Council completed the Allans Creek Floodplain Risk Management Study and Plan in August 2024 for this catchment. The study was jointly funded by Council and NSW Government, and was prepared in accordance with the NSW Government’s Flood Risk Management Manual (2023) and the Australian Rainfall and Runoff 2019 guidelines.
The study provides the most up to date information on flooding for this catchment. The study also identified flood risk across the catchment, investigated various options and recommended a range of flood mitigation measures.
The Allans Creek Floodplain Risk Management Study and Plan dated August 2024 includes updated version of the Flood Study (2019) with ARR19 guidelines. The study also supersedes the 2008 Floodplain Risk Management Study and Plan.
