Tree Grid Update

The City’s Bureau of Forestry (BoF) follows a grid-based tree trimming system to ensure efficient and equitable maintenance of Chicago’s urban tree canopy. Crews trim all trees within a 16-block area on a designated day. Once trimmed, trees should not require additional maintenance for at least five years.

The City of Chicago uses a grid system for tree trimming with 1-2 trim crews from the Bureau of Forestry (BoF) trimming trees in a 16-block area, or "grid," on a given day of the week. BoF trims every tree in the grid, and if these trees are properly cared for, they should not need to be trimmed again for at least five years.

03/23/26 Update: See the map below for grids that overlap with the 48th Ward.

BoF is finishing up what's left of Grid N052 - W012 and started working on Grid N060 - W012.

Scheduled Tree Trim: Thursday

Weather and staff permitting this is where trimming will occur. 

48TH WARD GRID N052 - W012

Emergency Tree Trims

For immediate hazards (e.g., a tree blocking a street, sidewalk, or impacting property), call 311 or contact our office. If your tree trim is an emergency, send us photos, and we will escalate the request to BoF.

Special Requests

For non-emergency requests, please submit a Special Tree Trim Request Form. After submitting, please email info@the48thward.org if we do not reach out to you in a timely manner.

You can do your part by looking out for posted “No Parking” signs and by reminding your neighbors to do the same. We also recommend reviewing the city's claims process for trees that impact your property. To report tree emergencies (such as a fallen or hanging tree limb that is blocking the public way or obstructing traffic control measures) contact 311 or our office.
