The Rockhampton council has launched a campaign aiming to convince sceptical residents to back its Fitzroy River flood levee proposal.
The council has released a $1.2 million study on a levee that would protect the city's southside from flooding by pushing excess water over the Yeppen flood plain.
Hydrology experts and engineers will consult residents at an open day tomorrow at the Quay Street parklands at Depot Hill.
Jim Niehoff from engineering firm Aecom says the levee protects about 1,000 blocks of land.
"Any excess water will run over the top of the levee in that specific section and then slowly fill up the inside so that it balances out with the outside," he said.
"The levee system is designed for a 100-year storm. If we get a 110-year storm it frankly will not hold that water back, so we built in a specific location where that overtopping can occur and it's in a rural area."
