The provisions for this district shall apply to all floodplains for which regional flood data, as defined in § 143-34, is not available or where regional flood data is available but floodways have not been delineated. As adequate regional flood data becomes available and floodways are delineated for portions of this district; such portions shall be designated in the Flood-Fringe District or Floodway District, as appropriate.
Once it is determined according to § 143-19 that a proposed use is located within a floodway, the provisions of Article III shall apply. Once determined that the proposed use is located within the flood-fringe, the provisions of Article IV shall apply. All provisions of the remainder of this chapter apply to either district.

A.
Require the applicant to submit, at the time of application,

legal description of the property, fill limits and elevations, building
floor elevations and floodproofing measures.
