c. Whenever an application for development requests relief pursuant to subsection b. of this section, the board of adjustment shall grant or deny approval of the application within 120 days after submission by a developer of a complete application to the administrative officer or within such further time as may be consented to by the applicant. In the event that the developer elects to submit separate consecutive applications, the aforesaid provision shall apply to the application for approval of the variance. The period for granting or denying any subsequent approval shall be as otherwise provided in this act. Failure of the board of adjustment to act within the period prescribed shall constitute approval of the application, and a certificate of the administrative officer as to the failure of the board of adjustment to act shall be issued on request of the applicant, and it shall be sufficient in lieu of the written endorsement or other evidence of approval herein required, and shall be so accepted by the county recording officer for purposes of filing subdivision plats. Whenever review or approval of the application by the county planning board is required by section 5 of P.L. 1968, c. 285 (C. 40:27-6.3), in the case of a subdivision, or section 8 of P.L. 1968, c. 285 (C. 40:27-6.6), in the case of a site plan, the municipal board of adjustment shall condition any approval that it grants upon timely receipt of a favorable report on the application by the county planning board or approval by the county planning board by its failure to report thereon within the required time.
An application under this section may be referred to any appropriate person or agency for its report; provided that such reference shall not extend the period of time within which the zoning board of adjustment shall act.
