Ben,
Wildhorse was dead flat. There is an old civil engineering rule that says the cost of bridge piers should equal the cost of bridge spans to make the cheapest bridge. In golf course drainage, I keep earthmoving and drainage costs about equal as sort of a test of cost efficiency. The flatter the course, the more catch basins you need. I believe you keep water from running more than 300 feet to avoid long, wet swales. I also believe in keeping fw ridges generally 4' high or less so golfers can see over them. And, in Davis, I was required to drain water away from the lakes and filter it before letting it into the water, plus the little lip on the lake saves a few shots from going in the water.
Within all of that, I do sometimes put basins to shape fw with greater and lesser sloped areas. In most cases, especially when flat like Wild Horse, I accept gently rolling fw and try to stagger the basins to get that random effect rather than place them every 80 feet.
Adam,
Drainage systems are designed for 1, 2, 5, or 10 year storms. Roads are designed for 10, 25, 50 or 100 year storms. The reason is mostly golf course budgets usually dictate smaller drainage because there is no real harm in letting water stand a few hours in really big storm (most golfers would quit) but I agree that every day storm, usually about 1/4 to 1/2" per hour ought to be disposed of immediately. A golf course gets a reputation for good or poor drainage, and it gets harder and harder to book tee times. So, the question is at what point does bigger drainage pipe equal a better reputation and more revenue for the Owner? Most don't suffer if their course goes down a few times a year, golfers understand that. If it gets closed in every little rain, its a different matter.
