If the plan commission decides that the areas shown on a location map, or part thereof, may not be subdivided or disapproves a preliminary plan or final plan, the subdivider may file with the city clerk a petition to the city council for review of such decision of the plan commission, pointing out those parts of the decision to which the subdivider objects. In such event, a public hearing on the sufficiency or propriety of said location map, preliminary plan or final plan shall be conducted by the city council after notice thereof has been mailed by the city clerk at least one week before the hearing to the person or persons who requested the review; provided, however, that any matter which was the subject to a previous hearing before the city council in connection with the same proposed subdivision shall not be the subject of a second hearing.
After the conclusion of any such hearing, the city council may affirm or modify the order or decision of the commission, or approve the location map, preliminary plan or final plan. If a location map or preliminary plan is so approved by the mayor and city council, the subdivider shall proceed before the plan commission with the next step provided by this title. (1977 Code)
