Herbert River Flood Mapping Update 2015
In 2003 WBM Oceanics Australia completed the Herbert River Flood Study for the Herbert River Improvement Trust. A deliverable of this study was the production of flood level, depth and hazard mapping. Since the completion of this study more data has become available to improve the accuracy of the model. In December 2015, BMT WBM in association with Venant Solutions Pty Ltd undertook an update to Council’s Flood Model. These updates have resulted in changes to the flood level, depth and hazard predicted by the model. These updates are not reflected in the mapping referred to in the current planning scheme, but have formed the basis for the new planning scheme which is currently being produced. The updated model is now being used to issue 100 Year Flood Level Certificates.
Council has recieved numerous enquiries from the general public regarding the lack of flood information available through Council. These requests have prompted the development of a full set of flood maps for both the flood hazard and flood depth for the 5, 10, 20, 50, 100, 500 and possible maximum flood events. A total of 70 maps have been developed, which cover the following areas of the Hinchinbrook Flood Plain:
- South Ingham (Toobanna and Blackrock)
- Lower Herbert Area (Bemerside, Macknade and Cordelia)
The 2015 Herbert River Flood Depth and Hazard Maps have been released for public consultation as part of the 2017 Draft Hinchinbrook Shire Planning Scheme communication and consultation strategy.
Note that the beach communities of Taylors Beach, Lucinda and Forrest Beach fall under the storm surge model, which is not included in this study.
