5 Conclusions

5.1 Condition No 16
Given the extensive nature of the bulk earthworks across the majority of the
site, the overall age/poor health and structure of the Melaleucas on the site,
retention of any trees outside of the building footprints isn’t possible for a
long-term health and structural arboricultural perspective.

5.2. Condition No 17
The requirement to install sheet piling outside of the building located in the
south-eastern comer of the site will impact heavily on Trees No 1, 2, 3 and 4.
Tree No 1 has a poor retention value due to the basal structural defect and poor
useful life expectancy, where as Trees No 2, 3 and 4 will be severely impacted
by the sheet piling. Combined with their overall small stature, therefore
lacking significance when compared to larger trees, removal and replacement
of all 4 trees is the best option and will increase the future treescape of the
nature strip and site.

Tree No S is neither in good health or structure, therefore removal and
replacement with a superior specimen at the landscape phase is the best option.

Tree No 6 has a short useful life expectancy due to the loss of a major first
order branch, including a major future structural issue, therefore the retention
value is low and removal is recommended.

Trees No 7, 8 and 9 are also poor specimens for retention. This is due to their
advanced age and prevalence of the decay fungus Phellinus throughout their
branch structure. The client requests and prefers the retention of these trees,
and given the driveway footprint, retention maybe possible under supervision
of a qualified sit arborist and as per AS4970-2009.

i] Condition No 49
Assessment of the KHMP by James Warren and Associates found no trees
specified for retention due to Koala activities, therefore the requirements of
this condition aren’t applicable.

5.4 Tree Protection (Western Reserve)
Although not addressed under the conditions of DA consent, the trees and
vegetation located on the western side of the gabion wall are retainable (no
obvious impacts or future targets in their vicinity). Protection of the
vegetation and trees maybe done by installation of appropriate fencing and
signage with the assumed erosion control measures placed on the western side
of the gabion wall during construction.
