As legend has it, when Ross was designing the course he had assumed (or had relied on instructions) that continguous land was part of the existing club owned land. Accordingly, he made hole sketches for the land and it was incorporated into the design.
As the construction began, it became evident that the club did not, in fact, own the land and that it was privately owned. The club apparently tried to reconcile the situation by buying the land, but the owner refused to sell. This forced Club/Ross to re-route/design the course so it headed further inland.
Recently, however, the club secured ownership of the original land in question. The club had a trove of material on the holes that were originally planned for the waterfront acreage, and supposedly built holes to specification as they were planned in Ross' original routing design. I have yet to get up to see it in person, and I thought it was being done by Prichard, but I think it was hanse that did it.
