Golf Course Maintenance Weekly Monday 2/1/16

We received just over a half of inch of rain last week here at GBGC so I wasn't really paying much attention of what was going on with Folsom Reservoir (FR). I customarily check the reservoir levels every Monday morning as a ritual of sorts and was shocked to see how much it came up last week. It came up 80,525 acre ft. in a week crossing last years level and crossing the Normal level for this time of the year. However it is the only reservoir that is above normal on the State Department of Water Resource's map of Major CA reservoirs. 

On this chart FR is the only CA reservoir
at normal

The weather station measured 0.56" of rain last week bringing our annual rain year total to 10.35" behind a 24" normal by 13.85". We did get some dry weather last week and were able to let the carts off cart paths for the first time in awhile only to have to restrict them again after weekend storm that lingered through Sunday AM. Dry weather forecasted for the week so we will be able to let carts off the path by Tuesday.

What a difference a week makes. FR surpassed last years level and went above normal

Besides mowing the golf course this week since it still will be dry, we will be trimming sand traps along with miscellaneous weedeating and edging cart paths. Trimming sand traps and associated weedeating takes the GCM staff between 80 and 100 man hours depending how we deploy the labor. As in most routine maintenance tasks we are much more productive if we put a  several maintenance staff on the task at a time as well as getting them started first thing in the morning. This job really slows down when we are caught by players which puts a premium on staying ahead of the crowd. Today, (Monday) we don't have a tournament so we deployed 5 GCM guys to get a big jump start. 

Edging Bunkers

The process includes weedeating the edges and banks followed by blowing the created clippings and debris out of the bunker. Next we rake the bunker and check sand depths on the faces. We target one to two inches of sand on the steep bunker faces as we want golf balls that hit in these areas to move down to the bottom of the bunker. That's our intent. It doesn't always work out that way as I am sure everyone has found out on a occasion or two. 

Blowing out the debris

Along with sand trap trimming we made a light application of sand topdressing to the greens this morning and will continue pruning near #17. That's our plan, any major changes I'll let you know.

Thanks

Golf Course Maintenance Weekly Monday January 25 2016

Granite Bay Golf Club is starting off 2016 with a lot of changes even in golf course maintenance although ours are not as dramatic as in the clubhouse and golf shop. Our changes have to do with communicating on a much more consistent basis what our plan's and processes are for the course. I originally set up this online course update to do just that and it evolved into more of a monthly or bi-monthly article on what was done on the course rather than explaining what is happening in the now. Interested Members can get e-mail updates by submitting a e-mail address in the top right hand corner and you will be notified when an update has been posted. My goal is to send out short and sweet weekly updates including pertinent information and of course pictures. 

Current level of FR as of 1/27/16.  As you can see the reservoir is
still below its level at this time last year but should eclipse that mark
in early February.  The drought buster news is snow pack in the
Sierras over 100% of normal for this time of year.

Last week was a wet one. Rainfall measured 2.68" from 1/18/16 through 1/24/16. Total rain so far in January was 5.10" Only two other January's exceeded this  amount at GBGC since 2005. YTD rain season (October-September) accumulation 9.79". Greens remained firm in part due to a light topdressing we applied last week on Thursday ahead of rain on Friday. We have found that light top dressing the greens this winter ahead of a rain event works out well as the rainfall drives the sand into the turf canopy. Since it was so wet last week we were able to shift most of our labor resources into pruning and a re sodding of the wedding ceremony area. With some dry days this week we were able to get out on the course and mow along with allowing carts to leave the path.

Recent pruning efforts at the #15 & #16 bridge. 

Additionally this week we started a irrigation project along the cart path on #18. If you recall previous summers, turf conditions along this path can become marginal. These supplemental irrigation heads will change this situation for this upcoming summer and beyond. In addition  to starting this irrigation project we kept a crew working on the pruning we started  in the #14 green, #15 tee, #16 green, #17 tee area. We hope to finish the pruning in this area by next week and then move these pruning efforts to the fence line along Roseville Parkway starting in the area behind the restroom on #5.

2015 in Review

The approaching year end gives us  an opportunity to reflect on the past years successes as well as setbacks and as most years Granite Bay Golf Club can point to some of each. The historic continuing drought was a big part of the golf course maintenance story in 2015, and continues to be the defining issue of the season as we approach years end however not the only thing to look back on.

Weekly light topdressing is something we committed to
in 2015 and believe contributed to a more consistent
putting surface throughout the year.

2015 Drought

In April 2015 after 4 years of drought which included one of the the driest years, the warmest year & the year with the lowest measured accumulation of snow, Governor Jerry Brown issued an executive order directing the State Water Resources Control Board (SWRCB) to impose restrictions to achieve a statewide 25% reduction in potable urban water usage through February 28, 2016.

The executive order (EOB-29-15) stated “The Water Board shall impose restrictions to require that commercial, industrial, and institutional properties, such as campuses, golf courses, and cemeteries, immediately implement water efficiency measures to reduce potable water usage in an amount consistent with the reduction targets mandated by Directive 2 of this executive order”. Responding to the Governors Executive Order the SWRCB adopted a conservation regulation which placed each urban water supplier into one of eight tiers which are assigned a conservation standard, ranging between 4% and 36%.

Current conditions of Folsom Reservoir is pretty bleak, however we still
have the winter ahead of us with unanimous El Nino predictions.

Granite Bay resides in the San Juan Water District (SJWD) service area and was assigned the highest conservation level of 36%  based on residential gallons per capita per day (R-RGPCD). By the end of the year we achieved the 36% reduction from 2013 use in raw water purchased for golf course irrigation and through November our combined potable water meters on the property had reduced 40% from 2013.

Even with the unanimous prognostication's from weather forecasters of a strong El Nino winter to hit the west coast, many doubt it will be enough to end this historic drought. Through December the States reservoirs are filling and more importantly the mountains have above average snow however these reservoirs were so depleted over the last four years that it will take allot of El Nino to fully recover. My suspicion is we are in for another year of mandated reductions which could lead into a new normal particularly with another CA State government mandate "20 X 2020" which requires a 20% reduction from all Californians by the year 2020.

Non of the States Reservoir's are looking reallygood at this point of the season.

The Good News is the Snow Accumulation. 

2015 Early Winter and Spring Flash Flood

Despite another year of below average rainfall we did experience some drastic weather that changed the landscape here at Granite Bay. On December 12 2014 we experienced a strong storm that brought 4" of rain in two days. A good portion of that rain fell in the early evening of December 12th causing Linda Creek to overflow it's banks and move a large rock that was stabilizing the creek bank near the bridge abutment on #14. The rock moved off the bank down into the creek exposing soil directly near the bridge abutment to further erosion in subsequent storms. 

As it turned out we didn't get any more substantial rainfall from January through April 2015 contributing to the continuing Statewide drought. One thing lead to another and we didn't get to properly stabilizing the exposed soil near the bridge abutment with the exception of some temporary old concrete rip rap to protect from El Nino this winter. Our permanent plan is to remove the temporary rip rap once the El Nino threat has past and stabilize the entire creek bank with rock on top and in front of a geo-textile barrier to prevent further erosion issues.

Another destructive weather event occurred in May where a unexpected flash flood went over the course creating a substantial mess and damage. This is the storm that collapsed the library patio cover and washed out our walnut shell areas like we have never experienced in 20 years. We received just under 3" of rain and hail, 2" of which came down in one hour. That's the definition of a frog strangler.

Summer 2015 Turf Loss and Fall Recovery

Because of the drought and its associated restrictions we decided against aggressive core aerification of green surrounds and fairways in both the fall of 2014 and spring of 2015 because of the amount of irrigation water it takes to recover from such an event. This calculated omission along with irrigation reductions and a warmer summer helped produce some stressed turf areas throughout the course that we needed to recover from in the fall.

Typical Granite Bay turf stress in the summer.

Our corporate Agronomist's visited Granite Bay during this stressful period and concluded if we are going to continue to try to hold onto cool season turf  from July through September we would need to start applying more protection to fairways and green surrounds for disease which is commonly  part of the stress equation in the summer months. This would require more resources which we we able to secure in the way of seed for recovery this past fall and disease prevention products for 2016.

Irrigation Controller Installation in 2015

We completed Phase I of our irrigation controller replacement in 2015 as scheduled. Phase II is slated to be funded in 2016 and we are trying to get it funded early so we can complete the installation process in the first part of the year. Replacing these controllers will benefit us more then just replacing 20 year old electronics. Replacement will facilitate single irrigation head irrigation control to a much higher degree then we currently have. Before we started this project we had 40% single head coverage. Upon completion we will achieve 90% single head coverage. The main advantage to single head coverage is we can control the amount of water each individual sprinkler head applies helping with both dry and wet spots in the summer along with producing                                                                   water savings.

Miscellaneous Traffic Control Changes 2015

We did adopt some different golf cart traffic control measures in 2015 that we hope moving forward will have a positive effect turf grass conditions particularly in the summer months. First we plan to continue to rope off  different holes in the summer to proactively protect the turf from the damages of cart traffic. In the past we roped along walnut shell lines allowing concentrated cart traffic under the Oak Trees inhabiting the shell areas. This added compaction combined with drought was not the best thing for our Oak trees as outlined in a course update entitled Golf Cart Traffic & Native Oaks. Therefore when we rope off a hole in the future we will no longer follow the walnut shell lines but the cart path to eliminate that concentrated compaction. I hope we all agree a few more steps is worth it to do all we can to protect these assets.

Another traffic control measure we put in place late in 2015 was the use of small white and green stake delineating where to enter and exit the golf hole with your golf cart. We have observed many members adhering to the protocol and this will make a difference in managing the wear and tear of cart traffic. Look for the three small white and green stakes at the beginning of the hole and the same trio closer to the green on and enter from the cart path on the first set and exit to the cart path on the second set. Golf course maintenance will move those stakes throughout the week to distribute wear. Simple as that.

2015 In Conclusion

From the entire Golf Course Maintenance Staff we would like to thank you the Granite Bay Members for your support of our efforts in 2015 and throughout the years. The dynamic nature of maintaining a living breathing "game board" presents unique challenges along with opportunities to exceed expectations. That is our goal, and we appreciate your encouragement and recognition of those efforts.

Golf Cart Traffic & Native Oaks

We recently had a consultation with a Certified Arborist regarding the creation of a preservation plan for the native oaks on the property. I'm certain we all agree that the native oaks at GBGC are a crucial part of the course's aesthetics's and design concept and a strategic preservation and replacement plan is a prudent action.

History

The original golf property was considered a Blue Oak (quercus douglasii) woodland as Blue Oaks were, and still are the dominant native species. The secondary species often associated with a Blue Oak woodland are Interior Live Oaks (quercus wislizeni). There were  approximately 4400 oaks on the property before construction and approximately 1100 removed during construction. The original design and course in 2014 did not include walnut shell areas and had wall to wall irrigated turf throughout the property. Areas such as #6 & #7 and large area between #1, #11 & #10 are good examples of  areas of solid turf in  the golf courses original state. 

After losing over a dozen or more large Blue Oaks very early on in 2004, the decision was made to remove irrigation and add walnut shell in many of the strategic areas. This is because  summer irrigation, particularly near the trunk of some Oak trees keeps the root crown, which is directly beneath the trunk, wet and causes a crown rot that is a death sentence for many California Native Oaks. This required the removal of turf and re-triangulation of the irrigation system then spreading the walnut shells. Oak trees can take and actually use summer water on the periphery or drip line but when irrigated with the consistently necessary for turf near the trunk, native Blue Oaks commonly struggle then fail. 

The removal of irrigation from the Oak trees root crown area saved the trees from crown rot but  created the unintended consequence of excessive heat near the feeder root system  inside of the drip line. In a Blue Oak Woodland's natural state there would be several inches of mulch consisting of decomposing grass and leaves. This mulch not only helped the soil retain moisture from winter rains, but also insulated the the feeder roots from the summer heat. According to the arborist we consulted, this heat in the summer is another major stress to native Oak trees that had been accustomed to this thick layer of mulch.

Another stress to these Oak trees according to the arborist is the compaction we are creating with golf cart traffic,  particularly on the holes we have roped off like #10 & #1. Allowing the traffic to concentrate in these walnut shell areas could have a deleterious compacting effect on the root system of these existing Blue Oaks which are already suffering from heat and from drought the past few year's.

We don't have the option of installing a thick layer of mulch in these areas as we need to provide a lie in which to play golf. We certainly don't have any control over how much rain we are going to receive in any giver year although if this drought continues I can see us setting up  supplemental irrigation for the trees. We do however have control over cart traffic in these areas. Therefore when we set up traffic control on a hole in the future, we will set the control rope up on the cart path edge rather then the walnut shell edge. Understandably this will require a few more steps on roped off holes but we must do what we can to protect our trees.

Moving Forward

We did get some California Native Trees planted two years ago to replace trees that we lost along with proactively planting for trees that we suspect will lose in the future. A course update from a few years back entitled Tree Planting & Restoration detailed our strategy of replacing trees. In the future I am going to propose we get a batch of trees annually in our capitol and proactively plant more trees that we suspect will need replacement in the future. Obviously if we get them planted now they will be closer to maturity when we have to take the tree down that we have designated as needing replacement someday.

plantings need to remain somewhat remote from

2015 Fall Aeration

September 23rd was the  2015 Fall Equinox, the day I circle on my calender as soon as summer starts in late June. The fall or autumnal equinox is special because it marks the time when cool season turf can really start to recover and thrive as opposed to the 12 weeks or  specifically 88 days of summer. And because Granite Bay Golf Club is predominately a cool season turf golf course it is the time that we recover from our summer turf setbacks.

It also marks the time of the year that we start to aerify the golf course which can help with the aforementioned recovery process. We have front nine, back nine alternating closures starting on Tuesday, October 6 2015. 

2015 Fall Aerification Schedule

• Tuesday 10/6/15         Course Closed   Core Aerify Putting Surfaces
• Wednesday 10/7/15    F9 Open  Aerify / Seed B9 Fairway / Rough
• Thursday 10/8/15       B9 Open  Aerify / Seed F9 Fairway / Rough
• Tuesday 10/13/15       B9 Open  Continue  Aerify / Seed F9 Fairway / Rough
• Wednesday 10/14/15  F9 Open  Continue  Aerify / Seed B9 Fairway / Rough

Aerificarion Process Fall 2015

Four years of drought and Granite Bays total reliance on  Folsom Reservoir as it's golf course irrigation source has taken it toll on many of the turfgrass areas throughout the course. Mandatory reductions of 25% in 2014 and 36% in 2015  along with the lack of deep soaking rain for trees and turf have left the soils dry. 

We've managed these reductions avoiding wholesale loss of turf but not without our  issues.  As much as the golf course needs an aggressive core aeration right now we have to be careful because this drought is not over. We still have a mandate to reach a 36% conservation from a 2013 benchmark and aggressively opening the golf course up with aeration would require more water for recovery then we currently have.

Therefore our plan is to core aerate greens and spot aerate fairways and rough. We will be rolling the dice and seeding all of the areas that have thinned out this summer and hope that the forecasted 95% chance of a strong El Nino event will soak and establish the seed throughout the winter. Hopefully this forecasted event will at minimum ease the drought restrictions in 2016 at which time we will aggressively core aerate the entire property in the spring. Hope is not a strategy but the scientific forecast does give me some. Time will tell.

New Location for Bunker Rake Placement

At our most recent Golf Committee meeting the age old question of  where sand traps rakes should be placed was discussed. In  the USGA article, Experts Explain: Bunker Rake Placement, the topic is broken down because as the article explains "There is no rule on bunker rake placement". 

The 2012 article goes on to explain that "The USGA recommends placing rakes outside of the bunker and parallel to the line of play, preferably along the outer edge of the bunker so that it will reduce the overall chance of it coming into play while eliminating its influence of a ball within a hazard"

After a reflective debate the committee agreed with the USGA recommendation's so golf course maintenance placed the rakes outside of the bunkers on the morning of 9/30/15. Driving the course the same afternoon afternoon confirmed this change will need some getting used too as many rakes were placed back in the bunkers. Unintended consequences such as more run over rakes and golf course maintenance issues are inevitable and anticipated but for now Granite Bay is going to "Rakes Out".
