In response to Tommy's question, as with most things in life, the answer is, "It depends."As with most things where credit is to be assigned, I would think the best path would be to be prudently modest and call anything where you used parts of an old course a renovation.
As TD says, part of that rests in how big the rest of the changes are, i.e., use 7 holes of existing routing but rebuild all 18 to totally new character as in the project I referenced earlier? Yeah, I count it as a new course. Had it been designed by a known gca originally, I may not have. But, early in the project, I started looking into the history, and it was a local civil engineer and golf pro. The engineer told me they didn't have topo maps, because "we didn't think you needed one to route a golf course."
[size=78%]A[/size]nd the fact that we went from a "upside down bowl" type greens to a modern design themed course, etc., didn't hurt.
Suffice to say, that sort of swayed me into thinking it was a new course......also, the changes were dramatic enough that the course changed its name, which also helps the case of being a new course. When the owner wants to say they have created a new course, it sort of steers the discussion that direction as well. Not to mention, it had been a money loser and caused other problems, so the owner really wanted to sort of bury the past.
In the end, those sum total of factors made it a new course in most peoples minds. Who am I to argue with the consensus?
