Climate change in Casey

Global warming and climate change poses a significant challenge to all of us.

We're working with other councils in the region through the South East Councils Climate Change Alliance (SECCA) to understand the major impacts of climate change and global warming, and how we can prepare for them.

Rainfall and drought

Casey, like most of south-east Australia, is expected to experience much lower amounts of average rainfall. The CSIRO predict rainfall will decrease by 8% in 2030 and 23% by 2070.

Potential impacts

  • Increased drought frequency and severity.
  • Increased water prices.
  • Drying of wetlands, creeks and other water bodies.

How we're addressing them

  • Installing drought-tolerant turf types on playing fields and centralised irrigation systems for more efficient water use.
  • Including rainwater tanks in many of our building refurbishment works, sports pavilions and club rooms.
  • Planting drought and heat tolerant landscapes in public open space.

Storms and floods

Although there will be less average rainfall, when it does rain storm events are likely to be more extreme. Increased rainfall intensity may cause flash flooding and the strength and frequency of wind is also expected to increase.

Potential impacts

  • Increased risk of flooding in 3,800 residential and 210 industrial and commercial properties in Casey.
  • Increased impact on public infrastructure including schools, buildings, roads, drains and sewers.
  • Reduced agricultural production.

How we're addressing them

  • Creating artificial wetlands to 'filter' stormwater/floodwater.
  • Sealing roads to minimise environmental effects including erosion, and gravel and sediment run-off.
  • Developing a long-term vision to protect foreshore reserves, environmental, heritage and recreational values.

Fire risk weather

Casey is expected to be hotter and drier. This is due to the combination of higher temperatures, increased evaporation, and the reduction in annual rainfall. The drier landscape will result in an increased risk of bushfires.

Potential impacts

  • Increased demand for emergency response, medical assistance and recovery.
  • Impacts on public facilities including schools, reserves and parks.
  • Health impacts from decreased air quality.

How we're addressing them

  • Annual fire prevention inspection program.
  • Increased funding for fire prevention works.
  • Implementation of the Municipal Fire Management Plan and the Fire Management Communications Plan.

Extreme temperature

Average temperatures are expected to increase, as is the number of extreme heat days and heat waves. The average annual temperature is predicted to increase by up to 1.3 degrees in 2030 and up to 3.5 degrees in 2070.

Potential impacts

  • Increased number of power outages in summer.
  • Increased energy costs.
  • Increased vulnerability from heat stress, particularly among infants and the elderly.

How we're addressing them

  • Developing procedures to identify and support isolated elderly residents.
  • Annual assessments of sporting ground surfaces to limit potential for injury resulting from drought.
  • Using appropriate construction materials when building roads, paths and other infrastructure.

Rising sea levels

Sea levels have already risen and this is projected to continue. The effects of sea level rise will be most pronounced during extreme tides and storm events when the effects of wind amplify the height and force of waves. Sea levels are predicted to rise up to 490mm in 2070.

Potential impacts

  • Flooding in low-lying residential and commercial properties.
  • Damage or loss of beaches, coastal wetlands and foreshore reserves and their amenities.
  • Impacts on businesses dependent on beach-related tourism.

How we're addressing them

  • Long-term planning for safe boating and harbours.
  • Renewing zoning and development laws regarding coastal areas.
  • Working with the state government's Future Coasts project to increase our understanding of how climate change will impact on the coastline around Western Port.
