Snowplow

Snowplow Priorities
The city makes every effort, to the extent possible with current manpower and funding, to pretreat main arterials for ice prior to major snow events and to remove snow and ice as quickly as possible during and following a storm event. City crews work in shifts around the clock to ensure that our streets are safe and passable.

Priority Routes

The city  is responsible for the maintenance of approximately 241 lane miles of arterial, collector and local streets.

The city is divided into four main sections for snow plowing. If possible, crews will be assigned to the same route each snowstorm throughout the winter season. This will allow crews to become familiar with their routes and any trouble spots within those areas, which will result in more efficient snow plowing efforts.

Snow removal priority is a volume-based plan, focusing on clearing streets that benefit the greatest number of users first.

Northglenn Street Snow Removal Routes

Based on that approach, the following procedures will occur under most circumstances:

First priority - Arterials
  • All lanes, including turn pockets, will be plowed and treated with anti-icing materials as needed. Arterial lanes include: 104th Avenue, 120th Avenue, Huron Street and Washington Street, among others.
Second priority - Collectors, school zones and steep hills
  • One lane in each direction will be plowed and anti-icing materials applied as needed. Collectors are streets that connect directly to an arterial.
Third priority - Local collectors
  • One lane in each direction will be plowed and anti-icing materials applied as needed. Local collectors are lower volume streets that connect with major collectors or arterials.
Fourth priority - Residential streets
  • Plowed if accumulation exceeds 8 inches. A single pass will be plowed down the middle of the street. Anti-icing materials will be applied on hills, curves and intersections as needed.

Exceptions: Varying weather conditions may require plows to return to first and second priority streets prior to servicing third and fourth priority streets. The focus is to provide service to the greatest number of users first.

Emergency vehicle access will also be a high priority. Residents experiencing a medical emergency should call 911. City crews will work in conjunction with police, Northglenn Ambulance and the North Metro Fire Rescue District to provide emergency access.

Snowstorm Classifications
The city uses the following snowstorm classifications to help determine what kind response will make to the impending weather, as well as to anticipate the effect it will have on transportation in the city. The predicted snow totals are determined by the National Weather Service.

Type I: Up to 4 Inches Accumulation
  • Action: Snow removal is handled by city crews. Work is generally completed within a normal shift, however, some overtime may be required to complete operations.
  • Impact: Minimal. Almost all of the roadway network should be accessible with little travel delays.

Type II: 4 inches to 8 Inches Accumulation
  • Action: Snow removal is handled by city crews and may require extended work hours or the addition of a second shift.
  • Impact: Moderate. Some travel delays should be anticipated. Low volume streets may temporarily experience difficulty accessing collector or arterial networks.

Type III: 8 inches to 12 Inches Accumulation
  • Action: Snow removal is handled by city crews supplemented by qualified Colorado CDL operators from other departments. Rotating shifts will be established for 24/7 operation. Continuous operations will occur until all city streets have been plowed.
  • Impact: Significant. Travel delays will occur throughout the city. Minor arterials and collectors may experience limited travel, capacity reduction and major delays. Local streets may be impassable or accessible only by 4-wheel-drive vehicles.

Type IV: 12 Inches or More Accumulation
  • Action: Plow shifts are established for continuous operation. All qualified Colorado CDL operators will work rotating shifts. City crews may need to be supplemented by contracted services.
  • Impact: Severe. Major delays may occur throughout the roadway network. Many roads may be impassable. Traffic capacity may be severely reduced. Snow removal efforts will be focused on arterial networks and on providing access for emergency vehicles. Local streets may be impassable for extended periods of time.
