4. Project Description and History
4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: *
The project site is rural -residential and heavily forested. The project is located west of Sugar Mountain #1 Rd, about 4.8 miles northeast of Newland, NC. The stream site runs through
several residential properties where a small tributary, several wetlands, and multiple ponds are present. Land loss and sedimentation are occurring due to the prevalence of streambank
erosion in poorly vegetated outer bends of the stream.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past? *
Yes No Unknown
4f. List the total estimated acreage of all existing wetlands on the property:
0.128 acres total. 0.12 acres for Wetland 1 (W1) and 0.008 acres for Wetland 2 (W2).
4g. List the total estimated linear feet of all existing streams on the property:
3,367 linear feet.
4h. Explain the purpose of the proposed project: *
The purpose of this project is to stabilize the streambanks of the headwaters of the North Toe River. Approximately 2,007 feet of stabilization is proposed. This will involve the addition of
natural channel structures, such as J-hooks, cross vanes, root -wad and boulder revetments, rock sill/steps, and toe -wood. These structures will reduce erosion along streambanks and
improve the stability of stream reaches.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
This project will provide bank stabilization and grade control using natural channel design structures including J-hooks, cross vanes, root -wad and boulder revetments, rock sill/steps, and
toe -wood. Banks will be sloped back and stabilized using coir matting and live stakes. A riparian buffer of native tree and shrub species will be planted. This proposed construction will
involve the use of track -hoes, skid steers, and dump trucks.
This project will be separated into two reaches, Stream 1 (S1; stations 0+0.0 - 17+3.2) and Stream 2 (S2; stations 0+0.0 - 5+2.6). These reaches are separated by a stream segment that
contains a bedrock gorge and a stream section that was restored during a previous project. Thus, no restoration activities will occur in that reach.
5. Jurisdictional Determinations
5a. Have the wetlands or streams been delineated on the property or proposed impact areas?*
Yes No
Comments:
5b. If the Corps made a jurisdictional determination, what type of determination was made?*

A total of 2,007 linear ft of stream will be impacted for stream restoration on the North Toe River. Approximately 1,602 ft of Reach 1 (S1) and 405 ft of
Reach 2 (S2) are proposed to be permanently impacted.
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:
The proposed project is intended to stabilize approximately 2,007 linear feet of streambank along the headwaters of the North Toe River while
minimizing impacts to aquatic resources. Impacts will be minimized during the installation of natural channel design structures that will improve stream
stability and provide habitat. All disturbed buffer areas will be immediately seeded upon completion, matted (coir matting) and stabilized at the close of
each construction day. A pump around diversion will be installed to bypass water around the active worksite.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
All stream bank disturbances will be stabilized same day, covered with coir matting, and live -staked to reduce sedimentation during construction.
Equipment will work from stream banks whenever possible and only from the channel when it is absolutely necessary. The banks of the restored channel
will be seeded with a native floodplain mix following construction. Live stakes and matting staples will be used to secure the coir matting in these high -
stress areas. The forested riparian buffer will be planted with a variety of native trees following construction.
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?
Yes No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
This is a stream bank restoration project that will not have impacts requiring mitigation for Waters of the U.S. or Waters of the State.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan
la. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?

INSPECTION AND MAINTENANCE:
This consists primarily of two components, stream stabilization
structures (J-Hooks, Cross vanes, etc.) and planting of the stream
banks and riparian areas. In the event that the stream structures
shift, wash away, settle, or otherwise physically cannot function as
designed, contact the area NRCS Agent. If the new plantings
experience a mortality rate of greater than 25%, the dead/dying
plants will need to be replaced.
PERMANENT SEED MIX:
APPLY AT 15 LBS PER ACRE OF DISTURBANCE (per specifications of
seed supplier):
ERNST CONSERVATION SEED MIX ERNMX-178 (FLOODPLAIN MIX)
WHICH INCLUDES THE FOLLOWING SPECIES:
Fox Sedge, Partridge Pea, Dear Tongue, Little Bluestem, Virginia Wild
Rye, Riverbank Wild Rye, Swamp Sunflower, Ox Eye Sunflower, Arrow
Wood, Big Bluestem, Silky Dogwood, Switchgrass, Indiangrass,
Staghorn Sumac, Showy Tick Trefoil, Purple Bergamot, Black Eyed

Seedbed Preparation:
Disturbed soils within riparian areas will be amended to provide an
optimum environment for seed germination and seedling growth.
Surface soils will be loose enough for water infiltration and root
penetration. Lime will be added to the soil to ensure a pH level
between 5.5 - 7. Fertilizer (18-46-0) will be added to nutrient deficient
areas. All riparian areas will be raked to loosen compacted soil prior to
seeding.

approximately 2", and shall not exceed 9". The
material shall drain quickly, and support weight without
shifting or sinking. Larger diameter rocks can be used
at the apex of the arm wedge for scour protection,
installed below the Arm Apex Elevation. Do not place sod
or soil on top of the Header Rocks nor use them to backfill behind
Vane Arm. Any topsoil placed along the Vane Arm shall be for
temporary erosion control seeding and shall be no more then 1-2"
depth. The topsoil shall shall not extend above the elevation of the
Header Rocks.
3. Backfill behind the Vane Arm flush with the Header
Rock elevation until meeting the streambank contour.
4. For finer sediment substrates, outside gravel shall be brought in for
backfill or Geotextile Liner shall be installed (see note 5). Footer Rocks
shall be supported with a layer of stone to prevent sinking or shifting, as
approved by the Project Engineer.
5. Geotextile Liner shall be medium weight non -woven
polypropylene (Weight 7oz/sq yd; Tensile Strength 180
Ibs). Place liner behind the arm (upstream side),
draped from top of rock structure to bottom of footer
rock and extend a minimum of half the trench bottom
width. Trim excess or visible fabric.
6. At the structure apex, extend Footer Rock below scour
depth or to bedrock, whichever is shallower. (The scour
depth is assumed to be the max pool depth
associated with the structure).
7. Step Height is the Total Structure Drop of the water
surface. Maximum water surface (structure) drop
across the Apex Rock is 0.3'-0.5' measured along the
stream thalweg. See Section A and Structure Table.
8. Gaps between Apex Header Rocks will be included due
to larger stream size. The thalweg elevation shall be at
the top of Footer Rocks.
9. Structures will be keyed in at bankfull elevation.
Structures will be keyed in at 2/3 bankfull elevation.
10. After vane arms are installed, stabilize all disturbed
streambank with Riparian Seeding, Streambank Matting,
and Livestakes (see Details).

Notes:
1. Rootwad Revetments are placed along pool facets experiencing
high shear stress along the bank toe where scour protection, flow
deflection, and habitat are desired. Place Rootwad Revetments at
the length and location shown on the Site Plans to provide toe
protection.
2. Rootwads shall consist of a 12"-18" dia. hardwood tree with
15-20' trunk and 4' min. root ball dia. Trunks shall be relatively
straight and free of breaks.
3. Rootwads shall be instated directed upstream into flow with no
more than a 15* departure angle from the bank.
4. Space Rootwads so that root balls overlap 6" min. to create an
integrated revetment.
5. Rootwads shall be angled at min. 2-3% slope downward back into
the bank in order to maintain saturation.
6. Footer Rocks shall be min. 3' intermediate axis dia and placed at
a depth sufficient to prevent scour and to allow for greater than
half of the root ball to extend below the normal flow elevation, in
order to maintain saturation. Scour depth is estimated as the
proposed pool depth, unless otherwise stated.
7. Bracing Rocks shall be 2" dia. and placed near the base of the
root ball with no gaps. Rocks shall be placed between Rootwad
trunks and at either end of Rootwad Revetment to prevent
Rootwads from shifting.
8. Anchor Rocks shall be 2" dia. and placed on top of Rootwad
trunks near the base of the trunk, offset back into the bank to
achieve streambank slope (see Note 11).
9. Footer Rocks and Bracing Rocks shall be backfilled with gravel
alluvial material, if suitable size and consistency is available.
Suitable backfill shall have a min. median diameter of 2" and not
exceed 6" dia. It shall drain quickly and support weight without
shifting or sinking. For fine sediment substrates, outside gravel
may be needed for backfill and Footer Rocks shall be supported
with a layer of stone, as approved by the Project Engineer.
10. Excavate scour pool out in front of Rootwads to the proposed
pool depth (see Longitudinal Profile)
11. After Rootwad Revetment has been instated, backfill streambank
with clean soil fill material and compact at the proposed bank
angle. Backfill shall start at top of Anchor Rock and extend
upwards at X: X slope.

whichever is shallower. The scour depth is estimated to be the
max. pool depth near the structure, unless otherwise specified.
5. Header Rocks must extend upwards above the normal flow
water surface and have an even grade along the length of the
Revetment.
6. Install two or more Header Rocks overlain and offset backwards
moving up the bank if existing substrate elevation is below that
needed for Header Rock to extend up to normal flow elevation
or if additional protection is needed for exposed tree roots or
other bank feature. Do not exceed the inner berm elevation.
7. Footer Rocks and Header Rocks shall be backfilled with gravel
alluvial material, if suitable size and consistency is available.
Suitable backfill shall have a minimum median diameter of 2"
and not exceed 6" dia. It shall drain quickly and support weight
without shifting or sinking. For fine sediment substrates, outside
gravel may be needed for backfill and Footer Rocks shall be
supported with a layer of stone, as approved by the Project
Engineer.
8. After Boulder Revetment has been installed, backfill streambank
with clean soil fill material and compact at the proposed bank

Notes:
1. Constructed Riffle lengths, elevations and slopes
are provided in the Longitudinal Profile.
2. Constructed Riffles shall be composed of natural
alluvial gravel and cobble materials harvested
from the existing channel substrate derived from
excavation activities associated with in —stream
structure installation and scour pool formation.
The particle size shall range from coarse gravel
to medium cobble (32-128mm), as approved by
the Project Engineer. Avoid alluvial materials with
excess fine sediments derived from deposition or
found in the subpavement layers.
3. Add alluvial material on top of the original
substrate up to the proposed thalweg elevation
across the entire channel cross section. Slope
the channel evenly from thalweg to bank toe
(minimum 0.2' elevation difference) to prevent
scour and maintain the thalweg close to the
center of channel.
4. Create heterogeneity in Constructed Riffles by
embedding boulders and woody debris within the
alluvial material as its added to the channel
bottom. For woody debris, use branches and
small logs (<6" dia.) that can be embedded 80%
of the total length. For boulders, embed 50% of
the rock height. Boulders that extend above the
normal flow elevation will have the best habitat
value.

1) The Corps of Engineers believes that there may be jurisdictional aquatic resources in
the review area, and the requestor of this PJD is hereby advised of his or her option
to request and obtain an approved JD (AJD) for that review area based on an
informed decision after having discussed the various types of JDs and their
characteristics and circumstances when they may be appropriate.
2) In any circumstance where a permit applicant obtains an individual permit, or a
Nationwide General Permit (NWP) or other general permit verification requiring "pre -
construction notification" (PCN), or requests verification for a non -reporting NWP or
other general permit, and the permit applicant has not requested an AJD for the
activity, the permit applicant is hereby made aware that: (1) the permit applicant has
elected to seek a permit authorization based on a PJD, which does not make an
official determination of jurisdictional aquatic resources; (2) the applicant has the
option to request an AJD before accepting the terms and conditions of the permit
authorization, and that basing a permit authorization on an AJD could possibly result
in less compensatory mitigation being required or different special conditions; (3) the
applicant has the right to request an individual permit rather than accepting the terms
and conditions of the NWP or other general permit authorization; (4) the applicant can
accept a permit authorization and thereby agree to comply with all the terms and
conditions of that permit, including whatever mitigation requirements the Corps has
determined to be necessary; (5) undertaking any activity in reliance upon the subject
permit authorization without requesting an AJD constitutes the applicant's acceptance
of the use of the PJD; (6) accepting a permit authorization (e.g., signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps permit
authorization based on a PJD constitutes agreement that all aquatic resources in the
review area affected in any way by that activity will be treated as jurisdictional, and
waives any challenge to such jurisdiction in any administrative or judicial compliance
or enforcement action, or in any administrative appeal or in any Federal court; and (7)
whether the applicant elects to use either an AJD or a PJD, the JD will be processed
as soon as practicable. Further, an AJD, a proffered individual permit (and all terms
and conditions contained therein), or individual permit denial can be administratively
appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it
becomes appropriate to make an official determination whether geographic
jurisdiction exists over aquatic resources in the review area, or to provide an official
delineation of jurisdictional aquatic resources in the review area, the Corps will
provide an AJD to accomplish that result, as soon as is practicable. This PJD finds
that there "may be"waters of the U.S. and/or that there "may be" navigable waters of
the U.S. on the subject review area, and identifies all aquatic features in the review
area that could be affected by the proposed activity, based on the following
information:

Project Code: 2022-0057036
Project Name: Sugar Mountain 1
June 23, 2022
Subject: List of threatened and endangered species that may occur in your proposed project
location or may be affected by your proposed project
To Whom It May Concern:
The enclosed species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and designated critical habitat, that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. The enclosed species list
fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the
Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.).
Please note that new species information can change your official species list. Under 50 CFR
402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list
should be verified after 90 days. The Service recommends you visit the ECOS-IPaC website at
regular intervals during project planning and implementation to ensure your species list is
accurate or obtain an updated species list.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the
Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to
utilize their authorities to carry out programs for the conservation of threatened and endangered
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A biological assessment (BA) or biological evaluation (BE) should be completed for your
project. A BA is required for major construction activities (or other undertakings having similar
physical impacts) considered to be Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c))
(NEPA). For projects other than major construction activities, the Service suggests that a BE be
prepared to determine effects of the action and whether those effects may affect listed species
and/or designated critical habitat. E?ects of the action are all consequences to listed species or
critical habitat that are caused by the proposed action, including the consequences of other
06/23/2022 2
activities that are caused by the proposed action. A consequence is caused by the proposed action
if it is reasonably certain to occur and would not occur "but for" the proposed action..
Recommended contents of a BA/BE are described at 50 CFR 402.12. More information and
resources about project review and preparing a BA/BE can be found at the following web link:
https://www.fws. gov/office/asheville-ecological-services/asheville-field-office-online-review-
process-overview.
If a Federal agency determines listed species and/or designated critical habitat may be affected
by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR
402. The Service is not required to concur with "no effect" determinations from Federal action
agencies. If consultation is required, the Service recommends that candidate species, proposed
species, proposed critical habitat, and at -risk species be addressed within the consultation. More
information on the regulations and procedures for section 7 consultation, including the role of
permit or licensed applicants, can be found in the "Endangered Species Consultation Handbook"
at the following web link: https://www.fws.gov/media/endangered-species-consultation-
handbook.
Migratory Birds: In addition to responsibilities to protect threatened and endangered species
under the Act, there are additional responsibilities under the Migratory Bird Treaty Act (MBTA)
and the Bald and Golden Eagle Protection Act (BGEPA) to protect native birds from project -
related impacts. Any activity, intentional or unintentional, resulting in take of migratory birds,
including eagles, is prohibited unless otherwise permitted by the Service (50 C.F.R. Sec. 10.12
and 16 U.S.C. Sec. 668(a)). More information about MBTA and BGEPA can be found at the
following web link: hops://www.fws.gov/program/migratory-birds.
We appreciate your consideration of Federally listed species. The Service encourages Federal
agencies to include conservation of threatened and endangered species in their project planning
to further the purposes of the Act. Please contact our staff at 828-258-3939, if you have any
questions. In any future correspondence concerning this project, please reference the
Consultation Code which can be found in the header of this letter.

The birds listed below are birds of particular concern either because they occur on the
USFWS Birds of Conservation Concern (BCC) list or warrant special attention in your
project location. To learn more about the levels of concern for birds on your list and how this
list is generated, see the FAQ below. This is not a list of every bird you may find in this location,
nor a guarantee that every bird on this list will be found in your project area. To see exact
locations of where birders and the general public have sighted birds in and around your project
area, visit the E-bird data mapping tool (Tip: enter your location, desired date range and a species
on your list). For projects that occur off the Atlantic Coast, additional maps and models detailing
the relative occurrence and abundance of bird species on your list are available. Links to
additional information about Atlantic Coast birds, and other important information about your
migratory bird list, including how to properly interpret and use your migratory bird report, can be

Probability Of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be
present in your project area. This information can be used to tailor and schedule your project
activities to avoid or minimize impacts to birds. Please make sure you read and understand the
FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting
to interpret this report.
Probability of Presence (■)
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your
project overlaps during a particular week of the year. (A year is represented as 12 4-week
months.) A taller bar indicates a higher probability of species presence. The survey effort (see
below) can be used to establish a level of confidence in the presence score. One can have higher
confidence in the presence score if the corresponding survey effort is also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in
the week where the species was detected divided by the total number of survey events for
that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee
was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is
0.25.
06/23/2022 3
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum
probability of presence across all weeks. For example, imagine the probability of presence
in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12
(0.25) is the maximum of any week of the year. The relative probability of presence on
week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the
probability of presence score.
Breeding Season ( )
Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds across
its entire range. If there are no yellow bars shown for a bird, it does not breed in your project
area.
Survey Effort (I)
Vertical black lines superimposed on probability of presence bars indicate the number of surveys
performed for that species in the 10km grid cell(s) your project area overlaps. The number of
surveys is expressed as a range, for example, 33 to 64 surveys.
No Data (—)
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are based on
all years of available data, since data in these areas is currently much more sparse.

Migratory Birds FAQ
Tell me more about conservation measures I can implement to avoid or minimize impacts
to migratory birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize
impacts to all birds at any location year round. Implementation of these measures is particularly
important when birds are most likely to occur in the project area. When birds may be breeding in
the area, identifying the locations of any active nests and avoiding their destruction is a very
helpful impact minimization measure. To see when birds are most likely to occur and be breeding
in your project area, view the Probability of Presence Summary. Additional measures or permits
may be advisable depending on the type of activity you are conducting and the type of
infrastructure or bird species present on your project site.
What does IPaC use to generate the migratory birds potentially occurring in my specified
location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern
(BCC) and other species that may warrant special attention in your project location.
The migratory bird list generated for your project is derived from data provided by the Avian
Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding,
and citizen science datasets and is queried and filtered to return a list of those birds reported as
occurring in the 10km grid cell(s) which your project intersects, and that have been identified as
warranting special attention because they are a BCC species in that area, an eagle (Eagle Act
requirements may apply), or a species that has a particular vulnerability to offshore activities or
development.
06/23/2022 5
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your
project area. It is not representative of all birds that may occur in your project area. To get a list
of all birds potentially present in your project area, please visit the AKN Phenology Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds
potentially occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data
provided by the Avian Knowledge Network (AKN). This data is derived from a growing
collection of survey, banding, and citizen science datasets .
Probability of presence data is continuously being updated as new and better information
becomes available. To learn more about how the probability of presence graphs are produced and
how to interpret them, go the Probability of Presence Summary and then click on the "Tell me
about these graphs" link.
How do I know if a bird is breeding, wintering, migrating or present year-round in my
project area?
To see what part of a particular bird's range your project area falls within (i.e. breeding,
wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab
of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of
interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your
migratory bird species list has a breeding season associated with it, if that bird does occur in your
project area, there may be nests present at some point within the timeframe specified. If "Breeds
elsewhere" is indicated, then the bird likely does not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern
throughout their range anywhere within the USA (including Hawaii, the Pacific Islands,
Puerto Rico, and the Virgin Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation
Regions (BCRs) in the continental USA; and
3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on
your list either because of the Eagle Act requirements (for eagles) or (for non -eagles)
potential susceptibilities in offshore areas from certain types of development or activities
(e.g. offshore energy development or longline fishing).
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made,
in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC
species of rangewide concern. For more information on conservation measures you can
implement to help avoid and minimize migratory bird impacts and requirements for eagles,
please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species
and groups of bird species within your project area off the Atlantic Coast, please visit the
Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides
06/23/2022 6
birds that may be helpful to you in your project review. Alternately, you may download the bird
model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical
Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic
Outer Continental Shelf project webpage.
Bird tracking data can also provide additional details about occurrence and habitat use
throughout the year, including migration. Models relying on survey data may not include this
information. For additional information on marine bird tracking data, see the Diving Bird Study
and the nanotag studies or contact Caleb Spiegel or Pam Loring.
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid
violating the Eagle Act should such impacts occur.
Proper Interpretation and Use of Your Migratory Bird Report
The migratory bird list generated is not a list of all birds in your project area, only a subset of
birds of priority concern. To learn more about how your list is generated, and see options for
identifying what other birds may be in your project area, please see the FAQ "What does IPaC
use to generate the migratory birds potentially occurring in my specified location". Please be
aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that
overlap your project; not your exact project footprint. On the graphs provided, please also look
carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no
data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey
effort is high, then the probability of presence score can be viewed as more dependable. In
contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of
certainty about presence of the species. This list is not perfect; it is simply a starting point for
identifying what birds of concern have the potential to be in your project area, when they might
be there, and if they might be breeding (which means nests might be present). The list helps you
know what to look for to confirm presence, and helps guide you in knowing when to implement
conservation measures to avoid or minimize potential impacts from your project activities,
should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell
me about conservation measures I can implement to avoid or minimize impacts to migratory
birds" at the bottom of your migratory bird trust resources page.
