Boston requires you to clear snow from the sidewalk in front of your building. See city website for specific requirements and penalties.
You should also shovel around fire hydrants and handicapped ramps.
Clearing snow from storm drains helps to minimize puddles and slush.
Thank you for helping keep the Pilot Block neighborhood walkable, and reducing ticketing at the same time.
There is no use of space savers in the South End during snow storms. We are the only neighborhood that does not allow their use.
