In the event that a preliminary site plan identifies the potential need for dimensional variances, the applicant shall first be denied preliminary site plan approval by the Planning Board, before appealing the need for such variance(s) to the Zoning Board of Appeals. Where the Planning Board has denied such site plan on these grounds, the Planning Board shall convey its opinion to the Zoning Board of Appeals on the requested variances. Once variances have been granted, the applicant may proceed for final site plan approval. If the variances are denied, the applicant shall submit a revised site plan complying with the dimensional requirements of the zoning district.
