Weed Control Spraying on Flood Control System
Assistant Public Works Director
June 4, 2021 - For Immediate Release
DUBUQUE, Iowa – As weather permits starting Monday, June 6, the City of Dubuque Public Works Department will spray weed control in the clean stone areas in various locations, starting at the north end of the system, on the land side of Dubuque’s flood control system (U.S. Senator John C. Culver Floodwall).
The work is being done in accordance to 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. The project is expected to be completed by Wednesday, June 16, weather permitting. 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.
The U.S. Senator John C. Culver Floodwall is inspected twice annually; once
by the U.S. Army Corps of Engineers and the City's public works department and once by the City’s public works department only, which oversees floodwall operations. The City performs required maintenance on the floodwall every year, including repair of rip-rap sections, removal of vegetation, and repair of damage caused by rodent burrows.
