Rockhampton's Mayor says she is not sure how much of the Lakes Creek Road area will be protected by a flood mitigation program on the city's northside.
This year's budget contains about $100,000 for the first stage of a $500,000 long-term project to install flood valves to close off stormwater drains, turning the rail line into a virtual flood levee.
Margaret Strelow says it will take up to five years to finish the work but she is unsure how far they will be able to extend.
"There's a point at which it will become more expensive and it may not be possible to go the whole length down but the sorts of streets that we're used to flooding and [have] seen consistent flooding, Nobbs Street and Berserker Street, those are the streets that will see the benefit," she said.
"We're scheduling probably four or five years but the beauty of this is that every valve has a positive impact, so even if we've only got two done by the time the next flood comes, there will be some properties that will get a benefit.
"It's a little bitty difference I guess for the South Rocky flood levee which is, you can't build half a one of those and get any benefit."
