Naperville protects its urban forest through Title 9, Chapter 3 (Urban Forest Protection) and Title 5, Chapter 10 (Landscape, Screening and Tree Preservation). While the city does not use the term 'heritage trees' formally, large trees on properties over 1.5 acres and all non-residential parcels receive protection through the tree removal permit process.
Naperville's Urban Forest Protection ordinance (Title 9, Chapter 3) and the Landscape, Screening and Tree Preservation provisions (Title 5, Chapter 10) establish the framework for tree protection. The city does not have a formal 'heritage tree' or 'landmark tree' registry, but significant trees are protected through the permit process. A tree removal permit is required for any tree 4 inches or greater in diameter (measured at 4.5 feet above ground, known as DBH) on residential lots greater than 1.5 acres and on all non-residential parcels. Residential lots under 1.5 acres are exempt from the tree removal permit requirement. The City's Department of Public Works manages the urban forest and reviews tree removal applications through the Civic Access Portal. Parkway trees (those between the sidewalk and street) are owned and maintained exclusively by the city; only the Department of Public Works may remove them. Construction projects must incorporate tree preservation plans to protect trees designated for retention.
Unauthorized tree removal on applicable properties: fines and potential replacement requirements assessed by the Department of Public Works. Damage to parkway trees: city may assess replacement costs.
