 STORMWATER QUALITY
The following sections discuss the stormwater quality considerations for the construction and
operational phase of the development.


     4.1. Construction Phase

          4.1.1 Erosion and Sediment Control Measures
During construction, it will be 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.




           Figure 4.1 SPP 2017 Construction Phase Stormwater Management Design Objectives

A site-specific erosion and sediment control plan shall be prepared as part of a future submission for
Operational Works approval. Suitable erosion and sediment controls for the site may include:

     1. Sediment fencing along downstream of the work areas within the site to prevent sediment
        from leaving the construction area.

     2. A shakedown area is to be installed at the construction entry/exit to the proposed
        development area to minimise sediment being transported to and from the site.
