I do wonder exactly what the theory of change here is - this is a huge amount of money, and I am surprised it's a great way to spend it, especially when the Inflation Reduction Act just authorized so much money for similar goals. I didn't dig into the individual grants, though the ones I peeked at didn't get too specific on what that work is.
Parks, trees, and community gardens are all great. My general expectation in my experience is that poor urban communities are disproportionately often in park-heavy areas (not for justice reasons, for floodplain reasons). I guess they need work to make them better? I like community gardens, but I am just shocked if folks are helping much to solve anything that matters by dedicating dozens or hundreds of millions of dollars to promoting them.
I am extremely skeptical that the climate mitigations cited are very well-accomplished by the green spaces mentioned. It's obligatory to cite climate change in everything, which gets frustrating, especially because we are engaged in so few of the things that would actually help.
