MapFldHazAr is a GIS shapefile representing the area within the flood mapping boundaries defined by the engineering models for the 100 year, 500 year and floodway. The MapFldHazAr spatial table contains information about the flood hazard within the study area. These zones are used by FEMA to designate the Special Flood Hazard Area (SFHA), identify areas of coastal high hazard flooding, and for insurance rating purposes. These data are the flood hazard areas that are or will be depicted on the FIRM.
These data were collected and derived by the North Carolina Floodplain Mapping Program (www.ncfloodmaps.com) as part of its effort to modernize FEMA Flood Insurance Rate Maps (FIRM) statewide. The North Carolina Floodplain Mapping Program was established through a Cooperating Technical State (CTS) agreement with FEMA in response to the extensive damage caused by Hurricane Floyd in 1999.
