Council is exploring options for managing the impact of floods in the Johnstons Creek and Whites Creek catchment.

In 2017 Council completed the Johnstons Creek and Whites Creek Flood Study. This involved modelling flood behaviour using rainfall data and information from the community about past storm events. The study determined:

  • Where flood water will run
  • How the existing drainage system will cope
  • Which properties are affected

The results from this investigation can be found in the completed Flood Study.

Council has engaged specialist flood consultants, Stantec, to prepare a Floodplain Risk Management Study and Plan (the Management Plan) for Johnstons and Whites Creeks. This involves reviewing the Flood Study and identifying options for reducing flood risk in the catchment.

The primary objective of the flood Management Plan is to identify options to mitigate and manage flood risk. This will involve consideration of options that seek to:

  • Modify flood behaviour (e.g. levees, upgrade of stormwater systems)
  • Mitigate the impact of flooding on existing properties (e.g. via floor raising)
  • Control future development in the floodplain
  • Guide emergency management when a flood occurs

Future development on properties that are flood affected may be subject to development controls.

We asked the community to share their recent experiences of flooding in the Johnstons/Whites Creeks catchment to ensure the flood management plan reflects current areas of concern.

Community members could also let us know their preferences for flood management options in the catchment area.

The project team will use your feedback and other information to develop the final flood Management Plan. Everyone who provides feedback will be updated via email and on this project page.
