You don't plan these systems on the worst possible scenario.
I found this in an advocate article: "The city's pumps are able to handle 1 inch of rain in the first hour and half an inch of rain each hour after that."
So anytime there's a few inches of rain within two hours the city is screwed I guess.

It's sad to acknowledge this dude is politicizing his organizations failures? What exactly is sad about it?

well he is contradicting himself
if he truly believes these types of events will occur more often, then the system should obviously be improved

10 inches in hours is a once in a century level storm.

This is true.

Re-engineering the pumping/drainage system is what's is needed instead of excuses and wasting money on other unrelated things. (Insert CSA Officer monuments comments here).

Im hearing stories as much as 10 inches in as little as 5 hours in a couple of places.

2 inches per hour? Ha, if the system isn't designed to handle that then you are wasting your time. I expect this has more to do with poor maintenance. I tried to look up the directors resume. I don't see where he has any kind of civil engineer / stormwater design in his background. This is absolutely crazy that you don't have someone highly experienced in stormwater design/capacity in charge.

Using climate change as any sort of excuse for the feet of flood water in the city is a shame.

Probably never. That system shouldn't be at full capacity for a rainstorm.
2 inches of rain in 3 hours is max capacity for the system.
1 inch in the first hour, and half an inch owe hour after that. It's comical.

New Orleans - too busy tearing down statues to fix drainage problems.

Those monuments are gone like any money I would have spent in NO. Time to move on.

Hell, even if you use climate change as a reason, you're admitting it's a problem that's only going to get worse.

10 inches in 5 hours is 7 more inches than the system is designed to handle in that amount of time.

"We're in an era of climate change,'' Grant said, adding that rain events like the one Saturday will happen more and more.
So, let's just pretend that this fairy tale is true. What are they going to do about it? I know stopping this made up climate change isn't an overnight process, so then what? Just keep accepting the floods?
Now back to reality....

the system was working as it is designed to, calling it "pretty amazing.''
Was designed properly? I mean I can design and build a paddle wheel-like pumping station with an erector set and a few spoons to move water and have it "work like it is design to work", but is it sufficient? I completely understand that the rain event was an intense event, but I would bet that it is pretty close to what happens when strong hurricane makes landfall between Biloxi and Lake Charles. Seems like those kind of events should be what the city designs their systems for.

Evidently "climate change" stops at the Jefferson Parish line....
Same amount of rain, no major flooding..

The system hasn't been designed to handle that since inception. I think it has surge capacity during hurricanes, but they can't just flip a switch for that.
Consider this the cost of doing business in a city below sea level.

A 100 year storm should actually be the design standard. It is in a lot of places.
And I can't believe I'm doing this, but SWB is correct. Their system worked - most likely (haven't seen evidence otherwise). Nola residents should be looking at DPW instead. DPW is in charge of drainage pipes <30" diameter, which is what most likely caused the backups this past weekend.

NOLA residents seem to be the only people in the world who live in a bowl and can't figure out why water keeps collecting there.
I literally live in the absolute lowest of the lowest part of New Orleans, the bottom of the bowl and the water didn't even get over the curb on my street.
It doesn't matter where you live. 8-10 inches of rain in 2 hours, no pumping system in the world could keep up with that.
