Sea level rise is projected to increase over the next 100 years as a result of climate change, worsening coastal inundation. This will increase the number of properties impacted and the depth of flooding.
Our 2017 Planning for Sea Level Rise Guidelines were previously used by us to assess development proposals in flood-prone areas (including coastal inundation), to keep people safe and minimise property damage. We are currently updating these guidelines and have removed them from our website while this takes place.
Please refer to:
- Melbourne Water’s Interim Development Assessment Principles, found below
- the Victorian Government’s Guidelines for Development in Flood Affected Areas (2019)
- the Victorian Government’s Planning Practice Note 53 Managing Coastal Hazards and the Coastal Impact of Climate Change (2023) .
You can still apply to us online for property flood level information.
Updating the guidelines
In the past, there were two planning horizons for state planning policy and our sea level rise guidelines: 2040 and 2100. In 2021, state planning policy was amended to remove the 2040 planning horizon. This was due to the long-term nature of land use planning decisions and the long life of buildings.
In response to this change, we will no longer be assessing development using the 2040 planning horizon. Our guidelines are being updated to reflect this change, and expected to be finalised in 2024.
