The plan is to build a new pad on 15, but leave the old pad in place. There are stakes and paint at the new pad location only. The concrete may be there this week. If it is there already, I'd be surprised.
If all goes according to plan, 15 will have two or three pins on the west side of the walk trail, and the trail will be OB. The current 15 pins will go away. 16 tee box will move over near where 15 long pin is, and 16 will play to the current pins, but from the re-located tee. The walk trail will of course be OB for hole 16 as well.
I'm not sure if or when any of this will happen for sure, but that is the plan.
