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


     4.1. Construction Phase

          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. A range of best practice sediment and erosion controls
should be implemented on the development to ensure negative impacts to the downstream receiving environment
are mitigated.

The works will involve only localised works to provide for drainage and driveway upgrades, therefore best practice
erosion and sediment control principles are considered suitable for the site to achieve the desired outcomes of
Appendix 2 of the SPP (DERM, July 2017), which are shown below in Figure 4.1.

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.
