Wildlands Holdings X, LLC is managed by Wildlands Engineering, Inc. ( “Wildlands”) and was developed for the sole purpose of holding mitigation banks. The first site developed for the Bank will be the Dirty Boots Phase II Mitigation Site (“Site”) which will include work on Dirty Boots Creek and one unnamed tributary to Dirty Boots Creek in Chatham County, NC. The purpose of the Bank is to provide stream and wetland mitigation credits to compensate for impacts to Waters of the United States and/or State Waters within the service area, Hydrologic Unit 03030003 (Cape Fear 03), as depicted in Figure 1. The resulting conservation easement is estimated to be 9.7 acres. 1.0 Mitigation Bank Introduction and Objectives 1.1 Introduction The Dirty Boots Phase II Mitigation Site being established under the proposed Bank is located on an active cattle farm. In addition to Dirty Boots Creek, the Site contains an unnamed tributary to Dirty Boots that, for the purpose of this project, is referred to as UT1. The Site is located in the DWR Subbasin 03-06-12. All project streams flow to Bear Creek, which is classified as a Class C water. A review of historic aerials from 1950 to 2021 shows the Site streams have existed in their approximate locations over time. Even the forested areas are virtually the same. The eastern side of Dirty Boots Creek Reaches 1-3 was cleared of trees between 1950 and 1961 and has remained so since then. Current land use at the Site is a mix of agriculture, including active cattle, forestry, and hay pasture. Across the Site, approximately 30 head of cattle are currently managed. The majority of the property has been in cattle or hay pasture since about the 1970s. Within the project area, the streams are mostly eroding, alternatingly incised, and severely impacted by livestock access. Wetlands have been degraded due to channel incision, tree clearing, and livestock access. Some stream length is less incised and eroded but still accessed by livestock. The wetlands on the site have been primarily cleared and trampled by livestock. The Sponsor proposes to restore 1,135 linear feet (LF), enhance 820 LF, and preserve 586 LF of the site streams. The Sponsor proposes to rehabilitate 2.04 wetland acres and enhance 1.9 wetland acres. This stream and wetland mitigation will include a conservation easement area that is estimated to total 9.7 acres. An Interagency Review Team Draft Prospectus site walk was conducted on May 4, 2023. Several changes to the Draft Prospectus were recommended during that meeting and are reflected in this Final Prospectus. The main changes were the elimination of one crossing and the change in credit type of Dirty Boots Reach 3 from enhancement II to enhancement 1. A narrow upland buffer was also added to the edge of the wetland credit area on the east side of the easement. 1.2 Bank Location The proposed Bank (35.640582° N, 79.425046° W) is in western Chatham County approximately five miles southeast of Siler City (Figure 1, Figure 2). The site is located within the Hydrologic Unit Code (HUC) 03030003070020 and DWR Subbasin 03-06-12. The project site drains to Bear Creek which drains to the Rocky River and eventually to the Deep River. To get to the Site from Raleigh, NC take I-40 West to US-1 South. Follow US-1 to US-421 North in Sanford. Follow US-421 North for 17 miles to Elmer Moore Road. Go left on Elmer Moore Road, follow it 1.8 miles, go left on Bonlee Road for 0.4 miles and then right on Edwards Hill Church Road. The site is 0.3 miles on the left (downstream) and right (upstream). Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 2 1.3 Goals and Objectives The proposed Bank described above will provide numerous ecological benefits within the Cape Fear River Basin. Project benefits include site specific improvements and watershed scale benefits. The project goals and related objectives are described in Table 1. Project goals are desired project outcomes and objectives are activities that will result in the accomplishment of goals. The project will be monitored after construction to demonstrate success. A detailed monitoring program will be described in the forthcoming mitigation plan. Table 1. Mitigation Goals and Objectives Goal Objective Expected Outcomes Exclude livestock from streams and wetlands. Remove livestock from site or install livestock exclusion fencing along the conservation easement. Reduce sediment, turbidity, nutrient, and fecal coliform bacteria inputs. Improve stream channel stability. Construct stream channels that will maintain stable cross-sections, patterns, and profiles over time. Repair eroding stream banks with bioengineering. Reduce shear stress on channel boundary. Reduce sediment inputs from bank erosion. Improve instream habitat. Install habitat features such as constructed riffles, cover logs, and brush toes in restored/enhanced streams. Add woody materials to channel beds. Construct pools of varying depth. Increase and diversify available habitats for macroinvertebrates, fish, and amphibians, leading to colonization and an increase in biodiversity over time. Add complexity including large woody debris (LWD) to the streams. Reconnect channels with floodplains. Construct stream channels with appropriate bankfull dimensions and depth relative to the existing floodplain. Allow more frequent flood flows to disperse on the floodplain. Support geomorphology and higher-level functions. Improve wetland hydrology. Restore wetland hydrology, soils, and plant communities. Restore riparian wetlands and associated soil structure by raising stream beds, plugging existing ditches, removing livestock impacts, and planting native wetland species. Raise local groundwater elevations. Periodically inundate floodplain wetlands and vernal pools. Restore and enhance native floodplain and streambank vegetation. Plant native canopy and understory species in riparian zone and plant native shrub and herbaceous species on streambanks. Treat invasive species within the project area. Reduce sediment inputs from bank erosion and runoff. Increase nutrient cycling and storage in floodplain. Provide riparian habitat. Add a source of LWD and organic material to streams. Support all stream functions. Permanently protect the project from harmful uses. Establish a conservation easement on the Bank. Protect Bank from encroachment on the riparian corridor and direct impact to streams and wetlands. Support all stream functions. 1.4 Qualifications of Bank Sponsor The Sponsor, which is managed by Wildlands, was developed for the sole purpose of holding mitigation banks. Wildlands is a multidisciplinary professional engineering firm that brings together the expertise necessary to create outstanding ecological restoration projects in a timely and cost-effective manner.

Upon completion of the review process for the bank prospectus, the Sponsor will submit a detailed mitigation plan and an umbrella mitigation banking instrument (UMBI) for the site. The UMBI will provide detailed information regarding bank operation and the long-term management of the Bank. Once the final mitigation plan is approved and the accompanying instrument executed by members of the Interagency Review Team (IRT), the Sponsor will record a conservation easement on the Bank. 2.2 Landowner Information Table 2 lists the landowner’s name, parcel identification number(s), deed book number, page number, and address associated with the parcel on the site. Table 2. Landowner Information Landowner Parcel ID Number Deed Book and Page Number Address Eddie Hancock Watkins 0005034 DB: 2298, PG: 0197 PO Box 80 Bonlee, NC 27213 2.3 Proposed Service Area The Bank will be established to mitigate impacts to Waters of the United States and/or State Waters within the service area depicted in Figure 1. This service area includes Cape Fear 03 (Hydrologic Unit 03030003) and the cities of Pittsboro, Siler City, Asheboro, and parts of Greensboro. 2.4 Need and Feasibility of Mitigation Bank 2.4.1 Need Basinwide The Cape Fear 03 basin, as described in the DWR 2005 Cape Fear River Basin Water Quality Plan (WQP), contains significant development in and around the municipalities mentioned above. Several federal and state highways run through the basin including US-64, NC-87, I-85, and I-40. Developing a mitigation bank will allow unavoidable impacts to Waters of the United States within the service area to be mitigated appropriately and provide a means for the economic growth of this region to continue while ensuring aquatic resources and water quality are maintained. This includes the potential widening for the roads within the watershed. The Sponsor expects Bank customers to include private enterprises and public entities with North Carolina Division of Transportation (NCDOT) as the primary client. Figure 3 depicts the potential projects Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 4 set forth by NCDOT for fiscal years 2020-2029 within the Cape Fear 03 watershed. This includes transportation projects along several state, regional, and transition highways. Two megasites, the Chatham-Siler City Advanced Manufacturing Site and the Greensboro-Randolph Mega Site are being developed and will need stream and wetland mitigation credits. Local Subbasin The proposed Bank is located in DWR subbasin 03-06-12 and HUC 003030003070050. The Site includes an unnamed stream that will be called Dirty Boots Creek. Dirty Boots Creek flows into Bear Creek, the Rocky River, and eventually the Deep River. Another unnamed tributary flows into Dirty Boots Creek and will be called UT1 for this project. This Site is immediately upstream of an existing DMS full delivery project, Dirty Boots Phase I, that was initiated in 2022. The Site is located within the Division of Water Resources (DWR) Subbasin 03-06-12. The site is also located in the planning area for the Upper and Middle Rocky River Local Watershed Plan (LWP). The Site is upstream of the Bear Creek (Chatham) Aquatic Habitat, a Significant Natural Heritage Area that is located at the confluence of Bear Creek and Sandy Branch (Figure 2). The Bear Creek Aquatic Habitat flows directly into the Upper Rocky River Aquatic Habitat, which flows to the Lower Rocky River/Lower Deep River Aquatic Habitat. Implementation of this project will address the Cape Fear 03 CU-wide coals and the LWP goals by including the restoration of riparian buffers, stream restoration, wetland restoration, and livestock exclusion to improve stream and terrestrial habitats. Hydrologic functions will be improved through the reconnection of streams to their historic floodplains and re-establishment and rehabilitation of project wetlands. These restoration activities will enhance the Site’s ability to retain and remove nutrients and cattle waste from adjacent upstream sources before they can be transported downstream into the Bear Creek Aquatic Habitat and the Critical Habitat area of the Cape Fear shiner (Notropis mekistocholas) on the Rocky River and the Deep River. The watershed for Dirty Boots Creek is comprised of agriculture/pasture, forestland, and developed land (60%, 27%, and 13% respectively). The UT1 drainage area consists of forest and agriculture/pasture (81% and 19% respectively). 2.4.2 Feasibility A Radius Map Report was ordered for the Bank through Environmental Data Resources, Inc. (EDR) and obtained on April 11, 2022. No target properties, nor adjacent landowner properties, were listed in any of the Federal, State, or Tribal environmental databases searched by EDR. A summary of the EDR report is included in the appendix. The Bank is located in a rural watershed where the dominant land uses are agriculture, forest, and residential. The site is located near Siler City which could develop in the future as Chatham County grows. Future changes in land use might alter the watershed but it is likely that low density residential use would cause minimal change to site hydrology. Based on the preliminary existing conditions assessments performed at the Bank in 2022, Wildlands is confident that the site has substantial potential for the development of a viable mitigation bank. The project will provide substantial uplift to the Rocky River watershed and the Cape Fear River Basin. Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 5 3.0 Ecological Suitability of Site 3.1 Bank Site Characterization The Bank Site is currently maintained for livestock pasture with sparsely wooded buffers along the project streams. The Site is a livestock operation with approximately 30 head of free-range beef cattle. Cattle have access to pastures and streams. Pastures are fertilized most years during spring or fall and livestock waste is left to break down in place on pastures. Most of the streams and wetlands on site have been heavily impacted by livestock access. The existing conditions of Bank streams are described in Section 3.1.1, existing wetlands are described in Section 3.1.2, and existing vegetation is described in Section 3.1.3. The appendix contains stream determination forms and stream geomorphic data. Figure 4 is a topographic map of the site, Figure 5 illustrates the existing Site conditions, and Figure 6 is a map of the project stream watersheds. 3.1.1 Existing Conditions - Streams Dirty Boots Creek Dirty Boots flows from north to south onto the Site. Reach 1 begins at a headcut and the property line. The channel banks are incised and intermittently unstable, with some having vegetation. The stream is disconnected with its floodplain and current and historic cattle impacts are present. The floodplain wetlands are experiencing a drainage effect. Reach 2 continues south through a wooded area. There is evidence of channelization. And toe of slope seepage on both sides of the floodplain augments hydrology. Reach 3 has lower bank heights because two existing culverts (farm road and Edwards Hill Church Road) serve as downstream grade control. Areas of bank instability and erosion are evident. A 100-foot utility easement marks the downstream end of the reach. Reach 4 is primarily stable with limited areas of erosion and incision on both sides of Edwards Hill Church Road. Bank heights are typically low and habitat features are embedded but appear to be providing function. The stream is backwatered at the end of the reach at the property line due to a debris jam caused by a fence across the creek. UT1 UT1 Reach 1 is a short perennial reach that flows through a farm pond and drains east to Dirty Boots Creek. It is a small, functioning channel with low bank heights, low to moderate channel incision, and a stable profile. UT1 Reach 2 starts at a headcut where the channel becomes incised and moderately unstable until its confluence with Dirty Boots. Cattle are actively accessing UT1. 3.1.2 Existing Wetlands Existing wetlands and partially drained wetlands or hydric soil areas occur within the riparian zones of Dirty Boots Creek as well as along the lower portions of UT1. Wetland functions are impaired in these areas to varying degrees. A hydric soil delineation was conducted on April 21, 2022 by a Licensed Soil Scientist (LSS). The boundaries of the hydric soil delineation are shown in the LSS report in the Appendix. Dirty Boots Reach 1 UT1 Reach 2 Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 6 Generally, hydric soils are located within the active floodplain of Dirty Boots. There are also hillside seep inputs that serve to wet hillside soils, especially along the eastern side of Dirty Boots. In some areas, because of the productive hillside discharge, the hydric soils extend 6 to 8 feet in elevation above the top of the bank of Dirty Boots. This is primarily a wooded wetland area that is partially drained by the incised channels and cattle paths that funnel surface flow directly to the stream. Forested areas are dominated by red maple, willow oak, river birch and tulip poplar. Many of the mature trees are heavily buttressed, providing evidence of historic inundation. In addition to the wooded area, this wetland covers portions of the open pasture along the left bank of Dirty Boots. Pasture areas are dominated by a mix of wetland sedges and rushes with a mix of pasture grasses and tall fescue on ridges within the microtopography. Hydric soils were delineated within the majority of the proposed easement and extended beyond the boundary in many cases. 3.1.3 Existing Vegetation The condition of the riparian buffer along project streams varies throughout the site. Dirty Boots Reaches 1, 2, and 3 and UT1 have healthy riparian buffers from the upstream origin of the project downstream to the existing power line right of way. The overstory is composed of mixed oaks, tulip poplar (Liriodendron tulipifera) and river birch (Betula nigra) with smaller amount of red maple (Acer rubrum) and sweet gum (Liquidambar styraciflua). Scattered loblolly pine (Pinus taeda) are found at the higher elevations. The riparian buffer along UT1 can be described in the same way as Dirty Boots as it is in the same forested area. The eastern side of the proposed easement along the headwaters of Dirty Boots has some areas of open pasture without a consistent forested buffer. Much of this area is composed of partially drained wetlands dominated by various wetland sedges and rushes with occasional pasture grasses. Evidence of recent cattle grazing was noted in these areas. 3.1.4 Soils The floodplain areas of the proposed project are mapped by the Chatham County Soil Survey as primarily a Cid-Ligum complex (Figure 7). This complex transitions from a silt loam to a silt clay loam with depth before reaching first a consolidated bedrock layer and then unconsolidated bedrock layer. This series often contains inclusions of Wehadkee, which were identified during soil mapping exercises. Cid-Ligum and Wehadkee are listed on the National Hydric Soil list. The upstream portions of all the project tributaries are located in the Cid silt loam or Callison-Lignum mapping units. These moderately well drained soil types have very high runoff characteristics but are well suited to planting hardwood tree species. Table 3. Project Soil Type and Description Soil Name Description Cid-Lignum Complex Generally found in interfluves. Moderately to well drained with bedrock layer 20-60 inches deep. Cid Moderately well drained soil generally found summit or interfluves, Wehadkee inclusions often found in floodplains. Callison-Lignum Complex Like Cid, a moderately well drained soil generally found summit or interfluves, Wehadkee inclusions often found in floodplains. Wehadkee Poorly drained hydric soil, found in active floodplains. Inclusion to Cid Lignum.

The archaeological site files at the North Carolina Office of State Archaeology (OSA) have not been reviewed at this time. All appropriate cultural resource agencies will be contacted for their review and comment prior to any land disturbing activity. Several registered Natural Heritage and Managed Areas located within two miles include the Ore Hill (Exceptional Rating), Rocky River Subbasin Riparian Aquatic Habitat Area (Exceptional), the Knoll Ridge (Moderate Rating), a Foothills Land Conservancy Easement, a NC Land and Water Fund Project, and Triangle Land Conservancy Easements. 3.3 Threatened and Endangered Species Wildlands searched the USFWS and North Carolina Natural Heritage Program (NHP) databases to identify federally listed threatened and endangered plant and animal species for Chatham County, NC. Table F.6 details the current list of threatened and endangered species for Chatham County. Additionally, two species are listed as proposed endangered: the tricolored bat (Perimyotis subflavus) (TCB) and the green floater (Lasmigona subviridis). A cursory pedestrian survey conducted on April 8, 2022 indicated that the project area does not provide suitable habitat for any of the listed species. Wildlands will conduct a full review for protected species upon award of the contract and will coordinate with USFWS and NCWRC as necessary based on that review. In anticipation of the final ruling for the TCB and the green floater, Wildlands will continue to monitor the listing status of the proposed species and the project team will re-initiate consultation with USFWS, as appropriate, in order to ensure ESA, Section 7 compliance. Table 4. Federally Protected Species in Chatham County, NC Species Federal Status Habitat Birds Red-cockaded woodpecker (Picoides borealis) Endangered Open pine woodlands and savannahs with large specimen trees. Little to no hardwoods. Flowering Plant Harperella (Ptilimnium nodosum) Endangered Inhabits seasonally flooded rocky streams on granite outcrops that are sheltered from rapidly moving water. Rough-leaved Loosestrife (Lysimachia aperulaefolia) Endangered Occurs in the ecotones or edges between longleaf pine uplands and pond pine pocosins on moist to seasonally saturated sands and on shallow organic soils overlaying sand. Clams Atlantic Pigtoe (Fusconaia masoni) Threatened Inhabits coarse sand and gravel in small creeks to large rivers with excellent water quality and silt free substrates. Fish Cape Fear shiner (Notropis mekistocholas) Endangered Inhabits streams and rivers with gravel, cobble, and boulder substrate. Found in slow pools, riffles, and runs. They are often found near water willow beds. Habitat information from the following website: https://ecos.fws.gov/ecp/report/species-listings-by-current-range- county?fips=37037 3.4 Floodplain Compliance The Site is represented on the Chatham County Flood Map 3710868800J. The Site is located within FEMA Zone X and has minimal associated flood risk. Project tributaries are not FEMA mapped and do Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 8 not have associated models. Wildlands will communicate with the local floodplain administrator in Chatham County to determine if a floodplain development permit is required. The project will be designed to avoid adverse floodplain impacts or hydrologic trespass on adjacent properties or local roads. 3.5 Site Constraints and Access One crossing is proposed at the Site to maintain landowner access to pastures and to acknowledge an existing utility corridor easement. The culvert at Crossing 1 will be designed with the restored stream bed profile to allow for aquatic organism passage. Crossings are summarized and numbered below in Table 5 and in Figure 8. The Draft Prospectus proposed two crossings. At the request of the IRT, Wildlands approached the landowner about reducing the number of crossings by co-locating the utility crossing with the landowner crossing. The landowner agreed to the change. Additionally, the landowner agreed to fence out livestock from the pond and spillway area to the west of UT1. The fence will tie into the easement fence on the southern side of UT1 and extend to the west around the pond and tie-in to existing pasture fence, Table 5. Proposed Easement Crossings No. Width (ft) Location Internal or External Crossing Type Purpose 1 100 Dirty Boots – Reach 3 External Utility Corridor – New Culvert Utility Crossing – Landowner Crossing The easement boundaries around streams proposed for mitigation credit provide the required 50-foot minimum riparian buffer for Piedmont streams and extend well beyond the required 50-feet in areas. The entire easement area can be accessed for construction, monitoring, and long-term stewardship from Edwards Hill Church Road. The Brooks Field Airport and the Siler City Municipal Airport are located approximately 4 miles and 6 miles from the Site respectively. 4.0 Mitigation Work Plan Wildlands will begin the project by identifying the best design approach to meet the stated project objectives and implement the appropriate degree of intervention. A combination of analog, empirical, and analytical design approaches will potentially be used. All project resources will be designed to create stable, functional stream channels and riparian wetlands. 4.1 Stream Restoration All project reaches are proposed for restoration with the exception of Dirty Boots Reaches 3 and 4, and UT1 Reach 1. The restoration reaches will be designed and built with appropriate dimension, pattern, and profile to allow for frequent overbank flooding, provide stable bank slopes, enable biological lift, and reconnect streams with existing floodplains. Reference streams will be identified and will serve as one of the primary sources of information on which restoration designs are based. Wildlands has developed a general approach to be used as the basis for stream restoration design. The design approach, which is tailored to each site, continues to develop as additional projects are implemented. Sandy Branch Mitigation Site Designed and Constructed by Wildlands Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 9 All reaches are proposed for restoration designed with a Priority 1 approach, raising channel beds to reconnect them with existing floodplains. Livestock will be excluded from the proposed project area. Stream structures will be installed to promote water quality, stabilize the bed and banks, provide bedform diversity, and increase aquatic and terrestrial habitat. Wildlands plans to evaluate stream substrate and determine appropriate gradations/bed features for the Site streams. At this stage, Wildlands believes most of these channels will be built using a threshold channel approach with a gravel substrate. Wildlands believes based on other work in this area that appropriate substrate will be able to be harvested on-site. 4.2 Stream Enhancement I and II Dirty Boots Reach 3 is slated for an Enhancement I approach. In general, this reach is geomorphically stable but shows evidence of regular bank instability that will require intervention in the form of bank grading, grade control installation and targeted structure placement. Dirty Boots Reach 3 will also be enhanced by excluding cattle and providing buffer plantings (predominately on the left bank floodplain). This EI is proposed at a 1.5:1 credit ratio. UT1 Reach 1 is proposed for Enhancement II. This reach is primarily stable but will require targeted bank stabilization. This reach in its current condition has lower bank height ratios, low bank slopes, and a lesser degree of bank erosion than reaches slated for restoration and enhancement 1. The riparian buffer for UT1 Reach 1 is relatively healthy and contains a mature canopy. Exclusion of cattle, including the upstream pond, understory plantings, and targeted bank work is the justification of a 3:1 EII ratio for UT1 Reach 1. Although the density of invasive species in these two reaches is low, they will be treated. 4.3 Stream Preservation Dirty Boots Reach 4 will be preserved by treating invasive species and providing long-term protection through a conservation easement. 4.4 Wetlands Three activities will be used to improve wetland hydrology to justify wetland rehabilitation in the areas identified in Figure 8. First, cattle paths serving to funnel overland flow directly to receiving streams will be removed to enhance floodplain storage. Second, in areas of active pasture, re-establishment of soil structure will be improved through ripping and scarification of surface soils. This will break up compaction and encourage infiltration and subsurface discharge to project streams. Third, and likely most relevant, the restoration of incised streams using Priority 1 techniques will serve to effectively change the subsurface flow gradient and discharge characteristics of the groundwater table to the receiving stream. Tree planting and invasive species treatment will also occur in these areas to establish a healthy riparian wetland buffer. In areas that currently qualify as jurisdictional wetlands that are located adjacent to streams that are not incised, wetland enhancement activities will occur. This will include fencing out livestock, planting, invasive species treatment, and modification of compacted soils, if necessary. Wildlands will provide a 10-foot buffer between wetland enhancement areas and the cattle pasture to the east. Wetland rehabilitation areas will be located in areas of jurisdictional wetlands where a suite of wetland functions have been degraded. Rehabilitation would typically be in areas where floodplain drainage has been altered through channel incision or in areas where the floodplain drainage has been altered by cattle damage or ditching to accelerate surface water runoff to the receiving streams. The Site includes areas of wetland rehabilitation and enhancement. Because some of the wetland rehabilitation areas are located in forested areas, the overall credit ratio is proposed at 2:1. Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 10 Rehabilitation areas are adjacent to streams that will be restored from an incised condition using a Priority 1 restoration approach. Wetland enhancement is also proposed at a 2:1 ratio. 4.5 Vegetation Plan Native riparian buffers will be planted along restored and enhanced stream reaches, in all proposed wetland restoration zones, and in all riparian restoration areas. The ecological uplift can be summarized as transforming an agriculturally impacted area into a protected riparian corridor. Buffer restoration will involve planting appropriate native tree species along the riparian corridor. Herbaceous riparian vegetation will also be planted, but additional herbaceous plants are expected to re-establish naturally and through the placement of a native seed mix in disturbed areas. Live stake shrub species will be planted along restored streams. Vegetation management and herbicide applications will be needed over the first few years of tree establishment in the riparian buffer restoration areas to prevent encroachment of invasive species. Portions of the site that have been maintained as cleared agricultural fields will require little site preparation other than select herbicide treatments or limited mechanical clearing to remove undesirable underbrush prior to planting. The planting plan will be based on an appropriate nearby reference community and past project experience. The plan will be developed to restore appropriate strata (canopy, understory, shrub, and herbaceous layers). Vegetation planted in restored wetland areas will be based on species identified within appropriate reference locations and professional experience based on site conditions. Areas with an existing wooded riparian corridor will be treated for invasive species. The Site will be protected in perpetuity under a conservation easement and will be marked per IRT guidelines. 5.0 Determination of Mitigation Credits The mitigation stream and wetland credit calculations were derived using the US Army Corps of Engineers’ Stream Mitigation Guidance and was based on Wildlands’ conceptual design for maximum ecological uplift. Given the existing conditions of the stream channels, wetlands, the disturbance factors, and the constraints, management objectives for each reach have been established. The Site will be a combination of stream restoration and enhancement level I and II activities. Stream restoration is proposed at a ratio of 1:1, enhancement level I is proposed at 1.5:1 and enhancement level II is proposed at a ratio of 3:1 as listed below. In general, if enhancement level II areas are located within wooded areas with minimal opportunity for vegetative uplift but cattle have access and limited stream work is required, the 3:1 ratio is proposed. Stream preservation is proposed at a 10:1 ratio. The management objective, the mitigation type, and proposed amount of mitigation is presented in the below in Table 6.

Under no circumstances shall the Bank be debited until the necessary Department of Army (DA) authorization has been received for its construction or the District Engineer (DE) has otherwise provided written approval for the project in the case where no DA authorization is required for construction of the mitigation project. The DE, in consultation with the IRT, will determine if performance standards have been satisfied sufficiently to meet the requirements of the release schedules below. In cases where some performance standards have not been met, credits may still be released depending on the specifics of the case. Monitoring may be required to restart or be extended, depending on the extent to which the site fails to meet the specified performance standard. The release of project credits will follow Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 12 the Monitoring Requirements and Performance Standards for Compensatory Mitigation in North Carolina, dated February 9, 2013. The proposed credit release schedule is shown in Tables 8 and 9. Table 8.

The initial allocation can be released without prior written approval of the DE upon satisfactory completion of the following activities: a. Execution of the UMBI by the Sponsor and the USACE. b. Approval of the final mitigation plan. c. Recordation of the conservation easement and delivery of a title opinion acceptable to the USACE. d. Delivery of the financial assurances described in the mitigation plan. e. 404 permit verification for construction of the site, if required. f. Documentation of the establishment of the long term/endowment/escrow account. 5.3 Subsequent Credit Releases All subsequent credit releases must be approved by the DE, in consultation with the IRT, based on a determination that required performance standards have been achieved. For stream projects, a reserve of 10% of a site’s total stream credits shall be released after four bankfull events have occurred in separate years, provided the channel is stable and all other performance standards are met. In the event that less than four bankfull events occur during the monitoring period, release of these reserve credits shall be at the discretion of the IRT. As the bank approaches milestones associated with the credit release, Wildlands will submit a request for credit release to the DE along with documentation substantiating achievement of criteria required for release to occur. This documentation will be included with the annual monitoring report. 6.0 Performance Standards and Monitoring Plan The performance criteria for the Site will follow approved performance criteria presented in the October 2016 IRT Mitigation Monitoring Guidance. Annual monitoring and semi-annual site visits will be conducted to assess the condition of the completed project. Specific performance standard components are proposed for stream morphology, hydrology, and vegetation. The stream restoration reaches of the project will be assigned specific performance criteria components for hydrology, vegetation, and geomorphology. The enhancement II reaches will be assigned specific performance criteria components for vegetation only. Performance criteria will be evaluated throughout the (up to) seven years of post- construction monitoring. If all stream, vegetation, and hydrologic performance criteria have been successfully met and at least four bankfull events have occurred during separate years, Wildlands may propose to terminate stream and/or vegetation monitoring after five years with written approval from the USACE and North Carolina Interagency Review Team (IRT). An outline of the performance criteria components follows. 6.1 Stream Morphological Parameters and Channel Stability Dimension Riffle cross sections on the restoration reaches should be stable and should show little change in bankfull area, bank height ratio, and width-to-depth ratio. Riffle cross sections should fall within the parameters defined for channels of the appropriate stream type. If any changes do occur, these changes will be evaluated to assess whether the stream channel is showing signs of instability. Changes in the channel that indicate a movement toward stability or enhanced habitat include a decrease in the width- to-depth ratio in meandering channels or an increase in pool depth. These sorts of bed changes do not constitute a problem or indicate a need for remedial actions. If channel changes indicate a movement toward stability, remedial action will not be taken. Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 14 In order to assess channel dimension performance, permanent cross sections will be installed on restoration and reaches per the IRT Mitigation Monitoring Guidelines (October 2016). Each cross section will be permanently marked with pins to establish its location. Cross section surveys will include points measured at all breaks in slope, including top of bank, bankfull, edge of water, and thalweg. Cross section and bank pin surveys (if applicable) will be conducted in monitoring years one, two, three, five, and seven. Profile and Pattern Longitudinal profile surveys will be conducted during the as-built survey but will not be conducted during the seven-year monitoring period unless other indicators during the annual monitoring indicate a trend toward vertical and lateral instability. If a longitudinal profile is deemed necessary, monitoring will follow standards as described in the Stream Channel Reference Sites: An Illustrated Guide to Field Technique (Harrelson et. al., 1994) for the necessary reaches. 6.2 Hydrology Stream Four bankfull flow events, occurring in separate years, must be documented on the restoration reaches within the seven-year monitoring period. Stream monitoring will continue until success criteria in the form of four bankfull events in separate years have been documented. Bankfull events will be documented using photographs and either a crest gage or a pressure transducer, as appropriate for Site conditions. The selected measurement device will be installed in the stream within a surveyed riffle cross section. Photographs will also be used to document the occurrence of debris lines and sediment deposition. Where restoration activities are proposed for intermittent streams, monitoring gages will be installed to track the frequency and duration of stream flow events. Continuous surface water flow within the tributaries must be documented to occur every year for at least 30 consecutive days during the seven- year monitoring period. This 30-day period of flow can occur at any point during the year. Additional monitoring may be required if surface water flow cannot be documented due to abnormally dry conditions. Wetland Groundwater monitoring will be conducted for seven years after construction to evaluate the hydrologic state of the restored wetland areas. Wetland groundwater gages will be installed in accordance with the techniques and standards described in the USACE document entitled “Technical Standard for Water- Table Monitoring of Potential Wetland Sites” (ERDC TN-WRAP-05-2, June 2005). Groundwater monitoring gages will be established throughout the wetland area to adequately characterize the different soils, vegetation communities, and surface topographic variations that are found across the site. According to Table 1 in the USACE Mitigation Guidance update, Wehadkee soils have a wetland saturation range of 12-16% of the growing season. Based on this, the final criteria for the wetland hydrology will be groundwater levels within 12 inches of the soil surface for a minimum period of 12% of the growing season. 6.3 Vegetation The final vegetative success criteria will be the survival of 210 planted stems per acre in the riparian corridors at the end of the required monitoring period (year seven). The interim measure of vegetative Example of a cross section survey Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 15 success for the Site will be the survival of at least 320 native species stems per acre at the end of the third monitoring year and at least 260 stems per acre at the end of the fifth year of monitoring. Also, trees must average seven feet in height at the end of the fifth monitoring year, and ten feet in height at the end of the seventh monitoring year. If this performance standard is met by year five and stem density is trending towards success (i.e., vigor), and invasive species are not threatening ecological success, monitoring of vegetation on the Site may be terminated with written approval by the USACE in consultation with the IRT. The extent of invasive species coverage will also be monitored and controlled as necessary throughout the required monitoring period. Vegetation monitoring quadrants will be installed across the Site to measure the survival of the planted trees. The number of monitoring quadrants required, and frequency of monitoring will be based on the October 2016 IRT Mitigation Monitoring Guidance. Vegetation monitoring will occur in the summer and will follow the CVS-EEP Protocol for Recording Vegetation (2008). 6.4 Other Parameters Photo Reference Stations Photographs should illustrate the Site’s vegetation and morphological stability on an annual basis. Cross section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal photos should indicate the absence of persistent mid-channel bars within the channel or vertical incision. Grade control structures should remain stable. Deposition of sediment on the bank side of vane arms is preferable. Maintenance of scour pools on the channel side of vane arms is expected. Photographs will be taken once a year to visually document stability for seven years following construction. Permanent markers will be established and located with GPS equipment, so that the same locations and view directions on the Site are photographed each year. Photos will be used to monitor restoration and enhancement areas, as well as vegetation plots. Longitudinal reference photos will be established at regular intervals along the channel by taking a photo looking upstream and downstream. Cross sectional photos will be taken of each permanent cross section looking upstream and downstream. Reference photos will also be taken for each of the vegetation plots. Representative digital photos of each permanent photo point, cross section, and vegetation plot will be taken when the stream and vegetation assessments are conducted. The photographer will make every effort to consistently maintain the same area in each photo over time. Visual Assessments Visual assessments should support the specific performance standards for each metric as described above. Visual assessments will be performed along stream reaches on a semi-annual basis during the seven-year monitoring period. Problem areas such as channel instability (e.g. lateral and/or vertical instability, instream structure failure/instability and/or piping, headcuts), vegetation health (e.g. low stem density, vegetation mortality, invasive species, or encroachment), beaver activity, or livestock access will be noted. Areas of concern will be mapped and photographed and will be accompanied by a written description in the annual report. Problem areas will be re-evaluated during each subsequent visual assessment. Should remedial actions be required, a plan of action will be provided in the annual monitoring report. Benthic Macroinvertebrates If required by DWR as part of the project’s permitting process, benthic macroinvertebrate sampling will be performed on the restored site. Any required sampling will be performed using DWR Standard Operating Procedures for Benthic Macroinvertebrates (October 2012). Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 16 7.0 Maintenance and Long-Term Sustainability 7.1 Maintenance The Bank shall be monitored on a regular basis and a physical inspection of the project shall be conducted at a minimum of once per year throughout the post-construction monitoring period until performance standards are met. These site inspections may identify site components and features that require routine maintenance. Routine maintenance will be conducted to rectify identified deficiencies and may include the activities listed in Table 10. Table 10. Maintenance Plan Component / Feature Maintenance through project close-out Stream Routine channel maintenance and repair activities may include chinking of in-stream structures to prevent piping, securing loose coir matting, and supplemental installations of live stakes and other target vegetation along the channel. Areas where stormwater and floodplain flows intercept the channel may also require maintenance to prevent bank failures and head- cutting. Beaver dams that inundate the streams channels shall be removed and the beaver shall be trapped. Vegetation Vegetation shall be maintained to ensure the health and vigor of the targeted community. Routine vegetation maintenance and repair activities may include supplemental planting, pruning, mulching, and fertilizing. Exotic invasive plant species affecting the viability of the mitigation shall be controlled by mechanical and/or chemical methods. Any vegetation control requiring herbicide application will be performed in accordance with the NC Department of Agriculture (NCDA) rules and regulations. Site Boundary Site boundaries shall be identified in the field to ensure clear distinction between the bank site and adjacent properties. Boundaries may be identified by fence, marker, bollard, post, tree- blazing, or other means as allowed by site conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as-needed basis. 7.2 Adaptive Management Upon completion of site construction, the Sponsor will implement the post-construction monitoring protocols and minor remedial actions (routine maintenance) will be performed as needed for the duration of the monitoring period. The Sponsor will notify the USACE immediately if monitoring results or visual observations suggest a trend towards instability, major remedial actions are needed, or that performance standards cannot be achieved. Should major remedial measures be required, the Sponsor will submit a Corrective Action Plan and coordinate with the USACE until authorization is secured to conduct the adaptive management activities. The Sponsor is responsible for funding and/or providing the services necessary to secure any necessary permits to support the proposed major remedial adaptive management actions, to implement the corrective action plan, and to deliver record drawings that depict the extent and nature of the work performed. If the USACE determines that the Bank is not meeting performance standards or the Sponsor is not complying with the terms of the instrument, the USACE may take appropriate actions, including but not limited to: suspending credit sales, utilizing financial assurances, and/or terminating the instrument. 7.3 Long Term Management Provisions The Sponsor will institute a Long Term Management Plan responsible for assessing the condition of the Bank and implementing maintenance provisions to maintain performance of the Bank. The proposed conservation easement will help to ensure that only IRT-allowable activities take place. This easement Widllands Cape Fear 03 Umbrella Mitigation Bank Dirty Boots Phase II Mitigation Site Final Prospectus Page 17 will be transferred to an IRT-approved non-profit organization once monitoring success criteria have been achieved. The provider for long term management of the sites is anticipated to be Unique Places to Save (UP2Save). UP2Save is a 501c3 nonprofit committed to land conservation through conservation planning and management. The funding mechanism for long term management will be a stewardship endowment funded by Wildlands. Contact information for UP2Save is listed below. Unique Places to Save 206 Causeway Drive #206 Wrightsville Beach, NC 28480 Phone: (910) 707-3622 Email: info@uniqueplacestosave.org To monitor the project’s continued success, a Long Term Management Plan will be implemented following the seven-year monitoring period. All components of the bank will be inspected annually or less frequently as needed to ensure that the Bank remains stable in perpetuity. Sources of instability or other deficiencies will be addressed. Invasive species will be managed annually or less frequently as needed to ensure the long-term survivability of the planned native vegetation community. All reporting will be documented and kept on file for future reference. 8.0 References Geologic Map of North Carolina 1:500,000 scale, 1985. Compiled by Philip M. Brown at el.
