What happens when this happens?
University of Minnesota Winter Maintenance
• If snow is forecast and temperature is in the range of 15F to 32F, streets and sidewalks pre-treated with 23% salt brine solution
• Pre-treatment helps prevent snow/ice from bonding to pavement
• If temperatures below 15F, calcium chloride w/beet solution used. Beet solution reduces corrosiveness
• Solutions spread using vehicles with 2,500 gallon tanks
