Santa Anna bermudagrass is becoming popular in that region. Mr. Nicklaus commented on it a few weeks ago when I had the honor of speaking with him at Old Marsh, but Sherwoods turf didn't come up, only trees. Frontier Golf is doing the construction.
In an effort to conserve water, and years of overseedig, all logic leads me to think Bermuda roughs and maybe fairways? LACC is all bermudagrass
