Primary Routes: Major arterials and school access are the critical routes providing access into and out of Erie. Snow removal efforts will be concentrated on the primary routes throughout the snowstorm.
Secondary Routes: Minor arterials and collector streets connecting the neighborhoods to the primary routes. These routes are plowed only after all primary routes have been done.
Tertiary Routes: Residential or local streets are not plowed or treated except after very severe winter storms. When snowstorms leave an accumulation of 12 inches or more of snow and the snow is expected to remain for several days, snowplows will move into effected residential areas after completing service on primary and secondary streets. Plows perform one center pass.
