Protected trees
Grand tree: any tree 24 inches or greater D.B.H. (measured at 4.5 feet above grade), excluding pine trees and sweet gums. Protected tree: any tree 8 inches D.B.H. or greater, except multi-stem crepe myrtles. Commercial lots, lots with three or more dwelling units, and residential lots of one acre or more must keep 15 Protected trees per acre; if they do, no permit is required. Trees in the OCRM critical line buffer may not be removed. On Daniel Island, removing any tree 8 inches or larger D.B.H. in the Visual Buffer Zone needs Board of Zoning Appeals - Site Design approval when certain conditions are met.
