<br />Approximate houndarie~ of flood-prone areas are shown on this map. There is. on the
<br />avt.'rage, about 1 chance in 100 that the designated areas will b(> inundated in any year.
<br />This information is important to public agencies and llrivat\~ citizens concerned with future
<br />land developments.
<br />The floon-prone areas have lwen delineated through use of readily available informa-
<br />tion on past floods rather than from detailed field surveys and inspections. In general,
<br />the delinpated areas are for natural conditions and do not take into consideration the pos-
<br />siblf' ('ffects of exist.ing or proposed flood control structures except where those effects
<br />could bp evaluated. Flood areas have been identified for: (1) urban areas where the up-
<br />!oltream drainage basin exceed~ 2;) square miles, (2) rural areas in humid regions where the
<br />upstream draina~e basin exceeds 100 square miles, (3) rural areas in semiarid regiuns where
<br />the upstream drainagt' basin exceeds 250 square miles, and (4) smaller drainage basins,
<br />depending on topugrllphy and JXltential tlst' of the flood plains.
<br />The 89th Congre::>l:>, in HOUSt~ Document 465, recommf'nded the preparation of f1oon-prone
<br />ar(>a maps to assist in minimizing flood losses by quickly identifying the areas of potential
<br />flood hazards. More detailed flood information may be required for other purposes such
<br />a~ stru('tural deRigns, economic !-Itudies. or formulation of land~use regulations. Such d(-'-
<br />tailed information may be obtained from the U.S. Geological Survey, other Federal agencies.
<br />or State, local, and private agf'ncies.
