Plaquemines Parish levees from Port Sulphur to Venice have been overtopped 3 times in the past 47 years and they were all from Cat 3 (Betsy, Camille, and Katrina) or higher storms. The problems in Plaquemines parish (west bank side) was around Myrtle Grove area which basically has no levee on the marsh side. This area floods for tropical storms due to the almost non-existent levees.
I agree something needs to be done with coastal restoration, just not sure it is feasible to blow all the levees. That would be better in the long run but that is not going to happen with the people in the area, industries in those areas, and the largest oyster producing area in the country.
