I never have inacted beautiful ordinance (I will at some point), from what I've read you do not get trash/garbage when its in force.
So that is one that can't be completed (its usually a daily ordinance?)
I've got Bell boom on and in another town, nothing inacted, and neither get that much garbage anyway.
If you see a medium size shadow in the little ponds, that will be trash, but, well for me, its rare to see.
There is more than one I can't complete (another is buy an axe and all I often have is the watering can for sale, TIY store, not emporium). I just do the ones I can & I play the alts to gather a few more coupons.
