REQUEST FOR CITY COUNCIL ACTION
SUBJECT:

PROFESSIONAL SERVICES AGREEMENT WITH MARK THOMAS & COMPANY, INC.

TO PROVIDE TRAFFIC CORRIDOR IMPACT STUDY AND DESIGN SERVICES FOR

THE ONTARIO AVENUE WIDENING PROJECT
EXECUTIVE SUMMARY:

This staff report asks City Council to approve the Professional Services Agreement with Mark Thomas & Company, Inc. in the amount $2,511,906 for Traffic Corridor Impact Study and Design Services related to the Ontario Avenue Widening Project.

RECOMMENDED ACTION:

That the City Council:
a. Award Request for Proposal No. 26-004SB to Mark Thomas & Company, Inc. to provide Traffic Corridor Impact Study and Design Services for the Ontario Avenue Widening Project No. 2017-11.
b. Approve the Professional Services Agreement with Mark Thomas & Company, Inc. to provide Traffic Corridor Impact Study and Design Services for the Ontario Avenue Widening Project No. 2017-11 in the amount of $2,511,906, and waive any minor irregularities in the proposal.

Page 247 of 707 ends

c. Authorize the City Manager, or his designee, to execute the Professional Services Agreement with Mark Thomas & Company, Inc., in the amount of $2,511,906, including any non-substantive extensions, change orders, purchase orders, and amendments up to $251,191 or 10%.

BACKGROUND & HISTORY:

Ontario Avenue is a key east-west road in Corona, providing access to Interstate 15 and local neighborhoods. Since 2017, widening between Compton Street and State Street has been important due to safety, congestion, and improved mobility, as identified in city and regional plans. Studies revealed lane reductions and missing pedestrian facilities caused bottlenecks and safety concerns, and recommended upgrades for accessibility and congestion relief. To advance the project, Corona partnered with RCTC and Caltrans, securing funding through agreements and grants, including support from mitigation programs tied to the Express Lanes on State Route 91.

In the course of project development for the Ontario Avenue Widening, the City of Corona has previously engaged multiple professional service providers to advance the corridor’s technical studies and design. Notably, in November 2018, the City Council awarded a Professional Services Agreement to KOA Corporation for Traffic Corridor Impact Study and Design Services for the Ontario Avenue Widening, following a formal competitive solicitation process. The agreement with KOA Corporation was intended to deliver comprehensive design and environmental documentation to support the City’s objectives for the corridor, and the firm was selected based on its qualifications and proposal ranking at that time.

Despite initial progress, the City determined that KOA Corporation was unable to meet the performance standards and delivery timelines required under the terms of the agreement. The City’s contract administration procedures, as established by municipal code and standard professional services agreements, provide for the termination of contracts in the event of non-performance or failure to achieve critical project milestones.

In accordance with these provisions, the City exercised its right to terminate the agreement with KOA Corporation due to lack of performance, thereby ensuring that project delivery risks were mitigated and that public resources were managed in a manner consistent with City policy and fiduciary responsibility.

Following the termination of the KOA Corporation agreement, the City initiated a new competitive procurement process to secure a qualified consultant capable of meeting the technical, regulatory, and schedule requirements for the Ontario Avenue Widening project. This transition was managed to maintain compliance with all applicable municipal and state procurement statutes and to minimize disruption to the project’s overall timeline.

The subsequent selection and engagement of a new consultant was based on a rigorous evaluation of qualifications, experience, and demonstrated capacity to deliver federally funded transportation projects in accordance with City and agency standards.

This sequence of events underscores the City’s commitment to effective contract management and project oversight, as well as its adherence to established legal and

Page 248 of 707 ends

administrative frameworks governing the procurement and administration of professional services for capital improvement projects.

In summary, the Ontario Avenue Widening Project represents a multi-year, multi-agency effort to address longstanding transportation challenges in a key corridor. The project’s history reflects a sustained commitment to intergovernmental collaboration, technical rigor, regulatory compliance, and community responsiveness, all aimed at delivering a safer, more efficient, and more accessible transportation facility for the residents and businesses of Corona and the surrounding region.

ANALYSIS:

The Purchasing Division issued Request for Proposal (RFP) No. 26-004SB for Traffic Corridor Impact Study and Design Services for the Ontario Avenue Widening Project on October 30, 2025, in accordance with the formal competitive solicitation procedures set forth in Corona Municipal Code (CMC) Section 3.08.110, which requires public notice and a transparent, competitive process for the procurement of professional services exceeding the formal bid threshold. Notice of the RFP was posted on the City’s electronic bidding portal, PlanetBids, and made available to all registered vendors. Additionally, the RFP was advertised in the Sentinel Weekly News on October 30, 2025, to ensure broad public awareness and compliance with statutory notice requirements. Proposals were due by December 1, 2025, at 5:00 p.m.

A total of four proposals were received by the deadline. The evaluation process was conducted by a Selection Committee comprised of City staff. Each proposal was independently reviewed and scored based on the criteria established in the RFP, which included: (1) Understanding of the work to be done, (2) Experience with similar kinds of work, (3) Quality of staff for the work to be done, (4) Familiarity with state and federal procedures, and (5) Financial responsibility.

The following table summarizes the proposals received and their final evaluation ranking:

Firm Name Evaluation Rank
Mark Thomas & Company, Inc. 1
David Evans & Associates, Inc. 2
EXP U.S. Services, Inc. 2
Wood Rodgers, Inc. 3
Mark Thomas & Company, Inc. was selected as the top-ranked firm based on its demonstrated expertise in corridor impact studies and federally funded transportation projects, the strength and experience of its proposed project team, and its comprehensive approach to meeting the City’s technical, regulatory, and schedule requirements. The Selection Committee determined that Mark Thomas & Company, Inc. provided the best value and was most qualified to deliver the full scope of services, including environmental

Page 249 of 707 ends

documentation, right-of-way engineering, and construction support, in compliance with all applicable municipal, state, and federal standards.

The Ontario Avenue Widening Project is consistent with the City of Corona General Plan, the City’s Strategic Plan, and the Western Riverside Council of Governments’ Transportation Uniform Mitigation Fee (TUMF) program. The project supports the City’s goals to improve circulation, reduce congestion, enhance multimodal mobility, and ensure public safety. It also aligns with regional transportation objectives and funding strategies identified by the Riverside County Transportation Commission (RCTC) and the Southern California Association of Governments’ Regional Transportation Plan/Sustainable Communities Strategy.

Based on the results of the competitive evaluation and the alignment of the project with adopted master plans and strategic objectives, staff recommends that the City Council approve the agreement for City Council consideration to approve a Professional Services Agreement with Mark Thomas & Company, Inc. to provide Traffic Corridor Impact Study and Design Services for the Ontario Avenue Widening Project in the amount of $2,511,906; and award RFP No. 26-004SB.

FINANCIAL IMPACT:

Funding for the recommended actions is available in the Ontario Avenue Widening/I15 Multimodal Corridor Enhancement Capital Improvement Project No. ST-2017-04 within Public Works Grants/Agreement Fund 243.

The estimated design cost for this Project is outlined as follows:

Design
…………………………………………………………………………………………………. $
2,511,906
Contingency
……………………………………………………………………………………………. $
251,191
Total Cost
……………………………………………………………………………………….…
$2,763,097
The agreement with Mark Thomas & Company, Inc. is incorporated into the project which is fully funded for the current design and pre-construction phases. The City’s financial strategy for this project emphasizes leveraging outside funding to maximize the return on local investment, with ongoing efforts to secure additional state and federal grants for future construction phases. The use of grant and mitigation fee revenues for this contract ensures that the project remains consistent with the City’s adopted Capital Improvement Plan and does not adversely affect funding for other priority projects.

ENVIRONMENTAL ANALYSIS:

These actions are exempt from the California Environmental Quality Action (CEQA), as the actions are not a “project” as defined by CEQA (PRC Section 21065 and CEQA Guidelines Section 15378), guidelines which define a “project” as the whole of an action, which has a potential for resulting in either a direct physical change in the environment, or reasonable foreseeable indirect physical change in the environment, and that is an activity directly undertaking by any public agency including public works construction and related activities. These actions involve the approval of a professional services agreement. Therefore, no environmental analysis is required at this time. After approval of the recommended actions herein, staff will proceed with the design and environmental document phase of this project. Any applicable documentation will be prepared and filed at that time.

understands, acknowledges and agrees that the following provisions shall apply and that failure to comply shall be considered to be a breach of this Agreement by Consultant:
(A) Waiver of Subrogation – All Other Policies. Consultant hereby waives all rights of subrogation any insurer of Consultant’s may acquire against the City, its directors, officials, officers, employees, agents, and volunteers for losses paid under the terms of any insurance policy which arise from work or Services performed by the Consultant.

Consultant understands, acknowledges and agrees that this provision is in full force and effect even if the City does not receive a waiver of subrogation endorsement from the insurer. (B) Notice. Consultant shall either: (1) require its insurer to provide thirty (30) days prior written notice to the City before coverage is suspended, voided, or canceled; or (2) notify City in writing that such notice is not available and forward any notice of such actions to the City within two (2) business days from date of receipt by Consultant. Consultant understands, acknowledges and agrees that this provision is in full force and effect even if the City does not receive a waiver of subrogation endorsement from the insurer.

3.2.10.6 Claims Made Policies. The following provisions shall apply to all policies that provide coverage on a claims-made basis: (A) the retroactive date must be shown and must be before the date on which any Services under this Agreement commence; (B) the insurance must be maintained and evidence of insurance must be provided for at least five (5) years after completion of the Project; and (C) if coverage is canceled or not renewed and is not replaced with another claims-made policy with a retroactive date prior to the date on which any Services under this Agreement commence, Consultant must purchase “extended reporting” coverage for a minimum of five (5) years after completion of Project.

3.2.10.7 Deductibles and Self-Insurance Retentions. Any deductibles or self-insured retentions must be declared to and approved by the City. The City may require the Consultant to provide proof of ability to pay losses and related investigation, claims administration and defense expenses within the deductible or self-insured retention. The deductible or self-insured retention may be satisfied by either the named insured or the City.

3.2.10.8 Acceptability of Insurers. Unless under the circumstances a different rating is otherwise acceptable to the City in its sole and absolute discretion, insurance is to be placed with insurers which are satisfactory to the City and which meet either of the following criteria : (1) an insurer with a current A.M. Best’s rating no less than A-:VII and licensed as an admitted insurance carrier in California; or (2) an insurer with a current A.M. Best’s rating no less than A-:X and authorized to issue the required policies in California.

3.2.10.9 Verification of Coverage (Initially & Annually). Consultant shall furnish City with original certificates of insurance, as well as amendatory endorsements or copies of the applicable policy language effecting coverage required by this Agreement.

Consultant’s obligation herein shall be met not only with the commencement of the Initial Term, but annually as well for duration of the Agreement. The City reserves the right to require complete, certified copies of all required insurance policies, at any time.

3.2.10.10 Reporting of Claims. Consultant shall report to the City, in addition to Consultant’s insurer, any and all insurance claims submitted by Consultant in connection with the Services under this Agreement.

3.2.10.11 Sub-Consultants. All sub-consultants shall comply with each and every insurance provision of this Section 3.2.10. Consultant shall therefore not allow any sub-consultant to commence work on any subcontract to perform any part of the Services until it has provided evidence satisfactory to the City that the sub-consultant has secured all insurance required under this Agreement.

3.2.10.12 Special Risk or Circumstances. The City reserves the right, in its sole and absolute discretion, to modify the requirements of this Section 3.2.10, including limits, based on any of the following: (A) the nature of the risk of the Services; (B) the prior experience of the insured; (C) the rating or other quality or characteristic of the insurer; (D) any special or unique coverage issues; and (E) any other special or unique circumstances.

3.2.11 Safety. Consultant shall execute and maintain its work and Services so as to avoid injury or damage to any person or property. In carrying out its Services, the Consultant shall at all times be in compliance with all applicable local, state and federal laws, rules and regulations, and shall exercise all necessary precautions for the safety of employees appropriate to the nature of the Services and the conditions under which the Services are to be performed.

3.2.12 Payment Bond. The California Department of Industrial Relations (“DIR”) has communicated to the City that there is a possibility that a payment bond may be required for certain services provided in connection with a public works project. Since such a requirement is currently contrary to the industry standard for the services provided by Consultant under this Agreement and since there is no direct legal authority for this position, the City is not requiring Consultant to provide a payment bond at this time. However, the City hereby reserves the right to require the Consultant to obtain and provide a payment bond for some or all of the project provided by the Consultant under this Agreement.

If the City determines that a payment bond is required for the project pursuant to Civil Code Section 9550 or any other applicable law, rule or regulation, Consultant shall execute and provide to City a payment bond in an amount required by the City and in a form provided or approved by the City. In the event a payment bond is required, the City agrees to compensate Consultant for all documented direct costs incurred by Consultant for such payment bond. The Parties shall memorialize the terms of such additional compensation and any other terms and conditions associated with the payment bond in an amendment to this Agreement.

3.2.13 Accounting Records. Consultant shall maintain complete and accurate records with respect to all costs and expenses incurred under this Agreement. All such records shall be clearly identifiable. Consultant shall allow a representative of City during normal business hours to examine, audit, and make transcripts or copies of such records and any other documents created pursuant to this Agreement. Consultant shall allow inspection of all work, data, documents, proceedings, and activities related to the Agreement for a period of three (3) years from the date of final payment under this Agreement.

DEAND\02000.50101\1401461.18 10

3.3.4 Extra Work. At any time during the Term of this Agreement, City may request that Consultant perform Extra Work. As used herein, “Extra Work” means any work which is determined by City to be necessary for the proper completion of the Project, but which the Parties did not reasonably anticipate would be necessary at the execution of this Agreement.

Consultant shall not perform, nor be compensated for, Extra Work without written authorization from City’s Representative.

3.3.5 Prevailing Wages. Consultant is aware of the requirements of Chapter 1 (beginning at Section 1720 et seq.) of Part 7 of Division 2 of the California Labor Code, as well as Title 8, Section 16000 et seq. of the California Code of Regulations (“Prevailing Wage Laws”), which require the payment of prevailing wage rates and the performance of other requirements on “public works” and “maintenance” projects. If the Services are being performed as part of an applicable “public works” or “maintenance” project, as defined by the Prevailing Wage Laws, and if the Total Compensation is $1,000 or more, Consultant and its subconsultants shall fully comply with the Prevailing Wage Laws for their employees and any others to whom such laws are applicable. Consultant and its subconsultants shall also be responsible for any and all violations and fines imposed on them pursuant to the Prevailing Wage Laws. Pursuant to SB 854, which amended the Prevailing Wage Laws, this Agreement would also be subject to compliance monitoring and enforcement by the California Department of Industrial Relations (“DIR”). Beginning April 1, 2015, no consultant or subconsultant may be awarded this Agreement unless registered with the DIR pursuant to Labor Code Section 1725.5. The City will report all necessary agreements to the DIR as required by the Prevailing Wage Laws. Consultant shall make copies of the prevailing rates of per diem wages for each craft, classification or type of worker needed to execute the Services available to interested parties upon request, and shall post copies at the Consultant’s principal place of business and at the Project site. It is most efficient for the Consultant to obtain a copy of the prevailing wages in effect at the commencement of this Agreement from the website of the Division of Labor Statistics and Research of the DIR located at www.dir.ca.gov/dlsr/. In the alternative, Consultant may obtain a copy of the prevailing wages from the City’s Representative. Consultant shall defend, indemnify and hold the City, its elected officials, officers, employees and agents free and harmless from any claim or liability arising out of any failure or alleged failure to comply with the Prevailing Wage Laws.

3.3.6 Apprenticeable Crafts. If the project is being performed as part of an applicable “public works” or “maintenance” project, as defined by the Prevailing Wage Laws, Consultant shall comply with the provisions of Section 1777.5 of the California Labor Code with respect to the employment of properly registered apprentices upon public works when Consultant employs workmen in an apprenticeable craft or trade. The primary responsibility for compliance with said section for all apprenticeable occupations shall be with Consultant.

3.4 Termination of Agreement.

3.4.1 Grounds for Termination. City may, by written notice to Consultant, terminate the whole or any part of this Agreement at any time and without cause by giving written notice to Consultant of such termination, and specifying the effective date thereof, at least seven (7) days before the effective date of such termination. Upon termination, Consultant shall be compensated only for those Services which have been adequately rendered to City, as well as any Docusign Envelope ID: 530CAE45-2B35-46CD-ADDE-625EDACE8837 Docusign Envelope ID: 1068EB3F-13BE-4305-92D1-180D94F40D35

Consultant shall have no right to retain or fail to provide to City any such documents pending resolution of the dispute. In addition, Consultant shall retain copies of all Documents & Data on file for a minimum of five (5) years following completion of the Project, and shall make copies available to City upon the payment of actual reasonable duplication costs. In addition, before destroying the Documents & Data following this retention period, Consultant shall make a reasonable effort to notify City and provide City with the opportunity to obtain the documents.

3.5.2 Subconsultants. Consultant shall require all subconsultants to agree in writing that City is granted a non-exclusive and perpetual license for any Documents & Data the subconsultant prepares under this Agreement.

Consultant shall be responsible and liable for its Documents & Data, pursuant to the terms of this Agreement, only with respect to the condition of the Documents & Data at the time they are provided to the City upon completion, suspension, abandonment or termination.

2.3.1) and completion of land net (Sub-Task 2.2.2) and topographic survey (Sub-Task 2.2.3) in autocad format.

Assumptions:
• Assumed up to $1,500 in ODC’s for agency fees for obtaining record documents.

Deliverables::
• Utility Introductory (A) Letters, Utility Matrix, Utility Base Map in AutoCAD format Sub-Task 2.4: Geotechnical Investigations
Preliminary Foundation Report
The Mark Thomas will prepare a Preliminary Foundation Report (PFR) for the retaining five walls in the project to provide preliminary geotechnical information to assist structural designers in the Type Selection process. This PFR will be prepared using the available subsurface data and the format will be in accordance with the current Caltrans Guidelines.

Geotechnical Investigations
Per Caltrans/AASHTO recommendations, a soil boring is required every 100 to 200 feet for retaining walls.

For pavement, a soil boring is proposed every 500 to 1,000 feet. Based on this, The Mark Thomas team’s geotechnical field investigations plan is presented in the table on the following page. Data obtained from some boreholes will be used for multiple design elements. For ground anchor walls, as-built borings from Ontario Avenue Undercrossing widening will be used; therefore, only one supplemental boring will be performed for each ground anchor wall. The boreholes will be excavated using a truck-mounted or trackmounted drilling rig equipped with 8-inch diameter hollow-stem augers. Asphalt concrete cold-patch will be used to replace asphalt that is removed by excavations, and quick-set cement will be used to replace concrete that is removed by excavations.

The RFP recommends performing pavement deflection testing to evaluate existing pavement conditions.

However, Falling Weight Deflectometer (FWD) testing is more expensive and is typically justified only on larger roadway projects. Given that the pavement improvement for this project is only approximately 2,200 feet in length, conducting FWD testing would not be cost-effective. Instead, pavement core samples will be collected at every boring location to determine existing pavement layer thicknesses, material composition, and general structural condition. Core extraction provides direct, physical data on the existing pavement section, which is sufficient for a project of this scale and for the design decisions anticipated. In addition, Dynamic Cone Penetrometer (DCP) testing will be performed in selected borings to evaluate the in-situ subgrade strength. Together, pavement core sampling and DCP testing will provide adequate and reliable information for pavement evaluation and design while maintaining cost efficiency for this short roadway segment.

The Mark Thomas team will prepare a boring location plan and this plan will be used to secure encroachment permits from Caltrans and City of Corona. Any other permits, if required, will be secured by others.

The Mark Thomas team field personnel will collect soil samples for laboratory testing, including bulk samples of near-surface soils and small disturbed and relatively undisturbed ring samples of deeper soils.

The small disturbed and relatively undisturbed soil samples will be collected using split-spoon samplers at a vertical interval of about 5 feet, alternating between the Standard Penetration Test (SPT) sampler and the Modified California Drive (MCD) sampler. Samples of subsurface soils will be logged during the field investigation, secured in their containers or collected in plastic bags, and transported to the our geotechnical consultant’s laboratory.

Laboratory Testing
Field logs of the boreholes will be reviewed to select representative soil samples for laboratory testing.

Various laboratory tests will be performed on soil samples to determine or derive their physical and engineering characteristics. Anticipated laboratory tests include: in-situ density and moisture content, grain size, direct shear, UU triaxial, consolidation, R-value, sand equivalent, maximum density and optimum moisture content, and soil corrosion tests. Laboratory tests will be conducted in general accordance with American Society for Testing and Materials (ASTM) standards or California Test methods.

Geotechnical Engineering Analyses
Results obtained from the field investigation and laboratory testing will be used to characterize subsurface soils and conditions and create idealized soil profiles for design purposes. The following analyses will be performed for the project:

Then the rest of the traffic analysis will be prepared in a single draft document submittal summarizing approach/methodology, traffic volumes, traffic analysis, safety and ISOAP.

Task 3.1.1 Traffic Analysis Approach and Methodology:

The Mark Thomas team will develop Methodologies and Assumptions Memorandum for the City and approve. This will describe the following:
• Study intersections;
• Baseline traffic data approach;
• Analysis procedures and assumptions;
• Traffic forecasting methodology and tools; and
• General approach to preparing the Traffic Operations Analysis Report (TOAR) The Mark Thomas team will also request all required collision data from Caltrans to perform required Intersection Safety and Operational Assessment Process (ISOAP) assessment.

Task 3.1.2 Data Collection and Existing Conditions Analysis:

This scope of services assumes analysis at up to the following study intersections:
• Ontario Avenue at California Avenue
• Ontario Avenue at U-Turn Location
• Ontario Avenue at Compton Avenue
• Ontario Avenue at I-15 Southbound Ramps
• Ontario Avenue at I-15 Northbound Ramps
• Ontario Avenue at State Street
Task 3.1.3 Traffic Volumes:

DEAND\02000.50101\1401461.18 26
the City and relevant pending and/or approved development projects to ensure that land use forecasts are appropriate.

The Mark Thomas team will develop the Design Year forecasts by applying the growth calculated from the base year and future year models to the existing traffic volumes. The Opening Year forecasts will be developed using interpolation between existing and Design Year volumes. Given that we anticipate this project would not add capacity to Ontario Avenue, the Mark Thomas team will develop one set of future volumes to represent No Build and Build alternative.

The AM and PM peak hour and daily volumes will be developed at the study intersections analysis locations during both Opening Year and Design Year conditions that will be used for other resource categories. To aid in this effort, we will collect daily vehicle classification counts at the following locations that can be used to assist in developing these volumes:
• Ontario Avenue west of I-15 Southbound Ramps
• Ontario Avenue undercrossing between Northbound and Southbound Ramps • Ontario Avenue east of I-15 Northbound Ramps
Task 3.1.4 Intersection Safety and Operational Assessment Process (ISOAP):

The Mark Thomas Tam will evaluate the project in accordance with Caltrans new Intersection Safety and Operational Assessment Process (ISOAP) process. This analysis will be performed at the I-15 ramp intersections with Ontario Avenue.

Task 3.1.5 Traffic Operations Analysis Report (TOAR):

The TOAR will provide summary and conduct operations analysis at study locations for study scenarios, as well as complete a safety review (looking at existing collision information).

Traffic Operations Analysis:

This scope of services assumes that the Mark Thomas team will conduct intersection capacity and freeway capacity assessment using the Synchro SimTraffic software intersection analysis. The Mark Thomas team will conduct the AM and PM peak hour LOS analysis at the study intersections a during the following scenarios:

Task 3.1.6 Vehicle Miles of Travel (VMT):

With SB-743, CEQA must now evaluate VMT as the impact metric associated with transportation. It is expected that the purpose and need statement will identify this as a gap closure project with turn lane extensions that do not add capacity to the interchange, and would therefore not result in a significant transportation impact related to VMT. The Mark Thomas team will approach this project assuming the project can screen from VMT as a project types not likely to lead to a measurable and/or substantial increase in vehicle travel. Key deliverables for this are:
• Induced Travel Study Methodology Memorandum – This will document and describe how the VMT assessment will be completed including the methodology employed for the effort. • VMT Screening Memorandum – This will formalize the project’s approach to screening and justify the project’s anticipated less-than-significant transportation impact on VMT.

Assumptions:
• The scope assumes one project build alternative (plus the no-build alternative) will be identified and carried through full evaluation for all Caltrans deliverables. • The scope assumes the collection of traffic counts at all six study intersections during the AM and PM peak periods (6-9 AM, 4-7 PM). Additionally, the traffic counts will include vehicle classification counts and pedestrian/bicycle counts for incorporation into the air quality and noise environmental assessments.
• This scope assumes that delay and level of service will be reported at all intersections. Queuing estimates will be provided for movements along Ontario Avenue and at all off-ramps. • The scope assumes that we will submit two rounds of review for the TOAR and VMT Memorandums:
a draft document submitted to Caltrans and a final document that responds to Caltrans comments.

Deliverables:
• Traffic Operations Analysis Report in PDF format
• Induced Travel Study Methodology Memorandum in PDF format • Vehicle Miles of Travel (VMT) Screening Memorandum in PDF format Task 3.2 Preliminary Environmental Study
The environmental process begins with validating key design elements with the City, including roadway widening limits, retaining wall locations, right-of-way and temporary construction easements, drainage improvements, multimodal facilities, and signal modifications. As part of this early coordination, the Mark Thomas team will prepare the Caltrans Preliminary Environmental Study (PES) Form, which establishes the initial regulatory framework for the project and confirms Caltrans’ expectations regarding the NEPA class of action, required technical studies, and anticipated permitting needs. The PES will incorporate the refined project description and serve as the foundation for determining the appropriate CEQA and NEPA pathways.

During PES development, the Mark Thomas team will evaluate potential environmental risks—such as traffic operations, hazardous materials, and community impacts—using the technical studies prepared to date, and updated Geometric Approval Drawings (GAD’s). This early coordination ensures the environmental strategy remains tightly aligned with project objectives and that the City receives clear, Docusign Envelope ID: 530CAE45-2B35-46CD-ADDE-625EDACE8837 Docusign Envelope ID: 1068EB3F-13BE-4305-92D1-180D94F40D35

Task 3.3 NEPA / CEQA Technical Studies
The following technical studies will be prepared in support of the NEPA EA and the CEQA EIR. These studies will be developed in accordance with applicable Caltrans Standard Environmental Reference (SER) guidelines and other relevant regulatory standards.

Unless otherwise noted, each technical study is assumed to undergo one round of review by the City and two rounds of review by Caltrans District 8. Additional review cycles requested by Caltrans will require a formal amendment to the contract and adjustment to the project budget.

3.3.1 Air Quality, Greenhouse Gas Emissions, Climate Change Analysis, and Energy Analysis The Mark Thomas team, will prepare the air quality, greenhouse gas (GHG) emissions, Climate Change, and energy analyses in support of the NEPA EA and CEQA EIR. These analyses will address both build alternatives and the No Build Alternative, consistent with NEPA and CEQA requirements.

Air Quality Report:

The Mark Thomas team will prepare the Air Quality Report using the California Department of Transportation (Caltrans) Standard Environmental Reference (SER), including the current version of the Air Quality Report Annotated Outline. The Mark Thomas team will ensure that the Air Quality Report includes all written analysis currently required by Caltrans within the Regulatory Setting and Affected Environment sections of the Annotated Outline. The Mark Thomas team will also prepare the following technical analyses:
• Short-Term Effects (Construction Emissions): Construction activities emissions inventory will be calculated using an updated schedule and the latest version of the CAL-CET2021 model. • Long-Term Effects (Operational Emissions):
o Emissions analysis will be prepared. Emissions will be estimated using the current version of the EMFAC model.
o Prepare the carbon monoxide hot-spot analysis, particulate matter emissions analysis, and the nitrogen dioxide emissions analysis as needed.
o Mobile Source Air Toxics analysis will be prepared.
o Greenhouse gas (GHG) emissions will also be prepared.

To fulfill requirements related to Transportation Conformity, the Mark Thomas team will prepare the Transportation Air Quality Conformity Findings Checklist. The Checklist will document that the project is not exempt from Project-Level Conformity and therefore must complete a Particulate Matter Hot-Spot Analysis to be presented to the Transportation Conformity Working Group (TCWG) hosted by the Southern California Association of Governments. The Mark Thomas team will coordinate with the project team to prepare and present the Particulate Matter Hot-Spot Form to the TCWG. The presentation will include an overview of Docusign Envelope ID: 530CAE45-2B35-46CD-ADDE-625EDACE8837 Docusign Envelope ID: 1068EB3F-13BE-4305-92D1-180D94F40D35

the proposed project’s purpose and need, a discussion of the existing roadway volumes and traffic forecast data in the opening year and horizon year for the Build and No-Build Alternatives, and an evaluation of the Project of Air Quality Concern (POAQC) criteria.

Based on similar past experiences, the Mark Thomas team does not anticipate that the project will be designated as a POAQC. Accordingly, this scope of work does not include detailed particulate matter dispersion modeling pursuant to the U.S. Environmental Protection Agency Transportation Conformity guidelines. After public circulation of the Draft Environmental Document, the Mark Thomas team will prepare the required Air Quality Conformity Assessment (AQCA) to document the Transportation Conformity Working Group findings.

Climate Change Report:

The Mark Thomas team will prepare a Climate Change Report. The Mark Thomas team will ensure that the Climate Change Report includes all written analysis currently required by Caltrans within the Regulatory Setting and Affected Environment sections. The Mark Thomas team will also verify the following technical analyses:
• Short-Term Effects (Construction Emissions): The Mark Thomas team will calculate the construction activities emissions inventory using an updated schedule and the CAL-CET2021 model.
• Long-Term Effects (Operational Emissions):
o The mobile source emissions analysis was based on a vehicle miles traveled (VMT) evaluation of induced demand using the National Center for Sustainable Transportation Induced Travel Calculator and the Riverside County Transportation Model. This task was completed by the prior traffic consultant. The Mark Thomas team will coordinate any related updates needed to inform the GHG emissions analysis with the new traffic team. o The Mark Thomas team will update the emissions analysis if the analysis years are revised or revised traffic data is prepared for the project. Emissions will be estimated using the current version of the EMFAC model.
o Prepare a discussions of project consistency with GHG reduction strategies, including reduction plans. This includes statewide, regional, and local GHG emissions reduction plans along with Caltrans GHG reduction strategies.

Energy Analysis Report:

The Mark Thomas team will prepare an Energy Analysis Report. Using Caltrans guidance and the template provided within the SER, the Energy Analysis Report will determine if the project would result in the wasteful, inefficient, or unnecessary use of energy, or wasteful use of energy resources. The analysis will address both direct and indirect energy effects of the project following the methodologies described in the Energy Analysis Report Annotated Outline (published in September 2025). Regarding short-term energy consumption, construction-related effects on energy resources associated with most highway projects would be greatest during the site preparation and concrete paving phases because the excavation, handling, and transport of materials requires considerable amounts of equipment and truck fuels. Fuel use and electricity consumption will be estimated using CAL-CET in accordance with the guidance for a quantitative analysis provided within the Annotated Outline for capacity-increasing projects.

Regarding long-term energy consumption, transportation-related activities account for approximately half of all the petroleum products consumed in California, which makes the energy analysis an important Docusign Envelope ID: 530CAE45-2B35-46CD-ADDE-625EDACE8837 Docusign Envelope ID: 1068EB3F-13BE-4305-92D1-180D94F40D35

Riverside County); contact the NAHC for a Sacred Lands File Check and a list of Native American contacts; and conduct historic background research. Native American representatives recommended by the NAHC will be contacted to solicit information regarding potential concerns. An archaeological field survey will also be conducted to observe and record any visible archaeological resources or cultural material within the project APE. The archaeological field survey will be conducted within the Caltrans ROW only, and will record any historic and prehistoric cultural resources identified. The archaeological survey will be conducted by one The Mark Thomas team archaeologist in 15-meter intervals over all areas within the APE containing visible ground surface. It is assumed that a Native American monitor will not be required during the archaeological survey, due to the entirely developed landscape.

It is understood that five resources have been previously recorded within the APE, including four historicera street segments and one historic-era utility pole. It is assumed that under the Caltrans Section 106 PA (2024), Appendix 4, the historic-era roadway segments and utility pole will qualify as Property Type 1:

Minor, ubiquitous or fragmentary infrastructure elements, that do not warrant evaluation, and are exempt.

It is further assumed that the archaeological survey will be negative for any newly recorded resources. In the event that unevaluated, potentially significant cultural resources are identified within the APE, the preparation and implementation of an Extended Phase I (XPhI) plan/report, Phase II evaluation plan/report or Historical Resources Evaluation Report (HRER) may be required and can be provided under augment.

Assumptions:
• The preparation of the HPSR, ASR, and APE map only will be required by Caltrans; No additional reports, evaluations or finding of effects documents will be required. • No more than one round of edits with Caltrans and/or the client on the delineation of the APE and no more than one round of edits with Caltrans and/or the client on the HPSR and ASR. • Our scope assumes an HRER will not need to be prepared. • Assume the HPSR Form Template will be sufficient for this undertaking and a narrative HPSR will not be required.
• Assume there are no archaeological historic properties or potential historic properties present within the APE, and the preparation and implementation of an Extended Phase I (XPhI) plan/report or Phase II evaluation plan/report, in the event that unevaluated, potentially significant archaeological sites are identified within the APE, is not included in this scope. • The Mark Thomas team will prepare a letter template to be placed on City or Caltrans letterhead for each of the Tribal contacts requested by Caltrans.
• Consultation request letters can be sent via email and do not need to be sent return receipt or certified mail. The Mark Thomas team will conduct follow-up phone calls or emails with each Tribal contact that does not respond within 30 days.
• Our scope assumes that no consultation with Caltrans Headquarters or the SHPO will be required.

Task 3.3.3 Biological Resources Technical Memorandum
The Mark Thomas team will conduct a desktop database review and a field survey of the project site and surrounding areas to document existing biological conditions. Based on these findings, the Mark Thomas team will prepare a biological resources technical report that we anticipate this to be a Natural Environment Study – Minimal Impacts which will summarize:
• Existing vegetation communities and habitat types
• Presence or potential for sensitive plant and wildlife species • Riparian areas or other jurisdictional features
• Potential project-related impacts on biological resources • Recommended avoidance, minimization, or mitigation measures, if applicable The memo will support both CEQA and NEPA documentation and will be prepared in accordance with applicable Caltrans SER guidance requirements.

Deliverables:
• Draft and Final Natural Environment Study – Minimal Impact in PDF format Task 3.3.4 Combined Paleontological Identification Report/Paleontological Evaluation Report The Mark Thomas team will complete the paleontological reports. A qualified paleontologist from the Mark Thomas team will perform a paleontological study to evaluate the potential for fossils within the project area, both at the surface and in the subsurface. The paleontological study will consist of a records search, analysis of existing data, and field survey. All work will be completed in compliance with City of Corona and Caltrans guidelines, as well as standards established by the Society of Vertebrate Paleontology (SVP).

Records Searches:

The paleontologist will request a paleontological records search from the Western Science Center (WSC) in Hemet, CA. The records search will identify known paleontological localities within the project area and a 1-mile buffer.

Analysis of Existing Data:

The paleontologist will conduct an analysis of existing data, which includes reviews of geologic mapping, published paleontological literature, previously completed paleontological assessment reports in the area, and available online databases, such as the Paleobiology Database. Paleontological sensitivity rankings will be assigned to each geologic unit identified within the project area. The project area and a 0.5-mile buffer will be mapped onto the highest resolution geologic maps available and overlain with a paleontological sensitivity layer for ease of reference.

Paleontological Field Survey
An initial review of available geologic maps indicates that the surface of the project is in part underlain by Pleistocene-age older alluvial deposits, which are typically considered to have a high sensitivity for paleontological resources using Caltrans sensitivity criteria. Therefore, a paleontological field survey is recommended to verify the geologic mapping, identify the existing level of disturbance within the project footprint, and document any fossils observed at the surface within the project area. Any identified fossils will be documented in detail and reported to the City of Corona and Caltrans. No fossils will be collected during the survey; however, recommendations on the treatment of the fossils (e.g., preconstruction collection or sampling) will be provided.

Paleontological Identification Report/Paleontological Evaluation Report (PIR/PER):

The results of the records search, analysis of existing data, and field survey will be used to assign paleontological sensitivities to the geologic units within the project area using the Caltrans tri-partite Docusign Envelope ID: 530CAE45-2B35-46CD-ADDE-625EDACE8837 Docusign Envelope ID: 1068EB3F-13BE-4305-92D1-180D94F40D35

A combined Paleontological Identification Report/Paleontological Evaluation Report (PIR/PER) will be prepared to convey the methods and results of the study. The PIR/PER will also include a description of the proposed project, project footprint, proposed excavations, and geological and paleontological context of the project area, and a discussion of the potential to encounter significant paleontological resources during grading and excavation in the project area. Based upon the projections of the potential to encounter significant fossils, the PIR/PER will state the potential impact of the project upon paleontological resources and will provide detailed recommendations for further paleontological tasks to reduce identified adverse impacts/effects, if necessary.

Assumptions:
• The paleontological records search fee at the WSC will not exceed $200. • The paleontological field visit will be completed by one paleontologist in one 8-hour day, including mobilization/demobilization.
• No fossils will be observed or collected during the field survey. • Changes in scope may require a change order.
• One round of comments on draft reports by the client prior to submission to the lead agency. • One round of comments on the draft PIR/PER and PMP by the lead agency. • Changes in scope may require a change order.

e. Authorize the City Manager, or his designee, to issue a purchase order to AD Improvements, Inc., in the amount of $682,189.

BACKGROUND & HISTORY:

The revitalization of the North Mall, in the heart of the downtown, is one of the catalytic projects in the Downtown Revitalization Plan. The site, located at 6th and Main, has long been underutilized. Over time, the City has acquired nearly all of the properties within the North Mall with the intent to redevelop the site as a mixed-use project.

Part of the redevelopment process is to prepare the site ready for development, which includes demolishing the City owned buildings that are no longer in use. On October 1, 2025, the City completed the first phase of the North Mall Demolition Project. Phase 2 of the demolition project consists of the demolition and disposal of three (3) buildings, consisting of thirteen (13) commercial units. Demolition activities include, but are not limited to, utility disconnection/removals, abatement of hazardous materials, teardown of existing structures, material removal, and fill and compaction to clear the site and leave the existing pad flush to surrounding asphalt/ grade surface elevations.

This staff report asks the City Council to authorize the purchase of 13 new compressed natural gas (CNG) buses to serve the Dial-A-Ride program for $2,987,394 using State and Federal Transit Administration funds.

RECOMMENDED ACTION:

That the City Council:
a. Authorize the purchase of thirteen (13) Startrans Senator Class C Ford compressed natural gas buses from Model 1 Commercial Vehicles in the amount of $2,987,394.
b. Authorize the City Manager, or his designee, to issue a purchase order to Model 1 Commercial Vehicles in the amount of $2,987,394

Page 317 of 707 ends

e. Make a determination under Corona Municipal Code Section 3.08.125(B) that competitive bidding has been satisfied based upon the reasons provided in the “Basis for Determination of Competitive Bidding” section of this report.

BACKGROUND & HISTORY:

The City of Corona Transit Service (CCTS) operates its transit program through the DialA-Ride (DAR) and Corona Cruiser fixed-route service. The DAR service is comprised of specialized demand response and Americans with Disability Act (ADA)-complementary paratransit service. This service provides curb-to-curb transportation to qualified individuals, seniors 60 and older, and persons with disabilities, while door-to-door service is available to those certified under the ADA program.

In May 2017, City Council authorized the purchase of eleven (11) Class C Ford compressed natural gas (CNG) buses for the City’s Dial-A-Ride program. These eleven (11) buses were in addition to two (2) similar vehicles purchased in 2012 to complete the DAR program’s thirteen-vehicle fleet. The current Dial-A-Ride fleet has exceeded the Federal Transit Administration (FTA) minimum useful service life of five years or 150,000 miles and continues to experience increasing maintenance demands and operational constraints
Therefore, staff recommends the purchase of thirteen (13) replacement buses through the California Association for Coordinated Transportation/Morongo Basin Transit Authority Purchasing Cooperative (CalACT), as was done for the 2017 vehicle procurement. The Cooperative was developed in accordance with the Local Government Purchasing Schedule, as defined by 49 Code of Federal Regulations (CFR) §18.36, wherein the FTA extends to states and local governments the authority to make arrangements with multiple vendors to provide options for goods or services at established prices. Through the Cooperative, bus manufacturers and distributors submitted sealed bids based on the potential for state-wide bus procurement. As such, the City can leverage the purchasing potential of the Cooperative to secure competitive pricing and as allowed under the Corona Municipal Code 3.08.140 ANALYSIS:

On August 6, 2025, the City Council awarded a contract to Michael Baker International, Inc. (MBI) to provide consulting services for Transit Technical Assistance in response to RFP NO. 25-030AT. MBI’s core project tasks include transit planning and routing, bus stop upgrades, fleet procurement, deployment of an Intelligent Transportation System, and deployment of zero-emission bus technologies.

In September 2025, MBI began researching potential manufacturers and vehicle models available from the Cooperative that are comparable to and could replace the existing fleet.

After reviewing various models available through the CalACT, it was determined that five (5) vehicles met the City’s base requirement. Research was conducted that considered the following factors: Altoona Testing Results for federal vehicle requirements and standards, warranties, floorplans, and available vehicle specifications. Of the available

Page 318 of 707 ends

five Class C Cutaway ADA CNG vehicle options, two models had poor Altoona Testing Results and were excluded from further consideration. The three remaining vehicle models were the Starcraft Allstar, the Startrans Senator, and the Glaval Universal. On November 5, 2025, and December 11, 2025, CCTS staff met to discuss required and desired vehicle specifications and features to prepare for coordination with the vendors.

The Starcraft Allstar and the Startran Senator are available through Model 1 and the Glalval Universal is available through A-Z Bus Sales.

MBI used the decisions at these meetings to develop an Independent Cost Estimate, as required by the FTA and the California Department of Transportation (Caltrans) Division of Rail & Mass Transportation. The purpose of the Independent Cost Estimate is to establish a benchmark for evaluating price reasonableness in vehicle procurement prior to obtaining vendor quotes. Considering required and desired vehicle specifications and features, staff anticipated a fair and reasonable price range for this procurement effort to be from $220,000 to $250,000 per vehicle.

In November 2025, staff also reached out to peer agencies to obtain feedback on both the prospective vendors and the vehicle manufacturers and models. The feedback on vendor performance was incorporated in the scoring matrix presented below.

After ongoing coordination with two vendors to establish required specifications and design vehicle floorplans for the three different vehicle models, CCTS requested formal quotes on January 23, 2026. Model 1 Commercial Vehicles (Model 1) provided quotes for the Starcraft Allstar and Startrans Senator, and A-Z Bus Sales, Inc. (A-Z) provided a quote for the Glaval Universal. All three models were priced using the same chassis, drivetrain, CNG conversion, and floorplan, as well as similar required and optional features such as suspension, fire suppression, wheelchair lift, surveillance, air conditioning, seating, and signage. The eleven (11) buses purchased in 2017 were equipped with the same or similar features.

Using a weighted scoring matrix, MBI evaluated the three vehicle models and the associated quotes based on seven criteria. The scoring was completed using a scale of one through three, with three being the most competitive and one being the least competitive. The results of the scoring, showing all weighted criteria, are provided in the table below. See Exhibit 1 for the full quote analysis matrix.

Based on the above methodology, the Startrans Senator received the highest total score.

The Senator’s per vehicle cost of $229,800 also within the price range identified in the Independent Cost Estimate.

City staff reviewed all documentation provided by MBI and are in concurrence with MBI’s recommendation. The Startrans Senator is an ADA-compliant transit bus built on a Ford E450 chassis and powered by compressed natural gas (CNG). The vehicle has a service life of five years or an accumulation of at least 150,000 miles. The Senator bus can accommodate 18 seated passengers, or 16 seated passengers with two passengers in wheelchairs. These buses are equipped with a rear wheelchair lift with a 1000-pound capacity, roof-mounted air-conditioning, vinyl upholstery and seat belts on every seat, destination signs and a stop request system, a video surveillance system, and an onboard fire suppression and methane detection system.

The cost for a Senator bus is $229,800 and the estimated cost for thirteen (13) buses is $2,987,394. Staff recommends that City Council authorize the purchase of the thirteen (13) Startrans Senator buses from Model 1 Commercial Vehicles. Upon approval by City Council, staff will request a letter of assignment from the Cooperative assigning the City of Corona thirteen (13) buses for the Startrans Senator bus to be purchased from Model 1 Commercial Vehicles.

Following City Council authorization, vehicle procurement is anticipated to take approximately 8 to 12 months for manufacturing and delivery. Upon delivery, an additional 3 to 6 months will be required to complete vehicle acceptance, inspections, grant compliance activities, and City‑ specific modifications prior to placing the buses in service.

BASIS FOR DETERMINATION OF COMPETITIVE BIDDING:

The Public Works Department is requesting to utilize the CalACT Purchasing Cooperative (Cooperative) to purchase equipment for this project pursuant to Corona Municipal Code (CMC) Section 3.08.125(B), based upon competitive bidding already being completed. “When the purchasing agent and authorized contracting party, with the approval of the City Manager, determines that:
(1) A competitive bid procedure has been conducted by another public agency, including, but not limited to, another local agency, the state, through the California Multiple Award Schedule (CMAS), the federal government, through the General Services Administration (GSA), the U.S. Communities Government Purchasing Alliance, or the Western States

Page 320 of 707 ends

Contracting Alliance (WSCA); and (2) The price to the city is equal to or better than the price to that public agency.”
FINANCIAL IMPACT:

Funding for the recommended actions is available in the Comprehensive Operations Analysis (COA) Replacement of Buses, Operating and Maintenance Project No. 76580 within Transit Service Fund 577. The purchase of buses is entirely grant funded. With the recommended action, funding for this procurement is available as follows:

Funding Source Estimated Amount
Federal Section 5307 $2,368,546
Federal Section 5339 $267,241
State Transit Assistance $636,600
State of Good Repair $102,399
Total Funding Sources $3,374,786
The total cost of the thirteen (13) buses is $2,987,393.73, leaving $387,392.27 in the Operating and Maintenance Project budget for the following additional costs related to bus procurement:

1. Change orders (10% of the contract) to include new vehicle wrap/decaling encompassing the city’s new branding.

2. Third-party in-plant bus inspection to include compliance audit, pre-delivery testing, and post-delivery inspection/verification services.

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 merely authorizes the purchase of thirteen (13) buses for the DAR fleet, and there is no possibility that approving this project will have a significant effect on the environment.

Therefore, no environmental analysis is required.

*Altoona testing results for all three vehicle options were reviewed specifically for the CNG model of the vehicle, except for the shakedown test. A shakedown test was not performed for the CNG version of the Starcraft Allstar, but it was performed on the gasoline version of the vehicle. In the absence of a result for the CNG version of Starcraft Allstar, the shakedown test result for the gasoline version of the vehicle was used instead for the purpose of this analysis. All three vehicles had similar water penetration issues identified in the shakedown test, which ultimately did not impact the overall Altoona test result score. In addition, all three vehicles are manufactured by Forest River, which has implemented improvements to address water penetration issues identified in the Altoona testing reports, such as improved weather seals and enhanced caulking procedures.

REQUEST FOR CITY COUNCIL ACTION
SUBJECT:

RESOLUTIONS INITIATING PROCEEDINGS TO LEVY AND COLLECT
ASSESSMENTS FOR FISCAL YEAR 2027 FOR LIGHTING MAINTENANCE DISTRICTS NO. 84-1 AND 2003-1, APPOINTING ENGINEER OF RECORD, AND ORDERING THE PREPARATION OF ENGINEER’S REPORTS
EXECUTIVE SUMMARY:

This staff report asks the City Council to consider staff’s recommendation to appoint Spicer Consulting Group, LLC to prepare the Engineer's Report necessary to levy and collect special assessments for Fiscal Year (FY) 2027 for Lighting Maintenance Districts No. 84-1 and 2003-1. Lighting Maintenance Districts No. 84-1 and 2003-1 were established in 1983 and 2003 respectively, in accordance with the provisions of the Landscaping and Lighting Act of 1972 to provide lighting maintenance and operating services for the public street lighting, traffic signals, and appurtenant facilities within the districts’ boundaries. The State of California Street and Highways Code Section 22500 require an annual review of the assessments levied by the special districts formed under the Landscape and Lighting Act of 1972.

RECOMMENDED ACTION:

That the City Council:
a. Adopt Resolution No. 2026-017, initiating proceedings to levy and collect assessments for Fiscal Year 2027 for Lighting Maintenance District No. 84-1

Page 323 of 707 ends

pursuant to the Landscaping and Lighting Act of 1972, appointing Engineer of Record, and ordering preparation of an Engineer’s Report. b. Adopt Resolution No. 2026-018, initiating proceedings to levy and collect assessments for Fiscal Year 2027 for Lighting Maintenance District No. 2003-1 pursuant to the Landscaping and Lighting Act of 1972, appointing Engineer of Record, and ordering preparation of an Engineer’s Report.

BACKGROUND & HISTORY:

Lighting Maintenance Districts Nos. 84-1 (LMD 84-1) and 2003-1 (LMD 2003-1) were established in 1983 and 2003, respectively, in accordance with the provisions of the Landscape and Lighting Act of 1972 (the 1972 Act). These districts provide lighting maintenance and operating services for the public street lighting, traffic signals, and appurtenant facilities within the district’s boundaries.

The benefit area of LMD 84-1 covers all of the original City boundaries in 1983 and annexation areas northwest of the City, as shown on Exhibit 1. The original boundary of LMD 2003-1 included the Corona Crossings and Dos Lagos developments. Since its formation, five developments have been annexed into LMD 2003-1. The current boundary of LMD 2003-1 is shown in Exhibit 2.

The State of California Street and Highways Code Section 22500 require an annual review of the assessments levied by the special districts formed under the 1972 Act. An Engineer's Report must be prepared to levy and collect special assessments within the districts, which provide details on the improvements maintained and the estimated budgets for each district.

ANALYSIS:

Staff recommend that the City retain the services of Spicer Consulting Group, LLC to prepare the Engineer's Reports necessary to levy and collect special assessments for FY 2027 for the above districts. The consultant has extensive experience in assessment district financing and administration and was selected as the City’s special tax consulting service provider through a competitive process in January 2023.

The attached resolutions initiate the proceedings pursuant to the 1972 Act to levy and collect annual assessments within each district for the maintenance, servicing, and operation of public streetlights, traffic signals, and other improvements within each district's boundaries. The resolutions also appoint Spicer Consulting Group, LLC as Engineer of Record to prepare the Engineer's Reports for each district for FY 2027.

FINANCIAL IMPACT:

The proposed annual fees of $28,080 for LMD 84-1 and $4,585 for LMD 2003-1 from Spicer Consulting Group, LLC, are for preparing the Fiscal Year 2027 Engineer's Reports, calculating special assessments, submitting the annual levy, and other administrative

Page 324 of 707 ends

tasks. The special assessment collected within each district will pay the cost and is included in the district's current budget.

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 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 sets the special taxes to be levied and collected within the Districts for Fiscal Year 2027, and there is no possibility that adopting the resolution will have a significant effect on the environment. Therefore, no environmental analysis is required.
