(A) Purpose and intent. To establish and maintain districts that overlay existing zoning district in order to better manage significant areas with specific needs that cross zoning district boundaries, such as encouraging growth in areas with existing public facilities or preserving areas with valued resources and amenities. All sites within an overlay district shall continue to bear their original zoning, but shall also comply with the provisions of the overlay district appended.
(B) Boundaries. The boundaries are established based on district-specific criteria and may not be aligned with roads, lot lines or other human-made boundaries. The boundaries shall be designated on official overlay maps. Overlay maps are considered part of the Official Zoning Map and are, therefore, approved and amended following the procedures in §§ 152.010 through 152.014 of this chapter.
(C) Permits. No subdivision, rezoning, reconstruction, alteration or addition shall be made to any existing structure, nor shall any additional structure be constructed upon a site in any overlay district, except in accordance with the provisions of the applicable overlay district.
(D) Districts. The following overlay districts are hereby established:
(1) Floodplain Overlay Districts:
(a) Floodway District (FW);
(b) Flood Fringe District (FF); and
(c) General Floodplain District (GF).
(2) Mississippi Headwaters Overlay District (MH);
(3) Shoreland Overlay District (SH); and
(4) Airport Zoning Overlay District (AP).
(E) Supremacy. If a provision of an overlay district conflicts with a provision or provisions of the underlying zoning district, the more restrictive provision shall apply.
