Joe,
Jim Engh worked there from around 2004 to 2007. During that time, he routed 9 holes (none of which remain exactly) and then gradually tweaked that routing with Eamon Mangan. This included some initial construction work. Quite a few of those hole corridors remain in the final routing.
The project had halted by the time I got involved with Eamon in 2010. I asked to spend time on the routing to make sure we had the best solution possible, all the while knowing that there would be no appetite for wholesale change / starting again. In the end, much of the skeleton that was in place made the final cut but 1 to 3 were completely changed. Then we spent 2010-2013 building the course.
Since that time, there had been very little capital funds. But the company has now got on a much steadier footing. The condition of the new nine finally came up to that of the existing 18, hence the introduction of the Wild Atlantic Dunes course. And I finally got back down there last November to do some proper construction work, building a new practice putting green and completely reconfiguring the three tee complexes that leave from the clubhouse.
The intent is to slowly continue with this master plan over the next few years with initial focus on re-bunkering and the path network.
