Arborist Further Advice Response Letter

I NFORMATION R EQUEST
Noosa Council has requested additional information on two points relating to existing trees
located on the council road verge adjacent to the property at 2 Arakoon Crescent.

Details of each tree were focused upon within the submitted Arboricultural Impact Assessment
report. 23_02_22_AIA_Adapt_2 Arakoon_2



Request details provided by Adapt Planning by email dated 14/09/2023:

“Issue – Vegetation in the road reserve The application material requires the removal
of existing mature trees considered to be vegetation. PO5 of the Coastal Communities
Local Plan Code requires that development character retains and enhances key
landscape elements including existing character trees and areas of significant
vegetation contributing to the setting and character of the local plan area.

Information Required

1. Provide revised plans that allow for the preservation of trees 8 and 14 identified in
the Arboricultural Impact Assessment. The plans need to demonstrate no intrusion of
the tree protection zone of Trees 8 and 14.”



R ESPONSE
Tree 8
It was advised that the location of Tree #8 conflicts with the required driveway location to
facilitate safe entry and exist.

This point is to be clarified by the engineering company Westerapartners.

Tree 14
With Tree 14 located within 1m of the property boundary, it has grown up with the existing
dwelling within its theoretically calculated Tree Protection/Root Zone radius. That being said,
any form of construction located on the property boundary will have some degree of intrusion
into the tree’s active root zone. The Australian standard, AS4970-2009 Protection of trees on
development sites, tolerates a degree of root zone intrusion if the measurements of the project
design and the construction methodology have been taken into consideration and a suitably
qualified arborist has been engaged to assess the percentage of the root zone intrusion. The
key elements for attention when assessing root zone intrusion include the type of tree, its
vigour and ability to adapt to a change in surroundings and the soil type.

It was acknowledged in the submitted AIA report, ‘23_02_22_AIA_Adapt_2 Arakoon_2’, that
the proposed wall design and construction methodology would need to be taken into
consideration to reduce the likely impact on the tree’s roots. The design available at the time
did not show this level of detail.
