An application for final approval may be for all the land included in a plan, or to the extent set forth in the preliminary approval, for a section thereof. The application shall include such drawings, specifications, covenants, easements, conditions and form of performance bond as were set forth by written resolution of the Planning Board at the time of preliminary approval. A public hearing on an application for final approval shall not be required provided the plan is in substantial compliance with the plan theretofore given preliminary approval. A public hearing shall be held if substantial modifications to the preliminary approval are proposed.

The municipal agency shall act on the final application within 45 days of the filing of a complete application.

A plan which has been given final approval shall be so certified by the chairman and secretary of the municipal agency and the Township Engineer and shall be filed on record forthwith in the office of the County Clerk before any development shall take place in accordance therewith.

In the event that a plan, or a section thereof, is given final approval and thereafter the developer shall abandon said plan or the section thereof, that has been finally approved and shall so notify the Planning Board in writing, or in the event the developer shall fail to commence the planned residential development within two years after final approval has been granted, then and in that event, such final approval shall terminate and be deemed null and void unless such time period is extended by the Planning Board upon written application of the developer.
