The March 2021 flood in the Hawkesbury-Nepean was the largest flood in the region since August 1990. It has been classified as a moderate to major flood, peaking at 12.9 metres above sea level at Windsor. NSW State Emergency Service (NSW SES) led the flood response, including the issuing of evacuation warnings and orders. Infrastructure NSW was proud to support the NSW SES in their emergency response to the March 2021 flood event. This included supporting the incident management team and community liaison.
Infrastructure NSW is leading the delivery of the NSW Government’s Hawkesbury-Nepean Valley Flood Risk Management Strategy and has a dedicated directorate that includes flood risk and evacuation specialists, GIS mapping analysts, and community engagement and resilience specialists.
