Rural floodplain management plans

Key rural floodplain management plan outcomes

Rural floodplain management plans under Part 8 of the Water Act 1912 (to be replaced by provisions within the Water Management Act 2000) are developed to achieve the following key outcomes:

  • mapping of floodplain development, major flood flow-paths and flood dependent ecosystems to better manage floodplain assets
  • mapping of unobstructed floodway networks to allow effective passage of floodwaters and maintain floodplain connectivity to protect and enhance flood dependent ecosystems and fish passage
  • provision of guidelines to determine where landholder flood protection works can and cannot be constructed
  • provision of remedial solutions to resolve hydraulic and environmental 'hot-spots' using a strategic and risk management approach
  • provision of assessment criteria for regulating existing and future flood control works within floodway networks.

These outcomes are designed to benefit rural communities and the floodplain environment allowing farmers to plan for future sustainable development based on a strategic scheme for the management of floodwaters.

Development of rural floodplain management plans

The Office of Environment and Heritage prepares rural floodplain management plans which are made statutory plans under Part 8 of the Water Act 1912 which is administered by the NSW Office of Water.

NSW Office of Water is responsible for assessing and approving flood control works associated with agricultural pursuits (earthworks, channels, embankments or levees) which can affect the distribution of floodwaters within designated floodplains. Rural plans form the basis of assessing flood control work approvals.

It is proposed to progressively develop rural floodplain management plans for each of the State's key inland floodplains. The Natural Heritage Trust, Natural Disaster Management Program (NDMP) and the State Assisted Floodplain Management Program have all provided funding for the preparation of rural plans.
