(Beaver Dam) Overnight on-street parking in Beaver Dam is now prohibited until spring. Mayor Becky Glewen announced Saturday that winter parking rules are now in effect. No parking is allowed on city streets between 2am and 6am, so that the Department of Public Works can clear snow. Citations will be issued for violations and begin at $20 if the ticket is paid within five days. The parking ban will remain in effect until April 1 unless it is announced that the ban has been temporarily or permanently lifted. A $40 on-street parking permit is required for those who have no alternative but to park on the street. Permits can be picked up at the city finance office during regular business hours.
