                      a.      stormwater quality treatment devices of a size and location generally in accordance
                              with those shown in Stormwater Management Plan, prepared by MPN Consulting,

                              i.       demonstrate that Bio basin 1 is able to gravity drain to the existing stormwater
                                       infrastructure on site. The outlet pipe grade must be a minimum of 0.5% to
                                       ensure the bio basin is free draining.
                              i.       are designed generally in accordance with the Bioretention Technical Design
                                       Guidelines (Water by Design, 2012)
                              ii.      are designed, where applicable, generally in accordance with IPWEQA Standard
                                       Drawing No. DS-073, DS-075, DS-076, and DS-078

                      about the function of the bioretention device(s). The dimensions, standard, presentation and
                      location of the educational signage must be in accordance with an Operational Works
                      approval.
               60.    All stormwater quality treatment devices must be maintained in accordance with the Water

                      Operational Works drawings for the stormwater quality treatment system and detailed life
                      cycle costing of the system must be attached as an addendum to this document. Records of
                      all maintenance activities undertaken must be kept and made available to Council upon
                      request.
               61.    Any proposed Community Management Statement required for the development must
                      include Water by Design (2009) Maintaining Vegetated Stormwater Assets (Version 1) and
                      must include the full cost of maintaining the system in accordance with Water by Design
                      (2009) Maintaining Vegetated Stormwater Assets (Version 1). The cost of maintaining the
                      system must be included in the proposed levies for each unit owner.
                      Stormwater Drainage
