4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past?*
Yes • No Unknown

4f. List the total estimated acreage of all existing wetlands on the property:
0.45 acre
4g. List the total estimated linear feet of all existing streams on the property:
0 linear feet
4h. Explain the purpose of the proposed project:*
The purpose of this project is to provide sewer to a proposed maintenance building at the Benton WTP.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The project is located on the northeast side of the Benton WTP. The project proposes to construct a new maintenance building and then connect that building to the nearest existing sewer
located in the floodplain of Mahlers Creek. The proposed 6" sewer connection runs 492 linear feet southeast to the existing City of Raleigh manhole.
The proposed project would have one wetland crossing. Impact details can be seen on Plan Sheet C-1.3. The wetland crossing would have a total of 0.067 acre of permanent impact, with
no loss of Waters of the US. All permanent wetland impacts are associated with the clearing and conversion of forested wetlands into herbaceous wetlands within the proposed
maintenance/access corridor. All impact areas will be returned to existing grade after installation of the waterline with the exception of manholes per the plans attached.
Sediment and erosion control measures would be implemented according to NC requirements, and approved by NCDEMLR prior to implementation. Jurisdictional areas adjacent to
construction areas would be clearly marked with protection fencing or other similar methods to avoid inadvertent encroachment. Copies of permits and impact areas would be provided to
the prime contractor and all subcontractors working in or near jurisdictional areas. Land clearing would take place along with the installation of erosion control devices. Construction would
be accomplished using typical equipment including excavators and backhoes for trench construction. Additional standard equipment may be used as required.
5. Jurisdictional Determinations

E. Impact Justification and Mitigation

1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The proposed sewer is designed to cross jurisdictional areas at a perpendicular angle to minimize impacts. Sewer design and location avoids several
other wetlands to the north of the proposed project.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Best management practices and sedimentation and erosion control methods will be used throughout construction. No equipment or maintenance
activities will occur adjacent to jurisdictional areas, with the exception of addressing emergency equipment failure. All temporary impacts to jurisdictional
wetlands during construction will be returned to their original configuration and seeded in a timely manner for stabilization.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
Yes • No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Total permanent impact to wetlands is less than 0.10 acre and does not typically require mitigation under a NWP 58. The permanent impact will result in conversion rather than loss of
aquatic resources.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan
la. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
• Yes No
What type of SCM are you providing?
Level Spreader
Vegetated Conveyance (lower SHWT)
Wetland Swale (higher SHWT)
Other SCM that removes minimum 30% nitrogen
Proposed project will not create concentrated stormwater flow through the buffer
2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?*
Yes • No
2b. Does this project meet the requirements for low density projects as defined in 15A NCAC 02H .1003(2)?
• Yes No
Comments:
All stormwater flows generated by the maintenance building and associated impervious surfaces will be collected and routed to existing stormwater facilities associated with the Benton
WTP (Plan Sheet C-1.1). The additional diversion ditch is not anticipated to create concentrated flows through riparian buffer areas, which are located more than 100 feet from the
structure. The sewer line infrastructure will add minimal additional impervious surface. No significant generation of stormwater is anticipated.
G. Supplementary Information
1. Environmental Documentation
la. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land?*
• Yes No
1 b. If you answered "yes" to the above, does the project require preparation of an environmental document pursuant to the requirements of the National or State (North Carolina)
Environmental Policy Act (NEPAISEPA)?*
Yes • No
Comments: *
Local government funds will be used to construct the project, which does not meet the criteria required for the preparation of an environmental document
under SEPA.
2. Violations (DWR Requirement)
2a. Is the site in violation of DWR Water Quality Certification Rules (15A NCAC 2H .0500), Isolated Wetland Rules (15A NCAC 2H .1300), or DWR Surface Water or Wetland Standards or
Riparian Buffer Rules (15A NCAC 2B .0200)?*
Yes • No
3. Cumulative Impacts (DWR Requirement)
3a. Will this project result in additional development, which could impact nearby downstream water quality?*
Yes • No

3b. If you answered "no," provide a short narrative description.

GROUND STABILIZATION AND MATERIALS HANDLING PRACTICES FOR COMPLIANCE WITH
THE NCGO1 CONSTRUCTION GENERAL PERMIT
Implementing the details and specifications on this plan sheet will result in the construction
activity being considered compliant with the Ground Stabilization and Materials Handling
sections of the NCGO1 Construction General Permit (Sections E and F, respectively). The
permittee shall comply with the Erosion and Sediment Control plan approved by the
delegated authority having jurisdiction. All details and specifications shown on this sheet
may not apply depending on site conditions and the delegated authority having jurisdiction.

there is zero slope
Note: After the permanent cessation of construction activities, any areas with temporary
ground stabilization shall be converted to permanent ground stabilization as soon as
practicable but in no case longer than 90 calendar days after the last land disturbing
activity. Temporary ground stabilization shall be maintained in a manner to render the
surface stable against accelerated erosion until permanent ground stabilization is achieved.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the
techniques in the table below:
Temporary Stabilization
Permanent Stabilization
• Temporary grass seed covered with straw or
other mulches and tackifiers
• Hydroseeding
• Rolled erosion control products with or
without temporary grass seed
• Appropriately applied straw or other mulch
• Plastic sheeting
• Permanent grass seed covered with straw or
other mulches and tackifiers
• Geotextile fabrics such as permanent soil
reinforcement matting
• Hydroseeding
• Shrubs or other permanent plantings covered
with mulch
• Uniform and evenly distributed ground cover
sufficient to restrain erosion
• Structural methods such as concrete, asphalt or
retaining walls
• Rolled erosion control products with grass seed
POLYACRYLAMIDES (PAMS) AND FLOCCULANTS
1. Select flocculants that are appropriate for the soils being exposed during
construction, selecting from the NC DWR List of Approved PAMS/Flocculants.
2. Apply flocculants at or before the inlets to Erosion and Sediment Control Measures.
3. Apply flocculants at the concentrations specified in the NC DWR List of Approved
PAMS/Flocculants and in accordance with the manufacturer's instructions.
4. Provide ponding area for containment of treated Stormwater before discharging
offsite.
5. Store flocculants in leak -proof containers that are kept under storm -resistant cover
or surrounded by secondary containment structures.
EQUIPMENT AND VEHICLE MAINTENANCE
1. Maintain vehicles and equipment to prevent discharge of fluids.
2. Provide drip pans under any stored equipment.
3. Identify leaks and repair as soon as feasible, or remove leaking equipment from the
project.
4. Collect all spent fluids, store in separate containers and properly dispose as
hazardous waste (recycle when possible).
5. Remove leaking vehicles and construction equipment from service until the problem
has been corrected.
6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products
to a recycling or disposal center that handles these materials.
LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE
1. Never bury or burn waste. Place litter and debris in approved waste containers.
2. Provide a sufficient number and size of waste containers (e.g dumpster, trash
receptacle) on site to contain construction and domestic wastes.
3. Locate waste containers at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
4. Locate waste containers on areas that do not receive substantial amounts of runoff
from upland areas and does not drain directly to a storm drain, stream or wetland.
5. Cover waste containers at the end of each workday and before storm events or
provide secondary containment. Repair or replace damaged waste containers.
6. Anchor all lightweight items in waste containers during times of high winds.
7. Empty waste containers as needed to prevent overflow. Clean up immediately if
containers overflow.
8. Dispose waste off -site at an approved disposal facility.
9. On business days, clean up and dispose of waste in designated waste containers.
PAINT AND OTHER LIQUID WASTE

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
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
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. i
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 species1 and their critical habitats are managed by the Ecological Services Program of
the U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic
and Atmospheric Administration (NOAA Fisheries).
Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown
on this list. Please contact NOAA Fisheries for species under their jurisdiction.
1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also
shows species that are candidates, or proposed, for listing. See the listing status page for
more information. IPaC only shows species that are regulated by USFWS (see FAQ).

The birds listed below are birds of particular concern either because they occur on the
USFWS Birds of Conservation Concern (BCC) list or warrant special attention in your
project location. To learn more about the levels of concern for birds on your list and how
this list is generated, see the FAQ below. This is not a list of every bird you may find in this
location, nor a guarantee that every bird on this list will be found in your project area. To see
exact locations of where birders and the general public have sighted birds in and around
your project area, visit the E-bird data mapping tool (Tip: enter your location, desired date
range and a species on your list). For projects that occur off the Atlantic Coast, additional
maps and models detailing the relative occurrence and abundance of bird species on your

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.ak
'"
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 ( )
https://ipac.ecosphere.fws.gov/location/ZGZRCN2A4ZHCRAPH5VCJYA3SKY/resources 8/16

6/16/22, 11:16 AM IPaC: Explore Location resources
Vertical black lines superimposed on probability of presence bars indicate the number of
surveys performed for that species in the 10km grid cell(s) your project area overlaps. The
number of surveys is expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data ( )
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are
based on all years of available data, since data in these areas is currently much more sparse.

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 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.
https://ipac.ecosphere.fws.gov/location/ZGZRCN2A4ZHCRAPH5VCJYA3SKY/resources 11/16

6/16/22, 11:16 AM IPaC: Explore Location resources
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge
Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science
datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid
cell(s) which your project intersects, and that have been identified as warranting special attention because
they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a
particular vulnerability to offshore activities or development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area.
It is not representative of all birds that may occur in your project area. To get a list of all birds potentially
present in your project area, please visit the 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
�c A
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.

Data limitations
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
hatched area on either side of the boundary). For projects that are very close to a CBRS boundary but do
not clearly intersect a unit, you may contact the Service for an official determination by following the
instructions here: https://www.fws.gov/service/coastal-barrier-resources-system-property-documentation
Data exclusions
CBRS units extend seaward out to either the 20- or 30-foot bathymetric contour (depending on the location
of the unit). The true seaward extent of the units is not shown in the CBRS data, therefore projects in the
offshore areas of units (e.g., dredging, breakwaters, offshore wind energy or oil and gas projects) may be
subject to CBRA even if they do not intersect the CBRS data. For additional information, please contact

Wetlands in the National Wetlands Inventory
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.
WETLAND INFORMATION IS NOT AVAILABLE AT THIS TIME
This can happen when the National Wetlands Inventory (NWI) map service is unavailable, or
for very large projects that intersect many wetland areas. Try again, or visit the NWI map to
view wetlands at this location.
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.

Dear Brian Smith:
D_ Reid Wilson, Secretary
Misty Buchanan
Deputy Director, Natural Heritage Program
NCNHDE-18313
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 [e-mail] 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
