<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Surface Water Resource Protection Areas consist of : (1) the areas which drain on the surface or underground to existing public water supply reservoirs, (2) the land surfaces in the Flood Plain upstream of an approved public water supply intake. The Flood Plain is comprised of the 100-year Flood Plain as defined in Article 33 of New Castle County Unified Development Code and (a) delineated by the Federal Emergency Management Agency (2010) and (b) soils frequently and very frequently flooded mapped by the New Castle County Soil Survey, prepared by the U.S. Department of Agriculture, Natural Resources Conservation Service (2010), and (3) Erosion Prone Slopes contiguous to and draining toward a Flood Plain or a water course upstream of an approved public water supply intake. Erosion Prone Slopes consist of soils with all or part of the area at greater than or equal to 15% slopes as mapped by the New Castle County Soil Survey, prepared by the U.S. Department of Agriculture, Natural Resources Conservation Service (2010) with map unit symbols BkD, BnF, BrvF, CnD, GaC, GaD, GaE, GeC, GgC, GgD, GhC, GnC, MaC, MaD, MaE, MxC, NtC, NvC, NvD, NvE, SaD, SaE, and UzF.</SPAN></P><P><SPAN>Surface water sources are susceptible to pollutants released in proximity to and upstream of intakes or storage facilities. Currently, these sources provide approximately 70% of the daily public water supply and most of the emergency water supply for New Castle County. The drainage areas, flood plains, and erosion prone slopes were derived from the following maps and report: (1) U. S. Geological Survey Topographic Quadrangle maps, (2) WATER 2000, Volume VII, 1984, Water Resources Agency for New Castle County (1984), (3) Digital Flood Plain Mapping, Federal Emergency Management Agency (2010), and (4) New Castle County Soil Survey, U. S. Department of Agriculture, Natural Resources Conservation Service (2010).</SPAN></P></DIV></DIV></DIV> |
