About Brookvale's Climate Risk Profile

Brookvale, located on the Northern Beaches of Sydney, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to waterways and the coast makes it susceptible to flooding and coastal erosion. Rising sea levels and more intense rainfall events are expected to exacerbate these risks in the coming decades.

Heatwaves are also a growing concern for Brookvale residents. As average temperatures rise, the urban heat island effect will further amplify the heat, posing health risks to vulnerable populations. Bushfire risk is present due to the proximity of bushland areas, requiring ongoing vigilance and preparedness.

The Northern Beaches Council is actively working to address climate change through various strategies and initiatives. These include improving stormwater management, protecting coastal areas, and promoting sustainable practices. Residents can also take individual actions to reduce their carbon footprint and prepare for extreme weather events.

Adapting to climate change is essential for ensuring the long-term resilience of Brookvale. By understanding the risks and taking proactive measures, the community can mitigate the impacts and create a more sustainable future.
