The city kicked off Pothole Palooza on Monday, a campaign where the Seattle Department of Transportation will be aggressively making pothole repairs based on resident reports.

SDOT’s “Pothole Rangers” will make repairs in neighborhoods where reports have been mapped out.

Potholes are caused by water and vehicle traffic, and exacerbated during winter months, when water gets into holes, freezes and expands, then thaws and contracts, according to SDOT. The transportation department states “an extremely wet and cold” winter and spring has caused an increase in the number of potholes around the city.

“We recognize that residents have been patient through a tough winter that’s resulted in an increased number of potholes and we want them to know that we’re listening when they report them,” said SDOT director Scott Kubly in a news release. “You’ve told us where they are, and we are marshaling our resources to fill them.”

People can report potholes to the Pothole and Street Repair hotline at 206-386-1218, or by using the city’s Find It Fix It app.
