                 5.3       Lawful Point of Discharge
                 The existing lawful point of discharge is the southern boundary of the lot where runoff water exits the
                 lot as sheet flow into 22 Rifle Street. It is proposed that this lawful point of discharge is maintained post
                 development which is compliant with Section 3.9.1 requirements of QUDM. Pipe flows are proposed
                 direct to the drainage channel in Rifle Street with surface flows beyond the minor storm discharging to
                 22 Rifle Street conservation lot.

                 5.4       Flooding
                 The site is not identified to be impacted by flooding inundation event as per NSC Flood Hazard Overlay
                 Mapping as shown in Figure 7. Whilst the subject lot is not identified to be affected by the flood extents,
                 consideration of the surrounding flood conditions has been made as the adjacent lot to the south is
                 shown to be inundated during flood events. A flood search certificate was obtained which indicated that
                 the Defined Flood Event being the 1% AEP Climate Change flood level is 90.3m AHD. The building
                 levels have been designed to be above this minimum FFL (DFE +0.3m Freeboard).
