Allow minimum and/or community custody prisoners to do the work, for time off their sentences.  Of course you would have to argue with the unions and contractors, who have "dibbies" on every little bit of brushing or picking up.  And you would have to pay for extra guards to supervise them.  And of course there would be the occasional "walk away" to terrify the weak kneed.  So horrifying to have a real shoplifter or DUI near your homes ... as if they don't surround you already.  In reality, the people without some sort of criminal record, or who simply haven't been caught yet, are a small minority.
