(A) The use of avenue, parkway, trail, drive, boulevard, way, court, terrace and circle suffixes must be used in identifying location and direction of roads.
(B) Roads must be designated as follows:
(1) Roads that run north and south are alphabetical avenues or terraces.
(2) Roads that run east and west are numerical avenues, trails or ways.
(3) Roads that both originate and terminate on the same street, avenue or boulevard, are circles.
(4) Cul-de-sacs (dead ends) are named courts.
(5) A road must have only one name for its entire length.
(6) Two roads must not be named alike, that is, have the same name or have similar sounding names.
(7) The name of a road may change only if the road changes direction 45 degrees or more at the point of deviation.
(8) All private roads must be labeled lanes and must maintain numerical and alphabetical sequence.
(9) Meandering roads must be labeled boulevard, drive or parkway.
(10) If the proposed street is an extension of an existing named street that name must be used. In all other cases the name of any street previously used within the county must not be used, unless such use is consistent with the county or community street naming system.
(11) The above named requirements may be modified in cases where the Fire and/or Police Departments recommend modifications to facilitate their providing for the safety of occupants of the subdivided lands. In some areas, changing the name of a street would confuse rather than assist the Fire and Police Departments.
