Since 1992, the Village of Lisle has been recognized as a Tree City USA by the National Arbor Day Foundation. This award recognizes communities that effectively manage their public tree resources, and meet the standards that are set by the National Arbor Day Foundation, the USDA Forest Service, and the National Association of State Foresters. As part of these standards, the Village has a Tree Commission and an annual Arbor Day Celebration in April.
The Village maintains over 6,000 parkway trees. The Parkway Tree Trimming Program is conducted during each winter season on a revolving basis. 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.
The Village of Lisle has planted more than 140 species of trees on Village property. The Parkway Tree Planting Program provides trees for parkways that are directly adjacent to Village roads. Unfortunately, trees cannot be planted in areas where the Village of Lisle has inadequate right of way behind the curb. Arboretum Woods and some areas within Green Trails have no right-of-way behind the curb.
The Village plants approximately 30 trees each year on public property along streets. The trees are used for:
Replacing trees previously removed
Filling in areas without trees along streets where there are no houses
2017 Parkway Tree Options
In the spring of 2017, the Village will plant new parkway trees in certain areas where sufficient space is available for a new tree. Property owners who are eligible to receive a new parkway tree will receive a letter asking them to submit their top three choices of trees from options listed in the 2017 Parkway Tree Options Guide to the Village of Lisle Forestry Department. Not all removed trees will be replaced if there is not enough space for a new tree or other negative factors exist. The Village will do its best to honor your top choice, but tree quantities are limited. If you received a letter, please submit your tree choices by March 3, 2017.
Things to Remember about Tree Care
Trees need to be taken care of even though many survive with minimal care. Important tree care tips:
Trees need deep root watering and occasional fertilizing
To prevent damage, do not run mowers against tree trunks
Place a mulch ring around the trunk to help tree retain moisture
The mulch ring should be kept level with the surrounding ground
Trees should be professionally trimmed every 5 to 7 years to thin the crown and remove dead branches
