Snow and Ice Control

The goal of the Snow and Ice Control Program is to provide for the safe and expedient movement of traffic during inclement winter weather conditions. To achieve this, the City and County’s street system is prioritized into three categories:

Major Collector Streets

First priority: a major collector serves multiple subdivisions or areas of the City and County.   Streets abutting schools, along with those in major business, commercial, and industrial areas are also considered first priority.  All first priority streets are plowed and/or serviced within four hours of the first call.

Minor Collector Streets

Second priority: a minor collector serves a single subdivision or area of the City and County.  Problem areas such as steep hills or sharp curves may also be considered second priority depending on storm conditions. All second priority streets are plowed and serviced within four hours from the time a storm subsides.

Stop Sign Approach to First Priority Streets

Third priority: is the stop sign approach to first priority streets, not covered in the first two priorities. All third priority streets are serviced within twelve hours from the time a storm subsides.

Storm Categories and Broomfied's Response

Storm Category Description Response
I Minor Snow Storm Condition. Storms resulting in isolated icy spots.

Some de-icing as necessary.

II Light Snow Storm Condition. Snowfall of less than four (4) inches of accumulation in the street. Majority of storms are in this category. Melting usually occurs within a twenty-four (24) hour period.

First, second and third priority streets are treated.

III Snow Storm Condition. Snowfall in excess of four (4) inches of accumulation in the street, or a Category II storm followed by more than seventy-two (72) hours of temperatures of twenty (20) degrees or colder causing snow packed roads and icy conditions.

In addition to priority routes, residential streets are plowed one-lane wide down the center of the street with a single pass when residential streets reach four (4) inches of accumulation in the street. Cul-de-sacs are plowed, pushing snow from the outside edge to the middle. 
IV Severe Snow Storm Condition. Dangerous storms that produce 8” to 11” of snow accumulation in the street.

In addition to priority routes, residential streets are plowed one-lane wide down the center of the street with a single pass when residential streets reach four (4) inches of accumulation in the street .Cul-de-sacs are plowed, pushing snow from the outside edge to the middle.

V High Accumulation Snow Storm. Dangerous storms that produce 12” or more of snow accumulation in the street.

In addition to priority routes, residential streets are plowed every 8 hours two-lanes wide down the center of the street. Cul-de-sacs are plowed two-lanes wide pushing snow from the outside edge to the middle. If necessary, priority plows will continue to make passes on residential streets post-storm to clear as much ice as possible and apply additional deicing material.

New Residential Snowplows Coming to Broomfield Neighborhoods


The City and County of Broomfield (CCOB) added 10 new residential snowplow trucks or “Snow Fighters” to improve neighborhood snow service this winter. With the additional trucks, Broomfield crews will now be able to manage residential snow and ice removal.

Plowing begins when four inches of snow accumulate on the street. Crews will make a single pass down the center of neighborhood streets and through cul-de-sacs to improve access, with additional passes possible during major storms.

As CCOB transitions to this new in-house program, residents may notice some adjustments as crews refine routes and operations.

Now that the new trucks are here, it is time for another snowplow naming contest like the one held in 2021. Residents can submit name ideas at BroomfieldVoice.com/SnowFighters. Broomfield City Council will narrow submissions to 20 finalists, and the community will vote to select the final 10 names.
