Response to NCDMS Mitigation Plan Comments
This memo documents NCDMS's initial Draft Mitigation Plan review comments (in italics) received from
Matthew Reid's letter dated 12/15/2020,the project team's responses, and where the revisions have
been included in the final Mitigation Plan.
Mitigation Plan Comments:
General:
• Recent IRT comments have requested providers ensure that when measuring the centerline of
the channel for crediting purposes that only one channel is measured at the confluence. UT1A
and UT1B are calculated to the center of UT1. UT1 is calculated to the center of Oak Hill Creek.
These reach measurements should end at or near the top of bank of the receiving stream and
should not be calculated to the centerline. Please revise report, tables and plans asnecessary.
Response: Stream channel centerline lengths have been recalculated per the requested protocol
for UT1A, UT1B, and UT1.The report,tables, plans, and corresponding digital GIS layer has been
updated accordingly.
• The IRT has requested recently that a figure noting the different planting zones be included in
the mitigation plan. Please consider adding this figure to the Figures section of the appendix
and reference in Section 6.9.
Response: Figure 12 (Proposed Planting Zone Map) has been added to the appendix and is
referenced in Section 6.9.
Title Page:
• Please include the DWR project number if available.
• Please also provide the date of issuance with the RFP#: RFP#:16-007704(Issued:9/6/2018)

Response:The title has been updated to include the DWR project number and the date of
issuance of the RFP.
Table of Contents:
• Section 10.0 Determination of Credits should be 11.0, and Adaptive Management Plan should
be 10.0.
Response:The Table of Contents has been updated accordingly.
Introduction:
• Please use the total asset amounts as shown on Table 31. Currently it is 4,643.985 SMUs and
8.034 WMUs, but this will be different after first comment is addressed.
Response:The Introduction has been updated with the total revised asset amounts reflected in
Table 32.
Table 2:
• Please include the stream thermal regime(warm)in the summary table. DMS acknowledges
that this is a variance from the current table template.
Response:Table 2 has been updated accordingly.
UT1A:
• DMS and DEQ stewardship recommend a minimum 15-foot setback from structures and the
conservation easement.If possible,please increase the setback in this area to prevent potential
problems in the future.
Response: At its narrowest(measuring perpendicular from the building corners),the clearance
from the building to the easement is 10 feet and 13 feet, respectively. At its greatest (at the
easement corner)the clearance is greater than 20 feet. Overall,this was a very tight spot. We
originally anticipated that the building would be demolished as part of the project; however,the
owner changed their mind and wanted to continue to use it for its remaining life which is limited.
As such, we have attempted to maximize the stream buffer but still provide adequate room to
access the side and back of the building. We believe the existing easement is functionally
adequate and that little stands to be gained by undertaking the difficult process of revising the
easement.
3.3.2 Existing Wetlands:
• This section indicates that the PJD package that was submitted in August 2020 and is located
in Appendix 2. The submitted PJD package did not make it into the draft mit plan. Please be
sure to include in the final submittal. In the future, please go ahead and include the package
that was submitted in the draft report even if it is still under review.
Response:The finial PJD was issued on 12-7-2020 and can be found in Appendix 2. Wildlands will
include submitted PJD packages under review going forward.
3.5 Site Constraints to Functional Uplift:
2

• The description of the ford crossing regarding cattle access does not provide confidence that
cattle will be excluded permanently. The description reads that the landowner does not intend
to use it for cattle in the "short term". Please revise to make clear that cattle will not have
access in the future except to cross or something similar. Will there be fence and gates provided
to prevent future cattle access?
Response:The description has been revised to clarify that there is no intent at this time to use
the crossing for livestock. It further clarifies that if at some future time the crossing is used for
this purpose that it shall be modified to provide fencing and gates to exclude livestock from the
crossing.
6.2 Reference Streams:
• Text indicates that geomorphic parameters for reference reaches are summarized in Appendix
4. This information was not included in the draft report appendix. Please verify and/or update
for final.
Response: A reference reach parameter summary table has now been added for inclusion to
Appendix 4.
6.5 Sediment Transport Analysis:
• What is the source of the coarser material to be used in riffles? Will it be harvested locally?
Response: It is anticipated that some or all of the coarser material in riffles will be imported from
a quarried or alternative offsite source—no viable on-site source of such material has been
identified. Material in the old channel may be appropriate to fulfill a portion of the need.
• The plan indicates bar formation as a factor contributing to the existing channel instability.
The proposed conditions indicate reach segments where the d84 will not be mobilized at the
bankfull flow. Will these segments become areas of bar formation with stabilityconcerns?
Response: Bar formation is presently a concern because of the present instability in channel
width and floodplain discontinuities resulting in depositional patterns that favor channel
evolution as the channel attempts to resolve incision and widening trends. The proposed
geometry starts at a place of stability and will correspondingly result in hydraulic conditions and
depositional patterns that promote deposition in locations that will contribute to increased
stability rather than detract from it.
Table 16:
• The wetland mitigation activities do not include the proposed overburden or sidecast cut.
Please add these proposed actions to the table to be consistent with the plan.
Response:The removal of berm material was added to mitigation activities in Table 16 for
Wetland Rehabilitation, Wetland Re-establishment, and Wetland Creation areas.
6.6 Stream Design Implementation:
• How much of OHC-R1 will be P2? By the way this section is written, it leaves the reader
uncertain if the P2 will be limited to tie-ins or whether it will be more extensive.
3

Response: Language was added to Section 6.6 and 6.6.1 indicating that the Priority 2 sections of
stream only account for a few hundred feet of proposed channel on the Site; and in particular on
Oak Hill Creek Reach 1 the Priority 2 area is limited to approximately the first 100 feet of stream.
• Please briefly describe how WE/will construct the Priority 2 sections. Will topsoil be
stockpiled?Minimum bench width and side slopes? Since establishment of vegetative cover
and vigor can be a challenge on Priority 2 banks and benches, please include a discussion on
how the soil restoration will be addressed during construction and reference potential
adaptive management.
Response: Wildlands grading specifications typically require stockpiling the top 3 inches of soil in
areas of the project where grading cuts exceed the topsoil horizon of the soil.This soil is then
reapplied to the cut area before permanent seeding or plantings are applied.This will be
required during construction at the Oak Hill Dairy Site and will be a special point of emphasis on
Priority 2 floodplain benches. Minimum bench width varies by stream size, with a minimum
bench width of 12 feet for larger streams (Oak Hill Creek and UT1) and a 3-foot bench width on
small streams (UT1A). Side slopes will be 3:1 minimum. Permanent riparian seed will be re-
applied to areas that did not establish vegetation during the initial seeding until adequate
coverage is achieved.
• While no credit is being asked for UT2 and UT3, there is significant work being done to tie
these two streams into the Oak Hill Creek. Please briefly mention this work as well as the
additional culvert/pipe replacements in the driveway vicinity that will be routed to Oak Hill
Creek within the conservation easement.
Response: An additional section was added to the mitigation plan (section 6.6.9) that details the work
on UT2 and UT3.
6.7.5 Stream Design Implementation:
• The plan sheets indicate that there are areas requiring more than 12"of grading. The
wetland cross sections show that these areas are limited to berms and side cast areas.Areas
requiring more than 12"of grading are typically credited at a lower ratio. Can WE/quantify
the total area requiring more than 12"of grading and/or add additional discussion in the
plan for clarification?
Response: Discussion of proposed wetland areas with greater than 12 inches of cut was added to
Section 6.7.5 and illustrated in an additional figure (Figure 10). Areas of greater than 12 inches
cut in re-establishment and rehabilitation areas accounted for about 16.8%of the total are
proposed for these restoration types.Table A below summarizes the percent of each wetland
restoration type that is graded more than 12 inches for re-establishment and rehabilitation and
creation.
Table A: Wetland Grading Depth (greater than 12 inches cut)
Wetland Restoration Type %Graded area with greater than 12
inches cut
Re-establishment and Rehabilitation 16.81%
Creation 31.82%
4

• Suggest providing more justification for the proposed credit ratio of 1:1 wetland rehabilitation
since these are currently jurisdictional and no expansion of wetland area in these areas will be
achieved.
Response: Discussion of justification for wetland rehabilitation crediting was added to section
6.7.5.
6.8 Storm Water BMPs:
• Are the two proposed BMPs designed to be maintenance free.Does WEI anticipate any long
term maintenance issues or risks associated with the BMPs?
Response:While the two proposed BMPS may not be totally maintenance free,they were
designed to minimize maintenance needs as much as feasible. Several paragraphs discussing
BMP risks and maintenance considerations were added to Section 6.8.
• The BMPs will provide a benefit to the project;however, they are very large and there is no
detail provided with the draft report. Will a detail be provided with the revised draft?
Response:Yes, a BMP detail has now been included in the revised planset.
6.9 Vegetation, Planting Plan and Land Management:
• Please include bamboo(Phyllostachys a urea)in the invasive species discussion.
Response: Bamboo is now included in the invasive species discussion.
• Does WEI plan on treating fescue and other undesirable pasture grasses prior to or during
construction?The/RT has recommended early treatment in the past based on observations of
fescue impeding planted vegetation establishment and vigor.
Response:Wildlands will use a combination of mechanical and chemical applications to remove
fescue prior to and during Site construction. Populations of undesirable pasture grasses exist
throughout the project corridor. Mechanical removal of remaining fescue populations will take
place during construction if necessary.
• The Planting Plan as presented in Section 4.1 of Appendix 12 does not comport with the
community types identified in Section 6.9. Please review and revise as necessary.
Response: Many factors go into the development for each project planting plan. Community type
being one of the major factors. Wildlands must also consider the availability and cost of nursery
stock and seeds. To avoid a significant number of alternates, Wildlands will swap a more suitable
plant species for a community of widely available species.
6.10 Project Risk Management:
• Please also describe the site specific conservation easement marking and type of fencing that
will be utilized to restrict livestock from encroachment.
5

Response: Conservation easements shall be marked in accordance with DMS requirements as
outlined in items#4 and #5 of the Survey and Boundary Marking Requirements section in the
DMS guidance document titled: Full Delivery Requirement for Completion of Survey for
Conservation Easements.
Livestock will be excluded. It is anticipated that fencing is necessary for this purpose and that the
type of fencing will either be barbed wire or electric. Smooth wire electric is being
recommended for use at crossings to reduce the potential for damage from out of bank flows
and debris.
• Will the fords be subject to livestock use?Will there be end gates?
Response:The landowner does not intend to use the ford for livestock crossing at this time. If they
install fencing to allow for this use in the future, the fencing shall have end gates to serve to keep
livestock out of the creek when the crossing is not in use.
• Consider adding discussion regarding hydrologic trespass potential to any area outside of the
conservation easement.
Response: Since the submittal of the draft plan, Wildlands has completed hydraulic modeling and
has revised Section 4.2 to reflect the finding of this modeling for FEMA permitting and to address
concerns of backing up base flow in project streams.
7.0 Performance Standards/8.0 Monitoring Plan:
• Please consider utilizing the most recent DMS templates and guidance for the as-built survey,
record drawings, and MYO-MY7 reports. These templates and guidance were updated in
October 2020 and are available on the DMS website.
Response: Wildland will evaluate the most recent DMS templates and guidance and determine if
it can be used for the As-built, record drawings, and monitoring period for this project.
8.0 Monitoring Plan and Figure 10:
• Per recent IRT guidance, please be sure to include photo points at culverts and crossings in the
monitoring plan.
Response: Photo points have now been included at culverts and crossings. Please see updated
Table 30 and Figure 11.
Figure 2:
• Please include location of the DWR stream form assessments on the existing conditions map.
This is of greater importance for UT1B where the form ostensibly sums to 21 points.
Response:The location of stream classification points from the DWR stream assessment forms is
now included on the existing conditions map (Figure 2). Steve Kichefski and Krysta Stygar, of the
Army Corps of Engineers, did not raise concerns about UT1B during the PJD field verification walk
on December 7th, 2020. UT1B exhibited flow throughout both,the intermittent and perennial
reaches, in conjunction with moderate to strong iron oxidizing bacteria.The low score in the
6

intermittent section can be attributed to weak flow and low slope;the weak flow and low slope
provides minimal stream power for sediment transport in the intermittent section.
Appendix 4:
• Please denote the point used as the LTOB for XS2.XS2 BHR looks like an overestimate.
Response: A note has been added to the cross section plot for XS2 (OHC Reach 1) in Appendix 4
that denotes the low top of bank and elevation used in calculating a bank height ratio of 2.4. For
XS2,the low top of bank was located along the right bank and not the left bank as the comment
suggests.There is a flood bench measuring approximately 14 feet wide along the left side of the
channel but it, like most other flood bench features observed in other cross sections, was not
considered the actual low top of bank for consistency in measuring bank height ratios throughout
the project.
Appendix 9:
• A copy of the Conservation Easement Template is not included in the Appendices. Please
remove this statement or revise for final submission.
Response:The statement has been removed from the Site Protection Instrument in Appendix 9.
Preliminary Design Plans:
• Sheet 0.1:Please use the Raleigh shipping address for the Owner:
NCDEQ—NC DMS
217 West Jones St,Suite 3000A
Raleigh, NC 27603
Response:The design plans have been updated accordingly.
• Please include culvert and ford details in revised draft. Members of the IRT would appreciate
reviewing this information.
Response: Culvert and ford details are now included in the design plans.
• BMPs: Please include any additional information, detail or specificity for BMPs in final
submittal.
Response:Additional language has been added to the Mitigation Plan discussing BMP maintenance
and design (see Section 6.8). In addition, a preliminary BMP detail was added to the planset (See
detail 3, SHT 5.3)
• Planting Plan: Please consider including the wetland indicator status on planting tables. Also,
based on recent comments, the IRT would like to see the planting list included within the
Mitigation Plan.
Response: Wildlands updated the planting list to include wetland indicator status on planting
tables.The updated planting list is included in Table 28 in the Mitigation Plan.

1.0 Introduction
The Oak Hill Dairy Mitigation Site (Site) is in Gaston County approximately 2 miles northeast of
Cherryville and 7 miles southwest of Lincolnton (Figure 1).The Site is within the NC Division of
Mitigation Services (DMS) Lower Indian Creek targeted local watershed Hydrologic Unit Code (HUC)
03050102050010 and the NC Division of Water Resources (DWR) Subbasin 03-08-35, and will provide
stream and wetland credits in the Catawba 03 Expanded Service Area.The project proposes to restore,
enhance, and preserve impaired streams. Wetland re-establishment is proposed to restore a stream-
wetland complex, and best management practices (BMPs) are proposed at points of concentrated
agricultural runoff.The existing streams are presented in Figure 2.The work proposed on the Site will
provide 4,611.641 stream credits and 8.055 riparian wetland credits and will be protected in perpetuity
by a 20.4-acre conservation easement.

Project Name Oak Hill Dairy Mitigation Site
County Gaston

2.0 Basin Characterization and Site Selection
The Site is in the Catawba 03 Expanded Service Area,which is composed of a mix of forested land (47%),
agricultural land (30%), urban areas (18%). Forested land is predominantly located within the upper
portion of the basin,while the agricultural land and urban areas are more concentrated to the central
and lower portions of the basin, respectively.The major developed areas include Hickory, Newton,
Lincolnton, Gastonia, and Belmont, and the main roadways consist of US-321, 1-40, and 1-85. Indian
Creek,the receiving waters for the Site which is shown in Figure 1, is 303(d) listed as impaired for
exceeding the narrative criteria to protect aquatic life in fresh water, which means the water is not
suitable for aquatic life propagation and maintenance of biological integrity. Multiple conservation and
watershed planning documents outline water quality goals and objectives for the broader Catawba River
basin and the smaller Indian Creek basin as summarized below:
• The 2007 (amended 2013) Catawba River Basin Restoration Priorities (RBRP) lists restoring
impaired waters by removing conditions causing sediment impairments and improving
management to reduce direct cattle impacts to streams as goals for the watershed. Indian Creek
is discussed specifically in the RBRP with the priority to improve agricultural non-point source
pollution on this rural creek.
• The 2015 North Carolina Wildlife Resource Commission's (NCWRC)Wildlife Action Plan (WAP)
notes that sedimentation, loss of riparian woody vegetation,water withdrawals, channelization
and/or relocation, point source pollution, and nutrient loading are the primary causes of stream
habitat degradation in the Catawba River basin.
• The 2008-2010 Indian Creek and Howards Creek Local Watershed Plan (LWP) documents
identified major functional stressors in the watershed as channelization and stream dredging;
incised channels and unstable stream banks; degraded and deforested riparian buffers;
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 1 January 14, 2021

degraded wetlands; livestock access to riparian buffers and streams; and fecal coliform and
nutrient inputs.
o The Site is located in subwatershed 1-14, as defined in the Indian Creek and Howards
Creek LWP. Subwatershed 1-14 is specifically prioritized in the document as being a good
candidate for agricultural BMPs.
o The Site was identified in the Indian Creek and Howards Creek LWP Project Atlas as R-
104 (Oak Hill Creek and UT1). R-104 was ranked in the highest priority category(Tier 1)
for a potential stream restoration project in the Indian Creek watershed with the
recommendation of bank stabilization, channel realignment and reconnection with the
floodplain, and riparian buffer restoration.
The Site was selected due to its ability to support local watershed objectives and goals by excluding
livestock, creating stable stream banks, restoring a forest in agriculturally maintained buffer areas, and
implementing agricultural BMPs.These actions will reduce fecal, nutrient, and sediment inputs to
project streams, and ultimately to Indian Creek, South Fork Catawba River, and the Catawba River, as
well as reconnect instream and terrestrial habitats on the Site. Restoration of the Site is directly in line
with recommended management strategies outlined in the LWP and RBRP.
3.0 Baseline and Existing Conditions
3.1 Watershed Conditions
The Site watershed (Table 2 and Figure 3) is situated on the partially developed, northeast edge of
Cherryville in Gaston County, within the Piedmont.The Piedmont 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 Site topography and relief are typical for the region, as illustrated in Figure 4. Generally,
valleys onsite are unconfined and alluvial, and valley slopes tend to flatten as elevation decreases.
Site streams are classified as Class C waters and are protected for secondary recreation,fishing and fish
consumption,wildlife, aquatic life, and agriculture.
The Site watershed includes the subwatersheds of Oak Hill Creek, UT1, UT1B and UT1A. Land use within
the overall watershed includes a mix of forest, agriculture, and some development, including single-
family homes and commercial use along NC 150 (Lincolnton Highway). While the land use of the Site
watershed is predominantly rural, Oak Hill Creek drains a large portion of the town of Cherryville and
may be considered an urban channel with an estimated 11.6%impervious cover in its 1.7-square mile
watershed (Figure 3).
The Oak Hill Creek subwatershed is the largest contributing drainage area to the Site,the majority of
which lies offsite to the south.The southern and eastern headwaters of this subwatershed are bound by
a combination of Tot Delinger Road, Lincolnton Highway(NC 150), single-family neighborhoods and a
large commercial trucking facility, all of which comprise the largest proportion of impervious area
contributing to Oak Hill Creek.The central,flatter portion of the Oak Hill Creek subwatershed is
occupied by the Cherryville Golf and Country Club which has minimal riparian buffers and has expanded
within the last decade with the clearing of additional forest land.
The subwatershed of UT1 is 0.5 square miles where it enters the site and is bound to the west by Tot
Delinger Road and to the east by Roy Eaker Road which are generally bordered by low density
residential land use.The subwatershed contains a larger proportion of forest land compared to Oak Hill
Creek. Most of the riparian corridor along UT1 that drains to the Site contains a forested buffer.The

forested buffer narrows within the downstream half of the subwatershed along the left floodplain,
including within the project Site, where active cattle pastures are situated.
Subwatersheds UT1A and UT1B are small drainage areas that flow into UT1. UT1A drains active cattle
pasture and feeding area on the Site and UT1B drains residential and forested land as well as a grass
field.
The Oak Hill Creek watershed is located just outside of the city limits of Cherryville but within its
extraterritorial jurisdictional (ETJ) boundary. According to the Gaston County 2035 Comprehensive Land
Use Plan, some expansion of existing commercial and residential land uses is expected in the future, but
the area is likely to be balanced by the preservation of agricultural lands and open space, and thus
continue to serve more as a "rural development pocket" (Gaston County Planning& Development
Services, 2016).The land within these watersheds is zoned for Highway Business, Manufactured Home
Parks, Manufacturing, and Residential Limited.
A review of historic aerials (Appendix 1)from 1950 to 2016 shows that onsite streams have remained in
the same landscape position for the past 60 years.The agricultural management of the land has also
remained consistent with the following exceptions:
• The dairy waste lagoon that exists today on the project parcel (just south of the larger pond)
was constructed between 2006 and 2009.
• The larger pond in the northeast corner of the Site (that is routed under Robert Road, and joins
Oak Hill Creek offsite)was constructed between 1964 and 1973.
• Most of the larger structures on the project parcels were constructed between 1973 and 1976,
but the two large feed barns located to the south and west of the waste lagoon were built in the
last 15 years.

3.2 Landscape Characteristics
The Site is in the Cat Square terrane of the Piedmont physiographic province which is composed of
deformed metamorphic rocks that have been intruded by younger granitic rocks.The underlying
geology of the Site is mapped as Cherryville Granite (Mc)from the Mississippian Period (330 to 360
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 3 January 14, 2021

million years in age).The formation is described as massive to weakly foliated; containing pegmatites
that are lithium bearing on the eastern side of the formation. Site streams are predominantly gravel-bed
streams, although a bimodal distribution reflects the large quantity of fines coming from both upstream
and within the Site. No exposed bedrock was observed within the Site.
The soils in ecoregion 45b, Southern Outer Piedmont, consist of mostly quaternary to tertiary aged
sandy clay, clay, micaceous clay, and sandy saprolites with rock outcrops and joint block boulders.The
predominant Site floodplain soils on site are described in Table 3 below and depicted in Figure 5. Large
portions of active cattle pasture bordering the Site are mapped as Wedowee and Pacolet Sandy Loam
soils which are highly susceptible to erosion in bare areas and could be indicative of the high sediment
load observed within the channel.

In general,the cattle pastures on the Site are dominated by pasture grasses such as fescue and millet
species with scattered trees along the top of bank. Row crop fields have previously been planted with
corn. Mature canopy species within these areas are primarily black walnut(Juglans nigra),tulip poplar
(Liriodendron tulipifera), river birch (Betula nigra), willow oak(Quercus phellos), sweet gum
(Liquidambar styraciflua), and sycamore (Platanus occidentalis). Shrub species are primarily Chinese
privet (Ligustrum sinense), multiflora rose (Rosa multiflora), and thickets of blackberry(Rubus spp.) In
addition to pasture grasses,the ground cover in these areas include some river cane (Arundinaria
gigantea), horsenettle (Solanum carolinense), beefsteak(Perilla frutescens), English ivy(Hedera helix),
and Japanese honeysuckle (Lonicera japonica).
3.3 Project Resources
3.3.1 Existing Streams
In May 2020, Wildlands investigated on-site jurisdictional waters of the United States (US)within the
proposed project area.The Site contains six unnamed tributaries (UT's)that have been assigned the
following names for the project: Oak Hill Creek, UT1, UT1A, and UT1B, UT2, and UT3. All tributaries
were deemed perennial except for UT1B which was deemed intermittent until just upstream of its
confluence with UT1 where it transitions to perennial flow.
Oak Hill Creek is the mainstem drainage of the Site; it originates off site and flows north and then east
through the project area. UT1 enters the Site through a culvert under Roy Eaker Road and flows east to
join Oak Hill Creek. UT1A originates off site and flows southeast to join UT1. UT1B is a small channel that
enters the Site through a culvert under Roy Eaker Road and flows east to join UT1. UT2 and UT3 are
small tributaries that drain into Oak Hill Creek from the right floodplain in the downstream third of the
project; mitigation credit is not being pursued for these two tributaries but both are proposed to be
extended in length to tie into the realigned mainstem channel of Oak Hill Creek.Jurisdictional stream
features are shown on Figure 2 and supporting documentation is provided in Appendices 2 and 3.
Geomorphic surveys were conducted on Site streams to characterize their existing condition. Existing
streams and cross section locations are illustrated in Figure 2. NCDWR stream assessment forms and
NCSAM forms are in Appendix 3 and reach specific cross sections and geomorphic summaries are
provided in Appendix 4.

Oak Hill Creek Reach 2
Oak Hill Creek Reach 2 begins downstream of the sanitary sewer easement where a riprap/concrete nick
point is present;the reach extends downstream to the confluence with UT1.As discussed in Section 6.7,
the reach was ditched prior to 1950 based on visual interpretation of aerial photography(Appendix 1).
Reach 2 is actively widening as a result of severely eroding outside bends. Reach 2 has a high bank
height ratio and relative confinement except for the building point and side channel bars. Both banks
lack deep-rooted vegetation and point bars are infested with kudzu. Closer to the confluence, Chinese
privet is dominant along the banks. Pockets of other invasive species, including tree of heaven and
Japanese knotweed, were also observed. Mixed with the privet, some mature vegetation is present in a
14, Oak Hill Dairy Mitigation Site Draft Mitigation Plan

narrow buffer along the tops of banks. Large woody debris is sparse along Reach 2. Riffles and pools are
present, but of poor quality due to embeddedness with
fines. Oak Hill Creek Reach 2
A linear wetland (Wetland B) is located along the left r
valley toe of Oak Hill Creek Reach 2. Based on soil , ' '
borings and review of aerial photography(1984, 1993, �h .:,
Appendix 1),this wetland appears to be the remnants of , 4...." t 4
a ditch that used to drain the proposed wetland re- ,, `44 ° _
establishment areas and which likely extended the
length of the valley down to Robert Road.The linear -5
feature drains into UT1 Reach 2. In the same vicinity, a
wood tile drain empties into Oak Hill Creek at the n E'
tortuous outside bend.

Oak Hill Creek Reach 3
Oak Hill Creek Reach 3 begins at the confluence of UT1 and extends downstream along the right side of
the valley to the UT3 confluence. Historical aerial imagery suggests Reach 3 was ditched prior to 1950
(Appendix 1). In some areas where trees and privet have held the banks together,the banks are
wooded. In other areas, and beyond the banks,there is a corn field on the left floodplain and fallow
fields on the right.
The instream habitat and overall channel stability continues to degrade downstream, with more fine
sediment in the bed of the channel,frequent areas of bank erosion and incision, and the presence of
mid-channel bars. Some undercut banks and leaf packs provide instream habitat. Privet continues to be
a dominant bank species,with tree of heaven and morning glory(lpomoea indica) noted as other
invasive species of concern.The dairy's large waste lagoon is situated atop the left valley of Oak Hill
Creek Reach 3 and, if overtopped, would drain through a ditch network that routes runoff in a manner
that bypasses the left floodplain in Reaches 3 and 4 (Figure 2).This ditch also collects local drainage
from upland fields along the entire left valley.The adjacent landowner's driveway parallels the creek
toward the downstream reach limits, and concrete slabs have been used to armor the banks to protect
the driveway.

Oak Hill Creek Reach 4
OHC Reach 4 begins at the confluence of UT3 and terminates downstream at a culvert beneath Robert
Road. Reach 4 has severe bank erosion in some areas and, although was classified as a Rosgen E5-type
channel due to active widening resulting in an entrenchment ratio greater than 2.2, it is incised with a
bank height ratio of 2.6.The entire length of Reach 4 immediately abuts a gravel driveway on the right
top of bank with only a narrow row of trees, and portions of the channel bordering the driveway have
been armored with stone or concrete to halt on-going bank erosion. Erosion from debris jams and the
incised channel condition is common. In many of the locations within the reach that have deep-rooted
vegetation,the vegetation is being undercut and lacks sufficient root depth to prevent long term
widening. Reach 4 is similar to OHC Reach 3 with respect to drainage area, channel dimension, pattern,
and profile but classified out as a sand bed channel due to the impact of upstream bank erosion
throughout the Site.Throughout its length,the stream centerline of Reach 4 is roughly coincident with
the Site property boundary.

UT1 Reach 1 enters the Site from a perched culvert under Roy Eaker Road. An overhead electric line and
power pole are present on the left top of bank at the top of the reach.The stream drops 9 inches over
the culvert outlet and is incised with eroding areas downstream of the culvert.Alternating lateral bars
are forming within the incised channel, and varied habitats are present although they are embedded
with fines from bank erosion. Very little woody debris is present in the reach. Although cattle are

UT1 Reach 2 begins at the confluence of UT1B and r .,
terminates at its confluence with Oak Hill Creek. As (It ".t,*.
noted in the Hydric Soils Report (Appendix 5), aerial .` , t1
photography indicates that UT1 was relocated from •
the middle/right side of the valley to the left valley
toe between 1950-1956. Based on the topography and soil characteristics, spoils may have been side
cast into the historic floodplain creating an unnatural high spot through the middle of the valley and
leaving remnant wetland pockets. Presently,the upstream half of the reach generally flows along the
toe of the right valley wall while the downstream half of the reach flows along the toe of the left valley
wall. UT1 Reach 2 is bordered by five small wetland areas (Wetlands B, C, D, E, and F), many of these
coincident with linear drainage features thought to have been created to draw water off historically wet
areas of the floodplain. Downstream of UT1A,there is a draw on the left floodplain that contributes
runoff from the cattle feedlot into UT1. Several cattle sloughs or wallow areas were observed along the
tops of both banks throughout the entire length of UT1 Reach 1.This is consistent with landowner
verbal confirmation that cattle are allowed access seasonally to flash graze areas in order to manage
kudzu and other vegetation.

The stream was classified as a Rosgen G4-type channel based on its degree of incision. Privet along the
banks throughout much of the reach appears to have slowed the rate of channel widening over time;
however,the channel is vertically unstable with several advancing headcuts in the upper half of the
reach and laterally unstable where it has previously undermined privet and other bank vegetation.
While the valley is broad throughout the reach corridor, channel pattern is minimal. Meander pools
should be present but are rare, and pool spacing is tight. Riffles and pools typically occur in locations
inconsistent with stable planform geometry.
Habitat along UT1 consists of riffles with some overhanging roots and pools. Riffles are often embedded
with fines and large woody debris is scarce. Riparian vegetation consists of a single line of mature
vegetation at the top of bank, with maintained crop fields to the left and fallow fields and black walnuts
(Juglans nigra)to the right.The understory and banks are dominated by privet and the right valley wall
and floodplain edge has a severe infestation of English ivy(Hedera helix).
UT1A
The Site was extended upstream from the location originally specified in the DMS technical proposal and
initial NCIRT site walk and currently encompasses the UT1A jurisdictional stream boundary which is in a
bamboo thicket(Phyllostachys aurea). At this location, UT1A drops approximately two feet at an existing
knickpoint. As it emerges from the thicket downstream, it bisects a small wetland area (Wetland J), likely
a result of erosion and cattle wallowing immediately below the existing fence line. An existing residence
on the right floodplain is occupied and must remain—the easement has been set 10 feet off the
residence. UT1A flows within the primary feedlot for the dairy and
is utilized by cattle for drinking;the adjacent areas are impacted by UT1A near Upstream Limits
gi
the concentrated activity. Except for a few stand-alone trees, UT1A f�
is devoid of riparian vegetation and a shaded canopy.The stream is 1
incised and overly wide, and the bed and banks are severely
trampled with toe and valley slope erosion. In the bamboo section,
some bedform and habitat is present, but these give way to silted ,.- I II
and braided runs with no bedform throughout the remainder of the \ _--' �'�
reach. Fine sediments are embedding any underlying bedform
material from consistent erosion and sedimentation of the adjacent 4 �
upland areas. At the lower limits of the reach, UT1A flows through .4(4, a `
a marshy, herbaceous area influenced by debris and sediment 4 ` ! �
trapped by the existing fence. If,

Wildlands delineated potential wetland waters of the United States within and immediately adjacent to
the proposed project easement (assessment area) using the USACE Routine On-Site Determination
method presented in the 1987 Corps of Engineers delineation manual and the subsequent Regional
Supplement for the Eastern Mountain and Piedmont Region.The Preliminary Jurisdictional
Determination (PJD)was issued on December 7t". See Appendix 2 for the approved PJD, existing wetland
data is summarized in Table 12.
A total of 7 existing wetland features (Wetlands A, B, C, D, F,J, and K)were documented within the
assessment area (appendix 2). On-site wetland features exhibit indicators of wetland hydrology,
hydrophytic vegetation, and hydric soils. Indicators of wetland hydrology observed in existing wetlands
include aquatic fauna, drainage patterns, surface soil cracks, sparsely vegetated concave surface,
stunted or stressed plants, high water table, water-stained leaves, crayfish burrows, saturation,
geomorphic position, FAC-neutral test, sediment deposits, and surface water. Dominant hydrophytic
vegetation species within wetlands include sugarberry (Celtis laevigata), American elm (Ulmus
americana),jewelweed (Impatiens capensis), arrowhead (Sagittaria latifolia), and jointleaf rush (Juncus
articulatus). Soils within on-site wetlands exhibit one of the following hydric soil indicators: depleted
matrix, redox dark surface, and piedmont floodplain soils.
Existing wetlands were evaluated using the North Carolina Wetland Assessment Method (NCWAM),
which evaluates field conditions relative to reference condition to generate function ratings for specific
wetland types. Using the NCWAM dichotomous key and best professional judgement, existing wetlands
were classified based on the reference wetland type if the area was not disturbed. On-site wetlands
were all classified as Bottomland Hardwood Forest or Headwater Forests. On-site wetlands scored as
low to medium functioning systems when compared to reference conditions because of impairments to
two of the three primary functions (hydrology,water quality, and habitat). Water quality and habitat
functions generally received low scores due to cattle grazing, lack of native vegetative communities, and
poor connectivity to other natural areas. NCWAM field assessment forms and the rating calculator
outputs are included in Appendix 3.

3.4 Overall Functional Uplift Potential
The primary physical stressors on site are incision and entrenchment from historic channelization
coupled with historic and on-going agricultural operations that have drained the site and maintained
narrow or non-existent riparian buffers.These stressors led to low NCSAM scores for most project
stream reaches and low NCWAM scores for project wetlands. Without intervention, Oak Hill Creek and
its tributaries will continue to widen, which will further diminish riparian wetland hydrology. Ultimately,
functional uplift for this Site is linked to improvement in and maintenance of hydrologic connectivity
between streams and riparian wetlands. Additionally, establishing a riparian buffer will protect and
enhance this connectivity. Functional uplift for the site will be achieved through the following:
• Restoring degraded stream channels to reduce erosion and reconnecting streams to their
historic floodplains to restore hydrologic connectivity to riparian wetlands;
• Reducing bank erosion and associated pollutants;
• Planting riparian buffers to shade streams,filter upland runoff, stabilize streambanks with deep-
rooted vegetation, and promote woody debris in system;
• Cattle exclusion;
• Establishing BMP's to provide additional treatment of upland runoff; and
• Protecting the site with a conservation easement.
These project components are described in Section 5 in terms of goals, objectives, and outcomes for the
project and in greater detail in Section 6 as the project site mitigation work plan.
3.5 Site Constraints to Functional Uplift
The following potential Site constraints have been identified and will be addressed as part of this
project.
Due to the tie in elevations and degree of incision onsite, some Priority 2 restoration will be necessary
along portions of UT1 and Oak Hill Creek in transitioning to Priority 1 restoration. Establishing vegetation
on Priority Level 2 stream restoration can be a challenge. Wildlands has prepared a Vegetation and
Planting Plan (Section 6.9)to address this potential constraint. Priority Level 2 restoration may have a
14, Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 15 January 14,2021

limited floodplain on some projects. As described in Section 6.6 Design Implementation, Wildlands will
construct floodplains that are at least 4 times bankfull width and have a slope that is flatter than 5:1.
The Site is currently in active row crop and cattle operation. Care was taken to minimize the number of
stream crossings to those that are necessary for the landowners to maintain their farming operations in
a sustainable manner.Two internal easement crossings are proposed at the Site to maintain landowner
access and use of the adjoining property, and to accommodate an existing sanitary sewer line easement
(20-feet in width)that intersects Oak Hill Creek at the juncture of Reach 1 and 2. At this time, livestock
will be excluded from the proposed ford crossing since the landowner does not intend to use it and its
adjacent areas for this purpose in the short term.The UT1 crossing will be fenced and gated based on
the current intent to use this crossing for livestock rotation post-construction.The crossings are
summarized and numbered below in Table 13 and depicted on Figure 9.All crossings will be designed to
reduce barriers to sediment transport, promote aquatic organism passage, and increase the long-term
stability of the crossings.
Table 13:Summary of Site Easement Crossings and Breaks
No. Width(ft) Location Internal or External Crossing Type
1 50 Oak Hill Creek Reach 1/2 Internal Ford
2 30 UT1 Reach 2 Internal Culvert crossing
There are two structures in the right floodplain of UT1A—a small, occupied house near the upstream
project boundary and an old barn approximately halfway down the reach.The landowner has agreed to
demolish the old barn as part of the project.The easement has been narrowed in the vicinity of the
house.
Utilities within the project area include an existing sanitary sewer that crosses Oak Hill Creek Reach 1 at
its reach break with and overhead utilities along Roy Eaker Road and Robert Road. Internal easement
crossing 1 has been aligned to encompass the sanitary sewer easement.The overhead utility line along
Roy Eaker Road that extends across UT1 Reach 1 is no longer in service and will be removed from the
easement.The conservation easement boundary has been set to exclude the overhead utility on Robert
Road.
Two BMPs are proposed for the Site to intercept and treat storm runoff from the dairy feedlot bordering
UT1A and UT1 Reach 1, and the dairy waste lagoon that short circuits the existing floodplain and drains
directly into Oak Hill Creek.Treated runoff from these two proposed BMPs will outlet into restored
wetland areas and a vegetated floodplain buffer to provide additional attenuation and potential
pollutant load filtering benefits before entering the stream channel. More details pertaining to the
proposed BMPs can be found in Section 6.8.
The entire easement area can be accessed for construction, monitoring, and long-term stewardship
from Robert Road and Roy Eaker Road.

4.1 Biological and Cultural Resources
A Categorical Exclusion for the Site was approved on August 20, 2019.This document included
investigation into the presence of threatened and endangered species on Site protected under the
Endangered Species Act of 1973, as well as any historical resources protected under the National
Historic Preservation Act of 1966.The biological conclusion for the Site, per the Categorical Exclusion
research and response by US Fish and Wildlife Service, is that"the action agency determines that this
project may affect the Northern Long-Eared Bat(NLEB), but that any resulting incidental take of the
NLEB is not prohibited by the finial 4(d) rule."The conclusion for cultural resources per the Categorical
Exclusion research and response by the State Historic Preservation Office is that they are aware of"no
historic resources which would be affected by this project."The signed Categorical Exclusion checklist
and summary are provided in Appendix 6. As stated on the Northern Long-Eared Bat 4(d) Rule
Streamlined Consultation Form provided in the Categorical Exclusion, approximately 1.24 acres of trees
will be cleared during the construction of the project. A complete copy of the Categorical Exclusion
document, including additional information and regulatory communications, is available upon request.
4.2 FEMA Floodplain Compliance and Hydrologic Trespass
The Site is represented on the Gaston County Flood Maps 3710269100K and 3710269000J. All four
project stream reaches of Oak Hill Creek are mapped in a Zone AE Special Flood Hazard Area (SFHA) and
the downstream 400 LF of UT1 Reach 2 is included in the backwater of Oak Hill Creek's mapped
floodplain (Figure 6). UT1, UT1A and UT1B do not have designated SFHAs. Effective hydraulic modeling
for Oak Hill Creek has been obtained from the NC Floodplain Mapping Program. Based on modeling of
the existing and proposed conditions, a Conditional Letter of Map Revision (CLOMR) is anticipated to
address minor rises during extreme flood events.The rises anticipated under these large flows is on the
order of 1-3" with no impact to structures.Wildlands and the County will notify the two affected
landowners through the CLOMR Property Owner Notification process and through Wildlands' own
outreach, as deemed appropriate. Upstream of Oak Hill Creek Reach 1, a rise of 1-3" has been modeled
for the proposed case under the 100-year base flood.This is a naturalized and wooded area with no
developed land impacted. On the right floodplain of Oak Hill Creek in Reaches 3 and 4,the increase in
base flood elevation has been modeled as 0.01'. In this same area along Reaches 3 and 4, Wildlands has
coordinated the installation of new culverts on UT2 and UT3 to address the poor condition of existing
pipes and to simultaneously raise the new pipes in order to prevent excessive backwater of baseflow
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 17 January 14,2021

onto the adjacent landowner. Sufficient existing gradient exists in this area to accomplish the required
grade adjustments and Wildlands has coordinated these activities with the landowner and will obtain a
temporary easement to make these adjustments to UT2& 3. UT1 Reach 1 will be tied into an existing
headcut at the culvert outlet but will not back up water above the elevation of the existing culvert at
Roy Eaker Road. UT1A raises the stream up to an existing knick point but this is contained within the
proposed easement. A LOMR will be completed after construction using as-built survey data.
4.3 401/404
Jurisdictional waters will be impacted with realignment of the stream channel, structure installation and
bank,floodplain and wetland grading. Wetlands on the Site that are within the conservation easement
and outside of the limits of disturbance will be flagged during construction to prevent unintended
impacts.This will be denoted in the final construction plans.The Pre-Construction Notification, including
this data,will be submitted to the NCIRT with the Final Mitigation Plan.
5.0 Mitigation Site Goals and Objectives
The project will improve stream and wetland functions through stream restoration, conversion of
agricultural fields into riparian buffer, and restoring wetlands within the broad floodplains of Oak Hill
Creek and UT1. Project goals are desired project outcomes and are verifiable through measurement
and/or visual assessment. Objectives are activities that will result in the accomplishment of goals.The
project will be monitored after construction to evaluate performance as described in Section 8 of this
report.The project goals and related objectives are described in Table 15.

6.0 Design Approach and Mitigation Work Plan
This Section presents the proposed collective design approach for streams,wetlands, BMPs, and
planting, as well as considerations for land and project risk management for this Site.
The design approach was developed to meet the goals and objectives described in Section 5 which were
formulated based on the potential for uplift described in Section 3.4.The design is also intended to
provide the expected outcomes in Section 5,though these are not tied to performance criteria.
The design focus is the reconnection of streams to their historic floodplains to raise the groundwater
table on the Site and contribute more frequent overbank flow to site floodplain and wetland resources.
Restoration of site hydrology will be further supported by filling agricultural drainage swales and
removing drainage tiles.The floodplains and wetlands will be planted with native herbaceous;tree and
14, Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 19 January 14,2021

shrub species and invasive species will be treated. Instream structures will be constructed in the
channels to help maintain stable channel morphology, improve aquatic habitat, and enhance channel
bedform. Cattle will be excluded from the Site, eliminating wallow areas within the streams and
wetlands. Proposed stormwater BMPs will treat upland runoff entering the Site from areas used for
feeding and grazing of cattle.The entire project area will be protected in perpetuity by a conservation
easement.Table 16 summarizes the stressors of each project reach and the applicable mitigation
activities expected to address those stressors.

6.1 Stream Design Approach Overview
A combination of analog, empirical and analytical approaches for stream restoration design were
employed. Reference reaches were identified to serve as an acceptable range for design parameters.
Channels were sized based on design discharge hydrologic analysis and empirical approaches including
applying regional curve equations. Designs were then verified and/or modified based on a sediment
transport analysis.These design approaches have been used on many successful stream restoration
projects and are appropriate for the goals and objectives for this Site.
6.2 Reference Streams
Reference streams provide geomorphic parameters of a stable system, which can be used to inform
design of stable channels of similar stream types in similar landscapes and watersheds.Ten reference
reaches were identified for this Site(Figure 7) and used to support the design of Oak Hill Creek and its
tributaries.These reference reaches were chosen because of their similarities to the Site streams
including drainage area,valley slope, morphology, and bed material. All selected reference reaches are
located in the North Carolina Piedmont physiographic province where the Site is, except for Boyd
Branch, which is located in the Blue Ridge or mountain province. Boyd Branch was included as a
reference reach for Oak Hill Creek Reach 1 due similarities in drainage area,valley type, width, and slope
between the two streams. Geomorphic parameters for these reference reaches are summarized in
Oak Hill Dairy Mitigation Site Draft Mitigation Plan

6.3 Design Discharge Analysis
Multiple methods were used to estimate bankfull discharges for restoration reaches including regional
curve data (Harman et al. 1999 and Walker, unpublished), a regional flood frequency analysis using U.S.
Geological Survey(USGS) gage sties, and reference reach data.The methods were compared, and a
design discharge was selected based on the results of the different methods. Slightly larger design
discharges relative to drainage areas were established for the mainstem project reaches (Oak Hill Creek
Reaches 1—4)to drive designs of slightly larger channels (by width)for these reaches to the extent of
impervious area or urban influence on storm runoff within the headwaters of the Oak Hill Creek
subwatershed. Results of each method and the final design discharges are shown in Table 18 and
illustrated in Figure 8.

6.5 Sediment Transport Analysis
A qualitative assessment of sediment supply and sources in the project watershed was performed based
on visual inspection and review of historic aerial photos.The Oak Hill Creek and UT1 watersheds have
not changed considerably in recent decades. Redevelopment or future residential expansion around
Cherryville may increase development in both watersheds, particularly UT1 which is less developed.
The Oak Hill Creek watershed has a large portion of its area developed, most notably a large industrial
complex with high impervious cover at its headwaters and a golf course in the middle of the watershed.
There are several small to medium sized ponds on tributary reaches to the mainstem, mostly associated
with the golf course. Between 2011—2017,the golf course was expanded to the west and aerial photos
indicate stream buffer removal as well as some degree of upland erosion.The rest of the watershed is
residential and the main future impacts would be from infill or limited additional residential
development.
UT1 is largely forested on the right bank and the left bank is forested in the upper half of the watershed
but agricultural in the lower half, immediately upstream of the project.
Observed deposition on the Site indicates that both Oak Hill Creek and UT1 deliver fine and coarse
sediment load into the Site. Depositional patterns within the Site are primarily in areas with active
widening through outside or undercut bank erosion. In areas that have redeveloped a narrow bottom
width and depositional benches, streams have coarser bed sediments and coarse sediment is visible on
depositional features. No signs of reachwide or channel aggradation are present within the project area,
even in areas that have widened considerably.
The proposed stream restoration is maintaining bankfull sediment capacity by spreading out the vertical
drop over perched upstream culverts, sewer crossings and knick points in restoration reaches
throughout the length of the project.This is counteracting the typical approach of flattening reach
slopes at the top of projects to transition to Priority 1 restoration. As a result,the slopes of the proposed
channels are similar to those of the existing channels.
Restored streambanks are being sloped at a gentle 3 or 3.5:1 slope in order to allow for adjustment of
channel sediment transport efficiency to the incoming flow and sediment load. In addition, proposed
wetlands have been set back off the stream channel to allow for natural levy formation as a second
natural response and adjustment to sediment loading.
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 27 January 14,2021

In the reaches with the finest sediment gradations, on-site sediment sources are being reduced and the
slopes were increased which will help move fine sediment. To maintain high quality pools, channel
constricting and grade drop features will be utilized in the project. Grade drop features will serve to hold
the base channel elevation and sized and designed to prevent downcutting.
Through meander bend construction, a secondary result of the design is re-establishment of 3-
dimensional vectors in pools that will help maintain pool depths during intermittent high flows.
A competence analysis was performed to analyze the ability of the proposed streams to transport the
sizes of sediment supplied to them.The results of the competence analysis for bankfull flow conditions
are shown in Table 26.The competence analysis on these reaches indicates that the reaches will be able
to transport the d50 to d84 sediment sizes supplied to them by their watersheds in most cases. In cases
where the largest particles can be mobilized, an emphasis was placed on ensuring that adequate grade
control is incorporated into the design.The shear stresses for the 10-year and 50-year events were also
calculated and will be used to incorporate low mobility material into riffles.

The existing d50 in UT1 Reaches 1 and 2 is approximately 20-30 mm.The 50-year flow has a shear stress
of 0.8 lb/sq ft and is capable of moving 60-130 mm particle (2.5 to 5 inches).To promote riffle grade
control stability, riffles in UT1 will be supplemented with particle sizes consistent with a weighted mix of
NCDOT Class A/B mix(2 to 12 inches)to target a d84 at the upper movable particle range.
The existing d50 in Oak Hill Creek ranges from 20-35 mm. Reach 1 has the highest d50, potentially
related to the high input of fine sediment within the project Site reducing the d50 further downstream.
In Reaches 1 and 2,the 50-year flow has a shear stress of 0.8-1.8 lb/sq ft and is capable of moving 60-
230 mm particle (2.5 to 9 inches).To promote riffle grade control stability, riffles in Oak Hill Creek Reach
1 will be supplemented with particle sizes consistent with a weighted mix of NCDOT Class A/B mix(2 to
12 inches)to target a d84 at the upper movable particle range. In Reaches 3 and 4,the 50-year flow has
a shear stress of 1.0-1.6 lb/sq ft, and therefore a similar mix will be incorporated.
The existing d50 in UT1A is sand/silt. UT1A will be constructed with new bed material since the existing
bed material has been buried and smothered due to trampling.The 50-year flow has a shear stress of
3.2-3.4 lb/sq ft and is capable of moving 260-370 mm particle (10 to 15 inches).To promote riffle grade
control stability, riffles and grade control structures in UT1A will be supplemented with large cobble and
small to medium size boulders to provide a low mobility bed.

6.6 Stream Design Implementation
The proposed Site includes a combination of stream restoration, enhancement, and preservation
activities as well as wetland restoration and creation activities detailed in Section 6.7. Project stream
reaches proposed for restoration and enhancement are currently impacted by riparian management,
past and/or present cattle access, bank erosion, and incision. Activities have been selected to provide
the highest degree of ecological uplift to the system. Figure 9 provides an overview of the proposed
mitigation activities on the Site.
The majority of the project reaches are proposed for Priority 1 restoration. Priority 2 sections of channel
will be constructed where needed to transition grade from off-site tie-in to proposed elevations, avoid
hydrologic trespass, and maintain minimum channel slopes. Priority 2 sections of channel only account
for a few hundred feet of proposed stream at the Site. Restoration reaches have been designed to
create stable,functional stream channels based on reference reach parameters, design discharge
analysis, and sediment transport analysis. Dimension, pattern, and profile have been designed for all
restoration reaches to provide a cross-sectional area sized for frequent overbank flows, a stable bed
with variable bedforms, and well-vegetated bank slopes. Improved vertical and lateral stability will
reduce stream channel erosion. Diverse bedforms will be established using in-stream structures
appropriate for the geomorphic settings.These structures will provide grade control to prevent incision
and serve as habitat features. Pools will have varied depths to increase habitat diversity and mimic
natural streams.
In-stream structures for all reaches will include constructed rock riffles, rock sills, log sills, log or rock j-
hooks, log vanes, brush toe, geolifts, bank roughening and cover logs. Constructed riffles will be built
from excavated on-site rock when possible. Quarry stone may be used if an on-site source cannot be
found. Constructed riffles will incorporate woody material and logs, which will provide varied pore
spaces within the riffles and benefit hyporheic exchange processes and habitat formation.The diverse
range of constructed riffle types will provide grade control, diversity of habitat, and will create varied
flow vectors. Log and rock j-hooks will deflect flow vectors away from banks while adding to habitat
diversity. Log and rock sills will be used to allow for small grade drops across pools. At select outer
meander bends,the channel banks will be constructed with brush toe revetments to reduce erosion
potential, encourage pool maintenance, and provide varied pool habitat. Similarly, cover logs will also be
used in some meander bends to provide pool habitat variability and stream bank stability. Sod harvested
on-site and/or coir fiber matting will be used to provide bank protection.
6.6.1 OHC Reach 1
Enhancement I is proposed for Oak Hill Creek Reach 1 and includes the following: bank grading on both
banks to reestablish a stable planform geometry and dimension, widespread benching of outer meander
banks, and channel structure installation in riffles and bends to adjust channel alignment and protect
outer meanders against an urban flow regime and high sediment load.The work in the reach will include
subtle but nearly continuous channel realignment, profile manipulation, and structure installation.The
left floodplain will also be lowered and benched to increase floodplain activation frequency in order to
enhance adjacent riparian wetlands. A mature woody riparian buffer will be established along the left
floodplain, and invasive species will be removed along the reach.The Priority 2 area of Oak Hill Creek
Reach 1 is limited to approximately the first 100 feet of the reach where the design ties to the existing
stream bed.
A 50-foot wide permanent ford crossing is proposed at the downstream limits of Reach 1 in an internal
easement break that includes both the sanitary sewer crossing and the ford.The bed of the channel and
the banks will be hardened at the ford to produce a firm base for passage of farm vehicles. Grade
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 29 January 14,2021

control will be incorporated to the downstream limits of the ford to hold grade in the crossing. Cattle
will be excluded from Reach 1.
6.6.2 OHC Reach 2
Oak Hill Creek Reach 2 is proposed for a combination of Priority 1 and 2 restoration to reestablish
appropriate channel dimension, pattern and profile. Existing channel grade will be raised subtly in Reach
1 and more significantly at the existing knick point at the beginning of Reach 2 where the concrete-
encased sanitary sewer crossing is holding grade. Raising Reach 2 will support proposed wetland
approaches. Visible drainage tiles in the left bank will be followed upgradient and removed to further
this end.
6.6.3 OHC Reach 3
Oak Hill Creek Reach 3 is being realigned away from the valley wall out into the middle of the valley with
appropriate dimension, pattern and profile as a Priority 1 floodplain restoration approach. Reach 3
starts at the confluence with UT1 and has a flat broad floodplain.The Priority 1 approach will help
reconnect Oak Hill Creek with its historic floodplain and restore hydrology to existing and relic wetlands.
BMP 2 is being proposed on the left edge of the floodplain to treat runoff from the adjacent fields and
uplands, including the waste lagoon area as described in Section 6.8.
6.6.4 OHC Reach 4
Oak Hill Creek Reach 4 will transition from the Priority 1 approach used upstream down to the existing
elevation of the Robert Road culvert. A Priority 2 floodplain will be excavated to facilitate the tie-in.
6.6.5 UT1 Reach 1
UT1 will be raised starting the perched culvert outlet at the upstream limits.This Priority 1/2 approach
with floodplain excavation will be used in Reach 1 to transition to a Priority 1 approach in downstream
reaches. Restoration will improve aquatic organism passage by correcting the perched culvert elevation
at the upstream end of UT1 and raising the stream will enhance hydrology in existing and proposed
creation wetlands at the downstream limits of the reach. Restoration will also provide additional
bedform habitat and introduce large woody debris into UT1. Construction of a bankfull channel within
this reach will increase sediment transport efficiency over the existing overwide channel bottom with
inner berm formation.The overhead electric line and power pole on the left top of bank at the top of
the reach and will be permanently removed.
6.6.6 UT1 Reach 2
UT1 Reach 2 will start as a Priority 1/2 floodplain approach but rapidly transition to a Priority 1
approach.The channel will be moved off the edge of the valley wall and meandered with an appropriate
pattern, dimension and profile through the middle of the valley. BMP 1 will be installed in the left
floodplain near the top of Reach 2 to provide volume storage and treatment for drainage from the
concentrated feedlot.The cattle present in the left floodplain of this reach which have had intermittent
access to the reach for flash grazing,will be excluded from the easement.The high area noted in the
existing conditions and Hydric Soils Report(Appendix 5) will be graded down to the prevailing elevation
of the historic floodplain. In the downstream 1/3 of the reach, an internal culvert crossing will be
installed. At the crossing,the entire right floodplain will be left at grade to allow for flood flows to pass
down the floodplain thereby relieving the culvert from carrying high flows.
6.6.7 UT1A
Restoration of UT1A will begin at the jurisdictional boundary where the headcut will be stabilized and
brought up to grade for a Priority 1 restoration. Wildlands has extended the proposed easement from
the original proposal to encompass the entire jurisdictional limits of UT1A and to physically remove and
perform follow-up treatment to address the existing bamboo thicket. Priority 1 restoration of this
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 30 January 14,2021

steeper headwater tributary will result in a valley that has an entrenchment ratio exceeding typical B-
type streams. An Eb stream type is proposed for this hybrid step-pool approach with some meandering
pattern. An existing occupied residence on the right bank must remain and the easement has been
narrowed around the structure. Cattle will be entirely excluded from the easement along this stream
and the streambed will be dredged to remove built up cow manure that forms the majority of the
existing stream bed. Restoration will provide bedform and habitat and introduce large woody debris to
UT1A, all of which are absent from the existing channel. BMP 1 is proposed on the left floodplain at the
end of the reach where it confluences with UT1.This BMP will include a diversion berm within the left
floodplain easement of UT1A to capture additional upland flow from the cattle feeding area and route it
into BMP 1.
6.6.8 UT1B
UT1B is a stable stream with low banks and will be preserved in its existing location.This stream will be
treated for invasive vegetation as the adjacent area is overgrown with kudzu. A narrow right floodplain
is being preserved consistent with the proposal easement and greater than the minimum 15' easement
required for crediting.The left buffer will be planted with riparian species and the right buffer will be
supplemented with native plantings as needed to complement the existing row of trees.
6.6.9 UT2 and UT3
Due to the proposed changes in the alignment and profile of Oak Hill Creek, the alignments of UT2 and
UT3 would need to be extended and profiles raised in order to continue positive flow to Oak Hill Creek.
For both streams,the existing culverts terminated near the existing toe of bank of Oak Hill Creek.
The 36-inch corrugated metal pipe (CMP) culvert at UT2 was in poor condition and will be removed and
replaced with a 36-inch High-Density Polyethylene pipe(HDPE)with a downstream invert that is 1.7 feet
above the existing invert.
The 30-inch Reinforced Concrete Pipe (RCP) culvert at UT3 was found to be in usable condition, but
undersized, especially in regards to aquatic organism passage considerations.The existing culvert will be
reused as a flood relief culvert and a new 36-inch HDPE pipe will be the primary culvert.The new design
will raise the culvert 2.7 feet above the existing downstream invert.The adjacent landowner's driveway
will be modified with new grading to obtain the needed cover over the proposed pipes.
From these proposed downstream inverts, UT2 and UT3 were designed to flow over low slopes (0.5
percent) until their respective confluences with Oak Hill Creek. A major design concern for these small
tributaries was instability during flooding events associated with Oak Hill Creek. The constructed parts
of these streams will be heavily planted with livestakes and seeded with riparian vegetation to mitigate
this risk. Additional transplants from onsite will be preferentially placed in the floodplain immediately
upstream of these tributaries. Woody debris will also be mixed in among the heavily planted areas to
roughen the floodplain and slow flood waters.
6.7 Wetland Design Approach Overview
The Site includes riparian riverine headwater seep, pocket, and floodplain wetlands that will be re-
established and rehabilitated. Proposed wetland restoration and creation areas are adversely impacted
by agricultural ditching, historic channel manipulation, channel downcutting, manmade subsurface
drainage, cultivation for row crops, and cattle impacts.The proposed approach will include multiple
activities to restore site hydrology and vegetation.
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 31 January 14,2021

This project includes the re-establishment,
Area Proposed for Wetland Restoration
rehabilitation, and creation of 9.5-acres of historically
altered wetland-riparian complexes on the floodplains
of Oak Hill Creek and UT1. Both streams will be
constructed through the proposed wetland
restoration areas with a priority 1 restoration
approach that will raise the water table elevation and
restore the natural overbank flooding regime. Ditches
and subsurface drainage tiles located within the
conservation easement will be filled or removed to . 7
improve hydrology. Riparian wetlands within the � ` ` �� � "
project area will be planted with native wetland v rs , ' � '
species specific to the target wetland community type
of Bottomland Hardwood Forest as outlined in Section 6.9 and invasive species will be treated.Wetland
potential and hydrology were assessed with soils analysis and existing groundwater gages. Reference
wetland community data was used to propose wetland herbaceous and woody vegetation planting.
Wildlands analyzed information presented below to understand how existing incised streams and
farming practices have affected current hydrologic conditions, site topography and hydric soil
development.This analysis included evaluation of how stream restoration and management of runoff
and drainage at the site could be used to create more favorable future hydrologic conditions for hydric
soil development in the proposed wetland areas.
6.7.1 Hydric Soils Investigation
A preliminary hydric soils investigation was conducted in December 2018 by a licensed soil scientist
(LSS),followed up by an additional boring study in March 2020 to assess the extent and depth of hydric
soil indicators on site.The field assessments have been combined into one summary report and figure
(Appendix 5).The findings were used to indicate wetland re-establishment potential and depth of
potential overburden material from the historic manipulation of site soils for agricultural purposes.
Areas containing hydric soils but lacking a wetland hydrologic regime were likely functional wetlands
prior to floodplain fill and drainage activities. Proposed wetland re-establishment areas were mapped as
the Chewacla soil series by NRCS. However, hydric soils observed in Wetlands 1 and 3 were more
consistent with the Wehadkee soil series while soils in Wetlands 2 and 4 were more consistent with
Chewacla. According to the USACE Wilmington District Stream and Wetland Compensatory Mitigation
Update (2016),the established Wetland Saturation Threshold for the Chewacla and Wehadkee soil
series in the North Carolina Piedmont ranges from 10-16%.
A total of 91 hand augured soil borings were performed as part of the hydric soil investigations. Soil
borings were classified as non-hydric within 10 inches of soil surface, hydric soils with a depleted matrix
(F3), and hydric soils considered piedmont floodplain soils (F19). At boring locations,the depth below
the existing land surface to hydric soil indicator was noted.The report from the LSS(Appendix 5)
supports Wildlands' proposed wetland restoration plans and provides supporting data for the specific
approaches and activities proposed. Along UT1,the review of historic aerial photography coupled with
field observations of topography and soils are indicative of fill placement over historic wetlands.

6.7.2 Reference Wetlands
An existing wetland approximately 7 miles from the Site, Oak Hill Dairy Reference Wetland
and adjacent to Wildlands' Owl's Den Mitigation Site in r,.
Lincoln County, is a mature Piedmont Bottomland Forest
reference within the floodplain of Howards Creek. Review
of historical aerials and field conditions reveal no recent (•
disturbance to the wetland. Mature vegetation is
established and the natural flooding regime has been
preserved.The hydrology of this system is intermittently,
temporarily, or seasonally flooded.While the hydrology ` '_ ';
data collected at the Owl's Den reference site indicates ;
that it is wetter than what is anticipated at Oak Hill Diary, _ .
the vegetation provides a good reference on a site that
exhibits similar soil types and topographic form to the Oak Hill Site.
The vegetation at the reference site is being used as a basis for the planting plan for the wetland
restoration and creation on the project Site.The existing vegetation communities at the reference site
are typical of a Bottom land Hardwood Forest and include mature canopy tree species, subcanopy and
shrub species, as well as an herbaceous layer. Dominant canopy species include river birch, green ash,
sycamore, box elder, and red maple. Understory species include ironwood and spicebush.The
herbaceous layer within the reference wetland includes arrow arum,jewelweed, and lizard's tail, with
microstegium also present.
6.7.3 Measured Hydrologic Data
Seven groundwater monitoring gages were installed throughout the Site on December 20, 2019 and
monitored through September 8, 2020.The location of the existing groundwater gages is shown in
Figure 2. Gages were placed throughout the existing floodplain at the site to evaluate the existing
groundwater elevations throughout the growing season (March 20 to November 14 (239 days)for
Gastonia, North Carolina).Table 27 summarizes the available groundwater data.
For the 2020 growing season, none of the seven groundwater gages installed on the Site met the
Wetland Saturation Threshold. Groundwater gages#1 and#3 were located in the floodplain along Reach
3 and Reach 4 of Oak Hill Creek and logged more consecutive and cumulative days with the water table
within 12 inches of the ground surface than the other gages.These gages also have a more muted
response to rainfall suggesting a strong toe of slope hydrology that results in a more prolonged and
evenly distributed hydrologic input under current conditions. Groundwater gage#2 was located closer
to Oak Hill Creek in a position influenced by natural levy formation or manmade side-casting and much
closer to the drawdown influence of the incised Oak Hill Creek. Gage#4 appears to have good potential
to meet criteria based on a more prolonged drawdown after rainfall and a water table that is drastically
affected by site drainage. It is adversely impacted by the downstream ditch and subsurface wood drain
tile lowering hydrology in existing Wetland B. Gages#5-7 were not very close to achieving prolonged
saturation within the upper 12" of the soil column. Gage#5 is adjacent to the start of the ditch draining
existing Wetland B and is also perpendicular and in close proximity to a meander bend in Oak Hill Creek
that is incised five feet below the grade of the floodplain on which gage#5 is situated -a wooden
drainage tile is visible in the left bank of the creek coming from the direction of the gage. Gages#6 & 7
are located approximately 5' below the adjacent incised UT1 channel.This high ground was noted in the
LSS' report as a topographic anomaly attributable to historic channel manipulation for agricultural
purposes (Appendix 5). These gages are in narrower valleys before the confluence of the Oak Hill Creek
with UT1.The drawdown influence is corresponding more pronounced from incised and ditched creek
Oak Hill Dairy Mitigation Site Draft Mitigation Plan

channels located in closer proximity. At the same time,the hillslope hydrology is less pronounced than
the influence of the 15 acres of ephemeral flow entering the Site near gages#1& 3.

the channels likely involved side-casting of dredged material to -
confine the channel and may have established a lower channel
grade or led to subsequent down-cutting and a resulting
lowering of the groundwater table on the Site. Multiple
headcuts are still advancing upstream of gages#6 &7 on UT1, :f
and the existing culvert at Roy Eaker Road is perched indicating
•
prior headcutting as well. 140
This channel manipulation has led to a lower water table
throughout much of the site as evidenced by hydric soil
indicators and a decrease in the frequency of floodplain
activation, primary factors for the absence of functioning
floodplain wetland complexes at the Site.

Several low gradient ditches at the Site drain wet areas of the floodplain. Many of these ditches show up
as linear wetlands in the PJD as they have not been recently maintained, are very wet, and have wetland
vegetation.The largest example of this is a ditch that runs along the toe of the valley in the left
floodplain of Oak Hill Creek Reach 3 and Reach 4.This ditch
captures water at the toe of slope and routes it to an outlet
ditch that parallels Robert Road.This water is then channeled to 1984 Infrared Photo Depicting Drainage
Ditches on Left Side and Center of Valley
the culvert under Robert Road at the downstream limits of the
Site. As such,toe of slope hydrology bypasses the left floodplain
of Oak Hill Creek Reach 3 and Reach 4. Similar ditches also occur
in the left floodplain of Oak Hill Creek Reach 1 and Reach 2 and
the right floodplain of UT1 Reach 2.
6.7.5 Proposed Wetland Design
The proposed stream work and wetland grading will restore
wetland hydrology to filled and drained areas of the site.
Priority 1 stream restoration of profile and cross-section will
increase the frequency of overbank flooding.This stream
restoration approach will also reduce groundwater flow
gradient from the toe of slope and floodplain wetland areas to
the stream, resulting in less drawdown in the water table across
the Site. Grading to remove ditches and subsurface drainage
features within the Site will also improve the wetland - —
hydrology.The proposed grading will eliminate linear ditches •
and plug ditch outlets to the stream, remove or reduce side cast '''API , + : .
material from ditch and stream banks, and remove areas of field
fill and crowning.This work will promote a more natural
infiltration and groundwater flow regime through the site and remove overburden from buried hydric
soils.
In all wetland rehabilitation and re-establishment areas (areas credited at both 1:1 and 1.5:1 ratios),
grading cuts of greater than 12 inches account for 16.8%of the area.These cut areas are mostly
relegated to the berms and sidecast piles found in the left floodplain of Oak Hill Creek Reaches 3 and 4
and the right floodplain of UT1 as shown in Figure 10.Grading in these areas was dictated by the stream
design, where the proposed stream bankfull was placed at the existing low point in the valley. Sidecast
piles from maintenance of the existing stream and the wetland toe ditch created high points on either
side of the proposed stream greater than 12 inches.These high points will be removed to connect the
proposed stream to existing wetlands and to allow the stream access to a majority of the floodplain
during flood stages. Creation wetland areas contain more extensive grading with areas of grading
greater than 12 inches accounting for about 31.8%of the total creation area.
Wetland rehabilitation at a credit ratio of 1:1 was proposed for existing wetlands that were delineated
in the left floodplain along Oak Hill Creek Reaches 3 and 4.While no expansion of wetland area will
occur in the 1:1 wetland rehabilitation area, wetland function will uplift by a large margin in these areas.
A majority of the area proposed at 1:1 wetland rehabilitation consists of an agricultural field that is
plowed and planted in some years or an existing ditch at the toe of slope. NC WAM forms indicate that
these areas are very low or poor functioning in all categories. Existing wetlands in other areas of the Site
were found to be in better condition and are proposed as wetland rehabilitation at a 1.5:1 credit ratio.
Collectively,the proposed changes to the Site are anticipated to enhance the hydrology to meet targets
consistent with the formation and support of wetlands and the targeted communities.
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 35 January 14,2021

In many areas within the site,the LSS hydric soil assessment indicated hydric indicators below 10" and
there was less obvious evidence of prior area-specific manipulation.Wildlands' review of historic and
topographic data, and the distribution of remnant wetlands throughout the site led us to the conclusion
that some or many of these areas were potentially part of historic wetlands, or that proposed site
activities are likely to result in wetland formation in many of these areas supporting floodplain wetland
functions. For this reason, we have proposed wetland creation in select areas where assessment data
was insufficient to support re-establishment.
6.8 Stormwater BMPs
Two stormwater BMPs are proposed for the Site, as depicted on Figure 9.
Runoff from the dairy feedlot on the left side of UT1A enters UT1A as dispersed overland flow and
enters the left floodplain of UT1 through an existing swale. BMP 1 will be established within the
conservation easement at the outlet of the existing swale to capture and treat the drainage from this
area. Approximately 3 acres drains to the proposed BMP, including the farmhouse and other upland
areas. BMP 1 has been designed to provide storage and treatment and to step the runoff down from the
terrace onto the left floodplain of UT1. It will be outlet to a flow dispersing feature onto the floodplain
to filter through the riparian buffer into UT1.
BMP 2 will be installed outside of the proposed wetland re-establishment along Oak Hill Creek Reach 3
and will slow and provide volume storage and treatment for the contributing 15-acre drainage that
starts near the dairy waste lagoon and includes adjacent fields in crop production, entering the
proposed BMP at the downstream limits of an NRCS grassed swale practice.While the waste lagoon is
designed not to overtop, it has overtopped on one prior instance and the BMP provides an additional
buffer to the wetlands and floodplain of Oak Hill Creek and treats a significant area of cultivated land
that may be used in the future for grazing. Additional easement has been obtained in this area for the
BMP.The outlet of BMP 2 will be designed for diffusion of the collected outflow into the adjacent
floodplain and wetlands and a high flow outlet to manage large rainfall events in a stable manner.
The two BMPs will be planted with wetland seeding, plugs and livestakes. No direct mitigation credit is
requested for BMPs.
The primary maintenance risks for the BMPs are erosion issues throughout the BMP system as well as
sediment loads filling the BMP basins and reducing capacity over long-term time scales. Minimizing
maintenance is a major design criterion for the BMPs.
To reduce erosion in the BMP system and to promote vegetation establishment,the banks of the BMP
basins will be laid back as much as practical. Slopes steeper than 4:1 will be stabilized with erosion
control matting. All areas associated with the BMP systems that have been disturbed will be seeded
and will be monitored for vegetation establishment after construction has been completed. Areas
without sufficient vegetation will be prepared and re-seeded until adequate vegetation is established.
The BMP overflow areas were designed with low slopes from the BMP basin to the Conservation
Easement boundaries to reduce the risk of scour or downcutting in the overflow conveyance. Due to
existing topography at the site, conveyance areas upslope of the BMPs will have higher slopes and a
potential for headcuts. Potential nick points in the upslope conveyances will be addressed with
structures (rock steps, etc), pools,the addition of rock to harden the conveyance bed in key areas, and
erosion control matting where needed.
Sediment loads filling the BMP basin are likely unavoidable over long-term time scales and should be
interpreted as the BMP functioning properly. Due to the relative size of the BMPs compared to the
contributing watersheds, it is expected that it may take several years to a decade before BMP capacity
Oak Hill Dairy Mitigation Site Draft Mitigation Plan
DMS ID No. 100120 Page 36 January 14,2021

is reduced such that performance suffers.
6.9 Vegetation, Planting Plan, and Land Management
Non-forested areas within the conservation easement will be planted, which includes additional buffer
areas beyond the minimum requirement of 50 feet from top of bank. Riparian buffers will be planted
with early successional native vegetation chosen to develop a forested riparian zone.The specific
species composition to be planted was selected based on the target community type, observation of
occurrence of species in riparian buffers adjacent to the Site, and best professional judgement on
species establishment and anticipated Site conditions in the early years following project
implementation. Species chosen for the planting plan are listed on table 28 below and on Sheet 4.1 of
the Preliminary Plans located in Appendix 12. Wildlands used the following community types as targets
for species selection for the site:
• Piedmont/Low Mountain Alluvial Forest
• Piedmont Bottomland Forest
• Dry—Mesic Oak—Hickory Forest
• Mesic Mixed Hardwood Forest
The riparian buffer and most wetland areas will be planted with bare root seedlings. In addition,the
stream banks will be planted with live stakes and the channel toe will be planted with multiple
herbaceous species. Permanent native herbaceous seed will be spread on streambanks,floodplain
areas, and wetlands including all disturbed areas within the project easement. Bare root seedlings and
live stakes will be planted in the dormant season between November 15 and March 15. Figure 12
illustrates the proposed planting zones throughout the Site.
Land management activities on the site will largely focus on treating invasive plant populations and
pasture grasses. Existing invasive plant populations on the site include Bamboo (Phyllostachys aurea),
Chinese privet (Ligustrum sinense),Japanese honeysuckle (Lonicera japonica),Japanese knotweed
(Polygonum cuspidatum), kudzu (Pueraria montana), English ivy (Hedera helix) and marsh dewflower
(Murdannia keisak). Limited populations of multiflora rose(Rosa multiflora)also exist on the site. Some
of the existing invasive species and pasture grasses along restoration and enhancement reaches will be
treated preconstruction,while others will be treated primarily by mechanical removal during
construction.The extent of invasive species coverage will be monitored, mapped, and controlled as
necessary throughout the required monitoring period. Please refer to Appendix 8 for the post
construction invasive species plan. Additional monitoring and maintenance issues regarding vegetation
are in Sections 8 and 9 and Appendix 10.

6.10 Project Risk Management
The risks for the final design, construction and monitoring and long-term success of this project have
been considered and evaluated for mitigation and minimization of identified risks.The summary below
discusses common and perceived project-specific risks, including permitting issues, easement issues,
instability or compromised function of stream or wetland assets, issues with crossing stability or use,
adjacent and upstream land use considerations, and invasive species concerns.
Urban flows from Oak Hill Creek are a concern to the stability of channels and floodplains, particularly
on a short-term basis after construction due to flashy flows and an increased frequency of out-of-bank
events. Wildlands modified the approach to Reach 1 to include more comprehensive floodplain
establishment and address the issue with existing benching being inaccessible at flows below the 10-
year USGS return interval. Wildlands anticipates that a good stand of vegetation can be established on
floodplains to help reduce high flow impacts. In addition,floodplain roughening will be proposed on
floodplains using onsite wood and brush, live wattles or cuttings during the first dormant season, and/or
through shaping of hummocky topography to mimic natural floodplain roughness. A related concern is
the stability of crossings. In order to reduce crossing risk,Wildlands and the landowners were able to
agree on changing out a proposed culvert on Oak Hill Creek Reach 1 for a ford.The ford will allow for
more natural floodplain grading and should be a more stable option on this creek influenced by an
urban flow regime. Both Oak Hill Creek and UT1 crossings have been designed so that the wide
floodplains can serve as a flood bypass of the proposed crossings. On UT1,this will allow flows in excess
of bankfull to access a wide floodplain on the right-hand side of the crossing,thereby relieving the
structure of excess stresses from high flow events or debris.
Wildlands had some concerns during development of the proposal that existing heavy use and cultivated
upland activities could impact project assets during heavy rainfall. As a result,two BMPs were proposed
to reduce the annual impact of upland runoff on water quality and to spread out and disperse more
these more concentrated flow paths over a broader area that would allow the natural buffer to function
as intended. Wildlands will observe BMP function and make minor adjustments as necessary to ensure
that the practices function sustainably on their own after vegetation establishes.
Invasive species management is a primary consideration on this Site. Wildlands is planning to begin
treatment of infestations prior to construction.
All stream and wetland projects have some risk for beaver colonization.There is no onsite evidence of
current or past beaver activity in the project limits. If beaver move into the project areas, Wildlands will
follow the Maintenance Plan (Appendix 10)to address the issue.
Should utility/roadway maintenance work occur in the future and encroach within the conservation
easement,Wildlands will follow the Maintenance Plan to repair disturbed signage or damaged stream
areas.
7.0 Performance Standards
The stream and wetland performance standards for the project will follow approved performance
standards presented in the DMS Mitigation Plan Template (Version 2.3,June 2017),the Annual
Monitoring Template (June 2017), and the Wilmington District Stream and Wetland Compensatory
Mitigation Update issued October 2016 by the USACE and NCIRT. Annual monitoring and routine site
visits will be conducted by a qualified scientist to assess the condition of the finished project. Specific
performance standards that apply to this project are those described in the 2016 Compensatory

11.0 Determination of Credits
The final stream credits associated with the Site are listed in Table 32. Stream restoration is proposed at
a ratio of 1:1, stream enhancement (El) at a ratio of 1.5:1, and stream preservation at a ratio of 10:1.
Wetland re-establishment is proposed at 1:1, rehabilitation is proposed at 1:1 for enhancement of low
NCWAM rating wetlands that are currently being farmed or are actively maintained ditches and 1.5:1 for
rehabilitation of moderate NCWAM rating wetlands (see Table 12 for NCWAM rating), and creation is
proposed at 3:1. No credit is sought for BMPs, nor for proposed channel extensions of UT2 and UT3 to
tie into the realigned Oak Hill Creek mainstem channel.
Buffers proposed throughout the Site meet the minimum required 50-foot standard width for Piedmont
streams, and in most cases,far exceed it.The credit release schedule is provided in Appendix 13.

Indicate Which of the Following Apply:
A. Preliminary Determination
14 There appear to be waters on the above described project area/property,that may be subject to Section 404 of the Clean Water
Act(CWA)(33 USC§ 1344)and/or Section 10 of the Rivers and Harbors Act(RHA)(33 USC§403).The waters have been
delineated,and the delineation has been verified by the Corps to be sufficiently accurate and reliable. The approximate boundaries
of these waters are shown on the enclosed delineation map dated 12/7/2020.Therefore this preliminary jurisdiction determination
may be used in the permit evaluation process,including determining compensatory mitigation.For purposes of computation of
impacts,compensatory mitigation requirements,and other resource protection measures,a permit decision made on the basis of a
preliminary JD will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they
are jurisdictional waters of the U.S.This preliminary determination is not an appealable action under the Regulatory Program
Administrative Appeal Process(Reference 33 CFR Part 331).However,you may request an approved JD,which is an appealable
action,by contacting the Corps district for further instruction.
❑ There appear to be waters on the above described project area/property,that may be subject to Section 404 of the Clean Water
Act(CWA)(33 USC§ 1344)and/or Section 10 of the Rivers and Harbors Act(RHA)(33 USC§403).However,since the waters
have not been properly delineated,this preliminary jurisdiction determination may not be used in the permit evaluation process.
Without a verified wetland delineation,this preliminary determination is merely an effective presumption of CWA/RHA
jurisdiction over all of the waters at the project area,which is not sufficiently accurate and reliable to support an enforceable
permit decision.We recommend that you have the waters on your project area/property delineated.As the Corps may not be able
to accomplish this wetland delineation in a timely manner,you may wish to obtain a consultant to conduct a delineation that can
be verified by the Corps.
B. Approved Determination
❑ There are Navigable Waters of the United States within the above described project area/property subject to the permit
requirements of Section 10 of the Rivers and Harbors Act(RHA)(33 USC§403)and Section 404 of the Clean Water Act
(CWA)(33 USC§ 1344). Unless there is a change in law or our published regulations,this determination may be relied upon for
a period not to exceed five years from the date of this notification.
❑ There are waterson the above described project area/property subject to the permit requirements of Section 404 of the Clean
Water Act(CWA)(33 USC§ 1344). Unless there is a change in the law or our published regulations,this determination may be
relied upon for a period not to exceed five years from the date of this notification.
❑We recommend you have the waters on your project area/property delineated. As the Corps may not be able to accomplish
this wetland delineation in a timely manner,you may wish to obtain a consultant to conduct a delineation that can be verified by
the Corps.
❑The waters on your project area/property have been delineated and the delineation has been verified by the Corps.The
approximate boundaries of these waters are shown on the enclosed delineation map dated DATE.We strongly suggest you have
this delineation surveyed. Upon completion,this survey should be reviewed and verified by the Corps. Once verified,this survey

SAW-2019-00833
will provide an accurate depiction of all areas subject to CWA jurisdiction on your property which,provided there is no change in
the law or our published regulations,may be relied upon for a period not to exceed five years.
❑The waters have been delineated and surveyed and are accurately depicted on the plat signed by the Corps Regulatory Official
identified below onDATE.Unless there is a change in the law or our published regulations,this determination may be relied
upon for a period not to exceed five years from the date of this notification.
❑ There are no waters of the U.S.,to include wetlands,present on the above described project area/property which are subject to the
permit requirements of Section 404 of the Clean Water Act(33 USC 1344). Unless there is a change in the law or our published
regulations,this determination may be relied upon for a period not to exceed five years from the date of this notification.
❑ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act(CAMA).
You should contact the Division of Coastal Management in Morehead City,NC,at(252)808-2808 to determine their
requirements.
Placement of dredged or fill material within waters of the US,including wetlands,without a Department of the Army permit may
constitute a violation of Section 301 of the Clean Water Act(33 USC§ 1311). Placement of dredged or fill material,construction or
placement of structures,or work within navigable waters of the United States without a Department of the Army permit may
constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act(33 USC§401 and/or 403).If you have any questions
regarding this determination and/or the Corps regulatory program,please contact Krystvnka B Sty2ar at 252-545-0507 or
krystynka.b.stvgar(a usace.armv.mil.

1. The Corps of Engineers believes that there may be jurisdictional aquatic resources in the
review area, and the requestor of this PJD is hereby advised of his or her option to request
and obtain an approved JD (AJD) for that review area based on an informed decision after
having discussed the various types of JDs and their characteristics and circumstances when
they may be appropriate.
2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide
General Permit (NWP) or other general permit verification requiring "pre- construction
notification" (PCN), or requests verification for a non-reporting NWP or other general
permit, and the permit applicant has not requested an AJD for the activity, the permit
applicant is hereby made aware that: (1) the permit applicant has elected to seek a permit
authorization based on a PJD,which does not make an official determination of
jurisdictional aquatic resources; (2) the applicant has the option to request an AJD before
accepting the terms and conditions of the permit authorization, and that basing a permit
authorization on an AJD could possibly result in less compensatory mitigation being
required or different special conditions; (3) the applicant has the right to request an
individual permit rather than accepting the terms and conditions of the NWP or other
general permit authorization; (4) the applicant can accept a permit authorization and
thereby agree to comply with all the terms and conditions of that permit, including
whatever mitigation requirements the Corps has determined to be necessary; (5)
undertaking any activity in reliance upon the subject permit authorization without
requesting an AJD constitutes the applicant's acceptance of the use of the PJD; (6)
accepting a permit authorization (e.g., signing a proffered individual permit) or undertaking
any activity in reliance on any form of Corps permit authorization based on a PJD
constitutes agreement that all aquatic resources in the review area affected in any way by
that activity will be treated as jurisdictional, and waives any challenge to such jurisdiction
in any administrative orjudicial compliance or enforcement action, or in any administrative
appeal or in any Federal court; and (7) whether the applicant elects to use either an AJD or
a PJD, the JD will be processed as soon as practicable. Further, an AJD, a proffered
individual permit (and all terms and conditions contained therein), or individual permit
denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an
administrative appeal, it becomes appropriate to make an official determination whether
geographic jurisdiction exists over aquatic resources in the review area, or to provide an
official delineation of jurisdictional aquatic resources in the review area, the Corps will
provide an AJD to accomplish that result, as soon as is practicable. This PJD finds that
there "may be"waters of the U.S. and/or that there "may be"navigable waters of the U.S.
on the subject review area, and identifies all aquatic features in the review area that could
be affected by the proposed activity, based on the following information:

List species:
▪Designated Critical Habitat(list species)
19.Are additional stream information/supplementary measurements included in"Notes/Sketch"section or attached? ❑Yes No
1. Channel Water-assessment reach metric(skip for Size 1 streams and Tidal Marsh Streams)
®A Water throughout assessment reach.
❑B No flow,water in pools only.
❑C No water in assessment reach.
2. Evidence of Flow Restriction-assessment reach metric
❑A At least 10% of assessment reach in-stream habitat or riffle-pool sequence is severely affected by a flow restriction or fill to the
point of obstructing flow or a channel choked with aquatic macrophytes or ponded water or impoundment on flood or ebb within
the assessment reach (examples: undersized or perched culverts, causeways that constrict the channel,tidal gates,debris jams,
beaver dams).
®B NotA
3. Feature Pattern-assessment reach metric
❑A A majority of the assessment reach has altered pattern (examples:straightening, modification above or below culvert).
®B NotA
4. Feature Longitudinal Profile-assessment reach metric
❑A Majority of assessment reach has a substantially altered stream profile(examples: channel down-cutting,existing damming,over
widening, active aggradation, dredging, and excavation where appropriate channel profile has not reformed from any of these
disturbances).
®B NotA
5. Signs of Active Instability-assessment reach metric
Consider only current instability, not past events from which the stream has currently recovered. Examples of instability include
active bank failure, active channel down-cutting(head-cut),active widening,and artificial hardening (such as concrete,gabion, rip-rap).
❑A < 10%of channel unstable
❑B 10 to 25%of channel unstable
®C >25%of channel unstable

6. Streamside Area Interaction—streamside area metric
Consider for the Left Bank(LB)and the Right Bank(RB).
LB RB
❑A ❑A Little or no evidence of conditions that adversely affect reference interaction
®B ®B Moderate evidence of conditions (examples: berms, levees,down-cutting, aggradation, dredging)that adversely affect
reference interaction(examples: limited streamside area access,disruption of flood flows through streamside area,leaky
or intermittent bulkheads,causeways with floodplain constriction, minor ditching[including mosquito ditching])
❑C ❑C Extensive evidence of conditions that adversely affect reference interaction (little to no floodplain/intertidal zone access
[examples: causeways with floodplain and channel constriction,bulkheads,retaining walls,fill,stream incision,disruption
of flood flows through streamside area]or too much floodplain/intertidal zone access[examples:impoundments,intensive
mosquito ditching]) or floodplain/intertidal zone unnaturally absent or assessment reach is a man-made feature on an
interstream divide
7. Water Quality Stressors—assessment reach/intertidal zone metric
Check all that apply.
❑A Discolored water in stream or intertidal zone(milky white,blue,unnatural water discoloration,oil sheen,stream foam)
❑B Excessive sedimentation (burying of stream features or intertidal zone)
❑C Noticeable evidence of pollutant discharges entering the assessment reach and causing a water quality problem
❑D Odor(not including natural sulfide odors)
❑E Current published or collected data indicating degraded water quality in the assessment reach. Cite source in "Notes/Sketch"
section.
❑F Livestock with access to stream or intertidal zone
❑G Excessive algae in stream or intertidal zone
❑H Degraded marsh vegetation in the intertidal zone(removal,burning, regular mowing,destruction,etc)
❑1 Other: (explain in"Notes/Sketch"section)
• Little to no stressors
8. Recent Weather—watershed metric(skip for Tidal Marsh Streams)
For Size 1 or 2 streams, D1 drought or higher is considered a drought;for Size 3 or 4 streams,D2 drought or higher is considered a drought.
❑A Drought conditions and no rainfall or rainfall not exceeding 1 inch within the last 48 hours
❑B Drought conditions and rainfall exceeding 1 inch within the last 48 hours
®C No drought conditions
9. Large or Dangerous Stream—assessment reach metric
❑Yes ®No Is stream is too large or dangerous to assess? If Yes,skip to Metric 13(Streamside Area Ground Surface Condition).
10. Natural In-stream Habitat Types—assessment reach metric
10a. ❑Yes No Degraded in-stream habitat over majority of the assessment reach (examples of stressors include excessive
sedimentation, mining, excavation, in-stream hardening [for example, rip-rap], recent dredging, and snagging)
(evaluate for Size 4 Coastal Plain streams only,then skip to Metric 12)
10b. Check all that occur(occurs if>5%coverage of assessment reach)(skip for Size 4 Coastal Plain streams)
❑A Multiple aquatic macrophytes and aquatic mosses w OF 5%oysters or other natural hard bottoms
(include liverworts,lichens,and algal mats) F E ❑G Submerged aquatic vegetation
®B Multiple sticks and/or leaf packs and/or emergent o . ❑H Low-tide refugia(pools)

INTRODUCTION
Soil & Environmental Consultants, PA(S&EC, PA) was retained to perform an evaluation to assess the
presence and extent of hydric soils onsite. Proposed Wetland area 1 is currently planted in winter wheat
or fallow and Proposed Wetland 3 is mostly fescue grass. Proposed Wetland areas 2 and 4 have been
maintained in the past but currently have mostly herbaceous vegetation with some small saplings
intermixed. Proposed Wetland areas 1 and 3 contained hydric soil indicators F3, F19 or both within 10" of
the surface while Proposed Wetland areas 2 &4 contained some borings with hydric soil indicators
present at depths greater than 10" but less than or equal to 18". (see attached Figure A-Soil
Investigation Map)
METHODOLOGY
On December 27th, 2018 and March 6th, 2020 Kevin Martin (LSS, PWS) of S&EC, PA performed hydric soil
evaluations at the site. Ninety-one Hand auger borings were advanced on the property at locations as
appropriate to approximately estimate the location and extent of hydric soils within the project area (see
attached Figure A- Soil Investigation Map). Each soil boring was evaluated to assess the presence or
absence of hydric soil indicators. Hydric soil indicators were identified utilizing the NRCS Field Indicators
of Hydric Soils in the Unities States-A Guide for Identifying and Delineating Hydric Soils (Version 8.2,
2018).
All areas evaluated are mapped as the somewhat poorly drained Chewacla soil series (Fine-loamy, mixed,
active,thermic Fluvaquentic Dystrudepts) except for a few small areas along the western perimeter of
Proposed Wetland 1 that were mapped as the well-drained Pacolet soil series. Most hydric soils observed
onsite within Proposed Wetlands areas 1 and 3 were more like the Wehadkee soil series (Fine-loamy,
mixed, active, nonacid, thermic Fluvaquentic Endoaquepts) because they contained a horizon with a
dominant chroma of 2 or less in the upper 20 inches of the soil.While most of the soils in Proposed
Wetland area 2 and 4 were more like the Chewacla soil series since they have a horizon with a dominant
chroma of more than 2 in the upper 20 inches of the soil.
Non hydric soils observed along the perimeter of the Proposed Wetland areas 1 and 3 were most like the
well to moderately well drained Congaree soil series.The Congaree soils were generally present close to
the streams.
RESULTS
Approximately 91 soil borings were performed within the study area. Soil characteristics were
evaluated and all areas identified as containing hydric soils met the hydric soil criteria described
below.
Soil boring locations are indicated on the attached Figure A- Soil Investigation Map. The type of
hydric soil indicator at each being is shown on the Soil Investigation Map. The depth to the
hydric soil indicator(s) for each boring is listed within Table 1— Depth to Hydric Soil Indicator and
Type.

Red circles on the Map—are borings where hydric soil indicators were not observed in the top
10" of the soil profile. Hydric indicators may have been observed below 10" of the soil surface
depending on the boring location (see the attached table for further details).
Orange circles on the Map are borings where hydric soil indicators were not observed in the
top 10" of the soil profile, but were observed within 18" of the current soil surface. This area
seems to contain a buried hydric soil that existed prior to 1956. A review of aerial photos in 1938
and 1951 show that the stream in this area was at a different location (further south) than its
present location. The realignment of the stream appears to have resulted in side-cast material
from the rerouted stream being deposited in this area. One can still see an "unnatural"
landsurface elevation change adjacent to where the original stream location appears to have
been. This explains why the area at toeslope of the upland south of the existing stream contains
hydric soils but the area between there and the stream contain hydric indicators deeper in the
soil profile. Soil profile description bh57N is typical of this area. Soil profile description bh66N is
believed to be at a point where the pre1956 stream was originally located. (see the attached
Table 1— Depth to Hydric Soil Indicator and Type for further details).
Blue Plus Signs and Blue Circles- are hydric soil areas containing a depleted matrix (F3) indicator
within 10" of current land surface (these borings may also have had the F19 indicator above the
F3, see the attached Table 1 for details of where this occurred). Soil profile BH15 and bh56A are
representative of these areas.
Green Triangles and Green Circles- are hydric soils areas containing a Piedmont floodplain
indicator F19 within 10" but not a depleted matrix F3 within 10" (these borings may have also
had the F3 indicator below the F19 indicator, see the attached Table 1 for further details). Soil
profile description BH16 is typical of this area.
Indicator F3: Depleted Matrix
Technical Description: A layer that has a depleted matrix with 60 percent
or more chroma of 2 or less and that has a minimum thickness of either:
(a) 2 in. (5 cm) if the 2 in. (5 cm) is entirely within the upper 6 in. (15 cm)
of the soil, or
(b) 6 in. (15 cm) starting within 10 in. (25 cm) of the soil surface.
Indicator F19: Piedmont Floodplain Soils
On flood plain, a mineral layer at least 15 cm (6 inches) thick, starting at a depth <25cm (10
inches) from the soil surface, with a matrix (60 percent or more of the volume) chroma of less
than 4 and 20 percent or more distinct or prominent redox concentrations occurring as soft
masses or pore linings.

Categorical Exclusion
SUMMARY

Comprehensive Environmental Response, Compensation, and Liability Act(CERCLA)
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) provides a
Federal "Superfund"to clean up uncontrolled or abandoned hazardous-waste sites as well as accidents,
spills, and other emergency releases of pollutants and contaminants into the environment.
As the Oak Hill Dairy Mitigation Site is a full-delivery project; an EDR Radius Map Report with Geocheck
was ordered for the site through Environmental Data Resources, Inc on December 12, 2018. Neither the
target property nor the adjacent properties were listed in any of the Federal, State, or Tribal
environmental databases searched by the EDR.The assessment revealed no evidence of any"recognized
environmental conditions" in connection with the target property.
The target property, Eaker Dairy, Inc., has an active NPDES permit (National Pollutant Discharge
Elimination System) and an active AOP (Air Operating Permit) associated with the cattle waste lagoon
located on the target property. The lagoon is located outside of the Oak Hill Dairy conservation
easement and will not be disturbed by the stream and wetland mitigation project. The dairy is in full
compliance with their NPDES and AOC permits.
The Executive Summary of the EDR report is included in the Appendix.The full report is available if
needed.
National Historic Preservation Act(Section 106)
The National Historic Preservation Act declares a national policy of historic preservation to protect,
rehabilitate, restore, and reuse districts, sites, buildings, structures, and objects significant in American
architecture, history, archaeology, and culture, and Section 106 mandates that federal agencies take
into account the effect of an undertaking on a property that is included in, or is eligible for inclusion in,
the National Register of Historic Places.
The State Historic Preservation Office (SHPO) responded to a United States Army Corps of Engineers
public notice requesting comment on the Oak Hill Dairy Mitigation Site on July 12, 2019. SHPO stated
they were aware of"no historic resources which would be affected by the project" and would have no
further comment. All correspondence related to Section 106 is included in the Appendix.
Uniform Relocation Assistance and Real Property Acquisition Policies Act(Uniform Act)
These acts, collectively known as the Uniform Act, provide for uniform and equitable treatment of
persons displaced from their homes, businesses, non-profit associations, or farms by federal and
federally-assisted programs, and establish uniform and equitable land acquisition policies.
Oak Hill Dairy Mitigation Site is a full-delivery project that includes land acquisition. Notification of the
fair market value of the project property and the lack of condemnation authority by Wildlands was
included in the signed Option Agreements for the project properties. A copy of the relevant section of
each of the Option Agreements are included in the Appendix.
American Indian Religious Freedom Act(AIRFA)
The American Indian Religious Freedom Act provides for the protection and preservation of places of
religious importance to American Indians, Eskimos, and Native Hawaiians.
The Cherokee Nation Tribal Historic Preservation Office (THPO) commented on the project, July 17,
2019, in response to the United States Army Corps of Engineers (USACE) public notice for the project.
The Cherokee Nation THPO stated they "did not foresee this project imparting impacts to Cherokee
cultural resources at this time." NCDMS requested additional review and comment from the Eastern

archeological or religious resources related to the Oak Hill Dairy Mitigation Site on June 19, 2019. At this
time, DMS has not received a response from either the Eastern Bank of Cherokee or the Untied
Keetoowah Band of Cherokee.
All correspondence related to AIRFA is included in the Appendix.
Endangered Species Act(ESA)
Section 7 of the ESA requires federal agencies, in consultation with and with the assistance of the
Secretary of the Interior or of Commerce, as appropriate,to ensure that actions they authorize,fund or
carry out are not likely to jeopardize the continued existence of threatened or endangered species or
result in the destruction or adverse modification of critical habitat for these species.
The Gaston County listed endangered species includes the bog turtle (Glyptemys muhlenbergii),the
northern long-eared bat (NLEB) (Myotis septentrionalis),the dwarf-flowered heartleaf(Hexastylis
naniflora), and the Schweinitz's sunflower(Helianthus schweinitzii). The United States Fish and Wildlife
Service (USFWS) does not currently list any Critical Habitat Designations for the Federally listed species
within Gaston County nor are there any current known occurrences of the above listed species within a
2-mile radius of the project site. The project site is located more than 40 miles from the nearest known
hibernaculum for the NLEB. (https://www.fws.gov/asheville/htmis/project_review/NLEB_in_WNC.html).
Results of a pedestrian survey conducted on June 18, 2019, indicated that the project area provides
potential summer roosting for the NLEB and areas of suitable habitat for the bog turtle,the dwarf-
flowered heartleaf, and the Schweinitz's sunflower. No individuals or populations of the four above
referenced species were documented on-site.
NLEB
Wildlands determined the project "may affect, not likely to adversely affect"the NLEB. Forested
habitats containing trees at least 3-inch dbh in the project area provide suitable habitat for NLEB. Due to
the decline of the NLEB population from the White Nose Syndrome (WNS),the United States Fish and
Wildlife Service (USFWS) has issued the finalization of a special rule under section 4(d) of the ESA to
addresses the effects to the NLEB resulting from purposeful and incidental take based on the occurrence
of WNS. Because the project is located within a WNS zone and will include the removal/clearing of trees,
it is subject to the final 4(d) ruling. As previously stated, a review of NCNHP records did not indicate any
known NLEB populations within 2.0 mile of the study area;therefore,the project is eligible to use the
NLEB 4(d) Rule Streamlined Consultation Form to meet regulatory requirements for section 7(a)(2)
compliance 4(d) consultation. The completed NLEB 4(d) Consultation Form was submitted to the
USFWS by the Federal Highway Administration (FHWA) on July 17, 2019.
Bog Turtle
Wildlands determined the project"may affect, not likely to adversely affect"the bog turtle; however, it
is listed due to similarity of appearance and is not subject to Section 7 consultation.
Dwarf-flowered heartleaf and the Scweinitz's sunflower
Wildlands determined the project will have "no effect" on the two listed plant species (dwarf-flowered
heartleaf and the Schweinitz's sunflower).Though the survey was performed outside of the blooming
season for the sunflower, no populations resembling the species were found on-site;therefore,
Wildlands is confident with the determination of"no effect" outside of the blooming season for this
species.
046 Oak Hill Dairy Mitigation Site Categorical Exclusion
DMS#100120 2

To meet regulatory requirements, a scoping letter requesting comment from the USFWS was sent on
June 14, 2019. No response from the USFWS was received within the 45-day response period.
Therefore,the signing of the NLEB 4(d) Rule Streamlined Consultation Form by the FHWA determines
that this project may affect the NLEB, but that any resulting incidental take of the NLEB is not prohibited
by the final 4(d) rule. A FHWA signed 4(d) Consultation Form and the correspondence associated with
this determination are included in the Appendix.
Farmland Protection Policy Act(FPPA)
The FPPA requires that, before taking or approving any federal action that would result in conversion of
farmland,the agency must examine the effects of the action using the criteria set forth in the FPPA, and,
if there are adverse effects, must consider alternatives to lessen them.
Oak Hill Dairy Mitigation Site includes the conversion of prime farmland. As such, Form AD-1006 has
been completed and submitted to the Natural Resources Conservation Service (NRCS).The completed
form and correspondence documenting its submittal is included in the Appendix.
Fish and Wildlife Coordination Act(FWCA)
The FWCA requires consultation with the USFWS and the appropriate state wildlife agency on projects
that alter or modify a water body. Reports and recommendations prepared by these agencies document
project effects on wildlife and identify measures that may be adopted to prevent loss or damage to
wildlife resources.
The Oak Hill Dairy Mitigation Site includes stream and wetland restoration. Wildlands requested
comment on the project from both the USFWS and the North Carolina Wildlife Resources Commission
(NCWRC) on June 14, 2019. No response from the USFWS was received within the 45-day response
period. Therefore,Wildlands assumes USFWS has no comments regarding associated laws and do not
have any information relevant to the project at the current time. NCWRC responded to the scoping
letter on August 7, 2019 that they have no known records of state or federally-listed rare,threatened, or
endangered species within or near the project area. All correspondence with the two agencies is
included in the appendix.
Migratory Bird Treaty Act(MBTA)
The MBTA makes it unlawful for anyone to kill, capture, collect, possess, buy, sell,trade, ship, import, or
export any migratory bird.The indirect killing of birds by destroying their nests and eggs is covered by
the MBTA, so construction in nesting areas during nesting seasons can constitute a taking.
Wildlands requested comment on the Oak Hill Dairy Mitigation Site from the USFWS in regard to
migratory birds on June 14, 2019.The USFWS has not responded at this time. All correspondence with
USFWS is included in the Appendix.

Re: Oak Hill Dairy Mitigation Site
Mr. Paul Wiesner:
The Cherokee Nation (Nation) is in receipt of your correspondence about Oak Hill Dairy
Mitigation Site, and appreciates the opportunity to provide comment upon this project. Please
allow this letter to serve as the Nation's interest in acting as a consulting party to this proposed
project.
The Nation maintains databases and records of cultural,historic, and pre-historic resources in this
area. Our Historic Preservation Office reviewed this project, cross referenced the project's legal
description against our information, and found no instances where this project intersects or adjoins
such resources. Thus, the Nation does not foresee this project imparting impacts to Cherokee
cultural resources at this time.
However, the Nation requests that the North Carolina Depattiuent of Environmental Quality
(NCDEQ)halt all project activities immediately and re-contact our Offices for further consultation
if items of cultural significance are discovered during the course of this project.
Additionally, the Nation requests that NCDEQ conduct appropriate inquiries with other pertinent
Tribal and Historic Preservation Offices regarding historic and prehistoric resources not included
in the Nation's databases or records.
If you require additional information or have any questions,please contact me at your convenience.
Thank you for your time and attention to this matter.

Subject: Request for Project Review and Comments
Oak Hill Dairy Mitigation Site
Gaston County,North Carolina
Dear Ms. Gimbert,
Biologists with the North Carolina Wildlife Resource Commission(NCWRC)received your request to
review and comment on any possible concerns regarding the Oak Hill Dairy Mitigation Site. Biologists
with NCWRC have reviewed the provided documents. Comments are provided in accordance with
provisions of the Fish and Wildlife Coordination Act(48 Stat.401,as amended; 16 U.S.C. 661-667e)and
North Carolina General Statutes(G.S. 113-131 et seq.).
The Oak Hill Dairy Mitigation Site is located southeast of the intersection of Roy Eaker Road and Robert
Road in Cherryville,Gaston County,North Carolina. The site occurs within an existing livestock
pasture/dairy feedlot,agricultural fields,and forested area. The project will provide in-kind mitigation for
unavoidable impacts to streams and wetlands within the Catawba River Basin(HUC 03050102). The
project will restore,enhance,or preserve portions of Oak Hill Creek,its unnamed tributaries,and
wetlands. Two stormwater BMP's are proposed for the project to filter runoff from the dairy feedlot.
We have no known state or federally-listed rare,threatened,or endangered species within or near the
project area. The lack of records from the site does not imply or confirm the absence of federal or state-
listed species. An on-site survey is the only means to determine if the proposed project may impact
federal or state rare,threatened,or endangered species.
Based upon the information provided to NCWRC,it is unlikely that stream and wetland mitigation will
adversely affect any federal or state-listed species. However,we recommend leaving snags and mature
trees or if necessary,remove tees outside the maternity roosting season for bats(May 15—August 15).
We recommend that riparian buffers are as wide as possible,given site constraints and landowner needs.
NCWRC generally recommends a woody buffer of 100 feet on perennial streams to maximize the
benefits of buffers,including bank stability, stream shading,treatment of overland runoff,and wildlife
habitat.

Oak Hill Dairy Mitigation Site
Gaston County
The use of biodegradable and wildlife-friendly sediment and erosion control devices is strongly
recommended. Silt fencing,fiber rolls and/or other products should have loose-weave netting that is
made of natural fiber materials with movable joints between the vertical and horizontal twines. Silt
fencing that has been reinforced with plastic or metal mesh should be avoided as it impedes the
movement of terrestrial wildlife species. Excessive silt and sediment loads can have detrimental effects
on aquatic resources including destruction of spawning habitat,suffocation of eggs,and clogging of gills.
Stream and wetland mitigation projects often improve water quality and aquatic habitat. Establishing
native,forested buffers in riparian areas will help protect water quality,improve aquatic and terrestrial
habitats,and provide a travel corridor for wildlife species. Provided measures are taken to minimize
erosion and sedimentation from construction/restoration activities,we do not anticipate the project to
result in significant adverse impacts to aquatic and terrestrial wildlife resources.
Thank you for the opportunity to provide comments. If I can be of additional assistance,please call(919)

Northern Long-Eared Bat 4(d) Rule Streamlined Consultation Form
Federal agencies should use this form for the optional streamlined consultation framework for the northern long-
eared bat(NLEB). This framework allows federal agencies to rely upon the U.S. Fish and Wildlife Service's
(USFWS)January 5,2016, intra-Service Programmatic Biological Opinion(BO)on the final 4(d)rule for the
NLEB for section 7(a)(2)compliance by: (1)notifying the USFWS that an action agency will use the streamlined
framework; (2)describing the project with sufficient detail to support the required determination; and(3)enabling
the USFWS to track effects and determine if reinitiation of consultation is required per 50 CFR 402.16.
This form is not necessary if an agency determines that a proposed action will have no effect to the NLEB or if
the USFWS has concurred in writing with an agency's determination that a proposed action may affect, but is not
likely to adversely affect the NLEB (i.e.,the standard informal consultation process). Actions that may cause
prohibited incidental take require separate formal consultation.Providing this information does not address
section 7(a)(2)compliance for any other listed species.
Information to Determine 4(d) Rule Compliance: YES NO
1. Does the project occur wholly outside of the WNS Zone'? ❑
2. Have you contacted the appropriate agency to determine if your project is near ® ❑

Project Name: Oak Hill Dairy Mitigation Site
Project Location (include coordinates if known): latitude 35.40305, longitude 81.35226
Basic Project Description (provide narrative below or attach additional information):
The Oak Hill Dairy Mitigation Site is being developed to provide stream and wetland mitigation. Wildlands' approach to the
project involves a multi-tiered approach including preservation,enhancement II,restoration,and wetland re-establishment. In
addition,two stormwater BMPs are proposed for the project to filter runoff from the dairy feedlot.The area surrounding the
streams and channels proposed for stream and wetland mitigation is currently agricultural fields, and extensively impacted by
cattle grazing and crop land.The dairy's primary waste lagoon drains to the proposed easement,and much of the floodplain
has been manipulated and ditched for crop drainage.This project will improve water quality and ecology in this water supply
watershed through cattle exclusion,buffer reforestation,reconnecting streams to the historic floodplain,restoring stream
shape and function,and installation of two agricultural best management practices(BMP)to treat overland flow.
Construction of the stream restoration project will include some tree removal(>3"DBH)—approximately 1.24 acres.

• Preliminary Hydric Soil Investigation dated 1/5/2019 prepared by Soil & Environmental Consultants
Meeting Notes
1. It was noted that the site scored highly on the scoring form. Wildlands that the site was a high priority
site identified within a local watershed plan.
2. The site walk proceeded from downstream to upstream along the mainstem. Wildlands indicated that
the mainstem would be located away from the existing driveway out into the field to support wetland
hydrology(priority 1)with priority 2 segments at the lower end of the reach to transition to the existing
road crossing.
3. Todd/Mac noted that levees are typical along streams in the piedmont with Chewacla soils and
indicated that Wildlands should consider putting a gage in the existing/proposed near stream area to
document water levels and anticipate potential levy formation on the restored stream.

4. Test pits in wetland 1 yielded shallow hydric indicators, particularly off the existing stream levy.
5. Along mainstem Oak Hill Creek Reach 1 (enhancement 2), in response to IRT and DMS comment about
proposed activities being more typical of enhancement 1 level effort,Wildlands indicated that
enhancement 2 credit is being sought because the treatments are non-continuous in this reach. As an
example, it was pointed out that essentially no channel work is proposed at the top of the reach,
including an area with minor erosion into weathered bedrock. Wildlands indicated that the primary
activity proposed in the reach is stabilizing/grading outside meanders. (As an aside, IRT members
encouraged Wildlands to provide workplan in E1/E2 reaches in the future, as was recently provided on
Dynamite Creek, as they found this helpful in defining the specifics of reach treatments).
6. Evidence of historic drain tiles (wooden) were noted in the bank along this same enhancement 2 reach-
entering from the wetland 3 (left) side of the creek. Shawn noted that he'd seen tiles further
downstream as well.
7. Todd indicated that Wildlands should be aware of the potential buffer impacts of the proposed crossing
at the mainstem reach 1/2 break; the crossing is at a skew to match the skew of the sewerline crossing.
8. Todd indicated that upstream portion of Wetland 3 should be gaged to provide evidence of wetland
hydrology.
9. Wildlands would need to prove proposed wetland 2 is relic within area of deeper hydric soils for re-
establishment. Portions of wetland 2 with deeper hydric soils proposed for grading over 6 inches
without new evidence/justification would likely push into wetland creation with a higher mitigation
ratio. Todd and Mac both commented about the existing data and the borings conducted during the
visit pointing to a higher"risk" that hydric soils would not develop and/or that hydrologic criteria could
not be met. It was stated that design data and post-project data will have to support approach and
presented at the mitigation plan stage for IRT review.
10. Wildlands indicated that BMP 2 would be a depression to capture and treat runoff from feeding and
concentrated cattle use area.
11. IRT indicated that JD on UT1B would be important information in validating approach. Wildlands
indicated that UT1B was added to the project to preserve the source of hydrology against future impacts
should it be left out.
12. IRT asked how Wildlands justifies the restoration approach on upper part of UT1 (near UT1A) pointing to
some stable bed and bench features in the upper portion of the reach. Wildlands responded that the
culvert at the head of the reach is perched, and raising the stream at the top of the project, and moving
to a priority 1 as far upstream as possible, is important to the overall project approach.
13. Obvious evidence of cattle in the creek was noted in UT1.
14. Several discrete invasive species infestations were observed throughout the project area (kudzu,
knotweed, bamboo), including privet throughout the project area.
15. The group walked along UT1A which is slated for restoration and was an obvious wallow pit for cattle
and extremely degraded.
16. In summarizing the site visit,the approaches to project were agreed to with the exception of a section of
wetland 2 which is expected to be classified as creation due to the grading depth required to be
completed to reach hydric layers.

APPENDIX 8—Invasive Species Treatment Plan

Appendix 8 Invasive Species Plan
Annual monitoring and semi-annual site visits will be conducted to assess the condition of the finished
project.These site inspections may identify the presence of invasive vegetation. If, during the
monitoring period, invasive species threaten the survivability of planted woody vegetation in an area
that exceeds 1%of the planted easement acreage, the invasive species shall be treated. Smaller areas
may be treated at the discretion of the project engineer and biologist, if deemed in the best interest of
the Site. Generally, the treatment plan shall follow the below guidelines in Table 1 for common invasive
species found in riparian areas; however, the treatment may be changed based on the professional
judgement of the project engineer and biologist. For invasive species not listed in the below table that
threaten the survivability of the planted woody vegetation, Wildlands shall notify DMS of the invasive
species observed and the plan for treatment prior to treating the species. All invasive species treatment
will be reported in the following year's monitoring plan.

Care should be taken to bag and remove the plants, including mature fruits to prevent re-
establishment. Large infestations of L.japonica will usually require a combination of cut
Honeysuckle stump and foliar herbicide treatments.Where vines have grown into the tree canopy,cut
each stem as close to the ground as possible.Treat the freshly cut surface of the rooted
(Lonicera stem with a 25 percent solution of glyphosate or triclopyr. Remove the twining vines to
japonica)
prevent them from girdling and killing desirable vegetation.Groundcovers of L.japonica
can be treated with a foliar solution of 2 percent glyphosate or triclopyr plus a 0.5 percent
non-ionic surfactant to thoroughly wet all the leaves.
Thoroughly wet all leaves with one of the following herbicides in water with a surfactant: a
glyphosate herbicide as a 3-percent solution (12 ounces per 3-gallon mix) in the late fall or
Chinese Privet early winter when safety to surrounding vegetation is desired,or elsewhere,Arsenal AC*
(Ligustrum
as a 1-percent solution (4 ounces per 3-gallon mix). Backpack mist blowers can broadcast
sinense) glyphosate as a 3-percent solution (12 ounces per 3-gallon mix)or Escort XP*at 1 ounce
per acre (0.2 dry ounces per 3-gallon mix and 10 gallons per acre)during winter for safety
Oak Hill Dairy Mitigation Site Appendix 8
DMS ID No. 100120 Page 1

Invasive Species Recommended Removal Technique
to dormant hardwoods.Summer applications of glyphosate may not be as effective as
other times and require a higher percent solution.The best time for Arsenal AC*and Escort
XP* is summer to fall. For stems too tall for foliar sprays and when safety to surrounding
vegetation is desired,apply a basal spray of Garton 4 as a 20-percent solution (5 pints per
3-gallon mix) in a labeled basal oil product,vegetable oil or mineral oil with a penetrant,or
fuel oil or diesel fuel (where permitted); or undiluted Pathfinder II. Elsewhere,apply
Stalker*as a 6-to 9-percent solution (1.5 to 2 pints per 3-gallon mix) in a labeled basal oil
product,vegetable oil or mineral oil with a penetrant,or fuel oil or diesel fuel (where
permitted)to young bark as a basal spray making certain to treat all stems in a clump; or
cut and immediately treat the stump tops with Arsenal AC*as a 5-percent solution (20
ounces per 3-gallon mix)or Velpar L*as a 10-percent solution in water(1 quart per 3-
gallon mix)with a surfactant.When safety to surrounding vegetation is desired,
immediately treat stump tops and sides with Garlon 3A or with a glyphosate herbicide as a
20-percent solution (5 pints per 3-gallon mix) in water with a surfactant.ORTHO Brush-B-
Gon and Enforcer Brush Killer are effective undiluted for treating cut-stumps and available
in retail garden stores(safe to surrounding plants). For large stems, make stem injections
using Arsenal AC*or when safety to surrounding vegetation is desired,Garlon 3A or a
glyphosate herbicide using dilutions and cut-spacings specified on the herbicide label
(anytime except March and April).An EZ-Ject tree injector can help to reach the lower part
of the main stem;otherwise, every branching trunk must be hack-and-squirt injected.
Small patches of P. montana that are not well-established can usually be eliminated by
persistent weeding, mowing,or grazing during the growing season.The spread of a well-
established infestation of P.montana can be controlled the same way, but cutting will
typically not kill the roots of larger plants. For vines in tree canopies,cut the vines near the
ground and apply a 50 percent solution of triclopyr to the stumps.This procedure remains
effective at lower temperatures as long as the ground is not frozen. Large infestations can
be effectively controlled with a foliar solution of 2 to 3 percent glyphosate or triclopyr plus
a 0.5 percent non-ionic surfactant to thoroughly wet all leaves.The ambient air
Kudzu temperature should be above 65 degrees Fahrenheit.After the above ground vegetation is
(Pueraria controlled and it is possible to dig and cut into the central root crown,apply a 50 percent
montana) solution of glyphosate or triclopyr to the wound.The most successful chemical control of P.
montana can be achieved with a foliar solution of 0.75 percent clopyralid plus a 0.5 percent
non-ionic surfactant. Monitor all treatments in subsequent years for re-sprouting.
Thoroughly wet all leaves(until runoff)with one of the following herbicides in water with a
surfactant(July to October for successive years): Garlon 3A or Garlon 4 as a 3-to 5-percent
solution (12 to 20 ounces per 3-gallon mix)or a glyphosate herbicide as a 4-percent
English Ivy solution (1 pint per 3-gallon mix). Use a string trimmer to reduce growth layers and injure
(Hedera helix) leaves for improved herbicide uptake.Cut large vines and apply these herbicides to cut
surfaces.Or apply basal sprays of Garlon 4 as a 20-percent solution in a labeled basal oil
product,vegetable oil, kerosene,or diesel fuel (where permitted) (5 pints per 3-gallon
mix); or apply undiluted Pathfinder II to large vines,avoiding the bark of desirable trees.
Johnson Grass Recommended control procedures:
(Sorghum Thoroughly wet all leaves with one of the following herbicides in water with a surfactant
halepense) (June to October with multiple applications applied to regrowth).
Oak Hill Dairy Mitigation Site Appendix 8
DMS ID No. 100120 Page 2

Invasive Species Recommended Removal Technique
• Recommendation for mature grass control:apply Outrider* as a broadcast spray at 0.75
to 2 ounces per acre(0.2 to 0.6 dry ounce per 3-gallon mix) plus a nonionic surfactant to
actively growing Johnsongrass. For handheld and high-volume sprayers,apply 1 ounce of
Outrider per 100 gallons of water plus a nonionic surfactant at 0.25 percent.Outrider is a
selective herbicide that can be applied over the top of certain other grasses to kill
Johnsongrass,or apply Plateau as a 0.25-percent solution (1 ounce per 3-gallon mix)when
plants are 18 to 24 inches(45 to 60 cm)tall or larger.
• Recommendation for seedling control:apply Journey as a 0.3-percent solution (1.2
ounces per 3-gallon mix) before Johnsongrass sprouts and when desirable species are
dormant or apply a glyphosate herbicide as a 2-percent solution (8 ounces per 3-gallon
mix)directed at the infestation.
Foliar applications—Thoroughly wet all leaves with one of the following herbicides in water
Asian Spiderwort with a surfactant:2-3%aquatic labeled glyphosate.
(Murdannia kiesk) Do not remove mechanically.Spiderwort spreads readily in disturbed areas through
fragmentation and seed dispersal.

APPENDIX 10—Maintenance Plan

Appendix 10 Maintenance Plan
The site shall be visited semi-annually and a physical inspection of the site shall be conducted a
minimum of once per year throughout the post-construction monitoring period until performance
standards are met.These site inspections may identify site components and features that require
routine maintenance. Routine maintenance should be expected most often in the first two years
following site construction and may include the following:
Table 1. Maintenance Plan—Oak Hill Dairy Mitigation Site
Component/
Maintenance through project close-out
Feature
Routine channel maintenance and repair activities may include chinking of in-stream
structures to prevent piping,securing of loose coir matting, and supplemental installations
of live stakes and other target vegetation along the channel—these shall be conducted
where success criteria are threatened or at the discretion of the Designer.Areas where
Stream storm water and floodplain flows intercept the channel may also require maintenance to
prevent bank failures and head-cutting. Beaver activity will be monitored and beaver dams
on project streams will typically be removed,at the discretion of the Designer,during the
monitoring period to allow for bank stabilization and stream development outside of this
type of influence.
Routine wetland maintenance and repair activities may include supplemental installations of
Wetlands target vegetation within the wetland.Areas where storm water and floodplain flows
intercept the wetland may also require maintenance to prevent scour that adversely and
persistently threatens wetland habitat or function.
Vegetation shall be maintained to ensure the health and vigor of the targeted community.
Routine vegetation maintenance and repair activities may include supplemental planting,
Vegetation pruning, mulching,and fertilizing. Exotic invasive plant species requiring treatment per the
Invasive Species Treatment Plan (Appendix 8)shall be treated in accordance with that plan
and with NC Department of Agriculture(NCDA) rules and regulations.
Site boundaries shall be identified in the field to ensure clear distinction between the
mitigation site and adjacent properties. Boundaries may be identified by fence, marker,
Site boundary bollard, post,tree-blazing,or other means as allowed by site conditions and/or conservation
easement. Boundary markers disturbed,damaged,or destroyed will be repaired and/or
replaced on an as-needed basis.

APPENDIX 13—Credit Release Schedule

Appendix 13 - Credit Release Schedule and Supporting Information
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
Department of the Army(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 as
follows:
Table A:Credit Release Schedule—Stream Credits—Oak Hill Dairy Mitigation Site

3 1 Year 1 monitoring report demonstrates that channels are stable and 10% 40%
interim performance standards have been met
4 2 Year 2 monitoring report demonstrates that channels are stable and 10% 50%
interim performance standards have been met
5 3 Year 3 monitoring report demonstrates that channels are stable and 10% 60%
interim performance standards have been met
6 4* Year 4 monitoring report demonstrates that channels are stable and 5% 65%
interim performance standards have been met (75%**)
7 5 Year 5 monitoring report demonstrates that channels are stable and 10% 75%
interim performance standards have been met (85%**)
8 6* Year 6 monitoring report demonstrates that channels are stable and 5% 80%
interim performance standards have been met (90%**)
9 7 Year 7 monitoring report demonstrates that channels are stable and 10% 90%
interim performance standards have been met (100%**)
*Vegetation data may not be required with monitoring reports submitted during these monitoring years unless
otherwise required by the Mitigation Plan or directed by the NCIRT.
**10%reserve of credits to be held back until the bankfull event performance standard has been met

*Vegetation data may not be required with monitoring reports submitted during these monitoring years unless
otherwise required by the Mitigation Plan or directed by the NCIRT.
1.1 Initial Allocation of Released Credits
For this NCDMS project, no initial release of credits is provided. To account for this, the 15%credit
release typically associated with the site establishment is held until completion of all initial physical and
biological improvements made pursuant to the Mitigation Plan. In order for NCDMS to receive the 30%
release (shown in Tables A and B as Milestone 2), they must comply with the credit release
requirements stated in Section IV(I)(3) of the approved NCDMS instrument.
1.2 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.
The following conditions apply to credit release schedules:
a. A reserve of 10%of site's total stream credits will be release after four bankfull events have
occurred, in separate years, provided the channel is stable and all other performance standards
are met. In the event that less than four bankfull events occur during the monitoring period,
release of these reserve credits is at the discretion of the NCIRT.
b. After the second milestone, the credit releases are scheduled to occur on an annual basis,
assuming that the annual monitoring report has been provided to the USACE in accordance with
Section IV(General Monitoring Requirements) of this document, and that the monitoring report
demonstrates that interim performance standards are being met and that no other concerns
have been identified on-site during the visual monitoring. All credit releases require written
approval from the USACE.
c. The credits associated with the final credit release milestone will be released only upon a
determination by the USACE, in consultation with the NCIRT, of functional success as defined in
the Mitigation Plan.
As projects approach milestones associated with credit release, the DMS 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.
