                      e.      pram crossings on either side of Spotted Gum Court and where required on the new
                              road
                      Condition 12 is imposed pursuant to s145 of the Planning Act 2016 being non-trunk

                      Stormwater Quality
               13.    Stormwater Quality Treatment must generally be in accordance with the Integrated Water
                      Management Plan revision 3 16 Lot Reconfiguration at Pearsons Road, Cooroy for Noosa
                      Council April 2021, except as follows:
                      a.      Gross Pollutant Traps are not approved. Alternative measures to achieve the pollutant
                              reduction predicted for the GPT’s must be provided.
                      b.      The first application for Operational Works submitted to this approval must include an
                              amended Integrated Water Management Plan (IWMP). The amended IWMP submitted
                              for approval must include an updated MUSIC model prepared in accordance with the
                              Healthy Land and Water, Water by design Music Modelling Guidelines, which
                              demonstrate the minimum pollution reduction targets of 80% reduction in Total
                              Suspended Solids, 60% reduction in Total Phosphorous and 45% reduction in Total
                              Nitrogen are achievable by the detail design, required by this approval.
                      c.      Pollutant reduction target calculations must include pollutant reductions obtained for
                              Catchment F
                      d.      Appendix 1 of the amended IWMP must clearly outline special design elements, such
                              as roof water connections to kerb required by any building or plumbing design to
                              achieve the minimum pollutant reduction target for the development.
                      e.      Deleted.
                      f.      Deleted.
               14.    The Operational Works Application must demonstrate that the design for water quality
                      treatment features are consistent with the technical design guideline published by Healthy
                      Land and Water, Water by Design for the feature. (eg. For Bioretention Basins: Bioretention
                      Technical Design Guidelines (October 2014) and for Wetland Systems the Wetland
                      Technical Design Guideline (May 2017).
               15.    Permanent educational signage provided in must be erected to educate the residents of the
                      development about the function of the bioretention device(s). The dimensions, standard,
                      presentation and location of the educational signage materials and colour schemes must be
                      consistent with Noosa’s Design Principals and in accordance with an Operational Works
                      approval.
                      Stormwater Quantity and Flooding
               16.    In conjunction with the submission of a development application for Operational Works,
                      provide final design details for the stormwater detention system and updated modelling. The
                      detention system is to be based generally on the approach documented in Flood Assessment
                      Report Revision 3, prepared by Callaghan and Toth, dated April 2021 and is to address the
                      following points:
                      a.      Any updates required for consistency with the amended approved Integrated Water
                              Management Plan.
                      b.      Updated modelling is to be based on basin routing procedures (as described in QUDM
                              Section 5.6.2), with full details of the basin outlet structure provided.
                      c.      Analysed durations, (for which no increase in peak flows is to be achieved for the post
                              development condition compared to pre-development), are to include the critical
                              durations for the waterway through the urban areas of Cooroy downstream of the site.
