One thing that's worked great for me over the years, is to shovel/snowblow all the way across the road, and do so several feet on either side of your property in addition to yours. Then when the plow comes by, the snow he accumulated already will be disposed of before he gets to your property, and when he goes the other way, it will happen the same way.
I'm picturing an ally here, so I don't mean if you have a real road to shovel the snow into someone else's problem. A rural road would be similar I imagine.
I tried that but the plow is too big and it made no appreciable difference in the size of the berm...and my neighbor across the street stood in his doorway with a scowl on his face so I stopped. [heh,heh]
