Each zoning district provides for "similar uses." If a proposed use is not explicitly listed as a permitted or special land use in any of the zoning districts, an application for determination of similar use shall be made to the Planning Commission. If a use is determined to be similar to a use listed in a particular zoning district, the proposed use shall comply with the standards that apply to the similar use. If the Planning Commission determines a proposed use is not similar to a use in a particular zoning district, the applicant may petition for an amendment to the chapter, as described in § 170-40.7. Based on information provided by the applicant, the Planning Commission shall determine if the use is similar by considering factors such as, but not limited to, peak-hour use, nature of use, aesthetics, traffic generated, noise, vibration, dust, smoke, odor, glare and other impacts in terms of health, safety and welfare.
