While snow is falling, the city doesn't accept complaints about snowy or icy sidewalks.
But after it stops, every property owner is required to clear a path on their sidewalks for pedestrians to walk on and also has to remove the snow from sidewalks next to bus stops and hydrants. If they don't, they can get a summons.
- If the snow stops between 7:00 a.m. and 5:00 p.m., property owners must clear their sidewalks within four hours.
- If the snow stops between 5:00 p.m. and 7:00 a.m., property owners must clear their sidewalks before 11:00 a.m.

Snow or Ice on Roadway Removal
When it snows, the city has a plan that it follows for clearing snow and ice from priority locations: highways, snow emergency streets, bus lanes, and other primary routes.
After those locations are cleared, the city spreads salt and plows all of the roadways.
