167.31 OVERLAY AND SPECIAL DISTRICTS.
      1.   Purpose. Overlay Districts are used in combination with Base Districts to modify or expand base district regulations. Special Districts are not used in conjunction with a Base District, but otherwise serve the same purpose as Overlay Districts. Both districts adapt to the special needs of areas of the city and further allow Denison’s Zoning Ordinance to evolve as the planning and development needs and trends of specific areas also change. The Overlay and Special Districts are designed to achieve the following objectives:
         A.   To recognize special conditions in specific parts of the City which require specific regulation.
         B.   To provide for the protection of special features in the natural and built environment of the city.
         C.   To allow for change and adaptability to different needs and trends in land development.
         D.   To encourage comprehensive neighborhood and environmental planning in the city, and to protect the integrity of vital city services such as the water supply and airport operation.
         E.   To provide flexibility in development and to encourage innovative design through comprehensively planned projects.
      2.   Establishment of Districts. The following Overlay and Special Districts are hereby established.
