The flood gate replacement and pump station project at the 16th Street detention basin is being forced pause.
Dubuque city officials say the Iowa DNR is ordering the pause following concerns about contamination due to a fertilizer spill at Gavilon Grain in 2020.
The DNR says the city needs to conduct further environmental studies before construction can resume. The City has hired HDR Engineering and Terracon Consultants to expedite these studies at a cost of nearly $240-thousand coming from the project’s contingency budget.
The $28-million dollar project is the next major phase of the Bee Branch Watershed Flood Mitigation Project.
