Trees and Vegetation Delivery Work Plan
Groups 2 & 3 Groups 2 & 3 are identified as a row and grouping of vegetation growing in a heavily modified industrial environment. Due to hard surface constraints and available locations post works, it is considered that this vegetation is unsuitable for transplant. Group 4 Group 4 consists of an area of wilding weed and lower value specimens, including Brush Wattle & Karamu. The trees are growing on a rocky outcrop which is proposed for clearance to enable full use of the hard stand area during construction, and to improve current passive surveillance for the safety of users of the temporary car park to be established during construction. It is not deemed practical nor necessary to transplant these trees.
4. Mitigation Measures Replacement planting is proposed to mitigate the loss of the 42 trees (excluding weed species) from within the Normanby Road early works area. In addition to replacement planting, mitigation measures for works within the root zones of tree N1 and in the vicinity of T24 are proposed. These mitigation measures (as outlined in Section 4.2 below) will be implemented in order to protect trees N1 and T24 which are to be retained.
4.1 Trees Requiring Removal Replacement planting will be undertaken as part of the public realm reinstatement on completion of construction for the CRL Mt Eden works, including works in the Normanby Road area. This will be addressed in a future Outline Plan, which will include an Urban Design Delivery Work Plan (UD DWP). Amongst other things, the UD DWP will include a replanting plan which will show the type and location of replacement trees. The method for removal of these trees will be informed by a qualified arboricultural practitioner 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 underground 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 (with the exception of weed species) permanently removed as part of the early works will need to be replaced to address adverse effects on private properties, amenity and local streetscape. Replanting within the property at 32 Normanby Road will be discussed and agreed upon with the land owner. If it is not possible to replant the same number of trees within the property, replacement trees will be planted in an appropriate location elsewhere within the CRL designation.
