do you people care that you don't know what you are talking about? The lake borgne barrier wall is a combo wall system very easy to build in the marsh. What they are doing in NYC is way different. And to my knowledge that 200 billion number is way off.


Considering it was the first of its kind ever built (design-build) and it has experienced massive stabilization problems due to current undermining the huge cement base in the channel, contributions to major land loss due to water turbidity & flow, and I’m not going to go into the negative ecological impacts of the project I would say the ecological damage & on-going maintenance costs will be astronomical for NY.

Also that water has to go somewhere which means other areas outside the wall will see increased flooding of historic portions.

Combi-walls are nothing new. it was just the largest design build the corp had done to date.

so tell me more about these stabilization issues. Being a combi wall system would only see stability issues under load and it hasnt seen a hurricane yet, i dont believe you when you are saying it is seen "Massive stability issues". So where are you getting your information. Im talking the wall, not the sector gate, barge gate or lift gate.

No for the 2nd part of your statement, the ecological impacts are an issue. There are multiple reasons they just dont build a wall and massive gate somewhere in the Lower Bay. a lot has to do with eh tidal flows in the estuary. Try and find the studies done in Jamaica Bay. That was a huge factor. And the impacts the LBSB isnt as massive as you are making it out to be. it is one of the hottest fishing areas now.
