Tree Protection in Evanston, IL

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

Protected Tree Species

Evanston protects trees once they hit a minimum trunk diameter tied to their species-quality group: any public tree at 2 inches DBH, and any private Group A through D tree at 6 inches DBH, becomes a "Protected Tree" triggering permit and replacement rules.

Key details: Species groups: A (highest) to D (lowest). Public tree threshold: 2 inches DBH. Private tree threshold: 6 inches DBH, all groups. Multi-stem >20 ft: Trunk diameters aggregated. Penalty: $100–$1,500 per violation.

Damaging or removing a Protected Tree outside a valid tree preservation permit draws a fine of $100 to $1,500 per violation, with each day of continued violation a separate offense, under Section 7-8-8-12.

This is one of the stricter rules in Evanston's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Parkway Planting

Evanston caps what residents can plant in the street parkway: shrubs, perennials, ornamental grasses, and annuals can't mature taller than 3 feet, new parkway trees must sit 15 feet from any crosswalk, and any parkway planting needs a free Public Works permit.

Key details: Max plant height: 3 feet in parkway. Tree setback: 15 ft from crosswalks/intersections. Planting permit cost: Free. Maintenance commitment: 3 years minimum. Temp fencing allowance: One 8-week period per year.

Planting a shrub, perennial, grass, or annual over 3 feet tall in a parkway, or planting a tree within 15 feet of a crosswalk, without first obtaining a Public Works permit is unlawful under Section 7-8-4-1(A).

The Bottom Line

Evanston'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 Evanston is broadly strict or permissive.

Keep in mind that Evanston can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
