Introduction Hopkins Farm Mitigation, LLC (Hopkins Farm) is pleased to submit this prospectus for the proposed Hopkins Farm Mitigation Bank (Bank) located in the Cape Fear River Basin, Hydrologic Unit Code (HUC) 03030002. This prospectus was prepared in accordance with C.F.R. §332.1-8 (2008), Compensatory Mitigation for Losses of Aquatic Resources, and was based on current District Guidance, which is subject to the approval of the United States Army Corps of Engineers in consultation with the NC Inter -Agency Review Team (NCIRT). The purpose of the Bank is to provide stream and wetland mitigation credits to compensate for unavoidable impacts to Waters of the U.S. authorized under section 401 and 404 of the Clean Water Act, Section 10 of the Rivers and Harbors Act, and all applicable state statutes. 1.1 Project Location The proposed Bank is located in Caswell County, North Carolina in the Cape Fear River Basin, HUC 03030002. The Bank centroid is located at 36°17'03.9"N 79°24'23.1"W (Figure 1), approximately 2.5 miles north of its boundary with Alamance County and approximately 1.5 miles southwest of Jericho (Figure 2). The proposed Bank will protect approximately 43 acres in a permanent conservation easement. The easement is located on two parcels, which are used for residential and agricultural purposes. 1.2 Service Area The Bank will provide compensatory mitigation credits to offset unavoidable impacts to stream resources within the Cape Fear River Basin (8-digit HUC 03030002). The bank site is further characterized by the 12- digit HUC 030300020401 which is located within a NC Targeted Local Watershed. 1.3 Purpose and Objectives The overall goal of the proposed Bank is to provide complete functional uplift and ecosystem restoration to the headwaters of an impaired stream and its adjacent floodplain. The bank is proposed to generate compensatory mitigation credits in the Cape Fear River Basin. The goal will be achieved through the following objectives: - Nutrient and sediment removal through the filtration of runoff - Elimination and control of exotic invasive species - Improve aquatic and terrestrial habitat by restoring the riparian forested stream buffers - Restore and enhance stream channels using natural steam design techniques and - Restoring and enhancing hydrology of wetlands and bottomland hardwood habitats 1.4General Need and Technical Feasibility The Project will provide numerous water quality and ecological benefits within the Benton Branch, Toms Creek, and Cape Fear River watersheds. The main water quality stressors in the Cape Fear River basin, as outlined in its Basin wide Plan (2005), are habitat degradation, fecal coliform bacteria, and low dissolved oxygen. In HUC 03030002, the Cape Fear River Basin Restoration Priorities (RBRP; NCEEP, 2009) states that the primary goal within this HUC is to reduce nutrient inputs into B. Everett Jordan Lake, a drinking water Hopkins Farm Mitigation Bank SAW-2023-01803 Page 4 of 75 supply that is listed as Nutrient Sensitive Water. This watershed includes the Haw River and all tributaries that have their terminus at Jordan Lake. The Bank's streams drain to Benton Branch which drains to Stony Creek. That part of Stony Creek to which the Bank's streams drain is impounded to form Lake Cammack, one of the primary water reservoirs for the City of Burlington. Downstream of Lake Cammack, Stony Creek flows less than 1 mile and is then impounded as Stony Creek Reservoir, which discharges directly to the Haw River approximately 3 miles further downstream. Therefore, the proposed Bank presents an opportunity to implement a restoration project that will contribute to improve water quality in multiple drinking water reservoirs and throughout the Haw River watershed through exclusion of livestock and restoration of woody riparian buffers along the Bank's streams. In addition, the Bank will also restore aquatic habitats that are currently degraded by livestock access and stream bank erosion; re-establish riparian wetlands by reconnecting streams to their historic floodplains; and restore appropriate hydrophytic vegetation. As part of the proposed Project, there is the opportunity to improve more than 8,400 feet of stream and the improvement of over 12 acres of wetland. This proposed work would restore riparian buffers at least 75 feet in width along all stream reaches, and much wider in many locations, and provide significant overall reductions in nutrients, sediment, and fecal coliform supplied to the Haw River watershed (Table 1.1).

Existing Conditions 3.1 Existing Channel Geomorphic Characterization EPR staff conducted field investigations to evaluate and document the existing conditions of the Bank. These studies, conducted in August and September 2020, included cross-section surveys, photographic documentation, bank erosion and channel incision documentation, and documentation of other observed site conditions and stressors. The proposed Bank was submitted as a NC Division of Mitigation Services (DMS) Full Delivery project in 2020 and passed the technical evaluation required for consideration by the DMS. Site conditions were confirmed in April and June of 2023. A summary of the significant geomorphic parameters is provided in Table 3.1 and collected field data are provided in Appendix B. Locations of the features evaluated during the field investigations are shown in Figure 15. Areas of documented erosion are provided in Figure 10, areas of channel incision are provided in Figure 9, and watershed stressors are illustrated in Figure 4. The Bank's stream systems are predominantly gravel bed transport channels with clear indications of past vertical instability, which is beginning to translate into lateral migration. Many of the Project reaches have been channelized and straightened for agricultural activities or timber harvesting (See Figures 5A through 5C) and range from slightly incised to fully incised and entrenched. The overall reach stressors are agricultural impacts, mainly direct cattle access, anthropogenic channel modification, specifically channelization and straightening, in -stream constructed impoundments, and partial to complete removal of the riparian buffer vegetation. These historic practices have resulted in channel incision, entrenchment, mass wasting of banks due to channel evolutionary processes, localized channel scour, degradation of adjacent riparian wetlands, and poor riparian habitat throughout the stream network. UT4, UTS, and UT8 appear as dashed blue lines on the USGS Topographic Quadrangle Map (Figure 6). The presence of historic valleys for all the project stream systems can be seen from the USGS Topographic Quadrangle Map and on LIDAR imagery for the Site (Figure 7). Given the number of reaches across the project, reaches have been grouped together where possible when discussing the specific stressors and conditions in detail in the following paragraphs. Table 3.1 Summary of Existing Condition Stream Data PROJECT WATERSHED ENT. WIDTH/DEPTH TYPICAL BANK ROSGEN REACH DRAINAGE RATIO RATIO HEIGHT RATIO CLASSIFICATION AREA (AC.)

The alterations include: 1) relocation of the channel in various places along each reach; 2) installation of farm crossings and creation of artificial incision points, the effects of which often migrate; 3) reduction in quality, diversity, and density of the riparian buffer through timber harvesting; and 4) manipulation of the floodplain to decrease riparian wetland function. In addition to these alterations, cattle have had direct access to these streams for many years. The consequences of these influences are vertical and lateral instability from widespread incision and entrenchment, which manifest through steep vertical banks, mass wasting of banks, toe erosion, cross channel bar development, and poor bedform diversity. These reaches classified as either Rosgen F or B channels, depending on whether they exhibited low or moderate entrenchment ratios, respectively. However, each of these reaches exhibited high bank height ratios and localized to systemic instability. Hopkins Farm Mitigation Bank SAW-2023-01803 Page 9 of 75 3.1.2 Reach UT8 UT8 is a small to mid -size stream with an inline pond used for cattle watering. The installation of the pond is the most notable alteration to the system, converting habitat type in the immediate vicinity of the pond and promoting incision and entrenchment along downstream reaches. Cattle have direct access to these entire systems and can often be seen wading in the pond or using the buffer for shade. The constant pressure has compacted the floodplain, decimating the natural understory and significantly decreasing any wetland functions within the riparian corridor. UT8 has incised deeper and is classified as a Rosgen G channel in most sections. 3.1.3 Reaches UT4A — UT4E All the smaller streams on -site, UT4A - UT4E, have been disturbed by past timbering practices. The surrounding buffer is immature and there are signs of logging access and ditching in some of the floodplains and terraces. Non-native species have moved into these buffers causing reduced wetland function and buffer health. A subset of these streams, UT4C and UT41D are displaying various signs of instability. UT41D has experienced headcuts in their downstream extents, both of which have migrated through each system. Often the headcut is still visible at the top of the reach draining the upper headwater wetland. UT41D is classified as a Rosgen G with toe erosion and bank failures indicating a transition towards a Rosgen F channel. UT4C is classified as a Rosgen E channel and is low to moderately incised with increased signs of lateral migration. The channels have undercut banks along outer bends, active bank failures, and minimal vegetative cover for protection. 3.2 Existing Conditions of Wetlands Riparian wetlands are present across the Bank but appear to cover much less extent than they would have historically. Channel alterations, incision, and ditching, as described above, have altered the hydrology of many of the existing wetlands, and drained a number of acres that likely supported wetland communities Hopkins Farm Mitigation Bank SAW-2023-01803 Page 10 of 75 and functions prior to land use changes and alterations. Livestock access has also altered vegetation communities and soil conditions. 3.3 Soils & Geology The Bank is located in the Piedmont physiographic province, which is characterized by gently rolling, well- rounded hills and long low ridges with a few hundred feet of elevation difference between the hills and valleys. The Bank is located in the Carolina terrane, which consists of heated and deformed volcanic and sedimentary rocks. The terrane contains rocks associated with a series of oceanic volcanic islands about 540 to 630 million years ago. The Bank is specifically located in the Carolina Slate Belt, which was formed in the Late Proterozoic -Cambrian period and consists of Metamorphosed gabbro and diorite, foliated to massive. As shown in Figure 8, mapped soils in the project area are Enon, Frogsboro, and Chewacla, Loams. The Enon series generally consists of very deep, well drained, slowly permeable soils on ridgetops and side slopes in the Piedmont. Enon soils are mapped along all of the stream valleys within the Site. Frogsboro soils are considered very deep, somewhat poorly drained soils that are commonly mapped on interfluves. Frogsboro soils are mapped along the upper terraces and side slopes of the Site, and in some cases the stream heads of some of the Project stream reaches. Chewacla soils are very deep, somewhat poorly drained soils that are commonly found along Piedmont River valleys. Chewacla soils are only mapped along the upper reach of Benton Branch within the Project. To further investigate soil conditions on the Bank, Ground Truth Soil Consulting, PLLC (Ground Truth) was contracted to conduct on -site hydric soil investigations to determine the presence or absence of hydric and poorly drained soils within the proposed project area. On -site investigations, consisting of hand - turned auger borings, were conducted in September 2020 by Ground Truth , a licensed soil scientist, as required for this RFP. Seventy-five (75) soil borings were advanced throughout the study area and placed into one of the two categories below: • Hydric soils — soils that met specific hydric indicators (often indicator F3 — Depleted Matrix). Most hydric soils showed signs of manipulation from past agricultural and timber practices. • Somewhat poorly drained soils — soils showing characteristics indicated of somewhat poorly drained soils were mapped in the upper reaches of headwater streams and along incised stream systems. These areas likely represent locations of historically wetter moisture regimes where seasonal wetlands would typically be located. Ground Truth concluded that the Site exhibited evidence of alteration through past and present cattle production and lowering of the groundwater via stream incision and loss of hydrology. Identified hydric soil units are prime candidates for wetland re-establishment and enhancement, while areas of somewhat poorly drained soils will benefit from restored hydrology and could likely be reclassified as hydric. See Appendix E for the hydric soil and site investigation report, including soil boring information and soils mapping. 3.4 Potential Bank Constraints Hopkins Farm Mitigation Bank SAW-2023-01803 Page 11 of 75 3.4.1 Existing Easements on the Bank There are no identified existing easements or constraints that will affect the implementation of the proposed Project. 3.4.2 Mineral or Water Rights Issues There are no mineral or water rights issues within or adjacent to the Bank. 3.4.3 Hydrologic Trespass Upon review of the Federal Emergency Management Agency's (FEMA) National Flood Insurance Program's Digital Flood Insurance Rate Mapping (DFIRM), the Bank is located within a FEMA Area of Minimal Flood Hazard (Zone X), as mapped on Flood Map 3710898200J, effective date 9/28/2007 (Figure 12). No coordination with FEMA or the local floodplain administrator will be required. 3.4.4 Cultural Resources This project is not anticipated to have any adverse impacts on cultural or historical resources. On -site investigations and landowner knowledge have not revealed any potential resources of this type on the property. The NC State Historic Preservation Office (SHPO) will be contacted to ensure no cultural or historical resources will be impacted. 3.4.5 Threatened and Endangered Species Table 3.2 lists the species found in Caswell County that are protected under the Federal Endangered Species Act. Potential habitat is very limited within the project boundaries for the listed species. US Fish and Wildlife Service (USFWS) and the NC Natural Heritage Program (NCNHP) will be consulted with to ensure that there will be no impacts to protected species.

Hopkins Farm Mitigation Bank SAW-2023-01803 Page 12 of 75 3.4.6 Conditions Affecting Hydrology Beavers have historically been active within the Project area but there do not appear to be any active dams or lodges currently. If beaver dams do develop during the development of the Bank, the dams and beavers will be removed in their entirety during construction and monitoring periods. The removal of beavers is not expected to adversely affect the hydrology of the site. Hopkins Farm, or through contracted third parties, will extensively manage beaver on the Bank site during the monitoring period. There is a culverted farm road crossing near the location where UT8 enters UT4. This culvert will remain in place. Therefore, design elevations will tie into this reference point. There are several ditches throughout the Project. These ditches were historically used to drain wetlands and create arable land for farming. These ditches will be plugged during restoration activities to prevent them from negatively affecting hydrology on the completed project. 3.4.7 Adjacent Land Use The Bank's adjacent land use is primarily agriculture and forestry activity. None of these land uses will have negative impacts on the operation of the Bank. Hopkins Farm Mitigation Bank SAW-2023-01803 Page 13 of 75 4. Proposed Conditions 4.1Conceptual Mitigation Plan The plan for the Hopkins Farm Stream and Wetland Mitigation Project involves the potential restoration and enhancement of more than 8,400 feet of stream and the improvement of over 12 acres of riparian wetlands (Figures 14A and 14B). The proposed Project will reestablish, rehabilitate, and enhance the functions of riparian wetland systems and restore a stable headwater stream -wetland complex. Aquatic resources on the Bank have been impacted by past channelization, ditching, direct cattle access, loss of riparian buffers, in -stream impoundments, and past land use. 4.1.1 Stream Restoration Approaches The stream restoration approaches for the Project are divided into two categories: restoration, and enhancement level 2.5. These approaches were chosen based on the existing stream condition, channel evolutionary stage, adjacent wetland function, and riparian buffer health. The categories, associated practices, and applicable streams are discussed further in the following paragraphs. Streams UT4, UT4C, UT41D, UTS, and UT8 (either portions or the entire reach) will require a full-scale restoration approach. These are highly degraded and moderately to highly incised due to past anthropogenic alterations and/or natural stream incision in response to land use changes. As a result, riparian wetlands along these reaches have been significantly impacted and lost. One of the primary goals of the proposed stream restoration efforts is to rehydrate adjacent wetland areas to promote increased riparian wetland acreage and function. The design approaches for the reaches will involve reconnecting the streams to active floodplains and restoring natural channel form (Priority Level I and II Restoration Approaches). By restoring proper stream form, historically removed through channelization and incision, and reconnecting the streams to a functional floodplain, the following functional improvements will be achieved: • Reestablishment, Rehabilitation, and Enhancement of Adjacent Riparian Wetlands — Based on observed soil profiles and existing wetland areas, it is apparent that wetlands were once prevalent along much of the floodplain areas of the streams. A considerable amount of existing wetlands are already present along these floodplains but are functioning at a reduced level. Raising of the stream beds and reconnection to an active floodplain, along with restoration of natural stream forms, will promote higher water table conditions in the streamside area, more overbank flooding, and expanded wetland acreage and function. • Filtration of Flood Flows —Currently, discharges significantly higher than the bankfull discharge are carried within the incised stream channels. Reconnection to an active wetland floodplain will provide filtration of flood flows through native vegetation, effectively reducing storm flow energies and velocities. • Improved Buffer Function — Higher water table conditions associated with reconnecting the floodplain will promote better denitrification of groundwater flowing to the stream channels. Reestablished, rehabilitated, and enhanced wetland areas adjacent to the stream will promote increased plant uptake and retention of surface runoff before reaching the stream channels, minimizing overland flow velocities while also encouraging nutrient removal processes. Hopkins Farm Mitigation Bank SAW-2023-01803 Page 14 of 75 • Reduced Water Quality Impacts — By simply excluding livestock from the project area, significant reductions in direct input of nutrients and fecal coliform will be achieved. Excavated floodplain reaches (Priority Level 2 design approach) will likely be required in several locations to tie to existing stream grades near the Project boundary. Design approaches will ensure that all excavated floodplain areas allow for the design meander belt width. This width is considered practical and achievable based on available floodplain widths measured in the field. In some locations, natural pinches in the valley topography may necessitate tighter floodplain widths. For excavated floodplain areas, depths will be undercut so that excavated topsoil can be replaced to approximately 8 to 10 inches in depth to achieve final design floodplain grades. Good quality topsoil will be stockpiled separately during construction activities to be used in the replacement of topsoil in excavated areas. The slopes between the outer edge of the floodplain grading and the terrace will be a minimum of 5:1 unless natural hill slope topography dictates the need for steeper slopes. Reach UT8 has an in -stream impoundment that will be removed to restore the stream and riparian wetland systems. The earthen dam will be breached, and the dam will be partially to entirely removed such that proper floodplain function can be restored through the restored valley and connect with the floodplain downstream. Restoration of these reaches will focus on not only restoring stable stream conditions but also maximizing riparian wetland extent and function. The remaining small channels, UT4A, UT413, UT4E, and a portion of UT8, are in more stable conditions overall and will receive the less intensive enhancement approaches. These reaches are small enough or have transitioned into a stream/wetland complex to have minimal in -channel stress. Areas that need stabilization will be achieved through vegetation practices such as live staking or sod matting, with structure placement needed to address vertical and lateral stability. The focus in these areas will be improved buffer function through vegetation management practices, enhanced channel stability and habitat, native plantings, and cattle exclusion. For all approaches, in -stream structures will be constructed from materials naturally found at the Bank such as hardwood logs and brush, with the use of quarried rock and stone only as required. There is considerable amount of natural rock piled around the farm that will be used when practical for rock structures. EPR will use methods of structure design and construction that have proven successful on numerous past projects, and practices that have been well received by regulatory agencies. Finally, the proposed buffer widths to be protected by the conservation easement have been maximized to the fullest extent practical. The minimum buffer width for all streams within the Project is 75 feet with many extending out over 100 feet. Wetland Reestablishment, Rehabilitation, and Enhancement The re-establishment, rehabilitation, and enhancement of riparian wetland areas along the floodplains of the Project streams will be critical components of the ecosystem restoration design for the Bank. Existing wetlands on the Bank are degraded due to drainage, primarily through stream channelization, cattle access, loss of vegetation, and mass wasting and erosion of adjacent streams. Re-establishment practices will consist of restoring wetland hydrology and vegetation to areas of hydric and poorly drained soils that do not currently support wetland function. Wetland hydrology will be reestablished by raising the restored stream beds, removing drainage features, and restoring natural Hopkins Farm Mitigation Bank SAW-2023-01803 Page 15 of 75 wetland microtopography. Rehabilitation practices include improvements to hydrology through increased over -bank flooding and reduced drainage, and improvements to vegetation through restoration of a wooded canopy with appropriate native species. Enhancement practices are proposed at two different credit ratios: 2:1 and 5:1. Enhancement 2:1 will be used in locations where either wetland hydrology or wetland vegetation will be improved. Enhancement 5:1 will be used in locations where the practices proposed include cattle exclusion, invasive species treatment, and some supplemental plantings. Species selection for re -vegetation will generally follow those suggested by Schafale (2012) for similar communities and tolerances cited in WRP Technical Note VN-RS-4.1 (1997). Tree species planted across the floodplain areas will likely include a mixture of the following species which have been observed on the site or are endemic to this area: river birch (eetula nigra), various oaks (Quercus spp.), tulip poplar (Liriodendron tulipifera), American elm (Ulmus americana), sycamore (Platanus occidentalis), black gum (Nyssa sylvatica), black willow (Salix nigra), tag alder (Alnus serrulata), silky dogwood (Cornus amomum), and buttonbush (Cephalanthus occidentalis). Planting will be done at a density to achieve the vegetative success criteria further described in the Mitigation Banking Instrument. 4.2 Monitoring Requirements Stream stability and vegetation survival will be monitored across both the restoration and enhancement areas of the site to determine the success of the stream and buffer mitigation. Stream stability will be monitored with cross section surveys and visual assessment stream walks. Vegetation survival rates will be monitored using vegetation plots over approximately two percent of the planted area. The monitoring schedule and frequency proposed for the Bank will include annual assessments for a minimum of 7 years. Reports will be submitted to the USACE by April 1s' of each year. 4.2.1 Wetland Monitoring Requirements Wetland hydrology will be monitored to document hydric conditions in the wetland restoration areas. This will be accomplished with automatic recording pressure transducer gauges installed in representative locations across the restoration areas and reference wetland. The gauges will be downloaded quarterly and wetland hydroperiods will be calculated during the growing season. Gauge installation will follow current USACE guidance. Visual observations of primary and secondary wetland hydrology indicators will also be recorded during quarterly site visits. Hopkins Farm Mitigation Bank SAW-2023-01803 Page 16 of 75 5. Bank Establishment and Operation 5.1 Proposed Credit Types Expected credit types are Stream Mitigation Credits (SMCs) and Wetland Mitigation Credits (WMCs). Warm water stream mitigation credits will be generated through Restoration and Enhancement Level I (Table 5.1). Riparian, riverine wetlands mitigation credits will be generated through Restoration (both Re- establishment and Rehabilitation) and Enhancement activities (Table 5.2). The mitigation concept is illustrated in Figures 14A and 146.

The initial credit release will be based on the proposed restoration lengths (SMCs) and acreages (WMCs). The credit ledger will be managed by Hopkins Farm and approved by the District. The estimated credits will be released following District guidance, as shown in Table 5.3 below. For streams, 10% of credits will be withheld until four (4) bankfull events, in separate monitoring years, have been documented. Bank establishment shall include approval of mitigation banking instrument, approval of final mitigation plan, securing the Bank, financial assurances delivery, long-term protection mechanism delivery, title opinion delivery, and issuance of any permits necessary for construction.

Hopkins Farm has begun the process of securing coverage for the Bank. Details will be finalized prior to completion of the Mitigation Bank Instrument. The performance bond will be submitted for review and approval by Office of Counsel. The Corps will hold the original policy document. 5.4 Long -Term Management The Bank will be protected in perpetuity by conservation easements that extend at least 75 feet from the top of bank (edge of channel) and encompass all wetland areas. The responsible party for long-term management has not yet been chosen but will be secured prior to publishing the Mitigation Plan. Financial assurances for long-term management will be approved by the IRT prior to the commencement of any Bank establishment activities. Hopkins Farm Mitigation Bank SAW-2023-01803 Page 19 of 75 6.

The project site is located off Byrds Sawmill Road in Jericho, Caswell County, NC. Ground Truth Soil Consulting, PLLC (Ground Truth) has been retained to perform a Hydric Soil Investigation to describe and classify the soil on the basis of its present and/or past hydric status. The project site consisted of a mix of pasture and wooded areas of an active cattle farm. The topography consisted of gently rolling hills and generally narrow drainageways. The evaluation focused mainly in drainageways, depressions, and existing stream channels. METHODOLOGY Prior to performing the evaluation, NRCS soils maps, USGS topographic maps, and the previous hydric soil reports were reviewed. The field investigation was performed on September 23, 2020 by John C. Roberts, LSS. Soil borings were advanced via a hand auger and evaluated under moist conditions using procedures listed in the Field bookfor Describing and Sampling Soils, Version 3.0. Soil color was determined using a Munsell Soil Color Chart. Observations of the landscape as well as soil properties (depth, texture, structure, wetness, restrictive horizons, etc.) were recorded. Hydric soil status is based upon the NRCS Field Indicators of Hydric Soils in the Unities States - A Guide for Identifying and Delineating Hydric Soils (Version 8.2, 2018). Soil wetland mitigation potential was determined based upon evidence of past and present hydric soil conditions. The limits of the hydric soil areas were general identified via soil borings and topography. RESULTS Seventy-five (75) borings were advanced throughout the study area and placed into one of the two categories below. Hydric - Hydric soils within the study area showed some manipulation from past agricultural and timbering practices. The areas showing the greatest manipulation and soil degradation were observed in areas open to cattle traffic. The majority of the hydric soils were identified within drainageways, depressions, and riparian areas and dominated by soils that exhibited the F3 hydric soil indicator, which is defined as follows: F3. Depleted Matrix. A layer that has a depleted matrix with 60 percent or more, chroma of 2 or less and that has a minimum thickness of either: a. 5 cm (2 inches) if the 5 cm starts at a depth <10 cm (4 inches) from the soil surface, or b. 15 cm (6 inches), starting at a depth <_25 cm (10 inches) from the soil surface. A representative soil profile description is appended. These soils are most strongly associated with the Bannister soil series. Hopkins Farm Mitigation Bank SAW-2023-01803 Page 70 of 75 Somewhat Poorly Drained - Soils showing characteristics indicative of a Somewhat Poorly Drained drainage class were mapped and are shown in the attached figures. These soils generally occurred in upper reaches of headwater streams and along incised stream systems. The soils appear to be wet for a sufficient period for soil wetness characteristics to develop in the form of redoximorphic concentrations, Mn oxides, and oxidized root channels. These characteristics were noted beginning 6 to 10 inches from the existing soil surface. These areas likely represent areas of historically wetter soil moisture regimes where wetlands would typically be located. A typical soil profile description is appended. These soils do not fall into any specific soil series. CONCLUSION The study area has been degraded by past and present timbering/agricultural practices, in particular cattle production, and this is reflected in the degraded riparian areas. The identified hydric soil units are prime candidates for wetland enhancement by amending the site with native wetland vegetation and restoring the hydrology by raising the existing stream beds. It is anticipated that wetland enhancement will result from effectively establishing native wetland vegetation and restoring hydrology via elevating and stabilizing the existing stream. Areas of SWPD soils will benefit from the restored hydrology and could likely be reclassified as hydric. The findings presented herein represent Ground Truth's professional opinion based on our Hydric Soil Investigation and knowledge of the current regulations regarding wetland mitigation in North Carolina and national criteria for determining hydric soil.
