The City has 1,350 lane miles of streets to maintain, so calls from our community members in pinpointing new potholes are always welcome and appreciated.
Potholes can occur any time during the year but tend to occur most often during and after the winter season, especially when there is a lot of precipitation and changing temperatures. Pavement expands and contracts during extreme hot and cold spells. This allows water to get under the pavement and leads to potholes. Snow plows and heavy traffic can also increase the occurence of potholes. Street Division crews work year round to patch potholes, including during the winter when they aren’t driving snow plows, but especially when pavement temperatures are above freezing and not wet.
To report a pothole, please call the City of Columbia Contact Center with a specific location. Your report will be logged and sent to Public Works Street Division for response.

Hot Mix Process
Here’s how the pothole repair process works.
1 A loader pours crushed asphalt into the Asphalt Recycler, which
heats and churns it to create the “hot mix.”
2 The loader takes the hotmix from the recycler …
3 … and dumps it into a mobile Hotbox that keeps the asphalt
at 350 degrees throughout the pothole patching process.
(The hot box has a heating element that runs on propane.)
4 Crews pull the Hotbox throughout the city, patching potholes
with steaming hot mix as they go. Once a pothole has been spotted or reported, it’s the goal of Public Works to repair it as soon as possible (preferably within 24 hours), weather and resources permitting.
