#17 green drainage project


The drainage project on #17 green starts today. We will be inserting two short drain lines into the green to alleviate the severe water retention problem on the right side of the green.

The far-right side of #17 green has 4 small pockets that are very low elevation compared to the remainder of the green. These spots also perform very poorly internally draining water after nearly all rainstorms. Many of you have probably seen standing water on this green after storms. And most of you have likely seen our very large fan out blowing directly on this side of the green. We have struggled, especially in the last two years with keeping grass alive in these specific spots. The soil is waterlogged, and the roots of the grass plants cannot get enough oxygen. The result is turf death.

We have attempted to raise the profile of these low spots by adding additional sand every time that we topdress, but the deficit in height is too great to make up in this way. We have also attempted additional aeration of these areas to allow water to infiltrate and percolate better through the soil profile. But again, we were not able to improve the movement of water significantly enough. We are left with adding internal drainage to the green as the only other viable solution.











We will install 2 drain lines, one each running through the worst areas of the green. The two lines will meet in the rough behind the green, reduce to one line and then run to an existing drain. We will trench into the green, place pipe in the bottom, cover with gravel and then sand, and then replace the existing sod. Though we will be deliberate and especially cautious because we are working on a green, the process is not complicated and it is not a large scale project. While we will lose time and labor to maintain the rest of the course as we work on the project, we do not expect it to take longer than a week.

Please be aware that we will be working during play and that the right side of #17 green will be ground under repair throughout the duration of the project.



Etiquette Reminder of the Month

When parking your cart at a tee or green, please keep all 4 tires on the cart path.

 
Also, as part of a Golf Committee initiative to improve course etiquette, we have included links to videos teaching proper on course etiquette. Please take a moment to watch:





See you on the course!
