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

  • f 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
