The Siren Board

I've been particularly interested in going into random cities via. Google earth and looking for CD sirens or remains of them. I was recently looking in Mardi Gras land, or New Orleans to everyone else, and ran across two former siren sites:

Memphis & Harrison: This is almost certainly an old Model 2 site. I genuinely think that the basic concept of a thunderbolt here is incredibly far fetched and probably would've broken the pole, for obvious reasons:

City Hall: I have heard this is a former thunderbolt site according to some rumours and according to some old pictures posted here (I believe by me or Eric G.) of two guys checking out a Thunderbolt. I will post a link to the pictures if I can find them.

Elysian Fields & Claiborne: This is the thunderbolt site Adam P. posted about a long time ago. Complete with the world's crustiest RCM-1 or us to feast our eyes upon:

My question is: is there any more left of their old sirens, or are just setups like the two mentioned intersections all that remain? Giving that Katrina happened 10 years ago, that surely would've wiped away a good chunk of the 5 thunderbolts and 80 something Model 2s the city once had. However, I feel like somewhere there is a siren left. I don't really know why though, maybe just another pipe dream of mine. Incidentally, would anyone else here happen to know about any other CD sirens locations in the Big Easy?

Edit: Pictures mentioned in the "City Hall" bit are in this thread, 5th post down:

Only problem is, none of the pictures from the Vintage Thunderbolt Pictures thread work.

There was definitely a Thunderbolt on top of city hall, here's a few pictures of it:

Siren is on city hall (White Building) on the lower right, look on the upper left corner of city hall, you can definitely make out a yellow Thunderbolt horn.

Here's that same siren from up on the roof.



Also, there appears to be a ''brand new'' Display Model 2(T)shroud inside the New Orleans Civil Defense Bunker, it's in the very beginning of this video:

I'm going to add this, I think I found a former Model 2 site on the south side of the intersection at Paris and Mirabeau. To me it looks like Memphis and Harrison, just missing the electrical box and crossarm that held the siren.
