     (a) The governing body of any city or town may initiate

           (ii)   The governing body shall:

               (A) Cause to be prepared a legal description, a
listing of the current mailing address of each landowner as
shown in the records of the county assessor and a map showing
identifiable landmarks and boundaries of the area considered for
annexation and the area which will, as a result of the
annexation then be brought within one-half (1/2) mile of the new
corporate limits of the city, if it has exercised the authority
granted under W.S. 15-3-202(b)(ii);
               (B) Determine if the area considered for

procedure outlined in W.S. 15-1-405 and 15-1-406 shall then be
followed. If the area does not comply, no further action shall
be taken on the proposed annexation.
