SUBJECT: Maus Park Lake Pump Station Culvert Repair Project
Project #5586500032
DATE: August 29, 2023
INTRODUCTION
The purpose of this memo is to seek authorization to initiate the public bidding process for
the Maus Park Lake Pump Station Culvert Repair Project.
BACKGROUND
Prior to the construction of the floodwall, a concrete arch culvert served to drain Maus Lake
beneath what are now Canadian National (CN) mainline railroad tracks to the Mississippi
River. When the floodwall was constructed, the existing arch culvert was retrofitted with
sections of 48-inch reinforced concrete pipe at the upstream and downstream ends to extend
the pipe. The flow line of the arch culvert was filled with concrete and formed to the radius
of a 48-inch pipe. A manually operated flood gate was installed at the downstream end, and
a pumping station was constructed at Maus Lake.
In May 2017, ballast subsidence under the railroad tracks was identified at the location of
the culvert crossing. Further investigation revealed joint openings in the concrete arch below
the tracks. The joint openings were filled with epoxy and steel plates were installed along
the roof of the pipe as a temporary repair measure until a permanent solution could be
developed.
DISCUSSION
The improvements associated with the Maus Park Lake Pump Station Culvert Repair Project
(Project) involves the lining of the culvert that allows stormwater runoff to pass from the
Maus Lake ponding area, under a set of two railroad mainline tracks, through the
floodwall/levee system, into the Mississippi. Specifically, the work consists of the
construction of a permanent cofferdam and concrete apron, concrete walls, and stop log
level control system on the interior side of the floodwall/levee system. Repair of the culvert
involves the trenchless installation of approximately 110 lineal feet of a steel slip liner inside
the existing culvert resulting in a new culvert under the railroad tracks, partially through the
levee.

PROJECT SCHEDULE
The schedule for the Project is as follows:

RECOMMENDATION
I recommend preliminary approval of the proposed plans, specifications, form of contract,
and construction estimate for the Maus Park Lake Pump Station Culvert Repair Project. I
further recommend establishing the date of a public hearing and authorization to advertise
for bids for the Project.
BUDGET IMPACT
The estimate of probable costs for the Project is as follows:
Construction Contract $586,000
Contingency 58,600
Engineering 96,700
Total Project Cost $741,300
The Project is to be funded through a FY23 appropriation in the amount of $463,940 for
Maus Park Culvert Restoration (Project 5586500032) with additional funds from an FY23
appropriation in the amount of $216,000 for Storm Sewer Replacements (Project
5586500001) and an FY23 appropriation in the amount of $118,500 00 for Storm Sewer
Improvements/Extensions (Project 5586500020).
The City has a pending claim (ICP047008A1) into the lowa Communities Assurance Pool
(ICAP) for making the permanent repairs to the culvert that would offset the City's cost to a
certain extent.
ACTION TO BE TAKEN
I respectfully request adoption of the attached resolutions preliminarily approving the
proposed plans, specifications, form of contract, and construction estimate; establishing the
date of the public hearing; and authorizing advertisement of bids for the Maus Park Lake
Pump Station Culvert Repair Project.
