Hybrid Question

How can green infrastructure reveal the story of water system at White Bay that benefits human well-being while accommodating massive future pedestrian flows?

WSUD features around The Bays Precinct

Balmain

Rozelle Pyrmont

Glebe

Promote awareness and knowledge of WSUD

Vision

Principles Baywater Activation

• Create recreation for local communities and visitors • Prevent the influence of sea level rise and water pollution from White Bay • Restore habitat for native creatures

Stormwater Activation

• Make stormwater visible, improve awareness and knowledge of WSUD • Establish stormwater recycling system to meet site water needs • Enhance site vegetation-density and biodiversity
