To answer your other questions, everything else is built from pure dunes sand, the same as Barnbougle or Pacific Dunes ... no liners, no usga greens, no nothing. There was a lot of micro-shaping, since the establishment of the pine trees had wiped out most of whatever was there before, and since we had three crew members with a lot of time on their hands due to some construction and permitting issues.
Like every other fescue course I've done, I won't swear that it will be 100% fescue in ten years, and I don't care, as long as the playing surface is hard and fast and tight, and I can play the ball on the ground when I want to. I played 81 holes in the pre-opening event in April and it was PERFECT in that regard ... light years beyond the place I am today, for example.
The biggest risk we have taken is trying to really naturalize the edges of turf and not make any hard lines anywhere ... the fescue bleeds into clumpy areas and then into sand, and often when your ball rolls right to the edge you get a lie in broken-down turf that's a really difficult or finicky recovery. The fairways are generally very wide so if you roll off the turf it was not a good shot, but I can still see a lot of players hating the vagaries of those odd lies at the margins.
We will all be there in Feburary, you should come down and see it. Brian Slawnik ran the project and he did a hell of a job.
