Davenport Public Works crews are preparing to close River Drive on Thursday in anticipation of rising floodwaters that threaten several downtown businesses.

Three primary teams are in the process of protecting the LeClaire Park bandshell, Modern Woodmen Park and Credit Island Lodge. The flood fighting is putting to use the city’s Hesco barrier system, which saves considerable time and effort in sandbagging.

Public Works Director Mike Clarke said the city’s current plan is to protect River Drive with the barrier system, placing the height at 21 feet, even though the current predicted crest is below 19 feet.

At Credit Island Lodge, which experiences considerable winds off the Mississippi River, the protection will reach 22 feet, Clarke said.

“I don’t get a second chance at Credit Island,” he said of protection preparations. “Once that water comes up, the only way to get back there is by fire boat.”

He said the Iowa Department of Natural Resources also is keeping an eye on area streams and creeks, including Duck Creek. If flash flooding becomes a threat, he said, the city will activate its “robo-calling system” to warn residents along Duck Creek to take precautions.

It is possible, Clarke said, the National Weather Service’s predicted 18.9-foot crest (flood stage is 15 feet) could climb, depending on rainfall in the Quad-Cities and upriver.
