Street Treatments
The City uses two materials on City streets.  The first material is called "anti-skid" and is used on most snow routes.  Anti-skid can contain up to 20 percent salt, and is used to aid in vehicle traction.  The second material is used on many of the City's thoroughfares and is called "IceSlicer."  This material is a de-icer and will lower the freezing temperature of water.  IceSlicer will work down to around 10 degrees.  To view maps that show these routes, click here.

Snow Predicted

  • Anti-icing applied only to main streets when conditions permit to prevent snow from bonding to the pavement.
  • The goal of anti-icing is to prevent the snow from bonding to the pavement and forming ice.  This is done by placing material on the streets before it snows.  The material used in anti-icing is liquid magnesium chloride, an agent that is also used after snow has fallen to "de-ice" city streets.  Weather conditions have to be right to successfully anti-ice.

Snow Begins

  • De-icing applied only to main streets to prevent the snow from building up the turning into ice. 
  • Main streets plowed by heavy plows.
  • After snow has accumulated on the pavement, the Operations & Maintenance Division will apply de-icing agents to the street to prevent the snow from building up and turning into ice.  Depending on the location, either Ice Slicer, (a dry material that looks like sand but is naturally mined mix of sodium chloride, potassium chloride) or liquid magnesium chloride may be used to de-ice.

Major Snow Event - 12 inches or more of snow accompanied by prolonged freezing temperatures.

  • When there is more than 6 inches of snow main streets are treated, and after snow has stopped falling the Operations & Maintenance Division will treat residential streets as resources allow.
  • De-icing applied only to main streets to prevent the snow from building up and turning into ice.
