"Floodplain management regulations" mean zoning <br />ordinances, subdivision regulations, building codes, health <br />regulations, special purpose ordinances (such as a <br />floodplain ordinance, grading ordinance, or erosion control <br />ordinance) and other applications of police power. The <br />term describes such state or local regulations, in any <br />combination thereof, which provide standards for the <br />purpose of flood damage prevention and reduction. <br /> <br />16. "Flooded area map" means a drawing which shows in plan <br />view the horizontal boundary of floods of various <br />magnitudes or frequencies. Such maps include, but are not <br />limited to, Flood Hazard Boundary Maps (FHBM) and Flood <br />Insurance Rate Maps (FIRM) published by FEMA, Floodprone <br />Area Maps published by the U.S. Geological Survey (USGS), <br />Flooded Area Maps published by the Corps of Engineers <br />(CDE), Flood Hazard Area Maps published by the U.S. Soil <br />Conservation Service (SCS), Flooded Area Maps published by <br />the Board, and Flood Hazard Area Delineations (FHAD) <br />published by the Urban Drainage and Flood Control District <br />(UD&FCD). <br /> <br />17. "Foreseeable development" means the potential future <br />development of, or changes in, the land uses that are <br />likely to take place during the period of time covered by a <br />community's adopted master land use plan, or over a 20-year <br />period, whichever is longer. <br /> <br />18.

"HEC-2" means the most recently re'lised version of the <br />computer program developed by the U.S. Army Corps of <br />Engineer's (CDE) Hydraulic Engineering Center (HEC) for <br />calculating f100d water surface elevations. <br /> <br />-4- <br />
