Trees and Vegetation Delivery Work Plan
Doc. No. CRL-PAT-ENV-CON-PLN-001034
Revision: 05, Date: 21March 2016
5 MITIGATION MEASURES
Due to the requirement to remove trees throughout the Project footprint, an adverse effect on the local treescape would result if no mitigation measures are implemented. In addition, mitigation measures will be put in place to protect trees labelled G5, G7, X1, X2 and T9 which are not required to be removed.
5.1 TREES THAT ARE REQUIRED TO BE REMOVED
Replacement planting will be required for all trees that are required to be removed, as identified in Figure 3. A replanting plan will be identified in the Project Urban Design DWP and will include (but may not be limited to) the following:
Replanting of trees at least 1:1 ratio Trees to be 4-5m height in ground, with single clear trunk to minimum 1.6m, trunk to be no less than 50mm in diameter at 300mm above ground, in good robust health with suitably sized root ball
Area reinstatement
The opportunity to include appropriate native species in the replacement and landscape plantings.
Documentation of the input from the Auckland Council Parks Department with regard to tree species / vegetation selection, tree pit construction and positioning of replacement trees
An outline of the maintenance periods and responsibilities (i.e. the Requiring Authority for a period of five years for specimen trees and 3 years for all other landscape planting)
Consultation outputs (refer Section 6 of this TV DWP)
5.2 TREES THAT ARE NOT REQUIRED TO BE REMOVED
5.2.1
Arboricultural Monitoring
A suitably qualified and experienced arborist will be engaged to act as the Site Arborist for the Project. The Site Arborist will be available (as required) to address any ad hoc issues that may arise in relation to tree health. The Site Arborist shall also undertake regular Arboricultural Site Reviews (ASR) at a period of no less than once every two months during any period for which works are to take place within 4 metres of the dripline of any tree(s) which will not be removed as part of the construction works The ASR shall provide an opportunity to assess tree health of each of the trees which are to be retained, assess tree protection measures where provided, as well as providing general guidance to direct the preservation of tree health during the course of works.
The initial ASR should be undertaken at least 10 working days prior to the first commencement of work within 10 metres of any tree which is to be retained. The Site Arborist will prepare a Tree Management Checklist to be issued to the Environmental and Sustainability Manager (ESM) during the initial arboricultural site review to enable continuous monitoring of tree health in the intervals between each arboricultural site review The Tree Management Checklist should include (but may not be limited to):
Direction for assessing general tree health
Direction to identify deterioration of tree health

Revision: 05, Date: 21March 2016
The ESM will undertake periodic monitoring of tree health as prescribed by the Tree Management Checklist at periods of no less than once every 14 days, and evidence of this monitoring should be provided to the Site Arborist during each ASR. If the ESM identifies evidence of declining tree health, the Site Arborist should be engaged to provide assistance in determining the cause of such deterioration and provide direction where appropriate.
5.2.2 Tree Specific Measures
The following sections outline the proposed mitigation measures to be employed for the trees identified as remaining in Figure 3 and Table 3
5.2.2.1
ID T6
The Pohutukawa Tree identified at T6 (Figure 4) is not expected to be affected by the Project and therefore will require no additional protection. It will remain in a public pedestrian space.
Tree health will be monitored regularly during construction. This will be undertaken in accordance with the periodic ASR and the regular tree health monitoring undertaken by the ESM.
Figure 4 ID T6
5.2.2.2
ID G5
The group of trees identified as G5 (Figure 5) are not expected to be affected by the Project and therefore will require no additional protection. They will remain in a public pedestrian space.
Tree health will be monitored regularly during construction. This will be undertaken in accordance with the periodic ASR and the regular tree health monitoring undertaken by the ESM.

Revision: 05, Date: 21March 2016
5.2.2.3
ID X1 and X2
The trees identified as X1 and X2 (Figure 6) sit on the periphery of the Project footprint. Pruning or tying back of branches that could interact with passing traffic and site offices is necessary. Any tree pruning will be kept to a minimum and will be undertaken by a qualified and experienced Arborist. Whilst not envisaged to occur, should extensive pruning be required to remove the tree canopy of X1 or X2 that negatively affects their visual character, replacement planting may be provided as outlined in Section 4.1
A protection fence will be erected between the construction works and the trees, however the trees will not be totally ring fenced as they remain in a public pedestrian area.
Tree health will be monitored regularly during construction. This will be undertaken in accordance with the periodic ASR and the regular tree health monitoring undertaken by the ESM.
5.2.2.4
ID T9
The tree identified as T9 (Figure 7) sits on the periphery of the Project footprint and therefore will be mainly unaffected by construction works. However, pruning will be required to remove overhanging branches that could interact with passing construction vehicles. Any tree pruning required will be kept to a minimum and will be undertaken by a qualified and experienced Arborist.
Tree health will be monitored regularly during construction. This will be undertaken in accordance with the periodic ASR and the regular tree health monitoring undertaken by the ESM.

Damage to trees can therefore only occur above surface level. Damage caused to trees above surface level will be obvious such as broken branches. Therefore a qualified arborist is not required The closest tree to the excavation works is T9, and there is at least 5m from the face of the trench excavation to the closest point of the T9 canopy.

- It is unclear from the TV DWP why the small magnolia (T10) needs to be removed but the much larger alder (T9) is capable of being retained.
14-16, 18 5.2.2, Table 3 and Figure 3
- The canopies of these trees encroach into the carriageway quite significantly. An understanding of the pruning requirement would be helpful. IF the trees need to be pruned back to the kerb line for example, their visual character will be compromised and their contribution in this setting would be in question. A good long term outcome could be reached by removing them should extensive pruning be required and providing replacements. This would need to be undertaken through liaison with AC Parks.
T10 is required to be removed in order for vehicle tracking to be maintained on Wolfe Street. T9 does not interfere with vehicle tracking and can therefore remain.

14-16 Table 3 and Figure 3
- Tree G3 (pohutukawa x4). Three of these trees are potentially suitable for relocation. One has rotated at its base and is unlikely to prosper.
General - There needs to be some comments / recommendations in relation to the elms (T13) and the requirements under The Biosecurity Act (1993). How will this material (wood and soil) be dealt with in order to comply with these provisions?
General - Aside from protective fencing, other tree protection measures such as caring for roots are absent from the TV DWP. Is this level of detail required at this stage? Appointing an arborist before construction begins to coordinate works around trees seems appropriate. He / she could most likely prepare a site specific tree protection plan if required.
No. CRL-PAT-ENV-CON-PLN-001034
Revision: 05, Date: 21March 2016
The four Pohutukawa identified as G3 do not affect this Project (C2) but are being removed by Precinct Properties. As such, the potential relocation of these trees and mitigation is the domain of Precinct Properties.
No change to this TV DWP
Connectus confirms that the six Elm trees identified at T13 are not required to be removed and therefore specific provisions to remove Elm trees as part of the Project are not necessary.
Section 5.2.5 added, detailing the mitigation measures required for T13
The trees to be retained (T6, G5, G7, X1,X2, T9, T27-T30) will not have their roots disturbed due to the sufficient distance between the trees and the Project works. As a result, appointing a qualified arborist will not add additional value.
Since damage to trees below ground cannot occur, the only protection required for trees is above ground i.e. Protective fencing.
