1 PROJECT SUMMARY
1.1 PROJECT LOCATION AND DESCRIPTION
The Swift Creek Mitigation Plan (SCMP) is an approved permittee-responsible mitigation bank. The SCMP project
area is approximately 196.5 acres, located eleven miles northeast of the City of Rocky Mount in Edgecombe
County, NC (35.999286°, -77.605591°). The SCMP is located within the 8-digit HUC 03020101, in the NC
Department of Environmental Quality (NCDEQ) sub-basin 0302010108 (Swift Creek), within the Tar-Pamlico
River Basin.
The SCMP includes the restoration, enhancement, and permanent protection of five stream reaches totaling
8,890 linear feet of stream as built and the establishment of approximately 200-ft wide Tar-Pamlico riparian
buffers totaling 14.86 acres, with 27.31 acres being permanently preserved. The SCMP also includes the re-
establishment, enhancement, and preservation of 53.8 acres of riparian wetlands. The SCMP 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 Appendix A, Table 1, provides a summary of project assets. Appendix A, Figure 1 illustrates
the project mitigation components (Appendix B).
Monitoring Year 1 (MY1) activities occurred from September to October 2022. This report presents the data for
MY1. The SCMP meets the MY1 success criteria for stream hydrology, stream pattern, profile, and dimension,
and wetland hydrology. Based on these results, the SCMP is on trajectory to meet interim and final success
criteria in these areas. Vegetation monitoring results indicate that multiple plots are not currently meeting
performance standards. A supplementary planting is planned for the winter of 2023 to address this deficiency
and bring vegetative trajectories back into compliance with performance standards. For more information on
the chronology of the project history and activity, refer to Appendix A, Table 2. Relevant project contact
information is presented in the appendices in Appendix A, Table 2 and project background information is
presented in Appendix A, Table 3.
1.2 PROJECT GOALS AND OBJECTIVES
The SCMP will meet the goals and objectives described in the Swift Creek Final Approved Permittee Responsible
Mitigation Plan (May 2019) and will address general restoration goals and opportunities outlined in the North
Carolina Division of Mitigation Services (NC DMS) Tar-Pamlico River Basin River Basin Restoration Priorities
(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
Tar-Pamlico River Watershed.
• Restoring, enhancing, preserving, and protecting headwater streams, wetlands, riparian buffers, and
aquatic habitat functions.
• Improving riparian corridor management and targeting restoration of impacted streams and riparian
buffer areas.
To accomplish these plan-specific goals, the following objectives will be measured to document overall project
success:
Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180
WSP December 2022 Page 5
• Promote wetland hydrology by raising channelized stream beds and filling drainage ditches;
• Plant wetland areas with native tree species to restore the natural vegetative communities;
• Reconstruct stream channels to have the appropriate slope, planform, and cross-sectional geometry
for the region of the Coastal Plain in which the SCMP is located;
• Size reconstructed stream channels to inundate adjacent floodplains and wetlands frequently;
• Stabilize stream banks using bioengineering, natural channel design techniques, and grading to reduce
bank angles and bank height;
• Install in-stream structures and woody debris to promote aeration of water, create habitat, and
influence the creation of bed forms commonly found in sand bed channels;
• Restore riparian buffer areas with native tree species to stabilize channels, filter flood flows and runoff,
and supplement wetland plantings; and
• Remove a large acreage of land from agricultural production within the Mitigation Plan to further
improving water quality.
1.3 MONITORING SCHEDULE AND REPORTING
The SCMP will be monitored on a regular basis with physical inspections to occur a minimum of once annually
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 SCMP
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. Palustrine Group is the
easement holder and long-term steward noted in the PRMP; however, Palustrine Group has since been acquired
by Water and Land Solutions (WLS). WLS will be responsible for annual inspection of the SCMP after close-out
of the monitoring period to ensure that restrictions in place required by the recorded Conservation Easement
document are being upheld.
1.4 PROJECT SUCCESS CRITERIA
The success criteria for the SCMP 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 the 2008 Compensatory Mitigation
Final Rule. Cross-section and vegetation plot data will be collected during monitoring years 0, 1, 2, 3, 5, and 7.
Stream and wetland hydrology data and visual monitoring will be collected annually. Specific success criteria
components and evaluation methods are described below.
1.4.1 SINGLE-THREAD STREAMS
Stream Hydrology: Four separate bankfull flow events, occurring in separate years, must be documented on the
restoration and enhancement reaches during monitoring years 1 through 7. Stream monitoring will continue
until success criteria in the form of four bankfull events in separate years have been documented.
Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180
WSP December 2022 Page 6
Stream Profiles, Vertical Stability, and Floodplain Access: A longitudinal profile was collected as part of the as-
built survey; however, longitudinal profile surveys will not be conducted during the seven-year monitoring
period unless other indicators during the annual monitoring indicate a trend toward vertical and lateral
instability. Migration of pools and bed forms is expected and does not require remedial action. Stream pattern
and profile will be assessed visually as described below.
Stream profiles, as a measure of vertical stability and floodplain access will be evaluated by looking at bank
height ratio (BHR). Shallow section cross-sections on the restoration reaches should be stable and should show
little change in bankfull area, maximum depth ratio and width-to-depth ratio. Shallow cross-sections should fall
within the parameters defined for channels of the appropriate Rosgen stream type (when applicable). The BHR
will not exceed 1.2 and the entrenchment ratio (ER) will be no less than 2.2 at any measured riffle cross-section.
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 and cross sections.
Stream Horizontal Stability: Stream horizontal stability will be measured by cross-sections. Two permanently
monumented cross-sections have been installed per 1,000 linear feet of stream restoration work and represent
approximately 50% shallow/riffle and 50% pool areas within each restoration and enhancement reach. Each
cross-section has been permanently marked with pins to establish its location. Cross-section surveys will be
performed during monitoring years 0, 1, 2, 3, 5, and 7 and will include points measured at all breaks in slope,
including top of bank, bankfull, edge of water, and thalweg. It is important to note that in sand bed channels,
pools and bed forms (ripples, dunes, etc.) may migrate over time as a natural function of the channel hydraulics.
These sorts of bed changes do not constitute a trend towards instability or indicate a need for remedial actions.
The BHR and ER at any measured riffle cross-section should not change by more than 10% from the baseline (as-
built) condition during any given monitoring interval (e.g., no more than 10% between years 1 and 2, 2 and 3, 3
and 5, or 5 and 7). For example, if BHR is calculated to be 0.8 at a given cross section following monitoring year
1, acceptable BHR calculated for that cross section in monitoring year 2 would be 0.8 ± 0.08 (0.72 to 0.88). If any
changes do occur, these changes will be evaluated to assess whether the stream channel is showing signs of
instability. Indicators of instability include a vertically incising thalweg or eroding channel banks. Changes in the
channel that indicate a movement toward stability or enhanced habitat include a decrease in the width-to-depth
ratio in meandering channels or an increase in pool depth. Remedial action would not be taken if channel
changes indicate a movement toward stability.
Permanent photograph stations at each cross-section will document stability and channel evolution during the
monitoring period. Photographs will be taken looking across channel, looking upstream, and looking
downstream, showing as much of the banks and channel as possible. The survey tape will be centered in each
photograph and the water line will be located near the lower edge. An effort will be made to consistently show
the same photograph area in each subsequent monitoring event.
Streambed Material Condition and Stability: Pebble count procedures will not be conducted for this project
due to the sand bed nature of the streams.
1.4.2 MACROINVERTEBRATES
Habitat availability and macroinvertebrate communities will be monitored in streams where functional uplift is
attributed to maintenance or improvements in biological communities. Macroinvertebrate sampling will be
Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180
WSP December 2022 Page 7
conducted once a year during monitoring years 3, 5, and 7. Monitoring stations will be located on every perennial
restoration and enhancement reach greater than 1,000 feet in length. Additional sampling points will be
established per additional 2,000 feet of length on each restoration or enhancement reach (1,000’ = 1 point,
3,000’ = 2 points, 5,000’ = 3 points, etc.). Sampling locations will be based on riffle condition and best
professional judgment and occur within the same riffle year-to-year.
Macroinvertebrate sampling will be processed by a qualified taxonomist and/or NCDWR certified laboratory for
macroinvertebrates. Macroinvertebrates will be identified to genus. Biotic indices, including percent EPT
(Ephemeroptera, Plecoptera and Trichoptera), North Carolina Biotic Index, Shannon-Weaver Diversity Index,
Taxa Richness and a species list for each station, will be listed in the monitoring report. Each report will include
a summary of the current results and all past monitoring events in tabular format.
1.4.3 HEADWATER STREAMS
Seasonal Flow: Under normal circumstances, surface water flow within the valley or crenulation will be
documented to occur every year for at least 30 consecutive days during the seven-year monitoring period.
Additional monitoring may be required if surface water flow cannot be documented due to abnormally dry
conditions.
Channel Formation: During monitoring years 1 through 4, a 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 within primary flow path)
• Multiple observed flow events (must be documented by gauge data and/or photographs)
• Destruction of terrestrial vegetation
• Presence of litter and debris
• 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
in addition 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)
Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180
WSP December 2022 Page 8
• Changes in character of soil (texture and/or chroma changes when compared to the soils abutting the
primary path of flow)
1.4.4 WETLANDS
Wetland Hydrology: Hydroperiod ranges are based on the suggested wetland saturation thresholds for soils
taxonomic groups. The predominant soils within the wetland restoration and enhancement areas consist of
Roanoke soils. Therefore, the performance standard is that well data from the wetland enhancement areas
indicate that groundwater is within 12 inches of the soil surface for 7% target saturation period for monitoring
years 1 and 2 and 10-12% for monitoring years 3 – 7 of the annual growing season during normal weather
conditions. The growing season for the SCMP season was taken from the National Weather Service (NWS)
Cooperative Observer Program (COOP) Station 318500, which is located in Tarboro, Edgecombe County. Based
on this growing season, success will be achieved at the SCMP if the water table is within 12 inches of the soils
surface for 17 consecutive days or more during the established growing season (March 21 to November 11) for
monitoring years 1 and 2 and a minimum of 23 consecutive days for monitoring years 3 – 7.
Automated groundwater recording wells will be installed in accordance with the techniques and standards
described in the USACE’s “Technical Standard for Water-Table Monitoring of Potential Wetland Sites” (ERDC TN-
WRAP-05-2, June 2005). An automated rain gauge has been installed to collect and record rainfall at the SCMP.
The rain gauge incorporates a tipping-bucket design (at a 0.01-inch tipping interval) and records sufficient data
to determine rainfall quantities, rates and duration. Rainfall data collected from the gauge will be correlated
with local weather stations and compared to the National Resource Conservation Service (NRCS) Climate
Analysis for Wetlands Tables (WETS tables) to determine if normal rainfall conditions exist during the monitoring
period. The rain gauge will be downloaded during each site visit. If necessary, rainfall from the nearest weather
station may be used to supplement data collected on-site if issues occur with the sampling equipment.
1.4.5 VEGETATION
Vegetation monitoring will occur in monitoring years 0, 1, 2, 3, 5, and 7 between August 1 and leaf drop.
Vegetative success for the SCMP during the intermediate monitoring years will be based the survival of a
minimum of 320 stems per acre at year three; a minimum of 260 stems per acre at year five; and a minimum of
210 stems per acre at year seven. Planted trees in each plot must measure 7 feet in height at year five and 10
feet in height at year seven. 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.
1.4.6 TAR-PAMLICO RIPARIAN BUFFERS
Approximately 26.10 acres of Tar-Pamlico riparian buffers (TOB – 200 feet) were restored within the SCMP
project area. A Construction and Planting Completion Report was submitted to the NC Department of
Environmental Quality (NCDEQ) in accordance with the Division of Water Resources (DWR) Section 401 and
Buffer permitting. Vegetation monitoring will occur in monitoring years 0, 1, 2, 3, 5, and 7 between August 1
and leaf drop. Within the riparian buffer restoration areas, a minimum of 320 stems per acre must be present
at year three and a minimum of 260 stems per acre must be present at year seven. Planted trees in each plot
must measure an average of 7 feet in height at year five and 10 feet in height at year seven. Volunteer species
may count towards the stems per acre requirements, but species must be included on the approved planting
palette. Any single species will only account for up to 50% of the required number of stems within any vegetation
plot and shall include a minimum of four native hardwood species or four native hardwood tree and native shrub
Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180
WSP December 2022 Page 9
species. Where the vegetation plot is dominated by volunteer species, remedial action as specified in the
Adaptive Management Plan may be required. The extent of invasive species coverage will also be monitored
and controlled as necessary throughout the required monitoring period.
1.4.7 VISUAL ASSESSMENT
Visual assessments of all stream reaches will be conducted annually. 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, excess sediment, active headcuts, live stake mortality, invasive plant
species or animal browsing, easement boundary encroachments, and general streambed conditions.

3 METHODS
Stream cross-section monitoring was conducted using a Topcon AT-B4 Automatic Level. Three-dimensional
coordinates associated with cross-section data were collected in the field (NAD83 State Plane feet PIPS 3200).
Morphological data were collected at 12 cross-sections. Following field activities, survey data was imported into
Microsoft Excel® and the NCDMS cross-section ShinyApp tool for processing and analysis. The crest gauges and
groundwater monitoring wells include an automatic pressure transducer set in PVC piping. Visual observations
(i.e. wrack or debris lines) will also be used to document out of bank events.
Vegetation success is being monitored at a total of twenty-five permanent vegetation plots—thirteen within
riparian buffer areas and twelve within wetland enhancement areas. Vegetation plot monitoring follows the
Carolina Vegetation Survey (CVS) Level 1 (Planted Stem Inventory Plots) and Level 2 (Total Wood Stem Inventory
Plots) survey protocols and includes analysis of species composition and density of planted species. In the field,
the four comers of each plot were permanently marked with a large T-post at the origin and small T-posts at the
other corners. Photos of each plot are taken from the origin corner facing across the plot each monitoring year.
Tree species and height are recorded for each planted stem.

4 MONITORING YEAR 1 ASSESSMENT
AND RESULTS
The dates of MY1 monitoring activities are detailed in Appendix A, Table 2. All MY1 monitoring data is presented
in this report and in the appendices. The Project is on track to meet stream and wetland hydrology interim
success criteria; adaptative management has been proposed for the vegetation across the SCMP to bring it into
compliance with performance standards. All monitoring device locations are depicted on the Current Condition
Plan View (CCPV) (Appendix B, Figure 1).
4.1 STREAM MORPHOLOGICAL ASSESSMENT
4.1.1 HEADWATER STREAM CHANNEL FORMATION
To assess the formation of headwater streams, visual assessments and NCDEQ Stream Assessment forms were
completed for SA and SB headwater stream reaches. SB headwater exhibited multiple indicators of headwater
stream formation including scour, sediment deposition, and matted vegetation. SA has not yet demonstrated
many aspects of headwater stream channel formation; however, these are anticipated to develop over the
course of the monitoring period. NCDEQ Stream Assessment forms for each headwater restoration reach can
be found in Appendix D.
4.1.2 STREAM HORIZONTAL PATTERN & LONGITUDINAL PROFILE
Visual assessment was utilized for assessment of MY1 horizontal and vertical stability. The visual assessment for
each stream reach documented that during MY1, stream channel pattern, longitudinal profiles, and in-stream
structure location/function still closely match the profile design parameters and MY0/baseline conditions
(Appendix D). Minor channel adjustments in riffle slopes, pool depths and pattern were observed based on
natural sediment migration and stream bank vegetation establishment but do not present a stability concern.
4.1.3 STREAM HORIZONTAL DIMENSION
The MY1 channel dimensions generally match the design parameters and are within a stable range of tolerance.
Twelve cross-sections were installed on restoration reaches, with six located in riffles and six located in pools.
Of the five riffle cross sections in stream A and one in stream K, all had BHR < 1.2 and Entrenchment Ratios >
2.2, meeting performance standards. Some exhibited a > 10 % deviation from As-Built conditions; however,
these changes in all cases moved them closer to the desired target values for ER. All twelve permanently installed
cross-sections show little to no change in bankfull area when compared to as-built measurements. It is expected
that over time 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 the post-restoration flow regime. Cross-section overlays and measurements can be
found in Appendix D and summarized in the tables below.

4.2 STREAM HYDROLOGY
Stream hydrology restoration was monitored via five crest gauges installed along restoration reaches. Stream
hydrology performance criteria is the documentation of four separate bankfull flow events in separate
monitoring years. Eight bankfull events were recorded along reach SK (CG2) following rainfall events: four in
July, two in August, one in September, and one in October of 2022. A total of seven bankfull events were
recorded along SA: one at SA1 - CG 4 and six at SA2 - CG 5 Because SA2 (CG5) is located within the lower portion
of Wetland 12, it responded frequently to rainfall events with a water level AGS. Bankfull events were
determined by crest gauge water levels recorded above ground surface. Overall, stream restoration reaches are
on track to reach performance standard targets during the monitoring period. A summary of bankfull events is
located in in Table 4.2.1 below.
4.2.1.1 MY1 BANKFULL EVENTS SUMMARY TABLE
4.3 MACROINVERTEBRATES
Habitat availability and macroinvertebrate communities is monitored in streams where functional uplift is
attributed to maintenance or improvements in biological communities. Macroinvertebrates were sampled prior
to beginning restoration activities, and sampling will be conducted once a year during monitoring years 3, 5, and
7 to assure no decrease in diversity and abundance has occurred by MY7. No macroinvertebrate sampling
occurred in MY1.
4.4 WETLAND HYDROLOGY
Hydrology data was collected from six shallow groundwater monitoring wells within wetland enhancement
areas to assess wetland hydrologic performance standards. During MY1, enhancement areas on average were
saturated within 12-inches of the soil surface for 46 days (19% of the growing season), meeting the MY1
performance standard of 17 days (7% of the growing season). Monitoring Well 2 did not meet performance
Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180
WSP December 2022 Page 16
standards individually; however, three months in the growing season resulted in rainfall under the 30% climate
normal for the area. Hydrographs for each well and monthly rainfall data can be found in Appendix E.

4.5 VEGETATION
Monitoring of the twenty-five permanent vegetation plots was completed during September 2022. Vegetation
data can be found in Appendix C with the vegetation plot photos located in Appendix B. The MY1 average planted
density is 311 stems per acre, which does not meet the interim measure of vegetative success of at least 320
planted stems per acre at the end of the third monitoring year. Volunteer species noted at MY1 included winged
elm (Ulmus alata), persimmon (Diospyros virginiana), and sycamore (Platanus occidentalis). Visual assessment
of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is well established
throughout the project.
A supplementary planting is planned for the winter of 2023 to address this performance standard. The proposed
supplementary planting will include planting of both bare root seedlings and additional live staking along the
restoration reaches.

5 CONCLUSION
The first year of monitoring for the Swift Creek PRMP has been completed. Monitoring results indicate that the
project is on track to meet stream dimension, profile, pattern, and hydrology performance standards and
wetland hydrology performance standards by Monitoring Year 7. Macroinvertebrate sampling was not
scheduled to occur during MY1, per the mitigation plan. Vegetation monitoring results reveal that multiple plots
are not currently meeting stem density standards. A supplementary planting is planned for the winter of 2023
to address this performance standard and bring vegetation densities back into compliance with performance
standards.
