Patrick,
Was that after Hurricane Wilma? I remember seeing photos of the damage to Palm Beach's par 3 course, which sits on both the Atlantic and on Lake Worth.
It's funny you write that. Something clicked in my mind after writing about 17 green and I remembered the 1928 Okeechobee Hurricane, a Category 4 storm landfalling between Jupiter and Boca Raton that killed 2,500 people, mainly in and around Belle Glade. The landfall date was September 16, 1928 and it pushed a surge of 11 feet onto Palm Beach.
Here are a few pics:
I doubt the timing of that storm explains the bunkers on 17.
Here's where it gets interesting. If a storm, a tropical storm at least, is the reason then another possibility is a hurricane landfalling from the ESE on Sept 4, 1933, with 130mph winds.
If hurricanecity.com is to be believed, the next tropical storm to landfall in the Palm Beach area did not occur until 1945 -- that too was a 130mph Category 4 monster. And then:
* Sept 17, 1947, 130mph
* Oct 12, 1947, 85mph
* Sept 22, 1948, 85mph
* Aug 26, 1949, 150mph (meter blew away)
* Oct 18, 1950, 90mph ("causing heavy beach erosion")
A few points:
1) If 17 bunker top lines lost waviness due to a tropical storm, the pictures either date to 1928 or to 1933-4, mostly likely the latter. When did construction begin?
2) Never mind WWII neglect, the super-cycle in the post-war period could alone have left the course in a state of disrepair -- in fact, any one of the major storms could have. In Palm Beach the two 1947 storms blew away half the Bath & Tennis Club and led to the creation of So Fla Water Mgt District.
3) More pure speculation unsupported by any direct evidence: at first it seems foolhardy to move 18 tee and green
towards the ocean, after such repeated battering, but to your point: towards the ocean is up the dune and that's higher ground. (Hmm, was repeated storm-caused flooding a contributing factor in 3 green being moved farther up the western dune?)
