When an application for either a special exception or a conditional use has been filed with either the Zoning Hearing Board or the Board of Supervisors, as relevant, and the subject matter of such application would ultimately constitute either a land development or a subdivision, no change or amendment of the Zoning Ordinance shall affect the decision on such application adversely to the applicant, and the applicant shall be entitled to a decision in accordance with the provisions of the Zoning Ordinance as it stood at the time the application was duly filed; provided, further, that should such an application be approved by either the Zoning Hearing Board or the Board of Supervisors, as relevant, the applicant shall be entitled to proceed with the submission of either land development or subdivision plans within a period of six months or as may be approved by either the Zoning Hearing Board or the Board of Supervisors following the date of such approval in accordance with the provisions of the Zoning Ordinance as it stood at the time the application was duly filed before either the Zoning Hearing Board or the Board of Supervisors, as relevant. If either a land development or subdivision plan is so filed within said period, such plan shall be subject to the provisions of Article V of Chapter 315, Subdivision and Land Development, of the Township's Code and Section 508(4) of the Municipalities Planning Code.[1]
