I’ll be the one to say it: that’s just stupid.

Lifeless monoculture lawns are as big a waste of resources as car centric infrastructure. Doubly so when it’s in a place where humans can’t even walk on it. Triply so when it’s in a spot where it will gum up and corrode the rails it’s trying to hide.

Better than pavement. Of course some native grasses would be better, but this is still an improvement.

But how exactly is it better? Nicer to look at maybe, but there are other materials that can provide drainage and temperature control with better durability and less maintenance.
