DATE: 11/05/2025

FROM: Planning & Development Department
2025-416
REQUEST FOR CITY COUNCIL ACTION
SUBJECT:
GENERAL PLAN AMENDMENT 2025-0002 TO UPDATE THE WILDFIRE HAZARD
SEVERITY ZONE MAP IN THE PUBLIC SAFETY ELEMENT TO BE CONSISTENT
WITH THE FIRE HAZARD SEVERITY ZONES MAP ISSUED BY THE OFFICE OF THE
STATE FIRE MARSHAL (CITY OF CORONA FIRE DEPARTMENT)
EXECUTIVE SUMMARY:
This staff report asks the City Council to approve General Plan Amendment 2025-0002 (GPA2025-0002), amending the Public Safety Element of the General Plan to update the Fire Hazard Severity Zone (FHSZ) Map. The map was updated by the Office of the State Fire Marshal, and on June 4, 2025, the City Council adopted an ordinance amending Chapter 15.16 of the Corona Municipal Code to adopt the updated FHSZ map. The updated map went into effect on July 4, 2025. GPA2025-0002 establishes consistency with CMC Chapter 15.16 and the map issued by the State Fire Marshal.
RECOMMENDED ACTION:
That the City Council:
a. Approve General Plan Amendment 2025-0002 as recommended by the Planning and Housing Commission.
b. Adopt Resolution No. 2025-105 approving an amendment to the City’s General Plan to update the Wildfire Hazard Severity Zone Map as part of Cycle 3 of General Plan Amendments for calendar year 2025 (GPA2025-0002).
BACKGROUND & HISTORY:
The Office of the State Fire Marshal (OSFM) of the California Department of Forestry and Fire Protection (CAL FIRE) is responsible for identifying Fire Hazard Severity Zones (FHSZ) throughout California. These zones are categorized as Moderate, High, or Very High based on consistent statewide criteria and the expected fire hazard levels in those areas, as required by Government Code 51178. The different severity zones are based on fuel loading, slope, fire weather, and other relevant factors including areas where winds have been identified by the OSFM as a major cause of wildfire spread.
Local Implementation
Chapter 15.16 of the CMC establishes the City’s Fire Hazard Severity Zones. On March 24, 2025, the OSFM released an updated FHSZ map for the City of Corona. This map identifies the Local Responsibility Areas (LRAs) within Corona – areas for which the City is primarily responsible for providing wildfire protection. According to CAL FIRE, the updated map incorporates new scientific data, including member spread patterns and localized climate information, providing a more accurate representation of the areas within the City that are susceptible to wildfire. In addition, the updated map includes designations for Moderate and High zones within the City, whereas the previous version only included the designation for Very High.
Government Code Section 51179 requires local jurisdictions such as the City of Corona to designate, by ordinance, the fire hazard severity zones within 120 days of receiving the updated FHSZ map from the OSFM. On May 14, 2025, the Corona Fire Department held a community meeting on the updated FHSZ map for the City. On June 4, 2025, the City Council adopted Ordinance No. 3418, amending Chapter 15.16 of the CMC to adopt the updated FHSZ map. The updated map went into effect July 4, 2025.
ANALYSIS:
The City’s 2020-2040 General Plan was adopted by the City Council on June 3, 2020.
The General Plan includes a Public Safety Element, which contains the FHSZ map under Figure PS-11. The version currently in the General Plan was in effect at the time of the General Plan’s adoption and must be updated to reflect the version recently issued by the OSFM and adopted by the City Council.
GPA2025-0002 replaces the existing FHSZ map, with the updated map released in 2025.
The map identifies the Moderate (yellow), High (orange), and Very High (red) fire hazard zones within the City’s boundaries, as well as areas outside the boundaries located within the City’s Sphere of Influence (SOI) areas, which include Coronita, Home Gardens, El Cerrito, Temescal Valley, Eagle Valley, and a few other smaller pockets of unincorporated land.
In addition, the updated map distinguishes among the different agencies that have primary responsibility for wildfire protection:
Local Responsibility Areas – Local Agency (City of Corona) State Responsibility Areas – State of California
Federal Responsibility Areas – Federal Government
FINANCIAL IMPACT:
GPA2025-0002 is a City-initiated amendment; therefore, no fees were associated with this application.
ENVIRONMENTAL ANALYSIS:
This General Plan Amendment is exempted from the California Environmental Quality Act (CEQA) pursuant to Section 15061(b)(3) of the CEQA Guidelines, the “common sense” exemption. This exemption applies where it can be seen with certainty that there is no possibility the activity may have a significant effect on the environment. The proposed General Plan Amendment (GPA2025-0002) qualifies, as it merely replaces the existing fire hazard severity zones map (Figure PS-11 of the Corona General Plan) with the updated map issued by the Office of the State Fire Marshal on March 24, 2025, and adopted by the Corona City Council on June 4, 2025.
PLANNING AND HOUSING COMMISSION ACTION:
At its meeting on October 20, 2025, the Planning and Housing Commission considered the subject matter and took the following action:
Motion was made, seconded (Siqueland/Vernon), and carried unanimously with Commissioner Longwell absent, that the City Council find the project exempt from the California Environmental Quality Act (CEQA) and adopt Resolution No. 2674 granting GPA2025-0002 as part of Cycle 3 of General Plan Amendments for 2025. The minutes of the Planning and Housing Commission meeting are included as Exhibit 3.

RESOLUTION NO. 2025-105
RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
CORONA, CALIFORNIA, APPROVING AN AMENDMENT
TO THE CITY’S GENERAL PLAN TO UPDATE THE
WILDFIRE HAZARD SEVERITY ZONES MAP AS PART OF
CYCLE 3 OF GENERAL PLAN AMENDMENTS FOR
CALENDAR YEAR 2025 (GPA2025-0002).
WHEREAS, on March 24, 2025, the City of Corona received from the Office of the State of Fire Marshal a map that identifies the fire hazards severity zones within the City; and WHEREAS, on June 4, 2025, the City Council adopted Ordinance No. 3418, amending Chapter 15.16 (Fire Hazard Severity Zones) of the Corona Municipal Code to adopt the fire hazard severity zones map issued by the Office of the State Fire Marshal; and WHEREAS, on October 20, 2025, the Planning and Housing Commission of the City of Corona (“Planning Commission”) conducted a duly noticed public hearing and recommended that the City Council of the City of Corona (“City Council”) approve GPA2025- 0002 as part of the General Plan Amendments for Cycle 3 for calendar year 2025 to amend the City’s General Plan to update the Wildfire Hazard Severity Zones Map set forth in Figure PS-11 of the Public Safety Element to be consistent with the fire hazard severity zones map issued by the Office of the State Fire Marshal and adopted by the City Council (“General Plan Amendment”); and
WHEREAS, the Planning Commission based its recommendation to adopt the General Plan Amendment on the findings set forth below and a determination that there is no possibility that the Amendment will have a significant effect on the environment and, thus, is exempt from the requirements of the California Environmental Quality Act (“CEQA”); and WHEREAS, on November 5, 2025, the City Council held a duly noticed public hearing at which all persons wishing to testify in connection with the General Plan Amendment were heard and the General Plan Amendment was comprehensively reviewed.
NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF
THE CITY OF CORONA, CALIFORNIA, AS FOLLOWS:
SECTION 1. CEQA Findings. As the decision-making body for this General Plan Amendment, the City Council has reviewed and considered the information contained in the preliminary exemption assessment and the administrative records for this General Plan Amendment, including all written and oral evidence. Based upon the facts and information contained in the administrative record, including all written and oral evidence presented to the City Council, the City Council finds this action exempt pursuant to Section 15061(b)(3) of the CEQA Guidelines, which states that a project is exempt from CEQA if the activity is covered by the
2 common sense exemption that CEQA applies only to projects that have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. This action merely replaces the existing wildfire hazard severity zones map in the Corona General Plan with the fire hazard severity zones map issued by the Office of the State Fire Marshal on March 24, 2025, and adopted by Ordinance No. 3418 of the Corona City Council on June 4, 2025. As such, there is no possibility that GPA2025-0002 will have a significant effect on the environment and no further environmental analysis is required.
SECTION 2. General Plan Amendment Findings for GPA2025-0002. Based on the entire administrative record before the City Council, including all written and oral evidence presented to the City Council, the City Council hereby makes and adopts the following findings:
A. The General Plan Amendment is in the public interest and would not be detrimental to public health, safety and welfare as it ensures the General Plan reflects the most current wildfire hazard data available from the Office of the State Fire Marshal. This amendment enhances public safety by improving the City of Corona’s ability to plan for, prevent, and respond to wildfire hazards, thereby protecting residents, property, and natural resources.
B. The General Plan Amendment is internally consistent with the elements of the General Plan, including the goals and policies stated therein, for the following reasons:
(i) This General Plan Amendment is consistent with the purpose of the Public Safety Element of the General Plan, which is to protect the health and safety of the residents, businesses, institutions and visitors as well as property and natural resources from hazards. By incorporating the most current fire hazard severity zones map issued by the Office of the State Fire Marshal, this General Plan Amendment enhances the City’s ability to plan for, prevent, and respond to wildfire hazards. This ensures that the General Plan continues to guide land use, development and emergency preparedness in a manner that promotes public safety and reduces the potential for loss or damage due to wildfire.
(ii) This General Plan Amendment is consistent with General Plan Policy PS-8.9 to “continue to monitor and adhere to the latest changes in state legislation and guidelines with respect to fire planning, prevention, and suppression.” The updated fire hazard severity zones map was issued by the Office of the State Fire Marshal in 2025 pursuant to Government Code Section 51179 and reflects the most current scientific data regarding wildfire risk. By incorporating the updated map into Figure PS-11 of the Public Safety Element, this General Plan Amendment will ensure that the General Plan remains aligned with current state legislation and guidance, thereby supporting proactive fire planning, prevention, and suppression efforts.
SECTION 3. Approval of General Plan Amendment GPA2025-0002. The General Plan Amendment (GPA2025-0002) is hereby approved as part of the General Plan Amendments for Cycle 3 of calendar year 2025. The Wildfire Hazard Severity Zones Map as set
3 forth in Figure PS-11 in the Public Safety Element of the General Plan shall be amended as shown in Exhibit “A” attached hereto and incorporated herein by reference.
SECTION 4. Custodian of Records. The documents and materials that constitute the record of proceedings on which the findings set forth in this Resolution have been based are located at City of Corona City Hall, 400 S. Vicentia Avenue, Corona, California 92882. The custodian for these records is Joanne Coletta, Planning and Development Director.
SECTION 5. This Resolution shall take effect immediately upon its adoption.
PASSED, APPROVED AND ADOPTED this 5th day of November, 2025.

TO: Honorable Chair and Commissioners
FROM: Planning and Development Department
2025-408
APPLICATION REQUEST:
GPA2025-0002: General Plan Amendment to update the Wildfire Hazard Severity Zone map in the Public Safety Element to be consistent with the fire hazard severity zones map issued by the Office of the State Fire Marshal. (Applicant: City of Corona Fire Department) RECOMMENDED ACTION:
That the Planning and Housing Commission recommend APPROVAL of GPA2025-0002 to the City Council based on the findings contained in the staff report, find the project exempt from the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15061(b)(3), and adopt Resolution No. 2674 granting GPA2025-0002 as part of Cycle 3 of General Plan Amendments for 2025.
BACKGROUND
The Office of the State Fire Marshal (OSFM) of the California Department of Forestry and Fire Protection (CAL FIRE) is responsible for identifying Fire Hazard Severity Zones (FHSZ) throughout California. These zones are categorized as Moderate, High, or Very High based on consistent statewide criteria and the expected fire hazard levels in those areas, as required by Government Code 51178. The different severity zones are based on fuel loading, slope, fire weather, and other relevant factors including areas where winds have been identified by the OSFM as a major cause of wildfire spread.
Local Implementation
Chapter 15.16 of the Corona Municipal Code (CMC) governs the City’s regulations for FHSZs.
This chapter was first adopted in 2010 in accordance with the requirements established by Assembly Bill 337, which was enacted by 1992.
On March 24, 2025, the OSFM released an updated FHSZ map for the City of Corona (Exhibit 2). This map identifies the Local Responsibility Areas (LRAs) within Corona – areas for which the City is primarily responsible for providing wildfire protection. The LRAs are divided into three categories: Moderate, High, or Very High. According to CAL FIRE, the updated map incorporates new scientific data, including member spread patterns and localized climate information, providing a more accurate representation of the areas within the City that are susceptible to wildfire. In addition, the updated map includes designations for Moderate and High zones within the City whereas the previous version only included the designation for Very High.
Government Code Section 51179 requires local jurisdictions such as the City of Corona to designate, by ordinance, the moderate, high, and very high fire hazard severity zones within 120 days of receiving the updated FHSZ map from the OSFM. On May 14, 2025, the Corona Fire Department held a community meeting on the updated FHSZ map for the city. On June 4, 2025, the City Council adopted Ordinance No. 3418, amending Chapter 15.16 of the CMC to adopt the updated FHSZ map issued by the OSFM. The updated map went into effect July 4, 2025. The ordinance is attached as Exhibit 3.
General Plan
The City’s 2020-2040 General Plan was adopted by the City Council on June 3, 2020. The General Plan includes a Public Safety Element, which contains the FHSZ map under Figure PS-11. The version currently in the General Plan was in effect at the time of the General Plan’s adoption and must be updated to reflect the version recently issued by the OSFM and adopted by the City Council.
PROPOSED AMENDMENT
GPA2025-0002 is an amendment to the General Plan to update the Wildfire Hazard Severity Zones map (Figure PS-11 of the General Plan) in the Public Safety Element. Exhibit 4 shows the existing map, and Exhibit 5 shows the updated map that will replace the existing map.
The updated map identifies the Moderate (yellow), High (orange), and Very High (red) fire hazard zones within the City’s boundaries, as well as areas outside the boundaries located within the City’s Sphere of Influence (SOI) areas, which include Coronita, Home Gardens, El Cerrito, Temescal Valley, Eagle Valley, and a few other smaller pockets of unincorporated land.
In addition, the updated map distinguishes among the different agencies that have primary responsibility for wildfire protection:
• Local Responsibility Areas – Local Agency (City of Corona) • State Responsibility Areas – State of California
• Federal Responsibility Areas – Federal Government
ENVIRONMENTAL ANALYSIS
This General Plan Amendment is exempted from the California Environmental Quality Act (CEQA) pursuant to Section 15061(b)(3) of the CEQA Guidelines, the “common sense” exemption. This exemption applies where it can be seen with certainty that there is no possibility the activity may have a significant effect on the environment. The proposed General Plan Amendment (GPA2025-0002) qualifies, as it merely replaces the existing fire hazard severity zones map (Figure PS-11 of the Corona General Plan) with the updated map issued by the Office of the State Fire Marshal on March 24, 2025, and adopted by the Corona City Council on June 4, 2025.
FISCAL IMPACT
Approval of this General Plan Amendment will not have a financial impact.
PUBLIC NOTICE AND COMMENTS
A 10-day public notice was advertised in the Sentinel Weekly News as required by California Government Code Section 65353. No public outreach in addition to the outreach that was done before the adoption of Ordinance 3418 is required. As of the preparation of this report, the Planning and Development Department has not received any correspondence from the public in response to the General Plan Amendment.
STAFF ANALYSIS
To ensure consistency between local regulations (Chapter 15.16 of the CMC) and the City’s long-range planning documents, GPA2025-0002 updates Figure PS-11 in the Public Safety Element of the General Plan to incorporate the newly adopted FHSZ map. This amendment maintains alignment with state law, ensures the General Plan reflects the most current hazard mapping, and provides Corona Fire personnel as well as the community with clear and updated information on wildfire hazard areas. Therefore, this General Plan Amendment is recommended for approval by the Planning and Housing Commission.
FINDINGS FOR THE APPROVAL OF GPA2025-0002
1. GPA2025-0002 is exempted from the California Environmental Quality Act (CEQA) pursuant to Section 15061(b)(3) of the CEQA Guidelines, the “common sense” exemption. This exemption applies where it can be seen with certainty that there is
no possibility the activity may have a significant effect on the environment. The proposed project (GPA2025-0002) qualifies, as it merely replaces the existing fire hazard severity zones map in the Corona General Plan with the updated map issued by the Office of the State Fire Marshal on March 24, 2025, and adopted by Ordinance 3418 of the Corona City Council on June 4, 2025.
2. GPA2025-0002 is in the public interest and would not be detrimental to public health, safety and welfare, as it ensures the General Plan reflects the most current wildfire hazard data available from the Office of the State Fire Marshal. This amendment enhances public safety by improving the City’s ability to plan for, prevent, and respond to wildfire hazards, thereby protecting residents, property, and natural resources.
3. GPA2025-0002 is internally consistent with the elements of the General Plan, including the goals and policies stated therein for the following reasons:
a. The amendment is consistent with the purpose of the Public Safety Element of the General Plan, which is to protect the health and safety of the residents, businesses, institutions and visitors as well as property and natural resources from hazards. By incorporating the most current FHSZ map from the Office of the State Fire Marshal, the updated map enhances the City’s ability to plan for, prevent, and respond to wildfire hazards. This ensures that the General Plan continues to guide land use, development and emergency preparedness in a manner that promotes public safety and reduces the potential for loss or damage due to wildfire.
b. The amendment to the FHSZ map in the General Plan is consistent with General Plan Policy PS-8.9 to “continue to monitor and adhere to the latest changes in state legislation and guidelines with respect to fire planning, prevention, and suppression.” The updated FHSZ map was issued by the Office of the State Fire Marshal in 2025 pursuant to Government Code Section 51179 and reflects the most current scientific data regarding wildfire risk. By incorporating the updated map into Figure PS-11 of the Public Safety Element, the City ensures that the General Plan remains aligned with current state legislation and guidance, thereby supporting proactive fire planning, prevention, and suppression efforts.

DATE: 11/05/2025
TO: Honorable Mayor and City Council Members
FROM: Planning and Development Department
2025-390
REQUEST FOR CITY COUNCIL ACTION
SUBJECT:
REQUEST BY COUNCIL MEMBER SPEAKE TO DISCUSS ESTABLISHING TIME
LIMITS FOR TEMPORARY FENCING AND BOARDED WINDOWS FOR UNOCCUPIED
DEVELOPED PROPERTIES
EXECUTIVE SUMMARY:
This staff report asks the City Council to provide direction on Council Member Speake’s request to explore an amendment to the Corona Municipal Code to set time limits on temporary fencing and materials used to board up windows on unoccupied developed properties. The future agenda item request was presented to the City Council at its meeting on March 19, 2025. The Council agreed to have further discussion on this request.
RECOMMENDED ACTION:
That the City Council provide direction on whether staff should explore an amendment to the Corona Municipal Code to set time limits for temporary fencing and boarded windows on unoccupied developed property.
BACKGROUND & HISTORY:
At the City Council meeting on March 19, 2025, Council Member Speake requested to explore options that could be amended into the city’s municipal code to limit the amount of time temporary fencing and boarded windows can be used on unoccupied developed properties. The grounds for this discussion were prompted by the unoccupied buildings located at the northeast corner of Main Street and Parkridge Avenue, and the Wells Fargo
building located at 1111 W. Sixth Street, which stayed vacant for several years with ongoing property maintenance violations before being demolished. Unlike the partially vacant commercial center at the corner of Main Street and Parkridge Avenue, the former Wells Fargo building located on Sixth Street was enclosed with temporary fencing before it was demolished.
Code Compliance and Police Department
The city’s Code Compliance division requires property owners of unoccupied properties to do the following to deter public nuisance and unlawful activity on the property:
Secure the property to deter transient activity, loitering, and illegal dumping (staff commonly recommend using temporary fencing).
Regular clean-up of the property from debris and graffiti. Replace or boardup broken windows and doors to prevent access to the building. Remove dead vegetation from landscaped areas.
The Corona Police Department also requests support to have windows boarded up on unoccupied buildings to prevent intrusion into the building. This is to minimize calls for service of unlawful activities inside the building and to deter squatters.
Corona Municipal Code Chapter 8.32, Property Maintenance All properties in the city, including vacant undeveloped properties and unoccupied developed properties, are subject to the property maintenance regulations established in Corona Municipal Code (CMC) Chapter 8.32,
Per CMC Section 8.32.030, unoccupied buildings are not considered a nuisance if:
The premises are locked and secured from intrusion by persons and animals, The windows are not broken or are boarded up by a method or material approved by the Planning and Development Department,
The property is actively maintained and monitored for the removal of trash, debris and graffiti,
The on-site landscaping and exterior building materials are maintained, The building continues to be in compliance with code regulations, and Criminal activity is prevented on the premises.
Permit Requirement
A building permit for temporary fencing is only required if the fencing uses in-ground footings. This type of fencing is typically only used to secure vacant, undeveloped properties to prevent illegal dumping and trespassing. No building permit is required for temporary fencing using panel stands not affixed to the ground or to board up windows on unoccupied buildings. As a result, most temporary fencing of buildings is not regulated by the CMC unless it pertains to property maintenance.
ANALYSIS:
Because temporary fencing is routinely used to keep vacant properties secure and help owners comply with property maintenance requirements, any amendment to the CMC
setting a time limit on temporary fencing and materials will need to address how owners can become compliant with requirements to secure and maintain the property.
Additionally, consideration should be given to the mechanism of enforcement for a time limit in the absence of a permit requirement for temporary fencing.
Staff have provide four key concerns (Table 1) for a proposed time limits on the methods of security, such as temporary fencing and boarded-up windows, on unoccupied developed properties.
TABLE 1
Time Limits on Temporary Fencing & Boarded Windows
Concerns and Issues
Concern Issue
Without the continuous use of reasonable
security measures, unoccupied properties
are exposed to activities that would create
nuisances.
Illegal dumping.
Homeless camps and increased
risk of structure fires.
Loitering.
Property damage.
Graffiti.
Intrusion into buildings.
Illegal activities inside breached
buildings.
Increase calls for service to Code
Compliance and the Police
Department.
Frequent contact with the property
owner to address violations.
Balancing enforcement with the property
owner.
Limiting reasonable security
measures is counterproductive to
Code Compliance’s enforcement in
requiring property to be secured to
deter nuisances and unlawful
activity.
No building permit is required for
temporary fencing using panel stands not
affixed to the ground and boards covering
windows.
Some type of permit would be
required to monitor imposed time
limits.
Determining how often a property
can use temporary fencing and
boarded windows to secure an
unoccupied building (one-time
permit vs. annual permit).
Market constraints or circumstances
associated with the property may not
result in the occupancy of the property
even if the methods of reasonable security
are limited.
The city does not control the leasing
of the building or the sale of
property.
If the Council directs staff to explore an amendment to the CMC, Table 2 lists the tasks and estimated time for staff to research other cities and propose options to the City Council for consideration.

FINANCIAL IMPACT:
Full-time city staff resources will be used to conduct research on this request, which is part of the department’s budgeted positions. No additional cost is anticipated with this request.
ENVIRONMENTAL ANALYSIS:
This action is exempt pursuant to Section 15061(b)(3) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt from the CEQA if the activity is covered by the commonsense exemption that CEQA applies only to projects that have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. This request is for staff to receive policy direction from the City Council and will not have a significant effect on the environment. Therefore, no environmental analysis is required.

Future Agenda Item Request Form
Future agenda items should be limited to new issues that emerge during the course of the year that are urgent and cannot wait until the next priority setting session of Council before requiring action.
Name: Wes Speake
Date: 3/12/2025
Title Name/Topic: Explore CMC ordinance changes to set time limits for specific for Temp fencing and boarded up windows
Background
1. What is the purpose for the request i.e. what you are trying to achieve or do? o At what point is temporary fencing not temporary?
o Can we set a time limit for temporary fencing? The municipal code allows temporary fencing for vacant lots, agricultural areas or similar uses for security purposes. It does not limit the amount of time the fencing can be up because it can be used for more than one purpose. For example, it is unknown when a vacant parcel may be developed, and the temporary fencing is used to deter illegal dumping on the property.
• Plan amendment or by zone? To impose a time limit, the municipal code would need to be amended.
o Can we set a time limit for boarded up windows? To impose a time limit, the municipal code would need to be amended.
• Plan amendment or by zone?
o Other communities don't have issues like this, what they doing that we aren't? Staff has not researched the extent of this issue in other cities. But I would venture to guess they do have issues like these.
o What can we do legally to address the appearance of properties? The city follows the regulations provided in the city’s Property Maintenance Ordinance, CMC Chapter 8.32. The ordinance does recognize vacant properties and the way they are to be maintained. Buildings or structures, including the premises on which it is located, that have been vacant for more than 90 days do not constitute a public nuisance if the property is being actively maintained and monitored. Active maintenance and monitoring include no unlocked or unsecured vacant buildings and are boarded up by a material or method approved by the Building Official, maintenance of the landscaping, maintenance of the exterior of the building, regular removal of trash, debris and graffiti, the building is in compliance with codes and regulations (structural compliance), and criminal activity is being prevented on the property.
2. What is the scope of the work you wish to see done?
Explore changes to prevent Parkridge and Main from reoccurring or Wells Fargo building build limbo
3. Does this request align with the City’s Strategic Plan? How? #5 Sense of Place
4. What is the desired timeline to have the issue considered by Council? Soon
5. Is the issue urgent requiring action before the next priority setting session of Council (Fall Workshop)?

REQUEST FOR CITY COUNCIL ACTION
SUBJECT:
HISTORIC CIVIC CENTER OPERATIONS PLAN UPDATE
EXECUTIVE SUMMARY:
This staff report requests that the City Council provide direction on optimizing the Historic Civic Center. The City of Corona’s Strategic Plan includes a strategy under the goal Sense of Place to “Designate the Historic Civic Center as Corona’s center for the arts and relocate all non-arts lessees.” The Historic Civic Center Operations Plan provides a roadmap to help implement this strategy, including concepts and options for future programming and optimization of the Historic Civic Center.
RECOMMENDED ACTION:
That the City Council provide direction on the optimization of the Historic Civic Center.
BACKGROUND & HISTORY:
The Historic Civic Center (HCC) was constructed in 1923 and served as Corona’s second high school until 1962, when it became Corona City Hall. In 2005, a new City Hall was built, and the Historic Civic Center was re-purposed to host mixed-use programs and leases with local non-profits, arts organizations, and service providers. This same year, the HCC was added to the National Register of Historic Places, the official list of the nation’s historic places worthy of preservation.
The HCC campus comprises the main building and three auxiliary buildings, which offer a range of community programming. The main building includes multiple classrooms and suites, a community room, and a 383-seat theater. The auxiliary buildings include the East Annex, which is currently leased for arts and theater programming; the historic gymnasium, used for city sports programming; and the Vicentia Activity Center, used for afterschool programming.
In 2021, the City Council adopted the City of Corona Strategic Plan that includes strategies under the goal Sense of Place to 1) Renovate the Historic Civic Center to become the City’s premier performing and visual arts center, and 2) Designate the Historic Civic Center as Corona’s center for the arts and relocate all non-arts lessees.
On April 16, 2025, staff presented the draft HCC Operations Plan to the City Council, outlining proposed programming improvements, facility repairs and maintenance, and an implementation plan. During the meeting, the City Council directed staff to proceed with plans to improve the HCC building and campus, and to work with the HCC arts partners on integrating them into the operations plan.
ANALYSIS:
From May – October 2025, staff met individually with each of the HCC arts partners to collect feedback about their programming and site needs. The key takeaways from these meetings are: 1) all arts partners like their current set up and lease arrangement at the HCC, and no change is desired; 2) most arts partners expressed openness to sharing space under certain conditions; and 3) several suggestions were offered for improvements to the building and suites.
Based on the feedback received from the arts partners, staff has prepared three options for the City Council to consider regarding the future optimization of the Historic Civic Center.
Option 1 – Minimal Change
Relocate all non-arts tenants
Complete renovations on vacant suites
Transition city-run arts programs to vacant suites
Defer improvements on arts tenants’ suites until facility optimization can occur Option 2 – Phase-In Facility Optimization
Same as Option 1, AND:
Evaluate demand for city-run programs
Phase in facility optimization based on city program expansion needs and the needs of other tenants
Improve remaining suites as space becomes available and/or existing tenants can accommodate renovations within program schedules
Option 3 – Full Facility Optimization
Same as Option 1, BUT:
Conduct improvements on the full building and campus
Transition city-run arts programs to HCC and expand programming Fully implement facility optimizations to maximize arts programming and HCC usage
Staff is seeking direction from the City Council on their desired facility optimization for the HCC based on the options listed above.
FINANCIAL IMPACT:
There is no financial impact associated with the City Council’s review and feedback of the HCC Operations Plan. The maintenance and repairs identified for the HCC site and building are preliminary estimates, and a formal assessment and scope of work are needed to determine the final cost of all improvements. Individual projects and contracts for site and building improvements will be brought to City Council, as needed, for final review and approval.
ENVIRONMENTAL ANALYSIS:
This action is exempt pursuant to Section 15061(b)(3) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt from CEQA if the activity is covered by the commonsense exemption that CEQA applies only to projects that have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. This action seeks feedback on an operations plan for the Historic Civic Center. Therefore, no environmental analysis is required.

2 Facility Optimization
Phase-In Facility Optimization
• Same as Option 1, AND:
• Evaluate demand for City-run
programs.
• Phase in facility optimization based
on City program expansion needs
and needs of other tenants
• Improve remaining suites as space
becomes available and/or existing
tenants can accommodate
renovations within program
schedules
3 Facility Optimization
Full Facility Optimization
• Same as Option 1, BUT:
• Conduct improvements on the full
building and campus
• Transition city-run arts programs to
HCC and expand programming
• Fully implement facility optimizations
to maximize arts programming and
HCC usage
Proposed Plan
31 • Update all suites
o Layouts, flooring, paint, ceilings,
lighting, acoustics, sinks,
storage, and A/V
• Expand city arts programming now
to maximize facility usage
• Reposition some arts tenants to
group them into new spaces based
on program type
• Share some spaces as program
schedules allow to maximize space
use

• Share space when CAT programs are not
operating (i.e., weekday mornings, Sundays)
Corona Art Association (CAA) • Move to the 2nd floor into the new Fine Arts area • Display and sell art in Art Gallery • Share space when CAA programs are not operating (i.e., weekday mornings and early afternoons)
Arts Tenant Impacts
33 Corona Symphony Orchestra &
Conservatory • Keep all classes in the current location • Maintain rehearsal space in Community Room or new Rehearsal / Black Box Area
• Share space with YMCA and other music
programs when Corona Symphony is not
operating (Mon, Tues, Thurs, Fri, and Sat)
YMCA Music Program • Relocate music classes to 1st floor Music Studio • Relocate recording studio to 2nd floor Music Studio
• Share space with Corona Symphony and other
music programs when YMCA music is not
operating (Weds & Sat)
• The HCC could accommodate as many as 40 distinct
daily activities.
• Programming would be dependent on demand: resident
interests, market trends, and availability of instructors (internal, contract, partner).
• Morning use would consist of tiny tots, active
adults/seniors, and adaptive groups.
• Afternoon use would include school-age and teens.
• Evening use would cater to working adults and families. • Comparison cities indicate higher usage Mondays –
Thursdays, with less usage on Fridays and Saturdays.
• Most facilities closed on Sundays, apart from theater productions and reservations for private events.

REQUEST FOR CITY COUNCIL ACTION
SUBJECT:
ORDINANCE AMENDING VARIOUS CHAPTERS WITHIN TITLE 15 OF THE CORONA MUNICIPAL CODE AND ADOPTING BY REFERENCE THE 2025 CALIFORNIA BUILDING STANDARDS CODE (CALIFORNIA CODE OF REGULATIONS, TITLE 24) EXECUTIVE SUMMARY:
This staff report asks the City Council to approve Ordinance No. 3421, which amends various chapters within Title 15 of the Corona Municipal Code (CMC) and adopt by reference the 2025 California Building Standards Code (California Code of Regulations, Title 24). Title 15 of the CMC includes the California Building Standards Code, as well as local amendments related to building construction that are necessary due to local climatic, geological or topographical conditions. The California Building Standards Commission recently adopted new model codes with amendments, and the 2025 California Building Standards Code will become effective throughout the State on January 1, 2026.
RECOMMENDED ACTION:
That the City Council introduce by title only and waive full reading for consideration of Ordinance No. 3421, first reading of an ordinance amending Chapters 15.02, 15.04,
15.05, 15.07, 15.08, 15.09, 15.10, 15.11, 15.12, 15.20, 15.28, and adding Chapter 15.25 to Title 15 of the Corona Municipal Code, adopting by reference the 2025 Edition of the California Building Standards Code (California Code of Regulations, Title 24); including the 2025 California Building Code; the 2025 California Green Building Standards Code; the 2025 California Residential Code; the 2025 California Mechanical Code; the 2025 California Energy Code; the 2025 California Historical Building Code; the 2025 California
Existing Building Code; the 2025 California Fire Code; the 2025 California Plumbing Code; the 2025 California Wildland-Urban Interface Code; and the 2025 California Electrical Code; together with certain additions, insertions, deletions and changes thereto.
BACKGROUND & HISTORY:
The California Building Standards Code, Title 24, is the established minimum regulation for the design and construction of buildings and structures in California. The California Building Standards Code is published in its entirety every three years by order of the California Legislature. The California Building Standards Commission recently adopted new model codes with amendments, and the 2025 California Building Standards Code will become effective throughout the State on January 1, 2026.
State law mandates that local governments enforce the regulations of the California Building Standards Code and amend local ordinances for conformity. The City of Corona adopts by reference the Building Standards Code within Title 15 of the Corona Municipal Code (CMC), covering the Building Code, Residential Code, Fire Code, Plumbing Code, California Wildland Urban Interface Code, Mechanical Code, Electrical Code, Historical Building Code, Existing Building Code, Energy Code, and Green Building Standards Code. The ordinance also contains certain local amendments that are considered reasonably necessary because of local climatic, geological, or topographical conditions.
ANALYSIS:
The California Building Standards Code (CBSC) is based on the latest model codes published by the International Code Council (ICC), National Fire Protection Association (NFPA), and the International Association of Plumbing and Mechanical Officials (IAPMO).
These nationally recognized model codes go through a lengthy code development process, and when new versions are published, the California Building Standards Commission uses these updated codes to amend the CBSC.
The 2025 CBSC contains changes such as errata to correct errors or typos, revised wording clarification, and more significant changes to reflect increases in building system performance, California's renewable energy goals, and the latest building technology and innovation. The most noteworthy of these changes in the new CBSC include:
• A new California Wildland-Urban Interface Code has been added to the CBSC to establish minimum requirements for land use and the built environment in designated wildland-urban interface areas into a single code. • Electric heat pump water heaters and central space heaters are now required for most new construction instead of fuel-burning heaters. • Increased minimum sizing of solar and battery energy storage systems for new construction.
• Where fuel burning water heaters are allowed to be installed in new residential structures, the residential structure must be “heat pump ready”. This means the
residential structure is equipped to easily convert appliances from fuel-burning to electric.
• Increased electric vehicle charging requirements for multifamily buildings.
The amendments to Title 15 of the CMC are based on the 2025 CBSC update, and include updates to existing ordinances for uniformity with the new codes, modern construction methods. Noteworthy changes to the Fire Code and the new Wildland Urban Interface Code in Title 15 of CMC include the following.
Chapter 15.12, Fire Code
Section 15.12.330 is added to CMC Chapter 15.12 to require a fallout radius for firework displays to be 100 ft/in (22 m/25 mm) of the internal mortar diameter of the largest aerial shell to be fired, unless otherwise approved by the Fire Chief. An exception to this requirement can include having a fully staffed fire engine present at the location of the fireworks display.
Chapter 15.25, Wildland Urban Interface Code
Chapter 15.25 is a new chapter added to the CMC and covers fire flow requirements for properties located in Very High Fire Severity (VHFS) Zones. Section 15.25.130 of this chapter will require subdivisions consisting of five or more lots for one- and two-family dwellings located in the VHFS Zones to have a fire flow of 2,000 gallons per minute (GPM) compared to the 1,500 gpm required in non-VHFS Zones. Additionally, the fire flow will increase to 2,500 gpm for a dwelling unit exceeding 3,600 square feet of floor area. The fire flow requirement of this section can be reduced to 1,500 gpm if the entire subdivision is constructed in compliance with the most current version of the Insurance Institute for Business and Home Safety (IBHS) Wildfire Prepared Neighborhood Technical Standard.
The public hearing on the proposed amendments to Title 15 of the CMC and the adoption of the ordinance is scheduled for the City Council meeting on November 19, 2025, which is required after the first reading of the ordinance.
FINANCIAL IMPACT:
The adoption of this ordinance will have no financial impact.
PUBLIC NOTICE:
Per Government Code Section 6066 the public notice for the public hearing on the adoption of the ordinance shall be published once a week for two successive weeks, and at least 14 days before the public hearing, with at least five days intervening between the two publication dates. The first notice was published on October 31, 2025, in the Sentinel, with the second notice scheduled to be published on November 7, 2025, before the public hearing date on November 19, 2025.
ENVIRONMENTAL ANALYSIS:
The Ordinance does not qualify as a project under State CEQA Guidelines, Section 15378(a) because it has no potential to result in either a direct, or reasonably foreseeable
indirect, physical change in the environment. It can also be seen with certainty that there is no possibility that the proposed Ordinance may have a significant effect on the environment because the Ordinance simply updates existing building codes in compliance with the California Building Standards Code; and the adoption of the Ordinance will not result in any development or any new activity with the potential to impact the environment. Therefore, no environmental analysis is required.

WHEREAS, Government Code Section 50022, et seq. and California Health & Safety Code Section 17922 empower the City of Corona ("City") to adopt by reference the California Building Standards Code as provided in Title 24 of the California Code of Regulations; and
WHEREAS, in December of 2022 the City Council of the City of Corona adopted the 2022 California Building Standards Code with certain local amendments; and WHEREAS, the California Building Standards Commission ("Commission") recently adopted new amendments to the California Building Standards Code; and WHEREAS, California Health & Safety Code, Sections 17958.5 and 18941.5 authorize cities and counties to modify the California Building Standards Code by adopting more restrictive standards and modifications if such standards and modifications are accompanied by express findings that they are reasonably necessary because of local climatic, geological or topographical conditions; and
-2-
JAMIER\05100.16000\10315457.9
WHEREAS, the City Council of the City of Corona ("City Council") finds that these local climatic, geological or topographical conditions include, but are not limited to, the following:
1. The City is subject to relatively low amounts of precipitation, very low humidity levels and extremely high temperatures. These climatic conditions are conducive to the spread of drought conditions and fires. For example, during July, August and September, temperatures often exceed 100 degrees Fahrenheit. During the same months, humidity is usually less than 40% and measurements of less than 10% are not uncommon. These recordings have been documented by the Riverside County Flood Control District and the National Climatic Data Center.
2. The City is subject to extremely strong winds, commonly referred to as "Santa Ana Winds," which can reach speeds of up to 95 miles per hour. In addition, the convergence of the marine shore air flow and the desert air flow create steady winds on a daily basis. Finally, the City is bordered on the south by steep, rugged, brush-covered mountains and parts of the City contain hilly terrain and mounds, which either contribute to or create gusty wind conditions by causing a natural funneling effect and increasing wind speeds over the City.
3. The City is also subject to moderately strong shaking and surface ruptures from seismic activity in the area. The geologic and seismic setting of the City is dominated by the Chino and Elsinore earthquake faults along the southwest portion of the City and a diversity of bedrock and alluvial soils that may significantly affect the intensity of earthquake shaking. The Elsinore fault is located a short distance southwest of the City, while the Chino fault, which is subparallel to the Elsinore fault, is located just inside the City’s southwestern boundary. Of the two faults, the Chino fault has the greater potential for surface rupture leading to structural damage of structures in the City. Moreover, the thin alluvial soils found in parts of the City contribute to a moderately high potential for liquefaction in certain areas.
WHEREAS, the aforementioned geologic and climatic conditions have also contributed to the loss or damage of thousands of homes and commercial properties in California over the last several decades. The top 20 fires in the State have consumed over 46,000 structures, and there have been hundreds more fires with thousands more structures destroyed. The 30,305- acre Freeway Complex Fire from November 2008 burned 318 structures, including several in Corona; the 2662-acre Canyon Fire from September 2017 threatened 2715 homes in Corona, before being contained; and the 23,136-acre Holy Fire from August 2018 nearly threatened 2638 homes in Corona; and
WHEREAS, these fires, as well as the Whittier Earthquake of 1987 and Northridge Earthquake of 1994, have resulted in the tragic loss of lives along with enormous property losses; and
WHEREAS, based upon the recommendations of the Building Official and Fire Chief, the City Council finds that the proposed amendments to the 2025 California Building Standards Code ("amendments") are more restrictive than the standards adopted by the Commission, would decrease the potential incidence of property damage, injury and death due to
-3-
JAMIER\05100.16000\10315457.9
fires and earthquakes, and are reasonable and necessary to mitigate the aforementioned local climatic, geologic or topographical conditions; and
1. The amendments to section 101.4 of Chapter 1 Division II of the 2025 California Building Standards Code, as set forth in Section 2 of this ordinance, ensure that structures and related devices and equipment required by other referenced codes are maintained in a manner that would prevent danger to emergency responders or users thereof arising from conditions related to an emergency incident caused by high winds, fires, or seismic activity.
2. The amendments to Sections 105.1 of Chapter 1 Division II of the 2025 California Building Code, as set forth in Section 2 of this Ordinance, ensure that structures such as fences, retaining walls and signs, that may become potentially dangerous structures in an earthquake or high winds, are constructed in accordance with applicable codes, ordinances and standards; and
3. The amendment to Section 105.6 of Chapter 1 Division II of the 2025 California Building Code, as set forth in Section 2 of this Ordinance, preserves public health, safety and welfare by limiting construction noise and mitigating the effects of having portions of the City’s residential areas constructed on hilly terrain. Many times it is not possible to construct noise barriers between noise sources and noise receptors in hilly areas. Under such circumstances, the "line of sight" between the noise source and the receiver cannot be adequately impeded by other structures such as fences and walls because such structures cannot be constructed on certain lots due to the grade differential between lots; and
4. The addition of Section 105.8 to Chapter 1 Division II of the 2025 California Building Code, as set forth in Section 2 of this Ordinance, is needed to assure that each permit is applicable to the location and conditions for which it was originally obtained; and
5. The amendments to Section 110.3.3.1 and 110.3.6.1 of the 2025 California Building Code, as set forth in Section 3 of this Ordinance, adding additional required inspections, including a sub-frame inspection, a roof sheathing and shear inspection and a plaster inspection assure that all construction and use of buildings conforms to the requirements of the California Building Standards Code in so that maximum protection from the wind, fire and earthquake conditions is provided; and
6. The addition of Section 3109.1.1 to the 2025 California Building Code, as set forth in Section 3 of this Ordinance, isrequired to ensure pool safety and decrease the likelihood of injuries and death due to unauthorized use of pools and the greater use of outdoor swimming pools due to climatic conditions; and
7. The addition of Section 1505.1.3 to the 2025 California Building Code as set forth in Section 3 of this Ordinance and the additions of section R902.1.3 to the 2025 Residential Code as set forth in Section 5 of this Ordinance requires Class "A" roofing which is effective against severe fire exposure, is not readily flammable, affords a fairly high degree of fire protection to roof decks, does not slip from position, and poses no flying-brand hazard, and is
-4-
JAMIER\05100.16000\10315457.9
therefore more fire resistant than other classes of roofing not possessing these characteristics that are adopted for use by the Commission; and
8. The amendments to the 2025 California Fire Code, as set forth in Section 10 of this Ordinance, including the amendments adding definitions to Section 202; the amendment to Section 112.4.2 imposing additional costs against persons responsible for violations of the code; the amendments to Sections 304.1.2, 305.6, 307.6, 307.7, 308.1.6.3, 324, 325, 326, 327, 503.2.1, 503.2.4, 503.7, 505.1, 507.5.1, 507.5.5 507.5.7, 4907.3, 4911 imposing additional requirements for maintenance, clearance and management of vegetation and fuel modification areas, outdoor fires, premises identification, fire access roads, turning radii, clearance around hydrants and other fire apparatus; and amendments to the 2025 California Building Code, as set forth in Section 3 of this Ordinance; and the amendments to the 2025 California Wildland-Urban Interface Code, as set forth in Section 12 of this Ordinance, are needed to minimize the risk of fire which is increased by the climatic, geological and dry brush conditions in the City of Corona, described above in this Ordinance, and to mitigate the spread of fire especially during high wind conditions described above in this Ordinance; and
9. The addition of Section 710 to the 2025 California Fire Code, requiring onehour fire construction for all eaves, as set forth in Section 10 of this Ordinance, is reasonably necessary to mitigate the potential for the spread of fires from flying brands, ashes and sparks during high wind conditions and mitigate potential property damage, injury and death; and
10. The amendment to Section 314.3 of the 2025 California Plumbing Code, as set forth in Section 11 of this Ordinance, prohibiting unattended excavations without appropriate barricades is needed to assure that excavations for sewer or sewage disposal facilities do not create a hazard for persons, especially during periods of wind, rain or surface movements caused by earthquakes; and
WHEREAS, the Fire Marshal and Building Official have also recommended that changes and modifications be made to the California Building Standards Code, which are necessary for administrative clarification and to establish administrative standards for the effective enforcement of the building standards of the City of Corona, or are reasonably necessary to safeguard life and property within the City and do not modify a building standard pursuant to California Health & Safety Code Section 17958, 17958.7, and/or 18941.5, which amendments consist of:
1. Amendments to Chapter 1 Division II, Sections 501.2, 904.3.5, Chapter 35 and Appendix H of the 2025 California Building Code; and
2. Amendments to Sections 103.2, 104.2, 105.5, 112.4, 112.4.2, 202, 324, 507.5.1, 507.5.5, 510.1, 510.4.1.3, 903.3.5.3, 904.3.5, 1201.1.1, 4907.3, 5001.5.2, 5608.2, Chapter 80, and Appendix B and Appendix C of the 2022 California Fire Code; and WHEREAS, the City Council finds that the local amendments to the 2025 California Building Standards Code, codified in Title 24 of the California Code of Regulations (“Code”) described herein are supported by the local climatic, geologic and/or topographic
-5-
JAMIER\05100.16000\10315457.9
conditions described herein, and further finds that the remainder of the said changes and modifications are of an administrative or procedural nature, or concern themselves with subjects not covered by the Code, or are reasonably necessary to safeguard life and property within the City of Corona; and
WHEREAS, Assembly Bill 130 (2025) (“AB 130”), among other things, amended Health and Safety Code Section 17958 to prohibit, between October 1, 2025, and June 1, 2031, modifications to the provisions of the California Building Standards Code affecting residential units unless certain conditions exist, including: (a) the modifications are substantially equivalent to modifications made prior to September 30, 2025; (b) the modifications are related to home hardening; or (c) the modifications are related to administrative practices that result in the establishment, alteration, or removal of local programs related to enforcement of building code violations or complaints alleging building code violations; and WHEREAS, as set forth in Informational Bulletin 25-03 issued on September 22, 2025, the Commission has concluded that modifications to the California Building Standards Code are substantially equivalent to modifications made prior to September 30, 2025 if it is a local amendment applicable to residential units that is being carried forward from a previously filed ordinance (i.e., an ordinance amending the 2022 California Building Standards Code) with no material change in regulatory effect to the existing standards; and WHEREAS, the Commission also concluded as part of Informational Bulletin 25- 03 that the term “home hardening” means local amendments to the California Wildland-Urban Interface Code (Part 7 of Title 24); and
WHEREAS, the local amendments to the 2025 California Building Standards Code that are incorporated into this Ordinance are either substantially equivalent to existing regulations adopted by the City as part of the 2022 California Building Standards Code, which were in effect as of September 30, 2025, or the changes relate to home hardening and are adopted in connection with the California Wildland-Urban Interface Code, or are related to administrative practices that result in the establishment, alteration, or removal of local programs related to enforcement of building code violations or complaints alleging building code violations; and WHEREAS, any and all other legal prerequisites relating to the adoption of this Ordinance have occurred.
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF CORONA
DOES ORDAIN AS FOLLOWS:
SECTION 1. The City Council hereby adopts the recitals contained in this ordinance as findings to support the modifications to the 2025 California Building Standards Code made herein.
SECTION 2. Chapter 15.02 of the Corona Municipal Code is hereby amended to read as follows:

SECTION 14. Prior Ordinances Repealed. Upon the effective date of this Ordinance, all former ordinances or parts thereof conflicting or inconsistent with the provisions of this Ordinance or the codes herein adopted by reference and any other ordinance in conflict herewith are hereby repealed and declared to be of no further force and effect.
SECTION 15. CEQA. The City Council finds that the adoption of the California Building Standards Code and the amendments proposed herein are exempt pursuant to Section 15061(b)(3) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt from CEQA if the activity is covered by the common sense rule that CEQA applies only to projects that have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. This Ordinance, which adopts updated building and safety standards, is enacted to mitigate the threats posed to public peace, health and safety from earthquakes, storms, flooding, high winds and fire. The Ordinance also does not qualify as a project under State CEQA Guidelines, section 15378(a)) because it has no potential to result in either a direct, or reasonably foreseeable indirect, physical change in the environment. It can also be seen with certainty that there is no possibility that the proposed Ordinance may have a significant effect on the environment because the Ordinance simply updates existing building codes in compliance with the California Building Standards Code; and the adoption of the Ordinance will not result in any development or any new activity with the potential to impact the environment. Therefore, no further environmental analysis is required. Staff is directed to file a notice of exemption within five (5) days of the adoption of this Ordinance.
SECTION 16. Severability. If any section, subsection, subdivision, paragraph, sentence, clause or phrase added by this Ordinance, or any part thereof, is for any reason held to be unconstitutional or invalid or ineffective by any court of competent jurisdiction, such decision shall not affect the validity or effectiveness of the remaining portions of this Ordinance or any part thereof. The City Council hereby declares that it would have passed each section, subsection, subdivision, paragraph, sentence, clause or phrase thereof irrespective of the fact that any one or more subsections, subdivisions, paragraphs, sentences, clauses or phrases are declared unconstitutional, invalid or ineffective.
SECTION 17. Certification/Publication. The Mayor shall sign this ordinance and the City Clerk shall attest thereto and shall within fifteen days of its adoption cause it or a summary of it to be published in the Press Enterprise, a newspaper published and circulated in the City of Corona; and thereupon and thereafter this ordinance shall take effect and be in force according to law.

THERETO
WHEREAS, Government Code Section 50022, et seq. and California Health & Safety Code Section 17922 empower the City of Corona ("City") to adopt by reference the California Building Standards Code as provided in Title 24 of the California Code of Regulations; and
WHEREAS, in December of 2022 the City Council of the City of Corona adopted the 2022 California Building Standards Code with certain local amendments; and WHEREAS, the California Building Standards Commission ("Commission") recently adopted new amendments to the California Building Standards Code; and WHEREAS, California Health & Safety Code, Sections 17958.5 and 18941.5 authorize cities and counties to modify the California Building Standards Code by adopting more restrictive standards and modifications if such standards and modifications are accompanied by express findings that they are reasonably necessary because of local climatic, geological or topographical conditions; and
-2-
JAMIER\05100.16000\10315457.8 JAMIER\05100.16000\10315457.8 WHEREAS, the City Council of the City of Corona ("City Council") finds that these local climatic, geological or topographical conditions include, but are not limited to, the following:
1. The City is subject to relatively low amounts of precipitation, very low humidity levels and extremely high temperatures. These climatic conditions are conducive to the spread of drought conditions and fires. For example, during July, August and September, temperatures often exceed 100 degrees Fahrenheit. During the same months, humidity is usually less than 40% and measurements of less than 10% are not uncommon. These recordings have been documented by the Riverside County Flood Control District and the National Climatic Data Center.
2. The City is subject to extremely strong winds, commonly referred to as "Santa Ana Winds," which can reach speeds of up to 95 miles per hour. In addition, the convergence of the marine shore air flow and the desert air flow create steady winds on a daily basis. Finally, the City is bordered on the south by steep, rugged, brush-covered mountains and parts of the City contain hilly terrain and mounds, which either contribute to or create gusty wind conditions by causing a natural funneling effect and increasing wind speeds over the City.
3. The City is also subject to moderately strong shaking and surface ruptures from seismic activity in the area. The geologic and seismic setting of the City is dominated by the Chino and Elsinore earthquake faults along the southwest portion of the City and a diversity of bedrock and alluvial soils that may significantly affect the intensity of earthquake shaking. The Elsinore fault is located a short distance southwest of the City, while the Chino fault, which is subparallel to the Elsinore fault, is located just inside the City’s southwestern boundary. Of the two faults, the Chino fault has the greater potential for surface rupture leading to structural damage of structures in the City. Moreover, the thin alluvial soils found in parts of the City contribute to a moderately high potential for liquefaction in certain areas.
WHEREAS, the aforementioned geologic and climatic conditions have also contributed to the loss or damage of thousands of homes and commercial properties in California over the last several decades. The top 20 fires in the State have consumed over 46,000 structures, and there have been hundreds more fires with thousands more structures destroyed. The 30,305- acre Freeway Complex Fire from November 2008 burned 318 structures, including several in Corona; the 2662-acre Canyon Fire from September 2017 threatened 2715 homes in Corona, before being contained; and the 23,136-acre Holy Fire from August 2018 nearly threatened 2638 homes in Corona; and
WHEREAS, these fires, as well as the Whittier Earthquake of 1987 and Northridge Earthquake of 1994, have resulted in the tragic loss of lives along with enormous property losses; and
WHEREAS, based upon the recommendations of the Building Official and Fire Chief, the City Council finds that the proposed amendments to the 2025 California Building Standards Code ("amendments") are more restrictive than the standards adopted by the Commission, would decrease the potential incidence of property damage, injury and death due to
-3-
JAMIER\05100.16000\10315457.8 JAMIER\05100.16000\10315457.8 fires and earthquakes, and are reasonable and necessary to mitigate the aforementioned local climatic, geologic or topographical conditions; and
1. The amendments to section 101.4 of Chapter 1 Division II of the 2025 California Building Standards Code, as set forth in Section 2 of this ordinance, ensure that structures and related devices and equipment required by other referenced codes are maintained in a manner that would prevent danger to emergency responders or users thereof arising from conditions related to an emergency incident caused by high winds, fires, or seismic activity.
2. The amendments to Sections 105.1 of Chapter 1 Division II of the 2025 California Building Code, as set forth in Section 2 of this Ordinance, ensure that structures such as fences, retaining walls and signs, that may become potentially dangerous structures in an earthquake or high winds, are constructed in accordance with applicable codes, ordinances and standards; and
3. The amendment to Section 105.6 of Chapter 1 Division II of the 2025 California Building Code, as set forth in Section 2 of this Ordinance, preserves public health, safety and welfare by limiting construction noise and mitigating the effects of having portions of the City’s residential areas constructed on hilly terrain. Many times it is not possible to construct noise barriers between noise sources and noise receptors in hilly areas. Under such circumstances, the "line of sight" between the noise source and the receiver cannot be adequately impeded by other structures such as fences and walls because such structures cannot be constructed on certain lots due to the grade differential between lots; and
4. The addition of Section 105.8 to Chapter 1 Division II of the 2025 California Building Code, as set forth in Section 2 of this Ordinance, is needed to assure that each permit is applicable to the location and conditions for which it was originally obtained; and
5. The amendments to Section 110.3.3.1 and 110.3.6.1 of the 2025 California Building Code, as set forth in Section 3 of this Ordinance, adding additional required inspections, including a sub-frame inspection, a roof sheathing and shear inspection and a plaster inspection assure that all construction and use of buildings conforms to the requirements of the California Building Standards Code in so that maximum protection from the wind, fire and earthquake conditions is provided; and
6. The addition of Section 3109.1.1 to the 2025 California Building Code, as set forth in Section 3 of this Ordinance, isrequired to ensure pool safety and decrease the likelihood of injuries and death due to unauthorized use of pools and the greater use of outdoor swimming pools due to climatic conditions; and
7. The addition of Section 1505.1.3 to the 2025 California Building Code as set forth in Section 3 of this Ordinance and the additions of section R902.1.3 to the 2025 Residential Code as set forth in Section 5 of this Ordinance requires Class "A" roofing which is effective against severe fire exposure, is not readily flammable, affords a fairly high degree of fire protection to roof decks, does not slip from position, and poses no flying-brand hazard, and is
-4-
JAMIER\05100.16000\10315457.8 JAMIER\05100.16000\10315457.8 therefore more fire resistant than other classes of roofing not possessing these characteristics that are adopted for use by the Commission; and
8. The amendments to the 2025 California Fire Code, as set forth in Section 10 of this Ordinance, including the amendments adding definitions to Section 202; the amendment to Section 112.4.2 imposing additional costs against persons responsible for violations of the code; the amendments to Sections 304.1.2, 305.6, 307.6, 307.7, 308.1.6.3, 324, 325, 326, 327, 503.2.1, 503.2.4, 503.7, 505.1, 507.5.1, 507.5.5 507.5.7, 4907.3, 4911 imposing additional requirements for maintenance, clearance and management of vegetation and fuel modification areas, outdoor fires, premises identification, fire access roads, turning radii, clearance around hydrants and other fire apparatus; and amendments to the 2025 California Building Code, as set forth in Section 3 of this Ordinance; and the amendments to the 2025 California Wildland-Urban Interface Code, as set forth in Section 12 of this Ordinance, are needed to minimize the risk of fire which is increased by the climatic, geological and dry brush conditions in the City of Corona, described above in this Ordinance, and to mitigate the spread of fire especially during high wind conditions described above in this Ordinance; and
9. The addition of Section 710 to the 2025 California Fire Code, requiring onehour fire construction for all eaves, as set forth in Section 10 of this Ordinance, is reasonably necessary to mitigate the potential for the spread of fires from flying brands, ashes and sparks during high wind conditions and mitigate potential property damage, injury and death; and
