RE:
14 Hopetoun Avenue, Reservoir D-377-2024
I have reviewed the supplied plans of proposed works prepared by Design Matters
received 30/07/2024 and the arborist report prepared by Bluegum received
30/07/2024.
Eight trees were assessed in the provided arborist report. The tree data in the
supplied arborist report appears correct

Recommendations
The proposed removal of trees #2 and 3 does not require a permit.
Trees #1, 4, 5, 6, 7, and 8 will remain viable.
Conditions:
• Prior to the commencement of any buildings and/or works approved by this
permit, temporary fencing must be erected around any tree shown for
retention on the endorsed plans to define a Tree Protection Zone (TPZ) to the
satisfaction of the Responsible Authority and must:
Page 2 of 4
a.
Exclude access and construction activity within the TPZs assessed in the
Arborist Report by Bluegum 30/07/2024. If trees have not been assessed, the
TPZ is a circle with a radius equal to 12x the trunk diameter measured at 1.4 m
above ground level, and
b.
Have a minimum height of 1.8 metres and comply with Australian Standard AS
4687 for temporary fencing and hoardings, and
c.
Not extend beyond the site boundaries except into roadside reserve and/or
nature strip areas. Fencing within roadside reserves and/or nature strip areas
must not prevent the use of a road or footpath, and
d.
Remain in place until all buildings and/or works are completed, unless with the
prior written consent of the Responsible Authority.
Temporary fencing can be modified to accommodate encroachment into the
TPZ of the tree(s) as per the endorsed plans. Fencing must be modified in line
with the footprint of the approved works only.
• Al underground service pipes/conduits including stormwater and sewerage
must be diverted around the Tree Protection Zone (TPZ) of any retained tree,
or bored underneath with a minimum cover of 600mm to the top of
pipe/conduit from the natural ground surface to the satisfaction of the
Responsible Authority. Al pits, holes, joints, and tees associated with the
installation of services must be located outside the TPZ, or the project arborist
must demonstrate works in the TPZ wil not impact viable tree retention to the
satisfaction of the Responsible Authority.
• The paving within the Tree Protection Zones (TPZ) of Tree #5 must be
constructed above the existing grade using permeable materials to the
satisfaction of the Responsible Authority. There must be no excavation within
the TPZ, except for scraping the surface up to 30mm deep to remove surface
organics and/or debris.
• Al tree protection zones must be observed according to Australian Standard
AS4970-2009
Protection of trees on development sites. Tree protection
zones are to be shown in all plans and must be put in place before any work
occurs on-site.
Canopy tree planting
Tree planting must be conducted within the first planting season (May to September)
following the completion of the permit ed buildings and/or works to the satisfaction of
the Responsible Authority
Page 3 of 4
• Four (4) medium-sized canopy trees in the private open space of the
proposed development, with a minimum mature height of 8m. At the time of
planting these trees are to be from 50L size pots and at least 2m in height.
