Attachment A
Proposed Bank Stabilization
3550 Horton Street, Raleigh
The purpose of this project is to stabilize and repair a streambank in two locations. The first location
(Photographs 1 &2) is a manhole which has been exposed due to an eroded streambank. The second
location (Photographs 3 & 4) is a streambank which has failed and risks exposing a nearby manhole and
buried gravity sewer pipe. The project will temporarily impact a total of approximately 600 square feet
of streambank on House Creek near 3550 Horton Street at 35.814213,-78.690962 decimal degrees.
Work will entail creating a dry work area, establishing a stable toe, constructing a stable bank using
rock/geotextile, coir matting and establishing a stable segment of stream bed at the base of the bank.
The site will be accessed by the existing sewer easement from east of the site. 40 LF of the permanent
disturbance will occur inside the maintained easement at the first location (either side of the stream)
and 20 LF of the permanent disturbance will occur at the second location within the maintained
easement. Erosion control measures will be installed prior to work.
Stone will be placed to establish to create a stable work area. Disturbed areas will be reseeded and
mulched when work is complete. It is expected that a rubber tire loader or skid steer loader and a dump
truck will be used to place the boulders, reconstruct the streambank, and stabilize the streambank.
Please see the four attached details: temporary silt fence, temporary construction entrance, bank
stabilization, and seeding details.

FrM '8COOPERATING TECHNICAL PARTNER
This digital Flood Insurance Rate Map (FIRM) was produced through a unique
cooperative partnership between the State of North Carolina and the Federal
Emergency Management Agency (FEMA). The State of North Carolina has
implemented a long term approach to floodplain management to decrease the
costs associated with flooding. This is demonstrated by the State's commitment
to map flood hazard areas at the local level. As a part of this effort, the State of
North Carolina has joined in a Cooperating Technical State agreement with
FEMA to produce and maintain this digital FIRM.

For information and questions about this map, available products associated with this FIRM including
historic versions of this FIRM, how to order products or the National Flood Insurance Program in general,
please call the FEMA Map Information eXchange at 1-877-FEMA-MAP (1-877-336-2627) or visit the FEMA Map
Service Center website at https:Hmsc.fema.gov. An accompanying Flood Insurance Study report, Letter of Map
Revision (LOMR) or Letter of Map Amendment (LOMA) revising portions of this panel, and digital versions of this
FIRM may be available. Visit the North Carolina Floodplain Mapping Program website at https://flood.nc.gov/ncflood,
or contact the FEMA Map Service Center.
Communities annexing land on adjacent FIRM panels must obtain a current copy of the adjacent panel as well as
the current FIRM Index. These may be ordered directly from the Map Service Center at the number listed above.
For community and countywide map dates refer to the Flood Insurance Study report for this jurisdiction.
To determine if flood insurance is available in the community, contact your Insurance agent or call the National
Flood Insurance Program at 1-800-638-6620.
Flood Insurance Study (FIS) means an examination, evaluation, and determination of flood hazards, corresponding
water surface elevations, flood hazard risk zones, and other flood data in a community issued by the North Carolina
Floodplain Mapping Program (NCFMP). The Flood Insurance Study (FIS) is comprised of the following products
used together: the Digital Flood Hazard Database, the Water Surface Elevation Rasters, the digitally derived,
autogenerated Flood Insurance Rate Map and the Flood Insurance Survey Report. A Flood Insurance Survey is a
compilation and presentation of flood risk data for specific watercourses, lakes, and coastal flood hazard areas within
a community. This report contains detailed flood elevation data, data tables and FIRM indices. When a flood study is
completed for the NFIP, the digital information, reports and maps are assembled into an FIS. Information shown on
this FIRM is provided in digital format by the NCFMP. Base map information shown on this FIRM was provided in
digital format by the NCFMP. The source of this information can be determined from the metadata available in the
digital FLOOD database and in the Technical Support Data Notebook (TSDN).
ACCREDITED LEVEE NOTES TO USERS: If an accredited levee note appears on this panel check with your local
community to obtain more information, such as the estimated level of protection provided (which may exceed the
1-percent-annual-chance level) and Emergency Action Plan, on the levee system(s) shown as providing protection
for areas on this panel. To mitigate flood risk in residual risk areas, property owners and residents are encouraged
to consider flood insurance and floodproofing or other protective measures. For more information on flood insurance,
interested parties should visit the FEMA Website at https://www.fema.gov/national-flood-insurance-program.
PROVISIONALLY ACCREDITED LEVEE NOTES TO USERS: If a Provisionally Accredited Levee (PAL) note
appears on this panel, check with your local community to obtain more information, such as the estimated level of
protection provided (which may exceed the 1-percent-annual-chance level) and Emergency Action Plan, on the
levee system(s) shown as providing protection for areas on this panel. To maintain accreditation, the levee owner or
community is required to submit the data and documentation necessary to comply with Section 65.10 of the NFIP
regulations. If the community or owner does not provide the necessary data and documentation or if the data and
documentation provided indicate the levee system does not comply with Section 65.10 requirements, FEMA will
revise the flood hazard and risk information for this area to reflect de -accreditation of the levee system. To mitigate
flood risk in residual risk areas, property owners and residents are encouraged to consider flood insurance and
floodproofing or other protective measures. For more information on flood insurance, interested parties should visit
the FEMA Website at https://www.fema.gov/national-flood-insurance-program.
LIMIT OF MODERATE WAVE ACTION NOTES TO USERS: For some coastal flooding zones the AE Zone
category has been divided by a Limit of Moderate Wave Action (LiMWA). The LiMWA represents the approximate
landward limit of the 1.5-foot breaking wave. The effects of wave hazards between the VE Zone and the LiMWA
(or between the shoreline and the LiMWA for areas where VE Zones are not identified) will be similar to, but less
severe than those in the VE Zone.

TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE ROAD SHALL BE CLEANED THOROUGHLY AT THE END
OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING, AND
TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA (STREET WASHING SHALL BE ALLOWED ONLY AFTER
SEDIMENT IS REMOVED IN THIS MANNER).
13. SITES UTILIZED BY THE CONTRACTOR FOR THE PURPOSE OF STORING EQUIPMENT, EXCESS EXCAVATED
MATERIALS, STRIPPED TOPSOIL, ETC, SHALL BE ENVIRONMENTALLY SUITABLE FOR SUCH PURPOSES AND
SHALL BE APPROVED IN ADVANCE BY THE OWNER. ENVIRONMENTALLY SUITABLE SITES SHALL BE LEVEL,
DEVOID OF MATURE STANDS OF TREES, AND ISOLATED FROM DRAINAGE FACILITIES AND FEATURES, WETLANDS
STREAMS, AND STREAM CORRIDORS. SITES SHALL COMPLY WITH ALL EROSION AND SEDIMENT CONTROL
REQUIREMENTS OF THE TOWN OF CARY.
14. THE CLEANUP AND DISPOSAL OF EXCESS EXCAVATED MATERIALS SHALL BE DONE AS SOON AS PRACTICAL
AND AS THE OWNER MAY DIRECT.
15. CHECK DAMS, SILT FENCE, OR OTHER FILTERING DEVICES SHALL BE MAINTAINED AT AREAS OF STOCKPILED
MATERIALS, EXCAVATED AREAS, CATCH BASINS, AND OTHER STORM WATER INLET STRUCTURES IN
CONSTRUCTION AREAS TO CONTROL SILT RUNOFF.
16. ALL DEWATERING FLOWS SHALL BE KEPT FREE OF SILT, SEDIMENT, DEBRIS, AND OTHER POLLUTANTS
THROUGH APPROPRIATE MEANS (SETTLING BASINS, FILTER, ETC.). FOLLOWING THIS, THE FLOWS SHALL ONLY
BE RELEASED DIRECTLY INTO STORM SEWERS, STREAM CHANNELS, TO OTHER STABILIZED DRAINAGE
COURSES AND NOT INTO EXPOSED SOILS, STEEP SLOPES, OR ANY OTHER SITE WHERE FLOWS COULD
CAUSE FURTHER DAMAGE.
17. CUT AND FILL SLOPES ARE TO BE VERTICALLY TRACKED, HORIZONTALLY SCARIFIED, MATTED, OR OTHERWISE
CONSTRUCTED TO ENHANCE VEGETATIVE GROWTH AND EXPEDITE STABILIZATION. SEEDING SHALL BE
INSTALLED AS PORTIONS OF THESE SLOPES ARE COMPLETED.
18. THE EXISTING EROSION CONTROL FEATURES SUCH AS ROCK CHECK DAMS AND RIP RAP ALONG THE NEW
RECLAIMED WATERLINE ROUTE MUST BE REMOVED AND REPLACED TO FACILITATE INSTALLATION OF THE NEW
RECLAIMED WATERLINE AS SHOWN.
19. IF AT ANY TIME BEFORE THE EXPIRATION OF THE CONTRACT BOND ANY PART OF THE SEEDED AREA IS NOT
IN GOOD CONDITION, THE CONTRACTOR SHALL FERTILIZE AND RESEED AS OFTEN AS NECESSARY TO GET A
GOOD STAND OF GRASS.
20. CONTRACTOR SHALL NOT CROSS ANY DITCH WHEN FLOWING WATER IS PRESENT OR DURING WET WEATHER
UNLESS A PUMP AROUND SYSTEM IS PROVIDED DURING INSTALLATION OF PIPELINE (SEE DETAIL).
PRIOR TO CROSSING A DITCH, CONTRACTOR SHALL VERIFY THAT A TEMPORARY SEDIMENT TRAP OR CHECK
DAM EXISTS DOWNSTREAM OF CROSSING PRIOR TO INSTALLATION OF PIPELINE. IMMEDIATELY AFTER
BACKFILLING OF PIPELINE, DITCH SHALL BE RESTORED TO ORIGINAL GRADE AND STABILIZED. USE EXCELSIOR
MATTING OR RIP RAP AS NECESSARY TO STABILIZE THE DITCH. INSPECT DITCHES IMMEDIATELY AFTER WET
WEATHER EVENT FOR STABILIZATION.
21. WHENEVER CONSTRUCTION CAUSES LAND DISTURBANCE OF ANY KIND WITHIN THE LIMITS OF A DITCH, THE
CONTRACTOR MUST INSTALL EXCELSIOR MATTING OR RIP RAP AS NECESSARY TO STABILIZE THE DITCH.
22. ALL OPEN CUT CROSSINGS OF DITCHES SHALL BE COMPLETED IN ONE WORK DAY.
23. ALL CHECK DAMS SHOULD APPROPRIATELY FILL THE DITCH THEY ARE PLACED IN, SO THAT DRAINAGE IS
FORCED THROUGH THE STRUCTURE. THE ENGINEER WILL NOTIFY THE CONTRACTOR IN WRITING IF ANY
CHECK DAM IS INSUFFICIENTLY SIZED BASED ON THE ENGINEER'S JUDGEMENT. CONTRACTOR WILL REMEDY
THE PROBLEM WITHIN 3 DAYS.

NOTE:
1. Seeding rates are for hulled seed unless otherwise noted.
2. Fertilizer & Limestone - rates to be applied in absense of soils tests. Recommended application rate assumes significantly disturbed site soils with little or no residual value.
3. NR means Species not recommended for this region or application area.
4. Native, warm season grasses require six or more months to germinate under optimum conditions. If they are planted in the summer, then a whole year will have to pass before they germinate.
5. Invasive designation as determined by the N.C. Exotic Pest Pant Council and N.C. Native Plant Society .
6. Sprigging is not recommended for immediate stabilization unless terrain is flat, heavymulch is applied and no other immediate stabilization method is practical.
0
7. Sodding for immediate stabilization - see primary stabilization charts (other information column) and Section 6.12.
00 8. Long term stabilization can only be accomplished with an adequate, immediate, and primary stabilization program. To achieve long term protective cover with the species listed in
this chart, the approved plan, construction sequence and maintenance schedule must include sufficient detail to assure vegetation will be established and maintained. To assure the
long term protective cover will be established, the reviewing and approving governing body may require a performance/maintenance bond.

NOTE:
With the native varieties, the seed mix should be in the range of 15 pounds per acre.
Depending on availability of native seeds adaptable to North Carolina, the percentage
of a particular variety used may be reduced or increased accordingly. Although
diversity is desirable, it is imperative that the primary crop develop and become an
effective protective cover. In addition to the native species mix, additional nurse crop
species must be included to provide immediate stabilization and an adequate ground cover.

IPaC U.S. Fish & Wildlife Service
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 X%46
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. _,P V
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. <X ,I

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.
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 (1)
Vertical black lines superimposed on probability of presence bars indicate the number of
surveys performed for that species in the 10km grid cell(s) your project area overlaps. The
number of surveys is expressed as a range, for example, 33 to 64 surveys.

No Data (—)
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are
based on all years of available data, since data in these areas is currently much more sparse.

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 of r
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.
ti 4.0.% Nwo
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:

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. j

What if I have eagles on my list?v,
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

Coastal Barrier Resources System
Projects within the John H. Chafee Coastal Barrier Resources System (CBRS) may be subject
to the restrictions on Federal expenditures and financial assistance and the consultation
requirements of the Coastal Barrier Resources Act (CBRA) (16 U.S.C. 3501 et seq.). For more
information, please contact the local Ecological Services Field Office or visit the CBRA
Consultations website. The CBRA website provides tools such as a flow chart to help
determine whether consultation is required and a template to facilitate the consultation
process.

The CBRS boundaries used in IPaC are representations of the controlling boundaries, which are depicted
on the official CBRS maps. The boundaries depicted in this layer are not to be considered authoritative for
in/out determinations close to a CBRS boundary (i.e., within the "CBRS Buffer Zone" that appears as a

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
PI.,
For more information please contact the Regulatory Program of the local U.S. Army Corps of
Engineers District.
This location did not intersect any wetlands mapped by NWI.
NOTE: This initial screening does not replace an on -site delineation to determine whether
wetlands occur. Additional information on the NWI data is provided below.
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 local agencies concerning specified agency regulatory
programs and proprietary jurisdictions that may affect such activities.

RE: 3550 Horton St
Dear Jessica Tisdale:
D. Reid Wilson, Secretary
Misty Burhaaan
Deputy Director, Natural Heritage Program
NCNHDE-20232
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/Di rectory_/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, Land and Water 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 rod ney.butler(a)ncdcr.clov or 919-707-8603.

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
