PART 5 - TECHNICAL APPROACH
5.1 PROJECT COALS AND OBJECTIVES
Norman's Pasture Restoration Site is a headwater stream and wetland system in Sampson County that has
been substantially modified to maximize grazing and agriculture. The site consists of a collection of
tributaries that drain down moderately- sloped valleys onto the floodplain of Stewarts Creek, a large
fourth -order blackwater stream. The streams have been moved and straightened and the wetlands have
been ditched in order to clear and drain the land for anthropogenic uses. Despite these modifications,
there are areas with high - quality wetlands that remain on the property. The site offers the potential to
reconnect a continuous headwater stream and wetland headwater corridor with Stewarts Creek. The
restored headwater system would provide a buffer to surrounding grazing and agricultural operations. The
site also offers the potential to restore and protect a range of unique aquatic resources in one setting —
existing riparian wetlands, a steep forested tributary, lower gradient seep -fed headwaters, and artesian
springs.
In the Cape Fear River Basin Restoration Priorities (NCEEP 2009), the goals for the 8 -digit hydrologic
unit include focusing on water quality improvements and protecting Outstanding Resource Waters. The
project goals will support these larger aims and include:
- Reconnect a continuous stream and wetland headwater system to Stewarts Creek
- Improve and expand riparian habitat along Stewarts Creek
- Buffer nutrient inputs from adjacent agricultural and grazing practices
The following objectives will be implemented to achieve these goals:
- Redevelop headwater stream- wetland complexes that have previously been impacted by ditching
- Protect and integrate existing riparian wetlands into the project design . y _____

- Fence all easement arias to protect the site's resources from grazing
5.2 PROJECT DESCRIPTION
i'
The Norman's Pasture Restoration Site (NPRS) is headwater system located approxim tel R+t1AL1TY
west of Magnolia, North Carolina in Sampson County. The project begins southwest of t e r r
Cornwallis Road and MJ Johnson Road and Stewarts Creek, a fourth -order stream, forms the southern
boundary. The location of the project is shown in Figure 1.
Watershed Description
The site is within the 03030006 (Cape Fear 06) Watershed Cataloging Unit (8 -digit HUC) and the Local
Watershed Unit 03030006110040 (14 -digit HUC). The project's 14 -digit HUC has been identified by the
North Carolina Ecosystem Enhancement Program (EEP) as a targeted local watershed. Figure 2 shows the
site in relation to the project watershed that is comprised of 179 acres before reaching Stewarts Creek.
Below the project site, Stewarts Creek continues for approximately four river miles before it flows into
Six Runs Creek. Neither Stewarts Creek nor Six Rums Creek are listed on the 2010 303(d) list. The
project site is also not within a water supply watershed. Stewarts Creek (DWQ Index 18- 68 -2 -10) is
classified as a Class C water with the supplemental classification of swamp waters (Sw).

the project site. The 1938 aerial shows that the two major ditches that run east to west were already in
place, and that a third ditch that runs north to south along the western edge of the property was likely
already constructed as well. A farm pond to the northwest of the project property was already in
existence. However, not as much land in the lower portion of the site was cleared in 1938. The lower
portion of the site north of Stewarts Creek has vegetation in 1938, but this is soon cleared for either
agriculture or grazing by the 1966 aerial. The later aerials show a similar pattern in land use. The site
shows a significant amount of ponding in several of the historic photographs.
In addition to the historical aerials, KCI also reviewed the available historic topographic maps.
Topographic maps from 1962 and 1984 were found (see Figure 4). KCI inquired at the local NRCS office
for any older topographic or drainage maps, but no other maps were available. The 1962 topographic map
indicates that the site hydrology generally flows north to south and then drains to the southwest corner of
Stewarts Creek. The 1984 topographic map shows this trend in greater detail, but also displays the
existing ditches and their influence on the site.
Currently, the land use in the 179 -acre project watershed is comprised mainly of forest, animal production
and agriculture. This project watershed spans the project parcels plus an additional area upstream of MJ
Johnson Road. The land use is approximately 15.8% agricultural, 45.3% forest, 34.2% pasture, 0.7%
high - density development (roads), 3.1% low- density development, (rural residences), and 0.9% water (see
Figure 3). The impervious surface within the project watershed is estimated to be 1 %. The nearest
municipalities to the site are Turkey and Magnolia. The surrounding area is rural and has low
development pressure at this time.
FEMA Floodplain Issues
The majority of the NPRS is located in the 100 -year floodplain (Zone AE) of Stewarts Creek. A flood
study is expected for this project, but it is not anticipated that the project will raise the flood elevations for
this area.
Site Constraints
There is one anticipated 20 -foot easement exception that will be included with the project to provide
landowner access to upland pasture left out of the conservation easement. The crossing will have
appropriately sized culverts installed to ensure that there are no detrimental effects on the project.
Airports
There are no airports located within five miles of the project site.
Geology and Soils
The site lies within the Rolling Coastal Plain Level IV Ecoregion within the coastal plain physiographic
province. The site is in the inner coastal plain and is underlain by the Black Creek Formation of the
Cretaceous Period. The Black Creek Formation is described as clay, gray to black, lignic and contains
thin beds and laminae of fine- grained micaceous sand and thick lenses of cross - bedded sand. Glauconitic,
fossiliferous clayey sand lenses exist in the upper part (NCDNRCD, 1985).
The Soil Survey of Sampson County describes several predominant soil series at the NPRS, including
Lumbee sandy loam, Bibb and Johnston, Johnston loam, and Chipley sand (see Appendix E for NRCS
map). Lumbee sandy loam is a nearly level, poorly drained soil is on smooth flats and in shallow
depressions on stream terraces. The Bibb and Johnston soil series is frequently flooded and has soils that
are poorly or very poorly drained and found along major streams. Johnston loam is very poorly drained
found on narrow to moderately broad floodplains. The Chipley Sand series has 0 to 2 percent slopes,
which is described as being a nearly level, moderately well- drained soil on smooth ridges. (Soil Survey of
Sampson County, USDA SCS 1985).

A soils investigation by KCI's licensed soil scientist found the soils described above in addition to Johns
fine sandy loam, Lynn Haven sand, and Torhunta fine sandy loam. A detailed map of the soils found at
the site and soil boring logs are included in Appendix C. Johns fine sandy loam is a somewhat poorly
drained to moderately well drained series found on stream terraces. Lynn Haven sand is a poorly drained
soil typical of flat areas or in large, shallow depressions. Torhunta fine sandy loam is a very poorly
drained soil found on upland bays and stream terraces.
Existing Conditions
The project streams and wetlands have all been impacted by grazing, agricultural, and other hydrologic
modifications. At this time, the northwest portion of the site is still being farmed while the remainder of
the property is open to cattle grazing. Hay is harvested from different parts of the property depending on
the year. Despite these impacts, there are still stream and wetland resources on the site that remain in
moderate to good condition. The existing site conditions are displayed in Figure 4 and Figure 5 shows the
existing site topography based on LIDAR. Site photographs illustrating the current site conditions are
included as Appendix B.
Tributary 1 (T1): This unnamed tributary to Stewarts Creek begins northwest of the project site from a
farm pond. Once it comes onto the project site, it is a stable stream within a forested riparian buffer.
However, it begins to incise shortly thereafter and flows for approximately 750 linear feet in a narrow,
steep valley. In this section, the right bank has a steep valley wall while the left bank has a higher bank
that is raw and exposed. There is a farm field just to the east of the left bank. Once T1 leaves the valley
and enters into a lower gradient farm field, the stream is channelized for approximately 550 linear feet. In
this location, T1 lacks riparian vegetation, flow diversity, and any woody debris or other habitat
structures.
T1 then is channelized to the edge of the farm field with a moderately vegetated buffer along the right
bank. There is also an artesian spring in this location where the stream makes this transition. It has been
capped with a pipe, but communication from the landowner suggests that it flowed strongly before it was
capped. The channel has been excavated in this location and the remaining spoil can be seen to the left of
the stream. Looking downstream, the right bank has moderate riparian coverage with mature trees while
the left bank is directly adjacent to the agricultural field. T1 flows through this section for approximately
200 feet before Tributary 2 enters from the left. After the confluence with the entering tributary, T1
transitions into a channel type with little evidence of ditching and with access to its floodplain. After
another 200 feet, T1 then travels along the property line as a straightened channel with spoil piles adjacent
to the left bank until T1 enters into Stewarts Creek.
Tributary 2 (T2): Tributary 2 begins in the middle of the site and flows to the north and then to the west
before joining T1 along the western edge of the site. T2 receives its primary hydrologic input from an
artesian spring that rises to the surface. Based on landowner reports, this artesian spring provides a
consistent source of hydrology. The beginning of T2 is surrounding by high quality wetlands, although
cattle have created a ponded, open water area that impedes initial flow. The wetlands have a mature
canopy with buttressed trunks. Species within the wetlands include bald cypress (Taxodium distichum),
American elm (Ulnzus americana), and river birch (Betula nigra), Currently, T2 is a functional headwater
stream at its beginning. Unlike a single- thread channel, the stream has a multiple flowpaths throughout
the wetted section that move in a linear direction. The braided system is largely shaped by the existing
trees. The flow moves toward the north, but is ponded near its source due to cattle congregating and
drinking in this area. After another 100 feet, the stream flows through a more heavily wooded area.
After flowing approximately 500 feet toward the north, T2 receives additional drainage from hillside
seepage entering from the northeast. At this point, the headwater stream flows toward the west. For the
last 680 feet of T2, the stream is a wide channelized ditch until it reaches the confluence with T1. There is

little to no movement within the channel, leaving the water essentially ponded with large amounts of
duckweed. Along the left bank of this lower section of T2, there is no riparian vegetation. The right bank
has a narrow strip of trees.
Existing Impacted Wetlands
There are many incoming seeps and riparian wetlands that have been modified to accommodate
agriculture and grazing at the NPRS as the slope transitions down to the Stewarts Creek floodplain area.
South of Tributary 2 is the largest drained wetland area at the NPRS. The land is currently used for hay or
pasture. Figure 5 shows the ditches that drain the former wetland, and Figure 6 shows the defined shallow
valley that runs through the center of the field. T2's current landscape position is to the north of the field,
but the ditched channel likely flowed through the center of this field. To the south of this field is seepage
flow that is currently confined to a forested ditch running east to west toward an outlet into Stewarts
Creek.
Along the eastern slope of the site below Cornwallis Road is a series of seeps converging toward the
Stewarts Creek floodplain. At the northeastern corner is an existing pond that holds water from an
upstream seep; this pond can be seen on Figure 5. Additional seep channels have had their outlets blocked
and are confined to ponded areas, which are open to impacts from cattle. Existing forested wetlands are
found in the lowest areas of the site, but the connections to these wetlands have been blocked or bypassed
in many areas.
Additional drained wetlands are found near Tributary 1 as it comes onto the floodplain. Ditches have been
installed to drain excess water from this area to allow for farming.
5.3 PROJECT DEVELOPMENT
A mitigation approach has been developed for NPRS that aims to balance the potential to return the
stream and wetland system to its historic condition while also integrating existing high - quality habitat
features that have developed since anthropogenic modifications have taken place. Each of the proposed
mitigation elements will be described and then a summary of the offered options will follow in the next
section. All of the streams and wetlands within the project easement will be fenced to protect them from
further grazing impacts.
Most of the project streams will be restored as headwater stream systems in existing valley slopes
previously abandoned or modified. Figure 7 shows a conceptual schematic of headwater stream
restoration.
Tributary 1, Reach 1 (TI-1) — 750 If of Stream Enhancement I
In this upper reach of T1, the stream has become incised as it cuts it way down to the valley below.
Enhancement work along this reach will focus on installing bed structures to stabilize headcuts that have
developed as the channel is cutting down to the downstream floodplain. Bank work will be targeted
primarily along the left bank where the channel has high banks. The left bank will be shaped to build a
bankfull bench and then replanted with native species. There are large, mature trees within the riparian
corridor that will be integrated into the enhancement design as much as possible to maintain the overstory
coverage.
Tributary 1, Reach 2 (T1 -2) — 1,011 If of Headwater Stream Restoration
In this section, T1 will be restored to its former headwater stream location. As TI-1 comes out of the
valley upstream, the slope changes to a low- gradient system. Instead of being constrained to the existing
ditch that the stream flows through, the restored channel will allow water to spread out and develop a

braided channel system to the west. A channel block will be removed and minor grading will be
implemented to create multiple flowpaths based on a reference stream condition. Flow will be returned to
a channel area with a minimum width of 100 feet. Woody debris will be added as needed to create flow
diversity, to add stability, and to provide habitat features.
Tributary 1, Reach 3 (T1 -3) — 275 If of Stream Enhancement II
After the confluence of T2, the existing channel of T1 transitions into a sinuous channel for
approximately 200 linear feet. This section of channel has the appropriate pattern and dimensions with
access to its floodplain. This section of channel will be connected to the restored upstream headwater
stream. The buffer will be enhanced with tree plantings and livestock excluded from the channel.
Tributary 1, Reach 4 (T1 -4) — 205 if of Stream Restoration
The existing channel of T14 is a straightened channel with remnant spoil on the banks before it runs into
Stewarts Creek. The stream will be returned to a diffuse channel pattern to the west. The existing spoil
will be excavated to allow floodplain access. Care will be taken to maintain existing trees in this location.
Tributary IA (T1A) — 187 If of Headwater Stream Restoration
The restoration of this channel will occur where an artesian well has been capped to drain an existing
headwater stream channel. The artesian well will have seep protection installed to protected the water
source and distribute the flow downstream into an existing forested, multi- thread headwater channel. This
stream will flow into the bottom of T1 -2.
Tributary 2, Reach 1 (T2 -1) — 925 If of Enhancement II (Proposed Mitigation Ratio 5:1)
This reach is already a functional headwater stream, but cattle impacts are affecting water quality and
preventing additional herbaceous vegetation from forming. The cattle are also compacting the ground at
the head of the reach, which is causing water to pond. This area will benefit greatly from having the cattle
excluded with fencing. The surrounding buffer will also be planted with native species in those areas
without established vegetation. A mitigation ratio of 5:1 is proposed for this reach due to the existing high
quality nature of the stream.
Tributary 2, Reach 2 (T2 -2) — 955 If of Headwater Stream Restoration
In this section, T2 will be relocated to the center of the field where Lidar topography shows a defined
headwater stream /wetland valley. Woody material will be added to provide habitat, stability, and flow
diversity. Existing trees along the right bank will be protected as much as possible.
Tributary 2A (T2A) — 321 if of Headwater Stream Restoration
T2A will be restored through a small headwater valley as it flows downstream to T2 within the same
proposed stream and wetland complex.
Tributary 213, Reach 1 (T213-1), 935 if of Headwater Stream Restoration
T213-1 will be restored as a headwater stream where there is currently seepage flow being stored behind a
pond. The pond will be dismantled and the seepage area will be regraded and stabilized with matting. The
channel will flow through an existing headwater valley as seen on the Lidar topography and flow down to
existing headwater stream /wetland complex that eventually joins T2. Minor grading will be completed
ensure a stable transition into this former channel.
Tributary 2B, Reach 2 (T213-2), 500 if of Stream Enhancement II (Proposed Mitigation Ratio 5:1)
This reach of T213 begins in an existing stream /wetland complex. The area has mature existing trees, but
cattle have access to this area. Upstream seepage flow has also been diverted away from the wetland.
Enhancement actions will focus on adding supplemental plantings as needed, restoring an upstream
hydrologic source, and fencing out livestock.
North Carolina Ecosystem Enhancement Program
KCI Technologies Inc /KCI Associates of North Carolina PA/KCI Environmental Technologies and Construction, Inc.
Tributary 2C (T2C), 173 If of Headwater Stream Restoration
This tributary is currently ponded at the top of the feature where seep flow enters the site. Restoration
actions will focus on redeveloping this seep into the existing valley below and tying the tributary into the
existing wetland complex that adjoins T2.
Tributary 2Ca JXa), 333 If of Headwater Stream Restoration
This tributary forms from seepage flow and quickly joins T2C. Restoration will focus on regrading a
stable headwater stream transition and replanting this section of former pasture.
Tributary 2D (T2D), 279 If of Restoration
This existing drained channel will have flow returned to it to restore a headwater stream system. Existing
fill will be removed that is blocking upstream seepage from reaching the channel. The headwater stream
valley will be regarded to the appropriate elevations to allow gradual flow through the reach.
Tributary 3, Reach 1 (T3 -1), 695 If of Enhancement I
Tributary 3 flows from seepage flow from the northeast and then transitions through an existing cypress
wetland. A multi- thread channel exists for the tributary flow, but currently the seepage flow is being
rerouted around the wetland. Enhancement actions will focus restoring flow through this section.
Tributary 3, Reach 2(T3 -2), 104 If of Headwater Stream Restoration
This reach of restoration will reconnect T3 to an outlet at Stewarts Creek that has been blocked by
excessive deposition along the larger stream. Restoration actions will focus on regrading a stable
transition from the existing T3 channel into Stewarts Creek.
Tributary 3A (T3A), 175 If of Enhancement II
This small section of Enhancement II will reconnect an active artesian spring to T' ) downstream. Minor
grading will remove blockages that are preventing flow from entering the T3 channel.
Riparian Wetland Restoration, 10.4 — 15.6 acres
Riparian wetland restoration will take place across the NPRS as described in the mitigation options in the
next section. All of the riparian wetland restoration actions will focus on reconnecting the restoration
areas to existing wetlands to expand wetland habitat and the forested corridor along Stewarts Creek. The
restoration will involve filling existing ditches as well redeveloping headwater stream systems as
described above. By restoring these headwater systems, it will elevate the local groundwater table and
slow runoff from upstream land uses such as agricultural and grazing. Besides expanding wetland habitat,
it will also increase the buffering capacity before runoff reaches Stewarts Creek.
Riparian and Wetland Vegetation
Riparian and wetland plantings will consist of native species and will be incorporated as outlined in the
restoration actions. In areas where the entire riparian buffer will be planted, a density of six hundred
eighty (680) stems per acre will be planted to achieve a mature survivability of two hundred ten (210)
trees per acre. In locations where there are existing trees and the area is to be enhanced, plants will be
installed at densities ranging between 100 and 200 stems per acre. Woody vegetation planting will be
conducted during dormancy.
Disturbed areas of T1 -I will be planted as a Mesic Mixed Hardwood Forest (Coastal Plain Subtype). This
community is typically found on moist upland soils with canopy species such as American beech (Fagits
grandifolia), tulip poplar (Liriodendron tulipifera), southern sugar maple (Acer floridanum), white oak
(Quercus alba), and northern red oak (Q. rubra). The conditions along T1 -1 are more similar to the

bluff /slope variant of this community as described by Schafale and Weakley (1990). Potential species to
be planted in this area could include:
American Hornbeam Carpinus caroliniana Swamp Chestnut Oak Q. michauxii
Tulip Poplar Liriodendron tulipifera S. Red Oak Q. falcata var. pagodaefolia
White Oak Quercus alba Common Sweetleaf Symplocos tinctoria
The remainder of the site will be planted as a Coastal Plain Small Stream Swamp (Blackwater Subtype).
Typical overstory species in this community include bald cypress ( Taxodium distichum), swamp tupelo
( Nyssa bii lora), tulip poplar (Liriodendron tulipifera), red maple (Acer rubrum), laurel oak (Quercus
laurifolia), overcup oak (Q. lyrata), swamp chestnut oak (Q. michauxii), river birch (Betula nigra), and
American elm (Ulmus americana) ( Schafale and Weakley 1990). This composition is similar to what is
already found in adjacent wetlands at the site. Potential seedlings for these areas could include:
River Birch
Betula nigra
Laurel Oak
Quercus laurifolia
Sweet Bay
Magnolia virginiana
Overcup Oak
Q. lyrata
Water Tupelo
Nyssa Mora
Swamp Chestnut Oak
Q. michauxii
Swamp Bay
Persea palustris
Bald Cypress
Taxodium distichum
On the enhanced stream banks of T1 -1, live stakes will be used in conjunction with the native herbaceous
seed mix to provide natural stabilization. Appropriate species identified for live staking may include:
Carolina Willow Salix caroliniana
Black Willow Salix nigra
Elderberry Sambucus canadensis
An herbaceous seed mix composed of appropriate native species will also be developed and used to

Monitoring will consist of the collection and analysis of data to support the evaluation of the project in
meeting established restoration objectives. Specifically, project success will be assessed utilizing
measurements of vegetation survivability and stream /wetland hydrologic monitoring. For the headwater
streams, which involves the restoration of the historic flow pattern as a multi - thread headwater stream
system to be constructed as a broad or diffuse swale with shallow flow paths, monitoring will focus
primarily on visual assessments, documentation of indicators of active flow, and hydrologic monitoring
with a series of gauges. The monitoring for the single thread stream restoration will follow more
traditional monitoring methodology as discussed below.
Duration - Monitoring will be conducted for a period of seven years following project implementation.
The first scheduled monitoring event will be conducted during the first full growing season following
project completion (Anticipated growing season of 2013).
North Carolina Ecosystem Enhancement Program
KCI Technologies Inc. /KCI Associates of North Carolina PA/KCI Environmental Technologies and Construction, Inc.
Reporting - Monitoring reports will be prepared and submitted following the completion of each growing
season. Each report will provide the new monitoring data and compare the new data against previous
findings. The monitoring report format will follow the latest EEP monitoring report template, currently
Version 1.4, published November 7, 2011.
Visual Assessment
During yearly site walks, KCI will document any areas of bank erosion, invasive species, bed aggradation
or degradation, or other problem area and evaluate whether or not corrective actions are needed.
Photograph Reference Points
Photograph reference points (PRPs) will be established to assist in characterizing the site and to allow
qualitative evaluation of the site conditions. The location of each photo point will be permanently marked
in the field and the bearing /orientation of the photograph will be documented.
Vegetation Survivability
The survivability of the vegetation plantings will be evaluated using a sufficient number of 100 -m2
vegetative sampling plots randomly placed throughout the restored wetlands and planted headwater
stream buffers to cover a minimum of 2% of the planted portion of the site. Permanent monuments will be
established at the corners of each monitoring plot and documented by either conventional survey or GPS.
The vegetation monitoring will follow the Level 2 method of the current CVS -EEP protocol
( http: / /cvs.bio.unc.edu/methods.htm). Monitoring will also comply with guidance included in
"Monitoring Requirements and Performance Standards for Stream and/or Wetland Mitigation" (NC EEP,
November 7, 2011), which states that the plots must achieve a stem density of 320 stems /acre after three
years, 260 stems /acre after five years, and 210 stems /acre after seven years to be considered successful. In
addition to density requirements, plant height will be monitored within the monitoring plots to ensure that
trees average 10 feet in height after 7 years. A photograph will be taken of each monitoring plot, allowing
yearly qualitative comparison of vegetation conditions.
Monitoring Headwater Stream Reaches
Bankfull Events, Flooding, and Active Flow Documentation
The occurrence of bankfull events and flooding functions within the monitoring period will be
documented by the use of water level gauges and photographs. A sufficient number of monitoring gauges
will be installed within the restored system to document groundwater and flooding levels.
To ensure that these systems are functioning like stream /wetland systems, regular active flow must be
documented. Two floodplain flow events must be documented within the seven -year monitoring period.
A floodplain flow event is considered to be a flow event large enough to spread flow across at least 50
percent of the floodplain width. The two floodplain events must occur in separate years; otherwise, the
monitoring will continue until two floodplain events have been documented in separate years. A network
of gauges will be deployed to document the occurrence of extended periods of shallow surface ponding,
indicative of flow. Visual signs that are indicative of flow include: visual documentation of flowing
water, presence of litter and other debris, wrack lines, sediment sorting, a pattern of disturbed leaf litter,
water staining, and changes in the plant community. During site visits to download gauges, these
indicators will be documented with photos and on field forms to be summarized in the annual monitoring
report.
Dimension
Permanent cross - sections will be established along the restored reaches. These will be surveyed during
the baseline monitoring and again during the first and second years of monitoring. The purpose of these
North Carolina Ecosystem Enhancement Program
KCI Technologies Inc. /KCI Associates of North Carolina PA/KCI Environmental Technologies and Construction, Inc.
cross - sections is not to monitor the minor changes in the dimension of the braided channel, but to
document if there is any significant change in the extent of the restored stream/wetland valley. Permanent
monuments will be established at the left and right extents of each cross - section by either conventional
survey or GPS. If the second year of monitoring shows that there is significant change, then the cross -
sections will be monitored again at years five and seven. If there is not significant change, then the cross -
section surveys will be discontinued after the second year of monitoring.
Monitoring Single Thread Stream — TI -I
Stream Stability Monitoring
The purpose of monitoring is to evaluate the stability of the restored stream. The monitoring for this part
of the restored stream will comply with guidance included in "Monitoring Requirements and
Performance Standards for Stream and/or Wetland Mitigation" (NC EEP, November 7, 2011).
Dimension
Permanent cross - sections will be established along the restored and enhanced reaches and will be used to
evaluate stream dimension stability. Permanent monuments will be established at the left and right extents
of each cross - section by either conventional survey or GPS. The cross - section surveys shall provide a
detailed measurement of the stream and banks. It shall include points on the slopes leading down to the
channel, at the top of bank, bankfull, at all breaks in slope, and the thalweg. Subsequently, width/depth
ratios, entrenchment ratios and low bank height ratios will be calculated for each cross - section.
Photographs will be taken of each cross - section during each monitoring event. Sets of bank pins in outer
meander bends will also be monitored during each of the monitoring events.
Profile
A longitudinal profile for the project reaches will be established during the baseline conditions survey.
After the initial survey, the longitudinal profile will only be surveyed if there is demonstrated bed
instability.
Stream Hydrologic Monitoring
The success of restoring the bankfull return period will be evaluated using automatic stream monitoring
gauges to record daily stream depth readings. The site must experience a minimum of two bankfull events
(in separate years) over the seven -year monitoring period.
Wetland Hydrology Monitoring
Wetland hydrology monitoring will be conducted to determine if the restored wetland areas meet the
proposed performance criteria for wetland hydrology. Monitoring will comply with guidance included in
Monitoring Requirements and Performance Standards for Stream and/or Wetland Mitigation (NC EEP,
November 7, 2011). Verification of wetland hydrology will be determined by automatic recording well
data collected within the project area. Automatic recording wells will be established within the wetland
restoration areas. Daily data will be collected from automatic wells over the 7 -year monitoring period
following implementation. These data will determine if the wetland meets the hydrology success criterion
of the water table being within 12 inches of the ground surface continuously for greater than 7.5% of the
growing season. Visual monitoring will also be conducted two times per year in each monitoring year as
per the NC EEP guidance referenced above.
