Heliport...
The real question is really...would you base your personal helicopter on your own property knowing it might cause a problem with your neighbors. It isn't a question of law, rights, or privilege....simply a matter of logic as I see it.
He owns the property, there is no law to prevent him from doing what he did, and from the description of the property....he chose the best place possible on his premises.
What we have here is an implementation problem.
If he had been more sensitive to the downside of his decision, and had done a good
PR effort, all this might have been averted.
