RE: Kerper Court and Kerper Boulevard Intersection Improvement Project
INTRODUCTION
The purpose of this memorandum is to authorize the public bidding procedure for
Kerper Court and Kerper Boulevard Intersection Improvement Project.
BACKGROUND
The Kerper Court and Kerper Boulevard intersection is currently a T intersection with
Kerper Court as a STOP controlled intersection. The businesses on Kerper Court are
Anderson Window & Door, Municipal Services Center, Bard Concrete and Lamar Sign.
Kwik Trip has purchased the property on the south side of Kerper Court at Kerper
Boulevard. They are planning on building a gas/convenience store at this location.
As part of the conceptual site plan review process with the City Development Review
Team, a traffic impact study (TIS) was required. The developer hired Kimberly Horn to
complete the TIS. The City met with Kimberly Horn to discuss the study and Kimberly
Horn submitted a TIS to the City for review.
The results of the TIS show that traffic safety improvements will be required immediately
after development of the gas/convenience store at the intersection of Kerper Court and
Kerper Boulevard. The TIS recommended that a traffic signal or roundabout be installed
at the intersection to provide an acceptable level of service.
DISCUSSION
When planning for intersection improvements, the City of Dubuque prefers roundabouts
to traffic signals whenever appropriate conditions exist. Benefits of roundabout
intersections are many and include the following:
1. Roundabouts save the taxpayers money in maintenance and electricity costs
over the life of the project.
2. Roundabouts are easier to maintain than signalized intersections.
3. Roundabouts are safer for pedestrians/bicyclists and prevent head on or T-bone
crashes.
4. Roundabouts offer improved flexibility for business access/Roadway locations.
5. Roundabouts effectively and safely slow traffic and improve traffic flow.
6. Roundabouts are being added by local and state governments across the US.
Today, they are commonplace for large vehicle operators such as semi or dump
truck drivers.
7. Roundabouts reduce fuel consumption and save money, especially for truck
drivers.
8. Roundabout reduce green house gases by minimizing idling at the intersection.
Combined with improvements in safety and traffic flow, recent studies on roundabouts
have demonstrated the potential to improve the local business climate. The economic
benefits of roundabouts include:
1. Inviting. Roundabouts provide green space, generally have little or no congestion,
and allow for easy access to destinations (including U-turns). All factors that make
an area more aesthetically pleasing and inviting.
2. Connectivity. Roundabouts can be an integral part of a bicycle and pedestrian
friendly area, particularly due to forcing slower vehicle speeds and potentially
reducing crossing distances/vehicle exposure for pedestrians. This translates into a
more secure sense of the area and greater connectivity to the surrounding
neighborhoods when people are able to walk and bike.
3. Greater Visibility. Slower vehicles speeds mean drivers and passengers have time
to see the businesses in the area, increasing the likelihood of stopping and
shopping.
TEMPORARY DETOUR ROADWAY
The City has been constructing a temporary roadway on private property between
Kerper Court and 16t" Street to accommodate the construction project. (Exhibit A) By
constructing this temporary roadway all the businesses on Kerper Court will be able to
travel to and from their place of business without having to go through the construction
area. This roadway will not only eliminate the need for additional phasing of the project
but will be a much safer situation for the traveling public and the construction workers.
This roadway was constructed by City Public Works and Engineering staff with the aid
of a contractor to core out the roadway and place road base. Thousands of dollars were
saved by doing most of the work in house without detailed plans and specifications.

PUBLIC OUTREACH
Engineering staff working in conjunction with the Public Information Office are preparing
brochures and letters to contact all the abutting property owners on Kerper Boulevard
from 12th Street to Hawthorne Street about the project. Additionally, engineering staff
have had one-on-one conversations with the property owners on Kerper Court and
those directly abutting the intersection. A public information meeting has been
scheduled for June 8th, 2023 to be held at the Municipal Services Center from 4:00 pm
to 6:00 pm.
RECOMMENDATION
I recommend preliminary approval of the proposed plans, specifications, form of
contract and construction estimate for the Kerper Court and Kerper Boulevard
Intersection Improvement Project. I further recommend establishing the date of the
public hearing and authorizing the Engineering Department to advertise for bids for the
Project.
BUDGETIMPACT
A Development Agreement has been entered into between the City and Kwik Trip,
portions of the Development Agreement that pertain to the intersection improvements
include the following:
1. City agrees to design and construct the required Kerper Boulevard and Kerper
Court Roundabout Improvement Project. The estimated cost of the required
improvements is one million five hundred thousand dollars ($1,500,000).
Required intersection improvements include but are not limited to roundabout,
lane widening, lighting, underground utilities, crosswalks, sidewalks and curb
ramps.
2. Kwik Trip agrees to place $750,000 in escrow to be utilized for the construction of
the required intersection improvements, including but not limited to engineering,
right of way acquisition and construction.
3. City agrees to make a good faith effort to construct the required intersection
improvements so that they are operational by November 30, 2024.
4. Developer agrees to pay 50% not to exceed $750,000 of the actual costs of the
required intersection improvements, including but not limited to engineering, right
of way acquisition, and construction.
The estimate of probable cost for Kerper Court and Kerper Boulevard Intersection
Improvement Project is as follows:
Description
Cost Estimate
Construction Contract
$ 1,327,497.00
Contingency (10%)
132,750.00
Construction Engineering & Inspection (12%)
175,230.00
Temporary Road Construction
$60,000.00
Total Construction Cost Estimate
$ 1,695,477.00
3
The construction of the temporary road greatly reduces the complexity of the traffic
phasing during construction and provides improved access to the abutting property
owners. It's anticipated the construction cost will be reduced due to this preemptive
traffic accommodation.
