What is a floodplain? A floodplain is an area of land that has been formed by flooding over time and is still subject to periodic inundation. Floodplains are also referred to as flood prone land. Gosford has many types of waterways and water bodies ranging from lagoons, creeks, rivers, dams, overland flow paths, tributaries and estuaries. These are surrounded by steep catchments that produce fast flowing water in periods of heavy rain. This stormwater is collected and contained by these waterways. However, in periods of extensive or heavy rainfall, the waterways cannot contain all the stormwater and it therefore spills out onto the adjoining land – known as a floodplain. Floodplains or flood prone land includes all land affected by flooding up to and including the Probable Maximum Flood (PMF) event (or the highest conceivable flood that nature can produce). Only land that is above these levels is truly flood free.
What is the floodplain risk management process? For more detailed information regarding the Floodplain Risk Management Process, please refer to the NSW Floodplain Development Manual 2005. Floodplain Risk Planning Fact Sheet
