K - Preliminary Arborist Report (29.08.2019)

06.2 BULK EARTH WORKS WITHIN THE DEFINED TPZ
The Supervising Project Arborist will steer the site works and outline the action mitigation
measures as required.


In other defined areas of sensitivity for this project where excavation is required within a
defined TPZ, the Supervising Project Arborist will likely request a combination of a small
mud bucket and/or ripper arrangement on an excavator or similar machinery configuration
to help conduct comprehensive root investigation measures along the edge closest to the
subject tree(s) TPZ to help locate the presence of tree roots in an attempt to prevent
unforeseen tree root severance.


Tree roots which are deemed to be removed will be removed by the Supervising Project
Arborist or in combination with the machinery operator on a need by basis. Tree roots
which are defined for retention will be clearly marked with marker paint by the Supervising
Project Arborist to help guide/define the machinery operator work practices.


In determining tree root retention, the type of tree, tree canopy formation, tree structure,
tree health, soil structure/profile, number of tree roots etc., will be considered on a tree
root by tree root process with consideration of the constraints placed on the installation
methodology and tree preservation prerequisite.




06.3 LANDSCAPING DESIGN
All excavation with the TPZ for landscaping purposes i.e. planting shall be undertaken by
hand.     Any trees roots discovered (25mm>) are to be left and shall not be cut or otherwise
damaged. Where possible, the soil structure within the TPZ shall be preserved.
No large trees are to be planted within the TPZ.


It should be noted that detailed design summaries and construction considerations will be
personalised on the commission of an Arboricultural Impact Assessment (AIA).




07            ARBORICULTURAL WORK METHOD STATEMENT (preliminary)


The following Arboricultural Work Method Statement (AWMS) outlines the tree
protection measures for the general excavation construction works within defined TPZ’s.

This working document also informs the appropriate people undertaking the related work
tasks of their responsibilities as outlined in the following AWMS for works within a
defined TPZ:
