This section provides answers to frequently asked questions regarding snow & ice control.

Why do the City snowplows spread what looks like dirt on the street?

The City uses a reddish-brown product called Ice Slicer for de-icing or to help reduce ice buildup. Ice Slicer is 92% salt with 8% minerals that give it the reddish brown color. Ice Slicer will make the snow and slush look dirty but after the streets are dry there is no dirt residue. Using Ice Slicer instead of sand reduces the “brown cloud” effect in the Denver-metro area and also reduces costs for the City by eliminating the Regional Air Quality Council requirement to sweep sand from the streets after every storm.
