A
In an effort to inform our citizens to clear the street snow, the city adopts a snow removal plan.
Routes used by City Emergency Services come first. Secondly, connector streets will be cleared which allow citizens the greatest access to public roads. And thirdly, roads within neighborhoods will be cleared.
Snow removal and ice control will start when:
* Snow accumulates 4 inches or more.
* Weather conditions do not endanger the safety of road crew.
* Snow falls during peak traffic periods of heavy use of main streets.
Snow and ice removal will be delayed or cancelled when:
* There is severe cold, significant wind and limited visibility.
* The snowfall occurs on the weekend or a holiday and is not considered a threat to public safety. In that case, snow and ice removal may take place on the next normal weekday.
* Snow and ice may be left on roadways if melting is obvious.
Your cooperation is requested during snow removal and these suggestions may apply:
* Limit travel during storms. Travel is possible once roads have been cleared or salted by the road crew
* Avoid removing snow from your driveway into the road. Pile the snow in your yard.
* Park your vehicles in your driveways and off the road or walkwalks.
* Keep public sidewalks next to your house clear of snow and ice.
* Be responsible for removing this snow which is thrown by the snow plough(犁) from your driveways. Hopefully you can understand this inconvenience.
