4h. Explain the purpose of the proposed project:*
Upstream development and placement of existing natural channel design structure materials, as well as flooding conditions have caused bank instability and erosion onsite. The
purpose of the project was to stabilize erosive banks by repairing natural channel design structures (exclusively located on the right bank) within a 70 linear foot reach of the Watauga
River. Any localized temporary impacts that arose during construction were addressed by end of day. Existing materials were used to address the existing degradation at the time of
construction.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
Repair of bank stabilization structures from existing materials was executed in October, 2019 within a 70 linear feet of the Watauga River. During structure repair, banks were sloped to
a 3:1 ratio, or less, via hand grading and existing boulders/biotextile matting were used to construct appropriate armoring of the right bank of the Watauga River. Ernst Conservation
Seed Mix was sovm (at a 75-150 Ibs/acre) under live staked Excelsior erosion control matting within eroded areas of the 70 linear foot reach. Minimal construction equipment was used
for resloping impacted areas of the relic channel bank.

3j. Comments:
Approximately 30 linear feet of a relic channel (0.001 acres) is a violation restoration that occurred during structure repair. Repair of these impacts to
the Watauga River has been implemented post construction within 15 days post incident.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
During structure repair of 70 linear feet of Watauga River, existing structure materials were repurposed to avoid impacts associated with bringing in
additional materials for construction. Localized temporary impacts due to construction access of the Watauga River were matted (staked Excelsior)
and seeded (Ernst Conservation Seed Mix) post bank sloping at a 3:1 ratio, or less, for adequate bank stabilization and reduction of sedimentation.
Construction access areas were minimized vdthin riparian buffer to reduce amount of possible impacts.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Low intensity construction equipment was restricted to one stream bank access route along the Watauga River in an effort to reduce area and
intensity of impact. Only well maintained equipment was used; no leaks were tolerated. Construction staff operated equipment from streambanks
whenever possible. No additional construction materials were brought onsite for the structure repair eliminating a staging area for material storage.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
r Yes f• No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Proper erosion control techniques were implemented to stabilize impacted banks within 15 days post -incident to abate in -stream impacts to water quality and wildlife habitat.
F. Stormwater Management and Diffuse Flow Plan (required by DWR) u
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
r Yes r No
If no, explain why:
The project is not within an NC Riparian Buffer Protection Area.
2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?*
r Yes r No
2b. Does this project meet the requirements for low density projects as defined in 15ANCAC 02H .1003(2)?

Riparian Buffer Rules (15A NCAC 2B .0200)? *
r Yes r No
2b Provide an explanation of the violation(s):
Impacts to the banks of a relic channel of the Watauga River were made during the structure repair of the 70 linear foot reach of the Watauga River
(exclusively right bank). Impacts to the relic channel are labeled on the Twin Rivers Structure Repair Site Plan Map (attached in section C4j.) as
"Violation Restoration". Proper erosion control techniques were implemented to stabilize impacted banks within 15 days post -incident to abate in -
stream impacts to water quality and Wildlife habitat.
3. Cumulative Impacts (DWR Requirement)
3a. Will this project result in additional development, which could impact nearby downstream water quality?*
r Yes r No
3b. If you answered "no," provide a short narrative description.

November 22, 2019
Subject: Consistency letter for the 'Twin Rivers' project indicating that any take of the northern
long-eared bat that may occur as a result of the Action is not prohibited under the ESA
Section 4(d) rule adopted for this species at 50 CFR §17.40(o).
Dear Sarah Duke:
The U.S. Fish and Wildlife Service (Service) received on November 22, 2019 your effects
determination for the 'Twin Rivers' (the Action) using the northern long-eared bat (Myotis
septentrionalis) key within the Information for Planning and Consultation (IPaC) system. You
indicated that no Federal agencies are involved in funding or authorizing this Action. This IPaC
key assists users in determining whether a non -Federal action may cause "take"fil of the northern
long-eared bat that is prohibited under the Endangered Species Act of 1973 (ESA) (87 Stat.884,
as amended; 16 U.S.C. 1531 et seq.).
Based upon your IPaC submission, any take of the northern long-eared bat that may occur as a
result of the Action is not prohibited under the ESA Section 4(d) rule adopted for this species at
50 CFR §17.40(o). Unless the Service advises you within 30 days of the date of this letter that
your IPaC-assisted determination was incorrect, this letter verifies that the Action is not likely to
result in unauthorized take of the northern long-eared bat.
Please report to our office any changes to the information about the Action that you entered into
IPaC, the results of any bat surveys conducted in the Action area, and any dead, injured, or sick
northern long-eared bats that are found during Action implementation.
If your Action proceeds as described and no additional information about the Action's effects on
species protected under the ESA becomes available, no further coordination with the Service is
required with respect to the northern long-eared bat.
The IPaC-assisted determination for the northern long-eared bat does not apply to the following
ESA -protected species that also may occur in your Action area:
• Blue Ridge Goldenrod, Solidago spithamaea (Threatened)
• Bog Turtle, Clemmys muhlenbergii (Similarity of Appearance (Threatened))
• Carolina Northern Flying Squirrel, Glaucomys sabrinus coloratus (Endangered)

11/22/2019 IPaC Record Locator: 973-19202699
• Gray Bat, Myotis grisescens (Endangered)
• Heller's Blazingstar, Liatris helleri (Threatened)
• Roan Mountain Bluet, Hedyotis purpurea var. montana (Endangered)
• Spreading Avens, Geum radiatum (Endangered)
• Spruce -fir Moss Spider, Microhexura montivaga (Endangered)
• Virginia Big -eared Bat, Corynorhinus (=Plecotus) townsendii virginianus (Endangered)
You may coordinate with our Office to determine whether the Action may cause prohibited take
of the animal species listed above.
[1]Take means to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to
attempt to engage in any such conduct [ESA Section 3(19)].

Action Description
You provided to IPaC the following name and description for the subject Action.
1. Name
Twin Rivers
2. Description
The following description was provided for the project 'Twin Rivers':
The project site is along the Watauga River in the Twin Rivers Community,
Foscoe, NC (36.16533611°,-81.75666667°). The site consists within two parcels
in the Twin Rivers Community and approximately 137 linear feet of stabilization.
The purpose of the project is to stabilize eroding banks of the Watauga River in
the Twin Rivers subdivision.
Approximate location of the project can be viewed in Google Maps: https://www.google.com/

Sti
Determination Key Result
This non -Federal Action may affect the northern long-eared bat; however, any take of this
species that may occur incidental to this Action is not prohibited under the final 4(d) rule at 50
CFR §17.40(o).
Determination Key Description: Northern Long-eared Bat 4(d) Rule
This key was last updated in IPaC on May 15, 2017. Keys are subject to periodic revision.
This key is intended for actions that may affect the threatened northern long-eared bat.

11/22/2019 IPaC Record Locator: 973-19202699 4
The purpose of the key for non -Federal actions is to assist determinations as to whether proposed
actions are excepted from take prohibitions under the northern long-eared bat 4(d) rule.
If a non -Federal action may cause prohibited take of northern long-eared bats or other ESA -listed
animal species, we recommend that you coordinate with the Service.

11/22/2019 IPaC Record Locator: 973-19202699 5
Determination Key Result
Based upon your IPaC submission, any take of the northern long-eared bat that may occur as a
result of the Action is not prohibited under the ESA Section 4(d) rule adopted for this species at
50 CFR § 17.40(o).
Qualification Interview
1. Is the action authorized, funded, or being carried out by a Federal agency?
No
2. Will your activity purposefully Take northern long-eared bats?
No
3. Is the project action area located wholly outside the White -nose Syndrome Zone?
Automatically answered
No
4. Have you contacted the appropriate agency to determine if your project is near a known
hibernaculum or maternity roost tree?
Location information for northern long-eared bat hibernacula is generally kept in state
Natural Heritage Inventory databases — the availability of this data varies state -by -state.
Many states provide online access to their data, either directly by providing maps or by
providing the opportunity to make a data request. In some cases, to protect those resources,
access to the information may be limited. A web page with links to state Natural Heritage
Inventory databases is available at www.fws.gov/midwest/endangered/mammals/nleb/
nhisites.html.
Yes
Will the action affect a cave or mine where northern long-eared bats are known to
hibernate (i.e., hibernaculum) or could it alter the entrance or the environment (physical or
other alteration) of a hibernaculum?
No
6. Will the action involve Tree Removal?
No
