As a course chairman, GCA.com tells me (regularly) how much I don't know, although some of the gca arguments here are certainly PhD matters, not GCA 101.
In understanding the task at hand, there are two key outcomes for a course chairman - day to day conditioning, and the custodianship of the course design.
On the first matter, if you can improve the condition of the greens year round, then you are well in front. Remembering that the Course Supt knows more about these matters than the members always helps.
On the second matter, if you understand the heritage of the course, you are also in front. The course could be in better long-term shape at the end of your term than it was when you started.
As part of undertaking a Master Plan, our club was encouraged to review the historic documents and photo's over the last 40 years. I was personally disappointed that I was not aware of these documents before undertaking this work, and that I had been Chairman for nearly two years before becoming aware of them. And I regard myself as an educated person.
We uncovered the original course design, and the plans for an amendment to 5 holes made 12 years ago. The original plan was a real find. From that, we can see where we have 'lost the plot', and where we varied from the plot..
The Master Plan is likely to have a significant impact on trees on our course, something that has been on the agenda for 30 years but not pursued. It was not an initial aim of undertaking a Master Plan, but the priority was identified through that process.
This is a little OT, and relates to the other Master Plan thread. I would add that I would dislike having this Plan cast in stone for future committees. I hope that the current committee (and future committees) implement as much of the Plan, as quickly as they consider reasonable. However, if committees decide to do nothing for a year or so, so be it. If committees want to deviate from the Plan, I just hope that they do this with the current architect, or go through a process to select a new architect. This is likely to result in far less re-work, or wasted work and disruption to our golf course.
