When is the change of an existing geographic name appropriate?
Stability in the use of geographic names is important to reduce confusion and to minimize costs associated with changing names; thus, changes in existing geographic names should only occur where a proponent provides substantial evidence of a compelling reason for the change. Proposals to change names that have recently (less than five years) been adopted by the board on geographic names will very rarely be considered by the committee on geographic names. Generally, the following three classes of proposals may justify the change of an existing official name:
Committee decisions to change a name or to adopt any specific name will consider all relevant factors regarding name proposals as well as other committee policies, documented usage, population density, and state, tribal and local government needs.
