(A) That the preliminary plat approval will remain in effect for a one (1) year period. The applicant may, during this period, submit all or part or parts of the preliminary plat for final approval. In the event that the subdivision is being developed in stages, the applicant may, by written mutual agreement with the County Board, have final approval of the last part of the plat delayed for a period not to exceed five (5) years from the date of the preliminary plat approval. Any part of a subdivision which is being developed in stages shall contain a tract of land at least one (1) block in area.

If the applicant does not submit the improvement plans prior to the submission of the final plat, then he shall submit the improvement plans to the Zoning Officer at the time that the final plat is submitted.
