The presence of the Emerald Ash Borer (EAB) was detected on several streets within the community in November 2011. This was confirmed by the Illinois Department of Agriculture. In response, the Village conducted a thorough parkway tree inventory, collecting data on the condition of all parkway ash trees. The Village then removed approximately 400 parkway ash trees which were determined to be in the poorest condition.

While some available treatment programs may delay the deterioration of tree canopies, the ash trees will ultimately need removal. Therefore, the Village has elected not to pursue a treatment program for parkway trees. Please be advised that the Village will not approve the insecticidal treatment of any parkway tree and has not approved any landscaping contractor to perform such work.

The Village’s comprehensive urban forest management plan provides for the slow and managed removal and replacement of ash trees, combined with the replanting of large replacement trees, which will allow residential neighborhoods to maintain their tree-lined character. The Village plans to systematically remove a minimum of 500 parkway ash trees annually, as determined by individual tree data, and then continue to plant new parkway trees of varying species to replace the ash trees and maintain our urban forest. The Village is very proud of its 30-year designation as a Tree City USA by the Arbor Day Foundation.
