There was a routing done by Tiger's group way back when. I am sure Tom will come up with something quite different but am curious how much will be dictated by the severe site.

Tiger's [or Beau Welling's] routing was pretty good, and they sorted through a lot of other options, I'm told. As you mention, it is a severe site, and since there is a housing component, too, the options for changing the routing were somewhat limited. The circulation is still pretty much the same as before, but
1) a bunch of the green sites are different [1, 3, 5, 8, 11, 14, 15, 18 on this plan]
2) the 10th hole was sacrificed to accommodations and a beach club, replaced by a new hole after what is #12 on this map
3) the sequence of the back nine changes, so the new 10-15 are 11, 14, 15, 12, the new par-3 hole, and 13 as shown on the old map [with some greens and tees moved], which improves the walk. It's just going to be a cart ride or shuttle from 9 to 10, otherwise very walkable.
The finishing stretch from 14 winds up being par 3-5-3-3-5.
It's a spectacular project -- I saw the site years ago and fell in love with it -- but it came back around kind of last minute, after some of our other projects had been pushed back due to permitting issues.
