City of Upper Arlington, Ohio

Plan & Policies

EAB Management Plan & Policies

The following elements of the City's EAB management plan have been adopted, and are subject to periodic revision as new information about the borer is available. This plan is also subject to change should state or federal policies dictate. The Upper Arlington Division of Parks & Forestry is the lead agency responsible for plan implementation. Working with the Upper Arlington Tree Commission, the Division will provide public education/information regarding EAB as a routine service, and an annual report to City Council will be prepared.

Street Trees

  1. The City is gradually removing and replacing native ashes in street rights of way. The removals began in 2006, and poor condition trees were removed first. At least 10% of ashes are being removed annually, enabling the City to phase out ashes over an eight to ten year period. All adjacent residents are notified of planned removals. 
  2. Removals are dispersed over neighborhoods to lessen sudden impact on residents, aesthetics, and property values.
  3. Requests from adjacent residents are honored when possible. This includes those who request that ashes be retained (in expectation that protective treatments will be applied by the resident). 
  4. The City does not treat street trees. Protective pesticide treatments are effective if proper dosage and timing are employed, and may be applied at residents' discretion and expense. Free permits are issued to any resident who chooses to treat street trees. Treated trees will be removed if treatments fail and EAB infests the tree.
  5. All trees that are removed are replaced. Species diversity is a planting objective to better protect our community's trees in the future. Planting occurs in spring and fall per the City's standard operating procedures.

Park Trees

  1. There are many specimen ash trees in City parks, as well as thousands of ashes in wooded park areas. No inventory of park trees exists.
  2. The City cooperates with public agencies to implement EAB policies, and with researchers when the opportunity arises.
  3. Specimen trees are being monitored. The City is removing these trees as infestation and tree decline occur. A few commemorative trees and Tree Trek featured trees are being treated to preserve them.
  4. Ash trees in wooded areas will be left alone. These trees will die, but will be left in the woods to fall and decompose unless they present a hazard, in which case they will be felled and left in the woods.
  5. Specimen ash trees are being replaced. In wooded areas, natural regeneration will play a significant role in reforesting parkland, but competing invasive/non-native plants will create challenges and may require control efforts.

Trees on Private Property

  1. There are many thousands of ash trees large and small on private property in Upper Arlington. No reliable inventory exists, and ash density varies by neighborhood.
  2. The decision to treat, remove, or retain private trees rests with the property owner. Residents should consider many variables when evaluating options, including tree size, location, and condition; access to the tree; potential targets should the tree fail; property value; shade, heating, and cooling values; treatment techniques, efficacy, and costs; and intangible values.
  3. The City will enforce the relevant sections of C.O. Chapter 907 should it receive complaints about hazardous private trees. Private trees that are a threat to the safety or property of others, or to the public right of way will be inspected as complaints are received, and condemned through removal orders when necessary. If the City is forced to perform removals on private property, owners will be billed or assessed for 150% of the City's cost per Code.
  4. It would be prudent for residents to maintain a relationship with an ISA Certified Arborist.  In the event that ash evaluation, treatment, or removal is necessary, a reliable contractor is a valuable ally. Contractors should be able to provide proof of liability insurance and worker's compensation coverage. The City also encourages residents to replace trees lost with species appropriate for the site, or to plant new trees in advance of EAB infestation and ash removal as a way of preserving the tree lined streets and beautiful neighborhoods that typify Upper Arlington.
