We've built native-soil greens at Pacific Dunes, Barnbougle, St. Andrews Beach, and Ballyneal.
The greens mix at High Pointe, Black Forest and The Renaissance Club was also taken from the site, but on those courses we had to process it to screen out stones or root material, so we built a "well" for a USGA green and put the material in.
But on the first four courses I named, the greens mix for most or all of the holes was just shaped in place.
I had the pleasure of walking Sand Hills before any earth was moved, and Jim Urbina and I counted twelve or thirteen holes where it looked like they didn't have to move ANY earth at all, they could just use the natural contour as it was. However, they probably did move a little here and there on most of those holes -- I've found that even when a green site looks perfect on the ground, when you put a transit on it you find that some portion has a bit more slope than you'd like. St. Andrews Beach probably has the most natural contours of any greens we have built, but on every one of them there was a little tweak we had to make somewhere ... still, it was so modest that Eric Iverson managed to finish 11 greens in the first two weeks we were on site.
