In order for a site, structure or district to be zoned as a Design Review Overlay District, the Design Review Board shall first recommend to Council, the site, structure or district be designated as a Design Review District. The boundaries of the overlay district shall be shown on the District Map, and, in addition to regulations established in the underlying zoning district, all regulations set forth in this section shall also apply. Design Review Districts shall apply to both historic areas of Maumee and to more contemporary corridors and neighborhoods where urban design considerations are deemed to be particularly important and worthy of additional standards and review.
