City to Start Weed Control Spraying on Floodwall

July 18, 2023 -- For Immediate Release

Starting Tuesday, July 18, the City of Dubuque Public Works Department will spray weed control in various areas on the land side and rip-rap 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 areas being sprayed. With no weather delays, the work is expected to be completed by Friday July 21. 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.
