Flood and drainage studies
Access raw data from various council projects, such as flood or drainage studies.
The following flood and master drainage studies are the basis of published flood mapping products.
In addition, council has prepared flood models to determine overland flow paths for the following locations. The outputs of these models also contribute to the public flood mapping products published by council. Reports do not exist for these models, however the modelling methodology is the same as the master drainage studies from the list above.
| Location of overland flow model | Creator |
| Bli Bli | SCC |
| Buderim – Kunda Park | SCC |
| Caloundra West | SCC |
| Eumundi | SCC |
| Golden Beach | SCC |
| Palmwoods | SCC |
| Woombye | SCC |
| Yandina | SCC |
| Yaroomba | SCC |
Mapping from these flood studies and models are available online via council’s MyMaps system and can be accessed under general information (flood mapping) in the layer list.
The mapping represents the original flood study outputs. Other council flood products for land use planning and emergency preparedness purposes have been developed from this information by determining the highest flood level at any given location. Often the flood levels of regional catchments are the dominant flood level, but this could obscure the fact that there may be a localised flooding issue associated with drainage in an area.
It is expected these flood study reports and the associated online mapping will be of most interest to consultants undertaking investigations on behalf of developers, and may be referred to by council’s own Development Services staff as part of the development application process.
Provide feedback: Council is currently seeking feedback on how easy this flood mapping and information is to navigate and understand. Please view the factsheets, FAQs and how-to videos to help you explore the mapping.
General information mapping layers
Council’s emergency preparedness and land use planning flood mapping products are created using information from numerous flood study and master drainage study reports.
Council’s general information mapping layers contain data from the flood studies, master drainage studies and overland flow path models listed above.
The general information mapping layers present flood extent and flood hazard mapping for a range of flood likelihoods.
These layers are often used by council’s own development services team. The mapping offers original raw data from various studies which can help to inform other projects. In some locations these mapping layers are likely to assist with a better understanding of drainage and overland flow in locations that are also affected by regional flooding.
