Everett is a city of narrow driveways — triple-deckers shoulder to shoulder, a strip of pavement between them, the Mystic lying flat and grey at the bottom of the hill. When weather comes up off the harbor and the street plows throw a wall across every apron on the block, Everett Hauling & Services LLC goes to work: plowing lots and drives, shoveling front steps and sidewalks, hauling snow off the properties where there is simply nowhere left to put it. Salt goes on the entries and the path out to the car. By the time Broadway is moving again, the tenants can get out their own front doors. Packed in this tight, that is not a small thing.
