 Arborist comment                 Adam Demler 05/09/2025: The design proposed
                                  a major encroachment due to works being inside
                                  the SRZ. Inside the property, fill is being used to
                                  match FSLs to the garage. Minor (up to 100mm) of
                                  excavation is required within the Council
                                  easement to allow for FSLs to match current levels.
                                  The above-ground root buttress of Tree 2 has a
                                  diameter of approximately 160 cm.
                                  A hand-dug trench measuring 3 m × 0.1 m × 0.1
                                  m was excavated 1 metre from the outer edge of
                                  the trunk, oriented perpendicular to the kerb.
                                  Within this trench, only fine roots were
                                  encountered, along with two structural roots that
                                  were successfully traced back to the root collar of
                                  Tree 2.
                                  A second trench of (of similar dimensions) was
                                  excavated adjacent to the existing brick wall. No
                                  significant roots were identified in this location;
                                  however, displacement of the wall suggests the
                                  presence of roots exerting pressure from below.
                                  Both investigations indicate that the tree’s root
                                  system is likely to be growing in a downward
                                  trajectory, consistent with typical behaviour in
                                  sandy soils. This deep-rooting tendency will
                                  reduce the likelihood of surface-level root conflict
                                  with the proposed VXO and therefore is unlikely to
                                  cause any longer-term adverse impacts to the
                                  health or structure of the tree.
                                  In conclusion, if the TPS is adhered to while
                                  undertaking the proposed works the trees health
                                  and structure will not be significantly impacted.
