The Evolution of Lower 2

 We have been making big improvements to the Lower #2 green complex over the past few weeks.  This area has been plagued in the past from poor drainage and washed out bunkers.  Our first goal for this project was to replace the drainage around the green and in the bunkers.  We also installed berms to catch and redirect runoff during heavy rains.  Finally, we refurbished the bunkers so that they will be less severely damaged by heavy rains.

The first of two berms which will catch runoff and direct the excess water into the drain.
The catch basins are 30 inches in diameter and we used a 10 inch pipe to carry away the water.
We tied the basin drains into an old tile line that was intact and still functioning well.  Stamped on the pipe was a month and year: "October 1918."





 We utilized larger than normal pipe in the bunkers (6 inch rather than the customary 4 inch.)  We are also utilizing technology often found in septic leach fields.  We installed 75 feet of leach field chamber domes.  These domes are 12 inches tall and 18 inches wide and will store a significant volume of water beneath the sand during heavy rains when drain pipes become overwhelmed.

A section of 6 inch perforated drain pipe connected to the leach field chamber.
We are forming the bunkers with plywood which will be removed once the sand is installed, and sod has rooted down.
  We have been blessed by dry weather throughout the project but received a half inch of rain last night.  We will wait for the area to dry out and begin the finishing touches following the Memorial Day holiday.
Nearly ready for sand and sod!
