1. Dealing with Winter Snow Maintenance 2015 SDATAT Road Conference By : Ken Skorseth SDLTAP Special Projects Manager

2. Presentation Overview  Eliminate “Snow Traps” whenever possible  Define Snow Routes  Who Calls for the Plow?  Good Plowing/Winging Techniques

3. Snow Trap - Just a few little trees???

4. Here is the problem caused by those trees by end of winter:

5. This road was clear for miles except for this large drift!

6. This is all it took to cause the problem:

7. It doesn’t take much to start a drift

8. Potential problem

9. Bales too close to R-O-W!

10. A bad winter and trees, buildings and machinery too close to the road Can’t change now, but don’t allow new building like this.

11. Other Potential Snow Traps  Hay stacks beside the road?  Machinery parked near the road?  Buildings built near the road?  Residents pushing snow from their driveways and piled at edge of road?  Other?

12. Which Roads are Opened in the Winter?

13. County Roads Township Roads

14. County Roads Township Roads Snow Routes

15. Who Makes the Call for Snow Plowing?  Board Chairman or?  Avoid confusion – plan ahead.  Contractor determines when to plow?  Can work if trusted to make good decisions.  If township owns a grader, does operator determine when to plow?  Again, communicate, have a plan.  Other?

16. Plowing and Winging Principles  A critical issue to understand.  Careful about what you ask for.  Proper use of the snow wing will help in later storms or make the problem much worse.

17. A little history:

18. Ridging – A Bad Example!

19. Start Right With the First Storm! Nice Example of casting snow off of road without leaving any ridge to catch drifting snow.

20. Another Good Example

21. Nice winging technique

25. Use of under blade, V-plow & wing simultaneously – requires skill!

27. First break-through

28. Nice job

29. The mailbox – you have to deal with it

30. Running past a driveway

31. No more ridge than this if possible

32. Could this have been avoided?

33. The truck is fast, but winging needed soon

34. Winging or a blower needed before next storm

35. Taper or benching is better

37. Holds too much snow in next storm

38. Policy on helping the public?

40. When it really gets tough!

41. Keep the snow off the road in late winter

43. What happens if you don’t

44. Be careful!
