Tree and Vegetation Delivery Work Plan

Mitigation Measures
Replacement planting is proposed to mitigate the loss of the 30 trees to be removed from within the main works area. In addition to replacement planting, works within the root zones of trees N1, T15T19 and in the vicinity of T24 are proposed. Mitigation measures (as outlined in Section 4.2 below) will be implemented in order to protect trees N1, T15 – T19 and T24 which are to be retained.
Trees Requiring Removal Trees G1, G2 and T1 – T19 will be removed during the main works. Replacement planting for G1, G2 and T1-T19 will be undertaken as part of the public realm reinstatement on completion of construction of the main works. Replacement planting will be addressed in a future Outline Plan for the reinstatement works, which will include an Urban Design DWP (UD DWP) The method for removal of these trees will be informed by a qualified arborist in accordance with site observations, such as the proximity of surrounding buildings, tree size and overall condition. The methodologies used will include the following where relevant: • • •
Staged removal whereby the outer limbs are removed first, followed by inner limbs and the main trunk. Depending on the location of utility lines, tree stumps shall either be dug out or ground in situ. Removed tree debris will either be mulched onsite or removed for mulching off-site, depending on which is more practicable.
All trees permanently removed as part of the works will need to be replaced to address adverse effects on private properties, amenity and local streetscape. •

Replacement planting will be required for all trees that are required to be removed, as identified in Table 3-1 and Error! Reference source not found.. The location of replacement trees will be included in a replanting plan, which will be prepared as part of the UD DWP for the reinstatement of the CRL Mt Eden works. The UD DWP and accompanying replanting plan will consider the following in accordance with designation condition 55.3(c): o Replanting of removed trees at a ratio of at least 1:1; o Design for re-instatement of the area, including opportunities to replace removed trees with appropriate native species; o Input from the Auckland Council Parks Department (now Auckland Council Community Facilities) with regard to tree species / vegetation selection, tree pit construction and positioning of replacement trees; o An outline of the maintenance periods and responsibilities for care of the trees (i.e. maintenance is to be undertaken by the Requiring Authority for a period of five years for specimen trees and 3 years for all other landscape planting); and o Any consultation undertaken in relation to the replacement planting (refer to Section 5 of this TV DWP).
