Any requests for curb and sidewalk replacement should be directed to the Engineering Division at (319) 286-5802. A list of deficient curbs and walks is prepared annually to be awarded to private contractors for replacement. Depending on the severity a temporary asphalt patch will be installed by the Street Program or if weather and resources permit a small portable milling unit will be dispatched to grind off any tripping hazards on sidewalks until permanent repairs can be made.
