1. Introduction 1.1.

The City Rail Link (CRL) project comprises the construction, operation and maintenance of a 3.4 km underground passenger railway, running between Britomart Station and the North Auckland Rail Line (NAL) in the vicinity of Mt Eden Station.

1.2.

Package 2 of the project extends from Wyndham Street and the proposed Aotea Station to the Mt Eden Station/NAL. The Nikau Street stormwater main will be affected by the proposed construction of the Newton Grade Separation Structure and will need to be diverted between Water Street and Nikau Street (the Project).

1.3.

The Project works involve the construction of a replacement stormwater main from the eastern end of Water Street, where it then passes beneath the CRL East Facing Connection (EFC) east of Mount Eden Road, and then continues west to connect into the existing main at the corner of Nikau Street and Ruru Street. The Project includes the construction of a central shaft at Mt Eden Road and retrieval shafts at Water Street and Nikau Street (see Figure 1 below).

1.4.

Construction support areas around the proposed shafts will need to be cleared and levelled. The buildings at 26, 28 Mt Eden Road and 16 Ruru Street will be demolished to enable the works. The Project also involves some works outside the designation, specifically the Water Street shaft and construction support area and a small part of the Mt Eden Shaft.

1.5.

The detailed location of the shafts and proposed works are attached as Appendix 1 of this report.

2. Report Author 2.1.

Amenity Tree Consultants Ltd (ATC) has been commissioned by Aurecon to assess the effects of the Nikau Street Stormwater Main Realignment (and enabling works package) on trees

2.2.

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 18-years. I am a fellow of the UK Arboricultural Association and a member of the New Zealand Arboricultural Association.

3. Scope and Purpose of the Report 3.1.

ATC has been engaged to provide the Trees and Vegetation Delivery Work Plan (DWP) for the vegetation impacted by the Nikau Street Stormwater Main Realignment proposal. The requirements for the Trees and Vegetation DWP are set out in condition 55 of the CRL Designation (Table 1).

Condition

Trees and Vegetation DWP Trees and Vegetation DWP shall be prepared to manage the adverse effects from the removal of trees and vegetation during the construction of the City Rail Link or any part of it.

The objective of the Trees and Vegetation DWP is to avoid the removal of scheduled trees as far as practicable. Where trees are identified for removal in surface works the Requiring Authority will remedy or mitigate the adverse effects of construction on trees and vegetation.

To achieve the above objective the following shall be included in the Trees and Vegetation DWP and implemented as required: Confirmation of the trees to be removed due to surface construction works and whether it is appropriate and feasible to relocate or store these trees for replanting. The removal of schedule trees which form a significant group should only be undertaken as a last resort; A list of trees, which due to being located in proximity to construction works, have root systems and / or foliage within and / or overhanging the surface designation footprint, and the methods to be used, where practicable, to protect these trees from construction works; Cross references to the Urban Design DWP and the proposed mitigation of any tree / vegetation removal through replanting trees at a 1:1 ratio, re-instatement of the area, and other methods.. In preparing the Trees and Vegetation DWP, the Requiring Authority shall seek input from the Auckland Council Parks Department with regard to tree species / vegetation selection, tree pit construction where deemed necessary, and the positioning of replacement trees and from directly affected land owners with regards to preferences for any replacement planting for vegetation / trees removed from private property or for any replacement planting on private property; Other methods to be used to monitor and report on the management of the adverse effects from tree / vegetation removal; and Cross references to the specific sections in the Communication and Consultation Plan which detail how the Auckland Council Parks Department, mana whenua (see condition 8) are consulted, and communication with the general public on the management of the adverse effects relating to the removal of trees and vegetation.

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 site assessments were carried out on 30th August and 15th September 2016

5. Vegetation Alteration 5.1.

Mt Eden Entry Shaft

5.2.

This shaft is the largest measuring approximately approximately 12.5m long, 9m wide and 14.6m deep, and will require the removal of all vegetation within and adjacent to its footprint.

5.3.

The construction of the shaft will also necessitate the demolition of 26 and 28 Mt Eden Road and the removal of the existing driveway to 28 Mt Eden Road.

Alternative access will be provided. This will result in the removal of vegetation at the front and rear of the 26 Mt Eden Road and vegetation adjacent to the fence at the front of 28 Mt Eden Road. The location of the vegetation requiring removal is shown in figure 2 below.

Details of the vegetation are provided in

table 2.

Nikau Street Shaft

5.15.

The Nikau Street shaft does not require any vegetation alteration

Water Street Shaft

5.17.

The Water Street Shaft and construction support area is outside the designation. For completeness this works area has been included in this Trees

and Vegetation DWP to ensure any effects on vegetation are appropriately managed.

5.18.

Whilst the shaft itself does not require any vegetation alteration, the footprint of the work area around the shaft shows a small area being removed.

The

vegetation requiring removal is all limited to self-seeded weed species including Pampus, Wattle and Privet. There is a large prominent Oak tree located outside the work area, growing adjacent to Boston Road. It is considered that it will not be affected by these current proposals, and that it will to a certain degree protected by the existing building below the bank on which it grows and existing use of the site as a car park. It should be noted that any change in the location of the work area this aspect will need to be reviewed.

6. Relocation and Transplanting

6.1.

Consideration has been given to the possibility of relocating/transplanting the trees requiring removal around the Mt Eden shaft. When assessing the possibility of transplanting mature trees several factors have to be considered to determine if it is viable, these include :-

6.2.



the existing health and structure of the tree,



time of year transplanting proposed



soil type and profile and the ability to obtain a viable root ball



access to the tree



being able to transport the tree to the final planting site



location of underground services



planting trees in new location, aftercare and maintenance



cost implications

In this instance given the size of the trees, condition and location transplanting is not considered to be a viable option. It is considered that replacement planting as part of the overall landscape proposal for the project will provide a better long term sustainable option.

CRL Stormwater Diversion

Page13

Amenity Tree Consultants Ltd

7. Replacement Planting 7.1.

It is considered that the Tree T1 and the trees in Group G2 are currently visually important and help soften the hard landscape and replacement should be sought. However, there is no scope for replacing lost vegetation as part of these advanced works. All vegetation lost will be included in future DWP for the main CRL construction works.

7.2.

The details for all vegetation removed as a result of the proposed works will recorded. As required by Designation Condition 55(c), all trees and vegetation that is removed will be replaced at a 1:1 ratio. The trees and vegetation removed as a part of these works will be replaced as a part of the landscaping in the final construction stages of the CRL project. At this time a Trees and Vegetation DWP an Urban Design DWP will be developed to facilitate the replacement of the vegetation lost during the stormwater realignment works associated with this project. The Auckland Council Parks Department, mana whenua and the general public will be consulted throughout the development of this DWP.

8. Consultation 8.1.

A Communication and Consultation Plan has been prepared for the Project works (TBC). Section 6 of this plan outlines the procedure undertaken in order to ensure that Construction Contractor undertakes consultation with the Auckland Council Parks Department and Mana Whenua. It also details the general communication that will be undertaken with the general public on the management of the adverse effects relating to the removal of trees within the Project area. Where agreed, the feedback from this consultation process will be incorporated into the Project Urban Design Delivery Work Plan.

9. Conclusion 9.1.

The site and project has some considerable unmovable restraints that are not possible to locate elsewhere such as the diversion of the stormwater, location of shafts, location of the actual rail corridor and the construction support area.

Replacement planting/landscaping will be required to mitigate the loss of this vegetation, however, there is no scope for replacing lost vegetation as part of these advanced works. The trees and vegetation removed as a part of these works will be replaced as a part of the landscaping in the final construction

stages of the CRL project. At this time a Trees and Vegetation DWP an Urban Design DWP will be developed to facilitate the replacement of the vegetation lost.

Appendix 3 Definitions

Dimensions: All dimensions are estimated unless otherwise indicated. Measurements taken with a tape or clinometer are indicated with a ‘*’.

Less reliable estimated dimensions 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 recorded in meters. If appropriate, it has been measured with a diameter tape. Trees that have multiple 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 life expectancy).

Vigour: This is an indication of the health of the tree. Trees have either been assessed as N = normal vigour or L = low vigour.

Comments: This column records any relevant features that may help clarify the retention category allocation.
