development, provide:

      a)   Independent verification from a suitably qualified and experienced professional to confirm
          that the parameters within the node for the device in MUSIC modelling have been tested and
          verified as per Stormwater Australia (2018) Stormwater Quality Improvement Device
          Evaluation Protocol. Version 1.2 December 2018 to achieve the predicted outcomes in the
          MUSIC model for the development. For the purpose of this information request, the suitably
          qualified and experienced professional must be able to demonstrate a minimum 10 years
          urban stormwater testing and modelling experience and be verified in writing by Stormwater
          Australia as having an appropriate reputation and track record within the stormwater industry
          to provide such independent advice.
      b) A MUSIC model along with plans that demonstrates how a biobasin or other vegetated
          stormwater quality treatment asset could be retrofit into the proposed development to
          achieve the required pollutant reduction targets in the event the proprietary device fails to
          perform under the local conditions.
      c) Agreement that any proprietary device would be considered as a trial only with the view to
          retrofit with a bio retention basin in the event the proprietary device fails to perform as
          required under the local conditions.
