Wildlands Holdings VI, LLC is wholly owned by Wildlands Engineering, Inc. (Wildlands). 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, 8-digit Hydrologic Unit Code 03030002 (Cape Fear 02), as depicted in Figure 1. The resulting conservation easement is estimated to be approximately 52 acres. 1.0 Mitigation Bank Introduction and Objectives 1.1 Introduction The Underdog Mitigation Site is located in Guilford County, NC, approximately five miles north of Liberty, NC (Figure 1). The project includes the restoration, enhancement, and preservation of streams and the re-establishment, enhancement, and preservation of wetlands. The Site is located within the Cape Fear River Basin 14-digit Hydrologic Unit Code (HUC) 03030002040080, is being submitted for mitigation credit in the Cape Fear River Basin Catalog Unit 03030002 (Cape Fear 02). The Site will protect up to 52 acres of aquatic resources and riparian area in a conservation easement. The Site is located within the Division of Water Resources (DWR) Subbasin 03-06-03. Within the project area, the streams are mostly eroded, alternatingly incised, and impacted by past land use practices. Wetlands have been degraded due primarily to channel incision. The Sponsor proposes to restore, enhance, and preserve 10,789 linear feet (LF) of the site streams and re-establish, enhance, and preserve 27.406 acres of riparian wetlands. 1.2 Bank Location The Site is located within the USGS 14-digit Hydrologic Unit Code (HUC) 03030002040080 and DWR Subbasin 03-06-03 (35.553873° N, 79.34674' W). The Site is situated east of Humble Road and is bisected Kimesville Road. The Site includes unnamed tributaries to South Prong Stinking Quarter Creek. The south and north prongs combine to form Stinking Quarter Creek approximately six miles downstream. Stinking Quarter Creek flows to Alamance Creek which flows into the Haw River downstream of Swepsonville. To get to the Site from Raleigh, NC take 1-64 West to US-421 North. Follow US-421 North to US-421 North in Sanford. Follow US-421 North for nine miles to Exit 180 (Old 421 Road) towards Liberty. Continue on Old 421 Road to Kimesville Road. Continue on Kimesville Road for eight miles to the Site. 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. �. Widllands Cape Fear 02 Umbrella Mitigation Bank W Underdog Mitigation Site — Draft Prospectus Page 1 Table 1.

The proposed service area is shown in Figure 2. The service area includes the cities of Greensboro, Burlington, and Chapel Hill and portions of Durham, Morrisville, Cary, Apex, and Pittsboro. 2.4 Need and Feasibility of Mitigation Bank 2.4.1 Need Basinwide The Cape Fear 02 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 and also has several large, registered agricultural operations. Several federal and state highways run through the basin including 1-40/85, US-29, US-70, US-220, US-421, NC-49, NC-54, NC-61, NC-62, and NC-87. 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. �. Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 3 The Sponsor expects Bank customers to include private enterprises and public entities with North Carolina Division of Transportation (NCDOT) as the primary client. Several mega sites including the Greensboro -Randolph Megasite in nearby Liberty and the Chatham-Siler City Megasite in Siler City will bring jobs and people to the area. Infrastructure and housing will likely be required to support these enterprises. Mitigation demand in this basin has been historically strong and is expected to continue, justifying establishment of additional mitigation sites and banks within the service area. Figure 3 depicts the potential projects set forth by NCDOT for fiscal years 2024-2033 within the Cape Fear 02 watershed. This includes transportation projects along several state, regional, and transition highways. If the DWR 2022 Cape Fear River Basin WQP is released before the mitigation plan submittal, Wildlands will update the basinwide need of a mitigation bank, accordingly. Loral Suhhasin The proposed Bank is located in DWR subbasin 03-06-03 and 14-digit HUC 03030002040080. The Site includes an unnamed tributary to South Prong Stinking Quarter Creek (referred to in this proposal as Britt Creek) and seven tributaries to Britt Creek. Land use within project stream watersheds is a mix of forested and agricultural land with some low - density residential development. The land use was calculated using the National Land Cover Database (NLCD) for 2011 available through StreamStats Version 4. The watershed areas and current land uses are shown on Figure 4a and 4b. 2.4.2 Feasibility Based on the preliminary existing conditions assessments performed at the Bank in early 2023, Wildlands is confident that the site has substantial potential for the development of a viable mitigation bank. The project will provide substantial uplift to South Prong of Stinking Quarter Creek and its receiving waters within the Cape Fear River Basin. 3.0 Ecological Suitability of Site 3.1 Bank Site Characterization The Site is located on five parcels owned by five landowners and surrounded by agricultural and forest land. Most of the Site is forest land characterized by mid to late successional forest canopy. The land around Britt Creek Reach 6 and Eric Branch is former cattle pasture that is currently used for hay production (Figure 5). Wildlands reviewed historic aerials from 1937 to present (Appendix A). Between 1937 and 1950 a mill pond is visible upstream of the existing, breached mill dam on Britt Creek. It appears to have impounded the creek to a point upstream of Jim Branch. The mill pond is no longer visible in the 1961 aerial and by 1964 Britt Creek can be seen flowing through the former impoundment. Other notable land use changes include the construction of a gas line across upper Britt Creek between 1961 and 1964 and conversion of forest to cattle pasture around lower Britt Creek between 1970 and 1977. Aside from these changes, land use appears to have been consistent since the 1930's and the streams have existed in their approximate locations over that time period. Photographs showing the existing condition of the Site are provided in Appendix B. Descriptions of project streams, wetlands, and riparian vegetation are included in the following sections and supporting data is provided in Appendix C. A USGS topographic map of the Site is provided in Figure 6. �. Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 4 3.1.1 Existing Conditions - Streams In February 2023, all Site streams were evaluated and scored. Britt Creek, Jim Branch, Alex Branch, Rob Branch, and Matt Branch scored as perennial. Eric Branch, Ben Branch, and Gerardo Branch scored as intermittent. Across the site, bed material consists of sand, gravel, and cobble with minimal LWD. Table 3 and the descriptions below detail the existing conditions of project streams. Table 3.

Rritt CrPPk Britt Creek generally flows northeast through the Site. Reach 1 flows from a culvert under Humble Road through a forested buffer approximately 50 feet wide with agricultural fields beyond. The floodplain is narrow and flat in this area with Chinese privet (Ligustrum sinense) and multiflora rose (Rosa multiflora) along both banks. The channel is incised, straightened and has been impacted by a utility crossing at the downstream end of the reach. �. Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site - Draft Prospectus Page 5 Reach 2 flows northeast through a mature hardwood forest with Chinese privet and multiflora rose in the understory of the upper end of the reach. Ben Branch and Jim Branch flow into this reach. Erosion is consistent throughout the reach. Incision is much greater downstream of a bedrock knickpoint within the reach. The bank height ratio was calculated as 1.6 in the surveyed cross section below the knickpoint. The reach has a moderately wide floodplain with moderate valley side slopes on either side. Some bedrock steps exist in the channel bed. Reach 3 starts at a 90-degree bend in the stream and flows east. An old mill dam that has been breached is located in the upper portion of the reach. The reach ends at an existing farm access road (ford). This reach has an established riparian buffer of mature hardwood species with areas of dense vines. The floodplain is narrow with steep valley walls on both sides of the stream. The channel bed contains a combination of small boulders and stones from the breached dam. Reach 4 starts downstream of the existing farm access road (ford). Rob Branch flows into the middle of this reach. Near the Rob Branch confluence, the stream has been relocated to allow drainage from manmade upland areas associated with the old mill dam. Some signs of streambank erosion and incision are present due to Reach 4 being beyond the old mill dam grade control influence. Similar to Reach 3, riparian buffer is established and mature. The floodplain is narrow with a steep valley wall on the Northern side of the stream. The Southern side of the stream contains Rob Branch and a few ditches draining the wider portion of floodplain. Historical relocation for upland drainage has formed a large, sandy depositional feature near the confluence with Rob Branch. Reach 5 starts downstream of the footprint of the old mill site and extends approximately 180 feet downstream of the confluence of Gerardo Branch. The reach is eroded in many locations along both banks. Cattle have historically had access to Reaches 5 and 6 and there is one highly eroded access point. The reach has a forested buffer that consists of mixed hardwood species along the right bank and little to no wooded riparian buffer along the left bank. The floodplain is narrow and widens slightly at the downstream end as valley slopes become more moderate. Reach 6 flows northeast to a culverted crossing under Kimesville Road and continues downstream. Eric Branch flows into Reach 6 upstream of Kimesville Road and Matt Branch flows into Reach 6 downstream of Kimesville Road. Reach 6 is incised and eroded throughout. The bank height ratio was measured at 1.5 — 2.1 in the surveyed cross sections. The valley is generally narrow along both banks with low to moderate grade slopes. Upstream of Kimesville Road, there is little to no riparian buffer on either side, with pasture grasses dominating the floodplain and occasional woody plants such as Chinese privet, river birch (Betula nigra), American sycamore, American holly, and red maple along the banks. Downstream of Kimesville Road, a forested buffer ranging from 20-100 feet wide, with pasture beyond, exists in the right floodplain and the left buffer area is completely forested. A large, high -quality wetland borders the left streambank at the downstream extents. Relic hydric soils are present throughout the floodplain. lim Rrnnrh Jim Branch flows southeast through the Site. Reach 1 begins downstream of Humble Road and flows through a mature forested buffer. The floodplain is narrow along both banks with moderate valley slopes. Bedrock near the middle of Jim Branch provides grade control for Reach 1. Reach 2 begins just upstream of the bedrock grade control. The floodplain is narrow and widens as the stream approaches the floodplain of Britt Creek. Valley slopes along both sides of this stream are moderately sloped. The channel is incised and eroded. The bank height ratio was measured at 2.3 in the surveyed cross section. 2-6 inch bedrock steps are present in the channel bed. �. Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 6 Alex Branch Alex Branch flows south and begins approximately 1,350 feet upstream of the Site. Reach 1 has a mature forested buffer over 200 feet wide. Valley wall slopes along both sides of this stream are moderate with a narrow floodplain. Reach 2 begins at an existing head -cut and flows into Jim Branch Reach 2. The stream is eroded and incised. Similar to Reach 1, Reach 2 has a mature forested buffer over 200 feet wide characterized by moderate valley wall slopes and a narrow floodplain. Ben Branch Ben Branch flows northwest into Britt Creek Reach 2. This stream divides cattle and agricultural fields, flowing through a forested buffer before entering the Site in the floodplain of Britt Creek. Valley walls along both sides of this stream are gently sloped with a narrow floodplain. The channel is incised. Cattle have historically had access to this channel upstream of the Site. Rob Branch Rob Branch flows north and drains from upstream cattle and agricultural fields. The stream has a mature forested buffer ranging from 20 to 100 feet on either bank. Reach 1 has a narrow floodplain with moderately sloped valley walls. Reach 2 has a narrow floodplain with moderately sloped valley walls that widens as the stream enters the floodplain of Britt Creek. The channel exhibits some bank erosion and drains potential wetland areas. Eric Branch Eric Branch flows north and enters the Site downstream of a culverted crossing under Kimesville Road. The valley walls are moderately to steeply sloped along the stream and broaden as the stream enters the floodplain of Britt Creek, where the stream appears to have been straightened and relocated to the valley edge. There is little to no riparian buffer on either side of the stream, with pasture grasses dominating the floodplain and occasional woody plants such as American sycamore (Platanus occidentlias), American holly (Ilex opaca), and red maple (Acer rubrum) along the banks. The stream is eroded and highly incised throughout. The bank height ratio was measured at 2.3 in the surveyed cross section. The stream receives runoff and sediment from Kimesville Road. Gerardo Branch Gerardo Branch flows north and drains from upstream cattle and agricultural fields. The stream has a mature forested buffer ranging from 40 to 50 feet at the upstream end that widens to over 300 feet as it approaches the floodplain of Britt Creek. The channel is primarily stable. Valley walls along both sides of the stream are moderately sloped with a narrow floodplain that widens as the stream approaches Britt Creek. Matt Branch Matt Branch originates west of Kimesville Road and flows southeast through a forested corridor towards Britt Creek. Matt Branch flows onto the Site through a culverted crossing beneath Kimesville Road. The downstream invert of this culvert is perched approximately 18-24 inches above the normal pool elevation of the downstream scour pool. The stream flows through the forested left buffer of Britt Creek Reach 5, exhibiting low bank height ratio and stable pattern. Upstream of the confluence with Britt Creek, the channel incises to match bed grade of Britt Creek at the confluence. 3.1.2 Existing Wetlands Existing jurisdictional wetlands along Britt Creek Reaches 1, 2, 4, and 5 and Jim Branch are impaired by the drainage influence of the incised stream channels and infrequent overbank events as well as project- Widllands Cape Fear 02 Umbrella Mitigation Bank W Underdog Mitigation Site — Draft Prospectus Page 7 wide ditching. Existing wetlands along Britt Creek Reach 1 and the upper portions of Britt Creek Reach 2 are further impaired by the presence of invasive species such as Chinese privet and multiflora rose and aggressively growing native species such as blackberry (Rubus pensilvanicus) and greenbrier (Smilax rotundifolia). These wetlands provide minimal functional value to wildlife habitat or water quality improvements. Hydroperiods are expected to be relatively short due to the effect of the incised stream channels and ditches. A Licensed Soil Scientist (LSS) confirmed the presence of hydric soil in all existing wetlands (Appendix D). There are additional areas containing hydric soils along all reaches of Britt Creek, Jim Branch, Ben Branch, Eric Branch, and Rob Branch which do not currently have wetland hydrology. This suggests the historic presence of wetlands that have been drained by stream incision and manipulation of the Site. 3.1.3 Existing Vegetation Riparian buffer conditions along project streams vary across the Site. Britt Creek Reach 1 has a forested buffer consisting primarily of young tree and shrub species along its banks. Britt Creek Reaches 2 and 3 meanders through a forested buffer varying in width from 50 to over 300. Reach 4 of Britt Creek has little to no wooded buffer along its left bank and Reach 5 has little to no wooded buffer along either bank. Upslope of the Site boundary, Ben Branch has a forested buffer between 30 to 50 feet wide with agricultural fields beyond. On site, Ben Branch flows through the wide forested buffer adjacent to Britt Creek. Both Alex Branch and Jim Branch have riparian buffers consisting of mature mixed hardwood forest that extend over 200 feet from both banks. Rob Branch and Gerardo Branch have similar buffer conditions to Ben Branch upslope of the Site boundary, with wider buffers (100-200 feet) existing nearer to the Site boundary. On site, Rob Branch and Gerardo Branch flow the forested Britt Creek floodplain. A higher percent composition of saplings exists along Gerardo Branch than the remainder of the Site. Eric Branch has little to no wooded buffer along either bank as it flows through an active hay field. Forested buffer zones consist of mixed hardwood forests which vary in composition across the Site. Common species include tulip poplar (Liriodendron tulipifera), American sycamore, winged elm (Ulmus alata), red maple, river birch, sweetgum (Liquidambarstyraciflua), American hornbeam (Carpinus caroliniana), box elder (Acer negundo), loblolly pine (Pinus taeda), American holly, American beech (Fagus grandifolia), and eastern red cedar (Juniperus virginiana). Invasive species such as Chinese privet, Japanese honeysuckle (Lonicera japonica), and multiflora rose can be found in most forested areas in variable densities but are not dominating native vegetation. In non -forested areas, pasture grasses dominate the floodplains with occasional occurrences of trees, shrubs, and vines along channel banks. 3.1.4 Soils The proposed project is mapped by the Web Soil Survey for Guilford County. The primary project area soils are described below in Table 4 and Figure 7. Wehadkee soils are mapped along streams with broader floodplains. Appling Sandy Loam, Cecil Sandy Loam, and Vance Sandy Loam soils are generally mapped on hillslopes and narrower valleys. A LSS performed on -site soil evaluations within areas proposed for wetland mitigation and determined that existing wetland hydric soils are most like the Wehadkee series and areas with relic hydric soils between 11-20 inches are most like the Chewacla series. The LSS report is included in Appendix D. Table 4. Project Soil Types and Descriptions �.

Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 9 3.2 Cultural Resources and Significant Natural Heritage Areas The Site is not located near any sites listed on the National Register with the State Historic Preservation Office (SHPO). 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. A breached mill pond dam is present within the Site boundary. 3.3 Threatened and Endangered Species Wildlands searched the U.S. Fish and Wildlife Service (USFWS) and North Carolina Natural Heritage Program (NHP) databases to identify federally listed threatened and endangered plant and animal species for Guilford County, NC. Currently the Cape Fear shiner (Notropis mekistocholas), the Roanoke logperch (Percina rex), and Schweinitz's sunflower (Helianthus schweinitzii) are listed as endangered and the Atlantic pigtoe (Fusconaia masoni) and small whorled pogonia (Isotria medeoloides) is listed as threatened. Pedestrian surveys conducted on February 14 and February 16, 2023, indicated that the project area does provide suitable habitat for the Atlantic pigtoe and small whorled pogonia. The Site does not provide suitable habitat for the Cape Fear shiner, Roanoke logperch, and Schweinitz's sunflower. Wildlands will conduct a full review for protected species during development of the Mitigation Plan and will coordinate with USFWS and NCWRC as necessary based on that review. Table S. Federally Protected Species in Chatham County, NC Species Federal Status Habitat Flowering Plant Schweinitz's sunflower Endangered Inhabits roadsides, power line clearings, old pastures, and (Helianthus schweinitzii) woodland clearings. It prefers poor clayey or rocky soils. Small whorled pogonia Inhabits open, somewhat dry, hardwood or mixed hardwood (Isotria medeoloides) Threatened and softwood forests, with scarce shrub and herb layers, small breaks in canopy. Clams Atlantic Pigtoe (Fusconaia Threatened Inhabits coarse sand and gravel in small creeks to large rivers masoni) with excellent water quality and silt free substrates.

They are often found near water willow beds. Roanoke logperch (Percina Endangered Inhabits medium to large warm -water streams and rivers of rex moderate gradients with unsilted substrates. Habitat information from the following website: https://ecos.fws.gov/ecp/report/species-listings-bv-current-range- countV?fips=37037 3.4 Floodplain Compliance Britt Creek is labeled South Prong Stinking Quarter Creek Tributary 1 and is mapped in a Zone AE Special Flood Hazard Area (SFHA) on Guilford County Flood Insurance Rate Map (FIRM) Panel 8728 (Appendix Q. A limited detailed study has been performed on Britt Creek with base flood elevations defined and a delineated floodplain. The tributaries do not have detailed hydraulic studies performed, but the downstream portions of all reaches confluent to Britt Creek fall within the SFHA. Effective hydraulic modeling for Britt Creek will be obtained from the NC Floodplain Mapping Program. A no -rise condition will be pursued if compatible with stream restoration and floodplain enhancement grading. If a no -rise condition is not attainable, then a CLOMR will be prepared. Wildlands' engineers have successfully �. Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 10 navigated the No -Rise and CLOMR processes for several similar full -delivery project sites. 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 Existing culverts beneath Humble Road and Kimesville Road provide minor constraints to the Site design as they will dictate channel bed grade and bankfull stage elevation within their vicinity. Visual inspection of these culverts indicates they are in good condition, and they are not proposed to be replaced or altered as part of the proposed project. Due to difference in elevation between the existing convert inverts and the floodplain, transitional sections of Priority II restoration and/or enhancement will be implemented within the vicinity of the culverts to provide floodplain access at the bankfull stage. An existing gas utility easement crossing the upstream end of Britt Creek Reach 2 provides another minor Site constraint. Visual inspection of the area within the crossing indicates Priority 1 restoration should be achievable through the existing easement. Wildlands will coordinate with the utility during Mitigation Plan development to ensure the proposed design does not conflict with the interests and/or requirements of the utility. Three external crossings are proposed at the Site to maintain landowner access to a pasture and avoid conflict with existing public right of way and utility easement. Proposed crossings will be maintained in the same position as the existing crossings. Proposed crossings are summarized and numbered below in Table 6 and on Figure 8. Table 6. Proposed Easement Crossings No. Width (ft) Location Internal or External Crossing Type Purpose 1 60 Britt Creek Reach 1 External Utility Gas Line Crossing 2 50 Britt Creek Reach 3 External Maintain Ford Landowner Crossing 3 901 Britt Creek Reach 5 External Maintain Culverts Public RoW & Overhead Utility Easement 1: Final crossing width to be determined based on deed research The easement boundaries around streams proposed for mitigation credit provide the required 50-foot minimum riparian buffer for Piedmont streams. The entire easement area can be accessed for construction, monitoring, and long-term stewardship from Humble Road and Kimesville Road. There are three small airports within five miles of the Site known as Kecks, Causey, and Hinshaw (Green Acres) Airports. Kecks and Hinshaw are both grass strips that appear to be seldom used. Causey is a paved runway with several hangers housing small private aircraft. 4.0 Mitigation Work Plan 4.1 Streams The proposed bank will include 10,789 LF of stream restoration, enhancement level II, and preservation, and 27.406 acres of wetland re-establishment, enhancement, and preservation. These approaches were chosen to provide the highest degree of ecological uplift to the system. Figure 8 provides an overview of the proposed mitigation activities on site. W Wicillands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 11 4.1.1 Restoration Project streams proposed for restoration include Britt Creek Reaches 1, 2, 4 and 6, Jim Branch Reach 2, Alex Branch Reach 2, Ben Branch, Rob Branch Reach 2, and Eric Branch. The restoration reaches are all eroded, and most are incised. 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 wetlands and 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. Outside of a few transition zones at upstream or downstream ends of reaches, all reaches proposed for restoration will be designed with a Priority I approach, raising channel beds to reconnect them with existing floodplains. Implementation of a Priority I approach will result in restoring the natural flooding regime to the floodplain wetlands and decrease the drainage effect on areas that are believed to be drained, historic wetlands. Bank revetments, such as brush toes, will be used to stabilize outer meander bends where necessary. Installation of structures, such as constructed riffles and bed scour inducing structures, within the restored channels will promote water quality, increase bed and bank stabilization, provide bedform diversity, and increase aquatic and terrestrial habitat. Buffers will be planted with native hardwood trees and invasives will be treated within the conservation easement. Wildlands plans to evaluate stream substrate and determine appropriate gradations/bed features for the Site streams. The appropriate substrate will be harvested on -site if possible. 4.1.2 Enhancement II Britt Creek Reach 5 is slated for an Enhancement II mitigation approach. This reach is not incised but does exhibit frequent bank erosion. The primary enhancement activities include streambank stabilization through installation of brush toe and log vanes, replanting as needed, and treating invasive species within the established riparian buffers. 4.1.3 Preservation Britt Creek Reach 3, Rob Branch Reach 1, Jim Branch Reach 1, Alex Branch Reach 1, Gerardo Branch, and Matt Branch are proposed for preservation. These reaches are stable with low bank height ratios, riffle pool sequences, and bedrock outcrops in the channels. The channels will not require any reconstruction or installation of bank or in -stream structures. Supplemental planting will be completed on Gerardo Branch to expand the width of the forested buffer as needed. 4.1.4 Restoration — Not for Credit A portion of Britt Creek Reach 3 is not proposed for credit. This reach flows through the footprint of the old mill pond dam which degrades some stream functions in the immediate vicinity of the dam. 100 LF of this reach is not proposed for credit (50 feet upstream and 50 feet downstream of the dam). W Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 12 4.2 Wetlands Proposed wetland mitigation includes enhancement and preservation of existing wetlands and re- establishment of historic wetlands. Wetland enhancement practices will include hydrologic improvement, invasive species management, and establishment of a native hydrophytic vegetation community. Wetland hydrology will be restored in re-establishment areas through Priority I restoration of project streams and filling existing ditches that accelerate drainage of the floodplain soils. Wetland re- establishment is proposed in areas predominantly containing hydric soils. Some re-establishment is proposed in areas that were slightly short in achieving hydric criteria but contained hydric features between 10 to 20 inches of soil depth. These areas exhibited morphology caused by saturation and infrequent bankfull events, but depletions comprise a slightly lower percentage of the matrix or begin at a slightly greater depth than required to achieve hydric soil criteria (Appendix D). It is highly likely these soils will support wetland hydrology following Priority 1 stream restoration. Wetland credit zones are presented in Figure 8. 4.3 Vegetation Plan Wildlands will work to protect and preserve mature, .; native vegetation where possible. In areas disturbed during construction and in areas lacking native herbaceous and woody vegetation, native riparian buffers will be planted. These areas include along restored and enhanced stream reaches, in all proposed wetland restoration zones, and in all riparian restoration areas. Buffer restoration will involve seeding native herbaceous riparian vegetation and planting appropriate native tree species along the riparian corridor. Herbaceous species in addition to those Planted Rioarian seeded are expected to re-establish naturally throughout the Site due to soil disturbances and deposition on the floodplain. 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. A site -specific planting plan will be presented in the Mitigation Plan and 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 US Army Corps of Engineers (USACE) and IRT guidelines. 5.0 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 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. Performance criteria will be evaluated throughout the seven years of post -construction monitoring. An outline of the performance criteria components follows. �. Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 13 5.1 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. Remedial action would not be taken if channel changes indicate a movement toward stability. In order to assess channel dimension performance, permanent cross sections will be installed on Restoration 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. 5.2 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 an automated pressure transducer. The 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 gauges 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 condition of the created and enhanced 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 areas to adequately �. Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 14 characterize the different soils, vegetation communities, and surface topographic variations that are found across the Site. The LSS reports indicate that hydric soils within the study area are most similar to the Wehadkee series. Performance criteria for the wetland hydrology of the Wehadkee soil series is 12-16%, as provided by the 2016 Wilmington District Mitigation update. An appropriate value within this range will be selected as the wetland hydrologic performance criterion based on further Site investigation. The growing season start date will be based upon soil temperature remaining above 41 degrees Fahrenheit and observation of bud burst, but may not begin prior to March V. The growing season end date will be based on autumn leaf senescence and soil temperature remaining above 41 degrees Fahrenheit. Per USACE guidance, soil temperature probes will be placed at a 12-inch soil depth. 5.3 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 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 native species 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. The extent of invasive species coverage will also be monitored and controlled as necessary throughout the required monitoring period. Vegetation monitoring quadrants will be monitored for seven years and will be installed across the Site to measure the survival of the planted trees. The number of monitoring quadrants required will be based on the October 2016 IRT Mitigation Monitoring Guidance. Vegetation monitoring will occur in monitoring years one, two, three, five, and seven between July 1st and leaf drop and will follow the CVS- EEP Protocol for Recording Vegetation (2008) or another approved protocol. 5.4 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 W Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 15 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. 6.0 Determination of Mitigation Credits The mitigation stream and wetland credit calculations were derived using the USACE 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, enhancement level II activities, and preservation; as well as wetland re-establishment, enhancement, and preservation activities. Stream restoration is proposed at a ratio of 1:1, stream enhancement level II is proposed at 2.5:1, and stream preservation is proposed at 10:1. All areas proposed for wetland re-establishment require hydrologic uplift through stream restoration and filling drainage features. Wetland re-establishment is proposed at a ratio of 1:1. Wetland enhancement is proposed at a ratio of 2:1, 2.5:1, or 3:1 depending on the level of hydrologic uplift needed. Wetland preservation is proposed at a ratio of 10:1. The management objective, the mitigation type, and proposed amount of mitigation is presented in the below Tables 7a and 7b. �.

Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 17 7.0 Credit Release Schedule All credit releases will be based on the total credit generated as reported by the as -built surveys of the Site. 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 be in compliance with the October 24, 2016 Wilmington District Stream and Wetland Compensatory Mitigation Update Guidance Document.

Widllands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 19 7.2 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. 8.0 Maintenance and Long -Term Sustainability 8.1 Maintenance The Site shall be monitored on a regular basis and a physical inspection of the project shall be conducted on average at once per quarter throughout the post -construction monitoring period until performance standards are met. 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 11. Table 11. Maintenance Plan Component/ Maintenance Through Project Close -Out Feature 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 Stream 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 shall be maintained to ensure the health and vigor of the targeted community. Routine vegetation maintenance and repair activities may include supplemental planting, Vegetation 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 boundaries shall be identified in the field to ensure clear distinction between the Site and Site adjacent properties. Boundaries may be identified by fence, marker, bollard, post, tree -blazing, Boundary 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. 8.2 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 �. Wicillands Cape Fear 02 Umbrella Mitigation Bank Underdog Mitigation Site — Draft Prospectus Page 20 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 Site 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. 8.3 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 the performance of the Site. The proposed conservation easement will help to ensure that only USACE and IRT approved activities take place. This easement will be transferred to a USACE and IRT-approved non-profit organization once monitoring success criteria have been achieved. The provider for long-term management of the Site 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 Site will be inspected annually or less frequently as needed to ensure that the Site 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. �.

Most of the study area that was evaluated is wooded but a small area in the eastern most section of the study area is in pasture. METHODOLOGY On February 20`", 2023, Kevin Martin (LSS, PWS) of S&EC, PA performed a preliminary soil evaluation at the site. Hand auger borings were advanced on the property at locations as appropriate to approximately estimate the location and extent of hydric soils within the project area (see attached Figure 1— Hydric Soil Map). Each soil boring was evaluated to assess the presence or absence of hydric soil indicators. Hydric soil indicators were identified utilizing the NRCS Field Indicators of Hydric Soils in the United States - A Guide for Identifying and Delineating Hydric Soils in the United States (Version 8.2, 2018). All areas evaluated are mapped as the Wehadkee (Fine -loamy, mixed, active, nonacid, thermic Fluvaquentic Endoaquepts) by NRCS. Most soils with hydric indicators present between 11" and 20" below land surface were most like the Chewacla soil series (Fine -loamy, mixed, active, thermic Fluvaquentic Dystrudepts). Soils in the non-hydric areas were most like the Congaree soil series. Hydric soils observed onsite are most like the Wehadkee soil series. RESULTS Eighty-five soil borings were performed within the floodplain of Britt Creek. Fifty-nine borings contained hydric (Seventeen of the fifty-nine hydric borings contained only the F19 indicator while forty-two of the hydric soil borings contained the F3b indicator). Sixteen borings contained a hydric soil indicator at 11" to 20" below land surface. Hydric soil indicators were not found within 20" of the soil surface at ten boring locations. See Table 2 — Soil Observations, for the specific findings at each boring location. A circle on the map indicates approximate soil boring locations (see Figure 1— Hydric Soil Map). Green circles are at locations that contained hydric soils while the red circles are at non-hydric soil locations. Yellow circles are at boring locations where the depth to hydric soil indicators was between 11" and 20" below land surface. At all boring locations considered to contain hydric soils, hydric soil indicators were found to begin at less than 10" below land surface. Borings where hydric soils were present contain a depleted matrix and/or the Piedmont Flood Plain Soils indicator. Indicator F3: Depleted Matrix Technical Description: 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) 2 in. (5 cm) if the 2 in. (5 cm) is entirely within the upper 6 in. (15 cm) of the soil, or (b) 6 in. (15 cm) starting within 10 in. (25 cm) of the soil surface. 2 Indicator F19.—Piedmont Flood Plain Soils Technical Description: On flood plains, a mineral layer at least 15 cm (6 inches) thick, starting at a depth <_25 cm (10 inches) from the soil surface, with a matrix (60 percent or more of the volume) chroma of less than 4 and 20 percent or more distinct or prominent redox concentrations occurring as soft masses or pore linings. All borings performed in hydric soil areas contained the F3b and/or F19 indicator within 10" of the land surface. A typical soil profile is attached for borings that were performed at boring locations 25 and 79 and are representative of soil borings that contained only the F3b hydric soil indicator within 10" of the land surface (See Table 1). The profile description performed at boring 18 is representative of locations within the study area containing both the F3b and F19 hydric soil indicators within 10" of the soil surface (See Table 1). 3 oop tram, ~ 82 080 ool 74 In NA 13 1.6 15 ,22 Table 1. — Soil Profile Descriptions Soil Profile #1 Description Soil Profile #1 / Boring Location 18 Hydric Soil Indicator: F19 and F3b Series and Taxonomic Class: Wehadkee (Fine -loamy, mixed, active, nonacid, thermic Fluvaquentic Endoaquepts) Horizon Matrix Redox Features Depth Horizon Color % Texture Notes (inches) (moist) Color (moist) % Type Location 0-2 A 10YR 4/3 100 Sandy Clay Loam 2-8 Bw 2.5Y 5/3 70 7.5YR 4/4 15 C PL Sandy Clay Manganese masses 7.5YR 3/2 15 C M Loam 8-14 Bg 2.5Y 6/2 60 10YR 3/2 25 C M Sandy Clay Manganese and iron masses 5YR 4/6 15 C M Loam Soil Profile #2 Description Soil Profile #2 / Boring Location 25 Hydric Soil Indicator: F3b Series and Taxonomic Class: Wehadkee (Fine -loamy, mixed, active, nonacid, thermic Fluvaquentic Endoaquepts) Horizon Matrix Redox Features Depth (inches) Horizon Color (moist) % Texture Notes Color (moist) % Type Location 0-4 A 2.5Y 5/2 85 5YR 4/6 15 C PL Clay Loam 4-8 Bg 2.5Y 5/1 85 7.5YR 4/6 15 C PL/M Clay Loam 8-12 C 2.5Y 5/1 60 7.5YR 4/4 20 C M Loamy Sand 10YR 5/4 20 C M Soil Profile #3 Description Soil Profile #3 / Boring Location 79 Hydric Soil Indicator: F3b Series and Taxonomic Class: Wehadkee (Fine -loamy, mixed, active, nonacid, thermic Fluvaquentic Endoaquepts) Horizon Matrix Redox Features Depth Horizon Color % Texture Notes (inches) (moist) Color (moist) % Type Location 0-6 A 10YR 4/4 100 Clay Loam 6-12+ Bw 2.5Y 5/2 75 7.5YR 3/3 15 C PL/M Clay Loam 5YR 3/4 10 C PL/M Table 2 - Soil Observations Boring Number Description 1 Depleted Matrix at 12" 2 Chroma <4 with significant concentrations at 14" 3 Depleted Matrix at 19" 4 F3 at 0" 5 Depleted Matrix at 14" 6 F19at10" 7 F19 at 6" 8 Depleted Matrix at 19" 9 Depleted Matrix at 17" 10 F3 at 10" 11 F3 at 2" 12 F3 at 2" 13 F19at10" 14 Upland; Depleted sandy layer at 27" 15 F19 at 6" 16 Upland 17 F3 at 1" 18 F3 at 8" 19 F19 at 8" 20 F19 at 6" 21 F3 at 0" 22 F3 at 6" 23 F3 at 0" 24 F3 at 2" 25 F3 at 0" 26 Depleted Matrix at 16" 27 F3 at 0" 28 F3 at 6" 29 F3 at 6" 30 Chroma <4 with significant concentrations at 14" 31 Chroma <4 with significant concentrations at 18" 32 F19 at 2" 33 Upland 34 Upland 35 Chroma <4 with significant concentrations at 14" 36 Chroma <4 with significant concentrations at 16" 37 F3 at 10" 38 Chroma <4 with significant concentrations at 12" 39 Upland; Chroma <4 with significant concentrations at 24" 40 Depleted Matrix at 16" 41 Depleted Matrix at 14" 42 Depleted Matrix at 16" 43 F3 at 0" 44 F3 at 7" 45 F3 at 0" 46 Depleted Matrix at 19" 47 F19 at 0" 48 F3 at 8" 49 Upland; Depleted Matrix at 24" 50 F3 at 8" 51 Upland; Chroma <4 with significant concentrations at 24" 52 F3 at 8" 53 F3 at 0" 54 F3 at 2" 55 F19 at 0" 56 F3 at 5" 57 F3 at 0" 58 F3 at 0" 59 F3 at 5" 60 F3 at 10" 61 F3 at 8" 62 F19 at 8" 63 F3 at 7" 64 F3 at 0" 65 F3 at 0" 66 F3 at 2" 67 F19 at 8" 68 F19 at 7" 69 F3 at 6" 70 F3 at 0" 71 F3 at 9" 72 F19 at 8" 73 F19 at 6" 74 F3 at 7" 75 Depleted Matrix at 11" 76 F3 at 6" 77 F3 at 7" 78 Depleted Matrix at 11" 79 F3 at 6" 80 F3 at 0" 81 F3 at 6" 82 Upland 83 F19 at 8" 84 F19 at 2" 85 F19 at 6" Appendix E: Effective FEMA FIRM 3710872800L 1820000 FEET 1840000 FEET 800000 FEET 79°36'0"W 79°35'30"W 79°35'0"W 79°34'30"W 79°34'0"W 79°33'30"W 79°33'0"W 79°32'30"W 800000 FEET l:<. tide �' ZONE AE ► r ;ter t� , 1 r AP 792 CL L 1 R A. 35°56'30"N ong Stinking bo r+iK ,� # ,rt , ;� �oYth°Gk Tri'butar7 m q-� a 0,0 35°56'30"N Breen Dr y *f1 I •, 821 a�Y 638.3 $„ YIL SY AI226'8 t s E # co o :w ,; cif > •7 • !yr GrJ r: r ' i P 35°56'0"N 35°56'0"N 833 T 1 r `i '14►. 853 1 031 1 I,.. � � l .f- , r �079 8 � ii 6gs4 ;eP7�1 - L _ asz . ,.-' ' •, � ' `_ E ,00 � oao 583.3 m 00 Q 35°55'30"N r N 1 '.'

An accompanying Flood Insurance Study report, Letter of Map Revision (LOMR) or Letter of Map Amendment (LOMA) revising portions of this panel, and digital versions of this FIRM may be available. Visit the North Carolina Floodplain Mapping Program website at http://www.ncfloodmaps.con or contact the FEMA Map Service Center. Communities annexing land on adjacent FIRM panels must obtain a current copy of the adjacent panel as well as the current FIRM Index. These may be ordered directly from the Map Service Center at the number listed above. For community and countywide map dates refer to the Flood Insurance Study report for this jurisdiction. To determine if flood insurance is available in the community, contact your Insurance agent or call the National Flood Insurance Program at 1-800-638-6620. Flood Insurance Study (FIS) means an examination, evaluation, and determination of flood hazards, corresponding water surface elevations, flood hazard risk zones, and other flood data in a community issued by the North Carolina Floodplain Mapping Program (NCFMP). The Flood Insurance Study (FIS) is comprised of the following products used together: the Digital Flood Hazard Database, the Water Surface Elevation Rasters, the digitally derived, autogenerated Flood Insurance Rate Map and the Flood Insurance Survey Report. A Flood Insurance Survey is a compilation and presentation of flood risk data for specific watercourses, lakes, and coastal flood hazard areas within a community. This report contains detailed flood elevation data, data tables and FIRM indices. When a flood study is completed for the NFIP, the digital information, reports and maps are assembled into an FIS. Information shown on this FIRM is provided in digital format by the NCFMP. Base map information shown on this FIRM was provided in digital format by the NCFMP. The source of this information can be determined from the metadata available in the digital FLOOD database and in the Technical Support Data Notebook (TSDN). ACCREDITED LEVEE NOTES TO USERS: If an accredited levee note appears on this panel check with your local community to obtain more information, such as the estimated level of protection provided (which may exceed the 1-percent-annual-chance level) and Emergency Action Plan, on the levee system(s) shown as providing protection. To mitigate flood risk in residual risk areas, property owners and residents are encouraged to consider flood insurance and floodproofing or other protective measures. For more information on flood insurance, interested parties should visit the FEMA Website at http://www.fema.gov/business/nfip/index.shtm. PROVISIONALLY ACCREDITED LEVEE NOTES TO USERS: If a Provisionally Accredited Levee (PAL) note appears on this panel, check with your local community to obtain more information, such as the estimated level of protection provided (which may exceed the 1-percent-annual-chance level) and Emergency Action Plan, on the levee system(s) shown as providing protection. To maintain accreditation, the levee owner or community is required to submit the data and documentation necessary to comply with Section 65.10 of the NFIP regulations. If the community or owner does not provide the necessary data and documentation or if the data and documentation provided indicates the levee system does not comply with Section 65.10 requirements, FEMA will revise the flood hazard and risk information for this area to reflect de -accreditation of the levee system. To mitigate flood risk in residual risk areas, property owners and residents are encouraged to consider flood insurance and floodproofing or other protective measures. For more information on flood insurance, interested parties should visit the FEMA Website at http://www.fema.gov/business/nfip/index.shtm. LIMIT OF MODERATE WAVE ACTION NOTES TO USERS: For some coastal flooding zones the AE Zone category has been divided by a Limit of Moderate Wave Action (LiMWA). The LiMWA represents the approximate landward limit of the 1.5-foot breaking wave. The effects of wave hazards between the VE Zone and the LiMWA (or between the shoreline and the LiMWA for areas where VE Zones are not identified) will be similar to, but less severe than those in the VE Zone. Limit of Moderate Wave Action (LiMWA) COASTAL BARRIER RESOURCES SYSTEM (CBRS) NOTE This map may include approximate boundaries of the CBRS for informational purposes only. Flood insurance is not available within CBRS areas for structures that are newly built or substantially improved on or after the date(s) indicated on the map. For more information see http://www.fws.gov/cbra, the FIS Report, or call the U.S. Fish and Wildlife Service Customer Service Center at 1-800-344-WILD.
