Love all the comments from those who aren't affected by the diversion. The main problem with S Louisiana is erosion happening because of diversion we should let nature be nature and adjust our lives. If so, coast would be much much more sound and extended
The real, honest, no kidding answer is to remove all the levees on the MS river south of a certain point, maybe say Alliance on the west bank and Carlisle on the east bank. You would basically have to buy out everyone south of that point.
Plus many of the same oystermen and fishermen who don't want the diversion also don't want to be forced to move. And that's the problem, there is no reasonable acceptable alternative to them.

Diverting river water back into the marshes IS as close to letting nature be nature as we can get without scrapping the levees altogether. Throwing rocks, sand, and old christmas trees onto the barrier islands ain't gonna cut it.

Not to mention the impact to the shipping and ONG infrastructure that is currently situated based on the current mouth of the river.

Maybe Louisiana can use the diversion money for both a new LSU area and a new River Center area?
Who needs a coastline when we can have a new LSU arena!
The idiots tanking this project probably don't understand the differences between subsidence and erosion and what's actually causing the issues we have.

You do realize that by doing so would completely bring a large swath of the economy to a standstill once the River shoaled in from the sediment. Killing navigation which transports essential goods is not a realistic approach to ecosystem restoration.

Correct. Targeted diversions are currently the next best option to “letting nature do its thing”.
Of course there is no actual “total” solution as long as the river is bottled up along its entire length.

The state needs to focus on manual land building. They're doing that on other parts of the coast and it works very well. The amount of land created for the cost and time scale is hilariously small.
In 45 years and billions later...

Agree. But I believe there needs to be a dedicated dredge in the inlet to feed the diversion so it doesn’t have to run as much as currently planned. I also believe there should be controlled outfall in the Barataria Basin. They should build ridges to slow the water to build land quicker similar to West Bay. I also think they need to channelize the fresh water for a quicker route to the Gulf.
The problem the State faces is that they unnecessarily overstated the benefits of the project while understating the impacts. It’s going to come back to bite them … but it won’t kill the project. There will be a compromise on the operation which is the logical and sensible.

If there is one thing the dutch have perfected in the modern world, it is anything relating to civil engineering. their transportation methods are unmatched and no where near our car dependent transportation system and like you pointed out, reclaimed land from coastal land loss.
We definitely need to take notes from them
Having spoken with some engineers from over there, their answer was pretty simple: "We invest in the land and the people." Infrastructure is a high priority over there, and it is one of our lowest.

Exactly. However, their entire country is faced with the same fate which makes unity possible unlike our situation in which we have to convince folks from Kansas to pay for projects in a swamp.

I saw they predict it will build over 21 sq miles of land in 50 years. Over that time I believe it should reduce storm surge.

The river carries about 10% the sediment now as compared to when it built the delta. Levees all the way up to the headwaters is the main reason. The diversions will build land at a glacial pace compared to dredging and pumping. In a perfect world we would do all the above. Sadly the coast is already mostly gone and they are not going to save it.

Correct, dredging and pumping is a much quicker solution to rebuilding land. The new areas need to wrapped in rocks in order to prevent any further erosion.

This is a much-parroted talking point that is at best an uneducated take. It’s like arguing you would pass on a winning Powerball ticket because last month there was a much bigger winning ticket.
The Corps takes 15-20 million cubic yards of sand out the river below Venice every year to keep the channel open. That’s JUST Southwest pass, not any other location in the delta or elsewhere in the river or any other channel across the coast.
Sand comprises about 20% of the river’s total sediment load, with finer silts and whatnot comprising the remaining 80%. So you have tens of millions of cubic yards of material moved by the river every year that is not dredged.
Last year, CPRA’s biggest dredging year ever, they managed to move 22 million cubic yards of sediment COASTWIDE. So what does all that mean? Every year, the Corps digs a hole in one spot refilled by the river annually equivalent to the myriad of holes CPRA had to dig from lake Calcasieu to Breton Sound and in the Gulf for their biggest year ever.
There’s plenty of sediment in the river.

I never really understood why we dumped $3 billion on a project that will be irrelevant in 50 years. Coastal Restoration is a scam. It will eventually just erode away... like it already has.
$3 billion would go a long way in fixing our traffic problems and bad roadwork in this state.
Reading through this thread, so far yours is the only stupid frickin' post I've seen.

Plaquemines suing to stop a land-building project because they’re worried about flooding is peak Louisiana.

Most of that stuff isn't really protected by the river levee... it's all built up or behind ring levees. Some improvements to the ring levees will be needed and maybe some other building up.

This project has ZERO to do with shipping

Why would the river shoal in?
Removing the last section of levees would allow for the natural ebbs and flows of the river and natural spring flooding?
Why "mimic" the old river floods with diversion canals, when you can actually have the real thing?
Diversion canals while better than nothing, is going to overshoot the sediment by pushing water through too fast. Some will settle in the right places, yes, but it's not the best solution.
And if somehow sediment was getting set in the river channel, we do what we do now... dredge.
