Snow and Ice Control
2019-2020 Snow Removal Program
Stay informed and be prepared.
City of Boulder snow crews work 24/7 to keep more than 300 miles of roads and multi-use paths clear and safe during snow and ice events.
- 52% of streets and 100% of multi-use paths are regularly cleared by city snow crews, with the University of Colorado and other entities clearing portions of the path system.
- The city prioritizes emergency access routes, major arterial streets, and access to hospitals, schools, transit and critical infrastructure, as well as neighborhood streets with steep slopes.
- See the interactive snow route map for more information.
- Snow and ice removal requests for streets that are not regularly plowed may be made through Inquire Boulder.
- The Transportation Maintenance team will inspect the area and will service depending on conditions and after prioritized streets and multi-use paths are cleared.
Make it clear within 24 hours: snow and ice removal guidelines for residents
Help make travel safe for everyone! City of Boulder property owners, landlords and tenants are required to remove snow and ice from their sidewalks within 24 hours after snow stops falling. Failure to remove snow from sidewalks before the 24-hour deadline may result in fines and having to pay for a private snow removal contractor.
- Check the National Weather Service snowfall report and look for the last recording of "Light Snow" or "Snow" to determine when your sidewalks need to be cleared.
- Don't plow or shovel snow into any street or alleyway.
- Plows may need to push snow onto curbs and sidewalks to keep the streets clear.
- Report sidewalk violations through Inquire Boulder or by calling Code Enforcement at 303-441-3333.
- Contact Cultivate (303-443-1933) if you are a senior and need help clearing your sidewalk.
When conditions allow, roads and paths are pre-treated to help reduce the buildup of snow and ice. Snow crews may also apply an anti-icer before a storm to minimize icy road conditions. If a storm starts as rain for multiple hours, pretreatment is ineffective because rain dilutes it and washes it off roadways
Depending on the weather, the city uses several types of de-icers:
- Salt Brine is a pre-treatment that helps reduce buildup of snow and ice
- Ice Slicer RS, a granular de-icer, is made up of complex chlorides that dissolve over time
- Meltdown Apex, a liquid de-icer, is a magnesium chloride solution, a plant nutrient and soil stabilizer that is less corrosive than other de-icing products
The city strives to sweep all primary and secondary streets and on-street bike lanes within three days of the end of a snowstorm to remove any surplus materials.
Be Aware of Accident Alerts
During an accident alert, the Boulder Police Department will not respond to vehicular accidents unless there are injuries or alcohol or drugs are involved. If you are in an accident during an alert and 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. Record the date, time, and location of the accident before leaving the scene and then file a report with the Boulder Police Department within 24 hours.
Whether traveling by car, bike, foot or bus, consider the following reminders:
- Give snow plows and spreader trucks plenty of room to operate.
- Allow for more stopping distance on icy or snowy roads when behind other vehicles, including snow plows and de-icing trucks. Loaded de-icing trucks weigh up to 54,000 pounds, drive slowly and have spinners that distribute materials across two lanes of traffic. Allow for adequate stopping distance and stay at least three to four car-lengths behind to avoid windshield damage.
- Do not pass snow plows or de-icing trucks, which are both wider than one traffic lane. This will help avoid potential accidents, windshield damage and limited visibility caused by flying snow and ice.
- Consider other transportation options during snowstorms, which helps reduce the number of vehicles on the roadways and gives plow trucks more room to operate.
- See additional safety tips for walking and biking in the snow.
Generally, like other Front Range communities, the city does not usually plow side and residential streets since most snow usually melts within a day or two and because side and residential street plowing would significantly increase costs, impacting other high-priority services.
The city began its residential street plowing program during the 2014-2015 snow season, incorporating select streets that were prioritized based on an analysis of residential street slopes. When the forecast calls for eight or more inches of snow or three days of temperatures below freezing, the city deploys two trucks to plow residential streets in 10 predetermined areas with steep slopes or a lot of shade (see map). This residential street plowing program is funded from a 2013 voter-approved tax initiative that provides additional transportation funding from 2014 through 2030.
After priority streets are cleared, snow crews will respond to requests for snow removal as conditions and availability allow. Emergency requests and requests from emergency personnel will be prioritized before other requests.
