"Just listening to re-run of Dennis Prager show, and he had a guest on who was talking about the disaster and topic of other cities that have been elevated ,, Seattle and sacramento are two examples, but these were done years ago. "
Sacramento? Are you sure? Sacramento is inland...nowhere near the coastline. Seattle is on Puget Sound and the Olympic mountains are west of the Sound.
I heard that the Army Corp. of Engineers had requested millions to add a higher levee for N. O. but it got turned down.
Yup.. Old Sacramento, now a historic district, was founded on the banks of the Sacramento river and was subject to frequent floods until leveees were built. The area directly East from the Bay Area towards there has an extensive network of levees that were built years ago.
One of these years heavy rains will burst some of the big ones and look out.
Every once and a while one will rupture and sizeable acreage will be underwater 'til the levee is repaired and the water drained..
