Curbs are designed for drainage. It's unusual for there to be a problem, as most curbs are fine and drain properly. Generally, if a curb needs to be replaced it's because it has shifted, broken or doesn’t drain properly. In order to stay on-budget, the Village must follow its procedure and stay within the guidelines for replacement (and not replace simply for aesthetic reasons).
The Village places the most importance on curbs that have excessive damage/cracking, as well as locations where water sits in the curbline due to an insufficient slope in the curbline.
Your curb may not meet the criteria for removal and therefore wasn't approved for replacement. Please call the Romeoville Public Works Department at (815) 886-1870 for more information.
