The Warrumbungle Shire Council says building a levee, to protect 40 homes at Baradine from flooding, is at least four years away.
The council has considered several options including buying land on the floodplain and moving houses to higher ground, but that is considered to be too expensive.
The director of technical services Kevin Tighe says it will take three years to carry out an investigation and designs for a levee and even longer before the work is completed.
He says Baradine residents have been waiting for this for some time.
"Baradine people are inundated with flood flows on average once every two to three years.
"It's a floodplain that rises quickly and often doesn't give people enough time to react so we're looking to have in place a levee that will protect people from flooding."
He says the council has received more than $380 000 to design the levee and is considering two options.
"The survey investigation design will involve looking at a full levee for the town and a levee that involves diverting some of the water, some of the flood flows to another system.
"So the design will look at both options for the levee."
