Special Use Permit
Most land uses are only allowed to operate in certain Zoning Districts. Some uses cannot be allowable generally in a particular zoning district, but may be allowed under special conditions. Such uses require Special Use Permit approval. Refer to the Section three of the Zoning Ordinance or contact the Community Development Department to confirm that the proposed land use is permitted at the specific site. Special Use Permit approvals require a Formal Public Hearing. The Plan Commission holds a Public Hearing and provides a recommendation to the City Council. The City Council makes the final decision on the petition.

In recommending or granting approval or conditional approval of a Special Use, the City Council and Plan Commission shall prepare written findings of fact that on the basis of the characteristics cited under Review of Special Uses Section seven of the Zoning Ordinance or changes to such characteristics that conditions to which the approval is made subject require the proposed use will be compatible with existing uses in the area, and with Permitted Uses in the zoning district, in the following ways:

1. Traffic: Any adverse impact of types or volumes of traffic flow not otherwise typical in the zoning district has been minimized.
2. Environmental Nuisance: Any adverse effects of noise, glare, odor, dust, waste disposal, blockage of light or air, or other adverse environmental effects of a type or degree not characteristic of Permitted Uses in the zoning district, have been appropriately controlled.
3. Neighborhood Character: The proposed use will fit harmoniously with the existing natural or man-made character of its surroundings and with Permitted Uses in the zoning district.  The use will not have undue deleterious effect on the environmental quality, property values, or neighborhood character already existing in the area or normally associated with Permitted Uses in the district.
4. Public Services and Facilities: The proposed use will not require existing community facilities or services to a degree disproportionate to that normally expected of Permitted Uses in the district, nor generate disproportionate demand for new services or facilities as compared with the Permitted Uses, in such a way as to place undue burdens upon existing development in the area.
5. Public Safety and Health: The proposed use will not be detrimental to the safety or health of the employees, patrons, or visitors associated with the use nor of the general public in the vicinity.
6. Other Factors: The proposed use is in harmony with any other elements of compatibility pertinent in the judgment of the Commission or Council to the particular Special Use or its particular location.
