Hey thanks for a very interesting and thought provoking reply. I lived in NOLA for 10 years and long may it live! Spot on with the destruction of the marshlands - something so desperately needing reversal.

I was just wondering if you could provide a citation for this:

>>>Worst case sea level rise estimates easily gives New Orleans 300+ more yrs

I hope so. I fear not.

Talking to my friends in the city it feels like if ida had spooled up 1 day further out, it would have wiped the place off the map. I know it isn’t true, but man, the wetlands are so mostly water below town, the storm didn’t loose strength, the next time… etc. I hope ida was the second-order wake up call the city needed to survive a future cat 5 with 30+ foot storm surge.




The LA CPRA coastal master plan, combined with army corps of engineers studies on further improving the post-Katrina levees.

I'm trying to find the levee recommendations, but Biden's takeover seems to have broken all my bookmarks in the ACOE website.

Basically it's just the ipcc/ epa most-likely-worse case scenario with some local adjustments, combined with CPRA's master plan for surge reduction and (non-nola) coastal protection and barrier island rebuilding, combined with the Corps' recommended levee improvements.

You end up with lessened storm surges and raised levees that can match sea-level rise to whatever hight is feasible for the look levees, and back-out the years from the projected rate of sea level rise.

And if they do the wall across the Orleans land bridge (preventing storm surge at the Rigolets and chef's pass), it's actually a much higher number. But that plan is on the back burner for now.


Thanks for all the context!
