4. Project Description and History
4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:*
The project area is located within the Grandfather Golf and Country Club. Loch Donnie is a manmade impoundment on the Linville River, a designated public mountain trout stream.
Loch Donnie and the Linville River within the project area has accumulated a significant amount of sediment due to years of deposition. There are six uninhabited islands and one
inhabited island within Loch Dornie that are experiencing bank erosion on steep banks. There are seven pedestrian bridges within the project area; two of the bridges support sanitary
sewer lines, which are hung on the substructure of the bridges. One of the bridges has been closed due to imminent risk of catastrophic failure. The closed bridge is one of the two
bridges that supports a sanitary sewer. Failure of the bridge structure would result in loss of the supported sewer and spillage of raw sewage into the Linville River.
Land use of the project vicinity includes the golf course, administrative and recreational buildings associated with the golf course and country club, other recreational areas, residential
properties, and undeveloped forested areas. Recreational facilities and areas include a clubhouse, maintained lawn areas, a beach area adjacent to Loch Dornie, and a walking path.
Residential development includes single-family and multi -family units around Loch Dornie and multi -family units on the inhabited island in Loch Dornie.

4h. Explain the purpose of the proposed project:*
The primary purposes of the project are (1) to dredge accumulated sediments from the Linville River and Loch Dornie, (2) to improve unstable river banks and lake shoreline areas, (3)
replace pedestrian bridges that have become unsafe and hazardous, and (4) protection of sanitary sewer assets. Secondary purposes include (5) enhancing the lake shoreline, (6)
improving safety and enjoyment for pedestrians, and (7) reduce future maintenance needs.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The proposed project is located within the Grandfather Golf and Country Club (GGCC), which is located along Highway 105 South, southwest of Boone, and north of Linville. The
project is located within parcels owned by GGCC, the GGCC Common Area for Condos Wilmor Corp, and one private owner. Within the project area, jurisdictional waters of the US
consist of the Linville River and an impoundment of the Linville River, herein referred to as Loch Dornie. The Linville River, including Loch Dornie, is a designated public mountain trout
water.
The proposed project consists of numerous enhancements within the GGCC property. The primary goal of the project is to remove accumulated sediments from within Loch Dornie and
the Linville River channel while providing bank and shoreline stabilization. The project components include dredging accumulated sediments, reconstruction of uninhabited islands in
Loch Donnie, removal of seven pedestrian bridges and replacement of five of the seven bridges, sanitary sewer replacement and protection, bank and shoreline stabilization,
construction of a new event lawn and pedestrian path, and erosion and sediment control measures in the environmental release channel (Figure 4).
Loch Donnie has received sediments from areas upstream of the GGCC property that have been transported by the Linville River and deposited in the lake when water flows slowed.
The sediments are proposed to be dredged from the lake and reused onsite for shoreline stabilization. Additionally, in the upper portion of the lake, Loch Dornie is split into narrow lake
canals that are referred to as the "east channel' and the "west channel'. At the split, a large amount of cobble has been deposited by the river and is altering the flow patterns in the two
lake channels, occasionally eliminating flows in the east channel. The cobble is proposed to be removed by dredging and reused onsite for shoreline stabilization.
Currently, there are six uninhabited islands in Loch Donnie. These islands are proposed to be removed or modified as part of the project. The uninhabited islands are characterized by
deteriorating shorelines. Four of the six islands are currently connected by pedestrian footbridges (Bridges A through E). GGCC proposes to remove or modify the six uninhabited
islands and construct two new uninhabited islands in approximately the same location in Loch Dornie. The two new, larger islands will be connected by three new pedestrian footbridges
(Proposed Bridge #1, #2, and #3). The footbridges will be made of fiber reinforced plastic (FRP) with concrete bridge abutments at each end. Bridges #1 and #2 will span the waterway
and avoid permanent impacts to the lake and lakebed. Bridge #3 will consist of three 60 -foot long sections that will require two support piers to be constructed in the lake. Three options
for the piers have been designed; the option selected shall depend on the foundation conditions encountered during construction. Dependent upon geotechnical conditions, the piers
Wil consist of either treated wooden piles driven to depth adequate for support, or concrete supports or wooden piles anchored into a cast -in-place concrete. The two piers are
assumed to be 15 feet tall and 2.5 to 2.5 feet wide. The long dimension will be 9.5 feet at the top and roughly 18 feet at the base. The dimensions of two cast -in-place concrete bases to
establish a level foundation for each pier are assumed to be 22 feet long, 7 feet wide, and 2 feet deep.
The new islands will be constructed with gentler sloping shorelines that are designed to be more stable and withstand greater sheer stresses than the current shorelines. Fill materials
used to construct the two new islands are anticipated to consist of suitable dry borrow material, dredged lakebed and cobble materials from within the project area. The shorelines will
be landscaped and planted to improve the resiliency and stability of the new land surface. The large island is proposed to be 0.61 acre in size, and the small island is proposed to be
0.26 acre in size.
Within the project area, there are a total of seven existing pedestrian bridges (Bridges A through G). Five of the existing bridges (Bridges A through E) connect land on either side of
Loch Dornie with the aforementioned five uninhabited islands. Bridge F connects land along the western shore of Loch Dornie with the inhabited island that is situated between the west
and east channels of the upper Loch Dornie. Bridge G spans the Linville River immediately upstream of the west and east channel split. Bridge G has been closed to users due to its
lack of structural integrity and severe risk of structural failure. Bridges F and G are proposed to be replaced. Bridge F is proposed to be replaced in place with Bridge #4. Bridge G is
proposed to be replaced by Bridge #5 and will be adjusted slightly from the alignment of the existing bridge in order to simplify sanitary sewer reconnection.
There are three segments of sanitary sewer pipes that need replacement or protection. Two segments are currently attached to the substructure of Bridges F and G described in the
preceding paragraph. These two sanitary sewer pipes will be replaced in-kind and in similar fashion. The new sewers will be attached to the substructure of the new bridges. As the
alignment and length of Bridge F is to remain unchanged, the associated 6 -inch diameter sewer will also be replaced with the same length of pipe as is present. As Bridge G will be
realigned from its current position, the associated 8 -inch diameter sewer will likewise be extended. With 96 feet of existing sewer being replaced with 105 feet of new sewer. The third

sanitary sewer segment is proposed to be protected. The third segment consists of an exposed pipe crossing the Linville River in the northern most portion of the project area.
Protection of the sewer is proposed to be accomplished by construction of a grade control sill (GCS) around the pipe. The GCS consists of rock that will be placed to protect the 8 -inch
diameter pipe across the full width of the river.
Bank and shoreline stabilization measures are proposed along reaches of the Linville River, the east and west lake channels of Loch Dornie, and Loch Dornie. A total of eight locations
are proposed for bank or shoreline stabilization, not including the previously described island construction and associated shoreline stability design. Bank stabilization (BS) #1 is located
within the Linville River in the upstream most portion of the project area. BS #1 consists of construction of a 208 foot long imbricated rock wall along the west bank of the river, regrading
the east bank of the river to create a floodplain bench, and installation of 5 GCSs in the bed of the river. BS #2 is Ionated along the west bank of the Linville River immediately
downstream of Bridge G. The BS #2 location is immediately upstream of the transition from flowing river to impounded open water area. Stabilization of the BS #2 site consists of
constructing an imbricated rock wall along 80 feet of the west bank of the river that will tie into an existing stacked rock wall and will match the existing bank surface. The imbricated rock
wall is needed to provide structural support to a very steep bank adjacent to a building. BS #2 will also protect the new bridge and sanitary sewer manhole from hazards associated with
future erosion of the stream bank.
BS #3 and #4 are associated with the shoreline along the inhabited island in Loch Dornie. BS #3 is located along the west bank of the east lake channel. The BS #3 site has nearly
vertical banks and is at high risk of undermining the structural integrity of private residences on the island if left in its current condition. BS #4 is located along the south bank of the
inhabited island and is located where the east and west lake channels converge in Loch Dornie. Due to the current geometry and location of the bank at the BS #4 site, the conditions
are appropriate to allow the development of eddies during times of high flows. BS #4 is needed to protect private residential structures, provide increased shoreline stability, and
improve accessibility and safety along the south end of the inhabited island.
BS #5 and #6 are located along the western shore of Loch Dornie. BS #5 consists of construction of a littoral shore and retention of the existing location of the lake's edge of water. BS
#6 includes backfilling the site to smooth the line of the shore and reduce shoreline slope to reduce the risk of future erosive forces along the segment of shoreline. BS #6 involves
shifting the edge of water eastward.
BS #7 and #8 are located along the eastern shore of Loch Dornie. BS #7 is located near the downstream end of the east lake channel of upper Loch Dornie. BS #7 is triangular in
shape and shows evidence of ongoing erosion of the existing shoreline. The area has a history of maintenance issues, primarily related to the steep slope above normal pool elevation
and the frequent sediment deposition. The area is proposed to be backfilled, shifting the edge of water to the southwest. Within the BS #7 area, an existing stormwater pipe discharges
into Loch Dornie. The pipe is proposed to be extended by 105 feet through the area to be backfilled in order to retain the existing discharge into the lake. BS #4, #6, and #7 have been
designed to encourage water movement that is anticipated to promote self -maintenance of the newly dredged areas, thereby reducing future maintenance needs.
BS #8 is located adjacent to the existing clubhouse on the eastern shore of the lake. The shoreline at the BS #8 site is proposed to be extended into the lake. The northern portion of
the BS #8 site is to be graded with gentler slopes than are currently present, and the southern section of BS #8 site is proposed to be stabilized with a concrete retaining wall. The area
around BS #8 is often used by residents and visitors to GGCC and presents a hazard due to the steep, abrupt slopes and ongoing erosion. The design of BS #8 provides for shoreline
stabilization and pedestrian safety as well as the construction of an event lawn. The event lawn will provide an outdoor space for recreation and gatherings with the scenic lake as a
backdrop.
The proposed enhancements of the GGCC property include path improvements for an approximately 1,300 -foot long, 6 -foot wide pedestrian path along the west side of Loch Dornie.
The current path is maintained grass, follows the existing sanitary sewer alignment and is occasionally used for maintenance access. The proposed pedestrian path improvements will
connect the club's administrative offices, fitness center and recreation area to multiple residences and condos surrounding upper Loch Dornie as well as the island bridges that connect
over to the clubhouse. An additional 200 feet of pedestrian path improvements will connect Loch Dornie Drive to proposed Bridge#4 and extend briefly east of Bridge #4 on the
inhabited island. The path is proposed to consist of compacted subgrade with 4 -inch deep compacted aggregated base topped with 4 -inch thick granite screenings. The edges of the
path will be maintained in perpetuity by 6 -inch tall aluminum edging that will be held in place by 12 -inch long aluminum stakes. Presently, pedestrians share the paved roadways with
vehicular traffic. The roads are two-lane facilities with narrow, vegetated shoulders, presenting a safety concern for pedestrians. The proposed pedestrian path will provide a safe
alternative to sharing the road as well as a more scenic, aesthetically pleasing route.
Loch Dornie discharges water over the spillway, located at the southeastern corner of the lake, and through an environmental release pipe. GGCC is required to maintain a minimum
flowthrough the environmental release pipe to support aquatic life in the Linville River downstream of the Loch Dornie dam. To accommodate the proposed in -water work of the project,
the lake will be drawn down to establish dry work areas, which will result in no water passing over the spillway and the only flows from the lake being through the environmental release
pipe. Water diversion and erosion and sedimentation control measures will be in place to protect water quality. During large storm events, however, water in the lake is expected to rise
and be characterized in higher than normal turbidity due to suspended sediments. In order to protect downstream water quality during the lake draw -down period, the project also
includes an additional level of treatment that is the placement of erosion and sediment control measures below the dam in the environmental release channel. These measures consist
of floc logs or blocks to introduce polyacrylamide and coir log rolls to trap suspended sediments.
Erosion and sediment control measures will be implemented and maintained in good condition throughout the construction period. Measures shall include silt fencing along the
downgradient limits of disturbance, turbidity curtains in Loch Dornie immediately downstream of the work areas and immediately upstream of the spillway, and floc logs and coir log rolls
in the environmental release channel. Additionally, all work conducted in the river or lake will be performed in dry work conditions. The river will be diverted away from active construction
areas and will be conveyed via gravity diversion pipes as needed to ensure dry work zones. The lake will be drawn down at the commencement of construction in order to establish dry
work areas to accommodate the proposed lake dredging, island reconstruction, and shoreline stabilization.
Construction access to the construction area will be provided by the existing roads at the GGCC. Vehicular and equipment access within the limits of disturbance shall be provided via
existing access paths, stabilized construction entrances, and temporary access paths. The temporary access paths are proposed to be constructed of Geoterra structural mats or
similar construction matting. The access paths will generally be 12 feet wide and located in upland areas. Four points of direct stream or lake access or crossing are proposed along the
access paths, and all other stream crossings coincide with existing site access paths and existing culverts. Stabilized construction entrances shall be installed where temporary access
paths intersect the existing paved roadways. Stabilized construction entrances will consist of a gravel pad measuring at least 50 feet in length, 12 feet in width, and 6 inches in depth.
The gravel will be placed on filter fabric. The construction entrance is to be inspected weekly and following each rainfall producing 0.5 inch or more of rain.
Indirect impacts may result from the proposed project. Potential indirect impacts include alterations of downstream water quality, temporary alteration of the aesthetic quality of the site,
and increased traffic within the GGCC property during construction. Downstream water quality will be protected by implementation of suitable stormwater Best Management Practices
(BMPs) and a project -specific approved erosion and sedimentation plan. The environmental release channel, which maintains minimum flows from the lake to the downstream reach of
Linville River, will provide protection to Linville River from suspended sediments and turbidity via temporary placement of flo9cculent blocks and coir logs/wattles at the outfall pipe inlet
and within the environmental release channel. The visual character of the GGCC will be temporary altered during construction. The aesthetic impact is part of the reason behind
scheduling construction during the off-season, allowing the number of residents and guests to be affected by the visual impact to be reduced in comparison to the number of people
onsite during GGCC's season. Winter scheduling also minimizes the effects of increased traffic associated with construction as there are fewer vehicles onsite during the winter months.
The proposed construction schedule was developed, giving consideration to restrictions associated with encroachment into trout waters and buffers along trout waters as well as the
dates of the GGCC off-season. The trout waters and buffer time -of -year restriction is herein requested to be adjusted via WRC variance to allow in -water work and land disturbance
within the protected buffer beginning on January 1. Work is proposed to begin in November and be completed by April 30.
During the months of November and December, work is proposed to consist of site preparation and other activities upgradient of the landward limit of the trout buffer, which is 25 feet
wide and abuts the top of bank of the Linville River and Loch Dornie. These activities include installation of stabilized construction entrances and staging areas in high ground,
disassembling of existing wood bridge structures, replacement of existing Bridge G with proposed Bridge #5, and construction of a retaining wall section in high ground by the
clubhouse. Bridge #5 will be assembled on high ground immediately adjacent to the proposed location then lifted into place using a crane. January 1, in -water work and buffer -disturbing
work is proposed to commence. This work shall consist of major grading, dredging, and wall construction, and is expected to occur over a three-month period, ending on or about March
31. Final stabilization measures, bridge construction, and landscaping is one month, occurring from April 1 to April 30.
Construction equipment is anticipated to include large excavators, bulldozers, and dump trucks. Small skid steer loaders are expected to be utilized onsite as well. A crane is proposed
to be used for placing some of the bridge structures. Additionally, jackhammers or similar equipment may be used, if found to be necessary, where bedrock is encountered. A pile driver
may be used to install proposed bridge piers.

E. Impact Justification and Mitigation
1. Avoidance and Minimization
Ia. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Full avoidance of impacts can only be accomplished with a no -build alternative, which leaves bridges in imminent danger of collapse, risks a failure of
sanitary sewer pipelines and associated spillage of raw sewage into the Linville River, and allows the effects of accumulated sediments to remain and
continue to increase. The effects of accumulated sediments include restriction of flow, potential increase in water temperature, excessive growth of
vegetation in shallow lake areas, and possibly increased sedimentation downstream during high flows.
Stormwater Best Management Practices (BMPs) have been included in the project design to ensure that water quality is protected during construction.
BMPs include silt fencing with stone outlets, turbidity curtains downstream of work area and upstream of the lake spillway, and routine inspection and
maintenance of erosion and sediment control measures.
Shoreline stabilization has been designed to be resilient to high flows that are characteristic of the project vicinity. Shoreline and bank stabilization
measures will protect downstream water quality by reducing eroded sediments in the waterway and by providing vegetated shore areas that will
facilitate nutrient and sediment removal from stormwater prior to entering the waterways. Additionally, the island reconstruction and shoreline
stabilization components have been designed to improve flow patterns through the lake and encourage more favorable sediment transport and
sediment deposition patterns, which will help to minimize future maintenance dredging needs and eliminate offsite disposal of dredged materials.
The construction schedule has been set to restrict in -water work during trout spawning period, allowing in -water work and land disturbance within the
25 -foot trout waters buffer to commence no earlier than January 1. The construction schedule requires a variance from the NC Wildlife Resources
Commission (WRC), which is being requested for concurrent review. As a variance was previously authorized by WRC for the project, it is anticipated
that construction will be permitted to begin in January.
Lake and river access points and/or crossings will be provided by eAsting access paths and four temporary construction access paths. The access
plan strikes a balance between minimizing the number of access points and crossings and minimizing excessive vehicular and equipment movements
within the lake and river beds.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
All in-vater work will be performed under dry conditions. Dry work areas will be established using stream diversions to direct river flows into the west or
east channel as needed, draw -down of the lake by 8 feet, gravity -fed piped conveyance of river flows through work areas, and a siphon and pump
system to maintain the lake drawdown. The siphon and pump system will be installed at the downstream end of the lake and will be used to temporarily
dewater the lake, pumping water over the lake spillway as needed to maintain the lake drawdown.
All cast -in-place concrete work shall be performed in dry conditions. All necessary measures will be taken to ensure that surface waters do not contact
wet concrete.
Turbidity curtains will be installed at two locations in the lake. A pair of turbidity curtains will be installed immediately upgradient of the northern edge of
water during lake drawdown to capture suspended sediments at the downgradient edge of the work area associated with the dredging and island
reconstruction. A turbidity curtain will be installed between the edge of water during lake drawdown and the siphon and pump system that will be
placed at the lake spillway.
Silt fencing with stabilized outlets will be installed along the downgradient edge of upland work areas. The silt fence will be inspected regularly and
maintained as needed to ensure efficacy.
Dredging methods were evaluated for the proposed project. Hydraulic dredging of the lake and river bed was considered but determined to not meet
the needs of the project. The time required to remove the necessary volume of material and the cost associated with hydraulic dredging would result
in extending the construction schedule into the GGCC's in -season time and roughly doubling the cost for the dredging.

A Hazen biologist reviewed the habitat requirements for each federally listed species and assessed the availability of suitable habitat within the project
vicinity. Habitat is available within or surrounding the project area for northern long-eared bat. Trees and bridges are proposed to be removed as part
of the project. However, all demolition and site clearing work is proposed to be completed during winter months, which is during the northern long-
eared bat hibernation period. Therefore, no impacts to the species are anticipated to result from the project.

location of this activity on the property.
Blasting is not proposed to occur as part of construction of the proposed project. Jackhammers or
similar equipment may be used, if necessary, where bedrock is encountered. Pile drivers may be used
for placement of proposed bridge piers. The duration of these operations will be determined upon rock
location, depth, and hardness. It is anticipated that jackhammers or similar equipment may be used to
assist grading activities, particularly in the bank stabilization areas. Pile drivers may be used in the
vicinity of proposed bridge #3. Consideration of nearby structures will be given to ensure that
percussive activities do not compromise the structural or visual integrity of existing structures.
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 species
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.

Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be
present in your project area. This information can be used to tailor and schedule your project activities
to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ “Proper
Interpretation and Use of Your Migratory Bird Report” before using or attempting to interpret this
report.
Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your
project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A
taller bar indicates a higher probability of species presence. The survey effort (see below) can be used
to establish a level of confidence in the presence score. One can have higher confidence in the
presence score if the corresponding survey effort is also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in the week
where the species was detected divided by the total number of survey events for that week. For
example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of
them, the probability of presence of the Spotted Towhee in week 12 is 0.25.
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.

no data survey effort breeding season probability of presence
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 ( )
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 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.
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,
Page 8 of 12IPaC: Explore Location
8/18/2019https://ecos.fws.gov/ipac/location/IPPRMEVHGNH2PO5KR5KJBMXTTA/resources
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 AKN Phenology Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in
my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian
Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science
datasets .
Probability of presence data is continuously being updated as new and better information becomes available. To learn
more about how the probability of presence graphs are produced and how to interpret them, go the Probability of
Presence Summary and then click on the "Tell me about these graphs" link.
How do I know if a bird is breeding, wintering, migrating or present year-round in my project area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-
round), you may refer to the following resources:The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you
are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird
on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area,
there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the
bird likely does not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range
anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the
continental USA; and
3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of
the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain
types of development or activities (e.g. offshore energy development or longline fishing).
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid
and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more
information on conservation measures you can implement to help avoid and minimize migratory bird impacts and
requirements for eagles, please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species and groups of bird
species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also
offers data and information about other taxa besides birds that may be helpful to you in your project review.
Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS
Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic
Outer Continental Shelf project webpage.

Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including
migration. Models relying on survey data may not include this information. For additional information on marine bird
tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring.
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle
Act should such impacts occur.
Proper Interpretation and Use of Your Migratory Bird Report
The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern.
To learn more about how your list is generated, and see options for identifying what other birds may be in your project
area, please see the FAQ “What does IPaC use to generate the migratory birds potentially occurring in my specified
location”. Please be aware this report provides the “probability of presence” of birds within the 10 km grid cell(s) that
overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey
effort (indicated by the black vertical bar) and for the existence of the “no data” indicator (a red horizontal bar). A high
survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as
more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of
certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of
concern have the potential to be in your project area, when they might be there, and if they might be breeding (which
means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in
knowing when to implement conservation measures to avoid or minimize potential impacts from your project
activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ “Tell me about
conservation measures I can implement to avoid or minimize impacts to migratory birds” at the bottom of your
migratory bird trust resources page.

Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of
the Clean Water Act, or other State/Federal statutes.
For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers
District.
Please note that the NWI data being shown may be out of date. We are currently working to update our
NWI data set. We recommend you verify these results with a site visit to determine the actual extent of
wetlands on site.
This location overlaps the following wetlands:
Data limitations
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
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
