<br />Approximate boundaries of flood-prone areas are shown on this map. There is, on the
<br />average, about 1 chance in 100 that the designated areas will be inundated in any year.
<br />This information is important to public agencies and private citizens concerned with future
<br />land developments.
<br />The flood-prone areas have been delineated through use of readily available infonna-
<br />tion on past floods rather than from detailed field surveys and inspections. In general.
<br />the delineated areas are for natural conditions and do not take into consideration tbe pos-
<br />sible effects of existing or proposed flood control structures except where those effects
<br />could be evaluated. Flood areas have been identified for: (1) urban areas where the up-
<br />stream drainage basin exceeds 25 square miles. (2) rural areas in humid regions where the
<br />upstream drainage basin exceeds 100 square miles, (3) rural areas in semiarid regions where
<br />the upstream drainage basin exceeds 250 square miles. and (4) smaller drainage basins,
<br />depending on topography and potential use of the flood plains.
<br />Tbe 89th Congress. in House Document 465, recommended the preparation of flood...prone
<br />area 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 />as structural designs, economic studies, or formulation of land-use regulations. Such de-
<br />tailed information may be obtained from the U.S. Geological Survey. other Federal agencies.
<br />or State. local, and private agencies.
