Hazard Breakdown

Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.

Climate Hazard Breakdown for Sun Valley

Flood

Sun Valley faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from local waterways. The risk is exacerbated by the suburb's topography and existing drainage infrastructure.

Key drivers:

  • ·Increased rainfall intensity
  • ·Urban development

Bushfire

Sun Valley has a high bushfire risk due to its proximity to bushland and prevailing weather conditions. Hot, dry summers and strong winds increase the likelihood of bushfires impacting the area.

Key drivers:

  • ·Climate change
  • ·Fuel load

Heat

Sun Valley experiences a moderate risk from heatwaves, with increasing average temperatures and more frequent extreme heat events. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk.

Key drivers:

  • ·Climate change
  • ·Urban heat island effect

Coastal

Sun Valley has a very low risk from coastal hazards due to its inland location. Sea-level rise and coastal erosion are not significant threats to the suburb.

Key drivers:

  • ·Distance from coast
  • ·Elevation

What This Means for Property Owners

Insurance Outlook

Insurance premiums are likely to increase due to the elevated risk of bushfires and flooding.

Price Impact

Properties in high-risk areas may experience a decrease in value.

Buyer Checklist

  • 1.Check flood maps and bushfire prone areas.
  • 2.Assess property's vulnerability to extreme heat.
  • 3.Review insurance options and costs.
  • 4.Consider long-term climate risks when making a purchase.

How the region's climate is projected to change

Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.

Temperature

+0.5 to 1.1°C by 2030

Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.

Rainfall

Winter rain down up to 15% by 2030

The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.

Fire weather

Harsher, magnitude uncertain

High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.

Sea level

+0.12 m by 2030

At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

About Sun Valley's Climate Risk Profile

Sun Valley is a suburb in New South Wales that is increasingly vulnerable to the impacts of climate change. The primary risks include bushfires, flooding, and heatwaves. These hazards pose a threat to property, infrastructure, and human health.

The risk of bushfires is elevated due to the suburb's proximity to bushland and the increasing frequency of hot, dry conditions. Climate change is contributing to longer fire seasons and more intense fires, making it crucial for residents to implement bushfire preparedness measures.

Flooding is another significant concern, with heavy rainfall events capable of causing flash flooding and riverine flooding. Inadequate drainage infrastructure and urban development can worsen the impacts of flooding. Residents should be aware of flood risks and have a plan in place.

Heatwaves are becoming more frequent and intense, posing a particular risk to vulnerable populations. Rising temperatures can lead to heat stress, dehydration, and other health problems. It is important to stay cool and hydrated during heatwaves.

Addressing these climate risks requires a combination of mitigation and adaptation measures. Mitigation involves reducing greenhouse gas emissions to slow down climate change. Adaptation involves taking steps to protect communities from the impacts of climate change.

Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
