I am a pretty good worrier, but I have explored every possibility and it doesn't seem likely that is what it is.
Can you link us to some information to support your theory?

Do this: look at all the TV preserves and fenced areas. see if any even approach a perfect circle. This is the only perfect circle I can find in TV. It abuts a straight road and three golf course holes. None of these would dictate a circular fence construction. I admit I am curious. If you and others are not, that's fine. But my curiosity does not imply some devious intent by the developer nor some ulterior motive on my part. I recall several Florida lakes that were said to have been formed by sinkholes. These lakes had a very circular boundary to them. I'm not saying that all circular lakes are former sinkholes. But I think that is a characteristic of many lakes formed by sinkholes. So, this circular sinkhole formation is common. the only difference is that this particular one doesn't have water because there is no clay/barrier to keep the water from draining. Fill dirt could have been used to level the ground, then turned into a preserve.
"Many ponds and lakes in Florida are a result of sinkhole formation. The characteristics of a sinkhole lake can give clues as to how it was formed.
A circular lake indicates that the lake evolved from a collapse sinkhole. A shallow circular lake results from impermeable sediments washing into a subsidence sinkhole. If a lake rests above groundwater level, it is above a confining bed."
"On the surface, sinkholes may develop progressively as subtle, bowl-shaped depressions"
