All city streets get plowed when snow accumulates to 4 inches or more in a single storm. The following conditions may give the impression that snowplows have not cleared the street:
- Snow gets packed down on the roads from vehicles prior to snow plowing. In this case, snowplows clear the top layer of loose snow or slush from the surface, but are unable to clear away snowpack and ice down to the bare pavement.
- Ice on the road may thaw rapidly, leaving slush and loose snow in the roads.
- Snow cleared from driveways is illegally cast into the road (SCC 4-5-160C).
- Vehicles parked on the roads, and other obstructions in the road, prevent the plow from adequately clearing the roads. (SCC 11-20-050)
