The UTDD of Downingtown Borough shall be deemed an overlay district on the otherwise applicable zoning districts as delineated on the Borough Zoning Map. Said overlay shall become affixed to the land as the base zoning for the UTD tract, as defined in §
287-69.12B below (and the Official Zoning Map of the Borough shall be amended accordingly) upon the approval by the governing body of an application for a zoning map change (map change application); provided, however, that in the event that the construction of the transportation center as provided in the approved UTD plan and as required by §
287-69.13C has not been completed within five years of the approval of the map change, or if the applicant or its successor notifies the Borough in writing that it does not intend to so complete such construction, the zoning of the UTD tract shall revert to the zoning that existed immediately prior to the approval of the map change, and the map change shall be of no further force or effect. For so long as the overlay district is affixed to the UTD tract as provided herein, all general standards and regulations, standards and regulations relating to a particular use permitted by this Article
XVB and standards and regulations applying to any underlying zoning district provided elsewhere in this chapter shall continue to apply to such use or underlying district, as the case may be, except as modified by this Article
XVB. No map change application shall be considered complete until such time as the applicant has agreed to deposit with the Borough financial security [in accordance with the provisions of Chapter
256, Subdivision of Land (SLDC)] or has provided evidence of public funding in an amount sufficient to cover the cost of all off-site improvements shown on the UTD plan. No building permit for the second phase of development within the UTDD shall be issued prior to the issuance of a certificate of occupancy for the transportation center required by §
287-69.13C and as provided in the UTD plan and the offer for dedication or conveyance of the roads as provided in the UTD plan.
