Objectives:
1. Protect and enhance natural water systems within urban developments
2. Integrate stormwater treatment into the landscape + maximise the visual and recreationalamenity of developments
3. Protect water quality
4.! Reduce run-off and peak flows
5. Add value while minimising costs of drainage infrastructure costs and other structural solutions
