_Cape Fear River and Other Major Hydrography
Waterbodies
QFour Counties Boundary
Surrounding North Carolina County
Notes:
1. The river buffer includes (i) the extent of the 100-year floodplain associated with
Cape Fear River as provided by the Federal Emergency Management Agency
(FEMA); (ii) the limits of saltwater marshes in the areas where Black River and
Northeast Cape Fear River meet Cape Fear to account for the possibility of tidal
backwash of Cape Fear River into these rivers; and (iii) the last half mile floodplain
of each tributary before it joins the Cape Fear River.
2. County boundaries and major hydrography waterbodies were downloaded from
NC OneMap site (https://www.nconemap.gov).
3. Basemap source: Esri, HERE, Garmin, (c) OpenStreetMap contributors, and the
GIs user community.
