Consultation has concluded

Comments on the draft Dora Creek Flood Study, Floodplain Risk Management Study and Floodplain Risk Management Plan have now closed.

Over the coming weeks, Council officers will review the submissions received for the Dora Creek Flood Study, Floodplain Risk Management Study and Floodplain Risk Management Plan. Once feedback has been collated, a report which will include any appropriate amendments to the flood risk management options, is expected to be presented to councillors next year.

These documents define the nature of flood risk in the area and provide management recommendations for more effective flood planning. This assessment updates the previous 1986 Dora Creek Flood Study.

The floodplain risk management study builds on the flood study to identify a number of measures, which can be used to reduce flood risks in the catchment in the future such as:

  • setting appropriate levels for development control;
  • identifying works to reduce flooding; and
  • raising community awareness of flooding issues so that they can take necessary precautions.

The floodplain risk management plan identifies which of the options considered in the risk management study are recommended for adoption by Council.

It is important for the community to be involved in these studies and be aware of the planning required to protect assets and people in their area.

    almost 6 years ago
    • The largest flood event recorded in Dora Creek occurred on March 1977, followed by the June 2007 long weekend, however larger events are possible
    • Blockages within culverts and bridges have the potential to significantly impact the functioning and capacity of Dora Creek during flood events
    • Up to 154 buildings are expected to be affected by over-floor flooding in a 1-in-100 year flood. This is 37 fewer buildings than were identified as affected in the previous (1986) Dora Creek Flood Study
    • Most of these properties are on Dora Street, while a smaller proportion of affected properties are in Stingaree Point Drive...

    • Most of these properties are on Dora Street, while a smaller proportion of affected properties are in Stingaree Point Drive and Cowell Street
    • Flood modification options that have been considered to reduce the impact of flooding on properties include onsite detention, levees and floodways
    • Property modification options such as development controls have been suggested to manage flood risk
    • Flood response options suggested include an improved early warning system and education to raise awareness of flooding and encourage residents and visitors to prepare for flood emergencies.
