1. Introduction

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. The CRL also involves the construction of two new underground stations at Aotea and Karangahape and a redeveloped Mt Eden Station (refer to Figure 1-1). The design and construction of the CRL infrastructure between Aotea and Mt Eden Stations is being delivered by the Link Alliance.

This Trees and Vegetation Delivery Work Plan (TV DWP) has been prepared in relation to early works along and in the vicinity of Normanby Road, hereafter referred as the ‘Normanby Road early works’.

1.1 Overview of CRL works in Mt Eden

The CRL works in the Mt Eden area involve the construction of the southern section of the tunnel structures and the tie-in to the existing NAL, including the construction of the redeveloped Mt Eden Station. The Mt Eden Active Construction Zone (ACZ) and Construction Support Areas (CSA) for the NAL Mt Eden section are generally located between State Highway 1 (SH1) to the east and Dominion Road to the west.

The works in this area include:

Construction of an underground grade separation structure near Mt Eden Station; A new Mt Eden Station building incorporating passenger linkages; Modifications to the existing Mt Eden Station platforms; Road over rail bridges at Mt Eden Road, Normanby Road and Ruru Street with sections of road realignment; Grade separation structures and the east- and west-facing connections for the existing and new rail lines to pass-over and connect with each other;

Pedestrian and cyclist bridge structures at Fenton Street and Porters Avenue; and New road linkages within the reinstated area post-construction.

Given the nature and scale of CRL works in Mt Eden, construction will be undertaken in a staged manner.

This TV DWP only relates to one component of the CRL Mt Eden works, the Normanby Road early works, as described in Section 2 below.

1.2 Purpose of the Trees and Vegetation DWP

In accordance with CRL Designation Condition 55, this TV DWP has been prepared to identify measures that will be implemented to mitigate and manage potential adverse effects on trees and vegetation during the Normanby Road early works.

The objective of this TV DWP (designation Condition 55.2) is:

To avoid the removal of scheduled trees as far as practicable; and Where trees are identified for removal during surface works the Requiring Authority will remedy or mitigate the adverse effects of construction on trees and vegetation.

This TV DWP has been developed in consultation with the CRL Mt Eden Community and Business Liaison Group (CLG) and has undergone Independent Peer Review (IPR) prior to submission to Auckland Council (as per designation conditions 7 and 11). A record of the consultation and review outcomes, including the Link Alliance’s response to matters raised, is included in Appendix A.

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. Section 4.2

To achieve the above objective the following shall be included in the Trees and Vegetation DWP and implemented as required:

(a) 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 scheduled trees which form a significant group should only be undertaken as a last resort; Section 3

(b) A list of trees, which due to being in proximity to construction works, have root systems and / or foliage within and / or Sections 3.1 and 4.2

overhanging the surface designation footprint, and the methods to be used, where practicable, to protect these trees from construction works;

(c) 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;

(d) Other methods to be used to monitor and report on the management of the adverse effects from tree / vegetation removal;

(e) 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.

1.4 DWP Review and Updates

This TV DWP is a live document that will be reviewed and updated as a result of a material change to the Normandy Road early works, or to address unforeseen adverse effects on trees and vegetation arising from construction, or unresolved complaints. Refer to the Construction Environmental Management Plan (CEMP) for further detail on the review and updating process.
