1.0 Proiect Summary
1.1 Project Location and Description
The Dairyland Stream Mitigation Site (the "Site") is located within a watershed dominated by agricultural
and residential land use in Orange County, North Carolina, about eight miles Southwest of Hillsborough.
The project area exhibited diminished hydrology and habitat value as a result of past and on-going
agricultural activities. The project involved the restoration, enhancement, and protection of streams in the
Cape Fear River basin.
The project lies within the Haw River Basin and Jordan Lake Watershed (8 -digit USGS HUC 03030002,
14 -digit USGS 03030002050030). The project watershed is primarily characterized by agriculture, forests,
and low -intensity residential areas.
The total easement area is 28.6 acres. Adjacent fields are dominated by corn and soybeans. Vegetation
around the ponds and the unbuffered stream reaches (HBI, HB2, and UT2) was primarily composed of
herbaceous vegetation and scattered trees. The existing farm ponds offered little habitat to support aquatic
life, and the riparian buffers were not maximizing their potential to filter nutrients.
The Site will be monitored on a regular basis and a physical inspection of the site will be conducted at a
minimum of twice per year throughout the seven-year post -construction monitoring period, or until
performance standards are met. These site inspections will identify site components and features that require
routine maintenance. The measure of stream restoration success will be documented by bankfull flows and
no change in stream channel classification. The measure of vegetative success for the site will be the
survival of at least 210 seven-year old planted trees per acre at the end of year seven of the monitoring
period.
Upon approval for closeout by the Interagency Review Team (IRT), the site will be transferred to Unique
Places to Save (UP2S), an approved third parry long-term steward. The long-term steward will be
responsible for periodic inspection of the site to ensure that restrictions required in the Conservation
Easement or the deed restriction document(s) are upheld. Easements will be stewarded in general
accordance with the guidelines published by the National Land Trust Alliance. These guidelines include
annual monitoring visits to easements and related communication with the landowner(s).
1.2 Project Goals and Objectives
The North Carolina Division of Mitigation Services (DMS) develops River Basin Restoration Priorities
(RBRP) to guide its restoration activities within each of the state's 54 hydrologic units. The 2009 Cape
River Basin RBRP identified several restoration needs for the entire Cape River Basin, as well as for
hydrologic unit code (HUC 03030002), specifically. To satisfy these needs RES has established the RES
Cape Fear 02 Umbrella Mitigation Bank, with the first approved bank site being the Dairyland Mitigation
Site.
The Site is located within the Haw River, the major river in HUC 03030002. This river and its tributaries
flow to B. Everett Jordan Lake, a drinking water supply. This supply has been designated a Nutrient
Sensitive Water and NC Division of Water Resources (DWR) has developed a set of goals to reduce non -
point source pollution in its watershed. Goals include promoting nutrient and sediment reduction in
agricultural and urban areas by restoring and preserving streams, wetlands, and riparian buffers. The Site
provides compensatory mitigation for impacts on the Waters of the US under the Section 404 of the Clean
Water Act.
Dairyland 1 Baseline Monitoring Report
Stream Mitigation Site October 2019
Project goals will be addressed through the following project objectives:
• Dam breach and pond removal,
• Restoration of appropriate pattern, dimension, and profile in stream channels.
• Restoration of forested riparian stream buffers,
• Enhancement of hydrology and vegetation in existing riparian wetlands,
• Treatment and control of exotic invasive species,
• Stabilization of eroding stream banks due to lack of vegetation, and
• Addition of large woody debris, such as log vanes, log weirs, root wads.
Due to its location and improvements, the Site provides numerous ecological and water quality benefits
within the Cape Fear River Basin. While many of these benefits are limited to the project area, others, such
as pollutant removal and improved aquatic and terrestrial habitat, have farther -reaching effects. Many of
the project design goals and objectives, including restoration of riparian buffers to filter runoff from
agricultural operations, improvement of terrestrial habitat, and construction of in -stream structures, address
the degraded water quality and nutrient input stressors identified as major watershed stressors in the 2009
Cape Fear RBRP.
1.3 Project Success Criteria
The Site follows the USACE 2003 Stream Mitigation Guidelines and the "Wilmington District Stream and
Wetland Compensatory Mitigation Update" dated October 24, 2016. Cross section and vegetation plot data
will be collected in Years 0, 1, 2, 3, 5, and 7. Stream hydrology data and visual monitoring will be reported
annually.
Stream Success Criteria
Four bankfull flow events must be documented within the seven-year monitoring period. The bankfull
events must occur in separate years. Otherwise, the stream monitoring will continue until four bankfull
events have been documented in separate years.
There should be little change in as -built cross-sections. If changes do take place, they should be evaluated
to determine if they represent a movement toward a less stable condition (for example down -cutting or
erosion), or are minor changes that represent an increase in stability (for example settling, vegetative
changes, deposition along the banks, or 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. Bank height ratio shall not exceed
1.2, and the entrenchment ratio shall be no less than 1.4 within restored reaches. Channel stability should
be demonstrated through a minimum of four bankfull events documented in the seven-year monitoring
period.
Digital images will be used to subjectively evaluate channel aggradation or degradation, bank erosion,
success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images should
not indicate the absence of developing bars within the channel or an excessive increase in channel depth.
Lateral images should not indicate excessive erosion or continuing degradation of the banks over time. A
series of images over time should indicate successional maturation of riparian vegetation.
Dairyland 2 Baseline Monitoring Report
Stream Mitigation Site October 2019
Vegetation Success Criteria
Specific and measurable success criteria for plant density within the riparian buffers on the Site will follow
IRT Guidance. Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover a minimum
of two percent of the planted area. Vegetation monitoring will occur between July 1St and leaf drop and
includes 11 permanent vegetation plots and four random vegetation plots. The interim measures of
vegetative success for the site will be the survival of at least 320 planted three-year old trees per acre at
the end of Year 3, 260 five-year old trees at the end of Year 5, and the final vegetative success criteria
will be 210 trees per acre with an average height of 10 feet at the end of Year 7. Volunteer trees will be
counted, identified to species, and included in the yearly monitoring reports, but will not be counted
towards the success criteria of total planted stems.
1.4 Project Components
Mitigation credits presented in these tables are based upon site design in the approved final mitigation plan.
SMIJ totals were adjusted and calculated using the most recent non-standard buffer width guidance. The
stream mitigation components are summarized in Table 1, as well as Figure 2.
*SMUs are adjusted in accordance with Section XI(C)- "Procedures to Calculate Credits for Non-standard Buffer Widths",
published in the October 2016 Wilmington District Stream and Wetland Compensatory Mitigation Update. A detailed description
of the methodology and calculations is described in the Approved Mitigation Plan.
1.5 Design/Approach
The design approach for the Site was to combine the analog method of natural channel design with
analytical methods to evaluate stream flows and hydraulic performance of the channel and floodplain. The
analog method involves the use of a "template" stream adjacent to, nearby, or previously in the same
location as the design reach. The template parameters of the analog reach are replicated to create the features

of the design reach. The analog approach is useful when watershed and boundary conditions are similar
between the design and analog reaches (Skidmore, et al., 2001). Hydraulic geometry was developed using
analytical methods in an effort to identify the design discharge.
Priority Level I Restoration was performed on Reaches HB -2 and UT -2, both of which were farm ponds.
Restoration activities included draining and breaching the existing impoundments and constructing
channels once the ponds had been breached. A combination of Priority I Restoration and Enhancement
Level II was performed along the primary project channel (Reaches HB -1 and HB -2) to address existing
impairments, particularly impoundment, floodplain disconnection, and buffer degradation. Enhancement
III was performed on Reaches UT -1 and WF -2, as the channel is stable throughout, regularly accesses its
floodplain and provides a variety of aquatic habitats. Preservation was performed for Reach WF -1. The
channel is stable throughout, regularly accesses its floodplain and provides a variety of aquatic habitats.
1.6 Construction and As Built Conditions
Stream construction was completed in August 2018 and planting was completed in November 2018. The
Dairyland Mitigation Site was built to design plans and guidelines. Baseline channel length and stationing
is based on design centerline. The only notable change that was made during construction was changing
the crossing between HB -1 and HB -2 from a culvert to a ford. This modification, which is outside of the
conservation easement area, was made based on the large amount of bedrock unearthed after the ponds
were dewatered. The design engineer drafted and sealed a bulletin drawing to retain the bedrock features
and tie-in with the downstream stream design as shown in the Mitigation Plan. The bulletin is included in
Appendix F. Also, a few log structures were removed from the design to utilize the existing bedrock found
in the new channel location and retained the designed channel slope. Following Hurricane Florence and
Hurricane Michael, the stream construction contractor added rip rap material around the grade control
structures from 7+00 to 9+00 on UT -2. During the As -Built Site Visit with the IRT on November 29, 2018,
RES agreed that the amount of rip rap material was not appropriate for the design. Shortly after the site
visit, RES removed the rip rap from the areas not directly around structures. Two other areas that were
identified during this site visit included two small encroachment areas along WF -2 and the general comment
to treat invasive species in the WF -2 easement area.
1.7 Monitoring Performance (MY1)
The Monitoring Year 1 (MY1) activities were completed in August 2019. All monitoring data is present
below and in the appendices. The Site is on track to meet vegetation and stream interim success criteria.
Vegetation
Monitoring of the 11 permanent vegetation plots and four random vegetation plots was completed during
August 2019. Vegetation data are in Appendix C, and associated photos and plot locations are in Appendix
B. MY1 monitoring data indicates that all plots are exceeding the interim success criteria of 320 planted
stems per acre. Planted stem densities ranged from 445 to 1,012 planted stems per acre with a mean of 736
planted stems per acre across the permanent plots. A total of 15 species were documented within the plots.
Volunteer tree species were found in over half of the plots. The average tree height observed in the
permanent vegetation plots was 2.2 feet. Data from the four random vegetation plots showed 526 stems/acre
in Random Plot 1, 324 stems/acre in Random Plot 2, 1,133 stems/acre in Random Plot 3, and 971 stems/acre
in Random Plot 4. The average height in the random vegetation plots was 3.4 feet.
Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is
becoming well established throughout the project. There is one low stem density area about 0.22 acres in
Dairyland 4 Baseline Monitoring Report
Stream Mitigation Site October 2019
size just south of Random Vegetation Plot 2. Additionally, there are four small areas of encroachment
totaling 0.19 acres where the easement has been moved/driven through. RES will contact the landowner
about these areas as well as install additional easement markers in MY2.
Stream Geomorphology
Geomorphology data for MY1 was collected during August 2019. Summary tables and cross section plots
are in Appendix D. Overall, the cross sections relatively match baseline condition. Minor adjustments are
expected in the first few years after construction.
Visual assessment of the stream channel was performed to document signs of instability, such as eroding
banks, structural instability, or excessive sedimentation. The channel is transporting sediment as designed
and will continue to be monitored for aggradation and degradation.
Stream Hydrology
There are two stage recorders on site, one on Reach HB -2 and one on Reach UT -2. Automatic pressure
transducers were not added to the stage recorders until August 2019 so there are only visual bankfull
readings for MY I. There was a 1.3' wrack line at the stage recorder on HB -2 and a 2.2' corkline reading at
the stage recorder on UT -2. According to local rainfall data these bankfull events most likely occurred in
April 2019. Gauge locations are shown on Figure 2 and photos are in Appendix B.
2.0 Methods
Stream monitoring was conducted using a Topcon GTS -312 Total Station. Three-dimensional coordinates
associated with cross-section data were collected in the field (NAD83 State Plane feet FIPS 3200).
Morphological data were collected at 16 cross-sections. Survey data were imported into CAD, ArcGIS®,
and Microsoft Excel® for data processing and analysis. The stage recorders include a flow gauge and a crest
gauge. The flow gauges were installed within the channel and will record flow conditions at an hourly
interval. The crest gauges were installed on the bank at the bankfull elevation. During quarterly visits to the
Site, the height of the corkline will be recorded. HOBO data from the flow gauges will be corrected using
bankfull recordings from the crest gauges.
Vegetation success is being monitored at 11 permanent monitoring plots and four random monitoring plots.
Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol 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 metal conduit at the other corners. Photos of each plot are to be taken from the
origin each monitoring year. The random plots are to be collected in locations where there are no permanent
vegetation plots. Random plots will most likely be collected in the form of a 100 square meter belt transect.
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.
