Aerification of greens, tees, fairways, and rough have many benefits. Decreased compaction, improved air and gas exchange, thatch removal, and amending the profile are just naming a few. Every golf course is different in terms of climate, grass varieties, soil composition, nutrient levels, and amounts of traffic. This means that no two courses can be managed the same, and for that matter no two greens can be managed exactly the same.
Throughout the growing season we implement many cultural practices to improve turf health and conditioning and more often than not they are directly related. Many golfers know the term aerification and have heard terms such as "needle tinning" or "venting" but may not exactly know how crucial these practices are to keeping healthy, playable turf.
Recently we aerified a green on the north course that was starting to show signs of stress related to compaction of soils and a lack of oxygen. After months of mowing, rolling, and having plenty of golfing traffic on the greens, it's not uncommon to see issues by August. Most superintendents, including myself, use "needle tinning" to poke very small holes in the putting surface therefore allowing air and gas exchange as well as reducing some compaction with very minimal impact to putting. In rare cases it's necessary to use a larger hole to improve conditions and ensure healthy turf through the end of the growing season.
To better explain why it's necessary in some areas and not others, I have included a few photos to show the difference in greens below the surface. Sandy soils will not compact like heavy soils will under the same traffic stresses and therefore will act much differently at the turf level. In addition, a green that is built correctly will allow for the entire profile to hold or release moisture evenly and consistently.

These photos are compliments of member Dave Senator and guest to the club Kathy Fenner who were both able to capture a few great pictures of our nesting eagles. The eagles remain in their nest on 7 West and there are reports that another eaglet has been born and is growing well. As we are stewards of the environment and wildlife, it's great to see such a beautiful bird choosing to make Walnut Creek Country Club it's home!

This spring has been very busy with completing projects and general maintenance of the facility through heavy rains and generally cool weather. Below is a quick recap of a few projects that are wrapping up or have already been completed.
|Future cart path site was stripped of sod|
|Cart path area was excavated|
|Grade stakes with set and string line was put up for cart path edges|
|Crushed concrete based was compacted to a depth of 4" to make a solid surface for the concrete. Fabric lining was also used under the crushed concrete for stability in areas that could hold more moisture in the future|
|Forms and base completed|
|All work was done by in-house staff. 30 yards of concrete were poured and finished over 2 days|
|Grade surrounding thew new path was excavated and worked to match the cart path. Sod was laid as the final touch.|
|All bunker faces were sodded following railroad tie removal|
|Drainage that had failed was dug up on select bunkers on the West course and repaired.|
|Fertilizer storage at the maintenance facility was updated for cleanliness, safety, more room, and ease of inventory. This photo illustrates how fertilizer pallets were previously stored.|
|Updated shelving for fertilizer storage|
|Another lightning shelter base was re-leveled. Previously the bricks were very uneven and needed repair.|
|Solid tine aerication was completed for all 31 greens within a two day window|

Weather is changing and it's that time of year. Winter greens covers will begin to be installed on the North and West nines on Friday, November 25th. Starting Friday, the North and West nines will be closed for the 2016 season. The South course will remain open until further notice.

|This picture shows where an old cart path was on 8 South. After construction this path was no longer in use. Using our mini-excavator, the old asphalt was removed and new soil was graded into this area.|
|The old cart path with new soil graded in and close to being ready for seed. This area will be seeded in the spring of 2017.|
|Patio pavers underneath the lightning shelters were in poor shape.|
|Pavers were removed. As can be seen in this photo, a sufficient base was not used in the past to keep the pavers from moving.|
|A new stone base was installed and compacted and the pavers were laid back in place. Finish grading and sod is the next step to completing this area.|

|Fine fescue natives are being treated for weeds today as part of our fall maintenance program. Cutting down these areas to normal rough height will begin on September 30th which also helps control unwanted weeds as well as dead plant material.|

Course maintenance in July generally includes watering turf, fertilizing, mowing, and other routine items. Repairing a bridge was not planned, and certainly not ideal, but due to our staff size and talented individuals working at WCCC, we were able to handle this project in-house. The culvert pipes under the bridge suffered years of abuse from storm water passing through them. Three concrete drain culverts are connected together underneath the surface to move the water, but one came disconnected causing the cart path to begin sinking around it. Using our mini-x, our staff dug out the old cart path, removed the soil from around the disconnected culvert, re-packed new stone around it for stability, and completed a new bridge installation. Below are a few pictures from the process.
|Cart path sinking around disconnected culvert|
|Space can be seen here where the connection should be tight|
|Stone was compacted all around the pipe for stability|
|New "bridge" was framed and leveled with sand|
|Wire mesh installed for strength and concrete being poured|
|Concrete finished and rebar set for block installation|
|Block being installed on both sides|
|Stone veneer was custom fit piece by piece|
|Thin veneer being applied to the sides|
|Cap pieces added as the final touch|
|New path poured to align properly to the new bridge|

With a very talented staff and supportive membership we have been able to accomplish great things over the last few years both on the golf course and on the surrounding grounds. Recently, Assistant Superintendent Michael Brown was put in charge of a patio building project on the back club lawn. Michael's background in hardscaping lined up perfectly with the new patio build that was proposed. After detailing the scope of the project and budget with materials and labor factored in, it was determined that by doing this project with in-house staff vs. contracting it out, the club was able to save over $20,000. Michael did an outstanding job managing the project and the final product is beautiful. We hope members and their guests enjoy the new patio this year and for many more years to come. Below is an explanation of the process involved with building a patio of this scope, and the detail that goes into it.
|Four different quotes were collected for our bulk patio supplies order. When the order was placed, all materials were delivered at once to minimize delivery costs.|
|Once the materials were on site, excavation began using our mini-excavator. To blend the patio and wall into the hill, almost three feet of soil had to be excavated on the back side where the seating wall would be placed.|
|Mother nature didn't always cooperate and frequent rain during excavation made for a muddy project.|
|When all the excavation was complete, the patio shape was re-marked and flagged. Small tweaks were made at this time to ensure the area was properly graded.|
|6-8" of stone base was added above the soil grade and compacted to provide a firm base for the patio. Doing this minimizes the risk that the patio blocks will ever move.|
|Construction first began with the seating wall that wraps around the back of the patio including the steps. This involved custom cutting some blocks to make the shape needed for our build.|
|Utilizing the wall blocks, steps were built for entering and exiting the patio. It was extremely important at this time to ensure the blocks were set at the proper grade using a laser transit and levels.|
|Once a level, compacted grade was established, the wall went up fairly quickly. All wall blocks are secured together using construction adhesive.|
|Wall blocks were placed all around the exterior of the patio to allow for less carrying of the heavy block to set them in place.|
|Drainage tile was installed behind the wall to move water away from the patio. Geotextile fabric was also used against the back of the seating wall to prevent the movement of soil through the cracks.|
|Geotextile fabric installed along the back of the wall|
|Before pavers could be laid across the whole patio, a contractor was hired to run the main gas line and electric service into place.|
|The patio build didn't come without it's problems! Weather changed and everything froze. This slowed down the build but in the end did not negatively impact it.|
|The patio paver process moved quickly when the staff helping was trained to take over the leveling process.|
|The fire pit was built into the patio over top of the previously placed gas line|
|Step coping was set in place during the installation of LED lights|

|Plumbing of the fire pit was also done by in house staff|
|Finished patio! Great job by all the staff!|
