A privacy fence is part of the site plan. It is 8 feet, but since there is an elevation difference between their property and mine, it's 8 feet on my side but only 6 feet on theirs. Basically, of all of the 13 or so abutters (it's a big property), I am getting the worst of every aspect. Light, traffic, sound, trash, clearance, activity, etc etc all come to a head at the entrance from the road, which is on the corner next to my property.
It was a business when we bought the house in 2001, but it was a small restaurant. We had almost no issues with it other than the manager being a total dillhole.
