A long-term plan to reduce flood risk in the most flood exposed region in New South Wales, the Hawkesbury-Nepean Valley.
Floods in the Hawkesbury-Nepean Valley pose a significant risk to people’s lives, livelihoods and homes because of the valley’s unique landscape and the size of its population.
In May 2017, the NSW Government released Resilient Valley, Resilient Communities – Hawkesbury-Nepean Valley Flood Risk Management Strategy (Flood Strategy) to reduce and manage this significant risk.
The Flood Strategy is the result of years of investigation into the best ways to reduce the flood risk in the Hawkesbury-Nepean Valley. It contains a mix of measures and is being delivered by the NSW Government with local councils, businesses and the community.
Infrastructure NSW is overseeing and coordinating the delivery of the range of important Flood Strategy measures. These include:
For the latest progress on the Flood Strategy, visit the latest updates page.
As a key part of the Flood Strategy, the NSW Government has prepared a new Regional Flood Study providing the most up to date information on river flooding in the Hawkesbury-Nepean Valley.
The Regional Flood Study uses the latest data available and a sound scientific approach, and has been reviewed by independent flood experts. It was completed in liaison with councils in the valley.
As the study comprises three large volumes, including 382 maps, you can contact us at firstname.lastname@example.org to request a full copy on USB, if required.
While there hasn’t been a major flood in the Hawkesbury-Nepean Valley for over 25 years, floods can and will happen again. Floods can happen in any year, and sometimes without much warning. We need to be prepared.
Nothing can stop flooding completely in the Hawkesbury-Nepean Valley. People will always need to evacuate when directed to protect lives in a flood emergency. If you live or work in the valley, know your flood risk and be prepared.
Find out more about how to prepare for a flood on the NSW State Emergency Service website.
