76-2-106. Adoption of development district. (1) Adoption by the planning and zoning commission of the development district or any change therein may be in whole or in part but must be by the affirmative vote of the majority of the whole commission, provided, however, that prior to any such adoption, a public hearing shall have been held not less than 15 days after notice thereof shall have been posted in at least three public places within the area affected.

(2) The resolution adopting the district or any part or parts covering one or more of the functional elements which may be included within the district shall refer expressly to the maps, charts, and descriptive matters forming the pattern or part thereof. The board of county commissioners shall have the power to authorize such variance from the recommendations of the planning commission as will not be contrary to the public interest, where, owing to special conditions, a literal enforcement of the decision of the planning and zoning commission will result in unnecessary hardship.
