Products Used In the event of a snowfall, freezing rain, or frost event, a sand/salt mixture is generally applied. Crews adjust materials depending on the prevailing temperature and weather conditions. The City uses salt brine to pre-wet the dry sand/salt mixture. Salt brine is manufactured in-house and is a water and salt mixture (23% salt concentration).Anti-icing is a proactive approach to fighting snow and ice and consists of applying a liquid de-icer only to streets prior to or at the beginning of a storm to prevent snow & ice from bonding to the road surface.In 2007, the City began anti-icing with salt brine on hills and other high hazard locations using a one-ton truck with a 500 gallon tank and spray bar. An additional truck was added to the fleet in 2008. Anti-icing is currently in the trial stage.
