At least every five years, but no sooner than every three years, City Council and the Mayor shall appoint a Charter Review Commission composed of 11 members. To avoid conflict of interest, no elected City official or employee shall serve on the Charter Review Commission. Nothing herein shall preclude such officials from attending or participating in the actions of the Commission. Seven members of this Commission shall be appointed by City Council and four members shall be appointed by the Mayor. All appointees shall be current residents and registered voters of the City. The Charter Review Commission shall review the current Charter, submit a report to the City Council, the Mayor, and the citizens of the City, within six months of its appointment, and recommend any proposed amendments to the Charter. City Council and the Mayor, by ordinance, shall place all proposed amendments on the ballot no later than the next municipal election. City Council shall provide appropriations for the reasonable expenses incurred by the Charter Review Commission.
