Kyle:
I knew when I made that original post that it would confuse a lot of people, because on 95% of golf projects you are making the cut and fill balance ... if you create your features by cut, you still have to figure out what to do with the fill and how to hide it, or vice versa.
Streamsong was a rare project in that I could give some of the material we cut over to Bill so he could use it for fill ... though it was only maybe 25% of our total earthwork, and an even smaller percentage of his. Still, you will probably never find a better project to illustrate the difference between the two approaches. It took me a long time to figure out that was how Bill's approach differed from mine, and we offered to draw the plans for his course just to see what we could learn about his approach to it.
So ...
I find a green site that sits up naturally, so I don't really have to worry about surface drainage issues, and then whittle away from it, although I'm often just playing with tiny amounts of cut and fill and rarely removing any material from the green site. Bill finds a green site that sits lower, and builds up the green with sand fill to solve whatever drainage issues might result from the low spot. That's one reason my greens tend to sit up closer to eye level [which I'm trying to cut back on], and it's probably why Bill tends to have a couple of "up and over" holes on each of his routings, too. Note that the 18th hole on the Blue course at Streamsong is an up and over hole ... but it's actually NOT one that we borrowed from Bill, it's just a hole that I thought of after pondering the difference between our respective styles.
We create all of our bunkers with an excavator, and often lose the material back in the fairway somewhere. This was a major change in my style -- we started to do this at Pacific Dunes -- before that, we were building the bunkers with a bulldozer, and often raised the back of the bunker with the material from the cavity, which tended to ruin the natural feature we were building into. Bill also builds his bunkers with an excavator, and he relies on Jeff Bradley to generate enough material for the various features he wants to build out of fill.
That's all the examples I will give, for the time being. Don't want to spike the discussion.
