We recently reviewed our flood maps based on updated flood modelling. The improved models use better technology to forecast rainfall, ocean boundaries and catchment characteristics.
We have also prepared a Flood Risk Assessment and a draft Feasible Alternatives Assessment Report. The Flood Risk Assessment considers flood behaviour, future urban areas, zoning and land use, mitigation and immunity, and climate change. The draft Feasible Alternatives Assessment Report has assessed and anticipated risk as well as how the proposed planning changes might mitigate the risks of flood hazards.
This work has informed the development of proposed updates to the flood overlay code in the City Plan to improve the city's resilience to natural hazards.
The flood risk overlay code will protect residents and their property by helping to mitigate flood risks through appropriate design and development provisions.
The proposed amendment is currently with the State government for consideration and assessment. Public consultation is anticipated to be undertaken next year.
