1 B RIEF
This assessment was commissioned by Mr Robert Wadland; Consult Arborist Pty Ltd has
been requested to conduct an Arboricultural Impact Assessment on the subject trees located
adjacent to Lot 17 at 30 Hastings Street, Noosa Heads to the rear of the Lot in relation to the
proposed project design and to provide information relating to their suitability for retention in
the proposed project design.

A desktop review of supplied documents has been undertaken to understand the project
design and required works proposed.

Version 2 was requested to reflect only retained trees / palms on site following recent tree
removals.

Version 3 was requested to reflect the updated set of plans.

2 S ITE I NSPECTION

3 S COPE AND L IMITATIONS
The purpose of this report is to provide advice and guidance on the subject trees located within
the rear of Lot 17/30 Hastings St., Noosa Heads in relation to the proposed project design.

Consult Arborist has reviewed the supplied documentation relating to the site, the existing
trees/vegetation, and the site layout with consideration to the design, future use and
buildability of the Project. This report aims to provide guidance and direction with the practical
consideration of the suitability for retention of individual trees and is guided by the Australian
Standard, AS4970-2009 Protection of trees on development sites, industry best practice and
professional experience.

The subject trees are detailed in the report have received an International Society of
Arboriculture (ISA) Basic Level 2 assessment with consideration to the design and future use
of the Project.

The tree data has been allocated to the subject trees by Consult Arborist within the report to
assist with calculations and identification.

See attached photographs, plan extracts and maps for identification purposes.

This report does not take into consideration changes to the site design or activities of which
Consult Arborist has not been requested to comment on or been advised of.

This report does not take into consideration extreme weather events or future pest and disease
outbreak which may affect the tree’s health, condition and retainability.

All assessments of the retained tree/s have been made visually from the ground and include
the use of basic tools and techniques, i.e. cavity probing, minor root collar excavation,
measuring tapes and devices and photography to gather information. No additional specialist
equipment was used and no conclusive comments on what may have or may be happening
within the internal structure of the tree will be made. No tissue or soil samples have been
collected or submitted for testing.

The information contained in this report is based on a visual inspection of the tree/s and their
location/s, species, health and condition at the time of the inspection from a ground level. The
additional information provided is the author's opinion and is a 'snapshot in time' of the specific
tree's health and condition at the time of the quoted inspection and no guarantee can be given
that faults or issues may not arise in the future.

4 S ITE L OCATION AND D ETAILS
The site of Lot 17 – 30 Hastings Street is in the Noosa Council suburb of Noosa Heads, within
the popular Hastings Street precinct. The site consists of a tourist townhouse accommodation
development constructed approximately 20 years ago. As part of the original development
many trees and palms were planted between each of the units providing a natural feel and
privacy to the closely positioned dwellings.




        Figure 2: Google map overview of the existing site with subject trees circled


The current proposed plan consists of a major renovation of the existing Lot 17 dwelling
including an additional extension to the rear that conflicts with a number of landscape trees
and palms.

No other vegetation on the site is included in this report.

This assessment is based on the current design and site layout, as referred to in Documents
Reviewed, without alteration to the project layout.

Comment and guidance will be provided on each subject tree and its retention within the
currently proposed project design, and where required, justifications and observations will be
offered relating to the degree of intrusion into the calculated Tree Protection Zones (TPZ) as
per AS4970-2009 Protection of trees on development sites.

  The subject trees as tabled above, are all found in the rear area of Lot 17. Trees #1 and #2
  are the dominant trees. The remaining trees and palms are suppressed with stunted growth
  and forms due to competition from the larger trees and their proximity to the existing structures.

  The design of the renovation directly conflicts with the location of Tree #2, the Hills Fig. The
  project design does not allow for this subject tree to be retained.

  Palm #1 is an undesirable species but does help to retain some maturing landscape to the
  rear of Lot 17. There are a few small suppressed Lilly Pillies located at the base of this palm
  that could be pruned during the construction phase and allowed to regrow on completion.

  Palms and trees within the boundary of adjacent Lots are proposed to be retained, see Picture
  3: Retained palms Picture 3.

  All proposed retained trees and palms within and adjacent Lot 17 and directly adjacent are to
  be protected in accordance with AS4970-2009 Protection of trees on development sites,
  during the construction phase of the project.

  5.2     SUMMARY TABLE
  Table 2 below provides a brief summary of the subject trees/palms found within the site
  boundary of Lot 17/30 Hastings Street. #1 Cocus Palm and a few understory juvenile Lilly
  Pillies are proposed to be retained and protected during the life of the project.

6 T REE P ROTECTION
Due to the nature of the site standard Tree Protection Fencing will not be achievable or
practical throughout the site. The typical steel mesh panels are not suitable everywhere to
create the Exclusion Zones. The alternative proposed is orange mesh erected around the
retained vegetation and boundary to adjacent Lot to restrict access. With Council's approval,
the TPZ fence may consist of 1m high plastic orange mesh barrier fencing with star pickets
with end caps as support, spaced at 4 – 5m and attached with zip ties as an alternative to
steel mesh panels.

When the access and construction requirements have been established, the exclusion zones
can be positioned for the trees to be retained and the alignment of the TPF can be determined.
The TPF is required to be installed in the presence and under the guidance of Consult Arborist
prior to any construction works commencing on the site and should remain intact until the
completion of all works.

Where required ground protection is to be installed specific to requirements and can include
scaffold walkways, temporary decks, metal/ply sheets, geo fabric and additional forest mulch
to an increased depth of 200-300mm to spread the load of site activities and minimise ground
disturbance.

Trunk protection, to prevent direct contact with the tree’s trunk and buttress roots can be
installed. This can comprise of Geo fab/20mm thick hessian and wooden battens
strapped/taped to the tree’s trunk with a skirt over the buttress roots.

These protection measures will be established between the contractor and the Project
Arborist.

This information contained in this report has been prepared on an independent basis, free of any bias and represents the honest
opinion of the consulting arborist.

All data is based on visual inspection of the tree/s and its/their location at the time of writing, unless otherwise stated, and contains
opinions, advice and recommendations based on information and data gathered from site inspections carried out by the author
and information supplied by the Client (Wadland).

All information received from the Client shall be deemed to be true, accurate and up to date.

To the extent permitted by law, you agree Consult Arborist Pty Ltd is not liable to you or any person or entity for any loss of or
damage caused or alleged to have been caused (including loss or damage resulting from negligence) either directly or indirectly,
by your use of the information made available in this report. In no event will the author be liable to you for any lost revenue or
profits, or for special, indirect, consequential or incidental damage (however caused and regardless of the theory of liability)
arising out of or related to your use of that information, even if the author has been advised of the possibility of such a loss or
damage.

Consult Arborist cannot be held responsible for the effects of non-conformance works performed, by unsuitably qualified staff or
without the supervision of Consult Arborist.

Unless otherwise stated this report cannot be used within a court of law or any legal situation without the prior consent of Consult
Arborist Pty Ltd. The author shall not be required to give testimony or to attend court by reason of this report unless subsequent
contractual arrangements have been made.

The information contained in this report refers only to the tree/s that were inspected on 26/09/2019 & 23/04/2020 and reflects the
condition of the tree/s at the time of the inspection.

There is no warranty or guarantee, expressed or implied, that the problems or deficiencies of the plants or property in question
may not arise in the future. Likewise, remedial treatments cannot be guaranteed.

Arboriculturalists cannot detect every condition that could possibly lead to the structural failure of a tree. Trees are living
organisms that fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Consult
Arborist Pty Ltd and the author cannot guarantee that a tree will be healthy or safe under all circumstances, or for a specified
period of time.

This report does not take into consideration the possibility of extreme weather or other events over which Consult Arborist P ty
Ltd has no control.

Treatment, pruning and removal of trees may involve considerations beyond the scope of the Arboriculturalists services, such as
property boundaries and ownership, disputes between neighbours, sight lines, landlord-tenant matters and related. Consult
Arborist Pty Ltd cannot take such issues into account unless the complete and accurate information is given to them. Likewise,
Consult Arborist Pty Ltd cannot accept any responsibility for the authorization or non-authorization of any recommended treatment
or remedial measure.

Arboriculturalists are tree specialists who use their education, knowledge, training and experience to examine trees, recomme nd
measures to enhance the beauty and health of trees and attempt to reduce the risk of living near trees. Trees can be managed,
but they cannot be controlled. To live or work near a tree involves some degree of risk. The only way to eliminate all risks
associated with a tree is to eliminate the tree.

Clients may choose to accept or disregard the recommendations of Consult Arborist Pty Ltd or to seek additional advice.

A PPENDIX 1 - D EFINITION OF T ERMS
The following criteria have been used in the VTA and arboricultural appraisal to gather information and determine the required
management options on the grounds of public health and safety. Measurements are approximate, made visually by eye unless
otherwise stated.

 Age Class:
 Young:            Early stage of growth, immature size
 Early Mature:     Fast-growing well-established tree which has not yet reached mature size
 Mature:           The tree reached its mature size, exhibits slowing growth rates with early stages of naturally forming dead
                   or dysfunctional wood.
 Over Mature:      The tree has reached mature size and is unlike to increase significantly in height or mass. Retrenchment of
                   the upper crown with increased vegetative vitality in lower crown, increased fungal activity and wood decay,
                   increase colonisation by flora and fauna.
 Veteran:          Tree with advanced retrenchment, reduced crown size and annual increment growth, extensive hollowing,
                   crown collapse, low vigour, advance heartwood decay, advanced colonisation by fauna and flora.
 Health:
 Good:             Tree with no defects or disorders which are notable. Full canopy with good colour foliage. Minimal pathogen
                   damage.
 Fair:             Tree with minor defects or disorders which are notable. Some deadwood within what can be an unbalanced
                   canopy, foliage generally with good colour although some discolouration may be present typical of species
                   in location. Minor pathogen damage.
 Poor:             Tree with major defects or disorders which are notable. The tree has considerable deadwood present,
                   discoloured or distorted leaves indicating a further decline of the tree. Detrimental pathogen damage.
 Dead:             Dead or dysfunctional moribund tree.
 Structure:
 Good:            Tree with good unions and no branch defects. Sound trunk with no / minor defects. Good buttress and root
                  structure.
 Fair:            Tree with minor defects or disorders which are notable. Small areas of bark missing. Small cavities or minor
                  unfavourable branch unions may be present. Minor damage to roots.
 Poor:            Tree with major defects, large hollows, weak unions and/or problematic damaged roots.
 Hazardous:       This implies a tree with a major defect that may fail at any time
 Protection of Trees:
 DBH:             Diameter at Breast Height - The approximate diameter of the trunk is measured visually in millimetres at a
                  height of 1.4m.
 TPZ:             As specified in the AS 4970-2009 Protection of trees on development sites, the Tree Protection Zone (TPZ)
                  is the principal means of protecting trees on the development site. The TPZ is a combination of the root and
                  crown area requiring protection. This area should be isolated from construction disturbance so that the tree
                  can remain in a viable condition. The TPZ incorporates the Structural Root Zone (SRZ).
                  The radius of the TPZ is calculated for each tree by multiplying its trunk diameter at 1.4m above ground by
                  12, e.g. 300mm [email protected] x 12 = 3.6m Tree Protection Zone (TPZ)
                  A TPZ should not be less than 2m or greater than 15m (unless crown protection is required).
 SRZ:             Structural Root Zone (SRZ), as specified in AS 4970-2009 Protection of trees on development sites, is the
                  surface area of protection required to maintain a tree’s stability – a larger area is required to maintain a tree
                  in viable health. It is only necessary to calculate the SRZ when major encroachment into a TPZ is proposed.
                  The SRZ for trees with a trunk diameter less than 150mm will be 1.5m.
