§ 18.02. Enactment, revisions, modification or changes of zoning regulations.

Zoning regulations shall be enacted by the council only on the basis of a comprehensive plan prepared by the metropolitan planning commission in accordance with the applicable state laws and as provided in section 3.05 of this Charter.

Any revision, modification or change in the zoning regulations of the metropolitan government as provided in this section shall be made only by ordinance. Where a proposed ordinance revises, modifies, or changes the zoning regulations and is not accompanied at introduction by a favorable recommendation of the metropolitan planning commission, a copy thereof shall be promptly furnished by the metropolitan clerk to said planning commission, and the same shall not be passed on second reading until the recommendation of said planning commission with respect to the proposal has been received or thirty (30) days have elapsed without such recommendation. No ordinance making any revision, modification or change in the zoning regulations which has been disapproved by the metropolitan planning commission shall be finally passed or become effective unless it shall be adopted by a two-thirds majority of the whole membership of the council and also then be approved by the metropolitan mayor, with a three-fourths majority of the whole membership of the council required to override a veto.
