Ben S.:
"I am interested to know how the design of this green was developed."
Okay ... since you asked.
Of course we started with the idea of Macdonald's "Short" hole, the sixth at National. I have seen the hole at Royal West Norfolk GC in England where his idea supposedly came from, but though I love that course, I don't think that hole is anywhere near as interesting and complex as the version at National.
We knew we would be playing in a crosswind from right to left, sometimes helping, so we determined it would be important to keep the back of the green raised high ... there was already a ridge in back. We started with a natural blowout to the right of the green for the right edge, and worked off that.
As for "design development" there were no CAD drawings or plans -- we never do those for greens if my own associates are there to do the shaping, because I don't want to tell them something stupid and get them off track. I just tell them what I'm after (as vaguely or specifically as warranted) and turn them loose. So ...
After it was cleared of gorse with a trackhoe, the whole green was shaped by Jim Urbina, in about half a day. At some point a few days later, after Mike Keiser had looked at the raw version, Jim went back on it and added a couple of ridges and pockets with a trackhoe to make sure there were no putts that would get away from you completely ... that there was always some way around ... in anticipation that I would do the same when I got there.
And that's all there was to it. I never told him to make it 17,000 square feet, just big. When I got back to see it I was leaning toward lopping off the front left area (where the flag is shown on the picture), because this was the first green we'd built and I didn't want to get going in a crazy direction on other holes. But, everyone else on site from Bahto and Klein to Keiser and Hepner and Schneider seemed to like it as it was, so I let it stand.
Probably half or more of the greens on my courses today are really designed by one of my associates. (Four or five of them were even designed by Jack Nicklaus.) But, I do spend half a day or more on every one of them, making little tweaks to be sure they play properly, adding or subtracting area, and stopping them from going off the deep end. The green pictured is a rare example where I really didn't do anything to it. So if it doesn't work ... blame Jim and the committee.
P.S. Just kidding there. I get more than my share of the credit for our work, so I have to accept the blame as well. But, as I sometimes remind my associates, while they have a chance to make our work better, I'm the one who stops them from building a green that doesn't work, so they get a small share of the credit but none of the blame.
