A. 
The final plat and supporting material for the proposed subdivision constitute the complete submission of the subdivision proposal and include the recommendations resulting from Planning Board review of the preliminary plat and public hearing held thereon, as well as a review of the detailed layout drawings for the public improvements. In accordance with § 276 of the Town Law, as amended, the Planning Board may waive a public hearing on the final plat when the final plat substantially conforms to an approved preliminary plat on which a public hearing has been held. After final plat approval by the Planning Board, this complete submission becomes the basis for the construction of the subdivision. The plat itself must be recorded at the office of the County Clerk and the Town Clerk to have legal status. If the final plat will be filed with the County Clerk in more than one section, the approved final plat of the entire subdivision will be filed with the Town Clerk.
B. 
The final plat shall be an accurate survey of the properties resulting from the subdivision.
