Chip,
The ground is very similar in movement and elevation change to the original land in Argentina, the creekbed and pond in Austin falling at the low point of the land in Argentina, so the routing stays intact very, very close to MacKenzie's original -- the only green that gets moved substantially is the 3rd/15th (2nd/16th in the renumbered plan in Austin) because it "lands" in the creekbed -- and that actually added another element to the course and I think will marriage it to the land and improve the overall design and flexibility of the course.
James,
Think of the design as a really big reversible 9 holes -- it is 18 but you could compress it really tightly for a "private course" if you wanted. We pushed out some tees at the perimeter to allow a bit more area to accommodate more play and more options but with little play, you could literally tee it up right next to a green for the next hole -- very cool! What makes the double greens work is that they aren't all side-by-side -- some are end-to-end, others come together at 90deg, etc. It is great variety. The cross country golf will be spectacular!
Michael,
There will be tight turf around the greens in lots of places but the very clean, laser-edged effect of the Sand Belt is distinctive of their soils and ability to create and maintain those edges long term -- it is a unique environment that allows for that style to exist and it is difficult to obtain in areas where the soils are not so beneficial. The bunkers at El Boqueron may have some shaved tight into them and other sides will be rugged and more unkempt, all depending on the play and shots coming at the bunker and green in question.
