Floodplain Management Program


The Floodplain Management Program is a continuing Department of Environment, Climate Change and Water (DECCW) program which responds to the severe emotional and economic losses individuals and communities can suffer as the result of floods.

Local councils have lead responsibility for managing flood prone areas, but DECCW plays a key role by helping these councils manage flood threats faced by their residents.

The State Government assists local council by providing financial support under this program, the direction provided by the Floodplain Development Manual and the standard floodplain risk management documents. 

In addition DECCW provides technical support for the development and implementation of floodplain risk management plans by local government to enable them to manage flood risk in their communities. We provide advice and support to local government on policy, modelling, management options, planning and environmental considerations, and support local councils in their bid to involve and education the community about flood risk. Our staff have a high degree of technical skills in a number of valuable areas such as engineering and land use planning and have a wide range of practical experience in floodplain risk management.

In the last 10 years alone the organisation has provided over $100M in funding for floodplain risk management projects. This has resulted in around $200M investment to numerous floodplain risk management projects across the State. In general two–thirds of this funding comes from the State Government (the Commonwealth may provide one-third for some projects), with local council providing the remaining one–third.

Councils use this funding to undertake projects to understand flood risk, assess how it can best be managed, and to implement projects to reduce the flood threat to the community.

Projects funded include:

  • Flood investigations to understand flood behaviour and assess options to both develop flood prone land and mitigate flood risk to existing development. Figure 1 shows the spread of current plan preparation projects across the State; and
  • Works projects such as the building of levees and detention basins, voluntary purchase and/or raising of houses in areas at high flood risk. Figure 2 shows the spread of current plan implementation projects across the State.
