1 Project Summary
1.1 Project Location and Description
The Hollowell Mitigation Project (Project) is located approximately seven miles southwest of Goldsboro
in Wayne County, NC (35.35814, -78.11642). The Project is located within the Neuse River Basin 8-digit
HUC 03020201, in the NC Department of Environmental Quality (NCDEQ) sub-basin 03-04-02 (Warm
Water Thermal Regime). This sub-basin spans portions of Johnston and Wayne Counties and includes the
municipalities of Goldsboro, Selma, Pine Level, Mount Olive and Princeton. The Project furthers the 2010
Neuse River Basin Priority Plan (RBRP) goals by promoting nutrient and sediment reduction in agricultural
areas by restoring and preserving wetlands, streams, and riparian buffers, as well as focusing mitigation
projects for North Carolina Department of Transportation (NCDOT) in areas where they provide the most
functional improvement to the ecosystem. Also, the ecologically valuable Neuse River floodplain is
protected in perpetuity within the Project area.
The Project includes the restoration, enhancement, preservation, and permanent protection of eight
stream reaches totaling approximately 8,979 linear feet of streams; and the preservation, re-
establishment, and enhancement of riparian wetlands totaling 10.52 acres. The Project also results in
nutrient offset credits, riparian buffer restoration, and buffer preservation through the Division of Water
Resources. The Project will provide significant ecological improvements and functional uplift through
stream and aquatic habitat restoration, and through decreasing nutrient and sediment loads within the
watershed. The mitigation plan provides a detailed project summary and Table 1 provides a summary of
project assets. Figures 1a and 1b illustrate the project mitigation components.
1.2 Monitoring Schedule and Reporting
The Project will be monitored on a regular basis with physical inspections to occur a minimum of twice
per year throughout the seven-year post-construction monitoring period, or until performance standards
are met. The measure of stream restoration success will be documented by bankfull flows and no change
in stream channel classification. Sand bed channels are dynamic and minor adjustments to dimension and
profile are expected. Wetland restoration success will be documented by hydrology. The measure of
vegetative success for the Project will be the survival of at least 210 seven-year old planted trees per acre
with an average height of 10 feet at the end of year seven of the monitoring period. Site inspections and
monitoring reports will also identify components and features that require routine maintenance or
adaptive management. The easement holder and long-term steward is Unique Places to Save (UP2S).
UP2S will be responsible for annual inspection of the Project after close-out to ensure that restrictions in
place required by the recorded Conservation Easement document are being upheld.
1.3 Project Goals and Objectives
The Project will meet the goals and objectives described in the Hollowell Final Approved Mitigation Plan
and will address general restoration goals and opportunities outlined in the NC DMS Neuse River Basin
RBRP (DEQ 2010). More specifically, watershed goals and management strategies will be met by:
• Reducing sediment, soil erosion, turbidity, and nutrient inputs such as nitrogen and phosphorus
to the Neuse River Watershed.
• Restoring, enhancing, preserving and protecting headwater streams, wetlands, riparian buffers
and aquatic habitat functions.

2

• Improving riparian corridor management and targeting restoration of impacted streams and
riparian buffer areas.
• Promoting agronomic farm management techniques and implementing agricultural BMPs and
water quality features such as nutrient management and wetlands restoration.
To accomplish these project-specific goals, the following objectives will be measured to document overall
project success:
• Provide a floodplain connection to the incised Project stream reaches by lowering bank height
ratios (BHRs) to less than 1.2, thereby promoting a more natural headwater flow regime and
overbank flood flows,
• Improve bedform diversity by increasing scour pool spacing and depth variability,
• Increase native species riparian buffer and wetland vegetation density/composition along
streambank and floodplain areas that meet requirements of a minimum 50-foot-wide and 210
stems/acre after the monitoring period,
• Improve aquatic habitat and fish species diversity and migration through the addition of in-stream
cover and native woody debris,
Site protection is provided by a 72-acre conservation easement with a minimum width of 50 feet from the
top of the restored stream banks. The easement protects all project streams, wetlands and aquatic
resources in perpetuity.
1.4 Project Success Criteria
The success criteria for the Project will follow approved performance standards and monitoring protocols
from the final approved mitigation plan; which was developed in compliance with the USACE October
2016 Guidance, USACE Stream Mitigation Guidelines (April 2003 and October 2005), and 2008
Compensatory Mitigation Final Rule. Cross-section and vegetation plot data will be collected in Years 0, 1,
2, 3, 5, and 7. Stream and wetland hydrology data and visual monitoring will be reported annually. Specific
success criteria components and evaluation methods are described below.
1.4.1 Single-Thread Streams
Stream Hydrology: Four separate bankfull or over bank events must be documented within the seven-year
monitoring period and the stream hydrology monitoring will continue until four bankfull events have been
documented in separate years. Stream hydrology monitoring will be accomplished with pressure
transducers installed in pools and correlating sensor depth to top of bank elevation. Recorded water depth
above the top of bank elevation will document a bankfull event. The devices will record water depth hourly
and will be inspected quarterly. In addition to the pressure transducers, traditional cork gauges will be
installed at bankfull elevation and will be used to document bankfull events with photographs.
Stream Profiles, Vertical Stability, and Floodplain Access: Stream profiles, as a measure of vertical stability
and floodplain access will be evaluated by looking at Bank Height Ratios (BHR). In addition, observed
bedforms should be consistent with those observed for channels of the design stream type(s). The BHR
shall not exceed 1.2 along the restored Project stream reaches. This standard only applies to restored
reaches of the channel where BHRs were corrected through design and construction. Vertical stability will
be evaluated with visual assessment, cross sections and, if directed by the IRT, longitudinal profile.

3

Stream Horizontal Stability: Cross-sections will be used to evaluate horizontal stream stability on restored
streams. There should be little change expected in as-built restoration cross-sections. If measurable
changes do occur, they will be evaluated to determine if the changes represent a movement toward a more
unstable condition (e.g., downcutting, erosion) or a movement towards increased stability (e.g., settling,
vegetation establishment, deposition along the streambanks, decrease in width/depth ratio). Cross-
sections shall be classified using the Rosgen Stream Classification method and all monitored cross-sections
should fall within the quantitative parameters defined for channels of the design stream type.
Reference photo transects will be taken at each permanent cross-section. Lateral photos should not
indicate excessive erosion or continuing degradation of the streambanks. Photographs will be taken of both
streambanks at each cross-section. A survey tape stretched between the permanent cross-section
monuments/pins will be centered in each of the streambank photographs. The water elevation will be
shown in the lower edge of the frame, and as much of the streambank as possible will be included in each
photo. Photographers will attempt to consistently maintain the same area in each photo over time.
Streambed Material Condition and Stability: After construction, there should be minimal change in the
particle size distribution of the streambed materials, over time, given the current watershed conditions
and future upstream sediment supply regime. Because the streambed material and sediment supply is
predominantly sand with minimal gravel, significant changes in particle size distribution and channel
substrate are not expected.
Jurisdictional Stream Flow: Monitoring of stream flow will be conducted to demonstrate that the restored
stream systems classified as intermittent exhibit surface flow for a minimum of 30 consecutive days
throughout some portion of the year during a year with normal or below normal rainfall conditions. Stream
flow monitoring will be accomplished with pressure transducers installed in pools and correlating sensor
depth to the downstream top of riffle elevation. If the pool water depth is at or above the top of riffle
elevation, then the channel will be assumed to have surface flow. The devices will record water elevation
twice per day and will be inspected quarterly to document surface hydrology and provide a basis for
evaluating flow response to rainfall events.
1.4.2 Headwater Streams
Seasonal Flow: Surface flow must be documented using automatic pressure transducers (flow gauges).
Continuous surface water flow within the valley or crenulation must be documented to occur every year
for at least 30 consecutive days during the prescribed monitoring period. This will be accomplished in the
same approach as Jurisdictional Stream Flow above.
Channel Formation: During monitoring years 1 through 4, the preponderance of evidence must
demonstrate a concentration of flow indicative of channel formation within the topographic low-point of
the valley or crenulation as documented by the following indicators:
• Scour (indicating sediment transport by flowing water)
• Sediment deposition (accumulations of sediment and/or formation of ripples)
• Sediment sorting (sediment sorting indicated by grain-size distribution with the primary path of
flow)
• Multiple observed flow events (must be documented by gauge data and/or photographs)
• Destruction of terrestrial vegetation
• Presence of litter and debris

4

• Wracking (deposits of drift material indicating surface water flow)
• Vegetation matted down, bent, or absent (herbaceous or otherwise)
• Leaf litter disturbed or washed away
During monitoring years 5 through 7, the stream must successfully meet the requirements above and the
preponderance of evidence must demonstrate the development of stream bed and banks as documented
by the following indicators:
• Bed and banks (may include the formation of stream bed and banks, development of channel
pattern such as meander bends and/or braiding at natural topographic breaks, woody debris, or
plant root systems)
• Natural line impressed on the bank (visible high-water mark)
• Shelving (shelving of sediment depositions indicating transport)
• Water staining (staining of rooted vegetation)
• Change in plant community (transition to species adapted for flow or inundation for a long
duration, including hydrophytes)
• Changes in character of soil (texture and/or chroma changes when compared to the soils abutting
the primary path of flow)
1.4.3 Wetlands
Wetland Hydrology: The performance standard for wetland hydrology will be a minimum 12 to 16 percent
based on the suggested wetland saturation thresholds for soils taxonomic subgroups provided by the IRT
and on-site wetland reference data. The proposed success criteria for wetland hydrology will be when the
soils are saturated within 12 inches of the soil surface for 12 to 16 percent (27 to 36 days) of the growing
season (March 21 through November 6) based on WETS data table for Wayne County, NC. The saturated
conditions should occur during a period when antecedent precipitation has been normal or drier than
normal for a minimum frequency of 5 years in 10 (USACE, 2005 and 2010b). Precipitation data will be
obtained from the Cherry Research Station near Goldsboro (GOLD), which is approximately 4 miles east
from the Project site and a rain gauge was installed on site.
1.4.4 Vegetation
Vegetation monitoring will occur in the fall each required monitoring year, prior to leaf drop. Plots will be
monitored in years 1, 2, 3, 5, and 7. Vegetative success for the Project during the intermediate monitoring
years will be based the survival of at least 320, three-year-old planted trees per acre at the end of Year 3
of the monitoring period; and at least 260, five-year-old, planted trees per acre that must average seven
feet in height at the end of Year 5 of the monitoring period. The final vegetative restoration success criteria
will be achieving a density of no less than 210, seven-year-old planted stems per acre that must average
10 feet in height in Year 7 of monitoring.
1.4.5 Visual Assessment
WLS will conduct visual assessments in support of mitigation performance monitoring. Visual assessments
of all stream reaches will be conducted twice per monitoring year with at least five months in between
each site visit for each of the seven years of monitoring. Photographs will be used to visually document
system performance and any areas of concern related to streambank and bed stability, condition of in-
stream structures, channel migration, active headcuts, live stake mortality, invasive plant species or animal
browsing, easement boundary encroachments, and general streambed conditions.

2.2 Design Approach
2.2.1 Stream
The Project stream design approach includes a combination of Stream Restoration, Enhancement, and
Preservation activities. Priority Level I Restoration reaches incorporate the design of a single-thread
meandering channel and headwater stream valley, with parameters based on data taken from reference
site comparisons, published empirical relationships, NC Coastal Plain Regional Curves, and hydrologic and
hydraulic analyses. The restoration of a stable planform and dimension, frequent overbank flows and a

6

restored riparian buffer will provide the appropriate hydrology and sediment transport throughout the
project catchments. All non-vegetated areas within the easement were planted with native vegetation
and any areas of invasive species were removed and/ or treated.
• Reach UT1-R1 – Reach UT1-R1 begins at the Project limits flowing northwest to reach UT1-R2
totaling 2,131 linear feet of Priority Level I and Headwater restoration. The restoration of UT1-R1
ends near field edge as the valley turns northeast towards the Neuse River. At this location, the
channel gradually transitions into single-thread channel and the ditch that flows offsite was
plugged to the property line.

• Reach UT1-R2 – Reach UT1-R2 begins downstream of UT1-R1 and flows northeast to the limits of
the Project. UT1-R2 totals 2,007 linear feet of Priority Level I restoration. Restoration included
excavating a new single-thread channel and plugging adjacent ditches to improve hydrological
function and hyporheic zone interaction.

• Reach UT2-R1 (upper) – UT2-R1 is a perennial stream that begins at a spring head within a mature
forested area. The existing headwater stream and wetland system is higher functioning with a
mature riparian buffer due to minimal historic impacts. UT2-R1 (upper) totals 228 linear feet of
Preservation.

• Reach UT2-R1 (lower) – UT2-R1 (lower) was graded to the natural valley topography from its
existing channelized condition. UT2-R1 (lower) is a mix of Priority Level I and Headwater
restoration of 615 linear feet. The valley bottom was graded to restore the natural
microtopographic variability that is common within headwater systems. The system will be
allowed to maintain a small pilot channel or multi-thread channels and diffuse flow paths.

• Reach UT2-R2 – The restoration of UT2-R2 ties into UT2-R3 as the valley turns to the north
towards the Neuse River. Restoration of UT2-R2 included 1,151 linear feet of Priority Level I and
II single-thread channel restoration.

• Reach UT2-R3 – UT2-R3 includes 1,923 linear feet of Enhancement Level II along the downstream
wooded section. A riparian buffer was planted along the left bank greater than 50 feet wide and
an abandoned culverted crossing was removed to restore a more natural flow path. In-stream
grade control structures were strategically placed along the lower portion to help protect the
existing mussel communities and maintain overbank flooding.

• Reach UT2A – UT2A is graded to the natural valley topography from its existing channelized
condition. UT2A is a mix of Priority I and headwater restoration totaling 615 linear feet. UT2A
starts at the Project limits and flows northeast to the confluence with UT2-R1 (lower).

• Reach UT2B – UT2B is a perennial stream flowing from a man-made pond upstream of the Project
to the confluence of UT2-R2 and UT2-R3. UT2B comprises 257 linear feet of Preservation due to
the stable condition and a mature riparian buffer.

2.2.2 Wetland
• Riparian Wetland Restoration (W2a, W3a, and W4a) - Wetland areas W2a, W3a, and W4a
contain soil conditions favorable for both rehabilitating and re-establishing wetlands. As a direct
result of implementing a Priority Level I restoration, ditch plugging, limited soil manipulation (less
than one-foot depth), and revegetation, the wetland hydrology will be restored and allow the
areas to regain their aquatic functions. An overbank flooding regime will be restored throughout
these areas by raising the stream bed elevation to reconnect the floodplain. WLS compared
monitoring data from successful stream and wetland restoration projects in similar headwater
valleys within the same or similar soil types over the past decade, and expects these areas will
experience seasonal wetness for prolonged periods and conditions are favorable to support
appropriate wetland hydrology.

• Riparian Wetland Enhancement (W3 and W4) - As described above, restoration activities include
ditch plugging, minimal grading and blending of microtopography, to provide significant
functional uplift across the project area. This approach will also improve and enhance the
hyporheic zone interaction and hydrology to existing wetland areas W3 and W4. Wetland
enhancement areas were planted with native wet tolerant species. The restoration of the stream
channels will improve areas of adjacent wetlands through higher water table conditions (elevated
stream profile) and a more frequent over-bank flooding regime.

• Riparian Wetland Preservation (W1 and W2) - W2 is an existing riparian wetland system that
begins at a spring head within a mature forested area and W1 is a jurisdictional wetland in a
mature forested area adjacent to Reach UT2-R3. The existing stream and wetland complex is
forested, stable, and undisturbed. These existing headwater stream and wetland systems are
higher functioning with mature riparian buffer due to minimal historic impacts. The wetland
preservation area is protected in perpetuity through a permanent conservation easement. This
approach extends the wildlife corridor throughout the entire riparian valley, while providing a
hydrologic connection and critical habitat linkage within the catchment area.
3 As-Built (Baseline) Condition
3.1 As-built Survey
An as-built survey conducted under the responsible charge of a North Carolina Professional Land Surveyor
(Marshall Wight, PLS with WithersRavenel), was utilized to document the baseline condition of the Project
post-construction. The Project construction and planting were completed in April 2020 and as-built survey
was completed in May and June 2020. Baseline monitoring activities occurred in April and May 2020. The
as-built survey included a topographic surface survey, locating the constructed stream channels, in-stream
structures, monitoring device locations, a longitudinal profile survey for each project reach, and cross-
section surveys for each reach.
3.2 As-Built Plans/ Record Drawings
The results of the as-built survey establish and document post-construction or baseline conditions and
will be used for comparing annual post-construction monitoring data. The as-built plans or record
drawings were developed utilizing the final construction plans as the “background”, and then overlaying
the as-built survey information on the plan and profile sheets. Any significant adjustments or deviations

8

made to the final construction plans during construction are shown as redline mark-ups or callouts on the
as-built survey plan sheets. The as-built plans/record drawings are located in Appendix E.
3.3 As-Built/ Baseline Assessment
No deviations of significance were documented between the final construction plans and the as-built
condition that may affect channel performance or changes in vegetation species planted. A small area of
concern was documented along the left floodplain UT2-R2 at approximate station 27+75. This area is
receiving concentrated flow from the adjacent field and minor erosion was observed along the terrace
side slopes. Temporary coir wattles were installed as a proactive stabilization measure to prevent further
erosion and until the permeant groundcover and buffer vegetation becomes established in this area. In
addition, a ford stream crossing was installed along UT1-R1 at approximate station 24+00 to provide
future property access for the landowner and power company. The crossing is located outside the
conservation easement and no mitigation credits were calculated in any areas outside of the easement
boundaries. No major issues or mitigating factors were observed immediately after construction which
require consideration or remedial action.
3.3.1 Morphological Assessment
Morphological data for the as-built profile was collected between April and May 2020. Refer to
Appendices B and D for summary data tables, morphological plots, and stream photographs.

3.3.1.1 Stream Longitudinal Profile
The MY0 stream longitudinal profiles closely match the design parameters. Measurements were taken at
the beginning or head of each feature (e.g., riffle, pool) and at the maximum pool depth. The constructed
riffles are depicted as straight lines with consistent slope breaks. Various locations along the longitudinal
profiles illustrate multiple slope breaks due to the installation of log structures and woody debris within
the streambed. The constructed riffle slopes and pool depths vary slightly from design parameters due to
field adjustments and fine sediment migration during construction. Minor piping was noted at two of the
in-stream structures but is expected to resolve naturally as minor adjustments occur in the streambed at
these locations. The MY0 stream longitudinal profiles illustrate that the bedform diversity and features
installed are consistent with intended design approach.
3.3.1.2 Stream Horizontal Pattern
The MY0 plan form geometry or pattern measurements fell within acceptable ranges of the design
parameters for all restored reaches. The parameters such as sinuosity, radius of curvature, and meander
width ratio were documented on constructed single-thread channels. Any lateral channel adjustments in
stream pattern do not present a stability concern or indicate a need for remedial action and will be
assessed visually during the annual monitoring reports. The results of the planimetric survey show that
the restored horizontal geometry is consistent with intended design approach.
3.3.1.3 Stream Horizontal Dimension
The MY0 channel dimensions generally match the design parameters and are within an acceptable stable
range of tolerance. It is expected that over time that some pools may accumulate fine sediment and
organic matter, however, this is not an indicator of channel instability. Maximum riffle depths are
expected to fluctuate slightly throughout the monitoring period as the channels adjust to restored flow
regime.

3.3.2 Stream Hydrology
3.3.2.1 Stream Flow
Two pressure transducers (flow gauges) were installed in April 2020 in the headwater restoration sections
in reach UT1-R1 and UT2-R1 to document baseflow conditions. The flow gauge locations are within the
upper one-third of the project reaches as shown on Figures 1a and 1b and data will be included in the
Monitoring Year 1 Report.
3.3.2.2 Bankfull Events
Two crest gauges were installed in April 2020 to document bankfull events. WLS installed a conventional
cork crest gauge, along with pressure transducers to validate flood status. One gauge was installed on
UT1-R2 and the other on UT2-R2. Stream hydrology data will be included in the Monitoring Year 1 Report
in this section and in the appendices. Recorder locations can be found on Figures 1a and 1b.
3.3.3 Headwater Stream Channel Formation
During monitoring years 1 through 4, the preponderance of evidence must demonstrate a concentration
of flow indicative of channel formation within the topographic low-point of the valley or crenulation as
documented by the following indicators. This evidence will be addressed in the Monitoring Year 1 Report.
3.3.4 Wetland Hydrology
Eight groundwater wells were installed in April 2020, including two reference wells, to monitor wetland
hydrology. One well, located in the floodplain of UT1-R2, is outside of a wetland and will be used to
monitor groundwater hydrology, not wetland hydrology. Groundwater well locations can be found on
Figures 1a and 1b and the data will be included in subsequent monitoring reports.
3.3.5 Vegetation
Monitoring of the 24 USACE permanent vegetation plots was completed during April and May of 2020.
Vegetation data can be found in Appendix C with the associated photos located in Appendix B. The MY0
average planted density is 717 stems per acre, which exceeds the interim measure of vegetative success
of at least 320 planted stems per acre at the end of the third monitoring year. Volunteer species were not
noted at baseline monitoring but are expected to establish in upcoming years. A significant population of
privet (Ligustrum sinense) was located along the headwater restoration portion of UT1-R1 prior to
construction. Construction activities removed the existing privet within the easement, but this area will
be closely monitored, and re-sprouts will be treated as needed to prevent further establishment. Visual
assessment of vegetation throughout the planted area indicates herbaceous vegetation is establishing.
4 Methods
Stream cross-section monitoring was conducted using a Topcon RL-H5 Laser Level. Morphological data
were collected at 11 cross-sections. Survey data were imported into Microsoft Excel® for data processing
and analysis. The stage recorders include an automatic pressure transducer set in PVC piping in the
channel. The elevation of the bed and top of bank at each stage recorder location was recorded to be able
to document presence of water in the channel and out of bank events. Visual observations (i.e. wrack or
debris lines) and traditional cork crest gauges will also be used to document out of bank events.
Vegetation success is being monitored at a total of 24 permanent vegetation plots for the USACE (46
permanent vegetation plots in total: 16 Joint 404/401 plots, 8 additional USACE/404 plots, and 22
additional DWR/401 vegetation plots). Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol

10

for Recording Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species composition and
density of planted species. Data are processed using the CVS data entry tool. In the field, the four corners
of each plot were permanently marked with PVC at the origin and rebar at all corners. Photos of each plot
are to be taken from the origin each monitoring year. Tree species and height will be recorded for each
planted stem and the transects will be mapped and new locations will be monitored in subsequent years.
Wetland hydrology is monitored to document success in wetland restoration and enhancement areas
where hydrology was affected. This is accomplished with eight automatic pressure transducer gauges
(located in groundwater wells) that record daily (twice per day) groundwater levels. Pressure transducers
are HOBO Water Level (13ft) Data Loggers made by Onset. Seven have been installed within the wetland
crediting area. Of the seven in the credited areas, two are installed within reference wetland areas. One
additional gauge was installed on UT1-R2 to document groundwater changes post-restoration in
comparison to pre-restoration data. One automatic pressure transducer is installed above ground for use
as a barometric reference. Gauges are downloaded quarterly and wetland hydroperiods are calculated
during the growing season. Gauge installation followed current regulatory guidance. Visual observations
of primary and secondary wetland hydrology indicators are also recorded during quarterly site visits.
