The Hawkesbury-Nepean Valley is one of the most complex floodplains in Australia. Not only does it contain a unique landscape, it’s home to some of the fastest growing areas of Western Sydney, as well as some of the earliest areas of European settlement in Australia.
The government’s Resilient Valley, Resilient Communities: the Hawkesbury-Nepean Valley Flood Risk Management Strategy identifies the risk and challenges in the 425 square kilometres of Hawkesbury-Nepean Valley floodplain. Historic decisions about the location of settlements and villages within the floodplain coupled with the need to plan for the sustainable future of its residents means there is a greater need for risk-based land use planning to prepare for flood events. This will ensure development is located outside of the high-risk areas, that the built form is resilient and development considers evacuation needs. The strategy is a long-term plan for the NSW Government, councils, businesses and the community to work together to understand and manage the flood risk as well as preparing for flood events.
Risk-based land use planning will be used to support community resilience as part of a broader range of measures.
