From Department of Energy prepares to bolster Barwon River levee defenses

What could the Department of Energy's levee strengthening efforts mean for the city?

Possible What happens if… A possibility worth considering, not a forecast.

Coastal flood risks may increase for the city despite levee defense plans The Department of Energy, Environment and Climate Action is investing $250,000 to study and plan flood mitigation for the Riverview Caravan Park, which is protected by a vulnerable levee along the Barwon River. This levee protects coastal communities, including those in the catchment area of the city. The city is already managing extensive stormwater flooding risk across its suburbs, despite managing over 2450 kilometres of drainage infrastructure. If the levee defenses prove insufficient to counter threats like sea level rise, the city could face increased pressure to fund major infrastructure updates and manage higher flood risks.

The facts so far

As reported. Each one links to where it comes from.

  • The levee protects the Riverview Family Caravan Park in Ocean Grove, which hosts about 500 accommodation sites.smh.com.au
  • The levee is forecast to be fully inundated by 2100 under current sea level rise scenarios.smh.com.au
  • The Department of Energy, Environment and Climate Action received $250,000 in federal government funding for a flood study and adaptation plan.smh.com.au
  • The city manages more than 2450 kilometres of drainage infrastructure.smh.com.au

Why it matters

The vulnerability of the levee and the increasing threat of coastal inundation pose a significant long-term risk to the coastal communities and infrastructure within the city's catchment area. While the city manages extensive drainage infrastructure, local officials acknowledge that the council alone cannot meet the investment required to tackle major flooding and update ageing systems.

This challenge is part of a wider regional issue, as coastal communities across the state are grappling with similar problems, including coastal erosion and the need for long-term management options for structures like seawalls and dunes.

What we don't know yet

  • Will the flood study conducted by the Department of Energy lead to specific, funded mitigation infrastructure designs?
  • What specific investment will the city require to update its stormwater network to meet future flood risks?

What would change this answer

The Department of Energy secures additional funding for large-scale mitigation projectsThe risk of severe inundation for the city's infrastructure would decrease, potentially reducing long-term financial exposure.
The levee is found to be structurally compromised beyond repair during the studyThe city would face immediate and strong pressure to implement costly emergency flood defenses.
