The Crooked Creek #2 Project is located within Hydrologic Unit Code (HUC) 03040105040010
which was identified as a targeted local watershed in EEP's 2009 Lower Yadkin Pee -Dee River
Basin Restoration Priority Plan Goals for the HUC listed in the RBRP include improved
stormwater management, protection of threatened and endangered wildlife resources, mitigation
of impacts resulting from rapid development, and restoring water quality in impaired streams
The project area is also located within a local watershed planning (LWP) area and the Goose and
Crooked Creeks Watershed Management Plan (WMP) was finalized in July 2012. Mayor
stressors to watershed function identified in the WMP included sediment pollution, increases in
peak stream flows, nonpoint source runoff, degraded terrestrial habitat, and disconnected
floodplains Management opportunities to offset these stressors include stream and wetland
restoration The Crooked Creek #2 Project will help meet the management goals in the RBRP
and WMP documents The site was identified in the WMP as a wetland restoration priority
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 The UT1 restoration design will impact
approximately 0 06 acres of linear wetland that is currently being maintained as an agricultural
ditch This impact can be considered insignificant given that the rest of the linear ditch wetland
will be filled as part of the restoration plan in order to improve wetland hydrology

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 clear cut, impaired by cattle, and drained by ditches
The Crooked Creek #2 Protect Site's watershed is within Hydrologic Unit Code (HUC)
03040105040010 which was identified as a Targeted Local Watershed in EEP's 2009 Lower
Yadkin Pee -Dee River Basin Restoration Priority (RBRP) plan
(http•/ /portal ncdenr.org /c /document_ library/get _fle ?uuid= 081b34ec- 8b4c- 434f -9e25-
57c713cb136c &groupld= 60329) Goals for the HUC listed in the RBRP include improved
stormwater management, protection of threatened and endangered wildlife resources, continued
mitigation of impacts resulting from rapid development, and restoring water quality in impaired
streams Biological communities within the North Fork and South Fork of Crooked Creek have
been listed as poor due to impaired water quality Stressors such as construction, stormwater
runoff, and agricultural use most likely have attributed to the streams impaired aquatic health
EEP targeted this HUC for water quality and habitat improvements due to the impacts from
agricultural land uses and anticipated residential growth
The Crooked Creek #2 Restoration Project is also located within an area covered by the Goose
Creek and Crooked Creek Local Watershed Plan, or LWP (http• / /www gooseandcrooked org).
For the LWP, EEP worked with community stakeholders, Centralina CCOG, and a technical
consultant, Tetra Tech, to identify watershed functional stressors and develop potential
management strategies to direct mitigation project implementation The final watershed
management plan (WMP) was completed by Tetra Tech and CCOG in July 2012
(http•//www gooseandcrooked org/ documents /GooseandCrookedLWP- WMP_Final_7 -2012 pdf)
The most serious stressors to watershed function identified in the WMP were sediment pollution
and increases in peak stream flows Sources of sediment listed in the WMP include construction
sites, agricultural runoff, livestock access to streams, streambank and channel erosion, and
ATVs The problems caused by sediment deposition in channels includes impairments to aquatic
habitat and aquatic life Stream enhancement and restoration is identified as the best
"management opportunity" to offset these impacts Other stressors identified included nonpoint
source runoff, degraded terrestrial habitat, and disconnected floodplains among others Wetland
enhancement and restoration is identified as the best management opportunity to offset impacts
related to these stressors.
The enhancement and restoration work proposed for Crooked Creek and its UTs will correspond
with the goals identified in the RBRP and LWP by increasing bank stability, reducing erosion,
eliminating a direct nutrient source to the stream and downstream recreational areas, and
enhancing aquatic and terrestrial habitat The wetland portion of the proposed project was
identified as a specific priority (ranked as the 19th highest priority in the Goose and Crooked
Creek watersheds) in the Project Atlas that accompanies the 2012 WMP
Crooked Creek #2 Restoration Project
Mitigation Plan Page 7

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 and terrestrial habitat
The project goals will be addressed through the following project objectives
• Excluding cattle access from stream channels
• Restoration of a tributary using natural channel design techniques
• 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 Se lection
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)
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 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 restore 1,718 linear feet (LF) and enhance 4,429 LF of perennial and
intermittent stream In addition, EEP will restore, enhance, and create 11.5 acres of wetlands in
Union County, NC. The project includes Crooked Creek, at least a fourth order stream, as well
as two unnamed first order tributaries to Crooked Creek (UT1 and UT2). The project streams
ultimately flow into the Rocky River which is part of the Yadkin River Basin
Crooked Creek #2 Restoration Project

The Crooked Creek 42 Restoration Project streams are located within Yadkin River Basin
(USGS Hydrologic Unit 03040105 and 03040105040010) as shown in Figure 1 Crooked Creek
(DWQ Index No 13- 17 -20) and its UTs are located within Yadkin -Pee Dee River Subbasin
(DWQ Subbasin 03- 07 -12) Crooked Creek is the main tributary of the project and is at least a
fourth order stream UT1 and UT2 are first order streams that flow into Crooked Creek
The North Carolina Division of Water Quality (DWQ) assigns best usage classifications to State
Waters that reflect water quality conditions and potential resource usage. Crooked Creek (DWQ
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 -mmute topographic quadrangle (Figures 2a and 2b) The drainage areas and land uses are

The Crooked Creek #2 Restoration Project is located in the Carolina Slate Belt of the Piedmont
Physiographic Province (USGS, 1998) The Piedmont Province is characterized by gently
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 oceanic volcanic 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 metavolcanic rock (NCGS, 2009) A significant
slate outcropping exists along the right bank of Crooked Creek Reach B The outcroppings
along Crooked Creek extend an average height of 6 feet from the channel bed for approximately

2.5 Sod 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, mterfluves, 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 Wildlands on July 1, 2011 This investigation supplemented the soils analysis
performed by Wildlands 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 ( Wildlands) 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
Crooked Creek #2 Restoration Project -
Mitigation Plan Page 10

Delineation Manual and subsequent Eastern Mountain and Piedmont Regional Supplement
Determination methods included stream classification utilizing the DWQ 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 four jurisdictional stream
channels located within the proposed project area including Crooked Creek and two unnamed
tributaries (UT1 and UT2) 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 Along UT1, the
(~ off -site watersheds are small and provide a limited footprint where development could impact
- the site 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 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 (DWQ Index No. 13- 17 -20) and its UTs are located within Yadkin -Pee Dee
River Subbasin (DWQ Subbasin 03- 07 -12). Crooked Creek is the main tributary of the project
and is at least a fourth order stream UT1 and UT2 are first order streams that flow into Crooked
Creek The project area is located within a local watershed planning area, as described below.
EEP, along with community stakeholders, Centralina COG, 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
located within an area covered by the Goose Creek and Crooked Creek Local Watershed Plan
Phase 1. Biological communities within the Crooked Creek watershed 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 (Tetra Tech, 2012)
Crooked Creek #2 Restoration Project , -1�
Mitigation Plan Page 14 1 1 ;

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 includes the Crooked Creek #2 Restoration Project
(http / /www nceep net /services /restplans / Yadkm Pee Dee _RBRP_2009_Final pdf). EEP
targeted the this watershed for water quality and habitat improvements due to the impacts from
agricultural land uses and anticipated residential growth The restoration and enhancement of
Crooked Creek and its UTs on the project site 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 floodplain, 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 macroinvertebrates and aquatic mollusks, and a weak presence of
crayfish and amphibians Macroinvertebrate sampling was performed as a visual observation as
part of the DWQ 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 DWQ 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)
UT1 to Crooked Creek drains the northern portion of the project area with a drainage area of
approximately 153 acres UT1 was classified as a perennial RPW and exhibits average bankfull
widths of 8 -10 feet, weak perennial flow conditions, low sinuosity, moderate alluvial deposits,
poor profile diversity, and substrate consisting of silt to small cobbles. This channel exhibits
effects from past ditching efforts A spoil berm exists along the left top of bank throughout the
upper reach along the property line This disconnection from a stable floodplain has resulted in
increased channel velocities and shear stresses, causing bank erosion and bed incision The
middle portion of UT1 is incised with no floodplain connectivity Additionally, a large overflow
ditch from Crooked Creek has been created adjacent to UT1 This overflow ditch allows for
\ Crooked Creek #2 Restoration Project
Mitigation Plan Page 15

large flow events from Crooked Creek to empty into UT1, causing incision and over - widening to
the downstream portion of this channel. The stream bed exhibits few stabilizing structures and
long runs with few poorly - defined, shallow pools provide low quality in- stream habitat
throughout the entire reach The riparian buffer along most of the upstream section of UT1 is
dominated by invasive vine and shrub species with few mature trees and stabilizing vegetation.
The downstream section of this reach exhibits impacts from cattle access including trampled
banks and little to no understory growth under a well- developed canopy Biological sampling of
this channel indicated a low presence of benthic macroinvertebrates and amphibians. UT1
scored 49 out of a possible 100 points on the USACE Stream Assessment Form and scored 34 5
out of 63 possible points on the DWQ Stream Classification Form, indicating perennial status
(SCPI )
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,
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 DWQ Stream
Classification Form, indicating intermittent status (SCP2) UT2 transitions to a perennial RPW
at the confluence with the open water wetland 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 DWQ Stream Classification
Form, indicating perennial status (SCP3).

Determination is included in Appendix B
42.1 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
UT1 Reach 1 to Crooked Creek has a low width -to -depth ratio and a high entrenchment ratio
with extensive floodplain access The reach has been channelized and straightened, so
Crooked Creek #2 Restoration Project
Mitigation Plan Page 16

sinuosity cannot be used for classification The channel contains sediment with a median
diameter in the very fine gravel fraction
UT1 Reach 2 to Crooked Creek exhibits a moderate width -to -depth ratio and a high
entrenchment ratio with extensive floodplain access. The reach has been channelized and
straightened, so sinuosity cannot be used for classification The channel contains sediment
with a median diameter in the gravel 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.
Tables 5a and 5b summarize the existing conditions parameters for Crooked Creek and UT1
based on geomorphic survey data. Detailed geomorphic surveys were not conducted on UT2
since a lower level of enhancement II is proposed.

Notes
1 The Rosgen classification system is for natural streams These channels have been heavily manipulated by man and
therefore the Rosgen classification system is not applicable
2 Reach 2 is downstream of the confluence with the overflow channel Since further field analysis is required to
determine the hydraulic regime of the overflow channel, estimating the discharge of Reach 2 at this point is not feasible
3 Only the sediment samples from Reach 1 were used since Reach 2 is significantly affected by the overflow channel
*Channel was dry during survey, slope was calculated using the channel's thalweg
4 2 2 Valley Classification
The project reaches are located in a surrounding fluvial landform. Alluvial terraces and
broad floodplains are the predominant depositional features for this valley type. Slightly
entrenched and meandering channels are typically found in this valley type. Active
agricultural operations have altered the valleys for each project reach through tilling,
ditching, and grading. Characteristics of each project stream valley are summarized in Table

4 2 3 Discharge
Multiple methods were used to approximate the bankfull discharge and choose a design
discharge for the UT1 restoration reach Design discharges for the other reaches on the
project site were not developed since enhancement II are proposed Due to the agricultural
and forest land cover within the watershed, discharge estimates were made using methods
intended for rural watersheds. The regional curve relating bankfull discharge to drainage
area for rural watersheds in the Piedmont region of North Carolina (Harman, et al , 1999)
was used to estimate the bankfull discharge for UT1. In addition, the U.S Geological Survey
(USGS) flood frequency equations for rural watersheds in the North Carolina Piedmont
(Weaver, Feaster, and Gotvald, 2009) were used to estimate the 2 -year through 100 -year
peak discharges for UT1. The 1 2 -year and 1.8 -year peak discharges were then extrapolated
from the USGS peak discharge values The 1 2 -year and 1 8 -year peak discharges give a
bracketed approximation of bankfull Historic gauge data were collected from multiple
nearby stream gauges operated by the USGS Two of these gauges with long -term,
continuous records of discharge and relatively small drainage areas were selected to assist
with developing the design discharge (USGS 021246600 Clear Creek at SR3181 near Mint
Hill, NC and USGS 0212467595 Goose Creek at SRI 525 near Indian Trail, NC). These two
gauges passed the homogeneity test (Dalrymple, 1960) indicating that they are located within
a single homogenous region in terms of streamflow characteristics The percent impervious
of the watershed at the Clear Creek gauge is 13% while the percent impervious of the
watershed at the Goose Creek gauge is 11 %. While these percent impervious of each of the
two gauges are higher than the percent impervious of UT1 (3 %), the gauge data can still be
�- used as a tool in developing design discharge. Methods described in Bulletin 17 B
(Interagency Advisory Committee on Water Data, 1982) were used to determine the
discharges associated with the 1.4 -year and 1 8 -year recurrence intervals for these gauges.
The basin ratio method was then used to estimate a bankfull discharge for the restoration
reach based on the bankfull discharge at the Clear Creek and Goose Creek gauges This
method was applied by simply multiplying the ratio of discharge to drainage area of a gauge
to the drainage area of the design reaches. Each of the methods described above was used to
estimate a bankfull discharge or discharge with recurrence interval approximating bankfull
for the UT1 design reach Manning's equation was also used to estimate a bankfull discharge
with the existing cross - section dimensions These estimates were plotted with the regional
curve data to show the range of discharge estimation as shown in Figure 9
A design discharge for the UT1 restoration reach was selected based on the analyses
described above. The design discharge was chosen to be slightly smaller than the bankfull
discharge estimated by the regional curve since frequent flooding and smaller channels are
desirable adjacent to wetland mitigation areas Table 7 summarizes the results of each of the
discharge analyses described in this section

Table 7. Summary of Project Stream Design Discharge Analysis
Crooked Creek #2 Restoration Project
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 floodplams
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 1.6. 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
trees 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.
UT1 to Crooked Creek drains the northern portion of the project area and exhibits effects
from past ditching efforts throughout the upper reach, along the property line Additionally,
a large overflow ditch from Crooked Creek was created adjacent to UTL This overflow ditch
allows for large flow events from Crooked Creek to empty into UT1, causing incision and
over - widening to the downstream portion of this channel A small berm also exists along the
left top of bank from the upstream project limit to its confluence with the Crooked Creek
overflow channel The cross sectional area of UTl changes drastically after the confluence
with the overflow channel, from around 20 square feet (SF) to about 73 SF The stream bed
exhibits few stabilizing structures and long runs with few poorly - defined, shallow pools
provide low quality in- stream habitat throughout the entire reach The riparian buffer along
most of the upstream section of UT1 (Reach 1) is dominated by invasive vine and shrub
species with few mature trees and stabilizing vegetation. The downstream section (Reach 2)
of this reach exhibits impacts from cattle access including trampled banks and little to no
understory growth under a well - developed canopy

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 floodplams
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 1.6. 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
trees 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.
UT1 to Crooked Creek drains the northern portion of the project area and exhibits effects
from past ditching efforts throughout the upper reach, along the property line Additionally,
a large overflow ditch from Crooked Creek was created adjacent to UTL This overflow ditch
allows for large flow events from Crooked Creek to empty into UT1, causing incision and
over - widening to the downstream portion of this channel A small berm also exists along the
left top of bank from the upstream project limit to its confluence with the Crooked Creek
overflow channel The cross sectional area of UTl changes drastically after the confluence
with the overflow channel, from around 20 square feet (SF) to about 73 SF The stream bed
exhibits few stabilizing structures and long runs with few poorly - defined, shallow pools
provide low quality in- stream habitat throughout the entire reach The riparian buffer along
most of the upstream section of UT1 (Reach 1) is dominated by invasive vine and shrub
species with few mature trees and stabilizing vegetation. The downstream section (Reach 2)
of this reach exhibits impacts from cattle access including trampled banks and little to no
understory growth under a well - developed canopy
Crooked Creek #2 Restoration Project
Mitigation Plan Page 22

The bed material of the channels is a distribution of gravel and cobble D50 values range
from 3 1 (very fine gravel) to 43.8 (very coarse gravel) UT1 upstream of the overflow ditch
consists of primarily silt/clay and fine gravels With the exception of UT1's upstream reach,
all of the channels have both gravel and cobble substrate While the coarser material was
predominantly found in the riffles and runs and the finer material in the pools, particles of
both size ranges were found throughout all streambed features.
4 2 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 land cover in the contributing
watershed to Crooked Creek has changed at a fast pace since the early 1970's and continues
to 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
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 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
r the positive features such as the mature hardwood buffer
"J UT1 has historically been straightened Channelization usually includes straightening and
deepening of streams and is one of the mayor causes of channel down - cutting, or incision
(Simon, 1989, Simon and Rmaldi, 2006) This maintenance of a straight -line channel has
steepened the channel such that sediment transport calculations indicate the existing
condition slope is steeper than needed to move the sediment load This indicates that the
channel has the potential to degrade The portion of the channel upstream of the overflow
channel (Reach 1) appears to be actively degrading This section is not extremely vertically
incised, but lacks channel habitat diversity and bank - stabilizing vegetation The portion of
the channel downstream of the overflow channel (Reach 2) appears to be actively degrading
and widening. This section is downcutting to meet the incised grade at Crooked Creek with
continuous and unlimited cattle trampling These disturbances have not allowed the channel
to stabilize itself
Channelization induced channel incision which led directly to over - steepened banks that
subsequently began to fail resulting in channel widening and creation of the current U- shaped
channels Livestock have had access to most of the streams located in the downstream area
for decades which has increased the degree of lateral erosion.
4 2 6 Channel Stability Assessment
The primary cause of Crooked Creek's destabilization is cattle access Bank height ratios
range from 1 1 to 1 6 The removal of cattle access and the addition of woody vegetation for
bank protection will help to protect this reach from further degradation
Crooked Creek #2 Restoration Project
Mitigation Plan Page 23

UT1 is incised, over -wide, and will continue to have stability problems without corrective
action Vertical banks appear to be eroding and the few mature trees at the top of bank are
falling into the creek Bank angles need to be reduced, a stable cross - section should be
constructed, and floodplain access should be provided. Establishment of bank vegetation
will help to stabilize the banks.
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.
42.7 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, Wildlands 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
A HEC -RAS hydraulic model was developed from the survey data to verify the selected
bankfull discharge for UT1 A range of flows from the 1 -year discharge to the 2 -year
discharge was run with the model The resulting stage for each flow was compared to the
bankfull indicator height above water surface elevation estimated during geomorphic
surveys The hydraulic model indicated that a discharge of 10 to 40 cfs corresponds to the
elevation of bankfull indicators observed in the field Based on extrapolation from the USGS
regression equations, the recurrence interval of this flow range is between 1 and 1 8 years
4.2.8 Vegetation Community Types Descriptions
Vegetation habitats within the project area are primarily comprised of open pastures
dominated by various grammoid 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 pensylvanicum), purple deadnettle (Lamium purureum),
perennial ryegrass (Lolium perenne), Nepalese browntop (Microstegium vimineum), and
white clover (Trifolium repense)
Crooked Creek #2 Restoration Project �-
Mitigation Plan Page 24

4 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).
A small portion of site exhibits an abundance of invasive vine and shrub species and includes
the upstream corridor of UT1. Typical vegetation includes sub - canopy species of black
willow (Salix nigra), box elder, red cedar (Juniperus virginiana), and red maple Shrub layer
vegetation includes multi -flora rose (Rosa multiflora), common blackberry (Rubus argutus),
and invasive Chinese privet (Ligustrum sinense) with vine species including green catbriar
(Smilax rotund folia), poison ivy (Toxicodendron radicans), and invasive honeysuckle
(Lonicerajaponica)
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 UT1 (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 palustrine 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 palustrine 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 5/1), 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
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
Crooked Creek #2 Restoration Project
Mitigation Plan Page 25

patterns, an algal mat, water - stained leaves, oxidized rhizospheres, low chroma soils (5YR /
5/1), 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 palustrine 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 (DPI, 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 1) was used to model existing and proposed
groundwater hydrology at the site. DramMod 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 21 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 GWG5 and GWG10 —
on the site (Figure 8). Groundwater gauge 5 represents the wetland creation area and
groundwater gauge 10 represents the wetland restoration area Resulting model output
was used to validate the proposed plan for wetland creation and restoration on site and to
develop a water budget for the site. The modeling procedures are described below.
Crooked Creek #2 Restoration Project ,- -,
Mitigation Plan Page 26

Data Collection
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 April of 2012. 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 8 The models were developed using the conventional drainage water
management option to best simulate the drainage of the site Gauge 5 was installed in
late May 2011 and gauge 10 was installed in February of 2012 Both gauges recorded
groundwater depth once per day with Ecotone water level monitoring gauges through
April 2012
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 2011 and April 2012 were used to calibrate the
models Calibration is an iterative process of making reasonable adjustments to model
inputs, running the models, and comparing the output groundwater depth over time to the
observed gauge data groundwater depth for the same time period until the model's
prediction is acceptable. Plots of calibrated model output compared to observed data are
included in Appendix D.
Proposed Conditions Model Setup
The proposed conditions models for gauges 5 and 10 were developed based on the
calibrated 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 in the wetland creation area of three to twelve inches in most locations One
small high area in the creation zone will require approximately 15 inches of cut Other
construction activities will include removing a system of existing agricultural ditches that
currently drain portions of the site, planting native wetland plants, and roughing the
(- Crooked Creek #2 Restoration Project
Mitigation Plan Page 27

surface soil through disking. These proposed plans were developed to increase the
wetland hydrology in drained hydric soils on site and create wetland hydrology in the
creation zone 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 The proposed conditions
drain spacing accounts for the proposed alignment of UT1. Drain depths were altered
from the existing ditch depth to the proposed depth of UT1 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 will not be lower than the existing ground surface at the gauge
locations, the ground surface elevation were not altered in the proposed conditions
models 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 calibrated 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 minimum percentage of 7.5% of the growing season as
requested by the Interagency Review Team (IRT), the modeling results show that gauges
GWG5 and GWG10 would meet the criteria 66 years and 71 years respectively out of the
76 -year period following implementation of the restoration/creation activities described
above
4.3.2.2 Surface Water Modeling at Restoration Site
No other modeling of surface hydrology, other than the 14EC -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
evaporation of water from the soil or through the transpiration of plants. From the water
Crooked Creek #2 Restoration Project
Mitigation Plan Page 28

1
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 (i.e , ET is greater than runoff and
drainage) For GWG5, the proposed modifications to the site result in little change in the
amount of precipitation that becomes runoff or infiltrates the soil, however the amount of
infiltrated precipitation that is lost through evapotranspiration increases while drainage
decrease However, for GWG10, the amount of precipitation that becomes runoff is
decreased significantly while evapotranspiration is decreased and drainage is increased.
So for GWG5, existing conditions runoff is relatively low but improved wetland
hydrology is provided in the proposed condition by a decrease in subsurface drainage
along with no increase in surface runoff For GWG10, the proposed conditions
hydrology is provided by a significant decrease in water lost through runoff on the site

4 3.3 Sod Characterization
An investigation of the existing soils on the wetland restoration/enhancement site was
performed by Wildlands 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 Wildlands 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 Wildlands
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 (NRCS, 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
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 floodplam 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,
Crooked Creek #2 Restoration Project
Mitigation Plan Page 30 j

channery silty clay loam from 18 to 25 inches, and weathered highly- fractured
metasedimentary rock from 25 to 40 inches
4 3.33 Hydraulic Conductivity
The Chewacla series has a moderately high to high Ksat value ranging from 0 57 to 1.98
in/hr. It is somewhat poorly drained and typically has a water table depth of six to 24
inches The Badin series has a very low to high Ksat value ranging from 0 00 to 1.98
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 Palustrine 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 Consideratlons
4 4 1 Endangered and Threatened Species
The Endangered Species Act (ESA) of 1973, amended (16 U.S C 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).
Wildlands 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 (Lasmigona decorate),
Michaux's sumac (Rhus michauxu), and Schweinitz's sunflower (Helranthus schweinitzii)
are currently listed in Union County (Table 9) The approved Categorical Exclusion

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 32

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 21 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
44.3 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
444 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. UTl to Crooked Creek has not been studied and is not mapped on the FIRM
panel.
The effective hydraulic model for the mapped floodplain will be obtained from the NC
Floodplain Mapping Program. Wildlands 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 Floodplain Mapping Program for approval
- , Crooked Creek #2 Restoration Project
Mitigation Plan Page 33

prior to construction If hydraulic modeling indicates that the 100 -year flood elevation will
not 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 Floodplam Mapping
Program Steep hill slopes should prevent off -site flooding adjacent to the wetland
restoration areas

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 project 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
the criteria described in Table 11

d Receipt of necessary DA permit authorization or written DA approval for projects
where DA permit issuance is not required
6.0.2 Subsequent Credit Releases
All subsequent credit releases must be approved by the DE, in consultation with the IRT,
based on a determination that required performance standards have been achieved For
stream projects a reserve of 15% of a site's total stream credits shall be released after two
bank -full events have occurred, in separate years, provided the channel is stable and all other
performance standards are met In the event that less than two bank -full events occur during
the monitoring period, release of these reserve credits shall be at the discretion of the IRT
As projects approach milestones associated with credit release, the EEP will submit a request
for credit release to the DE along with documentation substantiating achievement of criteria
required for release to occur This documentation will be included with the annual
monitoring report
6.1 Goose Creek Watershed Buffer
The Goose Creek Watershed Plan (GCWP, 2002), developed in September 2002 by the
Goose Creek Watershed Advisory Committee, presents recommendations to protect creeks
from urban Stormwater runoff and to remove Goose Creek from the 303(D) list Among the
recommendations is the protection of riparian buffers The Site Specific Water Quality
Management Plan for the Goose Creek Watershed (SSWQMP, 2009) defines the rules and
conditions by which riparian buffers are protected and mitigated. Buffer restoration and
enhancement requires native hardwood tree species planted at 320 trees per acre, along with
a fertilization plan, conservation easement, and five -year annual survival monitoring. The
proposed riparian planting plan and monitoring plan exceed these requirements Buffer
enhancement credit is awarded at 3 1 mitigation credit ratio while buffer restoration is
awarded at a 1.1 mitigation credit ratio Table 10 lists the total Goose Creek Buffer credits
for this project
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 1 0) The goals were
established to meet EEP'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 in
Section 1 0 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 overarching goals described
Crooked Creek #2 Restoration Project
Mitigation Plan Page 37

above in section 1 0. 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:
• Construct stream channels that will remain relatively stable over time and adequately
transport their sediment loads without significant erosion or aggradation
• Construct stream channels that maintain riffles with coarse bed material and pools with
finer bed material
• 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 stream reaches so that floodplains and wetlands are frequently flooded to
provide energy dissipation, detain and treat flood flows, and create a more natural
hydrologic regime
• Construct fencing to keep livestock out of the streams
• Raise local groundwater table through raising stream beds and 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.

71 Target Stream Types, Wetland Types and Plant Communities
71 1 Target Stream Type(s)
Two reference reaches were identified near the project area and used to support the design of
the project reaches (Figures 10 and 11) 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. Design
parameters for this project were also developed based on the design discharge along with
dimensionless ratio values associated with successful restoration designs of streams in the
North Carolina Piedmont Reference reach data for similar streams were obtained from
existing data sets and used to verify design parameters The reference streams considered
when developing design parameters for this project include Spencer Creek and UT to Lyle
Creek These reference streams were chosen because of similarities to the project streams
including drainage area, valley slope and morphology, bed material, and location within the
Piedmont
7.12 Reference Streams Channel Morphology and Classification
The first reference site ( Spencer Creek) is located in Montgomery County west of Troy with
a drainage area of 0.5 mi . Data from the Spencer Creek reference site were used from the
Big Cedar Creek Restoration Plan by Baker Engineering (2007) and from the NC
Department of Transportation Reference Reach Database Spencer Creek is located in a
mature forested area with 20- to 50- year -old forest growth. Land uses within the watershed
are 98% forested and 2% agricultural fields This reference reach is vertically and
horizontally stable, has moderate pattern with a sinuosity measurement of 1 1, has well -
established pools at outside of channel bends, has several points of aeration in the form of
riffles and woody debris dams and tree roots, and show excellent in- stream habitat This
reference stream classified as an E4 /C4 Wildlands previously visited the reference site to
verify the data presented in the both reports Two riffles were surveyed during the site visit
The surveyed riffles had a width to depth ratio of 7.3 and an entrenchment ratio of 26 3 with
an overall channel slope of 132% The D50 of the two riffles were sampled to be 8 6 and 8.8
mm and classified as fine gravel and medium gravel
The second reference reach investigated for the project, UT to Lyle Creek, is located just
north of Interstate 40 in Catawba County At the downstream limits of this unnamed
tributary, the drainage area is 160 acres (0 25 mil) Land uses within this watershed are
approximately 70% forested and 30% open pasture and active agriculture UT to Lyle Creek
receives drainage from adjacent wooded uplands and is fully connected to the floodplain with
a bank height ratio of 1 0 and an entrenchment ratio over 2 5. The width -to -depth ratio is
31 7 and the overall channel slope is approximately 0 4% UT to Lyle Creek has a sinuosity
of 17. In- stream habitat structures within this reach included short, shallow pools and small
sections of tree roots This channel classifies as a Rosgen C5/6 stream type (1994) The
channel substrate classifies as very coarse sand with a D50 of 0.2 mm Wildlands previously
performed a geomorphic survey on this reference reach
The reference reach data were useful in evaluating the eventual design goal of the project
with the realization that without the mature vegetation observed on the reference reaches, the
Crooked Creek #2 Restoration Project
,5 Mitigation Plan Page 39

extreme dimensionless ratios are not appropriate for a newly- restored stream with little or no
bank and floodplam vegetation All of these reference reaches have width to depth ratios in
the C to E range depending on the particular cross section considered For general
classification purposes, they are on the cusp between E and narrow C streams. There is often
considerable variability of the widths and depths of a stable natural channel — even within a
morphologically similar reach This is very common of smaller Piedmont streams and is
representative of the conditions planned for the Crooked Creek site. Although each of the
reference sites has one or two parameters that are not similar to UTI, they are still valuable
resources. The Spencer Creek reference reach is steeper than UTI, but has a similar D50
While the UT to Lyle Creek reference reach has smaller substrate than UTI, the channel
slope is very similar. Dixon Creek exhibits larger substrate but has a comparable slope and
bankfull discharge as UTI Summaries of geomorphic parameters for the reference reaches
analyzed for this project are included in Table 12

7 1 3 Target Wetland Type(s)
The wetland elements of this project include the following (Figure 12):
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 include
Wetland BB will be plugged in order to restore hydrology to this portion of the floodplairi
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 as well as the proposed rerouting UT1 will raise
the groundwater table to within 12 inches of the ground surface for a significant portion of
the growing season and will achieve hydrology criteria for the agreed upon 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
Crooked Creek #2 Restoration Project
Mitigation Plan Page 41

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 6 6 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 A 3.9 acre area
of non - hydric soils surrounding the ditch will be graded to a lower elevation to create a larger
wetland feature. Most of this area will be cut 3 to 12 inches with one small high area cut 15
inches Minimal grading will also be performed along the perimeter of the ditch in order to
lay back the vertical banks. This entire 4 2 acre area will be disked to increase surface
roughness to better capture rainfall and to improve connection with the water table for
groundwater recharge The entire area of Zone B will be planted with native shrub and tree
species This planted community will also be a Piedmont Bottomland Forest.
714 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 EEP 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
72 Design Parameters
Based on assessments of the watershed and existing channels, the designs have been developed
to correct incision and lack of pattern caused by channelization, 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 restoration and
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 12
7 2 1 Stream Design Parameters
The morphologic design parameters for the restoration reach (Table 13) fall within the ranges
specified for C streams ( Rosgen, 1996) However, the specific values for the design
parameters were selected based on designer experience and judgment and were verified with
morphologic data form reference reach data sets. The width to depth ratio for UT1 will be
approximately 17 The design riffle slopes of the restoration reach range from 0.0045 to
Crooked Creek #2 Restoration Project
Mitigation Plan Page 42

0 0080. UTI will be reconnected with the existing floodplain (Priority 1) The restored
channel will have an entrenchment ratio of greater than 2 2 The sinuosity for the restored
channel will be near 127 Due to the favorable topography and the absence of constraints,
Wildlands proposes a Rosgen Priority 1 restoration approach for UTI completely off -line of
the existing channel. Surveyed topography shows a natural valley exists near the middle of
the site, suggesting that the existing channel was relocated in the past for agricultural reasons
The new channel will achieve the appropriate dimension, pattern, and profile for its
watershed and valley type A short section of Rosgen Priority 2 will be necessary at the end
of UTI in order to tie into Crooked Creek The restored channel will improve in- stream
habitat, reduce bank erosion, and improve water quality
An overflow channel that is fed by Crooked Creek upstream of the project limits flows onto
the project site and connects to UTI before flowing back into Crooked Creek. Extensive
flow records and /or hydraulic modeling would be required to accurately determine the
channel - forming discharge of UTI downstream of its confluence with the intermittent
overflow channel The overflow channel will be re- routed into Crooked Creek separate of
UTI. The overflow connector cross section will be designed based on the dimensions of the
surveyed cross sections collected on UTI downstream of the confluence On -site wetlands
will be restored or enhanced by plugging existing channels to improve wetland hydrology
Enhancement II is proposed for Reach A and B of Crooked Creek as shown in Figure 12
Cattle will be excluded and riparian vegetation will be planted to encourage bank
stabilization
Enhancement II also is proposed for UT2. Banks will be graded, stabilized, and vegetated to
prevent further erosion The project will also include the restoration, creation, and
enhancement of riparian wetland areas adjacent to Crooked Creek, UTI, and UT2.
Geomorphic design parameters have not been developed for Crooked Creek Reach A and B
or UT2 since enhancement II is proposed Geomorphic design parameters have been
developed only for UTI since this channel is where restoration is proposed

722 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
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 19 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 floodplain areas Permanent riparian herbaceous species will be
selected from the species listed in Table 14a and 14b

73 Stream Project and Design Justification
The existing conditions assessment of the project reaches of Crooked Creek, UTI, and UT2
indicate that channelization of the streams and livestock operations have resulted in incision and
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) The riparian buffer along UTI has been removed
completely or is severely degraded Based on assessments of the watershed and existing
channels, designs have been developed to correct incision and lack of pattern caused by
channelization, 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
UTI appears to be degrading This reach is not extremely vertically incised, but lacks channel
habitat diversity and bank - stabilizing vegetation It seems that UTI will eventually progress to
degradation and widening given the condition of the downstream reach of UTI Installing a
channel to the proper dimension, pattern, and profile and planting a native riparian buffer will
restore the habitat function, stabilize the banks, and ultimately have a positive benefit on water
quality.
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 The least invasive treatment option has been selected to ensure long term
stability.
7.4 Data Analysis
7 4 1 Sediment Transport Analysis
Sediment transport analysis is based on data collected by Wildlands during geomorphic and
windshield surveys. A sediment transport analysis is only necessary for UTI since it is the
only proposed restoration reach Neither aggradation nor degradation is a significant concern
for Crooked Creek Reach A and B and UT2 Enhancement II efforts on those reaches are not
expected to change the sediment transport characteristics Since the sediment distribution
and cross sectional area of UTI change significantly downstream of the confluence with the
Crooked Creek #2 Restoration Project
Mitigation Plan Page 47

overflow channel, only the upstream sediment samples and cross section were used in the
analysis (XS6)
741.1 Assessment
A windshield survey of the contributing watershed to UT1 confirmed that it is relatively
stable with no significant source of sediment Most of the watershed is established '
agricultural field crops, with the remainder being woods and farming operations A
review of historical aerial photographs shows that the land use in the watershed has been
agricultural since 1948, with the addition of chicken houses in the upper portion
sometime prior to 1993. The upstream channel seems to be somewhat stable with no
signs of bank erosion Although it lacks a mature riparian buffer, the bank slopes are
well vegetated and have relatively flat side slopes There are no plans of future
development within the watershed according to local planning documents
The supply limited watershed coincides with the sediment regime observed in the on -site
UT1 reach The on -site reach contains no mid - channel bars or other sediment
depositional areas that would indicate a capacity problem. UT1 becomes more incised
downstream and seems to be actively degrading before the confluence with the overflow
channel. There is no indication that the deterioration of this channel has been driven by
recent watershed disturbances Sediment samples collected from UT1 have a D50 of
3.1 mm and are somewhat homogeneous within the very fine gravel to fine gravel range
(Appendix B) UT1 exhibits no problem transporting the limited sediment supplied by its
watershed or its bed material Based on the low sediment load of the watershed and the
very fine to fine gravel substrate in the existing channel a threshold channel design
approach and competency analysis is valid for UT1; capacity is not a concern This
design approach is based on the concept that the morphology of the channels is not
sensitive to sediment supply and channel migration and changes in slopes are not
expected or desired
74.1.2 Modeling and Design
Threshold channel design uses standard equations to calculate the critical dimensionless
shear stress needed to move the bed material and the depth and slope combination needed
to produce that stress The equations are:
(1) Tc, = 0.0834(d5o /ds50 )-0872
(2) T,, = ds /(ys *Di)
(3) d = (T,, *ys *Di) /S
where Tc, is critical dimensionless shear stress, d50 is median diameter of pavement
material, ds50 is median diameter of subpavement material, ys is specific weight of
sediment, Di is the largest diameter of subpavement material, d is mean bankfull depth of
channel, and S is the water surface slope at bankfull stage The very fine to fine gravel
particle sizes collected on UT1 do not fall within the appropriate range for the empirical
equations to be applicable
The bankfull shear stress for UT1 was calculated using the sediment competence
equation,
Crooked Creek #2 Restoration Project
Mitigation Plan Page 48

i =yRS
where i is the bankfull shear stress, y is the specific weight of water, R is the hydraulic
radius, and S is the average water surface slope. The bankfull shear stress for the
proposed channel will be approximately 0.13 lbs /ft2 Using the modified Shield's
relationship of critical shear stress to the largest movable particle indicates that the
calculated bankfull shear stress will move a 20 to 40 mm particle. The largest
subpavement particle size collected was 16 mm, which indicates that the design channel
will have the shear stress necessary to move the sediment particles found in the channel
The channel may have a small amount of excess shear stress. In- stream structures and
constructed riffles will be used to protect against degradation
A HEC -RAS model was developed to verify the bankfull shear stresses for the proposed
conditions Proposed riffle and pool typical sections were used to produce a more
accurate representation of the shear stresses within the channel Table 16 summarizes the
riffle and pool shear stresses calculated in HEC -RAS. As expected, riffle shear stresses
are greater than pool shear stresses In most cases, the calculated shear stress is at or
greater than the shear stress required to move the largest particle according the modified
Shield's relationship The overall channel shear stress median value of 0.12 Ibs /ft2
reinforces the bankfull shear stress as predicted by the sediment competence equation
(0.13 lbs /ft2).
Table 16. Summary of Shear Stress in Design
Crooked Creek #2 Restoration Proiect
The existing and proposed channels were analyzed using the hydraulic design module
within HEC -RAS to further validate the design slope and typical section with respect to
sediment transport The existing channel cross section, slope, and sediment distribution
collected during the geomorphic survey was computed with the stable channel design
option (Copeland method) For the proposed channel, the typical riffle section and
proposed slope were computed with the same sediment distribution used for the existing
channel The resulting stability curves compare base width of the channel to the average
channel slope (Appendix B) Plotting the existing base width and slope data point and
the proposed base width and slope data point indicate that the proposed design channel
will be more stable than the existing channel.

Based on competency analysis results (Table 17), the proposed UTl channel typical
sections and slope will adequately transport the sediment found in the channel Even
though the calculated shear stresses are greater than the modified Shield's critical shear
stress, the values are still within a normal range. The design specifies constructed riffles,
grade control sills, J -hook vanes and other grade control structures to prevent bed scour
and incision Constructed riffle material will consist of 4 to 8 inch native substrate from
Crooked Creek mixed with 3 to 6 inch quarry stone The results of the sediment transport
analysis discussed above indicate that this material size will be large enough to provide
grade control and withstand excess shear stress Using material larger than that which the
critical shear stress can transport coincides with the threshold channel design approach
The threshold channel is designed for minimal or nonexistent boundary migration To
accomplish this, the allowable shear stress calculated from X should be greater than the
design shear stress Native material will be harvested from a side channel along Crooked
Creek during the enhancement II operations The side channel will be filled in but
contains excellent native material These features, along with vegetated 3.1 side slopes
and reconnection with the floodplain, will help to prevent incision at bankfull and larger
storm events while still allowing the proper transport of sediment

9.1 Streams
9 2 1 Dimension
In order to monitor the channel dimension, a total of four permanent cross - sections will be
installed along UT1. Cross - sections will be located at representative riffle and pool sections
on each monitored reach. Each cross - section will be permanently marked with pins to
Crooked Creek #2 Restoration Project --

establish its location. For channels with bankfull of greater than 3 feet, bank pins will also be
installed on the outside bend of each surveyed pool cross - section in at least three locations
(one in the upper third of the pool, one at the permanent cross - section, and one in the lower
third of the pool). Bank pins will be monitored by measuring exposed rebar and maintaining
pins flush to the bank to capture bank erosion Cross - section and bank pin surveys will be
conducted in monitoring years one, two, three, five, and seven and compared with data from
previous years
9 1 2 Pattern and Profile
Longitudinal profile surveys will not be conducted during the seven year monitoring period
unless other indicators during the annual monitoring indicate a trend toward vertical and
lateral instability If a longitudinal profile is deemed necessary, monitoring will follow
standards as described in the EEP Monitoring Requirements and Performance Standards for
Stream and /or Wetland Mitigation (11/7/2011) and the 2003 USACE and NCDWQ Stream
Mitigation Guidance for the necessary reaches
9 1 3 Photo Documentation
Approximately 34 permanent photographs will be established within the project stream and
wetland areas after construction Photographs will be taken once a year to visually document
stability for seven years following construction Permanent markers will be established so
that the same locations and view directions on the site are monitored each year Photographs
will be used to monitor restoration and enhancement of stream and wetland areas as well as
- vegetation plots. The photographer will make every effort to maintain the same area in each
photo over time. Reference photos will also be taken for each of the vegetation plots and
cross- sections. The representative digital photo(s) will be taken on the same day surveys are
conducted.
91.4 Substrate
A reach -wide pebble count will be conducted for classification purposes on the restoration
reach (UTI) Pebble counts will also be conducted at permanent riffle cross - sections. The
pebble counts will be conducted annually for seven years following construction and
compared with data from previous years
9 1 5 Bankfull Events
Bankfull events will be documented using a crest gauge, photographs, and visual assessments
such as debris lines Three crest gauges will be installed; one on Crooked Creek, one on
UT1, and the other gage on UT2. The crest gauges will be installed onsite in a riffle cross -
section of the channels at a central site location The gauges will be checked at each site visit
to determine if a bankfull event has occurred during the seven year monitoring period.
Photographs will be used to document the occurrence of debris lines and sediment
deposition.
9.1 141sual Assessments
Visual assessments will be performed along all stream and wetland areas on a bi- annual basis
during the seven year monitoring period. Problem areas will be noted such as channel instability
" Crooked Creek #2 Restoration Project
Mitigation Plan Page 53

(i a lateral and /or vertical instability, in- stream structure failure /instability and /or piping,
headcuts), vegetated buffer health (i.e low stem density, vegetation mortality, invasive species
or encroachment), beaver activity, livestock access, etc. Areas of concern will be mapped and
photographed accompanied by a written description in the annual report Problem areas with be
re- evaluated during each subsequent visual assessment Should remedial actions be required,
recommendations will be provided in the annual monitoring report
9.2 Vegetation
A total of 32 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 based on 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
1st and September 31St 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 Wet /ands
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 EEP Mitigation Plan Template (version 2 1, 09/01/2011), the EEP
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 stream restoration
reach (UT1) of the project will be assigned specific performance criteria components for stream
morphology, hydrology, and vegetation 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
101.1 Dimension
Riffle cross - sections on the restoration reaches should be stable and should show little
change in bankfull area, maximum depth ratio, and width -to -depth ratio Per EEP guidance,
bank height ratios shall not exceed 1.2 and entrenchment ratios shall be at least 2 2 for
restored channels to be considered stable. All riffle cross - sections should fall within the
parameters defined for channels of the appropriate Rosgen stream type. If any changes do
occur, these changes will be evaluated to assess whether the stream channel is showing signs
of instability. Indicators of instability include a vertically incising thalweg or eroding channel
banks Changes in the channel that indicate a movement toward stability or enhanced habitat
include a decrease in the width -to -depth ratio in meandering channels or an increase in pool
depth Remedial action would not be taken if channel changes indicate a movement toward
stability
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
Crooked Creek #2 Restoration Project
Mitigation Plan Page 55

1013 Photo Documentation
Photographs should illustrate the site's vegetation and morphological stability on an annual
basis Cross - section photos should demonstrate no excessive erosion or degradation of the
banks Longitudinal photos should 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
10.1.4 Substrate
Substrate materials in the restoration reaches should indicate a progression towards or the
maintenance of coarser materials in the riffle features and smaller particles in the pool
features
1015 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 reaches at the end of the required monitoring
period (year seven). The interim measure of vegetative success for the site will be the survival of
at least 320 planted stems per acre at the end of the third monitoring year and at least 260 stems
per acre at the end of the fifth year of monitoring Planted vegetation must average 10 feet in
height in each plot at the end of the seventh year of monitoring. If this performance standard is
met by year five and stem density is trending towards success (i e., no less than 260 five year old
stems /acre), monitoring of vegetation on the site may be terminated provided written approval is
provided by the USACE in consultation with the NC Interagency Review Team The extent of
invasive species coverage will also be monitored and controlled as necessary throughout the
required monitoring period (year five or 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 7.5 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 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
Crooked Creek #2 Restoration Project
Mitigation Plan Page 56

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
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

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

Boxes checked below shall be supported by completing the appropriate sections in Section III below
2 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)
3 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 I and Section III.D.i. 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 III.B below

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 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 i 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 offsrte 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 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 TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the 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
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented

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 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
I 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 111.111 for
the tributary, Section III.B.2 for any onsite wetlands, and Section 111 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

For each wetland, specify the following

Summarize overall biological, chemical and physical functions being performed
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and /or biological integrity of a TNW
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e g between a
tributary and its adjacent wetland or between a tributary and the TNW) Similarly, the fact an adjacent wetland Iles 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 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

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 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

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 TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream 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.
