Council continuously works on updating and improving our understanding of flood risk within the Port Stephens area using the NSW government's Floodplain Management Program.

Floodplain Management Process:

There are 5 stages in the Floodplain Management Process:

  1. Data Collection - collecting relevant information
  2. Flood Study – build a hydraulic model to define the nature and extent of the flood problem in technical rather than map form
  3. Floodplain Risk Management Study – update the hydraulic model to determine options in consideration of risk
  4. Floodplain Risk Management Plan – planned actions to be adopted for Council
  5. Plan Implementation – doing the works.

Port Stephens flood studies and plans:

Information on the flood studies, drainage studies and floodplain risk management studies and plans that have been undertaken in the Port Stephens area can be accessed below.
