UT TO MILL SWAMP RESTORATION PROJECT, DS PROJECT NUMBER - 95019
1.0 EXECUTIVE SUMMARY
Michael Baker Engineering (Baker) restored 3,606 linear feet (LF) of perennial stream, 6.62 acres (AC) of
riparian wetlands, and enhanced 600 LF of stream along an unnamed tributary (UT) to Mill Swamp in Onslow
County, North Carolina (NC), (Appendix A). The UT to Mill Swamp Restoration Project (Site) is located in
Onslow County, approximately three miles northwest of the Town of Richlands. The Site is located in the NC
Division of Water Resources (NCDWR) sub -basin 03-05-02 and the NCDEQ Division of Mitigation Services
((DMS) formerly Ecosystem Enhancement Program) Targeted Local Watershed (TLW) 03030001-010020 of
the White Oak River Basin. The project involved the restoration and enhancement of a Coastal Plain Headwater
Small Stream Swamp system (NC WAM 2010, Schafale and Weakley 1990) from impairments within the
project area due to past agricultural conversion, cattle grazing, and draining of floodplain wetlands by ditching
activities.
The project goals directly addressed stressors identified in the White Oak River Basin Restoration Priority Plan
(RBRP) such as degraded riparian conditions, channel modification, and excess sediment and nutrient inputs.
The primary restoration goals, as outlined in the approved mitigation plan, are described below:
• Create geomorphically stable conditions along the unnamed tributaries across the Site,
• Implement agricultural Best Management Practices (BMPs) to reduce nonpoint source inputs to
receiving waters,
• Protect and improve water quality by reducing bank erosion, nutrient and sediment inputs,
• Restore stream and wetland hydrology by connecting historic flow paths and promoting natural flood
processes, and
• Restore and protect riparian buffer functions and corridor habitat in perpetuity by establishing a
permanent conservation easement.
To accomplish these goals, the following objectives were identified:
• Restore existing incised, eroding, and channelized streams by providing access to their historic
floodplain,
• Prevent cattle from accessing the riparian buffer, reducing excessive bank erosion,
• Increase aquatic habitat value by providing more bedform diversity, creating natural scour pools and
reducing sediment from accelerated bank erosion,
• Plant native species riparian buffer vegetation along stream bank and floodplain areas, protected by a
permanent conservation easement, to increase stormwater runoff filtering capacity, improve bank
stability, and shade the stream to decrease water temperature,
• Improve aquatic and terrestrial habitat through improved substrate and in -stream cover, addition of
woody debris, and reduction of water temperature, and
• Control invasive species vegetation within the project area and if necessary, continue treatments during
the monitoring period.
The project as -built condition closely mimics that proposed by the design. Differences are outlined below:
MICHAEL BAKER ENGINEERING, INC.
UT TO MILL SWAMP RESTORATION PROJECT, DMS PROJECT NUMBER - 95019
• The Stream and Wetland Mitigation Plan (Mitigation Plan) specified the planting of riparian live stakes
during construction; however, due to construction being completed during the growing season in May
2013 no live stakes were installed. During construction, it was determined that live stakes would be
installed during the dormant season. It is noted that as of March 27, 2014, approximately 300 live
stakes were installed along the stream banks in the restored single thread channel of the UTIc area.
• Permanent fencing along Reach UT3 was originally proposed 50 feet from both of the streambanks
outside of the conservation easement; however, the landowner decided to use the northern pasture for
hay production only, so fencing was installed only on the southern side of the reach to exclude cattle.
Special Notes:
In consideration of this report, the following timeline should be noted:
Completion of construction — 5/31/13
Completion of installation of tree and shrub bare roots — 6/13/13
Year 1 (2013) vegetation monitoring — 10/16/13
Live stake installation - 3/27/14
Year 1 (2013) supplemental vegetation monitoring — 5/18/14
Year 2* (2014) vegetation monitoring — 12/19/14
Year 2 (2015) vegetation monitoring — 11/13/15
Year 3 (2016) vegetation monitoring — November, 2016
Supplemental Year 1 (5/18/14) vegetation monitoring was conducted in order to provide additional
mortality data. This additional monitoring effort was done since the time that had elapsed between the
installation of the tree and shrub bare roots (6/13/13) and Year 1 vegetation monitoring (10/16/13) was
only 125 days of the growing season (March 18' through November 16th). Trees and shrubs grew for
an additional 61 days of growing season from 3/18/14 through 5/18/14 in early 2014 and were
supplementally monitored. A total of 186 days of growing season had elapsed since the trees were
planted and the supplemental Year 1 vegetation monitoring was conducted. An additional 181 days
within the growing season (5/19/14 through 11/16/14) had elapsed prior to Year 2 (2014) vegetation
monitoring, providing the required minimum of 180 days of growing season growth as stated in the
approved Mitigation Plan. As such, Baker considered the data collected on 12/19/14 to be Year 2 data
and the data collected on 11/13/15 to be Year 3 data. However, the US Army Corps of Engineers has
declined to release the credits generated from Year 2 (2014) citing too short of a period between plant
installation and monitoring. As such, the 2015 monitoring report was considered Year 2. All references
to Year 2 henceforth will indicate monitoring activities conducted during 2015. Data collected during
2014 that was previously considered monitoring Year 2 will be labeled as Year 2*.
During Year 3 monitoring, the planted acreage performance categories were functioning at 99 percent with no
bare areas and only one low stem density area to report. The average density of total planted stems, based on
data collected from the six monitoring plots following Year 3 monitoring, is 472 stems per acre. It was observed
during Year 3 vegetation monitoring that only plot 3 has not met the minimum interim success criteria of 320
trees per acre by the end of Year 3. However, all plots currently exceed the required seven-year stem density
of 210 stems per acre.
Invasive species areas of concern were observed, documented and treated accordingly during Year 3. Following
Year 3 monitoring, four areas (Areas 1, 2, 3, 4) of Chinese privet, totaling approximately 1.48 acres or 9.7
MICHAEL BAKER ENGINEERING, INC. 2
UT TO MILL SWAMP RESTORATION PROJECT, DMS PROJECT NUMBER - 95019
percent of the total planted area within UT 1 c (15.2 acres) were found to contain the invasive species. To control
areas of invasive species, these areas were treated in October and November 2016 by mechanical removal and
the use of the herbicide Glyphosate.
During Year 3 monitoring, groundwater monitoring demonstrated that five of the sixteen groundwater
monitoring wells located along Reach UT 1 c met the wetland success criteria as stated in the Site Mitigation
Plan. The gauges that met success criteria (MSAWI, MSAW4, MSAW5, MSAW8 and MSAW24)
demonstrated consecutive hydroperiods of 12 percent or greater, which ranged from 24.6 to 31.2 percent of the
growing season. The gauges that did not meet success criteria (See Table 12) demonstrated consecutive
hydroperiods of 12 percent or less which ranged from 0.6 percent to 8.7 percent of the growing season. It is
noted that MSAW7 and MSAW3 are not meeting success but are outside of the wetland restoration and hydric
soils boundary. Baker will continue to monitor the hydrology into Year 4. It should also be noted that the wells
meeting success criteria are located in the restored wetland area south of UT 1 c. The total restored wetland area
south of UT 1 c equals 3.26 acres. The wetland area north of UT 1 c is 3.36 acres. The total wetland restoration
acreage equals 6.62 acres. The total wetland acreage has been incorrectly reported in past monitoring reports
as 4.0 acres of wetland restoration. Baker and DMS are contracted at 4.0 WMUs but the project wetland acreage
is in excess of the contracted amount.
For the first three years of the project, it was observed that groundwater levels on the northern portion of UTIc
were not performing as designed for many of the wetland monitoring wells. Therefore, it was determined that
an additional six monitoring wells be installed in spring of 2016. Five wetland wells were installed in February
2016 (MSAW 19, MSAW20, MSAW21, MSAW22, MSAW23) and one in March 2016 (MSAW24). Data from
the additional five monitoring wells is located Appendix E.
During Year 2 monitoring, it was determined that monitoring wells (MSAW2, MSAW3, MSAW6, MSAW7,
MSAW9 and MSAW 10) were potentially providing erroneous data. The cause of the data errors was estimated
to be two -fold. The first cause was estimated to be a hardware issue. During field investigations, it was
determined that the water pressure sensor of some the pressure transducers had become clogged with bentonite.
The transducers have since been unclogged and elevated within the well casing to reduce the likelihood of
clogging, and the holes pumped out to remove remaining bentonite particles existing within the well casing. In
addition, all pressure transducers are cleaned during each logger download. The second cause is estimated to
be due to the installation of the wells during less than ideal conditions. Auguring well holes during in the wet
conditions of the site potentially smeared the soil of the well hole wall which could decrease soil permeability.
Due to the aforementioned issues, six additional wells were installed in February 2016 along the left floodplain
of UTlc. During subsequent well data collection, the automatic wells will be calibrated by measuring the
ground water level before the data logger is removed from the well casing. This manual measurement will
ensure accurate and real-time data provided by the well data logger.
Year 3 flow monitoring demonstrated that both flow gauges (MSFL1 and MSFL2) met the stated success
criteria of 30 days or more of consecutive flow through reaches UTla and UTlb. Both gauges demonstrated
consecutive days of flow that ranged from 59.0 days (MSFL1, UTla) to 105.0 days (MSFL2, UTlb). These
gauges demonstrated similar patterns relative to rainfall events observed in the vicinity of the Site.
The Year 3 monitoring survey data of eight (8) cross-sections indicates that the Site is geomorphically stable
and performing at 100 percent for the all parameters evaluated. The data collected are within the lateral/vertical
stability and in -stream structure performance categories.
The Site was found to have had at least two post -construction above bankfull events based on the crest gauge
readings during Year 3.

Summary information/data related to the Site and statistics related to performance of various project and
monitoring elements can be found in the tables and figures in the report Appendices. Narrative background and
supporting information formerly found in these reports can be found in the Baseline Monitoring Report and in
the Mitigation Plan available on the North Carolina Division of Mitigation Services (NCDMS) website. All
raw data supporting the tables and figures in the appendices is available from NCDMS upon request.
2.0 METHODOLOGY
The seven-year monitoring plan for the Site includes criteria to evaluate the success of the stream, wetland and
vegetation components of the project. The methodology and report template used to evaluate these components
adheres to the NCDMS monitoring guidance document dated November 7, 2011, which will continue to serve
as the template for subsequent monitoring years. The specific locations of monitoring features: vegetation
plots, permanent cross-sections, monitoring wells, flow gauges, and the crest gauge, are shown on the CCPV
sheets found in Appendix B.
The Year 3 monitoring data were collected in October, November and December 2016. All visual site
assessment data located in Appendix B were also collected in October and November 2016.
2.1 Stream Assessment — Reach UTla & UTlb
The UTla and UTlb mitigation approach involved the restoration
functions in a multi -thread headwater stream system. Monitoring
document stability and the use of water level monitoring gauges
functions.
2.1.1 Hydrology
of historic flow patterns and flooding
efforts focus on visual observations to
to document groundwater and flooding
Two automated groundwater gauges (pressure transducers) are installed along well transects, with a
total of four well transects installed in the UT 1 a and UTlb areas. The automated loggers are
programmed to collect data at 6 -hour intervals to record groundwater levels in UTla and UTlb areas.
Groundwater data collected during Year 3 monitoring are located in Appendix E.
Additionally, two flow gauges (pressure transducers) were installed to document the occurrence of
extended periods of shallow surface ponding, indicative of flow. The gauges attempt to document
flooding connectivity between the restored UTla and UTlb reaches for at least 30 consecutive days
under normal climatic conditions. Flow data collected during Year 3 monitoring are located in
Appendix E.
2.1.2 Photographic Documentation
The headwater stream reaches were photographed longitudinally beginning at the downstream portion
of the Site and moving towards the upstream end of the Site. Photographs were taken looking upstream
at delineated locations throughout the restored stream valley. The photograph points were established
close enough together to provide an overall view of the reach lengths and valley crenulations. The
angle of the photo depends on what angle provides the best view and was noted and continued in future
photos. Selected UTla and UTlb site photographs are located in Appendix B.

UT TO MILL SWAMP RESTORATION PROJECT, DMS PROJECT NUMBER - 95019
2.2 Stream Assessment — Reach UT1c
The UT 1 c mitigation approach involved the restoration of historic flow patterns and flooding functions in a
single -thread headwater stream system. Monitoring efforts focus on visual observations, the use of groundwater
level monitoring gauges, a crest gauge to document bankfull flooding events and established stream cross-
sections to monitor channel stability.
Stream survey data was collected to a minimum of Class C Vertical and Class A Horizontal Accuracy using
Leica TS06 Total Station and was georeferenced to the NAD83 State Plane Coordinate System, FIPS3200 in
US Survey Feet, which was derived from the As -built Survey. This survey system collects point data with an
accuracy of less than one tenth of a foot.
2.2.1 Morphologic Parameters and Channel Stability
Cross-sections were classified using the Rosgen Stream Classification System, and all monitored cross-
sections fall within the quantitative parameters (i.e. BHR no more than 1.2 and ER no less than 2.2)
defined for channels of the design stream type. Morphological survey data is presented in Appendix
D.
A longitudinal profile was surveyed for the entire length of channel immediately after construction to
document as -built baseline conditions for the first year of monitoring only. The survey was tied to a
permanent benchmark and measurements included thalweg, water surface, bankfull, and top of low
bank. Each of these measurements was taken at the head of each feature (e.g., riffle, pool) and at the
maximum pool depth. Yearly longitudinal profiles will not be conducted during subsequent monitoring
years unless channel instability has been documented or remedial actions/repairs are required by the
USACE or DMS.
2.2.2 Hydrology
Following as -built conditions, ten automated groundwater -monitoring stations were installed in the
UTIc wetland restoration area and follow USACE protocols (USACE 1997). Groundwater data
collected during Year 3 monitoring are located in Appendix E.
For the first three years of the project, it was observed that groundwater levels on the northern portion
of UT 1 c were not performing as designed for many of the wetland monitoring wells. Therefore, it was
determined that an additional six monitoring wells be installed in spring of 2016. Five wetland wells
were installed in February 2016 (MSAW19, MSAW20, MSAW21, MSAW22, MSAW23) and one in
March 2016 (MSAW24). Data from the supplemental six monitoring wells is located Appendix E.
Total observed rainfall at the Albert Ellis airport (KOAJ) weather station located near Richlands, NC
for the period of January through November 2016 was 54.77 inches. The WETS table for Hoffrnan
Forest station (NC4144), Onslow County was used to calculate the 30 -year average for the same period
(January through November) and is 52.84 inches. According to the Albert Ellis gauge, total rainfall
during the Year 3 monitoring period from January through October 2016 was 1.93 inches above the
historic approximated average as compared to the Hoffinan Forest station for Onslow County.
Although, total rainfall for 2016 was recorded at 1.93 inches above normal through November, it was
a relatively dry year until two significant storm events moved across the area in the fall of 2016. The
storms occurred on September 2nd and October 8' when Hurricane Matthew moved across Onslow
County. As measured by the KOAJ rain gauge at the Albert Ellis airport, total rainfall for the September
2nd event was 6.65 inches and the Hurricane Matthew event was 6.92 inches. Combined, the two fall
storms comprised 25.7% of the rain that fell in Onslow County from January to November 2016.
MICHAEL BAKER ENGINEERING, INC.
UT TO MILL SWAMP RESTORATION PROJECT, DMS PROJECT NUMBER - 95019
One crest gauge was installed on the floodplain at the bankfull elevation along the left top of bank on
UTlc approximately at Station 45+50. The highest bankfull reading recorded in Year 3 was measured
to be 2.32 feet and was estimated to have occurred on October 8, 2016. Crest gauge readings are
presented in Appendix E.
2.2.3 Photographic Documentation
Reference photograph transects were taken at each permanent cross-section. The survey tape was
centered in the photographs of the bank. The water line was located in the lower edge of the frame,
and as much of the bank as possible is included in each photograph. Photographs were also taken of
grade control structures along the restored stream, and limited to log weirs or logjams. Selected UTlc
site photographs from Year 3 monitoring are shown in Appendix B.
2.2.4 Visual Stream Morphological Stability Assessment
The visual stream morphological stability assessment involves the qualitative evaluation of lateral and
vertical channel stability, and the integrity and overall performance of in -stream structures throughout
the Project reach as a whole. Habitat parameters, and pool depth maintenance, are also measured and
scored. During Year 3 monitoring, the entire project reach was walked, noting geomorphic conditions
of the stream bed profile (riffle/pool facets); both stream banks, and engineered in -stream structures.
Photos were taken at every stream photograph reference station as discussed in the previous section,
and in locations of potential SPAS, which were documented in the field for subsequent mapping on the
CCPV figure if applicable. A more detailed summary of the methodology and results for the visual
stream stability assessment can be found in Appendix B, which includes supporting data tables, and
SPA photos if applicable.
2.3 Vegetation Assessment
In order to determine if success criteria are achieved, vegetation -monitoring quadrants were installed and are
monitored annually across the Site in accordance with the CVS-NCEEP Protocol for Recording Vegetation,
Version 4.1 (2007). The vegetation monitoring plots are a minimum of two percent of the planted portion of
the Site, with six plots established randomly within the planted UTIa, UT lb and UTIc riparian buffer areas per
Monitoring Levels 1 and 2. No monitoring quadrants were established within the undisturbed wooded areas of
UT 1 a and UT lb. The sizes of individual quadrants are 100 square meters for woody tree species.
Additionally, the existing vegetation areas were visually monitored during the annual site visits to document
any mortalities. Following Year 3 monitoring, it is reported that one vegetation plot (Plot 3) did not meet the
Year 3 success criteria of 320 stems per acre. The monitoring data found that Plot 3 had 243 planted stems per
acre. However, volunteer monitoring in Plot 3 had found six additional natural stems within the plot boundaries,
making the actual stem density of Plot 3, 486 stems/acre. It is also noted, that the stem density of Plot 3 exceeds
the required Year 7 density of 210 stems per acre as stated in the site's mitigation plan.
Invasive species areas of concern were observed and documented accordingly during Year 3. During, Year 3
monitoring, four areas (Areas 1, 2, 3, 4) totaling approximately 1.48 acres of the planted area were found to
contain the invasive species, Chinese privet (Lugustrum sinense). The 1.48 -acre area of privet was treated in
October and November by mechanical removal and the use of the herbicide Glyphosate. These areas are
scheduled to be treated again in 2017 during the appropriate treatment window.
At this time, no other areas of concern regarding the existing vegetation was observed along UTIa, UTIb or
UT 1 c. Year 3 vegetation assessment information is provided in Appendix B and C.

' As stated in the Special Notes section of the Excutive Summary: the US Army Corps of Engineers declined to release the
credits generated from Year 2 (2014) citing too short of a period between plant installation and monitoring following
construction. As such, this report (2016) will be considered Year 3. All references to Year 3 included in this report will
indicate monitoring activities conducted during 2016. Data collected during 2014 that was previously considered monitoring
Year 2 is labeled as Year 2*

* Harman, W.A., G.D. Jennings, J.M. Patterson, D.R. Clinton, L.O. Slate, A.G. Jessup, J.R. Everhart, and R.E. Smith. 1999.
Bankfall hydraulic geometry relationships for North Carolina streams. Wildland Hydrology. AWRA Symposium Proceedings. D.S. Olsen and J.P. Potyondy, eds.
American Water Resources Association. June 30 -July 2, 1999. Bozeman, MT.
1 Existing conditions survey data is compiled for the entire UTI Reach within the project limits.
2 Bulk samples taken since pebble count procedure is not applicable for sand -bed streams.
3 Values were chosen based on sand -bed reference reach data and past project evaluations.
4 Composite reference reach information from Johannah Creek, Johnston County; Panther Branch, Brunswick County; Rocky Swamp, Halifax County; and Beaver Dam Branch, Jones County

Flow success criteria for the Site is stated as: A surface water flow event will be considered perennial
when the flow duration occurs for a minimum of 30 days.
2016 flow data reported is 3/10/2016 to 12/2/2016. Data from loggers before 3/10/2016 was not
retreivable from data loggers due to an unkown logging issue. Logging issue has been resolved.
