J. Approval or disapproval of the preliminary plat will be conveyed to the subdivider in writing within five (5) days after the meeting of the planning and zoning board at which such plat was considered. In case the plat is disapproved, the subdivider shall be notified of the reasons for such action and what requirements will be necessary to meet approval of the planning and zoning board. The approval of the preliminary plat does not constitute an acceptance of the subdivision, but is deemed to be an authorization to proceed with the preparation of the final plat. This approval of the preliminary plat shall only be effective for a period of one year, unless an extension is granted by the planning and zoning board. If the final plat has not been submitted for approval within this period, a preliminary plat must again be submitted to the board for approval. (1991 Code § 20-43)
