There i!:'. on the average, about 1 chance in 100 that the desi~natt'd areas will be inundated in any year. This information is important to public ageneies and private citizens concerned with future land dt'velopments. The flood.prone artlas havp bt'en delineated through use of readily available informa- tion on past floods rather than from detailed field surveys and inspections. In general. the delint"ated areas are for natural conditions and do not take into con:;ideration the pos- :;ible efft'cts of existinit or proposed flood control structurf."S except whert> those effects could t)f> e\"aluated_ Flood area~ ha\'f~ been identified for: (1) urhan areas where the up- stream drainagt' hasin exceeds 25 ~quare milt's, (2) rural areas in humid regions where tht> upstream drainage ha}iin ext't'eds 100 ::;quare miles. C~) rural areas in semiarid rel'rions where the upstream drainagt. basin exceeds 2:,0 square mih'l'l. and (4) smaIlt'r drainage basins, depending on topognph..,. and potential use of the flood plains. The 89th Congress. in House Documt'nt 40.5. ft'(:ommencled the preparation of f1ood-pronp an-a maps to assist in minimizing flood lO!'lses hy quickly identi(ying the areas of potential flood hazards. More detailed flood information may he required for other purposes such as structural designs. economic studies. or formulation of land.use regulations. Such d(>- tailed information may be obtainE'd from the U.S. Geological Survey, other Federal agenci{'s, or State, local. and private agencies. 9 L-LJ\ i 7 , ' I, ~ ~..
