Options to implement a quiet zone include four- or three-quadrant vehicle gates, medians or channelization devices, street closures, one-way streets or wayside horns.
"Generally speaking ... the quiet zone process takes about two years," Mielke said.
Little noted that Tuesday's session was simply to consider options and more discussions need to be held before any concrete decisions can be made.
"Crossing closures increase quiet zone feasibility," Mielke said. "If you look at Clay, McLean and Kitterman, do there need to be all three? If you closed one, it could save the cost of making the improvements."
Mielke said while federal and state funding don't exist for the costs associated with quiet zones, the city should consider economic development and Community Development Block Grant funds.
"It needs to be cost effective in order to be implementable," he said.
