(A) Basis of districts. The various floodplain districts shall include special flood hazard areas. The basis for the delineation of these districts shall be the Flood Insurance Study (FIS) and the Flood Insurance Rate Maps for the Town of Brookneal prepared by the Federal Emergency Management Agency, Federal Insurance Administration, dated August 28, 2008, as amended.
(1) The Floodway District is delineated, for purposes of this chapter, using the criterion that certain areas within the floodplain must be capable of carrying the waters of the 100-year flood without increasing the water surface elevation of that flood more than 1 foot at any point. The areas included in this District are specifically defined in Table 2 of the above-referenced Flood Insurance Study and shown on the accompanying Flood Boundary and Floodway Map or Flood Insurance Rate Map.
(2) The Flood-Fringe District shall be that area of the 100-year floodplain not included in the Floodway District. The basis for the outermost boundary of the District shall be the 100-year flood elevations contained in the flood profiles of the above-referenced Flood Insurance Study and as shown on the accompanying Flood Boundary and Floodway Map or Flood Insurance Rate Map.
(3) The Special Floodplain District shall be those areas identified as either an AE Zone or A1-30 zone on the maps accompanying the Flood Insurance Study for which 100-year flood elevations have been provided but for which no floodway has been delineated.
(4) The Approximated Floodplain District shall be those areas identified as an A or A99 Zone on the maps accompanying the Flood Insurance Study. In these zones, no detailed flood profiles or elevations are provided, but the 100-year floodplain boundary has been approximated.
(B) Overlay concept.
(1) The Floodplain Districts described above shall be overlays to the existing underlying districts as shown on the Official Zoning Ordinance Map, and as such, the provisions for the floodplain districts shall serve as a supplement to the underlying district provisions.
(2) If there is any conflict between the provisions or requirements of the Floodplain Districts and those of any underlying district, the more restrictive provisions and/or those pertaining to the floodplain districts shall apply.
(3) In the event any provision concerning a Floodplain District is declared inapplicable as a result of any legislative or administrative actions or judicial decision, the basic underlying provisions shall remain applicable.
