are nearby sites which likely receive groundwater migration from beneath the Site. CES estimates
that depth to shallow groundwater is within 30-feet of the ground surface.
Considering the surface topography for the Site, as interpreted from the USGS topographic
Skyland, North Carolina quadrangle map, local groundwater is expected to follow topography and
flow to the southeast away from the Site. Factors such as underground structures, seasonal
fluctuations, soil and bedrock geology, production wells, and other factors beyond the scope of this
study often locally influence actual groundwater flow direction. The actual groundwater flow under
the Site can only be accurately determined by performing a hydrogeologic study, which is beyond
the scope of this project. Estimated groundwater levels and/or flow direction(s) may vary due to
seasonal fluctuations in precipitation, local usage demands, geology, underground structures, or
dewatering operations.
5.2.5 Other Physical Setting Sources
Flood Plain Map
According to information supplied by GeoPlus Physical Settings Maps from GeoSearch
(GeoSearch 2019b) for the FEMA Flood Insurance Rate Map (FIRM) for the Site and surrounding
areas (panel number 3700869400J dated May 18, 2018), the Site is located within FEMA Zone X,
which is defined as follows:
• Zone X - is described as areas outside the 1-percent annual chance floodplain, areas of 1%
annual chance sheet flow flooding where average depths are less than 1 foot, areas of 1%
annual chance stream flooding where the contributing drainage area is less than 1 square mile,
or areas protected from the 1% annual chance flood by levees.
A copy of the GeoPlus Physical Settings Maps is provided as Appendix J.
Wetlands Map
According to a review of the United States Fish and Wildlife Service (USFWS) National Wetlands
Inventory (NWI) database (http://wetian sfws.er.usgs.gov/), there are no federally -designated
wetlands located on the Site. A copy of the NWI map which includes wetlands is included in
GeoPlus Physical Settings Maps (GeoSearch 2019b) in Appendix J.
