Parkway tree trimming is scheduled for early January to mid-March, weather permitting. Trees will be trimmed between Chicago Avenue and Division Street from East Avenue to Harlem Avenue, and between Division Street and North Avenue from Austin Boulevard to Harlem Avenue. Village crews will prune parkway trees up to 10 inches in diameter, while Winkler Tree Service, working under Forestry Division supervision, will prune larger trees. About 4,500 trees are scheduled to be trimmed. For more information about tree pruning, replacement and removal, or questions about general tree health, call 708.358.5700 or email publicworks@oak-park.us.
