You have to clear a path for pedestrians. Not like many people walk anymore except the mailman, but you still have to clear your sidewalk. If you don't and a slight thaw comes then re-freezes you are going to have ice. If someone falls from ice on your sidewalk you/the homeowner can be sued.
Yes, property owners do have a legal obligation to clear snow from their sidewalks.
