  • Snow Removal and Deicing Operations


    The Jefferson County Road and Bridge Division is responsible for clearing snow along 2,924 lane-miles of paved roads and 695 lane-miles of gravel roads in the county’s unincorporated areas. One lane-mile is a 10-foot wide section of road one mile long. State highways, private roads and newly constructed roads that have not been accepted by formal resolution of the Board of County Commissioners are not included.

    Road and Bridge’s mission is to ensure the traveling public’s safety by efficiently removing accumulated snow, providing traction materials on ice-covered roads and maintaining public access to the county roadway system, all while remaining within acceptable parameters of budget and resource allocation.

    Forecasting and Preparations

    The Road and Bridge Division is on a 24-hour, early-warning alert system. Supervisors use local, national and customized weather forecasts and databases to anticipate and prepare for the forecasted storm’s intensity. Equipment is readied for sanding and plowing during normal working hours.

    Each equipment operator is assigned a specific route for snow removal and sanding. Area supervisors determine route assignments based on road priority and the most efficient use of equipment.


    Plowing and sanding operations will take place in four phases during a storm.  The order in which streets are plowed in each phase is based on the following definitions of priority:

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


    Jefferson County does not have an ordinance requiring citizens to shovel sidewalks, but the county encourages citizens to shovel walks adjacent to their homes as a courtesy to their neighbors and for the safety of pedestrians. 

    Residents of incorporated areas are urged to check with their city governments for any policies regarding snow removal from sidewalks.  Residents in unincorporated areas of Jefferson County who live within the boundaries of a homeowners association are urged to check with their HOA for any regulations regarding sidewalk maintenance.


    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.
