The North Carolina General Assembly authorized the North Carolina Geological Survey (NCGS) to produce landslide hazard maps for 19 western counties in response to the number of slope movements (landslides) and destruction caused by the remnants of Hurricanes Frances and Ivan in western North Carolina in September 2004. The intent of the landslide hazard mapping program is to provide the public, local government, and local and state emergency agencies with a description and location of areas where slope movements have occurred, or are likely to occur, and the general areas at risk from these slope movements. The locations of previous slope movements are important because slope movements often reoccur in the same general areas. This mapping is not intended to be a substitute for a detailed, onsite analysis by a qualified geologist or engineer.
The slope movement hazard map series for Buncombe County consists of three folded maps designed to be used in conjunction with each other; (North Carolina Geological Survey Geologic Hazards Map Series 4 (NCGS GHMS-4, Sheets 1, 2, and 3)). NOTE: These maps will be printed from an inkjet plotter; the maps may fade over time.
