TRI-CITIES, Wash. -- Each city has a similar plan for snow removal that focuses on main roads and emergency access first. If conditions are extra difficult, a city may need to remain on priority one when the snow continues falling. First priority are always the "principal arterial streets" which include routes to hospital, and access for first responders. Minor arterials and hilly spots are usually hit next. Followed by collector streets, school zones and problem areas. Neighborhoods are generally the last to be plowed.
