Tree Protection in Oak Lawn, IL: What Residents Actually Need to Know

If you live in Oak Lawn or are thinking about moving there, tree protection are one of those things you probably won't think about until they affect you directly. Oak Lawn has 2 specific rules on the books covering different aspects of tree protection, and some of them might surprise you.

Protected Tree Species

When utilities install or maintain lines in Oak Lawn's public right-of-way, the Village can require extra protection for specimen trees or trees of special significance, using higher poles, side arm extensions, or covered wire instead of cutting them.

Key details: Applies to: Utility tree trimming in Village rights-of-way. Protection tools: Higher poles, side arm extensions, covered wire. Decision: Village decides case by case, discretionary. Remedy for damage: ISA-formula compensation plus permit cancellation.

Utilities that damage or remove a specimen or significant tree without authorization owe the Village compensation calculated under the International Society of Arboriculture formula, and risk permit cancellation.

Oak Lawn is more permissive than most cities when it comes to protected tree species. That said, there are still limits.

Parkway Planting

Oak Lawn bans planting ten invasive or hazardous tree species anywhere in the village, including parkways, and runs a 50/50 cost-share program for replacing parkway trees the village forester takes down.

Key details: Banned species: 10 trees, incl. willow, poplar, ash. 2008 additions: Ash, mulberry, Bradford pear (3/1/08). Replacement call: Village forester decides case by case. Cost share: 50/50 village-owner parkway tree program.

Planting a banned species violates § 9-2-1; the department of quality control can order it removed. Declining the 50/50 replacement program under § 9-2-8 carries no fine: it just means the parkway spot stays empty.

The Bottom Line

Oak Lawn's tree protection rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Oak Lawn is broadly strict or permissive.
