                  MUSIC MODEL LAYOUT
                  A MUSIC model has been created with three conceptual Legal Point of Discharge (LPOD)
                  nodes in order to demonstrate that the site meets the pollutant removal targets as specified by
                  Council and the State Planning Policy. Separate land use types have been modelled to
                  represent; roof water runoff, runoff from hardstand impervious areas and runoff from grassed or
                  otherwise pervious areas within each catchment. Appropriate percentage impervious factors
                  have been applied to all nodes based on the proposed design detailed within the Engineering
                  Drawings presented in Appendix B.

                  Four separate bio-retention areas across thee catchments form the basis of the treatment train
                  and is represented in the model with appropriate areas and volumes. A diagrammatic view of
                  the MUSIC model layouts is presented in Figure 6.3.
