They could have just worked on Gavea and let the guys shoot low 60's etc and then go back to the private club it is...the entire thing was political and it's not the last time we will see this type of thing with the Olympics...a golf course is nothing to close compared to a stadium...
Gavea in winter is unplayable. Who would have buried a ton of money to fix a private club for the sole benefit of their membership?
I don't think it would have been a ton of money and they could have provided the needed work in exchange for a lease....The wet areas could be fixed without spending a fortune. It owuld have been much cheaper than going the route they chose....
I was actually asked by Gavea to consult on whether the course was suitable for Olympic play, back in 2010 -- just after the Olympics were announced. I was of the opinion that it wasn't. It wasn't so much about drainage issues, but about going back and forth under the highway and up the side of the mountain, and getting any reasonable numbers of spectators on the course ... and about the tiny practice range in between the first and second holes, with netting all around it. The powers that be were already angling to build a new course because Gavea is 6100 yards par 69, and they didn't think that was appropriate; but it was all the other "stuff" that would have made it a mess.
I did not go to see Itanhanga on the same trip, but the feeling there was that it had large-scale drainage problems that would need an expensive fix, and that there was no way the Olympics could fund that sort of investment in a private club. The Gavea members could have afforded changes if necessary; in fact, they just did them a couple of years ago, while Gil Hanse was waiting to start on the new course.
