Mosman Tree Management Conditions

39. To limit the potential for damage to the tree/s to be retained, tree protection measures are to be installed in accordance with "Australian Standard 4970 Protection of Trees on Development Sites" prior to the commencement of site works, in accordance with the following: (a) No construction or excavation (including trenching for drainage or other services) shall occur within the Structural Root Zone (SRZ) of any retained and protected tree. Protective fencing at a minimum 1.8 metres in height along the perimeter of the Tree Protection Zone (TPZ) (outside of approved works) is to be installed. The TPZ is to be identified by signage placed around the edge of the TPZ which is visible from…

70. The applicant must engage a suitably qualified and experienced aborist (Australian Qualification Framework level 5 or above) to assess the impact of the proposed works and employ best practices (e.g. minimise compaction, soil build up and/or excavation within tree protection zones *) to ensure the longevity of trees to be retained/the trees specified below. The arborist is to attend on site during critical stages of excavation and construction works within the vicinity of trees to be retained and is to photograph and record the following information: • the date and time of inspection; • the methods of excavation or construction used to carry out works; • any damage sustained by the…

52. To minimise disturbance to all retained tree identified in Tree Impact Plan prepared by Context rev 4 dated 3.09.2025, no excavation shall take place within the structural root zone, measured as a radius from the trunk of the tree. Excavation may occur between the structural root zone and tree protection zone but only by hand under the supervision of an Australia Qualification Framework level 5 arborist. In the event that major structural or feeder roots (>50mm diameter) are encountered within the tree protection zone, the site arborist is to recommend and/or implement appropriate measures to ensure the retention of the tree/s. If these measures involve structural alterations to the…

51. All natural landscape features including trees and other vegetation, natural rock outcrops, soil and watercourses shall remain undisturbed except where affected by necessary works detailed on approved plans. To minimise impacts upon trees to be retained, no permanent fill or storage of building materials, excavated fill or topsoil during site works shall take place within their driplines.
