We have revised the document in response to the review comments as outlined below. DMS MY6 Draft Report Comments: 1) References to stream "close out" should be removed or reworded. Please note that the stream portions of the project are not technically closed out yet, but are expected to close with the wetland portions in 2023; standard monitoring may cease since this is a 5-year stream project and the streams were performing well at the 2021 close out meeting. Like you state in the June 2021 meeting minutes, while standard stream monitoring may cease, any subsequent damage to the system that occurs prior to complete project closeout must be repaired. Response: Baker has revised all sections of the report that refer to the stream portion of the project as being closed -out and has also specifically noted that any damage must be repaired. 2) Please make final changes to the stream and wetland maps and associated credits as discussed in recent communications with DMS and IRT, regarding the minor stream credit shortfall resulting from the revised/updated wetland shapes (2.680 SMU). Please note the buffer method version run and summarize in the appendix the wetland and stream updates in a single table, while leaving Table 1 Project Mitigation Components unchanged; the project credits cannot be changed without a mitigation plan addendum, which is not necessary at this time; please revise the digitals accordingly and submit a complete set of final digitals. Response: Baker made the revisions as requested. 3) Odd pages of Table 9 are printing upsidedown in the hard copy. Response: Baker will correct this error in the final printed hardcopies. 4) Please optimize/compress the report PDF if possible. Response: Baker has compressed the report PDF as much as possible. As requested, two final hardcopies will be submitted to you along with a flash drive containing the report PDF along with all digital support files. Please do not hesitate to contact me should you have any questions regarding our response submittal.

MICHAEL BAKER ENGINEERING, INC. iii UT TO TOWN CREEKRESTORATION PROJECT- OPTION A (DMS PROJECTNO. 94648) YEAR 6MONITORING REPORT- 2021 1.0 EXECUTIVE SUMMARY Michael Baker Engineering, Inc., (Michael Baker) restored 5,554 linear feet (LF) and enhanced 791 LF (447 LF of Enhancement I and 344 LF of Enhancement II) of perennial and intermittent stream along an Unnamed Tributary (UT) to Town Creek and three additional unnamed tributaries. Also as part of this Project, Michael Baker restored and created 4.12 acres of riparian wetlands and enhanced 1.00 acre of riparian wetlands and constructed two wetland best management practices (BMPs) upstream of the mitigation areas. Though no mitigation credit is being sought for wetland enhancement, additional stream mitigation credit is being sought for the inclusion of the proposed stormwater BMPs and the extended riparian buffer width within the conservation easement. This report documents and presents the Year 6 monitoring data as required during the monitoring period. The primary goals of the Project were to improve aquatic habitat degradation by improving ecologic functions and reducing non -points source loads from agricultural run-off to the impaired areas as described in the Lower Yadkin — Pee Dee River Basin Restoration Priorities (RBRP) and as identified below: • Improve aquatic and terrestrial habitat through increasing dissolved oxygen concentrations, reduction in nutrient and sediment loading, improving substrate and in -stream cover, and reduction of in -stream water temperature; • Improve both aquatic and riparian aesthetics; • Create geomorphically stable conditions along UT to Town Creek and its tributari es through the Project area; • Prevent cattle from accessing the project area thereby protecting riparian and wetland vegetation and reducing excessive bank erosion; • Restore historical wetlands, create new wetlands, and enhance/preserve existing wetlands to improve terrestrial habitat and reduce sediment and nutrient loading to UT to Town Creek and the Little Long Creek Watershed. To accomplish these goals, the following objectives were identified: • Restore, enhance, create, and protect riparian wetlands and buffers to reduce nutrient and pollutant loading by particle settling, vegetation filtering and nutrient uptake; • Construct wetland BMPs on the upstream extent of Reaches 4 and 7 to improve water quality by capturing and retaining stormwater run-off from the adjacent cattle pastures to allow for the biological removal of nutrient pollutant loads and for sediment to settle out of the water column; • Restore existing incised, eroding, and channelized streams by creating stable channels with access to their geomorphic floodplains; • Improve in -stream habitat by providing a more diverse bedform with riffles and pools, creating deeper pools and areas of water re -aeration, and reducing bank erosion; • Control invasive species vegetation within the project reaches; • Establish native stream bank, riparian floodplain, and wetland vegetation, protected by a permanent conservation easement, to increase stormwater runoff filtering capacity, improve bank stability, shade the stream to decrease water temperature, and provide improved wildlife habitat quality. MICHAEL BAKER ENGINEERING, INC. UT TO TOWN CREEKRESTORATION PROJECT- OPTION A (DMS PROJECTNO. 94648) YEAR 6 MONITORING REPORT - 2021 UT to Town Creek Restoration Project — Option A (site) is located in Stanly County, approximately 1.7 miles west of the Town of New London, within cataloging unit 03040105 of the Yadkin Pee -Dee River Basin (see Figure 1). The site is located in a North Carolina Division of Mitigation Services (NCDMS) -Targeted Local Watershed (03040105060040). The Project involved stream restoration and enhancement, as well as wetland restoration, creation, and enhancement along UT to Town Creek and several of its tributaries, which had been impaired due to historical pasture conversion and cattle grazing. On June 3rd of 2021, the IRT held an on -site meeting to review early closeout for wetland credits and normal closeout for stream credits. As detailed in the meeting minutes found in Appendix F, it was ultimately decided that the wetland portion of the project will require continued monitoring through Year 7. As a result, while the stream portion of the project was performing well and no longer requires the standard monitoring protocols, it has not officially closed -out and any subsequent damage to the system must be repaired. Monitoring reports for Years 6 and 7 will therefore consist of vegetation assessments within the wetland areas, wetland gauge monitoring, and invasive species management. During Year 6 monitoring, vegetation conditions were performing at over 90% for planted acreage and close to 100% for invasive/encroachment area categories. As noted in Table 6b, an area (VPA6-1) of low herbaceous vegetation and poor growth rates has continued to persist from MY2. This area is located along Reach 2 between Vegetation Plot 14 and 13 and consists of approximately 0.06 acres. This area was supplemental planted with gallon plants, annual seed, perennial grass plugs and appropriate amount of lime in May 2020, but due to harsh temperatures and compacted clay soils this area is expected to have a high mortality. Michael Baker plans to continue seed and soil amendments to this area as noticeable improvements are being made. VPA data and photographic documentation collected during Year 6 monitoring are located in Appendix B. See Tables 6a through 6b for VPA data documentation. For Monitoring Year 6, no areas of invasive species were reported as none of the areas exceed the mapping threshold of 1,000 square feet (SF) and due to successful treatments conducted throughout 2021. Two treatment sessions were performed in April 2021 treating invasive species throughout the entire site. Species targeted consist of primarily Chinese privet (Ligustmm sinese) along with multi -flora rose (Rosa multiflora), princess tree (Paulownia tomentosa), and parrot feather (Myriophyllum aquaticum). The presence of these invasive species tend to occur predominantly in areas of the easement where mature woody vegetation is present and along the easement fence line with the exception of parrot feather found within the stream channel. These species will continue to be monitoring and treated as necessary for the remaining monitoring years. Based on data collected from the fourteen monitoring plots located within the credited wetland areas during Year 6 monitoring the density of total planted stems per plot ranges from 445 to 769 stems per acre with a tract mean of 604 stems per acre. Therefore, the Year 6 data demonstrate that the site has exceeded the minimums success criteria of 260 trees per acre by the end of Year 5 and is expected to meet in Year 7. The presence of volunteer woody vegetation was noted in vegetation plots; however, these species were not included in the average vegetation plot densities calculated for assessing the prof ect's interim success criteria. Vegetation stem counts are summarized in Tables 7 and 9 of Appendix C. Groundwater monitoring data collected during the growing season (March 27 through November 5) of Years 2, 3, 4, 5, and 6 documented that all ten groundwater monitoring wells exhibited soil saturation within 12 inches of the ground surface for the minimum success criteria hydroperiod of nine percent (9%) or 20 consecutive days during the growing season. Five of the ten groundwater wells' hydroperiods exceeded 50% with a high of 83.8%. The lowest hydroperiod was for well 8 at 12.6%. See Appendix E for a plot of wetland gauge data as it relates to monthly precipitation for Monitoring Year 6 (Figure 6). The Monitoring Year 6 wetland restoration success results are depicted in Table 12, and a summary of wetland attainment for all ten monitoring gauges is depicted in Table 12a. See Figure 2 (CCPV) in Appendix B for a depiction of wetland mitigation areas and corresponding gauge locations. Also, as explained in detail in the Wetland Boundary Adjustment memo found in Appendix G, a small area of additional wetland has been added as Creation (0.192 ac) as suggested by the IRT to compensate for the small MICHAEL BAKER ENGINEERING, INC. UT TO TOWN CREEKRESTORATION PROJECT- OPTION A (DMS PROJECTNO. 94648) YEAR 6 MONITORING REPORT - 2021 area of Restoration removed (0.047 ac) following the IRT site visit in June of 2019. This new area is but a small subset of the originally expanded Creation area submitted for addition in February 2021 as part of the MY5/Closeout report. Based on IRT comments on these areas during their field visit in June of 2021, much of these have been removed. The small area retained for Creation was the wettest looking portion and was readily accepted by the IRT in the field. It is also located very near the Restoration area being removed and was the area specifically pointed out by Mac Haupt (DEQ) during the June 2019 field visit as wetlands he suggested Michael Baker add. For these reasons, only this small, revised wetland area is being requested for addition as Creation (at a 3:1 ratio) to help ensure a smooth closeout of wetland credits next year. However, as a consequence of the revised Creation wetland boundary, the results from the USACE Stream Buffer Credit Calculator spreadsheet tool were affected as well. The additional credited wetland Creation area must be accounted for in the tool. As per DMS/IRT instruction, the same tool version (1/19/2018) that had been originally used for credit calculation was used here again for the revised analysis. The results indicate that by adding that small wetland Creation area, the project loses 2.68 SMUs as compared to the original analysis conducted in 2018 for the mitigation plan. For a more detailed explanation of this analysis, please see the Wetland Boundary Adjustment memo in Appendix G for the spreadsheet tool results and maps. The report e-submission provides the Excel spreadsheet and GIS shapefiles as well. The reduction of credits from the revised buffer tool was raised with the Corps by email along with a detailed explanation of all of the revisions that lead to the change. In their response on 12/13/21, the Corps stated that our current wetland boundary adjustment approach was acceptable and that the slight reduction in credits from the buffer tool would not result in reduced closeout stream credits (given the small number of credits involved). The email exchange is also included in the Wetland Boundary Adjustment memo in Appendix G. 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 NCDMS website. All raw data supporting the tables and figures in the appendices is available from NCDMS upon request. 2.0 METHODOLOGY The monitoring plan for the site includes criteria to evaluate the success of the stream, wetland, and vegetation components of the project. Complete stream and vegetation monitoring was successfully conducted for five years, while wetland monitoring will be conducted for seven years. A reduced monitoring protocol is now being conducted for the stream and vegetation portion of the project until final closeout approval with the wetlands in Year 7. Monitoring methods used will follow the NCDMS Monitoring Report Template, Version 1.2.1 — 12/01/09 and are based on the design approaches and overall project goals. To evaluate success criteria associated with a geomorphically stable channel, hydrologic connectivity, and aquatic habitat diversity, geomorphic monitoring methods will be conducted for project reaches that involve Restoration and Enhancement Level I mitigation. The success criteria for the proposed Enhancement Level II reaches/sections will follow the methods described in sections 2.1.3, 2.1.4, and 2.2, whereas, wetland restoration and creation mitigation will follow those outlined in sections 2.3. The specific locations of monitoring features, such as vegetation plots, permanent cross -sections, reference photograph stations, ground water gauges, flow gauges, and crest gauges, are shown on the CCPV sheets found in Figure 2 of Appendix B. Year 6 monitoring data were collected from September through November 2021. Vegetation data and plot photos were collected on September 14th of 2021. 2.1 Stream Monitoring As noted in the meeting minutes from the June 2021 IRT field visit, the stream portion of the project has performed well and a reduced monitoring protocol consisting of visual inspections has been allowed for the MICHAEL BAKER ENGINEERING, INC. UT TO TOWN CREEKRESTORATION PROJECT- OPTION A (DMS PROJECTNO. 94648) YEAR 6 MONITORING REPORT - 2021 final two monitoring years, though the stream credits are not yet closed out. As such, any impacts to stream function (bank scour, invasive species, etc.) will still be required to be addressed. 2.2 Vegetation Monitoring To determine if the criteria are achieved, vegetation -monitoring quadrants were installed and are monitored across the restoration site in accordance with the CVS-NCDMS Protocol for Recording Vegetation, Level 1, Version 4.2 (Lee 2008). The total number of quadrants was calculated using the CVS-NCEEP Entry Tool Database version 2.3.1 (CVS-NCEEP 2012) with twenty (20) plots established randomly within the planted riparian buffer areas. No monitoring quadrants were established within the undisturbed wooded areas of the prof ect area. The size of individual quadrants are 100 square meters for woody tree species. Level 1 CVS vegetation monitoring was conducted between spring, after leaf -out has occurred, and fall prior to leaf fall. Individual quadrant data provided during subsequent monitoring events includes species composition, density, survival, and stem height. Relative values were calculated, and importance values were determined. Individual seedlings were marked to ensure that they can be found in succeeding monitoring years. Mortality was determined from the difference between the previous year's living, planted seedlings and the current year's living, planted seedlings. 2.3 Wetland Monitoring Ten groundwater monitoring stations were installed in restored, created, and enhanced wetland areas similar to those from preconstruction monitoring to document hydrologic conditions at the Project site. The wetland gauges are depicted on the CCPV figures (Figure 2) found in Appendix B. Installation and monitoring of the groundwater stations have been conducted in accordance with the USACE standard methods outlined in the ERDC TN-WRAP-05-2 (USACE 2005). To determine if the rainfall is normal for the given year, rainfall amounts were tallied using data obtained from the Stanly County WETS Station (USDA 2021) and from the automated weather station at the North Stanly Middle School (NEWL) in New London, approximately 1.5 miles southeast of the project site on Old Salisbury Road. Data from the NEWL station was obtained from the CRONOS Database located on the State Climate Office of North Carolina's website (2021). Success criteria for wetland hydrology is met when each wetland site is saturated within 12 inches of the soil surface for 9 percent of the growing season as documented in the approved Mitigation Plan. To document the hydrologic conditions of the restored site, each groundwater monitoring station has been monitored for five years post -construction or until wetland success criteria are met. Visual inspection of proposed wetland areas was conducted to document any visual indicators that would be typical of jurisdictional wetlands. This could include, but is not limited to, vegetation types present, surface flow patterns, stained leaves, and ponded water. Wetland plants are documented along with other visual indicators noted above. Wetland restoration and creation areas that exhibit all three wetland indicators (the presence of hydric soils, wetland hydrology, and wetland vegetation) after construction and through the monitoring period validate wetland restoration and creation success. 2.4 BMP Monitoring The wetland BMPs located at the upstream extent of Reaches 4 and 7 will be visually monitored for vegetative survivability and permanent pool storage capacity during the remaining monitoring period. Maintenance measures will be performed as necessary. MICHAEL BAKER ENGINEERING, INC.

The purposes of this meeting were to: 1. Discuss credits to be released and to get ready for project closeout; and 2. Identify and discuss potential concerns/issues based on field observations. General recent weather conditions have been hot and dry for several weeks in the area apart from a few recent afternoon showers. The group met at the entrance of the path leading to the site off Old Salisbury Road (in the middle of the project) in Albemarle, NC. A general site overview and map orientation was provided and discussed. Reach 4 The group then started walking into the site towards the top of Reach 4 to discuss the intermittent flow and overall condition of the wetland BMP. Upon assessing Reach 4 it was noted that there was minimum vegetation growing in the stream bed and sediment is being flushed out of the system. Mac, Todd, and Steve discussed with Scott that it will be helpful to install either a flow gauge or flow camera to help document the flow of Reach 4 and 5, about % of the way up each reach. We then walked up the reach to look at the BMP. It was commented that the concrete level spreaders are no longer the preferred method for BMP outlets, but that it appears to be functioning well. There was a significant amount of clear, standing water present within the deep pool section of the BMP. No gullies or rills were observed flowing into the BMP, and established vegetation is present all around the BMP. Upon observation in this low-water condition the group did not feel the functioning of the BMP was threatened by excess sedimentation and no maintence was suggested. The group did express some concern that the BMP was fairly deep, and that it may be reducing the amount of water flowing into its downstream system. We then walked downstream to the confluence of Reaches 4 and 5 to look at the flow gauge and it the stream condition. There was no water present in the stream, but staining on the PVC pipe and streambed along with a general lack of streambed vegetation implies that water is routinely in the channel. Reach 6 The group congregated at the pipe crossing where Travis Wilson (WRC) had a concern with the installation of the pipe. In the as -built plans it was noted that the pipe was installed on top of bedrock; and therefore the pipe is perched above the downstream water surface. DMS, USACE, and DWR all agreed that there is not much that we can do about the situation now and that resetting the pipe would not be needed. It was also commented that for future sites that a bottomless pipe could be a good option, though the general consensus was that in this specific case it does not appear that would have helped as the native bedrock in this section appears to be naturally perched in this location. The group continued down the reach to the confluence of Reach 6 and 3. Reach 3 When looking at Reach 3 it was commented that the vegetation looked good, especially for the slate belt region. It was apparent that many of the trees were growing with good height for a 4-year project and the smaller trees were ones that were supplemental planted in 2018. A bare area located on the left bank at the bottom of Reach 3 was noted in the MY3 report shown as a vegetation problem area (VPA). We commented that we have reseeded and replanted it and will continue to monitor this area. Mac took a soil sample on the left flood plain in a wetland area upstream of the confluence with Reach 6 and down to —6 inches did not see the expected hydric soils. He commented that we will need to revisit the site and do a thorough inspection of our wetland boundaries prior to closeout, adjusting the exact, final boundaries to our field assessments. Mac pointed out that final boundaries may have shifted some and pointed out areas that looked wetter near where he took his soil boring. Todd then inspected nearby Well 5 and saw no issues with the installation of the well and measured 11 inches to water surface in the well. Mac did another soil sample near the well and saw very hydric soils throughout the sample. Paul stated that the well success criteria is 9% and all wells for this site have met that criteria for all monitoring years. We then walked upstream to the double culverts located at the break of Reach 2 and 3 where Todd and Mac commented that they did not like how wide the downstream section of channel was constructed and asked this be avoided in the future. However, we showed that both the construction and as -built plans indicated it was built as designed and the stream was stable. It was noted that this section of channel is all bedrock. Paul Wiesner pointed out that problem areas of invasive species (privet and parrot feather) were noted in the MY3 report, primarily along sections of the main channel. We replied that two treatment efforts have been made so far this year starting in March 2019 to address all invasive species throughout the site, and we plan to continue to monitor and treat these species for the life of the project. Reach 7 The group then headed to Reach 7 to inspect the intermittent channel and wetland BMP. Towards the middle of the reach water was flowing in the channel with good vegetation establishing along the banks and within the buffer. We then walked to the top of the reach to the BMP. Harry had commented on the MY3 report that he had observed turbid water and potential sedimentation following a rain event during his winter inspection, and asked how Michael Baker planned to monitor the BMP for any potential maintenance needs. The group inspected the BMP under the current, low water -level conditions and noted that the there is only a small amount of sediment (roughly 6" of a primarily silt/clay material) captured in the deeper pool portion of the BMP. The standing water that was present at the bottom of the pool was quite turbid. However, after observation in this low-water condition the group did not feel the functioning of the BMP was threatened by excess sedimentation and no maintence was suggested at this time. No gullies or rills were observed flowing into the BMP, and established vegetation is present all around the BMP. Scott explained that both of the project BMPs were designed to a depth in anticipation of some sedimentation for the period after construction before vegetation could establish when some amount of erosion can usually be expected. Scott also mentioned that we will keep an eye on the sedimentation/fill and confirm that ample storage room is maintained within both of the project BMP's. We can do that through visual inspections in the dry season when remaining storage capacity can be directly observed. The group also expressed some concern that the BMP may be reducing the amount of water flowing into its downstream system, though given the flowing water observed in the channel downstream this was not as much of a concern here. Paul brought up that it was noted on the MY3 report that a tree or two was down on Reach 1 and we confirmed that they have been cleaned up and that all fencing is in good condition. This concluded the walkover and below are a few notes that were discussed back at the vehicles before departure. - Credit release: Todd and Mac agreed to all credits being released for MY3 - A gauge or flow camera should be installed on Reach 4 and 5 (about % of the way up) - The wetland boundaries need to be re-evaluated to represent the actual boundaries in the field, particularly with regard to hydric soil formation - The pipe crossing on Reach 6 is sufficient - A photo point of each project culvert location will be added to the monitoring report This represents Michael Baker Engineering's best interpretation of the meeting discussions.

Recent weather conditions have been hot and dry throughout the spring and summer in this area. For your convenience, pleasefind included here figures from the most recent CCPV from MY5 along with the wetlands map from the wetland adjustment report. The group met at the crossing between Reaches 2 and 3 and began by walking down Reach 3, inspecting both the stream and the adjusted wetland area proposed in the MY5 monitoring report. The wetlands added to the credited area (all as Creation) in the report were closely evaluated by the IRT. The areas added adjacent to the existing Restoration areas (upstream of XS-11 roughly) were well received by the group. Those added below this point and adjacent to the existing Creation areas were considered more questionable. The existing Creation area located closer to the channel is noticeably wetter with some standing water observed and more herbaceous wetland species present. Tree vigor is clearly lower in this area, though there is no height requirement with this project. Plant densitywas also noticeably lower here than other portions of the project but is still well above the MY5 performance standard of 260 stems/acre (based on all veg plot data and transects conducted by Baker). Hydric soil was found within both the original and newly added Creation areas, though Todd correctly noted that this was an area where a floodplain was cut so the hydric soils may not be indicative of a high water table (this is why this area was originally classified as Creation and not Restoration). Todd investigated a couple of riffle sections in Reach 3 and noted good channel bed features in both but found a pocket of parrot feather in one. Baker has treated this twice a year for several years and have reduced the parrot feather present to a remarkable degree. Harrynoted that the system had been choked with it before we began treatment. We then began walking up Reach 6 for a relatively short distance before turning back after a brief inspection that met to everyone's satisfaction. The groupthen hiked outside the easement up to Reach 7, hopped the fence to inspect the middle of Reach 7 (which was flowing and quickly deemed to be acceptable) then moved downstream to its confluence with Reach 2. We then walked downstream back to the vehicles at the crossing, moving between the left and right floodplains. The stream was noted to be in good condition and accepted by the group. Some of the wetlands along the left floodplain had visual similarities tothose at the lower section of Reach 3, though Scott emphatically noted that this area appears much wetterthroughout the winter and into spring, with significant standing water present for extended periods. The trees are notably shorter here than in other areas (again, no height requirement on this project) but their density is good. Herbaceous vegetation is present here but not as thick as most of the rest of the site. Other wetland areas along the right floodplain looked very good to the group, though notably they are usually so wet as to be nearly impassable with deep muddy conditions. The very dry spring clearly resulted in all wetland areas visuallyappearing much different than is normal. Scott noted that this project is located within the Slate Belt, which under normal conditions will dry up quickly during the spring and summer. Thus, many of the wetlands did not 'present themselves' visually as well as they do normally. However, the combined acreage of the questioned wetland areas makeup only a small portion of the overall wetlands and a very small portion of the project as a whole. All of the groundwater wells met their performance standards, with hydrology percentages averaging 30-50%for the past three years (for MY5 virtually 100%!), far exceeding the set success criteria of 12%. The group then stopped near the crossing to discuss the project evaluation and IRTconclusions and then left to meet at the Town Creek project located close by. Summary Points: • The remaining Stream Credits are approved for closeout by the I RT, though DMS will still withhold 10% of the total stream credits until final project closeout. All stream monitoring may cease, though any subsequent damagetothe systemthat occurs until complete project closeout must be repaired. The remaining Wetland Credits are not releasedfor early closeout and should be monitored for the remaining two years (MY6 and MY7). If the Creation wetlands of concern (those areas added adjacent to the original Creation areas roughly below XS-11) are used for credit in the final revised wetland adjustment, then the IRTwill require the installation of a groundwater well to demonstrate hydrology. However, Baker intends to remove all of those questionable Creation areas (cited above) that had been added in the wetland adjustment report to facilitate a smoother closeout. Baker will submit a final, revised wetland credited area adjustment report with the MY6 monitoring report for I RT review. • The MY6 report will also include a revised calculation of additional stream credits for wider buffers using the same January2018 methodology that was previously used to determine the credits (the previous calculation has been subsequently affected by the modification of credited wetland boundaries). • Treatment of invasive species, part icularlyparrot feather, will continue until complete project closeout. • While MY6 monitoring typically focuses on a more visual inspection (with the reduced monitoring requirements found in MY4and MY6) Bakerwill still monitor all wetlands in full and will run vegetation transects within all newly added wetland credit areas. • Vegetation data collected for MY7 can focus on the veg plots located within and adjacent to the wetland areas. • This represents Baker's best interpretation of the meeting discussions. If anyone should find any information contained in these meeting notes to be in error and/or incomplete based on individual comments or conversations, please notify me with corrections/additions as soon as possible.

The UT to Town Creek Restoration Project originally proposed to Restore a total of 2.56 acres of wetlands and Create an additional 1.56 acres of wetlands within the floodplains along both sides of Reaches 1, 2, and 3. The groundwaterwell monitoring conducted over the previous five years has demonstrated that all the wetlands have clearly met the hydrology success criteria of 9% as stated in the mitigation plan (often by a substantial margin —the lowest performing well in MY5 had a hydroperiod of 35%). However, during an IRTfield visit during the monitoring phase on 6/11/19 a few soil borings dug in the generalvicinity of groundwaterwell #4appeared to be more marginalto upland in appearance. The borings were dug in this location as the area appearedto be less 'wet' overall thanthe rest of the surrounding wetland area and had dense/gravellysoil. The IRT suggested conducting a closer review of the wetlands prior to closeout to adjust the boundary as needed. It was suggested that while some of the area of concern seemed likely to be removed as credited wetland, there certainly appeared to be plenty of wet areas adjacent to these potentially removed areas. Figure 1 shows the original wetland boundaries for the southern portion of project around the area in question. The IRT encouraged Baker to look for and add any new wetland areas to makeup for any upland area that required removal. As such, Baker conducted a thorough field and GIS evaluation of the area and modified the wetland boundary to remove the questionable area (0.047 ac) and add new wetland area (as Creation) as detailed in the original boundary adjustment memo dated 1/15/21. However, during the IRTsitevisit as part of project closeout activities on 6/3/21, a portion of the newly added areas of Wetland Creation at the southern extent (below XS-11) were questioned by the IRT. These areas did not appear as 'wet' as the other areas added and the IRT requested that if they were ultimately to be included as credited wetland area, theywould require additional groundwater monitoring. The meeting minutes from that sitevisit were approved on 7/7/21 and provide a more detailed summaryof the discussion that day. They can be found in the Appendix of the MY6 report. Given the feedback from that IRTwalkover, Baker electedto remove all of the Wetland Creation area that was considered questionable, as well as much of the rest of the newly added Wetland Creation area, excepting a small portion of the very wet area around XS-10 and Veg Plot 11. This area is actually quite near the Restored wetlands being removed from crediting, and was the original area specifically pointed out by Mac Haupt (of DEQ) during the first IRT walkover in 2019 as being what he would recommend Baker add as recompense for any lost wetlands. It is also by far the wettest portion of the added Wetland Creation area, has abundant tall vegetation, and was readily accepted by the I RT during the walkover in June of 2021. At an area of 0.192 acres, it adequately covers the credits lost from the removal of the nearby Restored wetlands. Figure 2 shows this final area as well as all of the previously added Creation areas (which have subsequently been removedfrom consideration) and their previous soil borings. This very limited area of Wetland Creation (only a small subset of the original) is being submitted for the purpose of facilitating a smoother closeout after MY7. Photos of this area were collected during the previous field investigation in January 2021 and have been included again here, while more recent photos were taken of this area in November 2021 and are also included here. Additionally, as per IRT request during the field visit in June 2021, the revised Creation area addition was assessed forvegetationthrough the collection of 2 temporary vegetation transects, each approximately the size of a standard monitoring veg plot. As noted above and as documented in the photolog, the area as a whole has quite tall, abundant vegetation consisting of sycamore, persimmon, blackgum, green ash, swamp chestnut oak, willow oak, box elder, tulip poplar, buttonbush, silky dogwood, and black willow, with thick herbaceous vegetation dominated by tearthumb, soft rush, and woolgrass (amongst other rushes and sedges). These species are overwhelmingly rated as wet for their facultative indicator status for the Eastern Mountains and Piedmont region. The first vegetation transect identified 14 stems (for a density of 566 stems/ac), all but 3 of which were well over 6 ft tall. The second vegetation transect identified 15 stems (for a density of 607 stems/ac), of which 8 were well over 6 ft tall (and the remainder averaging about 4 ft tall). Figure 3 shows the approximate location of the transects within the revised Creation area. As previously noted in the original wetland adjustment memo, the Creation Wetland area being added will be credited at a 3:1 ratio, while the Restored Wetland area being removed was credited at a 1:1 ratio. The newly revised wetlands on the project total 2.513 acres for the Restoration component and 1.752 acres for the Creation component, for a total of 3.097 Riparian Wetland Credits. Baker is contracted for 3.0 wetlands credits. The revised wetland credits are shown below in Table 1: Table I. Adjusted Wetland Areas Area (ac) Ratio Credits Original Wetlands Riparian, Restoration 2.560 1:1 2.560 Riparian, Creation 1.560 3:1 0.520 Total Credits 3.080 Adjusted Wetlands Riparian, Restoration 2.513 1:1 2.513 Riparian, Creation 1.752 3:1 0.584 Total Credits 3.097 Riparian Wetland Credit Difference +0.017 This minor adjustment of the credited wetland boundaries also affected the results of the buffer spreadsheet tool used in the mitigation plan to determine additional stream credits from the implementation of wider riparian buffers. As per I RT request, the same 2018 version of the buffer tool originally used for the mitigation plan was used again to re-evaluate the stream credit calculation, only using the new wetland boundaries. As shown below in Table 2, the analysis revealed that the addition of the Creation area results in the loss of 2.68 stream credits as compared to the original analysis (from 265.32 to 262.64 credits). Tablet. Adjusted Stream Credits from Buffer Tool Original Stream Credits: Additional Credits from Buffer Tool* 265.320 Revised Stream Credits: Adjusted Credits from Buffer Tool (using revised wetla nd boundaries) 262.640 Difference in Credits 2.680 *These additional stream credits were rounded down to 265.000 when presented in the Credit Table 1 for the mitigation plan. A printout of the buffer tool summary page is included with this memo, and the spreadsheet tool and GIS shapefiles used are included as part of the e-submission files for the project MY6 report. As per DMS request, the Corps was consulted on 12/9/21 about this loss of stream credits to see if they felt it would impact the final project closeout numbers. Given the small credits involved and the fairly complicated nature of any of the proposed remedies (further altering the wetland boundaries to avoid certain buffer widths and/or using the new buffer tool) the Corps responded that our current approach was acceptable and that the slight reduction in stream credits from the buffer tool would not result in reduced closeout stream credits. Thus, the project can closeout as proposed. See attached email exchange for more details of this discussion. Its hould also be noted that there are anadditiona1 —1 acre of existing jurisdictionaI wetlands on the project that were enhanced for no credit on the project. These wetlands had cattle excluded, were planted, and aImost certainly experienced improved hydrology along with the adjacent restored wetlands. Most sincerely, Scott King, LSS, PWS Scott.

The wetland adjustment plan is acceptable to the IRT. Given that 2.680 credits is a small amount, and removing sections of wetlands and applying the new buffer tool complicates the issue, no further mitigation plan or contract adjustments will be needed. We'll plan on closing the site out as originally proposed.

If the IRT has any concerns, we'd like to have them sorted them out now rather than next year at closeout. We had an IRT field visit back in June of this year and I see from our meeting summary memo that you weren't actually in attendance that day. That's a shame. I was specifically asked to coordinate with you as I understand Todd has a temporary re -assignment coming up(?). However, we can include him in on the conversation if you think that's prudent and he wouldn't be bothered by that. I have also included Erin Davis of DEQ as she was there and part of the discussion as well. Basically, we have a situation where at a previous field visit back in 2019, Mac Haupt discovered a small pocket (0.047 ac) within our wetland restoration area that hadn't developed hydric soils and suggested we pull it out and add -in an adjacent area that was very wet. As per DMS suggestion, we ended up doing a larger scale re -delineation of a much broader area, adding significantly more proposed wetlands (as Creation at 3:1) to the project. At the recent field visit in June of this year, much of this wetland area was accepted except for a narrow section at the southern end. It does not visually look as wet as the upper portions we added. As such, we were asked to either remove this portion from our new proposed wetland area or install a groundwater well or two and document the area much more thoroughly. As we didn't need all the newly added wetland area anyway to compensate for the lost area, and didn't want to have install a well for the next two years, we decided to remove this controversial area entirely and simply propose keeping only the minimum area needed to compensate for the lost wetlands. We ended up dropping almost all of the originally proposed wetland addition and have only kept the wettest area that had been readily accepted in the field that day (about 0.20 ac). The area we kept is also the exact location that Mac suggested we add back in 2019! 1 had hoped by making these changes the wetlands would be more readily acceptable by the IRT and easier on Baker as the area is small and simpler to document (veg and soils) and wouldn't require any more groundwater wells, etc (please see the attached Figure). However, by using this small area of added wetland as compensation, it altered the results of the buffer tool analysis which we had used to obtain extra stream credits for the project. We had been told to re -run the analysis using the older version of the buffer tool (the same one we had used originally) just with the new wetland area. It has resulted in the loss of 2.680 SMU, putting us below our official Table 1 credit numbers. So, with all that background in place, here are the questions DMS wanted me to run by you: -As we are now technically down 2.680 SMU from our official credit table from the loss of buffer tool credits, DMS is concerned that there will need for mit plan or contract adjustments and Baker is concerned about loss of credits for payment. DMS suggested that if the number is really that small that the IRT might just let it slide and closeout with full credits intact, meaning no further mit plan or contract adjustments needed. Is that possible? If so, we will keep the wetland area as we now have it and move forward. However, if that's not acceptable I would offer an easy solution to make things simpler all around. I can adjust the proposed wetland boundary to kick out a small triangle of about 1,400 ft2 in size that is affecting the buffer tool credit results (see the attached figure). We would still be able to compensate for the wetland loss but not lose any SMU. I had thought about that a while back but felt uncomfortable obviously skewing a boundary for that purpose. It felt like I was gerrymandering the boundary for a self-centered intent! However, with the IRT's permission, I could do that and it would solve that issue. But if being off by 2.680 SMU isn't a big deal to you then we can just go with what we have. -DMS had suggested that IF the loss of 2.680 SMU must be addressed and IF my proposed wetland boundary adjustment isn't acceptable (where I cut out a small triangle) then maybe we could be allowed to us the newer buffer tool, which I am told allows for more credit around stream terminals and so would easily allow for more stream credits. Honestly, I would prefer not to have get ahold of the new tool and start from scratch though. -And finally, is the overall wetland adjustment plan acceptable to the IRT? Any questions or concerns? I had previously contacted Todd back in July about my plan and he was agreeable to it (see attached email) but that was before I had anything finalized to show him. It was just theoretical. I have also attached the meeting minutes from the June 2021 IRT field visit as well. I totally understand this is A LOT to throw at you! I would love to discuss this further over the phone (or Teams or Zoom) if you like but I wanted both of you to have the full discussion and explanation in text first. And again, we can certainly get up with Todd too if you feel that's needed. Erin, I'm glad to have you as part of the conversation as well as you were there in June 2021. If either of you have any questions, please give me a call on my cell 919-219-6339. Thank you very much!
