4.4         Stormwater

            Water Quality Objectives are mandated by the State Government. They are
            identified in the State Planning Policy 2017 (SPP). The SPP includes the
            following triggers to that are required to achieve water quality objectives:

            “(2) Reconfiguring a lot for an urban purpose that involves premises 2500m2
            or greater in size and will result in six of more lots”.

            Based on the above, there are no water quality objectives that are required to
            be achieved for this development. However, it is noted that a bio-retention
            basin will be provided at the northeastern corner of the subject site to aid in
            maintaining stormwater quality for the subject site.

            Stormwater for any development on proposed Lot 1 and 2 will have a lawful
            point of discharge connected to the bio-retention basin. Stormwater from the
            new road will be captured and discharged into the bio-basin. Lot 3 will be
            provided with a lawful point of discharge in the south east corner of the Lot
            which will drain to the drainage reserve beyond (see Appendix E for details).

            The proposed measures will provide a significant amenity improvement to
            properties along the adjoining Dianella Court by providing additional
            infrastructure for stormwater discharge and a bio-retention basin for
            stormwater quality management as opposed to sheet flowing to the east under
            the current scenario.
