1. A "BP-4" District may be established on a Property in a single ownership or management control provided that:

a. An application for a change of zoning and a concept plan (hereinafter "Concept Plan") is approved by the Board.
b. A Site Plan in compliance with the conditions for rezoning and Concept Plan approved by the Board is submitted to the Commission and Board for approval and recorded with the Recorder of Deeds.
c. The schedule of construction is complied with in accordance with the approved rezoning ordinance and/or Site Plan approval.

2. A "BP-4" District may be established by the Board in the same manner that other Zoning Districts are established where the Board determines that any particular site should be developed accordingly, but because of possible conflicts with adjoining uses, more development control is necessary to protect the general welfare than is possible under the regulations of the "BP-1," "BP-2," and "BP-3" Districts.
3. The minimum Lot Area or combined Property area to establish a "BP-4" District shall be three (3) contiguous acres unless said property adjoins a "BP-4" District. For property adjoining an existing "BP-4" District, the minimum area is one (1) contiguous acre.
