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, Energy and Science 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.
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:
For further information about the changes:
We are asking councils to submit their interest to incorporate the optional standard instrument ‘special flood considerations’ clause to apply to their LEP.
This expression of interest will enable the department to undertake targeted engagement with relevant councils and does not commit councils to the 5.22 ‘special flood considerations’ clause.
We will contact all councils that submit their expression of interest. We will also 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.
Submit your interest by 30 July 2021 if you wish to opt in.
If you have any queries, you can contact a Specialist Planning Officer - Floodplain Management at firstname.lastname@example.org.
