A $19 MILLION plan to raise the Granville Bridge southern approaches and buy a new portable levee to protect Maryborough's central business district will be put to the State Government.
The Fraser Coast Regional Council will lodge its application for Queensland Government funding by May 12.
Mayor Gerard O'Connell said a second option would be presented which included $6 million to raise Adelaide St and a new portable flood barrier system.
He said the council considered an option for a $15 million flood levee in Queens Park but discarded it because ensuring Granville residents were not isolated during floods, which happened an average of once every four years, was a higher priority and there were other viable options to increase flood immunity within the CBD.
"Upgrading the southern approaches to the Granville Bridge would ensure access to Granville until the bridge is flooded," he said.
"At present the bridge is trafficable until floodwaters reach 8.2m but the approach roads are cut when the flood waters reach 5.7m," he said.
"The proposal includes a 120m bridge-type structure and about 300m of approach road and embankment works to link Tiger St and Alice St.
"The proposal also extends the height of the portable flood levee used in Adelaide St from 1.2m to 1.8m and a permanent pump installed to control stormwater run-off from the CBD.
"While the current portable levee protects the CBD up to 10m floods, the new system would protect the CBD from floods up to 11.4m."
Cr O'Connell said priority two included $6 million to raise Adelaide St by 300mm and purchase a new portable levee of 1.8m to use in Adelaide St and installing a permanent pump station to control stormwater run-off .
He said the proposal would provide increased immunity until floodwaters reached 11.4m.
City and town centre development portfolio councillor Daniel Sanderson said the plans were an excellent step forward because a prepared community was a safe and resilient community.
"This will assist not only business, but the wider community and provide a confidence boost for the CBD and the Granville community," he said.
Cr O'Connell said the council had also joined with the Bundaberg Regional Council for a proposal to undertake flood modelling of the Cherwell and Burrum Rivers.
"Bundaberg is the lead agency for that funding application," he said.
"The study will provide flooding information to be incorporated into council's planning scheme and for disaster management purposes."
