We are currently reviewing our flood hazard maps based on updated flood modelling. The improved models use better technology to forecast rainfall, ocean boundaries and catchment characteristics.
Once completed, we will undertake a Flood Risk Assessment and a Feasible Alternatives Assessment Report. The Flood Risk Assessment will consider flood behaviour, future urban areas, zoning and land use, mitigation and immunity, and climate change. The Feasible Alternatives Assessment Report will assess and anticipate risk as well as how the proposed planning changes will mitigate the risks of flood hazards.
This work will inform proposed updates to the flood overlay code in the City Plan to improve the city's resilience to natural hazards.
The flood hazard overlay code will protect residents and their property by helping to mitigate flood risks through appropriate design and development provisions.
The proposed mapping and mitigations will be refined following community consultation to be conducted in 2022. The proposed City Plan update will then be submitted to the State government for consideration and assessment.
