Conceptual Design Plan Appendix — Landowner Authorization Forms Polecat Mitigation Site INSTRUMENT MODIFICATION Neu -Con Umbrella Bank ii May 2016 I INTRODUCTION 1.1 Project Description The Polecat Mitigation Site (the "Site") is located two miles southeast of Smithfield and contains eight parcels totaling 42 -acres in Johnston County, NC. The Site will involve the restoration and enhancement of unnamed tributaries to Polecat Creek and Polecat Creek proper. The Site was identified by EBX-Neuse I, LLC as having potential to help meet the compensatory mitigation requirements for stream impacts in hydrologic unit 03020201 of the Neuse River Basin. The conceptual design presents 12,195 linear feet of stream mitigation generating 9,563 Stream Mitigation Units (SMU). In addition to the stream restoration, the Site is proposing to provide nutrient offset mitigation and riparian buffer mitigation through the NC Division of Water Resources (DWR) Neuse Riparian Buffer Mitigation program. The buffer and nutrient offset mitigation will be developed through a separate banking instrument. 1.2 Project Location The Polecat Site is located in Johnston County approximately two miles southeast of Smithfield, NC (Figure 1). The GPS coordinates of the site are 35.476199°N and -78.312849°W. To access the site from the town of Smithfield, head south on Mallard Road for approximately 1.5 miles. 1.3 Service Area The Site will provide mitigation credits to offset unavoidable impacts to stream and wetland resources within the Upper Neuse subbasin (8 -digit USGS HUC 03020201). The Site is located within the Neuse River Basin (8 -digit USGS HUC 03020201, 14 -digit USGS 03020201140010). This proposed Site will result in significant ecological improvements including water quality improvement, habitat restoration and a decrease in non -point source pollution from stormwater and agricultural practices. The Site is located in the Polecat Creek Watershed, a Targeted Local Watershed (TLW). The Site supports many of the Neuse River Basin Restoration Priorities Plan (RBRP) and Neuse Regional Watershed Plan (RWP) goals. The Site's watershed is primarily rural with Interstate 95 occupying the western portion of the watershed. The project parcels have been in agricultural use for several decades (Figure 3). Water quality stressors currently affecting the Site include livestock access, row crop production, and impervious surface. There are no current conservation easements or options that conflict with the proposed mitigation bank. All waters in the Neuse River basin are Impaired on an evaluated basis in the Fish Consumption category for mercury contamination. This is based on fish consumption advice from the NC Department of Health and Human Services (NC DHHS). Downstream in the Neuse River, low dissolved oxygen levels are present. 1.4 Identified Watershed Needs The North Carolina Division of Mitigation Services (DMS) develops River Basin Restoration Priorities (RBRP) to guide its restoration activities within each of the state's 54 cataloging units. The 2010 Neuse River Basin RBRP identified several restoration needs for the entire Neuse River Basin, as well as for Polecat Mitigation Site INSTRUMENT MODIFICATION Neu -Con Umbrella Bank 1 May 2016 HUC 03020201, specifically. Goals include promoting nutrient and sediment reduction in agricultural areas by restoring and preserving streams, wetlands, and riparian buffers. The proposed Site is designed to help meet these goals. The project will address stressors identified in the watershed through nutrient removal, sediment removal, runoff filtration, and improved aquatic and terrestrial habitat. These project goals will be achieved through stream enhancement and restoration. 1.5 Purpose and Objectives The purpose of the proposed Site is to generate compensatory mitigation credits for inclusion in the Neu - Con Umbrella Mitigation Bank in hydrologic unit 03020201 of the Neuse River Basin. The project goals address stressors identified in the watershed, and include the following: • Nutrient removal, • Sediment removal, • Invasive species removal, • Filtration of runoff, • Wildlife corridor enhancement and preservation, and • Improved aquatic and terrestrial habitat. The project goals will be addressed through the following project objectives: • Elimination and control of exotic invasive species, • Restoration of riparian forested stream buffers • Stabilization of eroding stream banks due to lack of vegetation and livestock hoof shear, • Addition of large woody debris such as log vanes, log weirs, and root wads, and • Restoration of appropriate pattern, dimension, and profile in stream channels. The proposed Site will provide numerous ecological and water quality benefits within the Neuse River Basin. These benefits are not limited to the project area, but have more far-reaching effects throughout the Neuse River. The Site will provide improvements to water quality, hydrologic function, and habitat. 1.6 Technical Feasibility The technical feasibility of the bank is assured due to EBX-Neuse I, LLC's extensive experience with stream and wetland restoration and enhancement in North Carolina and throughout the Southeast. Examples of EBX-Neuse I, LLC's success with stream restoration and enhancement include Neu -Con Umbrella Mitigation Bank sites: the Gregory, Nahunta, and Cox II Sites. The absence of fatal flaws such as hydrologic trespass, and the absence of threatened and endangered species and their habitats mean the project is unlikely to be impeded by resource issues, or by objections from landowners. 1.7 Site Ownership The land required for the construction, management, and stewardship of this mitigation project includes portions of the parcels listed in Table 1.

The Site will be delineated and approved by the USACE during the decision phase of the project. Carolina Division of Water Quality methodology, 3.2 Soil Survey 3.2.1 General Soil Characteristics The stream channels were classified using North The Site is located in the Rolling Coastal Plains Physiographic Province. Existing soil information from the Natural Resource Conservation Service (MRCS) shows the property is located within the Rains - Goldsboro -Lynchburg soil association. This association is found on nearly level and gently sloping well drained to poorly drained soils on uplands of the coastal plain region. This soil association is located on broad level interstream areas that are relatively undissected by streams (Figure 4). 3.2.2 Site Mapped Soil Series Site soils are mapped by the NRCS as Bibb, Cowarts, Goldsboro, Lynchburg, Toisnot, and Norfolk on the low lying depressions and floodplains at the proposed project. Bibb, Goldsboro, Lynchburg, and Toisnot soils are generally poorly drained sandy loam to loamy soils and range from 0 to 2 percent slopes. Cowarts and Norfolk soils are typically loamy sands and are well -drained located on 0 to 6 percent slopes. Bibb, Goldsboro, Lynchburg, and Toisnot soils are listed on the NRCS hydric soil list as hydric or having hydric inclusions. The surrounding upland soils are mapped as Cowarts, Gilead, and Norfolk. These soil types are typically moderately well to well drained soils. Both Cowarts and Norfolk soils are loamy sands and are found on slopes ranging from 2 to 6 percent. Gilead is a sandy loam soil and is generally mapped in locations ranging from 2 to 8 percent slopes. 3.3 Endangered/Threatened Species Plants and animals with a federal classification of endangered or threatened are protected under provisions of Sections 7 and 9 of the Endangered Species Act of 1973, as amended. The US Fish and Wildlife Service (USFWS) database (accessed 11 May 2016) lists four endangered species for Johnston County, North Carolina: Red -cockaded woodpecker (Picoides borealis), Tar River spinymussel (Elliptio steinstansana), Dwarf wedgemussel (Alasmidonta heterodon) and Michaux's sumac (Rhus michauxii). No protected species or potential habitat for protected species was observed during preliminary site evaluations (Table 2). The Bald eagle (Haliaeetus leucocephalus) is protected under the Bald and Golden Eagle Protection Act (BGPA) and prohibits take of bald and golden eagles. No protected species or potential habitat for protected species was observed during preliminary site evaluations. Polecat Mitigation Site INSTRUMENT MODIFICATION Neu -Con Umbrella Bank 5 May 2016 In addition to the USFWS database, the NC Natural Heritage Program (NHP) GIS database was consulted to determine whether previously cataloged occurrences of protected species are mapped within one mile of the project Site. Results from NHP indicated that there is one known occurrence west of the Site within a one -mile radius of the project area. The NHP database documented a terrestrial habitat of Red -cockaded woodpecker historically mapped in 1999. Based on initial site investigations, no impacts to federally protected species are anticipated as a result of the proposed project. The environmental screening phase of the project will include USFWS coordination to confirm these findings. Table 2.

There are low-density residential lots, maintained vegetation, and two-lane roads also present in the immediate project vicinity. Forested riparian areas have been intermittently cattle -grazed and lack a well-developed understory and shrub strata. These areas most closely resemble a disturbed Coastal Plain small stream swamp and are dominated by hardwoods and loblolly pine (Pinus taeda). Canopy species include loblolly pine, blackgum (Nyssa sylvatica), red maple (Acer rubrum), sweetgum (Liquidambar styraciflua), and willow oak (Quercus phellos). Sub -canopy species include red cedar (Juniperus virginaiana) and American holly (Ilex opaca). Some exotics were noted, including Chinese privet (Ligustrum sinense), Nepalese browntop (Microstegium vimineum), and Japanese honeysuckle (Lonicera japonica). Chinese privet and Nepalese browntop are widespread and locally dense. National Wetland Inventory (NWI) mapping depicts wetlands in the project area (Figure 5). During the initial evaluation, riparian wetlands were identified but are not prevalent. All potential wetland areas in the project corridor will be delineated during the mitigation plan phase of the project. 3.5 Cultural Resources A review of North Carolina State Historic Preservation Office (SHPO) GIS Web Service (accessed 11 May 2016) database did not reveal any listed or potentially eligible historic or archeological resources in the proposed project area. The environmental screening phase of the project will include SHPO coordination to confirm these findings. Polecat Mitigation Site INSTRUMENT MODIFICATION Neu -Con Umbrella Bank 6 May 2016 3.6 Constraints Several potential constraints are present or proposed on the Site. Up to four proposed crossings will be constructed for landowner access in easement breaks. The crossings will utilize appropriate sized culverts and floodplain culverts (if needed) and be fenced and gated to prevent livestock access to stream channels in pasture areas. The Site is not located within five miles of an air transport facility (airport). The project crosses Yelverton Grove Road (NCDOT) and EBX-Neuse I, LLC is proposing to utilize the existing culvert and elevation. A 30 -foot powerline easement is located across the channel parallel to Yelverton Grove Road. The proposed Atlantic Coast Pipeline (ACP) is currently shown crossing the upstream -most project reach at an oblique angle. The pipeline route is still in preliminary planning and no easements or landowner negotiations have occurred. RES will coordinate with ACP staff to ensure the Final Mitigation Plan and construction plans adequately address the proposed pipeline. The ultimate site design will minimize ACP impacts and protect the functional uplift of the mitigation project. Polecat Creek within the project area is mapped as a FEMA 100 -year floodplain (Figure 6). RES and WK Dickson Project Engineer will conduct a FEMA flood study to either obtain a No -Rise Certification or CLOMR/LOMR from the Johnston County floodplain administrator. Construction access is slightly constrained in some areas by existing mature hardwood vegetation. A tree survey will be conducted to design the mitigation measures and access to minimize impacts to specimen trees. 4 PROPOSED BANK CONDITIONS 4.1 Conceptual Mitigation Plan The Polecat Site presents the opportunity to provide up to 9,563 stream mitigation units. These will be derived from Restoration, Enhancement Level I, Enhancement Level II, and Buffer Enhancement/Stream Preservation. Table 3 details the mitigation types and SMUs generated. The proposed conceptual design plan is shown in Figure 7. This Site proposes to utilize the non-standard buffer width credit adjustment guidance for Piedmont and Coastal Plain streams. This guidance allows for stream credit yields to be adjusted +7 percent for buffers 75 to 100 feet wide to +20 percent for buffers over 150 feet wide. The buffer adjustment for each bank is averaged and to determine the final adjustment for that reach. The increased stream credit yield precludes the use of the additional buffer area for riparian buffer mitigation.

The stream system is situated on an unnamed tributary to Polecat Creek. Current stream conditions along the proposed restoration reaches demonstrate significant habitat degradation as a result of impacts from livestock, row crop production, and historic land uses. Polecat Mitigation Site INSTRUMENT MODIFICATION Neu -Con Umbrella Bank 8 May 2016 The proposed mitigation approach is based on preliminary data collected, functional considerations, and generally accepted practices in North Carolina. Over 20 cross sections were measured across the Site to assess the stability of the stream bed and banks. Photographs were taken at all cross sections and at selected locations throughout the Site to record general site conditions, including vegetation, stability, and water quality issues. Restoration reaches will typically include a meandering single -thread stream pattern constructed to mimic the natural planform of a low -gradient, sand/gravel bed channel. Proposed sinuosity will depend on local reference reach conditions and hydrologic and hydraulic modeling. As a result of the restoration of planform and dimension, periodic flooding and restored riparian buffer will provide the appropriate hydrology and sediment transport throughout this watershed (mitigation ratio l:1). Enhancement Level I will include adjustments to the cross-sectional area of the existing channel and floodplain; as well as installation of wood and rock structures to adjust and enhance bedform (mitigation ratio 1.5:1). Enhancement Level Il treatments include livestock exclusion and bank stabilization (mitigation ratio 2.5:1). Buffer Enhancement/Stream Preservation allows high quality aquatic habitat to be protected and enhanced through invasive species treatments and supplemental plantings in the riparian buffer (mitigation ratio 5:1). Invasive species treatment will occur throughout the easement area as needed. 4.1.2 Stream Restoration and Enhancement Stream restoration efforts will be accomplished through analyses of geomorphic conditions and watershed characteristics. The design approach will apply a combination of analytical and reference reach based design methods that meet objectives commensurate with both ecological and geomorphic improvements. Proposed treatment activities may range from minor bank grading and planting to re-establishing stable planform and hydraulic geometry. For reaches requiring full restoration or extensive enhancement, natural design concepts will be applied and verified through rigorous engineering analyses and modeling. The objective of this approach is to design a geomorphically stable channel that provides habitat improvements and ties into the existing landscape. The Site design approach will begin with a thorough study of existing conditions, including the on-site streams and ditches, valleys, and watershed. Design parameters, including active channel, habitat and floodplain features will be developed from analysis of suitable reference streams. Analytical design techniques will be an important element of the project, and will be used to determine the design discharge and to verify the design as a whole. Engineering analysis will be performed using various hydrologic and hydraulic models to verify the reference reach -based design. A combination of methods, including HEC -HMS, Hydraflow Hydrographs, and flood frequency analysis, will be used to calculate flows received by the channel for bankfull and other significant storm events. A HEC -RAS model will then be used to simulate water surface elevations of flows generated by the hydrologic analysis. The development of the HEC models is an important component to the design; therefore, model input parameters are field verified when possible. Through this hydrologic analysis, the design discharge (typically referenced as bankfull or dominant discharge) will be determined. The subsequent design will be based on this calculated discharge. Design parameters developed through the analyses of reference reach data and hydrologic and hydraulic modeling will be Polecat Mitigation Site INSTRUMENT MODIFICATION Neu -Con Umbrella Bank 9 May 2016 confirmed using the Stable Channel Design function and/or the Sediment Transport Analysis components within HEC -RAS. Engineering analyses are performed concurrently with geomorphic and habitat studies. While stream design will be verified by simulations of hydrology and fluvial processes, analogs of desirable habitat features will be derived from reference sites and integrated into the project design. Both in -stream and riparian habitat features will be designed. In -stream structures such as root wads, rock vanes, and cross weirs will be used throughout the project to act as grade control and for bank stabilization by dissipating and redirecting the stream's energy. Bank stability may be further enhanced through the installation of brush mattresses and cuttings bundles consisting of species such as black willow (Salix nigra) and silky dogwood (Cornus amomum). In -stream habitat is highly dependent on available cover and organic material. A quantitative habitat assessment method will be used to measure type, location, and quantity of habitat in the reference streams. During design, the habitat assessment results will be scaled appropriately to the design parameters such that the quantity and placement of the habitat features along the restored channel will mimic reference conditions. This process provides a natural channel design that addresses aquatic function improvements in addition to stability. Stream banks will be stabilized using a combination of grading, erosion control matting, plantings, native material revetment techniques (i.e., bioengineering), and structure placement. The stream and adjacent riparian areas will be protected by a minimum 50 -foot permanent conservation easement which will be fenced to exclude livestock as needed. In most areas the riparian buffer width will exceed 100 feet on each bank. The individual Reach Worksheets provide detailed information for each reach and the rationale for proposed interventions.

If changes do take place, they should be evaluated to determine if they represent movement toward a less stable condition (for example down -cutting or erosion), or are minor changes that represent an increase in stability (for example settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less than 2.2 within restored reaches. Channel stability should be demonstrated through a minimum of two bankfull events documented in the seven-year monitoring period. 4.1.3.4 Vegetative Success Criteria Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover approximately two percent of the planted area. The following data will be recorded for all trees in the plots: species, height, planting date (or volunteer), and grid location. Monitoring will occur each year during the monitoring period. The interim measures of vegetative success for the site will be the survival of at least 320 planted three-year old trees per acre at the end of Year 3 and 260 five-year old trees per acre at the end of Year 5. The final vegetative success criteria will be the survival of 210 trees per acre with an average height of 10 feet at the end of Year 7 of the monitoring period. Invasive and noxious species will be monitored and controlled so that none become dominant or alter the desired community structure of the site. If necessary, EBX-Neuse I will develop a species-specific control plan. Polecat Mitigation Site Neu -Con Umbrella Bank INSTRUMENT MODIFICATION 26 May 2016 4.1.3.5 Adaptive Management The Mitigation Plan will include a detailed adaptive management plan that will address how potential problems are resolved. In the event that the site, or a specific component of the site, fails to achieve the defined success criteria, EBX-Neuse I will develop necessary adaptive management plans and/or implement appropriate remedial actions for the site in coordination with the IRT. Remedial actions will be designed to achieve the success criteria specified previously, and will include identification of the causes of failure, remedial design approach, work schedule, and monitoring criteria that will take into account physical and climatic conditions. If tree mortality affects 40 percent or greater of the canopy in a stream or wetland restoration area, then a remedial/supplemental planting plan will be developed and implemented for the affected area(s). 5 BANK ESTABLISHMENT AND OPERATION 5.1 Establishment and Operation of the Bank This Bank Parcel shall be established under the terms and conditions of the Neu -Con Umbrella Mitigation Bank made and entered into by and among EBX-Neuse I, LLC, and the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency, the U.S. Fish and Wildlife Service, the National Marine Fisheries Services, the North Carolina Department of the Environment and Natural Resources, the North Carolina Division of Water Resources, and the North Carolina Wildlife Resources Commission, collectively, the Mitigation Banking Review Team. 5.2 Proposed Credit Release Schedule All credit releases will be based on the total credit generated as reported by the as -built survey of the Mitigation Site. The pre -construction credit release (15 percent) will be based on the credit total in the Final Mitigation Plan. The second credit release will be based on the As -Built survey, and will adjust the total released credits based on the actual constructed channel lengths. Under no circumstances shall any mitigation project be debited until the necessary DA authorization has been received for its construction or the District Engineer (DE) has otherwise provided written approval for the project in the case where no DA authorization is required for construction of the mitigation project. The DE, in consultation with the Interagency Review Team (IRT), will determine if performance standards have been satisfied sufficiently to meet the requirements of the release schedule below. In cases where some performance standards have not been met, credits may still be released depending on the specifics of the case. At the direction of the DE, in consultation with the IRT, monitoring may be required to be extended, depending on the extent to which the site fails to meet the specified performance standard. The release of project credits will be subject to the criteria described in Table 4. Polecat Mitigation Site INSTRUMENT MODIFICATION Neu -Con Umbrella Bank 27 May 2016 Table 4.

(100%**) * * 10% reserve of credits to be held back until the bankfull event performance standard has been met. 5.2.1 Initial Allocation of Released Credits The initial allocation of released credits, as specified in the mitigation plan can be released by the IRT with written approval of the DE upon satisfactory completion of the following activities: 1. Approval of instrument modification by the DE, in consultation with the IRT; 2. Approval of a final Mitigation Plan; 3. Confirmation that the Bank site has been secured; 4. Delivery of executed financial assurances as specified in the Mitigation Plan; 5. Delivery of a copy of the recorded long-term protection mechanism as described in the Mitigation Plan, as well as a title opinion covering the property acceptable to the DE; and 6. Issuance of any DA permits necessary for construction of the Bank site (if necessary). Polecat Mitigation Site INSTRUMENT MODIFICATION Neu -Con Umbrella Bank 28 May 2016 5.2.2 Subsequent Credit Releases The second credit release will occur after the completion of implementation of the Mitigation Plan and submittal of the Baseline Monitoring Report and As -built Survey. All subsequent credit releases must be approved by the DE, in consultation with the IRT, based on a determination that required performance standards have been achieved. As projects approach milestones associated with credit release, the Sponsor will submit a request for credit release to the DE along with documentation substantiating achievement of criteria required for release to occur. This documentation will be included with the annual monitoring report. 5.3 Financial Assurances The Sponsor shall provide financial assurances in the form of a Performance Bond to the IRT sufficient to assure completion of all mitigation work, required reporting and monitoring, and any remedial work required. Financial assurances shall be payable at the direction of the USACE to his designee or to a standby trust. Financial assurances structured to provide funds to the USACE in the event of default by the Bank Sponsor are not acceptable. A financial assurance must be in the form that ensures that the USACE receives notification at least 120 days in advance of any termination or revocation. 5.4 Proposed Ownership and Long -Term Management EBX-Neuse I, LLC, acting as the Bank Sponsor, will establish a Conservation Easement, and will monitor the Site for a minimum of seven years. The Mitigation Plan will provide detailed information regarding bank operation, including long term management and annual monitoring activities, for review and approval by the Interagency Review Team (IRT). Upon approval of the Sites by the IRT, the site will be transferred to a long-term land steward (to be determined in the Mitigation Plan). The long-term steward shall be responsible for periodic inspection of the site to ensure that restrictions required in the Conservation Easement or the deed restriction document(s) are upheld. Endowment funds required to uphold easement and deed restrictions shall be negotiated prior to site transfer to the responsible party. The Bank Sponsor will ensure that the Conservation Easement will allow for the implementation of an initial monitoring phase, which will be developed during the design phase and conducted by the Bank Sponsor. The Conservation Easement will allow for yearly monitoring and, if necessary, maintenance of the Site during the initial monitoring phase. These activities will be conducted in accordance with the terms and conditions of the Neu -Con Wetland and Stream Umbrella Mitigation Bank made and entered into by EBX-Neuse I, LLC, USACE, and NCDWQ. 5.5 Assurance of Water Rights Sufficient water rights exist to support the long-term sustainability of the site, as there are no "severed" rights on the property.
