1.0 Project Introduction
The Tar River Headwaters Wetland Restoration Site (TRHWR) is a full -delivery wetland mitigation
project located in eastern Person County, between Roxboro and Oxford, North Carolina, within the
Piedmont Physiographic Province (Figure 1). The site comprises 9.98 acres which includes a 1.06 acre
connector area, most of which is drained and degraded wetlands or former wetlands (see photo below),
with hydric soil indicators. This includes the 1 -acre 570 -foot connector corridor. The remaining areas
include non -hydric soils, drainage ditches, and a riparian corridor along an intermittent stream
connecting the TRHWR site to the adjacent Tar River Headwaters Riparian Buffer and Nutrient Offset
Mitigation Bank project. Both projects are designed and implemented by Mogensen Mitigation, Inc.
(MMI), and are located on a 228 -acre farm owned by Roy and Joyce Huff, in the Tar -Pamlico River
Basin 12 -digit HUC # 03020101-0102. The Huff Farm property is located at 333 Bunnie Huff Road,
Oxford NC 27565. The access road into the TRHWR site is at Latitude = 36.3913, Longitude = -
78.8171.

Final Mitigation Plan -- Mogensen Mitigation Inc.
The TRHWR site was cleared and ditched for pasture use in the 1940s according to the owner, and is
currently used for grazing cattle. The project involves plugging drainage ditches to restore wetland
hydrology, fencing to exclude livestock, and planting native trees and shrubs to restore a Headwater
Forest wetland ecosystem similar to what occurred prior to site clearing and drainage. The remnant
mature trees left for shade, hydrophytic groundcover plants mixed among the pasture grasses, and plant
species recorded in adjacent forests (on the same soil mapping unit) provide data for the planting plan.
The proposed work will restore approximately 7.65 acres of headwater riparian wetland (6.53 acres
reestablishment plus 1.12 acres rehabilitation) and will generate an estimated 7.28 or more riparian
wetland mitigation credits (RWMC), exceeding the 5.0 RWMC requested by the NC Division of
Mitigation Services (DMS) in RFP # 16-006476. Approximately 1.27 acres with non -hydric soils in
the southeast corner of the mitigation site will also be reforested, and a 100 -foot wide by 570 -ft long
riparian corridor (1.06 acre) extending southeastward along the ditch will connect the TRHWR site to
MMI's adjacent stream restoration and nutrient buffer bank project to the south. Total acreage of the
wetland mitigation site and riparian connector is 9.98 acres.
The proposed wetland restoration and cattle exclusion will reduce soil erosion and nutrient -enriched
runoff from adjacent pasture and cropland within its watershed, and help retain agricultural chemicals
used on these lands. Erosion will be significantly reduced by buffering with native tree plantings. It is
expected to improve water quality and habitat in the receiving tributary and reduce fine sediment
loading which will enhance the overall watershed particularly in the adjacent stream and nutrient
mitigation bank.
Directions to TRHWR site: From Raleigh, follow NC -50 north to Creedmoor, NC. Continue north
and west on NC -56, Brodgen Rd, Old Rte -75, Culbreth Rd, NC -158, and Old Roxboro Rd. At the
Granville/Person County line Old Roxboro Rd becomes Denny Store Rd, and 1.5 miles past the county
line turn right (north) on Bunnie Huff Road. Go 0.4 mile to a gravel driveway on the left (just past the
Huffs' house and sign) and follow it through the farm gate and across the creek to the TRHWR site.
2.0 Watershed Approach and Site Selection
The TRHWR site is in the northern portion of the uppermost local watershed of the Tar -Pamlico River
basin, 12 -digit HUC # 03020101-0102. This DMS Targeted Local Watershed (TLW) is the headwaters
for the City of Oxford's water supply (rated as Class WS -IV; NSW) and also one of the most
ecologically significant stream ecosystems in the NC Piedmont, with high biodiversity and several rare
and endemic aquatic species (Figure 2).
The location and scope of this project enables it to address multiple Restoration Goals outlined in the
Tar -Pamlico River Basin Restoration Priorities Report (2010). One such goal specific to this project's
Catalogue Unit is to "protect, augment, and connect Natural Heritage Areas and other conservation
lands." The TRHWR site is approximately 570 feet north of MMI's existing stream restoration and
nutrient buffer bank project (connected by riparian corridor), and is close to the Denny Store Gabbro
Tar River Headwaters Wetland Restoration Site Page 12
Final Mitigation Plan -- Mogensen Mitigation Inc.
Forest Significant Natural Heritage Area (SNHA) designated by NC Natural Heritage Program (NHP),
located 1,000 feet to the north and east of the TRHWR site. The southeastern portion of this SNHA is
on the Huff Farm property and abutting the north end of the stream and buffer bank project.

Figure 2. NHP Significant Natural Heritage Areas (SNHA) near the TRHWR site and Huff Farm. Stream segments
colored brown (Upper Tar River Aquatic Habitat) are known to support rare species.
Downstream of the Huff Farm property, the Upper Tar River Aquatic Habitat SNHA supports 15 rare
species of stream -dwelling animals (mussels, fishes, crayfishes, and salamanders) known to occur
within eight miles downstream of the project on the Triple Springs and Moriah USGS Quadrangles
(NHP database, 2015). This riverine SNHA begins 1.2 miles downstream of the Huff Farm property,
and 1.5 miles below the TRHWR site. NC's most viable population of the federally endangered dwarf
wedgemussel occurs within this SNHA in the Tar River between the Person/Granville County line and
US Highway 15 bridge south of Oxford.
Restoration Priorities for the Upper Tar River Targeted Local Watershed (TLW) include projects that
"address agricultural inputs (nutrients and sediment) and those that reestablish woody buffers". This
project directly addresses both of those listed priorities through the rehabilitation and re-establishment
of native wetlands, the exclusion of cattle, and reforestation and protection of a riparian corridor

between two mitigation projects. The river and tributaries in Person County are not designated
impaired (303d listed) but DEQ Biological Assessment Branch staff noted excessive sediment, channel
instability, and nutrient enrichment impacts in several streams in the upper Tar River watershed
(DWQ, 2007). MMI staff observed these agricultural impact symptoms in the intermittent stream
reach immediately downslope from the proposed wetland restoration area and in the perennial stream
just below that reach, in the Tar River Headwaters Riparian Buffer and Nutrient Offset Mitigation
Bank project area. By restoring and protecting a headwater wetland this project will help improve
downstream water quality and thereby support the overall watershed planning framework.
3.0 Existing Conditions (Baseline)
3.1 Watershed Processes & Landscape Characteristics
The project is located in the Carolina Slate Belt region of the Piedmont Physiographic Province.
Elevations on the project site range from approximately 582 feet above mean sea level (MSL) at the
northern edge to 570 feet at the southern edge of the wetland restoration area. Valley slope from north
to south was calculated at 1.2 percent (12 feet in height / 978 feet in length), and lateral slopes on
either side, between 1 and 2 percent. The connector channel drops another 6 feet (from 570 feet to 564
feet) along its 570 -foot course from the wetland restoration area to its confluence with the larger
stream in the buffer bank project (Figures 3 and 4).
The US Department of Agriculture's 1995 Soil Survey of Person County maps the project area as
Orange loam (OnA), but this mapping unit was later revised to Iredell loam (Ir) in the online Web Soil
Survey. This extensive soil map unit (more than 2 square miles) continues eastward into Granville
County (Figure 3). Onsite analysis by Licensed Soil Scientist Heather Smith of Ecological
Engineering, Inc. determined that the majority of the THRWR area soils, with exception of the
southeast corner, are unmapped hydric inclusions of Wehadkee soil (Table 1 and Appendix 9) or a wet
phase of Iredell soil (Mac Haupt, NCDWR comments). These areas have dense clayey subsoil with
slow infiltration, and can accumulate "perched" saturation or ponding especially in winter when
evapotranspiration is low.
The 1.27 -acre non -hydric area in the southeast corner of the project site exhibited insufficient
redoximorphic features to meet the hydric soil criteria and is most likely the mapped Iredell soil type.
It is unclear however, whether this area may have once been hydric. Redoximorphic features may have
weakened due to oxidation over the 70 years since it was ditched and drained. Soils along the
connector corridor between the proposed wetland restoration area and the existing stream and buffer
bank project downslope are mapped as Chewacla loam. The lower 250 -foot segment of this ditched
channel (below the existing vehicle crossing) was field -designated by DEQ Division of Water
Resources (DWR) as a stream subject to Tar -Pamlico Buffer rules in June 2013. US Army Corps of
Tar River Headwaters Wetland Restoration Site Page 14
Final Mitigation Plan -- Mogensen Mitigation Inc.
Engineers (USAGE) agent Eric Alsmeyer confirmed on 06 July 2016 that the ditch segment within the
TRHWR area is not a jurisdictional water subject to Section 404-401 regulation.

3.2 Land Use and Land Cover
The project site is presently a cattle pasture dominated by non-native forage grasses interspersed with
native and non-native herbs. Several large trees were left standing to provide shade for the cattle when
the site was cleared in the 1940s, and a few younger trees have sprouted and survived. Existing trees
include seven of the rare swamp white oak (Quercus bicolor), plus several willow oak (Quercus
phellos), silver maple (Acer saccharinum), boxelder (Acer negundo), sweetgum (Liquidambar
styraciflua), black gum (Nyssa sylvatica) and loblolly pine (Pinus taeda). Hydrophytic herbs (FACW
and OBL) are present among the pasture grasses including swamp milkweed (Asclepias incarnata),
Tar River Headwaters Wetland Restoration Site Page 18
Final Mitigation Plan -- Mogensen Mitigation Inc.
rushes (Juncus spp), spikerush (Eleocharis spp), woolgrass bulrush (Scirpus cyperinus), New York
ironweed (Vernonia novaboracensis), buttonweed (Diodia virginiana), various sedges (Carex,
Cyperus, Rhynchospora spp), and fall sneezeweed (Helenium autumnale). Other than pasture grasses
(mainly fescue) and some limited patches of Japanese honeysuckle and multiflora rose are also present.
Iinvasive weeds do not appear to be a major problem on the project site.
The Denny Store Gabbro Forest, a designated SNHA (privately owned and unprotected to our
knowledge) lies to the north and east of the TRHWR site, and also borders the adjacent stream and
buffer mitigation bank easement (Figure 5). This natural area "contains one of the best quality and
most extensive hardwood forests over high pH soils in the northern Piedmont, with excellent examples
of Basic Oak -Hickory Forest, Basic Mesic Forest on Flats, Upland Depression Swamp Forest, and
Mesic Hardpan Forest" (LeGrand, 2007, Person County Natural Areas Inventory). Rare species
recorded on this site include swamp white oak, Chinquapin oak (Quercus muehlenbergii), glade wild
quinine (Parthenium auriculatum), and Lewis's heartleaf (Hexastylis lewisii). It is likely that some of
these other rare species (in addition to Swamp White Oak) may have occurred on the project site and
could be reintroduced, or may recolonize on their own from the nearby natural area.
The TRHWR site has been in continuous agricultural use for about 70 years, and land use in the surrounding
area has changed little over the past several decades. The nearest municipalities (Roxboro, Oxford, and
Butner) are 8 to 10 miles away, and there are no plans to extend public water
and sewer service to the Denny Store vicinity in the foreseeable future. The rate of urban development
in the project vicinity is likely to remain very low for decades. Most of the project site's watershed is
on the Huff Farm property, where land use and land cover are likely to remain similar to current
conditions. Periodic harvest of timber may occur in the project watershed and adjacent forest lands,
but this activity should have little effect on the project site.
3.3 Watershed Disturbance and Response
Based on information obtained from the landowner, the shallow drainage ditches were constructed in
the 1940s to dewater the wetland sufficiently for pasture use. An east -west ditch across the northern
perimeter of the site intercepts overland flows from the north, and channels the water into a south -
flowing main ditch that discharges into a natural intermittent stream downslope of the proposed
restoration area. Two additional lateral ditches, one on each side of the main ditch, join the main ditch
about 700 feet south of the ditch at the northern edge. Because the water table is perched over dense
clay and shallow bedrock, these shallow ditches can effectively drain water off a much wider area than
if the soils were more permeable and drainage not limited by a shallow aquitard. Seventy years of
cattle grazing may have further compacted the soils on the site.
It is unclear how far upslope the intermittent receiving stream may have extended prior to clearing and
ditching. The Soil Survey of Person County shows it extending through the TRHWR site and about
500 feet northward beyond the east -west -ditch, almost to the powerline right-of-way (refer back to
Figure 5). However, this map was prepared several decades after clearing and ditching, and the natural
Tar River Headwaters Wetland Restoration Site Page 19
Final Mitigation Plan -- Mogensen Mitigation Inc.
stream versus ditch transition would have been indistinguishable. The areas mapped as "OnA" soils to
the north and west of the TRHWR site have few stream channels depicted. Based on MMI's analysis
and observations in the Denny Store Gabbro Forest to the north (reference site), it is likely that surface
runoff from the TRHWR site prior to ditching flowed southward via multiple indistinct braided
channels, seeps and pools, rather than a discrete stream.
The intermittent stream downslope of the proposed restoration area (lower segment of the TRHWR
connector corridor) has mostly forested banks but is accessible to cattle and thus subject to hoof -shear.
It is unclear to what extent this stream's entrenched condition and bank erosion is due to
channelization decades ago, versus ongoing erosion due to cattle damage. The lowermost 50 -foot
reach of this stream was fenced to exclude cattle (in 2015) before it joins the perennial stream.
4.0 Functional Uplift Potential
The TRHWR site provides an excellent opportunity for wetland restoration. The majority of the site
has redoximorphic features indicating hydric soils, and groundwater monitoring from February to July
2016 (a period with higher than average rainfall) indicates that most of the site has less than 20
consecutive days of shallow saturation (water table within 12 inches of ground surface) except in the
existing wetlands (Figure 6, blue areas). The site was cleared and ditched in the 1940s, or possibly
earlier, and has been used as cattle pasture for many decades. The native hardwood vegetation is sparse
(about a dozen scattered mature oaks, maple, hickory and ash trees remain) and the site's ability to
infiltrate rainfall, filter nutrients and store base flow is impaired. The small watershed draining to the
site (mostly on the Huff property) comprises woodland, corn fields, and a powerline right-of-way; no
buildings or impervious surface exists in this catchment, and no development is planned. The crop
fields, powerline right-of-way, and adjacent pasture areas beside the TRHWR site will likely remain
non -forested.

Figure 6. Existing Conditions and Proposed Project Assets: existing and drained wetlands to be restored, non -
wetlands, ditches to be plugged, and groundwater gauges, Tar River Headwaters Wetland Restoration Site. See also
Figure 8 for proposed relocation of groundwater gauges for post -construction monitoring.
Cattle fencing, aerating, ditch plugging and reforestation should be effective at improving infiltration,
increasing nutrient uptake by plants and soil microbes, and reducing runoff of eroded soils, excessive
nutrients and fecal bacteria into the receiving ditch and thus into the Tar River tributary a few hundred
feet downstream. With increased water -holding capacity due to the ditch plugs, stream temperature is
expected to fluctuate less widely due to the improved infiltration and shading effects once the trees
grow large enough. Increased shallow ponding in depressions in the restored wetland will provide
breeding habitat for amphibians, dragonflies, and other wildlife that use vernal pool habitats.
The 1.27 -acre area in the southern part of the restoration area that currently lacks sufficient
redoximorphic features to be considered "hydric soil" in 2015 will also become wetter, and might
achieve sufficient hydrology to become part of the wetland. It is unclear whether this area may have
once been hydric, but redoximorphic features have weakened due to oxidation over the 70 years since
it was ditched, or whether it was non -hydric prior to drainage. Since no wetland credit is sought for
this this area; if it does meet wetland hydrology criteria at the end of the monitoring period, it will be a
non -credited "bonus" wetland area.
Tar River Headwaters Wetland Restoration Site Page 111
Final Mitigation Plan -- Mogensen Mitigation Inc.
The connector area between the proposed wetland restoration area and the nutrient and buffer bank
(below the existing vehicle crossing) will be stabilized with tree plantings. No geomorphic
improvements are proposed.
The intermittent stream reach from the vehicle crossing downstream to the buffer bank project
easement is incised (ditched) but has adequate woody root density along the banks. Simply fencing
out the cattle and planting a buffer should provide adequate uplift for this short reach. No geomorphic
improvements are proposed for this reach.
The proximity of the TRHWR site to the Denny Store Gabbro Forest SNHA and presence of rare
species onsite (see section 3.1.2 above) enhances the project's ecological uplift potential. Existing
mature forests within this SNHA are located about 1,000 feet to the north and east of the site and
MMI's adjacent Tar River Headwaters Riparian Buffer and Nutrient Offset Mitigation Bank project
(planted in Dec 2015) will provide an additional 18 -acre bridge between the SNHA area and the
TRHWR area. In addition to the rare Swamp White Oaks already on site, several other state -listed rare
plant species known to occur in the adjacent SNHA may colonize the two restored project easements.
Also, since the Upper Tar River Aquatic Habitat SNHA begins just 1.2 miles downstream of the Huff
Farm property, this pair of projects has high potential to benefit the 15 species of protected stream -
dwelling animals (one federally endangered and 14 federal FSC or state -protected) known to occur in
that SNHA.
Constraints on functional uplift are relatively minimal for this project. The watershed does include
some row -crop land and a powerline right-of-way, but no other existing or planned utilities or
development. The existing farm vehicle crossing on the ditch, midway between the wetland project
area and the buffer bank project, will remain unfenced and is not included in the conservation
easement. The FEMA -regulated floodplain along the perennial stream begins about 5,000 feet
downstream of the Huff Farm property (Person County GIS); no FEMA flood -prone lands will be
affected. No hydrologic trespass issues will occur since the site receives runoff from the land to the
north and west. There is a perimeter ditch that will remain along the northern edge of the site. The flow
regime to the areas south and east will not change. In addition, there are no currently or planned
development threats nearby. Any increased ponding generated as a result of implementation will be
entirely within the conservation easement. There is adequate access across the site for construction and
planting crews and required equipment.
No adverse impacts to federally listed species or cultural resources will occur., Attached concurrence
letters from US Fish and Wildlife Service (FWS) and NC State Historic Preservation Office (SHPO)
are provided in the Appendix. Historical environmental site assessment data was obtained from
Environmental Data Resources, Inc. (EDR) to evaluate the potential for on-site or nearby soil and
water contamination. The project site is not listed in any of the databases searched by EDR, and there
Tar River Headwaters Wetland Restoration Site Page 112

are no federal or state records of "recognized environmental conditions" within a one -mile radius of
the project site.
5.0 Mitigation Project Goals and Objectives
The goal of this project is to restore a Headwater Forest wetland community that was cleared, drained
and converted to pasture in the 1940s (according to the landowner). The site topography and presence
of remnant mature swamp white oak and laurel oak trees on the site suggest that the original plant
community may have been Upland Depression Swamp Forest, Piedmont Headwater Stream Forest
(Hardpan Subtype), or some intermediate between those types (Schafale and Weakley 1990; Schafale
2012). These headwater wetlands typically have a shorter and more fluctuating hydro -period than
alluvial wetlands along larger streams do, and rely more on rainwater ponding and surface runoff
rather than groundwater seepage or over -bank flooding (Schafale 2012). A similar natural forest
(Denny Store Gabbro Forest) documented by NHP located to the north and east of the site will be used
as a reference wetland for hydrologic comparison and vegetation planning. The project will
complement MMI's ongoing riparian buffer and stream restoration project along the adjacent stream
on the Huff Farm property. Specific project GOALS and corresponding OBJECTIVES include:
GOALS:
• Restore the natural jurisdictional wetland hydro -period to five or more acres of forested
wetland within a nine -acre site;
• Restore forested wetland habitat and improve habitat connectivity between Denny Store
Gabbro Forest (NHP Natural Heritage Area) to the north and the Tar River tributaries;
• Buffer storm water runoff from fecal and other cattle -related pollutants.
OBJECTIVES:
• Plug existing ditches and create sheet flows throughout the site. Aerate soils to reduce
compaction, improve infiltration, and create micro -topography to retain surface flows;
• Preserve the remnant mature Swamp White Oaks (a regionally rare species) for seed source.
Plant appropriate native hardwood trees at a sufficient frequency to establish a diverse
bottomland wetland forest. Treat and/or remove invasive species which may cause problems
for site restoration, including Chinese privet and multi -flora rose;
• Install fencing to exclude cattle and establish a conservation easement to provide permanent
protection on the site.

6.0 Design Approach and Mitigation Work Plan
6.1 Conceptual Approach
The project involves 7.65 acres of wetland restoration and 1.27 acres of reforestation to non -wetland
areas. Existing on-site ditches appear to be effectively draining surface water from the site during the
growing season. Although the ditches are shallow, their drainage effect is efficient because this
peculiar type of headwater wetland relies on dense clay and/or shallow bedrock to maintain "perched"
wetland hydrology. Observations by the property owner that the existing field remains wet for
prolonged periods during winter suggests that an appropriate growing season hydrology can be
reestablished by ditch plugging. The NHP "Classification of the Natural Communities of North
Carolina" by Schafale & Weakley (1990) describes Forested Headwater Wetlands as typically situated
in poorly drained broad upland flats with seasonal or intermittent saturation, with stable climax forest
communities maintained by their hydro -period.
The overall work approach includes plugging the existing ditches (central north -south ditch and two
lateral ditches) with native clay excavated from the surrounding areas. Existing mature vegetation will
be left intact and the entire project area will be planted with native woody species, fenced, and
protected in perpetuity.
6.2 Wetland Design
This project involves both components (re-establishment and rehabilitation) of the restoration category
for wetland mitigation credit generation. The re-establishment portions of the project are no longer
functioning as jurisdictional wetlands while the rehabilitation areas are functioning at a lower capacity
due to impacts by cattle, altered vegetation and altered hydrology. Eleven groundwater gauges were
installed throughout the project site to monitor pre -restoration groundwater levels and one was
installed in a reference wetland approximately 1,500 linear feet to the northeast (photo in Appendix
2B). Data from these gauges (March to July 2016) were used to distinguish the boundaries between
the re-establishment and rehabilitation acreages as approved by the USACE (Jurisdictional
Determination letter attached).
Based on LIDAR topographic mapping (from NCDOT LIDAR Contours) the watershed draining to
the wetland restoration site is approximately 20 acres with an average slope of 1-2%. The relatively
flat topography in this area makes watershed boundaries difficult to discern, and subsurface geologic
and soil features may divert flow in ways not apparent based on ground surface topography. This
watershed is undeveloped, containing natural hardwood forest, planted pines, cropland, pasture, and a
powerline. The only man-made structures in the watershed are two powerline towers. The dense soil
in the TRHWR area is a natural feature of Wehadkee soils, but long-term pasture use may have
compacted it further. Hydrology on the site is from direct precipitation and surface runoff during large
storm events from the small watershed, mostly to the north.
Tar River Headwaters Wetland Restoration Site Page 114
Final Mitigation Plan -- Mogensen Mitigation Inc.
The main drainage ditch flows southward through the TRHWR site, with roughly 80% of the easement
area located west of the ditch and 20% east of the ditch. A perpendicular ditch runs east -west across
the northern perimeter of the site, forming a T-shape with the main ditch. The perimeter ditch collects
surface flows from the upstream watershed area. Two additional lateral ditches (one to the east, one to
the west) join the main ditch about 700 feet south of the "T" at the northern edge. All of these
drainage ditches are shallow, primarily intended to channel surface runoff and shallow sub -surface
flow, rather than deeper groundwater. Bedrock and/or hard clay was observed between 15 and 40
inches deep over most of the TRHWR site, supporting a perched seasonal water table. The main ditch
becomes an intermittent stream (as determined by DWR in June 2013) about 250 feet southeast of the
site
6.3 Hydroperiod justification
The hydrology of the existing on-site wetlands is affected mainly by precipitation, surface water run-
off from the contributing watershed, and the presence of an impervious clay layer, creating a perched
water table. The existing hydrologic regime at the site is altered due to surface water removal via a
main north -south ditch and two small lateral ditches. These ditches are not at a depth sufficient to
affect groundwater but serve to quickly remove runoff from the contributing watershed. A water
budget was calculated to determine the volume of water at the TRHWR pre and post wetland
restoration. In order to calculate the water budget, the following assumptions were made:
• The precipitation amount and distribution throughout the year will be constant pre- and post -
restoration.
• Surface water runoff from the contributing watershed is currently leaving TRHWR through the
main north -south ditch.
• Surface water runoff from the contributing watershed post restoration will remain on-site.
• Surface water runoff from TRHWR will be reduced post restoration due to the establishment of
forest -type vegetation and the plugging of the on-site ditches.
• The groundwater inflow and outflow will be constant pre and post restoration.
• Evapotranspiration of the contributing watershed is constant pre -and post -restoration.
• Evapotranspiration of TRHWR is greater post restoration due to the establishment of forested -
type vegetation instead of the current pasture land use.
• Inflow to the TRHWR site is based on direct precipitation plus runoff entering the site from the
north and northwest portion (20 acres) of the overall watershed (Figure 4). Inflow from the
east and southwest portions of the watershed may also contribute to groundwater hydrology on
the site, but the contributing drainage to those areas is not as readily directed into a ditch for
quick off-site conveyance and were not included in the inflow calculations.
The water budget (Appendix 2) indicated there would be an additional 467,000 cubic feet of water held
on-site for the TTHWR post restoration, which is equivalent to an additional 14.4 inches of water on
the site yearly or an additional 1-1.5 inches of water per month across the site, depending on
precipitation. The additional volume of water will infiltrate through the soil profile and result in
Tar River Headwaters Wetland Restoration Site Page 115
Final Mitigation Plan -- Mogensen Mitigation Inc.
increased hydroperiods post -restoration activities. Ancillary benefits from this project that include
increased organic matter and reduced rainfall impact from herbaceous growth, and development of soil
structure and biology through reduction of animal compaction may further improve soil water holding
capacity and soil infiltration rates, benefitting hydrology.
The TRHWR currently has 11 gauges that monitored pre -restoration groundwater levels from April to
June 2016. Four of these gauges (A, E, H, & J) are located within the proposed rehabilitation areas,
deemed by the USACE as jurisdictional wetlands (Appendix 2). The additional precipitation volume
predicted from the water budget should increase the hydrology and hydrologic footprint of these
rehabilitation areas. In the areas proposed for reestablishment, additional precipitation volume
predicted from the water budget should raise hydroperiods to those mimicking current jurisdictional
(rehabilitation) areas.
MMI installed a reference wetland monitoring well in a natural area matching the design wetland
approximately 1,500 feet northeast of the site on 31 March 2016 (Figure 6). The water table has
remained within 12 inches of the ground surface at this well almost continuously from Apr 1 to July 5,
aside from a six-day period in mid-June when it dropped 1 to 2 inches lower. Local rain data indicate
that many months of current year exceed historical 70th percentiles for wetness as shown in figure 7,
below.

Final Mitigation Plan -- Mogensen Mitigation Inc.
Although the average hydroperiod for these four rehabilitation gauges was measured at approximately
13.2%, the rainfall during this same timeframe was 75% greater than the average and therefore
significantly higher than normal. It can be assumed that these elongated hydroperiods shown in the
pre -restoration gauge data are consistent with elevated rainfall events given that this is a precipitation
driven system. Based on the gauge data and its relationship to precipitation for this system, along with
predicted increases in water on-site from the water budget, MMI believes a target proposed
hydroperiod of 10% is realistic for the reestablishment gauges.
The proposed restoration area is relatively flat, with a gradient slope of approximately 1.2%. Most of
the underlying soils are hydric except for some slightly drier areas along the southern portion. The
soils in this area exhibit slightly higher chroma values and less distinct redoximorphic features. The
proposed ditch plugs are designed to decrease surface runoff, increase saturation frequency and
duration throughout the site, so that even the drier areas are likely to attain wetland hydrology criteria.
6.4 Site Preparation and Construction
Riparian wetland restoration at the Site will occur through wetland re-establishment and rehabilitation
of existing wetlands, on an area approximately 500 feet upstream of a jurisdictional stream. This work
will be accomplished by placing multiple clay plugs within the main surface water drainage ditches
throughout the Site. The clay plugs will be placed to maximize the retention of surface water. Ditch
remnants will be left as natural depressions to increase surface ponding capacity and act as vernal
pools in the spring. The majority of the re-establishment area will be aerated to a depth of no greater
than six inches in order to avoid disrupting the clay layer. Areas within the dripline of large trees and
the wetland rehabilitation areas will not be aerated.
Onsite soil samples were sent to GeoTesting Express lab (test results available) and the results indicate
that onsite clays may exceed the liquid limit and plasticity index specified in the construction plans in
Appendix 1. Therefore, we will amend the onsite soils to be used for plugs with a sufficient percentage
of imported fine sand or silt to conform to the plan specifications. The percentage of fine sand or silt
per ton of soil will be determined by laboratory testing prior to construction. The fine sand or silt will
be mixed with native clay to create a consistent medium for the soil plugs prior to installation. In the
event the on-site soils are unable to meet the required specifications off-site soils will be used.
6.5 Vegetation and Planting Plan
The TRHWR Site planting plan will attempt to restore a native vegetation community similar to what
presumably occurred on the site prior to its conversion to pasture use in the 1940s. The nine -acre
project site contains about a dozen large trees, several of which appear older than 70 years and
probably pre -date the conversion to pasture. As previously mentioned, these include willow oak,
swamp white oak, silver maple (Acer saccharinum), boxelder (Acer negundo), sweetgum
Tar River Headwaters Wetland Restoration Site Page 117
Final Mitigation Plan -- Mogensen Mitigation Inc.
(Liquidambar styraciflua), black gum (Nyssa sylvatica) and loblolly pine (Pinus taeda). The target
community for the planting plan is based on the existing remnant species in the pasture, species in
adjacent forests, and published descriptions for this community type (Schafale and Weakley 1990;
LeGrand 2007). The relative uniformity of the restoration area makes it unnecessary to designate
planting zones for different species.

Note: A minimum of seven species will be planted, depending on availability.
Trees to be planted will be selected from species listed in Table 2. After aerating the compacted soil
surface (except within the drip line of large trees to be protected), trees will be planted initially at 9 to
10 -foot average spacing (400 to 500 stem per acre). Gallon -size saplings will be planted using post -
hole diggers, and smaller stock will be planted using Dibble bars or similar equipment. Native herbs
are abundant on the site and will not require seeding in most areas, except where grading will occur.
Soil has been analyzed by the Person County Extension Service and found to be low in lime and
Phosphorus. We will utilize fertilizer and lime as indicated in the soil tests. No other added soil
amendments are planned. Site preparation will involve spraying for weed control except in the existing
wetlands as they contain a diverse array of desirable native perennial and herbaceous herbs, and few
exotics. Fall spraying was used on the adjacent stream buffer project to kill fescue and other non-
native pasture grasses and resulted in dense growth of opportunistic native herbaceous plants which is
preferable to fescue.

7.0 Monitoring and Performance Standards
7.1 Monitoring Plan
In order to determine success across the site, vegetation monitoring plots will be installed and
monitored across the Site in accordance with the "Stream and Wetland Monitoring Guidelines
(February 2014)." The number and locations of the permanent monitoring quadrants will be
established within the areas enhanced by planting. At least 2% of the planted area will have 100 -meter
square vegetation plots that will be located and surveyed immediately after construction. Vegetation
monitoring plots will not be installed under existing tree canopies. Vegetation monitoring will occur in
the fall (between September and November), prior to the loss of leaves.
Each annual monitoring report must be submitted to DMS by December 1St of the year during which
the monitoring was conducted. The project success criteria of 260 stems per acre must be met at the
end of the 7th year of monitoring, or monitoring will continue until the success criteria are met.
Eleven (11) self -recording groundwater monitoring gauges have been installed to gather pre -
restoration data to assist with water budget analysis. All gauges will be removed during construction
and replaced immediately after restoration activities have been completed. Some of the gauges will be
re -installed at their existing locations, and others will be moved to new locations to achieve optimal
representation of all wetland rehabilitation and reestablishment areas throughout the project site
(Figure 8). Due to the shallow natural confining layer, gauges in some areas are less than 20 inches
deep. The restored hydrology in wetlands will need to be at least 10% of the growing season, per
discussions with the IRT.

8.2 Long Term Management Plan
The site will be transferred to the DEQ Stewardship Program (or Yd party if approved). This party shall
serve as conservation easement holder and long-term steward for the property and will conduct
periodic inspection of the site to ensure that restrictions required in the conservation easement are
upheld. Funding will be supplied by the responsible party on a yearly basis until such time an
endowment is established. The DEQ Stewardship Program is developing an endowment system within
the non -reverting, interest-bearing Conservation Lands Conservation Account. The use of funds from
the Endowment Account will be governed by North Carolina General Statue GS 113A -232(d)(3).
Interest gained by the endowment fund may be used for the purpose of stewardship, monitoring,
stewardship administration, and land transaction costs, if applicable. The Stewardship Program will
periodically install signage as needed to identify boundary markings as needed. Any livestock or
associated fencing or permanent crossings will be the responsibility of the landowner to maintain.

MITIGATION PLAN October 2016 -- Person County MMI - MOGENSEN MITIGATION INC.
Water Budget Methodology and Input Data
Development of the water budget follows equations presented in the Engineering Field Handbook
(USDA, 1997). The following equations were used to determine the inflow, outflow and water available
for storage on-site.
AS/At = Q; - Q.
Where. AS/At = change in water volume per unit time
Q; = flow rate of water entering wetland
Q, = flow rate of water exiting wetland
Q;=P+R;+B;+G;+P;+T;
Where: P = direct precipitation
R, = stormwater runoff from contributing drainage area
B; = base flow from streams entering wetland
G; = groundwater entering wetland
P; = water pumped or artificially added to the wetland
T; = tidal flow into wetland
Qa=R+T+Ro+Bo+Go+Po+To
Where: E = evaporation from surface
T = transpiration
R. = stormwater runoff from site
Bo = base flow leaving wetland
Go = groundwater leaving wetland
Po = water pumped or artificially removed from wetland
To = tidal flow out of wetland
Inflow
Precipitation
The average annual precipitation over the last 30 years was 42.36 inches, per the USDA Field Office
Climate Data as recorded in Roxboro. Over the square footage of the property and contributing
watershed, a volume of 4,443,860 ft3 of rainfall was calculated.
Stormwater Runoff
The stormwater runoff was calculated using an equation presented in the Michigan Division of
Transportation Drainage Manual.
Determine weighted curve number for watershed:
CN -weighted=( CN,*A;)/ A;
CN; NRCS curve number for sub -area i
Aj= Number of sub -areas
Determine minimum amount of precipitation that will cause runoff.
I=0.2 ((1000/CNweighted)-10
Contributing Watershed Surface Water Runoff
I= 0.2((1000/80.5)
Calculate surface runoff based on runoff triggering events: (See spreadsheet)
Tar River Headwaters Wetland Restoration Site Page 35
FINAL MITIGATION PLAN -- December 2016 MMI - MOGENSEN MITIGATION INC.
SRO= (P-0.2S)2/(P+0.8S) (inches)
S=[(1000/CN)-10] (inches)
It was assumed the surface water runoff from the contributing watershed left the project site through the
main north -south ditch.
Base Flow
Base flow is assumed to be zero.
Groundwater Flow
The groundwater flow was assumed to be constant pre- and post -restoration.
Artificially Added Water
There is no water artificially added to the project site.
Tidal Flow
The water level in the wetlands is not influenced by tidal flows.
Outflow
Evapotranspiration (E + T)
The loss of water due to evaporation and transpiration (ET) was calculated using the Thornthwaite
Method. Temperature data was obtained from the USDA Field Office Climate Data as recorded in
Roxboro.
ET = 1.6*(10*Ta / I)a
Where: ET = Evapotranspiration
Ta = mean monthly air temperature (°C)
I = heat index over 12 months
a = 0.49 + 0.0179*1- 0.0000771 *12 + 0.000000675*13
I = sum of 12 i values
i = (Ta / 5) 1.514
Where: i = monthly heat index
Ta = mean monthly air temperature (°C)
Water loss due to evapotranspiration pre -restoration is 27 inches per year (877,912 ft3/year) due to a heat
index of 63.72. The value of "a" calculates to 1.492.
Water loss due to evapotranspiration post -restoration is 41 inches per year, assuming a forested land cover
(1,324587 ft3/year). (Oishi, C. et al, 20 10)
The evapotranspiration of the contributing watershed was assumed to remain constant pre- and post -
restoration.
Stormwater Runoff
Stormwater runoff was assumed to leave only from the 8.9 acres restoration site in the post restoration
condition. The runoff from the contributing watershed remains on-site during the post restoration
condition. (See spreadsheet)
Race Flow
Tar River Headwaters Wetland Restoration Site Page 36
FINAL MITIGATION PLAN -- December 2016 MMI - MOGENSEN MITIGATION INC.
Base flow is assumed to be zero.
Groundwater Flow
The groundwater flow was assumed to be constant pre- and post -restoration.
Artificially Added Water
There is no water artificially removed from the project site.
Tidal Flow
The water level in the wetlands is not influenced by tidal flows.

This is equivalent to 1.20 feet of water across the 8.92 acres project site.
The water budget results verify the presence of increased water on-site and by assuming that base
groundwater flow pre- and post -restoration are constant, these calculations present a conservative
estimate of available water.

Maintenance Plan
Tar River Headwaters Wetland Restoration Site Page 59
FINAL MITIGATION PLAN -- December 2016 MMI - MOGENSEN MITIGATION INC.
Maintenance Plan
The site shall be monitored on a regular basis by MMI staff and a physical inspection of the site
shall be conducted a minimum of once every other month 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 items listed below. Specific component/feature maintenance will be
conducted through project close-out as follows:
Connector Ditch
Routine channel maintenance and repair activities may include minor repairs to fencing, and supplemental installations of
live stakes and other target vegetation along the channel. Areas where storm water and floodplain flows intercept the
channel may also require maintenance to prevent bank failures and head -cutting.
Wetlands
Routine site walks will be conducted to identify and document potential areas of concern, such as, but not limited to areas
of low stem density or poor plant vigor, invasive species, encroachments, and livestock access. Maintenance will follow
procedures as described below under the vegetation and site boundary components.
Vegetation
Vegetation shall be maintained to ensure the health and vigor of the targeted communities. Routine vegetation
maintenance and repair activities may include supplemental planting, pruning, mulching, and fertilizing. Exotic invasive
plant species shall be controlled by mechanical and/or chemical methods. Any vegetation control requiring herbicide
application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations.
Site Boundary
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, 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.
Ford and Culvert Crossings
Ford crossings within the site may be maintained only as allowed by Conservation Easement or existing easement, or
corridor agreements.
Beaver/Wildlife Management
If beaver dams are observed on site, MMI will remove the dams and attempt to remove the beavers from the site. If
wildlife herbivory becomes a problem for the plantings, MMI will take measures to manage wildlife on the site.

Are climatic / hydrologic conditions on the site typical for this time of year? Yes X No (If no, explain in Remarks.)
Are Vegetation X Soil or Hydrology X significantly disturbed? Are "Normal Circumstances" present? Yes No X
Are Vegetation Soil or Hydrology X naturally problematic? (If needed, explain any answers in Remarks.)
SUMMARY OF FINDINGS — Attach site map showing sampling point locations, transects, important features, etc.
Hydrophytic Vegetation Present? Yes X No
Is the Sampled Area
Hydric Soil Present? Yes X No within a Wetland? Yes X No
Wetland Hydrology Present? Yes X No
Remarks:
This headwater flat wetland was cleared, ditched, and converted to pasture in 1940s. Perched hydrology on dense
subsoil is a natural condition for this wetland type. The shallow ditches effectively drain a relatively wide area, due to
hydrology being perched. Groundwater gauge data (late March to early July, 2016) indicate that the water table
fluctuates frequently above and below 12" depth.

The TRHWR project site is currently a cattle pasture with drainage ditches, located in a former
headwater depression wetland in eastern Person County, USES HUC # 03020101-010010. The
project site comprises about 8 acres and is adjacent to a stream and buffer restoration project
(about 19 acres), both of which are on a 240 acre parcel owned by Roy and Joyce Huff. The
wetland project will include plugging the drainage ditches, installing level spreaders to
redistribute flow across the restoration areas, livestock exclusion fencing, weed treatment,
and replanting the pasture with native trees, shrubs and herbs.

RE: Tar River Headwaters Wetland Restoration Site — Section 7 ESA Clearance Request
Dear Mr. Suiter:
Mogensen Mitigation, Inc. (MMI), pursuant to Section 7 of the Endangered Species Act, is
requesting concurrence that the Tar River Headwaters Wetlands Restoration Project will not
impact any listed species or species of concern. The site is located on the Huff Family Farm at
333 Bunnie Huff Road, Oxford, NC 27565 in Person County and is on the same property that is
the subject of the Tar River Headwaters Stream Mitigation Bank. That project was cleared by a
letter dated 4-9-13 from the NC Wildlife Resources Commission through a Public Notice from the
US Army Corps of Engineers (letter attached).
The new area is on the same parcel as the stream project (see the attached mapping). The
project will entail filling in artificially created ditches and fencing out livestock.
The only federally -listed species in Person County, NC is the Dwarf wedgemussel (Alasmidonta
heterodon) which must live in perennial streams (USFWS Species Report By County Report
attached).
No direct stream impacts are proposed so no impacts to any freshwater mussel species are
expected. The site will be planted with native bottomland hardwood trees and shrubs and
monitored for at least seven years. The project is being developed under contract to the NC
Division of Mitigation Services using the "Full -Delivery" bid process. MMI has been awarded the
contract and is beginning the design and approval process.
Your prompt concurrence with this request would be greatly appreciated.
Sincerely,

Re: Tar River Headwaters Wetland Restoration Site — Person County, NC
Dear Mr. Mogensen:
This letter is to inform you that a list of all federal]y-protected endangered and threatened species
with known occurrences in North Carolina is now available on the U.S. Fish and Wildlife
Service's (Service.) web page at http://"Y,v.fws.gov/raleigh. Therefore, if you have projects that
occur within the Raleigh Field Office's area of responsibility (see attached county list), you no
longer need to contact the Raleigh Field Office for a list of federal] y -protected species.
Our web page contains a complete and frequently updated list of all endangered and threatened
species protected by the provisions of the Endangered Species Act of 1973. as amended (16
U.S.C. 1531 et seq.)(Act), and a list of federal species ofconcern I that are known to occur in
each county in North Carolina.
Section 7 of the Act requires that all federal agencies (or their designated non-federal
representative), in consultation with the Service, insure that any action federally authorized,
funded, or carried out by such agencies is not likely to jeopardize the continued existence of any
federally -listed endangered or threatened species. A biological assessment or evaluation may be
prepared to fulitii chat requilenieiit wid ii -i deLumiiiiing whc,.ier additional coinsultatroil witii tiie
Service is necessary. In addition to the federally -protected species list, information on the
species' life histories and habitats and information on completing a biological assessment or
evaluation and can be found on our web page at http://www.fws.gov/raleigh. Please check the
web site often for updated information or changes.
I The teen "federal species of concern" refers to those species which the Service believes might be in need of
concentrated conservation actions. Federal species of concern receive no legal protection and their designation does
not necessarily imply that the species will eventually lie proposed foe listing as a federally endangered or threatened
species. However, we recommend that all practicable measures be taken to avoid or inininiize adverse impacts to
federal species of concern_

If your project contains suitable habitat for any of the federally -listed species known to be
present within the county where your project occurs, the proposed action has the potential to
adversely affect those species. As such, we reconunend that surveys be conducted to determine
the species' presence or absence within the project area. The use of North Carolina Natural
Heritage program data should not be substituted for actual field surveys.
If you determine that the proposed action may affect (i.e., likely to adversely affect or not likely
to adversely affect) a federally -protected species, you should notify this office with your
determination, the results of your surveys, survey methodologies, and an analysis of the effects
of the action on listed species, including consideration of direct, indirect, and cumulative effects,
before conducting any activities that might affect the species. If you determine that the proposed
action will have no effect (i.e., no beneficial or adverse, direct or indirect effect) on federally
listed species, then you are not required to contact our office for concurrence (unless an
Environ>nental Impact Statement is prepared). However, you should maintain a complete record
of the assessment, including steps leading to your determination of effect, the qualified personnel
conducting the assessment, habitat conditions, site photographs, and any other related articles.
With regard to the above -referenced project, we offer the following remarks. Our comments are
submitted pursuant to, and in accordance with, provisions of the Endangered Species Act.
Based on the information provided and other information available, it appears that the proposed
action is not likely to adversely affect any federally -listed endangered or threatened species, their
formally designated critical habitat, or species currently proposed for listing under the Act at
these sites. We believe that the requirements of section 7(a)(2) of the Act have been satisfied for
your project. Please remember that obligations under section 7 consultation must be
reconsidered if`. (1) new information reveals impacts of this identified action that may affect
listed species or critical habitat in a manner not previously considered; (2) this action is
subsequently modified in a manner that was not considered in this review; or, (3) a new species
is listed or critical habitat determined that may be affected by the identified action.
However, the Service is concerned about the potential impacts the proposed action might have
on aquatic species. Aquatic resources are highly susceptible to sedimentation. Therefore, we
recommend that all practicable measures be taken to avoid adverse impacts to aquatic species,
including implementing directional boring methods and stringent sediment and erosion control
measures. An erosion and sedimentation control plar> should be submitted to and approved by
the North Carolina Division of Land Resources, Land Quality Section prior to construction.
Erosion and sedimentation controls should be installed and maintained between the construction
site and any nearby down -gradient surface waters. In addition, we recommend maintaining
natural, vegetated buffers on all streams and creeks adjacent to the project site.
The North Carolina Wildlife Resources Commission has developed a Guidance Memorandum (a
copy can be found on our website at (http://www.fws.gov/raleigh) to address and mitigate
secondary and cumulative impacts to aquatic and terrestrial wildlife resources and water quality.
We recommend that you consider this document in the development of your projects and in
completing an initiation package for consultation (if necessary).

Dear Mr. Pottern
Thank you for your letter dated May 18, 2016, Subject: Request for Comments —
for the Tar River Headwaters Wetland Mitigation Site located at 333 Bunnie
Huff Rd, Roxboro NC. The following guidance is provided for your
information.
Projects are subject to the Farmland Protection Policy Act (FPPA) requirements
if they may irreversibly convert farmland (directly or indirectly) to non-
agricultural use and are completed by a federal agency or with assistance from a
federal agency. Farmland means prime or unique farmlands as defined in section
1540(c)(1) of the FPPA or farmland that is determined by the appropriate state or
unit of local government agency or agencies with concurrence of the Secretary of
Agriculture to be farmland of statewide local importance.
For the purpose of FPPA, farmland includes prime farmland, unique farmland,
and land of statewide or local importance. Farmland subject to FPPA
requirements does not have to be currently used for cropland. It can be
forestland, pastureland, cropland, or other land, but not water or urban built-up
land.
Farmland does not include land already in or committed to urban development
or water storage. Farmland already in urban development or water storage
includes all such land with a density of 30 structures per 40 -acre area. Farmland
already in urban development also includes lands identified as urbanized area
(UA) on the Census Bureau Map, or as urban area mapped with a tint overprint
on the United States Geological Survey (USGS) topographical maps, or as
urban -built-up on the United States Department of Agriculture (USDA)
Important Farmland Maps.
The area in question meets one or more of the above criteria for Farmland.
Farmland area will be affected or converted. Enclosed is the Farmland
Conversion Impact Rating form AD 1006 with PARTS II, IV and V completed by
NRCS. The corresponding agency will need to complete the evaluation,
according to the Code of Federal Regulation 7CFR 658, Farmland Protection
Policy Act.
The Natural Resources Conservation Service
is an agency of the Department of Agriculture's
Natural Resources mission.

STEPS IN THE PROCESSING THE FARMLAND AND CONVERSION IMPACT RATING FORM
Step 1 - Federal agencies (or Federally funded projects) involved in proposed projects that may convert farmland, as defined in the Farmland Protection Policy Act (FPPA)
to nonagricultural uses, will initially complete Parts I and III of the form. For Corridor type projects, the Federal agency shall use form NRCS-CPA-106 in place
of form AD -1006. The Land Evaluation and Site Assessment (LESA) process may also be accessed by visiting the FPPA website, http://fppa.nres.usda.gov/lesa/.
Step 2 -Originator (Federal Agency) will send one original copy of the form together with appropriate scaled maps indicating location(s)of project site(s), to the Natural
Resources Conservation Service (NRCS) local Field Office or USDA Service Center and retain a copy for their files. (NRCS has offices in most counties in the
U.S. The USDA Office Information Locator maybe found at http://offices.usda. op v/scripts/nd[SAPI.dll/oip public/USA map, or the offices can usually be
found in the Phone Book under U.S. Government, Department of Agriculture. A list of field offices is available from the NRCS State Conservationist and State
Office in each State.)
Step 3 - NRCS will, within 10 working days after receipt of the completed form, make a determination as to whether the site(s) of the proposed project contains prime,
unique, statewide or local important farmland. (When a site visit or land evaluation system design is needed, NRCS will respond within 30 working days.
Step 4 - For sites where farmland covered by the FPPA will be converted by the proposed project, NRCS will complete Parts II, IV and V of the form.
Step 5 - NRCS will return the original copy of the form to the Federal agency involved in the project, and retain a file copy for NRCS records.
Step 6 - The Federal agency involved in the proposed project will complete Parts VI and VII of the form and return the form with the final selected site to the servicing
NRCS office.
Step 7 - The Federal agency providing financial or technical assistance to the proposed project will make a determination as to whether the proposed conversion is consistent
with the FPPA.
INSTRUCTIONS FOR COMPLETING THE FARMLAND CONVERSION IMPACT RATING FORM
(For Federal Agency)
Part I: When completing the "County and State" questions, list all the local governments that are responsible for local land
use controls where site(s) are to be evaluated.
Part III: When completing item B (Total Acres To Be Converted Indirectly), include the following:
1. Acres not being directly converted but that would no longer be capable of being farmed after the conversion, because the
conversion would restrict access to them or other major change in the ability to use the land for agriculture.
2. Acres planned to receive services from an infrastructure project as indicated in the project justification (e.g. highways,
utilities planned build out capacity) that will cause a direct conversion.
Part VI: Do not complete Part VI using the standard format if a State or Local site assessment is used. With local and NRCS
assistance, use the local Land Evaluation and Site Assessment (LESA).
1. Assign the maximum points for each site assessment criterion as shown in § 658.5(b) of CFR. In cases of corridor -type
project such as transportation, power line and flood control, criteria #5 and #6 will not apply and will, be weighted zero,
however, criterion #8 will be weighed a maximum of 25 points and criterion #11 a maximum of 25 points.
2. Federal agencies may assign relative weights among the 12 site assessment criteria other than those shown on the
FPPA rule after submitting individual agency FPPA policy for review and comment to NRCS. In all cases where other
weights are assigned, relative adjustments must be made to maintain the maximum total points at 160. For project sites
where the total points equal or exceed 160, consider alternative actions, as appropriate, that could reduce adverse
impacts (e.g. Alternative Sites, Modifications or Mitigation).
Part VII: In computing the "Total Site Assessment Points" where a State or local site assessment is used and the total
maximum number of points is other than 160, convert the site assessment points to a base of 160.
Example: if the Site Assessment maximum is 200 points, and the alternative Site "A" is rated 180 points:
Total points assigned Site A 180 X 160 = 144 points for Site A
Maximum points possible = 200
For assistance in completing this form or FPPA process, contact the local NRCS Field Office or USDA Service Center.
NRCS employees, consult the FPPA Manual and/or policy for additional instructions to complete the AD -1006 form.

INTRODUCTION
At the request of Mogensen Mitigation Inc. (MMI), Ecological Engineering performed a soils
evaluation on the Tar River Headwater Wetland Site shown on the attached hydric soil delineation
figure. The site is immediately upstream of the Tar River Headwaters Bank, located off of Bunnie
Huff Rd. near Oxford, NC. The site is located in LRR P, MLRA 136, located in the uplands of the
Southern Piedmont.
The site evaluation was for the purpose of determining if hydric soils are in the proposed wetland
restoration project areas offered, in response to RFP #16-006476 from the NC Department of
Environment and Natural Resources, Division of Mitigation Services.
SITE DESCRIPTION
Tar River Headwater Wetland is a fairly flat open pasture with a gentle slope towards a
jurisdictional stream, UT to Tar River. There are a few trees scattered throughout with one main
ditch and two lateral ditches. The site has been heavily grazed by livestock over the past 50
years: as evidenced by the compacted layers within the soil profile.
METHODS
A two-inch Dutch auger was used to hand bore 17 holes. An auger and shovel were used to dig
five (5) soil pits for detailed soil description, labeled SB 1-5(See attached descriptions, photos and
Figure 1). The 22 locations were used to determine extent of hydric soils shown on Figure 1. This
determination for the presence of hydric soil indicators is described in the manual Field Indicators
of Hydric Soils in the United States, 2010, USDA Natural Resources Conservation Service.
Hydric indicator utilized on this site:
F3: Depleted Matrix: 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. 5 cm (2 inches) if the 5 cm is entirely within the upper 15 cm (6 inches) of the soil, or
b. 15 cm (6 inches), starting within 25 cm (10 inches) of the soil surface
Notes: A depleted matrix requires a value of 4 or more and chroma of 2 or less. Redox
concentrations, including soft iron -manganese masses and/or pore linings, are required in soils
with matrix colors of 4/1, 4/2, or 5/2.
The soils were evaluated under moist conditions.
RESULTS
Borings were performed at 17 locations and pits were dug at 5 locations as shown on the
attached figure; see the five (5) soil pit sheets.
1. The hydric indicator F3 was met in nine of the 17 auger borings starting within the top six
(6) inches.
2. Two of the auger borings started the layer meeting the indicator at 10 inches.

EE Project # 30815-003 2
Tar River Headwaters Wetland Restoration Site Page 99
FINAL MITIGATION PLAN -- December 2016 MMI - MOGENSEN MITIGATION INC.
3. The remaining six auger borings didn't show hydric soils within the upper 16 inches.
4. All five (5) of the shovel dug soil pits started the layer meeting the F3 indicator within six
(6) inches of the surface.
5. Most of the borings have a dark brown loam A horizon averaging 2 inches deep; then a
silty clay loam/clay B horizon with brown colors and distinct/prominent redox features. The
B horizon extended throughout the holes to boring termination. The clay is sticky and
plastic.
6. These borings are different than the mapped soil of Orange. These soils are closer to a
Wehadkee soil mapping unit.
CONCLUSION
It is my professional opinion the Tar River Headwater Wetland Site exhibits evidence of hydric
indicators in the upper 16 inches, consistent with Wehadkee soils, throughout most of the area
evaluated. Wehadkee soils are considered hydric by the USDA Natural Resources Conservation
Service.
Disclaimer: Design plans and strategies for this project area have yet to be determined.
Ecological Engineering, LLP has not evaluated the design approach, design hydroperiod, or other
methodologies necessary to determine the likelihood of meeting regulatory success criteria.

MEMORANDUM FOR RECORD
December 5, 2016
SUBJECT: Tar River Headwater Wetland Restoration Site - NCIRT Comments during 30 -day
Mitigation Plan Review
PURPOSE: The comments listed below were posted to the NCDMS Mitigation Plan Review
Portal during the 30 -day comment period in accordance with Section 332.8(8) of the 2008
Mitigation Rule.
NCDMS Project Name: Tar River Headwaters Wetland Restoration Site, Person County, NC
USACE AID#: SAW -2016-01101
NCDMS #: 97071
30 -Day Comment Deadline: December 2, 2016
Mac Haupt, NCD WR, November 22, 2016:
1. Section 6.1 and 6.2 -(Conceptual Approach and Wetland Design) - DWR agrees in
principle with the conceptual approach outlined in the draft Mitigation Plan. Given the
jurisdictional call by the Raleigh office of the Corps of Engineers, DWR agrees with the
amount of wetland re-establishment and rehabilitation proposed. The site has 3 relatively
shallow ditches that drain surface water from the site. The hydrology and soil
characteristics on site are driven by episaturation rather than endosaturation found in
most high clayey soils in the Piedmont and upper Coastal Plain of NC.
The Mitigation Plan states the soils on the site are more Wedhakee like than the mapped
Iredell. DWR believes that will these soils do show hydric soil indicators and likely will
continue or develop more indicators; however, DWR believes the series is more like a
wetter version of the Iredell given the heavy, dense clays found on site.
DWR recommends that gauge placement be representative of the site, from an elevation
standpoint and that there are a couple of gauges in the rehabilitation areas.
2. Section 6.3-Hydroperiod Justification- DWR concurs with the target hydroperiod of 10%
for the re-establishment gauges.
3. Section 7.2 -Performance Standards- DWR concurs with the Performance Standards listed
in Table 4.
Andrea Hughes, USACE, December 2, 2016
1. Page 21, Table 3: Please confirm the acreage amounts in the table. Section 1.0 states the
site is approximately 9.98 acres. Table 3 indicates the site, including uplands, is 8.92
acres. Page 7 indicates the 1.12 acre non -hydric area in the southeast corner of the
project site does not exhibit redoximorphic features and questions whether this area was
hydric in the past. Table 3 indicates the upland area (in the southeast corner) is 1.27
acres and page 4 indicates the upland area is approximately 1.4 acres. According to table
3, the wetland rehabilitation areas in the center and southwest corner total 1.12 acres.
2. Page 21, Section 7.1: Please provide a map of proposed monitoring locations for
vegetation plots.
3. Page 21, Section 7.1: The plan states that groundwater gauges (11) will be removed
during construction and replaced after restoration activities are completed. The table on
page 22 states 8 gauges will be monitored post construction. Since 3 gauges are outside
the mitigation site boundaries, we assume that 8 gauges will be replaced and monitored.
Please correct this section for consistency.

5. Page 22, Table 4: Vegetation performance standards are 320 stems/acre at year 3, 260
stems/acre at year 5, and 210 stems/acre at Year 7. Please remove the reference to no bare
or low-density areas greater than 0.25 acre.
6. Page 22, Section 8.2: The long term management plan must identify the long term
manager for the site. Also, the plan states that funding will be supplied by the
responsible party until such time an endowment is established? Please provide additional
details including identification of the "responsible party", the amount of funding that will
be provided, the party receiving the funding, and the timing of the proposed transfer of
funds.
7. Other: The mitigation plan does not address financial assurances. The plan must provide
a statement as to the party responsible for default and the mechanism to address the
deficiency.

Re: Tar River Headwaters Wetland Restoration Site, Person County, NC - Response to FINAL
Comments on Draft Mitigation Plan (25 Oct 2016).
USACE AID#: SAW -2016-01101, Person County
NCDMS #: 97071
Dear Ms. Hughes:
Thank you for the most recent final comments. We have revised the Wetland Mitigation Plan per
all comments. The following letter explains how we have addressed each comment.
Comments from: Mac Haunt, NCD WR, November 22,2016:
1. Section 6.1 and 6.2- (Conceptual Approach and Wetland Design) - DWR agrees in principle with the
conceptual approach outlined in the draft Mitigation Plan. Given the jurisdictional call by the Raleigh
office of the Corps of Engineers, DWR agrees with the amount of wetland re-establishment and
rehabilitation proposed. The site has 3 relatively shallow ditches that drain surface water from the site.
The hydrology and soil characteristics on site are driven by episaturation rather than endosaturation found
in most high clayey soils in the Piedmont and upper Coastal Plain of NC.
The Mitigation Plan states the soils on the site are more Wedhakee like than the mapped Iredell. DWR
believes that will these soils do show hydric soil indicators and likely will continue or develop more
indicators; however, DWR believes the series is more like a wetter version of the Iredell given the heavy,
dense clays found on site. DWR recommends that gauge placement be representative of the site, from an
elevation standpoint and that there are a couple of gauges in the rehabilitation areas.
MMI Response: The 11 existing groundwater gauges in the project area will be reinstalled after
construction to achieve optimal representation of all wetland rehabilitation and re-establishment areas
and landscape features across the project site. See the new Figure 8 for approximate groundwater
gauge and vegetation plot locations.
2. Section 6.3-Hydroperiod Justification- DWR concurs with the target hydroperiod of 10% for the re-
establishment gauges. (No response required)
3. Section 7.2 -Performance Standards- DWR concurs with the Performance Standards listed in Table 4.
(No response required)
Comments from: Andrea Huzhes, USACE, December 2, 2016
Page 21, Table 3: Please confirm the acreage amounts in the table. Section 1.0 states the
site is approximately 9.98 acres. Table 3 indicates the site, including uplands, is 8.92 acres.
Page 7 indicates the 1.12 acre non -hydric area in the southeast corner of the project site does not
exhibit redoximorphic features and questions whether this area was hydric in the past. Table 3
indicates the upland area (in the southeast corner) is 1.27 acres and page 4 indicates the upland
area is approximately 1.4 acres. According to table 3, the wetland rehabilitation areas in the
center and southwest corner total 1.12 acres. MMI Response: The component acreages
throughout the plan text and tables have been revised for consistency. The as -built plan will
record acreages to the nearest thousandth.
2. Page 21, Section 7.1: Please provide a map of proposed monitoring locations for
vegetation plots. MMI Response: We have added Figure 8 after the Performance
Standards which shows the approximate (proposed) vegetation plot locations and the
approximate groundwater gauge locations.
3. Page 21, Section 7.1: The plan states that groundwater gauges (11) will be removed during
construction and replaced after restoration activities are completed. The table on page 22 states 8 gauges
will be monitored post construction. Since 3 gauges are outside the mitigation site boundaries, we
assume that 8 gauges will be replaced and monitored. Please correct this section for consistency. MMI
Response: The eleven (11) existing gauges will be removed during construction and all will be
reinstalled in the approximate locations shown on the new Figure 8.
4. Page 22, Table 4: How were the growing season dates determined? MMI Response: Language
has been added below Table 4 explaining the growing season duration rationale.
5. Page 22, Table 4: Vegetation performance standards are 320 stems/acre at year 3, 260 stems/acre at
year 5, and 210 stems/acre at Year 7. Please remove the reference to no bare or low-density areas greater
than 0.25 acre. MMI Response: The Table 4 Performance Standards have been updated using the
stem density requirements indicated, and the last sentence was removed.
6. Page 22, Section 8.2: The long term management plan must identify the long term manager
for the site. Also, the plan states that funding will be supplied by the responsible party until
such time an endowment is established? Please provide additional details including
identification of the "responsible party", the amount of funding that will be provided, the party
receiving the funding, and the timing of the proposed transfer of funds. MMI Response: The
verbiage is template language developed by the Corps and DMS for Full -Delivery mitigation
projects and has not been revised.
2
7. Other: The mitigation plan does not address financial assurances. The plan must provide a
statement as to the party responsible for default and the mechanism to address the deficiency.
Response: This mitigation site is a full -delivery project with the State of North Carolina (NC
DMS contract DEQ #6746). Performance bonding financial assurance is provided to the State
of North Carolina as a contractual requirement.
I hope these responses clearly explain the revisions and changes we have made to the Final
Mitigation Plan.
