Kevin,
Thanks again for taking the time to run us by the different areas to discuss issues and highlight potential
concerns. I agree with all that you stated below. I checked the C-Section plan sheets this morning to locate
the last site we visited (pic of plan sheet attached). The concrete inlet was unique. Given the slope and
location of the JS it was a good fit and appears to be functional (pic attached).

As a reminder, at Site 2 on the E Section, your inspectors are required to make notations in NPDES records
regarding EC measure repairs and sediment losses to JSs. If they believe there are losses exceeding a five-
gallon bucket, then those losses need to be reported to me and to DEMLR staff at our Winston Salem office. If
any losses are observed in a JS, they need to make an attempt to retrieve those losses by hand with shovels,
rakes and buckets, doing the least amount of channel damage as possible. They should also walk downstream
a ways to determine the extent of the losses and remove them as well. I know in the Mtns with steep slopes,
sediments are often long gone following a storm event. So common sense applies when determining what is
existing natural sediment vs. those associated with fill from the project. Retrieved sediments should be
brought out to upland areas and incorporated back into existing roadway fills.

We’ll catch up again later this month or next.

Hey Dave - Good seeing you yesterday!
1

Robert and Ryan – Nice to meet both of you and let me know if I can ever be of any assistance!

Also, let me know if any of you have additional questions or concerns regarding the sites we visited yesterday. I’m going
to send an email out to the R-2915E staff and discuss a few items from our visit yesterday. Those will include:
1) making sure the ground cover they put at the bore and jack permit modification site within the wetland at
Permit Site 8 doesn’t contain any non-native seed, and see what the tackifier/green paper contains. This area
will change a lot over the next couple of weeks, but will eventually be seeded with native seed mix, covered
with core fiber, and we will plant silky dogwood and willow live stakes along the creek and within the wetland
area.
2) We will continue to monitor the EC measures at permit site 2 – we obviously lost some sediment to the stream
at this location, but I’m hoping the work they conducted yesterday morning along the ditch line that feeds that
area will help reduce future issues at this site. I plan to visit this area this afternoon, as it has been raining up
there most of the morning, so should be a good time to check.
3) Also at Permit site 2, at the pipe inlet, we will place a large flat Class I or a few Class B stones in the bottom of
the pool at the pipe inlet to help reduce additional scour and a potential head cut. I’ll make sure the rock(s)
does not fill the pool entirely, but just want to cover the bottom to prevent any new scour.

We will also fix the erosion issue around the drop inlet/pipe area at the last site we visited yesterday. It looks like most
of the issue was from water running down the ditchline. Some older wattles were left around the drop inlet that may
be blocking the flow and causing water coming down the ditch line to flow around the box and enter from the other
side. However, the hillside between the concrete apron and the drop inlet is also showing some erosion. Not sure if
that’s from water jumping out of the concrete apron instead of going into the pipe, or an older issue that formed before
we installed the concrete apron and just never was fixed back correctly. Regardless, we will do some work at this site.

Dave – I went by the other sites on your list (attached below) and everything appeared to be in good shape, but more
than happy to visit next time you are up here. I attached a photo of several of those sites above. Lemly Hill and Stat
182 seemed to be doing well, but will be easier to provide photos of, or visit once the vegetation dies back a bit.

Thanks!

Kevin

Hey Kevin,
Some sites I would like to take a look at next week are below:

 E-Section – permit modification area Site 8; Site 15, 2 and anything else that may be active or near
completion on the E-section given that we want to see those areas below too if possible;
 D-Section – Site 6 outlet. We took a look at in 2019 to discuss a rock vane in the outlet or leave as
is. Good discussion points to review and see how it looks now;
 C Section – Moore and Poling Waste Pits restored; Site 13A there was some discussion on baffles in
the culvert as I recall; Site 15 culvert; Lemly Rd area downstream of Permit Site 1,2 where there were
sediment issues in the JS and Koi pond in 2017;
 B Section – Station 182 wetland area and PSH vs. riprap pad; 57-stone clean-up from a previous
inspection;
 A Section - Site 16 outlet repairs we discussed in Nov last year. PSH between sites 19 and 20.

Thanks.
