RECOMMENDED ACTION:
1) Award the Engineering Design Professional Services Contract to Lee Engineering, LLC of Phoenix, Arizona in an amount not to exceed $99,660.00, including a $4,983.00 contract allowance and a calendar day contract period of 357 days; and
2) Approve Change Order Authority to the City Manager in the amount of $9,966.00 (10% of contract amount excluding allowance) for unanticipated or additional items of work; and
3) Authorize the City Manager to execute the necessary documents.

3) Authorize the City Manager to execute the necessary documents.
Policy Decision or Reason for Action:
Provide Engineering design services for the Butler Avenue Traffic Signal Control System.
Financial Impact:
The project cost including staff time, design and construction is estimated to be $450,000. The project is identified in the Community Development Division, Transportation Capital Improvement Program (Account #040-05-112-3055-6-4445), Project Number 925001, ST3355A.
Connection to Council Goal:
Maintain and deliver quality, reliable infrastructure.
Has There Been Previous Council Decision on This:
No
Options and Alternatives:
A) Approve the Award as recommended
Pros: This top priority traffic signal coordination project will proceed
Cons: Transportation Tax Traffic Flow and Safety Improvements Program Funds would not be available for lower priority needs
Cons: Transportation Tax Traffic Flow and Safety Improvements Program Funds would not be available for lower priority needs
B) Amend the Award Scope/Fee
Pros: Cannot be determined without knowing amendment
Cons: Additional staff time to discuss with Consultant
C) Reject the Award
Cons: Additional staff time to discuss with Consultant
Pros: This option would have the effect of being able to use funds for other signal improvements
Cons: Signals on Butler Avenue would not be coordinated
Cons: Signals on Butler Avenue would not be coordinated
Background/History:
A Request for Statements of Qualifications (RSOQ) for professional services was advertised on March 9 & 16, 2014. The City also directly notified several firms that specialize in traffic engineering. A Pre-Submittal Meeting was held on March 25, 2014 where four design firms were in attendance. Statements of Qualifications (SOQ) were due on April 7, 2014 and only one SOQ was received, from Lee Engineering, LLC. The SOQ was evaluated by a committee of 6 members, and it was determined that the SOQ was most qualified.
Butler Avenue is the only local east-west arterial corridor south of the railroad tracks and future growth in traffic volume is anticipated. This project consists of installing signal control technologies at six signalized intersections along Butler Avenue at the following intersections (see attached vicinity map):
Advanced Signal Control Technology receives field data in real-time and, through well-engineered signal timing, adjusts red and green times of all signals in the system based on actual field conditions. In contrast, Legacy Systems adjust red and green times based on predetermined time of day settings. In other communities, Advanced Signal Control Technology has proven to improve the quality of service that travelers experience through less delay, moving traffic more smoothly through the network. According to the FHWA these types of systems improve travel times by 10%-50% based on how outdated the existing timing plans are.

Key Considerations:
The project will not require additional right-of-way or change the existing configuration of the intersections.
There is existing signal communication conduit between the signals from Milton to Sawmill – 4700 linear feet.
There is no existing signal communication conduit from Sawmill to Ponderosa Parkway – 3800 linear feet.
Once the system is installed, it is planned to have an evaluation process to measure before and after Butler Avenue travel times, as well as other to-be-determined measures of effectiveness. These results will be reported and used to help determine future expansions of this type of signal system, which would benefit other city corridors.

Expanded Financial Considerations:
The Adaptive Signal Control Technology chosen and monitoring capabilities can be very sophisticated or relatively simple. The specific project design (concept of operation) will be established through two workshops and an implementation plan will be established by staff as constrained by our construction budget of approximately $300,000.
Community Benefits and Considerations:
System will reduce the number of stops and improve travel times along Butler Avenue.
Community Involvement:
Empower - Traffic signal coordination was approved by voters through passing of Proposition 403 (Traffic Flow and Safety Improvements - 0.186% Transportation Tax).
Consult - Citizen Survey and FMPO Trip Diary Survey regularly indicate the need to improve traffic signal coordination and overall congestion.
Inform - The scope of work for the design includes informational public meetings (Bicycle & Pedestrian Advisory Committees and the Transportation Commission).
