After conducting a thorough tree inventory in the fall of 2012, the Village of Tinley Park was able to determine that of the 11,000 ash trees on public property, most had become infested with the destructive Emerald Ash Borer beetle.
In the winter of 2012-13, Homer Tree Care in Lockport removed about 200 dead ash trees that were deemed most unsafe. Meanwhile, the Village also responded to a number of requests to remove dangerous limbs and addressed other trees that required a rapid response.
In the spring of 2013, the Village contracted Kinnucan Tree and Landscaping in Lake Bluff to administer insecticidal injections to nearly 600 of these trees in an effort to protect them from further damage. In the spring of 2015, ash trees that responded well to the initial treatment received another round of injections. Those that did not respond well were added to the list of removals handled by Homer Tree Care. By the end of 2014, Homer finished the process of completely removing the nearly 10,000 remaining ash trees that were susceptible to the beetle. The scale of this ash removal project cannot be overstated, as it is believed to be the largest ever in the state of Illinois completed in a single phase.
All of the tree removal, stump removal and site restoration work was completed by December 2014. If you are aware of a location with a standing ash tree scheduled for removal, a remaining stump from a removed ash tree, or a pile of wood chip grindings that needs to be restored, please contact our Public Works office at (708) 444-5500.
