Frank:
To answer your question on the subject property: whether there were any past jurisdictional areas on the property as
far back as in the 1940's — I first looked on the Burke County GIS website (http://gis.burkenc.org/ )
One must keep in mind that the soils maps are Level I surveys with only one soil data point per 500 acres and are only
approximations based on extrapolation of topography, geology and that one soil boring observation point.
The attached map from the Burke County GIS shows the soils, flood zones and blueline streams and the topo was
viewed on the website but would not show up on the pdf. The aerial photography was available from 2009 -2018.
The soils are mapped as Arkqua (AaA) 0-2% slopes, occasionally flooded along Hunting Creek in the darker reddish
brown map unit, and as Fairview sandy clay loam, moderately eroded, (FaB2/FaD2) with 2 — 8% and 15 -25% slopes
respectively, in the lighter brown map unit.
The blue shading shows the flood zone for Hunting Creek. There is a map unit of Fairview coming onto the site from the
northeast, with a crenulation that leads towards the small pond shown to the east.
On the topographic map website, ( https://ngmdb.usgs.gov/topoview/viewer/#15/35.6793/-81.6835 ) there are maps as
far back as 1905 (1941 edition) through 2019.
The maps from 1905 through 1993 are labelled as National Historical Topographic Map Collection (HTMC) and the maps
from 2010 through 2019 are USGS Topographic quadrangle maps.
The accuracy improves as the maps get younger, and the maps were updated as mapping technology improved.
Listed in order from the website:
• 1905 (HTMC 1941 edition) shows the subject site located to the west of the stream (Hunting Creek) —
which is I believe is an inaccuracy due to the age of the map.
• 1956 (HTMC 1956 edition) shows the subject site located to the east of Hunting Creek, and no isolated
pond to the east.

• 1956 (HTMC 1966 edition) shows the subject site located to the east of Hunting Creek, and no isolated
pond to the east.
• 1956 (HTMC 1985 edition) shows the subject site located to the east of Hunting Creek, but with the
small isolated pond to the east, similar to the map on the Burke Co. GIS map.
• 1993 (HTMC 1996 edition) shows the current buildings and the small isolated pond to the east in
purple (as a new edit), at the top of a topographic crenulation at 1200' elevation.
• 2010 (US Topo) shows the small isolated pond to the east, but no topographic contours.
• 2013 (US Topo) shows the small isolated pond to the east, but no topographic contours.
• 2016 (US Topo) does not show the small isolated pond to the east, and with topographic contours
• 2019 (US Topo) shows a blueline to where the small pond was, but no pond and with topographic
contours.
Given this information, I do not believe that there were any jurisdictional wetlands or streams in the
immediate vicinity of the proposed improvements to the Morganton Regional Readiness Center.
Relying on soil and topographic maps, especially older ones, does not accurately depict actual site
conditions. I did note that the topographic crenulation leading to the small pond was at 1200 feet elevation,
and the stream above the larger ponds to the south originated at approximately 1400' elevation, which might
indicate natural springs ocurring between 1200 and 1400 feet elevations to the south and east of the subject
site.
Field verification by a soil scientist could verify the existence of any stream channel modifications that may
have been done, as the soil profile would be disturbed in those areas.
However, any such modifications were done well before any existing regulations and so should not cause
concern from a regualtory perspective.
Let me know if you have any questions.
Best regards,
Robin
