This information i~ <-.,. ~q' important to public agencies and private citizens concerned with future land developmentK. " f;t'/. The flood-prone areas have been delineated through U8e of readily availablp- information on past floods rather than from detailed field surveys and inspections. In general. the delineated areas are. for natural conditions and do not take into consideration the possible effects of existing or proposed flood control structures except where those effects could be evaluated. Flood areas have been iden- tified for: (1) urban areas where the upstream drainage basin exct:'eds 25 square miles. (2) tural areas in humid re){ionli where the upstream drainage basin exceeds 100 square milei'>. (~) rural areas in semiarid regions where the upstream drainagf' basin exceeds 250 square miles, and (4) smaller drainage basins, depending on topography and potential use of the flood plains. The 89th Congf('ss. in House Document 46.'). recommended the preparation of flood-prone area maps to assist in minimixinJo( flood losses by quickly identifying- the arf'as of potential flow hazards. More detailed flood information may he required for othrr purp()~cs such as structural designs, eco- nomic studies. or formulation of land-use rt.gulations. Such detailf"d information may he obtained from the U.s. Geological Survey. other Federal agenci~s..nr State. local. and private agencIes. 1978 c La Junta Gardens Well ,0 ." / 38000' 103"30' " . . .
