SUBJECT: Resolution Authorizing Award of Contract for the Left -Tum
Protective/Permissive Traffic Signal Modification Project
RECOMMENDATION
Staff recornmends that the City Council approve the attached resolution authorizing the award of
contract for the Left -Turn Protective/Permissive Traffic Signal Modification Project and
Authorizing the City Manager to Execute the Necessary Project Documents.
BACKGROUND
On March 1, 2010, City Council Adopted Resolution No. 2010-031 N.C.S. accepting the Cycle 3
Federal Highway Safety Improvement Program Grant for the Protected Left -Turn Signal
Upgrade Project. A Traffic Safety Evaluation Report for the City of Petaluma was completed by
the Institute of Transportation Studies at University of California Berkeley in collaboration with
the City of Petaluma Police Department to evaluate the protected/permissive left -turn signal
operations. The study was initiated because right-of-way collisions surpassed speed collisions as
the highest cause of collisions in Petaluma. Right-of-way collisions are defined as those
accidents that do not related to speeding but are caused when a driver neglects to yield the right-
of-way to another vehicle. An example would be a driver who pulls out in front of on -coming
traffic to make a left turn. This is significant because excess speeds in most jurisdictions are the
highest cause of collisions.
There are 26 protected/permissive left -turn signal intersections within the City of Petaluma.
These intersections operate as follows: the protected green arrow turns to a regular green light
termed a permissive left turn after a specified duration. The danger is that a driver can assume
that there is no on -coming traffic once the permissive green light illuminates and can make a bad
last-minute decision to pull out and attempt to turn left. This can cause an accident if on -coming
traffic is present.
In an effort to reduce these types of collisions, the subject project will upgrade 23 of the 26
intersections by replacing the protected/permissive signal housing with a protected left -turn only
and flashing yellow arrow signals. Three additional intersections located at Rainer at N.
Agenda Review:
City Attorney Finance Director City Manager
McDowell; Ellis/Johnson at E. Washington; and Stony Point at Old Redwood Highway, will be
upgraded by private development or the State Department of Transportation (Caltrans) in the
near future. Caltrans and the Federal Highway Administration (FHWA) have approved the
flashing yellow arrow signal technology. With this technology, the left turn portion of the signal
will begin as the customary green left pointing arrow for a set duration. The next phase will
move to a solid yellow arrow to keep additional cars from initiating a left tum movement. The
solid yellow arrow is followed by a red solid arrow of sufficient duration to clear the intersection
of cars turning left. Following the solid red and after the intersection is clear of left turning
vehicles, the signal will begin a flashing yellow arrow to permit drivers to make a left turn when
on -coming conditions are clear. The Police Department will lead the public outreach program
regarding the new signal type.
The proposed action meets Council Goal: "Plan for and implement priority capital projects as
funding permits."
DISCUSSION
The Notice Inviting Bids was issued on January 30, 2014. On February 26, 2014, 4 bids were
received as follows:

The lowest responsible bidder, DC Electric Group, Inc., has performed similar projects for the
City of Petaluma. Staff verified that Contractor possesses a valid C-10 California Contractor's
License, license number 949934, which expires on October 31, 2015, which qualifies Contractor
to perform the work. ,
In light of the low bid amount, City staff investigated the possibility of upgrading all signal head
lenses at the 23 intersections from 8" to 12" LED lenses to meet current traffic signal standards
as well as to maximize the 90% safety grant funding. An estimate of $51,984 was submitted by
the Contractor to complete this work and then provided to Caltrans for review and authorization
to proceed. Caltrans has given the City an initial verbal authorization to proceed and will follow
up in writing before the City moves forward. Once authorized, the additional work will be
included as Contract Change Order No. 1.
The funding for the change order will be added to the estimated construction contingency. The
change order and contingency increase will not require additional local match contributions
based on the currently approved budget.
Construction is tentatively scheduled to begin in April of 2014 and to be completed by June of
2014. It is anticipated that inspection and construction management will be conducted by City
staff. Engineering services during construction will be performed by the traffic engineering
design consultant, W -trans.
