As an alternative to constantly trying to maintain the faces of bunkers and shape of the greens, couldn't an agreement be reached with the course and designer to come back every 5 years and do a bit of touch up work?
Kalen,
In an effort to preserve an architect's work, I appointed him to the club's green committee and had a by-law passed that stated that nothing could be done to the golf course without his prior consent.
That worked as long as I was green chairman and on the board.
As time went by, and new green chairmen and boards came and went, so did the discipline and desire to abide by the by-law, let alone its intent.
You just can't obligate a membership, to embrace in perpetuity, the integrity of the architect's design or design principles.
UNLESS, the club is run by a dictator, who grooms his successor.
Some, if not many or most memberships are fickle and fad driven when it comes to golf course architecture.
Hence, preserving an architect's work is a constant battle.
