Memo Regarding Russell Gap Post Contract IRT Field Meeting
Memo Date: 1/13/17
This memo will be included in the Mitigation Plan to serve as a record of field discussions including
crediting ratios and approaches.
Meeting Held: 11/28/16 from 12:00 to 5:00
Attendees: Scott King and Jake Byers (Baker); Todd Tugwell, Andrea Hughes, and Kim Browning (Corps
of Engineers); Paul Wiesner and Matthew Reid (DMS), Mac Haupt and Ginny Baker (DWR).
General Notes:
• Scott initially commented that Alexander County is 19.89" below normal rainfall.
• As discussed and agreed upon in the field, areas where buffers are in excess of the required 50'
will be submitted for additional credit using the methodologies described in the October, 2016
Mitigation update and documented in the mitigation plan. The "Revised Credits" shown in the
tables below do not yet account for the potential additional credits. This will be documented in
the mitigation plan.
• Please note that while the October 24, 2016 guidance can be used for implementation of the
project, it is not a requirement of the applicable RFP or DMS contract. This DMS project was
instituted on 10/6/2016.
• Existing wetlands within the current conservation easement may be submitted for wetland
enhancement credit at a 2:1 ratio and documented in the mitigation plan as discussed in the
field.
• All pipe removals will be considered restoration at 1:1 along proposed reaches as measured by
the existing length of pipe as discussed by Todd and Jake.
The originally proposed approaches and ratios for each Reach are provided in the following Tables in
addition to the revised approaches and credits as applicable. Any modifications and discussions are
noted in the text below.

Notes: Length has been revised to reflect the subtraction of the section adjacent to R4
After discussion, the group consensus was that the lower section of R4a could just be lumped into the
rest of R4 at a similar E1 approach at 1.5:1 credit ratio (assuming the same type of work will be done as
for R4), while the upper section of R4a was accepted as proposed as E2 at 2.5:1 ratio. The group
understands that the lower section of R4a being added to R4 will only have a 50' buffer, not the wider
buffer that R4 has proposed.
Todd also found another tributary flowing into R4/R4a from the north (R27) at the fence line along the
property boundary. He was OK with including it as another E2 reach and Baker said they would
investigate further and include in the mitigation plan if applicable. At a minimum, the length of R4b
included inside the conservation easement (50 feet) will be added to the mitigation plan at 2.5:1 ratio.
The group also noticed a wet area between R4a and R26 with the potential for wetland enhancement.
Baker will investigate further and include in the mitigation plan to ensure adequate wetland credits are
provided.

Notes: Length has been revised to reflect the addition of the section adjacent to R4 previously

The group debated the merits of Restoration (either P1 or 132) versus an E1 approach for this reach.
Todd said that 50-60% of the banks seemed OK and was initially reluctant to go with E1. Mac
commented that he felt the reach could be proposed for restoration, and that he was OK with E1
approach as proposed. Jake noted the areas of bank scour and commented that benching will be
included with the proposed E1. Jake also noted the much wider than required buffers for this reach,
especially along the right bank.
The group had a final consensus of accepting E1 at 1.5:1 ratio as proposed.

Todd commented that normally returning a stream back into its original channel from a dug ditch is
normally considered a Restoration approach by definition. He noted that the original channel here has
some water in it and is currently a JD stream. But while expressing concerns, did not reject the
proposed approach outright.
Mac was OK with the approach as proposed.
Group consensus was to be accepting of the Restoration approach at 1:1 credit as proposed.

Notes: The reach has been renamed R7b and accounts for the reduction of R7a from the original reach
of R7 and the inclusion of the 2 culvert removals as restoration at 1:1 as discussed below.
This was a heavily discussed/debated reach. Mac said a mix of R or E1 work seemed appropriate to him.
He wants to see good channel bed and bank work for full credit though. Todd wants to see priority I
floodplain reconnection for R credit and noted you wouldn't get that with E1. Mac noted with this slope
the floodplain wouldn't be too wide here anyway. Mac and Paul then suggested we walk the entire
reach length as well as the two upstream reaches first to consider the stream as a whole before reaching
any further conclusions. So the group walked up to see all of R7, and then R5 and R6.
Later discussion centered on the appropriate approach to be used here. Mac said again he wants to see
more bed form, more pools (few currently exist in stream), good grade control, some structures, good
bank work, etc. But that if that was provided in an E1 approach he was OK with 1.5:1 credit ratio. Todd
and Andrea are inclined to believe that E2 would suffice for much of R7.
So, after further discussion, the group assessed the upper section of R7 (now labeled as R7a) as being
more appropriate for E2 at 2.5:1 ratio. Scott marked the location of this breakpoint with blue flagging
and paced off its location. Upstream of the break (R7a) is E2, while the remaining downstream section
(R7b) is accepted as proposed as E1 at 1.5:1.
Todd stated that the two culvert removals within the lower section of R7 can be counted as restoration
at 1:1. Those 2 culvert lengths total approximately 60 feet and are accounted for in the revised crediting
table above though not broken out as separate reaches for simplicity. Footnotes will be added to
mitigation summary tables in the mitigation plan and monitoring reports to document the increased
credits. He and Jake later discussed using the new mitigation guidance document to increase potential
credits. For example, through increased buffer widths and water quality or benthic sampling efforts.
Todd was agreeable to those being proposed in the mitigation plan.

Notes:
Group thought that raising the channel up and utilizing the two adjacent linear wetland features
(plugging the end of each perhaps?) should raise the surrounding water table and increase flooding
throughout the floodplain area, which has hydric soils and could count for wetland restoration credit if
properly monitored. Baker will investigate this possibility.
Consensus seemed to accept Restoration approach as proposed.
At the small pond at the upper end of one of those linear wetlands, options for a potential BMP were
discussed. The group seemed to agree that leaving the wetlands mostly alone but for plugging the ends
should improve the adjacent wetland function (along with the R9 restoration work). Cattle will be
fenced out of the existing pond/wallow area.

Notes:
Andrea suggested we add wetland enhancement to this section. Todd initially thought E2 would be
more appropriate, while Paul felt that E1 was warranted here. Scott suggested that the functional uplift
potential for both stream and wetlands here justified a higher ratio, noting that the easement protects a
large seep at the top that helps feed to stream.
Mac thought the upper section (above the rock head -cut) was more E2 worthy, while the lower section
that has to be stepped down to the main stem of R1 would require more E1 level work.
In the end, the group consensus was to accept an E2 approach at a 2:1 credit ratio including stabilizing
headcuts.

Notes: The removal of the existing culvert of approximately 20 feet in length will be included at a 1:1
ratio though not broken out as a separate reach.
Starting at the top of the reach, Ginny said she thought it certainly looked perennial (it was flowing up in
this section). Given its incision here, there was some discussion about whether a restoration approach
or a greater ratio could be justified. But as the group walked downstream, the reach became dry and
less incised. Mac commented that if we're raising the bed we need to install gauges to show that proper
flow is present. He also suggested that less work was needed in the middle section, which the group
agreed with. Jake and Todd concurred that there is a concern about losing flow if any channel fill is
conducted. Jake noted the lower culvert would be removed as well. Consensus was to agree to the E1
at 1.5:1 approach as proposed.

on the JD call. This reach will be left in at the current approach unless it is determined to be non -
jurisdictional.

Reach not currently flowing. Mac and Todd felt this was more a linear wetland than stream. A seep
drain that's been dug out — a wet area, not a stream. Andrea noted small drainage area and flat slope.
Mac suggested that with proper gauge monitoring to document flow, it might be demonstrated to be a
stream. Todd is reluctant and would have to see the results of the JD call and the mitigation plan
discussion before accepting as proposed. Reach will be removed from mitigation potential.

Todd reluctant on this reach. It's not currently flowing and he says he's not sure it's jurisdictional. He
noted the small drainage area. Mac recommends gauging the stream to document flow. Scott noted
the huge rainfall deficit in the county and noted that the cattle like to wallow in the seep head and drink
from the small channel. The the functional uplift would be substantial, certainly greater than many E2
projects.
Jake mentioned the photo documentation of flow, sorting, etc in this reach before the drought. Group
consensus ultimately remarked that if the JD doesn't call it jurisdictional, then it shouldn't be included at
all. R24 will remain in as proposed unless it is determined to be non -jurisdictional.

Notes: A 20 foot section of culvert to be removed and counted at 1:1 though not broken out as a

Some discussion here on this reach. Jake noted it keyed out to a strong perennial score, though it is dry
now. Scott again noted that Alexander County is 20" below normal rainfall for the year. Todd initially
inclined to push for Enhancement work here. Mac suggested E1 like for R11 and Ginny agreed. Jake
noted we were going to remove all the headcuts, remove the clogged culvert that's causing bypass flow,
perform benching in spots, banks pulled back, etc. Andrea commented that the channel bed wasn't well
formed in the lower section, but Scott scattered the leaves to reveal a clear sand and gravel bed with
small cobbles present.
After continued debate, the group consensus was for an E1 approach at a 1.5:1 credit ratio.

Comments from IRT members on the above minutes were received on 12/19/16. These comments are
shown below and addressed as needed by Baker.
DWR Comments:
1. R1 -agree
Baker Response: N/A
2. 112 -we really did not discuss this are much, I see this area as a EI/R or R reach
Baker Response: Proposed as El at 1.5:1. If during analysis design and mitigation plan stage, R2 is
determined to warrant more intervention, Baker may propose a restoration level approach.
3. 113 -This whole area at the end of the project, R2 -R3 -R4 is as I stated above more of an EI/R or R
reach, what I am getting at here is I think there is opportunity to do a fair amount of work to the channel
(bed and bank). I am fine with EI. I would rather see the work that needs to be done, which in my view
approaches a Restoration approach.
Baker Response: Proposed as EI at 1.5:1. If during analysis design and mitigation plan stage, R3 is
determined to warrant more intervention, Baker may propose a restoration level approach.
4. R4- their comments reflect my view. I can live with EI.
Baker Response: N/A

8. R7a-b, I think they captured what we discussed here...
Baker Response: N/A
9. R8- Actually what I said to Jake was, "...it looks like someone came and opened up the fence and
put some hay down and now the cows are in ... looks very recent and the stream was essentially
untouched..." Jake said it has been like that for at least 2 years... I can go with Ell but that's essentially a
compromise.
Baker Response: Since Baker has been visiting this site since 2014, cattle have had access to this reach
and use it for shade and feeding. Baker agrees that Ell is the correct approach.
10. R9- their comments captured the discussion

14. R13- I said that I wanted a gauge just below the relict dam feature in the EI section and then lower
down (midway) in the R reach
Baker Response: Baker will propose to install a flow gauge(s) in this reach as part of the mitigation
plan's monitoring requirements.
15. R14- ok with comments here, looks like they included my above comment in this section...
Baker Response: Baker will propose to install a flow gouge(s) in this reach as part of the mitigation
plan's monitoring requirements.
16. R15- their comments are accurate, this reach probably should not be included, will have to keep
watch on this one
Baker Response: As stated in the minutes above, Baker will leave this short reach in the project as a
credit generating reach at an Ell (2.5:1) ratio unless it is determined to be non jurisdictional during
regulatory review. If it is determined to be non jurisdictional, this reach will be removed.

Baker Response: N/A
23. R22- ok with comments
Baker Response: N/A
24. R23- at the end of the discussion, the IRT agreed is was a wetland feature draining to the stream. I
may have mentioned about a gauge but in the end I said this was a wetland feature.
Baker Response: Reach has been removed from mitigation potential.
25. R24-1 thought on this one we recommended this be another wetland drainage feature. I would
suggest that this be removed from stream credit and be wetland.
Baker Response: If this reach is determined to be non jurisdictional by regulatory agencies this reach will
be removed from mitigation potential. If is considered jurisdictional, this reach will remain in the project
at Ell (2.5:1).
26. R25- agreed with the comments
Baker Response: N/A
27. R26- agreed with the comments
Baker Response: N/A
28. R27- ok with comments, should name it Todd Branch...
Baker Response: N/A
We did not really look at the wetland a lot along Davis Creek, probably because it was so dry. I would
urge them to use more than less gauges.
Baker Response: Baker will propose a sufficient amount of monitoring gauges in W1 in the Mitigation
Plan's Monitoring Requirements.
We also talked some about the concern that the proposed re-establishment W1 area might not be
entirely successful which was part of the reason Baker was encouraged to add the wetland
enhancement areas.
Baker Response: Baker will complete additional hydric soils investigations and include the wetland
enhancement areas along R9/R4, R26, and any other areas where hydric soils are present and wetlands
can be enhanced (as determined by Baker and approved by the IRT) in order to provide the contracted
amounts of wetland credits in case areas of wetland along Davis Creek (W1) do not meet the success
criteria. Any additional wetland areas being sought for wetland credit will be included and documented
in the Mitigation Plan.
Corps comments:
Kim Browning:
My notes reflect DWR's for the most part. I noted a few differences:
138 -The only evidence of cattle was at road crossing, and this was recent access. Planting not needed in
this stretch except at crossing. Proposed E 11.
Baker Response: Supplemental planting will be installed outside of the existing wood line to ensure the
entire conservation easement contains native tree and shrub species unless it is determined that the
existing established woody buffer extends outside the conservation easement.
R10 -We agreed on E II (2:1)
Baker Response: N/A
R13 -Andrea noted very little evidence of flow or hydric indicators in the soil in the channel.
Baker Response: Noted. This reach was determined to have a score of 27.75 using NCDWR's stream
classification system. This reach both upstream and downstream of the clogged culvert show strong
indicators of flow, bed and banks, etc.
R23-Wetlead feature. No stream credit.
Baker Response: N/A
R4A-The area above the barn, Ell should be only option here. This isolated section breaks up the project
and being isolated limits what you can do here. There was a discussion about the hayfield near R26 and
R4A, possibly being added as wetland.
Baker Response: Baker is proposing Ell at 2.5:1. The wetland enhancement along R26 and R4a will be
included in the mitigation plan if it is determined that these areas are appropriate for enhancement or
restoration.
R24 -This was a springhead drainage feature that was completely dry with no evidence of flow or hydric
features in the soil. Mac recommended installing a gauge to record flow. It was reported that cattle
wallow in this area. From an agricultural standpoint, this areas should be graded, piped into a watering
tank and install a heavy use area for cattle access to the tank.
Baker Response: This reach is a spring fed reach that flows seasonably. Regarding the use of spring fed
gravity boxes for livestock watering —wells and waterers will be installed on site. Gravity boxes are
notoriously undependable and can dry up. If this reach is determined to be non jurisdictional by
regulatory agencies this reach will be removed from mitigation potential. If is considered jurisdictional,
this reach will remain in the project at Ell (2.5:1).
No other comments were received by the IRT. Please let me know if you have any questions regarding

Hey Todd
I just want to double check to make sure you don't have any additional comments for these memos. I agree with
Andrea; I believe Mac, Ginny, and Kim captured everything.
I would like to get these finalized this week. Let me know and I will have Baker and EW Solutions finalize accordingly.
Thanks

Thanks Paul. I believe Mac, Ginny, and Kim captured everything - Kim took detailed notes. I don't want to speak for
Todd but I'm fine with the comments submitted.

Thanks Andrea. I have forwarded these initial comments to the providers.
Once Todd is back in the office and you have had time to review the memos provided, please let us know if there are any
additional comments.
We will revise the memos and finalize them as necessary.

Hi Paul,
See below for responses to the provider's notes that we have received so far. I have been out of the office so I haven't
had a chance to review the provider's notes yet but I believe DWR and Kim captured any concerns/discrepancies in their
comments. Todd is out of the office until January 3 but may have additional comments when he returns. Please call if
you have questions.
Andrea
Fletcher Site:
DWR Comments:
I have reviewed Steve Melton's site notes and in general agree with the site minutes. It was interesting that I must have
missed two discussions,
first, the Weston Creek low slope discussion, which I am ok with, and secondly, where he stated the IRT indicated that
removal of overburden is typically considered creation, which I am not completely on board with (in some cases yes,
however, if you can show a complete buried profile then I think that would warrant restoration).
Harrell Site:
DWR Comments:
1.They should install gauges for this growing season in both areas they expect to receive wetland credit (rehab, re-
estab.).
2. There was also a brief discussion about the possibility of preserving the stream up to the headwater. They will need a
stream call for the top of the preservation reach.
3. For item numbers 8 and 9 1 have some discrepancies in my notes. I know we talked about adding wells (and a rain
gauge which was not mentioned) to collect baseline data for the coming growing season up to construction time. My
notes say that we requested that data in both the enhancement area and the re-establishment areas. The re-
establishment area would be considered rehabilitation (hydrology and veg improvement) if found to be jurisdictional.
don't have anything in my notes about calling the forested enhancement area re -habilitation, although I may not have
been present for that discussion.
Russell Gap:
DWR Comments:
1. R1 -agree
2. R2 -we really did not discuss this are much, I see this area as a EI/R or R reach
3. 113 -This whole area at the end of the project, R2 -R3 -R4 is as I stated above more of an EI/R or R reach, what I am
getting at here is I think there is opportunity to do a fair amount of work to the channel (bed and bank). I am fine with
EI. I would rather see the work that needs to be done, which in my view approaches a Restoration approach.
4. R4- their comments reflect my view. I can live with E1.
5. R4a- ok with their comments
6. R5- ok, don't think we looked at this too much or had any concerns
7. R6- ok with the comments
8. R7a-b, I think they captured what we discussed here...
9. R8- Actually what I said to Jake was, "...it looks like someone came and opened up the fence and put some hay
down and now the cows are in ... looks very recent and the stream was essentially untouched..." Jake said it has been like
that for at least 2 years... I can go with Ell but that's essentially a compromise.
10. R9- their comments captured the discussion
11. R10- don't remember that we resolved it at 2:1 but I amok with that.
12. R11- ok with their comments
13. R12- ok with comments
14. R13- I said that I wanted a gauge just below the relict dam feature in the EI section and then lower down (midway)
in the R reach
15. R14- ok with comments here, looks like they included my above comment in this section...
4
16. R15- their comments are accurate, this reach probably should not be included, will have to keep watch on this one
17. R16- agree with their comments, removed
18. R17- ok with comments
19. R18- ok with comments
20. R19- ok with comments, need a gauge in this one as well
21. R20- ok with comments, as long as they have flow
22. R21 -don't recall this reach
23. R22- ok with comments
24. R23- at the end of the discussion, the IRT agreed is was a wetland feature draining to the stream. I may have
mentioned about a gauge but in the end I said this was a wetland feature.
25. R24-1 thought on this one we recommended this be another wetland drainage feature. I would suggest that this be
removed from stream credit and be wetland.
26. R25- agreed with the comments
27. R26- agreed with the comments
28. R27- ok with comments, should name it Todd Branch...
We did not really look at the wetland a lot along Davis Creek, probably because it was so dry. I would urge them to use
more than less gauges.
We also talked some about the concern that the proposed re-establishment W1 area might not be entirely successful
which was part of the reason Baker was encouraged to add the wetland enhancement areas
Corps comments:
Kim Browning:
My notes reflect DWR's for the most part. I noted a few differences:
R8 -The only evidence of cattle was at road crossing, and this was recent access. Planting not needed in this stretch
except at crossing. Proposed E 11.
R10 -We agreed on E II (2:1)
R13 -Andrea noted very little evidence of flow or hydric indicators in the soil in the channel.
R23-Wetlead feature. No stream credit.
R4A-The area above the barn, Ell should be only option here. This isolated section breaks up the project and being
isolated limits what you can do here. There was a discussion about the hayfield near R26 and R4A, possibly being added
as wetland.
9
R24 -This was a springhead drainage feature that was completely dry with no evidence of flow or hydric features in the
soil. Mac recommended installing a gauge to record flow. It was reported that cattle wallow in this area. From an
agricultural standpoint, this areas should be graded, piped into a watering tank and install a heavy use area for cattle
access to the tank.
