Dear Mr. Wright:
Subject: Federally Endangered and Threatened Species Assessment, Little Snow Creek Habitat
Enhancement and Stream Bank Stabilization Project, Located South of the Intersection
of Moorefield Road and Little Snow Creek Road, in Stokes County, North Carolina
On February 10, 2015, we received a letter from you (via e-mail) in which you requested our
review and comments on the proposed project. We have reviewed the information presented and
we are providing the following comments in accordance with the provisions of the Fish and
Wildlife Coordination Act, as amended (16 U.S.C. 661-667e), and section 7 of the Endangered
Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act).
According to the information provided, the project consists of restoring the dimension, pattern,
and longitudinal profile of a section of Little Snow Creek. The stream channel will be realigned
to create a more stable pattern. The overall stream channel length in the project area will be
reduced from 2,156 linear feet (If) to about 1,7001f. A pump around system will be used to
dewater the area during construction. The stream banks will be reshaped/re-sloped, stabilized
with coir matting and sod mats, and replanted with salvaged woody vegetation. Although rock
cross vanes, log vanes, and J -hooks, toe wood, and root wads are proposed for use in
constructing the new stream channel, your letter did not include specific site plans or designs for
the proposed project.
According to your letter, initial surveys (including an aquatic survey) for federally listed species
were conducted at the site on May 31, 2012. An additional survey for the federally endangered
small-anthered bittercress (Cardamine micrantera) was conducted on August 29, 2014. No
federally listed species were found during the surveys. Suitable habitat for small-anthered
bittercress, although limited, was found within the project area. Based on the information
provided and a review of our database, we believe that no listed species occur within the

proposed project area. Because suitable habitat for small-anthered bittercress occurs within the
project area, we believe the proper determination is "may affect, not likely to adversely affect"
for this species. For all other federally listed species that were included in the county list, we
believe the proper determination is "no effect". Therefore, the requirements under section 7 of
the Act are fulfilled. However, obligations under section 7 of the Act must be reconsidered if:
(1) new information reveals impacts of this identified action that may affect listed species or
critical habitat in a manner not previously considered, (2) this action is subsequently modified in
a manner that was not considered in this review, or (3) a new species is listed or critical habitat is
determined that may be affected by the identified action.
We have no objection to the proposed actions and support any efforts to restore and protect the
water quality in the project area. We appreciate the opportunity to provide these comments. If
we can be of assistance or if you have any questions, please do not hesitate to contact Mr. Bryan
Tompkins of our staff at 828/258-3939, Ext. 240. In any future correspondence concerning this
project, please reference our Log Number 4-2-15-145.

Regarding: Bradley Robertson Stream Stabilization Project
Dear Sirs,
Patricia K. Harris
Director
On June 19th, I accompanied Rodney Wright, Watershed Conservationist with the Stokes County Soil and Water Conservation
District, to evaluate property owned by Bradley Robertson for the presence of jurisdictional wetlands. The wetland
determination was general in nature and associated with a stream stabilization project on little Snow Creek. Little Snow Creek
runs through Mr. Robertson's property and threatens to undercut a farm structure—thus, initiating the stabilization project.
This letter relates preliminary findings prior to a definitive wetland determination performed by the U.S. Army Corp of
Engineers.
The site is located at Mr. Robertson's residence at 2073 Moorefield Road, Danbury, NC 27016 in Stokes County. It is a
pasture in the flood plain of Little Snow Creek. The creek runs west to cast through the middle of the pasture. Hills surround
the site on the north, south, and east sides. The latitude/longitude is 36'27'59"N, 80° 10'23" W.
The primary factor used to make the wetland determination was the presence of hydric soils. A sharpshooter spade and a hand
auger were used to evaluate the soil. Soil munsell color charts were used to describe soil color. Only general observations
were made of hydrologic indicators and wetland plants.
The site is mapped Dan River and Comus soils, 0 to 4 percent, occasionally flooded (DaA). Both soils occupy flood plain
landscape positions. Both are very deep (>60 inches to weathered bedrock) and well drained. On site observations revealed
coarse -loamy to sandy soils with strong brown to yellowish red soil colors. No gray or gleyed redoximorphic matrices or
mottles were observed in the upper 12 to 18 inches of the soil surface, No dark surfaces or organic coated sand grains were
observed, The entire site was traversed and spot checked. No hydric soils were observed at this site.
General observations were made regarding wetland plants and hydrologic indicators. In general, walnut trees (Juglans nigra), a
FacU tree, dominates the tree stratum. Sycamores (Platanus occidentalis) ate next in abundance. A few of birch trees (Betula
spp.) were observed, as well. The latter two tree species are FacW and occur in the immediate vicinity of Little Snow Creek.
The herbaceous layer had isolated plants of common needle rush (Juncus effuses), a FacW plant, occurring near the water line
of the creek. Cane (Arundineria spp.), also FacW, occurs near the water, but is more widespread. Microstegium vimineum, a
Fac+ plant, is especially common in shaded areas adjacent to the creek. No hydric soils are associated in spots where Fac or
wetter plants dominate.

The hydrologic indicators noted at the site are related to flooding events. Aerial photos reveal sandy deposits in areas adjacent
to the stream. A high cut bank undercutting the foundation of a farm structure gives stark evidence of flooding. No other
hydrologic indicators were noted.
Given these findings, I have a high level of confidence that the site contains no jurisdictional wetlands. I anticipate that an in-
depth determination will bear out this conclusion. If there are any comments or questions, please feel free to contact me. My
contact information is below.
