Jim, you may need to borrow a page from the Colorado Dept of Transportation. They have constructed "avalanche shed's" over many sections of highway where regular and repeated avalanche activity occour. It seems as though the "hedgeapple avalanche season" is a regular event. The good people of the HARGRR may wish to consider these structures over critical city centers and protected shelter areas.

I'm sure federal funding is available.
