Understanding local flood risks
We want to reduce the risks and impacts of flooding in Moreland. This means we need to adapt to weather extremes and our changing environment.
We recently completed a flood mapping study of all drainage catchments across Moreland to better understand risks and reduce the impacts of flooding in Moreland.
During average rainfall events, Council drains can capture the water and direct it into Melbourne Water drains downstream. This stops water from overflowing into streets, onto footpaths and into buildings.
A 1% Annual Exceedance Probability (AEP) event is a high-intensity storm that has only a 1% statistical chance of being exceeded in any one year. During a storm of this intensity, heavy rainfall can lead to stormwater flowing overland, damaging properties and infrastructure and creating costs for residents, businesses and Council.
While these events are rare, it’s important that natural hazards like flood risks are understood so that Council, residents and developers can plan to reduce any potential impacts. This is becoming increasingly relevant given the more intense rainfall that is predicted to occur due to climate change.
Moreland flood maps
We’ve prepared flood maps for the municipality and are preparing to designate the flood extent as area liable to flooding.
We’ve identified more than 7,500 properties in Moreland that are in areas prone to flooding during a high intensity rainfall event. The flood mapping study documents the flood risks that already exist in our city.
We are using this data to provide advice to property owners and developers when planning or proposing buildings and works to ensure they are constructed above the flood level and don’t block the flow of stormwater.
Please note, Melbourne Water is currently undertaking its own flood mapping study which is expected to be completed by May 2021. This means we are likely to update our flood maps in line with Melbourne Water data at this time.
Please note: these maps do not show flood extents that are already including in flooding overlays in the Moreland Planning Scheme. Find out if your property already has a flooding overlay.
Find out if your property is affected
You can find out if your property is identified as prone to flooding by searching your property address.
Flooding declaration under the Building Regulations 2018
We want to reduce the risks and impacts of flooding in Moreland, through new statutory controls. These new controls will apply rules to new buildings to help adapt to weather extremes and our changing environment. In March 2021 we intend to make a declaration under the Building Regulations (2018), which means further Council approvals will be needed for new building work.
Proposed Planning Scheme Amendment
After we have talked to our community about flooding and flood mapping, we will start a planning scheme amendment process to include the flood mapping information in the Moreland Planning Scheme. Including the mapping of flood prone areas in the planning scheme is our long-term plan for helping to manage flooding impacts across Moreland.
We’ll be inviting community feedback throughout this process and will contact you to let you know when this is happening. You can also FOLLOW this page to receive ongoing updates.
Talk to us
Help us plan to better manage flooding and drainage in Moreland by sharing your feedback and views about your property being included in an area subject to flooding. This discussion board will be open until Friday 5 March 2021.
Your suggestions and opinions will be valuable as we seek to implement the Study and do our part in protecting properties from flood damage.
If you are worried about flooding on your property have questions, or just want to provide us with more information on how your property has flooded in the past, you can book a 15 minute meeting with us on Tuesday 23 February and Thursday 25 February 2021.
Please call Urban Planner, Dimitrios Athanas on 9355 4270 or email DAthanas@moreland.vic.gov.au to book in a time.
