Brisbane’s lord mayor says new homes will inevitably be built in flood-prone parts of the city.

Brisbane’s lord mayor says it’s inevitable new homes will be built in parts of the city that are known to flood.

Graham Quirk says the entire city is built on a flood plain, and banning development in areas that go under will deny people their property rights.

He made the comments as the Brisbane City Council debated a plan to manage growth in the city over the next 20 years.

“The proposition has been put forward somehow we ought not be allowing development on land that does flood. The reality is this city is built on a flood plain,” he said, according to Fairfax media.

“We need to make the provisions available and assess applications based on building flood immunity in relation to development.

“But it does not mean if a piece of land has flooded at some point in this city’s history that no development should occur on that site. That would mean the denying of people’s property rights.”

Mr Quirk said significant flood mitigation works had been carried out since the 2011 floods.

The inquiry into the 2011 floods disaster made a series of recommendations about how councils should handle development in areas at risk of flooding.

They included a recommendation for councils to create “limited development” zones in their planning schemes for areas considered to be at high risk of flooding.

It also said councils should consider, among other things, how development on flood plains could affect the flow of water during flood events.

The Insurance Council of Australia (ICA) says residential development in flood-prone areas of Brisbane is only feasible if robust development controls are used.

An ICA spokeswoman said development should only be considered if the type of building, its location and construction materials were appropriate for a flood zone.

Insurers considered the effectiveness of flood mitigation, combined with development controls and material selections when calculating insurance premiums, she said.
