Building multi-decade service life infrastructure on the coast in this era of the Anthropocene actually requires you (from an engineering point of view, not merely a regulatory one) to have a buffer zone of wetlands, marshes and sea walls to absorb storm surges.
You can still choose to read that cynically, but I think the cynical angle is taking moral ecological credit for a pragmatic engineering reality :P
To be clear, I'm not trying to argue that this project is ecologically beneficial or neutral (I think that part is beyond debate for many reasons including the noise pollution you've identified)
I was just trying to say that the marshland restoration stuff is likely not lip service, insofar as they actually do need wetland buffer zone to keep their launchpads above sea level.
