INTRODUCTION
The enclosed resolution is in reference to the public hearing on the Traffic Signal
Mastarm Retrofit Project, Central Avenue at Stn and 7tn Streets.
BACKGROUND
Currently Central Avenue contains a mix of pedestal-mounted and mastarm-mounted
heads. The differing location of the traffic signals sometimes leads motorists to react to
the second signal ahead as opposed to their nearer intersection.
DISCUSSION
This project provides for the standardization of mastarm-mounted signals along the
Central Avenue corridor. The project will also include: pre-emption capabilities; battery
back-up systems; fiber optic inner-connect between the signals; and some monitoring
equipment that will allow remote management via the Traffic Operation Center. New
traffic controller equipment and mastarms have already been purchased for the project
to eliminate the long lead time in ordering.
BUDGET IMPACT
The estimate of probable cost for the Traffic Signal Mastarm Retrofit Project, Central
Avenue at Stn and 7tn Streets is summarized as follows:
Estimate
Construction Contract $159,500.00
Contingency 15,950.00
Construction Engineering & Inspection 26,317.50
Total Project Cost $201,767.50
The funding for the Traffic Signal Mastarm Retrofit Project, Central Avenue at Stn and 7tn
Streets will be as follows:
CIP No. Fund Description Fund Amount
1001133 Traffic Signal Mastarm Retrofit $ 93,430.99

1021609 Fiber Optic Conduit -Private & Miscellaneous 15,836.51
Total Project Funding $201,767.50
RECOMMENDATION
I recommend that the City Council approve the plans, specifications, form of contract
and the estimated cost for the Traffic Signal Mastarm Retrofit Project, Central Avenue at
Stn and 7tn Streets.
