Tree Assessment

Overview

One of the primary concerns in Elgin is public safety. Tree removal and pruning projects are a vital part of risk reduction in the city and our neighborhoods. Almost 95% of the public trees in Elgin are in good to fair condition; however, there are large trees that are dead or have serious defects that threaten the safety of our streets, sidewalks, parks, homes, businesses, and the people who use them.

What is a "risk tree?"

The recent citywide public tree assessment revealed where high-risk trees are located and prioritized the maintenance work needed to correct or eliminate the risk. A 'risk tree' is defined as an entire tree or defective tree part that poses a high risk upon its failure or fracture to cause injury to people or damage property. A tree is not considered a high risk unless there is a nearby target that it could injure or damage. A target could be a person, vehicle, building, recreational area, or any area where people or vehicles are likely to be, stop, or congregate. By definition then, a risk tree = a defective part + a target + high probability of failure.

How is a risk tree determined?

To determine the severity of risk and the probability of failure, Certified Arborists carefully assess each tree and make note of: the size, species, and overall condition of the tree; cracks, splits, or other defects in the roots, trunk, and branches; and the presence of targets and frequency of use of the area.

If a tree is removed, will another one be planted?

Every effort will be made to replace a tree that is removed. A tree will be replaced if the abutting property owner requests a replacement tree, if the location is suitable for a new tree, and if sufficient funding is available.
