Street, Sidewalk and Path Snow Removal

Street Snow Removal

The City of Boulder's snow crews are ready to respond 24 hours a day from mid-September to the end of April to snowy and icy conditions. The snow crews work hard to keep primary and secondary streets and on-street bike lanes open, using materials and equipment that help reduce the dangers inherent in winter traveling.

Primary routes are the city's first priority for plowing and applying materials. Primary routes are the major streets that run throughout the city. Two plow trucks are assigned to each of our five primary routes. (Multi-use paths throughout the city are plowed at the same time as streets.)

Secondary routes are the streets around schools and hospitals, most RTD bus routes, collector streets and streets requiring special attention in snowy conditions. Plowing of these routes begins at the same time as plowing of primary routes; however, there is one truck assigned to each of these routes.

On most primary and secondary streets, snow is plowed to the center dividing lane to prevent buildup on sidewalks. On some streets there is not enough room for center lane plowing, so snow is pushed to the side. This may narrow down travel and turn lanes.

The city strives to sweep all primary, secondary streets and all on-street bike lanes within four days following a snow storm to pick up any surplus traction materials.

Sidewalk Snow Removal

All the owners or residents of private property must have the snow on their sidewalks cleared within 24 hours after it stops snowing. Shoveling sidewalks helps prevent accidents and increases accessibility for pedestrians.

If your sidewalk is adjacent to a primary snow route, please wait until the snow plows have cleared the streets before shoveling. Plows may need to push snow onto curbs and sidewalks to keep the streets clear.

Boulder's Code Enforcement Officeers can issue a summons to persons failing to comply with the Boulder's Code Enforcement Officers can issue a summons to person failing to comply with snow removal ordinance. The fine for a first offense is $100. The maximum fine is $1,000 and 90 days in jail. Violations can result in a municipal summons issued to the responsible party and/or an abatement, which includes calling in a private snow removal contractor to clear the sidewalks. The property owner will be charged a $50 administrative fee along with the cost to remove the snow. Properties receiving an abatement warning have 24 hours from the time and date written on the top of the warning to remove the snow themselves.

Adult residents, property owners and agents are all responsible for sidewalk snow removal for a single-family dwelling, a duplex, a triplex or a four-plex. Property owners and their agents are responsible for sidewalk snow removal for other multi-family properties as well as commercial and industrial properties. Snow removed from sidewalks needs to be kept on the property. It is against city code to deposit snow (plow, shovel or coarse to deposit) upon any street sidewalk or alley.

To report sidewalk snow removal violations, please call Code Enforcement at 303-441-3333.

Multi-use Path Snow Removal

Multi-use paths in the City of Boulder are maintained to high-level transportation standards.Separate snow removal crews begin plowing the city's multi-use paths at exactly the same time that other crews are plowing city streets. Boulder Creek and Broadway paths are plowed first, followed by the Foothills Parkway path and other Greenway paths. The Boulder Creek Path is cleared by the parks department. While the Broadway path, from Baseline Road to University Avenue, is cleared by CU-Boulder facilities maintenance. All other multi-use paths are maintained by City of Boulder Street and Bikeway Transportation Maintenance (or the adjacent property owner). On-street bike lanes are cleared during street snow removal operations. 

In heavier snows, on-street bike lanes may not immediately be completely cleared of snow and ice as plowed snow builds up along the curb and gutter. Be cautious in these areas.

Cycle safely. Wherever you ride, watch for ice and gravel and wear a helmet.

Senior citizens and physically disabled persons who are unable to clear snow from their sidewalks may receive assistance through the Icebusters program. For more information or to volunteer, call 303-443-1933.

Frequently Asked Questions About Snow Removal


Why doesn't the city plow residential streets?
Boulder's sunny climate typically melts most snows in a day or two, and plowing on residential streets blocks parked cars and driveways. Also, plowing residential streets is expensive. If snow crews were to plow all residential streets, the city's plowing operation costs would increase by 200 percent.

Some homeowner's associations provide snow removal on private streets within their development. Call your homeowner's association to find out if this service is provided for your street.

What is an "accident alert"?Accident alerts are declared by the police department if severe weather conditions exceed its capacity to respond to individual vehicular accidents. During an accident alert, the police will not respond to vehicular accidents unless there are injuries, or alcohol or drugs are involved.

If you are in a vehicular accident during an accident alert, check for injuries. If no one is injured, move the vehicles out of traffic. Drivers must exchange names, addresses, phone numbers, driver's license numbers, vehicle descriptions and license numbers. The date, time and location of the accident must also be recorded before leaving the scene of the accident. You must also file a report with the police department within 24 hours.

What is Boulder doing to minimize environmental damage during snow season?
The city uses alternative deicing and traction materials. The liquid deicing agent is a magnesium chloride solution. Magnesium chloride, a plant nutrient and soil stabilizer, is less corrosive than other deicing products. The traction material is an all-natural high-performance granular deicer. No rock salt is used in the snow removal operation.

When does the city plow public bike and pedestrian paths?
Bike and pedestrian paths are cleared of snow and ice after snow starts to fall. The Broadway Path (Arapahoe to the south city limit) is plowed first, then the Foothills Parkway Path, and then the other paths. On-street bike lanes are cleared during street snow removal operations. The Boulder Creek Path is cleared by the Parks and Recreation Department at 303-441-4406.

 How can I avoid windshield damage during the winter?
Do not pass spreader trucks or snow plows, and stay three to four car lengths behind these vehicles. The city's spreader trucks have spinners which distribute traction materials.

Road Deicers

What materials are applied to Boulder's roadways?
To minimize environmental impacts of snow and ice control, the city uses alternative deicing and traction materials. The liquid deicing agent is a magnesium chloride solution known commercially as "MeltDown Apex." Magnesium chloride, a plant nutrient and soil stabilizer, is less corrosive than other deicing products.

The traction material is an all-natural high-performance granular deicer. No rock salt is used in the snow removal operation.

When are these materials applied?
Before a snow storm starts, city trucks may begin to apply a liquid deicer (magnesium chloride) on the streets. By "pretreating," snow crews can slow down the buildup of snow and ice. Once snow accumulation begins, plows start moving snow off the streets, and spreader trucks begin putting down a granular deicer for traction where needed. The liquid deicer may be reapplied throughout a storm to continue melting the snow pack.

Who makes the decision on when to apply and where to apply these materials?
The Transportation Master Plan (TMP),accepted by City Council in 1989 and updated in 1996 and 2003, has the investment in "system operations, maintenance and travel safety" listed as a "highest priority". Having snow-packed and/or ice-bound streets would be contrary to that directive and core service. The actual deployment of staff, equipment and materials is the responsibility of the Transportation and Utilities Maintenance Coordinator.

What causes the "white stains" on road surfaces?
White stains are caused by chlorides (salts) that are applied to sidewalks, parking lots and roadways, not just from what the city applies but also from people driving through Boulder with salt-laden undercarriages. Ice and salt can be picked up from driving on Colorado Department of Transportation (CDOT) and Boulder County maintained roads that run in and around the city. Salt also comes from commercial properties as many apply rock salt to driveways, parking lots and building entrances. The Boulder Valley School District and the University of Colorado also use salts for deicing on school properties. As the melting snow and ice drain into gutters, cars and buses splash this mixture around and pick it up on their surfaces. The drying melt water then leaves traces of salts or "white stains" on the road, sidewalks and parking lots.

Does the city explore other options for materials that can be used to deter the accumulation of ice and to aid traction?
The city's Transportation and Utilities Maintenance Division is constantly exploring and researching new materials that can aid in ice removal and traction control. Budgets, material availability and material effectiveness in Boulder area conditions are all examine when looking for new materials.
