This web site is formatted as a tool that will help you design a snow fence for a given problem location. Based on the geographic location you have selected, you will be given the data needed for steps 1-3. For steps 5 and 7 you will input site-specific parameters. Color maps, photos, and schematics are given along the way to help you visualize concepts.

There are 11 steps that you will go through for proper snow fence design:

  1. Identify the snowfall over the snow accumulation season
  2. Identify the snowfall water equivalent.
  3. Identify the relocation coefficient.
  4. Determine the prevailing direction of greatest snow transport.
  5. Enter the fetch distance for your location.
  6. Mean seasonal snow transport is calculated.
  7. Enter the fence porosity.
  8. Required fence height is calculated.
  9. Determine the attack angle of the prevailing wind (Step 4) with the road.
  10. Required setback distance is calculated.
  11. Length fence should extend from either side of the problem area is calculated.
