The Project area exhibits reduced hydrology and habitat value as a result of past and on -going agricultural activities. The Project involves the restoration, enhancement, and preservation of streams and wetlands in the Cape Fear River Basin. The Project has been designed in concurrence with the Cloud and Banner Riparian Buffer Mitigation Bank. RES previously requested and received Nationwide 27 authorization in May 2019 for this mitigation project. After the permit was received, we identified that we omitted a culvert from the design that would be needed to fully access the site. RES has previously corresponded with you regarding this omission. This request is being submitted for a modification of the permit to allow for installation of this culvert. The original proposed total wetland impacts resulting from the proposed project are 0.389 acres. Total stream impacts resulting from the project were proposed at 1,423 linear feet. The total buffer impacts resulting from the project were proposed at 33,809 square feet. These values have been updated. The proposed total wetland impacts remain the same at 0.389 acres. The new total proposed stream impacts are 1,468 linear feet and the new total proposed buffer impacts are 35,797 square feet. For this submittal, we are including the revised PCN submittal form and supporting figures. Thank you for your prompt attention to this important project.

Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:* The Cloud and Banner Mitigation Site (the Project) is a stream, wetland, and buffer project located within a watershed dominated by agricultural, forested and low intensity residential land use in eastern Alamance County, North Carolina, approximately three miles North of Mebane. The Project is within the Haw River Basin and Jordan Lake Watershed, in the Cataloging Unit USGS HUC 03030002, 12-digit USGS Hydrologic Code 030300020405. The Project area is contained within three parcels. where the conservation easement covers a total of 59.76 acres. Back Creek is the main hydrologic feature in the Project. There are also four unnamed tributaries and seven wetland areas included in the Project. Land use at the Project is characterized by regularly harvested hayfields, abandoned pasture, and disturbed bottomland forest. The total drainage area at the downstream limits of the Project is 9,292 acres (14.52 m12). The land use in the project watershed is approximately, 50 percent forested, 45 percent agricultural, four percent residential, and one percent open water. Due to its location and proposed improvements, the Project will provide numerous ecological and water quality benefits within the Cape Fear River Basin. There is currently a total of 8,043 (7,529 of that linear feet are being used to generate credit) existing linear feet of stream on -site, made up of Back Creek and four unnamed tributaries (UT2, UT4, UTS, and UT6) that drain to Back Creek. There are 11.16 acres of existing wetlands within the Project (WA, WB, WC, WD, WE, WF). Furthermore, the United States Fish and Wildlife Service (USFWS) National Wetland Inventory Map depicts six areas of wetlands within the project limits. In the northeast corner there is a small area of PEM1A (Palustrine, Emergent, Persistent, Temporarily Flooded) to the east of Back Creek. Near the southern boundary there are two areas of PEMtAd (Palustrine. Emergent, Persistent, Temporarily Flooded, Partially Drained/Ditched) to the wrest of UT4 and a portion of a PFO1A (Palustrine, Forested, Broad -Leaved Deciduous, Temporarily Flooded) near the confluence of UT6 and Back Creek. In general, all or portions of Back Creek, UT2, 1174, UTS, and UT6 do not function to their full potential. Current conditions demonstrate significant habitat degradation as a result of impacts from historic land uses, and water diversion. Having been channelized in the past, some of the streams do not access their floodplains as frequently as they naturally would have prior to alteration. In most cases, the riparian buffer is in poor condition, where much of the riparian buffer is devoid of trees or shrubs. Habitat along the majority of the restoration reaches is poor with little woody debris or overhanging vegetation for fish cover or protection for other aquatic species. 4b.

Explain the purpose of the proposed project: * The objective for this stream, wetland, and buffer mitigation project is to restore and enhance design natural waterways with the appropriate cross -sectional dimension and slope that will provide function and meet the appropriate success criteria for the existing streams and wetland complexes. Accomplishing this objective entails the restoration of natural stream characteristics, such as stable cross sections, planform, and in -stream habitat. The floodplain areas will be hydrologically reconnected to the channel to provide natural exchange and storage during flooding events. Furthermore, wetland re-establishment and enhancement activities will include: reconnecting low-lying areas of hydric soil with the floodplain along restoration reaches, creating a rough soil surface to aid infiltration, and planting native tree species. The design will be based on reference conditions, USACE guidance, and criteria that are developed during this project to achieve success. Additional project objectives include restoring the riparian buffer with native vegetation, ensuring hydraulic stability, and treating invasive species. 41. Describe the overall project in detail, Including Indirect Impacts and the type of equipment to be used:' The Project will include the following treatments for project streams: Priority I and II Restoration, Enhancement Level 11, Enhancement Level III, and Preservation. Additionally, the project will include the following wetland treatments: re-establishment, enhancement, and preservation. Priority I Restoration reaches will incorporate the design of a single -thread meandering channel with parameters based on data taken from the reference site described above, published empirical relationships, NC Regional Curves, and hydrologic and hydraulic analyses. As a result of the restoration of planform and dimension, frequent overbank flows and a restored riparian buffer will provide the appropriate hydrology and sediment transport throughout this watershed. Engineering analyses were performed using various hydrologic and hydraulic models to verify the reference reach -based design. A combination of methods (including Hydraflow Hydrographs, regional curves and flood frequency analysis) were used to calculate flows received by the channel for bankfull and other significant storm events. Through this hydrologic analysis, the design discharge (typically referenced as bankfull or dormant discharge) was determined, and the subsequent design was based on this calculated discharge. Design parameters developed through the analyses of reference reach data and hydrologic and hydraulic modeling were confirmed using the Stable Channel Design function components within HEC-RAS and through spreadsheet tools. Engineering analyses were performed concurrently to geomorphic and habitat studies. While the stream design was verified by simulations of hydrology and fluvial processes, analogs of desirable habitat features were derived from reference sites and integrated into the project design. Both riparian habitat features and in -stream structures such as log grade controls, brush toes, log vanes, log toes, log drops were used throughout the project to act as grade control and for bank stabilization by dissipating and redirecting the stream's energy. Bank stability may further be enhanced through the installation of brush mattresses, live stakes and cuttings bundles. Sections of abandoned stream channel will be backfilled with material excavated from onsite to the elevation of the floodplain in areas adjacent to the new channel, installing channel plugs where necessary. The floodplain will be planted with native species creating a vegetated buffer, which will provide numerous meter quality and ecological benefits. Stream banks will be stabilized using a combination of grading, erosion control matting, bare -root plantings, native material revetment techniques (i.e., bioengineering), structure placement, and sod transplants where possible. The Project has been broken into the following design reaches: Bade Creek Enhancement Level II is proposed along Back Creek to address existing impairments, particularly, floodplain dislocation, bank erosion, and buffer degradation. The watershed that drains through the project is approximately 14.3 square miles, and land use is primarily forested and agricultural. The project will address limited instream habitat and bank erosion by grading existing banks to reestablish bankfull depth and installing bank protection and habitat measures in select areas. The riparian buffer will also be revegetated along the entire reach, on both banks, to a minimum width of 75 feet, and up to and exceeding 150 feet in some sections. A 63-linear foot reach break is proposed downstream of the existing UT2 alignment to allow for an existing ford crossing to be retained and rehabilitated. Near the confluence of UT2, Back Creek partially flows outside of the easement boundary for 399 feet before it re-enters the boundaries. This section of Back Creek will not generate credit but will receive Enhancement Level II treatment. Preservation is proposed for the last 621 linear feet, before Back Creek ultimately leaves the conservation easement. Reach UT2 A combination of Preservation, Priority I Restoration, and Priority II Restoration is proposed for Reach UT2 to address existing impairments, particularly aggradation, degradation, bank erosion and floodplain dislocation. The UT2 watershed is approximately 51 acres, and land use is an even mix of forest and rural residential. Priority I Restoration is proposed for the upstream portion of UT2 (designated as UT2-A). The restoration approach will involve meandering the proposed channel within the natural valley, installing grade control/ habitat structures, backfilling the existing stream and excavating a new channel. A minimum buffer width of 50 feet will be provided for all portions of the reach. An existing culvert on UT2-A will be removed and relocated upstream, outside of the easement, installed as a permanent culvert. This will be used for future site acees by the landowner. Preservation is proposed for the portion of UT2 (designated UT2-B) located within the existing wetland (Wetland D). Priority II Restoration is proposed for UT2 just downstream of the existing wetland. This reach (designated as UT2-C) will have a 79-foot crossing that will not be used to generate credit but will receive Restoration treatment. The restoration approach will involve meandering the proposed channel within the natural valley, installing grade control/ habitat structures, backfilling the existing stream and excavating a new channel. A minimum buffer width of 50 feet will be provided for all portions of the reach. Downstream of Wetland F, 115 linear feet of UT2-C flows outside of the easement boundary where Enhancement Level I treatment will be conducted but not be used to generate credits. Reach UT4 A combination of Priority I Restoration and Priority II Restoration is proposed for Reach UT4 to address existing impairments, particularly degradation, bank erosion and floodplain dislocation. The UT4 watershed is approximately 73 acres, and the land use is heavily forested. Priority I Restoration is proposed for UT4, however the restoration approach will transition from Priority I to Priority II as the stream profile lowers to tie to Back Creek. Both restoration approaches will involve meandering the proposed channel within the natural valley, installing grade control/ habitat structures, and backfilling the existing stream. The Priority I portion of stream will be reconnected to its natural floodplain, and a new floodplain will be excavated for the Priority II section of stream. A minimum buffer width of 50 feet will be provided for all portions of the reach. A 24-linear foot easement break is proposed in the middle of the reach to accommodate a proposed ford crossing. Reach UT5 Enhancement Level III is proposed for Reach UT5 to address existing impairments, particularly buffer degradation. The UT5 watershed is approximately 155 acres, and the land use is heavily forested. A minimum buffer width of 50 feet will be provided for all portions of the reach. Treatment along UT5 will mostly consist of riparian buffer planting along the right bank, and invasive species treatment. Reach UT6 A combination of Restoration and Preservation is proposed for Reach UT6 to address existing impairments, particularly degradation, bank erosion. and floodplain dislocation. The UT6 watershed is approximately 32 acres, and land use is an even mix of forest and rural residential. Restoration is proposed for the upstream portion of UT6 (designated as UT6-A). This will include the installation of grade control structures to step down to the floodplain/wetland area, where the stream dissipates into Wetland E, as well as floodplain grading/reconnection along the right bank. Preservation is proposed for UT6 (designated as UT6-B beginning at its intersection with the existing wetland and extending to the confluence with Back Creek. Furthermore, there is a portion of UT6 between the restoration and preservation treatments that hits the floodplain and dissipates into the wetland; this area was determined to be non -jurisdictional during the IRT site visit and no credits will be sought for this portion of the reach. Wetland treatments are as follows: Wetland A - Wetland A is proposed as preservation and will benefit from the channel filling of the old UT4 alignment during Restoration and allowing reconnection of the hydrologic system to the wetland restoration component of Wetland B. Welland B - Portions of Wetland B are proposed for re-establishment, while some are proposed for enhancement. Those areas being re-established will benefit from the Priority I stream restoration treatment along UT4. Activities will include meandering the proposed channel within the natural valley, installing grade control/ habitat structures, backfilling the existing stream, and creating shallow depressions within the old channel. Additionally, this area will be planted with native tree and shrub species commonly found in Bottomland Hardwood Forests. The areas being enhanced in WB will benefit from the adjacent wetland preservation and by providing connectivity to the restoration component of Wetland B. Wetland C - Portions of Wetland C are proposed for re-establishment, while some are proposed for enhancement. Those areas being restored will benefit from the plugging of several ditches in the wetland, and the planting of native tree and shrub species commonly found in Bottomland Hardwood Forests. The area being enhanced will also be planted and benefit from the plugging of adjacent ditches. Wetland D - Portions of Welland D are proposed for re-establishment, while some portions are proposed for preservation. Welland D will benefit from the restoration that is proposed for the upstream portion of UT2. This will include removal of an undersized 15-inch CMP and corresponding crossing that have caused significant sediment deposition upstream. The existing spoil pile located along the right bank from the crossing downstream to the intersection of UT2 will also be removed. Moreover, portions of wetland D that are not forested will be planted with native tree and shrub species commonly found in headwater forests. Wetland E and F - Wetlands E and F are proposed for preservation only, these areas will remain intact. 4j. Please upload project drawings for the proposed project.

Comments: Wetland impacts associated with restoration efforts occurring adjacent to the existing wetlands will be minimized by the restoration plan. Creating a new stream channel and enhancing existing channels will only impact wetlands slightly and will provide an overall increase in wetland function with the addition of native trees and shrubs along the stream banks. Construction in these areas will remove the invasive species. There will be a total of 0.389 acre of wetland impacts, of which 0.071-acre will be permanent impacts, and the remaining 0.318-acre is made up of temporary impacts. Although there are wetland impacts associated with the Project. the Project proposes the wetland re-establishment of 6.88 acres, and wetland enhancement of 1.21 acres; therefore, no mitigation is proposed. 3.

Comments: Impacts due to the relocaton of the stream to its natural valley will provide a net gain in ecological function to the stream and wetland system. Restoration is proposed to address channel degradation and bank erosion along these reaches: Stream Impact 1, where the existing length is 320 linear feet (LF), and the new length will be 329 LF; Stream Impact 2, where the existing stream length is 206 LF and the new length will be 516 LF; and Stream Impact 3, where the existing stream length is 852 LF and the new length will be 1,083 LF. Due to the removal of existing culverted crossings (S4 and S5), temporary impacts will occur to a minimum of a 15-linear foot area on either side of both existing culverts, totaling 30-linear feet of temporary impacts at each site. The impacts are needed to support removal of the culverts. After the removal of the culvert, ford crossings will be Installed at the locations and surface stream flow will be restored across these areas. Due to the removal and relocation of the culvert on UT2-A, Stream Impact 6 will include 25 LF of permanent impact and Stream Impact 7 will include 20 LF of temporary impact. 6.

Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:' Due to the nature of this project, complete avoidance is not possible. Both stream and wetland impacts were considered when designing the Cloud and Banner Mitigation project. This project should uplift the ecological quality of streams and wetlands on site. The emsting channel length is 8,043 LF (7,529 of which is considered inside the project area). The proposed project will result in 8,593 LF of stream (8,079 LF will be used to generate mitigation credit). The ersting wetland area within the easement is 11.27, and the proposed wetland area is 18.04. See tables in attachments to this submittal 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:* Impacts are minimized using a staged construction approach. Where possible the channel will be constructed prior to redirecting stream Flow into a segment. This approach allows minimization of the impact of each stage during the project construction. Additionally, all work in wetlands and streams will be conducted during dry conditions and/or with mats to protect soil structure. Efforts will be made to preserve individual high value trees located within the stream restoration area. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State? r- Yes 6 No 2b. If this project DOES NOT require Compensatory Mitigation, explain why: This is a mitigation project which will generate net uplift and compensate for impacts on -site.

All buffer impacts and high ground impacts require diffuse flow or other form of stormwater treatment. If the project is subject to a state implemented riparian buffer protection program, include a plan that fully documents how diffuse flow will be maintained. All Stormwater Control Measures (SCM)s must be designed in accordance with the NC Stormwater Design Manual. Associated supplement forms and other documentation shall be provided. What type of SCM are you providing? r Level Spreader r Vegetated Conveyance (lower SHNT) r Wetland Swale (higher SFNVf) f Other SCM that removes minimum 30 % nitrogen W Proposed project will not create concentrated stormwater flowthrough the buffer (check al tad apply) For a list of options to meet the diffuse flow requirements, click here.

Is this a NCDOT project subject to compliance with NCDOTs Individual NPDES permit NCS000250?'` r'Yes 6No 2b. Does this project meet the requirements for low density projects as defined in 15A NCAC 02H .1003(2)?* F Yes r' No To lookup low density requirement click here 15A NCAC 02H .1003(2). Comments: This is a mitigation project which will not result in net changes to impervious area. Additionally, the project will experience a net uplift due to the nature of the work, including reconnecting stream channels to their floodplains and planting forested buffer along the streams on -site. G. Supplementary Information 1. Environmental Documentation 1a. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? r Yes (.- No 2. Violations (DWR Requirement) 2a. Is the site in violation of DWR Water Quality Certification Rules (15A NCAC 2H .0500), Isolated Wetland Rules (15A NCAC 2H .1300), or DWR Surface Water or Wetland Standards or Riparian Buffer Rules (15ANCAC 2B.0200)?' r' Yes (-- No 3. Cumulative Impacts (DWR Requirement) 3a. Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? r' Yes (-. No 3b. If you answered "no," provide a short narrative description. This project will not result in any additional development that would impact water quality downstream. Utimately, there will be an increase in water quality within the project, due to the restoration and enhancement of project streams, planting of the riparian buffer, and the establishment of a conservation easement to be protected in perpetuity. 4. Sewage Disposal (DWR Requirement) 4a. Is sewage disposal required by DWR for this project? k r Yes r' No r WA 5. Endangered Species and Designated Critical Habitat (Corps Requirement) Sa.

If yes, explain how project meets FEMA requirements: Inspection of the FEMA Flood Insurance Rate Map indicates that a majority of Back Creek and associated floodplains are located within a Zone AE flood area, with significant portions of the project located within the FEMA floodmay. Back Creek is named East Back Creek in the FEMA Flood Insurance Study. it is a FEMA Limited Detailed Studied Stream and is subject to all applicable floodplain development permitting requirements. A hydrologic analysis will be completed on the ebsting and proposed conditions of this reach. it is not anticipated that a No -Rise or a Conditional Letter of Map Revision (CLOMR) will need to be prepared for the Project.
