During snow/ice weather events, it’s also important to:

  • Know who to call and when:
  • Give snowplows and deicers plenty of room to work. Allow for a minimum following distance of 200 feet from the plows and deicers while they are working.
  • If you must pass, take extreme caution and beware of the displaced snow and ice, or sand spray.
  • Vehicles parked along all major arterials and emergency routes must be moved off the street. It is recommended for them to be moved when snow is in the forecast.
  • Keep drainage inlets near your home clear of leaves and debris during the winter months to help reduce the chance of flooding.
  • Try to keep garbage bins and other obstacles out of the street when the roads are icy or covered with snow.
  • Obey road closed signs.
