Subject: Asbestos Inspection Report
To whom it may concern:
Cardinal Environmental Consultants Inc. conducted an asbestos inspection at 4742 Plumosa Dr.
The inspection was requested due to upcoming renovations. This report includes inspection and sample testing of all suspect building materials.
All suspect materials to be impacted by the project were sampled in accordance with the regulations. Sampling methodology, laboratory report, and recommendations can be found on subsequent pages of this report.
Regulatory Compliance:
On August 24th, 2026, Cardinal Environmental Consultants Inc conducted an asbestos survey at 4742 Plumosa Dr. The survey was completed in compliance with the federal AHERA (Asbestos Hazard Emergency Response Act) 40 CFR Part 763 subpart E. The Act indicates procedures for sampling and reporting of asbestos information (about the school) to students, staff, and contractors working on schools where students K through 12 are present. Ronald R McDaniel (CAC 01-2865) conducted this inspection.
Adherence to NESHAP (National Emission Standard for Hazardous Air Pollutants) has been achieved with compliance to South Coast Air Quality Management District’s Rule 1403.
SCAQMD is the local air quality district that regulates and monitors asbestos abatement activity in the region of the buildings.

Sampling Methodology – Asbestos:
Cardinal Environmental Consultants Inc. used several procedures from visual assessments to tangible assessments and a modified random sampling protocol to collect the samples of the suspect asbestos containing material. Cardinal’s sampling procedures incorporate the use of plastic Ziploc bags, labeled with black permanent markers per a unique numbering sequence.
One label with the suspect samples collected for this report was given a unique sample identification number. A second description was placed on the bulk sample log. Information about the sample, including the sample type and location was noted on the sheet as each sample was collected.
Asbestos: Any building material which contains asbestos in an amount greater than 1% by weight, area.
<1% Asbestos: Federal regulations and SCAQMD (South Coast Air Quality Management District) do not regulate asbestos at this percentage. Notifications to these agencies do not apply.
However, OSHA regulations do apply. These are specific to “worker protection” issues. A contractor who is “DOSH certified” is required if removing more than 100 square feet. Federal and State regulations do not regulate the disposal of this type of construction debris with this level of asbestos. However, your local landfill may have a “zero tolerance” for any asbestos containing debris.
Suspect Asbestos-Containing Materials:
Samples of suspect Asbestos-containing materials were taken of the interior and exterior throughout the structure. We were able to collect representative samples of all scope required building materials.
The following materials were tested:
• Linoleum
• Drywall
• Joint Compound
• Pipe Insulation
• Acoustic Ceiling
• Concrete
• Plasterboard
• Asphalt
• Flat Roof Material
• Shingle Roofing
• Roof Penetration Mastic
Results:
All samples were packaged and shipped to EmLab P&K, LLC (NVLAP 200757-0) 2841 Dow Avenue, Suite 300, Tustin, CA 92780 (866) 465-6653. The analysis procedure used to determine the presence of asbestos is outlined in the Code of Federal Regulations 40 CFR part 763, Section 1, Appendix A, Polarized Light Microscopy.
The following tables depict asbestos at the school. The investigator has reviewed the results and construction of the buildings and adjusted the locations and the quantities based on

“homogeneous areas.” AHERA can require the like areas in type, construction, and use (that test positive for asbestos) be combined with other similar areas. Therefore, some areas may not be specifically tested for asbestos but be included in an area of asbestos. Likewise, an area that has tested negative for asbestos could be included in the asbestos table because of the definition of “homogeneous area.”
Subsequent tables in this document depict what was sampled and the outcome of each. Those subsequent tables should be used for clarification and not for quantification of asbestos.
Asbestos:
Material Location Condition Quantity
Pipe Insulation/Duct
Wrap
Basement Good Approx 150sf
Roof Penetration
Mastic
House Roof Good Approx: 50sf
Transite Pipe Basement, Piping Good Approx: 20sf
Summary:
Pipe Insulation:
The pipe insulation/duct wrap is in the basement area.
Transite Pipe:
Transite pipe is in the basement area.
Penetration Mastic:
The penetration mastic is located at multiple penetration sites on the roof area.
Cardinal Environmental aggressively searched all areas and located asbestos containing materials in various areas. Every suspected material was sampled and sent to the laboratory. All asbestos must be removed by a DOSH licensed abatement contractor.

The report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the federal government. The Company reserves the right to dispose of all samples after a period of thirty (30) days, according to all state and federal guidelines, unless otherwise specified.
All components not quantified as asbestos content and non-asbestos content are considered to be non-fibrous matrix components. Matrix components may include, but are not limited to, gypsum, paint, silicate minerals, vinyl, binder, calcium carbonate, tar, and foam.
Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. ND means no fibers were detected. When detected, the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.

Subject: Lead Inspection Report
To whom it may concern:
Cardinal Environmental Consultants conducted a lead inspection at 4742 Plumosa Dr. The survey was requested by the Contractor. All paint systems associated with the project(s) have been sampled in accordance with local and federal regulations. XRF data, sampling methodology and recommendations can be found on subsequent pages of this report.
Regulatory Compliance:
The EPA and the Department of Housing and Urban Development (HUD) have established quantitative standards for lead concentration in painted surfaces. The standard for public housing, above which abatement or removal is required, is 1.0 mg/cm2 or 0.5% lead by weight.
No official standard exists for school buildings. Los Angeles County and L.A. Unified School District are understood to have set a standard of 0.7 mg/cm2 – above which abatement is required. Currently most of the regulations relate specifically to abatement activities.
Generally, HUD (Department of Housing and Urban Development) initiated lead regulations which were then adopted by the state CDPH (California Department of Public Health).
Renovation, Repair and Painting Rule (RRP)
The new regulation outlines procedures for identifying lead paint and completing abatement of lead paint. Additional requirements for certification and clearances are also addressed.
Abatement activity triggers the regulation when paint systems with 1.0mg/C2 or .5% are disturbed.
2 | Page
The new EPA lead regulation, 40CFR 745, Renovation, Repair and Painting Rule (RRP), which became effective April 22, 2010, requires construction professionals to become “Certified Renovators” and firms to become “Certified Firms”. The regulation applies to all contractors, property managers and other building professionals who disturb painted surfaces while conducting plumbing, electrical, painting, drywall, flooring, window replacement, landscaping, construction, renovation, remodeling, and demolition work.
The new rule is instigated when more than six square feet of interior painted surfaces and twenty square feet of exterior surfaces are disturbed. As with HUD and the state adoption of HUD, the rule applies to lead paint systems above (1.0 mg/cm2 as indicated by an XRF device or .5% by weight).
The following is a table that outlines the regulations and requirements for each.

OSHA Compliance:
OSHA (Occupational Safety and Health Administration) through the regulation 1532.1 further delineates requirements for lead activities. 1532.1 defines “trigger tasks” (e.g., manual demolition, etc.) that disturb lead paint and the contractor responsibilities to its employees. The regulation specifically addresses PEL’s (permissible exposure limits) to staff disturbing lead paint. This regulation is initiated when “trigger task” work is implemented on paint systems with .06% or 600 ppm (parts per million). It should be noted that this level (.06%) is virtually any amount of lead paint. As of January 2002, OSHA now requires all contractors to notify the department when disturbing lead paint above 1.0mg/cm2. This level is the same threshold for abatement by HUD.
OSHA requires that the employer is required to protect their employees to the level stipulated in the Standard, or to do an exposure assessment. An exposure assessment is the air monitoring of an employee during lead work to determine his exposure and ultimately to determine the level of protection required. This assessment is applicable to paint systems above .06% or 600 ppm.

Methodology:
The data was developed using an X Ray Diffraction device, which reports lead content in milligrams per square centimeter of surface area (mg/cm2). The reading represents the quantity of lead between the surface and the substrate under the square centimeter of surface area contacted by the test device. If the substrate contains lead, the test result will be affected. (Galvanized metal is an example of this.) A positive reading by the XRF 100% confirms that lead was detected.

The survey at 4742 Plumosa Dr had 78 XRF readings, covering representative building components, substrates, and paint colors on or in the buildings. Subsequent tables illustrate all of the paint systems at the school site. Regulations may apply to other components with lower levels of lead. The contractor is required to review and verify the scope of work for the project and determine the impact of activities on lead painted surfaces (at any level).
Summary/Recommendations:
Depending on the scope of work for the project, contractors should determine the level of contractor licensing for the abatement and/or work disturbing lead paint systems.
We recommend “lead certified” painting contractors for the painting of buildings coated with lead paint. Preparation of these surfaces falls under the “trigger task” category of OSHA 1532.1.
Preparation of painted surfaces and the ultimate “guarantee” of the final painted product is better completed by a “single” contractor.
RRP certified firms should be considered for incidental work that disturbs small amounts of lead paint. These categories of work may include concrete coring (through lead paint) and structure welding (door hinges etc.).
Abatement companies with CDPH (California Department of Public Health) lead certified staff will be required for all abatement work. The companies selected will have to ensure that a certified lead supervisor be present during abatement preparation and be within two hours (response time) during abatement activities.
5 | Page
Painting contractors will be required to collect all paint chips from the preparation activities. The contractor will sample and categorize the waste for disposal. Proof of sampling and waste disposal will be required. Metal components (coated with lead paint) will likely be recycled. A letter (stating acceptance of material) will be required from the contractor’s recycling facility.
All other waste produced from abatement activities will be separated and staged in a safe storage area at the project site during the sampling process. The characterization of the waste can take up to two weeks and an area will need to be allocated for this purpose. The contractor will be required to conduct and pay all costs associated with the characterization of the waste. Copies (proof) of all characterizations of waste will be demanded on completion and before waste transport.
Final Comments:
All materials found to be lead containing must be removed by a CDPH certified abatement company. Please refer to the table above for specified lead containing materials.

CUSTOMER SERVICE EXCELLENCE CONTINUES WITH RECORD
PERFORMANCE METRICS
The San Joaquin Hills Transportation Corridor Agency (SJHTCA) and Foothill/ Eastern Transportation Corridor Agency (F/ETCA) Boards received the Fiscal Year (FY) 2026 Annual Customer Service Report, which highlighted continued excellence in customer service performance, customer feedback, self-service adoption, and account growth.
The report showed significant improvements in operational performance, including a significant reduction in average wait times and a 41% decrease in incoming call volume following the elevated activity experienced during the prior year’s nationwide smishing scam. Customer satisfaction remained strong, achieving the agencies’ goal with a rating of 4.5 out of 5, while more than 143,000 customer surveys were completed during the year.
The Toll Roads customer service center achieved a record Net Promoter Score of 76%, the highest since the survey program was implemented and well above the benchmark for excellence. The report also highlighted continued growth in convenient, self-service options, with more than 527,000 PayNearMe transactions completed and 71% of account management functions handled through self-service channels. Additionally, nearly 195,000 new accounts were added during FY26, helping surpass the milestone of 3 million total accounts. 241/91 EXPRESS CONNECTOR PROJECT—WINDY RIDGE TASK ORDER The F/ETCA Board approved a task order with TransCore to support toll system modifications at the northbound Windy Ridge toll plaza as part of the 241/91 Express Connector Project.
The work will prepare the existing toll collection system for both temporary and final lane configurations needed to support construction of the regionally significant project, which will provide a direct connection between the 241 Toll Road and the 91 Express Lanes. Modifications include relocating existing tolling equipment, removing legacy toll collection infrastructure, and installing upgraded all-electronic tolling equipment to maintain seamless toll collection operations throughout construction.
TransCore will perform the highly complex work in coordination with the project’s civil construction activities. The phased improvements will ensure continuity of revenue collection while accommodating construction activities scheduled to begin in late 2026.
ENHANCING CUSTOMER ENGAGEMENT TECHNOLOGY THROUGH NEW
CLOUD SERVICES CONTRACT
A contract with CallTower, Inc. for Genesys Cloud licensing and support services was approved by the Boards of Directors, ensuring continued operation and enhancement of the Agencies’ customer engagement platform that supports customer service phone operations, interactive voice response (IVR), digital channels, reporting, and analytics.
CallTower was unanimously identified as the highest-ranked firm and determined to provide the best overall value for the Agencies. The firm demonstrated strong expertise in Genesys Cloud services, managed support, platform administration, and advanced artificial intelligence capabilities that can support future customer service initiatives.
The new agreement will provide ongoing technical support, subscription management, platform monitoring, incident management, and assistance with emerging AI-driven customer service tools. The contract also delivers a 25% reduction in unit pricing compared to the Agencies’ current service agreement. The proposed contract will help maintain reliable customer service operations while providing opportunities to leverage new technologies to enhance the overall customer experience.

EXECUTIVE SUMMARY:
State housing law requires that SCAG conduct the Regional Housing Needs Assessment (RHNA) process every 8 years. At the start of each RHNA cycle, the California Department of Housing and Community Development (HCD) issues a Regional Housing Needs Determination (RHND) to each Council of Government (COG). The RHND for the upcoming 7th RHNA cycle has not yet been issued and is expected to be provided to SCAG by HCD by October 2026.
To provide background and context for the release of the RHND and 7th cycle RHNA, SCAG has invited David Zisser, Deputy Director for Housing Policy Development, Melinda Coy, Assistant Deputy Director for Housing Accountability, and Zach McRae, Deputy Director for Fair Housing and Tribal Affairs to provide a presentation.
BACKGROUND:
The Regional Housing Needs Assessment (RHNA) is a state-mandated planning process authorized under California Government Code Section 65584. The RHNA process occurs in eight-year planning cycles and is intended to ensure that local governments plan for adequate housing to meet current and future demand at all income levels. Cities and counties are responsible for planning for their assigned housing need through their Housing Element.
At the start of each RHNA cycle, the California Department of Housing and Community Development (HCD) issues a Regional Housing Needs Determination (RHND) to each Council of Government (COG).
In making the regional determination, HCD consults with the relevant COG and the California To: RC - Regional Council

AGENDA ITEM 12
213
REPORT
Department of Finance (DOF) and considers a range of factors set forth in statute, including population projections, household growth, vacancy rates, overcrowding, housing cost burden, and the relationship between jobs and housing. HCD is responsible for determining the total housing need for the region, while the COG is responsible for developing and adopting a methodology to allocate that regional need among individual jurisdictions.
For the current 6th RHNA cycle, covering the planning period from October 2021 through October 2029, HCD determined a total regional housing need of 1,341,827 units for the SCAG region. The RHND for the upcoming 7th RHNA cycle has not yet been issued and is expected to be provided to SCAG by HCD by October 2026.
Once the regional determination is received, SCAG develops an allocation methodology to distribute the housing need to cities and counties throughout the region. The methodology adopted by the COG can vary by cycle and differ from methodologies adopted by other COGs. Following approval of the final methodology, SCAG will release draft RHNA allocations to jurisdictions and begin the appeals process.
The appeals process begins after SCAG distributes the draft RHNA allocation to jurisdictions.
Jurisdictions may file an appeal on the draft allocation of their own jurisdiction or on any other jurisdiction. HCD may also file an appeal on a draft allocation. Filed appeals will be reviewed and determined by the RHNA Subcommittee as part of a public hearing. Decisions made by the RHNA Subcommittee are considered final and are not subject to further action by the CEHD Committee and Regional Council. Per statute, any reductions granted from successful appeals must be reallocated back to the region to ensure that the final RHNA allocation by income levels are maintained for the region.
Changes from the appeals process and any associated reallocation of units will be folded into the final RHNA allocation. The final RHNA allocation will be ultimately adopted by the Regional Council and then transmitted to HCD for final approval. Jurisdictions will then be required to plan and zone for their assigned housing need through their Housing Elements for the 2029–2037 planning period.
Jurisdictions are required to update their Housing Element to accommodate their RHNA allocation through sites and zoning analysis and other programs. Jurisdictions are not directly penalized if the units are not built during the planning period, though they must ensure that the sites are available for development and ensure adequate sites to accommodate RHNA through the end of the planning period.
The final RHNA allocation is anticipated to be adopted in April 2028 by the SCAG Regional Council.
Housing elements for jurisdictions in Riverside, Orange, San Bernardino, and Ventura Counties are
214
REPORT
due in October 2029. Due to recent legislation, Housing Elements for jurisdictions in Los Angeles and Imperial Counties are due in April 2030.
Concurrent to SCAG’s RHNA process, Government Code 65584.03 allows for two or more jurisdictions (two or more cities or unincorporated counties or any combination of them) that are geographically contiguous to form a subregional entity for RHNA purposes, also known as subregional delegation.
The “subregion” would be assigned a share of SCAG’s regional housing need determination. It then develops its own methodology, subject to HCD approval, and conducts its own appeals process. Its final RHNA allocations for the subregion are then folded back into SCAG’s final RHNA allocation.
Subregional delegation is subject to the same requirements of RHNA statute as the COG, including furthering statutory objectives and HCD review and approval of the methodology. SCAG staff will provide more information about subregional delegation at an upcoming RHNA Subcommittee meeting.
Legal Framework and Statutory Requirements
Legal Framework: What State Law Requires
California Government Code Section 65584 establishes the legal framework for the RHNA process.
The statute assigns responsibility to HCD to determine each region’s housing need, and requires COGs to develop a methodology for allocating that need to local jurisdictions. The RHNA methodology and resulting allocation plan must be developed in a manner that is consistent with state law and that advances all five of the following statutory objectives:
1. Increasing the housing supply and the mix of housing types, tenure, and affordability in all cities and counties within the region in an equitable manner, which shall result in each jurisdiction receiving an allocation of units for low- and very low-income households. The regional housing needs allocation plan shall allocate units for extremely low and acutely low income households in a manner that is roughly proportional to, and within a range of 3 percent of, the housing need for very low-income households.
2. Promoting infill development and socioeconomic equity, the protection of environmental and agricultural resources, the encouragement of efficient development patterns, and the achievement of the region’s greenhouse gas reductions targets provided by the State Air Resources Board pursuant to Section 65080.
3. Promoting an improved intraregional relationship between jobs and housing, including an improved balance between the number of low-wage jobs and the number of housing units affordable to low-wage workers in each jurisdiction.
4. Allocating a lower proportion of housing need to an income category when a jurisdiction already has a disproportionately high share of households in that income category, as compared to the
215
REPORT
countywide distribution of households in that category from the most recent American Community Survey.
5. Affirmatively furthering fair housing.
Required Methodology Factors
State law does not provide SCAG with unlimited discretion to develop a RHNA methodology. It requires COGs to develop the methodology in consultation with HCD and consider factors in Government Code Section 65584.04(e) such as jobs-housing relationships, projected household and employment growth, access to transit and existing transportation infrastructure, availability of land suitable for residential development, infill and increased-density opportunities, infrastructure constraints, environmental and agricultural resource constraints, climate-related risks, fair housing, and access to opportunity where sufficient data is available.
State law also restricts considering several factors as a basis for reducing a jurisdictions RHNA allocation. These include local ordinances or standards that limit the number of residential building permits issued, underproduction of housing from previous RHNA cycles, and stable population numbers. The methodology must further the statutory RHNA objectives and be applied uniformly across the region. After developing a proposed methodology with the RHNA Subcommittee and conducting a public comment process, SCAG will develop a draft methodology and submit it to HCD for review. After HCD’s review and SCAG revising the draft methodology with any necessary revisions to receive HCD’s approval, the final methodology will be considered through SCAG’s committee process, including review and approval by the RHNA Subcommittee, CEHD Committee, and Regional Council.
Statutory Changes for the 7th Cycle
Since adoption of the 6th Cycle RHNA allocation plan, the Legislature has enacted several statutory changes that will affect the development of the 7th Cycle RHNA process. These changes influence the RHND, RHNA methodology, and overall timeline:
• Earlier RHND - HCD is now required to determine a region's housing need three years prior to the statutory housing element deadline, rather than two years prior as required in previous cycles (AB 1275).
• Homelessness - State law now requires HCD to consider the housing needs of individuals and families experiencing homelessness when determining the RHND. SCAG is required to provide this information on homelessness to inform HCD’s determination (AB 3093). • Cost Burdened and Overcrowded Households – HCD will now compare the percentage of cost burdened and overcrowded households to national rates, rather than to comparable regional housing markets, when determining the RHND (AB 130).
216
REPORT
• New Income Categories – RHNDs, RHNA allocations, and housing elements must include separate categories for acutely low-income and extremely low-income households. As a result, jurisdictions will now plan for six income categories rather than the traditional four categories used in prior RHNA cycles (AB 3093).
• Student Housing - Recent legislation requires consideration of enrollment growth at University of California (UC) and California State University (CSU) campuses as part of both the RHND and RHNA processes (SB 486).
• Climate Factors – State law requires SCAG to consider including climate-related factors, such as wildfire risk, evacuation constraints, and sea-level rise, when developing the RHNA methodology (AB 1445).
• Sustainable Communities Strategy - Whereas prior law required RHNA allocations to be consistent with the development pattern in the Sustainable Communities Strategy (SCS), the 7th Cycle only requires that the RHNA plan is informed by the SCS (AB 1275). • Subregional Allocation - Changes to state law require that subregions receive a share of the regional housing need that is proportional to their share of the adopted RHNA plan from the previous cycle (AB 1275).
• Expanded HCD Oversight – If HCD determines that SCAG’s proposed methodology fails to further RHNA objectives, SCAG must revise its methodology in consultation with HCD before proceeding (AB 1275).
• Streamlined RHNA Timelines - HCD's review period for an adopted RHNA methodology has been reduced from 90 days to 45 days, and its review period for the final RHNA allocation plan has been reduced from 30 days to 15 days. Additionally, the timeframe for jurisdictions to file RHNA appeals has been reduced from 45 days to 30 days, and the public notice period for RHNA appeal hearings has been reduced from 21 days to 10 days (SB 7) Roles and Responsibilities
HCD
HCD is responsible for determining the total regional housing need that must be accommodated during each RHNA planning cycle. In developing the RHND, HCD consults with SCAG and DOF and evaluates demographic and housing data. HCD also reviews the proposed RHNA methodology developed by SCAG to ensure that it is consistent with statutory requirements and furthers all five statutory objectives. Once SCAG adopts a final RHNA Allocation Plan, HCD oversees local Housing Element compliance and reviews jurisdictions' Housing Element updates.
SCAG
SCAG is responsible for allocating the region's housing need among its member jurisdictions.
Following receipt of the RHND, SCAG develops a RHNA methodology in consultation with HCD and in accordance with state law, including obtaining HCD approval of the methodology. The methodology must further the statutory RHNA objectives and consider the methodology factors identified in
217
REPORT
Government Code Section 65584.04. SCAG conducts public outreach, solicits input from jurisdictions and stakeholders, develops a draft allocation plan, administers the appeals process, and ultimately adopts the final RHNA Allocation Plan for the region.
RHNA Subcommittee
The RHNA Subcommittee plays a key role in SCAG’s RHNA process by providing policy guidance, reviewing key materials, supporting robust and transparent public discussions, and shaping recommendations to SCAG’s CEHD Committee and Regional Council. Its primary responsibilities will include developing the proposed RHNA methodology, overseeing the release of the draft and proposed final RHNA allocations, and hearing appeals related to draft RHNA allocations. The Subcommittee may not modify HCD's RHND or override statutory requirements governing the RHNA process. Decisions made by the RHNA Subcommittee will serve as recommendations to SCAG’s CEHD Committee and Regional Council, except the RHNA Subcommittee will make the final decisions regarding all appeals of draft RHNA allocations.
Local Jurisdictions
Local jurisdictions influence the RHNA process by participating in surveys to develop the proposed methodology and public comment opportunities. Jurisdictions also have the opportunity to review the proposed methodology and provide feedback during the public review process. Following release of the draft RHNA Allocation Plan, local jurisdictions may file appeals consistent with the procedures established in state law. Once SCAG adopts a final RHNA Allocation Plan, each jurisdiction is responsible for updating its Housing Element to accommodate its assigned share of the region's housing need across all income levels during the planning period.
What SCAG Can Influence vs. What SCAG Must Follow
SCAG is responsible for developing a RHNA methodology that distributes the region's housing need among local jurisdictions. In carrying out this responsibility, SCAG must comply with state housing law by advancing the statutory RHNA objectives, utilizing the final RHND, following required public participation and appeals procedures, and addressing HCD comments on the proposed methodology.
SCAG can appeal to reduce the RHND, but HCD has the responsibility of making the final determination. SCAG cannot disregard statutory requirements, or adopt a methodology that is contrary to state law or applied inconsistently across the region.
Within these requirements, however, SCAG has discretion in how it designs the RHNA methodology.
This includes selecting and applying data sources, determining the weighting of methodology factors, incorporating public and local jurisdiction feedback, and deciding how statutory objectives are reflected in the allocation approach. SCAG may also help inform the RHND through consultation with HCD before the regional determination is finalized.

PUBLIC WORKS DEPARTMENT
DATE: OCTOBER 6, 2026
TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: JAMIE LAI, P.E., DIRECTOR OF PUBLIC WORKS/CITY ENGINEER PREPARED BY: RICK YEE, P.E., DEPUTY PUBLIC WORKS DIRECTOR SUBJECT: ADOPT RESOLUTION NO. 2026-6008 TO ACQUIRE PROPERTY AT 22401
OLD CANAL ROAD FOR THE SAVI RANCH PARKWAY IMPROVEMENT
PROJECT
RECOMMENDATION
Adopt Resolution No. 2026-6008 determining that the public interest and necessity require the City to acquire property interests at 22401 Old Canal Road, and authorizing condemnation of those interests for the Savi Ranch Parkway Improvement Project.
SUMMARY
The Savi Ranch Parkway Improvement Project will increase vehicle capacity, improve pedestrian walkways and maximize circulation along Savi Ranch Parkway between Yorba Linda Boulevard and Mirage Street. The City must acquire portions of the landscaped slopes at 22401 Old Canal Road to construct these improvements. The property is leased to Sprouts Farmers Market. The project will not require the relocation of any residents or businesses.
The recommended resolution finds that the City has fulfilled the necessary prerequisites to exercise eminent domain to acquire the required property and doing so serves the public interest. Negotiations with the property owner are ongoing and the compensation terms are not a necessary part of the resolution.
DISCUSSION
The City intends to acquire a permanent roadway and public utility easement of approximately 9,576 square feet and a temporary construction easement of approximately 16,885 square feet from the property to accommodate the project’s improvements to the public roadway and pedestrian facilities. The permanent easement will affect existing landscape slope areas, while the temporary construction easement will affect 19 existing parking spaces during a portion of construction. The temporary construction easement will have a term of up to 36 months, including a six-month exclusive-use period during physical
RESOLUTION NO. 2026-6008 SAVI RANCH PARKWAY IMPROVEMENT construction. Reasonable and safe pedestrian and vehicular access to the remainder of the property will be maintained throughout construction. The property’s tenant, Sprouts Farmers Market, will remain fully operational throughout the project.
Pursuant to Government Code § 7267.2, the City obtained an appraisal and submitted an initial offer to the property owner, Yorbook, LLC, on May 6, 2026. Since then, Public Works and the City’s Right-of-Way Agent have made concerted efforts to negotiate with the owner’s legal representative. In response to concerns regarding the temporary easement limits, the City reduced the easement area, obtained a revised appraisal, and submitted a revised offer on September 11, 2026. At the owner’s representative’s request, the easement limits were also staked in the field, and the City held a meeting with all parties to address questions and clarify the project.
Resolution No. 2026-6008 is a resolution of necessity under California Code of Civil Procedure §§ 1245.210, et seq. Such a resolution must be considered and approved by the legislative body prior to any exercise of eminent domain to acquire property. Pursuant to Code of Civil Procedure § 1245.240, the resolution must be passed by a two-thirds vote of all the members of the City Council, which is four affirmative votes.
The California Eminent Domain Law provides the findings that must be made in a resolution of necessity. These are:
That the public interest and necessity require the project for which the property is recommended to be acquired;
That the project is planned or located in the manner that will be most compatible with the greatest public good and the least private injury;
That the property recommended to be acquired is necessary for the project; and That the offer required by Government Code § 7267.2 has been made to the owner of record.
In addition, the recommended resolution finds that the City has met all other procedural prerequisites for the exercise of eminent domain on the property, including a determination that the City reviewed the project under applicable environmental review procedures. The project’s environmental impacts were reviewed in connection with a Mitigated Negative Declaration approved on January 19, 2021. Additionally, the Planning Commission determined on May 14, 2025, that the City’s acquisition of the property is consistent with the City’s General Plan pursuant to Government Code § 65402.
The property owner, and/or their representative, has a right to appear and be heard on the matters encompassed within the resolution affecting their property. As required by the California Eminent Domain Law, the City gave the property owner notice of the City Council’s consideration of the resolution of necessity, and of the opportunity to appear and be heard on whether the City has undertaken all required steps and met all procedural prerequisites to the exercise of eminent domain.
RESOLUTION NO. 2026-6008 SAVI RANCH PARKWAY IMPROVEMENT The facts supporting the various prerequisite findings are included with greater detail within the resolution of necessity. Generally, the public interest and necessity require the project, because it is designed to improve vehicle circulation through Savi Ranch Parkway. The project is located in a manner most compatible with the greatest public good and least private injury because the permanent acquisition areas on the property are limited to portions of the slope that do not impact the functional use of the property. Additionally, the project is designed in a manner compatible with the greatest public good because the project will improve overall circulation for both vehicles and pedestrians and enhance the utility of the area.
Negotiations remain ongoing but the parties have not yet reached a final agreement for the acquisition of the property interest. Public Works will continue to pursue a mutually agreeable resolution. The amount of compensation due for the property interests involved is not a subject of the resolution of necessity, and therefore not before City Council as an issue to be considered as part of this resolution.
If the City Council adopts the recommended resolution, the City will initiate eminent domain proceedings which will lead to a determination of the fair market value of the property interests recommended to be taken through court proceedings. If City Council does not adopt the resolution, the City will risk potential loss of federal funding as the milestone delivery date for completing the right-of-way phase may not be met.
FISCAL IMPACT
If the City Council initiates eminent domain proceedings, the City must deposit the appraised value of the property interests with the State Treasurer’s Office. The City’s independent appraisal valued the property interests at $276,000 as of September 2026.
If the matter proceeds to court, the City will also incur legal, appraisal and court costs. The court will determine the final compensation for the property interests.
The project budget includes sufficient funding to complete the necessary property acquisition through negotiation or eminent domain.
ALTERNATIVES
Do not approve the recommendation and provide alternative direction.

WHEREAS, the Project for which the Property is to be acquired was reviewed under applicable environmental review procedures, including completion of a Mitigated Negative Declaration in January 2021; and
WHEREAS, the City is hereby authorized and empowered to acquire the Property by eminent domain for the proposed Project in accordance with Code of Civil Procedure section 1230.010 et seq., Government Code sections 37350.5 and 40404, the Constitution of California, and California Eminent Domain Law.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Yorba Linda, California, that the City Council does hereby find, determine and declare upon evidence presented to the City Council as follows:
SECTION 1. The Project for which the property is being acquired is the Savi Ranch Parkway Improvement, which consists of providing improved vehicular capacity and pedestrian improvements along Savi Ranch Parkway between Yorba Linda Boulevard and Mirage Street while also improving circulation at the respective intersections. The City is authorized to acquire the property interests described herein by eminent domain pursuant to Code of Civil Procedure section 1230.010 et seq. and Government Code sections 37350.5 and 40404.
SECTION 2. The Property to be acquired is located at 22401 Old Canal Road, Yorba Linda, California (APN 352-113-01 and 352-113-02). The portions of Property the City seeks to acquire, and the Property interests sought, consist of the following:
A. A permanent roadway and public utility easement consisting of approximately 9,576 square feet, as legally described in the exhibit attached hereto as Exhibit 1 and depicted in the diagram attached as Exhibit 2. The permanent roadway and public utility easement interest sought to be acquired over this portion of the Property consists of the following:
A perpetual easement for public right-of-way and roadway purposes, including all use of the easement area for purposes incident to public rightof-way use, including but not limited to the construction, maintenance, and operation of a roadway, underground and above-ground utilities and appurtenances, cable communication or telecommunication facilities, directional, street identification or motorist or pedestrian informational signage, traffic control devices, curbs, gutters, sidewalks, landscaping, drainage and sewage facilities, and transportation facilities such as bus bays, benches, bus or train stops, bicycle pathways, or facilities for other public transportation vehicles or manners of conveyance.
R E S O L U T I O N N O . 202 6 - 6 0 0 8
P A G E 3
B. A temporary construction easement over approximately 16,885 square feet of the Property, legally described in Exhibit 3 and depicted in Exhibit 4 hereto. The temporary construction easement shall consist of the interests described below:
The temporary construction easement is a non-exclusive easement for a period of thirty-six (36) months, which includes a six (6) consecutive month exclusive-use period during actual physical construction (the “Construction Period”), and which permits the City of Yorba Linda, its officers, agents, employees, and contractors, to enter upon, occupy, and pass over the temporary construction easement area more specifically described in the legal description attached as Exhibit 3, as deemed reasonably necessary for all purposes incidental to the Project. The six (6) month Construction Period refers solely to the duration of time during which the temporary construction easement area will be used exclusively for construction activities, and not to any separate or reduced physical portion of the temporary construction easement area. For the remainder of the thirty-six (36) month term outside the Construction Period, the temporary construction easement shall be non-exclusive. During the Construction Period, and only during the Construction Period, the temporary construction easement shall include the right to perform within the temporary construction easement area any necessary excavation, grading, earth fill, compaction, installation of concrete forms, landscaping, irrigation, utility, and sign relocation, accommodation of private drainage facilities, and deposit of tools, equipment, and material for all such necessary activities which are reasonably incidental to the work being performed on said property in connection with the Project. Outside the Construction Period, the City’s use of the temporary construction easement shall be limited to non-exclusive entry and passage as reasonably necessary for purposes incidental to Project planning, and shall not include the right to conduct active physical construction activities of the kind enumerated above within the temporary construction easement area.
Such incidental activities during the Construction Period shall include, but not be limited to, utilizing the easement area for adjusting grade differentials between the planned street and the adjoining real property and/or matching existing concrete and/or asphalt paved areas, and/or natural grade areas; removal and reconstruction of walkways and pavement; re-establishment of landscaping and irrigation; and pedestrian access; or such work as may pertain to on-site improvements to render the easement area or the larger parcel to which it pertains in the same functional condition as reasonably practicable to the condition before the Project.
Access to the temporary construction easement area shall be from the public right-of-way. At the commencement of the Construction Period, the City may place a temporary fence around the temporary construction
R E S O L U T I O N N O . 202 6 - 6 0 0 8
P A G E 4
easement area; provided, however, that no fence shall be placed in such a manner as to impede reasonable access around or across any driveway.
Throughout the term of the temporary construction easement, including the Construction Period, reasonable and safe pedestrian and vehicular access to the remaining property outside of the temporary construction easement area shall be maintained, and the temporary construction easement shall not be exercised in a manner that would deprive the remaining property of reasonable access to the public right-of-way.
The temporary construction easement shall not include the right to store any materials or park any vehicles which are not incidental to the work to be performed on site in connection with the Project, nor to block vehicular access to the larger parcel of property of which the temporary construction easement area is a part, nor to exercise the uses of the easement outside of the temporary construction easement area.
The City shall provide the owner(s) and occupant(s) of the Property a minimum of thirty (30) days’ written notice as to when the Construction Period will commence. The rights granted hereunder shall continue in full force and effect until written notice to the owner of record that the temporary construction easement is no longer needed by the City, or thirty-six (36) months after notice of the initiation of the temporary construction easement, whichever is earlier. Upon termination of the Construction Period, the temporary construction easement area shall be restored to a condition that is as functionally equivalent as is practicable to its condition prior to the commencement of the work, consistent with the Project as designed and as to be constructed.
SECTION 3. The public interest and necessity require the Project, in that the Project is designed to provide for improved vehicle circulation through Savi Ranch Parkway and adjoining intersections at Yorba Linda Boulevard and Mirage Street.
Improvements include adding a traffic lane between Mirage Street and Yorba Linda Boulevard, enhancing key turn movements, and streamlining traffic flow to reduce congestion.
SECTION 4. The Project is located in a manner most compatible with the greatest public good and least private injury, in that the permanent acquisition areas on the Sprouts property are limited to slivers of the existing slope that do not impact the functional use of the property, and the temporary construction easement is designed to preserve reasonable and safe access to the remaining property throughout construction. The Project is designed in a manner compatible with the greatest public good, in that the Project will provide improved circulation for both vehicles and pedestrians. This will enhance the utility of the area and alleviate congestion, improve safety and overall traffic circulation. The Project will not require the relocation of any businesses or residents.
R E S O L U T I O N N O . 202 6 - 6 0 0 8
P A G E 5
SECTION 5. The Property is necessary for the proposed Project, in that widening must occur on property immediately adjacent to the existing roadway and the improvements could not be accomplished without the aforementioned property acquisition. This will enhance the utility of the area and help improve traffic circulation.
SECTION 6. The offer required by Government Code section 7267.2(a), together with the accompanying statement of, and summary of the basis for, the amount established as just compensation, has been made to the record owners, by way of letter dated September 11, 2026. Staff has attempted to negotiate with the record owners subsequent to this offer, but such negotiations have not proved successful in securing the necessary property interests outside of more formal proceedings.

FOR (DATE OF COUNCIL MEETING): October 6, 2026
“OTHER BUSINESS” ITEM TO BE AGENDIZED:
TITLE OF REPORT/ ITEM:
Direct the City Manager to Develop a Recommendation to Install a Flagpole at Black Gold Golf Club
ADDITIONAL INFORMATION:
A resident recently brought to my attention that the City has never installed a flagpole to fly the flag of the United States at Black Gold Golf Course. As we celebrate 250 years of American independence, I believe the City Council should consider amending the FY 2026- 27 Capital Improvement Budget to include building a flagpole at the City’s golf club.
I respectfully request your support to direct the City Manager to develop a recommendation to the City Council to install a flagpole at Black Gold Golf Club. The recommendation should return to the City Council before the end of the year (if practical) and should include the flagpole location, project cost and funding source, and schedule.
