1.0 Introduction
This report presents the findings of a natural resources assessment performed by HDR for Duke
Energy Progress (Duke Energy) for the proposed Cary Regency Park – RTP 230kV Relocate Line
Structure 109 Project (Project), located in Wake County, North Carolina. The proposed Project is
located along approximately 0.35 miles of existing transmission line right-of-way within the town of
Morrisville. The Study Area as referenced in this report comprises approximately 3.98 acres.
HDR’s approach to this assessment involved a desktop review of publicly available data and an on-
site investigation that included surveys for wetlands and jurisdictional waters of the U.S., federally
protected species habitat, and classification of natural/vegetation communities. The following
sections provide a summary of HDR’s methods and findings of the desktop analysis and on-site
environmental surveys. Attached to this report are supporting figures (Appendix A), North Carolina
Office of State Archaeology (OSA) Site Form (Appendix B), stream identification forms (Appendix C),
a North Carolina Natural Heritage Program (NCNHP) Project Report and Information for Planning
and Consultation (IPaC) Resources List (Appendix D), and site photographs (Appendix E).
2.0 Description of Study Area
The Study Area is located on an existing transmission line that begins at Structure 108 (35.817987,
-78.839642) near Millet Drive and terminates at Structure 111 (35.816447, -78.835753) in Wake
County, North Carolina (Appendix A, Figures 1 and 2). Land use in the vicinity of the proposed
Project and within the Study Area mainly consists of developed residential communities, forested
land, and existing transmission right-of-way.
The Study Area is situated in the town of Morrisville, approximately 5.5 miles northwest of Cary,
North Carolina. The topography in the vicinity of the Study Area consists of rolling hills with broad,
level floodplains along streams, typical of the Piedmont region (Appendix A, Figure 3).
3.0 Desktop Analysis
HDR conducted a desktop review of publicly available data from federal and state agencies prior to
engaging in field reconnaissance surveys. The following sources were consulted as part of this
analysis:

3.1 NRCS Soils
The NRCS Soil Survey of Wake County, North Carolina, identifies two different soil types within the
Study Area (Appendix A, Figure 4). The NRCS’s National Hydric Soils List classifies Chewacla and
Wehadkee soils as hydric. A summary of the soil types located within the Study Area is provided in
Table 1.

3.2 Land Cover
HDR reviewed the land cover layer of the MRLC’s NLCD to identify existing land cover
classifications within and immediately adjacent to the Study Area. Land use in the area is classified
as developed (open space and low intensity) (Appendix A, Figure 5).
3.3 Cultural Resources
HDR reviewed the National Park Service NRHP GIS Public Dataset, the NCHPO HPOWEB GIS
Web Service as well as the North Carolina Office of State Archaeology (OSA) in-house datasets.
There are no known archaeological resources, historic structures, or historic districts located within
or around a half-mile radius of the Study Area (Appendix A, Figure 6). The OSA in-house dataset
found one site within a half-mile radius of the Study Area that is prehistoric and “Unassessed”
(Appendix B). HDR recommends coordinating with the NCHPO and OSA regarding potential issues
with respect to archaeological resources that are located near the Study Area.

3.4 Federally Protected Species
HDR obtained and reviewed a list of federally protected species for Wake County from the USFWS
website (updated on June 27, 2018) and generated an IPaC resources list for the Study Area
(Appendix D). A summary of these species is provided in Table 2.

T = threatened. A taxon “likely to become endangered within the foreseeable future throughout all or a significant portion of its
range.
2 Current = the species has been observed in the county within the last 50 years.
* Study Area not located in species-preferred watershed.
HDR queried the NCNHP Data Explorer database for protected species element occurrence
distribution and proximity to the Study Area (Appendix D, Project Report [NCNHDE-10366]). The
NCNHP Project Report summarizes occurrences of federally and state-protected species, critical
habitat, and managed areas that have been documented within a one-mile radius of the Study Area.
These records indicate that no element occurrences of federally protected species are present within
the Study Area.
The NCNHP Data Explorer query also revealed that no federally listed species or natural areas were
documented within a one-mile radius of the Study Area. Federally protected species descriptions
and habitat requirements for Wake County, including the results from the on-site field
reconnaissance activities, are detailed in Section 4.4.
3.5 Managed Lands Assessment
HDR obtained and reviewed the NCNHP Managed Areas GIS Dataset, which was last updated in
April 2019. Managed areas associated with the Town of Morrisville Open Space – Morrisville
Community Park are located within the Study Area (Appendix A, Figure 7). Twenty-four (24) other
managed areas were documented within a one-mile radius of the Study Area.
3.6 FEMA Floodplains and Regulated Riparian Buffers
HDR reviewed the FEMA Map Service Center National Flood Hazard Layer (NFHL) and found that
Special Flood Hazard Areas (SFHAs) do not extend into the Study Area (FEMA Map Number
3720074500J (Appendix A, Figure 8)); and the Study Area is within an “Area of Minimal Flood
Hazard” as shown on Appendix A, Figure 8 (FEMA 2019). Areas of minimal flood hazard are defined
Cary Regency Park – RTP 230kV Relocate Line Structure 109 Project
Natural Resources Assessment-REVISED

4
as being outside the 0.2 percent annual chance floodplain. HDR also reviewed regulated riparian
buffers at the state, county, and municipal levels, as described below.
3.6.1 North Carolina State Surface Water Buffers
The North Carolina Division of Water Resources (NCDWR) implements watershed riparian buffers
within six watersheds in North Carolina: the Catawba River Basin, the Goose Creek Watershed, the
Jordan Lake Watershed, the Neuse River Basin, the Tar-Pamlico River Basin, and the Randleman
Lake Watershed. Each buffer rule is specific to the waters it protects and cannot be used
interchangeably. The Study Area is located within the Neuse River Basin (Upper Middle Creek,
030202010901), and is therefore subject to the Neuse River Basin Riparian Buffer Rule.
The Neuse River Basin Riparian Buffer Rule (the Rule) requires local governments to ensure that
riparian areas are protected on new developments in accordance with the Riparian Buffer Rule (Rule
15A NCAC 02B .0233 [General Assembly North Carolina 2000]). This Rule applies to existing 50-
foot-wide riparian buffers directly adjacent to surface waters in the Neuse River Basin (intermittent
streams, perennial streams, lakes, ponds, and estuaries), excluding wetlands that are illustrated on
either the most recent version of the NRCS Soil Survey Map or USGS topographic quadrangle. No
surface waters within the Study Area are depicted on the most recent USGS topographic
quadrangle. A tributary to Crabtree Creek is (Stream 1) is depicted on the 1970 Soils Survey of
Wake County North Carolina, Map Sheet 46 (Appendix A, Figure 9) and may be subject to the Rule
(Cawthorn 1971).
Per 15A NCAC 02B .0233 (3), the protected riparian buffer for intermittent streams has two zones:
Zone 1 shall begin at the most landward limit of the top of bank or the rooted herbaceous vegetation
and extend landward a distance of 30 feet on all sides of the surface waters, measured horizontally
on the line perpendicular to the surface waters. Zone 2 be shall begin at the outer edge of Zone 1
and extend landward 20 feet as measured horizontally on a line perpendicular to the surface waters.
The combined width of Zone 1 and Zone 2 shall be 50 feet on all sides of the surface water.
A complete list of allowable activities within the regulated buffer as exempt, allowable with mitigation,
or prohibited can be found in 15A NCAC 02B .0233(6) Table of Uses. Potential impacts may need
authorization under NCDWR’s Buffer Permitting Branch program.
3.6.2 Wake County Surface Water Buffers
Wake County Water Supply Watershed Buffers are applicable to all watercourses and
impoundments in the R-80W, R-40W, WPO-2NC, WPO-3NC, WPO-4P-1, and WPO-4P-2 zoning
districts. The Study Area is not within these zoning districts; therefore, no Wake County surface
water buffer requirements apply.
3.6.3 Municipal Surface Water Buffers
The Town of Morrisville’s jurisdictional waters are regulated by the Neuse River Basin Buffer Rule.
No additional municipal surface water buffer requirements apply.
4.0 Field Reconnaissance
4.1 Wetlands and Jurisdictional Waters of the U.S.
On September 27, 2019, HDR biologists surveyed the Study Area for wetlands and jurisdictional
waters of the U.S. regulated under Section 404 of the Clean Water Act (CWA). The assessment was

conducted according to the methodologies and guidance described in the U.S. Army Corps of
Engineers (USACE) 1987 Wetland Delineation Manual, USACE Post-Rapanos guidance, USACE
Eastern Mountain and Piedmont Regional Supplement (USACE 2010), and the NCDWR
Methodology for Identification of Intermittent and Perennial Streams and Their Origins (Version 4.11)
(NCDWQ 2010). Jurisdictional waters of the U.S. were delineated (flagged in the field) and mapped
using a Trimble® Geo7X GPS unit capable of sub-meter accuracy. GPS points were post-processed
utilizing Trimble® GPS Pathfinder Office software.
On-site reconnaissance activities identified one jurisdictional intermittent stream. No wetlands or
open waters were identified (Appendix A, Figure 10). A summary of the identified jurisdictional
feature is provided in Table 3.

-78.839474 3.0-4.0 719 3.0-10.0
4.1.1 Description of Waters of the U.S.
Stream 1, a tributary to the Crabtree Creek, was identified as Relatively Permanent Waters (RPWs)
that exhibits seasonal surface water flow to Traditional Navigable Waters (TNWs). According to the
Cowardin Classification hierarchical structure (Cowardin et al. 1979), Stream 1 is classified as a
riverine, intermittent feature with a cobble-gravel streambed (R4SB3).
Ordinary High Water Mark (OHWM) indicators observed during the assessment included well-
defined, natural lines impressed on the banks; shelving; matted down, bent, or absent vegetation;
disturbed or washed away leaf litter; and sediment sorting.
4.2 Natural Communities
According to the Classification of the Natural Communities of North Carolina – Fourth Approximation
(Schafale 2012), no natural communities were identified within the Study Area (Appendix A, Figure
7). The area is primarily maintained/developed along the existing transmission line corridor.
Vegetation in the maintained area consists of early successional species such as sawtooth
blackberry (Rubus argutus), dogfennel (Eupatorium capillifolium), seedbox (Ludwigia alternifolia),
hop sedge (Carex lurida), common rush (Juncus effusus), sweet-gum (Liquidambar styraciflua),
water oak (Quercus nigra), red maple (Acer rubrum), and greenbrier (Smilax rotundifolia).
4.3 Terrestrial Wildlife
Terrestrial communities in the Study Area are comprised of forested habitats that may support a
diverse number of wildlife species. Representative mammal, bird, and reptile species commonly
occurring in these habitats are listed below. Note individual species and/or evidence of species
observed during HDR’s field survey are indicated with an asterisk (*). Information on species that
typically use these habitats in the ecoregion was obtained from relevant literature, mainly the
Biodiversity of the Southeastern United States, Upland Terrestrial Communities (Martin et al. 1993).
Mammal species that commonly occur in these habitats include eastern cottontail (Sylvilagus
floridanus); coyote (Canis latrans); gray squirrel (Sciurus carolinensis); white-tailed deer (Odocoileus
virginianus); and various vole, rat, and mice species*. Bird species that commonly use these habitats

include American crow (Corvus brachyrhynchos), northern cardinal (Cardinalis cardinalis), mourning
dove (Zenaida macroura), eastern towhee (Pipilo erythrophthalmus), and northern mockingbird
(Mimus polyglottos). Predatory birds may include red-shouldered hawk (Buteo lineatus), red-tailed
hawk (Buteo jamaicensis), owl species, and Eastern wild turkey (Meleagris gallopavo). Reptile
species that may use this terrestrial community include the eastern corn snake (Pantherophis
guttatus), copperhead (Agkistrodon conttortrix), eastern box turtle (Terrapene carolina carolina),
banded water snake (Nerodia fasciata), and brown water snake (Nerodia taxispilota).
4.4 Federally Protected Species
HDR’s on-site survey also served to identify potential habitat and possible individuals of federally
protected species listed in Table 2 for Wake County. The following is a summary of habitat
descriptions and the presence/absence of habitat within the Study Area for species that are federally
protected under the Bald and Golden Eagle Protection Act (BGEPA) and/or the provisions of Section
7 and Section 9 of the Endangered Species Act of 1973.
4.4.1 Vertebrates
Cape Fear shiner (Notropis mekistocholas) [Federally Endangered]
USFWS Recommended Survey Window: April – June (tributaries); year round (large rivers)
Habitat Description: The Cape Fear shiner is known to occur only in the Cape Fear River watershed.
In general, habitat includes streams with clean gravel, cobble, or boulder substrates. The Cape Fear
shiner is most often observed inhabiting slow pools, riffles, and slow runs associated with water
willow (Justicia americana) beds, which it uses for cover. Juveniles can be found inhabiting
slackwater, among large rock outcrops, and in flooded side channels and pools. Spawning occurs
from May through June, when water temperatures reach 66 degrees Fahrenheit (USFWS 2006).
Biological Conclusion: No effect. The Study Area is not within the Cape Fear River watershed. No
impacts to this species are anticipated.
Red-cockaded woodpecker (Picoides borealis) [Federally Endangered]
USFWS Recommended Survey Window: year round; November – early March (optimal)
Habitat Description: The red-cockaded woodpecker (RCW) typically occupies open, mature stands
of southern pines, particularly longleaf pine (Pinus palustris), for foraging and nesting/roosting
habitat. The RCW excavates cavities for nesting and roosting in living pine trees, aged 60 years or
older, which are contiguous with pine stands at least 30 years of age to provide foraging habitat. The
foraging range of the RCW is typically no more than 0.5 miles (USFWS 2016).
Biological Conclusion: No effect. Suitable habitat for this species was not observed within the Study
Area. In addition, no RCW element occurrences are within the Study Area. No impacts to this
species are anticipated.
Bald eagle (Haliaeetus leucocephalus) [Federally Protected under BGEPA]
USFWS Recommended Survey Window: October 1 – May 15
Habitat Description: Bald eagles occur throughout much of the continental U.S. and Canada. The
species frequently builds their nests in live pines or cypress trees near large bodies of open water
and may congregate around fish processing plants, dumps, and below dams where fish tend to
school in groups. Nests typically measure 6 to 8 feet deep and 6 feet in diameter and are cone
shaped. Bald eagles are opportunistic feeders and consume a variety of prey that has been self-

Natural Resources Assessment-REVISED

7
caught, scavenged, or robbed from other bird species. The threat to this species is attributed to
disturbance and destruction of foraging and nesting habitat by urban and residential development
(USFWS 1978). According to the NCNHP Element Occurrence Database, no bald eagle
occurrences have been documented in or within one mile of the Study Area.
Biological Conclusion: No effect. The Study Area is located within one mile of open water, but did not
exhibit any suitable nesting trees for bald eagle; therefore, no impacts to this species are anticipated.
4.4.2 Invertebrates
Dwarf wedgemussel (Alasmidonta heterodon) [Federally Endangered]
USFWS Recommended Survey Window: year round
Habitat Description: In North Carolina, the dwarf wedgemussel occurs in the Neuse and Tar River
drainages. The mussel inhabits creeks and rivers with a slow to moderate current and sand, gravel,
or firm silt bottoms. Water in these areas must be well oxygenated and stream banks are generally
stable with extensive root systems holding soils in place (USFWS 2017a).
Biological Conclusion: No effect. There are no element occurrences within the Study Area, and
there were no occurrences of Dwarf wedgemussel observed within the Study Area during the field
survey. No impacts to this species are anticipated.
Tar River spinymussel (Parvaspina steinstansana) [Federally Endangered]
USFWS Recommended Survey Window: year round
Habitat Description: The Tar River spinymussel is endemic to the Tar and Neuse River drainage
basins in North Carolina. This mussel requires a stream with fast flowing, well-oxygenated water with
circumneutral pH and stream bottoms composed of unconsolidated gravel and coarse sand. The
water needs to be relatively silt-free, and stream banks should be stable, typically with many roots
from adjacent riparian trees and shrubs (USWFS 2011).
Biological Conclusion: No effect. The Study Area is not within the Tar River watershed. No impacts
to this species are anticipated.
Yellow lance (Elliptio lanceolata) [Federally Threatened]
Habitat Description: The yellow lance is a sand-loving freshwater mussel often found buried deep in
clean, coarse to medium sand, although it can sometimes be found in gravel substrates. Yellow
lances often are moved with shifting sand and eventually settle in sand at the downstream end of
stable sand and gravel bars. This species depends on clean, moderate flowing water with high
dissolved oxygen and is found in medium-sized rivers to smaller streams (USFWS 2019).
Biological Conclusion: No effect. The Study Area is not within the species preferred watershed. No
suitable habitat exists within the Study Area. No impacts to this species are anticipated.
4.4.3 Vascular Plants
Michaux's sumac (Rhus michauxii) [Federally Endangered]
USFWS Optimal Survey Window: May – October
Habitat Description: Michaux’s sumac, endemic to the inner Coastal Plain and lower Piedmont,
grows in sandy or rocky, open, upland woods on acidic or circumneutral, well-drained sands or
sandy loam soils with low cation exchange capacities. The species of plant is also found on sandy or
submesic loamy swales and depressions in the fall line Sandhills region as well as in openings along
Cary Regency Park – RTP 230kV Relocate Line Structure 109 Project
Natural Resources Assessment-REVISED

the rim of Carolina bays; maintained railroad, roadside, power line, and utility rights-of-way; areas
where forest canopies have been opened up by blowdowns and/or storm damage; small wildlife food
plots; abandoned building sites; under sparse to moderately dense pine or pine/hardwood canopies;
and in and along edges of other artificially maintained clearings undergoing natural succession. In
the central Piedmont region, it occurs on clayey soils derived from mafic rocks. The plant is shade
intolerant, and therefore grows best where disturbance (e.g., mowing, clearing, grazing, periodic
fires) maintains an open habitat (USFWS 2017b).
Biological Conclusion: No effect. Suitable habitat for this species was observed within the Study
Area; however, no individual species were observed during the field survey. No impacts to this
species are anticipated.
5.0 Conclusion
Results from HDR’s desktop analysis and on-site field reconnaissance indicate that the proposed
project may affect natural resources including jurisdictional waters and regulated riparian buffers
within the Study Area.
The assessment identified one intermittent stream within the Study Area. Depending on the final
project design, a Section 404 Permit and a 401 Water Quality Certification may be required if
potential impacts to onsite waters of the U.S. are unavoidable. The USACE Nationwide Permit 12
(Utility Lines Activities) is expected to be the applicable permit since the proposed project may
involve construction, maintenance, or repair, and removal of a utility lines and associated facilities
that may result in minimal temporary or permanent fill impacts to waters of the U.S. The USACE
ultimately decides what permit will be required to authorize project construction.
Riparian buffers along the tributary to Crabtree Creek are subject to Neuse River Buffer Rules.
Potential impacts may require a 401 riparian buffer authorization from the NCDWR.
Suitable habitat exists within the Study Area for Michaux’s sumac; however, on-site surveys found
no individuals of it, therefore, no impacts are anticipated. HDR recommends coordination with the
USFWS concerning an official determination for these species.
The OSA in-house dataset found one site within a half-mile radius of the Study Area that is
prehistoric and “Unassessed.” HDR recommends coordinating with the NSHPO and OSA regarding
potential issues with respect to archaeological resources that may be located within and near the
Study Area.

RE: Cary Regency Park
Dear Jessica Tisdale:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached ‘Documented Occurrences’ tables and map.
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 documented within the project area or 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.
Also please note that 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 an occurrence of a Federally-listed species is 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 [e-mail] or 919-707-8603.
Sincerely,
NC Natural Heritage Program
Natural Heritage Element Occurrences, Natural Areas, and Managed Areas Intersecting the Project Area

No Element Occurrences are Documented within the Project Area
There are no documented element occurrences (of medium to very high accuracy) that intersect with the project area. Please note, however, that although the
NCNHP database does not show records for rare species within the project area, it does not necessarily mean that they are not present; it may simply mean that
the area has not been surveyed. The use of Natural Heritage Program data should not be substituted for actual field surveys if needed, particularly if the project
area contains suitable habitat for rare species. If rare species are found, the NCNHP would appreciate receiving this information so that we may update our
database.

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
.
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.
2.NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an office of the
National Oceanic and Atmospheric Administration within the Department of Commerce.
The following species are potentially affected by activities in this location:

Potential effects to critical habitat(s) in this location must be analyzed along with the endangered
species themselves.
THERE ARE NO CRITICAL HABITATS AT THIS LOCATION.
Migratory birds
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.

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
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 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 (BCC)and other species that
may warrant special attention in your project location.
.
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 birds that may be helpful to you in your project review.

Data exclusions
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.
