Charlotte - Mecklenburg Storm Water Services
1.0 INTRODUCTION
The Ashley Farm Pond Project (Project) is located in the Ashley Farms subdivision behind the
residential housing at the intersection of Ashley Farm Drive and Rheinwood Court in Charlotte,
Mecklenburg County, NC (see Appendix A, Figures 1 and 2). The Project proposes to replace
the failing dam structure and to stabilize the eroding channel downstream of the dam.
Charlotte - Mecklenburg Storm Water Services (CMSWS) has retained GAI Consultants (GAI) to
provide Section 404/401 permitting services for this project. On behalf of CMSWS, GAI is
submitting a Pre - Construction Notification (PCN) Application with attachments in accordance
with Nationwide Permit General Condition Number 31, and pursuant to Nationwide Permit
Number 3 and Water Quality Certification #3883. Appendix B contains the complete Joint PCN
Form.

2.0 PROJECT INFORMATION
2.1. Purpose
The purpose of this project is to repair the failing dam and to stabilize the eroding downstream
channel. Proposed pond design measures will meet City of Charlotte design standards and will
incorporate water quality and Flood control improvements.
2.2. Existing Conditions
2.2.1. Vegetation
The current land use for the project area is primarily residential with maintained lawns, and
adjacent wooded areas. Dominant vegetation within the project area consists of green ash
(Fraxinus pennsyivanica), Japanese honeysuckle (Lonicera japonica), black willow (Sa /ix nigra),
fescue (Festuca sp.), box -elder (Ater negundo) and poison ivy (Toxicodendron radicans).
2.2.2. Soil
The Soil Survey of Mecklenburg County (NRCS, 1980) identified two mapped soil types within
the Project vicinity (See Figure 3). Table 1 lists the soil types present within the Project area.

Table 1: • n-Site Soil Types
Map Unit Name Soil Series Name
EnD Enon sandy loam, 8 to 15 percent slopes
EnB Enon sandy loam, 2 to 8 percent slopes
The Enon series soils (EnD and EnB) are well drained and exhibit high permeability.
2.2.3. Aquatic Resources
Existing aquatic resources delineated within the project area includes two wetlands (W1 and
W2), two streams (Stream 1 and Stream 2), and one pond (Pond 1). The streams are
Unnamed tributaries (UTs) to Irvins Creek located within the Santee River basin (CU 03050103).
Irvins Creek is classified as "Class C waters" by the North Carolina Department of Natural
Resources (NCDENR) Division of Water Quality (DWQ). Class C waters are freshwaters identified
for aquatic life propagation and protection. Additionally, Irvins Creek, a tributary to McAlpine
Creek, is not identified as impaired on NCDENR 2012 303(d) list.
3.0 JURISDICTIONAL DETERMINATION
On March 30, 2012, GAI surveyed and preliminarily classified on -site jurisdictional waters of the
U.S. using the U.S. Army Corps of Engineers (USACE) - Routine On -Site Determination Method.
This method is defined in the 1987 Corps of Engineers Wetlands Delineation Manual (USACE,
1987) and the Eastern Mountains and Piedmont Interim Regional Supplement. As a result of
the on -site field investigation two streams, one pond, and two wetlands were identified (Figure
4, Appendix A). The Wetland Determination Data Forms are provided for Wetlands 1 and 2,
designated as WL -1 and WL -2, respectively. Also, field observations, referenced as Data Points
(DP), were recorded on Wetland Determination Data Forms as well. Appendix C contains
complete Wetland Determination Data Forms. Additionally, two stream channels were identified
during the field investigation: Stream 1 and Stream 2. Jurisdictional waters of the U.S. were
classified according to recent NC Department of Environment and Natural Resources Division of
Water Quality (DWQ) (2003) and USACE guidance. Also, DWQ Stream Classification Forms and
USACE Stream Quality Assessment Worksheets for on -site streams are included in Appendix D.
Appendix E contains a complete Approved Jurisdictional Determination Form for the
jurisdictional features identified within the project area.
The USACE issued a Notification of Jurisdictional Determination (USACE Action ID 2012- 00784),
dated July 27, 2012, verifying that the delineated wetlands, stream channels and open water
pond are jurisdictional, and therefore, subject to the requirements of Section 404 of the Clean
Water Act (33 USC § 1344) [see Appendix F].
3.1. Jurisdictional Waters
Stream 1, a UT to Irvins Creek, flows southwest through the Project area for 106 linear feet
before discharging into Pond 1 (See Appendix A, Figure 4). Stream 1 is classified as relatively
permanent waters (RPW) with year -round flow, and exhibits a 3 — 6 foot wide ordinary high
water mark (OHWM). Stream 1 exhibited a well - defined bed and bank, moderate flow and
sinuosity and substrate consisting of silt and at portions of riprap. Stream 1 rated 60 out of a
possible 100 points on the USACE Stream Quality Assessment Form and scored 30 out of 60
possible points on the DWQ Stream Classification Form in Appendix D. Photographs of Stream
1 are in Appendix G as Photograph 1 and Photograph 2.

Ashley Farm Pond Project
Charlotte - Mecklenburg Storm Water Services
Stream 2, a UT to Irvins Creek, originates at the downstream spillway of Ashley Farm Pond,
designated as Pond 1, and flows in a southerly direction for 383 linear feet until its confluence
with Irvins Creek (See Appendix A, Figure 4). Stream 2 is classified as RPW with year -round
flow, and a 6 — 8 foot wide OHWM. Stream 2 also exhibited a well - defined bed and bank
having moderate flow and sinuosity with substrate consisting predominately of silt and rip -rap
at intermittent locations. Stream 2 rated 58 out of a possible 100 points on the USACE Stream
Quality Assessment Form and scored 31.5 out of 60 possible points on the DWQ Stream
Classification Form in Appendix D. Photographs of Stream 2 are in Appendix G as Photographs
3-12.
Ashley Farm Pond (Pond 1) is located between Streams 1 and 2 and is approximately 1.13 acres
in size (See Appendix A, Figure 4). (Please note that the previously submitted JD request
estimated the pond surface area to be 1.23 acres. However, a subsequent physical survey has
established the pond surface area to be 1.13 acres.) The existing dam along the southern side
of'Pond 1 appears to be serviceable. Pond 1 drains in the southeast corner via a drain pipe and
spillway (See Appendix G, Photographs 13 -18). Pond 1 was determined to be jurisdictional due
to the direct hydrologic connection (nexus) to year -round RPWs and jurisdictional wetlands.
Two wetland areas were identified within the project area (WL -1 and WL -2). WL -1 is classified
as a Palustrine Emergent (PEM) wetland, located north of Pond 1 in a floodplain, abutting
Stream 1 (See Appendix G, Photograph 2). WL -1, approximately 0.03 acres in size, is is
situated in a landscaped residence, and had been recently mowed. This wetland exhibited soil
saturation at 6 inches from the surface, sediment deposits, crayfish burrows, geomorphic
position and passed the FAC- Neutral Test. Dominant vegetation identified within WL -1 included
black willow, green ash, common rush (luncus effusus), Japanese honeysuckle, trumpet
creeper (Campsis radicans), fescue and unidentified sedges (Carex sp.). Due to the recent
vegetation maintenance, species identification beyond genus was not feasible for WL -1. Soils
sampled within WL -1 exhibited a loamy gleyed matrix (GLEY 4/10Y) with redox concentrations
in the matrix (10YR 4/6). These sampled soils met the criteria for the loamy gleyed matrix
hydric soil indicator (F2).
WL -2 is classified as a Palustrine Forested (PFO) wetland, located south of Pond 1 in the
floodplain adjacent to Stream 2 (See Appendix G, Photograph 20). WL -2 is approximately
0.073 acres in size. WL -2 exhibited soil saturation, a water table at 4 inches from the surface,
water stained leaves and drainage patterns. Dominant vegetation identified within WL -2
included box - elder, green ash, black willow, jewelweed (Impatiens capensis) and poison ivy.
Soils sampled within WL -2 exhibited a low - chroma matrix (2.5Y 4/2) with redox concentrations
in the matrix (7.5YR 4/6). These sampled soils met the criteria for the depleted matrix hydric
soil indicator (9).
A summary of the jurisdictional features delineated within the project area is provided in Table
2 below.

3.2. Project History
No USACE permits or certifications have previously been requested or obtained for this Project.
3.3. Future Project Plans
This Project is not a phased project and there are presently no future plans for additional
construction.
4.0 PROPOSED IMPACTS INVENTORY
This Project proposes to rehabilitate the Ashley Pond dam and replace the eroding spillway and
makeshift pipe outlet structures with a riser pipe that includes a water quality inlet. Proposed
pond design will result in reduction of the existing pond surface area from 1.13 acre [49,137
square feet (SF)] to 1.08 acre [47,302 SF]. To maintain the approximate permanent pool
surface area, portions of the pond perimeter will be excavated and a retaining wall will be
constructed to maintain the approximate pond extents. In addition, a 0.12 -acre submerged
forebay will be excavated within the footprint of the existing pond to provide enhanced
sediment removal and minimize clogging of the water quality inlet. The proposed water quality
inlet will establish a new normal pool elevation at 623.50 feet versus the original elevation at
625.50 feet. The reduction in water surface elevation is necessary to alleviate flooding
concerns for a submerged stormwater pipe that discharges to the northwest corner of the pond.
Construction of this Project will result in unavoidable impacts to on -site jurisdictional waters of
the U.S. Permanent and temporary impacts to jurisdictional waters are described in the
sections below. These proposed impacts are associated with the maintenance activities
described above and are consistent with the conditions of Nationwide Permit 3 and Water
Quality Certification 3883.
4.1. Wetland Impacts
4.1.1. Wetland 1
Wetland 1 is adjacent to Pond 1 and may experience reduced hydrology as a result of lowering
the pond's normal pool elevation from 625.50 to 623.50 feet. The probable drainage of
Wetland 1 will result in permanent impacts to 0.03 acre. See Sheet 5 of Project Plans in
Appendix H.
• gai consultants
transforming Ideas Into reality&

Ashley Farm Pond Project
Charlotte - Mecklenburg Storm Water Services
4.1.2. Wetland 2
Wetland 2 will incur minor impacts due the new dam having a larger footprint than the existing
dam. The proposed extension of the dam embankment will result in permanent impacts to
0.004 acre to Wetland 2. The minor impact is necessary to achieve a stable slope on the
southern exterior face of the dam. See Sheet 5 of Project Plans in Appendix H.
4.2. Stream Impacts
4.2.1. Stream 1
No permanent or temporary impacts are anticipated for Stream 1.
4.2.2. Stream 2
Temporary impacts proposed to Stream 2 total 159 linear feet due to stabilization of a reach of
stream channel that is currently armored with rip rap. Sheets 5, 8 and 12 of the Project Plans
(Appendix H) illustrate that Stream 2 will be temporarily impacted by the following specific
maintenance activities:
• Removal of 38 linear feet accumulated sediment and placement of rip rap toe within the
stream channel [Station 0 +00 — 0 +38];
• Installation of 33 linear feet of Reno mattress energy dissipater and gabion wall along the
left bank to dissipate energy and prevent erosion of steep embankment, respectively
[Station 0 +38 — 0 +71];
• Placement of 10 linear feet of rip rap within the existing sanitary sewer easement
crossing the spillway [Station 0 +71— 0 +81];
• Installation of 36 linear feet of Reno mattress energy dissipater [Station 0 +81- 1 +17]; and
• Installation of 42 linear -foot culvert outlet under new dam embankment [Station 1 +17 —
1 +59].
4.3. Open Water Pond Impacts
Proposed maintenance activities resulting in temporary impacts within Pond 1 consist of:
temporarily dewatering the pond; reconstructing the dam embankment; installing a spillway
riser and culvert system; excavating and dredging portions of the pond; and installation a
retaining wall along portions of the pond perimeter. In addition, lowering the permanent pool
elevation from 625.50 to 623.50 feet will result in permanent impacts totaling 0.04 acres (1,835
square feet) due to reduction of the pond surface area from 1.13 acres (49,137 square feet) to
1.08 acres (47,302 square feet). The reduction in permanent pool elevation is necessary to get
the water surface below the invert of a stormwater pipe that discharges into the northwest
corner of the pond.

5.0 IMPACT JUSTIFICATION AND MITIGATION
5.1. Avoidance and Minimization
Avoidance and minimization measures consist of:
1. avoiding impacts to Stream 1;
2. re- contouring of the pond perimeter to minimize reduction of pond surface area;
3. re- configuring dam to have minor impacts to Wetland 2; and
4. limiting proposed spillway maintenance to the existing rip rap stabilization area on Stream 2.
During the design process, CMSWS consulted with the agencies during a field meeting on June
12, 2012. A main topic of discussion was the proposed Stream 2 channel work downstream of
the pond. Initial designs considered included extending Stream 2 enhancements further
downstream than the proposed limits of disturbance. However, it was determined during the
6/12/2012 field meeting that (1) the upstream portion of Stream 2 (the reach just downstream
of the pond outlet) is too eroded and steep for enhancement, and (2) the downstream reach of
Stream 2 is relatively stable and wooded. Also, the agencies emphasized the need to protect
large diameter trees within the project area. The proposed stream stabilization design keeps
Stream 2 impacts within the existing armored reach while providing adequate energy dissipation
to minimize potential streambank erosion downstream. To minimize tree impacts and grading,
the area of disturbance will be constricted to space necessary to accomplish the work safely,
trees proposed for protection will be marked, and a retaining wall will be installed along
proposed excavation areas around the pond perimeter.
Further, to minimize adverse impacts to nearby surface waters, the following construction
measures will be applied:
• Appropriate erosion control measures will be implemented. Approximately, 260 linear feet
of silt fence will be installed on the southern end of the pond to prevent erosion. Erosion
control measures will be adjusted as needed during final grading to minimize erosion and
sedimentation;

Avoidance and minimization measures consist of:
1. avoiding impacts to Stream 1;
2. re- contouring of the pond perimeter to minimize reduction of pond surface area;
3. re- configuring dam to have minor impacts to Wetland 2; and
4. limiting proposed spillway maintenance to the existing rip rap stabilization area on Stream 2.
During the design process, CMSWS consulted with the agencies during a field meeting on June

Ashley Farm Pond Project
Charlotte - Mecklenburg Storm Water Services
• The pond will be dewatered 30 days prior to excavation and dredging of interior of pond. A
dewatering sump with float activated pump will be installed to dewater the pond;
• Installation of a temporary bypass ditch to maintain normal downstream flows. The
temporary bypass channel will be excavated upon dewatering with a grade of one percent;
and
• Working platforms will be constructed from crest roads to provide stable work areas to
perform construction activities.
Upon completion of construction of the new dam and spillway, disturbed areas will be seeded
and mulched per Plan specifications. Silt fencing and tree protection measures will remain in
place until disturbed areas are satisfactorily re- vegetated to minimize erosion and
sedimentation. For details on dewatering and erosion control plans see Appendix H, Sheets 9,
11 -12, and D1.
5.2. Compensatory Mitigation
CMSWS has carefully planned the project to avoid and minimize impacts to jurisdictional
features within the project area. As such, permanent impacts have been limited to 0.034 acre
of wetlands and 0.04 acre of pond. CMSWS proposes no additional compensatory mitigation for
impacts to jurisdictional features.
6.0 STORMWATER MANAGEMENT
No land disturbing activity will commence without an approved NCDENR Erosion and Sediment
Control (E&SC) Plan. Upon receiving E&SC Plan approval, the project will be automatically
covered under the state's NPDES Stormwater General Permit NCGO10000 for construction -
related activities. The erosion control measures specified on Sheets 9 — 12 in Appendix H will
be implemented to minimize erosion of soil and sedimentation on- and off -site. The E&SC Plan
and copy of General Permit NCGO10000 will be retained on -site by the contractor. The
Erosion and sediment controls will be inspected after each phase of the project and in
accordance with the E&SC Plan and General Permit NCGO10000 conditions.
7.0 SUPPLEMENTARY INFORMATION
7.1. Endangered Species and Designated Critical Habitat
A letter was forwarded to the North Carolina Natural Heritage Program ( NCNHP) on February
13, 2013 to determine the presence of any federally - listed, candidate endangered, threatened
species or critical habitat located within the proposed Project area. In a response letter dated
February 21, 2013 (Appendix I), the NCNHP indicated that there is a record of an extant
population of Eastern Creekshell (Villosa delumbis) documented from Irvins Creek just
downstream of the project area. V, delumbis is not federally protected but has a state status of
Significantly Rare In regards to the extant population of V, delumbis, this project will provide
water quality benefits for the downstream receiving waters, and therefore will have no adverse
effects on aquatic life.
In addition, historical records of the Tall Larkspur (Delphinium exaltatum; Federal Status -FSC,
State Status - Endangered) and the Shooting -star (Primula meadia, not federally protected, State
gai consultants
transforming Ideas Into reality®

Ashley Farm Pond Project
Charlotte - Mecklenburg Storm Water Services
Status- Threateneo) are found within a two -mile radius of the project area. Regarding the
historical occurrences of D. exa/tatum (last observed in the 1800s) and P, meadia (last observed
in 1970), the lack of recent element occurrences make it highly unlikely that these species will
be impacted by the proposed project.
A copy of this PCN will also be submitted to the U.S. Fish and Wildlife Services to ensure
compliance with Endangered Species Act regulations.
7.2. Essential Fish Habitat
The Magnuson- Stevens Fishery Conservation and Management Act (16 USC 1801 et seq.)
defines Essential Fish Habitat (EFH) as "those waters and substrate necessary to fish for
spawning, breeding, feeding, or growth to maturity" (16 USC 1802(10)). The designation of
EFH is required only for species or species units for which the National Marine Fisheries Service
(NMFS) have developed fisheries management plans. In North Carolina, salt marshes, oyster
reefs, and seagrass beds are designated EFH for red drum and penaeid shrimp, species
managed cooperatively by state and federal authorities. Evaluation of the project location using
NMFS EFH Mapper (http: / /www.habitat.noaa.gov /protection /efh /efhmaWer /) identified no EFH
or Habitat Areas of Particular Concern (HAPC).
7.3. Historic or Prehistoric Cultural Resources
A letter was forwarded to the State Historic Preservation Office (SHPO) on February 13, 2013 to
determine the presence of architectural, historic, or archaeological significant areas that would
be affected by the Project. As of the date of this submittal, a response from SHPO -has not
been received. The occurrence of cultural resources eligible for the National Register of Historic
Places within the Project area has a low probability due to urban development within the last 30
plus years.
7.4. Flood Zone Designation
The North Carolina Floodplain Mapping Program " Floodplain Mapping Information System
(FMIS)" (http: / /www.ncfloodmags.com /) indicate the Project area is not within nor does it
contain Federal Emergency Management Agency (FEMA) regulated floodplains.

3. Project Description
3a. 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 proposed project is located in an existing residential subdivision dominated by maintained lawns, small wooded
areas, and a pond.
3b. List the total estimated acreage of all existing wetlands on the property:
Approximately 0.11 acre
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Approximately 489 linear feet
3d. Explain the purpose of the proposed project:
The purpose of this project is to repair the failing dam and to stabilize the eroding downstream channel. Proposed pond
design measures will meet City of Charlotte design standards and will incorporate water quality and flood control
improvements.
3e. Describe the overall project in detail, including the type of equipment to be used:
Track hoes, bull dozers, dump trucks and other typical excavation equipment will be used for this project. This Project
proposes to rehabilitate the Ashley Pond dam and replace the eroding spillway and makeshift pipe outlet structures with a
riser pipe that includes a water quality inlet. Proposed pond design will result in reduction of the existing pond surface
area from 1.13 acre [49,137 square feet (SF)] to 1.08 acre [47,302 SF]. To maintain the approximate permanent pool
surface area, portions of the pond perimeter will be excavated and a retaining wall will be constructed to maintain the
approximate pond extents. In addition, a 0.12 -acre submerged forebay will be excavated within the footprint of the
existing pond to provide enhanced sediment removal and minimize clogging of the water quality inlet. The proposed
water quality inlet will establish a new normal pool elevation at 623.50 feet versus the original elevation at 625.50 feet.
The reduction in water surface elevation is necessary to alleviate flooding concerns for a submerged stormwater pipe that
discharges to the northwest comer of the pond.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Avoidance and minimization measures consist of: avoiding impacts to Stream 1; re- contouring of the pond perimeter to
minimize reduction of pond surface area; re- configuring dam to have minor impacts to Welland 2; and limiting proposed
spillway maintenance to the existing rip rap stabilization area on Stream 2. During the design process, CMSWS consulted
with the agencies during a field meeting on June 12, 2012 to determine additional Avoidance and Minimization strategies.
See attached supplemental report for details.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Appropriate erosion control measures include: A detailed and staged sediment and erosion contol plan that includes silt fence
and other common S &EC measures; Dewatered the pond 30 days prior to excavation and dredging of interior of pond;
Installation of a temporary bypass ditch to maintain normal downstream flows; Working platforms will be constructed from
crest roads to provide stable work areas to perform construction activities. Upon completion of construction of the new dam
and spillway, disturbed areas will be seeded and mulched per Plan specifications. Silt fencing and tree protection measures
will remain in place until disturbed areas are satisfactorily re- vegetated to minimize erosion and sedimentation. See attached
report and Project Plans for additional details and illustrations.

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more
continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of
100 representing a stream of the highest quality.

(e.g, typically 3 months)
Supporting documentation is presented in Section III.F.

SECTION HI: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section III.A.1 and Section IH.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections IH.A.1 and 2
and Section III.D.1.; otherwise, see Section IH.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanoshave been met.
The agencies will assert jurisdiction over non - navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year -round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year -round
(perennial) flow, skip to Section HI.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for
the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section III.0 below.

Summarize overall biological, chemical and physical functions being performed-
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all Its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to cant' pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:
1. Significant nexus findings for non -RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:

Action Id.: 2012 -00784
Placement of dredged or fill material within waters of the US and/or wetlands without a Department of the Army permit may
constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). If you have any questions regarding this
determination and/or the Corps regulatory program, please contact Amanda Jones at 828 - 271 -7980.
C. Basis For Determination
The site contains wetlands as determined by the 1987 Corps of Engineers Wetland Delineation Manual and the Interim
Regional Supplement to the corps of Engineers Wetlands Delineation Manual: Eastern Mountain and Piedmont Region. These
wetlands are adjacent to stream channels located on the property that exhibit indicators of ordinary high water marks. The
stream channel on the property is an unnamed tributary to Irvins Creek which flows into the Catawba River. An open water
pond is also located on the property and is considered jurisdictional. The Catawba River is located in the Santee watershed and
eventually drains to the Atlantic Ocean. Specifically, the Catawba River joins the Santee - Cooper River in South Carolina
before entering the Atlantic Ocean.
D. Remarks:
E. Attention USDA Program Participants
This delineation/determination has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the
particular site identified in this request. The delineation/determination may not be valid for the wetland conservation
provisions of the Food Security Act of 1985. If you or your tenant are USDA Program participants, or anticipate participation
in USDA programs, you should request a certified wetland determination from the local office of the Natural Resources
Conservation Service, prior to starting work.

Dear Ms. Pyhalampi:
The Natural Heritage Program has no record of rare species or natural communities within the proposed
project area. An extant population of the Eastern Cr+eekshell has been documented from Irvin Creek just
downstream of the referenced project area. In addition, historical records for two other rare species are
found within a two-mile radius of the referenced project area. These records are presented in the table
below:
These records indicate potential for the species occurrence within the project area, if suitable habitat
exists there. Please contact the US Fish and Wildlife Service (Asheville Office) and the Natural Heritage
Program if these or other rare species are found within the project area during your surveys.
The use of Natural Heritage program data should not be substituted for actual field surveys,
particularly if the project area contains suitable habitat for rare species, important natural
communities, or priority natural areas.
Please do not hesitate to contact me ifyou have questions or need further information: 919 - 707 -8687 or
