Property Photos
Observations
These trees are growing in a confined space and in a sand medium which is nutrient
deprived and does not retain water especially this close to sea level. The identified
trees are within the neighbouring property. Because there is restricted aerial space
due to the building height and because of this the growth habit of these trees has
been phototrophically distorted.
In response to these conditions the root systems must expand accordingly to counter
the leverage of the trunk and canopy.
Because of the nutrient deficient ground coupled with the adventitious nature of all
species identified they will search all avenues of nutrient as evident within the carpark
and along the area with the extensive root incursions.
There is clear risk to property and clear evidence as shown in the property photos and
as such these needs to mitigate; I have developed a clear and proven method for root
incursion and will protect the property and still considers the tree health of the
identified trees.

Property and Tree Protection Methodology
We recommend is to install a physical root barrier to between 600mm to 1200mm in
depth and for the extent of the defined space ( approx 60m ).
This would involve vacume excavation approximatly 1 m from the toe of the building .
Because of the unknown depth of the root profile , we would take a cross section and
customise the depth so ans to ensure true protection of the building.
Once trenched and prior to to root barrier instalation we recommend the addition of
Bentonite Clay which is a root ihibitor and discourages root growth also as an added
barrier
Tree Protection Methodology
All tree protection is as identified in AS4970-2009 and in accordance with AS4973 -
2007 and all works to be supervised by Level 5 Arborist in conjunction with Arboreal.
1. All excavation to be done by vacuum excavation.
2. All root pruning to be done by cleaned silky saw.
3. Trench to be backfilled after the root barrier and Bentonite Clay installation with
mature forest mulch.
4. Will need a dial before you dig prior to commencing works.
