Many municipalities in Pennsylvania have ordinances regarding planting, care and removal of trees. Your municipality may also have a shade tree commission that oversees the trees within the right of way (ROW) and parks. Some ordinances may require a permit while others prohibit all trees or trees of certain species from being planted in some areas. If you are working on planting, pruning or removing a street tree in your municipality, check your local ordinances before you get started.
The City of Pittsburgh has municipal code that protects trees, allows for the creation of the Pittsburgh Shade Tree Commission, and requires developers to plant trees as part of new construction. The Pittsburgh Shade Tree Commission has convened a committee that is currently working on reviewing and updating the City’s code that affects trees.
