Wollongong City Council has reviewed and updated the Wollongong City Flood Study.
The catchment area incorporates southern Wollongong, Wollongong City, parts of Mangerton and down to Tom Thumb Lagoon.
Council's initial flood study for the catchment was completed in April 2013.
This was followed by a Flood Risk Management Study and Plan in 2015, which contained a list of actions that they have been progressively completing.
This latest review is taking place because council is taking into consideration changes to the catchment and modelling guidelines.
Council received hundreds of community submissions about the flooding and drainage problems they'd experienced on their properties.
Council's manager of infrastructure, strategy and planning Mike Dowd said the flood study that was now on public exhibition hadn't changed much from the previous study.
"More detailed analysis has found that flood levels have increased very slightly in the lower catchments down towards Swan Street in that southern Wollongong area, and slightly reduced in the top end of the catchment just south of Crown Street," he said.
"We're after more information from the community about what's happening in their space.
"If you were flood-affected in the previous study, you are still probably going to be flood-affected in this study. If you weren't, it's a very high likelihood that you're not going to be in this study."
Mr Dowd believed the vast majority of community members "know that there isn't anything that a council or a landowner can do to prevent a flood".
"What we can do is understand that flood as best we can, and put in place actions to minimise the impact of that flood," he said.
The updated study explains the ways flooding happens in the Wollongong City catchment.
The study considers recent urban developments, changes to the Gurungaty waterway and information collected after recent flood events.
The community can have their say until June 18.
Council will host community information sessions:
*Thursday, May 30 - 4pm to 6pm at BlueScope Gallery, Level 3, Wollongong Art Gallery, 46 Burelli Street, Wollongong.
*Saturday, June 1 - 10am to 12pm at JJ Kelly Park (near the playground), corner of Swan and Keira streets, Wollongong.
Residents can also complete an online feedback form on council's website.
