§ 152.40  PRELIMINARY PLAT.
   (A)   Procedure.
      (1)   Approval of the Planning Commission.
         (a)   The subdivider-developer shall engage a qualified land planner, registered land surveyor or engineer to prepare a preliminary plat of the area to be subdivided.
         (b)   The subdivider-developer shall review proposed utility easements with utility companies and submit letters thereof from each company.
         (c)   The subdivider-developer shall submit ten or more copies of the preliminary plat to the City Administrator, at least seven days prior to the Planning Commission meeting for initial consideration. The subdivider-developer shall include a written statement along with the preliminary plat describing the proposed subdivision. The written statement shall include the anticipated development schedule, a table showing total number of lots and sizes, utilization of existing natural features and vegetation and the like.
         (d)   The City Administrator shall submit one copy of the preliminary plat to the Planning Commission, one copy to the Engineer, one copy to the County Engineer if the plat borders a county road, one copy to the District Engineer of the state’s Highway Department if the plat borders a federal, state or state-aid highway and one copy to the county’s Zoning Administrator.
         (e)   All agencies receiving copies of the preliminary plat shall transmit a report of their reaction together with any supporting material to the Planning Commission prior to the meeting at which such plat is to be considered. The subdivider-developer shall be required to pay the cost of the services.
         (f)   The Planning Commission may require qualified technical and staff review of the preliminary plat regarding general planning; conformity with the plans of other private and public organizations and agencies; adequacy of proposed water supply, sewage disposal, drainage and flood control; special assessment procedures and other features. The subdivider-developer shall be required to pay the cost of the services.
         (g)   The Planning Commission shall hold a public hearing on the preliminary plat within 45 days of its filing date, and the City Administrator will public notice of the time and place thereof in the official newspaper and send notice to property owners abutting the exterior boundary of the proposed plat. Notices will be made at least ten days prior to the day of the hearing. A Planning Commission meeting may serve as a public hearing provided the legal requirements pertaining to the same are met.
         (h)   At the public hearing, the subdivider-developer and all interested persons shall have the opportunity to be heard. The Commission shall then prepare a report recommending approval, disapproval or approval with conditions and submit it to the Council along with a copy being sent to the subdivider-developer within 15 days of the public hearing. In case the plat is disapproved, the subdivider shall be notified of the reason for such action and what requirements will be necessary to meet the approval of the Planning Commission.
      (2)   Approval of the Council. After review and approval of the preliminary plat by the Planning Commission, the preliminary plat, together with the recommendations of the Planning Commission, shall be submitted to the Council for consideration. Approval or disapproval of the preliminary plat will be conveyed to the subdivider in writing within ten days after the meeting of the Council at which the plat was considered. In case the plat is disapproved, the subdivider shall be notified of the reason for the action and what requirements will be necessary to meet the approval of the Council. 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 final plat. This approval of the preliminary plat shall be effective for a period of two years, unless an extension is granted by the Council. The subdivider may file a final plat limited to the portion of the preliminary plat which he or she proposes to record and develop at the time; provided that, the portion must conform to all requirements of this chapter. If some portion of the final plat has not been submitted for approval within this period, a preliminary plat must again be submitted to the Planning Commission and the Council for approval.
