Landslide hazard mapping
The City Plan includes a landslide hazard overlay map and code. The overlay map is based on landslide susceptibility mapping, which identifies where landslides may potentially occur, with moderate to very high ratings. The landslide hazard overlay code regulates development taking place on land with steep and unstable slopes, to help protect residents and their properties.
We are currently reviewing our landslide hazard exposure. The review will inform a proposed update to the landslide hazard overlay map and associated code to improve the city's resilience to natural hazards.
Draft mapping was previously presented to the community for feedback in 2020. As part of the review, further revised mapping is currently being developed. The proposed new mapping will use updated high-resolution photography and topography, as well as consideration of geological and other factors, to give a better representation of landslide risk.
The proposed landscape update will be delivered as part of the New Planning Scheme, and will be submitted to the State Government for consideration and assessment, followed by public consultation. Refer to the project timeline below for details.
