Attachment 6 - Arborist Statement

12. Conclusion:
The second preliminary site visit involved capturing trunk diameter measurements to map out the TPZ and
SRZ radius.

It was anticipated that a significant number of active roots would be exposed by the proposed excavation
activities at this distance from the Structural Root Zone (SRZ); however, the hand excavation conducted
on the 27th of May revealed minimal active roots within the pothole sites.

These findings confirm that the tree can be retained without damaging active roots where the driveway
alignment is closest to the SRZ on the southern side of the tree.

The two exposed surface roots on the road reserve will require a soil top-dressing cover during operational
works to create a protective barrier and prevent further damage.

Mulching and watering are essential during construction to control moisture loss and soil erosion throughout
all phases.

13. Recommendations
    •   Consider all design implementations in favour of preserving the health and vitality of the tree.

    •   Utilise sensitive earthworks methods within the TPZ to avoid damage to the branch structures and
        root system.

    •   Engage a consulting arborist to oversee the excavation works within the TPZ of the Norfolk Island
        Pine.

    •   Refer to the guidelines of Noosa Shire Council tree management principles.

    •   Facilitate the installation tree protection fencing to deter stockpiling of materials or further soil.
        disturbances within the root zone.

    •   Adhere to the development guidelines AS 4970 Protection of trees on development sites.
