In Portland the city only clears the downtown area sidewalks. Everywhere else the property owners are responsible for clearing the way for pedestrians. Unfortunately most property owners don't do it and many pedestrians end up walking in the street.
I am renter but one half of our landlord team was out of town and I was in the mood to shovel so I did the front and side of the house. It was hard work but I enjoyed it and was pleased with the result.
A reminder to those that clear their own sidewalks to make sure you shovel at least three feet to allow for those who have wheelchairs or other mobility devices to pass. Let's all help keep our neighbors safe this winter.
