Agenda Item #: 6.20
Meeting Date: June 16, 2026
Given the scope of services required to support Public Works operations and transportation-related projects throughout the City, it is beneficial to maintain consultants with specialized technical expertise and the ability to respond efficiently to a broad range of transportation engineering, planning, ITS, signal operations, and development review assignments. Maintaining a diversified consultant structure will allow the City to effectively address ongoing operational needs, support capital improvement projects, and respond to emerging transportation-related issues in a timely manner. Additionally, retaining three (3) consultants enables the City to efficiently solicit the required three (3) quotes per the City’s Purchasing Ordinance prior to awarding work for certain public projects.

The scope of services to be provided may include:
• Geometric and Traffic Signal Design
• Environmental and Traffic Impact Analysis Report Preparation and Review • Conduct Studies and Report Preparation
• Traffic Management System Support
• Signal Timing
• Adaptive Traffic Control System (ATCS) Support
• Transportation System Planning
• Traffic Signal Operation and Coordination Studies
• Congestion Management Program (CMP) Data Preparation
• Project Management and Construction Support
• Public Meetings
• Intelligent Transportation Systems (ITS) Design
• Traffic Data Collection
• Freeway/Regional Traffic Modeling Services
• General Plan Preparation & Review Services
• Funding and Grant Support Services, and
• Other related services as requested by the City, which pertain to development and capital projects.

ANALYSIS:

On February 24, 2026, the City issued a Request for Proposals (RFP) inviting qualified consultants to submit proposals for traffic and transportation engineering services on an as-needed basis. A total of fifteen (15) proposals were received on March 17, 2026, from the following consulting firms:

1. ADVANTEC Consulting Engineers, Inc.

2. AGA Engineers, Inc.

3. Bowman Consulting Group, Inc.

4. Fehr and Peers

5. General Technologies and Solutions (GTS)

11. Linscott Law & Greenspan, Engineers

12. Minagar & Associates, Inc.

13. RKA Consulting Group

14. TJKM Transportation Consultants, and

15. Transtech Engineers, Inc.

City staff independently reviewed and evaluated each proposal based on the evaluation criteria identified in the RFP using the following evaluation criteria:

Page 343 of 655 ends

Agenda Item #: 6.20
Meeting Date: June 16, 2026
• Staff Qualifications
• Firms Qualifications
• Approach/Methodology
• Level of Effort (Staffing commitment and time allocation) • Ability to meet the City’s schedule and expectations
• Relevant References (Record of performance)
• Firm’s comments on the consulting service agreement
The Public Works staff evaluation panel unanimously recommends entering into three (3) year agreements for on-call traffic and transportation engineering services with Fehr & Peers, Iteris, Inc., and ADVANTEC Consulting Engineers, Inc., with the option to extend the agreements for one (1) additional two (2) year term upon mutual consent of both parties. Any proposed extension would be presented to the City Council for review and consideration prior to approval.

Each of these consultants has previously worked for the City, successfully delivering projects and services. The firms also possess broad experience with other municipalities and agencies, bringing a diverse knowledge base in local and regional municipal work.

Principal-level, Associate-level, and operational support staff are the personnel classifications most commonly used for the transportation engineering services that the City of Diamond Bar typically requires. Based on the fee proposals submitted by the fifteen (15) responding consultants, the hourly billing rates generally ranged from approximately $218/hour to $460/hour for Principal-level staff and from approximately $120/hour to $290/hour for Associate and operational support staff.

Staff anticipates that the majority of routine on-call assignments will primarily involve Project Managers, Senior Engineers, Associate Engineers, and operational support staff. Staff determined that Fehr & Peers, Iteris, Inc., and ADVANTEC Consulting Engineers, Inc. provide an appropriate balance of specialized expertise, operational support capabilities, responsiveness, and overall value for the City’s anticipated transportation engineering service needs.

Consultant Principal (hourly) Associate/Field Support (Hourly) Fehr and Peers $265 - $460 $215 - $290
Iteris, Inc. $258 - $464 $139 - $189
ADVANTEC $410 $145 - $160
Fehr & Peers (Attachment 1) is currently under contract with the city for on-call traffic and transportation engineering services and has provided valuable support for transportation planning and traffic engineering assignments, including support services related to the SR-60/57 Confluence Project PS&E, regional traffic analysis, and transportation planning support efforts. Fehr & Peers provides specialized expertise in transportation planning, CEQA-related transportation studies, and Vehicle Miles Traveled (VMT) analysis services that support development review and regional transportation coordination efforts. Continued use of Fehr & Peers is necessary to maintain continuity, support ongoing coordination and technical analysis, and ensure consistent and timely completion of these active transportation-related projects and planning efforts.

Iteris, Inc. (Attachment 2) is currently under contract with the City for on-call traffic and transportation engineering services and has consistently provided responsive and technically sound support services, including maintaining and optimizing the citywide traffic signal timing coordination and synchronization system, traffic signal communication integration and communication troubleshooting, and ongoing support for the City’s Traffic Management System (TMS) and Adaptive Traffic Control System (ATCS). Due to the specialized nature of these systems and Iteris’ existing familiarity with the city’s traffic signal infrastructure and communications network, continued use of Iteris is necessary to maintain continuity, support ongoing system operations and adaptive signal timing efforts, minimize transition risks, and ensure efficient completion of active ITS-related projects and coordination efforts.

Agenda Item #: 6.20
Meeting Date: June 16, 2026
ADVANTEC Consulting Engineers, Inc. (ADVANTEC) (Attachment 3) demonstrated strong qualifications and extensive experience in providing on-call traffic and transportation engineering services to public agencies throughout Southern California, including prior support services for the City of Diamond Bar. ADVANTEC provides responsive and cost-effective local support for day-to-day traffic engineering, operational reviews, field coordination, traffic studies, plan checking, and design support services. The firm’s local office proximity to City Hall allows for efficient coordination with City staff, rapid response to operational and field-related issues, and timely support for ongoing transportation-related assignments.

As part of the evaluation process, staff contacted the Cities of Anaheim, Upland, and Corona to obtain references regarding ADVANTEC’s performance on similar municipal assignments. Feedback from all three agencies was positive and highlighted the firm's responsiveness, technical competence, professionalism, and ability to deliver quality services in a timely manner. Staff determined that ADVANTEC’s combination of local presence, municipal traffic engineering experience, operational support capabilities, technical expertise, positive client references, and competitive fee structure provides strong value to the City for routine on-call transportation engineering services requiring responsiveness, coordination, and cost-effective service delivery.

Compensation for these traffic and transportation engineering services will be billed in accordance with the appropriate classification of service provided pursuant to each consultant’s approved fee schedule.

CEQA/NEPA/
Transportation Studies
We have over 40 years of experience in preparing
general plans and transportation planning studies
across California, including studies in support of
the project approval/environmental documents
for Caltrans projects. In addition, we provide peer
revieø services for traffic stìdies for Caltrans
projects on behalf of other local agencies and have
provided peer review services for Diamond Bar
since 2006, including support for the SR-57/60
Confluence Project.

Our focus will be providing sound transportation
system planning; a detailed understanding of the
CitþŅs traffic circìlation needsĨ ìilding consensìs
between various stakeholders; and ensuring that
the technical documents meet CEQA and NEPA
requirements and can easily be understood by
decision makers, grant reviewers, and the public.

Since the adoption of Senate Bill 743 (SB 743), Fehr
š Peers °as een at t°e forefront of sìpporting
cities throughout California in development,
adoptionĦ and application of sDT Çetrics and
thresholds. We are currently assisting a multitude
of cities, counties, and MPOs, both large and
small, to ensure land use and transportation
projects are compliant with adopted policies
and guidelines. We will assist Diamond Bar in
reviewing transportation studies for development
and transportation projects to meet California
Environmental Quality Act (CEQA) and SB 743
requirements.

sìc° as freeøaþ and arterial sþsteÇsĦ traffic signal
operations, intelligent transportation systems, and
interface between autos and other travel modes
(e.g., light rail, bus, rapid transit, heavy vehicles,
cycling, and walking).

We are very familiar with the Intersection Safety
and Operational Assessment Process (ISOAP)
required by Caltrans and have prepared multiple
ISOAP documents for various local agencies via
a data-driven, performance-based framework
incorporating the Safe System Approach to
screen intersection strategies and identify optimal
solutions for new or improved intersections,
typically at the ramp intersections.

Speed Studies/Safety
Assessments
&e°r š Peers partnered øit° /TEĦ t°e sision ero
Network, and Leidos to work with the Federal
-ig°øaþ dÇinistration Office of Safetþ to
develop educational materials (a brochure, a
training course, and a video) launching FHWA’s
Safe System approach. The team also authored
the national guidance document on how to pivot
Strategic Highway Safety Plans and Highway Safety
Improvement Programs to be consistent with the

We have extensive experience in supporting
jurisdictions throughout California as they develop
and implement Local Roadway Safety Plans, SS4A
fìnded sision ero Safetþ ction PlansĦ Safe
Routes to School Plans, Active Transportation
Plans, and HSIP projects. Most recently, we have
been pioneering work related to the systemic
approach to safety through Caltrans’ Systemic
Safety Analysis Report Program. We created the
award-winning Pedestrian Safety Assessment
program now in use throughout California and
teach multi-modal safety and complete streets
courses at the regional, state and national level,
including most recently for Caltrans and FHWA.
&e°r š Peers is cìrrentlþ øor¾ing øit° &-tĦ
advising the agency on how best to integrate Safe
System principles into their existing programs,
such as Strategic Highway Safety Plans (SHSP),
the Highway Safety Improvement Program (HSIP),
and Local Roadway Safety Plans (LRSP). We
will leverage our insight and expertise in safety
principles to assist the City of Diamond Bar in
safety-related assessments.

We have developed internal tooling for datadriven safety analysis to support jurisdictions in leveraging safety-oriented legislation such
as ĕĔ and applþing conteýt specific speed
management strategies to better align speedsetting practices with goals to improve safety.

Transportation
System Planning
&e°r š Peers °as een a recogniąed leader
in innovative transportation planning with an
emphasis on integrating land use decisions with
transportation investments. Because Diamond
Bar is surrounded by two major regional freeways,
SR-57 and SR-60, transportation system planning
requires close coordination with Caltrans, Metro,
and adjacent cities, and is important for meeting
the City’s mobility goals. Since 2006, we have
assisted Diamond Bar on a variety of tasks related
to the SR-57/60 Confluence Project, including peer
revieø of traffic stìdiesĲenvironÇental docìÇentsĲ
design plans, preparation of studies and plans for
improvement strategies, coordination with Metro/
Caltrans/other stakeholders, and more. We will
continue working closely with City staff in a similar
role for the SR-57/60 Confluence Project.

We have extensive experience working with
Caltrans, from delivering planning/design projects
to providing best practice training to Caltrans staff.

We have delivered over 150 highway planning and
design projects throughout the State of California
during the phases of Project Study Report –
Project Development Support (PSR-PDS), Project
Approval/Environmental Document (PA/ED), and
PlansĦ SpecificationsĦ and EstiÇates ĺPSšEĻĥ te
are also often asked to provide peer review of
transportation impact studies for highway corridor
and interchange projects and their compliance
with CEQA/NEPA on behalf of local agencies.

We have a long history of working with Caltrans
District 7 (D7) and have successfully delivered
various highway planning PSR/PA/ED/PSEs in Los
Angeles County. In addition to project delivery,
we have assisted Caltrans in developing the best
practice training in travel demand modeling and
traffic operations analþsis as øell as a °oø-to gìide
for Caltrans Local Development-Intergovernmental
Review (LD-IGR) that addresses the changes
to transportation impact analysis under SB 743,
including potential transportation safety impacts.

Our extensive experience working with Caltrans
will help the City to facilitate the transportation
projects to go through the approval and
implementation process.

Statewide Planning Efforts
California’s legislative requirements and statewide
planning efforts shift frequently. We pride
ourselves on staying up to date on the latest
industry trends and quickly adapting to prepare
specialized studies. Recently, statewide legislation
Assembly Bill 98 mandated that truck routes be
included in all General Plans. We have quickly
leveraged our existing national experience in
freight planning, truck routing, and truck parking
to assist our local clients in Southern California in
integrating the new requirements into their General
Plans.

COVER LETTER
March 17, 2026
Christian Malpica
Associate Engineer/Project Manager
City of Diamond Bar – Public Works Department
21810 Copley Drive
Diamond Bar, CA 91765
11477-141.26
RE: Proposal for Professional On-Call Traffic and Transportation Engineering Services The City of Diamond Bar continues to prioritize safety, reliable, and efficient transportation operations across its roadway network.

Maintaining this performance requires responsive engineering support, deep knowledge of the City’s communication and traffic systems, and the ability to quickly address operational challenges as they arise. Iteris has had the privilege of supporting the City in these efforts over the past several years, working closely with Public Works staff to maintain and improve traffic operations throughout the community.

Through this ongoing collaboration, our team has developed a detailed understanding of city’s traffic signal infrastructure, communications network, and traffic management systems. This institutional knowledge allows Iteris to respond quickly to the City’s needs, provide practical engineering solutions, and support City staff without the learning curve typically required by new consultants.

Iteris proposes Mr. Omid Modaghegh, MCSE, IMSA as Project Manager for this opportunity. Mr. Modaghegh has been the technical support and communicator with the city for the past several years – he has extensive experience supporting local agencies with traffic operations, signal timing, communications systems, and ITS infrastructure throughout Southern California. He has directly supported the City of Diamond Bar and is familiar with the City’s signal systems, adaptive operations, SCOOT and communications architecture. As Project Manager, Mr. Modaghegh will serve as the City’s primary point of contact and will oversee all task assignments to ensure responsive service, technical quality, and clear communication. In addition to Mr. Modaghegh, he will be supported by Mr. Bernard Li, EE, TE, PTOE with over 35-years of Transportation and Traffic Engineering experience will be the Principal-In-Charge and Quality Assurance and Quality Control (QA/QC) lead. Below is a list of Iteris’ distinct advantages:
• DIRECT FAMILIARITY WITH CITY’S TRAFFIC SYSTEMS AND COMMUNICATIONS INFRASTRUCTURE.

Iteris brings unmatched continuity and institutional knowledge of the City’s transportation environment. Our team is familiar with the City’s traffic signal network, ATMS environment, Siemens TACTICS platform, adaptive SCOOT operations, Siemens SEPAC 2070 controllers, Siemens Ruggedcom switches, Clary battery backup systems, Cohu CCTV cameras, and the TranSuite video control system. This familiarity allows Iteris to respond efficiently, troubleshoot issues faster, and support the City without the learning curve required by a new consultant. • DEPTH OF QUALIFIED MULTIDISCIPLINARY STAFF AND TECHNICAL EXPERTISE Iteris provides the City with a multidisciplinary team that includes experts in traffic engineering, traffic studies, signal timing, traffic signal design, ITS integration, communications systems, plan check, and construction support. Our staff includes licensed engineers, IMSA certified professionals, and personnel with Microsoft, Cisco, and related technical certifications. This depth allows Iteris to provide complete support across the full range of on call services through one coordinated team.

Project Understanding
The City of Diamond Bar is requesting a consultant team that can step in as needed to support the city staff across a broad range of transportation-related assignments. Work under this contract will range from traffic operations, transportation planning, plan review, signal design, field coordination to traffic management system support. Each task will require clear communication, sound engineering judgment, and the ability to adapt to the City’s priorities and schedule.

The City’s transportation system serves residential neighborhoods, commercial areas, schools, major arterial corridors, and regional travel connections. Supporting this network requires practical solutions that balance safety, mobility, and overall system operations.

Technical support should not only address immediate operational needs but also help the city maintain reliable performance and make informed decisions as transportation needs continue to evolve.

On call assignments can vary significantly in size and complexity, ranging from focused operational reviews to larger studies, design support, and implementation assistance. A successful team must be able to respond efficiently, define the issue quickly, and provide recommendations that are clear, actionable, and aligned with City objectives.

Coordination with City staff and other stakeholders will also be important to keep tasks moving and avoid delays. Iteris’ recent on-call support with the city for the past several years provides our team’s invaluable experience and understanding of City’s signal infrastructure, communications environment, operational needs and process. This experience and knowledge set us apart from other consulting firms by reducing ramp up time and allowing the team to provide effective support from the start of the contract.

Project Approach and Methodology
A responsive and well-defined task order process is essential to deliver high quality transportation engineering services. Our approach is centered on clear communication, timely response, technical accuracy, and practical implementation. The objective is to support the City with reliable engineering services that are aligned with task requirements, schedules, and operational priorities.

For each assignment, the Iteris project manager will coordinate with the City’s project manager to confirm the scope, schedule, review available information, and expected deliverables. This initial coordination helps define the level of effort, establish the task objectives, and confirm the appropriate technical approach before work begins.

Once a task order is authorized, the team will review available background information such as plans, traffic data, signal timing information, prior studies, and other relevant materials. When needed, field verification will also be performed to confirm existing conditions and identify issues affecting safety, traffic operations, or overall system performance.

Based on the nature of the assignment, the team will then perform the appropriate engineering analysis using established traffic engineering practices and professional judgment. Depending on the task, this work may include traffic operations review, safety evaluation, signal timing analysis, design development, or transportation planning assessment. The focus will remain on developing clear, practical, and implementable recommendations that support City objectives.

Scope of Services
The following sections describe the transportation engineering services that can be provided under this on call contract.

Assignments may range from focused technical support and brief reviews to more involved studies, design efforts, field coordination, and operational improvements. The level of effort for each task can be tailored to the City’s specific needs, schedule, and priorities.

This contract is intended to provide the City with responsive support across a broad range of transportation-related needs.

Depending on the assignment, work may include technical analysis, coordination with staff and stakeholders, review of available information, preparation of exhibits or memoranda, and follow up during implementation. Some task orders may be completed quickly, while others may require a broader level of review and coordination. In each case, the goal will be to provide practical, well organized, and dependable support that helps the city move work forward efficiently.

A. Traffic Engineering and Traffic Studies (Task Lead: Deepak Kaushik) Traffic engineering services will be a major part of this contract and may include both routine and more detailed technical evaluations. Some assignments may be tied to development review or environmental documentation, while others may focus on specific operational or safety concerns identified by City staff or the public. In each case, the work will focus on understanding existing conditions, identifying the issue clearly, and providing recommendations that are practical and supported by sound engineering judgment.

Services in this area may include:
• Review of traffic impact studies and traffic sections of environmental documents • Speed surveys and speed limit determinations
• School safety evaluations and citizen complaint investigations • Intersection level of service analysis and traffic control device evaluations • Evaluation of pedestrian and intersection safety improvements, including Leading Pedestrian Intervals, pedestrian scramble operations, and turn restriction treatments such as No Right Turn on Red • Vehicle Miles Traveled analysis, including project screening, technical review, mitigation evaluation, and support for CEQA compliance consistent with State and regional guidelines Depending on the assignment, findings may be documented through a technical memorandum, formal study, or focused summary prepared for City review.

B. Design, Plans Specifications and Estimates, and Plan Checking (Task Lead: Bowen Yang)
When assignments move into design, support may extend from early review of existing conditions through preparation of complete plans, specifications, and estimates. This may include geometric improvements, traffic signal design, signing and striping plans, multimodal improvements and related traffic control improvements. Available record drawings, field conditions, utility considerations, and operational needs will be reviewed at the outset of a project, therefore final design is aligned with City priorities and project requirements.

Plan checking will also be an important part of this contract, particularly for proposed development projects and traffic control plans related to encroachment permits. Reviews will focus on compliance with City standards, Caltrans requirements, the California MUTCD, operational impacts, safety, and constructability. Comments will be organized clearly so staff and applicants can resolve issues efficiently and keep the review process moving.
