Know Your Flood Risk


FloodSmart Parramatta now provides flood risk information for the Upper Parramatta River which includes the upstream areas from Parramatta CBD. This will allow you to understand if your property is at risk of flooding and how frequent or significant floods could be.

Other areas will be made searchable as new data becomes available.  If you live outside of this area you can check your properties section 149 certificate or apply for a Flood Enquiry Application.

Flood Risk areas explained

  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.

Don't forget, even if your property is not in the high, medium or low risk areas you may still see the impact of floods in your area. These could include:

  • deep and fast flowing rivers and creeks
  • closed roads or bridges
  • impacts on travel routes
  • submerged fields or parks
  • flooding to other homes, schools or businesses.
