Chicago's new tree trim strategy produces big results

CHICAGO (WLS) -- A $15 million overhaul of Chicago's tree trimming system appears to be paying off.

A review of trimming data by the Illinois Answers Project shows annual trims are up 118 percent.

Directing crews to work tree-by-tree and block-by-block instead of crisscrossing the city to chase complaints has unlocked efficiencies few thought possible, officials said. Trees that had become dangerous over more than a decade of neglect are now getting attention from arborists. The overhaul has set the city's tree canopy on pace for a potential top-to-bottom refresh by 2030. Department leaders hope that will mean less damage to cars and homes, fewer trees felled by disease and damage - and a sharp drop in complaints to ward offices.

But the system comes with complaints from some alderpeople who now have less control over trimming services. You can read more about the tree trimming overhaul at illinoisanswers.org.
