First, you pick something short and out of the way -- like, oh, I dunno, Shepherd Road, near Forest Lane and Greenville Avenue. Then you name it for a pastor who, in 2007, got a post office named for him, courtesy Pete Sessions' bill two years earlier. (It's for either that Robert E. Price or the probate judge; more than likely, the former.) Then you get city staff to offer its approval; then you take it to the City Plan Commission, no big whoop. Done deal, more than likely.
Or, even better, you take an even shorter street with a more generic name (Beechwood Avenue) and go with something equally nondescript (Pathfinder Drive). Just don't tell Missouri about "Llewellyn Court." --Robert Wilonsky
