Thanks, Steve, that is fantastic.
I think that if you just take the same water bill, you should be able to purchase as much compost as you need. I don't think they're limiting it to one load per Fayetteville resident.
BTW, I didn't think of this before, but of course I will compensate for all purchases! Show up with a trailerload of compost, get $20.
About mulch, I'm actually on the fence about using it. I read about an interesting technique for dealing with clumps and large debris, like rocks, where you just rake the top of a raised bed, and these things get concentrated on the sides of the beds and into the paths, where foot traffic breaks up soil clumps and rocks can be picked up. To restore beds for the next growing season, paths can just be shoveled lightly. Sounds like it could be unpleasant after wet weather, though. We might want to just use carpets, which we could tilt to one side to dump debris and sweep soil back onto the beds. Or we could just carpet and mulch a bit narrowly, leaving a strip of bare soil on either side of the beds. Thoughts, anyone?
