I would ask the owners, it might back up to an area near the Reserves, but it doesn't mean there's construction going on nearby. It's a pretty big place, there's not THAT many homes being built, I just went running all through that area of the resort in Nov.
If you have any addresses in mind, PM me, I'll be there on Monday and I can check it out for you while there and let you know if it's close to it or not!
