Alternate side parking begins at 5 am every morning of the snow season, regardless of whether it snows or not. Therefore, you should plan to park or move your vehicle after 5 pm each day to the side of the road that will be permissible to park the following day.
Think of it this way: if it is 5 pm on November 11th, and you’re parked on the odd side of the street, you have 12 hours to move your vehicle. If that does not make sense, please refer to the first Alternate Parking Ordinance question.
