RFI - Attachment 3 - Arborcultural Impact Assessment Report · 132003.221108.3

4 Discussion
The proposed development at 27 Bayview Road, Noosa Heads involves renewal of the existing
crossover, associated demolition and construction works. Based on the current design, the location
of retained vegetation and the expectation that root development does not correlate to the calculated
NRZ due to existing constraints, the overall level of arboricultural impact is expected to be minor,
provided all recommended tree protection measures are implemented and the works proceed under
the supervision of the Project Arborist (PA).

The demolition and reconstruction of the crossover occur largely within the footprint of the existing
structure, meaning no new encroachments are anticipated for Trees 1 and 2. The only additional
encroachment relates to Tree 3, where a small portion of the proposed works extends marginally
closer to the tree. Tree 3 is positioned below the existing driveway level on a rocky embankment,
and the site’s topography strongly suggests that most of the structural root development is oriented
downslope, away from the proposed works. As such, any root material encountered is likely to be
limited in size and functional significance.

Should root pruning be required, it will be undertaken under PA supervision, ensuring cuts are
made to appropriate standards and that root loss is minimised. Given the resilient nature of the
species, the anticipated level of disturbance is unlikely to compromise tree stability or long-term
health. While post-works plant health remediation may be recommended depending on the extent
and condition of any roots exposed during construction, the need for such intervention is considered
unlikely based on current site conditions.


5 Conclusion
Overall, it is expected the proposed works can be completed with low arboricultural risk, and
retained trees are expected to remain viable provided the prescribed protection measures and
supervision requirements are followed.
