Tom:
Not sure anybody but you and I are reading this thread anymore, but I will explain anyway.
Mostly, we were asked to stick with Fazio's routing because they had already gotten erosion control permits based on that routing, and they did not want to go through an 18-month process to change them all around. That, and most of his routing was pretty good considering the parameters ... having the existing clubhouse site, and the driveway into the club splitting the property lengthwise, made for a limited number of routing solutions.
The one major change I made was to Fazio's tenth and 18th holes. His tenth would have played up the hill backwards on the current 18th, but the mystery to me was that his 18th was a dogleg left par-5 playing from today's tenth green down toward the 9th green, then around the pond toward #9 tee. I did not understand how that was going to work, in particular why people wouldn't just play down their tenth fairway on the more direct route.
I explained my thought when I interviewed for the job (having seen a model of the routing for about an hour beforehand) and apparently none of the founders had really thought about it before and it got them thinking. They asked me how to fix it and I said it was a triangle so it needed to be three holes ... we reversed the holes (gaining a hole in the process) and that allowed me to change Fazio's #3 and to eliminate a downhill par-3 between todays third and fourth holes.
The gas line crosses the other end of the golf course (across the crest of the fairways on #2, 12, 13, 14 and 16) so it was impossible to make cuts there, which explains why those holes are all of the "up and over" variety.
