1. Introduction
1.1. Amenity Tree Consultants Ltd (ATC) was commissioned by Auckland Council
16th December 2011 to survey trees between 64-82 Trig Road (Northside Drive
East) and then to provide an arboricultural report to accompany a Resource
Consent application to remove generally protected vegetation, as determined
by Auckland Council Waitakere Region District Plan (Operative) 2003.
2. Report Author
2.1. This report has been written by Stephen Bishop. I am the Director of ATC and
hold the following relevant qualification: Higher National Diploma in
Arboriculture. I have been a qualified and practicing arborist in local
government (United Kingdom and New Zealand) and private consultancy for
13-years. Furthermore, I am a fellow of the UK Arboricultural Association, a
member of the New Zealand Arboricultural Association and the International
Society of Arboriculture.
3. Scope and Purpose of the Report
3.1. ATC has been engaged to provide a report that addresses and identifies thefollowing:
Actual and potential effects of the proposed work to protected vegetation,
as determined by Waitakere City District Plan (Operative) 2003.
4. Report Details and Limitations
4.1. Unless otherwise stated:
All vegetation has been inspected from ground level only.
All vegetation measurements (heights, stem, girths, and canopy spreads)
are approximate.
No samples of vegetation or soil have been taken for analysis.
Amended or supplementary plans are not to scale.
The professional opinion expressed on the health status or structural
integrity of trees or other vegetation is valid at the time of inspection and
cannot be guaranteed beyond the date of the report, given the variability of
natural organisms and the influences of climatic events. It is always advisable
to reassess vegetation in high risk areas following storm events.
This report has been prepared for the particular project described to ATC
Ltd. No responsibility is accepted by ATC or its director for the accuracy of any
information provided by third parties and the use of this report or any part of it
for any purposes beyond the agreed scope.

4.2. The initial site assessment and report was carried out on 1st July 2010. Re
assessment of the trees following finalised plans was carried out on 23rd
January 2012 and 15th November 2012. The weather conditions were calm,
sunny and clear.

7. Proposal Work
7.1. The location of the work area is shown in Figure 2. A more accurate site plan
showing the extent of works is provided with the consent application.
7.2. The detailed design and construction method for the new road layout and storm
water pond has been completed. And is not expected to change in any
significant detail. The following works to trees will be necessary to construct
the proposed road.
Removal
Fifty (50) individual trees
Twenty (20) Shelter belts or groups of trees
7.3. Please note that not all the trees surveyed/assessed and entered into the tree
removal schedule (appendix 2) are protected under the District Plan e.g.
Macrocarpa, Silver Dollar gum, Willow and some species of Poplar. However, in
this instance, it was decided to include all vegetation being removed to aid in
the overall assessment and extent of work.
7.4. The removal of the subject vegetation will have less than minor effects upon
the visual amenity of the area.
7.5. The location of the subject vegetation is detailed on the plan attached as
Appendix 1.
8. Waitakere City - Tree Protection Rules
8.1. Table 3 – Applicable Tree Protection Rules
General Natural Area Rules
Rule 2.1 – Permitted ActivitiesActivities meeting the following Performance Standards are Permitted Activities:(a) any vegetation alteration of:(i) native vegetation and exotic vegetation which is less than 6.0metres in height andless than 600mm in girth (as measured 1.4metres above the ground)(ii) vegetation listed in the Removable Vegetation Appendix and the EnvironmentallyDamaging Plants Appendix
Rule 2.2 Controlled Activity
(d) any vegetation alteration not meeting the standards in Rule 2.1 undertaken orrequired by a network utility operator necessary for the maintenance of that operator’sworks
Amenity Tree Consultants Ltd
Northside Drive East – ATC 148 Page 7
8.2. Statutory Assessment
8.3. Section 95a of the Resource Management Act allows a consent authority to
publically notify an application for resource consent. However, a consent
authority cannot notify an application if a rule or national environmental
standard precludes public notification.
8.4. Waitakere Council’s District states that,
“In relation to Controlled and Limited Discretionary Activities applications for
consent need not to be notified and the written approvals of affected persons
will not be required, nor in terms of limited notification under the Act, will notice
to adversely effected persons need to be served”.
8.5. It is considered that there are no special circumstances under Section 95(4) of
the Resource Management Act (1991) that would justify notification of the
vegetation alteration aspects of the application (see Assessment of Effects
Section 9).
9. Arboricultural Assessment of Effects
9.1. This section provides an Assessment of Effects (AEE) for the proposed
vegetation works in accordance with section 88 (2b) of RMA:
“(2) An application must:
a) be made in the prescribed form and manner and
b) include, in accordance with the Schedule 4, an assessment of effects in
such detail as corresponds with the scale and significance of the effects that
the activity may have on the environment”
9.2. Permanent Effect From the Proposed Tree Removal
Brief details of the trees requiring removal have been listed in section 7. A full
description/schedule is attached as appendix 2.
9.3. Amenity Values and Neighbourhood Character
9.4. The access track/road between 64 and 74 Trig Road does not currently provide
any public through access. Therefore the numbers of general public using the
track is limited to the property owners and their visitors. The subject trees are
clearly visible when on the access track but not readily viewed by members of
Amenity Tree Consultants Ltd
Northside Drive East – ATC 148 Page 8
the public. Therefore, it is considered that they do not provide a significant
visual amenity and any shot term effect will be minor in nature and confined to
a relatively small area. Replanting with native species along roadside bunds
will be taking place as part of the overall proposed works. This will in the
medium to long term greatly enhance the visual amenity and increase the
native flora in the area.
9.5. Potential for relocation
9.6. None of the trees assesed are suitable for relocation.
9.7. Alternative methods/Location
9.8. No significant trees or vegetation were observed that would warrant
extraordinary efforts to retain or relocate (if possible), or to seek alteration to
the proposed route of the SH16 link road.
9.9. The site is not known to be Historically, Culturally or Spiritually significant,
therefore there will be no adverse effects in this regard.
9.10. Effects on the Overall Resilience, Bio Diversity and Integrity of
the Green Network
9.11. Objective 2 of the District Plan acknowledges that the ecological integrity and
biodiversity of the Green Network is best served by maintaining the range of
native species and genetic stock within the City and that active enhancement,
such as weed and pest control and re-stocking with native plants may be
necessary. It is considered that the proposal will not cause any adverse effect
to the Green Network.
9.12. The majority of the trees/vegetation being removed is exotic species. Mass
replanting of the roadside bunds with native plants will increase the biodiversity
and green network of the City.
9.13. Effects of Ground Stability
9.14. The removal of vegetation has the potential to create, contribute or exacerbate
ground stability problems. In this instance the extent of works being carried out
to SH16 will mean that this is not an issue in this instance.
Amenity Tree Consultants Ltd
Northside Drive East – ATC 148 Page 9
9.15. Effects of Noise and Disruption Generated by Arboricultural
Works
9.16. Power tools and machinery necessary to carry out arboricultural works such as
removal, chipping and stump grinding, generate high noise levels, usually on an
intermittent rather than continuous basis; that is likely to extend beyond the
working area. Some arboricultural operation will generate dust and wood chips
that may be carried by the wind into land adjacent to the working area.
9.17. Vehicles and machinery used in arboricultural works can be of medium goods
vehicle size (up to 12 tonnes). However, in this instance there is adequate on
site parking and maneuvering and as such the effects are considered to be no
more than minor and will be adequately mitigated by the proposals detailed in
Section 9.22.
9.18. Effects on Remaining or Surrounding Vegetation
9.19. The removal of vegetation can affect the health and vigour of surrounding
vegetation through edge effects. In this instance none of the subject trees
provide significant shelter to any other surrounding protected vegetation.
Linkages between habitats and other natural features will also remain
unaffected due to the small percentage of vegetation being removed from the
overall area and the extent of remaining vegetation within the immediate
vicinity. In view of these factors, the effects of the trees being removed are
considered to be no more than minor.
9.20. Overall Summary of the Assessed Effects
9.21. It is considered that the identified permanent and temporary environmental
effects of the required vegetation alteration, to facilitate the proposed works to
SH16, will be no more than minor and any effects will be adequately mitigated
by the proposals detailed in section 9.29. In addition, no persons are
considered to be adversely affected by the proposal.
9.22. Mitigation, Restoration and Enhancement
9.23. The removal of vegetation will be carried out by suitably qualified and
experienced persons. Care will be taken to ensure that adjacent protective
vegetation is not effected.
Amenity Tree Consultants Ltd
Northside Drive East – ATC 148 Page 10
9.24. Noise management will be in accordance with the principles set out in
NZS6803P: 1984 “The measurement and Assessment of Noise from
Construction, Maintenance and Demolition Work”. Working hours for
arboricultural works will be restricted to the following:
Monday to Friday: 7.30am to 7.00pm
Saturday: 7.30am to 5.30pm
Sundays and Public Holidays: No work
All works will be carried out using machinery associated with modern
arboricultural practice.
All vehicles and machinery not able to be located within the working area
will be positioned to minimise disturbance to local traffic flow and available
parking spaces.
As far as is practicable dust and wood chips associated with the works will
be contained, cleared and disposed of at appropriate land fill or other
storage facilities.
9.25. No machinery or vehicles will be stored, parked or operated within any area
outside the proposed building footprint
9.26. It is anticipated that mass native planting continue to be carried out on
roadside bunds at various places along SH16. In effect all trees being removed
will be replaced at a minimum ration of 2-1. Details of all landscaping including
planting plans will be provided at a later date.
10. Conclusion
11.1 The proposed link road requires a “Controlled Activity Resource Consent” for
the removal of protected vegetation.
11.2 The assessment carried out in this report, in particular within Section 9, has
identified the actual and potential environmental effects of the proposed works
in accordance with Section 88 (2) of the RMA and concluded that no more than
minor effects to the environment or remaining vegetation will result.

Definitions
Dimensions: All dimensions are estimated unless otherwise indicated. Measurementstaken with a tape or clinometer are indicated with a ‘*’. Less reliable estimateddimensions are indicated with a '?'.
Species: I based the species identification on my visual observations and have placed '?'after the name of a tree where I have some doubt over its identity.
Height: Height is estimated to the nearest meter.
Trunk diameter: Trunk diameter is estimated at 1.4m above ground level and recordedin meters. If appropriate, it has been measured with a diameter tape. Trees that havemultiple stems are indicated with ‘M’.
Maturity: Tree maturity has been assessed as mature (last one third of life expectancy),maturing (one third to two thirds life expectancy) and young (less than one third lifeexpectancy).
Vigour: This is an indication of the health of the tree. Trees have either been assessedas N = normal vigour or L = low vigour.
Comments: This column records any relevant features that may help clarify the retentioncategory allocation.
