City of Lake Forest, IL

In December, both the City's contractor and ComEd will be pruning and trimming trees in Lake Forest. Here's what to expect.

Contractual Tree Trimming

Tree pruning is one of the most important components of maintaining a healthy urban forest. Pruning removes dead and/or competing branches to encourage healthy new growth and maturation. It also removes and reduces weak branches that can become a safety hazard. The process maximizes a tree’s value and maintains numerous environmental and community benefits.

While City crews prune trees on parkways and in public areas throughout the winter, the City uses a contractor to do additional pruning in order to accomplish more during the time of year when it's best to prune trees.

What to expect:

• Contractor: Advanced Tree Care
• When: December 2022
• Pruning specifications:  Standard Class 2 – Remove all dead, dying, diseased, interfering branches, located in the canopy that are one (1) inch in diameter or greater. Raise the canopy to a minimum of fourteen feet above the road and eight feet over the sidewalk. Pruning shall be conducted in a manner that maintains the crown shape and symmetry typical of the species being pruned.
• Where: View the Pruning Map for locations.

If you have any questions, please contact the Forestry Section at (847) 810-3564.

ComEd Tree Trimming and Vegetation Management
Trees and branches that interfere with power lines can create safety hazards and cause power outages. Preventative tree maintenance helps avoid power outages.

• Within the next 3 months, ComEd will trim trees, branches and vines that interfere or have the potential to interfere with power lines.
• In some cases, tree removal may be required. The remaining tree stumps are treated with an approved herbicide to prevent future regrowth. Herbicide will be applied by state-licensed applicators.
• All work is performed by trained, qualified arborists.
