              2.3. Flooding
              The site was not identified as being impacted by flooding as per NSC Flood Hazard Mapping.

              3. Proposed Development
              3.1. General
              The proposal is for an industrial complex consisting of 17 industrial units. The proposed development includes
              two vehicle crossovers (separate entry and exit) on Action Street and an articulated vehicle exit only crossover
              on Leo Alley Road and on-site carparking. Water quality management is proposed to be achieved with a bio-
              retention basins on the Leo Alley Road frontage and a swale at the rear of car parking along the southern
              boundary.
              Refer to Appendix C for more details.

              3.2. Lawful Point of Discharge
              In accordance with the Queensland Urban Drainage Manual (2017) and NSC Water Quality and Drainage Code,
              stormwater is to be managed and discharged to a lawful point of Discharge (LPD).
              A discharge point is considered a lawful point of discharge if the following QUDM requirements are met:
                        The discharge at that location will not cause: an actionable nuisance (i.e. a nuisance for which the
                        current or some future neighboring proprietor may bring an action or claim for damages arising out of
                        the nuisance), or environmental or property damage; and
                        The location of the discharge from the development site is under the lawful control of the local
                        government or other statutory authority from whom permission to discharge has been received. This
                        includes parks, watercourses, drainage or road reserve, stormwater registered drainage easements,
                        or land held by local government (including freehold land).
              The development site currently discharges to the existing stormwater network in Acton Street, on the eastern
              side of the property. To maintain pre-development conditions and comply with the QUDM requirements
              mentioned above, the current discharge point will remain the lawful point of discharge for the proposed
              development.
