Tree Trimming

The Bureau of Forestry is responsible for the management of all shade and ornamental trees growing along city streets and boulevards and which constitute approximately 520,000 trees of the estimated 4.1 million trees growing in the City of Chicago. On average the Bureau trims about 100,000 public trees annually.

The municipal trimming operations performed by the Bureau of Forestry are scheduled utilizing several approaches:  Request Trimming, Crises Trimming and Programmed Trimming. All residents are encouraged to call the 311 City Services System or click on the button below to report any tree maintenance needs such as the removal of storm or construction related damaged limbs, low hanging branches, or to clear obscured streetlights and stop signs.

Currently, Request Trimming constitutes over 3/4 of all the tree trimmed annually and is scheduled as a result of calls placed to the 311 City Service System. These calls are serviced on a first come first served basis. Crisis trimming results from calls that are reporting hazardous conditions such as broken and hanging branches to the city's 311 system. These calls are responded to on an emergency basis. Programmed Trimming is the servicing of all trees requiring attention within a given area such as a city block or a 1/4 mile grid. As time allows the Bureau works with elected officials as well as community groups to designate the assigned area.
