Reference to Little Pine III has been removed from section 1.2. • Project Goals and Objectives — Please copy -and -paste Table 1. Project Goals and Objectives from the 2016 Mitigation Plan Addendum, and indicate it is from that document. Keep the first paragraph and replace the rest with the table. The Project Goals and Objectives table has been updated and the narrative indicates it is from the 2016 Mitigation Plan Addendum. Additional text has been removed. 37 Haywood Street, Suite 100 Asheville NC 28801 828.253.6856 www.equinoxenvironmental.com __4W EQU I NOX balance through properplonning • Section 2.11 - Remove sentence about the DMS approval. The IRT Approval should be indicated in Table 2 as February 2016. Sentence about DMS approval removed. IRT Approval indicated in Table 2 as February 2016. • There are two sections labeled 2.3.1. Please correct. Section labels corrected. • Section 2.3 — Wetlands are being tracked by NCDMS as riparian, non-riverine. Please adjust text as necessary. Also, preservation is discussed as having livestock fencing. The livestock exclusion is more pertinent to the restoration segments across the project. Text corrected to indicate the wetlands are being tracked as riparian, non-riverine. Discussion about livestock exclusion moved to the more pertinent portion of the report. • Please indicate in Section 2.4 that a memo dated September 9, 2019 from DMS to the IRT indicated updated performance standards, monitoring plan, and 7-year credit release schedule. Please reference and include the memo in an Appendix (email attachment to this letter). In addition, please note that a site meeting was then held on 111512019, and reference/include that memo (also attached) in the Appendix. Text changed to indicate relevant performance standards, monitoring plan, and 7-year credit release schedule and the associated memo. That memo and site meeting memo were added to the Appendix. • Section 3.0 - Please verify and indicate that listed performance criteria reflect the memo dated September 9, 2019 from DMS to the IRT (as you did for the monitoring). Sentence added to indicate listed performance criteria reflect the aforementioned memo from DMS to the IRT. • As Built Data Documentation —please add detail indicating the reach by reach reasons, e.g., geolift structure installed at LPC STA 100+00 to assist in sediment transport following Fall 2018 Florence and Michael storm damages; Trib C tie in to LPC adjusted, etc. Detail added for alignment deviations. Please verify and indicate that monitoring features and locations reflect the September 2019 IRT memo, or indicate where different (and why). For example, please indicate why Cross sections 1 and 2 were chosen at different locations than planned. Cross sections should be at reach -specific representative riffle -pool locations. Other features and locations appear to reflect the memo, with insignificant variations, but please verify. Language added to indicate that monitoring features and locations mostly reflect the September 2019 IRT memo except for Cross Sections 1 and 2. An explanation for that deviation is provided. • Typo in Pattern section — M7. Typo corrected. • 4.2.1 Vegetation (and CCPV) —Only quite obvious areas devoid of woody stems should be mapped as low stem density, the site is young and as you indicate, the assessments were made during dormant season. 37 Haywood Street, Suite 100 Asheville NC 28801 828.253.6856 www.equinoxenvironmental.com EQUINOX bofance through properpionning Low stem density polygons revised to indicate those areas most devoid of woody stems. These areas are primarily those affected by a greater than bankfull event between planting and monitoring. • References —spelling typo 'Projection" (last entry) Typo corrected. Table 1— if there are no cool credits, please remove the 0.000. "0.000" removed • Table 2 — Project "Initiation Date" should be Project "Institution Date" and listed at 1212112007. Indicate both month and year for completion or delivery. "Draft Design Plan" and "Final Design Plan" are not needed here, as Restoration Plan is already indicated. Please note that substantial completion for construction grading was approved May 21, 2019, this (May 2019) should be the Construction complete month -year. Please also revise the Planting Date, planting was completed between 41212019 and 4/8 2019 so Planting Complete should be April 2019. Project "Initiation Date" changed to Project "Institution Date" and listed at 12/21/2007. • Table 3 — Project designer is Jeff Keaton, Wildlands; Planting contractor is Carolina Silvics (Mary Margaret McKinney) Project contractor and contacts updated accordingly. Maps — CCPV, Assets/Components, and Monitoring features should all be combined, and split into 3 detail maps (Generally, LPC Reach 1, Reach 2A, and Reach 28 and surrounding areas). These are typically called "Integrated CCPV" Sheet 1, 2, etc. Zooming in will allow all features to be included on each sheet, enable a better resolution, and avoid redundancy. An overall CCPV sheet with the 3 sheets keyed out with an overlay would work well, so as follows: o Little Pine Creek 11 Stream and Wetland Mitigation Site (Key). o Little Pine Creek 11 Integrated Current Condition Plan View (Sheet 1) o Little Pine Creek 11 Integrated Current Condition Plan View (Sheet 2) o Little Pine Creek 11 Integrated Current Condition Plan View (Sheet 3) CCPV, Assets/Components, and Monitoring features combined on reach scale detail maps. • Constructed vernal pools should be added to the CCPVs. Constructed vernal pools were added to the CCPVs. CVS table —At construction close out, the designer certified that the site was planted at 605 stems per acre (4665 bare roots / 7.7 acres), per the construction contract (bid addendum 03, dated 912812017); the site wide stem density (273 stems/acre) indicates high mortality or below the planting density requirement. Did Equinox find that the plots had planted stems that died, or just were not present in the specified planted density? Equinox notes (Sec 4.2.1) that field conditions during the assessments were made in conditions not favorable for identifying planted stems. What field conditions? Can Equinox advise on why the MYO numbers might be below success criteria? Equinox did not identify dead stems in the plots; stems were not present. Snow cover of approximately 3-4" and recent alluvial deposition were the field conditions which were unfavorable for assessment. Stems could have been covered by alluvial deposition or removed by high flows. 37 Haywood Street, Suite 100 Asheville NC 28801 828.253.6856 www.equinoxenvironmental.com __4W EQU I NOX balance through properplonning • Please add all common names to CVS table. Common names added to CVS table. • The wetland planting zones had a few additional species on the wetland zone planting list, not reflected in the CVS table (Sambucus, Lindera, Quercus, Nyssa, etc). Were these not found in VP2 or VP6 (wetland plots)? All species which were found within the vegetation monitoring plots are included in the CVS table. • Table 6 - Planted acreage should not reflect disturbed acreage associated with vernal pools. Disturbed and planted acreage was 7.7 acres when vernal pools are accounted for. Also, two red footnotes appear unreferenced. This table should be formatted to letter size. Please see prior comment on low stem density area determination and mapping. Disturbed and planted acreage area adjusted to 7.7 acres. Two red footnotes removed. Table formatted to letter size.

Location and Setting The Site is located in eastern Alleghany County, NC as shown in Figure 1. The Site is approximately eight miles east of the Town of Sparta, NC and approximately four miles south of the Virginia border. (Figure 1). The Site is located in the New River Basin; eight -digit Cataloging Unit (CU) 05050001 and the 14-digit Hydrologic Unit Code (HUC) 05050001030030 (Figure 1). Located in the Blue Ridge Belt of the Blue Ridge Province (USGS, 1998), the project watershed includes primarily managed herbaceous, mixed upland hardwoods, and other forested land. The drainage area for the Site is 2,784 acres. The North Carolina Division of Water Resources (DWR) assigns best usage classifications to State Waters that reflect water quality conditions and potential resource usage. Little Pine Creek (DWR Index No. 10-9- 10-5) is the main tributary of the project and is classified as Class C waters. Class C waters are protected for secondary recreation, fishing, wildlife, fish and aquatic life propagation and survival, agriculture, and other uses. Little Pine Creek also has a supplemental classification as Trout Waters (Tr). Trout waters are protected to sustain and allow for trout propagation and survival and include tributaries to stocked trout streams. Trout are not currently stocked in Little Pine Creek. Brush Creek, which is located downstream of the Site, is hatchery supported. The Site is located within a TLW in the New River RBRP plan (NCDENR, 2009), and is identified in the Little River and Brush Creek LWP Project Atlas (NCDENR, 2007). The Little River and Brush Creek LWP identified the following stressors in the watershed: unforested buffers that are heavily grazed, livestock access to streams, heavily eroded stream banks, land -disturbing activities on steep slopes, and storm water runoff in and around the town of Sparta. The LWP Project Atlas identified the Little Pine Creek II Stream and Wetland Restoration Project (LPC1-04, LPC1-W10) as a stream and wetland restoration opportunity with the potential to improve water quality, habitat, and hydrology within the Brush Creek watershed. Prior to construction activities, livestock had full access to most of the Site streams and used them as a water source. The riparian buffers in areas proposed for restoration were primarily herbaceous with a few sparse trees. Deposition of fine sediment, severe bank erosion, and trampling of banks, impacted the in -stream habitat. Channel widening and incision indicated instability. Table 1 in AppendixA and Table 7 in Appendix D present the pre -restoration conditions in detail. Little Pine Creek II Baseline Monitoring Document NC DMS Project No 856 1 Equinox Little Pine Creek II Baseline Monitoring Document NC DMS Project No 856 2 Equinox L2, Goals and Objectives The LPC II Site is intended to provide numerous ecological benefits within the New River Basin. While many of these benefits are limited to the Little Pine II project area, others, such as pollutant removal, reduced sediment loading, and improved aquatic and terrestrial habitat, have farther -reaching effects. Expected improvements to water quality and ecological processes are outlined below as project goals and objectives. These project goals were established with careful consideration of goals and objectives that were described in the RBRP and to address stressors identified in the LWP. Below is the Project Goals and Objectives table from 2016 Mitigation Plan Addendum. r Goal objective Expected Outcomes Create and improve forested riparian habitats.

Little Pine Creek II Baseline Monitoring Document NC DMS Project No 856 3 Equinox 2.0 PROJECT ATTRIBUTES 2.1. Project Structure Construction activities were completed in June 2019 by Wright Contracting, LLC. Turner Land Surveying completed the as -built survey in July 2019 and Equinox completed the baseline monitoring activities in January 2020. Planting was completed by Wright Contracting, LLC in June 2019. Final monitoring activities and closeout will commence in December 2026. Minimal adjustments were made during construction and field adjustments made during construction are described in further detail in section 4 Please refer to Appendix for detailed project activity, history, contact information, and watershed/site background information. 2.2. Mitigation Components The LPC II Site is expected to provide 3,281.6 SMUs and 1.47 WMUs. The components and mitigation credits reflect the as -built condition of the site as represented in the Turner Land Surveying as -built survey. Refer to the Project Assets Map (Figure 2) for the stream and wetland features and table 1 for the project component, assets, and mitigation credit information for the LPC II Site. 2.3. Restoration Type and Approach 2.3.1 Streams The project includes stream restoration and preservation as well as wetland enhancement and preservation. The specific proposed stream and wetland types are described below. The stream restoration portion of the Site includes six reaches; three reaches on Little Pine Creek, one reach on Tributary A, one reach on Tributary B, and one reach on Tributary C. The stream restoration design was developed based on reference conditions, representing streams within the Blue Ridge Belt region with similar drainage areas, valley slopes, morphology, and bed material. The design streams were restored to the appropriate type based on the surrounding landscape, climate, and natural vegetation communities and with thorough consideration to the existing watershed conditions and their trajectory. Fencing is installed to ensure livestock exclusion. The preservation portion of the Site includes Tributaries D, E, and F. The preservation reaches are preserved as -is because they are stable and flow through mature forest. 2.3.2.Wetlands The wetland portion of the LPC II Site includes three wetland zones. Wetland 1 is a riparian, non-riverine wetland enhancement zone. Wetland 2A is a riparian, non-riverine wetland enhancement zone. The enhancement activities included supplemental planting and fencing to remove livestock. Wetland 2B is preservation only. 2.4. Project History, Contacts and Construction Summary This project, a DMS design -bid -build project originally instituted in December 2007, has had several delays due to landowner issues, a temporary ban on trout waivers (2010), a construction contract termination and design reassignment (2013), conservation easement adjustment (2015), mitigation plan addendum (2016) and significant hurricane damage during construction (2018). The project was Little Pine Creek II Baseline Monitoring Document NC DMS Project No 856 4 Equinox built according to the January 2016 mitigation plan addendum design (Wildlands Engineering), and now has a final, sealed as -built survey dated July 14, 2019. A memorandum dated September 9, 2019 From DMS to the IRT indicated updated performance standards, monitoring plan, and 7-year credit release schedule. A site meeting with the IRT was held November 5, 2019 and a memorandum was issued regarding the meeting. Copies of the memorandums along with Tables 2, 3, and 4 are in Appendix Aand provide detailed information regarding the project schedule, project contracts, and project information and attributes. 3.0 SUCCESS CRITERIA AND MONITORING The listed performance criteria for the LPCII site was taken from the LPC II Monitoring update memorandum dated September 9, 2019 and is detailed below. 3.1. Stream Restored Stream Channels • All streams must maintain an Ordinary High -Water Mark (OHWM), per RGL 05-05. • Continuous surface flow must be documented each year for at least 30 consecutive d ays. • Bank height ratio (BHR) cannot exceed 1.2 for all measured cross sections on a given reach. • Entrenchment ratio (ER) must be above 2.2 for all measured riffle cross -sections on a given reach (for C and E streams). • BHR and ER should not change by more than 10% in any given yearfor all measured cross sections on a given reach. • Must document occurrence of at least 4 bankfull events in separate years during the monitoring period. 3.2. Vegetation Riparian Vegetation • Within planted portions of the site, a minimum of 320 stems per acre must be present at year3; a minimum of 260 stems per acre must be present at year 5; and a minimum of 210 stems per acre must be present at year 7. • Trees must average 6 feet in height at year 5, and 8 feet in height at year 7 (mountain region). • Planted and volunteer stems are counted, provided they are included in the approved planting list for the site. • Any single species can only account for 50% of the required stems per monitoring Plot. 3.3. Wetlands Performance standards are not defined for the wetland enhancement areas. Hydrologic data will be collected will not be used to evaluate success criteria for the LPC II Site. Little Pine Creek II Baseline Monitoring Document NC DMS Project No 856 5 Equinox 3.4. Monitoring Plan The monitoring plan was for the LPCI I site was taken from the LPC II Monitoring update memorandum dated September 9, 2019 and is detailed below. Cross Sections land 2 were moved upstream from the proposed locations due to infilled condition of the pool at the proposed location during the installation of the monitoring features. Cross Sections 1 and 2 were installed at a riffle and pool pair representative of the design dimensions for LPC Reach 1. All other monitoring features were installed at locations as outlined in the September 2019 IRT memo with insignificant variations.

Trib C tie in to LPC adjusted. DMS met at the site with the IRT on 11/14/2019. Tributaries E and F (50 LF and 153 LF, respectively) had been jurisdictionally confirmed, however the lower section of Tributary F had appeared to down cut since project design. The IRT indicated that, despite some stable segments of Tributary F upstream of a head cut, that recent impacts and a head cut along Tributary F have affected stream performance on these reaches to the degree that Tributaries E and F should not yield stream preservation credits. These reaches are not being credited. 4.1. Stream Morphological data forthe as -built profile was collected between November 2019 and January 2020. Please referto Appendix D forsummary data tables, morphological plots, and stream photographs. Profile The MYO profiles closely match the profile design parameters. On the design profiles, riffles were depicted as straight lines with consistent slopes. However, at some locations the riffle profiles within the as -built survey are not consistent in slope due to the installation of structures and woody debriswithin the streambed. Riffle slopes and bankfull slopes are generally within the design range. Maximum pool depths typically exceed design parameters and are expected to trend towards the design depths as a result of natural deposition overtime. These variations pool depths likely do not constitute a problem nor do they indicate a need for remedial action; they will be assessed visually during the annual assessments. Dimension The MYO dimension numbers closely match the design parameters within acceptable ranges of variation. Variations in baseline parameters are reflected in the cross- sections as a larger maximum pool depth. We anticipate that overtime pools may accumulate with sediment and organic matter. This accumulation of sediment within pools would not be seen as an indicator of instability. Maximum depth in riffles are occasionally exceeded due to micropools formingthrough lateralscour near hard features, but this is not expected to adversely impactthe stability of the channel. Little Pine Creek II Baseline Monitoring Document NC DMS Project No 856 7 Equinox Pattern The MYO pattern metrics fell within acceptable ranges of the design parameters for all three reaches. Pattern data will be evaluated in MY7 if there are any indicators through the profile or dimension assessments that significant geomorphic adjustments have occurred. Bankfull Events Bankfull events recorded following completion of construction will be reported in the MY1 report. 4.2.1 Vegetation The MYO average planted density is 273 stems per acre, which does not meetthe interim measure of vegetative success of at least 320 planted stems per acre at the end of the third monitoring year. Summary data and photographs of each plot can be found in AppendixC. It should be noted that there is a general appearance of low stem density within the Ito on the flood plain; recent flooding resulted in deposition of bed material onto the flood plain, and also much of the floodplain vegetation being laid over horizontally in a downstream direction. Furthermore, recent snowfall on the ground surface and temperatures around 10°F made it difficult to locate planted stems amongst other frozen vegetation. 4.2.2 Wetlands Groundwater gage data will be reported in the annual MY1 and subsequent monitoring reports.

Ym SEAL 11027 CONSTRUCTION SEQUENCE: Channel Construction Notes for all Reaches 11 Contractor shall not disturb mote active stream channel than can he stabilized by the and of the day. All stream banks and the buffer area within 25' of the active stream shall be stabilized at the end of each workday. Stockpiles shown are to be used while the existing stream is flowing- Stockpiles are prohibited Within 25' of the top of the flowing stream bank. A 24-hour pump -around maybe required if in -stream construction knot completed an by the and of the work day. 2) No material from the off-line Design stream channel excavation may be backfilled into the adjacent existing stream channef until the newly-coostructed Design stream section is completed, stabilized, and the stream flow has been cilverted Into it, not even if that section of old/ existing stream 15 being pumped. 3) Clearing and grubbing activities shall not extend more than 150 linear feet ahead of in -stream work. The Little Pine Creek II Stream & Wetland Restoration Project construction will follow the construction sequence protocol as described below, unless otherwise noted. Initial Site Preparation 1) Contact North Carolina "ONE CALL" Center (1-800-632-4949) before any excavation. 2) Contact NC Division of Energy, Mining, and Land Resources (OEMLR) at 336-776-980D before any work begins on the project and notify them of the start data, 3) Install temporary livestock exclusion fencing as outlined In the specifications. 4) Prepare stabilized construction entrances and staging areas as Indicated on the plans. 51 Mobilize equipment, materials, prepare staging, disposal, and material stockpile area(s) as shown on plans. 61 Walk site with Designer to Identify and flag transplants to he harvested for used throughout project. 71 Set up erosion control measures as outlined In the plans. Erosion and sediment control measures shall be installed by the Contractor to protect the Design stream channel from significant runoff prior to permanent stabilization. Silt fence should be installed where apprapriate atany designated sell harvest or disposal areas. Contractor is responsible for inspection and maintenance of erosion control measures through the duration oFconstruction. 8) Install safety fence along wetlands as detailed on the Erosion Control plan sheets. Safety fence shall be installed along the boundary of all wetlands adjacent to disturbance not permitted for Impact. 9) Install temporary stream crossings. Temporary stream crossings shall be culverts on Little Pine Creek and mudmat crossings on the tributaries. Mudmats shall be installed such that there are no gaps in the timbers. 10)Install and maintain an anslte rain gauge and log book to record the rainfall amounts and dates. Complete the self -inspection as required by NC DEMLR permit. Little Pine Creek Channel Construction Notes il)Constructlon shall generally begin at the upstream extent of the project (Little Pine Creek, Reach 1, Station 100+00) and progress downstream to Ste. 174+51, 12)As work progresses, remove and stockpile the top 31nahes of soil from the active grading area. Stockpiled topsail shall be kept separate far onsRe replacement prior to floodplain needing. 13)lnstall the pump around system priorto beginning excavation within the existing live channel bed. The pump around system needs to be employed only when work is being conducted within the active channel. Contractor shall stage his work to minimize the duration of pump around operations. 141Install Impervious dikes at upstream and downstream ends of pump around locations. The pump around operation shall be performed between these locations as described in plan detalls. 15)Remove all non-native and Invasive vegetation prior to beginning the channel construction. 16)Contractor should attempt to construct the channel offlroe, where feasible. If site conditions permit more than one offline section maybe constructed concurrently, however offline sections shall be tied online sequentially from downstream to upstream. 17)The Contractor shall not disturb more active stream channel than can be stabilized with seed, mulch, and matting by the end of the day. Excess cut material from above Glade Creek School Road may be stockpiled within the established stockpila area upstream of the road or hauled directly to the fill location downstream. 19)Construct the Design stream channel to the grade specified in the cross sections and profile. Transfer coarse material from abandoned channel riffles to new channel riffles. Rackfill abandoned channel sections with stockpiled soil. 19)install log and stone structures and in -bank hioenginearing such as brush mattress or brush toe after channel grading Is completed. 20)Seed (with appropriate seed mix) and straw mulch areas where the coir fiber matting is to be Installed. 21jinstall coir fiber matting. 22) When channel construction is completed remove the temporary stream crossing structures and Install the permanent ford crossing per the plans and specifications. 23)Prepare floodplain For seeding Ly applying stockpiled topsail to the flncdpla}n between bankfull elevation and the grading limits, ripping, and raking/ smoothing. Seed and mulch.

Background Information DMS requests to update the Little Pine Creek 11 Restoration Project from a 5-year, non-credit release monitoring term to a 7-year, credit release term to become better aligned with more recent project monitoring and credit release schedules. This project, a DMS design -bid -build project originally instituted in December 2007, has had several delays due to landowner issues, a temporary ban on trout waivers (2010), a construction contract termination and design reassignment (2013), conservation easement adjustment (2015), mitigation plan addendum (2016) and significant hurricane damage during construction (2018). The project was built according to the January 2016 mitigation plan addendum design (Wildlands Engineering), and now has a final, LSS-sealed as -built survey dated July 14, 2019; it is currently under advertisement for post -construction monitoring services (firm to be determined via bidding process).

Performance Standards Performance criteria from the October 24, 2016 USACE Public Notice guidance will be followed and are outlined as follows: Restored Stream Channels 1. All streams must maintain an Ordinary High -Water Mark (OHWM), per RGL 05-05. 2. Continuous surface flow must be documented each year for at least 30 consecutive days. 3. Bank height ratio (BHR) cannot exceed 1.2 for all measured cross sections on a given reach. 4. Entrenchment ratio (ER) must be above 2.2 for all measured riffle cross -sections on a given reach (for C and E streams). 5. BHR and ER should not change by more than 10% in any given year for all measured cross sections on a given reach. 6. Must document occurrence of at least 4 bankfull events in separate years during the monitoring period. Riparian Vegetation 1. Within planted portions of the site, a minimum of 320 stems per acre must be present at year 3; a minimum of 260 stems per acre must be present at year 5; and a minimum of 210 stems per acre must be present at year 7. 2. Trees must average 6 feet in height at year 5, and 8 feet in height at year 7 (mountain region). 3. Planted and volunteer stems are counted, provided they are included in the approved planting list for the site. 4. Any single species can only account for 50% of the required stems per monitoring Plot. 3. Monitoring Plan A MYO baseline report and as built record drawings will be provided to the NCIRT for review and comment prior to the initial 30% release for the site (see credit release section below). The baseline report will be performed by the firm awarded the monitoring contract and provided by NCDMS together along with the designer -sealed record drawings. The most recent DMS As -Built Baseline Monitoring Report Template will be used to document the baseline conditions. Annual monitoring data will be reported using the latest NCDMS Monitoring Report Template. All monitoring reports will include at least a brief narrative of site developments, a representative photo log, and a Current Condition Plan View (CCPV). Monitoring Year 1 will be calendar year 2020. The proposed locations of monitoring features are shown in the monitoring figure below as an Attachment. Annual monitoring reports will be completed for all seven years and provided to the NCIRT no later than April 1 of each monitoring year. Monitoring data collected on the site will include reference photos, plant survival analyses, hydrology, channel stability analyses, and visual assessments. Stream monitoring will include monitoring of the hydrologic and geomorphic functions of the project restoration reaches. Vegetation monitoring will evaluate the establishment of planted and volunteer vegetation across the site. A visual assessment of the entire project will be conducted on an annual basis. This data will be presented in the Current Condition Plan View (CCPV) with supporting NORTH CAROLINAD DWaNmM of&M-U, 4ua9N North Carolina Department of Environmental Quality I Division of Mitigation Services 217 W.

Problem areas of vegetation, in -stream structures, and channel migration will be noted and documented with photos. Monitored parameters, methods, schedule/frequency, and extent are summarized as follows: Paramet Method Schedule/ Number/ Extent Frequency Stream Morphology* MYO only All restored stream Stream Profile Longitudinal profile of the thalweg, water surface, (unless channels (2496 LF Little Pine bankfull, and top of bank otherwise Creek, 763 LF Tributaries) required) 9 cross sections on Years 0,1, 2, Little Pine Creek (5 Riffle /4 pool), Stream Dimension Cross sections 3, 5, and 7 4 cross sections on tributaries Channel Stability Visual Assessment Annually All restored stream channels CVS Level II Permanent vegetation plots, 0.02 acre in size 8 plots Vegetation establishment (minimum) Years 0,1, 2, and vigor Annual random 3, 5, and 7 vegetation plots, 0.02 acre in size 4 plots (minimum) Hvdroloev Stream Hydrology Continuous stage recorders (CSR) and crest gauges (CG); When possible overbank events will be corroborated with photographic evidence.

Proposed Credit Release Schedule The project will follow the release schedule specified in the October 2016 NCIRT guidance for ILF/NCDMS projects. The following conditions will apply to the credit release schedules: A. A reserve of 10% of a site's total stream credits will be released after four bankfull events have occurred, in separate years, provided the channel is stable and all other performance standards are met. In the event that less than four bankfull events occur during the monitoring period, release of these reserve credits is at the discretion of the NCIRT. B. After the second milestone, the credit releases are scheduled to occur on an annual basis, assuming that the annual monitoring report has been provided to the USACE in accordance with Section IV (General Monitoring Requirements) of this document, and that the monitoring report demonstrates that interim performance standards are being met and that no other concerns have been identified on -site during the visual monitoring. All credit releases require written approval from the USACE. C. The credits associated with the final credit release milestone will be released only upon a determination by the USACE, in consultation with the NCIRT, of functional success as defined in the Mitigation Plan.

This project recently got updated via a request from DMS to the IRT dated 9/9/2019, to update the monitoring period from 5 years to 7 years, outline updated monitoring requirements and performance standards, and introduce a formal credit release schedule. Project construction officially closed on 8/13/2019, subsequently had a monitoring contract awarded, and is currently undergoing baseline monitoring features set up. Mitigation success monitoring will be started in 2020 (MY01), and the MYO report should be made available in late January 2020. The following is a summary of the field review and items discussed during the meeting: • The group met at the wet crossing on project Tributary A, and briefly discussed the project status and recent history. It was noted that a monitoring firm had recently been awarded a contract and that the baseline monitoring feature installation would begin on 11/12/2019. Hard copies of the official designer as -built record drawings and a DMS proposed monitoring features map were distributed by DMS. • The group walked to the upstream end of the project (STA 100+00); the group then walked to the neighboring property upstream of the project to understand the nature of NORTH CAROUNA� �� Dm rb mf of FWY_ =n l Duelify North Carolina Department of Environmental Quality I Division of Mitigation Services 217 W. Jones Street 1 1652 Mail Service Center I Raleigh, North Carolina 27699-1652 919.707.8976 the offsite stream and how it might be influencing onsite project streams. The IRT noted that during a previous mitigation plan review visit there had been concern about the offsite stream cutting into the project area across the right floodplain, but stream hydrology currently appears to be flowing into the project area in a more favorable orientation, with a possible oxbow forming (offsite). The geolift/riffle structure from STA 100+00 TO 101+00 installed as a post -hurricane Florence (Sept. 2018) storm repair appeared to be performing well and moving sediment through the system while protecting the stream banks adequately thus far. • Walking downstream to the bridge crossing on Glade Creek School Road, the stream appeared to reflect the record drawings and no major concerns were noted on Little Pine Creek or Tributary A. The boundary is well marked, and flood flows were evident on the left floodplain from an overbank event approximately 10 days earlier. The floodplain sills and associated brush material appeared to be intact and performing well. • The group moved farther downstream across the roadway and bridge, where DIMS noted that a breakaway electrified cattle rope along a wet crossing adjacent to Glade Creek School Road had become entangled with a white pine branch and ripped loose (likely during the recent overbank event). DIMS indicated that the landowner is expected to fix the fence and that he had been contacted. • The group moved farther downstream towards STA 112+00 and the confluence of Tributary B with Little Pine Creek. All structures appeared to be intact and performing as installed. Tributary B was observed. • The group walked along the right floodplain of Little Pine Creek to the downstream limits of the project. In general, there were no major issues noted, and all structures were intact and performing well but DIMS and IRT agreed that floodplain woody vegetation did not seem very dense in areas, despite post -construction bare root planting at 605 stems/acre. Floodplain soils in some areas are gravel and cobble -dominated, where floodplain flows are moving sediments during overbank events. It was noted that vegetation density will be monitored closely upon receipt of the MYO baseline report and vegetation data, and supplemental planting will occur in the next dormant season if initial stem counts are poor. There were some concerns with the standing water in the vernal pool on the right floodplain near STA 113+50; while there had been a recent overbank event that likely filled the pool, ideally the vernal pools should not hold water for extended time periods. The IRT noted that planting of aquatic vegetation in the pools would improve these features in the event that they hold water longer than preferable. The other three vernal pools farther downstream were not holding water during the site visit. • DIMS asked the IRT to observe preservation Tributaries E and F (two small wetland 2B tributaries that merge together near the edge of Little Pine Creek), since the lower section of Tributary F has appeared to down cut somewhat since project design. Tributaries E and F (50 LF and 153 LF, respectively) were jurisdictionally confirmed during the design stage.

Jones Street 11652 Mail Service Center I Raleigh, North Carolina 27699-1652 919.707.8976 The IRT indicated that, despite some stable segments of Tributary F upstream of the head cut, that recent impacts and a head cut along Tributary F have affected stream performance on these reaches to the degree that they should not yield stream preservation credits. DMS indicated that the upcoming MYO baseline report would reflect no mitigation crediting for preservation on Tributaries E and F. • The group walked upstream through Wetland 2B and inspected the boundary marking along Wetland 2B. The entire length of preservation Tributary D (655 LF) was walked, flow was evident, and no major concerns were noted. DMS noted where the conservation easement contained the spring source and entire headwater feature on Tributary D. The group walked into the floodplain of Tributary C (restoration tributary totaling 578 LF). The adjacent enhancement wetland 2A appeared wet and the IRT seemed fine with the mapped location of the enhancement wetland gauge, although a more ideal location 10- 15 feet closer to Tributary C was agreed on; if changed, the installed gauge will reflect this updated location and will be noted in the baseline report. Tributary C was observed and no major concerns were noted, other than the thick herbaceous vegetation making visibility of bare root plantings difficult. • Other than the minor location adjustment of the wetland 2A gauge, there were no requested changes to quantities or locations of any monitoring features/devices (as communicated in the 9/9/2019 update memo and monitoring map provided by DMS to IRT). • The meeting concluded with DMS indicating their intention to post the MYO baseline report when it is finalized, and discuss the project accordingly at the next credit release meeting.
