On or before July 1 of each year in which a presidential general election is held, the civil service commission shall review and make a written report to council, which report shall be filed with the clerk of council and the office of the mayor, setting forth the commission's recommendations for the salary and other compensation for the offices of mayor and members of council. Council shall place that report on the next docket at a regularly scheduled council meeting. If council takes no action or fails to decline to follow the suggestions within 90 days, the recommendations shall take effect as if council had adopted them by ordinance approved by the mayor. However, no increase in salary under this section shall exceed 10 percent of the salary for the office of mayor or council, unless there has been no increase in salary for that office in the preceding 10 years.
