2      STORMWATER QUANTITY - Provide an amended water quality treatment
       system that utilises natural processes and materials, whenever possible, and is
       integrated into the development to enhance biodiversity and landscape benefits.
       Note that Council would be accepting of a bio-basin and/or bio-swales to achieve
       the required nutrient and pollutant reduction targets.




                2.1 Proposed MUSIC Model Concept

                All stormwater generated on the development site will be subject to water
                quality treatment via two proposed bioretention basins with a combined
                total area of 75m2, filter area of 60m2, extended detention depth of 200 mm
                and filter depth of 500mm.

                The efficiency of the proposed treatment train has been identified by the
                Model for Urban Stormwater Improvement Conceptualisation (MUSICX
                V1.1.0) developed by Monash University.

                A conceptual layout of the treatment train as input to the MUSIC Model is
                shown in Figure 5.4.1.b.

        The locations and details of the water quality treatment devices are shown on
        engineering drawings D01 and WQ01 at Appendix B.

        In Accordance with Noosa Regional Council, Water Quality analysis has been
        developed in accordance with Noosa Regional Council, State Planning Policy
        July 2017 (SPP) and the Queensland Water Quality Objectives (2009) for water
        quality objectives.
