The Fire Ward division for the city did not solve the problem of
locating homes entirely, so in 1922, Fire Chief G.S. Walker, Frank
Smith, J.N. Lacey and J.L. Ghere proposed a better naming system, the
one that is still in use today. It was determined that Broadway and
Main would be dividing streets.

Commercial Street would retain its name and College Street would also
because of Haskell College, which was located on its East end. Streets
north of Broadway would be alphabetical and named after cities North
of the Mason-Dixon line; streets south in alphabetical order after
cities south of that line. Streets east of Main would be numerical,
and streets west would be named alphabetically after trees.
