Not sure what Mr. Kay's level of involvement is in the ongoing work at the club. Most of it is quarterbacked by the Greens Chairman (and 10+ time Seawane Club Champion) Edward Nusblatt.
A decent amount of the changes are pretty subtle and probably don't require Mr. Kay's work--for example, the sod-faced bunker fronting the tenth green has been reworked over the past year to change the angle of the face from about 60 degrees to basically 90 degrees. It's such a small change you probably wouldn't even notice it from one season to the next...but it changes the playing characteristics of the hole dramatically from the green all the way back to the tee.
In the past, that front bunker was the miss--even with the sod wall. With the angle the wall used to be at, players who missed in the bunker short could still recover and easily make par from almost anywhere in the bunker. Now, with the wall going almost straight up, 50%+ of shots missed in the short bunker require either a pitch out sideways, a blast backwards or a Sergio (2000 Open at St. Andrews) style putt to an area of the bunker that's a bit more playable.
This changes not only the recovery plays from the bunker, but also the strategy a player must take in the fairway and off the tee. From the fairway, the new rule is "when it doubt, take more club" to avoid the bunker. In the past, it used to be "take less club." All the sudden, just from this small change, the swale beyond the shallow putting surface looks like a great miss. Back on the tee, players are less inclined to take fairway metals and drivers because the cost of missing the fairway at #10 has increased significantly. From the rough, 6 is a very plausible score even from inside 120 yards on a hole that measures less than 360 yards.
I could easily argue that the hole is now one of the best non-drivable short four-pars around. I'll snap and post some pictures of it if you'd like. I think it was a genius little change and I'm pretty sure Mr. Nusblatt and our excellent Super (Brian Benedict) deserve all the credit for it. But I'm happy to check on the details for you next time I head out there.
They're also building what looks like 700 new tee boxes on the 11th hole. It's really only four new ones I think, but the suddenness (is that a word?) of it makes it seem like more. This is a much more extensive project and might have required some assistance from Mr. Kay. Not sure though. Will look into it for you as well.
There are a bunch of other little changes here and there as well. The course also lost what I've been told is anywhere between 50-150 trees thanks to storms we had in March. I also hear some scuttlebutt about changes to the third hole (pictured above). There is talk of making the entire green complex and the tee at #4 an "island." Not sure about this though--could just be rumor. If this is true, I'd imagine it might require more than just the work of Mr. Benedict and Mr. Nusblatt.
