Whether Iowa Code section 358A.8 required an affirmative recommendation by the county zoning commission before the Board of Supervisors could consider and approve a rezoning petition.
Holding
No. The Commission's tie vote did not prevent the Board from considering or acting on the rezoning petition.
Reasoning
Iowa zoning law assigns different roles to the two bodies: the zoning commission is an advisory, recommending body, while the board of supervisors is the legislative decisionmaker. Treating an affirmative Commission vote as a prerequisite would improperly give the advisory body power to defeat a rezoning request before the Board could exercise its legislative responsibility.
The statute provides that the Commission "may" recommend amendments to the Board. In ordinary statutory usage, "may" confers authority rather than imposes a mandatory duty. A recommendation is also advisory, not binding. Section 358A.8 therefore does not grant the Commission a veto over rezoning applications.
