<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 deJineated 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 the pas.
<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 wh~re the up.
<br />stream drainage basin exceeds 25 square miles, (2) rural areas in humid regions'where the
<br />upStream drain~ basin exceeds 100 square miles, (3) rural areas in semiarid reg\ons 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 />The 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
