Tom MacW;
I see the problem you're having on this thread with SPDB; You probably think the discussion here is only about whether bunkering that looks like that photo on page 1 should be dug up if it had drainage and maintenance problems. Maybe that's what SPDB is saying and implying but I'm not.
I'm simply interested in knowing if bunkering like that had maintenance problems because of how it was constructed or where it was constructed. I've also wondered if some of Mackenzie's bunkering at Cypress had maintenance problems and the same goes for Egan's "artificial dunes" bunkers at Pebble.
Why do I wonder that? Well, first of all, it has nothing whatsoever to do with what I think of the look of those bunkers. To me they're undeniably and incredibly beautiful looking--a beautiful aesthetic although often quite stylized in a natural sense. But just looking at them they appear to be almost too fragile, almost too precarious sometimes in where they appear to be placed and how they're placed to withstand the forces of nature its wind and water to survive without tremendous maintenance dedication. Tremendous maintenance dedication takes time, it takes a good deal of money generally involving a good deal of repair over time.
If you have GeoffShac's book on Cypress just look at those early photos (with Mackenzie playing golf) of the sand areas so closely juxtaposed to the turf areas and look how low-profile and almost fragile some of them look. Just looking at that architecture despite its fascinating high style and beauty I'd fear that eventually (or at any time) wind and water would play havoc with it. Wind and water playing havoc with architecture like that is what maintenance problems are generally made of.
Why did bunkering that looks like that get changed and not last? I'm really not sure Tom, but I'm sure some research could give us some accurate answers. That's basically the question here to me.
If bunkering such as Egan's "artificial dunes" at Pebble were an on-going maintenance issue I'm sure that could rather easily be determined by club records or some other source etc. The same at Cypress. My sense with some Cypress sand waste areas is it was simply allowed to vegetate over to a large extent for stability and preservation. Other areas of sand even more formulized bunkering may have had wind and water play havoc with them.
Did Mackenzie, Hunter, Egan or the American construction Co expect or foresee issue or this evolution? Did they expect that some of those bunkers and sand waste areas needed to vegetate for stability or be strengthened and inured to natural forces? Did they warn the clubs that some of the more formal bunkers like the ones to the left of the green in the photo on this thread would need extra maintenance care and dedication? Or were they perhaps not concerned about that or even aware of it? These are some of the things I'd like to know.
It's certainly not lost on me that a man such as Max Behr wrote specifically about the structural integrity of golf architecture. He premised his assumptions and conclusions that if man-made golf architectural features closely mimiced the lines and formations of nature they'd have increased inherent structural integrity and that they'd last better against the forces of nature and consequently cost less to maintain and result in what he termed "Permanent Architecture".
But at least I surely do hope that this discussion does not get shut down or diverted because someone wants to assume or promote the belief that some of the well respected architects of that time could never build something that had anything less than total structural integrity and never had maintenance problems.
A good example of problematic maintenance issues would be PVGC's original fronting bunkering on #2 and #18. It was expansive and awesome looking at first, with sand sweeping up more vertically against the inclines to those greens but it had no real structural integrity and kept collapsing. In the case of #2 it took the front of the green with it when it finally collapsed for the last time before the bunkering on both holes was redesigned for structural integrity against the forces of wind and water.
As for sheet drainage Tom, it's a term and a fact you do need to know to have an intelligent and informed discussion on maintenance issues to do with drainage and golf architecture. If they teach something to do with "sheet drainage" at Holliday Inn Express then by all means check in at once!
