(1) Detailed Plans. After the approval of the application and general plans, the applicant shall file detailed plans for review by the planning and zoning commission, showing the details of the proposed development as fully as possible, and including elevations and perspectives of proposed construction. If the applicant later wishes to change any of the details of the proposed development, further detailed plans shall be filed for review by the planning and zoning commission. No building permit for the proposed development or any part thereof shall be issued until the planning and zoning commission has determined that the pertinent detailed plans are in accordance with the application and general plans as approved and with the intent stated in IGCC 17.15.010. If any detailed plans are not acted upon by the planning and zoning commission within 60 days after they are submitted to it, they shall be deemed to be approved.

(2) Plans Filed. Within three months after the approval of the application and general plans, a certified copy of such application and general plans shall be filed by the applicant at his or her own expense in the office of the city administrator.

(3) Time of Completion. If construction of improvements is not begun and diligently prosecuted to completion within a reasonable time established by the planning and zoning commission at the time of approval of detailed plans, and if an extension of time is not given by the planning and zoning commission for good cause shown, then the modifications or amendments of this chapter provided for in IGCC 17.15.040 shall become null and void and the tract shall revert to all the requirements of its previous zoning. No certificate of zoning compliance shall be issued until a detailed report is submitted by the applicant to the planning and zoning commission showing the outcome of construction and the planning and zoning commission certifies that all requirements of this section relating to planned developments have been met.
