Work on Dubuque Flood Gates can continue

Following a review of the hydraulic modeling and water sampling results, the Iowa Department of Natural Resources (IDNR) has determined that they will not need further environmental analysis and approved the permit needed for continuation of construction of the Dubuque Flood Gate Replacement and Pump Station Project at the 16th Street Detention Basin. The project had been paused approximately three months while additional environmental studies were conducted to determine if contaminants from a nearby fertilizer spill in 2020 would be drawn towards the project site during dewatering operations as part of the construction of the pumping facility. Following a review, the agency approved the project’s application for 10 dewatering wells to facilitate construction. Work on the site is expected to resume soon. Related lane closures/detours on Kerper Blvd. will be reinstated when needed to facilitate work at the site. The $28.2 million project is the next major phase of the Bee Branch Watershed Flood Mitigation Project.
