Flood Mapping in Merri-bek

Enter your address
Search your address to see whether your property is in an area prone to flooding during high-intensity rainfall (1% Annual Exceedance Probability*).

We've completed a flood mapping study of all drainage catchments across Merri-bek. This study will help us better understand local flood risks and what this means for building on your property.
The flood mapping study provides us with data that will help us to advise property owners and developers planning or proposing buildings and works. We want to ensure buildings and works are constructed above the flood level and don’t block the flow of stormwater. 

Please note: these maps do not show flood extents that are already including in flooding overlays in the Merri-bek Planning Scheme. Find out if your property already has a flooding overlay. 


My property is identified as prone to flooding, now what?  

Once these new controls are implemented, we’ll work with you via a two-step approvals process when planning any building works: 

  • Step 1: Lodge a Flood Level Application for preliminary advice. 
  • Step 2: Once the design is finalised, lodge a Report and Consent application  
Anyone selling or buying property will be notified of the flood risk at the time of purchase when they seek a Section 51(2) Property Information Certificate from Council.

If you are worried about flooding impacts on your property, have questions, or just want to provide us with more information on how your property has flooded in the past, please contact Council’s Customer Contact Centre on 9240 1111 or info@moreland.vic.gov.au.

* A 1% Annual Exceedance Probability (AEP) event is a high-intensity storm that has only a 1% statistical chance of occurring in any one year.  During a storm of this intensity, heavy rainfall can lead to stormwater flowing overland - damaging properties and infrastructure, which creates costs for residents, businesses and Council.
