1321.01 GENERAL.
   Planned unit developments shall be allowed by planning commission approval in any zoning district. No such planned unit development permit shall be granted unless such development will meet the use limitations of the zoning district in which it is located and meet the density and other limitations of such districts, except as such requirements may be lawfully modified as provided by this code. Compliance with the regulations of this code in no way excuses the developer from the applicable requirements of a subdivision ordinance, except as modifications thereof are specifically authorized in the approval of the application for the planned unit development.
   These regulations are to encourage and provide means for effecting desirable and quality development by permitting greater flexibility and design freedom than that permitted under the basic district regulations, and to accomplish a well balanced, aesthetically satisfying city and economically desirable development of building sites within a PUD-Planned Unit Development. These regulations are established to permit latitude in the development of the building site if such development is found to be in accordance with the purpose, spirit and intent of this ordinance and is found not to be hazardous, harmful, offensive or otherwise adverse to the environment, property values or the character of the neighborhood or the health, safety and welfare of the community. It is intended to permit and encourage diversification, variation and imagination in the relationship of uses, structures, open spaces and heights of structures for developments conceived and implemented as comprehensive and cohesive unified projects. It is further intended to encourage more rational and economic development with relationship to public services, and to encourage and facilitate preservation of open lands.
