  Developed by the Federal Emergency Management Agency, these maps describe areas subject to 100 and 500 year flooding.  Flood prone areas are indicated by shading.  The designations were made during the 1970’s and the maps were printed during the 1980’s. The scales range from 1:1,000 to 1:2,000.  Features include place names, rivers, streams, drainage ditches, highways, dirt roads, and railroads. The collection owns nearly 1,000 of these maps covering 33 eastern North Carolina counties.
