1.0 INTRODUCTION

The City of Stockton (City) requests a Technical Proposal from qualified consulting firms

to provide professional consultant services to design a new traffic signal at the

intersection of Airport Way and 6th Street and synchronize signals along Airport Way

between Dr. MLK Jr. Blvd and Arch Airport Rd. A selection committee will

comprehensively rank firms based on, but not limited to, proposals, qualifications,

references, and other relevant information.

The Consultant must be familiar with Congestion Mitigation and Air Quality (CMAQ) and

Carbon Reduction Program Local (CRPL) funded projects, Caltrans Local Assistance

Programs Guidelines (LAPG) and Local Assistance Procedures Manual (LAPM).

Likewise, the Consultant and Consultant staff must demonstrate recent roundabout

design experience. The consultant shall also provide assistance during the construction

phase of the project.

2.0 BACKGROUND

The City recently secured CMAQ/CRPL funds for the design and construction of a new

traffic signal at the intersection of Airport Way and 6th Street. The project proposes to

replace the current one way stop sign at the T-intersection of Airport Way and 6th Street

with a traffic signal to reduce congestion and improve safety by reducing unprotected

turns. Currently the intersection operates at a level of service (LOS) D experiencing

peak congestion between 7:00am to 7:30pm during weekday hours. Airport Way is an

existing two-way median barrier separated road running northwest/southeast bound

traffic. 6th Street is a residential corridor running east/west bound traffic to Airport Way.

3.0 PROJECT DESCRIPTION

The proposed project converts an existing stop sign at the T-intersection of Airport Way

and 6th street to a traffic signal. In addition, coordinate signalized intersections along

Airport Way from Dr. Martin Luther King Jr. Blvd to Arch Airport Road.

(See Attachment A – Vicinity Map).

4.0 SCOPE OF WORK

Each consultant shall prepare a detailed scope of services for the design of this project

based, in part and at a minimum, on information presented in this Request for Proposal,

and other available information. The consultant shall provide a cost proposal, which

accomplishes the objectives of the project.

The consultant shall incorporate in their design the installation of the traffic light at the

Airport Way and 6th Street intersection, including synchronization to City infrastructure

throughout the intersections along Airport Way from Dr. Martin Luther King Jr. Blvd to

Arch Airport Road.

Consultants are encouraged to include items that are thought necessary for this project.

4.1 Background Research

The consultant shall research and review existing topographic mapping, photos, right of

way maps, “as-built” plans, record maps, surveys, assessor maps, local street

improvement plans, collision reports, sight distance, approach speed, total pedestrians

and vehicle volumes, public transit routes, grade, need of advance warning signs and

flashers, and other geometrical and operational characteristics for the project.

The Consultant shall conduct field reconnaissance of the entire project limits. The

Consultant shall work with all pertinent utilities to identify conflicts, coordinate utility plan

reviews, conduct necessary coordination meetings, and locate designed improvements

as required to facilitate any utility relocations. The consultant will need to coordinate

with the City to the maximum extent possible to route this information to utility

companies. Consultant must show all existing utilities that will be impacted or cause

impact by the proposed project. The consultant is responsible for arranging and

coordinating with all utility companies, within the project sphere, to resolve any utility

issues.

The Consultant shall identify required permits, prepare all permit applications, and

assist the City with negotiations relative to permit conditions, if required. Permit fees will

be paid by the City.

4.2 Environmental Services

The project is funded with federal funds, and therefore California Environmental Quality

Act (CEQA) and National Environmental Policy Act (NEPA) compliance is required

through Caltrans District 10 Office of Local Assistance. The consultant shall be

responsible for coordinating with Caltrans and Stakeholders as needed, including

completion of the Preliminary Environmental Study (PES). Consultant will prepare any

studies that Caltrans requires in the approved PES.

The consultant shall be responsible for printing, mailing, delivering, and distributing to

appropriate Agencies and Stakeholders to obtain environmental clearance.

4.3 Utility Coordination

The consultant will be responsible for performing utility investigations and coordination

with utility owners throughout the project development process. The Consultant will be

present at all necessary meetings with each utility owner. The consultant will be

responsible for, but not limited to, the following:

• Prepare a project limits map and request utility information from each utility owner within

the area of work.

• Prepare Utility Letter “A” during preliminary design phase to the affected utility owners

for City to review and approve prior to transmitting to utility owners. Information on

existing utilities obtained as a result of the “A” letter will be transferred to base maps in

both plan and profile view. A copy of the utility data obtained from utility owners will be

provided to the City and the originals will be filed in the project files.

• Prepare Utility Letter “B” during 65% design phase to the affected utility owners for City

to review and approve prior to transmitting to utility owners. Two sets of half-sized 65%

plans will be provided to each utility owner as an attachment to the letter. The letter will

request that utility owners verify any utility conflicts with proposed improvements and

indicate whether any future utilities are proposed in the area that may require

accommodation through the improved area. Information on existing utilities obtained as

a result of the “B” letter will be used to determine potential utility conflicts and to resolve

the conflicts identified. A copy of the utility data obtained from utility owners will be

provided to the City and the originals will be filed in the project files.

• Prepare Utility Letter “C” during 100% design phase to the affected utility owners for

City to review and approve prior to transmitting to utility owners. Two sets of half-sized

100% plans will be provided to each utility owner as an attachment to the letter. The

letter will indicate to the utility owners whether any changes have been made to the

project plans since the Utility Letter “B” and will request written confirmation of utility

relocations and utility relocation schedule. A copy of the utility data obtained from utility

owners will be provided to the City and the originals will be filed in the project files.

• Consultant shall meet with utility companies as needed to ensure that conflicts are

identified and relocations performed if necessary.

• Consultant will use data provided by utility companies and perform field work such as:

potholing, ground penetrating radar, or other technology to confirm depth information.

This field work should be performed as soon as possible so that conflicts can be

identified, and utility companies can be notified of any necessary relocating.

4.4 Plans, Specifications, and Estimate

The Consultant shall prepare complete PS&E documents, which include design

improvement plans, traffic control plans, electrical plans, drainage plans, technical

specifications, and engineer’s estimate. The PS&E shall be prepared according to the

City’s standards and current CA MUTCD, as appropriate. Consultant shall use modeling

software to determine acceptable Level of Service (LOS) and geometric layout and

submit recommendations to City for concurrence. Prepare a base map showing

existing information to facilitate the design of all the necessary improvements. The

base map limits shall be sufficient to cover all necessary improvements within the

project area. Based on existing map information, some surveying work
