Since July 1, 1992, Members of Council receive an annual salary of $8,500, and the Mayor receives an annual salary equal to that of a member of Council plus 33%. Beginning on July 1, 2020, the compensation of the Mayor and Members of Council shall be increased to reflect an ad-hoc cost-of-living increase based upon the increases in the National Consumer Price Index for the time period of July 1, 1992 through July 1, 2020, but in no case shall such increase exceed three percent (3%) per annum. This shall be a one time adjustment in 2020 in compensation not an annual, recurring adjustment in salary thereafter. Neither the Mayor nor any member of Council shall receive additional emoluments, allowances or bonuses on any account: Provided, that the Mayor and members of Council may participate at their own expense in any group insurance program offered by the City of Wheeling to its employees, consistent with the terms and requirements of such policy.
