Flood risk areas explained

Risk area Common description Technical description
High risk area
  • Frequent flooding is common
  • Near the main river and creeks where water flows during a flood, including overflow from drainage
  • This area will see the fastest flowing and deepest water and cause a significant risk to life

High hazard flood area within the 1% annual exceedance probability (AEP) (1:100)
Medium risk area
  • Frequent flooding will be rare
  • Where the flood water goes once the creek/river areas overflow
  • In rare floods these areas have the potential for deep and fast flowing water

Medium and low hazard area in the 1% AEP (1:100)
Low risk area
  • Flooding is extremely rare
  • Generally, away from the river or creek and higher up
  • If a flood affects these areas it will cover a large area with dangerous water in many places

Area from the 1% AEP (1:100) up to the Probable Maximum Flood

Everywhere else

Not expected to flood but there still could be local incidents water running off the land and of street drainage not coping with rainfall amounts.

Area outside the Probable Maximum Flood. There may still be isolated impacts from local overland flow.

Planning Certificate

You can apply for a Planning Certificate (otherwise known as a Section 10.7 certificate), by visiting this page. This certificate provides a range of planning information applicable to the property, potentially including planning controls relating to flooding.
