BUILDING OWNER. The individual(s), firm, corporation, trust or entity in whom the title to such property is vested.
8. PERSON. An individual, partnership, corporation, association, or any other entity.
9. RETROFIT. An improvement of the lateral force resisting system by alteration of existing structural elements or addition of new structural elements.
10. CITY SEISMIC DESIGN GUIDELINES. Framework guidelines developed by the City's Building Official which are intended to calibrate, delineate, and detail technical requirements to be used for the retrofitting of buildings subject to this Chapter.
11. SOFT WALL LINE. A deficiency in a Wall Line in which the lateral stiffness is less than what is required by story drift limitations and deformation compatibility requirements of this Chapter. In lieu of the engineering analysis required by this Ordinance No. 773
Chapter to determine whether a wall line's lateral stiffness is less than the aforementioned story drift limitations and deformation compatibility requirements, a Soft Wall Line deficiency may be defined as a Wall Line in a Story where the wall stiffness is less than 70 percent of the stiffness of the exterior wall above for the direction under consideration.

SEISMIC DESIGN GUIDELINES
FOR EXISTING WOOD-FRAME BUILDINGS WITH SOFT, WEAK OR OPEN-FRONT WALLS Retrofit Scope
The intent of ordinance is to reduce the risk of full or partial collapse in multi-story wood building containing exterior Soft, Weak, or Open-Front Walls (SWOF) lines. The ordinance therefore mandates the evaluation and possible strengthening of exterior SWOF lines around the building. The City has identified buildings that typically contain these SWOF lines. The minimum strengthening required to meet the intent of the ordinance is as follows:
• Where needed, evaluate and strengthen the soft, weak, and open-front wall lines by providing new lateral force resisting system(s). The connections to the floor diaphragm directly above the new lateral force resisting system(s) and the foundation of the new system must be included in the design. Where existing diaphragms ratios exceed 3:1, the existing diaphragm should be shown to be adequate, strengthened if needed or new lateral force resisting lines should be added.
• he first page of the retrofit drawings shall include a statement that clearly identifies the scope, design criteria, and extent of the retrofit.
Design Methods
The retrofit shall meet the strength and stiffness prescribed herein including the following considerations:
• The lateral-load-path analysis shall include the resisting elements and connections from the wood-frame diaphragm immediately above any soft, weak, or open wall lines and down to the foundation. • Stories above the weak wall line shall be considered in the analysis but need not be modified. • Wall lines along parking or similar open space shall be evaluated to determine the soft, weak, or open-front wall lines.
• Weakening the existing lateral force resisting system above the weak line shall not be permitted as a form of meeting the ordinance.
Analysis & Design Parameters
• Building Design Base Shear. The minimum design base shear for buildings, including Historical buildings, shall be 75 percent of the value specified in ASCE 7-10 Section 12.8.1. • Response Modification Factor, R. The value of R shall be per ASCE 7-10 Table 12.2-however, the value of R used in any direction shall not exceed the value at any story above, in the same direction per ASCE 7-10, 12.2.3.1.
Exceptions:
o R need not be less than 3.5, provided the lateral force resisting system R Value as listed in ASCE 7-10, Table
12.2-1 are not less than 3.5.
o R values greater than 3.5 shall meet the following requirements:
i. Retrofit shall mitigate the soft or weak wall line as defined in the ordinance. ii. The design professional shall perform additional investigation on the walls above the new system to prove the existing materials and details meet the requirements of ASCE 7-10, Table 12.2-1 for the proposed R value. Investigation shall be documented and submitted to the Building Official for review and approval.

SEISMIC DESIGN GUIDELINES
FOR EXISTING WOOD-FRAME BUILDINGS WITH SOFT, WEAK OR OPEN-FRONT WALLS • Seismic Weight. Following loads shall be considered as the minimum unless shown otherwise:
o 10 psf for partition loads per ASCE 7-10 Chapter 12
o 15 psf minimum roof dead load or provide detailed dead load calculation o 15 psf (+8 psf for stucco soffit cover in parking area as applicable) minimum floor dead load or provide detailed dead load calculation
o 15 psf exterior wall weight, per sf of wall, or provide detailed exterior wall dead load calculations o +15 psf for floor dead load due to existing concrete topping, if applicable o +5 psf for existing solar panels on the roof as applicable • Redundancy Factor, p. p shall be 1.3 unless the criteria in ASCE 7-10 Section 12.3.4.2 is met for the line being strengthened. For drift calculation, members, and connection design loads using overstrength factor, p shall be
1.0. • Importance Factor shall be equal to 1.0 for all residential buildings. • Vertical Distribution of Seismic Forces over the height of the structure shall be based on ASCE 7-10 Section 12.8.3. • Story Drift Limitations. The calculated story drift for each retrofitted story line shall not exceed the allowable deformation compatible with all vertical load-resisting elements and 0.025 times the story height. Where a cantilever column system utilizes pole footings or single spread footings, soil interaction shall be considered when determining the drift.
• Deflection Amplification Factor, Cd, and the Overstrength Factor, Oo, shall be as follows:
o For Lateral Force Resisting Systems using an R value equal to 3.5:3.0 and 3.0, respectively. o For All other Lateral Force Resisting Systems: values as listed in ASCE 7-10, Table 12.2-1. • P-Delta Effects shall be considered for new lateral force resisting systems using the tributary area to the system.
Where a cantilever column system utilizes pole footings or single spread footings, soil interaction shall be considered when evaluating P-delta effects.
• Deformation Compatibility. All structural framing elements and their connections not required to be part of the lateral system, shall be adequate to maintain support of design dead and live loads when subject to expected deformation of seismic loads. Focus should be placed on the existing columns/post along the retrofit line to ensure they are positively attached so they can maintain support of the vertical gravity loads during a seismic event. Deformation compatibility shall also be satisfied for the vertical elements of the new lateral force resisting systems which rely on fixity at the base connection. To satisfy this requirement, the vertical elements of the lateral force resisting system shall be connected to the diaphragm and designed for the forces associated with the drift in the perpendicular direction to the line of strengthening. Unless a full building analysis is performed to determine drift demands, a three percent drift demand shall be assumed. The analysis may account for flexibility in the foundation and connection.

Previous City Council Meeting Minutes
Seismic Retrofitting of Soft-Story Buildings
January 8, 2024 City Council Meeting
Minutes from Three Previous City Council Hearings Related to Seismic Retrofit Program for Existing Wood-Frame Buildings with Soft, Weak, or Open-Front Walls
May 13, 2019 - Initiation of Program (Item 9)
9. Initiation of City regulations concerning Seismic Retrofitting of Soft-Story Buildings.
Recommendation: Based on the options described in the staff report, initiate amendment to the Carpinteria Municipal Code Chapter 15.70 - BUILDING SEISMIC SAFETY concerning vulnerable buildings and seismic retrofitting of soft-story building.
Dan Chepley, Building Inspector/Plans Examiner, presented the staff report and PowerPoint presentation.
Councilmember Shaw inquired regarding prioritizing buildings for seismic retrofitting.
Steve Goggia, Community Development Director, responded that potential soft-story buildings would be identified and letters would be sent to the owners to ask that they take part in the process. He stated that the owners would be asked to seek an assessment from a registered architect or engineer to develop a plan within a certain timeframe if their buildings are found to be defective and need to be retrofitted. He also stated that all of the ·15 soft-story buildings in the city would be considered at the same time. Dave Durflinger. City Manager, added that the City Council could prioritize one group of properties over another. He noted that staff's recommendation would be to have a uniform standard due to the number of buildings to be retrofitted.
Councilmember Carty inquired whether it would be the property owner's responsibility to seek a registered architect or engineer. Mr. Chepley responded that the property owner would need to seek an engineer at their cost to provide an assessment on whether the building meets the criteria of the retrofit program. Councilmember Carty expressed concern with the projected cost estimates for retrofitting soft-story structures.
Mr. Chepley addressed the importance of assessing structures for seismic vulnerability; current building standards for new soft-story buildings; potential impacts to the property value if a building is identified as a soft-story structure; possible exceptions should a future State mandate come after a city-imposed ordinance; and consequences to property owners should they not comply with the guidelines which could include a lien against the property and possible punitive damages.
Mr. Durflinger referred to the existing Municipal Code Chapter 15. 70. 70 regarding seismically vulnerable buildings, which includes an enforcement and penalty section.
There were no Public Comments.
Motion by Vice Mayor Clark. seconded by Councilmember Shaw, to direct staff to prepare a draft ordinance amending the Carpinteria Municipal Code Chapter 15.70 - Building Seismic Safety, concerning vulnerable buildings and seismic retrofitting of SoftStory buildings.
Upon voice vote, motion carried unanimously.

Ordinance No. 737, an Ordinance of the City Council of th City of Carpinteria, adding to Carpinteria Municipal Code Title 15, Chapter 15. 72, entitled, "Mandatory Seismic Retrofit Program for Existing Wood-Frame Buildings with Soft, Weak or Open-Front Walls. (Continued from January 13, 2020) (Requires reading of ordinance title and roll call vote)
Recommendation: Conduct a public hearing; introduce and waive the first reading of Ordinance No. 737, Mandatory Seismic Retrofit Program for Existing Wood-Frame Buildings with Soft, Weak or Open-Front Walls; set the second reading and adoption for the City Council meeting of February 10, 2020.
Steve Goggia, Community Development Director, and Dan Chepley, Chief Building Inspector/Plans Examiner, presented the staff report and PowerPoint presentation.
Mr. Goggia addressed the environmental impacts and clarified that the work being performed for the seismic upgrades for the buildings would be exempt pursuant to CEQA Guidelines Section 15301. He also requested that the City Council add CEQA Guidelines Section 15060 (c) 3 to the ordinance, which indicates that the activity is not a project as defined in CEQA 15378. He noted the following additional changes to the ordinance: clarify that the ordinance applies to buildings that contain five or more units; a building with four or fewer is an exemption; Section 15.72.060 Administration, a.
Issuance of Notice to Owner, strike out "in accordance with the priorities set forth in Table B''; and Section 15.72.060 Administration, e. Extensions "With the exception of the one-year period ... " should be "With the exception of the six-month period ... " Mr. Goggia and Mr. Chepley responded to a question regarding penalties for violation by referring to Section 15. 72.130, and a question regarding exceptions under Section
17.72.060 of the ordinance in order to gain voluntary compliance.
A discussion ensued regarding the location of soft story buildings in the City; concerns regarding the cost associated with securing certified engineering reports and with Attachment D
seismically retrofitting a soft story building; exploring alternative programs through the Office of Emergency Services; and instances where extensions might be granted.
Mack Car1son, on behalf of Brownstein Hyatt Farber Schreck, LLP acting as City Attorney of the City of Carpinteria, responded to a question regarding any legal Issues associated with the City requiring a mandatory seismic retrofit program when it is not required by the State by stating that the State published Health and Safety Code beginning in Section 19160 in that the Seismic Safety Commission recommended that State Legislation be enacted to require state and local building code enforcement agencies to identify potentially hazardous buildings and to adopt mandatory mitigation programs that would significantly reduce unacceptable hazards by 2020. It is the intent of the legislator to encourage cities and counties to address seismic safety of soft story residential buildings, and encourage local governments to Initiate efforts to reduce the seismic risk in vulnerable soft story residential buildings Additionally, Section 19163 includes specific requirements that should be included In any local ordinance related to seismic retrofit. He stated that although not required under State law, the legislator has acted to encourage local jurisdictions to adopt these types of ordinances.
Mr. Goggia responded to a question regarding impacts from sea level rise policies to soft story buildings.
Mayor Nomura opened the Public Hearing at 6:30 p.m.
Kathy Henry spoke in support of the adoption of Ordinance No. 737.
Bob Beechinor recommended that affected property owners be provided a copy of Ordinance No. 737. He expressed concern with the cost to retrofit soft story buildings Adam Manfredovia inquired regarding what other jurisdictions have put in place for seismic retrofit programs, including costs and funding programs.
Mayor Nomura closed the Public Hearing at 6:47 p.m.
Motion by Councilmember Shaw, seconded by Vice Mayor Clark, to waive the first reading of Ordinance No. 737, Mandatory Seismic Retrofit Program for Existing WoodFrame Buildings with Soft, Weak or Open-F rant Walls; set the second reading and adoption for the City Council meeting of February 10, 2020; Include the changes brought forth by staff; and have the City conduct a workshop.
Dave Ourflinger, City Manager, responded to a question regarding whether the workshop could be held before February 10, 2020, by stating that the City Council could defer enacting the ordinance on first reading and ask staff to conduct workshops and bring back the ordinance: the City Council could adopt the ordinance on first reading and direct staff to hold workshops and come back for the second reading at a later date; or conduct the workshops after adoption of the ordinance. He noted that there was no timeline or mandate from the State to implement the program.
Amended motion by Councilmember Shaw, seconded by Vice Mayor Clark, to have the second reading of Ordinance No. 737 set for the second meeting in March.

ln October 2008, the Carpinteria City Council adopted Ordinance No. 637 (codified as CMC Chapter 8.50) which regulated the distribution of expanded polystyrene (EPS) food containers for take-out at restaurants.
ln March 2012, the City Council adopted Ordinance No. 655, regulating the use of single-use plastic and paper bags. These regulations were successfully implemented in the city with the cooperation of the affected businesses, greatly reducing the number of EPS and single-use bags in the Carpinteria environment and their diversion to landfills.
Chapter 8.50 was amended in 2017 by Ordinance No.719 and Ordinance No. 727 in 2019, further regulating expanded polystyrene and other single-use plastic products to include retail sale products, single-use food ware items, and EPS pdckaging materials Plastic is made of non-renewable petroleum products. When exposed to the elements, it photodegrades, breaking up into smaller and smaller pieces that are difficult and expensive to remove from the environment. These small pieces of plastic debris, known as microplastics, are increasingly found throughout the environment, including in soil, Ordinance No. 776
January 8,2024
water, and airborne. This is of particular concern because microplastics, which are defined as pieces of plastic less than five millimeters in length, have been found in wildlife, domestic food sources, and in the human body and are believed to cause a host of health issues such as reproductive, metabolic and neurodevelopmental hazards.l
Waste reduction mandates have been a strategy of the California Legislature for many years, first starting in 1989 with the lntegrated Waste Management RLt wnicn formed the lntegrated Waste Management Board (now called the Catifornia Department of Resources Recycling and Recovery, ot CalRecycle). More recently, the state has regulated the distribution of single-use bags, used motor oil, and the Plastic pollution and Packaging Producer Responsibility Act (Senate Bill 54), which aims to reduce single-use plastic packaging and shift the plastic pollution burden from the consumer to the producer. Extended producer responsibility regulations like SB 54 have been found to be the most effective way of reducing waste at its source2.
Single-use plastics continue to be challenging to recycle due to a large variation in chemical composition. For instance, polyethylene terephthalate (PEf) plastic botfles are considered a higher grade plastic and are all made from similar high-grade pET plastics, and have a recycling market here in California. High Deniity polyethylene (HDPE) plastics, on the other hand, are considered a lower grade plastic due to the varying chemical composition that makes it difficult to remanufacture into another product. Recycling rates for all plastic remains low, with an estimated 8.5% of all plastics being recycled3. Since 2018, the largest market for recycling, China, has implemented increasingly strict contamination regulations in an effort to reduce pollution. Most plastics are stockpiled, landfilled, or sent overseas, where it may be remanufactured but is often landfilled or incinerated.
Beginning in March 2020 and throughout the Covid-19 pandemic, the City paused enforcing most of its extended producer responsibility regulations, including single-use plastics regulations, in accordance with the provision that implementation of suCh regulations would be suspended during a locally declared emergency. Prior to beginning outreach to businesses to bring them back into compiiance, staff is proposing several updates to the single-use plastics regulations.
On November 15, 2023, staff presented draft updates to the City's existing single-use plastics regulations to the Sustainability Committee in response to recent legislation regulating plastics and was directed to bring forward a draft ordinance with ihose 1 Claudia Campanale et al., A Detailed Review Study on Potentiat Effects of Microptastics and Additives of Concern on Human Health,lnternational Journal of Environmental Research and public Health (February 2020), available at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC706860O/. 2 California Department of Resource, Recovery, Recyciing,'Pla stic Poltution prevention and packaging Producer Responsibility Act SB 54, at https://calrecycle.ci.gov/packaqing/packaqinq-epr/ laccessed on January 2,2023).

January 8,2024
updates incorporated. The purpose of this agenda matter is to present said ordinance amending Chapter 8.50 of the CMC further regulating polystyrene and single-use plastics.
DISCUSSION
Staff is planning an extensive business outreach campaign to take place from January 2024 through June of 2024 to bring businesses back into compliance with existing regulations. ln preparation for that effort, staff is proposing several updates to CMC Chapter 8.50, as summarized below. Some of these changes are to align more closely with new state regulations, while others further the City's efforts to reduce waste from the landfill.
Polystyrene Products
Polystyrene is a light material made of petrochemicals used to make food containers, packaging materials, and disposable ice chests. Polystyrene is a problematic material as it easily enters the environment as litter due to its lightweight and durable nature.
Expanded polystyrene products (often incorrectly referred to as Styrofoam) have a foam structure that easily break into small pieces, making them difficult and expensive to remove from the environment. Rigid polystyrene, often labeled with the recycling code PS or #6, is difficult to recycle, and most foodware items with this label are nonrecyclable. The existing regulations prohibit all expanded polystyrene single-use products.
Revision: Expand the regulations to a prohibition of all polystyrene foodware and packaging material.
Food Service Ware and Condiments (AB 1276)
On October 5,2021, Assembly Bill 1276 was signed into law prohibiting a food facility from providing single-use foodware accessory or standard condiments to a consumer unless requested and those items are prohibited from being bundled or packaged in a way that prohibits the consumer from taking only the item desired.
Revision: Added language regarding bundling and packaging to comply with AB 1276.
Removal of Marine Deqradable (AB 2287)
When the City first adopted these regulations, "marine degradable" was a certification available in California. Assembly Bill 2287 acknowledged no movement on developing the certification and discontinued the "marine degradable" standard.
Revision: Removed the term "marine degradable" from the Ordinance language.
Ordinance No. 776
January 8,2024
Redefine "Compostable" and "Recvclable" (SB 54\
Senate Bill 54, the Plastic Pollution and Packaging Producer Responsibility Act, aims to prohibit materials that are not recyclable or compostable from being distributed in California. To align with these regulations, the definitions of compoiable and recyclable have been updated.
Revision: Redefine "compostable" and "recyclable" to align with SB 54 definitions.
Reusable Foodware (AB 619)
California Health and Safety Code Sections 114121 and 1 14353 were updated in 2019 to allow businesses to use customer-provided reusable containers, as long as the containers are clean and in good condition. Food providers have the discretion to prepare and maintain written procedures, and may provide a discount to customers who provide their own foodware at their discretion.
Reducing single-use materials is the most effective way to address waste and pollution problems, and encouraging local businesses to adopt procedures allowing reusable materials can also encourage behavior change of customers. Coffee shops are an example of businesses that have allowed customers to bring reusable foodware in the form of cups; the intent of including this in Ordinan ce 776 islo encourage local businesses to participate in source reduction on a rarger scare.
Revision: lncorporate amendments to the Catifornia Heatth and Safety Code, ailowing reusable foodware.
Additional ltems for Consideration
While conducting outreach prior to bringing the proposed changes fonrvard for consideration, the City received public comment regarding regulating mylar balloons and the release of latex balloons. Balloons, made from latex or the foil-and-polyester material commonly known as Mylar, inflated with helium or another gas lighter ihan air are able to travel long distances and commonly end up in the ocean and waterways.
The environmental impacts of balloon releases pose threats to both marine and landbased species due to the balloons being confused for food and ingested, causing starvationa. Additionally, it is common for balloons to have a stringLd ribbon attaChed which can cause entanglement and strangulations.
ln 1990, California passed Senate Bill 1990, enacting a Balloon Law to regulate the sales and use of helium-filled foil or Mylar balloons in an effort to reduce pbwer outages 4 NOAA Marjne Debris Program Why is Marine Debris a Problem, https://marinedebris.noaa.gov/discovermarine-debris/why-marine-debris-problem 5 U.S. Fish and Wildlife Service Ballons and Wildtife, https://www.fws.gov/story/2o15-08/balloons-andwild life-please-dont-release-vour-balloons Ordinance No. 776
January 8,2024
ln 2008, Senate Bill 1499 was passed to increase the fine for violating the provisions in SB 1990 and required manufacturers or distributors from shipping Mylar balloons to retailers without providing a notice describing the retailer's responsibilities. ln 2018, Assembly Bill 2450 was passed and required a warning to be placed on each balloon about the dangerous risk of fire if the balloon were to come in contact with an electrical power line. Other states with balloon regulations include Connecticut, Florida, Tennessee, and Virginia. Although not required by state law, the California cities of Goleta, Fairfax, and Laguna Beach have prohibited the sale, distribution, and use of all balloons.
Staff has included draft language for consideration under Section 8.50.090 in Ordinance No. 776, which would prohibit the use and distribution of mylar balloons and latex gasfilled balloons.
Revision: Added language prohibiting the distribution of all mylar balloons, as well as the distribution of latex balloons filled with air orgases lighter than air.
Potential lmpacts to Businesses
The most frequently cited impact to businesses is cost. The average cost of a singleuse plastic foodware accessory is between $0.007 and $0.089. The average cost of a single-use plastic alternative foodware accessory is between $0.014 and $0.155 per unit. These costs vary widely between type of foodware accessory and material. lt is expected that reducing the distribution of single-use products would balance the expense of envi ronmental ly friend ly alternatives.
Outreach
An important part of regulating products is working with the local community. Staff gathered input and solicited feedback from the community for these proposed changes via social media posts and the City newsletter, The Currenf. The City currently has a Civicspark Fellow whose primary project is outreach for the Solid Waste and Watershed Management programs. Over the coming months the Fellow will be conducting outreach with local businesses to educate them on the updated regulations for both programs, as well as the resources that the City can provide to help bring businesses into compliance.
POLICY CONSISTENCY
The ordinance amendment is consistent with the City's General Plan6 (Open Space, Recreation & Conservation Element (OSC)/ Public Facilities & Services Element (PF)), 6 https://carpinteriaca.gov/city-hall/community-developmenUplanning/general-plan-coastal-land-use-plan/ Ordinance No. 776
January 8,2024
Sustainable Community PolicyT, and MS4 permitting programs, which direcly reference and aim to reduce waste or encourage recycling and sustainability. These policies are consistent with state laws and regulations intended to reduce the plastic burden on the environment, such as sB s4, AB 1276, and AB 2297, discussed above.
FINANCIAL CONSIDERATIONS
No Additional Funding Requested. Minimal staff time to prepare the report is included in the Adopted FY 2023-2024 Budget. Ordinance No. 776 would add regulations to the Carpinteria Municipal Code. lt is expected that implementation and enfoicement of the regulations would be addressed by existing budgeted resources.
LEGAL AND RISK MANAGEMENT CONSIDERATIONS
The City Attorney's Office has reviewed the agenda materials and will be available to answer questions at the meeting.
