081319 432 Sioux City Council members asked the city attorney yesterday to rework a proposed noise ordinance after local bar owners said it would hurt their businesses.

At its last regular meeting, the council voted 3-1 to move forward the ordinance, which would require organizers to scale back the length of outdoor events generating noise
