  • Road and Bridge's Snow Removal Policy


    Plowing and sanding operations occur in four phases during a storm. The following definitions of priority determine the order in which streets are plowed in each phase:

    • Priority 1 - Main arterial streets that provide for high traffic volume.
    • Priority 2 - Major subdivision collectors, school zones and school bus routes.
    • Priority 3 - Residential or other local roads that carry moderate to low traffic volume.
    • Priority 4 - Cul-de-sacs or other dead-end roads carrying very low traffic volume.

    Phase I

    Initial opening of all Priority 1 through 3 streets, in that order. Storm severity may delay response time for Priority 3 streets because initial opening of major arterial streets requires multiple lanes to be plowed in each direction.

    Phase II

    Plowing and sanding of problem roads having steep inclines, curves, bridges or overpasses. Widening of any Priority 1 through 3 streets deemed necessary. Repeat plowing of all streets initially opened as snow continues to accumulate. 

    Phase III

    Removal of packed snow and ice on all Priority 1 through 3 streets where possible and deemed necessary as snowfall accumulation stops. Plowing and sanding operations on Priority 4 streets will occur as resource availability allows. It could be several days after the snowstorm has ended before Priority 4 streets are initially plowed; intermittent sanding as necessary by road priority.

    Phase IV

    Storm event is over. Continuation of widening operations to improve safe travel and prepare for additional accumulation during subsequent storms.

    Application of Traction Materials

    Sanding of most roads is limited during heavy snowfall because the sand is quickly covered and removed as additional plowing occurs. When applying sand, special attention is given to road sections posing specific safety concerns. These include, but are not limited to: school and hospital zones, police and fire stations, bridges and overpasses, turn lanes, acceleration or deceleration lanes, approaches to intersections that are stop-sign or signal controlled, curves, steep grades, heavy traffic areas, areas of ice accumulation, speed bumps and areas with other known problems.

    Snow Removal Clarifications


    Driveway approaches affected during Phases I, II and III are the property owner or resident’s responsibility to clear. When snow removal or widening in Phase IV is being carried out, driveways previously opened by the homeowner will not have additional snow plowed into them.

    Mailboxes and Fences

    Mailboxes, newspaper delivery boxes or fences placed alongside the traveled roadway are installed at the owner’s risk. If an operator strikes a mailbox or fence with a plow, the operator will report the accident, and we will make repairs as soon as possible. Mailboxes and fences damaged by snow load during normal plowing operations are not the county’s responsibility. If plow strikes a mailbox, it will be replaced with a standard, rural mailbox. Postal regulations require residents to clear snow in front of mailboxes to allow for mail delivery.

    Snow Pushed onto County Street or Right-of-Way

    The practice of pushing or throwing snow onto or across Jefferson County streets endangers the traveling public and snowplow operators. Residents and private contractors may receive a warning or summons for snow pushed onto county streets and rights-of-way from sidewalks, driveways, parking lots, etc.

    Vehicles Parked or Abandoned

    Streets on which vehicles have been abandoned or otherwise parked, restricting the safe and continuous operation of snow-removal equipment, may not be plowed until the vehicles are removed.
