Beik said construction of a reservoir in Tipton County would cost about $66 million.
Board member Ken Hedge said until a study is done the drainage board won’t know the benefits and impacts.
Bert Weaver, a board member, said the board wants to do the project right and not continually do patch work that doesn’t resolve the problem.
In 2009, the Big Cicero Creek board proposed a $2.7-million plan to bench, or widen, the creek to hold more water and a gradually release it downstream. That proposal died when local residents weren’t willing to pay the cost.
Beik said in May the board has three options: Do nothing, a smaller project like benching, or the larger bypass project.
“Either option will send water more rapidly downstream,” he said. “Is that tolerable in Hamilton County?”
Beik said a bypass will address 95 percent of the problems during a 100-year flood as compared to 40 percent of the flooding issue if the benching project moves forward.
