When the Planning Board renders final approval of a Class B regional subdivision, the Board shall issue a permit authorizing the subdivider to undertake the subdivision in accordance with any terms and conditions set forth therein. The Planning Board, in conjunction with its approval of any Class B regional subdivision, may impose such requirements and conditions as are allowable within the proper exercise of the police power, including the restriction of land against further development of principal buildings, whether by deed restriction, restrictive covenant or other similar appropriate means, to ensure that guidelines as to intensity of development as provided in the Zoning Law shall be respected, and the imposition of reasonable conditions to ensure that the subdivision will be adequately supported by services and improvements made necessary thereby and to ensure that the subdivision will be completed in accordance with the terms of the approval and permit.
