I can't argue about the sustainability but I can clarify some things about this airport and the town it's in.
The runway is in good shape. It is not a private airport.
One end is acres of blackberry bushes, then highway, then lake, industrial zone, and flood zone farmland.
The other end is state fairgrounds and race track where every week thousands gather for the races, demo derby, and fireworks show, etc. It's so loud it rattles every window in town and people are always getting injured and dying. Happens when they practice weekdays too. I think one time somebody made the mistake of trying to complain about it on the town FB page.
