<br />ABSTRACT <br /> <br />,is study evaluates quantitatively the economic, social and environmental <br />'fects of regulating the 100-year floodplain. Twenty-three case study <br />,mmunities were selected for analysis according to different locations, <br />,ood hazard types, community sizes, and economic conditions. <br /> <br />:fects of Flood plain regulations were evaluated by projecting development <br />.r 1980 and 1990 under three regulatory scenarios: (1) no regulations, allowing <br />1e free market to determine the 100-year floodplain use; (2) moderate regula- <br />lons similar to the current FIA regulations; and (3) stringent regulations <br />,rbidding new development and substantial improvements to existing structures <br />ld "correcting" past land use decisions which interfere with natural functions <br />E the 100-year floodplain. <br /> <br />oonomic Effects <br /> <br />,en no regulations are applied, average annual flood losses increase sharply <br />29% by 1980; 71% by 1990). Under moderate regulations, the losses in Scenario <br />would be decreased by 87% in 1980, and by 85% in 1990. Regulations that prevent <br />evelopment produce a small, but measurable absolute decline in average annual <br />lood losses (1% by 1990). <br /> <br />ocial Effects <br /> <br />ith no regulations, the total number of housing units in the 100-year floodplain <br />ould increase 13% by 1980 and 35% by 1990; population would increase in the <br />aO-year floodplain 12% by 1980 and 29% by 1990. <br /> <br />'ith moderate regulations, this increase in housing would be reduced by 37% in <br />980 and by 78% by 1990; the increase in population would be decreased by 43% <br />,n 1980 and 41% in 1990. With stringent regulations, housing units in the <br />,OO-year floodplain would decline 1% by 1980 and 6% by 1990. <br /> <br />:nvironmental Effects <br /> <br />1ith no regulations there would be a continuing, unlimited conversion of floodplain <br />'pen land to urban uses and additional 37% by 1990. Moderate regulations would <br />:educe this increase by 36% by 1990. Stringent regulations would not allow <br />lny further development of the floodplain, would begin to remove existing <br />levelopment, and would result in a 2(. reduction of developed acres. <br /> <br />Che study shows that moderate regulations will greatly reduce the rate of <br />lncrease of flood losses, but will not produce a decline of such losses. If <br />:he corrective elements of Scenerio III are added to the moderate regulations, <br />it is probable that the effects would closely approach the absolute decline <br />resulting from stringent regulations. Such a program would allow communities <br />to achieve their comprehensive community development goals, which allow them <br />to reduce their flood losses. It would also reduce national flood losses, as <br />envisioned in Federal legislation since 1936. <br />
