...the 2025 Building Code has Edmonton's 15min rain event as 29mm. Drainage systems are currently designed for that, although I don't know how that has changed over time.
We got 22.7mm from 7:30~8PM, and then another 7.3mm after 8PM.

...July is usually our rainiest month, averaging 88mm. And after July 10th's storm Blatchford is about halfway there. https://public.tableau.com/shared/64KKM8KJB?:display_count=n&:origin=viz_share_link
