Golf Green Design

To me, at least, green design makes the difference between good and great golf courses. From big to small, flat to undulating, round to square (ish), heavily bunkered or no bunkers, they should all get the golfer thinking about the approach shot they are about to hit.

Drawn and designed at a 1:200 scale because of their complexity, they are accountable for a big chunk of time in the design process. One project for example could easily have 40 or more greens (including practice facilities) to design, each a different size and shape with different borrows to fit the golf hole that is laid out before it.

Every green design is painstakingly drawn with a high degree of detail, up to 6 contours per meter. The drawn design is not by any means set in stone, more often than not the Golf Course Architect will tweak (sometimes more than tweak!) slopes, humps and bumps when they are on site.

One thing that must be considered as a part of the green design process is creating areas that are flat enough to be ‘pinned’. There should be at least 5 suitable areas on a green for the pin, if, for nothing else, to cover the 4 days of a big tournament. To meet European Tour standards for example a pinnable area will generally have a gradient of less than 2%.

Along with Pin positions another aspect to be considered is the type of grass being used on the putting surface, the mowing height and potential Stimp reading as this will have an impact on the slopes and shaping. Generally Greens will be cut between 3-5mm depending on the time of year and during the summer they may be cut twice daily to keep the greens fast. The Stimp meter is a device that allows the Golf Club to gauge the speed of their greens. For Championship Golf they are normally a minimum of 10 feet on the Stimp. 12 feet is usually as fast as a professional golfer would see, Augusta’s Stimp however can run at 13 feet.

Now for some very basic construction information. Typically European Golf Design build greens to conform with the USGA recommendations for greens construction. Starting from the bottom upwards; The first job is to shape the green subgrade so that the contours in the subgrade reflect those of the finished shaping. A series of drainage lines are trenched into the subgrade, these will contain the perforated drainage pipe and be backfilled with washed gravel. Above this is a 100mm layer of the same washed gravel. Finally on top of this sits the seedbed mix which is a 300mm mixture of sand and organic matter. Occasionally a plastic membrane is installed around the green perimeter which is used as a barrier between the subsoil green profile edge and the gravel blanket and rootzone mixture.

One aspect I have not covered is grass seed. There will be a blog to come on this, so to find out more on Bent or Bermuda, Pencross or Penneagle watch this space!

  • Herringbone drainage which forms the lower layer of the green construction. Perforated plastic pipes in the herringbone trenches to facilitate drainage of water. Around the green perimeter is a plastic interface membrane used as a barrier between the subsoil green profile edge and the gravel blanket and rootzone mixture.

  • Spreading the washed gravel layer across the green area which forms a drainage base for the seedbed mixture above. The washed gravel layer is usually 100mm thick. The gravel is smoothed out using rakes. Photo taken at The Dutch in The Netherlands.
  • The seedbed mixture forms the top layer of the green construction. Typically 300mm thick and a mixture of sand and organic matter. Photo taken at Navarino Dunes in Greece.

Football Mugs and Football Thugs

Football is well represented at EGD; it is often at the heart of a heated discussion especially on a Monday morning.

Starting in the back of the office we have Gary, a Glasgow Rangers fan, I don’t have much to say about Rangers apart from Gary could probably get in that team at the moment. It also helps getting tickets when your uncle is the Chairman!!

Robin and Dave are Spurs Fans. One would be too many. Sleeping Giants? I think they are in a coma. We mustn’t also forget Rob’s first love Halifax Town who languish in the Unibond league.

The Man Utd Mug belongs to Matt, he doesn’t like the diving that has come into the modern game and hates Ronaldo’s greasy hair, he was glad to see the back of him. His Favourite Utd player? I would say Wayne Rooney, of course, the toffees taught him everything that he knows.

Jeremy is a Gooner, he has not forked out for a mug though. Maybe he is not very proud. Or is it us? Maybe we haven’t seen it like Mr Wenger.

Sarah is a part time Liverpool fan, when they lose (quite often this season) she cheers on Fulham. I think she fits in better with the fans in South West London rather than the Merseysiders. She does own a pair of highly one sided Liverpool goggles though.

Shara, as far as I know the only team she supports is the one that her sons James and Sam play in. She is probably the most sensible of all of us.

Ross – he is a Hammer, currently they are in the relegation zone, the team that put them there last week with a win at Upton Park? Everton , that happens to be my team. The Pride of Merseyside.

Stan also likes football, his favourite team? The Chicago Bears. Huh.


Come on you Toffees!

An Afternoon Out

Yesterday Gary, Dave, Rob and Myself were lucky enough to play the Old Course at Sunningdale. After throwing the balls up on the first tee Dave and I were paired together (again). This gave us the chance of some revenge after our defeat at Sunningdale Ladies. Dave started very well and we quickly found ourselves up in the match. We reached the turn 2 ahead. Robin and Gary were still upbeat though after I had given them 2 ‘ooslam’ bits after some sloppy putting on the par 3’s.

After I won a couple of bits back at 13 and 14 Dave and I found ourselves 3 up with 4 to play. However, Robin then made a good 3 at the 15th to keep the match going, I then went missing for the last 3 holes and Dave couldn’t quite hang on despite a great double sandy par at 17, the match ending in a half after some impressive golf from Gary.

I quite like writing these reports, I can skim over a match and not mention the duffs and tops that I hit, the snap hooks that Rob hit and the big push slices that Dave and Gary hit…. oops I just did… sorry chaps!

I should also mention that the course was in great condition, the new bunkering looked great and fits in really well. It was a pleasure to play. A big thanks goes to our Director and Sunningdale member Michael King for organising the game for us. 

Golf in Gullane

I have just arrived back in the office from a long weekend in Scotland. I visited Gullane in East Lothian for a couple of rounds with some of my family, the weather prohibited any more than that, I have never seen so much rain in September, and when it wasn’t raining, I think the term ‘blowing a hoolie’ sums it up. It was our first long drive with the new dog, who behaved much better than Alaina in the car, sleeping most the time.

Alaina and I lost narrowly to my Dad and Brother on the first day on Gullane number 3. A short but not easy course, the pictures not really doing the wind justice. We then got another game in on Gullane number 2, another nice links course with some great views over the Firth of Forth and into Fife. Luckily, I did not lose the second game, My Brothers and Dads nerves getting the better of them.

There is some other news from the weekend, Alaina and I are getting Married. Against the odds she said yes to my question on Friday night. The Picture of her and Mac(the dog) was a few minutes before I asked her……..

A Day at Wembley

As a toffee I have been starved of trips to Wembley for many years. 1995 was the last time the blue half of Merseyside made the trip. Sunday saw a repeat of that years final.

The day got off to a good start, I managed to convince Alaina (my girlfriend) that a pre game trip to Ikea wasn’t a good idea. After being dropped off at the ground, my brother, his colleagues and I headed in for some food and drink. A few glasses and bets later (most of which were on a first goal scorer!) we headed to our seats for Kick Off. The wine helped with the nerves and seeing a under strength Man Utd team I felt quietly confident. The fans were as loud as I have experienced, my ears are still ringing two days later.

The first half was tight with chances few and far between. Getting to half time with it goalless I felt that Everton would not have better opportunity to get to the Final of the FA Cup for many years to come. The blues started well in the 2nd half and the fans were making themselves heard. Utd slowly took control after 60 minutes or so, Vidic and Ferdinand winning the aerial battle with Evertons 6’3” (6’7” including hair) Fellaini, the Reds were looking the more likely to break the deadlock. Mid way through the second half they were denied a clear penalty and I’ve never seen a man more angry than Alex Ferguson at the moment, his face was a new, undiscovered, shade of red.

With it still goalless after 90 minutes the game headed for extra time. Again not much action, but, Cahill was stopped in his tracks when through on goal having been adjudged to have fouled Vidic, another suspect decision from the ref! A few minutes later the final whistle went and penalties were to decide who would play Chelsea in the final. After Cahills rugby conversion my head was in my hands, however, Berbatov and Ferdinand both missed allowing Phil Jagielka to score the winning spot kick. A blue day it was, The red half of the stadium emptied very quickly!

Pic of the Day

Stan Eby returned to Carton House for the 2010 Senior Irish Open. Working with Colin Montgomerie Stan designed the 'Montgomerie Course' which is now rated as one of Ireland's finest. It hosted the Irish Open in 2005 and 2006, the Montgomerie Course is very much reminiscent of a traditional links course featuring rolling fairways, gently undulating greens as well as steep faced deep cavernous bunkers.

What Our Clients Say

How did we do? Did we provide you with the service you were hoping for?

Fantastically. Yes. So much so that you became Marriott's sole course design partner. Perhaps your greatest strength (at least the EGD designers that I worked with) was your willingness to treat the opinions of the client (re design ideas etc) seriously. Never underestimate the value/importance of this.
