There is, on the avt'Tage, about 1 chanc(> in 100 that the designated areas will be inundated in any year. This information is important to public agencips and private citizens concernt>d with future land developments. The flood-prone areas have be~n delineated through use of readily available information on past floods rather than from detailed field surveys and inspections. In gE'neral, the delineated areas are for natural conditions and do not take into consideration the possible effects of existing or proposro flood control structures except where those effects could be evaluated. Flood areas have been inen~ tified for: (1) urban areas where the upstream drainage basin exceeds 25 square- mile-s, (2) rural areas in humid regions where the upgtream drainage basin exceros 100 square miles, (3) rural are-as in semiarid regions where the upstream drainage basin exceeds 250 square miles, and (4) smallel' drainage basins, depending on topography and potential use of the flood plains. The 89th Congress, in House Document 465. recommended the preparation of flood~pl'one an'a maps to assist in minimizinJit flood losses by Quickly identifying the areas of potential flood hazards. More detailed flood information may be required for other purposes such as structural designfl. eco- nomic studies, or formulation of land-use regulations, Such detailed information may be obtained from the U.S. Geological Survey, otht>r Federal agencies. or State, local, and private agencies. .-!
