In the case of a request for a special use permit approval and for a site performance development, the Planning Commission shall, after review of the special use request and site plan, hold a public hearing in accordance with § 20.02:3 and make a final decision in accordance with §§ 20.02:4, 20.03 and Article 22. Where a site plan is required in conjunction with a permitted use (except a site performance development) that must conform to the standards in Article 22, the Zoning Administrator shall have the responsibility to approve, approve with specified changes and/or conditions, or disapprove the applicant's request, using the site development requirements in Article 22 and the general standards in § 20.03:1.
