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.
Since modelling was completed in April 2022, we 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 anticipate 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 City Plan amendment will be submitted to the State government for assessment in mid-2023.
Model rainfall and flooding across the Gold Coast and develop city-wide flood maps for planning and insurance
Use flood maps to undertake a city-wide flood risk assessment
Use flood risk assessment to consider land use planning options
Finalise draft City Plan major update for State Government review in late-2023
When endorsed by the State Government, undertake community consultation 2024
Following endorsement by Council and the State Government, adopt flood amendments into the City Plan
