See third subhead. It's possible the Newsmax source also has it wrong, and it should be associated with the Florida Av break. If that is indeed the case, then all right, we'll add that to the info pile.
Regarding Executive Order, it does appear there is a disagreement there, and I appreciate your providing the link. I'll go back and look some more at where I got that and get back to you.
Regarding Federal assistance--I am noting changes occurring to stuff coming out of Louisiana. FEMA, for example, has a 27th August declaration, which must be made pursuant to a request from a state--in this case, Louisiana. The Louisiana request is dated August 28, at least the one on their website, which is interesting. A previous post here notes that it seems LA made an error in itemizing which parishes to include and "cleaned it up" after the FEMA declaration "missed" parishes. But, having lived in Louisiana, and knowing that a full third of the people in that state live in the four "missed" parishes, I am hard pressed to believe the folks in Baton Rouge, an 80-minute drive up the Interstate when it's open, were that stupid to miss that area. So, let's just say I am regarding anything eminating from the Louisiana's governor's office with extreme skepticism right now.
Another huge wave came across Lake Pontchartrain in the north. It sent a steel barge ramming through the Industrial Canal, a major shipping artery that cuts north to south through the city, possibly creating a breach that grew to 500 feet, letting water pour into nearby neighborhoods of the city's Ninth Ward.The barge's remains were found lying on the bottom of the gap. An early eyewitness reported seeing the barge smash through the levee. His report was never followed up by the media.

That article doesn't contain the string "17" so is not a good cite for the proposition that a barge was involved in the 17th Street canal.
You recent post is the first that I have seen mention a Florida Av break. My impression is that a total of 5 breaches occurred, and those were confined to the London Street Canal, Industrial Canal, and 17th Street Canal.
