Flood inquiry hears criticism of terminology

ELEANOR HALL: The Queensland Floods Inquiry has heard calls for a freeze on the development in one of Brisbane’s riverside suburbs.

Brisbane’s industrial areas are being gentrified with luxury apartment buildings. But a flood victim today described chaos during this year’s flood evacuation and criticised the council’s plans to allow up to 80,000 more residents and workers into the area.

The inquiry also heard from more witnesses concerned that the official flood terminology is misleading.

Annie Guest is at the inquiry and joins us now.

ELEANOR HALL: Annie tell us first about these concerns about the flood terminology?

ANNIE GUEST: Well this Q100 flood terminology, it’s a figure that’s used in government, by government, council and insurers and a figure that a lot of residents look to as a guide for their property’s flood risk.

Now, what it is, a one in 100 year flood is calculated to be the level of water expected to be equalled or exceeded every 100 years on average. But what that actually means is that there’s a 1 per cent chance each year of a major flood reaching a designated level.

However, it has become clear that this is anything but clear and many people have felt that the figure meant their property was only at risk of such a flood once in every 100 years.

ELEANOR HALL: So what are witnesses telling the inquiry about the terminology?

ANNIE GUEST: Well this morning a 79-year-old retired mathematician gave evidence, a former university lecturer. Now his retirement village was forced to evacuate as the flood came into his inner Brisbane suburb. They had to flee with only their medication.

He told the inquiry his fellow residents didn’t and still don’t understand the Q100 figure and he only understood it because he says he researched it. He said there’s also terminology such as the one in 2,000 year event. He says it’s just bamboozling. There’s no data for this as records only go back 150 years and he called on the inquiry to make a comment on this.

And the commissioner Cate Holmes thanked him as he left after his contribution.

ELEANOR HALL: Now the commission’s also been hearing about the redevelopment of inner Brisbane. What did it hear today?

ANNIE GUEST: Heard from a resident, Paul Rees of West End, an inner Riverside suburb. He says that there’s a plan there for an extra 25,000 residents and up to 55,000 workers but he described chaos in the evacuation as the flood came in, in January, and it inundated the ground floor, the basement of his building, which was the first luxury apartment building in that former industrial area.

Now he said I can’t see how so many more people would even get out during a disaster and he wants a freeze on development while this is considered.

ELEANOR HALL: Annie Guest at the inquiry, the Queensland Floods Inquiry, in Brisbane thank you.
