The site is about 47 acres of woods and meadow. It was at one time part of an estate and had a home, garden etc on it.  This is where the new site is going.   We can easily protect 40% of the site that is wooded.  Does a home/estate qualify it as previously developed?   If considered a greenfield and we protect 40% of the site then do we have to go to option 2 and pay the fee?
