Floodplain Management

Floodplain Studies and Plans for Bogan Gate / Gunningbland and Cookamidgera have been adopted. 

Gunningbland and Bogan Gate properties are routinely affected by flooding, extreme events have caused significant land and property damage and required emergency accommodation and SES operations to house displaced residents and provide support for those isolated. A flood study and floodplain risk management study were being delivered for the Gunningbland Creek catchment area and Bogan Gate township to quantify the risk and determine options that may be implemented to reduce the impact of flood water on those communities. It has included assessment of the Sydney to Perth trunk railway line and parallel State Rail to determine the impact of these on flood characteristics and mitigation measures to reduce flood afflux due to these structures. It has also identified "dry areas" for use during flood events and inform SES planning for managing isolated properties during flood events. The additional collection, review and follow up on information from the community post November 2022 flood event, and update of the calibration / validation of flood modelling so there is a match between the observed flooding and modelled flooding.

Cookamidgera properties are routinely affected by flooding, extreme events have caused significant land and property damage and required emergency accommodation and SES operations to house displaced residents and provide support for those isolated. A flood study and floodplain risk management study has been delivered for the Cookamidgera catchment area and Cookamidgera township to quantify the risk and determine options that may be implemented to reduce the impact of flood water on those communities. This will include assessment of the Sydney to Perth trunk railway line and parallel local road network to determine the impact of these on flood characteristics and mitigation measures to reduce flood afflux due to these structures. It will also identify "dry areas" for use during flood events and inform SES planning for managing isolated properties during flood events.
