Ash Tree Removal / Replacement Program (ATRRP)
In 2012, the Village formalized its initial Emerald Ash Borer (EAB) efforts with the policy decision to remove and replace all parkway ash trees. The Village engaged two separate contractors.  GroundsKeeper Landscape Care, LLC was contracted to perform ash tree removal, stumping and surface restoration, while Mid-America Tree and Landscape is contracted to implement the Village’s one-for-one ash tree replacement program.  In most cases, when an ash is removed, a replacement tree will be planted in its place. There may be some areas where a one-to-one replacement is not possible due to underground infrastructure and line-of-sight concerns. The Public Works Department in coordination with our tree removal/replacement contractors developed a systematic plan of attack to remove and replace the Village’s 8,085 parkway ash trees.

The Board of Trustees expedited ash tree removals from an initial six (6) year program to a three (3) year program (2013, 2014, and 2015).  With this new timeline, all parkway ash trees will be removed by the end of 2015.  Because of the planting season limitations (spring and fall), replacement tree installations will be completed by the end of 2016.

The Village is divided into 35 working areas [see ATRRP Map].  These areas were inspected by certified Village arborists and prioritized according to the number of “priority” ash trees found in a respective area.  Priority ash trees are those that fall into the fourth category of ash trees (good, fair, poor, priority) having the following characteristics:

  Close-Up of Priority Tree    Priority tree (example)      

- Ash trees requiring immediate and high priority removal
- Ash trees having zero canopy
- Ash trees having a large number of shoots that arise below the dead portions of the tree, particularly at the tree base
- Larger dead/dying ash trees that can cause injury to persons or property
- Ash trees having zero canopy with moderate to large diameter dead branches, located in high traffic and pedestrian  areas or areas in direct proximity to property

Ash Tree Removal

To ensure that these priority trees are removed as quickly as possible, Village staff will target and remove priority trees outside of the areas where the tree removal contractor will be working. 






The Village’s contractor has completed tree removals in program areas 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 29, 30, 32, 33, and 35. We have begun tree removals in area 11. Creating “sub areas” provide flexibility in how we can monitor and guide our ash tree removal efforts based on changing factors.  For instance, sub area 35 had a healthy concentration of priority ash trees. The streets in area 35 were resurfaced during the spring of 2014. It made more sense to bring in heavy equipment to remove trees before the new street was repaved. Areas bordered by the red outline have been completed.

Ash Tree Removal/Replacement Program (ATRRP) at a Glance     
  • The Village inventoried approximately 8,085 parkway ash trees in the Village of Orland Park.
  • Village’s initial ash tree removal/replacement program was a 6-year program (2013 through 2018). 
  • In the fall of 2013, the Village Board expedited the tree removal process and funded a more aggressive three year program (2013 through 2015.)

Village arborists will continue to evaluate our Village-wide ash tree inventory to identify the next sub area that will be scheduled for ash tree removals.

Answers to Frequently asked Questions

Characteristics of the EAB

The adult Emerald Ash Borer is usually bronze or golden green in color with darker, metallic emerald green wing covers. Males are larger than females but the adult insect is generally about half the diameter of a penny.

Detection of Tree Infestation by the Emerald Ash Borer Detection of the Emerald Ash Borer infesting a tree can take up to a year before there are any signs of damage. A tree that has been infested for at least a year will have D-shaped exit holes present on the branches and the trunk left by emerging adult borers.

Prolonged infestation will cause a tree to die from the top.
