                 Tree Protection Zone (TPZ)
                 A TPZ is determined by setbacks calculated for each tree based on its age class, vigour class and crown spread (where
                 necessary) and each tree fenced off to form an enclosure around the tree with the tree at its centre, or may utilise an existing
                 structure being retained such as a wall of fence.

                 The TPZ should be secured by a lockable gate to restrict access and the area identified with signage. The area of the TPZ
                 should be mulched except where turfed and kept free of weeds. Where encroachment is required within the TPZ this should
                 be done only with the approval of the project arborist.

                 Signage

                 Signs identifying the TPZ should be placed around the edge of the TPZ and be visible from within the development site. The
                 lettering on the sign should comply with AS 1319.
