Zoning regulations and boundaries may be amended or repealed. If the purpose and effect of a proposed map amendment is to change a zoning classification, the legislative body shall make findings of fact that address: population change; the availability of public facilities; present and future transportation patterns; compatibility with existing and proposed development for the area; the recommendation of the planning commission; and the relationship of the proposed amendment to the local jurisdiction’s plan. The legislative body may grant the amendment to change the zoning classification based on a finding that there was: a substantial change in the character of the neighborhood where the property is located; or a mistake in the existing zoning classification. The legislative body shall keep a complete record of a hearing on an application for reclassification and the votes of the members of the legislative body. A legislative body may not allow the filing of an application for a reclassification of all or part of any land for which a reclassification has been denied by the legislative body on the merits in the 12 months before the date of the application. The provisions of § 4–203(b) of this subtitle concerning public hearings and notice apply to applications for reclassification.
