Monday, they held a news conference next to the temporary floodwall along River Drive from Iowa to Perry streets.
Mayor Mike Matson says the city learned its lesson from the record flood of 2019.
"Anticipating a big flood, we'll see where it goes. But as you see we're ready. We rehearsed, we pre-positioned, we practiced and set this wall up in two and-a-half days. And then the pumps are in place, the Corps is with us, the EMA's with us, we're all ready to go."
The main difference is the floodwall is higher and wider than the one that failed four years ago. The base is two Hesco Barriers wide with one more set of barriers on top.
Public Works Director Nicole Gleason says the new and improved floodwall cost more in labor and materials, but should hold back the river.
"With the current set up I am very confident. The one thing you can't be confident in is the rain. So just as long as the rain comes in as forecasted I feel very highly confident in the setup."
In the Quad Cities the river is already several feet over flood stage and the current prediction is for a crest 6 to 8 feet over flood stage by next week. In 2019, the record flood level was 7.7 feet over flood stage.
