TREE TRIMMING PROGRAM
The Parkway Tree Trimming Program is conducted during each winter season on a revolving basis in designated areas throughout Lisle. Village crews will mark trees that need to be removed with a red “X”. Trees marked with a green dot will be trimmed contractually.

Trees that are on private property and overhang the right-of-way will also be trimmed to maintain height clearances of 15 feet over streets and 10 feet over sidewalks and driveways.
