Zoning

Chapter 355 of the Iowa Code delegates zoning authority to counties. This power, together with the authority that is possessed by all Iowa counties because of their home rule status, gives counties broad discretion in directing development and controlling future growth. The Lyon County Flood Plain Ordinance is incorporated in the Lyon County Zoning Ordinance Article 15.
