No subdivision or part thereof shall be considered where results of said percolation tests do not meet the established requirements of this chapter or other applicable ordinances or regulations, nor shall any subdivision or part thereof be considered where other physical characteristics of the land would cause septic conditions unsanitary to the public or contrary to the requirements of this chapter or other applicable ordinances or regulations.

The Planning Board shall grant final approval if the detailed drawings, specifications and estimates conform to the standards established by ordinance for final approval, the conditions of the preliminary approval and the standards prescribed by the Map Filing Law, N.J.S.A. 46:23-9.9 et seq.

Final approval shall be granted or denied within 45 days after submission of a complete application to the Board Secretary or within such further time as may be consented to by the applicant. Failure of the Board to act within the period prescribed shall constitute final approval, and a certificate of the Board Secretary as to the failure of the Board to act shall be issued on request of the applicant, shall be sufficient in lieu of written endorsement or other evidence of approval and shall be so accepted by the County Clerk for purposes of filing subdivision plats.

Whenever review or approval by the County Planning Board is required, local approval shall be conditioned upon timely receipt of a favorable report from the County Planning Board or its failure to report thereon within the required time period.

The zoning requirements and all other rights applicable to the preliminary approval, whether conditional or otherwise, shall not be changed for a period of two years, provided that if the standards prescribed for final approval have been followed, the Planning Board may extend the period of protection for periods of one year not to exceed three extensions. Final approval terminates the time period of preliminary approval for the section involved.

In the case of 25 acres or more, these rights may be granted for a longer period of time, taking into consideration the number of dwelling units and nonresidential floor area permissible, economic conditions and the comprehensiveness of the development. Thereafter an extension of final approval may be granted for such additional periods of time as reasonable, taking into consideration:

The final plat shall show or be accompanied by the following:

Prior to the hearing, copies of the plat shall be forwarded by the Board to the following:

Final approval shall expire 95 days from the date of signing of the plat, unless within that period the plat shall have been duly filed by the developer with the County Clerk. The Planning Board may, for good cause shown, extend the period for recording for an additional period not to exceed 190 days from the date of signing of the plat.

No subdivision plat shall be accepted for filing by the County Clerk until it has been approved by the Board as indicated by the signature of the Chairman and Secretary of the Board or a certificate has been issued regarding failure to act within the required time period. The signatures of the Chairman and Secretary of the Board shall not be affixed until the developer has posted the guarantee as required under this article. If the County Clerk records any plat without such approval, such recording shall be deemed null and void, and on request of the Borough the plat shall be expunged from the official records.

It shall be the duty of the County Clerk to notify the Planning Board, in writing, within seven days of the filing of any plat, identifying the instrument by its title, date of filing and official number.
