MEMORANDUM
March 23, 2015
To: Impact Fee Advisory Committee
From: Bob Murray, Project Engineer 61M
Re: Baxter/Davis Intersection Improvements Project—Impact Fee Amendment Request
Baxter and Davis is the intersection of two minor arterials. The intersection has a failing level of
service during peak hour traffic. It is currently included in the FYI Impact Fee CIP for at
$750,000 which represents 60% of the estimated overall projects cost. The current Commission
policy is that intersection improvements are 60% impact fee eligible with the remaining 40%
coming from some other source.
The City has retained the services of Robert Peccia and Associates (RPA)to complete the design
of the improvements to the intersection. They are close to completing the predesign phase which
compares the installation of a signal versus a roundabout for the intersection control. This effort
will culminate with a Commission presentation tentatively scheduled for the 13t" of April at
which time they will make the final decision on which improvements to go forward with. The
traffic study prepared by RPA shows that either option will adequately handle the projected
future traffic.
As part of the predesign effort, RPA also prepared preliminary cost estimates for both options.
The estimate for a signal is $1,857,043 and for a roundabout $2,678,916. The reason for the
higher estimates is primarily due to the large amount of geometric improvements that need to be
completed as part of the project. Currently the east leg in only constructed to a county road
standard and will have to be replaced to provide the structural road section necessary to
withstand the anticipated traffic. Similarly, only half of the roadway is constructed on the north
leg. The east half of this leg will need to be entirely constructed with the project including tapers
back to the existing roadway. Schematic layouts and the estimates for each option are attached
for your information.
In order for the project to move forward, the Impact Fee CIP will need to be amended to cover
the higher than previously estimated costs. Engineering will be recommending the signal option
due to the lower capital costs, smaller amount of right of way necessary, and the fact that the
roundabout option would also require installation of pedestrian signals at each of the legs. As

stated above however, the decision is ultimately the Commission's on which option to
implement. As such, we are requesting that the Impact Fee Advisory Committee forward a
recommendation to amend the FY 15 Impact Fee CIP to raise the amount for this project to
$1,600,000 (rounded) which represents 60% of the roundabout option. If the signal is chosen,
only 60% of the lesser amount will be utilized on the project.
Let me know if you have any questions.
