Charlotte -Mecklenburg Stormwater Services I Hinsdale-Tinkerbell SDIP
Pre -Construction Notification
Project History
On June 10, 2020, a Pre -Construction Notification (PCN) was submitted to the United
States Army Corps of Engineers (USACE) and the NC Department of Environmental
Quality (NCDEQ) Division of Water Resources (DWR) to request authorization for activities
associated with storm drainage infrastructure construction and channel improvements
under CMSWS' Regional General Permit (RGP) 163 and Water Quality General
Certification (WQGC) 4147. Activities associated with sanitary sewer infrastructure updates
were requested to be authorized under Nationwide Permit (NWP) 3 and WQGC 4133.
On August 21, 2020, the USACE issued approval for RGP 163 and NWP 3 (Appendix B,
SAW-2018-02116). On August 18, 2020, the NCDEQ-DWR issued approval for WQCG
4147 and 4133 (Appendix B, DWR #20-0788). The NWP 3 and WQGC 4133 approvals
expired on March 18, 2022 and the RGP 163 and WQGC 4147 approvals expired April 24,
2022. Construction of the Project began on May 11, 2021, is currently ongoing and is
allowable to occur within the grace period of one year post permit expiration; however,
construction of the Project will not be completed by March 2023.
In the USACE approval issued, a Preliminary Jurisdiction Determination Verification was
also provided (Appendix B, SAW-2018-02116).
Current Request
As the project is currently in construction and will not be completed by the expiration date
of the authorized permits, HDR Engineering, Inc. of the Carolinas (HDR), on behalf of our
client Charlotte -Mecklenburg Storm Water Services (CMSWS) is requesting
reauthorization of previously permitted impacts under RGP 163 and WQGC 4508 (replaces
WQGC 4147) for activities associated with storm drainage infrastructure construction and
under NWP 3 and WQGC 4239 (replaces WQGC 4133) for activities associated with
sanitary sewer infrastructure updates that will not be completed by March 2023. The PCN
(Appendix C) also seeks to authorize new temporary and permanent non -loss impacts
associated with the Project that were not previously authorized. A Pre -Filing Meeting
Request Pursuant to 40 CFR § 121.4 was submitted to NCDEQ-DWR on December 1,
2022 (Appendix C), in advance of this PCN request. Construction is anticipated to be
complete in January 2024.
Impacts
Table 1 summarizes total Project impacts by those previously authorized and completed,
those previously authorized that require reauthorization, and newly added impacts (either
brand new impacts or after -the -fact impacts). Table 2 summarizes impacts that are
submitted in this PCN.

Of the 84 linear feet of new impacts, 26 linear feet of temporary impacts, 28 linear feet of
permanent non -loss impacts, and 12 linear feet of permanent loss impacts have already
either been completed or are currently in construction, and 18 linear feet of temporary
impacts have yet to occur. An email documenting after -the -fact documentation is provided
in Appendix D. Please note, new Impact 18B, was inadvertently missed when requesting
after -the -fact authorization for 12 LF of permanent non -loss impacts to an intermittent
stream (Stream 5).

Cultural Resources
The National Park Service National Register of Historic Places (NRHP) GIS Public Dataset
and the NC Historic Preservation Office (NCHPO) HPOWEB GIS Web Service' were
reviewed. These sources revealed there are no known cultural resources, historic
structures, or historic districts located within the Study Area. Archaeological data were not
included as part of the NCHPO GIS services and were not assessed as part of this review.
Protected Species
HDR obtained and reviewed a list of federally protected species for the Project from the
U.S. Fish and Wildlife Service's (USFWS) Information for Planning and Consultation
(IPaC) database (Appendix E). Table 4 lists the five federally protected species identified
by the USFWS IPaC for the Project.

Proposed Endangered. A taxon "is found to warrant listing as either threatened or endangered, or delisting, after completion
of a status review and consideration of other protective conservation measure
Candidate. A taxon "for which the USFWS has sufficient information on their biological status and threats to propose them as
endangered or threatened under the Endangered Species Act (ESA), but for which development of a proposed listing
regulation is precluded by other higher priority listing activities."
Endangered. A taxon "in danger of extinction throughout all or a significant portion of its range."
Threatened. A taxon "likely to become endangered in the foreseeable future throughout all or a significant portion of its
range."
HDR also queried the North Carolina Natural Heritage Program (NCNHP) Data Explorer
database for protected species Element Occurrence distribution and proximity to the
Project Area (Appendix E). The queries revealed that no known occurrences of federally
protected species or critical habitat have been documented within a one -mile radius of the
Project.

Charlotte -Mecklenburg Stormwater Services I Hinsdale-Tinkerbell SDIP
Pre -Construction Notification
The Project Area does not exhibit suitable habitat for the monarch butterfly, Michaux's
sumac, smooth coneflower, or Schweinitz's sunflower. Potential summer roosting habitat
for tricolored bat is present in forested areas of the site.
As a species proposed for listing as endangered, the prohibitions on "take" of the species
in Section 9 of the Endangered Species Act (ESA) do not apply to the tricolored bat. For
actions with federal agency involvement, such as this PCN request, the federal agency
(USACE) is required to confer with USFWS if the agency action is likely to jeopardize the
continued existence of the proposed species. Once the tricolored bat is listed, proposed
federal actions potentially affecting the bats will be subject to the ESA Section 9
prohibitions and Section 7 consultation requirements. The Service is not proposing to
designate critical habitat for the tricolored bat.
At the time of this submittal, the Project is not anticipated to have an effect on federally
protected species; however, defers to the lead federal agency (USACE) to confer with
USFWS.
compensatory Mitigation
Compensatory mitigation is not proposed for this project as the proposed permanent net
loss is 128 linear feet of stream channel. This project also proposes an improvement in
stream quality through channel stabilization and repairs using natural channel design
methods and bioengineering techniques.

Subject: APPROVAL of 401 Water Quality Certification with Additional Conditions
Hinsdale-Tinkerbell Stormwater Project
Dear Ms. Shanaberger:
You have our approval, in accordance with the General Certification and those
conditions listed below, for the purpose proposed in your application dated June 15, 2020, and
received by the Division of Water Resources (the Division) on July 1, 2020, and subsequent
information on July 28, 2020. After reviewing your application, we have determined that this
project is covered by Water Quality General Certification Number 4147 and 4133 which can be
viewed on our web site at https:Hdeg.nc.gov/about/divisions/water-resources/water-resources-
Permits/wastewater-branch/401-wetlands-buffer-permits/401-401-isolated-wetlands-waters-
program The General Certification allows you to use Nationwide Permit Number 3 and Regional
Permit 163 once they are issued to you by the U.S. Army Corps of Engineers (COE). Please
note that you should get any other federal, state or local permits before proceeding with your
project, including those required by (but not limited to) Sediment and Erosion Control, Non -
Discharge, and Water Supply Watershed regulations.
The above noted Certification will expire when the associated 404 permit expires unless
otherwise specified in the General Certification. It is advised that all conditions of the
Certification are reviewed prior to initiation of the project. In addition to the requirements of the
Certification, you must also comply with the following conditions:
This approval is only valid for the purpose and design that you described in your
application. If you change your project, you must notify us in writing, and you may be
required to send us a new application for a new Certification. If total wetland fills for this
project (now or in the future) exceed one acre, or of total impacts to streams (now or in
the future) exceed 300 linear feet, compensatory mitigation may be required. If the
property is sold, the new owner must be given a copy of the Certification and approval
letter; and is thereby responsible for complying with all conditions. 15A NCAC

4h. Explain the purpose of the proposed project:
The need for this project was identified through a project ranking process that involved analysis of customer
drainage requests, including complaints of house (finished floor) flooding, and road flooding. These
improvements also update and protect sanitary sewer infrastructure.
Through a channel assessment of the Project, Wildlands Engineering determined that a combination of channel
improvements were necessary to protect and stabilize eroding banks. This work will protect downstream stream
reaches from further degradation as the stormwater infrastructure system is upgraded. Any stream work will be
stabilized with coconut fiber matting, native riparian seeding, and live staking. The channel improvements are
also designed to protect buried and aerial sanitary sewer infrastructure.
This purpose of this project is to improve the storm drainage infrastructure to reduce roadway and structure
flooding within the Project. The purpose of this Pre -Construction Notificaiton (PCN) is to reauthorize previously
permitted impacts that will not be completed by the expiration date of the current General Permit (Nationwide and
Regional), add new impacts that have been completed that require after -the -fact authorization, and to add new
impacts that have not yet started.
4i. Describe the overall project in detail, including the type of equipment to be used:
The Hinsdale-Tinkerbell SDIP consists of a combination of closed pipe and open channel storm drainage
improvements designed to alleviate roadway and structure flooding within the Project. These improvements
include the replacement of four culverts, storm drainage outfall extensions, and the installation/replacement of rip
rap aprons. Additionally, channel realignment, stream grading, and bank stabilization was proposed utilizing
natural channel design methods and bioengineering techniques to prevent further channel degradation. During
this work, portions of existing sanitary sewer infrastructure were also upgraded and improved.
Existing culverts in the Project are either single barrel corrugated metal or single barrel reinforced concrete
culverts. These will be replaced with dual barrel culverts or bottomless culverts. Dual barrel culverts are designed
with a baseflow and a bankfull barrel to allow low flows while providing for increased capacity during flood
events; these culvert designs also help alleviate flow impoundment upstream of culvert crossings. The channel
grading upstream and downstream of the culverts will be required to tie the existing channel grades into the inlets
and outlets to achieve a stable transition. Impacts were reduced in the design by replacing two corrugated metal
pipes (CMPs) with bottomless culverts (at Hinsdale Street and Highview Road). The culvert replacement at
Hinsdale Street is complete, the culvert replacement at Highview Road is in construction, and the culvert
replacements at Champaign Street and Covered Bridge Lane have not started.
The channel realignment upstream of Highview Road that was proposed to alleviate the concerns of the right
bank eroding upslope and compromising a residential structure and sewer line has been completed. Constructed
riffles, log vanes, and bank and channel grading will correct channel dimensions utilizing natural channel design
methods. Channel grading and stabilization, and bank erosion repairs including associated dewatering activities
and construction access have been completed.
The existing sanitary sewer infrastructure in the vicinity of the Project also needed upgrades and flood protection.
There are a total of eight sewer crossings impacted by this Project, six of which are existing aerial sewer
crossings that will be replaced in the same footprint. Of the six aerial crossings, two will be buried via open cut
methods, while four will remain aerial. Additionally, two of the eight existing sewer crossings will be not be
replaced in the same footprint due to field conditions described below. All but one of the sewer crossings (Impact
41) have been completed.
All final hard stabilization and rip rap aprons proposed in the channels for the Hinsdale-Tinkerbell SDIP are
required for flood control capacity and the required minimal management of erosive velocities in the channels. All
of the proposed hard structure material is required to construct stable outfalls and transitions at new proposed
culvert/pipe locations.
Typical construction equipment includes excavators, backhoes, graders, skid -steer loaders, etc.
4j. Attach project drawings/site diagrams/depictions of impact areas for the proposed project.

E. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts through project design:
Impacts to on -site jurisdictional waters of the U.S. have been reduced to the maximum extent possible. The
project will comply with RGP Special and General Conditions, NWP Regional and General Conditions, and
Federal Emergency Management Act (FEMA) requirements.
Initially, the Hinsdale-Tinkerbell SDIP proposed extensive channel work downstream of Hinsdale Street.
However, as the result of an agency site visit with the USACE and DWR on September 5, 2018, bank
stabilizations were reduced to spot fixes only and stream grading was minimized to the maximum extent
practicable; thus, reducing the channel impacts to that which is reflected in the current plans. The reduction of
bank stabilization areas also minimizes tree clearing. Tree clearing has been reduced as much as possible to
retain existing stabilization along banks by natural woody vegetation.
Impacts were also reduced in the design by replacing two corrugated metal pipes (CMPs) with bottomless
culverts (at Hinsdale Street and Highview Road).
Proper sediment and erosion control measures are being used to minimize disturbances to downstream waters.
A pump around will be utilized to ensure that all work, including construction equipment, is conducted in the dry.
Temporary rock check dams and impervious dikes will be 6 feet in width, employed to protect downstream water
quality, and will be removed once construction is complete. Temporary stream crossings will be 12 feet in width
and will be removed once construction is complete; channel bed and banks will be returned to pre -construction
contours. Locations of temporary rock check dams, impervious dikes, and stream crossings will not be moved
once placed to avoid any additional tree clearing.
No impacts to wetlands are proposed.
1 b. Specifically describe measures taken to avoid or minimize proposed impacts through construction techniques:
As the result of an agency site visit with the USACE and DWR on September 5, 2018, bank stabilizations were reduced to spot fixes only and
stream grading was minimized to the maximum extent practicable; thus, reducing the channel impacts to that which is reflected in the current
plan. The reduction of bank stabilization areas also minimizes tree clearing. Locations of temporary rock check dams and stream crossings
will not be moved once placed to avoid any additional tree clearing.

Hi Crystal and Doug,
This email is to document my phone conversations with you both on Thursday, Sept 15 2022.
Blasting request for the remainder of the Hinsdale- Tinkerbell SDIP
I requested permission to blast bedrock on the remainder of the Hinsdale-Tinkerbell SDIP where it is
needed to install structures that have been authorized.
We are requesting blasting because we anticipate finding an unusually hard type of bedrock, similar
to that found at the Hinsdale culvert, in the remainder of the project. This bedrock is commonly
called blue stone granite and much more difficult to break with a hammer than the bedrock we
typically encounter in Charlotte. Because we were not allowed to blast at the Hinsdale culvert, we
used the largest hammer (350g) we could obtain without a licensed contractor and hammered at
the rock from April through mid -September to enable installation of structures as authorized. During
construction, four of these hammers broke and hydraulic lines broke approximately every other day.
Beyond the high cost of using this large hammer for five and a half months and the associated
problems, it was also extremely disruptive to residents and delayed completion of this culvert three
months beyond the original schedule.
Crystal said she did not see a problem with this and she would contact FWS with this request to fulfill
consultation requirements. Doug said he appreciated the notification and verbally approved.
Authorization for repairs downstream of the Hinsdale Culvert
I requested after -the fact authorization of impacts for repairs needed on the banks of the open
channel downstream of the Hinsdale Culvert. Total additional impacts for these repairs will add 28LF
of permanent non -loss and 14LF of temporary impacts.
We are requesting this authorization now because the contractor currently has equipment in the
area where repairs are needed, they plan to mobilize equipment away from this area soon, and the
entire project needs reauthorization to complete remaining work of the SDIP which will take some
time. The Hinsdale-Tinkerbell SDIP is authorized until 1/1/2023 because this is 12 months past the
date when RGP 163 was reissued. NWP 3 was reissued 3/19/2022. We plan to resubmit the project
for reauthorization before 1/1/2023 and will request include authorization for these repairs as part
of that application.
You both said that you were fine with permitting these additional impacts after -the -fact.
Impacts originally authorized and additional impacts for the proposed repairs are summarized

below:

In addition, Crystal reminded me to submit revised plans reflecting where impervious dikes where
used instead of the rock check dams in the reauthorization application.
Please let me know if you have any questions, and if you have corrections to the above summary of
our conversations or if you confirm it is accurate.
Thank you,

Subject: Hinsdale-Tinkerbell Storm Drainage Improvement Project
(SAW-2018-02116, DWR# 20-0788) - Change in locations for temporary impacts
Ms. Crystal Amschler and Mr. Alan Johnson:
I am writing to notify you of changes to the number and the locations of temporary measures (rock
check dams and stream crossings) constructed as part of the Hinsdale-Tinkerbell Storm Drainage
Improvement Project (SDIP) (SAW-2018-02116, DWR# 20-0788).
To avoid and minimize impacts, one temporary rock check dam was not constructed and the locations
for three temporary rock check dams and three temporary stream crossings were slightly altered. The
total amount of temporary impacts is less than what was authorized.
The Hinsdale-Tinkerbell SDIP was authorized for the following cumulative impacts:
Temporary Stream Impacts
554 linear feet
Proposed Permanent (non -Loss) Stream Impacts
1,861 linear feet
Proposed Permanent (Loss) Stream Impacts
116 linear feet
As part of the temporary stream impacts authorized, there were four temporary rock check dams and
three temporary stream crossings called out on plan sheet EC1. They were also summarized in the
Impacts Summary table starting on page 10 of the Pre -Construction Notification as follows.

One of the rock check dams listed above was not constructed and the locations for three temporary rock
check dams and three temporary stream crossings were adjusted to avoid trees, steep banks and/or
rock outcrops. Their revised locations as constructed are noted on the attached as -built map. As stated
in the pre -construction notification, all temporary rock check dams and stream crossings will be
removed once construction is complete, and the channel bed and banks will be restored to pre -
construction conditions.

IPaC resource list
This report is an automatically generated list of species and other resources such as critical
habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's
(USFWS) jurisdiction that are known or expected to be on or near the project area referenced
below. The list may also include trust resources that occur outside of the project area, but
that could potentially be directly or indirectly affected by activities in the project area.
However, determining the likelihood and extent of effects a project may have on trust
resources typically requires gathering additional site -specific (e.g., vegetation/species
surveys) and project -specific (e.g., magnitude and timing of proposed activities) information.
Below is a summary of the project information you provided and contact information for the
USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to
each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI
Wetlands) for additional information applicable to the trust resources addressed in that
section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis
of project level impacts.
The primary information used to generate this list is the known or expected range of each
species. Additional areas of influence (AOI) for species are also considered. An AOI includes
areas outside of the species range if the species could be indirectly affected by activities in
that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at
the dam site, may indirectly impact the species by reducing or eliminating water flow
downstream). Because species can move, and site conditions can change, the species on this
list are not guaranteed to be found on or near the project area. To fully determine any
potential effects to species, additional site -specific and project -specific information is often
required.
Section 7 of the Endangered Species Act requires Federal agencies to "request of the
Secretary information whether any species which is listed or proposed to be listed may be
present in the area of such proposed action" for any project that is conducted, permitted,
funded, or licensed by any Federal agency. A letter from the local office and a species list
which fulfills this requirement can only be obtained by requesting an official species list from
either the Regulatory Review section in IPaC (see directions below) or from the local field
office directly.
For project evaluations that require USFWS concurrence/review, please return to the IPaC
website and request an official species list by doing the following:
1. Draw the project location and click CONTINUE.
2. Click DEFINE PROJECT.
3. Log in (if directed to do so).
4. Provide a name and description for your project.
5. Click REQUEST SPECIES LIST.
Listed speciesi and their critical habitats are managed by the Ecological Services Program of
the U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic
and Atmospheric Administration (NOAA Fisheries).
Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown
on this list. Please contact NOAA Fisheries for species under their jurisdiction.
1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also
shows species that are candidates, or proposed, for listing. See the listing status page for
more information. IPaC only shows species that are regulated by USFWS (see FAQ).

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 (■)
Oft . 4w\4.
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.
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 0.2Sf0.2S = 1; at week 20 it is O.OSi0.2S = 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.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
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 ( )

12/21/22, 10:10 AM
IPaC: Explore Location resources
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.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
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.

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 list of migratory birds that potentially occur 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.
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 Rapid Avian Information Locator (RAIL) 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 or migrating in my 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 query your location using the RAIL Tool and look at the range maps
provided for birds in your area at the bottom of the profiles provided for each bird in your results. 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:

12/21/22, 10:10 AM
IPaC: Explore Location resources
"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.

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 BirdBird Studv and the nanotag studies or contact
Caleb Spiegel or Pam Loring.
X041111*
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

IPaC: Explore Location resources
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level
information on the location, type and size of these resources. The maps are prepared from the analysis of
high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A
margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any particular
site may result in revision of the wetland boundaries or classification established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image
analysts, the amount and quality of the collateral data and the amount of ground truth verification work
conducted. Metadata should be consulted to determine the date of the source imagery used and any
mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There
may be occasional differences in polygon boundaries or classifications between the information depicted
on the map and the actual conditions on site.
Data exclusions
-0-N
Certain wetland habitats are excluded from the National mapping program because of the limitations of
aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or
submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and
nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also
been excluded from the inventory. These habitats, because of their depth, go undetected by aerial
imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe
wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or
products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local
government or to establish the geographical scope of the regulatory programs of government agencies.
Persons intending to engage in activities involving modifications within or adjacent to wetland areas should
seek the advice of appropriate Federal, state, or local agencies concerning specified agency regulatory
programs and proprietary jurisdictions that may affect such activities.

Dear Johanna Velasquez:
D. Reid Wilson, Secretary

Deputy Director, Natural Heritage Program
NCN H DE-20336
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
