Could it be possible the topsoil that was imported was specifically for better turf growing conditions? Remember, back then irrigation was difficult at best. Now we herald sandy sites as ideal, but with the caveat that we have limitless amounts of irrigation water that can be distributed at will. That likely wasn't the case back then.
Joe, That is precisely what the topsoil and manure were for. CBM had said the land was impoverished in places and had to be top dressed, and the 10,000 loads were "good soil, including manure."

Joe,
You keep making critical thinking points. Why all the deviating from the 3 by 5 card of approved GCA talking points???
Ben Cowan, Maybe if you had actually read the posts before getting snarky you'd realize that I already addressed Joe's point in post 10.

Sven,
Thanks for posting that article, and the one on the other thread. The other one mentions irrigation as if it had just been added. I wonder if the delay with the grow in over the next year was because of lack of moisture?
