(A)   Purpose.  The purpose of the preliminary plat is to provide an interim step in the procedure at which point the subdivider shall present drawings of the detail features of the subdivision. It is at this point that the items discussed at the sketch plat stage and as set down herein are prepared in a form from which determinations can be made as to the technical workability of the development proposal.
   (B)   After the Planning Commission has approved the sketch plat, the subdivider may proceed with the preparation of the preliminary plat. After the subdivider has prepared the preliminary plat, he or she may take either of the following actions:
      (1)   He or she may present the preliminary plat and preliminary plat checklist to the Planning Commission and obtain approval thereof before proceeding with preparation of the improvement plans; or
      (2)   He or she may present the improvement plans and improvement plans checklist to the Planning Commission at the time the preliminary plat and preliminary plat checklist are presented.
   (C)   Whenever the subdivider presents to the Planning Commission a preliminary plat and preliminary plat checklist, without improvement plans, the Planning Commission may conditionally approve the preliminary plat, subject to Planning Commission approval of the improvement plans within six months following the preliminary plat conditional approval.
   (D)   After review of the preliminary plat, the Planning Commission shall, within 60 days of its submission, approve, conditionally approve or reject the plat. The subdivider shall be notified in writing of this action, together with any conditions of approval or the reasons for rejection.
   (E)   Whenever the subdivider presents to the Planning Commission the preliminary plat, preliminary plat checklist, improvement plans and improvement plans checklist and the Planning Commission finds that the plat and improvement plans meet all the requirements of these regulations, it shall approve the preliminary plat and improvement plans by placing a certificate of approval upon each copy of the plat and plans. Such certificate of approval shall bear the signature of the Chairperson and Secretary of the Planning Commission and shall provide that the approval given thereby does not constitute approval for purposes of recording.
   (F)   Approval of the preliminary plat shall not in all cases entitle the subdivider to approval of the final plat. Upon preliminary approval, if any conditions arise which would cause the preliminary plat to become unsatisfactory due to health, safety or welfare of the community, the Planning Commission shall recommend that the final plat be rejected.

      (6)   Effect of approval.  Approval of a preliminary plat by the Planning Commission constitutes authorization for the City Engineer to release construction plans subject to his or her final approval and for the City Engineer to authorize for the property owner to commence grading of the site and construction of such public improvements as are required by the Planning Commission. Approval of a preliminary plat also authorizes the property owner, upon fulfillment of all requirements and conditions of approval, to submit for approval an application for final plat approval. Upon release of the construction plans, the City Engineer may, upon request of the applicant, issue a certificate indicating the construction plans have been released and construction of the improvement is thereafter authorized. Additional certificates may be issued by the City Engineer authorizing the construction of private utilities on a phased schedule. The certificate shall read as follows:
“The preliminary plat for (insert name of the subdivision or addition) as approved by the City of Durant Planning Commission on (insert date of approval) is authorized for use with engineering plans for the construction of public improvements as approved by the City Engineer. A final plat shall be approved by the Planning Commission upon the completion of all public improvements or the provision of a subdivision improvement agreement under the terms of the Subdivision Ordinance and submission of a final plat in compliance with Section 3.6 of the Subdivision Ordinance of the City of Durant.
Zoning regulations that affect exterior appearance of a single-family house or the landscaping of a single-family lot and that are adopted after approval of a preliminary plat for a single-family residential development, shall not apply for a period of two years from the latter of the date of plat approval or the date of the acceptance of public improvements related to the plat."
