763.01 CIRCUMSTANCES JUSTIFYING AMENDMENTS; REVIEW OF AMENDMENTS.
   Recognizing the dynamic character of an urban area, both the Zoning Map and the text of this Planning and Zoning Code may be amended periodically in order to keep it abreast of new zoning techniques; whenever a general hardship prevails throughout a given zoning district; whenever a change occurs in land use, transportation or sociological trends either within or surrounding the community; and whenever extensive developments are proposed.
   Review of a proposed zoning amendment shall assure that any changes made will adhere to the development plans and objectives of the City; will not be detrimental to adjacent property owners, structures or uses; and will maintain the health, safety, and general welfare of the community.
