If your interested in the agronomy of the renovation I urge you to use the link to the Valencia Golf Club site. It has monthly updates on the renovation also that are very interesting with pictures.
I started playing this course when it was public in 1979 along with its little brother the executive
course also designed by RTJ called Vista Valencia, the locals called them big V and little V.
I enjoyed the RTJ design because you couldn't just play to the middle of the greens, in order to get a fairly flat putt at a birdie you had to hit it near the portion of the green where the pin was placed and each green had at least four different miniature green areas.
There was an interesting history about it going private in the 90's I believe. A Japanese conglomerate bought the course for around $6 mil along with the motel next door. At that time golf memberships in Japan went for millions so this conglomerate bought the American course and made it private with minimal local members to pay for maintenance and would fly over about 100 Japanese members and shut down the course for a month to only those Japanese members several times a year and put them up at the motel next door. They even added a sushi restaurant to the motel for their guests. Most of the year you could drive by the course and it was nearly empty.
