Snow Etiquette

I'm finding that many people have no idea about snow etiquette and I'd like to share some of my experiences and also ask others for their experiences and opinions on this topic.

For years my neighbor across the street from my home has plowed his driveway directly across to the front of my sidewalk.  When I told him I don't want him to do this, he responded, "it's just snow"   Needless to say, it doesn't make for good neighbor relations and that's too bad.

I just bought a commercial property on Seeley Street in Bethel and my neighbor plowed half the snow from his 19 car parking lot over his 2.5' high retaining wall into the 4' X 10' area between my building and the 10' retaining wall on my side of the property.  It's obvious he's been doing this for years judging by the bent metal pipes on the wall.   When the office was contacted to have the situation remedied, they asked if I saw it being done and then suggested maybe it was the nearby church or town that plowed the snow over the edge.  Hopefully, they don't do it in the future but, again, this kind of thing isn't good for neighbor relations and their office tried to make it look like I was the bad guy.   I have a 4' high retaining wall onto my neighbors property at my home and I take great efforts to make sure the snow doesn't tumble over the edge.  I have 7' high piles of snow in my yard but that's the nature of the New England winter and we have to take the snow in stride.

These situations and knowing I now have had snow removal issues at both of my Bethel properties led me to believe there are probably many others out there who would relish a discussion on the topic.  I'd be interested in knowing what kinds of situations others have experienced, both good and bad, and if they've been successful in resolving any issues.
