Can I park on the street overnight?
Parking a motor vehicle or trailer overnight, within the right-of-way of any public street in the City, is prohibited between the hours of 2:00 a.m. to 5:00 a.m. of any day during the entire months of November, December, January, February, and March. This enables us to sweep streets and plow snow, identify abandoned vehicles and provide emergency response to your home or business. You may park on the street overnight beginning April 1 until October 31.
If you must park in the street while you repair a driveway, have overnight guests, etc, contact Public Safety at 685-9858.
Overnight parking in downtown lots is by permit in designated areas only.
