 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 has been prepared for the development making use of a range of
suitable erosion and sediment controls, including:

     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.
