Drainage Project 7/26/18

Work continues on the drainage project and the contractor recently finished working on Orchard 4, 5, and upper 8.  After finishing Orchard 4 fairway, we had the contractor install a drain line in the left rough near the cart path that is always wet.  A significant amount of water comes from the 5 tee area and funnels down across the path into the rough.  The new drain line runs parallel to the path and will catch all of the water so it can't reach the rough.  Once that area dries out enough we will strip the worn turf, add soil and raise the grade to the level of the path, and install new fescue sod.  On Orchard 5, earlier this year the maintenance staff installed two new drain lines, but there was a small area at the very beginning of the fairway we couldn't get to.  Well, the contractor took care of that for us and you may have noticed the end of the pipe runs through the rough almost to the cart path.  This new line will also catch a significant amount of water that comes through the swale before the fairway.  On upper Orchard 8, the left (lower) fairway always seemed to stay wet and required close to 400 feet of drain line.  Our goal is to catch the water in the rough and keep it from running down the fairway.  I wasn't surprised to see all the rock, hard clay, and tree roots that came up while trenching.  Those items are not conducive to good draining soil.

In addition to the contractor performing drainage work, the maintenance staff spent a couple days finishing up the "big dig" next to the silver tee on Lakes 1.  All the old, non-functioning drainage was removed and replaced with a new catch basin and pipe.  Then the cavity was backfilled with gravel and a sand/soil mix was spread on top to allow for better surface drainage.  Turf-type tall fescue sod was again used due to it's quick rooting and other desired attributes, and should be ready for foot traffic in a couple weeks.  So far the area is dry and the drainage is working as it should given our recent rain events.
