Merri-bek City Council has redesignated updated stormwater maps under the Building Regulations 2018. The new stormwater maps came into effect on 30 November 2023. You can use the interactive map to confirm whether your property is affected by the stormwater maps.
In Merri-bek we have regional and local drainage catchments. Melbourne Water manages the (larger) regional catchments and Council manages the (smaller) local catchments. In the regional catchments:
- Stormwater comes from the local catchments and flows into rivers and creeks.
- Melbourne Water has regional (main) drainage infrastructure.
- Mapping for the regional stormwater flow paths has been included in the Merri-bek Planning Scheme and is shown by the Special Building Overlay, Schedule 1 (SBO1). These maps are on the Victorian Government's Planning website.
See if your property is affected by stormwater overland flows
To determine if your property is affected by stormwater overland flows during a 1% AEP rainfall event in a:
- local drainage catchment, you can search your address on our Stormwater mapping page.
- regional drainage catchment, you can look at the existing SBO1 maps in the Merri-bek Planning Scheme on the Victorian Government's Planning website and go to Melbourne Water's website for more information.
We will work with you by using a two-step approvals process when you are planning any building works:
