Mark Fine,
Any plan that is on the board for ten years is prone to revision from a variety of forces and sources.
In the northeast, closing a course on October 1 and reopening it on April 1 poses no substantive disruption to the membership.
In Florida, Closing a course on April 15 to May 1 and reopening on October 15 to November 15, likewise provides no substantive disruption to many courses.
So I don't have major concerns with being able to get the wodrk done. In addition, when doing work over time, can you get the same contractor, the same crews, the same grass, the same sand, the same soil, the same materials, etc, etc.. Extending the time of a restoration to 10 years is almost GUARANTEED to insure that the plan will fail in one form or another.
From a financial point of view, if funding is tracked to construction, year by year, the project will almost certainly fail. There will most certainly be crises that invariably divert the funds to other areas, thus putting the restoration on the back shelf, perhaps forever.
And, it's doubtful that the finished product would mirror the original plan, created 10 years ago.
As to Lehigh, I couldn't comment on the specifics of the plan or the results.
I've been told that the course did not suffer from dramatic disfiguration and as such, not much in the way of restoration was needed.
Could you describe the alterations that took place prior to the club embarking on its restoration, the restoration plan, and the results of that plan in the context of the original intent.
