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 occurance 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.

A loader pours crushed asphalt into the Asphalt Recycler, which  heats and churns it to create the “hot mix.”
