John,
I was just following up on my previous email. Can you provide us with more information on the sewer project itself?
Thank you.

Thanks. We have a very robust erosion control plan which has been approved by Land Quality. I'll get my GIS folks to
make contact to get the info we need to review the alignment.

HI John,
I accidentally entered in the wrong email for Brian initially, where I cc'd Sue Homewood, Brena Jones (referenced in
email), and Misty Buchanan from the Natural Heritage Program (NHP). I have cc'd them here so you have their contact
information. Usually, that information is available through the NHP and you can contact them (or Misty) specifically
about the natural heritage area.
Thank you for your consideration. If you could include me on emails once you have looked at the impacts, that would be
great.

Oliva: Brian Boyd passed your e-mail on to me. We are the engineers working on the project design for the City of
Greensboro.
I was wonder who I would need to talk to the get a GIS file that shows the boundary of the natural area? If I can get it
into our AutoCAD files, I will be able to determine where we might be impacting the area and see if there are measures
we can take to reduce the impacts.
Thanks, John

Subject: Reedy Fork Creek Sewer Outfall - Riparian Buffer Authorization
Mr. Boyd,
NCWRC has concerns regarding the Reedy Fork Creek Sewer outfall project. The project appears to directly impact the
Brown's Summit Forest/Hardy's Millpond Natural Heritage Natural Area; natural areas are sites with special biodiversity
significance. Immediately downstream, we also have records for the state threatened triangle floater (Alasmidonta
undulata), notched rainbow (Villosa constricta), and the state significantly rare eastern creekshell (V.
delumbis). Although I have not seen if there will be direct impacts to streams or wetlands, we are concerned that the
project may increase sedimentation and erosion of the stream, and the removal of overstory could increase stream
temperatures; therefore, impacting state -listed mussel species. Please see the following preliminary recommendations:
• Our recommendation is to move the sewer line outside the natural heritage natural area, or maintain a
minimum 100-foot undisturbed, native, forested buffer along perennial streams, and a minimum 50-foot buffer
along intermittent streams and wetlands, whichever is greatest.
• We also prefer all crossing of surface waters are either jack and bore or directionally drilled.
• Disturbed stream banks and wetlands should be restored to original contours and re -vegetated with native plant
materials. Lespedeza and fescue should not be used as they are invasive. Native, annual small grains appropriate
for the season are preferred and recommended.
• Minimize corridor maintenance and prohibit mowing between April 1 and October 1 to minimize impacts to
nesting wildlife.
• Pesticides, fertilizers, and other chemicals should not be used in wetland areas or near streams even if they are
labeled as water/wetland friendly.
• Strict sediment and erosion control measures should be used and installed prior to any land -disturbing
activity. Silt fencing, fiber rolls and/or other products should have loose -weave netting that is made of natural
fiber materials with movable joints between the vertical and horizontal twines. Silt fencing that has been
reinforced with plastic or metal mesh should be avoided as it impedes the movement of terrestrial wildlife
species.

Depending upon the impacts to streams, Brena Jones, the aquatic diversity coordinator (cc'd), may have further
recommendations regarding aquatic species.
Thank you,
Olivia

RE: Reedy Fork Creek Sewer Outfall – Riparian Buffers

Dear Ms. Munzer:

Per your comment e-mail of June 30, 2020, we have addressed the comments below. NC Wildlife
Resources Commission comments are in Italic while WithersRavenel’s responses are in Bold.
Additionally, we have attached exhibits that show the limits of the Natural Heritage Area in
relationship to our project.

1. Our recommendation is to move the sewer line outside the natural heritage area, or maintain a
minimum 100-foot undisturbed, naïve, forested buffer along perennial streams, and a minimum
50-foot buffer along intermittent streams and wetlands, whichever is greatest.

The proposed project plans (see attached exhibits) show the sewer line being placed
outside of the regulatory stream buffers wherever possible. The sewer line within the
Natural Heritage Area Boundary is minimal. Due to topographic constraints and specific
gradient for a gravity sewer to function properly. The sewer line has been aligned to
incorporate the natural topography to keep the sewer as shallow as possible. Therefore,
the sewer line can not be moved entirely outside the natural heritage area, as this would
require the sewer line to be significantly deepened in order to overcome the topography
of the site while maintaining the gradient needed for the gravity sewer to function.

2. We also prefer all crossings of surface waters are either jack and bore or directionally drilled.

The two stream crossings and wetland crossing are being installed by jack and bore to
avoid impacts to these features.

3. Disturbed stream banks and wetlands should be restored to original contours and re-vegetated
with native plant materials. Lespedeza and fescue should not be used as they are invasive. Native,
annual small grains appropriate for the season are preferred and recommended.

The stream and wetland crossings will be installed by jack and bore. Any temporary
stream and wetland crossings for construction access will be achieved by temporary
bridges which will span the entire stream and wetlands to avoid disturbance to these
features. Therefore, there is no anticipated impacts disturbance to stream banks or
wetlands. Any disturbed stream banks or wetlands that may be impacted will be
restored to the original contours and seeded with a riparian seed mix to provide
temporary stabilization until natural recruitment permanently revegetates any
disturbed areas.

4. Minimize corridor maintenance and prohibit mowing between April 1 and October 1 to minimize
impacts to nesting wildlife.

Post construction notes will give instructions to minimize impacts to the nesting wildlife
in the corridor.

5. Pesticides, fertilizers, and other chemicals should not be used in wetland areas or near streams
even if they are labeled as water/wetland friendly.

Water/wetland friendly fertilizers will be used during construction as necessary to
promote growth of ground cover to stabilize the easement after construction. Post
construction notes will give instructions to avoid pesticides, fertilizers, and other
chemicals in the wetland areas and near streams.

6. Strict sediment and erosion control measures should be used and installed prior to any land-
disturbing activity. Silt fencing, fiber rolls and/or other products should have loose-weave netting
that is made of natural fiber materials with movable joints between the vertical and horizontal
twines. Silt fencing that has been reinforced with plastic or metal mesh should be avoided as it
impedes the movement of terrestrial wildlife species.

A robust erosion control plan has been developed for the site. The plans indicate that all
devices shall be removed after construction. A copy of the plans is available upon
request.

If you have any additional questions please feel free to contact me at 919-238-0418
