MEMORANDUM
TO: Kyle Barnes
FROM: Central Office Triage (via Amanda Mueller)
Michael F. Easley, Governor
William G. Ross Jr., Secretary
North Carolina Department of Environment and Natural Resources
Alan W. Klimek, P.E. Director
Division of Water Quality
DATE: May 4, 2006
RE: Farmville Golf and Country Club Stream and Wetland Restoration (DWQ #v2 04-1923)
The central office has reviewed this application for a 401 certification for a NWP 27. Several aspects of
the application require a site visit for the verification of the information provided. Upon visiting the site
please observe and make determinations on the following features.
Stream Enhancement and Restoration:
1. If any or all of this project is approved will they be able to ensure that the golf course has no
negative impacts on the restored or enhanced areas (sediment or nutrient loading, pedestrian
impacts, etc).
2. Why is the bridge and cart path at the top of the reach being relocated? If it is because of the
bank erosion immediately downstream, will relocation of the bridge and path merely cause
the same problem farther downstream?
3. Does Little Contentnea creek need enhancement and will bank stabilization and the addition
of in-stream structures be sufficient to allow enhancement credits.
4. Where on Little Contentnea creek is the 300' of restoration? If it is the removal of the weir
and the upstream sediments, is this sufficient for restoration or would it constitute
enhancement?
5. The application states that the upstream portion of the UT to Little Contentnea creek was
recently restored. What impact if any will this have on the proposed restoration reach.
6. Is restoration necessary on the UT to Little Contentnea creek? If it is necessary, is the
number and tightness of meanders proposed on the restoration plans appropriate?
7. The aerial photo shows a portion of the proposed restoration reach for the UT to Little
Contentnea creek crossing a fairway. Is a woody vegetated buffer going to be able to be
established along this section of the creek?
Wetland Restoration:
1. Please verify that the areas proposed for wetland restoration are not already wetlands. Based
on the aerial photograph, at least portions of the area proposed for wetland restoration appear
to have wet areas or distinct vegetation characteristics.
2. They have proposed grading the areas for wetland restoration. How will this impact the
current trees on site?

If the site is viable for stream and wetland enhancement and restoration some conditions that need to be
included in the certification are:
1. Monitoring must be conducted on the enhanced and restored areas for the stream. Therefore,
more cross sections will be necessary in Little Contentnea creek to assess the enhancement
areas as well.
2. The monitoring plan should include the number, location, and data to be collected in the
vegetation plots for the stream enhancement and restoration areas.
3. On page 19 and 20 of the restoration plan the Wetland monitoring should state, "Monitoring
efforts will be performed for five years or until success criteria are satisfied, whichever is
longer."
4. All restored wetland areas need to contain at least one monitoring well.
5. Hydrologic success should be inundation or saturation within 12 inches of the ground surface
for a number of consecutive days to equal or exceed 12.5%0 of the growing season. The
references gauges within the Riverine wetlands should be included for comparison data in the
event that the success criteria are not met, but they should not be included as part of the
success criteria.
6. Vegetation surveys should be conducted during the growing season.
7. The location of all monitoring wells and vegetation surveys need to be shown to ensure
representative monitoring locations.

N7111. :Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http:.Iili2o.enr.state.ne.us/nc,,vetlands/strm2ide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
The restoration plan is attached. The plan indicates the conservation easement
acquired by the state, plan views, cross section view and proposed method of
enhancement and restoration.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at hgp:/ih2o.enr.state.nc.us/wr2/index.htm. If

FARMVILLE GOLF & COUNTRY CLUB MITIGATIONSITE
General Site Conditions
The hydrological features on the Farmville Golf & Country Club Mitigation Site include the
project reach of Little Contentnea Creek, two UTs, a riverine wetland, and various small
drainages. The wetland area appears to be the historical location of Little Contentnea Creek, prior
to channelization. The drainage area for the main stem of Little Contentnea Creek is
approximately 55.2 square miles and 100 acres for the UT.
There are two terrestrial communities (defined by plant composition) located within the project
study area. Community boundaries within the study area are generally well defined without a
significant transition zone between them. The observed communities are the Coastal Plain Small
Stream Swamp (Blackwater Subtype), and the Disturbed Mesic Mixed Hardwood (Coastal Plain
Subtype). Two soil series are mapped within the project study area: Bib (Bb) and Tuckerman
(Tu) (USDA 1974). Both soil series are classified as hydric.
There are four federally protected species listed for Pitt County, North Carolina: bald eagle, red-
cockaded woodpecker, West Indian manatee, and the Tar spinymussel. As of February 2004, the
Natural Heritage Programs database of threatened and endangered species (NHP) reported no
individuals or populations of any federally protected species within 1.0 mile of the Site.

L 0 GOALS AND OBJECTIVES
The goals of the Farmville Golf & Country Club Mitigation Site are 1) to enhance approximately
1,330 feet and restore 300 feet of Little Contentnea Creek, 2) to restore approximately 680 feet
of an unnamed tributary (UT) to Little Contentnea Creek to a stable stream system with abundant
aquatic and terrestrial habitat, 3) to restore approximately 1.2 acres of a filled riverine wetland to
its original wetland elevation and revegetate with native woody species, and 4) to preserve
approximately 1.3 acres of an existing wetland.
2.0 LOCATIONINFORMATION
The Farmville Golf & Country Club is an active golf course located off U.S. Highway 258 in
Farmville, North Carolina (Figure 1). The proposed restoration area includes two streams: Little
Contentnea Creek and one UT to Little Contentnea Creek; and one riverine wetland located
within the Little Contentnea Creek floodplain. Little Contentnea Creek's main channel reach
totals approximately 1,630 linear feet and the tributary reach totals approximately 680 linear feet.
The proposed wetland restoration area encompasses approximately 1.2 acres. The drainage area
for the main stem of Little Contentnea Creek is approximately 55.2 square miles and 100 acres
for the UT. The following information is in reference to the proposed restoration reach:

4.0 EXISTING CONDITIONS
4.1 Hydrological Features
The hydrological features on the Farmville Golf & Country Club Mitigation Site include the
project reach of Little Contentnea Creek, two UTs, a riverine wetland, and various small
drainages (Figure 2). The wetland area appears to be the historical location of Little Contentnea
Creek, prior to channelization.
4 4.2 Soils
Two soil series are mapped within the project study area: Bib (Bb) and Tuckerman (Tu) (USDA
1974) (Figure 3). Both soil series are classified as hydric.
4.3 Terrestrial Communities
There are two terrestrial communities (defined by plant composition) located within the project
study area. Community boundaries within the study area are generally well defined without a
significant transition zone between them. The observed communities are mapped in Figure 3
and described below.
4.3.1 Coastal Plain Small Stream Swamp (Blackwater Subtype)
The Coastal Plain Small Stream Swamp (Blackwater Subtype) is found in the floodplains of
small blackwater streams in which separate fluvial features and associated vegetation are too
small or poorly developed to distinguish (Schafale and Weakley 1990). This community is
typically found on various alluvial or organic soils and may resemble brownwater communities
in areas where agriculture has increased stream sediment loading.
The Coastal Plain Small Stream Swamp (Blackwater Subtype) observed within the project study
area is located within the Little Contentnea Creek floodplain. It appears to be the relict channel
of Little Contentnea Creek prior to channelization of the existing reach. Dominant canopy
species observed in this community included red maple (Acer rubrum), swamp chestnut oak
(Quercus michauxii), American elm (Ulmus americana), bald cypress (Taxodium distichum),
swamp cottonwood (Populus heterophylla), and cherrybark oak (Quercus pagodifolia). The
observed shrub/sapling species included ironwood (Carpinus caroliniana), red maple, and
Chinese privet (Ligustrum sinense). Observed herbaceous and woody vine species included
common greenbrier (Smilax rotundifolia), grape (Vitis sp.), Japanese honeysuckle (Lonicera
japonica), poison ivy (Toxicodendron radicans), and rattan vine (Berchermia scandens).

4.3.2 Disturbed Mesic Mixed Hardwood Forest (Coastal Plain Subtype)
The maintained/disturbed community represents the most extensive plant community in the
project study area and is located within the golf course greens-fairways, and wood edges. These
areas are regularly maintained and include herbs, saplings, and other plant species typically
found in early successional communities. The canopy stratum includes scattered cherry bark
oak, sweetgum, bald cypress, red maple, and American elm. The observed herbaceous species
includes fescues (Festuca spp.), violets (Viola spp.), cress (Cardamine sp.), water pennywort
(Hydrocotyle americana), sourgrass (Oxalis sp.), blackberry (Rubus sp.), and clover (Trifolium
sp.).
4.4 Federally Protected Species
There are four federally protected species listed for Pitt County, North Carolina. As of February
2004, the Natural Heritage Programs database of threatened and endangered species (NHP)
reported no individuals or populations of any federally protected species within 1.0 mile of the
Site. Table 1 includes all federally protected species listed for Pitt County. A discussion of the
findings pertaining to suitable habitat and the presence or likely presence of individual organisms
or populations is provided below.
Table 1. Federally Protected Species for Pitt County.
Scientific Name Common Name Status
Haliaeetus leucoce halus Bald eagle Threatened*
Picoides borealis Red-cockaded woodpecker Endangered
Trichechus manatus West Indian manatee Endangered
Elli do steinstansana Tars in mussel Endangered
*Proposed for delisting.
Bald Eagle Biological Conclusion: No Effect
The bald eagle (Haliaeetus leucocephalus) is listed as threatened on the USFWS list of
threatened or endangered species (March 11, 1967). Adult bald eagles can be identified by their
large white head and short white tail. The body plumage is dark-brown to chocolate-brown in
color. In flight, bald eagles can be identified by their flat wing soar.
Eagle nests are found in close proximity to water (within a half mile) with a clear flight path to
the water, in the largest living tree in that area, and having an open view of the surrounding land.
Human disturbance can cause an eagle to abandon otherwise suitable habitat. The breeding
season for the bald eagle begins in December or January. Fish are the major food source for bald
eagles. Other sources include coots, herons, and wounded ducks. Food may be live or carrion.

FARMVILLE GOLF & COUNTRY CLUB MITIGATIONSITE RESTORATIONPLAN
Habitat in the form of large living trees with a clear flight path (within a half mile) to a large
stream or lake is not found within the project study area. Additionally, no eagles or nests were
observed at the time of the surveys. Consequently, construction of the Farmville Golf & Country
Club Mitigation Site will have "No Effect" on the bald eagle or its preferred habitat.
Red cockaded woodpecker Biological Conclusion: No Effect
The adult red-cockaded woodpecker (Picoides borealis) has plumage that is entirely black and
white except for small red streaks on the sides of the nape in the male. Distinctive color patterns
for the red-cockaded woodpecker include a large white cheek patch surrounded by the black cap,
nape, and throat; black and white horizontal stripes along the back; and a white breast with
streaked flanks.
{
Habitat for the red-cockaded woodpecker consists of old-growth open stands of southern pines,
which are utilized for foraging and nesting grounds. The red-cockaded woodpecker shows a
particular affinity for stands of longleaf pine (Pinus palustris). Inhabited stands typically contain
more than 50 percent pine, lack a thick understory, and are contiguous with other suitable stands.
The red-cockaded woodpecker nests exclusively in living pine trees that are greater than 60 years
in age and are contiguous with pine stands that are at least 30 years in age.
Habitat in the form of old-growth open stands of pines lacking a thick understory and contiguous
with a pine stand at least 30 years in age is not present within the project study area. Therefore,
the project study area did not meet the habitat requirements for the red-cockaded woodpecker.
Consequently, construction of the Farmville Golf & Country Club Mitigation Site will have "No
Effect" on the red-cockaded woodpecker or its preferred habitat.
West Indian Manatee Biological Conclusion: No Effect
The West Indian Manatee is listed as Endangered on the USFWS list of threatened or
endangered species. They are large gray or brown aquatic mammals with adults averaging about
10 feet long and weighing 1,000 pounds. Manatees have no hindlimbs, and their forelimbs are
modified as flippers. Their tails are flattened horizontally and rounded, with sparse hair covering
their bodies and stiff whiskers covering their muzzles. The sexes of manatees are distinguished
by the position of the genital openings and presence or absence of mammary glands. They will
spend about 5 hours a day feeding, and may consume aquatic vegetation equaling 4 to 9 percent
of their body weight. Although primarily herbivorous, they will occasionally feed on fish.
The habitat for manatees includes both salt and fresh water of sufficient depth (4.9 feet to usually
less than 19.6 feet) throughout their range. They may be encountered in canals, rivers, estuarine

habitats, saltwater bays, and on occasion have been observed as much as 3.7 miles off the Florida
Gulf coast. Between October and April, West Indian manatees concentrate in areas of warmer
water. When water temperatures drop below about 21 to 22 degrees Centigrade, they migrate to
south Florida or form large aggregations in natural springs and industrial outfalls. Severe cold
fronts have been known to kill manatees when the animals did not have access to warm water
refuges. During warmer months they appear to choose areas based on an adequate food supply,
water depth, and proximity to fresh water. Manatees may not need fresh water but they are
frequently observed drinking fresh water from hoses, sewage outfalls, and culverts.
Habitat in the form of salt and/or fresh water canals, rivers, estuarine habitats, or saltwater bays
with depths ranging from 4.9 to 19.6 feet were not observed within the project study area.
Consequently, construction of the Farmville Golf & Country Club Mitigation Site will have "No
Effect" on the West Indian Manatee or its preferred habitat.
Tar spinymussel Biological Conclusion: No Effect
The Tar spinymussel (Elliptio steinstansana) is listed as endangered on the USFWS's list of
threatened or endangered species (July 29, 1985). This mussel grows to an average length of 2.4
inches and has short spines arranged in a radial row anterior to the posterior ridge on one valve
and symmetrical to the other valve. The shell is generally smooth in texture with as many as 12
spines that project perpendicularly from the surface and curve slightly ventrally. However, adult
specimens tend to lose their spines as they mature. The Tar spinymussel is distinguished by its
shiny periostricum, parallel pseudocardinal teeth, and the linear ridges on the inside surface of
the shell.
Previously this mussel was believed to be endemic to the Tar River system, currently occurring
in relatively short stretches of the Tar River and three creeks (Shocco, Sandy/Swift, and Little
Fishing) in the Tar drainage. Historically the Tar spinymussel was collected in the Tar River
from near Louisburg in Franklin County to Falkland in Pitt County (approximately 78 river
miles). In 1983 the Tar spinymussel was located in only a 12-mile stretch of the Tar River in
Edgecombe County. Recently (1998) the Tar spinymussel was found in the Little River of the
Neuse River Basin. The preferred habitat of the Tar spinymussel in Swift Creek was described
as relatively fast flowing, well oxygenated, circumneutral pH water in sites prone to significant
swings in water velocity, with a substrate comprised of relatively silt-free loose gravel and/or
coarse sand.
Habitat within the project reach is generally unsuitable for the Tar spinymussel. However, a
mussel survey was conducted on June 14, 2005 but no individuals of Tar spinymussel were

found (see Appendix A). Consequently, mitigation activities within the Farmville Golf &
Country Club Mitigation Site will have "No Effect" on the Tar spinymussel or its preferred
habitat.
4.5 Existing Condition Stream Geometry and Substrate Data
The project reach of Little Contentnea Creek on the Farmville Golf & Country Club Mitigation
Site is classified as an "B5" channel with very low sinuosity. The profile of the channel is
currently devoid of any significant pool habitat other than one large scour hole immediately
downstream of the bridge crossing at the upstream end. The bridge crossing is also creating
extensive bank erosion downstream. The project reach is lacking in woody debris, which is
typically a major contributor to in-stream habitat in coastal plain streams. At the end of the
project reach a low weir is creating some backwater and causing sediment to deposit upstream.
The geometry of the existing channel is as follows:
Table 2. Existing Condition Data for Classification
Width/De th Ratio 10
Entrenchment Ratio 12.5
Cross-sectional Area 160 square feet
Sinuosity 1.1
The substrate of the channel is sand with some organic/mucky material. There is just enough
clay or silt present in the bank material to allow for excavation without collapsing banks. This
will allow for installation of in-stream structures.
The UT to Little Contentnea Creek is classified as an "B5" channel, however, the project reach
has been severely altered by dredging and erosion. Excavation and clearing operations have
resulted in a channel dimension that is excessively enlarged and has only limited in-stream
habitat. The channel pattern has been straightened and the profile lacks significant pools. There
are several locations where erosion has resulted in bank failure.
The existing condition stream geometry and substrate data for the main stem of Little Contentnea
Creek and the UT to Little Contentnea Creek is located in Appendix B of this report.

o existing conditions
o proposed conditions
o reference conditions
Figure 4 provides a scaled plan view of the project study area showing existing channel location,
proposed channel location, proposed in-stream structure locations, and the adjacent buffer areas.
6.1 Project Narrative and Recommendations
It is the recommendation of HSMM that the reach of Little Contentnea Creek at the Farmville
Golf & Country Club Mitigation Site be enhanced in its present locations with the replacement
of the upstream bridge crossing, installation of in-stream structures for aquatic habitat, riparian
plantings, and removal of the low weir and portions of the spoil berm. The constraints on-site
include the FEMA restrictions for a No-Rise certification, a significant adjacent wetland, mature
woody vegetation, and channel crossings at both the up and down stream ends of the project.
This reach of Little Contentnea Creek was straightened and channelized over seventy (70) years
ago and has since remained in its current location.
The adjacent wetland area may have previously been the location of multiple channels which
carried the water through this reach. Consideration was given to possible diversion of the
existing channel back into these relic channel features. However, the cross sectional geometry of
the relic is significantly smaller than the current bankfull geometry of Little Contentnea Creek.
This is in part due to deposition in the relic section but also attributable to the likelihood that the
historic geometry consisted of multiple channels of which the relic is only a portion. As a
consequence, re-diversion of flow back into this reach would require significant over-excavation
of the section. Currently that area is a well vegetated, thriving wetland which provides excellent
habitat and flood storage for the project reach during high flow conditions.
The banks of the existing channel are generally stable, except immediately downstream of the
upstream crossing. We recommend replacing this crossing with a prefabricated single span type
bridge which would significantly increase the opening area and reduce the back-eddy affect that
is resulting in these bank failures. The portions of the channel banks that are adjacent to the
existing bridge will need to be reconstructed and stabilized. The majority of the stream banks
along the project reach can remain in their current state, with the exception of removal of select

o Maintenance and Contingency Plans
o References
9.1 Schedule and Methodology
The proposed monitoring schedule and methodology presented are per the current guidelines for
monitoring mitigation projects set forth by the regulatory agencies, including the NC DENR
Division of Water Quality and the US Army Corps of Engineers, Wilmington District. This
information was obtained from the Stream Mitigation Guidelines, April 2003.
Upon completion of construction of the mitigation project, an as-built survey will be completed.
This survey will determine the permanent cross-sections, photo points, vegetation plots, and
benchmarks necessary for future monitoring efforts. The surveying methodology will follow the
USDA Forest Service Manual "Stream Channel Reference Sites" (Harrelson, et al, 1994). This
information will be used to document the dimension, pattern, and profile of the restored channel.
The permanent cross-sections will be installed every twenty (20) times the bankfull width, with
50% located in pools and 50% located in riffles. It is also recommended to try and identify
locations that may have problems in the future, and locate cross-sections there if possible. The
Farmville Golf and Country Club Site will have a total of two cross sections located within Little
Contentnea Creek and six cross sections located within the UT to Little Contentnea Creek (3 in
pools and 3 in riffles). The photo documentation should also target possible problem areas, and
focus mainly on in-stream structures and be located at permanent cross-sections. Photos should
be taken twice a year to show the site with and without vegetation that has leafed out.
Additionally, the as-built survey should result in data that can be exhibited as a plan view
diagram of the project site. The length of the longitudinal profile for the project should be 3,000
linear feet or 30 % of the project length, whichever is longer. If the project is shorter than this,
the profile should be for the entire length of the site. Pebble counts should be conducted at six
permanent cross-sections or all if fewer are present. The duration of monitoring efforts is a
minimum of five (5) years and should include at least two bankfull events. If more time is
needed to achieve the flow requirements, it will be decided on a case-by-case basis whether or
not to extend the monitoring period.
9.2 Success Criteria
The following information will be used to evaluate the success or failure of a project. This
information is taken directly from the current US Army Corps of Engineers, Wilmington District
Stream Mitigation Guidelines, as found on:

Photo documentation shall be utilized to assess channel aggradation or degradation, bank
erosion, success of riparian vegetation, effectiveness of erosion control measures, and the
presence or absence of developing instream bars. Ecological function will be assessed by
determining the health and survival of vegetation and by determining if the restoration reach
mimics reference conditions. Channel stability will be evaluated on the basis of channel
alterations relative to the as-built dimensions and whether any alterations represent a movement
in the direction of instability (e.g. increased width to depth ratio or a decreased width to depth
ratio with decreased entrenchment ratio).
Annual monitoring forms will require as-built plans and current data. Monitoring reports shall
contain a discussion of any deviations from as-built and an evaluation of the significance of these
deviations and whether they are indicative of a stabilizing or destabilizing situation.

FARMVILLE GOLF & COUNTRY CLUB MITIGATION SITE RESTORATIONPLAN
10.0 WETLAND RESTORATIONPLAN
Site performance and success criteria for the Farmville Golf & Country Club Mitigation Site will
be based on the successful establishment of wetland hydrology and vegetation. All wetland
restoration monitoring efforts will be performed for a minimum of five years or until the success
criteria are satisfied.
10.1 Wetland Restoration
Wetland restoration efforts for the Farmville Golf & Country Club Mitigation Site will consist of
approximately 1.2 acres of riverine wetlands (see Figure 4) located in select areas adjacent to the
existing Coastal Plain Small Stream Swamp (Blackwater Subtype) wetland. The proposed
restoration efforts include removing invasive exotic plant species (Chinese privet), grading the
existing elevation to the original wetland elevations, soil preparation (ripping/disking), and
revegetating with native canopy species. Additionally, select portions of the Little Contentnea
Creek dredge pile will be excavated to Little Contentnea Creeks top of bank elevation allowing
overflow events to directly influence hydrology within the proposed wetland restoration areas.
The goal of the restoration efforts is to restore wetland vegetation and hydrology to the
previously filled Bib and Tuckerman soils.
i
10.2 Soils
All soils utilized for construction activities within the Farmville Golf & Country Club Mitigation
Site will consist of in situ soils. Prior to planting wetland vegetation, all restoration area soils
will be analyzed to ensure appropriate nutrient concentrations and pH is present. Appropriate
soil amendments will be added, if necessary, to ensure successful growth of all planted
vegetation.
f
10.3 Vegetation
The proposed restoration areas will be planted with trees in the form of bare-root stock. All
plantings will be performed between December 1 and March 15 while stock is dormant.
All trees will be planted within the proposed Coastal Plain Small Stream Swamp (Blackwater
Subtype) area to provide a minimum stem count of 680 stems per acre. This translates to
planting on approximately 8-foot centers. Tree species to be planted will be consistent with
those species located within the reference wetlands and derived from the following list (as
available):
Ironwood (Carpinus caroliniana)
River birch (Betula nigra)
Overcup oak (Quercus lyrata)
EEP 19 March 2006
P
FARMVILLE GOLF & COUNTRY CLUB MITIGATIONSITE RESTORATIONPLAN
Willow oak (Quercus phellos)
Laurel oak (Quercus laurifolia)
Swamp chestnut oak (Quercus michauxii)
Swamp tupelo (Nyssa biflora)
Bald cypress (Taxodium distichum var. distichum)
American elm (Ulmus americana)
10.4 Wetland Preservation
The preservation component for the Site will consist of preserving 1.3 acres of an existing
Coastal Plain Small Stream Swamp (Blackwater Subtype) wetland system.
11.0 WETLAND MONITORING PLAN
Monitoring of wetland restoration efforts will be performed for five years or until success criteria
are satisfied. Monitoring is proposed for two wetland components, hydrology and vegetation.
11.1 Hydrology
Automated monitoring gauges utilized to monitor the Site's groundwater hydrology will be
designed and placed in accordance with specifications in the Corps of Engineers' Installing
Monitoring Wells/Piezometers in Wetlands (WRP Technical Note HY-IA-3.1, August, 1993).
The monitoring gauges installed will consist of Remote Data Systems, Inc. model EcotoneTM
j WM Series automated groundwater monitoring gauges, or acceptable equivalents. These gauges
will continuously record water level data along a 40-inch gradient.
11.1.1 Monitoring
EcotoneTM WM Series (40-in) automated groundwater monitoring gauges will be installed within
the restored wetland areas to determine hydrologic success. Following installation, the
automated groundwater gauges will be adjusted to record data once daily. The gauges will be in
E operation throughout the year, and data will be downloaded at intervals sufficiently spaced to
provide effective monitoring and assessment of success criteria for wetland hydrology.
11.1.2 Success Criteria
Wetland hydrology success criterion will be satisfied in the restoration areas during average
climatic conditions when saturated soil conditions occur within 12 inches (30 centimeters) of the
grounds surface for
• 12.5% of the growing season, or if the hydroperiod is within 20% of the average for
reference gauges within the riverine wetlands.
EEP 20 March 2006
s
FARMYILLE GOLF & COUNTRY CLUB MITIGAY70NSITE RESTORATIONPLAN
11.2 Vegetation
Monitoring methods for vegetation within mitigation areas have been developed in accordance
with Corps of Engineers Branch Guidance for Wetlands Compensation Permit Conditions and
Performance Criteria (1995). A general discussion of the compensatory vegetation-monitoring
plan is provided in the following sections.
11.2.1 Monitoring
Five 20-foot x 20-foot quantitative sampling plots for vegetation will be established in the
wetland restoration areas. Upon completion of planting, an evaluation will be performed to
determine the initial species composition and density. Subsequent quantitative sampling of
vegetation plots will be performed after each growing season until vegetation success criteria is
achieved. Permanent photography stations will be established at selected vantage points to
provide a visual record of vegetation development over time. All vegetation monitoring plots
will be correlated with hydrological monitoring sites where possible to allow for point-source
data of hydrologic and vegetation parameters.
11.2.2 Success Criteria
Wetland vegetation success criterion is defined by a minimum mean density of 320 trees per acre
of approved target species surviving for the first three years. The required success criteria will
decrease by 10% per year after the third year to 290 stems per acre for year four and 260 stems
per acre for year five.
11.3 Report Submittals
As-built plans will be submitted within 90 days following the completion of mitigation
construction. The as-built plans will show final site grading along with a description of post-
planting site conditions. Additionally, a discussion of the planting program will be provided that
includes the species planted, species densities, and number of stems planted. The report will also
provide a map of groundwater monitoring gauge locations, proposed photographic monitoring
stations and proposed vegetation sampling plots.
The first year monitoring report will be submitted to EEP in pdf format. The report will follow
the most current version of EEP's monitoring report format requirements. Subsequent
monitoring reports will be submitted by EEP annually to the resource agencies following each
growing season. Submitted reports will include (1) sample plot data, (2) water level data from
automated groundwater monitoring gauges, and (3) a discussion of substantiated problems and
proposed recommendations for problem resolution. Density, survival and percent composition
of targeted tree species will be reported. The duration of wetland hydrology during the growing
season will also be calculated at each monitoring gauge location and extrapolated to each
EEP 21 March 2006

restored community. The above mentioned monitoring features, monitoring data collection, and
monitoring data summarization will be conducted in accordance with the most current version of
the EEP document entitled "Content, Format, and Data Requirements for EEP Monitoring
Reports".
• 11.4 Contingency
• In the event that vegetation and/or hydrology success criteria are not fulfilled, appropriate
contingency measures will be implemented in coordination with the Resource Agencies.
Examples of such actions include replanting and extension of the monitoring period if
community mitigation types do not fulfill minimum species density and distribution
requirements. Hydrologic contingency will require consultation with hydrologists and the
Resource agencies in the event that predicted hydrology is not achieved during the monitoring
period. Recommendations for altering hydrology to establish wetland hydrology will be
implemented and monitored until the hydrology success criteria are achieved.

INTRODUCTION
i
The North Carolina Ecosystem Enhancement Program (NCEEP) proposes to
.
restore impaired sections of Little Contentnea Creek of the Neuse River Basin within the
f
confines of the Farmville i
Course near Farmville in Pitt County, North Carolina
(Figure 1). The federally endangered Tar spinymussel (Elliptio steinstansana) is listed
by the US Fish and Wildlife Service (USFWS) as occurring in Pitt County. Historically,
the Tar spinymussel is known from the mainstem of the Tar River (of the Tar River
Basin) in Pitt County at Falkland. The Tar spinymussel is also known from the Neuse
River Basin in Johnston County. While not listed for the Pitt County, the federally
. endangered dwarf wedgemussel is documented from the Tar River Basin (Chicod Creek)
in Pitt County (Johnson 1970) and is known from tributaries to the Contentnea Creek
subbasin in Nash, Johnston, land Wilson counties (Moccasin and Turkey Creeks). Thus,
the dwarf wedgemussel is addressed in this report as well. In addition to the Tar
spinymussel and dwarf wedgemussel, there are several other rare freshwater mussel
species that may occur in the Neuse River Basin in Pitt County. These include the
Atlantic pigtoe (Fusconaia masoni), yellow lance (Elliptio lanceolata), yellow
lampmussel (Lampsilis cariosa), green floater (Lasmigona subviridis), triangle floater
. (Alasmidonta undulata), creeper (Strophitus undulatus), and eastern lampmussel
(Lampsilis radiata). The Atlantic pigtoe, yellow lance, yellow lampmussel, and green
floater are Federal Species of Concern and are considered Endangered in North Carolina.
. The triangle floater, creeper, 'I nd eastern lampmussel are considered Threatened in North
. Carolina.
WATERS IMPACTED: Little Contentnea Creek
. The proposed project will impact Little Contentnea Creek, which arises
approximately 13 river miles ?RM) to the northwest of the project crossing in Wilson
County, North Carolina. Approximately 19 RM downstream and southeast of the project
. crossing, Little Contentnea Creek joins the mainstem Contentnea Creek which joins the
mainstem Neuse River south of Grifton, NC. Within the surveyed reach, Little
Contentnea Creek ranges from%5 to 6 meters (16-20 feet) wide with 1-2 meter (3-7 foot)
high banks. The substrate in the surveyed portion of Little Contentnea Creek is
dominated by shifting sand with incised clay banks.
I
The stream runs through the Farmville Country Club Golf Course, which is where
the proposed restoration reach occurs. Little to no riparian vegetation occurs adjacent to
. the creek within the proposed restoration reach. The left descending bank is unstable and
severely eroded in places throughout the restoration reach. The right descending bank
has a narrow strip of riparian vegetation through much of the proposed restoration reach.
This bank shows moderate signs of erosion throughout most of the restoration reach, but
. is severely eroded in places, particularly near golf cart crossings of the creek. Water
depth within the restoration reach is fairly constant and was approximately 1 foot deep
during the site visit.

An approximately 400 meters reach of the stream was surveyed downstream of the
proposed restoration reach. The stream in this reach is forested on both sides of the creek,
with similar dimensions as the restoration reach. The banks are fairly incised in this area,
but with only limited amounts of erosion. A small beaver (Castor canadensis) dam
occurs within the lower 1/3 of this reach. Maximum water depth at the time of site visit
was 2.5 feet near the dam.
A 100 meter section of the creek upstream of the proposed restoration reach was
also surveyed. The stream is forested on both sides of the creek in this section, and is
approximately 16 feet wide with 7 feet high banks. The stream is fairly incised, with
moderately eroded banks. Water depth ranged from 2-5 feet in this reach at the time of
the site visit. A large amount of woody debris and detritus occurs on the stream bottom
in this section of the creek.
SPECIES DESCRIPTIONS
Elliptio steinstansana (Tar spinymussel)
Status: Endangered
Listed: 7/29/85
Characteristics
The Tar spinymussel (TSM) grows to a maximum length of 60 millimeters. Short
spines are arranged in a radial row anterior to the posterior ridge on one valve and
symmetrical to the other valve. The shell is generally smooth in texture with as many as
12 spines that project perpendicularly from the surface and curve slightly ventrally.
However, adult specimens tend to lose their spines as they mature (USFWS 1992c). The
TSM is distinguished by its shiny periostricum, parallel pseudocardinal teeth, and the
linear ridges on the inside surface of the shell.
Little is known about the reproductive biology of the TSM (USFWS 1992a),
however, nearly all freshwater mussel species have similar reproductive strategies, which
involves a larval stage (glochidium), that becomes a temporary obligatory parasite on a
fish. Many mussel species have specific fish hosts which must be present to complete
their life cycle. McMahon and Bogan (2001) and Pennak (1989) should be consulted for
a general overview of freshwater mussel reproductive biology.
Distribution and Habitat Requirements
Previously this mussel was believed to be endemic to the Tar River system,
currently occurring in relatively short stretches of the Tar River and three creeks (Shocco,
Sandy/Swift and Fishing/Little Fishing) in the Tar drainage. Historically the TSM was
collected in the Tar River from near Louisburg in Franklin County to Falkland in Pitt
County (approximately 78 river miles). Clarke (1983) located TSM in only a 12-mile
stretch of the Tar River in Edgecombe County. Recently (1998) the TSM was found in
the Little River of the Neuse River Basin. The preferred habitat of the TSM in Swift

Creek was described as relatively fast flowing, well oxygenated, circumneutral pH water
in sites prone to significant swings in water velocity, with a substrate comprised of
relatively silt-free loose gravel and/or coarse sand.
Threats to Species
The cumulative effects of several factors, including sedimentation, point and non-
point discharge, stream modifications (impoundments, channelization, etc.) have
contributed to the decline of this species throughout its range. The remaining populations
of TSM are generally small in numbers. The low numbers of individuals and the
restricted range of most of the surviving populations make them extremely vulnerable to
extirpation from a single catastrophic event or activity (Strayer et al. 1996). Catastrophic
events may consist of natural events such as flooding or drought, as well as human
influenced events such as toxic spills associated with highways or railroads.
Siltation resulting from improper erosion control of various land usage, including
agricultural, forestry and development activities has been recognized as a major
contributing factor to degradation of mussel populations (USFWS 1996). Siltation has
been documented to be extremely detrimental to mussel populations by degrading
substrate and water quality, increasing potential exposure to other pollutants, and by
direct smothering of mussels (Ellis 1936, Marking and Bills 1979). Sediment
accumulations of less than one inch have been shown to cause high mortality in most
mussel species (Ellis 1936). In Massachusetts, a bridge construction project decimated a
population of the federally endangered dwarf wedgemussel (Alasmidonta heterodon),
because of accelerated sedimentation and erosion (Smith 1981).
Sewage treatment effluent has been documented to significantly affect the
diversity and abundance of mussel fauna (Goudreau et al. 1988). Goudreau et al. (1988)
found that recovery of mussel populations may not occur for up to two miles below
points of chlorinated sewage effluent.
The impact of impoundments on freshwater mussels has been well documented
(USFWS 1992a, Neves 1993). Construction of dams transforms lotic habitats into lentic
habitats, which results in changes with aquatic community composition. The changes
associated with inundation adversely affect both adult and juvenile mussels as well as
fish community structure, which could eliminate possible fish hosts for glochidia.
Muscle Shoals on the Tennessee River in northern Alabama, once the richest site for
naiads (mussels) in the world, is now at the bottom of Wilson Reservoir and covered with
19 feet of muck (USFWS 1992b). Large portions of all of the river basins within the
DWM's range have been impounded and this is believed to be a major factor contributing
to the species decline (Master 1986, USFWS 1993).
The introduction of exotic species such as the Asiatic clam (Corbicula fluminea)
and zebra mussel (Dreissena polymorpha) has also been shown to pose significant threats
to native freshwater mussels. The Asiatic clam is now established in most of the major

supporting surviving populations of the TSM. Concern has been raised over competitive
interactions for space, food and oxygen with this species and native mussels, possibly at
the juvenile stages (Neves and Widlak 1987, Alderman 1997). The zebra mussel, native
to the drainage basins of the Black, Caspian and Aral Seas, is an exotic freshwater mussel
h
t
at was introduced into the Great Lakes in the 1980s and has rapidly expanded its range
into the surrounding river basins, including those of the South Atlantic slope (O'Neill and
. MacNeill 1991). This species competes for food resources and space with native
mussels, and is expected to contribute to the extinction of at least 20 freshwater mussel
species if it becomes established throughout most of the eastern United States (USFWS
1992b). The zebra mussel is not currently known from any river supporting TSM
populations.
0 Alasmidonta heterodon (dwarf wedgemussel)
. Status: Endangered
. Family: Unionidae
Listed: March-14-1990
. Characteristics
The dwarf wedgemussel (Alasmidonta heterodon) (DWM) was originally
described as Unio heterodon (Lea 1829). Simpson (1914) subsequently placed it in the
genus Alasmidonta. Ortmann (1914) placed it in a monotypic subgenus Prolasmidonta,
based on the unique soft-tissue anatomy and conchology. Fuller (1977) believed the
characters of Prolasmidonta warranted elevation to full generic rank and renamed the
species Prolasmidonta heterodon. Clarke (1981) retained the genus name Alasmidonta
and considered Prolasmidonta to be a subjective synonym of the subgenus Pressodonta
(Simpson 1900).
The specific epithet heterodon, refers to the chief distinguishing characteristic of
. this species, which is the only North American freshwater mussel that consistently has
two lateral teeth on the right valve and only one on the left (Fuller 1977). All other
laterally dentate freshwater mussels in North America normally have two lateral teeth on
the left valve and one on the right. The DWM is generally small, with a shell length
. ranging between 25 mm and 38 mm. The largest specimen ever recorded was 56.5 mm
long, taken from the Ashuelot River in New Hampshire (Clarke 1981). The periostracum
is generally olive green to dark brown; nacre bluish to silvery white, turning to cream or
salmon colored towards the umbonal cavities. Sexual dimorphism occurs in DWM, with
the females having a swollen region on the posterior slope, and the males are generally
. flattened. Clarke (1981) provides a detailed description of the species.
Little is known about the reproductive biology of the DWM; however nearly all
. freshwater mussel species have similar reproductive strategies, which involves a larval
stage (glochidium), that becomes a temporary obligatory parasite on a fish. Many mussel
species have specific fish hosts, which must be present to complete their life cycle. Based
i upon laboratory infestation experiments, Michaelson (1993) determined that potential
fish hosts for the DWM in North Carolina include the tesselated darter (Etheostoma

olmstedi) and the Johnny darter (E. nigrum). McMahon and Bogan (2001) and Pennak
(1989) should be consulted for a general overview of freshwater mussel reproductive
biology.
Distribution and Habitat Requirements
The historic range of the DWM was confined to Atlantic slope drainages from the
Peticodiac River in New Brunswick, Canada, south to the Neuse River, North Carolina.
Occurrence records exist from at least 70 locations, encompassing 15 major drainages, in
11 states and 1 Canadian Province (USFWS 1993). It is currently believed to have been
extirpated from all but 36 localities, 14 of them in North Carolina (USFWS 1993).
Strayer et al. (1996) conducted range-wide assessments of remaining DWM populations,
and assigned a population status, to each of the populations. The status rating is based on
range size, number of individuals and evidence of reproduction. Seven of the 20
populations assessed are considered "poor", and two others are considered "poor to fair"
and "fair to poor" respectively. In North Carolina populations are found in portions of the
Neuse and Tar River basins.
The DWM inhabits creeks and rivers of varying sizes (down to approximately 2
meters wide), with slow to moderate flow. A variety of preferred substrates have been
described that range from coarse sand, to firm muddy sand to gravel (USFWS 1993). In
North Carolina they often occur within submerged root mats along stable streambanks.
The wide range of substrate types used by this species suggests that the stability of the
substrate is likely as important as the composition.
Threats to Species
The cumulative effects of several factors, including sedimentation, point and non-
point discharge, stream modifications (impoundments, channelization, etc.) have
contributed to the decline of this species throughout its range. With the exception of the
Neversink River population in New York, which has an estimated population of over
80,000 mussels, all of the other populations are generally small in numbers and restricted
to short reaches of isolated streams. The low numbers of individuals and the restricted
range of most of the surviving populations make them extremely vulnerable to extirpation
from a single catastrophic event or activity (Strayer et al. 1996). Catastrophic events may
consist of natural events such as flooding or drought, as well as human influenced events
such as toxic spills associated with highways or railroads. Other threats are similar to
those described above for TSM.
SURVEY EFFORTS
Little Contentnea Creek is a perennial stream that could potentially provide
habitat for the Tar spinymussel and dwarf wedgemussel, thus surveys for these and other
freshwater mussel species were conducted for NCEEP.

Pre Survey Investigation
Prior to conducting in-stream surveys, a review the North Carolina Natural
Heritage Program (NHP) systematic inventory (database) was consulted to determine if
there are any records of rare plant and animal species within a one-mile area around the
proposed project study area. This review indicated there are no known occurrences of
any federally protected species within the project study area.
Mussel Surveys for this Project
Tim Savidge, Shay Garriock, and Steve Melin of The Catena Group, Inc. visited
the project crossing on June 14, 2005. Mussel surveys were conducted from a point
approximately 400 meters downstream of the project site to a point approximately 100
meters upstream of the site.
Methodology and Results
Visual (using batiscopes and mask/snorkel) and tactile methods were used to
survey for mussels within the entire reach. Water levels during the survey ranged from
less than 1 foot to 5 feet deep. Mussels were identified, counted and returned to the
substrate. The surveyed reach was divided into 3 portions, downstream of the proposed
restoration reach, within the proposed restoration reach, and above the proposed
restoration reach. Data points were taken at the starting point and ending point within
each surveyed reach. Timed searches were conducted in each survey reach for a total of
12.5 person/hours. At least three species of freshwater mussels were found during survey
efforts (Table 1). The introduced Asian clam (Corbicula fluminea) and the aquatic snail
pointed campeloma were common throughout the surveyed area. The Tar spinymussel
and dwarf wedgemussel were not found during the June 14, 2005 survey.

i Because of the taxonomic uncertainty of the genus Elliptio, all elliptio mussels of the Elliptio
complanata and E. icterina complexes were lumped into 1 group. Several distinct forms were
noted, with gradation between each form, making separation difficult. It is very possible that two
to three species comprise the elliptio fauna Little Contentnea Creek.

Discussion
The survey results indicate that a viable mussel population of each of the species
found exists in the surveyed portion of Little Contentnea Creek. Mussels are abundant
and fairly evenly distributed in the creek within the downstream and resoration reaches of
Little Contentnea Creek. Mussels are fairly sparse in the upstream reach, which is likely
a function of the abundant woody debris covering the substrate in this section of the
I creek. The creek has obviously been channelized and straightened the enire length of the
surveyed reach, and is generally unsuitable for the Tar spinymussel and dwarf
wedgemussel. It can be concluded that project construction will have "No Effect" on
these species.
The freshwater mussel species present in the stream are wide ranging habitat
generalists that can tolerate a wide range of habitat conditions. In-stream construction
activities associated with the proposed restoration will likely result in loss of individuals
of these species. However, given their adaptability to a wide range of habitat conditions,
and their abundance downstream, they should be able to quickly recolonize the stream
segment once the restoration is complete. Measures should be taken to avoid/minimize
impacts to the water quality of Little Contentna Creek in order to protect the mussel
populations and other aquatic fauna downstream from project construction.
