tion on past floods rather than from detailed field surveys and inspectionH. In general.
the delineated areas are for natural conditions and do not take into consideration the po..~.
sible effects of existing or proposed flood. control structures except where those effects
could be eyaluated. Flood areas have been identified for: (1) urban areas where the up-
stream drainage basin exceeds 25 square miles. (2) rural areas in humid regions where the
upstream drainage ba.qin exct;'t;'dH 101) square miles, (:1) rural areas in semiarid regions where
the upstream drainage basin exceeds 250 square miles, and (4) smaller drainage basins.
depending on topography and potential use of the flood. plains.
The 89th Congress. in House Document 465. recommended the preparation of flood-prone
area maps to assist. in minimizing flood losses by quickly identifying the areas of potential
flood hazards. More detailed flood information may be required for other purposes such
as structural designs, economic studies, or formulation of land-use regulations. Such de-
ulilt.d information may be obtained from the U.s, Geological Survey, other Federal agencies,
or Statt.>, local, and private agencies.
