Full Breakdown
Under the Maintenance & Removal of Trees section of Dayton R.C.G.O. § 150.800.6, all planting and pruning of trees within the street right-of-way must follow the American National Standards Institute's ANSI A300 Pruning and Planting standards. The code separately prohibits 'topping', cutting large branches from a tree's crown, as a method of pruning or controlling growth, and bars installing tree grates or other grating flush with the pavement around a street tree. Owners must also maintain newly planted street trees for two years and replace any that die in that guarantee period.
Violations & Fines
Topping a street tree, pruning outside ANSI A300 standards, or installing flush tree grates around a right-of-way tree violates § 150.800.6 and can require corrective replanting or restoration at the owner's expense.
