These Advisory Notes do not form part of this approvai or the conditions attached thereto.
' The. following Advisory Notes are intended to provide guidance to the applicant where
necessary and inform the applicant of actions that Council may take with respect to the

development site or the approval:

CIVIL ENGINEERING

1. In this document, an effectively stabilised surface is defined as one that does not:
1.1." ‘have visible evidence of soil loss caused by sheet, rill or gully erosion or
1.2. lead to sedimentation, or
1.3. - lead fo water contamination.

2. Diverting clean stormwater runoff into a sediment basin is an inferior option to diverting
clean stormwater around or through the site because it will cause an increase in the
volume and frequency of contaminated releases from the sediment basin. For this
reason, diverting clean stormwater into a sediment basin is not acceptable unless the
proponent demonstrates that diverting clean stormwater around or through the site is
not feasible. : —

3. Compensatory controls are erosion controls, flow controls and sediment controls which
compensate for the lack of sediment basin and are applied such that the type, timing,
placement and management of controls. minimise the potential for water contamination
and environmental harm. This is primarily achieved by reducing the risk of erosion and :
subsequent sediment release, for example by turfing or mulching and managing
concentrated flows in the area. .

4. Research has shown that sediment basins designed on a “batch” or total storm capture
approach are only capable of treating a small percentage of the annual runoff volume
without basin size becoming excessive. Innovation in sediment basin design to
incorporate continuous flow treatment is likely to occur in the future and as this
technology becomes available in-best practice guidelines it is required that this
technology be adopted where a better water quality outcome will result. In the interim
the minimum basin size is as specified in the condition.
