All farms in existence upon the effective date of this chapter and all farms which are brought into the city by annexation shall be a permitted use. All dwelling units and structures for processing of farm goods shall require a zoning permit and conform to all requirements of the City Code. The City Council may require any new farm operation to secure a conditional use permit in the event of the following:
(1) The farm is adjacent to or within 400 feet of any dwelling unit and may be detrimental to living conditions by emitting noise, odors, vibrations, hazards to safety, and the like.
(2) The farming operations are so intensive as to constitute an industrial type use consisting of the compounding, processing, and packaging of products for wholesale or retail trade and further that such operations may tend to become permanent industrial type operation that cannot be terminated as can a normal farming operation.
