Flood Hazards of Special Concern, NFIP/FEMA
Flood Hazards of Special Concern, NFIP/FEMA : "The mapping and regulatory standards of the NFIP are general standards and do not address every flood problem in the United States. Certain floodplains and flood-related hazards are less common, more destructive and harder to map than riverine, coastal, alluvial fan, and shallow flooding. Special hazards include coastal erosion, tsunamis, closed basin lakes, uncertain flow paths, dam breaks, ice jams, and mudflows". (FEMA, Flood Hazards of Special Concern, 2007)
