Attachment 7B - Site Based Stormwater Manamgment Plan by ADG

                                                                  RACV Noosa Resort: 94-142 Noosa Drive, Noosa Heads

                                                                           ADG Ref: 22366 C R10 Rev04 14.12.22.docx

                                                                                                     December 2022

             Maximise retention of existing vegetation to reduce soil disturbance and provide filter strip
             treatment for runoff;

             Install construction entry and exit shakedown areas;

             Sediment fences are to be installed on the downstream boundaries of the subject site; and

             Install dust control measures as required.

          All erosion and sediment control measures are to be designed and installed in accordance with IECA
          Guidelines. Further details regarding the proposed erosion and sediment control measures will be
          provided during the detailed design phase of the development.

          Further to the above considerations, it is the developments intent to limit ground disturbing activities
          to a minimum. Other than a portion of the carparking area, all structures and footpaths are proposed
          to be suspended over the existing surface.

 6.2.2    Bulk Earthworks Phase

          During the bulk earthworks phase, the following erosion and sediment control measures will need to
          be installed in addition to the aforementioned measures (Pre-Development Phase) to ensure there
          is minimal disturbance to downstream receiving water bodies:

             Construction chutes to control runoff over earthworks batters;

             Construction of temporary bunds at the top of all earthworks batters to ensure runoff is directed
             away from exposed batters;

             Sediment basins to be constructed at low points within each stage of the proposed development;

             Sediment fences to be installed on the downstream side of any stockpiles; and

             Stabilisation of all batters upon reaching the finished earthworks levels.

          All erosion and sediment control measures are to be designed and installed in accordance with IECA
          Guidelines. Further details regarding the proposed erosion and sediment control measures will be
          provided during the detailed design phase of the development.

 6.2.3    Construction Phase

          During the construction phase of the development, there is a risk of sedimentation transport due to
          disturbed land. The following erosion and sediment control measure will need to be installed in
          addition to the aforementioned measures (Pre-Development and Bulk Earthworks Phases) to ensure
          there is minimal disturbance and the quality of runoff is maintained to an acceptable standard:

             Construction of temporary diversion drains to divert water to sediment basins;
             Construction of temporary diversion drains to divert water to protect bioretention and treatment
             devices as required;
             Sediment barriers to be installed on all entrances to newly constructed stormwater infrastructure
             (i.e. gully pits);
             Sediment fences to be installed on the downstream side of any stockpiles and batters; and
             Re-vegetation of all disturbed areas within two (2) weeks of completion.
