I never saw a 10' snow fence but putting a fence 350' away from the driveway seems ridiculous. Just get rolled 4 or 5' snow fence and put it 40 feet away or so.
I agree it's counterintuitive. I read a pretty comprehensive study by either a state or the federal government. According to the study, there are variables like relative elevation on the windward and leeward sides and the like, but the upshot was that all wind-blown snow exists in a band from 2' - 16' above the ground. If you assume a unit is 1 foot and your fence is N feet high, then a 50% porous fence placed 35 * N feet upwind of the object to be protected causes enough air turbulence to cause the snow to be dumped before it reaches the driveway. The bottom 2' should be completely open. My initial plan was to build a snow fence that was high enough to use the entire field as a dumping ground for wind-driven snow. A 4' fence only grabs 2' of the total 14' band worth of snow in the wind. A 10' fence grabs 8' worth (10' - 2' gap) and should pull a TON out of the wind. I'll see if I can find a link to the study. It was interesting reading.
