Filing of approved plat. If the applicant desires to proceed with a subdivision for which final approval has been granted, he shall file with the county recording officer a plat map drawn in compliance with the New Jersey Map Filing Law (N.J.S.A. 46:23-9.9 et seq.), as amended and supplemented, within 95 days from the date upon which the plat was signed by the Planning Board Chairman and Secretary. The applicant shall, within one week after filing the subdivision with the City recording officer, notify, in writing, the City Engineer and City Tax Assessor of the date of filing of the subdivision with the City recording officer and the case and sheet or page number for the filed map. A duplicate tracing of the filed map indicating thereon the filing date shall be obtained from the City recording officer by the City Clerk, who shall distribute copies of the filed map to appropriate municipal officials. In the event the subdivider fails to so file within the period allowed, the approval of the plat shall expire unless, prior to expiration, such time is extended by the Board for a period not to exceed 95 days for good cause.
