Although the green belt area between the sidewalk and the curb is usually called the right of way, and is under the jurisdiction of the City, it is the homeowner's responsibility to maintain this area.
Any trees in the green belt are the City's responsibility to maintain. The City has guidelines as to the species of trees that are planted in the green belt and the minimum distances between trees, which includes sight distance requirements at intersections and minimum distances from hydrants and streetlights.
The City does have a tree-planting program. If a homeowner does not want to wait for the next City planting, they can arrange to plant their own tree. However, the City must approve the location and tree species of any planting in the green belt before any work is completed. Contact the DPW Director at (248) 651-9061 for details.
