surprised they dont have better stormwater management/drainage systems
The water management infrastructure is excellent. But it was designed to cope with century floods, not the kind that happen every other century.
Edit: the drainage systems were in fact designed to cope with a once-in-200-years flood. But this was a 500 year flood. A quarter of Hong Kong’s annual rainfall poured down in a day—and this is a place with notorious rain storms through the summer
They also just had a typhoon, which means there was probably a lot of debris making things worse.
Debris and saturated land so the water had nowhwre to go.
but they will now, right? right?!
There are some events that are costlier to plan for than to clean up after. I’m not sure if this is one of those, but…
It's all engineers to some limits that are expected. This was not within those limits.
Same thing with Texas and the cold front. Of course Montreal could have dealt with that easily but they expect that sort of thing.
I have never seen the city like this; I'm glad I'm not there rn. There are some rumours about how because the government sealed brick paths with glue following the protests the drainage is weaker, but idk how true that is
I’m sure that didn’t help but that’s a drop in the proverbial ocean. There have been many severe rainstorms since that happened and nothing like this occurred
Yeah for sure, this is after all a record storm. That's the main cause probably.
