Salaries for City Council Members shall be uniform. Salary increases established by the Salary Commission shall be effective on the first pay period of the year following the decision of the commission. Salary decreases established by the Salary Commission shall become effective as to incumbent City elected officials at the commencement of their next subsequent term of office.
