The subdivider shall file with the City Clerk an application for preliminary approval, together with as many copies of the complete proposed plat as Council may by resolution require according to the provisions of these Subdivision Regulations. The preliminary plat shall be examined by both the City Attorney and the City Manager within one week after filing in order to determine that the proposed plat is in full compliance with the formal and technical provisions, respectively, of these Regulations. The City Attorney and the City Manager shall endorse the application for preliminary approval with their individual findings and return it to the City Clerk for appropriate action. If the preliminary plat is not approved by either the City Attorney or the City Manager, or both, the subdivider shall be immediately so notified by the City Clerk so that he or she may take necessary corrective action. The refiling of such a corrected preliminary plat shall be done in the same manner as was the original filing as provided herein, except that no filing fee shall be required if the refiling occurs within sixty days of receipt of notice from the City Clerk.
