Drainage Crew

Today the drainage crew started putting pipes in the low points where the green meets fairway. The greens otherwise have no drainage, and the rains proved how well water moves through the subgrade of sand.

These pipes are insurance measures. I doubt we need them because water will work through the profile vertically, but better safe than sorry.

The photo is of the current 5th green we built last year with the trenches cut for drainage pipe and gravel. You could call it the "Typical Method". Extensive drainage was used because the subsoil for this green was of a tighter material. Thanks to the native sand subgrade of the new greens, we have spared ourselves 99% of the work and the greens should perform as well or better.

Sketches comparing the two methods.

To the left the new greens with sand and how they will be drained. To the right the "Typical Method". Blue dashed lines indicate drainage.
