But Jon, the key is what kind of flat land are we talking about, and how flat? Flat on sandy soil, like the links courses, is fine, it will naturally drain easily and it has a little bit of roll. But the kind of flat like you see at PGA National in this weeks tournament, you have to do some big work to get that place to drain at all, and that type of land is almost pan flat all around. Take the 3 courses at PGA Golf Club (and at whatever private club that is back there sharing the same property). I'd bet that before the designers got on site, those places didn't have more than 2 feet of elevation change through the whole site, with poor drainage because the soil is thick dark stuff. Flat can work OK, but it depends on the soil and just how flat we're talking about.
