4        Stormwater Quality
Under State Planning Policy Part E – Water Quality (July 2017), developments are required to achieve prescribed
stormwater quality objectives where they exceed the defined thresholds for reconfiguring a lot or operational
works. The proposed MCU comprises a multiple dwelling development with works less than 2,500 m² and fewer
than six lots; therefore, formal post-construction stormwater quality treatment to meet SPP Part E pollutant
reduction targets are not required.

Although the development is not required to demonstrate compliance with the SPP post-construction water quality
objectives, the SPP emphasises the importance of protecting environmental values, applying water sensitive urban
design principles, and managing stormwater in a manner consistent with total water-cycle management. In keeping
with these principles, the development will adopt best-practice stormwater management measures to improve
water quality outcomes during the operational phase.

These measures include:

    •   Implementing a stormwater drainage layout that provides effective conveyance and attenuation of runoff,
        ensuring flows are safely and appropriately managed before discharge from the site.

    •   Provision of rainwater tanks to provide additional storage and enable reuse within the development.

The proposed stormwater strategy ensures that runoff is managed in accordance with best practice, supports the
environmental values of downstream receiving waters, and aligns with both the intent of the SPP and Council’s
stormwater management requirements.


4.1      Erosion and Sediment Control
An Erosion and Sediment Control Plan (ESCP) will be submitted as part of this application. The ESCP will outline
the specific measures to be implemented during the construction phase to minimise erosion and prevent sediment-
laden runoff from leaving the site or impacting downstream water quality.

The ESCP will be prepared in accordance with the IECA – Best Practice Erosion and Sediment Control Manual
(2008) and the requirements of the Environmental Protection Act 1994.

Typical ESC measures to be adopted during construction may include:

    •   Installation of sediment fences along downstream boundaries and around stockpile areas.

    •   Stabilised construction entry/exit points incorporating shakedown grids.

    •   Temporary diversion drains and bunds to direct runoff away from exposed areas.

    •   Sediment barriers at stormwater inlet pits.

    •   Dust suppression measures, including watering and covering of stockpiles.

    •   Progressive stabilisation and rehabilitation of batters and disturbed areas.

The principal contractor will be responsible for implementing and maintaining ESC measures in accordance with
the approved ESCP, including routine inspections and necessary maintenance throughout the construction period.
