            4. STORMWATER QUALITY
            The following sections discuss the stormwater quality considerations for the construction
            and operational phase of the development. Refer to Appendix A Proposed Development
            Plans for the proposed stormwater drainage layout plan.

                        4.1.1 Erosion and Sediment Control Measures

            During construction, it is necessary to manage stormwater run-off to avoid potential
            contamination of downstream waterways from sediments and other pollutants from the site.
            Best practice erosion and sediment controls shall be installed to minimise the discharge of
            potential contaminants from the site, in accordance with the objectives of Appendix 2 of the
            SPP (DERM, July 2017) shown below in Figure 4.1.

            Appendix A (Proposed Development Plans) contains the site-specific erosion and sediment
            control (ESC) Plan prepared for the development. The measures proposed for the site
            include:
