That mill pond's water lilies have been filtering runoff since the 1920s, something no drainage system in the new plaza can match. Those old stones act like a sponge, slowing down floods after heavy rain. But now with all that concrete, where does the water go? Straight into the sewers, overloading them. Doesn't that just push the problem downstream?
Wait what? The water lilies have been cleaning the water since the 1920s? That's insane, I had no idea it was that old. They just paved right over a system that's been working for a century. No way some new drains are gonna be better than that, it's just gonna cause more problems.
