Dear Glen,

RE: REC16/0014 – 28 Elkhorn Dr, Tewantin, RESPONSE TO INFORMATION REQUEST

    3. Refer amended SWMP report, in particular:
          a. The parameters have been adopted from the MUSIC Modelling Guidelines and
               the Healthy Waterways MUSIC Version 5 recommended parameters for Bio-
               retention basin nodes, which are as follows:
                        400mg/kg TN Content
                        50mg/kg Orthophosphate Content
                        200mm/hr Saturated Hydraulic Conductivity (amended from 180mm/hr)
               The most recent Version 6 recommended parameters for Orthophosphate are
               even less conservative compared to the Version 5 parameters, see link:
               http://healthywaterways.org/initiatives/waterbydesign/stormwater; However, we
               have continued with the Version 5 parameters for consistency with the
               previously submitted SWMP;
