Tar River at Princeville, North Carolina Flood Map Files from October 2016

Resource Abstract:
These polygon boundaries, inundation extents, and depth rasters were created to provide an extent of flood inundation along
the Tar River within the community of Princeville, North Carolina. The upstream and downstream reach extent is determined
by the location of high-water marks, not extending the boundary far past the outermost high-water marks. In areas of uncertainty
of flood extent, the model boundary is lined up with the flood inundation polygon extent. This boundary polygon was used to
extract the final flood inundation polygon and depth layer from the flood water surface raster file. The passage of Hurricane
Matthew through central and eastern North Carolina during October 7-9, 2016, brought heavy rainfall which resulted in major
flooding. More than 15 inches of rain were recorded in some areas. Over 600 roads were closed including Interstates 95 and
40, and nearly 99,000 structures were impacted by floodwaters. Immediately after the flooding, the U.S. Geological Survey
(USGS) documented 267 high-water marks (HWM), of which 254 were surveyed. The North Carolina Emergency Management documented
and surveyed 353 HWMs. The North Carolina Geodetic Survey documented and surveyed 12 HWM's in the community of Princeville.
Seven communities were mapped using Geographic Information Systems.

purpose:
These polygon boundaries, inundation extents, and depth rasters were created to support the development of flood inundation
maps for the Federal Emergency Management Agency's (FEMA) response and recovery operations following the October, 2016 Hurricane
Matthew flood event in the community of Princeville, North Carolina.
