Keeping our communities safe

Significant flood events, like those in Brisbane in 2011 and those more recently in NSW show the importance of managing flood risk up to and beyond the 1% annual exceedance probability (AEP) flood and considering flood risks up to the probable maximum flood level. This will build resilience in communities located on floodplains and reduce the extent of property damage and potential loss of life from severe to extreme flooding throughout NSW.


The Department of Planning, Industry and Environment works closely with our colleagues in the Environment and Heritage division, who manage and monitor our wetlands, rivers, floodplains, coasts and estuaries, as well as other agencies such as Resilience NSW, the NSW State Emergency Service who are the lead combat agency for flood, storm and tsunami events; and Infrastructure NSW who lead the implementation of the Hawkesbury-Nepean Flood Risk Management Strategy.


Updated guidance for councils

The finalised flood-prone land package commenced on 14 July 2021.

The package provides advice to councils on considering flooding in land-use planning and includes:

To accompany the finalised package, a submission’s report is also available. The report summarises feedback received during exhibition and how that feedback was addressed in the final documents.

The updated guidance:

  • supports better management of flood risk beyond the 1% annual exceedance probability,
  • ensures best management practices in managing and mitigating severe to extreme flood events, and
  • builds greater resilience into communities in floodplains and reduce potential property damage and loss of life in recognition of increasing extreme flood events throughout NSW.

Councils expression of interest

The department has asked councils to submit their interest to incorporate the optional standard instrument ‘special flood considerations’ clause to apply to their LEP.

Following the expression of interest, we will undertake targeted engagement with relevant councils and develop an appropriate review mechanism, seeking external views, to assist both a council and the department in evaluating whether the adoption of the clause in the local environmental plan is appropriate.
