5.7.         Mitigation Measures
Based on the findings discussed in Section 5.5 and 5.6, it is considered that no stormwater quantity
mitigation measures are required as the site demonstrates no increase in peak flow rate, and the
insignificant increase in runoff volume occurs much sooner than the critical storm associated with the
major flood event for the catchment.
