Just use purely native grasses mixed with wildflowers, and don't bother with weeding or feeding it, and let the rains wet it.
It won't be so pretty, but the problem is, the notion of what humans think is "pretty".
Fields of grass are nice, but only if you really need them for doing stuff on.
Compost the clippings (along with other organic waste, of which I'm sure there are literal TONS of at any park, especially if they include zoological displays. ie, the Calgary Zoo sells composted "Zoo Poo" as fertilizer.)
