I must of read a more detailed article. It said the course would be about 6 - 8 m and the CH would be about 16-18 m. They are also doing a bunch of related stuff like shotlink kiosks throughtout the course, and expanded practice amenities with PGA tour academy. It said that they are going to plate each fairway with sand, removing the existing organic topsoil. Add subaerification and drainage to the greens.
The CH is to include a Walk of Fame entrance. Enhanced spectator view will be added at holes 16, 17 and 18. Whatever that entails.
It does say that Pete Dye is overseeing the course work.
