1. INTRODUCTION
Arboriculture Contractors Australia was contacted by Altum Constructions and
requested that an AQF Level 5 Arborist attend 245 David Low Way Peregian beach
QLD to assess trees located on verge and with proposed widening of footpath of 2
meters how this will impact retention of trees, trees were inspected, measured, and
photographed in accordance with industry best practice standards.
2. KEY OBJECTIVES
• In the event that the existing vegetation in the front road reserve is retained and the
existing footpath is widened 2m wide as per Condition 33
• Inspect existing vegetation for retention, offer recommendations.

4. Methodology
The area was physically surveyed and assessed using non-invasive Arboricultural techniques.
Assessment of the trees was conducted using Visual Tree Assessment (VTA) from Mattheck
& Breloer (1994 & 1999), with additional references from Matheny & Clark (2004), Londsdale
(1999) and Harris (1999 & 2004). Additional references to tree anatomy and structure are
taken from Shigo (1986 & 1991), including references to roots from Perry (1982).
Specifications on protection of trees and tree roots during construction activities are taken
from AS4970-2009, including additional references from Urban (2008). Specifications for tree
pruning are taken from AS4373-2007, with additional references from Shigo (1986 & 1991).
Tools used to perform this Arboricultural assessment included:
• Digital photos were taken with an Apple iphone.
• A Zeppelin builders tape was used to measure distances from the borders of
infrastructure to the adjacent trees, and DRF to calculate RPZ.
• A Thor X710 sounding hammer was used to detect for decay.

DBH (Diameter at Breast Height) – The diameter of a trees trunk measured at 1.4m above ground level

DRF (Diameter at Root Flare) - The diameter of a tree measured just above the root flare at ground level

6. Discussion on Visual Tree Assessment
• All three established trees located on verge show good health and vigour, tree
one is located close to proposed construction of 2m wide footpath exstention,
providing Arborist is on site during any works within 500mm of base the new
footpath construction will not affect health of tree.
• Trees two and three are located a significant distance from new construction of
2m wide footpath no not impact.
7. RESULTS
• All trees located along footpath are suitable for retention
8. RECOMMENDATIONS
• Light canopy lift prune on tree two to allow crews to complete works and reduce
potential of damage to low limbs
• Diploma arborist onsite during works being carried out around the base of tree
one.
