SUBJECT: 20 South Bear Creek
UT to Hominy Creek, Buncombe County
Dear Ms. Fuemmeler:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed an
application to culvert 60 ft of an unnamed tributary (UT) to Hominy Creek, fill 0.018 acre of
wetland, and temporarily impact 30 ft of stream and 0.004 acre of wetland in Buncombe County.
Our comments on this application are offered for your consideration under provisions of the
Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish and Wildlife Coordination Act (48
Stat. 401, as amended; 16 U.S.C. 661-667d).
Wild trout reproduction should not be impacted by the project, and a trout moratorium is not
needed. However, Blotched Chub (Erimystax insignis, NC Significantly Rare) is found
downstream of the project, and effective erosion and sediment control on site is important to
conserve habitat for this species.
The project application proposes to culvert the stream with two 72-inch culverts. Double
culverts set at the same elevation often result in one culvert carrying most or all of the flows over
time; this can cause channel instability and problems with aquatic organism passage. We
recommend replacing the double culverts with a spanning structure such as a bridge or
bottomless arch instead. If a culvert must be used, we recommend using a single larger squash
(or elliptical) pipe capable of carrying base and stormflows, possibly with a floodplain culvert
placed at a higher elevation to pass flood flows. In addition, culvert material is not specified.
We recommend against slick -walled high -density polyethylene (HDPE) and reinforced concrete,
as these materials are smooth and are less likely to retain substrate and allow passage of aquatic
organisms like salamanders and crayfish.

It also appears that part of the development will be in the 100-year floodplain. The NCWRC
does not support commercial or residential development within the 100-year floodplain. The
filling of floodplains increases the potential for flooding and degrades in -stream habitats for fish
and other aquatic organisms.
We offer the following recommendations to minimize impacts to fish and wildlife:
1. In -channel work should be accomplished as quickly as possible and vigilance used in
sediment and erosion control during site preparation, construction, and clean up. Disturbed
areas should be seeded, mulched and/or matted as soon as possible, preferably at the end of
each workday.
2. Any erosion control matting used should be free of plastic or nylon mesh, as this type of
mesh frequently entangles wildlife and is slow to degrade, resulting in a hazard that may last
for years.
3. We recommend that the stream running through the property be planted with a riparian buffer
at least 30 ft in width comprised of native trees, shrubs, and herbaceous vegetation. In
addition, we recommend widening the buffer on Hominy Creek to at as wide as possible and
using this area as green space. A wide forested buffer can ensure greater bank stability, filter
overland pollutants, and provide habitat for birds and other wildlife.
4. We strongly recommend using a spanning structure such as a bridge or arch pipe; if a culvert
must be used, we recommend a single corrugated squash/elliptical pipe, possibly with an
additional floodplain culvert set at a higher elevation. In addition, smooth -walled culvert
material should not be used.
5. If temporary wetland impacts involve heavy equipment access, then equipment should work
from mud mats to lessen wetland soil compaction.
6. Effective stormwater management is essential in minimizing impacts to downstream waters.
Stormwater control measures should mimic the hydrograph consistent with an impervious
coverage of less than 10%. We recommend the use of Low Impact Design techniques, such
as grassed swales and pervious pavement; curb and gutter, catch basins, and underground
piping of stormwater should be avoided. As stormwater runoff from pavement can cause
short-term temperature spikes in downstream waters, mechanisms to lower stormwater
temperature should be incorporated into the stormwater management design.
Thank you for the opportunity to review and comment on this project. Please contact me at
