Tom Mac,
Who was the developer?

Where is the mission statement now?
Were they going to recreate the 12th at Garden City there?

Was Doak going to be involved?
It's probably a good thing that they never did build it because it would have really compressed things together a little too tight. Lets just say to the point of being unsafe, even for me.
What would have had to happen was a drastic compression of both the New and the Jubilee, meaning that they would have had to take and reroute the courses between some narrow areas with little width and length. I'm not saying it couldn't have been done. I think it was better that they didn't.
If the "Modern" was supposed to go where you are describing, that area was razed long ago, eliminating the interesting land that may have been there. You can see it in a lot of pictures, the high sand hills that formed close to the ocean front. Even some of the Jubilee plays on some of it, (and they are probably the most picturesque holes on all of the courses combined, #'s 8 green 9, 10, and 11 tee.) There may be room there, but along with it comes a lot of areas that have been somewhat bulkheaded with rocks (the Eden side) and other arsenal to wade off the rising tides that would come somewhat near it.
Since I started writing this, I have scanned from my map of the Saint Andrews courses (Courtesy of Daryl "Tur" Boe who kindly got me a copy to make-up for the one that was stolen at King's Cross) so you can see for yourself, that theland was in fact there, and it is now "architecturally" gone. That is unless you name is Tom Fazio or Russ Jones..I mean Rees!:)
Sorry for the creases, it has been opened one too many times!:)
