City to Start Weed Control Spray on Floodwall

Aug. 4, 2023 -- For Immediate Release

Starting Monday, Aug. 7, the City of Dubuque Public Works Department will be spraying weed control in various areas on the land side and rip-rap areas on the river side of Dubuque’s flood control system (U.S. Senator John C. Culver Floodwall), weather permitting.

The work is being done in accordance with the United States Army Corps of Engineers Engineering Technical Letter (110-2-583) which requires the removal of unacceptable growth within the “Vegetation-Free Zone.” The requirement applies to all vegetation except grass along the flood control system. Signs along the flood control system will identify the area being sprayed. 

With no weather delays, the work is expected to be completed by Thursday, Aug. 10. The Public Works Department cautions people to keep their children and pets out of direct contact with the sprayed weeds for 24 hours after application.
