Ally:
I don't really sign up for projects if I don't think they have anything going for them, do you? But sometimes I do take on sites that are less than top 100 material, for a variety of reasons. To try and answer your questions:
- Most compact / smallest site (how big?)
I've done a couple of major remodels where we only had 130-140 acres: Concord in Australia, and North Shore on Long Island. But most of my new projects were on spacious properties [even the "lesser" ones], or they were connected with a housing component or something. Carl's favorite, Riverfront, feels cramped today, but the total site was around 1000 acres!
I think Charlotte Golf Links [RIP] was probably the smallest, at 165 acres IIRC. Stone Eagle had some land I didn't use because it was ugly, but we fit the finished course into less than 200 acres, with 300 feet of elevation change and all the obstacles it provided. Beechtree and Sebonack lost a lot of ground to wetlands and setbacks, but they were well over 200 acres.
- Worst soil / worst natural drainage
Charlotte Golf Links, Quail Crossing, and Beechtree were all "an education in clay," built on modest budgets that didn't include a huge number for drainage, so we solved most everything with surface drainage. But they all had some elevation to work with. The Legends (Heathland) was flat and a lot of it was quasi underwater -- we managed to skirt the environmental rules by digging burns to drain those areas, some of which are now fairways. If I did that now it would be illegal.
- Least interesting topography/ features / vegetation.
The Rawls Course was an ag research field, with none of the above; there was three feet of tilt from NW to SE over 320 acres. If I had it to do over again, I'd do *less*, but that was not what the donor wanted for his $8M, so we did *more*.
CommonGround in Denver had a little bit of topography, but no real interesting topo, no features, and only a few trees of any size. But that at least it all drained somewhere to start, so we could build a relatively low-key course for half the price of The Rawls Course.
