IPSWICH residents can now obtain detailed information on just how their property was affected by the January flood.
Council Planning and Development Committee chairman Paul Tully said the updated maps reflected the most accurate recording of flood levels in the history of the city.
"All property owners in Ipswich can now access this free service online," Cr Tully said.
"In what we believe to be a Queensland first, Ipswich City Council has introduced a comprehensive package which includes an easy to read description of the property, the height of both the 1974 and 2011 floods measured against the highest and lowest points on the property and the building eave height."
Cr Tully said enhancements to the service allowed access to a property's flood history and gave people the tools to make informed decisions about buying, renting, building or renovating.
"The maps are available in colour to easily distinguish between 1974 and 2011 flood levels," he said.
"Residents are also urged to go online and check flood levels well before any threat of flooding."
Cr Tully said officers has made exhaustive surveys of flooded areas immediately after the flood and used a number of sources which included aerial surveys and conducted interviews with hundreds of residents.
"We are also encouraging feedback from residents to help us further refine the information so it can be as accurate as possible."
The Council's web site host is currently completing upgrades to their systems which will boost capacity to around 600 hits per second and offer improved download speeds.
