Great work Erin! I had a tennis court on my property (earlier property than I own now) We had a smaller clearance than that and a high fence. We were located on .9 acre, which included a complete layout with landscaping, pool, horse area, etc. I believe Erin's estimate to be high.
Googleearth 8044 Indian Creek Drive in Orangevale for a layout if you want to see a visual. I think I still have the information on who built it...if that helps..
