(a) The area to be developed shall be at least three acres in area, in one ownership or under unified control; and
(b) A preliminary development plan showing a unified and well-organized arrangement of buildings, service facilities, parking areas and landscaping, and showing of driveways and streets planned so as to direct the least possible traffic onto local streets and to cause the least possible congestion on major secondary streets, shall be submitted to the Commission who may hold a public hearing thereon; and
(c) If approved, a final development plan shall be prepared and submitted for approval of the Commission before a building permit may be issued.
