Prioritization of Roadways for Snow Removal

The County’s snow removal network and priority schedule can be viewed on the map below.  County maintained roads are plowed based on the following prioritization criteria.

Priority 1

  • Arterial roadways are always addressed first.  These are major roadways with high traffic volumes and high operating speeds that provide critical access and links within the County.  The majority of the County’s snow removal equipment is needed to keep arterial roadways safe for travel.  Clearing these roads is a top priority to ensure safe access for emergency vehicles, provide adequate land width for traffic, and minimize surface re-icing.  Because arterials are critical to the transportation and emergency needs of the County, snow removal equipment will remain on arterial roadways until the snow storm dissipates.  There are 637 lane miles of arterial roadways considered to be a top priority for snow removal in the County’s road network.

Priority 2

  • Collector roadways/school bus routes: Once snowfall subsides and arterial roadways have been cleared and are safe, equipment is deployed to plow collector roadways and school bus routes. Collector roadways distribute traffic between arterial roadways and residential streets and often serve as links between subdivisions. Collector roadways normally do not provide direct access to private property.

Priority 3

  • Local streets and cul-de-sacs: Local streets and cul-de-sacs provide for low and moderate traffic volumes within subdivisions and provide direct access to residences or private property. The plowing of local streets and cul-de-sacs is typically addressed after arterial and collector roadways have been cleared.   All local streets and cul-de-sacs are plowed during every storm unless accumulations are minor and are expected to melt the following day.
