How is a Pothole Formed?
Potholes are mainly caused by freeze-thaw cycles from February to April. During warmer days, road surfaces thaw, allowing water to seep into cracks. When temperatures drop again, the water freezes, expands, and cracks the pavement, creating potholes.
In Ramsey, about half the streets were built between 1975 and 1985 and are nearing or past their useful life, needing replacement sooner than 30 years. The City stopped seal coating streets in 2019 due to observed damage from multiple treatments. Winter 2023 was particularly wet, with many freeze-thaw cycles further deteriorating these streets.
