4. Project Description and History
4a. Describe the existing conditions on the site and the general land use in the vicinityof the project at the time of this application:*
The epsting McDonald Road culvert is a 36" reinforced concrete pipe (RCP) with a loosely formed concrete embankment at the upstream end and an eroding rock wall embankment /
headwall at the downstream end. The downstream end of the culvert is perched at least 18" above the epsting bed of the stream. The epsting culvert outfall is appropmately 10' from
the edge of the road pavement, and the embankment is actively eroding, threatening the integrity of the road. Hydraulic analysis indicates the existing culvert is not adequately sized for
10- year storm events or larger. NC SAM assessment classified the stream as "High Quality".
The general land use in the vicinity and throughout the watershed is single family residential with some industrial and commercial use as well as wooded areas. McDonald road serves
as a one-way in/ out for multiple housing developments.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past?*
r Yes r No r Unknown
4d. Attach an 8 1/2 X 11 excerpt from the most recent version of the USGS topographic map indicating the location of the project site. (for DWR)

4f. List the total estimated acreage of all existing wetlands on the property:
4g. List the total estimated linear feet of all existing streams on the property:
194
4h. Explain the purpose of the proposed project:*
The purpose of the project is to replace the epsting eroding 45-LF RCP which is threatening the integrity of the road and is undersized and perched at the downstream end. The
replacement culvert will be a 54-LF 9'X7' box culvert designed to pass the 25 yr storm and prevent the 100 yr storm from overtopping the road as the road is the single access point for
a residential area.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The project will consist of replacing the existing 45-LF 36" RCP with a 54-LF 9'X7' box culvert and associated headwalls. In order to tie the downstream headwall into wasting grades and
stabilize the downstream channel banks, some additional bank grading will occur downstream. These regraded banks will be further stabilized with rock toe protection using existing
native bed material. As McDonald Road is the single access for residential areas, a 38-LF temporary road crossing utilizing two 48" steel encasement pipes will be installed upstream of
the current crossing during construction. It is anticipated that this crossing will be in use for 1-3 months during culvert construction.
The replacement concrete box culvert was designed with vertical bends to limit the amount of bedrock excavation required for installation (and thus reduce the duration of repair) while
alloWng the culvert to be properly buried at both ends and meet the epsting channel grade. In order to facilitate aquatic life movement and limit the amount of substrate transport
through the pipe, 8" high X 8" wide concrete sills (12" high X 8" wide at the vertical bends) will be installed across the width of the culvert every 5' longitudinally along the length of the
culvert. These sills will have a central 3.5' notch in the center to allowfor baseflow passage and will be backfilled with stone and native site soils. Though the -15 % grade within the
central portion of the culvert is not in strict compliance with USACE/NCDWR aquatic life passage guidance, CSWS has worked to mapmize acceptable life passage conditions within the
culvert while minimizing the overall length of stream to be impacted by culvert installation.
Banks that have been regraded or disturbed by the temporary crossing will be matted and planted with native live stakes / containerize plantings. Construction will be performed by
standard commercial construction equipment. No specialized equipment not regularly seen on construction projects is anticipated.

E. Impact Justification and Mitigation u
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Multiple culvert options were initially designed that involved impacts to a larger length of channel; the proposed option was chosen as it minimized the
linear feet of channel impacted while maArnizing the potential for aquatic life passage. Designs were modified to utilize native bed material for
stabilization, rather than relying on the addition of riprap to the channel bed.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
During construction, appropriate sediment and erosion control practices equaling those outlined in the most recent version of the "North Carolina
Sediment and Erosion Control Planning and Design Manual' vdll be used to minimize impacts to the stream. Temporary coffer dams and a pump
around will be used during concrete installation so that work will occur "in -the -dry".
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 r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
The project does not require mitigation due to the minimal nature of the impacts (only 9 LF permanent loss of stream bed). The majority of impacts will not result in loss of waters.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)

1. Diffuse Flow Plan

Miscellaneous
Comments
CSWS is requesting a waiver from the buried culvert/ aquatic life passage regional conditions as the project does not strictly follow the aquatic life passage recommendations due to a
portion of replacement culvert exceeds recommended slopes.
Typically these activities would be authorized under RGP 163 (Charlotte Storm Water Services); in this instance, authorization under NWP 3 is being requested as the upstream and
downstream channels were classified as High Quality by NC SAM and RGP 163 is not be used on channels classified as High Quality.

Project Name: McDonald Road SDIP
August 11, 2020
Subject: List of threatened and endangered species that may occur in your proposed project
location, and/or may be affected by your proposed project
To Whom It May Concern:
The attached species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and final designated critical habitat, that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. Although not required by
section 7, many agencies request species lists to start the informal consultation process and begin
their fulfillment of the requirements under section 7(c) of the Endangered Species Act (Act) of
1973, as amended (16 U.S.C. 1531 et seq.).
This list, along with other helpful resources, is also available on the U.S. Fish and Wildlife
Service (Service) Asheville Field Office's (AFO) website: https://www.fws.gov/raleigh/species/
cntylist/nc counties.html. The AFO website list includes "species of concern" species that could
potentially be placed on the federal list of threatened and endangered species in the future. Also
available are:

08/11/2020 Event Code: 04EN1000-2020-E-01940
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could require modifications of these lists.
Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act,
the accuracy of the species lists should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website or the AFO website (the AFO website dates each
county list with the day of the most recent update/change) at regular intervals during project
planning and implementation for updates to species lists and information. An updated list may be
requested through the ECOS-IPaC system by completing the same process used to receive the
enclosed list or by going to the AFO website.
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 is required for construction projects (or other undertakings having
similar physical impacts) that are major 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)). For projects other than major construction activities, the Service suggests that a Biological
Evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12 and on our office's website
at https://www.fws.gov/asheville/htmis/project review/assessment guidance.html.
If a Federal agency (or their non-federal representative) determines, based on the Biological
Assessment or Biological Evaluation, that 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. In addition, the Service recommends that candidate species, proposed species, and
proposed critical habitat be addressed within the consultation. More information on the
regulations and procedures for section 7 consultation, including the role of permit or license
applicants, can be found in the "Endangered Species Consultation Handbook" at: http://
www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF.
Though the bald eagle is no longer protected under the Endangered Species Act, please be aware
that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16
U.S.C. 668 et seq.), and projects affecting these species may require additional consultation (see
https://www.fws.gov/southeast/our-services/permits/eagles/). Wind energy projects should follow
the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to
migratory birds (including bald and golden eagles) and bats.
Guidance for minimizing impacts to migratory birds for projects including communications
towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http://
www. fws. gov/migratorybirds/CurrentBirdlssues/Hazards/towers/towers.htm;

We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Tracking Number in
the header of this letter with any request for consultation or correspondence about your project
that you submit to our office.

Endangered Species Act Species
There is a total of 5 threatened, endangered, or candidate species on this species list.
Species on this list should be considered in an effects analysis for your project and could include
species that exist in another geographic area. For example, certain fish may appear on the species
list because a project could affect downstream species.
IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA
Fisheriesi, as USFWS does not have the authority to speak on behalf of NOAA and the
Department of Commerce.
See the "Critical habitats" section below for those critical habitats that lie wholly or partially
within your project area under this office's jurisdiction. Please contact the designated FWS office
if you have questions.

Migratory Birds
Certain birds are protected under the Migratory Bird Treaty Act! and the Bald and Golden Eagle
Protection Actz.
Any person or organization who plans or conducts activities that may result in impacts to
migratory birds, eagles, and their habitats should follow appropriate regulations and consider
implementing appropriate conservation measures, as described below.
1. The Migratory Birds Treaty Act of 1918.
2. The Bald and Golden Eagle Protection Act of 1940.
3. 50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)
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 found
below.
For guidance on when to schedule activities or implement avoidance and minimization measures
to reduce impacts to migratory birds on your list, click on the PROBABILITY OF PRESENCE
SUMMARY at the top of your list to see when these birds are most likely to be present and
breeding in your project area.
BREEDING SEASON
Wood Thrush Hylocichla mustelina Breeds May 10 to Aug 31
This is a Bird of Conservation Concern (BCC) throughout its range in the
continental USA and Alaska.
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

08/11/2020 Event Code: 04EN1000-2020-E-01940
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:
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.
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 (1)
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 and/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
(BCQ 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.

08/11/2020 Event Code: 04EN1000-2020-E-01940 4
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

08/11/2020 Event Code: 04EN1000-2020-E-01940 5
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
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 Lorin.
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.

Dear Ashley Bentz.
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
Based on the project area mapped with your request, a query of the NCNHP database indicates that
there are no records for rare species, important natural communities, natural areas, and/or
conservation/managed areas within the proposed project boundary. Please note that although there
may be no documentation of natural heritage elements within the project boundary, it does not
imply or confirm their absence, the area may not have been surveyed. The results of this query
should not be substituted for field surveys where suitable habitat exists. In the event that rare
species are found within the project area, please contact the NCNHP so that we may update our
records.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is found within the project area or is indicated within a one -mile radius of
the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for
guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a
Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund
easement, or Federally -listed species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rodnev.butlerWncdcr.aov or 919-707-8603.
Sincerely,
