Hobsons Bay City Council

Are you at risk of flood?

Altona and Seaholme are coastal suburbs on relatively flat terrain. This makes the stretch of land near the bay susceptible to flooding during high intensity rain or storm events.

When a storm occurs during a very high tide and southerly winds, sea water can come over the flood wall next to the beach. This is called ‘storm surge’ flooding and results in Beach Street and The Esplanade flooding frequently; especially near Sargood and Bayview street.

It can also lead to potential flooding of underground car parks. Flash flooding can also be an issue for the Altona/ Seaholme area, where a high amount of rain occurs and can’t drain away fast enough. This can especially occur during high tides where the drains can struggle with the push of water back from the ocean combining with the flat terrain of Altona and Seaholme.

Areas that can be affected include:

• McIntyre Drive

• Civic Parade all the way to McIntyre Drive

• The area between Civic Parade and the railway line from Seves Street

• Areas south of Linnet Street, either side of Mulga/ Manning Street. Finally, the Altona and Seaholme area is also at risk from flooding during longer rain events where Laverton Creek, Cherry Lake and Kororoit Creek could flood.

• Green areas and levees in the area provide some protection for properties, but the Altona/ Racecourse road and sections of the Werribee railway line may be flooded if the Kororoit Creek overflows.
