A parcel abutting mine contains a skydome only 55 meters high (actually only 26 meters above the ground which is at 29 meters). It's a visual annoyance to surrounding parcels, especially at night (the textures are apparently "full bright," It's not an advertising sign as all that is visible is a bright white half sphere. So I don't imagine that the rules against ad farms apply here. What can the neighbors do?
