The Planning Board shall render a decision no later than 120 days after the date an appeal is taken from the decision of the Zoning Officer, or no later than 120 days after the date of submission of a complete application to the Planning Board where no prior application was made to the Zoning Officer. Failure of the Board to render a decision within such one-hundred-twenty-day period, or within such further time as may be consented to by the applicant, shall constitute a decision favorable to the applicant. In the event that the developer elects to submit separate consecutive applications for the variance and for subsequent site plan, subdivision and/or conditional use approval, the one-hundred-twenty-day period shall apply only to the application for approval of the variance and the time period for granting or denying any subsequent approvals shall be as provided in these land use chapters for approvals by the Planning Board.

All decisions of the Planning Board shall be final. In any case where the Planning Board has ruled favorably on an application, the Zoning Officer shall be directed to issue a zoning permit in accordance with the decision of the Planning Board, subject to any conditions as may be imposed thereon.
