Trees to be removed within the designation
Mitigation Measures A replanting plan will be identified in a future urban design plan 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 inclusion of 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 for a period of five years for specimen trees and three years for all other landscape planting

Project Overview
Relevant Regulatory Requirements Technical Reporting Requirements • Auckland Council Regional Plan: Sediment Control 2001 • Auckland Council Regional Plan: Air, Land and Water 2013 • Proposed Auckland Unitary Plan – Decision Version 2016 (PAUP) Controls and Monitoring • Auckland Council Technical Publication 90: Erosion and Sediment Control Guidelines Referenced Reports • Water Quality Assessment (CRL-SYW-RME-000-RPT-0071) • Contamination Delivery Work Plan (CRL-SYW-RME-000-RPT-0073)
Sediment and Erosion Control Principles • Stabilised surfaces • Isolation of Construction Support Areas (CSAs) • Diversion of clean surface flows away from sites • Management of surface flows within site • Minimising storage of excavated materials
• Settlement tanks • Protection of stormwater inlets
• Super silt fences to stockpiles • Water quality monitoring
