Van Milligen, City Manager SUBJECT: Maus Park Lake Pump Station Culvert Repair Project Project #5586500032 DATE: September 12, 2023 City Engineer Gus Psihoyos is recommending City Council adopt the attached resolution approving the plans, specifications, form of contract, and construction estimate of $586,000.00 for the Maus Park Lake Pump Station Culvert Repair Project. 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 railroad mainline tracks, through the floodwall/levee system, into the Mississippi. 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. In addition to lining the existing culvert, the work includes 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 which will both facilitate the lining process and allow for maintenance of the culvert once complete. The City has a pending claim (ICP047008A1) into the lowa Communities Assurance Pool (ICAP) for making the permanent repairs to the culvert that will offset the City's cost to a certain extent as determined by ICAP. I concur with the recommendation and respectfully request Mayor and City Council approval. � Mic ael C.

Van Milligen, City Manager FROM: Gus Psihoyos, City Engineer SUBJECT: Maus Park Lake Pump Station Culvert Repair Project Project #5586500032 DATE: September 8, 2023 INTRODUCTION The attached resolution is in reference to the public hearing 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 discovered 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 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 railroad mainline tracks, through the floodwall/levee system, into the Mississippi. 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. In addition to lining the existing culvert, the work includes 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 which will both facilitate the lining process and allow for maintenance of the culvert once complete. The City has a pending claim (ICP047008A1) into the lowa Communities Assurance Pool (ICAP) for making the permanent repairs to the culvert that will offset the City's cost to a certain extent as determined by ICAP. .i 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 PROJECT SCHEDULE The schedule for the Project is as follows: Initiate Public Bidding Process September 5, 2023 Publish Notice to Bidders, Advertise for Bids September 6, 2023 Publish Public Hearing Notice on Plans & Specs September 8, 2023 Public Hearing on Plans & Specifications September 18, 2023 Receipt of Bids (Bid Letting) September 26, 2023 Award Construction Contract October 2, 2023 Final Completion April 5, 2024 RECOMMENDATION I recommend approval of the plans, specifications, form of contract, and construction estimate of$586,000.00 for the Maus Park Lake Pump Station Culvert Repair Project. BUDGET IMPACT The Project is to be funded through a FY23 appropriation in the amount of $463,940 for Maus Park Culvert Restoration (Project 5586500032). Because the pump station and culvert were insured, the City submitted a claim (ICP047008A1) into the lowa Communities Assurance Pool (ICAP) for making the permanent repairs to the culvert that will offset the City's cost to a certain extent. If needed, additional funds will be used 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). ACTION TO BE TAKEN I respectfully request adoption of the attached resolution approving the plans, specifications, form of contract, and construction estimate of $586,000.00 for the Maus Park Lake Pump Station Culvert Repair Project through the adoption of the attached resolution.
