(A)   Over-all procedure for plat approval. The procedure for review and approval of a subdivision plat consists of two separate steps. The initial step is the preparation and the submission to the Planning Commission of a final plat together with the required certificates. This final plat becomes the instrument to be recorded in the office of the County Clerk when duly signed by the Secretary of the Planning Commission.
   (B)   Procedure for advisory meeting with the Planning Commission.
      (1)   Any owner of land lying within the area of jurisdiction of the Planning Commission who wishes to divide the land into two or more lots, sites or divisions for the purpose, whether immediate or future, of sale or building development, or who wishes to resubdivide for this purpose, shall submit a plan of the proposed subdivision to the Planning Commission for approval and shall obtain the approval prior to the filing of the subdivision plat for record. No plat of a subdivision of land within the area of planning jurisdiction shall be filed or recorded by the County Clerk without the approval of the Planning Commission as specified herein.
      (2)   In order to secure review and approval by the Planning Commission of a proposed subdivision, the prospective subdivider shall, prior to the making of any street improvements or installations of utilities, submit to the Planning Commission a preliminary sketch plat as provided in § 154.05 below, on approval of the preliminary sketch plat and other documents required in connection with the development.
