It is illegal to shovel or plow snow or ice against a fire hydrant or regulatory sign, or onto the sidewalk or street. Apartment or multi-unit residence owners are responsible for clearing off-street parking spaces and parking lots within 12 hours after a four-inch snowfall. Violators are subject to fine. Although there is no ordinance requiring it, residents will not only assist police and fire personnel but can be of service to themselves by clearing snow away from nearby fire hydrants to allow quick location and access to the hydrant in the event of a fire, and by clearing snow off of house numbers and mailboxes so that addresses are visible in the event of an emergency.
