9 GENERAL TREE PROTECTION PR

All trees or groups of trees specified or shown to be retained are to be protected from damage
with temporary fencing as specified in AS 4970-2009 Protection of Trees on Development
Sites and in the Arborist’s report. Temporary fencing must be erected at the boundary of the
TPZ marked areas must be installed in accordance with AS4970 prior to works commencing.

All Works within a designated TPZ of retained vegetation must be supervised by the Project
Arborist (AQF Level 5). Take all necessary precautions, including but not limited to the
following:

e Appropriate signage i.e. ‘Tree Protection Zone’ and ‘No Go Zone’ must be erected at the
boundary of TPZ to prevent vehicles from entering and prevent stockpiling occurring near
retained trees / vegetation;

e No damage to be caused to tree trunks and bark (i.e. do not attach guides or stays to
trees / vegetation);

e Noexcavation works / open trenching to encroach within the TPZ of retained trees unless
under the direct supervision of Project Arborist;

e Where necessary to cut roots, this shall be undertaken by the Project Arborist;

e No storage or otherwise placing of spoil, bulk or potentially harmful materials (i.e.
construction refuse, concrete waste, herbicides, diesel, etc.) under or within 1 m of TPZs.
Prevent windblown materials such as cement from harming trees and plants;

e Avoid ground compaction under trees. If compaction occurs (i.e. from site access or the
location of a construction plant or vehicle parking) notify the Project Arborist and obtain
their instructions;

e Ground Protection: Where construction encroaches into the TPZ of trees to be retained it
shall be necessary to install protection to avoid compaction of the ground surface, lateral
and absorbing roots;

e Any damage to trees during works is to be rectified according to AS 4373/96 Pruning of
Amenity Trees and best horticultural practices. The Project Arborist must oversee works,
and

Where deemed beneficial mulch entire ground surface within TPZ with Forest Blend Organic
Mulch or site mulch to a depth of 100mm and install a temporary irrigation system or manually
water to ensure that soil moisture levels are adequately maintained.
