You can't really build for the 1000 year flood, I guess you could, but it would get very big and expensive very quickly, so instead we only build for the 100 year flood and hope that we aren't the next Ellicott City, Maryland and get two, 1000 year storms less than two years.
The problem with the 100 year flood is that thanks to climate change, poorly planned levies, other environmental changes, it could easily be a 10 year flood in the time the infrastructure is intended to last.
That being said, hopefully they've gotten it right, I've not seen flooding at the King grade separation, like we saw at the Weber grade separation after it was built.
The one that trapped 2 of the TTC's new Flexity Outlooks was aggravated by a water main break at the same time.
