1.0 INTRODUCTION

1.1.1 This report has been prepared to provide an arboricultural impact assessment for trees within 1126-1146

Centre Road, Oakleigh South, the site of a proposed Kaufland Store. Trees within the site have previously been

assessed by Tree Logic Pty Ltd in Arboricultural Assessment and Report 1126-1146 Centre Road, Oakleigh

South, 6th September 2018.

1.1.2 The aim of this report is to provide an arboricultural impact assessment of the proposed development on

trees previously assessed by Tree Logic. The assessment has been undertaken by:

▪ Undertaking a site visit on 22nd February, 2019 and reviewing tree assessment details prepared by

Tree Logic;

▪ Reviewing the proposed site plan and assess potential impacts on site trees;

▪ Providing an overall assessment of the retention status of each tree or tree group within the site

against the guidelines of AS4970-2009 Protection of Trees on Development Sites.

1.1.3 The numbering for trees has been adopted from the previous report prepared by Tree Logic.

2.0 REVIEW OF PREVIOUS REPORT

2.1.1 An on-site review has been undertaken for all trees previously assessed within the site by Tree Logic. The

review reveals that the data previously recorded generally accords with the Arboricultural Descriptors in

Appendix 3 of the Tree Logic report, utilised as the basis for assessment. Calculated tree protection zones

accord with measurements undertaken by Landscape DEPT for each tree on site.

2.1.2 Tree 83 was identified as a Spotted Gum (Corymbia maculata) in the previous report but is a Smooth-barked

Apple (Angophora costata). This does not otherwise alter its status as a specimen of high arboricultural value.

3.0 PROPOSAL

3.1.1 Demolition of the existing retail warehouse and construction of a new supermarket and associated car park is

proposed in the northern portion of the site. Revised road functional layouts are proposed for access to

Centre Road and Clarinda Road.

3.1.2 The following drawings have been reviewed in the preparation of this assessment:

3.1.3 Trees located in areas indicated as “subject to further master planning and future approval” on the

architectural plan in the south east and southern portions of the site are assumed to be retained, unless

located close to proposed works subject to the current proposal.

3.1.4 The assessment has been undertaken within the guidelines of AS4970-2009 Protection of trees on

development sites against the architectural plan.

3.1.5 Of the 98 trees and 1 tree group assessed within the study area:

▪ 2 trees have been assessed of high arboricultural value;

▪ 64 trees and 1 tree group have been assessed of moderate arboricultural value;

▪ 32 trees have been assessed of low or no arboricultural value.

3.2 TREES REQUIRING REMOVAL

3.2.1 The following trees listed in Table 3-1 below will require removal to facilitate construction of the proposed

supermarket, located either within or too close to the building footprint, or within revised car parking areas

and road functional layouts.

3.2.2 Of the 34 trees requiring removal:

▪ 18 trees have been assessed of moderate arboricultural value;

▪ 16 trees have been assessed of low or no arboricultural value;

3.2.3 Of these, Tree 1, a Snow Gum is shown in a slightly different parking configuration on the landscape plan with

the parking space to the west of the tree indicated as garden bed, as shown at Figure 1, below. In this scenario

the tree can be retained and further investigation could be undertaken by a project arborist to determine the

potential impact of construction of the additional western car space on the viability of the tree.

3.2.4 Similarly, Tree 24, a Wych Elm, and Tree 25, a Snow Gum, are shown as retained on the landscape plan with a

modified car parking configuration along the eastern boundary, where car parks are only indicated subject to

investigation by an arborist (Figure 2). As for Tree 1, with the car parks removed as shown on the landscape

plan, both Tree 24 and 25 could be retained, and car parks only permissible adjacent to the trees subject to

further investigation. It is noted that Tree 24 is a low value specimen with a limited life expectancy of 6-10

years and removal and replacement with a new tree might be considered a superior long-term outcome.

3.2.5 Tree 3, a Manna Gum is also indicated as retained on the landscape plan, as shown on Figure 1. This tree is

currently located in a broad landscape area that extends to its south and west. With construction of a new

access road to the south of the tree through this landscape area, the tree is unlikely to remain viable, even


FEBRUARY 2019 - 3

with the deletion of adjacent proposed car parks. Unless a non-destructive root investigation demonstrates

the tree can be retained as a viable specimen, the status of this tree remains as removed.

3.3 TREES THAT CAN BE RETAINED

3.3.1 The following trees listed in Table 3-2 below can be retained within the context of the proposed development.

In the main these are trees well separated from proposed works with no encroachment whatsoever into tree

protection zones (TPZs), or with minor encroachments of no more than 10% of the total TPZ.

3.3.2 Included amongst this category are several trees in the existing car park where revised car parking is confined

to existing areas of pavement or is proposed further away from trees. Similarly, the alignment of the existing

service road into the west of the site is assumed to be retained. Provided re-surfacing of car parking areas and

the western service road does not alter levels within the TPZs of trees proposed to be retained, these trees

should not be adversely impacted by the proposed scheme.

3.3.3 Trees indicated with an asterisk (*) have noted encroachments slightly higher than 10%, but with standard

protective measures implemented as part of a tree protection plan conforming to AS4970-2009, are

anticipated to remain viable specimens that can be incorporated successfully into site development.

3.3.4 Of the 64 trees and 1 group that can be retained:

▪ 2 trees have been assessed of high arboricultural value;

▪ 45 trees and 1 tree group have been assessed of moderate arboricultural value;

▪ 17 trees have been assessed of low arboricultural value;

3.3.5 Whilst Trees 46, 48 and 49, all River She-oaks, can be retained, these are shown as removed and replaced with

Yellow Gums on the landscape plan. In view of their limited ratings as either moderate C or low arboricultural


FEBRUARY 2019 - 6

value trees, replacement with new specimens to achieve a more cohesive landscape scheme is an acceptable

outcome.
