Send all suspicious email as an attachment to report.spam@nc.gov Bryan - Attached are the items that you requested for the Albemarle Corporate Center permit application. These include: 1) Pond Drainage Plans for Ponds PE and PF 2) A Preliminary Stream and Riparian Area Restoration Plan, which includes information for the items listed in your original email 3) An ORM Upload Sheet for all features associated with the project As stated in the PCN, we had not completed the Schweinitz's sunflower surveys for the project. Those surveys have since been completed and I have also attached the survey memo outlining the results of the survey and the Biological Conclusion for the species. Additionally, based on comments from NCDWR, Chambers realized that the 10-foot countersunk rip -rap pad at three sites had not been accounted for in the original plans. Therefore, I have also included an updated set of Permit Drawings (file named "Environmental Impacts 9.28.20-compressed") and a comparison of Stream Impact Changes between the PCN and the updated drawings. These changes are also reflected in the Roadway Plans and Grading and Erosion Control Plan, which I will also send to you shortly in a separate email (due to file size). All three sets of drawings also incorporate changes requested by NCDWR. I will be responding to Alan in a separate email identifying what changes were made based on his requests and will cc you on that email. Please let me know if you have any questions or require any additional information.

Second Street Albemarle, NC 28001 SUBJECT: Schweinitz's Sunflower (Helianthus schweinitzh) Survey Report for Proposed Albemarle Corporate Center Project Site (Stanly County, North Carolina) Dear Mr. Ferris: Three Oaks Engineering, Inc. (Three Oaks) was retained by Chambers Engineering, PA to conduct a protected species survey for the federally -endangered Schweinitz's sunflower (Helianthus schweinitzii) within a 282-acre project study area located immediately west of Groves Avenue and east of South Business 52 in Albemarle, N.C. (Parcel PIN Nos. 654702867363 and 654804904100 [partial]). An additional 11-acre portion of the project area along the proposed sewer line extension was previously assessed in 2019 and determined to have no habitat for this species and, therefore, did not require surveys (Appendix A; Figure 1). This memo presents the findings of this plant survey, which was conducted on August 20, 2020. The survey was led by Three Oaks Senior Environmental Scientist Mary Frazer. Qualifications for personnel who performed the surveys are as follows: Lead Investigator: Mary Frazer Education: M.E.M. Resource Ecology, Duke University B.S. Zoology, University of Wisconsin Experience: Senior Environmental Scientist, Three Oaks Engineering, July 2015-present Environmental Program Consultant, NCDOT, 2000-2015 Environmental Specialist, Wisconsin Coastal Management Program, 1996-2000 Water Regulation Specialist, Wisconsin Department of Natural Resources, 1994-1996 Biologist, Soil and Environmental Consultants, 1992-1994 Experience Surveying for Subject Species: Twenty years of experience surveying for Schweinitz's sunflower, initially working for the NC Department of Transportation, conducting surveys for highway construction and bridge replacement projects. Conducted surveys, mitigation work and monitoring for Schweinitz's sunflower for the Charlotte outer loop construction (R-2248E) & I-485/I-85 interchange modifications (R- 2123) in Mecklenburg County. Conducted surveys, mitigation work and monitoring for Schweinitz's sunflower for Surratt Road improvements in Davidson County, Caraway Mountain Road in Randolph County and Orrell Road in Stokes County. Three Oaks Engineering threeoaksengineering.com • Conducted regular monitoring of 90 Schweinitz's sunflower populations in NCDOT rights - of -way. • As a Three Oaks staff member, continued to perform Schweinitz's sunflower surveys on NCDOT, municipal, and private projects, such as NC 24-24 Improvements (R-2303B) in Stanly County. Investigator: Nathan Howell Education: B.S. Fisheries, Wildlife and Conservation Biology, North Carolina State University, 2013 M.S. Plant and Microbial Biology, North Carolina State University, 2015 Experience: Three Oaks Engineering, October 2015 — Present Experience Surveying for Subject Species: As a Three Oaks staff member, Nathan has approximately 5 years of experience surveying for Schweinitz's sunflower. Schweinitz's Sunflower Morphology and Habitat Description (via U.S Fish and Wildlife Service [USFWSI: https://ecos.fws.2ov/ecpO/profile/speciesProfile?sId=3849 ) Morphology: Schweinitz's sunflower is a perennial that grows approximately 6.5 feet (ft) (2.0 meters; m) tall (though it can be shorter if young or injured) and can occasionally reach heights of 16 ft (4.8 m). It has thickened roots that are used by the plant to store starch. The stem is purplish in color, and the upper third bears secondary branches at 45-degree angles. The leaves are arranged in pairs on the lower part of the stem but usually occur singly (or alternate) on the upper parts. Leaves are attached to the stem at right angles, and the tips of the leaves tend to droop. The leaves are thick and stiff, have a rough upper surface with broad spiny hairs that are directed toward the tip and soft white hairs that cover the underside. The plant produces small yellow flowers from late August until frost. This species is able to colonize through the dispersal of seeds that readily germinate without a dormant period. The optimal survey window for this species is late August — October. Habitat Description: Schweinitz's sunflower occurs in full to partial sun and is found in areas with poor soils, such as thin clays that vary from wet to dry. It is believed that this species once occurred in natural forest openings or grasslands. Many of the remaining populations occur along roadsides. Survey Results The survey for this project occurred slightly prior to the optimal survey window for the target species. Therefore, Three Oaks' staff members visited an extant Schweinitz's sunflower reference population (N.C. Natural Heritage Program [NCNHP] Element Occurrence No. 182 [EO ID 22996]) prior to the survey. This reference population is located at the intersection of South Business 52 and Stony Gap Road in Albemarle, North Carolina. Schweinitz's sunflower individuals at the reference site were budding, and several were just beginning to flower. Photographs of the reference site are located in Appendix B. Suitable habitat for Schweinitz's sunflower exists within the study area. The best habitat is located along sunny, dry, clayey field/woodland interfaces, road edges, canopy gaps in forested areas, and early successional openings that experience periodic mowing. On August 20, 2020 Three Oaks staff members conducted a survey for this species. Particular attention was paid to the previously mentioned best habitats (Appendix A; Figure 1). Larger early - successional openings were transected to ensure a thorough review. Schweinitz's sunflower was not detected within the study area. One colony of spreading sunflower (Helianthus divaricatus) was found within a sunlit oak opening on a ridge. Early successional species dominated the fallow fields and brushy openings within the property. Species occurring within these habitats include horseweed (Erigeron bonariensis), goldenrod (Solidago sp.), dogfennel Three Oaks Engineering threeoaksengineering.com ---------------------- ------ --------- --- -- -------------- ------- ---------------- ------ 0 (Eupatorium capillifolium), pokeweed (Phytolacca americana), eastern blackberry (Rubus pennsylvanicus), Chinese lespedeza (Lespedeza cuneata), and various grass species. Photographs of the site are in Appendix C. The NCNHP July 2020 dataset indicates no known Schweinitz's sunflower occurrences within the study area. However, two extant populations (EO Nos. 182 and 117) are located within one mile of the study area. These two populations are located at the intersections of South Business 52 and Stony Gap Road, and South Business 52 and US Hwy 52. Due to the presence of known populations within a mile of the study area and negative survey results, , a Biological Conclusion of "May Affect — Not Likely to Adversely Affect " has been rendered for Schweinitz's sunflower. This determination will require concurrence from the US Fish and Wildlife Service. Please let me know if you have any questions or require any additional information.

Pond PE Dam Pond PE from East side Pond PE dam looking downstream towards creek Pond PF from road between ponds PE and PF Road/dam between ponds PE and PF Preliminary Stream and Riparian Area Restoration Plan Albemarle Corporate Center Albemarle, North Carolina Introduction The City of Albemarle (“City”) is proposing to construct the Albemarle Corporate Center in Albemarle, North Carolina. The proposed development is a business park including up to 16 separate buildings totaling up to 1,688,750 square feet of enclosed building space. As part of the site proposal, a road network will also be constructed that connects the corporate center to US 52 Business, Leonard Avenue, and Henson Street. Utilities such as gravity sewer, water, and electricity are also proposed for the site. As part of the Albemarle Corporate Center project, the drainage of two existing in-line jurisdictional ponds along Poplin Branch (Ponds PE and PF) is proposed, restoring Poplin Branch to a natural free-flow state (Site 15 in the Pre-Construction Notification [PCN]). The ponds currently constitute 1.13 acres of open water (0.60 ac. for Pond PE, 0.53 ac. for Pond PF); by draining them, a significant portion of Poplin Branch will be effectively daylighted, allowing for the reformation of up to 733 linear feet of 2nd order stream, along with abutting riparian floodplain, riparian buffer, and potential floodplain wetlands. Below is the Preliminary Stream and Riparian Area Restoration developed for the project. Since the ponds have not yet been drained, the site conditions of the pond beds and former channel are currently unknown. It is, therefore, not possible to develop a Final Restoration Plan for the site at this point in time. The approach for this project is to drain the ponds following the Pond Drainage Plan, with the expectation that all or part of the following Restoration Plan can be followed. However, a site visit will be requested with City, U.S. Army Corps of Engineers (USACE) and N.C. Division of Water Resources (NCDWR) officials and Chambers Engineering, PA (Chambers) and Three Oaks Engineering, Inc (Three Oaks) staff to review the site post-drainage. This will allow regulatory agencies to view the site conditions after the ponds are drained, offer input on the Preliminary Restoration Plan, and assist in the development of the Final Stream and Riparian Area Restoration Plan. Restoration Goals The restoration goals for the Albemarle Corporate Center are to remove the existing earthen dams and drain existing Ponds PE and PF, restoring Poplin Branch to a natural free-flow state. Additionally, removing the ponds will re-connect aquatic habitat between the upstream and downstream reaches of Poplin Branch, allowing riverine aquatic species to again have unobstructed passage throughout the stream reach. It will also provide additional wildlife habitat within the newly restored riparian areas. The ponds will be drained following the included Pond Drainage Plan, which has been developed to safely and slowly drain both ponds, while avoiding/minimizing the release and migration of accreted sediment within the ponds downstream of the drainage sites. Prior to draining the ponds, it is difficult to know the status of the former channel or the extent sediment and debris accumulation. Therefore, the initial approach will be, after the ponds are drained and any large deposits of unconsolidated sediments that are prone to erosion removed, to breach the earthen dam downstream of Pond PE and allow Poplin Branch to begin to naturally reform and re-channelize, establishing a natural stream flow pattern through the drained areas. This approach will allow the stream to follow a similar flow pattern as prior to being dammed. Where and 2 when needed, the stream channel and banks will be stabilized, with methods such as coir fiber matting, rip rap bank stabi- lization, and live staking. Substrate composition within the thalweg will be monitored to determine if active natural sub- strate sorting is occurring along the stream reach and if any additional measures are required to assist the streambed’s reestablishment. After the ponds have been drained and Poplin Branch has begun to naturally find its path and hydrological function (includ- ing dynamic channel processes) has started to be restored, any additional accumulated “unnatural” sediment will be re- moved from the exposed areas outside of the streambanks and the area will be graded to an appropriate elevation and contour to match the upstream and downstream reaches surrounding the formerly-ponded areas. The final grading ap- proach will not be determined until after the ponds have been drained and the agency site visit has occurred. The graded areas will initially be stabilized with a native riparian plant seed mix (herbaceous species). The restoration will also rely on the expected migration of Facultative to Obligate species present in adjacent areas (depending on the ultimate hydrology of the exposed area) establishing themselves within the exposed pond beds and capturing the newly available habitat. Once the streamside areas are initially stabilized, the seeded areas outside of the streambanks will then be planted with appropriate floodplain woody species. Stem count and planting density will ultimately be determined once it is clear how much of the area will be viable floodplain/riparian buffer. Species composition has been developed to match existing riparian conditions upstream and downstream of the site as much as possible. Post-restoration monitoring will be performed that will primarily include stream and streambank monitoring, planting suc- cess monitoring, and monitoring for the establishment of floodplain wetlands. Ultimately, the area to be restored will be protected ad-infinitum via a deed restriction, easement, or other site protection instrument.

Grading Plan The grading strategy is to establish continuity between the drained area and the upstream and downstream riparian areas and floodplains, with the goal of matching the elevation, contours, and slope with the surrounding areas. Removal of ac- creted sediment from the drained area is also planned, to return the area to natural conditions; this will occur prior to grading and plans for its removal and proper disposal will be included in the Final Stream and Riparian Area Restoration Plan. If required, grubbing of old tree stumps and removal of accumulated debris will also occur. If required, streambank grading to a more stable slope will also be considered to further stabilize the establishing banks/ portions of banks and facilitate floodplain access. At this point in time, it is unknown what the ultimate strategy will be to accomplish these goals due to the uncertainty of the site conditions under the filled ponds. Therefore, specific details related to the grading of the drained areas will be developed for the Final Restoration Plan once site conditions are known. Stabilization Plan Due to the unknown conditions currently within the ponded areas, it is difficult to ascertain the condition of the pond beds and the former channel. This complicates preliminarily design and implementing any natural stream design at this phase of the project. Therefore, the project approach is to allow for Poplin Branch to begin to establish its natural channel to use as the basis for the Final Stream and Riparian Area Restoration Plan. Channel establishment will be monitored starting with the draining phase of the project and continue throughout the restoration process until the stream channel is deemed stabilized by USACE and NCDWR. Intervention techniques will be determined in the field, if necessary, and may include: 3 1) Sediment removal from channel 2) Armoring of portions of stream bank with rip rap 3) Stabilizing stream bank with coir fiber matting 4) Laying back the slope of portions of the stream bank to minimize erosion 5) Live staking (if required, on no closer than 3-foot centers; would be done concurrent with other woody plantings) Any/all of the above techniques will be approved by USACE and NCDWR, if required, and incorporated into the Final Resto- ration Plan, along with any cross sections and/or plan details related to the stabilization strategy. The goal will be to establish successful channel stability, survival of live-staked vegetation (if required), and lack of significant bank erosion, channel widening, or down-cutting. Planting Plan It will be difficult to determine the amount of area available for replanting until the area is drained and the stream has begun to re-establish itself; therefore, the area and exact number of re-plantings cannot be determined at this point. How- ever, a general strategy of how to replant has been developed that includes the initial re-seeding of the riparian area with a native riparian plant seed mix (herbaceous species) to provide early stabilization, followed by planting of native riparian woody species (rooted stock; saplings or cuttings) to provide further stability. General planting density and species to be planted are outlined below and will include native species similar to those present in the surrounding riparian areas. Mon- itoring of plantings for up to 5 years and calculating survival based on plants/acre each year will be the primary measure of planting success (which will be approved by USACE and NCDWR). A secondary measure will be the amount of surrounding native species that migrate into the drained area. Initial re-seeding post-dam removal After the ponds have been dewatered, accreted sediment has been removed, and riparian areas have been graded to match existing upstream and downstream contours and elevation, the new riparian areas will be initially re-seeded with a native riparian plant seed mix comprised of native herbaceous species that are at least Facultative in growth habit. The amount of area available for replanting will not be known until the pond areas are drained. Seeding with occur during the appropriate window just prior to or during the growing season. Seeding technique will depend on the site conditions but may include hand seeding, broadcast seeding, a combination of both, or another site-appropriate technique. The use of bioengineering material, such as coir fiber matting, will depend on site conditions at the time of seeding. A pH-appropriate organic material (i.e. mulch, compost, leaf litter, pine straw, etc.) will be overlain on the seeded areas; no fertilizers or soil enrichment such as lime will be used so as to prevent water contamination. This seeding will provide initial vegetative stabilization while the area is still re-establishing itself and will provide some habitat for native wildlife. If areas exhibit erosion and require addi- tional stabilization while the herbaceous vegetation is establishing itself, those areas will be specifically addressed with additional stabilization techniques, including bioengineering materials. Also, if re-seeding is required in any areas, it will be done during the appropriate time of growing season. Seeding of herbaceous plants will be the effective start of plant mon- itoring Year 1. Planting of woody species Once the herbaceous vegetation has established itself and the riparian areas are stabilized, native woody rooted stock will be planted in the form of saplings or cuttings. Species that are planted will be similar to those within the floodplain upstream 4 and downstream of the pond drainage, but species composition will be based on sapling/cutting availability. Species may include, but are not limited to: 1) Red maple (Acer rubrum) 2) Sweetgum (Liquidambar styraciflua) 3) Tag alder (Alnus serrulata) 4) Sycamore (Platanus occidentalis) 5) Red elm (Ulmus rubra) 6) Green ash (Fraxinus pennsylvanica) 7) Tulip poplar (Liriodendron tulipifera) 8) Box elder (Acer negundo) Saplings will be planted at approximately 6- to 10-foot centers, random spacing, averaging 8-foot centers to allow for an- ticipated branch and canopy growth. This planting pattern equates to roughly 680 planting/acre; however, ultimate density will be based on available riparian area post-drainage. Sapling planting techniques, such as the Dibble Planting Method, will be determined based on site conditions at the time of planting. If live staking of the stream banks is required, it will be done concurrently with the riparian area planting. Saplings/cuttings will be placed, on average, on 3-foot centers on the banks and will include species such as black willow (Salix nigra) and silky dogwood (Cornus amomum). The species list for re-planting of the riparian area and stream banks will be provided to USACE and NCDWR prior to planting for approval. Assessment for migration of native species from adjacent areas A general assessment of the riparian areas will occur annually for up to 5 years to determine whether native species from adjacent areas have migrated and established themselves. This assessment will occur concurrent with any other plant mon- itoring efforts. A species inventory will be compiled each year of monitoring to track what new species have successfully migrated into the area. Plant monitoring plan and success The planted riparian areas will be monitored annually for up to 5 years (or other earlier predetermined end to the monitor- ing plan), beginning with the seeding of herbaceous plants effectively starting Year 1. Success of woody and herbaceous planting will be assessed annually. Success for vegetation monitoring within the riparian area will depend on agency input and approval; based on other similar projects, an example success measure for woody species is the survival of at least 260 stems per acre of 5-year-old trees/saplings at year 5. Success of herbaceous vegetation will be assessed based on the stabilization of the area and overall coverage of herbaceous plants compared to reference areas upstream and downstream of the restored area. A general assessment of the area to determine whether native species from surrounding areas have migrated into the area will also be conducted annually; success of this component will be measured on whether these species have successfully established themselves in at least a portion of the new area at year 5. 5 Monitoring Plan Site monitoring will consist of the following phases: 1) Pond drainage monitoring 2) Monitoring of sediment removal and grading 3) Monitoring of channel stability 4) Plant monitoring 5) Monitoring of wetland development Pond drainage monitoring This monitoring will follow the monitoring plan outlined in the Pond Drainage Plan. The goal is to minimize the release and migration of accreted sediment within the ponds downstream of the drainage sites. The pre-drainage conditions of the reach of Poplin Branch downstream of the ponds will be photo-documented so that a pre- and post-drainage comparison can be completed to determine whether the Pond Drainage Plan was successful. The drainage site and the downstream reach will be monitored during and after pond drainage and will be photo-documented to identify any complications related to the pond release. If at any time during the drainage an issue related to sediment release downstream or erosion related to the release, drainage will be halted until the issue is rectified. As-builts will be provided in the Final Stream and Riparian Area Restoration Plan once the ponds have been drained and graded. Please see the Pond Drainage Plan for more details. Monitoring of sediment removal and grading After the ponds have been drained, the downstream earthen dam breached, and Poplin Branch has begun to naturally find its path and restore its hydrological function, accumulated sediment will be removed from the exposed areas outside of the streambanks and the area will be graded to an appropriate elevation and contour to match the upstream and downstream reaches surrounding the formerly-ponded areas. The area will be photo-documented, along with the upstream and down- stream reaches, to monitor grading success. Monitoring will consist of confirming proper disposal of removed sediment, confirmation that no sediment is being released into the stream during either removal or grading operations, and confirm- ing that the contours and elevation of the site match upstream and downstream reaches via surveying before moving on to the planting phase. Monitoring of channel stability Monitoring of this phase will begin at the drainage phase of the project and will continue up to 5 years afterwards, or when the stream channel is deemed stabilized by USACE and NCDWR. The goal is to allow Poplin Branch to re-establish itself within the drained area to re-connect to both the upstream and downstream reaches surrounding the ponds. As monitoring begins, it is recognized that problem areas may occur. In such instances, a plan will be developed to address these areas which may include techniques outlined in the Stabilization Plan section above. Any/all of the above techniques will be approved by USACE and NCDWR, if required. Assessment of channel stability will be based on successful channel stability, survival of live-staked vegetation (if required), and lack of significant bank erosion, channel widening, or down-cutting. 6 Plant monitoring Plant monitoring will follow the Planting Plan described above, which states: The planted riparian areas will be monitored annually for up to 5 years (or other earlier predetermined end to the monitor- ing plan), beginning with the seeding of herbaceous plants effectively starting Year 1. Success of woody and herbaceous planting will be assessed annually. Success for vegetation monitoring within the riparian area will depend on agency input and approval; based on other similar projects, an example success measure for woody species is the survival of at least 260 stems per acre of 5-year-old trees at year 5. Success of herbaceous vegetation will be assessed based on the stabilization of the area and overall coverage of herbaceous plants compared to reference areas upstream and downstream of the re-stored area. A general assessment of the area to determine whether native species from surrounding areas have migrated into the area will also be conducted annually; success of this component will be measured on whether these species have successfully established themselves in at least a portion of the new area at year 5. Monitoring for wetland development It is possible that jurisdictional floodplain wetlands will naturally develop along the restored portion of Poplin Branch, similar to the existing wetlands along other portions of the creek and its tributaries. Assessment for potential wetlands will occur annually, concurrent with plant and stream monitoring efforts, to determine whether wetland development is occur- ring/has occurred. Methodology outlined in the USACE Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont Region (Version 2.0) will be followed. Areas that show outward wetland hydro- logical and hydrophytic vegetation indicators will be further assessed to determine soil composition. If an area meets all three wetland criteria, it will be delineated, and its boundaries located via GPS. This assessment will occur annually for up to 5 years. Any wetlands that develop will be re-assessed each year to see if their boundaries have changed and the remain- ing areas will be re-assessed for potential wetland development. At the end of the monitoring period, a final delineation will occur, and proper wetland and upland forms will be completed. USACE will then be requested to visit the site and verify any wetlands that have developed over that time frame. Acquisition of a Site Protection Instrument A form of site protection instrument, such as a deed restriction or easement, will be pursued to protect the final restored site once it is clear what the likely boundaries of will be in the future. The method of protection will be proposed to and approved by NCDWR and USACE. Success Criteria The success of the project’s stream and riparian area restoration effort will be measured by the following criteria: 1) Successful pond drainage 2) Re-establishment and stabilization of pond-drained portion of Poplin Branch 3) Grading of riparian areas exposed by pond drainage 4) Planting of riparian areas 5) Establishment of floodplain wetlands 6) Establishment of a site protection instrument Several of these success measures cannot be specifically determined until after the ponds are drained. However, a general outline of what would be considered a successful stream and riparian area restoration after pond drainage can be provided. 7 Below is a description of the parameters that will be reviewed for each of the above-listed items to determine if the project is a success. Successful Pond Drainage Success of pond drainage will be measured based on whether the proposed Pond Drainage Plan was followed accordingly, and the area was successfully drained without accreted sediment release downstream of the pond sites. Any variations to the drainage plan based on site conditions will be noted and detailed to USACE and NCDWR prior to being implemented. Re-establishment and stabilization of pond-drained portion of Poplin Branch The success of this component will be measured based on whether Poplin Branch re-establishes itself within the drained area to seamlessly connect to both the upstream and downstream reaches surrounding the ponds. Due to the unknown conditions currently within the ponded areas, it is not possible to currently ascertain the condition of the pond beds and the former channel. This complicates preliminarily design and stringent implementation of a natural stream design at this point of the project. Therefore, the project approach is to allow for Poplin Branch begin to establish its natural channel to use as the basis for the Final Stream and Riparian Area Restoration Plan. Channel establishment will be monitored starting with the draining phase of the project and continue throughout the restoration process until the stream channel is deemed stabilized by USACE and NCDWR. Ultimately, success will be based on successful channel stability, survival of live-staked vegetation (if required), and lack of significant bank erosion, channel widening, or down-cutting. Grading of riparian areas exposed by pond drainage The success of this component will be measured based on the continuity of the drained area with the upstream and down- stream riparian areas and floodplains. Grading will aim to grade the drained areas to match the elevation, contours, and slope of the surrounding areas. Another component of the grading plan will be to remove accreted sediment from the drained area to return the area to natural ground; this will occur prior to grading and its removal and proper disposal will be a factor in the success of the restoration effort. Details related to the grading of the drained areas will be developed for the Final Stream and Riparian Area Restoration Plan once site conditions are known. Planting of riparian areas The success of this component will be measured based on success of plantings outlined in the Planting and Monitoring Plans outlined above. A general strategy of how to replant has been developed that includes the initial re-seeding of the riparian area with a native riparian plant seed mix (herbaceous) to provide early stabilization, followed by planting of native riparian woody species (rooted stock; saplings or cuttings) to provide further stability. Monitoring of plantings for up to 5 years and calculating survival based on plants/acre each year will be the primary measure of planting success (which will be approved by USACE and NCDWR). A secondary measure will be the amount of surrounding native species that migrate into the drained area. Establishment of floodplain wetlands Ideally, floodplain wetlands similar to those already present on other portions of Poplin Branch and tributaries to Poplin Branch will establish themselves once the pond have been drained. During annual site monitoring, the site will be assessed for areas that possess characteristics of jurisdictional wetlands such as hydrological, vegetation, and soil indicators. A final delineation will be completed at the end of year 5 monitoring to determine the extent of established wetlands in the area. Success for this component will be the establishment of any wetlands within the de-ponded areas. 8 Establishment of a site protection instrument This request has been provided to the City, which is currently determining the best course of action for this request. A form of site protection instrument, such as a deed restriction or easement, will be pursued to protect the final restored site once it is clear what the likely boundaries of will be in the future. Success will be measured based on the ability to successfully protect the site ad-infinitum. Table 1. Comparison of permanent stream impacts between PCN and revised drawings Site/Sheet No.(PCN Site No.) Original Impact (lin. ft.) Revised Impact (lin. ft.) 7 (S5) 73 83 9 (S8) 71 81 14 (S12) 89 99 Total 233 263 Note 1: It was identified, based on a comment from NCDWR in their September 1, 2020 email, that 10 feet of rip rap in each of the above streams (at the downstream end of each proposed culvert) was not accounted for in the original PCN calculations. This riprap will be countersunk and will not result in a loss of water. These are the only revisions to impacts associated with the project. Note 2: An additional 10 feet of countersunk rip rap will occur at Site 15, on the downstream end of the pipe that separates Ponds PE and PF; a larger temporary rip rap apron will be placed at this location as part of the erosion control plan after the ponds are drained and pared back to the 10-foot pad later in construction. However, this was not calculated as a stream impact, since no stream channel exists at this point in time, and was accounted for in the pond drainage impacts. The final 10-foot pad will not be counted as part of the stream restoration linear footage.
