RFI (rec. 5.06.26) 2567 - Appendix B - Site-Based Stormwater Management Plan (SBSMP) (Ver. 2)

The following are typical treatment measures that will be implemented, as required, before the
commencement of any construction works. Detailed erosion and sediment control procedures
are to be undertaken in accordance with the IECA Best Practice Sediment & Erosion Control
and the Erosion and Sediment Control drawings lodged as part of an Operational Works
application.
          sensible site planning
          diversion of up-slope water (where appropriate)
          stabilised site entry/exit point
          minimisation of site disturbance and duration of disturbance
          installation of sediment control along the lower edge of the site
          appropriate location and protection of stockpiles
          early connection of roof water downpipes
          trap on-site runoff from tool, paint and concrete washing and brick, tile and concrete
           cutting
          continual monitoring and maintenance of all control measures
          compaction of backfilled trenches
          revegetation and stabilisation of the site
          development and implementation of Erosion and Sediment Control Plans when
           appropriate.

3.2       Post-Construction Phase

During the post-construction phase, water quality objectives will adhere to the standards in
Table SC6.7.6.1 of the Noosa Shire Council Planning Scheme and Table B of Appendix 2:
Stormwater Management Design Objectives, Part G, QLD SPP (2017), as provided in
Appendix B of this report. Targets for this site are covered under the limits for South East
Queensland:
          Total suspended solids (TSS):          80% reduction from unmitigated development
          Total phosphorus (TP):                 60% reduction from unmitigated development
          Total nitrogen:                        45% reduction from unmitigated development
          Gross pollutants (>5 mm):              90% reduction from unmitigated development
