Help us better plan for floods and coastal hazards

Frankston City Council is working with Melbourne Water and the Department of Energy, Environment and Climate Action (DEECA) to map where flooding and coastal hazards have occurred across Frankston City.

With up-to-date information on the extent of flooding and coastal hazards, we can better plan and manage risks, and build the resilience of our City.

How can you get involved?

Online map

The information we receive during our Phase 1 community engagement will be added to existing Council, DEECA and Melbourne Water data to create comprehensive flood and coastal hazard maps.

These maps can be used to inform planning controls, emergency management, community awareness and mitigation works where possible. This will help ensure future developments are better designed to avoid flooding and hazard impacts.

How do we define a 'flood' and a 'coastal hazard'?

What is flooding?

Flooding and rising water levels are a natural occurrence across Victoria. All Councils have a role to play in building their community's resilience. This is in partnership with water authorities, emergency services and other government bodies.

Flooding can be influenced by factors including:

  • Severe rain events.
  • Land topography.
  • Capacity of the drainage system.
  • The extent that water can be absorbed into the ground.

In a Council context, flooding is defined as a natural yet persistent gathering of stormwater that disturbs the intended use of infrastructure and properties.

For this project, we have categorised different types of flooding in the following ways:

  • Flooding on public land

    Includes flooding on streets, path and reserves.

  • Flooding on private land

    Including flooding that enters private land and/or homes.

What is a coastal hazard?

Stretching from Kackeraboite Creek in the south to Keast Park in the north, our 9.5km of coastline is renowned as the most pristine and accessible stretch of foreshore on Port Phillip Bay.

However, natural processes such as erosion and inundation continually shape our diverse and dynamic coastline. We refer to these processes as coastal hazards when they could have an adverse impact on environmental, cultural, social and economic values along the coast.

Coastal hazard exposure occurs periodically across the coast, and is projected to increase with changes in wave action, storm activity and sea level rise associated with climate change.

Council is taking a strategic approach to coastal hazard risk management and adaptation. Learn more about our Coastal Resilience 2100 project, and more detail about the coastal hazards that impact our coastline here.

Types of coastal hazard

  • Erosion

    Coastal erosion is the process of winds, waves and coastal currents shifting sediment, for example sand, silt, or soil away from a localised area of the shoreline.

    Areas around Port Phillip Bay are prone to coastal erosion. Rising sea levels and bigger storms also mean waves can reach further onshore, which is likely to cause more erosion.

  • Inundation

    Coastal inundation is flooding of low-lying land by seawater.

    Some lower lying land around Port Phillip Bay is prone to coastal flooding.

    With sea level rise, areas flooded by the sea during storms may become bigger.

  • Cliff instability

    Like all coastal environments, cliffs are dynamic features subject to cracking, erosion and landslips. They are influenced by geological factors, weather events, wave action and erosion, groundwater seepage, vegetation changes, and human activity. These pressures often work in combination, making cliff instability an ongoing and complex issue.

    It can be hard to accurately predict when landslips may occur. There is often no warning and the volume of material that falls can be very large.

Roles and responsibilities in water management

  • Property Owners

    Property owners are responsible for:

    • Taking reasonable measures to ensure their properties are protected from the larger storm events
    • Ensuring all private pipes, gutters and downpipes are regularly maintained and kept clear
    • Reporting any issue that they observe with drainage to Council
    • Understand their risk exposure based on available information, and act responsibly in light of that information.
  • Department of Energy, Environment & Climate Action

    DEECA works to protect and enhance our coastline and its waters to support business, tourism, recreation, wellbeing and biodiversity. It's programs include:

    • Modelling and analysis to better understand current and future coastal hazards.
    • Monitoring waves and coastal changes at priority sites.
    • Supporting community groups and volunteers to protect and enhance Victoria's coastline.
