2,000 4,000 1,000 Feet 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 708.9 ft (216 m). The 100-year flood is 697 ft (212 m). 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.

Environmental Report for the EGC Early Site Permit Figure 2.3-15 Near Site Cross Section of Hydrogeologic Units and Piezometric Surfaces Legend Not to Scale NOTES:
- 1. Groundwater Levels indicated on the subsurface section were obtained by interpolating between borings with piezometers. Information on actual groundwater levels exist only at boring locations with piezometers.
It is possible that groundwater levels between borings with piezometers may vary from those indicated.
- 2. The depth and thickness of soil and rock strata indicated on the subsurface section were obtained by interpolating between borings. Information on actual soil and rock conditions exist only at boring locations.
It is possible that soil and rock conditions may vary from those indicated.
- 3. The discussion in the text is necessary for proper understanding of the nature of the subsurface materials
- 4. Elevations refer to the USGS Datum Southwest Northeast
