2018-007 Small Intersection Improvement ProjectsDate: January 19, 2018 Report No. 2018-007
INFORMAL STAFF REPORT
TO MAYOR AND CITY COUNCIL
SUBJECT:
Small Intersection Improvement Projects
EXECUTIVE SUMMARY:
City Council recently approved funding for design and construction of Small Intersection
Improvement Projects at six (6) locations throughout the City. The majority of the locations
currently experience considerable traffic congestion during morning and afternoon peak hours.
As such, staff identified capacity and signal enhancements at each location that would help
alleviate the existing traffic issues. This report provides an overview of the proposed plan to
design and implement (construct) these small intersection improvements. The goal is to complete
these projects by end of 2018.
BACKGROUND:
At the August 26, 2017, City Council Retreat, the City Council gave direction to Staff to develop
a short term plan that would make immediate traffic flow improvements within the City. As a
result, traffic engineering staff identified six intersection improvements that would address
citizen complaints, alleviate congestion, and improve safety. The intersections were identified
based on the amount of traffic congestion, the ease of design and implementation, and the
immediate and noticeable impact to drivers.
In the December 12, 2017 meeting, City Council approved funding for the six Small Traffic
Improvement Projects. The estimated cost of the projects is shown in the table below.

Total $2,120,000
PROJECT STATUS:
Since, the City Council approval staff has worked on soliciting, reviewing, and shortlisting
qualified design firms suitable for these projects. Staff intends to engage the services of six
different design firms (one for each project) to expedite the design process and move the projects
on parallel tracks. The design for all the projects is anticipated to be completed by April 2018.
Subsequently, the projects will be divided into two groups with three projects in each group. The
bundled projects will be advertised and bid as two separate contracts for construction. The bid
Date: January 19, 2018 Report No. 2018-007
and award phase is anticipated during the summer months with the construction starting in fall
and completion by end of 2018.
The overall schedule for each of the project is shown below. Note that one of the projects (Dallas
Drive/Teasley Lane) is already under design and the surveying (first step of the design phase) for
the remaining projects will begin January 29, 2018.
CONCLUSION:
Staff plans to move these small intersection improvement projects through the design and
construction phase in an expeditious way to complete majority of the construction by end of
2018.
