HomeMy WebLinkAboutWLS CAT01 Starker_Final Mitigation PlanAugust 20, 2021 US Army Corps of Engineers Regulatory Division, Wilmington District Attn: Kim Browning 3331 Heritage Trade Drive, Suite 105 Wake Forest, NC 27587 RE: WLS Responses to NCIRT Review Comments Regarding the WLS Catawba 01 Umbrella Mitigation Bank (UMBI) Final Mitigation Plan Approval for the Starker Mitigation Project, USACE AID# SAW-2020-01540, Catawba River Basin, Cataloging Unit 03050101, Catawba County, NC Dear Ms. Browning: Water & Land Solutions, LLC (WLS) is pleased to provide our written responses to the North Carolina Interagency Review Team (NCIRT) review comments dated June 16, 2021 regarding the Draft Mitigation Plan for the Starker Mitigation Project. We are providing our written responses to the NCIRT's review comments below, which includes editing and updating the Final Mitigation Plan and associated deliverables accordingly. Each of the NCIRT review comments is copied below in bold text, followed by the appropriate response from WLS in regular text: USACE Comments (Kim Browning): L. UMBI: The correct agency representatives are a. Corps: Kim Browning, Wilmington District Mitigation Office, 3331 Heritage Trade Drive, Suite 105, Wake Forest, NC 27587 b. USFWS: Replace Claire Ellwanger with Holland Youngman C. NMFS: Replace Ken Riley with Twyla Cheatwood Response: These agency representatives have been updated in the UMBI. 5100: During the IRT site visit rehabilitation was discussed for Wetland A, with wetland enhancement inside the wood line. I would welcome the inclusion of this area in the mitigation plan for credit, particularly since Section 6 refers to wetland enhancement as being one of the critical benefits of stream restoration, provided a wetland gauge be installed prior to construction to document existing conditions and demonstrate functional uplift. Response: At this time WLS will not be requesting any wetland credit for the project. It was determined that Wetland A did not provide enough credit to make it feasible to add to the bank. WA is limited in size and uplift. Language has been added to section 6 making it clear that no credit is being sought for WA. General: I appreciate the level of detail and site -specific information provided. Response: Thank you. 4. Section 3.6.2: Please discuss the survey results for the dwarf -flowered heartleaf. Response: A survey for dwarf -flowered heartleaf was conducted on April 15, 2021, with no individuals found. The results are now included in Section 3.6.2 as well as the letter from US Fish and Wildlife Service which is included in appendix G. S. Section 4 and Table 7 references the stream functions pyramid and function -based goals as a way to measure functional uplift. Physiochemical and biological functions are benefits that are presumed and will not be measured by monitoring. Unless you intend to demonstrate actual uplift in biology and water quality, I recommend that these sections be reworded to state that uplift in these areas is implied. Response: Section 4.1.1 has been updated as well as Table 7. 6. Table 7: The landscape connectivity benefits related to biology are listed as "...the restored stream bed will allow animals to have easier access to a drinking water source." It's not appropriate for livestock to use the mitigation site streams as a source of water. It would be more appropriate to discuss aquatic species in this section. Response: This section has been updated and now discusses the benefits of aquatic and terrestrial species migration. Livestock will not have access to any part of the restored channels. 7. Table 8: Why are the proposed credits approximately 300 LF less than the existing length? Is this to account for stream crossings? The areas that are not credited but are park of this project should be listed as non -credited LF in this table. Response: The non -credited length was not included in the proposed credits. The non -credited linear footage is now included as a separate column in this table. 8. Sections 6.3 and 9.1.3: Is a rain gauge proposed to be installed on site to demonstrate normal rainfall conditions? If so, please indicate its location on Figure 10. Additionally, obtaining precipitation data from the Oxford RS is acceptable, but should that data not be available, we feel that the Hickory Airport Station that is 12.5 miles away is too far to accurately represent site conditions. Response: An onsite rain gage will be added on the project site to collect rainfall data. If there is a malfunction or data gap in the onsite data, the Oxford RS data will be used. The Hickory Airport station has been removed. 9. Section 6.3.1: Development within the watershed is a major consideration for this project and it's understood that increases to runoff patterns were accounted for when considering higher/steeper discharge curves and additional grade control structures. Were allowances for increased floodplain width and storage considered.100-150 ft buffers would be beneficial on this site. Response: The design incorporates adequate bench and floodplain widths to reduce velocities and shear stresses on the channel, both pre- and post -development. The buffer widths provided will be adequate for protecting the stability of the channel and were negotiated with the landowner. Buffer widths of at least 50 feet are provided but will exceed 50 feet, up to 70 feet, in many locations. These proposed buffer widths satisfy current regulatory guidance. 10. Section 6.4.1: Please include the location of the reference sites used. Additionally, add a figure that shows the location of the reference sites in relation to the project site. Response: The reference reach locations have been added to Section 6.4.1. Figure 1a was created to show the reference reach locations in relation to the project site. 11. Section 6.5: Please show these water quality treatment areas on Figures 9 & 10 and verify that they will not be placed in jurisdictional waters. Response: The water quality features have been added to Figures 9 & 10. These water quality features are not located in jurisdictional waters. 12. Table 16 and Design Sheet 3A: The Note indicates that species may change due to refinement or availability. Please notify the IRT if species are substituted, and red -line in the As -Built. Response: The note has been edited to indicate WLS will provide a red -line of the plating list in the as -built report. 13. Section 6.6: Since both Piedmont/Low Mountain Alluvial Forest and Mixed-Mesic Hardwood Forest target communities are proposed, these areas should be differentiated on Design sheets 28-31. It's also recommended to include a figure that shows the different planting zones. Response: The design sheets 28-31 have been updated and figure 11 has been added to the GIS figures to show the planting zones within the conservation easement. The planting areas shown are approximate and field conditions at the time of planting will dictate final planting zones. 14. Section 6.6.1: Vegetation planting must be conducted between November 15 and March 15. Response: WLS proposes that the planting be completed by the start of the growing season in Catawba County, March 30th (per WETS data). The planting date has been updated in section 6.6.1. 15. Page 39: Japanese stiltgrass should be added to this section. Response: Japanese stilt grass has been added to the invasive species section. WLS is not proposing stiltgrass treatment unless it threatens success of the planted trees. 16. Section 6.7.4: I appreciate the detail in this section. Under Land Use Development, please discuss the potential for future utility/sewer/greenway installation. The IRT is approached numerous times a year with encroachment requests and it would be beneficial to anticipate these concerns now. Response: Expanded discussion about future land use development has been added to Section 6.7.4. 17. Table 18, page 42: Livestock exclusion fencing is listed as a routine maintenance component; however, it's unclear on the figures and design sheets where fencing will be installed/is existing. Response: Livestock fencing will only be installed if the landowner keeps cattle on the property. Figure 10 now shows where fencing would potentially be installed. Fencing will be installed outside the conservation easement and will ultimately be the responsibility of the landowner to abide by the easement restrictions. 18. Page 43, Jurisdictional Stream Flow: Please note that the 30-days of consecutive flow should be viewed as a minimum threshold and not a goal. Streams that are currently listed as perennial are expected to have nearly constant flow all year. Response: WLS understands that 30 days of consecutive flow is the minimal number of days for an intermittent stream and will use gauges to monitor the entire growing season. 19. Page 43, Photo Documentation: Please include a statement regarding stability of crossings. Response: A statement about crossing stability by photo documentation has been added to Section 8.1. 20. Section 9.1: This section discusses Enhancement Level II. Please confirm that all reaches will involve a restoration approach. Response: This statement was outdated language from the prospectus and has been removed. All stream reaches in this project are proposed as restoration. 21. Section 9.2: It's unclear which areas of vegetation are considered preservation areas. a. Volunteer species on the approved planting list may be counted towards success after being present for two years. Response: Section 9.2 has been updated to state that volunteer species on the approved planting list may be counted towards success criteria after surviving two years. Figure 11 had been added to show the planting and preservation zones inside the conservation easement. 22. Section 10 and Appendix D: Please include the Long -Term Endowment calculation spreadsheet which shows how the amount of $61,297 was calculated (annual monitoring, signage replacement, travel, legal fees, cap rate, etc.). Response: The endowment calculation spreadsheet has been added to Appendix D. 23. Section 12, Financial Assurances: a. Performance and construction bonds are preferable to casualty insurance. Some concerns to consider with the use of casualty insurance include: The assurances need to be structured so that the timeframes in the effective coverage periods allow the IRT time to conduct reviews of the as -built and monitoring reports. Ideally, coverage for the different periods should only terminate once we have provided approval of the as -built or monitoring reports. Related to this, planting completion poses a potential issue. The timeframes included in the insurance policy that only cover construction through, for example, April 1st would obviously be insufficient since the IRT would never approve as -built until after the site work is complete (including planting). Response: WLS has utilized both performance bonds and casualty insurance on projects and prefers casualty insurance because of the longer and seamless coverage. WLS notes the concerns raised, but can address those concerns with the specific insurance policy. The casualty insurance will be structured to allow effective coverage periods that take into account review times for as -built and monitoring reports. Also, a draft policy will be sent to you for review before execution. Though the dates become more concrete once the policy is closer to being finalized, an example schedule for Starker would be: Construction: 10/15/21 to 6/15/23 MY1: 6/15/23 to 6/15/24 MY2: 6/15/24 to 6/15/25 MY3: 6/15/25 to 6/15/26 MY4: 6/15/26 to 6/15/27 MY5: 6/15/27 to 6/15/28 MY6: 6/15/28 to 6/15/29 MY7: 6/15/29 to 6/15/30 This schedule essentially has an extra year of monitoring coverage because MY1 would be in 2023, however the review of the report could go into early 2024. Also, coverage terminates only after the USACE as -built approval is sent to the insurance company. Coverage can be extended if needed, but this schedule fully accounts for construction and report review. b. The financial assurance section does include a cost breakdown and a provision for contingency/remedial action of $104,000, but this amounts to only 8% of the cost of construction, which seems inadequate. This amount also diminishes across the life of monitoring, so there is even less contingency funding available toward the end of the project. Response: A review of recent mitigation plans' financial assurances (EPR, RES, Wildlands) that are similar in size to Starker showed a range of $0 for contingency, 5.3%, and 8%. WLS proposes to keep the contingency at 8% of the construction costs, which are conservatively priced. The contingency and monitoring costs should decrease across the life of the project because the monitoring costs and need for maintenance/contingency decrease. WLS has revised the contingency to keep the $104,000 for MY1-MY3, which are the most likely years for maintenance. Then the policy would decrease in MY4 for the contingency. This will be addressed during the review of the draft casualty insurance policy, but below is what the coverage would look like: MY1: 6/15/23 to 6/15/24 $304,000 MY2: 6/15/24 to 6/15/25 $275,429 MY3: 6/15/25 to 6/15/26 $246,858 MY4: 6/15/26 to 6/15/27 $197,487 MY5: 6/15/27 to 6/15/28 $148,115 MY6: 6/15/28 to 6/15/29 $98,744 MY7: 6/15/29 to 6/15/30 $49,373 24. Correspondence from USFWS and NCWRC is attached for reference. USACE Comments (Casey Haywood): 1. Pg. 1 Intro: Please include site location and directions in the introduction. Response: The site location and directions are in Section 2.1. 2. Pg. 19 3.6.3 Conditions Affecting Hydrology- It would be helpful discuss the size and type of culverts in this section. Response: Culverts were changed to corrugated plastic pipe and the text in Section 3.6.3 was updated. 3. Pg. 23 Table 8 Proposed Stream Mitigation Credits: Recommend indicating P1/P2 restoration for project reaches. Also recommend identifying P1/P2 reaches on the Proposed Mitigation Map, Figure 9. Response: Table 8 has been updated and the reaches on figure 9 have been updated to show P1/P2 restoration approaches. 4. Pg. 28 Section 6.2.1 Stream Design Reach Summary a. S100- in section 3.6.3 Conditions Affecting Hydrology: S100 has one crossing being replaced and one crossing was being added as a potential future crossing. There are no discussion/details given for the culvert being replaced on this reach. Please provide further detail (size/type). Response: Section 100 (North of I-40, below the crossing) gives detail of the culvert being replaced. The existing farm crossing culvert at station 21+94.21 will be replaced with a 48-inch corrugated pipe. There is a second break in the conservation easement at station 37, this easement break is for a potential future crossing. No crossing will be constructed in this location at this time. b. It seems that many of the culverts being installed are smooth -wall HDPE. Please note that HDPE is the least preferred of all hydraulic structure materials because the smooth walls do not provide any roughness and do not hold substrate material. Response: The proposed culverts were switched to corrugated plastic pipe. 5. Pg. 38 The narrative mentions both Piedmont/Low Mountain Alluvial Forest on narrow stream floodplains and Mixed-Mesic Hardwood Forest (Piedmont Subtype) on adjacent side slopes. a. IRT encourages separating planting zones for wetlands, riparian areas, uplands, and streamside assemblages. Recommend adding a figure/map that identifies the planting zones. Response: Design sheets 28-31 have been updated to show separate planting zones and Figure 11 has been added to the GIS figures to show the planting zones within the conservation easement. Planting zones are approximate and final planting zones will be determined post -construction based on site conditions. b. Recommend adding wetland indicator status to the planting list on Table 16 and on design sheet 3A. Response: The wetland indicator status has been added to Table 16.On page 3J of the plan set you will find the same table. 6. Pg. 38 Section 6.6.1 Planting Materials and Methods: a. Please note that vegetation planting/replanting must be conducted between November 15 and March 15 in order to be counted toward success for the subsequent growing season. Response: WLS proposed that the planting be completed by the start of the growing season in Catawba County, March 301h (per WETS data). The planting date has been updated in Section 6.6.1. b. Please include discussion in the text how you plan to treat/manage the existing fescue. Response: In areas of undisturbed pasture WLS will assess fescue treatment options prior to planting. This has been updated in Section 6.6.1 under the invasive species section. c. During the September 30, 2020 site visit, IRT noted many black walnut species- Please include discussion in the narrative that existing black walnut may be removed as needed. It may also be helpful to add this to Table 18. Routine Maintenance Components. Response: During construction black walnut species will be removed as much as possible. Black walnut will be monitored post construction and treated if threating the success of planted vegetation. Language has been added to Section 6.6.1. 7. Pg. 42-43 Section 8.1 Stream Performance standards a. Please note that ER must be no less than 1.4 at any measured riffle cross-section on B- type reaches and no less than 2.2 on C-type reaches where ER is altered to reference condition through design and construction. Response: WLS notes these conditions and the proposed design parameter can be found in Table 10. b. Please add to the performance standards that BHR and ER at any measured riffle cross- section should not change by more than 10% from baseline conditions during any monitoring interval. Response: Section 8.1 has been updated with this language. 8. Pg. 46 Section 9.2 Vegetation Monitoring: What will the total planted acreage be for the site? Response: The total planted acreage for the site will be approximately 27.7 acres. Final planting zones will be determined based on as -built conditions. 9. Figure 8 and Table 9 stream lengths and credits do not match. Please update for consistency. Response: The table has been removed from Figure 8. 10. Figure 10 Proposed Monitoring Map: Please mark location of photo points to include crossings and culverts. Recommend adding a footnote to the figure if cross -sections are being used as fixed photo points. Response: Photo points have been added to Figure 10. 11. Appreciate flow gauges on 5101,102, & 103 in the upper third of the reach. Response: Thank you. 12. Appreciate that veg plot locations capture the various soil types and encompass portions of the existing wetlands. Response: Thank you. 13. Recommend adding some photos in the narrative. Response: Thank you for the suggestion and we will add more photos into the narrative of our future mitigation plans. A photo log can be found in Appendix H. 14. Please verify if the wetland groundwater gauge recommended on S100 during the September 30, 2020 site visit was installed. Even though wetland credit is not being pursued it is important to document existing conditions to demonstrate functional lift and ensure that there is no net loss of wetlands as a result of restoration. Response: Since WLS is no longer proposing wetland credit for the Starker site and therefore a wetland gauge was not installed after the IRT site visit. WLS will add a wetland gauge now to capture winter 2021 and spring 2022 data to ensure that there is no net loss of wetlands as a result of the stream restoration project. WRC Comments (Travis Wilson): 1. The culverts are currently designed as smooth wall HDPE. CMP or RCP should be used for pipe culverts. HDPE smooth wall pipes do not allow for any roughness and will not retain substrate in the structure. Additionally, due to the smooth wall and common algae accumulation these structures are not suitable for reptile and amphibian passage, which is a concern with the potential future development mentioned in the mitigation plan. Response: All proposed culverts were switched to corrugated plastic pipe. 2. "Future Crossing" located at approximate station 36+70 on S100. The preference would be to include this crossing within the conservation easement, but as non -credited, in order for the site to be reviewed and monitored if a crossing is eventually installed at this location. Another option would be to include the design and installation of this crossing during site construction. Allowing an easement break for a small crossing that could have limited project impact review with the new culvert could result in an inadequate and improperly installed structure that would result in adverse impacts upstream and downstream into the credited portions of the mitigation site. Response: WLS prefers to keep the easement break at the future location crossing instead of having the crossing as a non - credited area within the easement. This crossing will only be developed in the future if development occurs on the property. If development does occur, the crossing would be a DOT/utility crossing and therefore would need to be designed and permitted to regulatory specifications. 3. The downstream culvert at the end of S100 at station 67+90 is shown as a 36" CMP, much smaller than the structures upstream on this reach. Unless prohibited due to a change in landowners the preference would be to include a new properly sized and installed crossing at this location. By replacing this structure with an upgraded structure, it will reasonably preclude future problems associated with maintaining an old undersized structure. Response: This culvert will be replaced and has been appropriately sized and set at the correct elevations to promote stability and allow aquatic passage. 4. As for the I-40 culverts it looks like the channel design will repair the perched condition by bringing the water surface elevation back into the culvert invert. Additional armoring (below the substrate) of the outlet pool may be necessary to insure long-term stability. Outlet stability and downstream stability is the primary concerns at the I-40 culverts, due to the culvert length, slope, and watershed size aquatic organism passage is unlikely. Response: Further plunge pool details and symbology have been added to the plan set to show additional armoring. The additional armoring will also be clarified to the contractor. DWR Comments (Erin Davis): 1. DWR appreciates the discussion of potential surrounding land use changes throughout the document, including consideration of both rural and urban regional curves in the stream design. Response: Thank you. 2. Page 19, Section 3.6.3 - Figure 8 shows an existing culvert within the proposed CE along S200 (lower), but no culvert at the bottom of S200. This is inconsistent with the section text. Also, please verify that the existing culvert(s) to remain are properly sized and in good condition. Response: Figure 8 and the text have been updated. All culverts proposed to remain will be replaced with properly sized corrugated plastic pipe. 3. Page 20, Section 4 - This section notes that functional objectives will be measured to document project success. How will native woody debris be measured to document biological function success? How do the functional design objectives in Table 6 relate to the potential function uplift and measurement methods in Table 19? Response: WLS is not proposing that level 4 and 5 functional categories are measured. The text in Section 4 has been updated to reflect this. 4. Page 21, Section 4.1.1- This section states that restoration activities "will likely" provide functional uplift within the Level 4 and 5 categories. Please clearly note whether these categories will be included in monitoring to demonstrate project success. Response: Section 4.1.1 has been updated to clearly state that any Level 4 and 5 function -based parameters and monitoring activities will not be tied to performance standards nor are required to demonstrate success for credit release. Any Level 4/5 uplift is implied and anticipated by the restoration work. 5. Page 22, Table 7 - Under Landscape Connectivity, what animals drinking from the stream are being referenced? Is this the best example of biology benefits from landscape connectivity? Response: This section has been updated and now discusses the benefits of aquatic and terrestrial species migration. 6. Page 23, Table 8 - Six of the nine reaches show a reduction in length from existing to proposed creditable stream channel. Do the crossings account for the total differences or will the proposed stream design result in a reduction of jurisdictional waters? Response: Table 8 has been updated and now shows proposed uncreditable length in its own column. No mitigation credits were calculated outside of the conversation easement. 7. Page 24, Section 6 - Please confirm the 9,965 LF of stream restoration referenced includes 308 LF of non-credit stream restoration. Response: Table 8 has been updated and shows there is a total of 9,656.73 SMCs and 464.61 uncredited length. 8. Page 29 - During the IRT prospectus site walk, we discussed our concern about post - construction flow along S101, S102 and S103 where the streambed will be significantly raised. Flow gauges should be located to demonstrate sufficient flow throughout these reaches to meet performance standards. Response: Figure 10 shows a flow gauge located in S101, S102 and S103. These reaches will be monitored to ensure sufficient flow and that performance standards are met. 9. Page 29 - DWR appreciates the statement to minimize tree loss to the extent possible. From DWR's perspective this does not need to include protecting black walnut (site- wide comment). Response: WLS understands that black walnut should not be protected onsite. Black walnut will be removed as needed during construction and monitored post -construction to ensure it does not threaten successful establishment of planted trees. 10. Page 36, Section 6.4.1- UT to Little Fisher River was identified as a reference quality stream even with the disturbance noted? Response: Yes, the stream was reference reach quality and a good representation of a single -thread channel with a smaller drainage area. The disturbance was located downstream and was not included in the survey. 11. Page 37, Section 6.5 - There are no details or callouts in the design sheets for floodplain interceptors or grass swales. Response: These areas are represented in the plan set with the note, "stabilize connection into proposed channel." Additional details and design guidance will be added to the design sheets for these areas when grading is complete. 12. Page 38-39, Tables 16 & 17 - Please include wetland indicator status for species in both tables. Response: The wetland indicator status for each species has been added to both Tables 16 and 17. 13. Page 38, Table 16 - Were species present at the two stream reference sites considered in developing the planting list? Please clarify whether the Mixed-Mesic Forest and Alluvial Forest are two distinct target communities to be established within the project site or two community types used to develop a single target community for the project site. If two distinct target communities are proposed, Sheets 28 - 31 should show the different planting zones. Response: WLS did not utilize a reference vegetation site. The planting list was developed using relevant literature. There will be two distinct target communities and they are now shown on plan sheets 28-31. 14. Page 38, Section 6.6.1- DWR maintains that March 15th should be the planting target end date. Response: WLS proposed that the planting be completed by the start of the growing season in Catawba County, March 30th (per WETS data). The planting date has been updated in Section 6.6.1. 15. Page 39, Table 17 - The seed mix composition is primarily FAC/FACU. Given the existing wetland and proposed floodplain reestablishment, will these species provide adequate cover for the expected range of soil wetness conditions? Response: Table 17 species have been updated and now include species that are FACW, FAC and FACU. This will promote successful ground cover across a range of as -built conditions. 16. Page 39, Invasive Species - Will fescue be treated prior to or during construction? Response: In areas of undisturbed pasture WLS will assess fescue treatment options prior to planting. 17. Page 40, Section 6.7.1- On the as -built drawings, please callout depressional area locations (including partially filled channel/ditch areas) greater than 14 inches deep. Response: This language has been added to Section 6.7.1 and the depressional areas will be called out on the as -built plans. 18. Page 43, Jurisdictional stream flow - Please clarify that is an annual performance standard during the monitoring period. Response: Stream flow will be monitored and assessed annually during the monitoring period. 19. Page 43, Section 8.2 - Recommend rephrasing so stems counted aren't restricted to 3- yr, 5-yr and 7-yr old trees. Replanted stems can count towards success two years after planting. Response: Section 8.2 language has been updated so stem counted aren't restricted to 3, 5 and 7 year old trees and now can include replated and volunteers trees that are minimum two years old. 20. Page 44, Section 9.1- There are no Enhancement II reaches identified within this project. Response: This statement was outdated language from the prospectus and has been removed. All stream reaches in this project are proposed as restoration. 21. Page 46, Section 9.2 - Will there be undisturbed wooded preservation areas? Sheets 28 - 31 show the entire site being planted. Response: There will be a small amount of undisturbed wooded preservation areas. These areas are now shown on the design sheets 28-31 and in Figure 10. Final limits of preservation will be determined prior and during construction to minimize removal of desirable mature trees. 22. Page 48, Table 19 - Under Establish Riparian Buffer Vegetation, please note the vigor requirement. Response: The vigor (height) requirement has been added under Section 8.2 and updated in Table 19. 23. Figure 9 - There is no callout for the removal of the lower 5200 culvert shown on Figure 8. Please confirm. Response: There is a non-functional washed-out culvert at the downstream end of S200 below the limits of construction. The culvert is not impeding stream flow and will not be removed during construction. The callout in the design plans indicate this culvert will remain. Figure 9 and Section 3.4.2 has been updated to reflect this. 24. Figure 10 - a. Please show locations of proposed pressure transducers/crest gauges along 5100 and 5200 to adequately demonstrate bankfull events. Response: The locations of the crest gauges/transducers are now shown on Figure 10. b. Please note or show locations of proposed fixed photo locations, including at cross -sections, veg plots and stream crossings. Response: The photo point locations have been added to the stream crossings and a note has been added stating that cross - sections will also be used as photo point locations. c. There appears to be no veg plots proposed in existing wooded areas. Since all project streams are proposed for restoration, DWR would expect at least some of these wooded areas to be disturbed/cleared during construction and require replanting. Additionally, Sheets 28 - 31 show the entire conservation easement being planted. Please confirm that the number of veg plots meet the minimum monitoring criteria for the project planting area. If portions of the site will not be planted, please identify those areas on Sheets 28 - 31 and include a total area calculation reference in the mit plan narrative. Please redistribute veg plots to adequately cover the project site, including adding a plot to the 5100 section below the second crossing north of I-40. Response: Plan sheets 28-31 have been updated to show the approximate planting zones. Two more vegetation plots were added for a total of 24 plots. A plot has been added below the second crossing north of I- 40. The vegetation plots were redistributed across the site to adequately cover the project site. 25. Please add or modify a figure to show the locations of the two reference sites in relation to the project site. Response: Reference reaches are now shown in Figure 1a. 26. Sheet 1A - Is there a difference between the two j-hooks or two rock steps listed in the legend? Response: On the plan sheets the structures are drawn with their correct rock sizes. As the stream width increases downstream, more rocks are added to the structures. 27. Sheet 3A - What species are proposed for the live staking and toewood live cuttings? Response: Section 6.6.1 states that the species proposed for live staking are black willow and silky willow. 28. Sheet 2H - Please confirm the proposed culverts will be buried in compliance with DWR's GC-4134 general condition #11. Response: All proposed culverts have been updated and are in compliance with the DWR's GC-4134 general condition #11. 29. Sheet 2K - Have proposed ditch plug locations been identified? Response: Ditch plugs are used anywhere that the old channel crosses the proposed channel. The channel fill is shown in the design sheets. 30. Sheet 2L - Please confirm there is only one ditch callout for the project, Sheet 17. Response: There are two areas called out to be stabilized on Sheet 17 that are not a standard ditch. The standard ditch detail was added just in case the contractor needed to utilize it with guidance from the engineer. Additional details and design guidance will be added to the design sheets for these water quality treatment areas when grading in complete. There are six water quality treatment features for S100 and six water quality treatment features on S200 of active erosion due to overland flow and highway ditches on I-40. 31. Sheet 4 - Please provide context and construction details for the Berm. I don't believe this feature was mentioned in the plan narrative. Also, please callout the gravel drain feature noted in Section 6.2.1. Response: Additional details and design guidance will be added to the design sheets for the berm when grading is complete. 32. Sheets 4, 7, 9, 10, 17, 18, 19 - Please provide a typical detail(s) for the proposed "stabilize connections". Based on the total number of these features, I'm assuming these are the water quality treatment features noted in Section 6.5. Considering five of these features originate at or beyond the easement boundary, DWR is concerned that they may act as a simple rock lined conveyance which would bypass the reforested buffer meant to improve water quality. DWR would like to see a design that as described in the narrative will "dissipate energy and gradually step-down to the stable design streams," as well as trap excessive sediment inputs. Response: Additional details and design guidance will be added to the design sheets for these water quality treatment areas when grading in complete. The designs will dissipate energy and gradually step-down these areas based on the slope and drainage area that are in these areas to prevent gullying and erosion on the proposed stream. 33. Sheet 6 - Were alternatives to a smooth wall culvert considered? Are there any aquatic passage concerns with using smooth wall HDPE? Response: The proposed culverts were switched to corrugated plastic pipe. 34. Sheet 9 - Will the proposed constructed riffle adequately stabilize the easement break for the landowner's current site use? Response: Yes, this crossing is a potential future crossing that will not be utilized by the current landowner. 35. Design Sheets - Please show floodplain grading lines on the final plans. The narrative notes a minimum 1.5 bankfull width floodplain design in most areas, which DWR appreciates. DWR was also glad to see a gentler slope planned between floodplain and terrace areas where feasible. Response: A preliminary limit of disturbance has been added to the design plans to demonstrate a floodplain of an additional 1.5 bankfull widths on both sides of the restored channel for excavated areas. This will be represented in the final grading plans. All terrace slopes will be maximum 4:1 according to the typical sections on Sheet 2, unless local constraints dictate a steeper terrace slope. 36. Design Sheets - Is any fencing proposed? If so, please include an overall fencing concept plan with approximate locations of existing (to remain) and proposed fencing. Please ensure there is adequate safe access points for regulatory agency and long- term steward representatives to walk the site. Response: After the GIS figures you will now find a cattle exclusion plan. This plan shows where the proposed fencing will be located as well as proposed gate locations. Note: fencing will only be constructed at the direction of the landowner where they intend to continue livestock grazing. 37. DWR really appreciated the level of detail and site specific discussion provided in this project draft mitigation plan, particularly in the site constraints, regulatory considerations, and project risks and uncertainties sections. Response: Thank you. EPA Comments CTodd Bowers): Note: It is understood that site visits may have been made by IRT members and other project managers during the development of site feasibility to provide mitigation credit. In that regard, I feel it is necessary to mention that I have not been on -site during this process and that my comments may reflect a lack of on -site observation and evaluation. 1. General Comment: I really appreciate the sponsors consideration in addressing future development near and/or adjacent to the site within the drainage area for both of the main streams. Also appreciate the consideration of the potential widening of Interstate 40 in Catawba County as a very real possibility and that appropriate setbacks were utilized. Response: Thank you. 2. General Comment: I almost overlooked the site photos (Appendix H) which some may have been useful in the main body of the document to enhance the narrative. Great illustration of the many stressors on and instabilities of the streams in the Starker Project. Response: Thank you for the suggestion and we will plan to add more photos into the narrative in future mitigation plans. 3. Section 1.3/Page 6: The project does not involve stream enhancement as all streams are undergoing Priority 1 or 2 restoration. Response: Section 1.3 has been updated and now clearly states that the mitigation approach will be restoration. 4. Section 2.1/Page 7: The lat/long for the site is erroneous. Response: The lat/long has been corrected. 5. Section 3.4.2: Recommend reorganizing the stream nomenclature by addressing each stream segment by a name and reach #. The additional crossing language is confusing as there are multiple existing crossings along each main stem along with a new one that is being proposed. Example: S1 Reaches 1-5, S2 Reach 1, S2 Reach 2, S2 Reach 3 instead of "north of or "below" crossings. Consider renaming tributaries as S3, S4 and S5. Clearly identify each Reach segment on the maps of Figures 8 and 9. This will make all the tables much easier to read too. Response: At this time WLS already has an approved PJD for this project and have been told previously to not change the reach names after the PJD because it makes permitting difficult for the USACE. We will take the suggestion into consideration on future mitigation projects. 6. Figure 9: Stream lengths and credits do not match Table 8 in Section 5.1. Recommend that Restoration Priority 1 and 2 approaches are highlighted in Figure 9. Response: The table has been removed from Figure 9. Figure 9 as been updated to show should P1 and P2 approaches. 7. Section 3.6.3/Page 19: I appreciate the plain language that states that the 60-foot crossing widths are based on future development of adjacent parcels and not due to landowner preference. Response: Thank you. B. Section 6.1/Page 25: As the anticipated floodplain is between 50 to 70 feet along most of the project reaches, was the Conservation Easement width designed to encompass the stream floodplains? Response: The Conservation Easement width was designed to encompass the minimal buffer width based on current regulatory guidance. In most areas this will encompass the proposed floodplain width. The very downstream ends of S100 and S200 are on the Mull Creek geomorphic floodplain and the proposed easement will not encompass the entire floodplain width. 9. Section 6.1/Page 25: Along with topsoil stockpiling for reapplication in P2 restoration reaches is there any plan for soil amendments in these areas to promote vigorous plant growth? Response: If needed soil testing will be conducted during construction to determine if any soil amendments are needed to promote plant growth. The language in the relevant section has been updated. 10. Table 10: I am a bit suspect of the listed Drainage Areas that don't seem to change much moving downstream. I may have missed it, but I don't see design discharge (Max Q) listed anywhere in this table. I understand design discharge is well addressed in later tables (13 and 14). Response: The different reaches were broken into sub -reaches due to different design approaches. Therefore, there is some repetitive drainage areas in the table between the sub -reaches. 11. Section 6.2.1: Reiterating my comment on renaming the streams across the site to remove confusion between text, tables and figures. Sequentially numbering the Reaches along each main stem will reduce confusion with current and proposed crossings and locations. Response: At this time WLS already has an approved PJD for this project and have been told previously to not change the reach names after the PJD because it makes permitting difficult for USACE. We will take the suggestion into consideration on future mitigation projects. 12. Section 6.3.1/Page 32: Once again I appreciate the sponsors consideration of future development along with regional curves and reference reaches when designing the stream parameters. Response: Thank you. 13. Section 11/Page 49: "physical inspection of the site will take place at least once a year throughout the post -construction monitoring period" is in conflict with Section 7 that states: "Project will be monitored on a regular basis and a physical inspection of the Project will take place at least twice a year throughout the post -construction monitoring period until performance standards are met" Response: Section 11 has been updated to state that a physical inspection of the site will happen minimum twice per year until the performance standards are met. 14. Given the existing wetlands currently within the conservation easement and the potential for flooding in the downstream reaches near Lyle Creek, I recommend adding the wetland indicator status to each species being considered for planting. Recommend considering differing planting zones (currently a single zone) if significant hydrologic regimes exist or may develop along the riparian buffer within the easement. Recommend adding a simpler vegetation planting map as a Figure since the plan sheets were very cumbersome to view due to size. Response: The wetlands indicators have been added to Table 16 and 17. The plan set and Figure 11 now show the different planting zones. Please contact me if you have any additional questions or comments.

The proposed Bank is being developed as a private commercial umbrella mitigation bank to allow for the addition of future mitigation sites located in the Catawba River Basin, 8-digit Hydrologic Unit Code (HUC) 03050101 (Figure 2). The purpose of the Bank is to provide stream and wetland mitigation credits to compensate for unavoidable impacts to Waters of the U.S. authorized under sections 401 and 404 of the Clean Water Act, Section 10 of the Rivers and Harbors Act, and all applicable state statutes. The Project is providing 9,656.73 warm thermal regime stream mitigation credits and 29.91 acres of easement that will be protected in perpetuity. This mitigation plan was prepared in accordance with C.F.R. §332.1-8 (2008), Compensatory Mitigation for Losses of Aquatic Resources, and was based on current United States Army Corps of Engineers — Wilmington District (USACE) Guidance, which is subject to the approval of the USACE District Engineer (DE) in consultation with the North Carolina (NC) Inter -Agency Review Team (IRT). 1.2 Bank Sponsor WLS will serve as the Bank Sponsor for the WLS Catawba 01 Umbrella Mitigation Bank, Starker Mitigation Site. The contact information for the sponsor is listed below: Water & Land Solutions, LLC Attn: Catherine Manner 7721 Six Forks Rd, Suite 130 Raleigh, NC 27615 Phone: 919-614-5111 Email: catherine@waterlandsolutions.com 1.3 Mitigation Goals and Objectives The Project mitigation goals are to provide numerous water quality and ecological benefits within the Lyle Creek sub -basin and Catawba River watersheds. Major goals for the Catawba River basin, as described in the Catawba River Basin Restoration Priorities (RBRP; NCEEP, 2007, amended 2013) include: 1) improved management of stormwater runoff to Crowder and Catawba creeks, 2) protection of the critical water supply reservoirs in the region and their immediate riparian zones, and 3) land protection for important natural and cultural resource sites including the Bunker Hill bridge over Lyle Creek. The Project will: • Restore aquatic habitats that are currently degraded by cattle access and bank erosion. • Improve water quality by excluding cattle. • Restore riparian buffers. • Stabilize streams that are part of a WS-IV watershed. • Serve to continue existing water quality initiatives that are on -going in the watershed. Final Mitigation Plan Starker Mitigation Project Page 6 • Enhance/restore riparian wetlands by reconnecting the stream to its historic floodplain. In the Catawba River Basin wide Water Quality Plan (NCDWQ 2010), the Lyle Creek Watershed (03050101140010, Figure 1) is specified for protection efforts that include headwater streams that drain to Lake Norman, a water supply reservoir. As part of the proposed Project, 9,965 linear feet of stream (warm water thermal regime) will be stabilized and restored. The Lyle Creek watershed is 39% agricultural land, and a majority of Lyle Creek receives agricultural runoff. The proposed restoration work for the Project would restore riparian buffers at least 50 feet in width along all stream reaches. This proposed work will provide significant reductions in nutrients, sediment, and fecal coliform supplied to Mull Creek, Lyle Creek, and ultimately Lake Norman. To accomplish these goals, the following site -specific objectives will be measured to document overall project success: • Provide a floodplain connection to the incised Project stream reaches by lowering bank height ratios (BHRs) to less than 1.2, thereby promoting more natural floodplain storage and overbank flood flows, • Improve bedform diversity by increasing scour pool to pool spacing and depth variability, • Increase native species riparian buffer and wetland vegetation density/composition along streambank and riparian areas, • Improve aquatic habitat and fish species diversity and migration through the addition of in -stream cover and native woody debris, • Site protection through a 29.91-acre conservation easement with minimum 50-foot riparian buffers from the top of banks along all streams in perpetuity. The existing conditions site assessment suggests that the proposed mitigation activities will result in a higher functioning aquatic ecosystem. The project goals and objectives address water quality stressors by reducing nutrient and sediment inputs through stream restoration, riparian buffer restoration, and riparian wetland rehabilitation. Hydrologic functions will be improved by raising the local water table. The biologic and habitat functions will be improved by the revegetation of the riparian buffers. Additionally, a 29.91-acre conservation easement will protect stream reaches and aquatic resources in perpetuity. These mitigation efforts will provide a significant ecological benefit with minimal impacts and constraints during a recovery period that would not otherwise occur through natural processes. 2 Bank Establishment and Operation 2.1 Site Selection The Project site is located in Catawba County, North Carolina (35.727984°,-81.176076°). The site is part of the Catawba River Headwaters Subbasin, HUC 03050101 (Figure 1). The proposed site includes two unnamed tributaries to Mull Creek (5100 and 5200), Mull Creek drains into Lyle Creek and ultimately Lake Norman on the mainstem of the Catawba River. Mull Creek, near the project site, drains portions of the City of Conover and the Town of Claremont. Both municipalities are experiencing growth into surrounding rural areas, and the Project directly abuts both sides of Interstate 40 (1-40) between mile markers 133 and Final Mitigation Plan Starker Mitigation Project Page 7 135. The site is currently in agricultural use but is potentially a future commercial/residential development area. To get to the site from Raleigh get on 1-40 West. Use right three lanes to take exit 131 for 1-40 West towards 1-785 N/Greensboro/Winston-Salem. Take exist 133 for Rock Barn Rd, take a left and the site is located at the first right off of Rock Barn Rd, John Daniels Drive. 2.2 Service Area The proposed Geographic Service Area (GSA) for the Bank is illustrated in Figure 2 and will provide compensatory mitigation credits for unavoidable, permitted impacts to Waters of the United States in the Catawba River Basin (8-Digit HUC 03050101). Use of approved mitigation credits from the bank to compensate for impacts outside the GSA may be considered by USACE on a case -by -case basis. The Project will provide compensatory mitigation for warm stream impacts. Future sites may be developed in the Bank that provide both warm and cool stream mitigation credits as well as wetland mitigation credits. 2.3 Site Protection Instrument The Sponsor has obtained agent authorization forms and option agreements to purchase a conservation easement for each of the property parcels that comprise the Project. Copies of the agent authorization forms and draft conservation easement are provided in Appendix D. The Sponsor shall record a conservation easement with the Catawba County Clerk that has been approved by the USACE, in coordination with the IRT, and provide a copy of the recorded conservation easement to the USACE. The current property owner for the Project site is listed in Table 1 below. Table 1. Parcel Ownership Information 375210364087 375219523168 Hunsucker Farms, LLC 375215732614 29.91 03599/0062-0065 375216831456 375215534132 375211558910 The conservation easement will ensure that the site will be protected in perpetuity from land uses that are inconsistent with the UMBL Apart from USACE-approved activities (in coordination with the IRT), the site shall not be disturbed by activities that would adversely affect the intended extent, condition, or function of the bank. The conservation easement shall not be removed or modified without prior written approval of the USACE. 2.4 Watershed Need and Feasibility As a result of implementing this Project, WLS will restore and protect 9,965 linear feet of stream. The restoration will offset unavoidable impacts to Waters of the United States associated with rapid growth and development and improve and protect aquatic resource functions in the region. Final Mitigation Plan Starker Mitigation Project Page 8 The technical feasibility of the bank is assured due to WLS' extensive experience with stream and wetland restoration and enhancement in North Carolina and throughout the Southeast. Examples of WLS' success with stream restoration and enhancement include the WLS Neuse 01 Umbrella Mitigation Bank and the WLS Yadkin 01 Umbrella Mitigation Banks. The absence of fatal flaws, such as hydrologic trespass, and the absence of threatened and endangered species and their habitats means the project is unlikely to be impeded by resource issues, or by objections from landowners. 3 Baseline Information WLS performed an existing conditions assessment for the site by compiling and analyzing baseline information, aerial photography, and field data. The purpose of this assessment was to determine how aquatic resource functions have been impacted within the catchment area. Parameters such as watershed drainage area, percent impervious cover, land use, climate, and hydrology were evaluated. The following sub -sections further describe the existing site conditions, degrees of impairment, and primary controls that were considered for developing an appropriate restoration design approach. 3.1 Watershed Characterization 3.1.1 Surface Water Classification The site includes two unnamed tributaries to Mull Creek, which drains into Lyle Creek and ultimately Lake Norman. Lyle creek is listed as WS-IV (Water Supply IV- Highly Developed) and flows into Lake Norman, a water supply reservoir, approximately four miles downstream of the confluence of Mull Creek and Lyle Creek. 3.1.2 Jurisdictional WOTUS WLS investigated on -site jurisdictional WOTUS using the USACE Routine On -Site Determination Method. This method is defined in the 1987 USACE Wetlands Delineation Manual and subsequent Eastern Mountain and Piedmont Regional Supplement. Stream classification utilized the NCDWQ Stream Identification Form. Potential jurisdictional (JD) wetland areas as well as upland areas were classified using the USACE Wetland Determination Data Form. The results of the on -site field investigation indicated that all Project reaches were determined to be jurisdictional stream channels. In addition, five jurisdictional wetland areas were delineated within the proposed Project area (See Figure 8) located on floodplains (WA is 1.2 acres, WB is 0.03 acres, WC is 0.03 acres, WD is 0.03 acres, and WE is 0.04 acres). All of these jurisdictional wetlands are inside the proposed conservation easement. WLS received a preliminary jurisdictional determination (PJD) from the USACE in March 2021 and supporting documents and agency correspondence are provided in Appendix F. 3.1.3 NC SAM and NC WAM WLS completed stream and wetland assessments using the NC Wetland Assessment Method (NC WAM, Version 5.0, 2015) and NC Stream Assessment Method (NC SAM, Version 2.1, 2015). WLS evaluated the NC WAM and NC SAM metrics relevant to the Project wetland areas and stream reaches (See Appendix Q. The Project reaches all scored 'low' due to previous dredging, lack of buffer, and water quality stressors from agriculture, and altered stream morphology. Wetland area WA, WB, WC and WE rated 'medium' due Final Mitigation Plan Starker Mitigation Project Page 9 to some disturbed conditions. Wetland area WD rated 'low' due to poor habitat conditions. The ecological assessments also incorporated qualitative and quantitative observations using historic aerials, field evaluations, and detailed topographic survey data collected across the site. The conclusions from these assessments help describe the current stream and wetland conditions and functional ratings, however, these methods are not intended for determining mitigation success on the site. Table 2. NCSAM/NCWAM Summary Note: Three smaller sub -reaches (5101, 5102, and S103) were not scored due to minimal length in the project area. 3.2 Land Use and Development Trends A historical aerial review from 1951 to present (Figures 7a-7d) was conducted to document landscape changes in the watershed. Prior to the development of 1-40 in 1960 the area consisted mostly of row crop and pasture. In 1960, interstate 40 was built through Catawba county (Figure 7b) dissecting the project site. Other than the disturbance of 1-40, the land uses in this watershed have mostly remained stable since 1950, including the stream buffer surrounding the project site. It is anticipated this watershed will ultimately be developed and include residential single family and multi -family homes as well as light industrial space. A highway commercial space is also being developed on the property adjacent to the project site. 3.3 Landscape Characteristics 3.3.1 Physiography and Geology The site is in the Northern Inner Piedmont Level IV Ecoregion. This area has higher elevations with more rugged topography than other areas of the Piedmont as well as mostly mesic soils rather than thermic soils. More specifically, this area consists of Amphibolite and Biotite Gneiss ('CZab') (Geologic Map of North Carolina, NC Geological Survey, 1998). Streams in this area usually have a higher gradient than streams in the Outer Piedmont and contain mountain type macroinvertebrate species. (Griffith et al, 2002). 3.3.2 Soils Soils at the site were initially determined using NRCS soil survey data for Catawba County (NRCS Catawba County Soil Survey, 1975). As shown on the NRCS Soils Map (Figure 4), existing floodplain soils around the reaches are mostly within the mapping units TmD, TmC, TmB, TmE and CsA. TmD soils are described as Tomlin loam (10 to 15 percent slopes), TmC is described as Tomlin loam (6 to 10 percent) and TmE soils are described as Tomlin loam (15 to 25 percent slopes). TmD, TmC and TmE are found on hillslopes and ridges and the soils parent material is saprolite derived from diorite and gabbro or diabase or gneiss. TmB Final Mitigation Plan Starker Mitigation Project Page 10 soils are described as Tomlin loam (2 to 6 percent slopes) and are found on interfluves. CsA soils are described as Codorus loam (0 to 2 percent slopes), and these soils are found on floodplains and are frequently flooded, the parent material is loamy alluvium derived from igneous and metamorphic rock. On -site soils investigations were conducted to identify potential hydric soils in October 2018 by licensed soil scientist (LSS), Michael G. Wood, LSS with Three Oaks Engineering (See Hydric Soils Report in Appendix B). The findings were based on hand -turned auger borings and indicate the presence of hydric soils along the floodplains at the top of reach 5100. The hydric soils status is based upon the Field Indicators of Hydric Soils in the United States (USDA, NRCS, 2018, Version 8.2). 3.3.3 Climate Catawba County has a warm moderately humid climate with hot summers, minimal snowfall and no dry season (NRCS, 1975). The average growing season for the Project site is 205 days, beginning mid -April and ending in late October (NRCS Catawba County Soil Survey). The average annual precipitation in the Project area is approximately 49.2 inches with a consistent monthly distribution, except for convective storm events or hurricanes that occur during the summer and fall months. Over the past 48 months, the Rain gauge at Oxford Rs near Claremont, NC has recorded 119.31 inches of rain (USGS). 3.3.4 Existing Vegetation Historic land management surrounding the Project area has been primarily for agricultural purposes. Prior to anthropogenic land disturbances, the riparian vegetation community likely consisted of Mesic Mixed Forest (Piedmont subtype) in the uplands with Alluvial Forest and Piedmont Bottomland Forest in the lower areas and floodplains (Schafale, 2012). The existing vegetation within the Project area consists of open pastureland with a mature canopy with a limited understory adjacent to the streams (Table 3).

Mixed Hardwood Forest: The mature canopy is dominated by red maple, yellow poplar, red oak, white oak, and black walnut. Woody shrub species include papaw, black willow, black cherry, hazel alder, and spicebush. Vine species include honeysuckle and muscadine. Herbaceous species include various sedges, rush, fescue, and blackberry. Invasive Species Vegetation: The invasive species vegetation present on the Project site are primarily, Chinese privet, Japanese stiltgrass (Microstegium vimineum), kudzu (Pueraria montana), and multiflora rose (Rosa multiflora). Final Mitigation Plan Starker Mitigation Project Page 12 3.4 Existing Stream Conditions 3.4.1 Geomorphic Assessment WLS conducted geomorphic and ecological assessments of the Project reaches to determine the current stream function, channel stability, and the impact of past and current land use on the Project site's aquatic resources. From historical aerial research, evidence was found to demonstrate that most of the Project area has been heavily impacted from historic and current land use practices, including interstate highway development. A further review of topographic maps, field investigation of on -site features, similar stream and wetland reference conditions, and LiDAR survey data provide clear evidence that the existing channel patterns that appear to be indicative of valley signatures, valley slopes, and drainage basins that likely supported headwater stream and wetland systems with associated bottomland hardwood forest. The tributaries within the Project boundary flow directly to Mull Creek. The streams at the Project were broken down into nine reaches [S100 (N of 1-40, above crossing), S102, S103, S100 (N of 1-40, below crossing), S100 (S of 1-40), S101, S200 (N of 1-40), S200 (S of 1-40, above crossing), and S200 (S of 1-40, below crossing)] totaling approximately 9,965 linear feet of existing streams. Table 4 provides reach designations, approximate drainage area, stream status based on field analysis and NCDWR stream classification form score. Table 4.

Final Mitigation Plan Starker Mitigation Project Page 13 Table 5 characterizes the existing stream morphology based on general descriptions, channel evolution (Simon, 1989) and Rosgen stream classification (Rosgen, 1994). Table S. Existing Channel Morphology Summary 3.4.2 Existing Reach Descriptions S100 (North of 1-40, above crossing): Reach S100 begins as a deep gully near Rock Barn Road on the northern end of the property. The gully is approximately 12 to 15 feet deep, highly unstable, and has been used in the past as a dumping area for farm trash and waste. At the base of the gully system, several strong springs originate and form the -tip headwaters of the S100 system. Incision of the stream decreases downstream; however, the system is incised (BHR > 1.5) along its entire length. Large trees are present along the banks of the upper Reach S100 demonstrates the ability to portion of S100, but not along the lower portion. enhance riparian wetlands through stream From the middle portion of S100 to the end of the restoration and buffer plantings. reach, adjacent riparian wetland areas occur due to considerable discharge of groundwater along the adjacent toe of slopes. The function of these wetlands is being impacted by the incised stream condition Final Mitigation Plan Starker Mitigation Project Page 14 and frequent cattle access which is prevalent along the entire reach. S100 above the crossing ends at the inlet of a 24 inch diameter culverted crossing for a farm path which provides a downstream structural grade control point. S102: Reach S102 is a direct tributary to S100. S102 begins as a spring head approximately 100 feet upslope of and near the middle of S100 above 1-40. The reach is heavily impacted by cattle and sections of the streambanks have been completely trampled. The channel has been filled with sediment from the eroding banks, and flow is diffuse and impeded due to cattle crossing near the middle of the reach. There are crayfish and frogs in the reach, but the biological function of the stream has been severely impacted by sedimentation and habitat degradation. Reach S102 ends at its confluence with Reach S100. S103: Reach S103 is a short tributary to S100, which starts at a large headcut where the adjacent slope has failed. There was water flowing for much of its length during site visits, though the streambed sediments are largely influenced by large scale erosion of the adjacent upland soils. S100 (North of 1-40, below crossing): This reach begins at the culvert outlet below the farm path crossing. The pipe is perched due to a past headcut. As a result of the headcutting, incision along the reach is higher, resulting in greater sediment loss due to bank scour and mass wasting than in Reach S100 (above crossing). This section of S100 is predominantly wooded; however, trees along the riparian floodplain are relatively sparse and consist primarily of successional species. Cattle are constantly accessing the wooded areas for shade and multiple areas along this section of S100 and are active loafing areas with an over - widened channel and trampled banks. Anthropogenic channel modification is evident with the channel's location against the right side of the valley, creating areas of mass wasting with bank heights much greater than those associated with the remainder of the incised channel. The lower section of S100 closer to 1-40 has been fenced off from cattle and has been left for reforestation to occur; however, this area presents the most active channel evolutionary processes. Numerous tree falls exist and continue to occur where the channel is actively increasing meander width. Almost all outside bends are characterized by extremely high, vertical banks with larger trees precariously perched on top. The top third of these banks consist of exposed roots and overhanging banks with little to no surface protection or rooting depth at the lower elevations where channel interaction occurs. Where Reach S100 approaches the 72-inch diameter culvert under 1-40, the bank height ratio drops to a relatively stable condition and the substantial erosive forces no longer seem apparent, most likely due to the backwater effects the culvert during higher flows. S100 (South of 1-40): Reach S100 begins at the downstream outlet of the 72-inch diameter culvert under 1-40. The outlet is laid on a natural bedrock seam which is providing vertical stability, however the increased velocities at the outlet of this extremely long stretch of culvert are impacting the banks with localized scour. The upper portion of S100 below 1-40 is wooded along the right bank, but the forest along the left bank has recently been cleared, leaving only a thin line of trees. Cattle have been fenced out of this upper part of S100 south of 1-40. However, as with the lower portion of S100, many of the channel evolutionary processes are manifesting through mass wasting of outer bends and localized toe scour within riffle and run sections. Much of the upper section of S100 south of 1-40 contains tree falls and/or debris jams creating localized areas of unstable vertical banks up and down stream. As S100 begins to transition to the floodplain of Mull Creek, cattle access resumes, the riparian buffer is reduced, and human channel modification once again become apparent through channel straightening. Cattle are using several loafing areas where substantial shade exists, causing trampled banks. Almost all outer bends through this lower portion of S100 are characterized by nearly vertical banks covered by herbaceous vegetation with few moderately sized trees. An existing 36-inch diameter CMP farm culvert is in place towards the end of the reach which acts as a pinch point for the stream, causing localized scour and instability in the banks Final Mitigation Plan Starker Mitigation Project Page 15 up and down stream. Finally, the confluence with Mull Creek is vertically stable as Mull Creek has some bedrock controls within the vicinity of the confluence that would provide an excellent tie in point with minimal concern of future headcutting. S101: Reach 5101 is a direct tributary to 5100. 5101 begins as spring head approximately 100 feet upslope of and near the lower end of Reach 5100. The reach is not currently impacted by cattle but is incised and actively eroding. Efforts have been made by the landowner to prevent the headcut from worsening by filling the channel with logs and debris, but the channel still appears to be actively eroding and downcutting. Based on historical aerial imagery from 1951, it appears that 5101 could have been a functioning stream before the construction of 1-40. There is evidence that the watershed for the tributary was split by the highway and the stream was diverted into a ditch that flows into 5100 north of 1-40 below the crossing. Upstream of the jurisdictional break, the channel appears to have been straightened and filled. In addition to overland stormwater flow, 5101 is also fed by groundwater from several streambank seeps. Reach 5101 ends at its confluence with Reach 5100. S200 (North of 1-40): Similar to 5100 to Mull Creek, S200 to Mull Creek can be generally characterized as a sand -dominated transport channel that is spring fed, with significant incision, partial entrenchment, and undergoing many of the same channel evolution steps present in 5100 to Mull Creek. As with 5100, 5200 to Mull Creek has experienced stressors associated with agricultural practices: human channel modification, cattle access, and timbering. Reach 5200 north of 1-40 begins as a small wetland area that is fed by hill slope springs near the main farmhouse and buildings. At a 21-inch culverted farm crossing just downstream, the stream incises greatly due to headcutting that has migrated up the stream system to the culvert. From the farm crossing culvert down to near the NCDOT right-of-way for 1-40, the stream is highly incised with extreme bank heights and considerable ongoing scour erosion and mass wasting. Headcuts are actively moving through this reach. Approximately 50 feet upstream of the NCDOT right-of- way, the stream has formed an active wetland floodplain within the overly widened channel that is relatively stable; however, there is still some erosion along the adjacent terrace banks due to overland flow and runoff. S200 (South of 1-40, above crossing): This reach begins directly below the 1-40 right-of-way and flows approximately 583 feet to a culverted farm crossing. The reach appears to have over -widened in the past, perhaps due to heavy cattle access, but has now formed a relatively stable wetland floodplain at a lower elevation. The developing floodplain is dominated by herbaceous vegetation with little deep rooting woody vegetation established. Cattle have been excluded from the reach for some time, perhaps because of the high, steep streambanks that are still eroding in some locations. This section ends at a culverted farm crossing that appears to be appropriately sized, but is experiencing some erosion due to poor stabilization practices. Final Mitigation Plan Starker Mitigation Project Page 16 Reach 5200, like many of the project reaches, displays frequent erosion around outer meander bends due to land disturbance, channel incision, loss of buffer, and frequent cattle access. S200 (South of 1-40, below crossing): This section begins at the culverted farm crossing and extends down to the confluence of 5200 with Mull Creek. The culvert is a 60-inch CMP. The reach is highly incised along much of its length with considerable areas of bank scour and mass wasting. The upper 800 feet and lower 700 feet of the reach have sparse mature trees that offer limited riparian protection, and cattle have active access to these areas. The middle 1,300 feet of channel was cleared of trees in 2009, and the area along the left stream bank was converted to livestock pasture. The area along the right streambank has been left fallow and has repopulated with young successional tree species that are approximately ten years of age, including significant areas of Chinese privet. Much of the channel through the middle and lower portion of S200 is meandering and eroding, especially on the outside of meander bends. This ongoing evolution has left the outer bends characterized by steep, undercut banks with an herbaceous cover lacking sufficient surface protection or rooting depth. Where large woody trees are present and an overwidening of the channel exists, small areas of new floodplain are developing at a lower elevation. However, with the presence of vertical bedrock grade control, the only means of gaining stability will be to continually stress the outer bends until an appropriate meander width can be achieved. Towards the lower portion of 5200 there is a 36-inch diameter culvert that is not functional and has eroded around the culvert but is not disrupting flow. This culvert is outside the proposed conservation easement and is below the limits of construction and will not be replaced or repaired as part of the mitigation project. As 5200 approaches the confluence with Mull Creek, the channel appears to still be undergoing incision processes. The banks are more vertical with significantly less vegetation is present. The terminus for S200 will occur at the farm crossingjust upstream with the confluence with Mull Creek. This culverted crossing is currently providing the stable downstream grade control point and will serve as a stable end to the S200 to Mull Creek system. 3.4.3 Sediment Supply, Delivery and Storage 5100 and S200 are sand bed streams with gravel dominated riffles. The current farming activities, livestock access, lack of adequate natural woody riparian buffer vegetation, past land disturbances, and stream instability create a larger sediment supply through the project area. 3.5 Potential Site Constraints 3.5.1 Existing Easements on the Site The 1-40 corridor runs through the approximate center of the project area and bisects 5100 and 5200. The culverts beneath 1-40 will be control points for the proposed stream design work, and the design will tie into the elevations of the existing culverts. No additional flooding will be created within the 1-40 NCDOT right-of-way because of the project. The project engineer will coordinate with NCDOT to ensure the design is acceptable and the conservation easement provides suitable spacing for future ROW maintenance or expansion. The current ROW is approximately 350 feet wide at the culvert crossings. Final Mitigation Plan Starker Mitigation Project Page 17 3.5.2 Utility Corridors within the Site One power line easement is present to the north of 5100, but the easement is located outside of the proposed project limits. No other easements or significant constraints have been identified for the project. The Sponsor will coordinate with the landowner regarding future development access and utilities to utilize proposed easement crossings. There are no commercial or private airports within five miles of the project site. 3.5.3 Mineral or Water Rights Assurance There are no mineral or water rights issues within or adjacent to the Project site properties. 3.5.4 FEMA Floodplain Compliance and Hydrologic Trespass Review of the Federal Emergency Management Agency's (FEMA) National Flood Insurance Program's Digital Flood Insurance Rate Mapping (DFIRM) panel 3710375200J, effective September 5, 2007, found that 5100 and S200 are not regulated waters. There are no established Base Flood Elevations (BFEs), Floodways, or Flood Hazard Zones along the tributaries. However, portions of Mull Creek that 5100 and S200 flow into are regulated; therefore, the lower 300 ft of 5100 and S200 are within the flood hazard zone AE associated with Mull Creek. The proposed restoration work associated with this project will not include any structure placement, excavation, or fill within the Flood Hazard Zone significant enough to influence the BFEs of Mull Creek. A floodplain development permit is being prepared to submit to the local floodplain manager for work on 5100 and 5200. Due to the steep step pool system upstream on 5100 and 5200, hydrologic trespass will not occur. 3.5.5 Invasive Species Vegetation There are currently no substantial communities of invasive plant species within the proposed project boundaries; however, some areas of invasive species vegetation have begun to establish on S200 south of 1-40 above the crossing, mainly Chinese privet and Japanese stiltgrass. There is also an area of established Kudzu located on S200 north of 1-40 right above the DOT right of way. In addition, several small areas of multiflora rose plants were observed on the project site above 1-40. These areas will be monitored by WLS, and any invasive plants found within the project boundary will be treated to prevent expansion and establishment of a substantial invasive community. This will allow for a healthy, native riparian and upland plant community to dominate the area and help prevent future establishment of invasive species vegetation. 3.5.6 Potential Future Land -Use Future site constraints include, but are not limited to development, silviculture, and infrastructure maintenance. Historic aerial imagery indicates that the Project area has been used extensively for agricultural purposes. The surrounding areas remain in an agricultural community with some neighboring forested property. There is potential for the area surrounding the easement to be developed in the future. The project area is adjacent to 1-40 which could potentially be widened at a later date. To account for this possibility the conservation easement starts 25 ft from the start of the right of way. Project reaches were designed to be self -maintaining and resilient in a dynamic landscape. Riparian buffers in excess of 50 feet will protect the project reaches from changes in watershed hydrologic regimes. Final Mitigation Plan Starker Mitigation Project Page 18 3.6 Regulatory Considerations 3.6.1 Cultural Resources This project is not anticipated to have any adverse impacts on cultural or historical resources. On -site investigations and discussions with the landowner have not revealed any potential resources of this type on the property. EPR (consultant) conducted a search of the project area using the State Historic Preservation Office's HPOweb database. No structures listed on the NRHP, or those eligible for listing, were found in the project boundary or within a one -mile radius. The NRHP report can be found in Appendix G. 3.6.2 Threatened and Endangered Species Based on a review of the US Fish and Wildlife Service's (USFWS) Information for Planning and Consultation (IPaC) database, there are currently four federally -listed threatened or endangered species known to occur in the project vicinity: bog turtle (Glyptemys muhlenbergii), Schweinitz's sunflower (Helianthus schweinitzii), dwarf -flowered heartleaf (Hexastylis naniflora) and the Northern long-eared bat (Myotis septentrionalis). The Northern long-eared bat (NLEB) was recently listed as an endangered species and the Project is located within the USFWS habitat range and white -nose syndrome zone per Final 4(d) rule (USFWS, 2019). The Project site is not near any known hibernation or maternity sites, nor is Catawba County listed as one of the counties for confirmed hibernation and maternity sites. It is not anticipated that the proposed mitigation activities will take place within known hibernacula or remove known occupied maternity roost trees. WLS will coordinate with the appropriate agencies should a determination be required for permitting. The USFWS encourages avoiding tree cutting from May 15-August 15 if possible. Project implementation is not anticipated to have a negative impact on these species. EPR sent letters to USFWS and the NC Wildlife Resources Commission (NCWRC) and is in coordination concerning the Schweinitz's sunflower and dwarf -flowered heartleaf. A survey for Schweinitz's sunflower was conducted on September 29, 2020, with no individuals found. A survey for dwarf -flowered heartleaf was conducted on April 15, 2021, with no individuals found. EPR also conducted a one -mile radius search of the project area using the Natural Heritage Program of North Carolina (NCNHP) database and no occurrences were found in the project boundary. IPaC report, NCNHP report, USFWS response and NCWRC response can be found in Appendix G. 3.6.3 Conditions Affecting Hydrology Seven crossings must be accounted for in the stream design: two crossings will be removed near the origin of S200 (north of 1-40) and on S200 (south of 1-40, below existing crossing), three crossings will be replaced (two on 5100 and one on 5200), one potential future crossing will be added on 5100 (north of 1-40, below existing crossing) and one existing culvert will remain at the bottom of 5200 (Figure 8). The constructed crossings will allow livestock and farm equipment to access fields and pastures on either side of the stream reaches. The replaced or added culverted crossings will be range from 48" — 60" corrugated plastic pipe and are appropriately sized and set at the correct elevations to promote stability and allow passage of aquatic life. Stabilization practices will be applied to ensure stable crossings. The crossings are 60-feet wide and located in easement breaks to allow for future residential and commercial development. Final Mitigation Plan Starker Mitigation Project Page 19 3.6.4 Adjacent Land Use Site -adjacent land use is primarily silviculture and agriculture. However, the surrounding land use is transitioning to commercial, residential, and industrial land uses due to its proximity to several population centers and easily accessible transportation corridors. None of these land uses will have negative impacts on the function of the Project and the stream channel design contemplates the potential future runoff conditions. 4 Functional Uplift Potential Harman et al. (2012) provides a framework for conducting function -based assessments to develop project goals and objectives based on a site's restoration potential and functional uplift. The framework is based on the Stream Functions Pyramid (SFP) which is a conceptual model that can be used to better define project goals and objectives by linking them to stream functions. Stream functions are separated into a hierarchy of functions and structural measures, ranging from Level 1 to Level 5 and include the following functional categories: Hydrology (Level 1), Hydraulic (Level 2), Geomorphic (Level 3), Physiochemical (Level 4), and Biological (Level 5). Function -based goals and objectives were considered that relate restoration activities to the appropriate parameters from the SFP framework, which are based on existing conditions, site constraints and overall restoration potential. To accomplish these site -specific goals, the following functional objectives of level 1-3 will be monitored to document overall project success as described in Table 6. Table 6. Function -Based Goals and Objectives Summary Improve Base Flow Reconnect Floodplain / Increase Floodprone Area Widths Improve Bedform Diversity Increase Lateral Stability Establish Riparian Buffer Vegetation Improve and/or remove existing stream crossings and restore a more natural flow regime and aquatic passage. Lower BHRs to <1.2 and increase ERs to >_2.2 Increase riffle/pool percentage and pool -to - pool spacing ratios. Reduce BEHI/NBS streambank erosion rates comparable to reference condition and stable cross-section values. Plant or preserve native species vegetation a minimum 50' wide from the top of the streambanks with a composition/density comparable to downstream reference condition. 4.1.1 Restoration Potential and Project Benefits Summary Restoration projects commonly provide functional lift of Level 2 and 3 parameters. To achieve goals in Levels 4 and 5, a combination of reach scale restoration and upstream watershed health must be measurable and sustainable. Final Mitigation Plan Starker Mitigation Project Page 20 It is expected the Project will reduce pollutant loads, including sediment and nutrients, improving overall aquatic functions. Given the landscape position and catchment size, the restoration activities will likely provide functional lift within the physicochemical and biological functional categories. However, Level and 5 function -based parameters and monitoring activities will not be tied to performance standards nor required to demonstrate success for credit release. The Project will provide numerous water quality and ecological benefits within the watershed. While many of these benefits focus on the Project area, others, such as nutrient removal, sediment reduction, and improved aquatic and terrestrial habitat, others have more far-reaching effects that extend downstream. The expected project benefits and ecological improvements are summarized in Table 7. Final Mitigation Plan Starker Mitigation Project Page 21 Table 7. Project Benefits Summary Restoring and enhancing 50-foot natural riparian buffers and alleviating concentrated flow points will decrease the volume and intensity of runoff into the system. Restoration practices will restore proper floodplain connection by establishing stable bank height ratios and entrenchment ratios. Floodplain connectivity will allow for more surface area for surface storage and retention. Raising and reconnecting the restored stream bed will promote higher water table conditions and more hyporheic exchange. A stable sinuosity for valley type and slope will allow for a natural self-sustaining system. Decreasing stream bank erosion, connecting with the floodplain, and excluding cattle from the stream will decrease the sediment coming from the restored system into Mull Creek. Restoring and enhancing 50-foot natural riparian buffers will allow for canopy cover and large woody debris in the system. The use of woody in -stream structures will ensure channel stability while also providing large woody debris. Benefits will be achieved by the exclusion of cattle from streams and restore functional buffers of sufficient width along all stream reaches to provide nutrient reductions. Benefits will be achieved by exclusion of cattle from the stream, restore functional buffers of sufficient width along all stream reaches, and stabilize stream bank erosion to provide sediment reductions. Benefits will be achieved by Restored buffers which will provide shade, reduce water temperatures, and increase dissolved oxygen concentrations. The restored stream bed will promote higher water table conditions and facilitate denitrification. Benefits will be achieved by restoration of appropriate habitats, reduce sediment and nutrient loads, exclude cattle from streams, and provide increased shading and organic material inputs for aquatic organisms. Benefits to landscape connectivity will be achieved by restoring a healthy stream corridor, promoting aquatic and terrestrial species migration and protecting their shared resources in perpetuity. Final Mitigation Plan Starker Mitigation Project Page 22 5 Determination of Credits The Project consists of all Stream Restoration to achieve the highest ecological lift possible. The proposed mitigation credit types, ratios and design approaches were discussed with the IRT during the prospectus site visit and described further in the meeting minutes located in Appendix G. 5.1 Proposed Mitigation Credit Types Proposed mitigation credit types are Restoration Stream Mitigation Credits (SMCs) (warm thermal regime). See Tables 8 for the proposed credit summary. Table 8. Proposed Stream Mitigation Credits (SMCs) Stream Restoration 1,127 1,169.54 68.69 1:1 1,169.54 (PI/P2) Stream Restoration 98.96 1:1 98.96 110 25.44 (P2) Stream Restoration 56.44 1:1 56.44 81 0 (P2) Stream Restoration 2,490 2,117.61 103.41 1:1 2,117.61 (PI/P2) Stream Restoration 1,829 1,888.07 85.88 1:1 1,888.07 (PI/P2) Stream Restoration 79.57 1:1 79.57 96 0 (P2) Stream Restoration 785 704.85 56.18 1:1 704.85 (P2) Stream Restoration 550 491.16 110.61 1:1 491.16 (P1) Stream Restoration 2,897 3,050.53 14.40 1:1 3,050.53 (PI/P2) Note: No mitigation credits were calculated outside the conservation easement boundaries. 5.2 Credit Release Schedule All credit releases will be based on the total number of mitigation credits generated as reported in the approved mitigation plan and verified by the as -built survey. The initial credit release will be based on the proposed stream mitigation credits (SMCs) as approved in the final mitigation plan. The credit ledger will be managed by WLS and approved by the USACE District Engineer (DE) and IRT. The estimated credits will Final Mitigation Plan Starker Mitigation Project Page 23 be released following current USACE guidance, as shown in Table 9 below. For example, 10% of SMCs will be withheld until four bankfull events, in separate monitoring years, have been documented. The initial credit release milestone shall include: approval of UMBI, approval of final mitigation plan, securing the Project site, financial assurances delivery, long-term protection mechanism delivery, title opinion delivery, and issuance of 404/401 permits necessary for construction.

WLS's comprehensive design approach utilizes common restoration practices and will appropriately address the jurisdictional streams and wetlands at the site, including protecting or enhancing riparian buffers along all of the Project stream reaches and wetlands, thus providing the maximum functional uplift with the goal of returning natural/historic functions to a former degraded aquatic resource. The design approach and mitigation work plan are described in the following subsections. Final Mitigation Plan Starker Mitigation Project Page 24 6.1 Design Approach The Project involves the restoration of approximately 9,965 feet of stream (Figure 9). The proposed Project will improve the function of existing wetland systems and restore a stable headwater stream - wetland complex. Aquatic resources on the site have been severely impacted by past channelization, ditching, direct cattle access, loss of riparian buffers, and past land use. S100 and S200, including S101, S102 and S103 are highly degraded and moderately to highly incised due to past channelization and/or natural stream incision in response to land use changes. The design approach for the entire length of S100 and S200 will involve reconnecting the streams to active floodplains (Priority Level I and II Restoration Approaches), with a preference for Priority Level I Restoration when feasible. No wetland credit is requested for WA due to its small size and existing jurisdictional status. There will be minimal functional uplift in WA and therefore it is not a viable addition to the bank. By reconnecting the streams to a functional floodplain, the following functional improvements will be achieved: ■ Rehabilitation of Adjacent Riparian Wetlands— Based on observed soil profiles that are exposed along eroding stream banks, it is apparent that wetlands were once prevalent along much of the Project reaches. Numerous groundwater springs discharge along the toe of adjacent hill slopes, and in some areas are still enough to support degraded wetland habitats. Raising of the stream beds and reconnection to an active floodplain will promote higher water table conditions adjacent to the streams and more overbank flooding. ■ Filtration of Flood Flows — Currently, discharges significantly higher than the bankfull discharge are carried within the incised stream channels. Reconnection to an active floodplain will provide filtration of flood flows through floodplain vegetation, effectively reducing storm flow energies and velocities. ■ Improved Buffer Function — Higher water table conditions associated with reconnecting the floodplain will promote better denitrification of groundwater flowing to the stream channels. Rehabilitated wetland areas adjacent to the stream will promote increased plant uptake and retention of surface runoff before reaching the stream channels, minimizing overland flow velocities while also encouraging nutrient removal processes. ■ Reduced Water Quality Impacts — By simply excluding livestock from the project stream using fencing and restoring riparian buffers, significant reductions in direct input of nutrients and fecal coliform will be achieved. Design approaches will ensure that all excavated floodplain areas allow for the design meander belt width, plus an additional 1.5 bankfull widths. For most project reaches this equates to a design floodplain width of between 50 to 70 feet. This width is considered practical and achievable based on available floodplain widths measured in the field. In some locations, natural pinches in the valley topography may necessitate tighter floodplain widths. For excavated floodplain areas, depths will be undercut so that excavated topsoil can be replaced to approximately 8 to 10 inches in depth to achieve final design floodplain grades. Native organic topsoil will be stockpiled separately during construction activities to be used in the replacement of topsoil in excavated areas. The slopes between the outer edge of the floodplain grading and the terrace will be a maximum of 4:1 unless natural hill slope topography dictates the need for steeper slopes. If needed, soil testing will be conducted to determine if soil amendments are necessary to promote plant growth. Final Mitigation Plan Starker Mitigation Project Page 25 In -stream structures will be constructed from materials naturally found at the project site, such as hardwood logs and brush, supplemented with the use of quarried rock and stone as needed. WLS will use methods of structure design and construction that have proven successful on numerous past projects, and practices that have been well received by regulatory agencies. The design approaches for the reaches were determined using drainage areas, regional curve analysis, slopes, and site constraints. The construction drawings provided in Appendix A describe the proposed construction methods including channel sizing, planimetric geometry, slopes, instream structures, and elevations of all pertinent features. Data characterizing the existing, proposed, and design morphological characteristics for each reach can be found in Appendix C. The design approach for each reach is described in the table and sections below. 6.2 Design Criteria Selection The design criteria (Table 10) were selected based off the regional curve analysis, reference reach data, and professional judgement as described in Section 6.4. Site constraints and slopes for each reach are described in Table 10 and the following sections. Table 11 provides the design stationing for reach designations.

S100 begins as a highly incised channel that becomes less incised as it flows downstream and opens into an alluvial valley. The extreme incision at the upstream end of the reach will be addressed by routing storm flows from the ephemeral drainage upstream through the existing gully on the east side of the headwater system. Reach 1 is a step -pool channel through the existing gully on the east side of the headwater system that will consist of rock step structures and constructed riffles/cascades to step storm flows down to the existing streambed elevation. The western gully will be stabilized by installing a gravel drain at the existing channel elevation that will continue to transport spring flow to the channel, and then filling and sloping the gully over the gravel drain to stabilize the area without needing to remove any of the large trees along the top of the bank. Downstream of the stream head, Reach 2 will begin and the bed elevation of the stream will be raised over a distance of approximately 370 feet to reconnect the stream with its original floodplain and is designed as a Bc channel due to a constrained valley. Fill material will be taken from adjacent upland areas to raise the streambed, and constructed riffle structures will be installed to ensure bed stability. Woody structures such as toe wood and log vanes, along with bioengineering practices, will be used to stabilize the outside meander bends and other areas of high bank stress. Downstream of the constrained valley, reach 3 begins and is designed as a C channel as the design pattern will follow a meandering plan form through the alluvial valley. This Priority Level I Restoration will be carried down to the farm crossing. S100 (North of 1-40, below crossing) This section of S100 is broken into two design reaches described below. Due to the highly incised and unstable nature of these stream reaches, a Priority Level I and 11 Restoration approach is proposed that will both raise the stream bed elevation and lower the adjacent floodplain slightly to restore floodplain access. Excavation of a floodplain at a lower elevation is the most practical approach to restoration since a significant amount of fill material would be required to raise the streambed and stabilize eroding banks and hill slopes. This approach also provides the opportunity to remove upland alluvial sediments that have been deposited on the floodplain as a result of poor land use practices in the past, thus exposing the buried hydric soil layers that are present along the reaches. Exposing the buried hydric soils, raising the local water table by raising the streambed, and providing for greater floodplain storage will provide significant uplift of lost riparian wetland function. The existing farm crossing culvert at station 21+94will be replaced with a 48-inch diameter corrugated pipe. There is a second break in the conservation easement at station 37+00, this easement break is for a potential future crossing. No crossing will be constructed in this location at this time. Reach 1 will be designed as a C channel and the design pattern will follow a meandering plan form through the alluvial valley. This reach section will be carried down until it is needed to drop to connect back into the existing 1-40 culvert. Reach 2 will be designed as a B channel with frequent pools, constructed riffles, rock structures, and steps to dissipate energy. S100 (South of 1-40) This section of S100 design is similar to that used for S100 north of 1-40, below the existing crossing, and is broken into two design reaches described below. The restoration approach will begin by raising the elevation of the stream to the culvert. Due to the highly incised and unstable nature of these stream reaches, a Priority Level II Restoration approach is proposed to both raise the stream bed elevation and lower the adjacent floodplain slightly to restore floodplain access. Excavation of a floodplain at a lower elevation is the most practical approach to restoration since a significant amount of fill material would be required to raise the streambed and stabilize eroding banks and hill slopes. This approach also provides the opportunity to remove upland alluvial sediments that have been deposited on the floodplain as a result of poor land use practices in the past, thus exposing the buried hydric soil layers that are present along the reaches. Exposing the buried hydric soils, raising the local water table by raising the streambed, and providing for greater floodplain storage will provide significant uplift of lost riparian wetland function. Reach 1 will be designed as a C channel and the design pattern will follow a meandering plan form through the alluvial valley. This reach will be carried down until it is needed to drop to connect back into the existing farm culverts at the end of S100. Reach 2 will be designed as a B channel with frequent pools, constructed riffles, rock structures and steps to dissipate energy. S101 and S102 Due to the incised and unstable nature of these stream reaches, a combination of Priority Level I and II Restoration approaches are proposed that will raise the stream bed elevation to restore floodplain access. This approach also provides the opportunity to raise the local water table, providing for greater floodplain storage and a significant uplift of lost riparian wetland function. Downstream of the stream head for both reaches, the streambed elevation will be raised to reconnect the stream with its original floodplain. Fill material will be taken from adjacent upland areas to raise the streambed, and constructed riffle structures will be installed to ensure bed stability. Woody structures such as toe wood, along with bioengineering practices, will be used to stabilize the outside meander bends and other areas of high bank stress. The design pattern will follow a meandering plan form through the alluvial valley. This Priority Level I Restoration will be transitioned down to the confluences with S100 using shallow Priority Level II Restoration only where/if needed. While this restoration approach requires the removal of some trees along the reaches, tree loss will be minimized to the extent possible. In many areas, the approach can be applied while working around larger Final Mitigation Plan Starker Mitigation Project Page 29 trees that would provide shade and organic material to the stream after restoration. Trees are most dense along the lower portion of S100 north of 1-40 below the crossing; however, tree loss due to bank erosion in this area is significant under existing conditions. These stream reaches are attempting to form active floodplains at a lower elevation but are early in the evolutionary process. Therefore, considerable erosion, mass wasting, and tree loss will continue before the system would begin to approach stability on its own. S103 Due to the unstable nature of this stream reach, a combination of Priority Level I and II Restoration approaches will raise the stream bed elevation to connect to S100 using shallow Priority Level 11 Restoration only where/ if needed. The stream will be designed as a step -pool channel that primarily follows the existing channel alignment. Rock step structures and a constructed cascade will be used to step storm flows down to the S100 design streambed elevation. S200 (North of 1-40) This section of S200 is broken into two design reaches described below. This section is the most incised of all the project reaches. Restoration will begin above the culverted farm crossing at the beginning of the reach, where the existing 21 inch diameter culvert crossing will be removed, and the farm path re-routed to above the reach as part of the project. Reach 1 will be designed as a step -pool channel that consists of rock step structures and a constructed cascade that will be used to step storm flows down. Reach 2 is designed as a B channel with a Priority Level II Restoration approach, involving raising the stream bed several feet and excavating a bench in some areas along the right stream bank, which has minimal large trees. Reach 2 primarily follows the existing channel alignment, due to the higher slope of the reach and the need to tie into the 1-40 road culvert at the downstream end of the reach. Rock structures and constructed riffles/cascades will be used along the reach to ensure bed stability and to arrest channel incision and headcutting that is currently occurring along the reach. Near the downstream end of the reach above 1-40, stable benches have already formed along the stream; therefore, in this location, stabilization practices will focus on minimizing future downcutting and treating eroding side slopes. S200 (South of 1-40, above crossing) This section of S200 will be broken into two design reaches described below. The restoration approach will begin by raising the elevation of the stream to the culvert. The design floodplain will connect into the existing benches that have formed to provide better floodplain connection. Constructed riffle structures will be installed to ensure bed stability. Reach 1 is designed as a meandering C channel. Woody structures such as toe wood and log vanes, along with bioengineering practices, will be used to stabilize the outside meander bends and other areas of high bank stress. The design pattern will follow a meandering plan form through the alluvial valley. Reach 2 is designed as a Bc channel due to a constrained valley going into the proposed farm crossing. This Priority Level II Restoration will be carried down for both reaches. Some areas of invasive species vegetation have begun to establish, mainly Chinese privet and Japanese stiltgrass. Treatment of invasive species vegetation will be included under the restoration approach. The culvert crossing is a 60-inch smooth wall HDPE. S200 (South of 1-40, below crossing) This section of S200 will be broken into two design reaches described below. The restoration approach for this reach will be the same as the approach described above for S100 south of 1-40. However, this section of S200 has few mature trees along its length since trees were timbered along much of the reach within the past 10 years. Within this cutover area, young successional species have begun to establish along the reach, along with a considerable amount of Chinese privet. Treatment of invasive species vegetation will be included under the restoration approach, as well as minor benching along this reach to Final Mitigation Plan Starker Mitigation Project Page 30 provide floodplain reconnection, which will promote the restoration of adjacent riparian wetland functions. 6.3 Flow Regime A majority of stream miles (>80 percent) in North Carolina are classified as headwater streams (drainage area <3.9 mi2), however, less than 10 percent of the 284 USGS stream gages in North Carolina are located on headwater streams (EFSAB, 2013). WLS recognizes the importance of these stream flow variables and the ecological role they play in supporting high functioning steam and wetland systems, especially in urbanizing watersheds. As such, flow monitoring will be conducted to demonstrate that the restored stream systems exhibit seasonal base flow during a year with normal rainfall conditions. The surface flow documentation methods are further described in Section 9. Table 12 summarizes the basic flow levels and ecological roles the restoration design will provide after Project implementation. Table 12. Flow Level and Ecological Role -Provide year-round habitat for aquatic organisms (drying/inundation pattern) -Maintain suitable conditions for water temperature and dissolved oxygen -Provide water source for riparian plants and animals -Enable movement through stream corridor and refuge from predators -Support hyporheic functions and aquatic organisms -Shape and maintain physical stream channel form -Create and maintain pools, in -stream and refuge habitat -Redistribute and sort fine and coarse sediments -Reduce encroachment of vegetation in channel and establishment of exotic species -Maintain water quality by flushing pollutants -Maintain hyporheic connection by mobilizing bed and fine material -Create in -channel bars for seed colonization of native riparian plants -Deposition of fine sediment and nutrients on floodplain -Maintain diversity, function, and health of riparian floodplain vegetation -Create streamside habitat, new channels, sloughs, and off -channel rearing habitat through lateral channel migration and avulsion -Recharge floodplain and storage processes -Recruitment of native wood and organic material into channel 6.3.1 Regional Curve Comparison Regional curves developed by Dunne and Leopold (1978) relate bankfull channel dimensions to drainage area and are based on the channel forming discharge theory, which states that one unique flow can yield the same channel morphology as the full range of flows. Gage station analyses throughout the United States have shown that the bankfull discharge has an average return interval of 1.5 years or 66.7% annual exceedance probability on the maximum annual series (Dunne and Leopold, 1978; Leopold, 1994). Hydraulic geometry relationships are empirically derived and can be developed for a specific river or extrapolated to a watershed in the same physiographic region with similar rainfall/runoff relationships (FISRWG, 1998). The NC Rural Piedmont Regional Curve (Harman et al., 1999), unpublished NC Piedmont Regional Curve (NRCS, Walker, private communication, 2015) and NC Urban Piedmont Regional Curve Final Mitigation Plan Starker Mitigation Project Page 31 (Doll, 2002) were used for comparison when estimating bankfull discharge. The NC Rural and Urban Piedmont Regional Curves and bankfull hydraulic geometry equations are shown in Table 13. Table 13. North Carolina Rural and Urban Piedmont Regional Curve Equations Qbkf = 55.31 Aw" R2=0.97 Qbkf = 89.04 Aw 0.12 R2=0.91 Qbkf = 306.80 Aw 0.63 R2=0.94 Abkf = 19.23 Aw 1.61 R2=0.97 Abkf = 21.43 Aw 0.68 R2=0.95 Abkf = 60.34 Aw 0.61 R2=0.95 Wbkf = 17.41 Aw0.31 R2=0.79 Wbkf = 11.89 Aw0.43 R2=0.81 Wbkf = 24.39 Aw0.33 R2=0.88 Dbkf = 1.09 Aw0.29 R2=0.80 Dbkf = 1.50 Aw0.32 R2=0.88 Dbkf = 2.43 Aw0.33 R2=0.87 It's important to note these tributaries are classified as first and second order streams, and generally smaller headwater streams can be poorly represented on the regional curves. Based on our experience, both the published Rural and Urban NC Piedmont Regional Curve Equations overestimate bankfull discharge and channel dimensions for smaller ungaged streams, such as those present at the Project site. Due to the development occurring within the project watershed, WLS compared both the NC Piedmont Rural and Urban Regional Curves to assist in the channel design process. The proposed channel geometry was adequately sized to accommodate both current and potential future development by allowing natural channel responses over time without compromising overall stability. Throughout many of the project reaches, WLS increased channel cross sectional geometry slightly above thresholds in both the unpublished and published rural regional curves, but still within acceptable confidence intervals. This approach will allow project reaches to adapt to changing watershed conditions (i.e. increasing imperviousness) and climate fluctuations while still allowing frequent storm events access to floodplains during flows above bankfull, and maintain a healthy aquatic and terrestrial ecosystem. 6.3.2 Channel Forming Discharge A hydrologic analysis was completed to estimate and validate the design discharge and channel geometry required to provide more frequent overbank flows and floodplain inundation. Cross -sections were identified and surveyed to represent reach -wide conditions. Additional bankfull estimation methods, such as the commonly accepted Manning's equation, were compared to help interpret and adjust field observations to select the appropriate design criteria and justification for the design approach. The bankfull flows in gaged watersheds within the NC Rural Piedmont study documented return intervals (RI) that range from 1.1 to 1.8, with a mean of 1.4 years (Harman et al, 1999). EPR also compared the 2- year flow frequency using the published USGS regression equation for small rural streams (DA <_3 mil) within the Piedmont hydrologic area of North Carolina (USGS, 2014). As expected, these values fall slightly above the published bankfull discharge, but were extrapolated to represent a wider range of flows. WLS then compared lower flow frequencies in the 1.0-yr, 1.2-yr, and 1.5-yr RI range versus survey data, and field observations (See Appendix C).

Note 2: Unpublished Revised NC Rural Piedmont Regional Curve developed by NRCS (A. Walker personal communication, 2015). Note 3: Bankfull discharge estimates vary based on Manning's Equation for the representative riffle cross -sections. Bankfull stage roughness estimates (n-values) ranged from approximately 0.020 to 0.023 based on channel slopes, depth, bed material size, and vegetation influence. Note 4: USGS rural regression equation for 2-year flood recurrence interval, Q2 =163(DA)^0.7089*10^(0.0133*(IMPNLCD06)) for small rural streams (USGS, 2011) Note 5: NC USGS rural regression equation extrapolated for 1.2- and 1.5-year flood recurrence interval (USGS, 2011) After considering these estimation methods and results (geometry measurements, regional curves, flow frequency and USGS regional regression equations), WLS estimated the design discharge using values between the published NC Rural and Urban Piedmont Regional Curves and Manning's equation to select the appropriate design dimensions and flows rates that best correspond to the design channel that will convey the 1.2-yr to 1.5-yr RI. The design discharge analysis summary is provided in Appendix C. Final Mitigation Plan Starker Mitigation Project Page 33 6.3.3 Channel Stability and Sediment Transport Analysis A channel stability and sediment transport analysis was performed to ensure that the stream restoration design creates a stable channel that does not aggrade or degrade over time. The existing reaches exhibit signs of degradation rather than aggradation. Sediment supply to the Project is expected to be transportable since there is little evidence of aggradation within the Site. The shear stress and maximum particle size entrained were calculated and compared with the sub -pavement and pavement/active riffle samples collected from the existing reaches as shown in Appendix C. Particles will be entrained near the riffle d50 and d84 during a bankfull flow event. This analysis provides evidence that the stresses predicted for the design channels will be within the range of stable values calculated for similar stream systems. The full sediment transport analysis is provided in Appendix C along with the sub -pavement and pavement sample results.

However, the dataset used to create the regional curve only contains two sites with drainage areas less than 2 square miles. Additionally, data collected in Surry County indicates that the rural Piedmont regional curve may overestimate bankfull dimensions for sites with drainage areas less than 10 square miles. Rather than relying on a single reference reach for design criteria, the design criteria applied to the Project are based on surveys of multiple reference reaches conducted in the past, two new reference reach sites (described below), published reference reach data, and design criteria and monitoring data from past successful restoration projects performed throughout the Piedmont region of North Carolina. Reference data compiled and presented by Lowther (2008) for similar stream types, drainage areas, and slopes within the Piedmont of North Carolina were reviewed to evaluate appropriate ranges of sinuosity and pattern data. Lowther evaluated 19 reference reach streams across the Piedmont of North Carolina — our assessment only focused on the streams in the western portion of the presented data set that were closest to the project site. Because the ranges provided by this analysis were quite wide, EPR evaluated this reference information against past completed stream restoration projects that have performed well and have been tested by significant storm events. For the smaller streams on the project site, two potential reference sites were located, both of which are on private property and require permission to access. The first site, UT to Paul's Creek, has a drainage area of 0.14 square miles and is located northwest of Mount Airy. The site had consistent bankfull indicators throughout the reach but was impacted by a gravel road running down the hillslope to a neighboring agricultural field. Rapid methods were used to collect a riffle cross-section and the difference between water surface and bankfull features to provide a small drainage area point to the regional curve data. The second site, UT to Little Fisher River, has a drainage area of 0.02 square miles and is located southwest of Mount Airy. The UT to Little Fisher River reference site was surveyed in detail and was separated into two reaches and EPR collected longitudinal profiles and cross sections within both reaches. While there was flowing water in both reaches, the two reaches are separated by a dry section of channel (14 feet in length) where the flow was subterranean during both site visits. The upstream reach (riffle 1 and pool 1) was within a colluvial valley draining to the large Little Fisher River floodplain. The downstream reach (riffle 2) consisted of 40 feet of a single -thread sandy channel on the Little Fisher River floodplain before a collapsed pedestrian/ATV crossing disrupts the channel and the flow disperses into a wetland. Geomorphic data are summarized for both of these reaches below. Reference reach locations can be seen on Figure 1a. Table 16.

Lns/Wbkf Note 1: Composite reference reach values and ratios were compared using the stable streams described above. Note 2: Reference reach data was collected at UT to Fisher, and UT to Paul's Creek respectively. 6.5 Water Quality Treatment Features There are six areas for S100 and six areas on S200 of active erosion due to overland flow and highway ditches on 1-40. To stabilize these eroding areas, water quality treatment features are proposed in the form of floodplain inceptors, berms and matted grass swales to dissipate energy and gradually step-down to the stable design streams. 6.6 Vegetation Plan Riparian buffers will be established or preserved a minimum of 50 feet from the top of the streambanks along each of the Project reaches, as well as permanently protecting those buffers with a conservation easement. Many of the proposed riparian buffer widths within the conservation easement are greater than 50 feet along one or both streambanks to provide additional functional uplift potential. Proposed plantings will be conducted using native tree species seedlings. Proposed plantings will consist of bare root vegetation and will be planted at a total target density of 680 stems per acre. This planting Final Mitigation Plan Starker Mitigation Project Page 37 density has proven successful with the reforestation of past mitigation projects, based on current USACE regulatory guidelines requiring 210 trees at Year 7. The proposed plant selection will help to establish an appropriate natural vegetation community based on reference conditions and water quality goals. Schafale's (2012) Natural Communities of North Carolina, as well as existing mature species identified throughout the Project area, were referenced during the development of riparian buffer planting plan for the Project site. The closest approximation natural communities are Piedmont/Low Mountain Alluvial Forest on the narrow stream floodplains and Mixed- Mesic Hardwood Forest (Piedmont Subtype) on adjacent side slopes. Species proposed for revegetation planting are presented in Table 17. Riparian wetlands are generally too small to necessitate a separate community designation. Table 17.

Species substitutions will be coordinated between WLS and planting contractor prior to the procurement of seeding stock. A red -line table will be provided in the As -Built report document. 6.6.1 Planting Materials and Methods Planting will be conducted during the dormant season, with all trees installed between November 15th and March 30t". The final planting zone limits may be modified based on these observations and comparisons, and the final selection of the location of the planted species will be matched according to the species wetness tolerance and the anticipated wetness of the planting area. Final Mitigation Plan Starker Mitigation Project Page 38 Live Staking and Live Branch Cuttings: Where black willow (Salix nigra) and silky willow (Salix sericea) live staking is proposed on streambanks, live stakes will typically be installed at a minimum of 40 stakes per 1,000 square feet and the stakes will be spaced approximately two to three feet apart in meander bends and six to eight feet apart in the riffle sections, using a triangular spacing pattern along the streambanks, between the toe of the streambank and bankfull elevation. When bioengineering is proposed, live branch cutting bundles will be installed at five linear feet per bundle approximately two to three branches thick. Permanent Seeding: Permanent seed mixtures of native species herbaceous vegetation and temporary herbaceous vegetation seed mixtures will be applied to all disturbed areas of the Project site. Temporary and permanent seeding will be conducted simultaneously at all disturbed areas of the Project site during construction and will conducted with mechanical broadcast spreaders. Table 18 lists the proposed species, mixtures, and application rates for permanent seeding. The vegetation species proposed for temporary seeding germinate quickly to swiftly establish vegetative ground cover and thus, short term stability. The permanent seed mixture proposed is suitable for streambank, floodplain, and adjacent riparian wetland areas, and the upland transitional areas in the riparian buffer. Beyond the riparian buffer areas, temporary and permanent seeding will also be conducted at all other disturbed areas of the Project site that are susceptible to erosion. If temporary seeding is applied from November through April, rye grain will be used and applied at a rate of 130 pounds per acre. If applied from May through October, temporary seeding will consist of browntop millet, applied at a rate of 40 pounds per acre. Table 18.

Species substitutions will be coordinated between WLS and planting contractor prior to the procurement of seeding stock. Invasive Species: Invasive exotic species vegetation, such as Chinese privet, Kudzu and multiflora rose will be treated to control their presence, inhibit their spread, and allow planted natural communities to mature. There are some areas with Japanese stilt grass and fescue present, these areas will be monitored to make sure the vegetation does not interfere with native plant growth and establishment of the desired natural community, but are not proposed for treatment throughout the easement. Black walnut species will be removed during construction as much as possible and will be treated post -construction only where threating the success of planted vegetation. Final Mitigation Plan Starker Mitigation Project Page 39 6.7 Site Construction Methods 6.7.1 Site Grading and Construction Elements Much of the grading across the Project site will be conducted within the existing riparian corridor. The restored streams will be excavated within the existing valleys. Suitable fill material will be generated from new channel excavation and adjacent upland areas and hauled to ditch fill/plugs or stockpile locations as necessary. Portions of the existing, unstable channels will be partially to completely filled in along their length using compactable material excavated from construction of the restored channels. Floodplain grading activities will focus on restoring pre -disturbance valley topography by removing field crowns, overburden/spoil, and surface drains that were imposed during conversion of the land for agriculture. In general, floodplain grading activities will be minor, with the primary goal of soil scarification, creating depressional areas, water quality and habitat features, and microtopographic crenulations by filling the drainage features at the Project site back to natural ground elevations (Scherrer, 1999). Any excess material not used for ditch plugging or suitable as a soil base for vegetation will be spread across upland areas outside of the easement boundary and jurisdictional WOTUS. Locations with depressional areas greater than 14 inches deep will be called out on as -built drawings. 6.7.2 Stream, Wetland and Floodplain Improvement Features Stream improvement features such as in -stream structures and bioengineering techniques are proposed for grade control, streambank protection, and improving bedform diversity and habitat. All in -stream structures will be constructed from materials naturally found in the region such as hardwood trees, trunks/logs, brush/branches, and gravel stone materials. Whenever possible, existing substrate material in the abandoned stream channels will be harvested and utilized for the new channel locations. WLS will also incorporate bioengineering practices, when appropriate, that use biodegradable materials and fabrics, uncompacted soils, live plant cuttings, and native species vegetation to stabilize streambanks. Bioengineering treatments will provide initial bank stability that allows for the quick establishment of deep-rooted vegetation along the newly restored streambanks. Additionally, floodplain improvement features such as coarse woody debris (CWD) will be installed. This will mimic features like tree throws, snags, stumps, etc. that are commonly found in natural riparian systems. These floodplain improvement features will be added to provide habitat and serve as water storage and sediment sinks throughout the corridor to improve riparian functions (Dooley, 2003). 6.7.3 Construction Feasibility WLS has field verified that the Project site has adequate, viable construction access, staging, and stockpile areas. Physical constraints or barriers, such as stream crossings, account for only a small percentage of the proposed total stream reach length within the Project boundary. Existing Project site access points and features will be used for future access after the completion of construction. 6.7.4 Future Project Risks and Uncertainties Listed below are identified project risks and uncertainties that have been evaluated in the development of design plans for the site, along with methods that have been/will be used to address these concerns. Final Mitigation Plan Starker Mitigation Project Page 40 Land Use Development: There is potential for increased land development around the site in the future that could lead to additional runoff and changes to watershed hydrology. o Methods to Address: The project area has seen little development in recent years, though development could occur near the site in the foreseeable future. Restoration of the site to reconnect streams to their floodplains will reduce the likelihood of future degradation from watershed changes, as increased flows will spread over a wider floodplain. Grade control (in the form of constructed instream structures and natural bedrock outcrops) present across the restored site decrease the chances of future channel incision. In anticipation of development around the conservation easement, breaks in the easement have been placed in areas in anticipation of future roads and utilities. Easement Encroachment: There is potential for landowner encroachment into the permanent conservation easement. o Methods to Address: WLS has had considerable discussions with the landowner regarding the project requirements and limitations of easement access and is confident that the landowners fully understand and will maintain the easement protections. The landowner has also completed previous DMS restoration projects on other property they own. The easement boundaries will be clearly marked per requirements. Any encroachments that do occur will be remedied by WLS or the long-term steward to remedy any damage and provide any other corrections required by the IRT. The easement will not allow for it to be subdivided if or when the surrounding area is developed. Drought and Floods: There is potential for extreme climatic conditions during the monitoring period of the project. o Methods to Address: WLS will apply adaptive management techniques as necessary to meet the site performance criteria. Such adaptive management may include replanting, channel damage repair, irrigation, or other methods. If adaptive management activities are significant, additional monitoring may be required by the IRT. Beavers: While there was no evidence of beaver activity during recent assessments, there is potential for beavers to affect the site during the monitoring period of the project. o Methods to Address: WLS will take steps to trap and remove beaver if they threaten Project success during the monitoring period. 1-40 Widening: There is some potential for the widening of I-40 along the corridor by the Project which could affect the conservation easement. At the present time there are no plans to widen I-40; however, it could potentially happen sometime in the next 15-30 years. o Methods to Address: WLS set the easement boundaries 25 feet off the current right of way to account for potential widening of the corridor. NCDOT has been notified of the Project and did not provide any guidance for easement set -backs or future encroachment. NCDOT will evaluate potential encroachments if the need arises. 7 Maintenance Plan The Project will be monitored on a regular basis and a physical inspection of the Project will take place at least twice a year throughout the post -construction monitoring period until performance standards are met. These inspections may identify Project components and features that require routine maintenance. Routine maintenance is anticipated in the years following Project construction and may include the following components as described in Table 19. Final Mitigation Plan Starker Mitigation Project Page 41 Table 19. Routine Maintenance Components Stream Routine channel maintenance and repair activities may include modifying in -stream structures to prevent piping, securing loose coir matting, and supplemental installation of live stakes and other target vegetation along the Project reaches. Areas of concentrated stormwater and floodplain flows that intercept the channel may also require maintenance. Vegetation Vegetation will be maintained to ensure the health and vigor of the targeted plant community. Routine vegetation maintenance and repair activities may include supplemental planting, pruning, and fertilizing. Exotic/nuisance invasive plant species will be treated by mechanical and/or chemical methods. Any invasive plant species control requiring herbicide application will be performed in accordance with NCDA rules and regulations. Project Site Project boundaries will be demarcated in the field to ensure clear distinction between the Boundary Project site and adjacent properties. Boundaries may be identified by fence, marker, bollard, post, or other means as allowed by Project conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as needed basis. Stream Crossing The stream crossing(s) within the Project may be maintained only as allowed by the recorded Conservation Easement, deed restrictions, rights of way, or corridor agreements. Beaver Routine maintenance and repair activities caused by beaver activity may include supplemental Management planting, pruning, and dewatering/dam removal. Beaver management will be implemented using accepted trapping and removal methods only within the recorded Conservation Easement. Livestock Exclusion Livestock exclusion fencing will be installed outside the Conservation Easement boundary to Fencing ensure no cattle are allowed within the Project boundary. Routine maintenance of fencing will the responsibility of the landowner. 8 Performance Standards The success criteria for the Project will follow the approved performance standards and monitoring protocols presented in this mitigation plan which have been developed in compliance with the USACE October 2016 Guidance, USACE Stream Mitigation Guidelines (April 2003 and October 2005), and 2008 Compensatory Mitigation Final Rule. Monitoring activities will be conducted for a period of seven years with the final duration dependent upon performance trends toward achieving the Project goals and objectives. Specific success criteria components and evaluation methods are described below. 8.1 Streams Stream Hydrology: 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. Stream Profiles, Vertical Stability, and FloodplainAccess: Stream profiles, as a measure of vertical stability and floodplain access will be evaluated by looking at Bank Height Ratios (BHR). In addition, observed bedforms should be consistent with those observed for channels of the design stream type(s). The BHR Final Mitigation Plan Starker Mitigation Project Page 42 shall not exceed 1.2 along the restored Project stream reaches. This standard only applies to restored reaches of the channel where BHRs were corrected through design and construction. Stream Horizontal Stability: Cross -sections will be used to evaluate horizontal stream stability. There should be little change expected in as -built restoration cross -sections. If measurable changes do occur, they should be evaluated to determine if the changes represent a movement toward a more unstable condition (e.g., downcutting, erosion) or a movement towards increased stability (e.g., settling, vegetation establishment, deposition along the streambanks, 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. The bank height ratio and entrenchment ratio will not change more than 10% from baseline conditions at any riffle cross-section during the monitoring period. Streambed Material Condition and Stability: After construction, there should be minimal change in the particle size distribution of the streambed materials, over time, given the current watershed conditions and anticipated upstream sediment supply. Since the stream substrate and supply is predominantly fine particles (sand), significant changes in particle size distribution and excess channel aggradation are not expected. Jurisdictional Stream Flow: The restored stream systems must be classified as at least intermittent, and intermittent streams must exhibit minimum 30 days of continuous flow for some portion of the year during a year with normal rainfall conditions. Stream flow will be monitored and assessed annually during the monitoring period. Photo Documentation: Photographs should illustrate the Project's vegetation and morphological stability on an annual basis. Cross-section photos should demonstrate no excessive erosion or degradation of the banks. Stream crossing photos should show the crossings stability. Longitudinal photos should indicate the absence of persistent mid -channel bars or vertical incision. Grade control structures should remain stable. Deposition of sediment on the bank side of vane arms is preferable. Maintenance of scour pools on the channel side of vane arms is expected. 8.2 Vegetation Vegetative restoration success for the Project during the intermediate monitoring years will be based on the survival of at least 320 stems per acre at the end of Year 3 of the monitoring period; and at least 260 stems per acre that must average seven feet in height at the end of Year 5 of the monitoring period. The final vegetative restoration success criteria will be achieving a density of no less than 210, stems per acre that must average 10 feet in height in Year 7 of monitoring. To be counted towards success criteria the stems must be 2 year old trees, this includes replanted and volunteer trees also on the planting list. In addition, planted trees in each vegetation plot must average 7 feet in height after MY5 and 10 ft in height at MY7 before close out. 8.3 Invasive Species WLS will treat invasive species vegetation within the project area and provide remedial action on a case by -case basis. Common invasive species vegetation, such as Chinese privet, kudzu, and multiflora rose will be removed to allow native plants to become established within the conservation easement. Invasive species vegetation will be treated by approved mechanical and/or chemical methods. Any control Final Mitigation Plan Starker Mitigation Project Page 43 methods requiring herbicide application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations. If necessary, these removal treatments (i.e., cutting and/or spraying) will continue until the corrective actions demonstrate that the site is trending towards or meeting the standard monitoring requirement. 9 Monitoring Plan In accordance with the approved mitigation plan, the baseline monitoring document and as -built report documenting the mitigation activities will be developed within 60 days of the completion of planting and monitoring device installation at the restored Project. In addition, a period of at least six months will separate the as -built baseline measurements and the first -year monitoring measurements. The baseline monitoring document and as -built monitoring report will include all information required by the USACE Stream Mitigation Guidelines, issued in April 2003 and USACE Guidance for Compensatory Stream and Wetland Mitigation Conducted for Wilmington District dated October 2016. WLS will conduct mitigation performance monitoring based on these methods and will submit annual monitoring reports to IRT by December 315Y of each monitoring year during which required monitoring is conducted. Project success criteria must be met by the final monitoring year prior to project closeout, or monitoring will continue until unmet criteria are successfully met. The following subsections summarize the monitoring methods and linkage between the goals, parameters, and expected functional lift outcomes. Figure 10 illustrates the post -construction monitoring feature types and location. 9.1 Stream Monitoring Hydrologic monitoring will be conducted for all of the Project stream reaches. For reaches that involve a combination of traditional Restoration (Rosgen Priority Level I and II) approaches, geomorphic monitoring methods will be employed to evaluate the effectiveness of the restoration practices. Visual monitoring will be conducted along these reaches as described herein. The monitoring of these Project reaches will utilize the methods described under visual monitoring. 9.1.1 Hydrologic Monitoring The occurrence of four required bankfull events within the monitoring period, along with floodplain access by flood flows, will be documented using pressure transducers and/or photography. The pressure transducers will be installed on the floodplain of the restored channels for monitoring. The pressure transducers will record the flood stage between monitoring site visits and used to determine if a bankfull or significant flow event occurred since the previous site visit. Corresponding photographs will be used to document the occurrence of debris lines and sediment deposition on the floodplain during monitoring site visits. This hydrologic monitoring will help establish that the restoration objectives of restoring floodplain functions and promoting more natural flood processes are being met. 9.1.2 Geomorphic Monitoring Pattern: A planimetric survey will be conducted for the entire length of restored channel immediately after construction to document as -built baseline conditions (Monitoring Year 0). The survey will be tied to a permanent benchmark and measurements will include thalweg, bankfull, and top of banks. The plan view Final Mitigation Plan Starker Mitigation Project Page 44 measurements such as sinuosity, radius of curvature, meander width ratio will be taken on newly constructed meanders during baseline documentation (Monitoring Year 0) only. These measurements will demonstrate that the restored stream channel pattern provides more stable planform and associated features than the old channel, which provide improved aquatic habitat and geomorphic function, as per the restoration objectives. Dimension: Permanent cross -sections will be installed and surveyed at an approximate rate of one cross- section per 20 bankfull widths or an average distance interval (not to exceed 500 LF) of restored stream, with approximately 50 percent cross -sections located at riffles, and 50 percent located at pools. Each cross- section will be monumented on both streambanks to establish the exact transect used and to facilitate repetition each year and easy comparison of year-to-year data. The cross-section surveys will occur in years 0 (as -built), 1, 2, 3, 5, and 7, and will include measurements of bankfull cross -sectional area (Abkf) at low bank height, Bank Height Ratio (BHR) and Entrenchment Ratio (ER). The monitoring survey will include points measured at all breaks in slope, including top of streambanks, bankfull, inner berm, edge of water, and thalweg, if the features are present. There should be minimal change in as -built cross -sections. Stable cross -sections will establish that the restoration goal of creating geomorphically stable stream conditions has been met. If changes do take place, they will be documented in the survey data and evaluated to determine if they represent a movement toward a more unstable condition (e.g., down -cutting or erosion) or a movement toward increased stability (e.g., settling, vegetative changes, deposition along the streambanks, or decrease in width -to -depth ratio). Using the Rosgen Stream Classification System, all monitored cross -sections should fall within the quantitative parameters defined for channels of the design stream type. Given the smaller channel sizes and meander geometry of the proposed steams, bank pin arrays will not be installed unless monitoring results indicate active lateral erosion at cross -sections occurring in meander bends or an increase of greater than 15 percent in cross -sectional area, or when visual monitoring indicates potential bank instability. Reference photo transects will be taken at each permanent cross-section. Lateral photos should not indicate excessive erosion or continuing degradation of the streambanks. Photographs will betaken of both streambanks at each cross-section. A survey tape stretched between the permanent cross-section monuments/pins will be centered in each of the streambank photographs. The water elevation will be shown in the lower edge of the frame, and as much of the streambank as possible will be included in each photo. Photographers should attempt to consistently maintain the same area in each photo over time. Profile: A longitudinal profile will be surveyed for the entire length of restored channel immediately after construction (Monitoring Year 0) to document as -built baseline conditions. The survey will be tied to a permanent benchmark and measurements will include thalweg, water surface, bankfull, and top of low bank. Each of these measurements will be taken at the head of each feature (e.g., riffle, pool) and at the maximum pool depth. The longitudinal profile should show that the bedform features installed are consistent with intended design stream type. The longitudinal profiles will not be taken during subsequent monitoring years unless vertical channel instability has been documented or remedial actions/repairs are deemed necessary. Bank height ratios will be measured along the restored reaches using the results of the longitudinal profile. Final Mitigation Plan Starker Mitigation Project Page 45 9.1.3 Flow Duration Monitoring Jurisdictional Stream Flow Documentation: Monitoring of stream flow will be conducted to demonstrate that the restored stream systems classified as intermittent exhibit surface flow for a minimum of 30 consecutive days throughout some portion of the year during a year with normal rainfall conditions. To determine if rainfall amounts are normal for the given year, precipitation amounts using tallied data obtained from an on -site rain gauge will be used, location on Figure 10. In the event that there is an error in the data the Oxford weather station near Claremont, NC, approximately 3.7 miles North of the Project site, will be used. Data from the station can be obtained from USGS. If a normal year of precipitation does not occur during the first seven years of monitoring, monitoring of flow conditions at the Project site will continue until it documents that the intermittent streams have been flowing during the appropriate times of the year. The proposed monitoring of restored intermittent reaches will include the installation of flow devices (continuous -read pressure transducers) within the thalweg (bottom) of the channel towards the upper one- third portion of the reach. In addition, photographic documentation using a continuous series of remote photos over time may be used to subjectively evaluate and document channel flow conditions throughout the year. More specifically, the longitudinal photos should indicate the presence of flow within the channel to illustrate water levels within the pools and riffles. The photographs will be taken from a height of approximately five feet to ensure that the same locations (and view directions) at the Project site are documented in each monitoring period and will be shown on a plan view map. The devices will be inspected on a quarterly basis to document surface hydrology and provide a basis for evaluating flow response to rainfall events and surface runoff throughout the monitoring period. 9.2 Vegetation Monitoring Vegetation -monitoring quadrants or plots will be installed and monitored for stem density and height (vigor) across the Project. The vegetation monitoring plots shall comprise approximately 2% of the planted portion (approximately 27.7 acres planted) of the Project site with approximately 24 plots established randomly within the planted riparian buffer areas. The sampling may employ quasi -random plot locations which may vary upon approval from IRT. Any random plots should comprise no more than 50% of the total required plots, and the location (GPS coordinates and orientation) will be identified in the monitoring reports. The size and location of individual quadrants will be 100 square meters (i.e., 10m X 10m or 5m X 20M) for woody tree species and may be adjusted based on site conditions after construction activities have been completed. No monitoring quadrants will be established within undisturbed wooded preservation areas, however visual observations will be documented in the annual monitoring reports to describe any changes to the existing vegetation community. Vegetation monitoring will occur in the fall each required monitoring year, prior to the loss of leaves. Mortality will be determined from the difference between the previous year's living, planted seedlings and the current year's living, planted seedlings. Data will be collected at each individual quadrant and will include specific data for monitored stems on diameter, height, species, date planted, and grid location, as well as a collective determination of the survival density within that quadrant. Individual planted seedlings will be marked at planting or monitoring baseline setup so that those stems can be found and identified consistently each successive monitoring year. Volunteer species will be noted and if they are on the approved planting list and meet success criteria standards, they will be counted towards success criteria Final Mitigation Plan Starker Mitigation Project Page 46 after being present for two years. Other species not included on the list may be considered by the IRT on a case -by -case basis. The presence of invasive species vegetation within the monitoring quadrants will also be noted, as will any wildlife effects. At the end of the first full growing season (from baseline/year 0) or after 180 days, species composition, stem density and survival will be evaluated. For each subsequent year, vegetation plots shall be monitored for seven years in years 1, 2, 3, 5 and 7, and visual monitoring in years 4 and 6, or until the final success criteria are achieved. 9.3 Visual Assessment Monitoring WLS will conduct visual assessments in support of mitigation performance monitoring. Visual assessments of all stream reaches will be conducted at least twice per monitoring year with a minimum of five months in between each site visit throughout the monitoring period. Photographs will be used to visually document system performance and any areas of concern related to streambank and bed stability, condition of in - stream structures, channel migration, active headcuts, live stake mortality, impacts from invasive plant species or animal browsing, easement boundary encroachments, cattle exclusion fence damage, and the general condition of pools and riffles. The monitoring activities will document and quantify the visual assessment throughout the monitoring period. A series of photographs over time will be compared to subjectively evaluate channel aggradation (bar formations) or degradation, streambank erosion, successful maturation of riparian vegetation, and effectiveness of sedimentation and erosion control measures. More specifically, the longitudinal profile photos should indicate the absence of developing bars within the channel or excessive increase in channel depth, while lateral photos should not indicate excessive erosion or continuing degradation of the banks. The photographs will be taken from a height of approximately five feet to ensure that the same locations (and view directions) at the Project site are documented in each monitoring period and will be shown on a plan view map. The results of the visual monitoring assessments will be used to support the development of the annual monitoring document that provides the visual assessment metrics.

Maintain average BHRs <_1.2 and ERs >_2.2 and document out of bank and/or significant flow events using pressure transducers or photographs & crest gauges. Increase riffle/pool percentage and pool -to -pool spacing ratios compared to reference reach conditions. Decrease streambank erosion rates comparable to reference condition cross- section, pattern and vertical profile values. Within planted portions of the Project site, a minimum of 320 stems per acre must be present at year three; a minimum of 260 stems per acre must be present at year five; and a minimum of 210 stems per acre must be present at year seven. Create a more natural and higher functioning headwater flow regime and provide aquatic passage. Provide temporary water storage and reduce erosive forces (shear stress) in channel during larger flow events. Provide a more natural stream morphology, energy dissipation and aquatic habitat/refugia. Reduce sedimentation, excessive aggradation, and embeddedness to allow for interstitial flow habitat. Increase woody and herbaceous vegetation will provide channel stability and reduce streambank erosion, runoff rates and exotic species vegetation. The Project will be protected in perpetuity by a recorded conservation easement. The conservation easement will allow for annual monitoring and maintenance of the Project during the monitoring phase. Upon final site approval and project closeout, the Project stewardship will be transferred to an approved long-term stewardship program. WLS has partnered with Unique Places To Save (UP2Save) as the long- term steward for the Project site (See Appendix D for conservation easement and engagement letter). Unique Places To Save Attn: Michael Sisco PO Box 1183 Chapel Hill, NC 27514 803-553-1644 info(@uniqueplacestosave.org Final Mitigation Plan Starker Mitigation Project Page 48 This party shall serve as conservation easement holder and long-term steward for the property and will conduct periodic inspection of the Project to ensure that restrictions required in the conservation easement are upheld. Any endowment funds for the conservation easement and deed restrictions shall be negotiated prior to transfer to the responsible party. Funding will be supplied by the responsible party on a yearly basis until such time and endowments are established. The use of funds from the Endowment Account is governed by NC General Statue GS 113A-232(d) (3). Payments and interest gained by the endowment fund may be used only for stewardship, monitoring, stewardship administration, and land transaction costs, if applicable. The management activities will be conducted in accordance with the terms and conditions of the approved UMBI as agreed to by WLS, USACE, and the IRT. 11 Adaptive Management Plan The Sponsor will conduct post -construction monitoring activities and routine maintenance as needed for the duration of the monitoring period. The Sponsorwill notifythe USACE immediately if monitoring results or visual observations demonstrate that performance standards cannot be achieved. In the event the Project site or a specific component of the Project site fails to achieve the performance standards as specified in the mitigation plan, the sponsor shall notify the IRT and develop a corrective action plan and facilitate remedial actions. The Sponsor is responsible for providing any necessary permits to implement the corrective action plan that describes the extent and nature of the work to be performed. If the USACE determines that the Bank is not meeting performance standards, or the Sponsor is not complying with the terms of the instrument, the USACE may take appropriate actions, including but not limited to: holding credit sales, utilizing financial assurances, and/or terminating the instrument. The site will be monitored on a regular basis and a physical inspection of the site will take place at least twice a year throughout the post -construction monitoring period until performance standards are met. These site inspections may identify site components and features that require routine maintenance. Routine maintenance should be expected most often in the first two years following site construction. 12 Financial Assurances CONFIDENTIAL The Sponsor will provide financial assurances in the form of casualty insurance or a performance bond that is acceptable to the USACE and sufficient to assure successful completion of all mitigation bank activities, reporting and monitoring, and any remedial work required pursuant to the approved Mitigation Plan and/or UMBI. The insurance policy or performance bond will be submitted for review and approval by the USACE. The financial assurance will cover the cost estimates for providing the mitigation bank activities such as site mobilization and construction, annual monitoring, and reporting as outlined in Table 21 and broken out by annual cost below. There will be a financial assurance for the construction phase in the amount of $1,300,000 and that financial assurance will be retired following completion of construction and planting. Then a monitoring financial assurance in the amount of $304,000 will be provided to assure completion of seven years of monitoring and reporting, and any remedial work required during the monitoring period.

Suite 1200 Durham, NC 27701 (919) 732-1300 Michael G. Wood January 3, 2019 INTRODUCTION Ecosystem Planning & Restoration (EPR) is investigating the feasibility of stream and riparian wetland mitigation within the Catawba River Basin. The project site was accessed from Rock Barn Road, Catawba County, NC. Three Oaks Engineering (Three Oaks) has been retained to perform a Hydric Soil & Site Investigation that describes and classifies the soil within the study area to make a determination as to its present and/or past hydric status. The Study Area is a 1.18-acre wetland delineated by EPR that is a lightly wooded pasture adjacent to a UT to Mull Creek. The UT is mostly incised. METHODOLOGY Prior to performing the evaluation, NRCS soil maps and USGS topographic maps were reviewed. The field investigation was performed on October 12, 2018, by Michael G. Wood, LSS. Soils were evaluated via hand -turned soil auger borings. Each boring was classified based on soil characteristics indicating the hydric soil status. Boring locations were located with a GPS Unit with sub -meter accuracy and are shown on the attached figure. Hydric soil status is based upon the NRCS Field Indicators of Hydric Soils in the United States -A Guide for Identifying and Delineating Hydric Soils (Version 8.1, 2017). RESULTS Two (2) soil borings were advanced within the Study Area (Figure 1), both of which had colluvium material from the surrounding uplands that washed in from anthropogenic activities. The amount of colluvium varied from 8-13 inches. The colluvium material in both borings was determined to be hydric. The original soil below the colluvium also was determined to have been hydric. In all cases, hydric soil indicator F3 Depleted Matrix was the best match. F3 Depleted Matrix. A layer that has a depleted matrix with 60 percent or more chroma 2 or less that has a minimum thickness of either: a. 5 cm (2 inches) if the 5 cm starts at a depth of <10 cm (4 inches) from the soil surface, or b. 15 cm (6 inches), starting at a depth of <25 cm (10 inches) from the soil surface. CONCLUSION Borings 1 and 2 are prime candidates for wetland rehabilitation. It is anticipated that through removal of the cattle, raising the stream level, limited soil alterations, and re -vegetation, the hydrology will be restored and allow the wetland to regain its normal functions.

Preliminary Determination ® There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The waters, including wetlands have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. The approximate boundaries of these waters are shown on the enclosed delineation map dated 8/20/2020, submitted via email September 15, 2022. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process, including determining compensatory mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary determination is not an appealable action under the Regulatory Program Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved JD, which is an appealable action, by contacting the Corps district for further instruction. ❑ There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). However, since the waters, including wetlands have not been properly delineated, this preliminary jurisdiction determination may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is merely an effective presumption of CWA/RHA jurisdiction over all of the waters, including wetlands at the project area, which is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters, including wetlands on your project area/property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. B.

Further, an AJD, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to make an official determination whether geographic jurisdiction exists over aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic resources in the review area, the Corps will provide an AJD to accomplish that result, as soon as is practicable. This PJD finds that there "may be" waters of the U.S. and/or that there "may be" navigable waters of the U.S. on the subject review area, and identifies all aquatic features in the review area that could be affected by the proposed activity, based on the following information: SUPPORTING DATA.

McIntyre adam@waterlandsolutions.com Dear Mr. McIntyre: This letter is in regard to your prospectus document dated October 2020, for the proposed WLS Catawba 01 Umbrella Mitigation Bank including the Starker Mitigation Site. The proposal consists of the establishment and operation of a commercial umbrella mitigation bank in the Upper Catawba Watershed, Hydrologic Unit Code (HUC) 03050101 of the Santee River Basin. The Starker mitigation site is a 30.3-acre stream and wetland mitigation site located east of Banner Road, between Conover and Claremont in Catawba County, North Carolina (35.7198, - 81.1742). The Corps determined the prospectus was complete and issued a public notice (P/N # SAW- 2020-01540) on November 9, 2020. The purpose of this notice was to solicit the views of interested State and Federal agencies and other parties either interested in or affected by the proposed work. Attached are the comments received in response to the public notice from the Cherokee Nation. The Corps has considered the information provided in the prospectus document, comments received in response to the public notice and information that was discussed during on -site reviews conducted on September 30, 2020. The meeting minutes for field review are attached and no additional revisions to the meeting minutes were provided by IRT members. We have determined that the proposed umbrella mitigation bank appears to have the potential to restore and enhance aquatic resources within the Upper Catawba Watershed, HUC 03050101 of the Santee River Basin. Therefore, the bank sponsor may proceed with preparation of a draft Umbrella Mitigation Banking Instrument (UMBI). Please address all comments included in the attached memo with your draft UMBI submittal. If you have questions concerning the path forward for the proposed mitigation bank, please do not hesitate to contact me at 828-271-7980 x4234.

Please allow this letter to serve as the Nation's interest in acting as a consulting party to this proposed project. The Nation maintains databases and records of cultural, historic, and pre -historic resources in this area. Our Historic Preservation Office reviewed this project, cross referenced the project's legal description against our information, and found no instances where this project intersects or adjoins such resources. Thus, the Nation does not foresee this project imparting impacts to Cherokee cultural resources at this time. However, the Nation requests that the United States Army Corps of Engineers (USACE) halt all project activities immediately and re -contact our Offices for further consultation if items of cultural significance are discovered during the course of this project. Additionally, the Nation requests that USACE conduct appropriate inquiries with other pertinent Tribal and Historic Preservation Offices regarding historic and prehistoric resources not included in the Nation's databases or records. If you require additional information or have any questions, please contact me at your convenience. Thank you for your time and attention to this matter.

The project site is located in Catawba County, near Claremont, North Carolina. The meeting began at 11:OOam with a general summary of the overall project concepts. After the site overview, attendees toured the project site to review existing conditions and proposed mitigation types, restoration approaches, and design concepts. In general, the project site review notes are presented below in the order they were visited. Grouo started on the south side of Interstate 40 5100 (End of Reach) • Meeting started at the bottom end of 5100 at the crossing. • Discussed how the culvert would be an agricultural culvert. Steve noted that at the permitting stage to make it clear that is an agriculture crossing. • IRT noted a lot of Black Walnut species and to avoid planting that species, and remove existing black walnut as needed (do not avoid). • WLS stated that we were unsure of continuing the project past the crossing, Todd was concerned that if we didn't it might cause stability issues upstream. waterlandsolutions.com 1 7721 Six Forks Rd, Ste 1130, Raleigh, NC 27615 1 919-614-5111 91 WATER & LAND SOLUTIONS • Restoration design approach was thought to be the correct approach for the reach. 5101 • Group walked up to 5101. • Steve/Daniel walked up to the origin point. Origin point was located at the end of the conservation easement for that section. • Discussion on how the elevation of the channel needs to be brought up correctly to connect into 5100 and intermittent stream flow might be affected • Group agreed on the restoration approach. 5100 (Below Interstate-40) • Group drove to the culvert output below Interstate-40 and hiked down the hill to the stream. • Discussed restoration approach and raising the bed to match culvert elevation. Talked about how even with raising the streambed elevation not much aquatic passage would result because of how long the culvert is under the interstate. S200 (above crossing) • Group drove across field to S200 and walked from the crossing up to the culvert under Interstate 40. • Daniel explained that enhancement II was proposed in the section between the culvert and the crossing below. • Group discussion on the amount of sediment that appeared to be moving through the channel as well as the lack of vegetation on the banks which might lead to stability issues. • Discussed that restoration could be proposed in this area if justified in the mitigation plan. • Group walked down the stream below the culvert. Discussion on if restoration approach was used above the crossing then the elevation could be set for the crossing culvert and the entire reach in the design. • Group continued to walk S200 below the crossing. Todd stated that there were some areas that looked okay and others that were not, Erin Davis stated that the vegetation was not ideal. • Group agreed that restoration was the best approach to the section below the crossing. S200 (North of Interstate-40 Group drove to the north side of the project and started on 5200. Walking downstream on S200 group discussed restoration approach and what elevation this section would be brought up too. Todd suggested placing a bmp in areas where run off is coming into the easement if possible. 5100 (North of Interstate-40) • Group drove over to 5100 and started at the wetland area. Erin Davis stated that rehabilitation would be a good approach up until the wood line and then inside the wood line enhancement would be a better approach. • IRT suggested adding a wetland gage now in order to document existing conditions and demonstrate functional lift. • Erin Davis inquired about the target hydroperiod and WLS responded we would follow the current 2016 IRT guidance. waterlandsolutions.com 1 7721 Six Forks Rd, Ste 1130, Raleigh, NC 27615 1 919-614-5111 91 WATER & LAND SOLUTIONS S102 • Walked upstream to 5102. Group looked at origin point. • IRT stated that if the restoration approached was used that WLS would have to show that it was still jurisdictional. S103 • Group had similar concerns about 5103 as they did with 5102. WLS would have to show that it was still a jurisdictional feature after the bed elevation is brought up. Overall Notes • Steve suggested starting the easement about 15-20ft off the ROW of the interstate in case of future expansion. WLS/EPR will coordinate with NCDOT during design phase regarding culvert capacity and extra ROW width. • After seeing above and below the interstate the IRT thought that a restoration approach for the section of S200 south of the interstate would be appropriate if clearly justified in the mitigation plan. • Erin Davis noted that WLS should clearly state what the target community is in the mitigation plan. • Overall the IRT members agreed the project is suitable to provide compensatory mitigation, provided it is properly justified in the mitigation plan. • WLS will provide a "Final Prospectus" and table of adjacent owners for public notice.

Although not required by section 7, many agencies request species lists to start the informal consultation process and begin their fulfillment of the requirements under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). This list, along with other helpful resources, is also available on the U.S. Fish and Wildlife Service (Service) Asheville Field Office's (AFO) website: https://www.fws.gov/raleigh/species/ cntylist/nc counties.html. The AFO website list includes "species of concern" species that could potentially be placed on the federal list of threatened and endangered species in the future. Also available are: Design and Construction Recommendations https://www.fws.gov/asheville/htmis/project review/Recommendations.html Optimal Survey Times for Federally Listed Plants https://www.fws.gov/nc-es/plant/plant survey.html Northern long-eared bat Guidance https://www.fws.gov/asheville/htmis/project review/NLEB in WNC.html Predictive Habitat Model for Aquatic Species https://www.fws.gov/asheville/htmls/Maxent/Maxent.html 08/07/2020 Event Code: 04EN1000-2020-E-01917 New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could require modifications of these lists. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of the species lists should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website or the AFO website (the AFO website dates each county list with the day of the most recent update/change) at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list or by going to the AFO website. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a Biological Evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12 and on our office's website at https://www.fws.gov/asheville/htmis/project review/assessment guidance.html. If a Federal agency (or their non-federal representative) determines, based on the Biological Assessment or Biological Evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species, and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http:// www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF. Though the bald eagle is no longer protected under the Endangered Species Act, please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require additional consultation (see https://www.fws.gov/southeast/our-services/permits/eagles/). Wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenerge /) for minimizing impacts to migratory birds (including bald and golden eagles) and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http: www.fws. gov/migratorybirds/CurrentBirdlssues/Hazards/towers/towers.htm; 08/07/2020 Event Code: 04EN1000-2020-E-01917 3 http://www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdlssues/Hazards/ towers/comtow.html. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

Any person or organization who plans or conducts activities that may result in impacts to migratory birds, eagles, and their habitats should follow appropriate regulations and consider implementing appropriate conservation measures, as described below. 1. The Migratory Birds Treaty Act of 1918. 2. The Bald and Golden Eagle Protection Act of 1940. 3. 50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a) The birds listed below are birds of particular concern either because they occur on the USFWS Birds of Conservation Concern (BCC) list or warrant special attention in your project location. To learn more about the levels of concern for birds on your list and how this list is generated, see the FAQ below. This is not a list of every bird you may find in this location, nor a guarantee that every bird on this list will be found in your project area. To see exact locations of where birders and the general public have sighted birds in and around your project area, visit the E-bird data mapping tool (Tip: enter your location, desired date range and a species on your list). For projects that occur off the Atlantic Coast, additional maps and models detailing the relative occurrence and abundance of bird species on your list are available. Links to additional information about Atlantic Coast birds, and other important information about your migratory bird list, including how to properly interpret and use your migratory bird report, can be found below. For guidance on when to schedule activities or implement avoidance and minimization measures to reduce impacts to migratory birds on your list, click on the PROBABILITY OF PRESENCE SUMMARY at the top of your list to see when these birds are most likely to be present and breeding in your project area. NAME BREEDING SEASON Blue -winged Warbler Uermivora pinus Breeds May 1 to Jun This is a Bird of Conservation Concern (BCC) only in particular Bird Conservation 30 Regions (BCRs) in the continental USA Red-headed Woodpecker Melanerpes erythrocephalus Breeds May 10 to Sep This is a Bird of Conservation Concern (BCC) throughout its range in the 10 continental USA and Alaska. 08/07/2020 Event Code: 04EN1000-2020-E-01917 Probability Of Presence Summary The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report' before using or attempting to interpret this report. Probability of Presence ( 1) Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated? The calculation is done in three steps: The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. Breeding Season( ) Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort (1) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. No Data (—) A week is marked as having no data if there were no survey events for that week. Survey Timeframe 08/07/2020 Event Code: 04EN1000-2020-E-01917 3 Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse. ■ probability of presence breeding season I survey effort — no data SPECIES JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Blue -winged Jill Jill ---- ---- —� - — - -- - — --- Warbler --- --�— — BCC -BCR Red-headed III"""""' �j— — --- Woodpecker -4- +—+— ---- ---- — -- - - - - — BCC Rangewide (CON) Additional information can be found using the following links: • Birds of Conservation Concern http://www.fws.gov/birds/management/managed-species/ birds -of -conservation -concern. php • Measures for avoiding and minimizing impacts to birds http://www.fws.gov/birds/ management/project-assessment-tools-and-guidance conservation-measures.php • Nationwide conservation measures for birds http://www.fws.gov/migratorybirds/pdf/ management/nationwidestandardconservationmeasures.pdf Migratory Birds FAQ Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds. Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures and/or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCQ and other species that may warrant special attention in your project location. 08/07/2020 Event Code: 04EN1000-2020-E-01917 4 The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets . Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). 08/07/2020 Event Code: 04EN1000-2020-E-01917 5 Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Lorin. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page. 08/07/2020 Event Code: 04EN1000-2020-E-01917 Wetlands Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

Suite 140 Cary, NC 27511 RE: Starker Mitigation Bank Site Dear Amy James: The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database indicates that there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also included in this report. If a Federally -listed species is found within the project area or is indicated within a one -mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: httr)s://www.fws.aov/offices/Directory/ListOffices.cfm?statecode=37. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund easement, or Federally -listed species are documented near the project area.

Maynard Road, Suite 140 Cary, North Carolina 27511 Subject: Request for Project Review and Comments Starker Stream Mitigation Site Catawba County, North Carolina. Dear Ms. Bennett, Biologists with the North Carolina Wildlife Resource Commission (NCWRC) received your request to review and comment on any possible concerns regarding Starker Stream Mitigation Site. Biologists with NCWRC have reviewed the provided documents. Comments are provided in accordance with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667e) and North Carolina General Statutes (G.S. 113-131 et seq.). The Starker Stream Mitigation Site is located north of Interstate 40 (I-40) and south of Rock Barn Road, and south of I-40 and east of Banner Road NE near Claremont, Catawba County, North Carolina. The site occurs within an existing agricultural and wooded areas. We have no known records for rare, threatened, or endangered species at the site. Ecosystem Planning & Restoration (EPR) surveyed the site for federal and state endangered Schweinitz's sunflower (Helianthus schweinitzii) in mid -July and found no individuals. The optimal survey period for Schweinitz's sunflower is late August through October. EPR states potential suitable habitat occurs for the federal and state threatened dwarf -flowered heartleaf (Hexastylis naniflora) and surveys will be conducted in spring 2021. We offer the following preliminary recommendations to minimize impacts to aquatic and terrestrial wildlife resources: 1. We recommend surveys for Schweinitz's sunflower are conducted during the optimal survey window of mid -August through October. We suggest EPR contact the U.S. Fish and Wildlife Service (USFWS) at (828) 258-3939. 2. We recommend that riparian buffers are as wide as possible, given site constraints and landowner needs. NCWRC generally recommends a woody buffer of 100 feet on perennial streams to maximize the benefits of buffers, including bank stability, stream shading, treatment of overland runoff, and wildlife habitat. Mailing Address: Habitat Conservation • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 707-0220 • Fax: (919) 707-0028 Page 2 01 September 2020 Starker Stream Mitigation Site Catawba County 3. Due to the decline in bat populations, we recommend leaving snags and mature trees, or if necessary, remove tees outside the maternity roosting season for bats (May 15 — August 15). 4. We recommend the planting list is diverse and consists of species typically found in that natural vegetation community, as described by M.P. Schafale in The Guide to The Natural Communities of North Carolina, Fourth Approximation (https://www.ncnhp.org/references/nhp- publications/fourth-approximation-descri tp ions). 5. We recommend reducing the number of right-of-way easements that fragment the mitigation project. If feasible, we suggest extending the mitigation project along Mull Creek to further increase hydrologic function, restore ecological function in the watershed, and provide a corridor for wildlife. 6. Ensure the culverts provide aquatic life passage during low flows. Stringent sediment and erosion control measures should be implemented. The use of biodegradable and wildlife -friendly sediment and erosion control devices is strongly recommended. Silt fencing, fiber rolls and/or other products should have loose -weave netting that is made of natural fiber materials with movable joints between the vertical and horizontal twines. Silt fencing that has been reinforced with plastic or metal mesh should be avoided as it impedes the movement of terrestrial wildlife species. Excessive silt and sediment loads can have detrimental effects on aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills. Thank you for the opportunity to provide comments. We will provide additional comments during the site visit.

We submit the following comments in accordance with the provisions of the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e); the National Environmental Policy Act (42 U.S.C. §4321 et seq.); and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). Project Description According to the information provided, the proposed project involves restoration and enhancement of two unnamed tributaries which connect with Mull Creek River in Claremont, North Carolina. Design plans and descriptions of proposed impact minimization measures were not provided in your correspondence. Onsite habitats (instream and riparian) are highly disturbed due to a legacy of agricultural land use. Surrounding land cover is dominated by forest, agricultural and residential developments. Federally Listed Endangered and Threatened Species Suitable summer roosting habitat may be present in the project area for the northern long-eared bat (Myotis septentriona/is). However, the final 4(d) rule (effective as of February 16, 2016), exempts incidental take of northern long-eared bat associated with activities that occur greater than 0.25 miles from a known hibernation site, and greater than 150 feet from a known, occupied maternity roost during the pup season (June 1 — July 31). Based on the information provided, the project (which may or may not require tree clearing) would occur at a location where any incidental take that may result from associated activities is exempt under the 4(d) rule. Although not required, we encourage you to avoid any associated tree clearing activities during this animal's maternity roosting season from May 15 — August 15. Service records indicate several known occurrences of the federally threatened dwarf -flowered heartleaf (Hexasty/is nanif/ora) in the project vicinity. Moreover, your correspondence indicates that suitable habitat is present onsite for dwarf -flowered heartleaf and the federally endangered Schweinitz's sunflower (Helianthus schweinitzii). Your correspondence states that "the area was searched for specimens in mid -July 2020", but it is unclear if targeted surveys were completed at that time. To ensure that these species are not inadvertently lost, targeted surveys should be conducted by qualified biologists during optimal survey windows where project -mediated impacts overlap their suitable habitats. Surveys are not required where suitable habitats are not present within the proposed impact area. Members of the genus Hexastylis may be identified by characteristic evergreen leaves present throughout the year, but flowers are required to diagnose H. naniflora. The flowering window for this species is typically March — May in North Carolina. The optimal survey window for Schweinitz's sunflower is late -August — October. To complete our evaluation, we request that the Applicant provide this office with survey results and/or provide information indicating that suitable habitats are not present within the proposed impact area for federally protected species. In accordance with the Act, it is the responsibility of the appropriate federal agency or its designated representative to review its activities or programs and to identify any such activities or programs that may affect endangered or threatened species or their habitats. If it is determined that the proposed activity may adversely affect any species federally listed as endangered or threatened, formal consultation with this office must be initiated. We offer the following comments in the interest of protecting this species and other natural resources: Erosion and Sediment Control Measures to control sediment and erosion should be installed before any ground -disturbing activities occur. Grading and backfilling should be minimized, and existing native vegetation should be retained (if possible) to maintain riparian cover for fish and wildlife. Disturbed areas should be revegetated with native grass and tree species as soon as the project is completed. Ground disturbance should be limited to what will be stabilized quickly, preferably by the end of the workday. Natural fiber matting (coir) should be used for erosion control as synthetic netting can trap animals and persist in the environment beyond its intended purpose. Stream Channel and Bank Restoration A natural, stable stream system is one that is able to transport a wide range of flows and associated sediment bed load while maintaining channel features and neither degrading nor aggrading. Alterations to the dimension, pattern, or profile of the stream channel as well as changes to streambank vegetation, floodplains, hydrology, or sediment input can significantly alter this equilibrium. We offer the following recommendations for the Applicant's consideration: Streambanks with deep-rooted woody vegetation are the most stable, and stream restoration efforts should incorporate the use of native vegetation adapted to the site conditions. Live dormant stakes may be used to reestablish root structure in riparian areas. In areas where banks are severely undercut, high, and steep, whole -tree revetment or rock may be used as a stabilization treatment (small rock, gravel, sand, and dirt are not recommended due to their erosive nature), and it should not extend above the bank -full elevation (the elevation of the channel where the natural floodplain begins). Deep -rooting woody vegetation should be established along banks where any channel work is accomplished. Tree and shrub plantings should be spaced at intervals no greater than 10 feet along banks. Vegetated riparian zone widths should be as wide as practical but should extend at least 30 feet from the stream channel. 2. Only the absolute minimum amount of work should be done within stream channels to accomplish necessary reconstruction. Restoration plans should account for the constraints of the site and the opportunities to improve stream pattern, dimension, and profile with minimal disturbance. Reconstruction work should follow natural channel design methodologies that are based on the bank -full, or channel -forming, stage of the stream. Bank -full stage maintains the natural channel dimensions and transports the bulk of sediment over time. Natural channel conditions should be identified using a reference reach (nearby stream reaches that exemplify restoration goals). Restoration design should match the pattern, dimension, and profile of the reference reach to ensure the project's success. 4. All work in or adjacent to stream waters should be conducted in a dry work area to the extent possible. Sandbags, cofferdams, bladder dams, or other diversion structures should be used to prevent excavation in flowing water. These diversion structures should be removed as soon as the work area is stable. Equipment should not be operated in the stream unless absolutely necessary. Machinery should be operated from the banks in a fashion that minimizes disturbance to woody vegetation. Equipment should be: (a) washed to remove any contaminant residue prior to project construction, (b) in good working order, and (c) checked to ensure there are no leaks of potential contaminants (such as oil or other lubricants) prior to and during construction. 6. Adequate measures to control sediment and erosion must be implemented prior to any ground -disturbing activities in order to minimize effects on downstream aquatic resources. In North Carolina, non -cohesive and erosion -prone soils are most common in the felsic-crystalline terrains of the mountain and upper piedmont regions. Therefore, reconstruction work should be staged such that disturbed areas would be stabilized with seeding, mulch, and/or biodegradable (coir) erosion -control matting prior to the end of each workday. Matting should be secured in place with staples; stakes; or, wherever possible, live stakes of native trees. If rain is expected prior to temporary seed establishment, additional measures should be implemented to protect water quality along slopes and overburden stockpiles (for example, stockpiles may be covered with plastic or other geotextile material and surrounded with silt fencing). The Service appreciates the opportunity to provide these comments. Please contact Mr. Byron Hamstead of our staff at Byron_Hamstead@fws.gov, if you have any questions.

Onsite habitats (instream and riparian) are highly disturbed due to a legacy of agricultural land use. Surrounding land cover is dominated by forested areas, agricultural and residential developments. Federally Listed Endangered and Threatened Species Suitable summer roosting habitat may be present in the project area for the federally threatened northern long-eared bat (Myotis septentrionalis), and Service records indicate multiple mist -net captures of this animal in the project vicinity. However, the final 4(d) rule (effective as of February 16, 2016), exempts incidental take of northern long-eared bat associated with activities that occur greater than 0.25 miles from a known hibernation site, and greater than 150 feet from a known, occupied maternity roost during the pup season (June 1 — July 31). Based on the information provided, the project would occur at a location where any incidental take that may result from associated activities is exempt under the 4(d) rule. Although not required, we encourage you to conduct tree removal activities outside of the northern long-eared bat pup season (June 1 to July 31) and/or the active season (April 1 to October 15). This will minimize impacts to pups at roosts not yet identified. Service records indicate several known occurrences of the federally threatened dwarf -flowered heartleaf (Hexastylis naniora) in the project vicinity. Moreover, your correspondence indicates that suitable habitat is present onsite for dwarf -flowered heartleaf and the federally endangered Schweinitz's sunflower (Helianthus schweinitzii). However, botanical surveys conducted during September 30, 2020 and April 15, 2021 detected no evidence for these species at that time. Due to the presence of suitable habitat, but lack of onsite evidence for these species, we believe the probability for project -mediated loss is insignificant and discountable. Therefore, we would concur with a "may affect, not likely to adversely affect" determination for these species from the applicable federal action agency. Please be aware that obligations under section 7 of the Endangered Species Act must be reconsidered if: (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered, (2) this action is subsequently modified in a manner that was not considered in this review, or (3) a new species is listed or critical habitat is determined that may be affected by the identified action. We offer the following general recommendations on behalf of natural resources: Erosion and Sediment Control Construction activities near aquatic resources, streams, and wetlands have the potential to cause bank destabilization, water pollution, and water quality degradation if measures to control site runoff are not properly installed and maintained. In order to effectively reduce erosion and sedimentation impacts, best management practices specific to the extent and type of construction should be designed and installed prior to land disturbing activities and should be maintained throughout construction. Natural fiber matting (coir) should be used for erosion control as synthetic netting can trap animals and persists in the environment beyond its intended purpose. Land disturbance should be limited to what can be stabilized quickly, preferably by the end of the workday. Once construction is complete, disturbed areas should be revegetated with native riparian grass and tree species as soon as possible. For maximum benefits to water quality and bank stabilization, riparian areas should be forested; however, if the areas are maintained in grass, they should not be mowed. The Service can provide information on potential sources of plant material upon request. A complete design manual that is consistent with the requirements of the North Carolina Sedimentation and Pollution Control Act and Administrative Rules, can be found at the following website: https://deq.nc.gov/about/divisions/energy-mineral-land-resources.
