An elected officer who wishes to resign may do so by submitting the resignation in writing to the Clerk so that it shall be properly recorded and considered. A person who resigns from an elective office during the term for which that person is elected is not eligible for appointment to any City office if the office has been created or the compensation of the office has been increased during the term for which that member is elected. A person who resigns from an elective office is not eligible for appointment to the same office during the time for which the person was elected if, during that time, the compensation of the office has been increased.
