PROJECT UNDERSTANDING
The City of Diamond Bar has initiated a comprehensive
three-year Pavement Design Program encompassing
residential, collector, and arterial street rehabilitation,
as well as ADA curb ramp improvements. This multi-
phase effort is intended to advance the City’s 2025
Pavement Management Program (PMP) Update, focusing
on long-term pavement preservation, ADA accessibility,
and cost-efficient capital programming. The City will also
utilize Community Development Block Grant (CDBG) funds
to upgrade ADA-compliant curb ramps within Areas 1, 6
and 7. CDBG funding will cover construction, while local
funds will support design services.
HR Green understands that the city seeks an experienced
civil engineering partner to deliver complete Plans,
Specifications, Estimates (PS&E) that align with PMP’s
data-driven recommendations. Our proposed services
will be structured to support the City’s objectives by
implementing:
Zone-based project scheduling that maximizes
construction efficiency and minimizes disruption.
Treatment selection strategies tailored to pavement
condition indices (PCI) and field-verified conditions; and
Design solutions that extend pavement life cycles and
optimize the use of available funding sources.
Through this program, HR Green will assist the city in
achieving its PMP goals to maintain streets in the “Good”
PCI category, reduce deferred maintenance, and preserve
the community’s infrastructure investment through sound
engineering and fiscal stewardship.
HR Green understands that the FY 25/26 design effort
represents a critical step in advancing the City’s long-term
pavement management strategy. The project will deliver
comprehensive PS&E packages that support a three-year
capital program focused on:
Extending pavement service life through proactive
maintenance, timely overlays, and data-driven treatment
selection.
Minimizing deferred maintenance and reconstruction
costs by preserving pavements above the critical PCI
threshold of 65.
Implementing accessible and ADA-compliant
infrastructure within designated Community
Development Block Grant (CDBG) areas; and
Coordinating with the City’s Complete Streets and
multimodal goals, ensuring arterial corridors such as
Grand Avenue and Diamond Bar Boulevard integrate
bicycle, pedestrians, and transit-friendly features.
By combining field-verified engineering data, geotechnical
evaluation, and zone-based design sequencing, HR Green
will help the City achieve measurable PCI improvements
while optimizing the use of RMRA, Measure M, and Gas
Tax funds. Our approach ensures that each project phase
not only meets technical requirements but also advances
the City’s broader objectives of infrastructure preservation,
safety, and fiscal responsibility.

POTENTIAL
CHALLENGE BRIEF DESCRIPTION HR GREEN SOLUTION
Variable Pavement
Conditions
Pavement sections may differ
from PMP assumptions due to
aging, patching, or prior repairs.
Conduct targeted field coring and detailed field
investigations to verify existing pavement structure;
adjust rehabilitation strategy (e.g., slurry vs. overlay
vs. FDR) accordingly.
Subgrade Instability
Unstable or moisture-sensitive
subgrades may cause premature
failure in reconstructed or
overlaid areas
Incorporate geotechnical verification and moisture-
density testing; consider subgrade stabilization or
full-depth reclamation where warranted
Drainage and Ponding Issues
Localized depressions or poor
cross slopes create ponding,
particularly at intersections and
low points.
Perform field survey and drainage analysis; regrade
gutters, adjust profiles, or replace cross gutters to
restore positive drainage.
Utility Conflicts
Utility vaults, meters, and
manholes may conflict with
pavement restoration or ramp
locations.
Identify critical utilities early; coordinate adjustments
with owners during preliminary design and integrate
utility relocations into PS&E.
Steep Grades / Limited Landing Space
Existing topography may preclude
ADA compliance within standard
ramp footprints.
Develop customized ramp geometries (e.g., directional
or parallel ramps), include localized pavement
reconstruction or extended landings to meet ADA
slopes.
Private Encroachments
Driveways, walls, planters, or
landscaping may extend into the
public ROW near ramp locations.
Conduct field review to identify conflicts; coordinate
with property owners; adjust ramp placement or
design to minimize disturbance while maintaining
compliance.
Maintaining Access to Schools and
Businesses
Work zones near schools, transit
stops, or businesses can create
access and safety concerns.
Schedule work during off-peak periods; maintain
pedestrian detours and signage; communicate
schedule changes through advance outreach.
Bikeway Integration
Along Arterials
Incorporating new or improved
bike lanes requires coordination
with existing striping and traffic
operations.
Evaluate corridor geometry and striping in accordance
with the City’s Complete Streets Policy; prepare
revised signing and striping plans with City review.
Public Concerns or
Complaints During
Construction
Construction activities can
generate noise, dust, or
temporary access issues.
Provide advance notification flyers and contact
information; respond promptly to resident inquiries
through City-coordinated communication.
Consistency Across
Multi-Year Phases
Deferred projects or future
phases must tie seamlessly to
current-year designs.
Maintain standardized design templates and drawing
details for continuity; document assumptions for
future incorporation into later contracts.
Bid Market Volatility Asphalt and material pricing may
fluctuate before construction.
Prepare bid alternates (e.g., conventional vs. rubberized
overlays); include escalation contingencies in estimates;
monitor Caltrans cost indexes and other local bid prices.
Through proactive planning and transparent communication, HR Green will mitigate these challenges before they
affect schedule or cost, ensuring durable pavement solutions and smooth delivery.

IMPLEMENTATION PLAN AND
RECOMMENDATIONS
HR Green will provide comprehensive civil engineering
design services to support the City of Diamond Bar’s FY
25–26 Pavement Rehabilitation Program (PMP) and ADA
Improvement Program. We will incorporate necessary data
and guidelines from the PMP with the city’s direction.
We understand the critical role this program plays in
maintaining the City’s 154 miles of roadway at a PCI of 78
or improving the PCI of 82, based on the city’s direction,,
implementing cost-effective rehabilitation strategies, and
enhancing ADA accessibility and mobility for all users.
Our approach is strategic, data-driven, and rooted in
decades of successful delivery for agencies across
Southern California. We specialize in combining preventive
maintenance design with targeted capital rehabilitation,
ensuring every dollar invested yields measurable pavement
life extension and reduced deferred maintenance costs.
Our preservation-first approach blends advanced
pavement evaluation, zone-based planning, and integrated
ADA/Complete Streets design.
Summary of HR Green Competitive Advantages:
Preservation-First, Risk-Based Strategy: HR
Green’s pavement program philosophy emphasizes
maximizing PCI and minimizing lifecycle costs by
applying the right treatment at the right time. Our
approach integrates risk-based construction method
evaluation, aligning preventive maintenance with
pavement condition thresholds, subgrade performance
data, and deterioration modeling to ensure long-term
network resilience.
Proven Municipal Delivery for Similar Program
Scopes: Our team has successfully delivered multi-
year pavement rehabilitation and ADA curb ramp
programs for peer agencies throughout Southern
California. This includes PS&E development, zone-based
implementation, and coordination with utilities and
Caltrans for arterial rehabilitation projects, mirroring the
scope and structure outlined in the Diamond Bar PMP.
Comprehensive QA/QC and Zone-Based Delivery
Model: HR Green’s QA/QC process is structured
to ensure constructability, budget adherence, and
on-schedule delivery. Our zone-based coordination
model minimizes traffic impacts, improves sequencing
for slurry seal and overlay operations, and provides field
validation through coring, drainage analysis, and ADA
curb ramp site verification.
Dedicated Municipal Team with Deep PMP
Experience: HR Green’s pavement program team
is composed of seasoned municipal engineers, GIS
analysts, and construction support staff who have
delivered similar PMP programs for multiple cities in
Los Angeles, Orange, and Riverside Counties. Our staff
has decades of experience in PMP implementation, ADA
ramp design, arterial rehabilitation, and capital project
delivery.
Flexible, Funding-Aware Program Implementation:
Our methodology is structured to leverage multiple
funding sources (e.g., RMRA, Measure M, Measure
R, Gas Tax, CDBG) and align project phasing with
available budget cycles. This allows the City to maintain
or improve PCI performance while controlling deferred
backlog, a key success factor identified in the PMP
update.
Complete Streets and ADA Integration: HR Green’s
design approach ensures all arterial projects incorporate
Complete Streets elements, ADA curb ramp upgrades,
and Caltrans compliance. This helps the city future-
proof its roadway network and position projects for
additional state or federal funding opportunities.
RISK-BASED CONSTRUCTION METHOD
EVALUATION
HR Green applies a structured, data-driven risk-based
evaluation framework to support the City of Diamond
Bar in selecting the most appropriate and cost-effective
construction methods for each rehabilitation segment.
Building on the City’s 2025 Pavement Management
Program (PMP) findings, which identify condition-based
PCI thresholds, life-cycle costs, and treatment triggers, we
will assess pavement treatment options by systematically
weighing technical performance, construction risk, cost
implications, and lifecycle value.
Our process begins with field verification and coring data
to validate pavement condition assumptions in the PMP
and confirm subsurface structure, drainage adequacy,
and soil stability. For each street segment, we will identify
key risk factors such as unstable subgrades, poor cross-
slopes, shallow utilities, or limited drainage grades that
could affect constructability or long-term performance.
Each potential rehabilitation method, slurry seal, micro-
Page 6

Streets Rehabilitation, and Residential Neighborhood ADA Curb Ramps Improvement Project
Z City of Diamond Bar
surfacing, cape seal, asphalt rubber hot-mix overlay,
grind-and-overlay, or full-depth reclamation, will then
be evaluated through a risk-versus-benefit matrix. For
example, segments exhibiting deep-seated distress or
poor subgrade support may warrant full-depth reclamation
with cement while stable corridors with moderate cracking
could receive cost-saving thin overlays or cape seals.
Finally, HR Green documents this analysis in a decision
matrix summary accompanying each PS&E package. This
ensures transparency in method selection and provides
the City with a defensible basis for construction method
choice, aligning with the City’s PMP goals to maintain a
“Good” PCI, minimize deferred maintenance, and optimize
long-term value of pavement investments.
APPROACH TO IDENTIFYING CURB RAMP
UPGRADES
HR Green applies a risk-based, field-driven approach
to identify and design ADA-compliant curb ramps that
balance accessibility, cost, and constructability. Each
candidate ramp is evaluated through detailed field reviews,
spot surveys, and GIS mapping to document grades, cross
slopes, drainage patterns, and adjacent conditions.
We focus on identifying site-specific constraints such as
steep grades, tight right-of-way, private encroachments
(e.g., driveways, walls, landscaping), and existing utilities
that can affect compliance. Where conflicts arise, HR
Green develops practical alternatives, directional or
parallel ramps, localized pavement reconstruction, or
minor grade adjustments, to achieve ADA compliance
while maintaining proper drainage and minimizing property
impacts.
Utility coordination is integral to our process. We identify
vaults, meters, hydrants and poles early and work with
utility owners to resolve conflicts before final design. Each
ramp is then assigned a constructability risk rating based
on slope correction, utility impact, and encroachment
severity, allowing the City to prioritize upgrades that
deliver the greatest accessibility benefit within available
funding. This structured approach ensures all ramps
are designed for long-term durability, compliance, and
community compatibility.
HR Green will evaluate existing ramps within each
identified area and recommend eight (8) locations per area
for installation or upgrade. The team will prepare complete
Plans, Specifications, and Estimates (PS&E) for these
improvements in full compliance with the Americans with
Disabilities Act (ADA), Caltrans Standard Plans, and the
Public Rights-of-Way Accessibility Guidelines (PROWAG).
APPROACH FOR IDENTIFYING AND
ENGAGING KEY STAKEHOLDERS
HR Green takes a proactive and collaborative approach
to stakeholder engagement to ensure design solutions
align with community expectations, City priorities, and
regulatory requirements. Early in the project, we work with
City staff to map all key stakeholders, including adjacent
residents and businesses, utility agencies, school districts,
transit providers, and regional partners such as Caltrans
and Los Angeles County Public Works.
We begin by identifying potential points of coordination
such as driveway access, school circulation, bus stops,
and business frontages within the project limits. Our
team then develops a focused communication plan that
uses mailers, door notices, GIS-based contact lists, and
targeted outreach meetings to keep stakeholders informed
throughout design and construction.
During design, we engage with City departments and
external agencies through regular coordination meetings
to review traffic control concepts, bike lane improvements,
curb ramp locations, and utility adjustments. For complex
locations, HR Green prepares visual exhibits to facilitate
consensus and document decisions.
This structured engagement process ensures that all
voices, City staff, residents, businesses, and partner
agencies, are heard early, conflicts are resolved efficiently,
and final PS&E packages reflect both technical excellence
and community support.
INNOVATIVE APPROACHES TO
IMPLEMENTING THESE SERVICES
HR Green leverages technology, data integration, and
proactive coordination to deliver innovative, efficient, and
resilient pavement and ADA improvement projects. Our
approach combines proven engineering practices with
modern tools that enhance accuracy, transparency, and
communication throughout design and construction.
Page 7
FY 25/26 CIVIL ENGINEERING DESIGN SERVICES FOR: Residential & Collector Streets Rehabilitation, Arterial
Streets Rehabilitation, and Residential Neighborhood ADA Curb Ramps Improvement Project
Z City of Diamond Bar
We utilize asset mapping and mobile field data collection
to align design efforts with the City’s Pavement
Management Program (PMP) database. During field
reviews, our teams use tablet-based apps to log pavement
distresses, utility conflicts, and ADA measurements
directly into project basemaps, reducing errors and
accelerating quality control.
Our design team applies a risk-based decision-making
framework that evaluates constructability, long-term
performance, and community impact. Rather than
relying solely on standard treatment templates, we tailor
pavement rehabilitation strategies and ramp designs
to specific field conditions, such as slope corrections,
private encroachments, and utility constraints. This
approach allows the City to select construction methods
that minimize disruption and extend pavement life while
maintaining cost efficiency.
To enhance communication, HR Green promotes hands-on
collaboration with City staff and stakeholders through joint
field walks, focused technical meetings, and plan review
workshops. This iterative coordination ensures that design
intent, accessibility compliance, and constructability are
fully aligned before PS&E submittals. We also incorporate
early contractor-style constructability reviews during
design development to identify potential issues, such
as drainage conflicts, phasing challenges, or utility
adjustments, well before bidding.
In addition, HR Green’s standardized QA/QC process
uses digital markups, structured checklists, and internal
peer reviews across multiple disciplines. This multi-
layer review system ensures consistency in plan quality,
adherence to City and Caltrans standards, and readiness
for construction.
These innovative practices, rooted in technology,
transparency, and data, ensure the City of Diamond Bar
receives a quality, cost-effective design that is ready for
efficient bidding and construction.
HR GREEN’S APPROACH TO SURFACE
TREATMENT AND REHABILITATION
HR Green’s pavement design philosophy is grounded in
data-driven decision-making and field-verified engineering,
ensuring that the City of Diamond Bar’s investments align
with the 2025 Pavement Management Program (PMP)
update recommendations. Our approach combines the
PMP’s analytical foundation with our extensive experience
delivering municipal pavement rehabilitation programs
across Southern California, ranging from preventive
surface treatments to full-depth reconstruction.
RESIDENTIAL AND COLLECTOR STREET
REHABILITATION
Residential and collector streets often exhibit a broad mix
of surface distress, including weathering, block cracking,
and localized base failures. Consistent with the PMP, HR
Green will begin with field verification of PCI data and
pavement coring to confirm layer thickness, interlayers,
and subgrade strength. Based on these findings, we
will identify the most cost-effective treatment for each
segment, typically slurry seal, cape seal, thin overlay, or
localized dig-outs.
HR Green has designed numerous residential rehabilitation
programs using similar treatments in Southern California
communities such as Pomona, Jurupa Valley, Hemet, and
Palos Verdes Estates where we successfully extended
pavement life cycles through selective overlays and
cost-effective preventive maintenance for their annual
neighborhood rehabilitation programs. Our focus will be
on optimizing surface performance and constructability,
maintaining access for residents, and coordinating ramp
upgrades to minimize conform limits.
ARTERIAL STREET REHABILITATION
Arterial corridors demand high-performance rehabilitation
methods capable of withstanding heavy traffic loads
and extended service life. Building upon the PMP’s
recommendations for overlay and reconstruction of
arterials with PCI values below 65, HR Green will evaluate
options such as asphalt rubber hot-mix (ARHM) overlays,
conventional grind-and-overlay, or full-depth reclamation
(FDR) where structural distress is significant.
Our team has extensive experience designing arterial
overlays for cities like Rancho Cucamonga, Moreno Valley,
and Jurupa Valley where we have developed numerous
arterial street rehabilitation plans utilizing data driven
decisions. We will also incorporate Complete Streets
elements, such as restriping for bike lanes and improved
crosswalks, consistent with City policy. We used this same
approach in Moreno Valley where we took the City’s newly
adopted bicycle master plan and incorporated miles of
new bike lanes in conjunction with their Citywide arterial
Page 8
FY 25/26 CIVIL ENGINEERING DESIGN SERVICES FOR: Residential & Collector Streets Rehabilitation, Arterial
Streets Rehabilitation, and Residential Neighborhood ADA Curb Ramps Improvement Project
Z City of Diamond Bar
pavement rehabilitation program. Phasing and traffic
control strategies will be developed to maintain mobility
and minimize impacts to businesses and residents along
these key corridors.
ADA CURB RAMP IMPROVEMENT PROJECTS
Consistent with the PMP and the City’s ADA Transition
Plan, HR Green’s approach focuses on achieving full
PROWAG and Caltrans compliance while resolving
drainage, slope, and encroachment challenges typical
in established neighborhoods. We will field-verify each
existing ramp, document deficiencies, and prioritize
upgrades based on constructability, cost, and accessibility
impact.
Drawing from our experience delivering hundreds of
ADA-compliant ramps for municipalities such as Diamond
Bar, Chino, and Rancho Cucamonga, we will prepare
detailed design sheets addressing grading transitions,
cross-gutters, and surface drainage to ensure long-term
durability and compliance. Each ramp location will be
coordinated with adjacent pavement improvements to
maintain smooth transitions and positive drainage.
OVERALL PROGRAM INTEGRATION
HR Green’s team will ensure each treatment type,
preventive surface seal, structural overlay, or full
reconstruction, is applied where it provides the maximum
return on investment. By combining the PMP’s network-
level recommendations with project-level engineering
analysis, we will deliver a coordinated set of PS&E
packages that are cost-effective, constructible, and
aligned with the City’s goal to maintain a “Good” or better
PCI citywide.

ADA Ramp Services
HR Green provided full plan
preparation for 135 arterial/
collector street segments
totaling over 80 centerline
miles. To expedite the
project, HR Green assigned a
comprehensive design team to
conduct field reviews, mapping,
utility coordination, pavement
recommendations, and signing/
striping plans per the City’s
circulation and bicycle master plans.
The project included grinding,
overlaying, or slurry sealing arterial
and collector streets citywide. In
addition to pavement rehabilitation,
the work involved new signing,
striping, Class II/III bikeways, and
bicycle boulevards. HR Green
designed corridors accounting for
the City’s bicycle/pedestrian plan
and existing parking. The project
also upgraded more than 200 ADA
ramps.
At the City’s request, HR Green
completed the first project
within 6 months and the second
in 4 additional months.
The $50 million Citywide Pavement
Rehabilitation Program - Phases 1
and 2 significantly improved road
quality, safety, and access. Originally
planned for 10 years, the project
was completed in just 18 months
using federal recovery and state gas
tax funding.
“The program condensed ten years
of work into only 18 months. I am
proud of our incredible team that
brought this project to life and saw
Phases One and Two through to
completion.”
- Ulises Cabrera, Mayor
From preliminary evaluation through final
construction documents, our team is involved
every step of the way. We develop innovative
design treatments tailored to each unique

2021-2022 Citywide Arterial Pavement Rehabilitation
HR Green provided the street improvement and signing and striping plans
for more than 80 miles of arterial/collector streets between two projects
and ten phases. The project included the grind and overlay or slurry
seal of arterial or collector streets throughout the City. In addition to the
rehabilitation or maintenance of existing pavement, the project also included
new signing and striping of all streets, including the addition of new Class
II and Class III bikeways as well as several bicycle boulevards. HR Green
had to take into the account the City’s adopted bicycle and pedestrian
master plan and existing on-street parking to design the most effective and
efficient corridors. At the City’s request to expedite the project, HR
Green was able to complete the design of the first project within six months
and the second four months after that.
Innovative strategies like project bundling and single contract awards were used to cut
costs, streamline processes, and meet the 18-month project delivery goal. The project was
a collaborative effort, with design provided by HR Green. Multiple contractors were hired due
to the demanding schedule, including All American Asphalt, Hardy & Harper, and RJ Noble.
This project was recognized by the League of California Cities (Cal Cities),
County Engineers Association of California (CEAC), and California State
Association of Counties® (CSAC) with the 2024 Outstanding Local Streets and
Roads Project Award.

Towne Avenue Improvements
Towne Avenue is a main corridor and is only one of two roads in Claremont
with access to the 210 freeway, making it one of the heaviest used routes
in the city. HR Green provided design services for improvements to Towne
Avenue that incorporated “Complete Streets” elements. This design included
the addition of new landscaped medians down the center of Towne Avenue
and tree wells along the sidewalks on both sides of the street. New bulb outs
were also incorporated into the design to slow down traffic and allow for a
more comfortable and safer path for pedestrians when crossing the street.
New Class IV protected bike lanes and bike boxes at the intersections were designed to
increase visibility and better serve bicyclists, while improving the drivability of the road
for motorists. Driving lanes and bike paths have been designed to be separated by small,
landscaped medians reducing stress of both bicyclists and motorists. Green paint was
added to bike lanes in areas where drivers and cyclists are at a higher risk of colliding.
Green bike lanes make drivers and bicyclists more aware of each other as they share
the road. This increased visibility enhances safety by reducing collisions. Traffic signal
enhancements were also part of the project. Such improvements included upgraded
signal lights, Intelligent Accessible Pedestrian Systems (APS) and new video detection.
Other features and amenities included pavement rehabilitation, landscape, and hardscape
upgrades. Such features included sidewalk and driveway replacement.

Baseline Road Pavement Rehabilitation
HR Green provided improvement plans, including separate signing and

estimates for the rehabilitation of Baseline Road between Etiwanda Avenue
and I-15. This segment of Baseline Road was experiencing some minor
distress, mainly longitudinal and block cracking of the existing wearing
course with potholes throughout. HR Green performed a thorough field
reconnaissance to identify areas in need of full depth replacement. The
replacement of existing ADA facilities was also provided with a detailed
survey and design of each individual access ramp. All existing traffic signals were upgraded
to include vehicle and bicycle video detection. In order for the project to proceed to
construction HR Green staff coordinated with Caltrans to obtain an encroachment permit for
the work affecting state right-of-way.
“I would like to express our sincere appreciation to HR Green for their contribution to delivering Civil
Design project plans to our Engineering Department. We thank HR Green for their professionalism and
experience in providing Civil Design for various projects. We highly recommended the HR Green team

CITY OF LAGUNA HILLS
La Paz Road Pavement Rehabilitation: HR Green provided
improvement plans, including separate signing and striping plans with the
addition of bikeways where feasible, while maintaining the existing travel
lanes, specifications, and cost estimates for the rehabilitation of La Paz
Road between the westerly city limits and Alameda Avenue in the City
of Laguna Hills. This segment of La Paz Road was experiencing minor
distress, primarily longitudinal and block cracking of the existing wearing
course, with potholes throughout.
HR Green performed a thorough field reconnaissance to identify areas
in need of full depth replacement. Due to settlement at an existing
pedestrian undercrossing, the plans called for the use of a roadway leveler/stabilizer
utilizing a polymer injection technique to mitigate the dip in the roadway at the culvert.
The replacement of existing ADA facilities was also addressed, with a detailed survey
and design of each individual access ramp. To advance the project to construction,
HR Green staff coordinated with Caltrans to obtain an encroachment permit for work
affecting state right-of-way at the SR 73 on/off ramps.
“HR Green staff members have provided consistent and excellent services for the City for the past 20

FY 25/26 CIVIL ENGINEERING DESIGN SERVICES FOR: Residential & Collector Streets Rehabilitation, Arterial
Streets Rehabilitation, and Residential Neighborhood ADA Curb Ramps Improvement Project
Z City of Diamond Bar
Chase Keys, PE
Project Manager
Chase has managed the design of arterial and residential street resurfacing and pavement
rehabilitation projects throughout Southern California. In the last five years alone, Chase
has overseen the design and/or construction of more than 230 centerline miles
of roadway reconstruction, mill/overlay, slurry seal, or chip seal. More than 80
miles were part of a $40 million ARPA-funded multi-award-winning citywide
paving program, including reconstruction, overlay, crack/slurry seal, and PCC
improvements.
SELECTED PROJECT EXPERIENCE
Z Citywide Arterial Pavement Rehabilitation Program, City of Moreno Valley
Project Manager responsible for the award-winning street improvement and signing and
striping plans for over eighty (80) miles of arterial/collector streets. The project included the
grind and overlay or slurry seal of streets throughout the City. In addition to the rehabilitation
or maintenance of existing pavement, the project also included new signing and striping of
all streets, including the addition of new Class II and Class III bikeways as well as several
bicycle boulevards. HR Green had to take into the account the City’s adopted bicycle
and pedestrian master plan and existing on-street parking to design the most effective
and efficient corridors. At the City’s request to expedite the project, HR Green
successfully completed the design of all 40 miles within 10 months.
Z Citywide Pavement Rehabilitation Program, City of Jurupa Valley
Project Engineer responsible for the design of a $9M Citywide neighborhood pavement
rehabilitation program spanning seven (7) project phases. Prior to completing PS&E
packages, performed “windshield surveys” of all local streets within the City (approximately
190 centerline miles) in order to assign treatment recommendations and prioritize projects.
In just 18 months completed the design as well as performed construction management of
all 7 projects totaling roughly 40 centerline miles of streets.
Z Citywide Pavement Rehabilitation Program, City of Hemet
Project Manager responsible for the street improvement plans and signing and striping plans
for various streets in Hemet. Based on the pavement evaluation it was decided to use ARHM
as the final wearing surface throughout the project. In addition to the pavement rehabilitation
and new signing and striping, all existing ADA access ramps were measured for compliance
and any non-compliant ramps were called to be removed and replaced.
Z Foothill Boulevard Pavement Rehabilitation, City of Rancho Cucamonga
Project Manager for the rehabilitation of a 2.5 mile stretch of Foothill Boulevard from Milliken
Avenue to East Avenue. The design included a cold mill and overlay of the existing AC
pavement. The revised signing and striping plans included not only the three existing travel
lanes in each direction, but the addition of new Class II bike lanes throughout the corridor,
some of which being buffered. This portion of Foothill Boulevard is directly adjacent the
City’s Victoria Gardens Mall and Interstate 15 and experiences heavy traffic. Careful planning
was needed so that the new Class II bike lanes would be accessed safely by the City’s
bicyclists. The design also included the upgrade of all existing traffic signals from loop to
video detection.

ADDENDUM NO. 1
CITY OF DIAMOND BAR
This Addendum No. 1 modifies and supplements Section III – Scope of Services of the Request
for Proposals (RFP). The following project descriptions provide additional technical details and
design expectations for each pavement rehabilitation component. All Consultants shall
incorporate these requirements into their proposals and associated cost submittals.
Residential & Collector Street Project
Under the City’s 2025 Pavement Management Program, the City is divided into seven (7)
pavement management areas. This project encompasses Areas 5 and 6 (see Exhibit B).
The Consultant shall prepare Plans, Specifications, and Estimates (PS&E) for the rehabilitation
of residential and collector streets identified in the 2025 Pavement Management Program.
Recommended pavement treatments may include, but are not limited to, slurry seal, chip seal,
grind and overlay, full-depth reclamation, localized dig-outs, or other appropriate pavement
preservation or rehabilitation strategies based on field verification and pavement condition data.
The Consultant shall evaluate all cross-gutters within the project limits and recommend
reconstruction where existing 1-inch channels or drainage deficiencies are observed, provided
sufficient longitudinal grade allows for correction. The Consultant shall identify, document, and
incorporate all cross-gutter removals and replacements in the construction plans.
Arterial Street Project
This work includes the rehabilitation of the City’s primary arterial corridors, Grand Avenue,
Diamond Bar Boulevard, along with select collector streets identified in the 2025 Pavement
Management Program (see Exhibit A).
The Consultant shall prepare full PS&E documents for the recommended arterial and collector
roadway segments. The Consultant shall verify pavement condition data, conduct field
inspections, and finalize appropriate rehabilitation strategies for each segment.
The design shall integrate bikeway and striping improvements consistent with the City’s General
Plan Circulation Element, Complete Streets policies, and applicable Caltrans standards. The
limits of work for each arterial segment are shown in the Arterial Project Limit Map (Exhibit C).
Curb Ramp Project
The City will utilize Community Development Block Grant (CDBG) funds to construct or upgrade
ADA-compliant curb ramps within Areas 6, 7, and 1. CDBG funding will be used exclusively for
construction, while local funds will support design services.
The Consultant shall evaluate existing curb ramps within each of the identified areas and
recommend approximately eight (8) locations per area for installation or upgrade. The
Consultant shall prepare complete PS&E documents for these improvements in full compliance
with the Americans with Disabilities Act (ADA), Caltrans Standard Plans, and the Public Rights-
of-Way Accessibility Guidelines (PROWAG).

ADDENDUM NO. 3
CITY OF DIAMOND BAR
This Addendum No. 3 is issued to notify all prospective proposers of revisions and clarifications
to the RFP. All other terms, conditions, and requirements of the RFP remain unchanged. The
following sections outline the General Revisions and Questions and Responses associated with
this addendum.
General Revisions
As part of this Addendum, Projects 6 through 9 have been moved from the Base Fee Schedule
to the Optional Items section. See attached revised Exhibit E – Base Fee Schedule.
This revision reflects adjustments to the City’s anticipated design priorities and available funding
allocations. The City reserves the right to select, modify, or reprioritize specific projects and
streets for design within each fiscal year, based on available funding, operational priorities, or
coordination with other city programs and capital improvement efforts.
Questions and Responses
Question 1:
For Section C (“Samples of Previous Work Product”), can the city clarify what type of materials
are expected? For example, would you prefer plan sheets or design deliverables, or would
narrative summaries similar to the three comparable projects be acceptable?
Response:
It is unclear which Section C is being referenced in the question. However, Subsection C under
Section IV – “Proposal Content & Format” requests proposers to provide a brief history of the
firm and comparable public works projects completed.
If the intent of the question is to clarify the requirement for “Samples of Previous Work Product,”
proposers may include representative plan sheets, design deliverables, or concise narrative
summaries that demonstrate the firm’s relevant experience on comparable projects.
Question 2:
The RFP states that “For Project 7 identified in the Base Fee Schedule (Area 6 Residential and
Collector Streets Rehab), certain design elements shall be fully designed……..the Consultant
shall develop complete design sheets and supporting details…..will not require a full PS&E
package at this time……” Can you elaborate more on what is specifically required at this time
then? i.e., 60%, 90%, or 100% plans? Engineer’s Estimate? No Specifications?
Response:
Project 7 has been replaced with Project 9 (Arterial Street Rehabilitation: Temple
Avenue/Avenida Rancheros – Diamond Bar Blvd. to City Limits).
Project 9 is located along the City’s boundary with the City of Pomona, where Pomona owns
and maintains one side of the roadway and the City of Diamond Bar is responsible for the other
(see google map). The Diamond Bar half of the roadway shall be fully designed as part of the
design contract. The Consultant shall prepare a full PS&E package for the City’s side of the
Page A-8

Streets Rehabilitation, and Residential Neighborhood ADA Curb Ramps Improvement Project
Z City of Diamond Bar
ADDENDUM NO. 3
roadway and coordinate with the City of Pomona to ensure design continuity across the
centerline.
Question 3:
The RFP indicates “for current FY 2025-26 Area 6 (CDBG) ADA curb ramps and arterial
locations listed in the table, Section III.” Will that be the first design project in the 3-Year
Pavement Design Program? And the Residential Areas 5 and 6 the next 2 years’ projects? Can
the City provide which of the 10 projects listed are anticipated to be designed together and in
which of the 3-Year Program? That will help in preparing our Estimated Labor Hours, as
requested, knowing how many PS&E packages will be prepared.
Response:
Projects 1 and 2 are anticipated to be designed during Year 1 of the three-year pavement
design contract. The city will request the Consultant to proceed with the design of the remaining
projects in subsequent years.
As stated in Section III of the RFP, the City reserves the right to select, modify, or reprioritize
specific projects and streets for design within each fiscal year based on available funding,
operational priorities, or coordination with other City programs and capital improvement efforts.
Question 4:
Are full geotechnical services being requested for all roadways? i.e., to provide pavement
coring, lab testing and results, and pavement evaluation and rehabilitation recommendations?
For the residential areas, does the City have a standard or policy of how many/how often coring
are typically taken? Also, does the city want to consider Deflection Testing and Analysis, and/or
Ground Penetrating Radar (GPR) Testing and Analysis services for any/all of the roadways?
Response:
Yes, pavement coring for both residential and arterial roadways will be essential to the design
effort. The city will rely on the Consultant’s professional judgment to determine the appropriate
number and locations of pavement coring for each area type (residential and arterial) to ensure
adequate representation of existing pavement conditions.
The City does not have a set standard or policy dictating coring frequency; however, the
Consultant should propose a reasonable and data-driven sampling plan based on field
conditions and project scope.
During construction, the project specifications shall require the contractor to perform pavement
testing, while the city will conduct its own independent lab testing as part of construction quality
assurance.
At this time, the city does not require Deflection Testing or Ground Penetrating Radar (GPR)
Testing as part of the base scope but may consider them as optional services pending initial
field investigation results.

Z City of Diamond Bar
ADDENDUM NO. 3
Question 5:
In addition to the ADA curb ramp compliance improvements (8 each in Areas 1, 6, and 7), is it
the City’s intent to analyze any other ADA paths of travel issues such as across driveway
aprons, etc.? Or is that not part of the scope of work for this project?
Response:
The scope of work is focused on the ADA curb ramp compliance improvements identified for
each area; however, the Consultant shall also evaluate adjacent cross gutters and spandrels
associated with each ramp location. Recommendations for repair or replacement of these
elements shall be included as part of the ADA curb ramp design scope where necessary to
ensure compliance and proper drainage. Evaluation of other path-of-travel elements, such as
driveway aprons or sidewalks beyond the immediate ramp and cross-gutter limits, is not
required unless otherwise directed by the city.
Question 6:
It is noted that all Arterial Street designs shall include the evaluation and integration of new or
improved bike lanes. Is it assumed then that signing and striping on all other streets (residential
and collectors) are to be replaced in kind?
Response:
Yes, that assumption is correct. Signing and striping on residential and collector streets shall be
replaced in kind, while arterial street designs shall include the evaluation and integration of new
or improved bike lanes as part of the project scope.
Question 7:
What will the Consultant’s level of involvement be with coordination and/or permitting with other
agencies? (i.e., Caltrans, L.A. County, adjacent municipalities, etc.)
Response:
The Consultant shall be responsible for preparing and obtaining all necessary clearances and
permits from other agencies, such as Caltrans, Los Angeles County, or adjacent municipalities,
as required for project implementation. The city will provide support and coordination assistance
as needed, including review, signature, and transmittal of official correspondence.
Question 8:
Is Golden Springs Drive included or excluded from the Area 6 Project?
Response:
Golden Springs Drive is excluded from the Area 6 Project, as it was recently completed under
the City’s Arterial Rehabilitation Project.
