Mark -
I played the OC Ocean 2 days ago.
The OC Ocean Course has had more alternations, reconfigurations and renovations over the past 25 years than Joan Rivers! There are perhaps 2 or 3 holes still intact and in play from 25 years ago.
There are several aerial photos of both courses taken over the last 60+ years on the wall in the men's locker room that show the "evolution" of the Ocean Course. Remember, less than 15 years ago, there were 4 holes for the Ocean Course built west of Skyline Boulevard. They lasted 2 or 3 years before a landslide took them out of play.
The terrain on a handful of holes is quite hilly.
The most recent work on the course (a total renovation) was done by Weiskopf 8-10 years ago. He retained most of the routing of the holes on the front nine, but the back nine is pretty much brand new. One of the holes on the back nine was just altered.
The greens and bunkers on the Ocean are noticeably larger than on the Lake, although there are 2 holes on the Ocean that have no greenside bunkers at all.
I will be interested to see how the scores on the two courses compare in the US Am qualifier.
