Probable Maximum Flood Zone Boundary (709.8 ft)
Note: The Probable Maximum Flood Zone Boundary and the 100-year Flood Zone Boundary
were derived form USGS National Digital Elevation Model Data. The Probable Maximum
Flood Elevation is 709.8 ft (216m). The100-year flood is 697 ft (212m). Variations in
mapping accuracy between the map base and the flood boundaries derived from the
USGS Digital Elevation Model are apparent in locations on the map.
