In SC, we have Commissioner Emeritus status for retiring district commissioners (supervisors). The guidelines are fairly brief:
Definition: The title "Emeritus" conferred upon an individual is used to formally designate someone who has been honorably discharged from the performance of public duty for long and faithful service but still is interested in the local conservation district. Upon retirement and recommendation by the Conservation District Board, it is appropriate for the DNR- Land, Water, and Conservation Advisory Committee to confer the title of Conservation District Commissioner Emeritus upon deserving individuals
This title does not confer any powers or responsibilities but is in recognition of faithful service to the local conservation district.
Guidelines:
The following guidelines are intended to be used to establish minimum criteria that an individual must meet in order to have the title of Commissioner Emeritus conferred upon them.
1. Length of Service as a Conservation District Commissioner
2. Contributions and significant accomplishments to the Natural Resources
3. Character
4. Leadership
5. Service to the Community and State
6. The Candidate shall be recommended in writing by their Conservation District
