The Mayor of Young says he is daunted by cost of suggested works a consultant has come up with to help flood proof the town.
A draft flood study has been completed and is on public display, looking at the Burrangong Creek catchment and Young's stormwater drainage system.
Councillor Stuart Freudenstein says due to Young's hilly terrain run-off from heavy rain gets funnelled into the town.
He says the study's authors have suggested building a series of retention basins and pipelines to move the water into the creek system.
"It's going to be extremely expensive and quite daunting actually for the years ahead," he said.
"But we have to do it, because we certainly don't want those events to happen like they did at the end of 2010 when water went through some of the shopping areas.
"It's happened a few times and we certainly want it to prevent those happening again as soon as possible."
Councillor Freudenstein is urging local residents to read and make submissions on the plan.
He says there are a lot of recommendations for council to consider.
"You know, laying new pipes through existing streets, major intersections, roundabouts and down through the CBD," he said.
"It's going to be quite a complicated and involved process.
"Measures like that, and retention basins up in the catchment area, up on the slopes, leading into town.
"That'll certainly be another measure looked at as well."
