             3. Stormwater Quantity and Drainage
             The proposed development will result in a slight reduction in the overall level of
             imperviousness of the site so overall stormwater runoff volumes and flowrate will not be
             increased and stormwater detention is therefore not required in order to ensure ‘non -
             worsening’.

             In terms of drainage, the key issue to ensure no impacts from the development is to include
             allowance from the existing external catchment from Ernest Street to continue to drain
             through the site. This has been addressed in the SWMP presented in Figure 2.1.
