I'm so old I can still remember when Sechseleuten Square was green grass, now replaced with searing heat assemblers of stone....so even the city is working against that sponge thing, but yeah it sounds good from a politician's mouth.

It's a relatively novel concept, though the problems of replacing open surfaces with stone slabs and asphalt could have been obvious decades ago :(

Ah, but you see, stone slabs and asphalt cost nothing to maintain. /s

(...Even this is, of course, untrue, but it seems true when you're only paying attention to the next year or so.)

Just 17 milion swiss franks made out of "Valser Quarzit" and a "fountain" that needs constant maintenance because it has to be drinking quality instead of lake-water, just look at that sh*t:
