155.3701. GENERAL
   A.   General Purpose of Overlay Zoning Districts
Overlay zoning districts are superimposed over portions of one or more underlying base zoning districts (and perhaps planned development districts or other overlay districts) with the intent of supplementing generally applicable development regulations with additional development regulations that address special area-specific conditions, features, or plans while maintaining the character and purposes of the underlying zoning districts. Some overlay zoning districts include standards that modify or supersede standards applied by the underlying base zoning district.
   B.   Classification of Overlay Zoning Districts
Land shall be classified or reclassified into an overlay zoning district only in accordance with the procedures and requirements set forth in Section 155.2403, General Zoning Map Amendment (Rezoning), or Section 155.2404, Site-Specific Zoning Map Amendment (Rezoning), and this part.
