Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 1.0 PROJECT INTRODUCTION 1.1 PROJECT DESCRIPTION The Beaufort 56 Mitigation Site (“B56 Site” or “Site”) is in Beaufort County, NC and consists of three separate stream systems that include headwater restoration and stream and wetland systems restoration, enhancement and preservation. The on-site headwater systems and stream channels will be restored using a holistic approach that seeks to restore or enhance the valley and riparian wetlands adjacent to the stream channels. This site is proposed to be included in the Middle Neuse Stream and Wetland Umbrella Mitigation Bank (the “Middle Neuse UMBI”). The Site is identified as having potential to help meet the compensatory mitigation requirement for stream and freshwater wetland impacts in Hydrologic Unit Code (HUC) 03020202 of the Neuse River Basin. It was selected based on the site’s ability to provide improvements to aquatic resources within the middle Neuse 8-digit HUC through a combination of restoration, enhancement, and preservation. All mitigation areas within the site will be protected in perpetuity by a conservation easement as described in the Middle Neuse UMBI. The Site is separated into three mitigation areas that include the stream systems, riparian buffer, and riparian wetlands. Most of the on-site streams were historically impacted by extensive ditching and currently have diminished functionality within any or all five of the functional categories identified in the stream functional pyramid (Harman, Starr, Tweedy, Clemmon, Suggs, Miller. 2012). Based on these areas of impacted functionality and potential for functional uplift, this mitigation plan has been produced identifying the proposed mitigation activities and associated credit generation shown in Table 1 and Table 2 (on the following page).

The larger Neuse River Basin has been a focal point for water quality concerns for almost three decades due to sediment disturbances in upstream rural development as well as nutrient loading from upstream agricultural land use. Development within this basin is predicted to increase—especially with the proposed Kinston Bypass 7 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 construction, which will likely increase development around the proposed interchanges. As such, the B56 Site aims to provide protection and the potential for significant water quality and aquatic habitat improvements in this sensitive region through restoring and conserving aquatic resources in the Middle Neuse. The B56 Site was identified as a strong candidate for mitigation based on its potential for uplift as well as the following criteria as originally documented in the prospectus phase: · Access—Potential sites must have permanent, deeded access. · Proximity to Impacts—Potential sites must be within the 8-digit HUC in which impacts are anticipated to occur. · Watershed Impact—Restoring, enhancing, and protecting a potential site must contribute to the overall improvement of the watershed in which it is found. · Restoration Potential—Potential sites must have a combination of wetland and stream restoration, enhancement, and/or preservation. Sites with historical alterations, such as silviculture, will generally be given priority for development. · Habitat Connectivity—Potential sites must contribute to creating larger, contiguous conservation properties to help support habitat diversity, quality, and stability. · Sufficient Water Rights/Resources—Potential sites must have sufficient water rights/resources to sustain restored, enhanced, and/or protected wetlands and streams. · Mineral Rights—The Bank Sponsor must own/control the surface mineral rights, including gravel, sand, salt, and coal. 1.3 MITIGATION SITE LOCATION, SIZE, AND SERVICE ARE A The B56 Site is in southwest Beaufort County, NC, about 23 miles north of New Bern. It can be accessed from Pollard Road off State Road 102, approximately 3 miles east of U.S. Highway 17. The Site is separated into three distinct sections—Beaufort 56A (“56A”), located at 35.4126° North and -77.1526° East; Beaufort 56B (“56B”), at 35.4198° North and -77.1810° East; and Beaufort 56C (“56C”), at 35.4260° North and -77.1615° East (see Figure 1). Overall, the Site includes the restoration, enhancement, and preservation of multiple tributaries and riparian wetlands, some of which currently are within narrow bands of hardwood forest near active timber production. The Site is in the Creeping Swamp sub-basin of the Middle Neuse River Basin (HUC 030202020403) and the Middle Atlantic Coastal Plain Ecoregion. The Site sits in the Department of Water Resources (DWR) Sub-basin 03-04-09. HUC 03020202 is situated downstream of HUC 03020201 (which contains Raleigh and Durham) and HUC 03020203 (which includes Smithfield, Goldsboro, Farmville, and other heavily agricultural areas). The local Creeping Swamp sub-basin is predominantly used for timber production, with some agriculture and very little existing commercial, industrial, or residential development. The B56 Site, as a mitigation site under the framework of the Middle Neuse Umbrella Mitigation Bank (“Bank”), is proposed to produce stream credits that will be used to offset permitted impacts to aquatic resources within the Bank’s service area. The service area associated with the B56 Site is defined as the United States Geological Survey (USGS) 8-digit HUC within which the Site is located - the Middle Neuse 02 HUC (HUC 03020202). 1.4 OWNERSHIP BANK OWNER, SPONSOR, AND LONG-TERM STEWARD Weyerhaeuser NR Company The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 8 Contact: Doug Hughes Address: 406 Cole Road Hattiesburg, MS 39402 Phone: 601 341 6054 Email: doug.hughes@weyerhaeuser.com As the landowner, Weyerhaeuser NR Company will provide access to the property for establishment (including granting the conservation easement), operation, management of the Site, and long-term management of the property within the framework of the Middle Neuse UMBI.

As the Bank Sponsor, Weyerhaeuser NR Company maintains the rights to permit, develop, maintain, and operate the Middle Neuse Bank and its associated sites, including The B56 Site, in accordance with the terms of the Middle Neuse UMBI and the Mitigation Plan and subject to the terms and conditions of the conservation easement that will be established over the property. As the long-term steward, Weyerhaeuser NR Company will be responsible for maintenance of the Site’s aquatic resources as described in the Long-Term Management Plan, in Section 8.7 of this document. Long-term stewardship responsibilities will begin at the end of the bank’s operational phase (after all credits are released and sold) and continue in perpetuity. CONSERVATION EASEMENT HOLDER The conservation easement will be held by Unique Places to Save, a 501 (c)(3) nonprofit conservation organization located in North Carolina. A copy of the conservation easement document is included as Appendix I. 9 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 2.0 WATERSHED APPROACH 2.1 WATERSHED ENVIRONMENTAL CONCERNS AND MITIGATION NEEDS The Middle Neuse River Basin (HUC 03020202) has been significantly impacted by agricultural land uses, extensive ditching, and lack of riparian buffer. Development within this basin is predicted to increase, especially with construction of the Kinston Bypass. This bypass will increase mobility in the area and spur development around proposed interchanges, likely creating additional impacts to the area. The Middle Neuse River Basin (HUC 03020202) consists of 1,008 square miles with more than 340 miles of stream and is primed for significant local growth. Between the five counties that make up the watershed (Beaufort, Craven, Lenoir, Pitt, and Wayne Counties), Pitt County is forecasted to grow by 5.8% by 2020, and Wayne County is expected to grow by 4.1%**. Overall, the Middle Neuse watershed is expected to see 2.4% growth by 2020. The B56 Site represents a valuable opportunity to restore natural streams and headwater systems to offer long-term protection to essential habitat and aquatic resources as growth and development comes to the area. This Site’s goals and objectives described below are consistent in addressing the major stressors identified in the 2010 Neuse River Basin Restoration Priorities (RBRP) document produced by the North Carolina Department of Mitigation Services (NCDMS). **https://files.nc.gov/ncosbm/demog/countygrowth_2020.html 2.2 GOALS AND OBJECTIVES WATERSHED SCALE GOALS The Neuse RBRP 2010 document produced by the NCDMS spells out the Middle Neuse Basin restoration and protection goals. Applicable goals stated are as follows: · Promote nutrient and sediment reduction in agricultural areas by restoring and preserving wetlands, streams, and riparian buffers. · Continue targeted implementation of projects under the Nutrient Offset and Buffer programs, as well as focusing Department of Transportation (DOT)-sponsored restoration in areas where they will provide the ecosystem’s most functional improvement. Mitigation proposed as part of the B56 Site addresses these specific RBRP goals. A significant length of stream mitigation, wetland mitigation, and riparian corridor enhancement and preservation will improve water quality within the Middle Neuse Basin. Additionally, these projects are being implemented now to offset future impacts that could occur as part of the Kinston Bypass construction and future development that may occur because of the roadway improvements. SITE-SPECIFIC OBJECTIVES · Fill ditches that currently are draining headwater valley systems and reestablish the historic headwater valley system to accomplish the following: o Restore hydrology to the headwater valley system to enhance and restore wetland systems within the headwaters o Restore original headwater stream system to provide more frequent flooding of the adjacent headwater wetlands and valley The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 10 o Supplement existing trees and roots in headwater systems with appropriate vegetation to encourage stabilized flow paths through restored headwater systems o Restore native riparian buffers o Restore native wetland vegetation · Restore intermittent and perennial streams with a Priority 1 restoration approach to: o Reestablish the restored channel to the center of its valley and restore appropriate pattern, dimension, and profile. o Because of elevating the stream through a Priority 1 approach, enhance and restore adjacent riparian wetland hydrology. This also will address the cross-sectional dimensions of the channel to return it to a stream hydraulically connected to its floodplain versus its current ditched and disconnected/incised state. o Restore profile and habitat diversity by reestablishing riffle/ripple and pool sequences (i.e., habitat transitions) throughout the restored stream systems to provide depth variability. o Establish a 150-foot-wide vegetated buffer to each site of the Priority 1 restoration and transition reaches. o Establish and/or protect a minimum 50-foot-wide vegetated buffer to each side of the headwater and preservation reaches. o Provide additional buffer, outside the required 50 feet along restored headwater systems, to protect enhanced, restored and preserved wetlands. · Where possible, preserve channel reaches to provide a contiguous riparian corridor throughout the site for each of the three systems. · Reestablish natural overland flow patterns within the adjacent buffers by removing planting rows and disrupting the drainage effect of ditches within the buffer. · Restore natural topography in the floodplains, including minor depression and mounds that promote diversity of hydrologic conditions and habitats. · Restore or enhance site wetland hydrology by promoting storage of surface water, increasing surface ponding and infiltration, decreasing drainage capacity, and imposing a higher water table across the floodplain and wetlands. 2.3 ASSURANCE OF SUFFICIENT WATER RIGHTS, CONTROL OF MINERALS, AND ACCESS Sufficient water rights exist to support the long-term sustainability of the Site. There are no "severed" rights on the property. 2.4 SITE PROTECTION In accordance with Section X (Site Protection) found in the Middle Neuse UMBI, the Bank Sponsor, Weyerhaeuser NR Company, plans to protect the site by applying a conservation easement. A copy of the conservation easement document is included as Appendix I. 11 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 3.0 SITE BASELINE 3.1 EXISTING WATERSHED CONDITIONS There are three separate systems proposed for mitigation as part of the B56 Site (systems A, B, and C). The watersheds for all three systems originate on-site. Silviculture is the primary land use within all three of these headwater systems. In some reaches, a hardwood buffer has been left intact where the adjacent floodplain typically is too inundated for pine harvesting. In these reaches, the center of the valley typically has been ditched, draining the headwater system. Watershed summary information and drainage areas for each separate system are provided in the table below. Table 3 – Watershed Overview Level IV Ecoregion 63e Mid-Atlantic Flatwoods River Basin Neuse USGS 8-digit Hydrologic Unit 03020202 USGS 12-digit Hydrologic Unit 030202020403 DWR Sub-Basin 03-04-09 Project Drainage Area / Percent Impervious Beaufort 56A 807 Ac 0.11% Beaufort 56B 929 Ac 0.32% Beaufort 56C 785 Ac 0.43% These watersheds sit within the Carolina Flatwoods ecoregion (Level IV), which occur in the nearly level coastal plain with frequently high-water tables and large areas of poorly drained soil. While the watershed currently is occupied by significant plantations of loblolly pine forests, the large areas of loamy, organic soils historically were home to significant biological diversity compared to the Mid-Atlantic Flatwood region to the north. Restoring and preserving headwater systems is especially valuable to the health and water quality of the watershed because of its shallow topography. 3.2 EXISTING SITE CONDITIONS SURFACE WATER CLASSIFICATION All reaches identified on-site, including each unnamed tributary and named swamp systems (Pollard Swamp, Creeping Swamp, and Gorham Swamp), are identified as Class C waters with additional designations of nutrient sensitive waters (NSW) and swamp waters (SW). The three systems join in the Clayroot Swamp, which is listed as impaired and drains to an impaired segment of Swift Creek. SITE SOILS The on-site soils are derived from deposits on marine terraces within the coastal plain. These soils were deposited between the Pliocene and Pleistocene epochs, where ocean levels were high enough to form flat terraces across the coast of North America and deposit marine sands, silts, and clays. The on-site soils are described by site section and soil type below. The soils that occur on-site are presented in Figure 4. The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 12 Beaufort 56A Soils Leaf Silt Loam Leaf Silt Loam (La) soils predominantly exist on terraces that form on broad interstream divides and consist of clayey marine deposits. The profile is made up of 0 to 6 inches of silt loam, a depth from 6 to 67 inches of clay, and a final depth from 67 to 80 inches of clay loam (end of profile). This soil type is poorly drained and trends with a 0-2% slope. It has a hydric rating of 90. Leaf soil occurs on-site in the lower portion of the Pollard Swamp reach. Leon Sand Leon Sand (Lo) is a sandy soil that forms on flats in marine terraces created from sandy fluvio-marine deposits during prehistoric periods of high sea levels. The profile consists of medium sand from 0 to 15 inches and fine sand from 15 to at least 80 inches (end of profile).

Beaufort 56B Soils Craven Fine Sandy Loam Craven Fine Sandy Loam (CrB) soils form in ridges on marine terraces. The profile consists of 0 to 9 inches of fine sandy loam, a stretch of clay from 9 to 54 inches, and sandy loam from 54 to 80 inches deep (end of profile). The water table sits consistently between 24 and 36 inches, and the clay layer has a hydraulic conductivity that varies from 0.06 to 0.20 inches per hour. Craven soils are mapped on the southwest edge of the primary stream corridor. Croatan Muck Croatan Muck (Ct) soils form from woody organic material and the water table is frequently at the surface or no more than 6 inches below the surface. The soil profile consists of muck from 0 to 28 inches, mucky sandy loam soils from 28 to 33 inches, sandy clay loam from 33 to 60 inches, and loamy sand from 60 to 80 inches (end of profile). Croatan Muck occurs in the headwater area of the stream system and has a hydric rating of 90. 13 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 Goldsboro Fine Sandy Loam Goldsboro Fine Sandy Loam (GoA) forms on the broad interstream divides on marine terraces and its soil profile has a fine sandy loam layer from 0 to 13 inches and a sandy clay loam layer from 13 to 80 inches (end of profile). The soil profile has a high to moderately-high weighted hydraulic conductivity and the water profile is consistently at a depth between 24 and 36 inches. Goldsboro soils occur adjacent to the stream corridor in relatively small areas along each side. Leaf Silt Loam See description included in the previous Beaufort 56A section. Leaf (La) soils are mapped around the tributary at the western end of the site. Lenoir Loam Lenoir loam (Le) soils are poorly drained and form on marine terraces and in broad interstream divides. The soil has a low hydric rating, with a water table between 1 and 3 feet below the surface and significantly varying hydraulic conductivity. The soil profile consists of a layer down to 8 inches predominantly of loam, followed by a layer down to 63 inches of clay. The final layer is from 63 to 80 inches below the surface consisting of sandy clay. These soils are found on either side of the western tributary outside of the stream valley. Lynchburg Fine Sandy Loam Lynchburg Fine Sandy Loam (Ly) soils form from loamy marine deposits, and have a soil profile made up on fine sandy loam from 0-9 inches, medium sandy loam 9-14 inches, a medium sandy clay loam from 14 to 65 inches, and clay from 65-80 inches (end of profile). The water table fluctuates from 6 to 18 inches below the water surface and has a low hydric rating. A small area of Lynchburg soils occurs midway along the main tributary adjacent to the stream corridor. Rains Fine Sandy Loam Rains Fine Sandy Loam (Ra) soils are highly hydric and are made up of Loamy marine deposits formed on marine terraces along the Coastal Plain.

The soil profile is poorly drained but with high hydraulic conductivity. The water table fluctuates between 0 and 12 inches of the water surface. An area of Rains soil occurs adjacent to the Croatan soils in the site headwaters. Tomotley Fine Sandy Loam See description in Beaufort 56A section above. Tomotley soils occur in the southern portion of the site headwaters. Beaufort 56C Soils Muckalee Loam The Muckalee Loam (Me) is a frequently flooded hydric soil that originates from sandy and loamy alluvium that deposits on broad floodplains. The water table fluctuates at a depth between 0 and 12 inches from The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 14 the surface. The profile consists of 0 to 24 inches of loam and a sandy loam layer from 24 to 80 inches (end of profile). Muckalee soil occurs within the site stream corridor. Rains Fine Sandy Loam See description in Beaufort 56B section above. Rains soils occur within the headwaters of the site streams. BASELINE STREAM CONDITIONS Descriptions of each existing reach condition are outlined below. Figure 6 provides drainage area acreages for each reach and Table 1 provides existing lengths. Additionally, representative photos are included in Appendix B. Beaufort 56A UT1 Reach 1, UT2, and UT3 Historically, reaches UT1, UT2, and UT3 are headwater systems that have been ditched and disconnected from the adjacent floodplain to drain adjacent areas. North Carolina Stream Assessment Method (NC SAM) scores for each reach are low, due to the incised and disconnected nature of the existing conditions, and bank ratios for each reach range from 2.5 to 4.0. NCSAM forms for the stream in Appendix G. UT1 – Reaches 2 and 3 The lower portion of UT1 is an incised channel that has been ditched and currently acts as a roadside ditch. Historically, reaches 2 and 3 were shallow E-type stream channel that formed at the downstream extent of the UT1 headwater system. Currently, due to the incised and ditched nature of the channel, it is disconnected from the floodplain and lacks natural pattern and bedform diversity. The NC SAM rating of the lower reach of UT1 is low, primarily due to its entrenched condition and inability to frequently access its historic floodplain. Beaufort 56B UT1 - Reach 1 UT1 - Reach 1 is a headwater system that has been incised and channelized through a riparian wetland system. The channel historically was ditched coming out of the existing forested wetland system to facilitate increased drainage of the wetland systems. This reach has an NC SAM rating of low due to past manipulation and ditching practices. UT1 - Reach 2 UT1 - Reach 2 is a ditched intermittent stream channel that historically was incised and channelized to drain the adjacent valley for silviculture production. This system lacks any riparian buffer in the upper reach. The entire reach down to the gravel road crossing has been ditched and disconnected from its historic valley/floodplain. This reach has an NC SAM rating of low due to past manipulation and ditching practices. 15 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 UT1 - Reach 3 UT1 - Reach 3 is the reach bounded on the upstream end by the on-site gravel road and on the downstream end by Pollard Road. Historically, this reach has been ditched but is relatively stable. The residence located adjacent to the south side of Reach 2, east of Pollard Road, prevents implementing a Priority 1 stream restoration approach along this reach. A Priority 1 approach could increase base flood elevation (i.e., hydrologic trespass) on the property and structure. The existing channel has a narrow mature mix of pine and hardwood buffer along the channel. The NC SAM rating along this reach is low due to its disconnection from the channel’s historic valley and riparian floodplain. UT1 - Reach 4 UT1 - Reach 4 has an NC SAM rating of medium and has good connectivity with its right floodplain, but is disconnected on the left side by spoil piles on the bank from historic ditching and straightening. UT1 - Reach 5 Baseflow for UT1 - Reach 5 currently is blocked and redirected to the 4- to 10-foot-deep ditch located along the northeast side of the on-site gravel road. The baseflow then follows the ditch northwest along the side of the road until it flows into Creeping Swamp. Due to an existing perched culvert under the gravel road and the road’s low profile, flood flows still run down the historic valley and relic channel of Reach 5 during periods of high flows. The relic stream channel is well-established with existing riparian vegetation and dense root systems in the channel banks to provide immediate stability and habitat when baseflow is returned. Once baseflow is returned to the system, it will have an immediate NC SAM rating of high. UT2 UT2 is a proposed headwater preservation reach with an NC SAM rating of high because of flow within the valley having good connectivity with the floodplain and valley bottom. No distinct channel exists along the upstream/North end of the reach. The contributing drainage area half way down the reach is 80 acres, enough to provide 30 days of continuous flow. Along the Southwest end of the reach flow begins to concentrate enough to form a stable small channel that then ties into the roadside ditch located along the north side of the existing gravel road. This roadside canal then flows northwest along the canal. Beaufort 56C UT1 - Reach 1 UT1 - Reach 1 is a headwater system that historically has been ditched to aid in draining the system and connected ditches within the valley. The reach currently has an NC SAM rating of low due to the system’s ditched and incised nature. UT1 - Reach 2 UT1 - Reach 2 is a preservation reach with a shallow type-E channel that transports flow from the headwater systems of Ut1 - Reach 1 and UT2. The channel has stable geomorphology and habitat and will be preserved within the proposed conservation easement. The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 16 UT2 UT2 is a ditched headwater system that forms below the large upstream headwater wetland system. The system historically was ditched. This ditched system ties into the ditched reach of UT1 - Reach 1. Due to its straightened and incised nature, UT2 has an NC SAM rating of low. BASELINE WETLAND CONDITIONS All areas within the Beaufort 56 site boundaries have been field reviewed and existing wetlands have been delineated. Data forms have been included in Appendix H. While large portions of riparian areas along all three systems (A, B, and C) have hydric soils and, historically, have been headwater and riparian wetlands, many of these areas are non-jurisdictional due to the extensive ditching that exists on- site. The table below provides an overview of wetland resources on the Site. Figure 5 shows existing hydric soils and Figure 7 shows the jurisdictional areas as delineated on all three systems. Only site 56B has extensive wetlands now. The presence of wetlands on each of these systems is dependent on headwater system hydrology and some are more dependent on floodplain connectivity and overland flow for hydrology. Most of these systems have been impacted through ditching the headwater systems as well as ditching and incising the downstream intermittent and perennial stream systems. Depressional hardwood swamp areas along 56A UT1 and 56B UT1-Reaches 3 and 4, are rated excellent in the Natural Heritage Program’s rating system, but site delineations show that much of those systems have altered hydrology and no longer meet wetland criteria.

These parameters, and their associated design considerations, have been developed to fit under the framework of the Harman Stream Functions Pyramid. Maximum practical uplift potential for each functional level, including stream hydrology, hydraulics, geomorphology, physical chemistry, and biology, were scrutinized based on the existing conditions and limitations associated with adjacent land use, watershed condition, and landscape variables. The content of the mitigation plan was guided by these observed functional uplift areas to best serve the project and improve overall site conditions. Table 5 - Stream Mitigation Work Plan Parameter Design Consideration Work Plan (if not functioning or functioning at-risk) Hydrologic Function Surface Flow and Watershed Contribution Overland Flow Restore multi-zone hardwood and vegetative buffer to slow overland flow and reduce sedimentation. Identify areas of concentrated flow such as lateral ditches that enter the proposed conservation easement and fill these ditches and locations of concentrated flow. Also, implement vernal pool or pocket wetlands to dissipate energy and slow water entering the conservation easement. Vegetative Buffer Hydraulic Function Floodplain Connectivity Bank Height Ratios (BHR) Restore natural bankfull dimensions and reestablish hydrologic access to the floodplain by raising existing channel bottoms or designing new channel with appropriate base width and bankfull dimensions based on regional curves and reference reach data. The primary approach throughout all reaches is to reconnect the channel to its historic floodplain by filling in ditches through headwater systems and implementing Priority 1 restoration where feasible. Floodplains and adjacent wetlands will be restored to promote the storage and infiltration of surface water. Entrenchment Ratio (ER) Dimensionless Rating Curve Flow Dynamics Bankfull Velocity Reduce channel erosion and stabilize sediment transport within the channel by selecting bankfull dimensions and channel geomorphology to optimize stream power and velocity, and minimize negative impacts from excess shear stress. Changes to the dimensions of the channels will include construction of a channel with appropriate bank height ratios (1.0) and appropriate bedform diversity to dissipate energy across the floodplain and channel. Bankfull Shear Stress Bankfull Stream Power Groundwater/Surface Water Exchange Meander Width Ratios Reestablish channel pattern and profile, removing existing ditches that drain surrounding groundwater areas. Raised groundwater conditions along the stream banks restores hyporheic zones and allows for groundwater and surface water exchange. Floodplains and adjacent wetlands will be restored to promote the storage and infiltration of surface water. Priority 1 combined with decreasing floodplain drainage capacity will impose a higher water table across the site. Bedform diversity Geomorphic Function Large Woody Debris Large Woody Debris Reestablish hardwood buffer along riparian zone to provide shade, The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 18 Transport and Storage Index (LWDI) compared to reference detritus, and large and small woody debris to supplement habitat provided by in-stream structures in the channel and buffer area. Channel Evolution Rosgen Stream Channel Succession Scenarios (2010) Design new channel with intentional P-P spacing, radius of curvature, riffle slopes, and bankfull dimensions to regulate channel type and development. Simon Channel Evolution Model Stages (1989) Bank Migration/ Lateral Stability Meander Width Ratios Design channels with appropriate width-to-depth ratios and meander widths, as well as radius of curvature, to prevent unnatural bank erosion and excess sedimentation. Plant stabilizing vegetation and live stakes on the banks to reduce bank recession and sedimentation. Bank Erosion Hazard Index (BEHI) Width-to-Depth Ratios Riparian Vegetation Vegetative Buffer Varying widths of vegetative buffers will provide valuable hydrologic and hydraulic benefits to the overbank and transitional areas of the stream reaches and headwater systems, including stabilization, energy dissipation, and natural habitat. Bed-form Diversity Percent Riffle Provide mechanism for channel bedform revitalization through appropriate channel profile and dimensions that will subsequently alter sediment deposition, transport, and channel stability. Introducing proper pool-to-pool spacing and riffle/ripple grades will support deposition of sediment and establishment of stable natural channel bed material. Additionally, wood structures such as log vanes, log cross vanes, brush and roll riffles, and toe wood will be used to provide immediate bedform diversity creating habitat transitions like references Pool-to-Pool Spacing Depth Variability Bed Material Characterization Bed Material Composition Relative to Reference Physicochemical Function Water Quality Vegetative Buffer and Bank Stability Establish vegetative buffer to decrease sediment erosion from overbank areas and from incoming surface flow from outside of the conservation easement. The buffer also will reduce runoff velocities, decreasing potential to erode channel banks. Regrading and planting channel banks (where applicable) will reduce the potential for bank erosion and further reduce sediment loading. Water Temperature Establish Riparian Buffer Establish riparian buffer along headwater systems, as well as ephemeral, intermittent, and perennial streams within the conservation easement. Narrowing low flow when channel is overwide will further reduce temperature. Nutrients In-Stream Riffle Structures Reestablish appropriate channel dimensions and pool-to-pool spacing to restore groundwater to surface water exchange in the channel banks and revitalize hyporheic zones where micro bacteria breakdown and consume complex nutrients from fertilizers, like nitrates into atmospheric Nitrogen. Profile and Bankfull Dimensions Biological Function Aquatic organism communities Aquatic Habitat Revitalize riparian buffer conditions, install instream structures for stability and habitat (brush and roll rifles, brush toe, log vanes, and log cross vanes), and raise channel bed to reconnect flow to the floodplain and enhance hyporheic activity. The installation of riffle structures provides areas for aquatic habitat, as well as areas for turbulence that oxygenates water. Wetland Habitat Groundwater and Surface Water Connectivity 19 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 5.0 MITIGATION PLAN 5.1 REFERENCE SITE AND DESIGN PARAMETERS Design of the proposed restoration and enhancement reaches within the B56 Site were based on multiple considerations and sources of design parameters. The following were used for the stream and wetland design: · Four reference stream sites located within the Carolina Flatwoods level-IV ecoregion · On-site relic channels (56B, UT1-Reach 5) and relic wetland systems · Multiple coastal plain regional curves and accompanying data · Current USACE and NCDMS guidelines/design parameters Searches were conducted upstream/downstream of the Site and into surrounding watersheds to find suitable references that contained similarities to the Site streams including level IV physiographic ecoregion, drainage area, valley slope, and morphology. No reference reaches were identified immediately upstream or downstream of the site or in the surrounding watershed. Four reference reaches from multiple reference databases (NCDOT and Sweet/Geratz) were selected outside of the watershed but within the Carolina Flatwoods level-IV physiographic eco-region. The reference reaches were selected to represent the probable configurations for the proposed streams. The data shown in Table 6 helped to provide a basis for evaluating the project site and determining the stream systems that may have been present historically and/or how they may have been influenced by changes within the watershed. A description of each reference reach is included below. Geomorphic parameters for these reference reaches are summarized in Appendix D. Reference streams provide geomorphic parameters of a stable system, which can be used to inform design of stable channels of similar stream types in similar landscapes and watersheds. While reference reach data can be a useful aid in designing channel dimension, pattern, and profile, there are limitations in smaller stream systems. The flow patterns and channel formation for most reference reach quality streams is often controlled by slope, drainage areas, groundwater inputs and larger trees and/or other deep-rooted vegetation. Some meander geometry parameters, such as radius of curvature, are particularly affected by vegetation control. Pattern ratios observed in reference reaches may not be applicable or are often adjusted in the design criteria to create designs that are less likely to erode after construction, before the permanent vegetation is established. REFERENCE STREAM REACHES Beaverdam Branch The Beaverdam Branch reference reach is located approximately 1,000 ft downstream of SR 1119 outside Trenton, NC in Jones County. Beaverdam Branch is classified as a Rosgen E5 stream type. The stream flows through a wide wooded swamp floodplain with a valley slope of 0.1%-0.4% and sinuosity of 1.9. Most of floodplain would be considered wetland with numerous seeps and side tributaries. The 3.0 square mile watershed is mostly agricultural (70.4% cultivated) with the remainder being bottomland forest/hardwood swamps, shrublands, mixed upland hardwoods, and some single-family residences. The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 20 Black Branch Black Branch is in Craven county just north-west of New Bern off SR 1101, within Croatan National Forest. This site was classified as a blackwater E stream type and has a drainage area of 1.2 square miles. The reach has a valley slope of 0.6% and channel slope of 0.4% giving it a sinuosity of 1.7. The stream maintains an entrenchment ratio of 15-25. The watershed of the reference reach lies almost entirely within the National Forest boundaries made up of predominantly silviculture southern yellow pine with some bottomland forest, mixed upland hardwoods, and mixed shrubland. Tributary to Town Creek The unnamed tributary (UT) to Town Creek is located north of SR 1413 (Town Creek Rd NE) near Belville, NC in Brunswick county. The stream was classified as a blackwater E stream type with a drainage area of 0.6 square miles. This reach flows through a semi mature bottomland forest and has an average valley slope of 0.72% and an average channel slope of 0.35%. The channel has a width-to-depth ratio of 8.9, an entrenchment ratio of over 20, and a sinuosity of 2.0. The watershed for this reference reach is mostly used for cultivated silviculture with some forested land and shrubland. Tributary to Hunters Creek The UT to Hunters Creek is in Jones County, south of Great Lake Road, Croatan National Forest. The drainage area is 0.7 square miles and the land use within the drainage area is comprised of cultivated silviculture, semi mature-mature bottomland forest/hardwood swamps, shrublands, and mixed upland hardwoods. The UT to Hunters Creek reference site was classified as a C6 stream type with a sinuosity of 1.5. The channel has a width to depth ratio of 19 and an entrenchment ratio of 16. The reach has a valley slope of 0.4% while the channel slope is 0.2%. HYBRID ECOREGION-SPECIFIC REGIONAL CURVE The published Rural NC Coastal Plain regional curve (Doll, et al., 2003) along with an additional NC Coastal Plain regional curve (Sweet and Geratz, 2003) was used to check hydraulic geometry based on drainage area using regional relationships. A hybrid level IV ecoregion-specific curve was developed for the Carolina Flatwoods ecoregion using data from the two published regional curves and supplementary data from Kimley-Horn’s internal reference reach database. Analytical review of applicable streams from multiple stream reference databases and developing a hybrid regional curve, provided the most pertinent background information to determine the appropriate design parameters given the existing conditions and overall site functional uplift potential. Additionally, reference parameters from Kimley-Horn’s internal database based on successful past projects were consulted and analyzed. Appendix D illustrates the NC Coastal Plain curves along with other data used for these analyses. HEADWATER REFERENCE In addition to design criteria reference data (mentioned above), design and placement of the headwater restoration reach systems required consideration of the valley slope, contributing drainage area, ground water inputs, curvature, soils, precipitation and Ecoregion. Research provided in “Mapping Headwater Streams: Intermittent and Perennial Headwater Stream Model Development and Spatial Application” by Russell (2008) shows that contributing drainage area is the usually the dominating factor in predicting intermittent and perennial stream points of origin. For the Coastal Plain it was found that the mean 21 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 contributing drainage area at the point of origin of intermittent streams is about 40 acres. For perennial streams that value is about 100 acres.

Relic wetlands within the headwater systems are primarily impacted by extensive ditching through the middle of the valley, which has drained the systems. The relic hydric soils and valley features are already in place. The system uplift will be based on the headwater channel and Priority 1 channel design which will raise the groundwater table. Any wetland enhancement or restoration that results from the stream restoration work will be monitored and tracked. On-site reference wetland systems (preservation area - upper 56B) in similar landscape positions (i.e., headwater or riparian) and mapped soils will provide design and monitoring success criteria for hydrology and vegetative community reference (see Figure 5 for hydric soils and Figure 10 for monitoring locations). DESIGN PARAMETER DEVELOPMENT Design parameters were first based on the existing valley shape and slope, on-site relic stream systems, the reference stream dimensionless parameters, and finally checked and confirmed using multiple regional curves for North Carolina’s Coastal Plain region. Appendix D outlines these developed parameters. The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 22 5.2 MITIGATION WORK PLAN STREAM MITIGATION WORK PLAN The B56 Site is separated into three distinct sections—56A, 56B, and 56C. A summary of the mitigation approach and lengths for each reach is provided in the table below. Table 7 – Stream Mitigation Approach Summary Site Reach Mitigation Approach Existing Length (ft.)

The overall approach to all three systems is to reverse the damage created through ditching. More detailed and reach-specific approaches are outlined below for restoration, enhancement, and preservation reaches, but the overall goal of these approaches is to reconnect the channel flow with its adjacent riparian floodplain and wetlands and restore native vegetation communities to restore lost functions of the system. The design process began with a thorough analysis of existing and historic conditions and functions within the catchment area for each reach and analysis of hydrologic, hydraulic, and geomorphic functional impairments within each reach, wetland, and floodplain. From this data, reference systems (e.g., streams, headwaters, wetlands, and riparian buffers) were selected that represented a stable, healthy system that manages the same or similar baseline conditions. Through a comparison of existing conditions and relic performance, as well as historic conditions, major areas of concern and potential uplift were identified. The concerns include, but are not limited to, bank instability, disconnection from the natural floodplain due to significant ditching, incision, over-widening of existing channels, and wetland and floodplain drainage. Site analysis also identified a significant loss of in-stream and riparian wetland habitat (including sources of shade, woody detritus, and large woody debris for future habitat development). 23 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 These issues will be addressed with a watershed-based approach. Starting at the top of the watershed, we will fill in the ditches within the valley reaches that show potential for headwater system restoration. Downstream of these headwater systems, a Priority 1 approach will be used on systems A and B to continue a reconnection of the stream hydrology to the adjacent floodplain through the valley; thus, raising the water table. This is a valley restoration approach that will benefit adjacent wetland areas and the channel instead of only providing uplift to the channel itself. In addition to raising the invert of the channel back to its historic elevation, the channel will be returned to its original location along the lower portion of its valley and appropriate pattern and bedform diversity (profile) will be restored. Headwater Restoration Approach Description The on-site headwater systems have been ditched to accelerate drainage, damaging the hydrological and ecological functions of these systems. When functioning properly, with gradual progression from linear wetland systems to channelized stream-wetland system, headwaters offer a vital ecological resource and mitigate against nonpoint source pollution from the contributing watershed, as well as critical habitat for aquatic and terrestrial species. Species diversity and frequency benefit from enhanced habitat in the headwater and buffer areas along the entire B56 Site. As such, special focus has been given to addressing major deficiencies in on-site headwater resources and the transitions from upland to headwater and headwater to stream-wetland-floodplain. Reaches UT1 - Headwaters, UT2, and UT3 within the 56A system; reach UT1 - Upper in the 56B system; and reaches UT1 - Reach 1 and UT2 in the 56C system, each represent headwater mitigation and aim to remove ditching and enhance riparian/wetland vegetation for a buffering mechanism. They also aim to provide stabilized flow pathways for overland flow that will reduce sediment contributions from off-site runoff and dissipate energy from potential sources of concentrated flow. Where relevant, new planted vegetation will be selected based on its uplift potential for stability and erosion reduction, as well as its functional value as wetland wildlife habitat. Headwater restoration is proposed to begin on each reach where the cumulative drainage area becomes 40 ac. Research has documented that 40 acres is the average watershed size in the coastal plain region that can support the formation of an intermittent channel. (Russell, 2008) The headwater restoration will continue until the watershed size reaches 100 acres, at which point the work will transition to traditional priority I stream restoration. In general, the headwater restoration approach applied to the reaches listed above will include the following: · Fill the existing ditch (use adjacent spoil piles from original ditching activity). · Fill lateral ditches that tie-in to the existing centerline ditch (using adjacent spoil pile material). · Ensure appropriate organic topsoil exists (site investigations confirmed plenty of organic topsoil material on-site). · Rip and disk the freshly placed soil and areas of construction to ensure soil is not compacted. · Reestablish natural overland flow patterns within the adjacent buffers by removing berms and planted rows and disrupting the drainage effect of ditches within the buffer. · Restore natural topography in the wetland-floodplain, including minor depression and small mounds that promote diversity of hydrologic conditions and habitats. · Restore or enhance site hydrology by promoting surface water storage, increasing surface ponding and infiltration, decreasing drainage capacity, and imposing a higher water table across the valley. · Plant appropriate headwater system woody and herbaceous vegetation. The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 24 · Install woody debris structures to provide immediate stabilization to the freshly filled portions of the ditch footprint (e.g., log sills or brush mattresses). · Install coir fiber matting (as necessary) in some locations where concentrated flow is anticipated. Plant native vegetation within all restored areas as the contractor works their way out of the headwater restoration area and down to the lower stream restoration reaches Stream Restoration Approach Description Priority 1 restoration is proposed for UT1 - Reaches 2 and 3 of system 56A and UT1-Reaches 1 and 5 of system 56B. Restoration activities aim to reconnect flow to the floodplain and provide stable, natural bankfull dimensions, pattern, and profile. These goals are accomplished by filling the existing ditched, incised, and eroding channel and redirecting flow into a newly constructed natural channel that has been sized and aligned based on the following: · Relic stream location · Valley topography/centerline location · Consideration of dimensionless ratios from reference reach conditions · Regional curve data The following specific improvements are incorporated into the restoration reaches on the Site: · Dimension—The channel will be reconnected to its historic valley and floodplain by raising the stream back up from its incised/ditched condition and the channel will have an appropriate bankfull depth. This will restore the groundwater depths in areas directly adjacent to the channel and will allow for more frequent floodplain access for storm flows. · Pattern—The channel will be returned to its historic location within its valley as opposed to its current straight/ditched location. Within the confines and boundary of its historic valley center, the channel’s pattern will be returned based on on-site relic channel patterns, reference reach dimensionless ratios, and regional curve data. · Profile—With a restored dimension and pattern, the profile also will be designed to incorporate bedform diversity with well-defined pools and shallow riffle reaches. In-stream structures will be installed to provide scour for pools and initial grade control until the new riparian vegetation has time to establish the root system necessary to hold the restored system in place. In addition, woody structures—such as the proposed brush and roll riffles and toe-wood—will provide immediate habitat and stabilization for the newly constructed channel. · Riparian Buffer—Beyond restoring the natural channel, the stream restoration approach also reestablishes a native riparian buffer protected with a permanent conservation easement that provides uplift to site hydrology, channel stability, and availability of natural habitat. · Flow Patterns—Within the adjacent buffers, natural overland flow patterns will be reestablished by removing berms, planted rows, etc. and disrupting the drainage effect of ditches within the buffer. · Natural Topography—Natural topography in the floodplains, including minor depression and mounds that promote diversity of hydrologic conditions and habitats, will be restored. · Site Hydrology—Site hydrology will be restored or enhanced by promoting surface water storage, increasing surface ponding and infiltration, decreasing drainage capacity, and imposing a higher water table across the floodplain and wetlands. 25 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 Stream Enhancement Approach Description Reach 4, along the Beaufort 56B section of the site, is the only enhancement reach proposed as part of the Site. The enhancement approach aims to provide uplift to existing conditions by modifying existing banks, buffer conditions, and altering drainage hydrology. Enhancement Level 1 stream system improvements include the following: · Removing berms and spoil piles adjacent to the existing channel to improve overbank flooding frequency. · Stabilizing the outer meander where BEHI or NBS is high or very high by installing log vanes, grading, and installation of coir fiber matting, and bio-engineering (i.e., live stakes and seeding). · Uplift to the profile of the system through the installation of log cross vanes and brush and roll ripples. · Establishing a 150-foot-wide riparian buffer along the left side of the channel and converting existing vegetation from young pine to a hardwood buffer. · Locations of concentrated flow from surrounding land uses will be addressed through the installation of vernal pools or pocket wetlands to slow the water down as it enters the riparian buffer. · Re-establish natural overland flow patterns within the adjacent buffers by removing berms, planted rows, etc. and by disrupting drainage effect of ditches and berms from the buffer Mitigation Approach for Individual Reaches Mitigation approaches for each reach in the B56 Site have been outlined below. Table 7 provides an overview of the suggested mitigation activities that will be employed to achieve the targeted objectives within each reach. Beaufort 56A UT1 – Reach 1 Headwater Restoration – Mitigation activities will aim to restore headwater stream-wetland-floodplain system functionality by filling in the existing ditched channel and restoring appropriate grade, hydrology, and vegetative communities. Existing buffer hardwoods will be preserved and will continue to provide a stabilized flow path for restored stream and riparian wetlands, and a 100 ft buffer will be added to each side of the valley centerline to protect the restored system and regulate incoming surface flow from outside the conservation easement. UT1 - Reach 2 and 3 Priority 1 Restoration – Mitigation activities include raising and re-meandering the channel with appropriate dimensions to reconnect hydrology with the floodplain and restore/enhance riparian wetlands adjacent to the stream. Within the channel, in-stream structures will be installed, including log cross vanes, toe wood, and other woody debris to protect restored banks, maintain channel grade in riffles, and enhance natural habitat within the restored profile. A 150 ft buffer will be added on either side of the stream valley. The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 26 UT2 Headwater Restoration – Mitigation activities will restore headwater stream systems by filling in existing ditched channel and restoring gradual grade and hydrology. Existing trees and roots will be supplemented by tree, shrub, and herbaceous plantings to provide a stabilized flow path for the restored system, and a 100 ft buffer will be planted on either side of the valley. UT3 Headwater Restoration - Mitigation activities will restore headwater stream systems by filling in existing ditched channel and restoring gradual grade and hydrology. Existing trees and roots will be supplemented by tree, shrub, and herbaceous plantings to provide a stabilized flow path for the restored system, and a 100 ft buffer will be planted on either side of the valley. Beaufort 56B UT1 - Reach 1 Headwater Restoration – Mitigation activities will restore headwater stream systems by filling in existing ditched channel and restoring gradual grade and hydrology. Existing trees and roots will be supplemented by tree, shrub, and herbaceous plantings to provide a stabilized flow path for the restored system, and a 100 ft buffer will be planted on either side of the valley. UT1 – Reach 2 Priority 1 Restoration – Mitigation activities include raising and re-meandering the channel with appropriate dimensions to reconnect hydrology with the floodplain and restore/enhance riparian wetlands adjacent to the stream. Within the channel, in-stream structures will be installed, including log vanes, toe wood, and other woody debris to protect restored banks, maintain channel grade in riffles, and enhance natural habitat within the restored profile. A 150 ft buffer will be added on either side of the stream valley. UT1 – Reach 3 Preservation – This reach will be preserved by maintaining a 50 ft buffer on either side of the valley and establishing a permanent conservation easement to protect the natural channel. UT1 – Reach 4 Level 1 Enhancement – Mitigation activities include enhancing the channel by removing spoil piles along the left bank and establishing a buffer (100 ft on the right bank, 50 ft on the left bank) to reduce surface erosion and dissipate overland concentrated flow. Additionally, pocket wetlands will be established along the buffer in areas where concentrated flow from offsite enters the conservation easement. UT1 - Reach 5 Priority 1 Restoration – Mitigation activities include blocking the existing roadside canal that diverts flow, and restoring baseflow and hydrology to the relic channel and valley. A conservation easement will be placed along the existing buffer (150 ft average along both sides of the valley). UT2 27 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 Preservation – This reach will be preserved by maintaining a 100 ft buffer on either side of the valley and establishing a permanent conservation easement to protect the natural channel. Beaufort 56C UT1 - Reach 1 Headwater Restoration – Mitigation activities will restore headwater stream systems by filling in existing ditched channel and restoring gradual grade and hydrology. Existing trees and roots will be supplemented by tree, shrub, and herbaceous plantings to provide a stabilized flow path for the restored system, and a 100 ft buffer will be planted on either side of the valley. UT1 - Reach 2 Preservation - This reach will be preserved by maintaining a 50 ft buffer on either side of the valley and establishing a permanent conservation easement to protect the natural channel. UT2 Headwater Restoration – Mitigation activities will restore headwater stream systems by filling in existing ditched channel and restoring gradual grade and hydrology. Existing trees and roots will be supplemented by tree, shrub, and herbaceous plantings to provide a stabilized flow path for the restored system, and a 100 ft buffer will be planted on either side of the valley. WETLAND MITIGATION WORK PLAN Through restoration of the headwater stream systems and Priority 1 restoration of the downstream systems, riparian and headwater wetlands will be enhanced and restored throughout systems A, B and C. No wetland credits are being proposed for wetland enhancement or restoration along the Priority 1 stream restoration reaches, rather the extra wide buffers (150 feet to each side of channel) will be used for an increase in stream credits where applicable. Based on topography/LIDAR and presence of hydric soils, there are wetlands that are anticipated to be restored through filling of the ditches and restoration of the headwater systems (hydrology and vegetation). These areas will be monitored after restoration to determine the extent of restoration achieved. A summary of the mitigation approach and areas for each system is provided in the table below. Table 8 – Wetland Mitigation Approach Summary System Adjacent to Reach Mitigation Approach Mitigation Area (ac.) 56A UT1 - R1, UT2, and UT3 Restoration 7.57 56B UT1 - R1 Restoration 0.59 56B UT1 - R1 Enhancement 3.90 56B UT1 - R1 Preservation 10.9 56B UT2 Preservation 5.79 56C UT1 – R1 and UT2 Restoration 5.77 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 28 Wetland Restoration Approach Description Wetland restoration and enhancement activities aim to uplift site hydrology, surface and subsurface hydrologic connectivity, vegetation diversity/density/composition/vigor, and to provide improvements that benefit downstream waters. On site wetlands will be restored as part of the headwater stream restoration activities and by converting vegetation from pine plantation to bottomland hardwood forest species. These new plantings will provide flow velocity control, soil stability, habitat, and additional essential ecosystem functions that will provide essential, permanent habitat for local fauna in areas where loblolly pine timbering makes habitat variable and less diverse. Included below is a bulleted list of the proposed activities to be completed to accomplish wetland restoration and wetland enhancement on the site. There are no differences between the restoration and enhancement approaches, both will include improvements in hydrology and vegetation. For tracking potential credits wetland enhancement is designated within areas that have already been delineated as existing jurisdictional wetlands, and wetland restoration is designated within low lying areas adjacent to the stream channel that have hydric soils and appear to be drained relic wetland systems. Activities to restore and enhance these wetland systems include: · Fill existing ditch as part of the headwater stream restoration approach · Fill any lateral ditches that currently drain the wetland restoration areas to the primary ditch · Remove berms and spoil piles that exist along ditches · Remove pine planting rows within the wetland restoration and enhancement areas (as applicable) because they adversely affect drainage · Disk the disturbed areas prior to planting. · Re-establish native wetland vegetation within areas currently in pine production and within disturbed areas · Monitor the restored or enhanced wetland areas for invasive species and treat as necessary to comply with the success criteria outlined in this document VEGETATION AND PLANTING PLAN Planting within the conservation easement has been separated into three zones to reflect differences in purpose and location, as well as differences in vegetation. Zone 1 is located along the stream bank and serves to provide bank stability and in-stream habitat along the channel. Zone 2 makes up the upland riparian buffer of each reach, providing a wide range of benefits including physicochemical and hydrological uplift to the channel as well as overbank habitat and erosion prevention. Zone 3 includes wetland plantings within the riparian buffer. Buffer widths for either side of each reach are provided in Table 9. The plant species proposed for zones 1 and 3 were selected based on reference vegetative conditions and various resources providing guidance on healthy North Carolina Coastal Plain bottomland hardwood communities. Planting ratios were identified based on relevant guidance to restore natural bottomland hardwood conditions that were impacted historically by land use and site manipulations. Tree seedlings will be planted at a density of 500 stems per acre. There is a total of 63 acres to be planted at this Site, which will require 31,500 seedlings. Due to the differences in hydrologic purpose and ecological benefit, different planting profiles are proposed for Headwater and stream mitigation areas. Typical planting sections are provided in the project plan set, Appendix F, sheet 37. 29 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 Table 9 – Proposed Buffer Widths Site Reach Proposed Length Left Buffer width (ft) Right Buffer width (ft) Beaufort 56A UT1 - R1 2,265 100 100 UT1 - R2 3,233 150 150 UT1 - R3 530 150 150 UT2 655 100 100 UT3 897 100 100 Beaufort 56B UT1 - R1 774 150 150 UT1 - R2 2,477 150 150 UT1 - R3 1,297 50 50 UT1 - R4 1,874 50 100 UT1 - R5 1,250 150 150 UT2 1,684 100 100 Beaufort 56C UT1 - R1 1,730 100 100 UT1 - R2 1,000 50 50 UT2 892 100 100 Zone 1 – Stream Bank Channel stability and geomorphology are dependent in large part on the health and strength of stream bank vegetation. As such, live stakes selected for Zone 1 have been identified for their rapid growth rate and high success rates in channel bank conditions. Long term, stream bank vegetative conditions will evolve through natural secondary succession, eventually transitioning to shade tolerant hardwoods like the riparian buffer conditions. The table below provides Zone 1 species for live stake planting within these buffer areas.

Annual monitoring reports will be provided using the IRT monitoring template for the duration of the 7-year monitoring window. The monitoring plan is outlined in Figure 10. 8.1 STREAM MONITORING REQUIREMENTS Vegetative Monitoring Vegetative monitoring will be conducted per the October 24, 2016 “Wilmington District Stream and Wetland Compensatory Mitigation Update” (“NCIRT guidance”) with the exception that the sites are relatively small and the sponsor will increase the percent monitored to obtain an accurate measurement of survival, species variability, and trees per acre. 5% of the total planted portion of the site will be monitored with vegetation plots. The NCIRT guidance states that this area requirement can be adjusted on a case by case basis for these types of sites. A combination of fixed (50%) and random (50%) 0.05 Ac plots will cover 5% of the planted area on site. Planted area acreage was determined based on anticipated supplemental planting to expand existing hardwood areas and replace absent buffers. Tree seedlings will be planted at a density of 500 stems per acre. Planted acreages and monitoring plot counts are provided in the table below. Locations are shown in Figure 10. Table 17 – Vegetative Monitoring Plots Site Planted Area Number of Tree Seedlings to be Planted Vegetative Monitoring Plots Permanent Random Beaufort 56A 23 Ac 11,500 12 11 Beaufort 56B 20 Ac 10,000 10 10 Beaufort 56C 10 Ac 5,000 5 5 Headwater Stream Monitoring Headwater monitoring will be conducted every year for 7 years. Surface flow will be documented using gauges or photo(s) (i.e. time lapse/game cameras) and will be monitored in accordance with the 2016 guidance. Stream Channel Stability and Stream Hydrology Monitoring Channel stability and hydrology monitoring will be conducted, per the 2016 guidance. Due to the narrow width of the channels in the B56 Site, the Bank Sponsor will place two cross sections per 1000 feet of stream. Crest gauges will be installed to monitor channel hydrology and will be capable of monitoring frequency and duration of overbank events. Visual Monitoring Monitoring will be conducted with a walkthrough of the entire project area, looking to identify areas of low stem density, poor plant vigor, prolonged inundation, native and exotic invasive species, beaver activity, herbivory, encroachments, indicators of livestock access, or other areas of concern. Results of both monitoring walkthroughs each year will be reported in the annual monitoring report, where-in recommended courses of action shall be identified where necessary. Any areas of concern will be The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 34 reevaluated on all subsequent visual assessments. Monitoring in preservation areas will be conducted only for ensuring no activities are occurring that are in violation of the restrictions included in the preservation mechanism. 8.2 WETLAND MONITORING REQUIREMENTS MONITORING HYDROLOGY AND REPORTING HYDROLOGIC DATA Monitoring of areas of wetland restoration and enhancement hydrology will be conducted per the 2016 guidance. Installation of groundwater equipment will be in accordance with techniques and standards described in the USACE Technical Standard for Water Table Monitoring of Potential Wetland Sites. Wells will be installed in wetland mitigation areas along Beaufort 56B, and the location of these wells is shown in Figure 10. Hydrologic success of wetlands will be determined based on published guidance (IRT 2016) or through comparison to measured reference condition. 8.3 PERFORMANCE STANDARDS VEGETATION PERFORMANCE STANDARDS Success will be identified based on interim stem density criteria provided in the 2016 NCIRT guidance: · Survival of at least 320 stems per acre at the end of year 3, 260 stems per acre by the end of year 5, and 210 stems per acre at the end of year 7. · Per IRT guidance, coastal plain projects must maintain vegetation that averages 7 feet in height at year 5 and 10 feet in height at year seven. · No one species may comprise more than 50% of the total composition within any plot at year 3, 5, or 7. STREAM CHANNEL STABILITY AND STREAM HYDROLOGY PERFO RMANCE STANDARDS Stream Channel Flow All channels shall receive sufficient flow throughout the monitoring period to maintain an ordinary high- water mark. Continuous surface flow within tributaries must be documented to occur every year for at least 30 consecutive days during the prescribed monitoring period, per the 2016 NCIRT guidance. Channel Stability Bank Height Ratios and Entrenchment Ratios shall meet minimum/maximum requirements as provided in the 2016 NCIRT guidance, and not differ by more than 10% from baseline conditions. Bank Height Ratios shall not exceed 1.2. Entrenchment Ratios shall not be less than 2.2. Bankfull Events The project shall remain stable during 4 separate bankfull events occurring in separate years during monitoring years 1 through 7. 35 The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT │ September 2018 Headwater Stream Flow Performance Standards Success will be based on the standards outlined in the 2016 NCIRT guidance for Headwater Stream Performance Standards with the exception that continuous surface water flow must be documented to occur every year for at least 30 consecutive days for monitoring years 4 through 7. The extensive ditch drainage system that will be filled during restoration activities will require a large amount of material to be moved and placed in the existing ditches. To reduce disturbance within the headwater system existing spoil material from on-site will be used to fill the ditches and some small portions of the ditches will be graded to act as vernal pools. It will take a few seasons for an appropriate number of fines to wash into the system naturally to fill the voids of the newly placed material therefore sealing it up. During years 1 through 3 these fines will work their way into the system and return baseflow to the flow path of the headwater valley system. Visual identification of natural channel formation indicators will be performed in accordance with the schedule provided in the 2016 NCIRT monitoring guidance will. 8.4 EARLY CLOSURE PROVISION If at year 5 the site has demonstrated through monitoring that mitigation activities have been successful without concerns identified, the Sponsor may propose to terminate monitoring of the site and forego monitoring requirements of year 6 and 7. 8.5 ADAPTIVE MANAGEMENT PLAN In the event the mitigation site or a specific component of the mitigation site fails to achieve the necessary performance standards as specified in the mitigation plan, the sponsor shall notify the members of the IRT and work with the IRT to develop contingency plans and remedial actions. 8.6 POST-CONSTRUCTION DOCUMENTATION An as-built survey will be conducted following construction to document channel condition and provide baseline data for comparison to future monitoring reports. Information included in the as-built will be in accordance with USACE guidance and has been identified in the monitoring requirements and performance standards sections. Monitoring reports will be provided to the Wilmington District USACE for review no later than April 1st of the year following the monitoring activity. 8.7 LONG-TERM MANAGEMENT PLAN Land use and property boundaries along with the proposed mitigation plan were designed to minimize long-term management conflicts. As a result, the potential for hydrologic and boundary conflicts have been minimized. The Sponsor has identified Unique Places to Save (a 501 (c)(3) entity) as the grantee of the conservation easement deed. The Bank Sponsor will serve as long-term steward of the site. The recorded conservation easement deed will ensure the protection of the project in perpetuity. The site- protection instrument is provided in Appendix I. 8.8 FINANCIAL ASSURANCES In accordance to Section IX (Financial Assurances) found in the Middle Neuse UMBI, the Bank 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. The Middle Neuse Stream and Wetland Umbrella Mitigation Bank │ Beaufort 56 Site Mitigation Plan – DRAFT September 2018 │ 36 Financial assurances shall be payable at the direction of the USACE to its 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. The amount of the Performance Bond shall be based on costs to implement the Site through monitoring. The Performance Bond shall be in place prior to the first credit release. Since the Bank Sponsor is developing six other mitigation sites simultaneously with this Site, the Bank Sponsor is proposing the use of one Performance Bond to cover all seven mitigation sites. Thus, the costs that are detailed in the table below include the construction and monitoring costs for all seven mitigation sites. Table 18 – Estimated Amount Required for Performance Bond Activity Cost Site Prep Mechanical Rip $5,854.73 Site Prep Disking (to remove any remaining planting beds) $8,131.57 Site Prep Chemical Application (If needed) $5,529.47 Site Prep Prescribed Burn (if needed) $2,276.84 Planting Labor and Seedlings (bottomland hardwood restoration and enhancement areas) $76,255.00 Stream Construction Work (in-stream and riparian buffer work) $2,948,651.06 As-built Report $133,440.00 Annual Monitoring $1,232,323.43 Total Estimated Amount of Performance Bond $4,412,462.10 The USACE will review the as-built and annual monitoring reports to evaluate the success of the ecological restoration. Success will be evaluated based on the Site’s adherence to performance standards specified in Section 8.3. As performance standards are met, the Bank Sponsor will request a reduction in the amount of the performance bond based on the reduction schedule provided in below. The reduction schedule assumes that all seven sites will meet all performance standards on an annual basis. Table 19 – Performance Bond Reduction Schedule.

This number is not used in calculations, but is provided as a reference. Buffer Width Zone (feet from Ordinary High Water Mark) 6Square feet in each buffer zone, as measured by GIS, excluding non-forested areas, all other credit type (e.g., wetland, nutrient offset, buffer), easement exceptions, open water, areas failing to meet the vegetation performance standard, etc. Additional credit is given to 150 feet in buffer width, so areas within the easement that are more than 150 feet from creditable streams should not be included in this measurement. Non-creditable stream reaches within the easement should be removed prior to calculating this area wtih GIS. 5Maximum potential size (in square feet) of each buffer zone measured around all creditable stream reaches, calculated using GIS, including areas outside of the easement. The inner zone (0-15') should be measured from the top of the OHWM or the edge of the average stream width if OHWM is not known. Non-creditable stream reaches within the easement should be removed prior to calculating this area wtih GIS. 2Use the Custom Ratio fields to enter non-standard ratios, which are equal to the number of feet in the feet-to-credit mitigation ratio (e.g., for a perservation ratio of 8 feet to 1 credit, the multiplier would be 8). 1Minimum standard buffer width measured from the top of bank (50 feet in piedmont and coastal plain counties or 30 feet in mountain counties) 3Equal to the number of feet of stream in each Mitigation Type.
