Low lying parts of Ipswich CBD downstream of Limestone Park are now better protected from flash flooding after localised heavy rainfall with the completion of a new detention basin adjacent to the helipad.
Ipswich City Council CEO David Farmer said the site within the park was also bordered by the skate park and PCYC.
“A detention basin is designed to store stormwater runoff for a limited time and then release it slowly over several hours through a small outflow at the lowest point,” he said.
“The new Limestone Park detention basin was constructed at a cost of $2.1 million.
“It will have significant benefits during flash flooding, however it will not prevent a major river flood such as occurred in 2011 and 1974.
“Ipswich has a number of existing detention basins across the city including major basins at Marburg, Rosewood and Redbank Plains.”
Part of the Limestone Park project also included a new irrigated cricket pitch.
