If they brought in Rees Jones to fix up La Costa, they could keep the tournament. They might even land a US Open and help the USGA by providing another solid west coast site.
Kidding...
Anyway, how many other courses on tour are basically intact from 40-50 years ago like La Costa? I know there are a few, but not too many. La Costa is one of those, and it is kind of ordinary by tour standards. Just for fun, how would anyone here modify La Costa if you were hired to do the job?
Regarding the wet conditions: La Costa is in the bottom of a steep valley (note the homes high on the hills around the course), and it's across the street from a huge lagoon.
Also most people probably see La Costa's creek and think it's tiny, but it's actually one of the larger conduits of water I've seen in the city. Just for comparison, the San Diego River is so small that it's not on maps, and I can jump over it. San Diego is not a good place for people who love rivers.
Anyway, my point is that La Costa is predestined to be extra-wet when it rains. And this whole post is a bit of a ramble, but hopefully a worthwile one.
