Flood

45/100

Darlington faces a moderate risk of flooding, primarily from heavy rainfall events and potential stormwater runoff. The risk is expected to increase due to climate change.

Key drivers:

·Increased rainfall intensity
·Urbanisation

stable

Bushfire

20/100

Darlington has a low bushfire risk due to its highly urbanised environment and distance from significant bushland areas. However, ember attack from distant fires remains a potential concern.

Key drivers:

·Urban density
·Limited vegetation

increasing

Heat

60/100

Darlington experiences a high heat risk, particularly during summer heatwaves. The urban heat island effect exacerbates the risk, leading to higher temperatures compared to surrounding areas. This risk is projected to increase significantly.

Key drivers:

·Urban heat island effect
·Increased frequency of heatwaves

stable

Coastal

10/100

Darlington has a very low coastal risk due to its distance from the coastline and elevation. Sea level rise is not expected to directly impact the suburb.

Key drivers:

·Distance from coast
·Elevation

About Darlington's Climate Risk Profile

Darlington, located close to the Sydney CBD, faces a number of climate-related challenges. The suburb's urban environment contributes to the urban heat island effect, making it particularly vulnerable to heatwaves. Climate change projections indicate a significant increase in the frequency and intensity of heat events, posing risks to vulnerable populations.

Flooding is another concern, with potential for stormwater runoff and heavy rainfall events to cause localised flooding. While the suburb is not directly exposed to coastal hazards, changes in rainfall patterns could exacerbate flood risks.

Bushfire risk is relatively low due to the suburb's urban density and limited vegetation. However, residents should remain vigilant during periods of high fire danger, as ember attack can occur even in urban areas.

Addressing these climate risks requires a multi-faceted approach, including urban greening initiatives to mitigate the urban heat island effect, improved stormwater management to reduce flood risk, and community awareness programs to prepare residents for extreme weather events. Adaptation measures are crucial to ensure the long-term resilience of Darlington.
