Code Amendment ID: 10042 State-Wide Flood Hazard

The State-Wide Flood Hazard Code Amendment seeks to use contemporary flood hazard modelling to update spatial application of the Code’s flood hazard overlays to realise greater consistency in flood hazard identification across local government area boundaries.

It aims to guide how development should address flood risk and be designed to keep people and property safe from floods.

The code amendment focusses on three aspects:

• more consistent and updated mapping: using the latest flood studies and data to update flood hazard overlay mapping, based on more contemporary standards and modelling, and applying the three flood hazard overlays more consistently across the state

• improved planning rules: introducing definitions and enhanced policies to make development assessments clearer and more consistent, and to align with national guidance

• faster process for future mapping updates: enabling a streamlined process to update flood hazard overlay mapping in the future as more contemporary flood studies and data become available.

This code amendment is the final stage of the State Planning Commission’s Flood Hazard Mapping and Assessment Project, which included delivering the Flooding Hazards Mapping Update Code Amendment and procuring new, detailed flood studies to update and enhance flood hazard mapping across the state.
