Tree Removal and Trimming in Northbrook, IL

Frontage, rather than preference, decides how many trees stand in front of a Northbrook house. Section 25-50 requires “one parkway tree for each 45 lineal feet of frontage.” Public works plants them “equidistant between the street curb and sidewalk.” A fee-in-lieu covers sites where planting will not work. Measure the frontage and the village’s expectation falls out of the arithmetic. That is a different starting point from the one most tree removal Northbrook inquiries open with. Most people ask first whether they may take a tree down at all.

Chapter 25 And The Six-Inch Threshold

The chapter carries the title “Tree Protection and Preservation, Vegetation.” Article II covers tree permits at Sections 25-20 to 25-26. Article III covers parkway and public trees at 25-50 to 25-52. Section 25-20(a) is the gate: “no person or governmental entity shall commence any regulated tree activity without first obtaining a tree permit from the village.” Note that it binds governmental entities too.

Protection starts at trees “with a DBH equal to or greater than six (6) inches or having an aggregate diameter equal to or greater than twelve (12) inches.” Regulated activity then covers a broad set of work. It includes damage to or removal of protected, heritage or landmark trees on the property or immediately adjacent to it. It also reaches subdivision, construction and demolition permits involving grade changes, plus special permits and site plan review. One further provision catches large-lot owners out: “removal of 20% or more of total DBH of trees on parcels 1.5+ acres within 365 days.” That is a rolling annual cap, not a per-job rule. Three modest removals across a year can add up to a permit. Keep a dated note of every tree removal Northbrook has seen on a large parcel. The village counts backward from today.

What Tree Removal Northbrook Requires You To Put Back

An owner or their representative may prune without a permit, so long as the work complies “with the National Pruning Standards.” The village may also waive requirements where “a tree emergency exists” — tornado, windstorm and the like. Replacement works by aggregate. The caliper of the new trees must equal or exceed the DBH that came out. A minimum of 2½-inch caliper applies. The applicant then handles care, watering and feeding for two years. The Morton Arboretum is the sensible place to check what will still suit the site in thirty years. Section 25-51 bars planting in the parkway without the public works director’s approval. Under 25-52, an overhanging tree that impedes traffic becomes a nuisance. The abutting owner has ten days from notice to deal with it. Otherwise the village abates and bills. The retrievable text does not give dollar fines.

Fifteen Thousand Trees, Insured For $47 Million

The village puts its public inventory at “more than 15,300 trees on parkways and village property with a combined insured value of approximately $47 million.” Parkway trimming happens in the dormant season, “approximately between October and April.” Crews rotate subdivision by subdivision — Huntington, Sutton Point, Wildebrook and the rest.

The village incorporated in 1901 as Shermerville and took the name Northbrook in 1923. It farmed on far longer than its neighbors. Records show 3,319 residents in 1950 and 30,735 by 1980. The last working farm, Wayside Farm, gave way to development only in 1987. That late build-out shows in the canopy. An unusual amount of it is old hedgerow and farmstead stock that subdivisions grew around. It stands alongside trees the 1960s and 70s put in.

The West Fork of the North Branch of the Chicago River runs through the village. Lake Shermerville and the 113.82 acres of Techny Prairie Park sit here too. Northbrook moved from CRS Class 7 to Class 6 in 2021. We could not retrieve floodplain acreage or repetitive-loss counts for the village, so we are not going to state any.
