About Alexandra Hills's Climate Risk Profile

Alexandra Hills, located in the Redland City Council area, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to waterways and bushland elevates its risk profile, particularly concerning flooding and bushfires.

Rising temperatures and more frequent heatwaves pose a significant threat to public health, especially for vulnerable populations. The urban environment exacerbates the heat island effect, leading to higher nighttime temperatures and increased energy demand for cooling.

Coastal risks, including sea level rise and storm surge, also present a challenge for Alexandra Hills. Low-lying areas are susceptible to inundation, potentially impacting property values and infrastructure.

Addressing these climate risks requires a multi-faceted approach, including investments in stormwater infrastructure, bushfire mitigation strategies, and community awareness programs. Residents should take proactive steps to protect their homes and prepare for extreme weather events.
