ROCKLAND — The Rockland City Council gave unanimous preliminary approval Wednesday night to revamping the city’s overnight winter parking ban.

Instead of automatically prohibiting overnight parking on public streets from Dec. 1 through March 31, the city will announce emergency parking bans on a case-by-case basis in the event of winter storms. The city has had the current winter nighttime parking ban for at least 40 years.

The change was proposed by Councilor Louise MacLellan-Ruf. The vote was taken Oct. 13.

Under the proposed new ordinance, the emergency parking ban would go into effect at 10 p.m. and continue through 6 a.m. to allow municipal public service crews to clear streets. Under extreme circumstances, the length of the emergency ban could be extended.

City Manager Tom Luttrell said the city is looking into a software package where people can sign up to receive notices when the bans are imposed. The media will also be notified to inform the public.

A formal public hearing and final vote are scheduled for Nov. 8. If approved, the new law would take effect Dec. 8.
