Bill, to address the inconsistencies of your bunkers, and to make them uniform requires alot of money and work. Some are deep some shallow, some face the sun, some face north, some get wind, some don't, some get lots of play, some never get hit in, so they can change daily if not hourly. To monitor and spend the time and effort to keep up with the changes and adjust each bunker is a task most cant afford, and would be noticed only by a few.
A separate irrigation system would make them uniformly wet. I, ahem, do have some dedicated irrigation to bunkers, which I don't now have the permitted water resources to run with any frequency. Some, me included, have handwatered and rolled certain bunkers. This is a temporary and ridiculous practice that can't be sustained for daily play unless the club has retarded resources. It doesn't make financial sense for the overwhelming majority.
There there are the large upfront construction costs either in terms of shaping, lining, trenching, piping, graveling, (sometimes a 4" gravel bed--expensive in our neck of the woods when the nearst gravel is 4 hrs away). Sand in our neck of the woods is rounded and on the fine side. Selecting the perfect sand from god knows where would help. Yes, Ohio has the best!
Our sand is occasionally called "thin" despite the fact there is 50' of sand below the surface.
Thanks to the economy and common sense, we recently saved about $150k by not "addressing" these "inconsistencies" based on a vocal few who have no idea of the costs.
They are hazards, and only thousands of dollars of upfront and continuing dollars can please everyone.
For those who aren't resource-unlimited, spending more than daily labor, and occasional sweetening of sand is unreasonable.
"the #1 complaint about our course has always been that the sand in the bunkers is "inconsistent," whether that means some is dry, some wet, some hard, some thin, some thick......."
Its a hazard, Bill, stay out of it
By the way, I pass your course at least twice a week and it always looks uniform and immaculate. It looks very well built and maintained. Kudos to spraying Tifdwarf with dye instead of overseeding. I know you had a l role in it, good work.
