Front 9 Greenside Bunker Renovation

The Front 9 greenside bunkers were recently renovated using the Better Billy Bunker method.  All 22 bunkers, making up 21,650 square feet, were renovated in 3 weeks by Forefront Construction.  The weather couldn't have been better for the project and the cooperation from the Members allowed the project to fly by without any major setbacks.  The following is a summary of the step-by-step process.

All of the old contaminated bunker sand was removed and dumped on-site.  Some of the sand was stored in the dump facility to be used at a later date.  The remaining sand was placed on holes #3, 4, and 5.  In front of the creek on #3 used to be a gravel road used predominately by the maintenance department.  Sand was placed on the road to allow the bermudagrass to grow over this area and eliminate the shortcut.  The remainder of the sand was placed on holes 4-5 in the rough where the ground conditions were hardpan.  The sand will be spread out evenly and then topsoil will be brought in and hydroseeded with a 4-way cool-season blend.

  
Drainage was then inspected and replaced as needed .

A 2" layer of gravel was then applied to the entire bunker.

The grates seen in the photo were 2" thick.  The crew would place these grates in an area to make sure they were at a 2" level and then pick them up and move to the next area.  Here is a picture of the leftside bunker on #9 with gravel.

The next step was the application of the Better Billy Bunker polymer.  A licensed spray applicator, solely for the BBB polymer, was brought in to perform this task.  There was a 3-man crew who performed the job.  Robert sprayed the bunkers while another crew member held the hose.  The third crew member would rake and smooth out any imperfections to the surface right before the polymer was applied.  The polymer was heated during the process with a diesel forced air heater that was placed right against the barrel being used.  Heating the polymer allows the product to be pumped out of the barrel and sprayed without interruptions from clogged lines.

 

The following picture shows the bunker on #9 with the right-half sprayed and the left-half not yet sprayed.

Here is the right-side bunker on #8 with the entire bunker sprayed.  Stakes were put up to deter golfers from walking on the freshly sprayed polymer.  The polymer was given a 24-hour period to dry before sand was applied.  Every bunker was also inspected to make sure that the polymer was thick enough and that there weren't any imperfections, such as a golf ball making an indention.  A few ball marks were spotted and these areas were resprayed.

Once the polymer was fully inspected, fresh sand was placed in the bunker.  The sand is 4" deep and consistent throughout the bunker.

The entire bunker was compacted numerous times.  Water would be applied and the sand would be compacted again to make sure the depth was consistent at 4".

Every bunker was then checked thoroughly to make sure the sand was at the proper depth.

Finally, here is the bunker after having been raked.

The process couldn't have gone any smoother.  As mentioned earlier, this is a testament to the construction crew and their professionalism and the patience and cooperation from the membership.  While the new bunkers will take a little time to get used to playing, we hope everyone is happy with the final results.  We look forward to continuing this project in 2016.

Berm Project #14-15

The creek that runs through holes 14-15 has been an ongoing problem for many years and effected both the playability and aesthetics of the golf course.  Major rainstorms channel water, sediment, rocks, and debris down the creek with tremendous volume, which leads to overflowing and blockages.  Water and material then would run over onto the golf course and pose playabilty and maintenance issues.  We believe that these issues have been alleviated with the creation of the berm in-between holes 14-15.

Material was moved from the creek bank along 15 over to the side of the creek bordering hole 14.  This material was used to create the berm on 14.  In addition, material was removed along 15 creek bank, where the creek turns toward the pond, in order to widen the creek at this juncture and disperse the water.  We believe this will reduce the flow and force of water and sediment and help alleviate the impact placed on the berm.

The berm along 14 is approximately 250' long, 6' wide, and 3' tall.  120 tons of recycled concrete was placed along the berm to stabilize.  The concrete has a wonderful color and similar appearance to rock.  In addition, we're very happy to be able to reuse this concrete for such a needed cause.  The berm has been seeded and strawed and the seed is germinating as planned.

We would like to thank Chesterfield County with all of their help with this project.  All of the 120 tons of recycled concrete was donated by the County along with some labor.  We realize that this creek will continue to need maintenance and improvements, but we believe that this berm installation will improve the playability on #14 while also adding to the aesthetics of the golf course.

Golf Course Update

The golf course is coming in nicely due to all the hard work performed by the GCM staff. I just wanted to take the opportunity to elaborate on a few issues on the course. I have been receiving a lot of questions regarding the patches in the fairways and large areas of turf that are thin/dead. The patches on a select number of fairways are Spring Dead Spot. This is a perennial disease that occurs on bermudagrass and different factors play a role in the severity. Cold winters, poor drainage, and soil compaction are just a few factors that can increase the severity of the disease. Fairways on #4 and #17 were the worst hit with this disease this year. Therefore, we will apply fungicides in the fall preventatively on these two fairways and a couple other holes and monitor if this practice helps combat the disease.

Hole #10, once again, didn't fair well over the winter. The majority of the fairway/left rough on the hill is in the shade for most of the daylight hours in the winter. This area of the hole also receives a great deal of foot traffic whenever it snows due to sledders. The foot traffic compacts the snow and delays melting. Excessive shade and cold temperatures are a combination that can lead to winterkill. Virginia Tech has found that Vamont bermudagrass performed well coming out of dormancy this year. However, Tifway struggled in areas susceptible to winterkill. The turf areas on #10 that experienced winterkill are predominately Tifway. In addition, the north-facing slopes on #12 and #16 also experienced winterkill. The following are a couple articles detailing the severity of winterkill experienced in the Mid-Atlantic this year:

 That being said, we are working to fix these areas. Fescue sod was laid on the left rough on holes #10 and #16 in place of bermuda. The fescue will perform much better over the winter being in shade and on a north-facing slope. I'm hoping the fescue on #10 will also help hold some golf balls before they roll into the woods. Hole #10 continues to be prepped for sod that will be laid early next week. We have decided to go with a different variety of bermudagrass that we hope will transition from dormancy with little/no setbacks. After the sod is laid please abide by the signs and rope/stakes directing golfers to the cart path in order for the sod to tack down as quick as possible. Thanks for your patience and understanding and we look forward to seeing you out on the course.
