The new town square should be about 2 - 2.5 years away from what I hear (anyone have better info?). They will begin to sell some lots and homes within a year (that's the latest I heard from some agents) or so across 466a. Final house will be sold in about 5.5 years (unless they find some more land
)
The new hospital (if approved) will be built just adjacent to the new square also in about 2 years.
When you go on 9/13 try to get someone on this board to meet you in LSL for a few drinks or dancing. They can give you the lay of the land and make you feel more comfortable. Don't be afraid to just go to places (the local pool etc.) and ask around.
Best of luck
