Flood information can be complicated. You should consult a qualified civil engineer with experience in hydraulics and floodplain management for advice about how flood information will affect your development.

You will also need to get a detailed ground level survey of your property from an independent registered surveyor. The results of this survey can be compared with the flood information from Council to determine the potential depth and extent of flooding on your property.

Information provided by Council

If flood information is available for your property, you will generally get up to four main types of information from Council. Note that some or all of these types of information may not be available for all properties:

1. Historical recorded flood levels
2. Flood level information, including
   1. Existing flood levels for 20% AEP (annual exceedance probability), 1% AEP and PMF (probable maximum flood) levels.
   2. Climate change flood levels
3. Flood risk precinct details if applicable
4. Other relevant information. This could include details of our flood studies, or any other available information.

Australian Height Datum

We provide flood level information relative to Australian Height Datum (AHD).

All flood levels, floor levels and ground levels are provided in metres AHD. This is the elevation (on the ground) of any object relative to sea level, which is 0 metres AHD.
