Uses listed in the zones or sections of this title as permitted subject to conditional use permit may be so permitted when such uses are necessary to the development of the community and are in no way detrimental to surrounding properties or uses permitted in the zone. In granting the permit the commission may require certain safeguards and establish certain conditions to protect the health, safety and general welfare. Uses existing on the effective date of the ordinance codified in this title which are listed as permitted in this title, subject to a conditional use permit, in the zone in which they are located, may continue without securing such a permit; however, any extension or expansion of such use shall require a conditional use permit. This chapter shall not apply to conditional use permits granted pursuant to Ordinances 329, 326 and 317.
