 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 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.

As the area being developed is below 2,500m², the development’s construction will be managed
using best practice erosion and sediment control principles in line with 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. Provision of an on-site sedimentation basin to reduce sediment concentrations from site
        discharge.
