RE: Gideon Year 3 Monitoring Report (SAW-2017-01462) | RES Yadkin 01 Umbrella Mitigation
Bank

Dear Mr. Kichefski,

Please find attached the Gideon Year 3 Monitoring Report.

In Year 3, all four vegetation plots met the 320 stems per acre success criteria. The average planted
stems per acre was 951 and the average planted stem height was 4.7 feet. Livestakes are becoming
well established along the stream banks throughout the site. Cr oss section plots were stable when
compared to as-built conditions. Both stage recorders documented bankfull events and the flow
gauge documented 219 consecutive days of flow. The three wetland gauges recorded
hydroperiods in the range of five to 60 percent. In 2022, headcuts were observed along the top
of bank near cross section three and four. These areas were repaired using haybales, coir matting,
seeding, and livestaking in May 2023. Photos of the repairs are included in the report.

Please see the IRT comments received on December 28, 2022 with RES’ responses below:

Erin Davis (NCDWR) comments:

1. Please include photos of the 2022 headcut repairs in the MY3 report. DWR is concerned that
haybale placement on the bank may be only a temporary fix/band-aid.
Photos are included in Appendix B.

2. DWR appreciated the level of detail provided in the narrative, CCPV callouts and graphs.
Noted.

DWR is not requesting a site visit. We support the proposed credit release.

Gideon Mitigation Site 1 Year 3 Monitoring Report
Surry County, NC August 2023
1.0 Project Summary
1.1 Project Location and Description The Gideon Project (“Project”) is located within a rural watershed in Surry County, North Carolina
approximately 10 miles north of Elkin. Water quality stressors affecting the Project prior to restoration included livestock production, agricultural practices, and lack of riparian buffer. The Project presents stream
restoration, enhancement, and preservation, generating 2,962.067 Cool Stream Mitigation Units (SMU). The Project’s total easement area is 11.23 acres within the overall drainage area of 3,225 acres. The Project
is between two separate portions of the Division of Mitigation Services (DMS) Little Sebastian Site. While each site could be developed independently of the other, the combined easements will result in a much larger contiguous protected corridor and high-quality aquatic habitat. The Little Sebastian Site has a total easement area that is approximately 25.90 acres and presents 8,068 LF of stream restoration, enhancement, and preservation. Therefore, a total of 37.13 acres and 12,850 LF of stream will be protected in perpetuity
when combining the totals on Little Sebastian and Gideon. Grazing livestock have historically had access to most stream reaches within the Project. The lack of riparian buffer vegetation, deep-rooted vegetation, and unstable channel characteristics have contributed to the degradation of stream banks throughout the Project area. The stream design approach for the Project 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 involved the use of a reference reach, or “template” stream, adjacent to, nearby, or previously in the same location as the design reach. The template parameters of the analog reach were 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 to identify the design discharge. The Project has been constructed and planted and will be monitored on a regular basis throughout the seven-year post-construction monitoring period, or until performance standards are met. The Project will be transferred to Unique Places to Save (UP2S). This party shall serve as conservation easement holder and long-term steward for the property and will conduct periodic inspection of the site to ensure that restrictions
required in the conservation easement are upheld. Funding will be supplied by the responsible party on a yearly basis until such time an endowment is established.
1.2 Project Goals and Objectives
Through the comprehensive analysis of the Project’s maximum functional uplift using the Stream Functions Pyramid Framework, specific, attainable goals and objectives will be realized by the Project. These goals
clearly address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2009 Upper Yadkin Pee-Dee River RBRP. These goals and objectives reflect those stated in the Gideon Project Final Mitigation Plan.
The Project goals are:
• Improve water transport from watershed to the channel in a non-erosive manner in a stable channel;
• Improve flood flow attenuation on site and downstream by allowing for overbanks flows and connection to the active floodplain;

Gideon Mitigation Site 2 Year 3 Monitoring Report
Surry County, NC August 2023
• Improve instream habitat;
• Restore and enhance native floodplain vegetation; and
• Indirectly support the goals of the 2009 Upper Yadkin Pee-Dee RBRP to improve water quality and
to reduce sediment and nutrient loads. The Project goals were addressed through the following project objectives:

• Designed and reconstructed stream channels sized to convey bankfull flows that maintain a stable dimension, profile, and planform based on modeling, watershed conditions, and reference reach conditions;
• Permanently excluded livestock from stream channels and their associated buffers;
• Added in-stream structures and bank stabilization measures to protect restored and enhanced streams;
• Installed habitat features such as brush toes, constructed riffles, woody materials, and pools of varying depths to restored and enhanced streams;
• Reduced bank height ratios and increased entrenchment ratios to reference reach conditions;
• Increased forested riparian buffers to at least 30 feet on both sides of the channel along the Project reaches with a hardwood riparian plant community;
• Treated exotic invasive species; and
• Established a permanent conservation easement on the Project.
Functional uplift, benefits, and improvements within the Project area, as based on the Function Based Framework, are outlined in the Final Mitigation Plan.
1.3 Project Success Criteria
The success criteria for the Project follows the 2016 USACE Wilmington District Stream and Wetland Compensatory Mitigation Update, the Gideon Final Mitigation Plan, and subsequent agency guidance. Cross
section and vegetation plot monitoring takes place in Years 0, 1, 2, 3, 5, and 7. Stream hydrology and visual monitoring takes place annually. Specific success criteria components are presented below. Stream Restoration 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. For C/E channels, bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less than 2.2 within restored reaches. For B channels, 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.

Gideon Mitigation Site 3 Year 3 Monitoring Report
Surry County, NC August 2023
Digital images are 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.
Stream restoration reaches will be monitored to document intermittent or seasonal surface flow. This will be accomplished through direct observation and the use of stream gauge transducers with data loggers. Reaches must demonstrate a minimum of 30 consecutive days of flow. Vegetation Success Criteria
Specific and measurable success criteria for plant density within the riparian buffers on the Project will follow IRT Guidance. The interim measures of vegetative success for the Project will be the survival of at
least 320 planted three-year old trees per acre at the end of Year 3, five-year old trees at six feet in height at the end of Year 5, and the final vegetative success criteria will be 210 trees per acre with an average height of eight 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. Moreover, any single species can only account for up to 50 percent of the required
number of stems within any vegetation plot. Any stems in excess of 50 percent will be shown in the monitoring table but will not be used to demonstrate success.
1.4 Project Components
The Project area is comprised of a single 11.23-acre easement location along Mill Creek and three unnamed tributaries, totaling 4,782 LF, which eventually drain into the Yadkin River.
Through stream restoration, enhancement, and preservation, the Project presents 4,782 LF of proposed stream, generating 2,962.067 Cool SMUs. The stream mitigation components are summarized below. Mitigation credits presented below are based upon the Approved Mitigation Plan.

Total 4,782 2,962.067

1.5 Stream Design/Approach The stream component of the Project included priority I stream restoration, enhancement I, enhancement III, and preservation. Stream restoration incorporated the design of a single-thread meandering channel,
with parameters based on data taken from reference sites, published empirical relationships, regional curves developed from existing project streams, and NC Regional Curves. Analytical design techniques were also a crucial element of the project and were used to determine the design discharge and to verify design stability.

1.6 Construction and As-Built Conditions
Stream construction was completed in February 2021 and planting was completed in March 2021. The Gideon Project was built to design plans and guidelines with no significant changes during construction.
The as-built survey and record drawings are included in Appendix E. Planting plan changes included replacing blackgum (Nyssa sylvatica) and elderberry (Sambucus canadensis)
with sugarberry (Celtis laevigata) and buttonbush (Cephalanthus occidentalis). These changes were based on bare root availability. A planted species summary is included in Appendix C.
1.7 Monitoring Performance (MY3)
The Gideon Year 3 monitoring activities were performed in June and August 2023. All year three monitoring data is present below and in the appendices. The Project is on track to meeting vegetation and stream interim success criteria.
Vegetation

Monitoring of four fixed vegetation plots was completed on August 8, 2023. Vegetation data are in Appendix C, associated photos are in Appendix B, and plot locations are in Appendix B. MY3 monitoring
data indicates that all plots are exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 405 to 1,376 planted stems per acre with a mean of 951 planted stems per acre across all plots. A total of 11 planted species were documented within the plots. Volunteer species were
noted in two of the plots. The average stem height in the plots was 4.7 feet. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project. Volunteer tag alder (Alnus serrulata) and black willow (Salix nigra) have established and are flourishing throughout the Project area, likely spreading from the
now-mature livestakes. Areas of Chinese privet (Ligustrum sinense) and multiflora rose (Rosa multiflora) were

Surry County, NC August 2023
treated along JN4-A, JN5, JN6-C, and MC2-B in May 2023; no additional areas of invasive species were
observed during MY3 monitoring. The fencing and gates were all in good condition throughout the site and no encroachment was observed.
Stream Geomorphology
Geomorphology data for MY3 was collected in June 2023. Summary tables and cross section plots are in
Appendix D. Overall, the Year 3 cross sections and profile relatively match the proposed design. The MY3 conditions show that shear stress and velocities have been reduced for the restoration reaches. These
reaches were designed as coarse gravel to cobble bed channel and remain classified as a coarse gravel to cobble bed channel post-construction.
Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. A few areas of head-cutting were observed along MC2-A during MY2 monitoring, most likely a result of overland flow. These areas were repaired in May 2023 using haybales, coir matting, seeding, and livestaking. Documentation of the repairs can be found in Appendix B. The channel is transporting sediment as designed and will continue to be monitored for aggradation and degradation. Stream Hydrology
Two stage recorders (on MC2-A and JN6-C) and one flow gauge (on JN6-B) were installed in March 2021
and document bankfull events and flow days, respectively. Both gauge types record readings at a frequency of once per hour, 24 hours per day. The stage recorder on JN6-C documented one bankfull event on July 29, 2023, measuring 0.09 feet above the top of bank. The stage recorder on JN6-C documented one bankfull
event on July 29, 2023, measuring 0.09 feet above the top of bank. The stage recorder on MC2-A measured two bankfull events, with the highest one on July 29, 2023, measuring 0.11 feet above the top of bank. A picture of this bankfull event (July 29, 2023), captured by a flow camera installed upstream of MC2-A on the Little Sebastian easement has been included in Appendix B. The photo was taken at 6:45pm on July 29, however, the stream data shows that the actual bankfull event occurred earlier that day, sometime closer to 12:00pm. The flow gauge documented one flow event, lasting 219 days. All recorded streams are on track to pass hydrology metrics. Stream hydrology data is included in Appendix E. Gauge locations can be found
on Figure 2 and photos are in Appendix B. Wetland Hydrology
Three groundwater wells with automatic recording pressure transducers were installed in March 2021. The goal of the groundwater wells is to track the hydrology of the jurisdictional wetlands on site post-
construction. There is no hydroperiod success criteria for these groundwater wells. During MY3 groundwater well 1 (GW1) had a 5% hydroperiod. In MY2, this well was found snapped in half and was replaced on November 2, 2022. Groundwater well 2 (GW2) had a 60% hydroperiod, and groundwater well 3 (GW3) had an 18% hydroperiod. Wetland hydrology data can be found in Appendix E and gauge locations can be found on Figure 2.

Gideon Mitigation Site 7 Year 3 Monitoring Report
Surry County, NC August 2023
2.0 Methods Stream cross section 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 10 cross-sections. Survey data were imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. The stage recorder (JN6-C) and flow gauge (JN6-B) include an automatic pressure transducer placed in PVC casing in a pool. The elevation of the bed
and top of bank at each stage recorder are used to detect bankfull events and the elevation of the bed and crest of the downstream riffle at the flow gauge is used to detect flow days. Due to the large size of the channel on MC2-A, the stage recorder was installed with the transducer equal to the top of bank elevation. This means any positive reading should be a bankfull event. However, there are a number of insignificant positive readings, less than 0.1 feet, so only events greater than 0.1 feet were reported. Vegetation success is being monitored at four fixed 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. Wetland hydrology is monitored to track the hydrology of the jurisdictional wetlands on site post-construction. This is accomplished with three automatic pressure transducer gauges (located in
groundwater wells) that record daily groundwater levels. 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.
