The proposal involves the construction of a stormwater management facility comprising a first flush dry basin (FFB) and wetland for the polishing treatment and attenuation of stormwater derived from existing and future urban development within the catchment.
The system will divert stormwater from Donalds Drain into the stormwater basins via a diversion weir in the drain and a new culvert under Gardiners Road.
Some property access may be affected. Traffic management will be in place on along Gardiners Road.
