Spokane County's maintenance department provides snow and ice control for all county roads. Snow removal is organized by the following priority system:
Priority 1 - Major Arterials
Priority 2 - Secondary Arterials
Priority 3 - Residentials
Priority 4 - Not Plowed

When the roads are plowed, snow must be removed to the curb line to ensure mail delivery and that snow-melt or rain water can reach drains. Trucks providing traction sand (mixed with road salt and granular deicer) usually follow the plows. A liquid deicing solution instead of sand may be applied to the more heavily traveled arterials depending on weather conditions and temperatures. Liquid deicer is used to prevent the snow from bonding to the asphalt and it also helps to minimize the amount of dust particles in our air.
