Arboricultural Impact Assessment - Palm Lakes Resort Cooroy - Revision 1 - IAS17818 - 22 August 2025



setback to mitigate fisk risk. Should there be any conjecture engage a bushfire expert to determine BAL
and subsequent risk.

Further visual tree assessment was undertaken along the resort boundary proper to assess tree species
based on health, form and risk. Select trees have been nominated for removal. Ensure relevant
authority approvals are in place prior to facilitating removal. Given the current vegetation densities
along the rear property boundary it is further recommended any offsets are undertaken with
groundcover, shrubs and understorey native endemic plantings only.


Conclusion
For all retained trees, with due care, implementation of appropriate work methodology as noted in this
report and isolation of all TPZs of retained trees from construction works, the potential for ill-effect to
retained/affected trees can be minimised in accordance with guidelines of AS4970:2025 – Protection of
trees on development sites.

The following must occur:

All required regulatory approvals must be in place prior to the commencement of any tree work for
future construction work. Approvals are required should the Project Arborist prescribe pruning such as
crown clean, canopy lift and/or directional pruning.


    •    Project Arborist must be appointed and engaged to guide the protection of protected trees from
         project commencement, i.e. during Design Planning and during the construction period until its
         completion.
    •    All Arboricultural reports, TPP, TPS, VMPs & approvals must be included in the CMP
    •    Exploratory low pressure water excavation is to be undertaken as specified.
    •    Arborist briefing of all engaged persons on their commencement as well as diligent work practice
         must occur during all approved future construction work.
    •    Root disturbance must be minimised to prevent accidental injury, compression and the creation
         of exposure points to allow future entry of pests and pathogens.
    •    All work within any TPZ must be supervised by the Project Arborist.


All work within TPZs must be carried out with due care to avoid mechanical impact with retained tree/s
during the construction phase. Sleeving should be installed to provide an impervious barrier between
exposed TPZ perimeter/s and new concreted areas to prevent chemical leeching into the surrounding
soil of retained trees.

Reactionary processes, such as the emergence of deadwood, dieback etc. are likely to occur as a result
of disturbance and/or injury to any retained tree on a construction site. Amended design plans and
construction methodology can serve to avoid or minimise the likely emergence of such issues and
therefore their associated future OH&S issues to the future occupants of the new dwellings and or
pedestrian or vehicular traffic within the vicinity of retained tree/s. Any required pruning is to be
undertaken by a minimum AQF Level 3 Arborist under the supervision of the Project Arborist (AQF Level
5).
