Your plan that you filed... to deal with this specific problem... that's on file with the city of New Orleans so that you can embarrass them with it...? That's going to be available, right? Boy oh boy... will you ever have the last word on them.

Sad to say that your stinging insight won't address the problem that these days, the engineers that win the low bid to DESIGN INFRASTRUCTURE LIKE THIS can barely speak english.
