Sioux City is currently using an automated parking citation-issuance system, which consists of portable handheld computers in conjunction with host software installed on a PC system. Hours of enforcement are Monday through Friday from 8 a.m. to 6 p.m.
After 30 days, the fine cost increases to $14 and $35.
