Dubuque to Start Weed Control Spraying on Floodwall June 29th

Starting Monday, June 29, the City of Dubuque Public Works Department will spray weed control in various areas of clean stone and rip-rap on Dubuque’s flood control system (U.S. Senator John C. Culver Floodwall), weather permitting.

Sprayers will start on the area of clean stone on the land side of the levee south of the lock and dam and continue to work south. They will then move to the rip-rap on the river side.

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. With no weather delays, the land side of the levee is expected to be completed by Thursday, July 2. The rip-rap on the river side is expected to be completed by Friday, July 31. 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.
