In order to obtain a building permit in a planned residence district, the developer must prepare a development plan or plans as the Commission and City Council may approve. The Commission and the City Council may approve generalized concepts for the entire tract and require a more detailed development plan as phases of the project are submitted in accordance with the development schedule. The development plan may be submitted with preliminary or final plats which may be needed, or may be submitted separately if the requirements of Title D, Chapter 1 have been met. The development plan shall be submitted and approved by the commission and the City Council in the same manner as final plats as specified in Title D, Chapter 1, §§ 11.00 through 15.00. The development shall contain those items listed in § 30.00 of this chapter which the Commission or City Council may deem necessary. The development plan shall be filed with an appropriate application form and fee of $50. The developer will also reimburse the city for any review made by the City Engineer. The Commission shall record in its minutes where the development plan makes appropriate use of the flexibility possible in this zone.
