It is intended that PUD development review will be a two-stage process, first involving Preliminary Development Plan approval to include amendment to the Zoning Map designating the parcel a PUD Overlay District, and then involving Final Development Plan approval, which includes Subdivision Preliminary Plat approval. Applicants are encouraged to separately submit applications for approval of Preliminary Development Plans to the Planning Commission for review before extensive engineering and formal submission of a Final Development Plan as set forth in the following sections. At the applicant's option, however, the applicant may proceed directly toward filing of a Combined Preliminary and Final Development Plan. The procedures for a Combined Preliminary and Final Development Plan shall require the same procedural manner as an amendment to this Zoning Code in accordance with Chapter 1105.08 (Public Hearing Requirements). The submission requirements shall include all requirements for a Preliminary Development Plan and a Final Development Plan.
