The City of Evanston’s Public Works Agency has announced its 2022 alley maintenance schedule.
Each year, starting in the spring, Evanston’s more than 300 unpaved alleys are periodically graded by the city. This work is done to eliminate potholes and ruts caused by vehicles, weather and other factors. The process improves travel and reduces puddling.
To find out when an alley zone is next scheduled to be graded, weather permitting, community members are encouraged to view the 2022 Alley Maintenance Schedule at cityofevanston.org/alleymaintenance, or call/text 847-448-4311. For convenience, residents may simply dial 3-1-1 in Evanston.

I hate it when the city does this. It makes so much dust/dirt air pollution!
