TL;DR
A tree protection zone is the fenced-off area around a retained tree's trunk where excavation, vehicle traffic, material storage, and grade changes are prohibited during construction. Its radius is set from trunk diameter, commonly one foot per inch of diameter at breast height, or from the dripline, whichever an ordinance or arborist specifies.
What it means
A tree protection zone is the fenced-off area around a retained tree's trunk where excavation, vehicle traffic, material storage, and grade changes are prohibited during construction. Its radius is set from trunk diameter, commonly one foot per inch of diameter at breast height, or from the dripline, whichever an ordinance or arborist specifies. The fencing must stand before sitework starts and stay through completion, because the fine feeder roots being protected live in the top foot of soil and die quietly under a single season of compaction.
