There are calls for a levee system to be built around Brisbane's CBD to increase the Australian city's resilience to major events like flooding.
Design and consultancy firm Arcadis released its City Resiliency: More than just a disaster report today.
It said Brisbane risked falling further behind other domestic and global cities unless it addressed three key issues, one of which was major flooding and stormwater surges.
The report called for a levee to be built around the CBD, from Boundary St to the Eagle Street dining precinct.
Arcadis' southeast Queensland city executive Louisa Carter said Brisbane could not become an economic capital until it confronted "some simple truths".
