Flood Mapping
Council commissioned a number of flood studies for the Municipality, including:
- Urban areas of Sorell, Midway Point and the Southern Beaches 1% AEP flood mapping: broad scale flood modelling used to approximate flood extents through the Municipality’s overland flow paths at a whole of catchment scale.
They show the drainage lines and natural flood ways where flood water is predicted to travel through during a 1% AEP event.
The modelling has been done at a catchment wide level and provides an indication of potential hazards but may not be accurate at a property level. Seek independent advice for your site-specific flood risk.
The modelling identifies major flow paths during extreme events. It does not pick up localised nuisance flooding associated with undersized pits or pipes or localised road camber. It also does not pick up un-concentrated sheet flow, such as what occurs at the bush-urban interface. Just because your property is not within the mapped hazard extent does not mean you won’t be affected in a flood.
