The suggestion was to remove the levees south of Braithewaite on the east bank and just below Belle Chasse on the west bank to allow a natural river flow and land building. My point was that although one of the least populated parishes in the state, there is still quite a bit of industry in Plaquemines Parish.

When you travel south on Belle Chasse Hwy (LA 23) there's the river levee on your left and the "back" hurricane protection levee on your right. They're within sight of each other in some places. Presumably they're there for a reason and if removed, I'd think the whole place would periodically be under water.


I was the one that suggested that.

And your thoughts about industry are EXACTLY the point i was trying to make. Sacrificing Plaquemines below Belle Chasse would insanely costly given all the industry down there. The cost would be pretty much impossible. And that's probably the CHEAPEST (lol) place to do something like that. Moving upriver, you are talking about hundreds of thousands of people, and upriver from there, the huge industrial zone from St. Charles Parish up to Baton Rouge.

So the suggestion made by others that the cost of protecting is greater than the cost of relocation is simply silly.

Should start buying land in the flood plain below orcs. Eventually going to lose it and better to start getting some of the damage purchased now vs later

This definitely is setting up as a top 5 flood.


Dammit that means no turkey hunting at my hunting camp on the unprotected side of the levee.

Yes, the COE needs to be ready to open the Morganza and BC spillways to drop the river because the snow melt has not even started yet.

Anybody who doesn't think something is changing with the river (and/or the weather), just needs to look at the frequency of the spillway being opened as a point of reference.

This will be the 13th time it's been opened since it was completed in 1931. Six of those openings are in the past 12 years, and this will be the third opening in four years. There was a stretch between '73 and '83 when it was opened four times, but that's been the only other time that's been nearly as busy as it's been lately.

It could be we have 10 or 12 years of wet weather every 40 or 50 years. It could be the river bottom is rising. It could also all be my imagination.

In the long run it would be cheaper to move everyone living down there out and have all industry down there make adjustments for high water then what the long term cost of battling coastal erosion is. Add to that we will still probably loose anyway.

Definitely a complicated situation. Would be interesting to see a academic study on the 50 year costs of each. The affects would probably be crazy far reaching.

Of course there is always the possibility of continuing with the with the status quo and disaster still happening. As someone else said, minor earth quake + high river levels.

If we'll probably lose anyway, how does spending billions to buyout and relocate about 1/2 of the state's population make more sense than just continueing with the levee systemm and delaying the inevitable?

Everybody on the west side of Highland Road better have lots of flood insurance.

It's obvious if you are willing to see it.

Changing the weather will be even trickier than changing the river, with the same risk of unintended consequences.

It seems like the first issue to address would be the shoaling downstream of the ORCS. Next would be engineering fiscally and technologically viable sediment diversions on a large scale. Both easier said than done.
