EXECUTIVE SUMMARY
The North Carolina Ecosystem Enhancement Program (EEP) proposes to enhance 2,025 LF and
preserve 2,464 LF of perennial stream and restore and enhance 11.9 acres (ac) of wetlands in
Union County, NC (Table ES 1) The streams proposed for restoration include Crooked Creek, a
fourth order stream, as well as unnamed first order tributaries to Crooked Creek (UT) The
project is being completed to provide stream mitigation units (SMUs) and wetland mitigation
units (WMUs) in the Yadkin River Basin The project streams ultimately flow into the Rocky
River which is part of the Yadkin River Basin

attributed to the streams impaired aquatic health. EEP targeted the Rocky River Watershed for
water quality and habitat improvements due to the impacts from agricultural land uses and
anticipated residential growth. The restoration of Crooked Creek and its UTs will correspond
with the goals identified in the RBRP by increasing bank stability, reducing erosion, eliminating
a direct nutrient source to the stream and downstream recreational areas by establishing riparian
vegetation, and enhancing aquatic and terrestrial habitat
The proposed project will provide numerous ecological benefits within the Yadkin River Basin
as listed in Table ES 2 While many of these benefits are limited to the Crooked Creek #2
project area, others, such as pollutant removal, reduced sediment loading, and improved aquatic
and terrestrial habitat have more far - reaching effects. '

1.0 Restoration Project Goals and Objectives
The overall goal of this project is to maximize the ecological improvement of Crooked Creek by
modifying the existing stream channels and wetlands on the site. The existing stream channels
have been impaired by cattle and show signs of erosion and unstable banks. The existing
wetlands have also been impaired by cattle and drained by ditches.
A Phase I Local Watershed Plan (LWP) has been completed for Crooked Creek
(http / /www nceep net/services /lwps/ Goose_ Crooked/ GandC- CrkPhl_SummaryReport_FINAL-
WithAttach.pdf) The LWP presents preliminary characterizations of watershed conditions,
analyzes possible causes of stream impairment, and identifies preliminary priority areas for
projects or additional assessment The project site is located in subwatershed CC4 according to
the delineation presented in the LWP The project site is highlighted as a potential wetland
restoration opportunity in Figure 27 of the LWP. The majbr stressors in the CC4 subwatershed
were identified as urbanization, lack of unprotected land, and agricultural activities
The goals of the Crooked Creek #2 Restoration Project address stressors identified in the LWP
and include the following•
• Improve water quality
• Reduce stream bank erosion
• Improve aquatic habitat
The project goals will be addressed through the following project objectives
• Stream bank grading and stabilization using bio- engineering structures
• Planting the riparian buffer with native species
• Restoring and enhancing wetlands in the floodplain of Crooked Creek
2.0 Site Selection
2.1 Directions
The proposed Crooked Creek #2 Restoration Project is located off NC Highway 218 in the
northern portion of Union County, NC (Figure 1). The site is approximately 7 miles east of the
intersection of NC Highway 218 and Interstate 485 in Mecklenburg County, NC. The proposed
project is located in an active cattle pasture surrounded by woods and small agricultural
operations
From US -74 East, take 27 East/Albemarle Road Travel on Albemarle Road approximately 8
miles to Interstate 485 Take Interstate 485 South (Inner Loop) for approximately 3 miles to exit
44 for NC Highway 218 toward Mint Hill. Turn left off ramp on to NC218 and follow for
approximately 7 miles The project site is located approximately 0 85 miles after US
601 /Concord Highway on the right hand side of the road.
2.2 Site Selection
The Crooked Creek #2 Restoration Project was originally identified for its restoration potential
by EEP The Crooked Creek #2 Restoration Project totals 54 acres, and is located within three
(3) tracts of land One tract of land is owned by Reuben and Lorna Price and the other two (2)
Crooked Creek #2 Restoration Project
Mitigation Plan Page 7

tracts are owned by Logan and Mildred Tucker. A conservation easement has been recorded on
the 54 -acre project study area within the three tracts (Figure 6) The conservation easement is
held by the State of North Carolina and allows for the restoration and enhancement work to
occur and protects the project area in perpetuity This site has historically been used for
agricultural operations No restoration efforts have occurred on the site at this time.
EEP proposes to enhance 2,025 LF and preserve 2,464 LF of perennial and intermittent stream.
In addition, EEP will restore and enhance 119 acres of wetlands in Union County, NC The
project includes Crooked Creek, at least a fourth order stream, as well as unnamed first order
tributaries to Crooked Creek (UT2, and UT3) The project streams ultimately flow into the
Rocky River which is part of the Yadkin River Basin
2.3 Vicinity Map
The Crooked Creek #2 Restoration Project streams are located within Yadkin River Basin
(USGS Hydrologic Unit 03040105 and 03040105040010) as shown in Figure 1 Crooked Creek
(NCDWQ Index No 13- 17 -20) and its UTs are located within Yadkin -Pee Dee River Subbasin
(NCDWQ Subbasin 03- 07 -12) Crooked Creek is the main tributary of the project and is at least
a fourth order stream UT2, and UT3 are first order streams that flow into Crooked Creek
The North Carolina Division of Water Quality (NCDWQ) assigns best usage classifications to
State Waters that reflect water quality conditions and potential resource usage. Crooked Creek
(NCDWQ Index No 13- 17 -20) is the main tributary of the project and has been classified as
Class C waters Class C waters are protected for secondary recreation, fishing, wildlife, fish and
aquatic life propagation and survival, agriculture, and other uses.
2.4 Watershed Map
The proposed Crooked Creek #2 Restoration Project is located in the northern portion of Union
County in the Yadkin River Basin (USGS Hydrologic Unit 03040105). At the downstream
limits of the project, the drainage area of Crooked Creek is 24,619 acres (38 47 square miles).
Drainage areas for the project reaches were determined by delineating watersheds on the USGS
7.5- minute topographic quadrangle (Figures 2a and 2b) The drainage areas and land uses are
summarized in Table 1

rolling, well rounded hills with long low ridges, with elevations ranging anywhere from 300 to
1500 feet above sea level. The Carolina Slate Belt consists of heated and deformed volcanic and
sedimentary rocks Approximately 550 to 650 million years ago, this region was the site of a
series of oceamc volcamc islands The belt is known for its numerous abandoned gold mines
and prospects Specifically, the proposed restoration site is located in the metamudstone and
meta - argillite (CZmd) mapped unit of the Carolina Slate Belt composed of Ordovician and
Cambrian -aged rock These rock types are described as thin to thick bedded and interbedded
with metasandstone, metaconglomerate, and metavolcamc rock (NCGS, 2009) A significant
slate outcropping exists along the right bank of Crooked Creek Reach B and along UT3 The
outcroppings along Crooked Creek extend an average height of 6 foot from the channel bed for
approximately 100 LF and exhibit horizontal veins. Slate bedrock is present in the channel
bottom of UT3 and along its banks near the confluence with Crooked Creek
2.5 Soil Survey
Soil mapping units are based on the U S. Department of Agriculture (USDA) Natural Resource
Conservation Service (MRCS) Soil Survey for Union County. Soil types within the study area
include Chewacla silt loam (ChA), Badin channery silt loam (BaB and BaQ, Badin channery
silty clay loam (BdB2), and Cid channery silt loam (CmB) Chewacla soils are somewhat
poorly - drained, found mainly within valleys and floodplains, exhibit moderate permeability and
are frequently flooded. Chewacla soils are listed by the NRCS as having inclusions of hydric
soils for Union County Badin soils are typically found on hillslopes, interfluves, and ridges, are
well - drained, and exhibit moderately high permeability. Cid soils are moderately well - drained,
typically found on uplands and interfluves, and exhibit moderately low permeability These soils
are described below in Table 2 A soils map is provided in Figure 3

An investigation of the existing soils on the wetland restoration /enhancement/creation site was
performed by WEI on July 1, 2011. This investigation supplemented the soils analysis
performed by WEI between June 8 and June 10, 2011. Soil cores were collected at locations
across the site to provide data to refine NRCS soils mapping units, establish areas suitable for
wetland restoration, and aid in developing a wetland restoration plan Forty-eight soil cores
were taken at approximately 100 to 200 -foot grid spacing across the site at varying depths The
cores were taken to a depth at which either hydric soil features or groundwater was
encountered. Soil texture; Munsell chart hue, chroma, and value, and hydric soil characteristics
were recorded for each core The depth to hydric indicators and groundwater table, if
attainable, was then measured at each core Data for these forty-eight soil borings as well as a
map showing their locations is included in Figure 4 and Appendix B.
2.6 Current Condition Plan View
On May 19, 2011, Wildlands Engineering, Inc (WEI) investigated 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
and subsequent Eastern Mountain and Piedmont Regional Supplement. Determination methods
included stream classification utilizing the NCDWQ Stream Identification Form and the USACE
Stream Quality Assessment Worksheet Potential jurisdictional wetland areas as well as typical
upland areas were classified using the USACE Wetland Determination Data Form
The results of the on -site field investigation indicate that there are three jurisdictional stream
channels located within the proposed project area including Crooked Creek and two unnamed
tributaries (UT2, and UT3) to Crooked Creek Five jurisdictional wetland areas were identified
within the proposed project area (Wetlands AA — EE) and are located within the floodplain of
Crooked Creek Routine Determination Forms representative of on -site jurisdictional wetlands
as well as non jurisdictional upland areas have been enclosed in Appendix B (DPI -DP6). Site
photographs are included in Appendix C, taken at locations as indicated in Figure 4.
2.7 Historical Condition Plan View
The Yadkin 03040105 watershed includes some of the fastest developing areas in the region at
the Union County and Mecklenburg County line along US -74 Development is expected to
continue to increase, which will pose a significant threat to water quality Portions of Crooked
Creek are currently listed as impaired under Section 303(d) of the Clean Water Act. Point and
non -point sources attributable to urbanization and agriculture have resulted in the watershed's
poor water quality rating Population growth and the associated development and infrastructure
projects create the necessity for mitigation projects in this region
The project site includes two first -order streams and one fourth -order stream The watershed to
UT2 is dominated by agricultural land uses including open pasture and a poultry operation
located immediately to the northeast of the project site The watershed to UT3 also provides a
limited footprint for future development and drains open pastures and a partially- forested area
located south of Crooked Creek. The Crooked Creek watershed is located outside the town
limits of Fairview. Land use within the Crooked Creek watershed is historically rural and
dominated by forest and agriculture and is approximately 38% agricultural, 29% forested, 28%
developed, 3% wetlands, and 2% herbaceous upland.

The Crooked Creek site is located in the mapped 100 -year floodplain of Crooked Creek (Figure
5). While the conservation easement will primarily discourage future development, the 100 -year
floodplain adds further protection against development outside the conservation easement

4.1 Watershed Summary Information
Crooked Creek (NCDWQ Index No 13- 17 -20) and its UTs are located within Yadkin -Pee Dee
River Subbasm (NCDWQ Subbasin 03- 07 -12) Crooked Creek is the main tributary of the
project and is at least a fourth order stream. UT2, and UT3 are first order streams that flow into
Crooked Creek The project area is located within a local watershed plan, as described below.
EEP, along with community stakeholders, Centralma COGG, and Tetra Tech, have developed
potential restoration needs and protection strategies to address EEP's objectives and meet the
mitigation needs of the Goose and Crooked Creek watersheds
(http //www gooseandcrooked.org /index.php)
EEP develops local watershed plans (LWP) for specific priority areas where critical watershed
issues need to be addressed. These LWPs describe projects and management strategies to
restore, enhance, or protect local water resources. The Crooked Creek #2 Restoration Project is
Crooked Creek #2 Restoration Project
Mitigation Plan Page 13

currently located within an area covered by an LWP, the Goose Creek and Crooked Creek Local
Watershed Plan Phase 1. Biological communities within Crooked Creek have been listed as poor
due to impaired water quality Stressors such as construction, stormwater runoff, and
agricultural use have attributed to the streams' impaired aquatic health
(http. / /www nceep net/services /lwps/ Goose_ Crooked/ GandC- CrkPhI_SummaryReport_FINAL-
WithAttach.pdf)
EEP also develops River Basin Restoration Priorities (RBRPs) to guide its restoration activities
within each of the state's 54 cataloging units. RBRPs delineate specific watersheds that exhibit
both the need and opportunity for wetland, stream and riparian buffer restoration These
watersheds are called Targeted Local Watersheds (TLWs) and receive priority for EEP planning
and restoration project funds The 2009 Lower Yadkin Pee -Dee RBRP identified HUC
03040105040010, which contains the Crooked Creek #2 Restoration Project
(http / /www nceep. net / services /restplans /Yadkin_ Pee_ Dee_RBRP 2009_Final.pdf). EEP
targeted the Rocky River Watershed for water quality and habitat improvements due to the
impacts from agricultural land uses and anticipated residential growth. The restoration,
enhancement, and preservation of Crooked Creek and its UTs will correspond with the goals
identified in the RBRPs by increasing bank stability, reducing erosion, eliminating a direct
nutrient source to the stream and downstream recreational areas, and enhancing aquatic and
terrestrial habitat
4.2 Reach Summary Information
Crooked Creek is the primary tributary draining the project area from west to east. The Crooked
Creek system has a 38 47- square mile drainage area and was classified as perennial, relatively
permanent water (RPW). RPWs are defined by the USACE Approved Jurisdictional
Determination Form as channels that typically flow year -round or have continuous flow at least
seasonally This channel exhibits average bankfull widths of 35 to 60 feet, access to a large
well - developed floodplam, well- defined riffle -pool sequences, and substrate consisting of large
cobble Portions of Crooked Creek within the project area exhibit moderate to extensive bank
erosion from cattle activity and low water farm equipment crossings In addition to these over -
widened areas, several large intermittent overflow channels have developed immediately
adjacent to the main channel The majority of the project reach exhibits well- shaded in- stream
habitat from a well- developed canopy layer However, where vertical, bare, and overhanging
banks exist, very little understory vegetation growth has occurred, resulting in additional bank
instability Biological sampling within this channel revealed an abundant presence of fish, a
moderate presence of benthic macromvertebrates and aquatic mollusks, and a weak presence of
crayfish and amphibians Macroinvertebrate sampling was performed as a visual observation as
part of the NCDWQ and USACE stream assessment protocols, a formal collection and
evaluation was not performed at the time of this investigation Crooked Creek scored 73 out of a
possible 100 points on the USACE Stream Assessment Form and scored 52 out of 63 possible
points on the NCDWQ Stream Classification Form, indicating perennial status (SCP4, enclosed
in Appendix B) Stream assessment forms representative of the intermittent overflow channels
have also been included (SCP5)
UT2 to Crooked Creek drains a 51 -acre watershed northeast of the project The upstream portion
of UT2 was classified as an intermittent RPW and exhibits average bankfull widths of 6 to 8 feet,
Crooked Creek #2 Restoration Project
Mitigation Plan Page 14

moderate sinuosity, minimal groundwater flow, and substrate consisting of fine sand and gravel
The intermittent portion of this reach scored 38 out of a possible 100 points on the USACE
Stream Assessment Form and scored 24 25 out of 63 possible points on the NCDWQ Stream
Classification Form, indicating intermittent status (SCP2). UT2 transitions to a perennial RPW
at the confluence with Wetland CC with a total drainage area of approximately 51 acres This
portion of UT2 exhibits bankfull widths of 6 to 10 feet, contributing groundwater flow, poor
profile diversity, and substrate consisting of gravel to small cobbles The entire length of UT2
shows impacts from cattle access and grazing including trampled banks and bed incision.
Riparian habitat is similarly degraded from cattle activities and includes a well - developed
canopy layer with little to no understory stabilizing vegetation Biological sampling of the
perennial portion of this reach indicated a low presence of benthic macroinvertebrates and
amphibians This portion of UT2 scored 49 out of a possible 100 points on the USACE Stream
Assessment Form and scored 38 out of 63 possible points on the NCDWQ Stream Classification
Form, indicating perennial status (SCP3)
UT3 to Crooked Creek is a small intermittent RPW that drains an area located south of the
project approximately 38 acres in size. UT3 exhibits average bankfull widths of 5 to 8 feet,
recent alluvial deposits, organic debris piles, and a well - defined natural valley The on -site
portion of this channel is located entirely within a forested riparian area and is in moderately
good condition with stable bed and banks due to lack of cattle access and maintenance. UT3
scored 45 out of a possible 100 points on the USACE Stream Assessment Form and scored 22 5
out of 63 possible points on the NCDWQ Stream Classification Form, indicating intermittent
status (SCP6) A copy of the Jurisdictional Determination is included in Appendix B
A copy of all stream and wetland assessment forms are located in Appendix B along with a map
showing stream and wetland data collection points in Figure 8
4.2.1 Channel Classification
Crooked Creek Reach A is located in a wide valley and is not extremely incised, with an
entrenchment ratio greater than 2 2 Cattle trampling is the primary reason for moderate
vertical incision and widened banks along Reach A. The shallow depth and wide banks
provides a width -to -depth ratio close to 37 The bed material appears to be dominated by
gravel and cobble as well as a small -grain fraction
Crooked Creek Reach B is less incised than Reach A, leading to lower bank height ratios and
higher entrenchment ratios This reach is deeper than and not as wide as Reach A, with a
width -to -depth ratio close to 16. Like Reach A, bed material appears to be dominated by
gravel and cobble as well as a small -grain fraction
UT2 to Crooked Creek is slightly entrenched and exhibits low width -to -depth ratios. The
channel appears to have been altered and straightened, so sinuosity cannot be used for
classification
UT3 to Crooked Creek has a steep slope (5 88 %) and low sinuosity The reach enters
Crooked Creek on the right bank hillside section

geomorphic survey data Detailed geomorphic surveys were not conducted on UT2 since a

42.3 Discharge
Design discharges for the reaches on the project site were not developed since preservation
and enhancement II are proposed
424 Channel Morphology
Existing conditions channel morphology surveys were performed to document the current
condition of the streams on the Crooked Creek site and to provide a basis for the design.
Overall, channelization of the streams and surrounding agricultural land use has led to
channel incision, severe bank erosion, and loss of aquatic habitat. It is likely that all of these
streams originally had higher entrenchment values and frequently accessed their floodplains
Overall, Reaches A and B of Crooked Creek are over -wide in some locations, but not
extremely vertically incised with well - defined riffle -pool sequences, and substrate consisting
of large cobble Bank height ratios typically range from 1 1 to 16 Portions of Crooked
Creek Reach A exhibit moderate to extensive bank erosion from cattle activity and low water
farm equipment crossings The landowner verbally confirmed this cattle activity stating that
the cattle typically congregate on the south side of Crooked Creek in the shade of the mature
hardwoods. Most of the floodplam is populated with mature hardwoods which provide
ample shade along the stream However, where vertical, bare, and overhanging banks exist,
very little understory vegetation growth has occurred, resulting in additional bank instability
Along Crooked Creek Reach B, the majority of the reach exhibits stable vegetated banks,
minor incision, and a hardwood canopy The stream appears to frequently access an
adequate floodplain with the exception of approximately 340 LF where the right bank is up
against a hillside The section that is adjacent to the hillside is stable due to bedrock
outcroppings and mature vegetation
42.5 Channel Evolution
A review of aerial photos for the project area dating back to 1948 indicates that the unnamed
tributaries to Crooked Creek were channelized and much of the woody vegetation along the
channels was removed prior to that time The pattern and vegetation along Crooked Creek
seem to have remained the same since then However, the contributing watershed to
Crooked Creek cover has changed at a fast pace little since the early 1970's and continues to
Crooked Creek #2 Restoration Project
Mitigation Plan Page 18

be one of the fastest developing areas in the region at the Union County and Mecklenburg
County line along US -74 Historic channelization, on -going agricultural practices, and
development have attributed to the streams' impaired aquatic health in the Crooked Creek
Watershed Urbanization within the Crooked Creek watershed is expected to continue. Bank
grading and stabilization and the installation of a proper pool cross section will help to offset
the effects of urbanization
Along Crooked Creek Reach A, the channel banks have been continuously trampled and
widened by cattle activity The channel appears to be aggrading as evidenced by several
mid - channel bars Removal of cattle, grading and stabilization of eroding banks, and
restoration of a woody vegetated buffer will help to stabilize the channel thereby reducing in-
stream sediment erosion and deposition. The enhancement II approach will address the
problem spots along the channel while preserving the positive features such as the mature
hardwood buffer
4.2.6 Channel Stability Assessment
Crooked Creek's primary destabilizing cause is cattle access Bank height ratios range from
1 1 to 16. The removal of cattle access, creation of a stable channel cross - section and
pattern, and the addition of woody vegetation for bank protection will help to protect this
reach from further degradation.
UT2 receives runoff from an intermittent channel to the northeast and from the existing
wetland CC The channel is somewhat incised and has a few sections of unstable banks UT2
is relatively straight with gravel /cobble substrate Stabilizing eroded banks and establishing
bank vegetation will preserve several mature hardwoods.
UT3 is a steep, moderately entrenched intermittent channel that to the south of Crooked
Creek The charnel flows through the hillside along the right bank of Crooked Creek that is
dominated with slate outcroppings The slate bedrock with horizontal veins stabilizes the
channel while mature vegetation stabilizes the banks The straight pattern and low width to
depth ratio are most likely influenced by the presence of slate outcroppings
4.2.7 Bankfull Verification
Bankfull stage indicators on the project streams were few and difficult to identify due to
incision of the channels and trampling of the banks by livestock However, during the
existing conditions assessment, WEI staff identified the best available bankfull indicators and
surveyed cross sections at those locations. Bankfull indicators included flat depositional
features and prominent breaks in slope.
Bankfull data for the surveyed project reaches and nearby reference reaches were compared
with the NC rural Piedmont regional curves and are shown overlaid with the rural curves for
area and discharge in Figure 9 Analysis of the bankfull cross - sectional areas and discharges
for the project reaches reveal that the data consistently plot within the 95% confidence
intervals of the area and discharge regional curves in all cases where the points are within the
range of drainage area (independent variable) covered by the regional curves This
information indicates that the bankfull indicators identified during the existing conditions
assessment provide reasonable estimates of bankfull geometry for the existing conditions
Crooked Creek #2 Restoration Project
Mitigation Plan Page 19

4.2.8 Vegetation Community Types Descriptions
Vegetation habitats within the project area are primarily comprised of open pastures -
dominated by various graminoid and herbaceous species, in addition to areas of mature
mixed hardwood trees with few pockets of invasive vine and shrub species The open areas
within the site have been heavily mowed and maintained as active cattle pastures. These
areas completely lack canopy, sub - canopy, and understory shrub layers and are dominated by
buttercup (Ranunculus bulbosus), soft stem rush (Juncus effuses), curly dock (Rumex
crispus), smartweed (Polygonum pensylvaracum), purple deadnettle (Lamium purureum),
perennial ryegrass (Lolium perenne), Nepalese browntop (Microstegium vimzneum), and
white clover (Trifohum repense)
The stream banks of Crooked Creek and its adjacent floodplain exhibit hardwood tree species
typical of a mesic mixed hardwood forest or bottomland forest (Schafale and Weakley,
1990) These areas exhibit a well - developed, mature canopy layer, however, they lack a true
sub - canopy, shrub, and herbaceous layers due to persistent cattle access and impacts from
grazing Typical canopy species include box elder (Acer negundo), American sycamore
(Platanus occidentahs), red maple (Acer rubrum), southern red oak (Quercus falcata), green
ash (Fraxinus pennsylvanica), red elm (Ulmus rubra), and ironwood (Carpinus carohana).
4.3 Wetland Summary Information
4.3.1 Jurisdictional Wetlands
On May 19, 2011, Wildlands Engineering investigated and delineated on -site jurisdictional
waters of the U.S using the USACE Routine On -Site Determination Method. This method is
defined by the 1987 Corps of Engineers Delineation Manual and subsequent Eastern
Mountain and Piedmont Regional Supplement Guide The results of the on -site jurisdictional
determination indicate that there are five jurisdictional wetland areas located within and
adjacent to the floodplain of Crooked Creek and UT (Wetlands AA — EE).
Wetland AA is located in the north portion of the project area and is approximately 1.1 acres
in size. This jurisdictional system was classified as a partially ditched palustrme emergent
(PEM) wetland and exhibited surface water from 1 to 4 inches, water - stained vegetation,
oxidized rhizospheres, low chroma soils (7 5YR 511), many distinct mottles (5YR 4/6), and
saturation in the upper 12 inches of the soil profile Existing soil conditions are indicative of
a Depleted Matrix (F3 hydric soil indicator) Wetland AA is located in an active cattle
pasture and portions of this wetland have been ditched to allow for increased surface
drainage.
Wetland BB is palustrme emergent (PEM) system located in the active pasture west of
Wetland AA and is approximately 0.1 acre in size. This jurisdictional feature is the result of
past ditching efforts to remove excess water from these agricultural areas This system is a
linear conveyance that exhibited pockets of surface water, water - stained vegetation, oxidized
rhizospheres, low chroma soils (7 5YR 511), many distinct concentrations (5YR 4/4), and
saturation in the upper 12 inches of the soil profile
Wetland CC is a ditched/linear wetland complex that receives drainage from both Wetlands
AA and BB and is approximately 0.4 acre in size. This wetland complex is the result of past
ditching efforts along with existing floodplain depressions that have been heavily trampled
Crooked Creek #2 Restoration Project
Mitigation Plan Page 20

from cattle activity and incision from flooding events. Portions of this feature exhibit deep,
stagnant surface water from 2 to 3 feet, ultimately leading to a direct surface water
connection with UT2 The remainder of Wetland CC exhibited sediment deposits, drainage
patterns, an algal mat, water - stained leaves, oxidized rhizospheres, low chroma soils (5YR
511), distinct iron concentrations (7 5YR 4/6), and saturation within the upper 12 inches of
the soil profile
Wetlands DD and EE are located in the eastern portion of the project area adjacent to
Crooked Creek and are approximately 0.03 and 0 05 acre in size, respectively. These small
linear wetlands are classified as palustrme emergent (PEM) and exhibited impacts from cattle
trampling and grazing Typical wetland indicators include pockets of surface water up to 3
inches, drainage patterns, sediment deposits, oxidized rhizospheres, low chroma soils (IOYR
4/2 and 2 5Y 5/2), distinct concentrations (5YR 4/6), and saturation within the upper 12
inches of the soil profile Wetland Determination Data Forms representative of these
jurisdictional wetland areas have been enclosed in Appendix B (DP 1, DP3, DP5, and DP6)
Based on a similar geomorphic reference area and nearby vegetation communities, it was
determined that these jurisdictional systems historically functioned as Bottomland Hardwood
Forests, prior to their conversion to agricultural pasture An assessment of these wetlands
was performed according to the recent North Carolina Wetland Assessment Method
( NCWAM) in order to determine their level of hydrologic function, water quality, and habitat
condition Due to heavy agricultural activities over the past several decades along with
aggressive vegetation management, these wetland systems scored out as low functioning
- systems when compared to reference conditions Particularly low scoring parameters include
the effects from ditching on decreased surface and subsurface hydrology Additionally,
vegetation management has reduced aquatic and terrestrial habitat along with eliminating the
systems' connection to adjacent natural habitats. An NCWAM Wetland Rating Sheet
representative of these jurisdictional wetland areas is enclosed in Appendix B (AA — EE)
4.3.2 Hydrological Characterization
In order to develop a wetland restoration and enhancement design for the Crooked Creek
Mitigation Site, an analysis of the existing and proposed conditions for groundwater
hydrology was necessary DrainMod (version 6 0) was used to model existing and proposed
groundwater hydrology at the site DrainMod simulates water table depth over time and
produces statistics describing long term water table characteristics and an annual water
budget DramMod was selected for this application because it is a well - documented
modeling tool for assessing wetland hydrology (NCSU, 2010) and is commonly used in
wetland restoration projects For more information on DramMod and its application to high
water table soils see Skaggs (1980)
4.3.2.1 Groundwater Modeling
For the Crooked Creek wetland site, two models were developed to represent the existing
and proposed conditions at two different gauge locations — gauges GWG4 and GWG6 —
on the site. Resulting model output was used to validate the proposed plan for wetland
restoration on site and to develop a water budget for the site The modeling procedures
are described below
Data Collection
Crooked Creek #2 Restoration Project
Mitigation Plan Page 21

DramMod models are built using site hydrology, soil, climate, and crop data Prior to
building the models, soil cores were taken to validate existing mapped soils across the -
site. Further explanation of the site soils can be found in section 4.3.3 of this report
Rainfall and temperature data were obtained from nearby weather station Monroe 2 SE
(Station No. 315771) operated by the National Oceanic and Atmospheric Administration
(NOAA) National Weather Service. The data set for this station was obtained from the
North Carolina State Climate Office from January of 1935 through July of 2011 These
data were used to test the models and performance against observed data and perform the
long term simulations Information to develop model inputs for vegetation on the site
was obtained through interviews with the landowner and review of historical aerial
photos
Existing Conditions Base Model Setup and Calibration
Models were created to represent two monitoring gauge locations on the site at as shown
on Figure 7. The models were developed using the conventional drainage water
management option to best simulate the drainage of the site Each of the two gauges was
installed in late May 2011 and recorded groundwater depth once per day with Ecotone
water level monitoring gauges through early August 2011
The first step in developing the model was to prepare input files from various data
sources. A soil input file obtained from N C. State University, which has similar
characteristics to the soils on the site, was used as a base soil input file for each model
Temperature and precipitation data from a nearby weather station, described above, were
used to produce weather input files for each model The existing drainage characteristics
for the site were input into the model along with information on site vegetation and
climate The site has been used for grazing cattle so no crop data were necessary
Once the necessary input files were created, the project settings were adjusted for this
application to represent the site conditions as well as possible The groundwater
monitoring data collected between May and August 2011 were not adequate to calibrate
the models at this time The data for gauge GWG4 does not show any groundwater
hydrology during the monitoring period. The data for gauge GWG6 shows only two
short periods where the groundwater was present above the bottom of the well In
addition, the nearest rain gauge to the site (Monroe 2 SE) is over 10 miles away and
analysis of other nearby gauges showed quite different rainfall patterns for the monitoring
period of May through August 2011. This indicates that the rainfall data from Station
No 315771 is questionable to represent the rainfall at the site Due to lack of appropriate
data, the existing conditions model could not be calibrated The groundwater gauges will
be left in place and replaced if necessary and a recording rain gauge will be set up at the
site in order to provide data for future model calibration Appendix B shows plots of the
uncalibrated existing conditions models and the groundwater monitoring and rainfall data
for the Monroe 2 SE station
Proposed Conditions Model Setup
The proposed conditions models were developed based on the existing conditions models
to predict whether wetland criteria would be met over a long period of recorded climate
data Proposed plans for the site include minimal grading of less than 6 inches in a few
Crooked Creek #2 Restoration Project
Mitigation Plan Page 22

locations, removing a system of existing agricultural ditches that currently drain portions
of the site, planting native wetland plants, and roughing the surface soil through disking.
These proposed plans were developed to increase the wetland hydrology in drained
hydric soils on site Settings for the proposed conditions model were altered to reflect
these changes to the site Filling of the existing agricultural ditches on the site was
simulated by increasing the drain spacing for each of the two gauges. Changes in the
vegetation on the site were simulated by altering the rooting depth of plants on the site
from relatively shallow depths for pasture grasses to deeper values for hardwood tree
species Surface storage values were increased at all gauges to account for proposed
disking to the site Because proposed grading is of minimal depth and in only a few
locations, the ground surface elevation were not altered Once the proposed conditions
models were developed, each model was run for a 76 -year period from January 1935
through December 2010 using the weather data from the Monroe 2 SE weather station to
perform the long term simulation.
Modeling Results and Conclusions
DrainMod was used to compare uncalibrated existing conditions models with proposed
conditions scenarios to estimate the effect of proposed practices on site hydrology. Two
gauge locations were evaluated to establish how often annual wetland criteria would be
met over the 76 -year simulation period The wetland criteria are that the water table must
be continuously within 12 inches of the ground surface at each gauge for a minimum of a
certain percentage of the growing season (March 23 through November 6). This
_ minimum percentage is increased with each model run to a point where results start to
decrease rapidly. Using a rmmmum percentage of 6.5% of the growing season, the
modeling results show that Gauges GWG4 and GWG6 would meet the criteria 69 years
and 68 years respectively out of the 76 -year period following restoration activities Using
percentages above 6 5% showed the number of years predicted to meet hydrology
dropped rapidly Therefore, 6 5% of the growing season was chosen as the target
hydrology success criteria This success criteria represents the hydrology modeled for a
mature forest which will not be achieved until well after the monitoring period These
results will be refined when a calibrated model is available at a later time
4.3.2.2 Surface Water Modeling at Restoration Site
No other modeling of surface hydrology, other than the HEC -RAS hydraulic flood study,
was performed for this project
4.3.2.3 Hydrologic Budget for Restoration Site
DrainMod computes daily water balance information and outputs summaries that
describe the loss pathways for rainfall over the model simulation period Tables 8a and
8b summarize the average annual amount of rainfall, surface runoff, infiltration,
subsurface drainage, and evapotranspiration estimated for the two modeled locations on
site Runoff is water that flows overland and reaches the drainage ditches before
infiltration. Infiltration represents the amount of water that percolates into the soil
Runoff and infiltration are equal to precipitation. Drainage is the loss of infiltrated water
that travels through the soil profile and is discharged to the drainage ditches or to
underlying aquifers Evapotranspiration (ET) is water that is lost by the direct
Crooked Creek #2 Restoration Project
Mitigation Plan Page 23

evaporation of water from the soil or through the transpiration of plants From the water
balance results provided in Tables 8a and 8b, it is clear that most rainfall on the site, for
existing and proposed conditions, is lost via ET. For GWG4, the proposed modifications
to the site result in a significant decrease in runoff (and increased infiltration) with
increases in ET and subsurface drainage. However, for GEG6, there is essentially no
change in runoff or infiltration but a decrease in subsurface drainage and increase in ET
So the source of increased hydrology for GWG4 is a significant decrease in water lost
through runoff on the site For GWG6, existing conditions runoff is relatively low but
improved wetland hydrology is provided by a decrease in subsurface drainage along with
little to no increase in surface runoff

4.3.3 Soil Characterization
An investigation of the existing soils on the wetland restoration/enhancement site was
performed by WEI between June 8 and June 10, 2011, and on August 1, 2011. This
investigation supplemented the soils analysis performed by a licensed soil scientist (LSS) on
October 26, 2011. Soil cores were collected at locations across the site to provide data to
refine NRCS soils mapping units, establish areas suitable for wetland restoration, and aid in
developing a wetland restoration plan. WEI took forty-eight soil cores at approximately 100
to 200 -foot grid spacing across the site at varying depths The cores were taken to a depth at
which either hydric soil features or groundwater was encountered. Soil texture, Munsell chart
hue, chroma, and value, and hydric soil characteristics were recorded for each core. The
depth to hydric indicators and groundwater table, if attainable, was then measured at each
core Soils were also evaluated at six additional locations around the site during the wetland
delineation described above The soil core data from these six locations were added to the 48
grid- spaced cores and the 16 cores taken by the LSS for a total of 70 cores in the soil core
data base for the site The most recent 48 soil cores taken by WEI and the 16 cores taken by
the LSS along with the mapped soil units are shown on Figure 4 The data for each core is
included in Appendix B.
4.3.3.1 Taxonomic Classification
Two soils types are mapped within the boundaries of the jurisdictional wetland areas in
the Natural Resources Conservation Service (MRCS) Soil Survey (MRCS, 2009) Much
of the site is mapped as Chewacla silt loam (ChA) while the northern portions of
Wetlands AA, CC, and DD are mapped as Badin channery silt loam (BaC) Analysis of
the soil core samples collected from the project site along with consideration of site
—r topography indicated that soil classifications at the 48 core locations largely agreed with
the mapped soil units however they more closely matched the Wehadkee soil inclusions
listed for Chewacla soils The Chewacla silt loam is listed as a Type B soil for Union
County, indicating a small portion of the series has inclusions of hydric indicators
Chewacla soils are somewhat poorly drained and frequently flooded. Analysis of the
core data indicates that the soils on the site mapped as Chewacla exhibited a lower
chroma matrix and other hydric indicators in areas of poor drainage and flat topography
The Badin series is not listed on the NC hydric soil list and is a well drained soil type
Jurisdictional wetland areas located within this soil type can be attributed to their location
within the floodplain at the toe of slope where shallow groundwater is present
4.3.3.2 Profile Description
The Chewacla series is described in the NRCS official series description as a piedmont
and coastal plain floodplain soil that is very deep, somewhat poorly drained found on
zero to two percent slopes. The typical texture profile of Chewacla soils is a medium
granular loam at zero to four inches, a silty clay loam from four to 14 inches, and loam/
clay loam layering from 14 to 80 inches The Badin series is described as a moderately
deep, well drained soil The Badin series is found on gently sloping to steep uplands in
the piedmont. The texture profile of Badin soils is channery silt loam from zero to six
inches, channery silty clay loam from six to nine inches, silty clay from nine to 18 inches,
channery silty clay loam from 18 to 25 inches, and weathered highly- fractured
metasedimentary rock from 25 to 40 inches.
Crooked Creek #2 Restoration Project
Mitigation Plan Page 25

4.3.3.3 Hydraulic Conductivity
The Chewacla series has a moderately high to high Ksat value ranging from 0.57 to 198
in/hr It is somewhat poorly drained and typically has a water table depth of six to 24
inches The Badm series has a very low to high Ksat value ranging from 0 00 to 198
in/hr It is well drained and generally has low available water capacity
4.3.4 Vegetation Community Types Descriptions and Disturbance History
The existing vegetation communities within the on -site jurisdictional wetland area are
representative of a stressed Palustrme Emergent system (Cowardin, 1979) Based on
historical aerial photographs, farming activities and cattle pastures have been prevalent in
this area since at least 1948 (Appendix B) Due to persistent cattle grazing and vegetation
management over the past several decades, several mayor strata are completely absent from
this area resulting in a dominant herbaceous layer with no mature trees present within
Wetlands AA, BB, and CC. Wetlands DD and EE maintain a well - developed canopy layer,
however active cattle grazing has completely removed native understory vegetation.
Dominant herbaceous species within these areas includes buttercup (Ranunculus bulbosus),
soft stem rush (Juncus effuses), curly dock (Rumex crispus), and various grass species.
4.4 Regulatory Considerations
4.4.1 Endangered and Threatened Species
The Endangered Species Act (ESA) of 1973, amended (16 U S.0 1531 et seq ), defines
protection for species with the Federal Classification of Threatened (T) or Endangered (E).
An "Endangered Species" is defined as "any species which is in danger of extinction
throughout all or a significant portion of its range" and a "Threatened Species" is defined as
"any species which is likely to become an Endangered Species within the foreseeable future
throughout all or a significant portion of its range" (16 U S C. 1532)
WEI utilized the U.S Fish and Wildlife Service (USFWS) and North Carolina Natural
Heritage Program (NHP) databases in order to identify federally listed Threatened and
Endangered plant and animal species for Union County, NC (USFWS, 2008 and NHP,
2009) Three federally listed species, the Carolina heelsplitter (Lasmzgona decorate),
Michaux's sumac (Rhus mzchauxu), and Schwemitz's sunflower (Hehanthus schweinitzu)
are currently listed in Union County (Table 9) The approved Categorical Exclusion
Checklist for the project is included in Appendix B

E = Endangered, T= Threatened
4.4.1.1 Species Description
Carolina Heelsplitter
The Carolina heelsplitter is a freshwater mussel with an ovate trapezoidal shell ranging
from 3 to 4 inches in length. This species requires cool, clean, well- oxygenated water
with stable, silt -free stream bottoms as apparent critical habitat Typical threats to this
species include common pollutants from municipal and industrial wastewater discharges
as well as sedimentation and runoff from agricultural and forestry operations. This
species is known to exist within two small tributaries in North Carolina around the
Mecklenburg County/ Union County line
Michaux's Sumac
Michaux's sumac is a densely hairy shrub with serrated compound leaves that grows
from 3 to 10 feet in height These plants are found in disturbed, sandy, or rocky open
woods with basic soil types Typical habitat may also include road rights -of -way and
edges of artificially maintained clearings This plant is threatened by habitat destruction
from residential and industrial development as well as fire suppression.
Schweinitz's Sunflower
Schweinitz's sunflower is a perennial herb ranging from 3 to 6 feet tall with yellow disk
and ray flowers This species is typically found in open areas where disturbance has
occurred such as roadsides, power line clearings, old pastures and woodland openings
This species is generally found growing in shallow, poor, clayey, and/or rocky soils
4.4.1.2 Biological Conclusion
A pedestrian survey of the site was performed on May 19, 2011 On -site habitats include
active agricultural pastures and open, wooded riparian areas There is no suitable habitat
for the Carolina heelsplitter in the project area The majority of Crooked Creek within
the project area is moderately affected by cattle access which has resulted in stream bank
instabilities, sedimentation, and water turbidity. There are somewhat suitable open and
artificially maintained areas within the project area for the presence of Michaux's sumac
and Schweinitz's sunflower, however due to active cattle grazing and mowing, along
with acidic soil conditions, on -site habitats are unable to support either of these species
Crooked Creek #2 Restoration Project
Mitigation Plan
Page 27

As a result of the pedestrian survey, it is determined that no Federally - listed individual
species were found to exist on the site and that the proposed restoration activities will
have "no effect" on these Endangered species
442 Federal Designated Critical Habitat
4.4.2.1 Habitat Description
Habitat for the Carolina heelsplitter includes cool, clean, well- oxygenated water with
stable, silt -free stream bottoms of creeks and rivers Individuals can be found in areas
with permanently flowing, cool, clean water, geomorphically stable stream bed and
banks, and stable substrates with low amounts of fine sediment According to the
USFWS database, designated critical habitat for the Carolina heelsplitter exists within
Union County. These areas include the main stem of Goose Creek from the NC Highway
218 Bridge, downstream to its confluence with the Rocky River and the main stem of
Duck Creek, from the Mecklenburg County/Union County line, downstream to its
confluence with Goose Creek Additional Critical Habitat with Union County includes
the main stem of Waxhaw Creek (Catawba River Basin) from the NC Highway 200
Bridge downstream to the North Carolina/South Carolina State line
4.4.2.2 Biological Conclusion
Designated Critical Habitat for the Carolina heelsplitter is not located within or
downstream of the project watershed area of Crooked Creek It is therefore determined
that the proposed project will have "no effect" on the designated critical habitat
4.4.3 Cultural Resources
The National Historic Preservation Act (NHPA) of 1966, as amended (16 U S.0 470),
defines the policy of historic preservation to protect, restore, and reuse districts, sites,
structures, and objects significant in American history, architecture, and culture. Section 106
of the NHPA mandates that federal agencies take into account the effect of an undertaking on
any property that is included in, or is eligible for inclusion in, the National Register of
Historic Places A letter was sent to the North Carolina State Historic Preservation Office
(SHPO) on May 26, 2011, requesting review and comment for the potential of cultural
resources potentially affected by the Crooked Creek project The SHPO responded on June
23, 2011, and stated they were aware of no historic resources which would be affected by the
project A Categorical Exclusion Checklist for the project is included in Appendix B
44.4 FEMA and Hydrologic Trespass
Crooked Creek is mapped as a FEMA Zone AE floodplain on Firm panel 5540. Base flood
elevations have been defined and the floodway has been delineated and is mapped on the
FIRM panel
The effective hydraulic model for the mapped floodplain will be obtained from the NC
Floodplain Mapping Program WEI will model existing and proposed hydraulic conditions
on the site for the 100 -year flood event along Crooked Creek. If appropriate, a Conditional
Letter of Map Revision (CLOMR) will be prepared for submittal to the Union County local
floodplain administrator and the NC Floodplam Mapping Program for approval prior to
construction If hydraulic modeling indicates that the 100 -year flood elevation will not
Crooked Creek #2 Restoration Project
Mitigation Plan Page 28

increase, then a no -rise study will be submitted. Following construction completion, if a
CLOMR was required or a no -rise indicates that flood elevations will drop by more than 0.1
foot, an as -built survey and Letter of Map Revision (LOMR) will be finalized and submitted
to the Union County local floodplam administrator and the NC Floodplain Mapping
Program Steep hill slopes should prevent off -site flooding adjacent to the wetland
restoration areas
5.0 Determination of Credits
Mitigation credits presented in Table 10 are projections based upon site design Upon
completion of site construction the project components and credits data will be revised to be
consistent with the as -built condition

6.0 Determination of Credits
All credit releases will be based on the total credit generated as reported by the as -built survey of
the mitigation site Under no circumstances shall any mitigation project be debited until the
necessary DA authorization has been received for its construction or the District Engineer (DE)
has otherwise provided written approval for the pojrect in the case where no DA authorization is
required for construction of the mitigation project. The DE, in consultation with the Interagency
Review Team (IRT) will determine if performance standards have been satisfied sufficiently to
meet the requirements of the release schedules below. In cases where some performance
standards have not been met credits may still be released depending on the specifics of the case
Monitoring may be required to restart or be extended, depending on the extent to which the site
fails to meet the specified performance standard. The release of project credits will be subject to

7.0 Mitigation Work Plan
The restoration design developed for this project was completed with careful consideration of
goals and objectives that were described in the LWP and RBRP (Section 4.1). The goals were
established to meet NCEEP's mitigation needs while maximizing the ecological and water
quality uplift provided by the project The goals represent the "ends" that the finer objectives (or
"means ") were formulated to achieve and were directed by the specific stressors discussed
above The overarching goals of this mitigation plan are broad and similar to those of other
mitigation plans The objectives are more specific in order to replace specific ecological
functions and to remain sustainable given watershed trajectory
7.0.1 Overarching Goals of Mitigation Plans
The overall goal of this project is to maximize the ecological improvement of Crooked Creek
by modifying the existing stream channels and wetlands on the site The existing stream
channels have been impaired by cattle and show signs of erosion and unstable banks The
existing wetlands have also been impaired by cattle and drained by ditches The Crooked
Creek #2 Restoration Project has been designed to meet the over - arching goals described
above. The project will also address multiple watershed stressors that have been documented
for both Crooked Creek and the Goose Creek watersheds The project specific goals include•
• Improve wetland hydrologic connectivity
• Create appropriate in- stream habitat
• Decrease sediment input into stream
• Create appropriate terrestrial habitat
• Decrease water temperature and increase dissolved oxygen concentrations
• Decrease nutrient and adverse chemical levels
7.02 Mitigation Project Goals and Objectives
The design features of this project were developed to achieve multiple project objectives
The stream restoration elements have been designed to frequently flood the reconnected
floodplain and adjacent riparian wetlands. This design will provide more frequent
dissipation of energy from higher flows (bankfull and above) to improve channel stability;
provide water quality treatment through detention, settling, and biological removal of
pollutants, and restore a more natural hydrologic regime Existing, restored, and created
wetlands are key components of the design incorporated to better meet goals described
above The project objectives have been defined as follows
Crooked Creek #2 Restoration Project
Mitigation Plan Page 32

• Repair stream channels that will remain relatively stable over time.
- • Provide aquatic and benthic habitat diversity in the form of pools, riffles, woody debris,
and in- stream structures.
• Add riffle features and structures and riparian vegetation to decrease water temperatures
and increase dissolved oxygen to improve water quality
• Construct fencing to keep livestock out of the streams
• Raise local groundwater table by plugging agricultural drainage features
• Perform minor grading in wetland areas as necessary to promote wetland hydrology.
• Plant native tree species to establish appropriate wetland and floodplain communities and
retain existing, native trees where possible
7.1 Target Wetland Types and Plant Communities
7.1.1 Target Stream Type(s)
Reference reaches can be used as a basis for design or, more appropriately, as one source of
information on which to base a stream restoration design. Most, if not all, reference reaches
identified in the North Carolina Piedmont are in heavily wooded areas and the mature
vegetation contributes greatly to their stability Geomorphic design parameters have not
developed for Crooked Creek Reach A or UT2 since enhancement II is proposed
71.2 Target Wetland Type(s)
The wetland elements of this project include the following (Figure 14)
Zone A This area encompasses drained hydric soils in the floodplain surrounding existing
Wetlands AA and BB. The existing ditches that drain a portion of Wetland AA and comprise
Wetland BB will be plugged in order to restore hydrology to this portion of the floodplain
and the area will be planted with native hydrophytic tree and shrub species. The plugging of
these wetland ditches will result in a total of 0 25 acre of temporary wetland impacts It is
anticipated that plugging the existing ditches will raise the groundwater table to within 12
inches of the ground surface and will achieve hydrology criteria for the minimum length of
the growing season Wetland areas will be disked to increase surface roughness to better
capture rainfall and to improve connection with the water table for groundwater recharge.
The specific percentage of the growing season meeting this hydrologic criterion will be more
accurately determined based on the future assessment of groundwater gauge data. Zone A
will include approximately 7 0 acres of wetland restoration and 0.7 acre of wetland
enhancement This area will be restored to a Piedmont Bottomland Forest (Shafale and
Weakley, 1990)
Zone B This area is comprised of a linear ditch feature (Wetland CC) and surrounding
upland pasture The existing ditch will be filled in order to eliminate stagnant open water
areas and result in the enhancement of 0.3 acre of existing wetland habitat. This area will be
left lower than the surrounding area composed of non- hydric soils to ensure that wetland
hydrology is maintained. Minimal grading will be performed along the perimeter of the ditch
in order to lay back the vertical banks The surrounding floodplain areas will be disked to
increase surface roughness to better capture rainfall and to improve connection with the

water table for groundwater recharge The entire 4 2 acres of Zone B will be planted with
native shrub and tree species This planted community will also be indicative of a Piedmont
Bottomland Forest WEI will perform post - construction monitoring of the approximately 3 9
acres of area surrounding Wetland CC to determine if groundwater hydrology and soil
conditions improve as a result of the proposed ditch filling and grading Although the soils
analysis indicates that this area does not contain drained hydric soils, the topography and
geomorphic setting indicate that wetland hydrology may return after restoration
7.1.3 Target Wetland and Buffer Plant Communities
The target communities for the restored and enhanced wetlands and riparian buffer zones will
be based on reference conditions The main wetland reference site is a combination of
species indicative of a Piedmont Bottomland Forest and a Piedmont/Low Mountain Alluvial
Forest (Schafale and Weakley, 1990) The reference site is a preserved wetland within a
conservation easement held by the NCEEP located in Cabarrus County along Dutch Buffalo
Creek (Suther Property) Because most of the proposed wetland restoration and
enhancement areas as well as the riparian buffer will have hydrology similar to the reference
wetland site, that community will be the primary target The species to be planted are
described in Section 6 2 2
7.2 Design Parameters
Based on assessments of the watershed and existing channels, the designs have been developed
to correct bank instability caused by erosion and livestock access, lack of vegetation in riparian
zones, lack of riparian and aquatic habitat, and depletion of hydrology for adjacent wetlands All
stream enhancement II reaches included in the design for this project will be constructed as C
type streams according to the Rosgen classification system ( Rosgen, 1996) Type C streams are
slightly entrenched, meandering streams with well - developed floodplains and gentle gradients of
2% or less They occur within a wide range of valley types and are appropriate for the project
landscape The proposed stream and wetland concept design is provided in Figure 14.
7.2 1 Stream Design Parameters
A Rosgen Priority 4 enhancement approach is proposed for Reach A of Crooked Creek while
preservation is proposed for Reach B of Crooked Creek as shown in Figure 10 In- stream log
and rock structures will be installed and bank grading will occur within Reach A to stabilize
eroding banks within the existing channel
Rosgen Priority 4 enhancement is proposed for UT2 Banks will be graded, stabilized, and
vegetated to prevent further erosion Preservation is proposed for UT3 due to its stable
vegetated banks and existing riparian buffer The project will also include the restoration,
preservation, and enhancement of riparian wetland areas adjacent to Crooked Creek and
UT2.
Geomorphic design parameters have not developed for Crooked Creek Reach A or UT2 since
enhancement II is proposed
7.2.2 Wetland and Buffer Plant Design Communities
As a final stage of construction, riparian stream buffers and wetland mitigation zones will be
planted and restored to the dominant natural plant community that exists within the project
watershed. This natural community within and adjacent to the project easement is classified
Crooked Creek #2 Restoration Project
Mitigation Plan Page 34

as Piedmont Bottomland Forest and was determined based on existing canopy and
\_ herbaceous species (Schafale and Weakley, 1990). Proposed plant and seed materials will be
placed on stream banks and bench areas as well as the floodplain, for a total of 18.2 acres of
planting. These areas will be planted with bare root trees, live stakes, and a seed mixture of
permanent herbaceous vegetation ground cover.
A permanent seed mixture of native herbaceous and grass species will be applied to all
disturbed areas within the project easement An herbaceous seed mixture was chosen that
would provide quick stabilization of constructed stream banks, benches, and side slopes
These species will also provide early habitat value through rapid growth of ground cover on
the tops of banks and floodplam areas. Permanent riparian herbaceous species will be
selected from the species listed in Table 14a and 14b

as bare root, live stakes, and containerized plants and will provide additional stabilization to
the outsides of constructed meander bends and side slopes Species planted as bare roots will
spaced at an initial density of 680 plants per acre (8 feet on center) Live stakes will be
planted at 4,840 stakes per acre (3 feet on center) on channel banks Targeted densities after
monitoring year 3 are 320 woody stems per acre Proposed tree and shrub species are
representative of existing on -site vegetation communities and are typical of Piedmont

73 Stream Project and Design Justification
The existing conditions assessment of the project reaches of Crooked Creek and UT2 indicate
that channelization of the streams and livestock operations have resulted in incision and
Crooked Creek #2 Restoration Project
Mitigation Plan Page 36

enlargement of the channels Livestock access is causing lateral erosion and enlargement of the
_ stream cross sections The incision and lateral erosion have also resulted in degraded aquatic and
benthic habitat, altered hydrology (related to loss of floodplain connection and lowered water
table) and reduction of quality and amount of riparian wetlands The enlargement of the
channels has also contributed to water quality problems including lower dissolved oxygen levels
(due to wide channels with shallow flow) Based on assessments of the watershed and existing
channels, designs have been developed to correct bank instability caused by erosion and
livestock access, lack of vegetation in riparian zones, lack of riparian and aquatic habitat, and
depletion of hydrology for adjacent wetlands
Crooked Creek Reach A appears to be aggrading and widening. It is highly unlikely that
Crooked Reach A will progress to equilibrium without excluding the cattle from the stream
Livestock have trampled the banks and created cut -off channels and seem to be the main catalyst
of bank erosion Stream banks will not stabilize solely by excluding livestock; the significant
bank erosion and formation of mid - channel bars and cut -off channels must be addressed by bank
grading and stabilization The least invasive treatment option has been selected to ensure long
term stability
74 Data Analysis
7 4 1 Sediment Transport Analysis
Enhancement II efforts on Crooked Creek Reach A and UT2 are not expected to change the
sediment transport characteristics Therefore, a sediment transport analysis was not
performed

9.0 Monitoring Requirements
Using the EEP Baseline Monitoring Plan Template (version 2 0 10/14/2010), a baseline
monitoring plan report and an as -built record drawing of the project documenting the stream and
wetland restoration and enhancement, will be developed within 60 days of the planting
completion and monitoring installation on the project site Monitoring reports will be prepared
in the fall of each year of monitoring and submitted to NCEEP. These annual monitoring reports
will be based on the NCEEP Monitoring Report Template (version 13, 1/15/2010) and the
NCEEP Momtormg Requirements and Reporting Standards for Stream and /or Wetland
Mitigation (11/07/2011) The monitoring period will extend seven years for stream and wetland
hydrology assessments and seven years for wetland vegetation assessments beyond completion
of construction or until performance criteria have been met The monitoring report shall provide
a project data chronology that will facilitate an understanding of project status and trends,

determine if a bankfull event has occurred Photographs will be used to document the
occurrence of debris lines and sediment deposition
9.2 Vegetation
Vegetation monitoring plots will be installed and evaluated within the restoration and
enhancement areas to measure the survival of the planted trees The number of monitoring
quadrants required is calculated based on the standards described in the EEP monitoring
guidance documents (version 14, 11/7/11) and the EEP Monitoring Requirements and
Performance Standards for Stream and /or Wetland Mitigation (11/7/11) The size of individual
quadrants will be 100 square meters for woody tree species and shrubs. Vegetation assessments
will be conducted following the Carolina Vegetation Survey (CVS) Level 2 Protocol for
Recording Vegetation (2006)
The initial baseline survey will be conducted within 21 days from completion of site planting and
used for subsequent monitoring year comparisons. The first annual vegetation monitoring
activities will commence at the end of the first growing season, during the month of September
The restoration and enhancement sites will then be evaluated each subsequent year between June
1 st and September 315`. Species composition, density, and survival rates will be evaluated on an
annual basis by plot and for the entire site Individual plot data will be provided and will include
diameter, height, density, vigor, damage (if any), and survival Planted woody stems will be
marked annually as needed and given a coordinate, based off of a known origin, so they can be
found in succeeding monitoring years. Mortality will be determined from the difference between
the previous year's living planted stems and the current year's living planted stems
9.3 Wetlands
Groundwater monitoring gauges will be established throughout the wetland restoration and
enhancement areas Generally, the gauges will be installed at appropriate locations so that the
data collected will provide an indication of groundwater levels throughout the wetland project
area

10.0 Performance Standards
The stream restoration success criteria for the project site will follow approved performance
criteria presented in the NCEEP Mitigation Plan Template (version 2 0, 10/1/2011), the NCEEP
Monitoring Requirements and Performance Standards for Stream and/or Wetland Mitigation
(11/7/2011), and the Stream Mitigation Guidelines issued in April 2003 by the USACE and
NCDWQ Annual monitoring and bi- annual site visits will be conducted to assess the condition
of the finished project for seven years, or until success criteria are met The enhancement level
II reaches (Crooked Creek Reach A and UT2) will be documented through photographs and
visual assessments to verify that no significant degradational changes are occurring in the stream
channel or riparian corridor. The wetland restoration and enhancement sections will be assigned
specific performance criteria for hydrology and vegetation. These success criteria are covered in
detail as follows
10.1 Streams
10.11 Dimension
Visual indicators for the riffle cross - sections on the enhancement reaches should illustrate
relative stable channel bed and banks Indicators of instability include a vertically incising
thalweg or eroding channel banks
10.1.2 Pattern and Profile
Visual indicators for the stream restoration reaches should show that the bedform features are
remaining stable The riffles should be steeper and shallower than the pools, while the pools
should be deep with flat water surface slopes The relative percentage of riffles and pools
should not change significantly from the design parameters Adjustments in length and slope
of run and glide features are expected and will not be considered a sign of instability.
10.1.3 Photo Documentation
Photographs should illustrate the site's vegetation and morphological stability on an annual
basis. Permanent station photos should demonstrate no excessive erosion or degradation of
the banks These permanent station photos should also indicate the absence of persistent bars
within the channel or vertical incision Grade control structures should remain stable.
Deposition of sediment on the bank side of vane arms is preferable Maintenance of scour
pools on the channel side of vane arms is expected Reference photos will also be taken for
each of the vegetation plots
10.14 Substrate
A visual observation of the enhancement reaches should indicate a progression towards or
the maintenance of coarser materials in the riffle features and smaller particles in the pool
features
Crooked Creek #2 Restoration Project
Mitigation Plan Page 41

10.1.5 Bankfull Events
Two bankfull flow events in separate years must be documented on the project within the
seven -year monitoring period. Bankfull events will be documented using a crest gauge,
photographs, and visual assessments such as debris lines
10.2 Vegetation
The final vegetative success criteria will be the survival of 210 planted stems per acre in the
riparian corridor along restored and enhanced stream reaches and within the wetland restoration
and enhancement areas at the end of the required monitoring year (year seven) The interim
measure of vegetative success for the site will be the survival of at least 260 planted stems per
acre at the end of the fifth monitoring year and 320 planted stems per acre at the end of the third
monitoring year The extent of invasive species coverage will also be monitored and controlled
as necessary throughout the required monitoring period (year seven)
10.3 Wet /ands
The target performance criteria for wetland hydrology will be a free groundwater surface within
12 inches of the ground surface for 6 5 percent of the growing season, which is measured on
consecutive days under typical precipitation conditions This success criterion was determined
through model simulations of post restoration conditions and comparison to an immediately
adjacent existing wetland system As discussed in Section 4 3 2, the target success criterion will
be refined when model calibrations are completed. If a particular groundwater monitoring gauge
does not meet the success criteria for a given monitoring year, rainfall patterns will be analyzed
and the hydrograph will be compared to that of the reference well to assess whether atypical
weather conditions occurred during the monitoring period
11.0 Long -Term Management Plan
Upon approval for close -out by the Interagency Review Team (IRT) the site will be transferred
to the NCDENR Division of Natural Resource Planning and Conservation and Stewardship
Program This party shall be responsible for periodic inspection of the site to ensure that
restrictions required in the conservation easement or the deed restriction document(s) are upheld
Endowment funds required to uphold easement and deed restrictions shall be negotiated prior to
site transfer to the responsible party
The NCDENR Division of Natural Resource Planning and Conservation's Stewardship Program
currently houses EEP stewardship endowments within the non - reverting, interest - bearing
Conservation Lands Stewardship Endowment Account The use of funds from the Endowment
Account is governed by North Carolina General Statue GS 113A- 232(d)(3) Interest gained by
the endowment fund may be used only for the purpose of stewardship, monitoring, stewardship
administration, and land transaction costs, if applicable The NCDENR Stewardship Program
intends to manage the account as a non - wasting endowment Only interest generated from the
endowment funds will be used to steward the compensatory mitigation sites Interest funds not
used for those purposes will be re- invested in the Endowment Account to offset losses due to
inflation
Crooked Creek #2 Restoration Project
Mitigation Plan Page 42

12.0 Adaptive Management Plan
Upon completion of site construction EEP will implement the post - construction monitoring
protocols previously defined in this document. Project maintenance will be performed as
described previously in this document. If, during the course of annual monitoring it is
determined the site's ability to achieve site performance standards are jeopardized, EEP will
notify the USACE of the need to develop a Plan of Corrective Action The Plan of Corrective
Action may be prepared using in -house technical staff or may require engineering and consulting
services. Once the Corrective Action Plan is prepared and finalized EEP will
1 Notify the USACE as required by the Nationwide 27 permit general conditions.
2 Revise performance standards, maintenance requirements, and monitoring requirements
as necessary and/or required by the USACE
3 Obtain other permits as necessary
4 Implement the Corrective Action Plan
5. Provide the USACE a Record Drawing of Corrective Actions This document shall
depict the extent and nature of the work performed.
13.0 Financial Assurances
Pursuant to Section IV H and Appendix III of the Ecosystem Enhancement Program's In -Lieu
Fee Instrument dated July 28, 2010, the North Carolina Department of Environment and Natural
Resources has provided the US Army Corps of Engineers Wilmington District with a formal
commitment to fund projects to satisfy mitigation requirements assumed by EEP This
commitment provides financial assurance for all mitigation projects implemented by the
program

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.

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.
Total Score (from reverse): 45 Comments:

Boxes checked below shall be supported by completing the appropriate sections in Section 111 below
For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year -round or has continuous flow at least "seasonally"
(e g , typically 3 months)
' Supporting documentation is presented in Section III F

SECTION III. 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 III D 1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2
and Section III.D.1., otherwise, see Section II1.B below

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 Rapanos have 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 III D 2 If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section 111 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 waterbody° 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 HI B.2 for any onsite wetlands, and Section I11 B 3 for all wetlands adjacent to that tributary, both onsite
and offsite The determination whether a significant nexus exists is determined in Section Ill C below

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 carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW9
• 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 TNW9
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs9
• Does the tributary, in combination with its adjacent wetlands (if any) have other relationships to the physical, chemical, or
biological integrity of the TNW9
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below.

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 III D 2 If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section 111 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 waterbody° 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 C below

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 floodplam 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 carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW9
• 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 TNW9
• 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 TNW9

SECTION III: 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 III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2
and Section III DA , otherwise, see Section III.B below

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 Rapanos have 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 III D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III DA
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 waterbody° 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 111.13 1 for
the tributary, Section 111 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 C below.

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

tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplam is not solely determinative of significant nexus
Draw connections between the features documented and the effects on the TNW, as identified in the Rapmtos 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 carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW9
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and Iifecycle support functions for fish and

size of the wetland type (WT), the size of the wetland complex (WC), and the size of the forested wetland (FW) (if applicable, see User
Manual) Seethe User Manual for boundaries of these evaluation areas If assessment area is clear -cut, select "K" for the FW column
WT WC FW (if applicable)
A A A z 500 acres
B B B From 100 to < 500 acres
C C C From 50 to < 100 acres
D D D From 25 to < 50 acres
E E E From 10 to < 25 acres
F F F From 5 to < 10 acres

EH
K < 0 01 acre or assessment area is clear -cut
12 Wetland Intactness —wetland type condition metric (evaluate for Pocosins only)
EA Pocosin is the full extent (Z 90 %) of its natural landscape size
B Pocosin is < 90% of the full extent of its natural landscape size
13 Connectivity to Other Natural Areas — landscape condition metric
13a Check appropriate box(es) (a box may be checked in each column) Involves a GIS effort with field adjustment This metric
evaluates whether the wetland is well connected (Well) and /or loosely connected (Loosely) to the landscape patch, the contiguous
naturally vegetated area and open water (if appropriate) Boundaries are formed by four -lane roads, urban landscapes, maintained
fields (pasture open and agriculture), or water > 300 feet wide
Well Loosely
CA CA z 500 acres
['B [:B From 100 to < 500 acres
C PC From 50 to < 100 acres
D D From 10 to < 50 acres
E E < 10 acres
• F F Wetland type has a poor or no connection to other natural habitats
13b Evaluate for marshes only
riYes ENo Wetland type has a surface hydrology connection to open waters /stream or tidal wetlands
14 Edge Effect — wetland type condition metric
May involve a GIS effort with field adjustment Estimate distance from wetland type boundary to artificial edges Artificial edges include
permanent features such as fields, development, two -lane or larger roads ( z 40 -feet wide), utility line corridors wider than a two -lane road,
and clear -cuts < 10 years old Consider the eight main points of the compass
FA No artificial edge within 150 feet in all directions
• B No artificial edge within 150 feet in four (4) to seven (7) directions
E:C An artificial edge occurs within 150 feet in more than four (4) directions or assessment area is clear -cut
15 Vegetative Composition —assessment area condition metric (skip for all marshes and Pine Flat)
['A Vegetation is close to reference condition in species present and their proportions Lower strata composed of appropriate
species, with exotic plants absent or sparse within the assessment area
�.'B Vegetation is different from reference condition in species diversity or proportions, but still largely composed of native species
characteristic of the wetland type This may include communities of weedy native species that develop after clearcutting or
clearing It also includes communities with exotics present, but not dominant, over a large portion of the expected strata
E:C Vegetation severely altered from reference in composition Expected strata are unnaturally absent or dominated by exotic
species or composed of planted stands of non - characteristic species or inappropriately composed of a single species
16 Vegetative Diversity —assessment area condition metric (evaluate for Non -tidal Freshwater Marsh only)
A Vegetation diversity is high and is composed primarily of native species (00% cover of exotics)
B Vegetation diversity is low or has > 10% to 50% cover of exotics
C Vegetation is dominated by exotic species ( >50% cover of exotics)

17 Vegetative Structure — assessment area /wetland type condition metric
17a Is vegetation present'?
Co Yes C No If Yes, continue to 17b If No, skip to Metric 18
