The provisions for this district shall apply
to all floodplains for which flood profiles are not available or where
flood profiles are available but floodways have not been delineated.
Floodway and Flood-Fringe Districts shall be delineated when adequate
data is available.
Pursuant to § 251-20, it shall be determined whether the proposed use is located within a floodway or flood-fringe area. Those uses permitted in floodway (§ 251-11) and flood-fringe areas (§ 251-15) are allowed within the General Floodplain District, according to the standards of § 251-19, provided that all permits or certificates required under § 251-25 have been issued.

measures;
B.
Require the applicant to furnish any of the following
