(LMG) is submitting the following comprehensive mitigation plan to develop the Lower Cape Fear Umbrella Mitigation Bank (LCFUMB). The Bank is designed to provide compensatory mitigation for authorized stream and wetland impacts occurring within the Lower Cape Fear River Basin (USGS 8 -digit hydrologic unit 03030005). The initial phase of the bank will include two tracts located in Brunswick County, North Carolina. Approximately 495 acres of restoration, enhancement, and preservation have been identified within these two non - adjacent parcels. Together the two umbrella bank sites total 513 acres. The White Springs Tract, located near Southport (NC), provides an opportunity to restore the headwaters of a first order stream system impacted by prior ditching and channelization. The existing ditch network has resulted in the removal of characteristic wetland hydrology and provides a direct conduit for contaminant loading to downstream waters. The proposed project will restore approximately 1,334 linear feet of stream habitat and the adjacent wetland communities. Construction at the site will involve the backfilling and /or plugging of the existing drainage network and the re- establishment of natural contours associated with the channelized section of White Springs Branch. The Sneeden Tract, located near Navassa (NC), includes an expansive area of mature, tidal freshwater cypress -gum swamp immediately adjacent to the Cape Fear River and the lower section of Mill Branch. The proposed project will restore the flow regime of Mill Branch via the excavation and removal of an earthen dam. The restoration of characteristic hydrology (i.e. removal of impounded waters and re- establishment of free - flowing conditions) and planting of characteristic small stream swamp vegetation will enhance existing riparian wetlands associated with the run of Mill Branch. In addition, over 400 acres of high quality, mature cypress - gum swamp habitat (i.e. freshwater tidal swamp forest) will be protected in perpetuity. The preservation of such is considered particularly important in light of the current construction of Interstate 140 (i.e. Wilmington Bypass) through the Sneeden Tract, the imminent development of the adjacent lands, and the documented vulnerability of this type of unique, tidal freshwater habitat. The following restoration plan provides specific information regarding the technical approach for the proposed stream and wetland restoration activities. Information regarding the proposed monitoring procedures and long- term stewardship of the project are also provided. Lower Cape Fear Umbrella Mitigation Bank 1 Mitigation Plan — December 2012 SITE IDENTIFICATION AND LOCATION A. Protect Overview On behalf of the Bank Sponsor, Land Management Group, Inc. (LMG) has performed mitigation site evaluations of two tracts of land (White Springs and Sneeden — see Figure 1) located within the Lower Cape Fear River hydrologic unit (USGS 8 -digit hydrologic unit code 03030005). Existing and /or degraded wetland and stream habitat on these properties are to be included within the proposed Lower Cape Fear Umbrella Mitigation Bank ( LCFUMB). The LCFUMB is intended to provide high quality compensatory stream and wetland mitigation to offset authorized impacts occurring within the Lower Cape Fear Basin. The proposed wetland and stream mitigation bank, totaling 513 acres, consists of a variety of wetland habitats that have been previously impacted due to intensive site management practices. The White Springs Tract occupies the headwaters of White Springs Creek, north of Southport (NC), and includes a section of channelized stream and hydrologically altered (i.e. drained) non - riparian wetland habitat. The Sneeden Tract is located immediately adjacent to the Cape Fear River (near Navassa, NC) and includes a large section of existing riverine swamp forest contiguous with tidally - influenced waters of the river and Indian Creek. This tract also includes an impaired section of Mill Branch that is suitable for both stream restoration and wetland enhancement. Based upon site investigations, approximately 88 acres of riparian and non - riparian wetland restoration and enhancement is proposed between the two tracts. The Sneeden Tract will also provide 407 acres of high - quality wetland preservation. Approximately 3,775 linear feet (If) of streams will be restored on the two properties. An additional 1,843 If of first -order stream and 366 If of zero -order headwater valley will be preserved on the Sneeden Tract. The following comprehensive mitigation plan identifies the proposed methods for accomplishing functional uplift of wetlands and streams and provides more specific information related to the implementation and operation of the umbrella bank. B. Site Location The White Springs Tract (totaling approximately 80 acres) is located east of NC Hwy 133 (River Road SE) and immediately north of the Military Ocean Terminal at Sunny Point (MOTSU) Access Road approximately 4 miles north of Southport, NC (Figure 2). The Sneeden Tract is located adjacent to Cedar Hill Road (SR 1430) and approximately two miles north of Navassa, NC (Figure 3). The mitigation bank portion of the property includes 453 acres of riparian habitat situated adjacent to the Cape Fear River. The White Springs Tract contains the Lower Cape Fear Umbrella Mitigation Bank 2 Mitigation Plan — December 2012 headwaters of White Springs Branch, a first -order tributary of Walden Creek which flows east to the Cape Fear River (approximately 3.8 miles from the mitigation site) (Figure 4). The Sneeden Tract is bordered on the north and east by the Cape Fear River and includes the lower section of Mill Branch. The southern portion of the site is bounded by Cartwheel Branch (Figure 5). In addition, Indian Creek (a fourth -order tributary of the Cape Fear River) flows through the swamp forest preservation area of the bank site. Topographic information for each site is depicted via LIDAR data in Figure 6 and Figure 7. The Brunswick County Soil Survey generalized map units for both sites are depicted in Figure 8 and Figure 9. Aerial photography (2004) for both sites are also provided for reference (refer to Figure 10 and Figure 11). II. WATERSHED CHARACTERIZATION A. Watershed Trends Both bank sites are located within the Cape Fear River watershed (DWQ Subbasin 03- 06 -17). The subbasin consists of managed forestry tracts, low- density residential and high density commercial /industrial developments along the HWY 74 and HWY 133 corridors. Population growth within the subbasin is primarily focused in the areas around Wilmington, Leland, and Southport. Streams and waterbodies within the watershed are susceptible to impairment from nutrient loading and low ambient dissolved oxygen (DO) concentrations. According to the Cape Fear River Watershed Restoration Plan (NC DWQ, 2001), a majority of the waterbodies within the subbasin are impaired due to nutrient enrichment and periodic fecal coliform bacteria contamination. The White Springs Tract is also located in an NCDWQ Target Watershed (70010) based on development pressure and declining water quality within the Cape Fear River estuary. Principal stressors to water quality within the subbasin are habitat degradation and low dissolved oxygen. Hydrologic alteration of streams is also recognized as a contributing factor to impairment by facilitating rapid delivery of nutrients, sediments, and other contaminants to downstream waters. B. Surface Water Classifications Surface waters within the project areas drain to tributaries of the Cape Fear River. The NC DWQ surface water body classification for White Spring Branch is SC -HQW and applies to the section directly downstream of the project site (NCDWQ, 2000). "SC" waters are defined as estuarine waters protected for secondary recreation, fishing, wildlife, fish consumption, aquatic life (including propagation), survival and maintenance of biological integrity, and agriculture. Secondary recreation includes wading, boating, and other uses involving human body contact with water where such activities take place in an infrequent, unorganized, or incidental manner. High Quality Waters (HQW) is a supplemental classification intended for waters that demonstrate Lower Cape Fear Umbrella Mitigation Bank 3 Mitigation Plan — December 2012 strong, diverse population of fishes and invertebrates with minimal anthropogenic impacts. Best management practices (BMPs), including riparian buffer setbacks, and other protections are necessary to reduce nutrient and sediment loading in these areas and are essential to help maintaining aquatic health throughout the ecosystem. The waters of Mill Branch are classified as C -Sw, denoting a freshwater swamp (Sw) that is protected for secondary recreation. While the waterfront of the Cape River is heavily industrialized in this area, the headwaters of Mill Branch remain relatively undisturbed. However, it is important to note that Interstate 140 (i.e. Wilmington Bypass) is being constructed through the Sneeden property. As a result, the larger tract of land and adjacent areas are subject to increased development pressure resulting from the access the bypass provides. C. Sub - Watershed Conditions White Springs: The White Springs site formerly consisted of relatively undisturbed non - riparian wetlands situated at the headwaters of a small Coastal Plain stream. Pocosin and pine savanna wetlands, characteristic of the outer Coastal Plain, occurred throughout expansive interstream areas extending west across NC Hwy 133. These type of wetlands support a number of functions /values including, but not limited to the following: groundwater recharge; floodwater storage and attenuation; filtration and storage of nutrients, sediments, and /or toxic substances; and refuge /feeding habitat for resident and migratory fauna. The Pine Savanna community type has been identified as a Significant Natural Heritage Area by the North Carolina Natural Heritage Program (NHP). Pine savannas have among the highest species diversity of any natural community in temperate North America and contain several rare species (NC DWQ 2005). Small, headwater streams work in concert with wetlands to attenuate flood velocities, provide aquatic habitat, and elevate the surrounding water table. At the present time, these functions have been compromised or removed as a result of the existing drainage network and channelization of the White Springs Branch. The Cape Fear River and its tributaries have exhibited significant water quality declines associated with low D0, high total nitrogen, and high total phosphorous. High nutrient concentrations originate from non -point source loading associated with development and silvicultural /agricultural land uses prevalent throughout the upper reaches of the watershed. These impairments tend to be exacerbated by channelization of streams and ditching of adjacent headwater wetlands, resulting in diminished nutrient uptake and rapid delivery of contaminants to down - gradient waters. Sneeden: The large, contiguous cypress -gum swamps of the Sneeden Tract remain largely undisturbed and Lower Cape Fear Umbrella Mitigation Bank 4 Mitigation Plan — December 2012 serve as valuable habitat along the banks of Indian Creek and the Cape Fear River. The tidal freshwater swamp forest habitat of the Cape Fear River is identified as a Significant Natural Heritage Area by the NHP and is classified as vulnerable to extinction (due to its limited range of occurrence and threat to degradation). Along the river, the principal impacts to this habitat type have been from logging and habitat conversion resulting from increased salinities extending further upriver (attributable to sea -level rise and the continued dredging and deepening of the federal navigation channel). Note that ambient water quality stations in proximity to the Sneeden mitigation site have reported persistent low DO and low pH conditions. While this portion of the river may naturally have low DO and pH associated with slow- moving blackwater environments, it is believed that land -use practices in the area exacerbate these impairments. Site - specific impacts to tidal swamp forest habitat type have resulted from prior logging activities and the historic damming of Mill Branch. The presence of the mill dam /causeway has altered natural hydrologic patterns (i.e. conversion to a lentic environment) with resultant impacts to physiochemical and biotic conditions of the stream. The presence of the causeway also restricts tidal exchange between the upper and lower reaches of Mill Branch and likely contributes to decreased dissolved oxygen (DO). More detailed information regarding the functional benefits of removing the causeway is provided in Section III below. III. MITIGATION GOALS A. Protect Purpose The goal of the proposed bank is to provide high - quality compensatory mitigation for permitted impacts within the Cape Fear River Basin via the restoration, enhancement, and preservation of streams and wetlands. The proposed activities will provide functional uplift of various wetland community types including: pocosin, pine savanna, headwater forest, and riverine swamp forest. Based on the sites selected, the following categories of functions will be beneficially affected as a result of the bank restoration work: 1. Biogeochemical Cycling White Springs Tract. The restored stream /headwater wetland system will capture drainage from the surrounding watershed, dissipating energy in the downstream environment. Restoration of groundwater hydrology will promote wetland oxidation /reduction processes that contribute to increased nutrient retention, transformation, and uptake. The removal of ditches and restoration of the low- gradient first -order stream will also reduce sediment loading to downstream waters. Lower Cape Fear Umbrella Mitigation Bank 5 Mitigation Plan — December 2012 Sneeden Tract. Removal of the existing causeway will reestablish characteristic stream flow throughout this affected section of Mill Branch. Free - flowing conditions will allow for normalized sediment transport and will favor for increased dissolved oxygen within surface waters draining into the Cape Fear River. This is particularly beneficial since hypoxia is one of the principal surface water impairments identified within the Lower Cape Fear River. In addition, reduction in the extent of impounded waters will allow for increased primary productivity and resultant effects on nutrient uptake. Restoration of tidal exchange upstream of the causeway will also promote increased export of organic matter for support of downstream food webs. 2. Hydrologic White Springs Tract. Restoration of riparian and non - riparian wetlands will result in increase surface and subsurface water storage. Increases in storage volume will reduce peak flood discharges and will provide valuable baseflow to stream and riparian areas during drier conditions. Re- establishment of characteristic hydroperiods will also promote oxidation /reduction processes necessary for nutrient transformation as identified above. Sneeden Tract. Removal of the causeway of Mill Branch will result in the re- establishment of free - flowing conditions of the stream and its associated physical, chemical, and biologic benefits. The primary hydrologic function will be the re- establishment of tidal exchange upstream of the existing dam /causeway. Hydrologic flux resulting from semi - diurnal tides influence sediment deposition processes and nutrient cycling. Natural small stream conditions (including riffle -pool sequences) will be restored in the upper reaches. Reduction in the area of impounded waters will allow for characteristic tidal freshwater hydroperiods and nutrient exchange. Upstream areas susceptible to flooding will benefit via unimpeded, slow discharge of surface waters through vegetated riparian areas. Typical stream and floodplain processes will be re- established as a result of the removal of the physical impediment to stream flow. Hydrology in other large preservation areas of the tract will remain unaltered, and any future activities potentially adversely affecting wetland /stream hydrology will be prohibited. 3. Biotic White Springs Tract. Re- establishment of characteristic hydrology will promote conditions suitable for plant and animal species that typically inhabit small stream, pocosin, and /or wet pine savanna wetlands. Plantings of characteristic trees and shrubs will also provide for increased foraging, nesting, and refuge habitat. When coupled with the variation in topography, these areas provide valuable heterogeneity which supports a more diverse food web within the Lower Cape Fear Umbrella Mitigation Bank 6 Mitigation Plan — December 2012 ecosystem. This diversity provides a variety of food sources and refuge habitat for local and migratory species. Sneeden Tract. Re- establishment of lotic conditions in Mill Branch will result in functional uplift to biota. Reducing the depth of water within the stream system will increase light attenuation and result in recruitment of characteristic benthic assemblages. In addition, removal of the causeway will allow for unimpeded migration of fish and macroinvertebrates utilizing tidal waters of the Cape Fear River. Restoration of typical riffle -pool sequences will increase habitat heterogeneity within the upper reaches of the stream (particularly in areas situated above the tidal influence of the river). Restoration of natural hydroperiods (including increased tidal amplitude and duration) will promote the recruitment of characteristic tidal freshwater macrophytes. Supplemental planting of characteristic trees and shrubs within the Mill Branch system will also promote increased foraging, refuge, and nesting habitat for resident and migratory fauna utilizing these riparian wetlands. B. Geographic Service Area (GSA) The two tracts are located within the Middle Atlantic Coastal Plain ( Ecoregion 63) as defined by Griffith et al. (2002) "Ecoregions of North Carolina" (refer to Appendix A). This ecoregion encompasses the area defined as the `Carolina Flatwoods' — a subregion occurring along nearly level, poorly drained areas in the outer Coastal Plain including the Lower Cape Fear River Basin. The proposed project will serve as a general use wetland and stream mitigation bank serving the Lower Cape Fear River Basin (USGS 8 -digit hydrologic unit 03030005) as depicted in Figure 12. The purpose of the bank is to compensate for those stream and wetland losses in the basin authorized by applicable federal and state regulatory programs via the restoration, enhancement, and preservation of approximately 495 acres of wetlands and 5,521 If of stream. It should be noted that use of the LCFUMB may be considered acceptable for authorized impacts occurring outside of the identified GSA on a case -by -case basis and upon approval of permitting agencies (i.e. the US Army Crops of Engineers and the NC Division of Water Quality). IV. SITE DESCRIPTION A. Community Types Based on the North Carolina Wetland Assessment Method (NCWAM), the community types occurring on the White Springs Tract are non - riparian pocosin, non - riparian pine savanna, and riparian headwater forest Lower Cape Fear Umbrella Mitigation Bank 7 Mitigation Plan — December 2012 wetlands. The tract has been historically affected by logging and drainage practices resulting in some alteration to vegetation and hydrology. Effects of these activities are more pronounced in proximity to the drainage features. In general, areas further from existing ditches continue to be dominated by characteristic wetland vegetation (see discussion below). Refer to Appendix B for additional information regarding NCWAM field assessments. A majority of the wetlands within the Sneeden Tract would be classified as riverine swamp forest under the NCWAM methodology. These areas include large areas of cypress -gum swamp habitat with isolated sections of small stream swamp vegetation associated with the smaller tributaries. Note that for the purpose of quantifying mitigation credit, the riparian wetlands associated with the cypress -gum swamp of the river are classified as riparian (riverine) wetlands. The small stream swamp wetlands associated with the upper reaches of Mill Creek are classified as riparian (non - riverine) wetlands. More specific information pertaining to existing vegetation, soils, and hydrology is provided in the following sections. Refer to Appendix C for photographs of existing conditions for both the White Springs Tract and the Sneeden Tract. B. Vegetation As indicated above, prior site management practices (including ditching and logging) have influenced the vegetative composition of the White Springs Tract. In general, areas to the north of the main canal tend to consist of Leon soils occurring on slightly higher elevations. The dominant vegetation in these areas is loblolly pine (Pinus taeda) and longleaf pine (Pinus palustris). The shrub layer consists of inkberry (Ilex glabra), blue huckleberry (Gaylussacia frondosa), and highbush blueberry (Vaccinium corymbosum). Common herbs include pineland threeawn (Aristida stricta) and creeping blueberry (Vaccinium crassifolium). Areas closer to ditches have a higher occurrence of species adapted to more well- drained conditions such as horse sugar (Symplocos tinctoria), bracken fern (Pteridium aquilinum), and winged sumac (Rhus copallinum). Characteristic bay shrubs are still prevalent across much of the drained pocosin areas. These include red bay (Persea palustris), loblolly bay (Gordonia lasianthus), fetterbush (Lyonia lucida) and inkberry. Canopy species include loblolly pine and pond pine (Pinus serotina). Species commonly associated with drier conditions are found throughout the previously cleared ditch corridors. These include sassafras (Sassafras albidum), water oak (Quercus nigra), winged sumac, and bracken fern. Much of the previously occurring small stream swamp vegetation associated with the run of the White Springs Branch tributary has been removed as a result of prior site disturbance. The present vegetation along the channel consists of loblolly bay, horse sugar, sweet gum Lower Cape Fear Umbrella Mitigation Bank 8 Mitigation Plan — December 2012 (Liquidambarstyraciflua), loblolly pine, inkberry, and bracken fern. The cypress -gum swamp community within the Sneeden Tract includes a relatively undisturbed canopy of bald cypress (Taxodium distichum) and swamp tupelo (Nyssa aquatica) and tidal freshwater marsh habitat. Additional species such as red bay, American ti -ti (Cyrilla racemiflora), and dwarf palmetto (Sabal minor) are also present. While much of the riverine swamp forest along the river is undisturbed, some areas are subject to impact from logging activities. Prior to the identification of the site for suitable mitigation (approximately 4 to 5 years ago), selective thinning and removal of vines and understory was conducted to enhance the views from the uplands (along an approximate 3,600 If section from west of the natural gas line easement to Mill Creek) in anticipation for residential site development. NCWAM forms were completed as part of the mitigation site evaluation, and the overall wetland rating remained "High ". The selective thinning and removal of dense vines and understory did not have any appreciable effect on the overall functional value of the riverine swamp forest to be preserved. The mature canopy remains intact. The ability to clear -cut the mature cypress -gum swamp and the pending construction of the Interstate 140 bypass is an example of the demonstrable threat to these high - quality wetlands and contextualizes the importance of preservation via a perpetual conservation easement. Remnants of a cypress -gum community were also observed in the lower portions of Mill Branch. Herbaceous species include lizard's tail (Saururus cernuus), pickerel weed (Potenderia cordata), and duck potato (Sagitaria latifolia). This community grades into a small stream swamp community that includes species such as chestnut oak (Quercus michauxii), laurel oak (Quercus laurifolia), water oak (Quercus nigra), green ash (Fraxinus pennsylvanica), and black gum (Nyssa sylvatica). LMG conducted additional site evaluations of Cartwheel Branch and completed NCWAM forms in two locations (one within the main run of Cartwheel Branch and the other within the riparian wetland /tributary on the eastern P /L). Both areas have an overall wetland rating of "High ". These NCWAM forms and the updated NCWAM location map for these assessment areas are included in Appendix B. C. Soil Characteristics The White Springs Tract (located within the headwaters of White Springs Creek) exhibits nearly level to gently sloping topography. The site and surrounding area is primarily comprised of Murville and Leon soil units. These soils are subject to rare to frequent flooding and are considered very poorly drained. Each of these soil units is characterized by low chroma (black or dark gray), often mucky surfaces. The Murville series has a black fine sandy surface layer to approximately 8" and is underlain by dark gray sand typically associated with a spodic Lower Cape Fear Umbrella Mitigation Bank 9 Mitigation Plan — December 2012 horizon (hardpan) which restricts drainage within the profile. The Leon series consists of dark gray to black sand from the surface to approximately 6" and is underlain by a spodic horizon at depths between 14 -18 ". Licensed soil scientists of LMG conducted a detailed soil mapping of the White Springs tract and confirmed the predominance of the Murville and Leon soil series. However, inclusions of other series (typically found in association with Murville and Leon soils) were identified. These series include Mandarin fine sand, Lynn Haven fine sand, and Baymeade fine sand series. The location and extent of the identified soil series is depicted in Figure 13A (overlay on 1998 IR aerial) and Figure 13B (overlay on 1972 black & white aerial). The detailed soil mapping has been used to define the limits of wetland restoration and target wetland community types. The cypress -gum swamp within the Sneeden Tract is mapped as a Chowan silt loam unit. This series is characterized by surficial deposits of silty clay loam that is underlain by several feet decomposed (sapric) organic material. The section of Mill Branch is mapped a Muckalee loam which is common along floodplains in the outer coastal plain of North Carolina. This series is characterized by dark loams within the upper 24" underlain by sandy material to a depth of 48 ". D. Hydrology /Hydraulic Characteristics The White Springs Tract is located within a headwater area that has been historically managed for timber production. An extensive drainage network, comprised of 6,000 linear feet of ditching, effectively drains most of the former riparian and non - riparian wetlands occurring on the property. Installation and maintenance of this network has also impacted the existing stream habitat through the channelization of White Springs Branch. This section was excavated 6- to 7 -ft in depth and channelized from HWY 133 to the southeastern property boundary. These modifications have removed a majority of the in- stream habitat and disconnected the stream from the adjacent floodplain. In an undisturbed system, the small stream swamp areas would be intermittently or seasonally flooded. Relatively undisturbed pocosin and pine savanna wetlands tend to be seasonally saturated with brief periods of inundation. However, the ditch network on the tract has resulted in the drainage of these wetlands by lowering groundwater and intercepting surface water. Drained hydric soils (i.e. low - chroma, friable soils exhibiting a relatively high percentage of uncoated sand grains) are evidenced by oxidation of surficial organic matter along either side of existing ditches on the tract. Given the predominant soil type on the tract and relict hydric soil indicators (e.g. uncoated sand grains), the lateral drainage effect of the ditches is estimated to be approximately 200- to 300 -ft for many of the ditches occurring on the property. Beyond these distances, Lower Cape Fear Umbrella Mitigation Bank 10 Mitigation Plan — December 2012 drainage appears to be somewhat restricted. Estimates of lateral drainage distances are consistent with those values observed in other drained sites with soil groups exhibiting similar hydraulic conductivity and drainable porosity. The lateral extent of drainage was confirmed as part of a jurisdiction determination obtained for the tract (Appendix D). A relatively shallow (i.e. 2- to 3 -ft ditch) exists along an approximate 300 -ft length immediately north of the northern property boundary. This ditch is contiguous with a collector ditch that ultimately ties to the main run of White Springs Branch. The ditch originates in uplands and provides minimal drainage due to its position upslope of the restorable wetlands on the mitigation property. Given its shallow depth and landscape position, it does not appear to have an appreciable effect on the watershed of the receiving stream. Nonetheless, the implications of the presence of this ditch on the wetland restoration effort are discussed in Section V (C) of this plan. Note that moderately well- drained to well- drained nonhydric soils were identified within convex landscape positions near the lower extent of the channelized stream. Under natural conditions, these areas would likely consist of upland long -leaf pine savanna and would not meet the criteria necessary to be considered jurisdictional wetlands. As a result, these areas are outside the proposed limits of wetland restoration. As indicated above, the Sneeden Tract consists of expansive riverine swamp forest associated with the tidally influenced waters of the Cape Fear River as well as a first -order stream (Mill Branch) that has been historically impounded by a mill dam. Stream flow and tidal exchange within the lower portion of Mill Branch has been historically altered via the presence of the dam /causeway. As a result, the natural hydrologic regime within the tributary (including tidal exchange at its lower reach) has been disrupted. Impounded waters create conditions that reduce the delivery of organic material to downstream communities and the tributary's ability to attenuate natural flood events. E. Threatened and Endangered Species A review of the North Carolina Natural Heritage Program database was conducted to determine if there are any known occurrences of rare plant or animal species within or directly adjacent to the White Springs or the Sneeden parcels. A population of Venus flytrap (Dionaea muscipula; FSC; SC) has been observed within the powerline corridor that runs through the White Springs site. No rare species have been observed within the Sneeden site. Lower Cape Fear Umbrella Mitigation Bank 11 Mitigation Plan — December 2012 Several state - listed and federally - listed species have been identified within a one -half mile radius of both sites. Of particular note is the documented presence of red - cockaded woodpecker (RCW) (Picoides borealis) in the vicinity of the White Springs Tract both on the adjacent federal Military Ocean Terminal at Sunny Point and within the nearby community of Boiling Spring Lakes. The eastern portion of the White Springs tract includes longleaf pine savanna habitat suitable for nesting and roosting RCW. Conservation of long -leaf pine habitat is an essential component of the US Fish and Wildlife Service's RCW recovery program. The mitigation bank project will result in the protection of longleaf pine savanna occurring on the property. The Sneeden tract contains unique tidal freshwater swamp forest habitat listed as vulnerable to extinction in North Carolina due to its relatively narrow range of occurrence and threat of disturbance. In particular, tidal freshwater forest of the Cape Fear River downstream of the site has been significantly impacted as a result of saltwater intrusion associated with the continued dredging and deepening of the federal navigation channel. The tidal freshwater community type provides unique refuge, foraging, and nesting habitat to a range of species. In particular, there are documented occurrences of the shortnose sturgeon (Acipenser brevirostrum) (federally - listed as endangered) within this reach of the Cape Fear River. Adults and juveniles of the shortnose sturgeon tend to occur in tidal freshwater areas near the freshwater /saltwater interface and seasonally forage in shallower vegetated areas of the river (NMFS 1998). As a result, protected tidal freshwater wetlands of the Sneeden tract may provide habitat benefits to this endangered species. Refer to Appendix E for a comprehensive list of state and federally listed species and habitats by site. F. Cultural Resources Based upon information provided by the North Carolina Department of Cultural Resources, State Historic Preservation Office (SHPO), there are no known archaeological sites within the proposed mitigation project area. Files do indicate the presence of Reeves African Methodist Episcopal (AME) Zion Church located near the northwest property boundary of the larger "Sneeden" parcel. This church has been considered to be eligible for listing on the National Register of Historic Places. However, it is unlikely that the proposed project will have any effect on resources that may be eligible for inclusion in the National Register of Historic Places. As a result, no archaeological investigations were recommended in connection with the mitigation bank project. Please refer to the correspondence provided by the SHPO (Appendix F). G. Jurisdictional Determinations Ajurisdictional determination (USACE Action ID No. 200401088) previously issued for the White Springs Tract (formerly 114 acres) verified that the 80 -acre mitigation bank site did not contain any jurisdictional wetlands. Lower Cape Fear Umbrella Mitigation Bank 12 Mitigation Plan — December 2012 The ditches (including the channelized tributary of White Springs Branch) have been identified as "Waters of the US. A formal wetland delineation of the entire Sneeden Tract was conducted in January 2010. The delineation was subsequently approved during a site visit with USACE staff on August 17, 2010. Based on the boundaries of the approved delineation, a total 446 acres of jurisdictional wetlands exist within the larger property (note that this includes acreage within deeded easements and right -of- ways). Wetlands associated with Mill Branch and the Cape Fear River that can be preserved via a conservation easement (approximately 453 acres) will be included within the proposed Bank project. The wetland boundary surveys for both tracts are provided in Appendix D. V. RESTORATION PLAN - WHITE SPRINGS TRACT A. First -Order Stream and Riparian Wetland Restoration Like other small, blackwater streams of the Coastal Plain, White Springs Branch is susceptible to water quality impairment resulting from non -point source discharges of contaminants — including nitrogen, phosphorous, and sediment. Ditches, channelized tributaries, and canals drain an approximately one square mile of area within the watershed. These surface waters serve as direct conduits for sediment, nutrients, and other pollutants entering both White Springs Branch and the Cape Fear River estuary. The channelization of streams contributes to channel instability and reduced attenuation on -site. This, in turn, results in increased flooding and bank erosion for down - gradient areas. The natural replenishment of fine sediments and nutrients from floodwaters onto the floodplain wetlands within the site has been virtually eliminated so that sediment accumulation is occurring along the stream bed and nutrients are being shunted downstream. The physical alteration of the stream bed adversely affects biological communities through direct mortality, habitat loss, and shifts in species composition. Prior to the installation of the drainage improvements, the natural watershed of White Springs Branch included a natural pocosin - Carolina bay wetland complex of approximately 150 acres (refer to historic aerials provided in Appendix G). Diffuse flow conditions (with increased retention) likely persisted before collecting into a single thread channel on the lower portion of the site (Figure 4). Surface water is now carried directly into the upper reach of the branch via a reinforced concrete pipe culvert across NC HWY 133. The restoration layout for both the stream and adjacent wetlands is depicted in Figure 14A and Figure 14B. The mitigation work will include Lower Cape Fear Umbrella Mitigation Bank 13 Mitigation Plan — December 2012 Priority II restoration of the single- thread channel beginning approximately 1,250 ft from the culverts at NC HWY 133. Work within the existing channel between NC 133 and the start of the single- thread stream will include the construction of a channel bench and adjustment to the channel bed elevation (refer to the attached Construction Plan Set in Appendix H). While channel hydraulics will be sufficient to support an intermittent stream between Station 10 +00 and Station 22 +50, stream credit is not proposed for the work performed in this segment of channel (since it is unlikely that a stream channel existed historically in this portion of the site). All existing lateral ditches that flow into the channel will be effectively removed via backfilling. Based upon HEC- RAS modeling and research of other small Coastal Plain streams, the contributing watershed will readily support the restoration of an intermittent stream channel below Station 22 +50. Riparian restoration will be limited to the floodplain of the restored stream channel. Hydraulic /Hydrologic Restoration: Removal of the lateral drainage ditches will promote increased residency times within adjacent wetlands and help re- establish characteristic baseflow to the restored channel. The invert of the stream channel will be raised to a depth of 33.00 ft MSL (Bkf = 34.00 ft MSL) at its upstream origin to 27.00 ft (Bkf = 28.00 ft) at its downstream terminus. Note that the existing elevations along the channel profile are 29.5 ft (origin) and 27.0 ft (terminus). The average depth of the channel will be 1.0 ft (riffle section) to 1.33 ft (pool section). The adjacent floodplain will range in elevation from 34 ft (upstream) to 31.5 ft (downstream). The restored channel will be characteristic of low -order streams of the outer Coastal Plain. Restoration will result in the re- coupling of the channel with its adjacent floodplain — thereby reducing episodic discharge to downstream waters. The design slope 0.11 %, and the design bankfull width is 8.00 ft. The design stream type is E5 (Rosgen 1994). The maximum width of the riparian floodplain corridor will be 100 -ft. The total length of the restored channel will be 1,334 If. Additional buffer will be protected on both sides of the stream channel for its entire length. Application of the stream buffer effectiveness correction factor (SBCF), and protection of buffer with a minimum width of 151 If results in a 13% increase in stream credit. Lateral ditches that tie into the main stream channel will be plugged using impervious clay material. Existing spoil piles will be removed and the existing channel will re- graded to form a gently sloping valley. Material generated from the excavation of the floodplain bench and the removal of prior spoil piles will be used to backfill lateral ditches. Ditches north of the existing channel will be backfilled first. As construction continues downstream, the balance of the earthwork will be used to fill in the lateral ditches on the south side of the channel to the maximum extent practicable. The removal of the incised, straightened channel and shaping of the natural valley will result in the reconnection of a diffuse flowing stream with adjacent riparian wetlands. More detailed information is provided as part of the design plan set included in Appendix H. Lower Cape Fear Umbrella Mitigation Bank 14 Mitigation Plan — December 2012 Hydrologic restoration of the riparian corridor will be achieved via the removal of the incised channel and plugging of lateral ditches that drain to the channel. Valley contours will be re- established within the identified riparian corridor. This corridor has remnant spoil piles on both sides of the channel. Deepening and channelization of the valley has resulted in the functional disconnection of stream flow and adjacent flood - prone areas. Upon completion of final grades, the restored valley will mimic the gentle sloping gradient that existed prior to site drainage impacts. Restored riparian wetland areas will be subject to periodic inundation resulting from diffuse surface flow within the valley. Hydrologic restoration will also be achieved via removal of lateral ditches and raising the bed elevation of the valley floor (resulting in elevated groundwater elevations within the riparian areas). Vegetative Restoration: Vegetation of the stream banks and riparian wetlands will be restored to more closely resemble characteristic small stream swamp communities of the Coastal Plain. Specifically, the restored valley corridor will be replanted with bald cypress (Taxodium distichum), swamp tupelo ( Nyssa biflora), American titi (Cyrilla racemiflora), loblolly bay (Gordonia lasianthus), and American holly (Ilex opaca). Seedlings will be planted on 9 -ft spacings, corresponding to 538 trees per acre. It is expected that other characteristic species will recruit naturally into these restored areas upon successful hydrologic restoration. Live - stakes of coastal species will also be installed to promote bank stabilization and provide for more rapid cover and shade for the restored channel. See Table 1 for specific planting information. Table 1.

Non - Riparian Wetland Restoration Project activities will result in the restoration of 66.1 acres of non - riparian pocosin and pine savanna wetlands. These areas form the headwaters of White Springs Branch. Re- establishment of characteristic hydroperiods will be achieved via the removal of the ditch network draining the property. Given that the entire extent of the Lower Cape Fear Umbrella Mitigation Bank 15 Mitigation Plan — December 2012 proposed restoration area is vegetated, work will focus on restoration of characteristic hydrology. No plantings will be necessary since the predominant shrub and tree species are typical of the target wetland communities. The following is a description of the proposed hydrologic restoration. Hydrologic Restoration. Precipitation serves as the primary hydrologic input for wetlands in this landscape position. By removing the groundwater outflows (via ditches) and increasing surface water retention, natural hydroperiods of pocosin and wet pine savanna will be achieved. Impervious clay plugs will be installed at prescribed locations within the existing ditch network (refer to Appendix H). Plug material will be obtained from an off -site source and transported to the site for installation. Plugs will range in length from 50 ft to 100 ft and will be constructed in a manner to reduce the risk of down - cutting or by- passing. Specifically, the material will be compacted utilizing excavator equipment and will extend beyond the widths of the ditches. In addition, areas up- gradient from the plugs will be backfilled utilizing material resulting from the construction of the first - order stream channel. In order to ensure that the proposed work will result in the re- establishment of characteristic wetland hydrology, LMG performed detailed soil mapping of the site and performed hydrologic modeling utilizing specific design inputs. DrainMod utilizes Reference Wetland Simulation and is an approved hydrologic modeling application. It is particularly useful for performing water budget modeling for wetland flats or interstream depressions (including pocosins and Carolina bays) in which the principal hydrologic input is precipitation. The model has been further calibrated using site - specific data (including hydraulic conductivity and hydrologic data). Note that non- hydric areas have been identified on the tract and will be excluded for consideration of wetland restoration. DrainMod incorporates long -term climatological data in concert with site - specific model inputs. The White Springs project was modeled using climate data over a 30 -year period between 1965 and 1995. Final design dimensions of the main channel (non- stream portion) and the down - gradient first -order stream were utilized to perform the model runs. Since channel depths varied between stations, several runs were performed. Modeling indicated that wetland hydrology would not be achieved within an approximate 390 -ft to 454 -ft corridor of the upper channel (non- stream portion). This is equivalent to an effective lateral drainage distance of 195 ft to 227 ft for each side of the channel. Based upon these findings, the Sponsor will be installing a clay liner along both sides of this section of channel to prevent lateral drainage effects — thus promoting groundwater retention in the adjacent pocosin wetland areas. Note that an existing, relatively shallow (approximately 3 -ft deep) ditch originates in uplands north of the northern property boundary and eventually ties into a collector ditch within the mitigation site. The ditch is Lower Cape Fear Umbrella Mitigation Bank 16 Mitigation Plan — December 2012 situated on a slightly higher elevation from the wetlands of the restoration site and appears to have minimal effect on the adjacent hydrology. DrainMod simulations using existing ditch geometry and mapped soils suggest a lateral drainage influence of 150 ft. Even though this ditch appears to have negligible effect on adjacent groundwater, the Sponsor will install a plug near the property boundary such that any outflow will be restricted. VI. RESTORATION PLAN - SNEEDEN TRACT The mitigation bank area on the Sneeden Tract consists of a total of 441 acres of riparian wetland and stream mitigation (Figure 15). Note that the total acreage also includes an additional 25 -ft upland boundary around all riparian wetlands. The additional buffer is viewed as particularly beneficial in light of the approved planned unit development (PUD) of the larger parcel. Note that a future 60 -ft right -of -way has been excluded from the conservation easement along the upper segment of Mill Creek to reserve access to the northwestern portion of the site. The crossing within this excluded right -of -way will consist of a future bridge (span). Approximately 407 acres of high - quality tidal freshwater swamp forest (classified as vulnerable to extinction by the NC Natural Heritage Program) will also be preserved as part of the mitigation bank. The following is more specific information related to stream restoration and riparian wetland restoration and enhancement on the property. A. Stream Mitigation A majority of the stream channel within the lower reach of Mill Branch has been converted to open water via the presence of a mill dam that has historically impounded water and removed any tidal influence at this location. Impounded waters have been documented by hydrologic data demonstrating nearly static water levels ranging from 18- to 24- inches above the soil surface (Appendix J). As stated earlier, the impediment to flow results in adverse impacts to sediment transport, nutrient exchange, and dissolved oxygen concentrations. Impounded waters also submerge in- stream structures, reducing habitat heterogeneity necessary for invertebrate and fish communities. The limits of stream restoration have been defined based upon the extent of long -term ponded conditions. Physical indicators of inundation (including water marks on trees, changes in vegetation, and the presence of adventitious roots) in conjunction with stream profile and LIDAR data were used to assist in this determination. Natural hydroperiods and flow regimes will be achieved via the removal of the entire causeway and grading of a natural channel connection. The work will result in the reconnection of the lower reach to the upstream watershed. As a result, in- stream fauna will benefit from an increase in pH, oxygen, and habitat diversity as Lower Cape Fear Umbrella Mitigation Bank 17 Mitigation Plan — December 2012 the system readjusts to the natural flooding regime of a tidally - influenced, first -order Coastal Plain stream. Grading work will require the construction of a temporary diversion ditch that will allow for removal of the road to be conducted under drier conditions. A temporary rock check dam will be installed at the down - stream side of the existing causeway. The road bed will be removed and the channel will be graded to 3:1 side slopes to tie to existing grades both on the upstream and down - stream limits of disturbance. The existing corrugated metal pipe will be removed. Refer to design plan set provided in Appendix H for more detailed information regarding grading and erosion control measures. The proposed work will result in the restoration of approximately 2,441 If of stream restoration. In addition to the stream restoration, approximately 1,843 If of first -order stream and 366 If of high - quality, undisturbed zero - order stream valley will be preserved. Refer to Figure 15A for the extent of proposed stream restoration and preservation. B. Riparian Wetland Mitiaation Removal of the causeway will result in the direct restoration of riparian wetlands within its former footprint and the enhancement of wetlands up- gradient from the structure. The grading work will allow for re- establishment of characteristic riparian wetland hydroperiods and tidal exchange via the re- connection of the stream to tidally - influenced waters of the Cape Fear River. Areas within the restored and enhanced riparian wetland areas will be planted with characteristic cypress -gum swamp species. Target species will include swamp tupelo, green ash, and bald cypress. Sub - canopy species will consist of ironwood and American holly. Revegetation within the floodplain will provide additional shading for the stream channel and refuge habitat for fauna. Refer to Table 2 for specific planting information. i apse z. sneeaen i race rlaniing clan Cypress-Gum Swamp 5 acres +/- (includes supplemental planting in enhancement areas) Riparian Wetland Restoration /Enhancement Rio Common Name Scientific Name Composition # Planted Bald Cypress Taxodium distichum 30 807 Swamp Tupelo Nyssa biflora 20 538 Green Ash Fraxinus pennsylvanica 20 538 American Holly Ilex opaca 10 269 River Birch Betula nigra 10 269 Ironwood Carpinus caroliniana 10 269 TOTAL 2,690 Lower Cape Fear Umbrella Mitigation Bank 18 Mitigation Plan — December 2012 The extent of the riparian wetland restoration will be confined to the footprint of the causeway to be removed (approximately 0.5 acres). Based upon the upstream influence of the causeway (documented through observations of physical indicators of ponding), approximately 20 acres of riparian (riverine) wetlands will be enahanced. An additional 403 acres of riparian (riverine) and 4 acres of riparian (non - riverine) wetlands will be preserved via the conservation easement deed. VII. BANK IMPLEMENTATION Use of credits from the Bank to offset wetland and stream impacts authorized by federal permits or state water quality certifications must be in compliance with the Clean Water Act, Section 404 (b)(1) guidelines and other applicable federal and state legislation, regulations, and policies. Prior to release of bank credits, the following requirements will be met: (1) approval of the final mitigation plan and execution of the instrument; (2) recordation of the conservation easement; and (3) establishment of appropriate financial assurances. Mitigation bank credits will be calculated using the following standard: Mitigation Type Ratio (1) Stream Restoration 1:1 (2) Stream Enhancement 1.5:1 (3) Stream Preservation 2.5:1 (4) Wetland Restoration 1:1 (5) Wetland Enhancement 2:1 (6) Wetland Preservation 5:1 Given the identified ratios for wetland restoration, enhancement, and preservation, it is estimated that 159.8 wetland credits will be derived from the establishment of the Lower Cape Fear Umbrella Mitigation Bank. An additional 4,681 stream credits will result from the mitigation effort. Credit types and amounts are specified within Table 2 and Table 3. Debiting and accounting procedures for the bank credits will be specified within the banking instrument to be executed by the Sponsor and IRT representatives.

The instrument provides detailed information regarding bank operation. Prior to execution of the banking instrument, the Sponsor will secure insurance policies in amounts sufficient to assure completion of all mitigation work, required monitoring and reporting, and any remedial actions necessary for site success. Once the final mitigation plan is approved and the accompanying instrument executed by members of the IRT, the Sponsor will record a conservation easement for the bank site. Implementation of earthwork will be initiated upon receipt of applicable state and federal authorizations. The tentative start date for construction is June 2013. Construction at both sites will occur in one phase and is anticipated to be completed during the winter of 2013. Site planting will be initiated in January 2014. Upon completion of construction, a survey of the project site will be conducted and an "as- built" report will be submitted (anticipated Spring 2014). Based upon this schedule of events, the first year of annual monitoring will be conducted in September 2014 and continue until 2021 (Table 4). Table 4.

MONITORING PLAN - WHITE SPRINGS TRACT A. Overview Upon agency concurrence of the final wetland mitigation plan, mitigation site activities will be initiated. Staff environmental scientists will be present during project construction to ensure that the work is consistent with the proposed design. An `as- built' survey will be prepared to document site conditions immediately post - construction. Each phase of the site will be monitored annually for a period of 7 years (or until such time deemed successful) whichever is longer, to document site development over time. Each annual monitoring report will contain monitoring information which documents the progress of each site to date. Based upon the current timetable, it is anticipated that construction will be completed in September 2013 and planting completed in February 2014. Thus, the corresponding as -built report is anticipated to be submitted in May 2014. Monitoring reports (submitted annually to reviewing agencies) will include results of hydrologic and vegetative monitoring in addition to photographic documentation of site conditions. All monitoring reports will be submitted to the IRT by February 1 of each year. As part of an adaptive management approach, monitoring reports will identify any contingency measures that may need to be employed to remedy any site deficiencies. Prior to any site modifications, the specific contingency measure will be identified and submitted to the USACE for their review and concurrence. Reports will be in compliance with RGL 06 -03 and RGL 08 -03. More specific information related to adaptive management and long -term site management is provided in Section X. B. First -Order Stream Success Criteria The primary success criteria for the First Order Stream will be: Documentation of 2 bankfull events using techniques discussed below within a normal rainfall year in 3 of the 5 years of monitoring. Additional monitoring may be necessary in the event of abnormal climatic conditions. Level 1 Monitoring will be employed as detailed in the Stream Mitigation Guidelines, April 2003. Monitoring will occur every year for the five year monitoring period. Monitoring reports will be prepared each monitoring year and will include completed Channel Mitigation Monitoring Sheets with current data, a discussion of any deviations, and whether they are indicative of a stabilizing or destabilizing situation. Lower Cape Fear Umbrella Mitigation Bank 22 Mitigation Plan — December 2012 Level 1 Monitoring includes the following: (1) Photo - Documentation Extensive photo documentation is proposed for the stream monitoring phase of this project. Photos will be taken at all permanent cross - sections on a bi- annual basis (winter and summer) in addition to any problem areas that may develop after construction is completed. Photos will be georeferenced to the corresponding cross - section and /or problem area as part of the submitted report. Photo documentation will also be used to document the health of the riparian area plantings and the effectiveness of any erosion control measures. (2) Ecological Function The health of the riparian vegetation will be documented as part of the wetland restoration monitoring efforts. Three 0.05 -acre permanent monitoring plots will be established throughout the riparian wetland restoration including areas directly adjacent to the restored channel. The success criteria for wetland restoration are provided in Section VIII. (C) below. (3) Channel Stability /Survey Procedures a. Cross - Sections (First Order Channel) The White Springs tract includes the restoration of 1,334 If of first order Coastal Plain stream. The restoration will mimic low gradient, low velocity stream reaches characteristic of the outer Coastal Plain. No hardened materials (i.e. rock structures) will be used. Rather, natural materials (such as root wads and log vanes) will assist with channel stabilization and grade control. Given the size, uniform design, and gentle slope (0.11 %) of the proposed project, four permanent cross - sections will be established on approximate 330 -ft intervals of stream length. Placement of these stations will be designed to assess the performance of potential problem areas (e.g. severe erosion, structural failure, etc.). These stations will also be distributed between riffles and pools (two in riffles and two in pools) throughout the project. Refer to Figure 16 depicting the approximate location of the proposed cross - sections. b. Longitudinal Profiles (First Order Channel) Given the length of the restored channel (1,334 If), a longitudinal profile of the entire restored reach will be performed. Data presented in the annual monitoring reports will be shown in comparison to as -built conditions. c. Stream Flow Monitoring (First Order Channel) Documentation of stream flow within the project will also be conducted. Following stream construction activities, two (2) stream gauges will be installed (Figure 16). These gauges will measure the elevation of Lower Cape Fear Umbrella Mitigation Bank 23 Mitigation Plan — December 2012 water in the channel on an hourly basis and will be used to determine the cross - sectional area of the channel under a variety of flow conditions. In addition to these data, velocity measurements will be collected after varying rain events at each gauge location during Year 1 monitoring. Measurements will be collected at 1 -foot intervals across the restored channel at depths of 0.5 ft. above the bottom. This information will be used to compute a total discharge measured in cubic feet per second for each reach for the duration of the monitoring activities. All data will then be used to develop a regression analysis which will define the relationship between rainfall events and total stream discharge. These data will be presented in graphical format with individual bankfull and high flow events highlighted. C. Wetland Success Criteria The wetland restoration effort will be evaluated based upon performance criteria related to vegetative density and wetland hydrology. Vegetative data will include information on specific species and height within individuals monitoring plots located throughout the project area. Wetland hydrology data will be collected using automated groundwater monitoring wells which will be installed in each of the three restored habitats. Each of these habitats will have a separate target for duration of water table depths within 12" of the soil surface during the growing season. The primary success criteria for the White Springs Tract will be: (1) Demonstrated density of planted species to meet or exceed 210 trees per acres at the end of 7 years (post planting). (2) No single volunteer species (most notably, red maple, loblolly pine, and sweet gum) will comprise more than 50% of the total composition at year 2 or 3. If this occurs, remedial procedures will be implemented. During years 4 &5, no single volunteer species, comprising over 50% of the total composition, may be more than half the height of the planted trees. If this occurs, remedial procedures will be implemented. (3) The hydrologic criterion is premised on the specific community type to be restored. (a) For the riparian small stream swamp community, the hydrologic criterion will be the establishment of a static water table at, or within, 12" of the soil surface for 12% of the Lower Cape Fear Umbrella Mitigation Bank 24 Mitigation Plan — December 2012 growing season (equivalent to 36 days based upon a growing season between February 1st and November 3011)' during periods of normal precipitation conditions. (b) For the non - riparian pocosin community, the hydrologic criterion will be the establishment of a static water table at, or within, 12" of the soil surface for 10% of the growing season (equivalent to 30 days based upon a growing season between February 1st and November 301h) 1 during periods of normal precipitation conditions. (c) For the non - riparian pine savanna community, the hydrologic criterion will be the establishment of a static water table at, or within, 12" of the soil surface for 7% of the growing season (equivalent to 21 days based upon a growing season between February 1st and November 301h)' during periods of normal precipitation conditions. Vegetation Monitorinq: Planted wetland areas of the riparian headwater forest (1.8 acres) will be monitored via the establishment of permanent 0.05 -acre plots (20 meter x 10 meter). Two (2) permanent plots will be established in this restored community type (equivalent to 6% of the planted area). GPS coordinates for the corners of each sampling plot will be recorded and included with the `as- built' survey and subsequent annual monitoring reports. During monitoring, surviving planted individuals and volunteer individuals will be enumerated within each plot. Since the pocosin and wet pine savanna portions of the restoration project are vegetated with target species and since there will be a limited area of disturbance associated with the hydrologic restoration, no additional site planting is proposed outside of the riparian wetland corridor. It is anticipated that natural recruitment of bay shrubs will readily occur and contribute to the overall target species composition. Qualitative information related to vegetation (e.g. species type and relative abundance) for each community type will be provided within the annual monitoring reports. Hydrologic Monitoring: Shallow groundwater hydrology in the restored wetlands will be monitored via eleven (11) automated wells (RDS, Inc. WM -20s) located within riparian and non - riparian wetlands. Two (2) wells will be sited within the riparian wetland corridor. Of the remaining nine (9) wells, seven (7) will be installed in representative locations within the restored pocosin and two (2) will be installed within the restored pine savanna. Refer to Figure 16 depicting the approximate locations of the groundwater level monitoring wells. ' Growing season based upon direction of IRT. Lower Cape Fear Umbrella Mitigation Bank 25 Mitigation Plan — December 2012 Wells will be installed in accordance with installation methods outlined in the Wetlands Regulatory Assistance Program (WRAP) Technical Note 00 -02 (Sprecher, 2000). Water levels will be recorded once daily. Data will be downloaded from the wells every three months (i.e. once quarterly). Data from well downloads will be compiled and graphically displayed to demonstrate hydroperiods of monitored areas. Reference Sites: A total of three (3) wells have been installed within reference wetland areas on the adjacent 442 -acre Brunswick County site located to the east and northeast of the Bank site The location of these reference wells are depicted on Figure 16. Water table data downloaded from these wells will be used to establish baseline conditions in the event of abnormal precipitation conditions within the monitoring period. Data will also be included in the AMR to allow for additional comparative analysis. IX. MONITORING PLAN - SNEEDEN TRACT A. Riparian Wetland Restoration Given the size of the causeway to be removed and the relatively small area of planting, no permanent vegetation plots will be established. Rather than employing typical performance criteria, the area will be monitored for the presence of invasive species. Percent coverage of any invasive species will be reported relative to the relative abundance of other species (either planted or volunteers) within the area of the former causeway. Note that invasive species include, but are not limited to: (1) Chinese privet (Ligustrum sinense); (2) mimosa tree (Albizia julibrissin); (3) tallowtree (Triadica sebifera); (4) kudzu (Pueraria montana); and (5) morning glory (Ipomoea spp.). Hydrology will be monitored via the installation and operation of two (2) shallow - groundwater monitoring wells. The location of the proposed monitoring wells are depicted in Figure 17. An as -built topographic survey will confirm removal of the road and suitable elevations. The success criteria of the restored riparian wetland will be: (1) Invasive species not to exceed 20% relative abundance compared to other planted or volunteer noninvasive shrubs/trees. Note that red maple (Acer rubrum) and sweet gum (Liquidambar styraciflua) are not to be considered invasive for the purpose and intent of this success criterion. If invasive species exceed 20% relative abundance, then adaptive management measures (through coordination with the IR7) will be implemented. Lower Cape Fear Umbrella Mitigation Bank 26 Mitigation Plan — December 2012 (2) For the riparian (riverine) swamp community, the hydrologic criterion will be the establishment of a static water table at, or within, 12" of the soil surface for 25% of the growing season (equivalent to 76 days based upon a growing season between February 1st and November 301h)2 during periods of normal precipitation conditions". B. Stream Restoration and Wetland Enhancement Success Criteria Monitoring of the restoration and enhancement areas will focus on documentation of free - flowing conditions within the system. Hydrology data has been collected in the stream channel and adjacent riparian wetlands targeted for enhancement. This information will provide the baseline data from which to evaluate post - construction results. The primary success criteria for the Stream Restoration are: (1) Demonstration of tidal signature (increased amplitude with semi - diurnal frequency) upstream of causeway to be removed (anticipated signature up to 1000 ft beyond causeway); (2) Documentation of free - flowing conditions (relative to pre- construction data and reference stream data) and documentation of removal of impounded waters; (3) Demonstration of stable channel geometry; and (4) Establishment of characteristic geomorphologic heterogeneity (riffle, pool, and run) beyond the limits of the restored tidal influence as identified via physical monitoring. Criteria #1 will be evaluated through the use of automated gauges configured to read surface water levels on an interval of at least once hourly. An existing gauge located immediately downstream of the causeway will be left in place to document the tidal signature at the point immediately below the stream restoration reach. Three (3) additional gauges will be installed upstream to document the extent of tidal influence post- construction. These gauges (in conjunction with riparian wetland wells) will document the reduction of impounded waters and restoration of characteristic hydroperiods. A fourth gauge will be installed near the upstream extent of the proposed restoration to document free - flowing conditions and periodic overbank flooding. Refer to Figure 17 for a depiction of the proposed monitoring of the Mill Creek restoration. 2 Growing season based upon direction of IRT. Lower Cape Fear Umbrella Mitigation Bank 27 Mitigation Plan — December 2012 Criteria #2 will be evaluated through a combination of stream gauges (as described above), stream flow meters, and video documentation. Free - flowing conditions and reduction of impounded waters will be documented throughout the reach. In addition, channel velocity measurements (collected beyond the limits of the restored tidal signature) will be collected within 24 hours of varying rain events. Data will be used to calculate total discharge measured in cubic feet per second near the upstream limit of the restored reach. A regression analysis will be performed to determine the relationship between rainfall events and total stream discharge. As indicated above, physical monitoring (cross- sections and longitudinal profile) will be used to determine if Criteria #3 and #4 are met. Three (3) permanent cross - sections will be installed (alternating riffle /pool sections) to document channel stability. A longitudinal survey of the entire restoration reach will be performed on an annual basis to document riffle -pool sequences and to document any bed aggradation or erosion. The primary success criterion for the Riparian Wetland Enhancement will be: (1) The hydrologic criterion will be the establishment of a static water table at, or within, 12" of the soil surface for 25% of the growing season (equivalent to 76 days based upon a growing season between February Is' and November 301")3 during periods of normal precipitation conditions and the duration of surface ponding (in excess of 2 inches above soil surface) not to exceed 10% of the growing season (equivalent to 30 days based upon a growing season between February Is' and November 301h) during periods of normal precipitation. Shallow groundwater hydrology will be monitored via six (6) automated wells (RDS, Inc. WM -40s) located within the enhancement areas (refer to Figure 17). Wells will be installed in accordance with installation methods outlined in the Wetlands Regulatory Assistance Program (WRAP) Technical Note 00 -02 (Sprecher, 2000). Water levels will be recorded once daily. Data will be downloaded from the wells every three months (i.e. once quarterly). Data from well downloads will be compiled and graphically displayed to demonstrate hydroperiods of monitored areas. A reference riparian wetland area will also be monitored to provide comparative data on the performance of the wetland enhancement. s Growing season based upon direction of IRT. Lower Cape Fear Umbrella Mitigation Bank 28 Mitigation Plan — December 2012 X. SITE MANAGEMENT A. Adaptive Management The Lower Cape Fear Umbrella Mitigation Bank is planned and designed to be self- sustaining over time, but some active management or maintenance may be necessary to ensure the long term sustainability of the mitigation efforts. The adaptive management approach involves analysis of monitoring results to identify potential problems occurring on the site and the identification and implementation of measures to rectify those problems. Remedial actions may include, but are not limited to, mechanized earth work (e.g. adjustment to the invert elevations of earthen plugs) or supplemental planting in the event areas do not meet vegetative success criteria. Prior to initiating any remedial actions the proposed measures will be submitted to the USACE for review and approval. Performance and functioning of the mitigation site may be affected by various causative factors, both natural and anthropogenic. Natural hazards may include invasive species and /or excessive herbivory. Human errors may include design flaws, construction deviation, and /or inadequate planting coverage. To minimize these potential problems, the following strategies may be employed: 1. If herbivory appears to be jeopardizing the survivorship of planted species, discussions with appropriate agencies will be initiated to determine an appropriate course of action. 2. Beavers will be trapped from the tract if significant damage appears to be caused by beaver activity. 3. Construction errors will be identified as early as possible via the as -built report. If it appears as those potential errors jeopardize the integrity of the project, appropriate remedial action will be identified and submitted to the USACE for concurrence prior to implementation. 4. Planting errors in spacing density or coverage will be minimized by careful coordination with planting crews. An account of planted stems will be provided with the as -built report. 5. If monitoring indicated a potential design flaw, remediation options will be reviewed. 6. In the event groundwater monitoring wells are damaged by bears, barb -wire fencing and /or other acceptable deterrents may be used to protect wells from further damage. 7. If invasive species exceed the identified percent coverage, then the Sponsor or its agent will coordinate with the IRT for appropriate invasive species control (including physical removal and /or application of herbicide approved for use in wetlands or aquatic sites). Lower Cape Fear Umbrella Mitigation Bank 29 Mitigation Plan — December 2012 B. Long -Term Management Land use and property boundaries along with the proposed mitigation plan were designed to minimize long term management conflicts. As a result, the potential for hydrologic and boundary conflicts have been minimized. The Sponsor has identified the Land Trust for America (formerly known as Audubon Environmental Land Trust) as the grantee of the conservation easement deed. The recorded conservation easement deed will ensure the protection of the project in perpetuity. XI. CONCLUSION Detailed site assessments of the two tracts have confirmed the presence of conditions suitable for wetland and stream mitigation. Based on these investigations and subsequent mitigation design, a total of 495 acres of riparian and non - riparian wetlands will be restored, enhanced, and preserved as part of the mitigation bank project. Re- establishment of characteristic hydroperiods will result in water quality benefits (e.g. increased sediment retention, enhanced nutrient transformation and uptake, increased dissolved oxygen) within a rapidly urbanizing watershed. Additional benefits will also be realized through increases in flood water retention and groundwater recharge rates. Preservation of the expansive area of tidal riverine swamp forest within the Sneeden Tract will also provide for the long -term protection and management of a Significant Natural Heritage Area classified as "Vulnerable to Extinction ". This is particularly beneficial in light of its proximity to the Interstate 140 corridor and the resultant secondary effects of such (i.e. increased industrial and residential development). By providing wetland and stream restoration credits prior to authorized impacts, overall disturbance and loss of function within the watershed are minimized. Furthermore, the Bank will provide for the restoration and preservation of a variety of stream and wetland habitats unique to the outer Coastal Plain and within a watershed particularly susceptible to impairments from increased development pressure.

Ground Surface Condition/Vegetation Condition — assessment area condition metric Check a box in each column. Consider alteration to the ground surface (GS) in the assessment area and vegetation structure (VS) in the assessment area. Compare to reference wetland if applicable (see User Manual). If a reference is not applicable, then rate the assessment area based on evidence an effect. GS VS ®A ®A Not severely altered ❑B ❑B Severely altered over a majority of the assessment area (ground surface alteration examples: vehicle tracks, excessive sedimentation, fire -plow lanes, skidder tracks, bedding, fill, soil compaction, obvious pollutants) (vegetation structure alteration examples: mechanical disturbance, herbicides, salt intrusion [where appropriate], exotic species, grazing, less diversity [if appropriate], artificial hydrologic alteration) Surface and Sub - Surface Storage Capacity and Duration — assessment area condition metric Check a box in each column. Consider surface storage capacity and duration (Surf) and sub - surface storage capacity and duration (Sub). Consider both increase and decrease in hydrology. Refer to the current NRCS lateral effect of ditching guidance for North Carolina hydric soils (see USACE Wilmington District website) for the zone of influence of ditches in hydric soils. A ditch <_ 1 foot deep is considered to affect surface water only, while a ditch > 1 foot deep is expected to affect both surface and sub - surface water. Consider tidal flooding regime, if applicable. Surf Sub ®A ®A Water storage capacity and duration are not altered. ❑B ❑B Water storage capacity or duration are altered, but not substantially (typically, not sufficient to change vegetation). ❑C ❑C Water storage capacity or duration are substantially altered (typically, alteration sufficient to result in vegetation change) (examples: draining, flooding, soil compaction, filling, excessive sedimentation, underground utility lines). Water Storage /Surface Relief — assessment area/wetland type condition metric Check a box in each column. Select the appropriate storage for the assessment area (AA) and the wetland type (WT). AA WT ®A ®A Majority of wetland with depressions able to pond water > 1 deep ❑B ❑B Majority of wetland with depressions able to pond water 6 inches to 1 foot deep ❑C ❑C Majority of wetland with depressions able to pond water 3 to 6 inches deep ❑D ❑D Depressions able to pond water < 3 inches deep ®A Evidence that maximum depth of inundation is greater than 2 feet ❑B Evidence that maximum depth of inundation is between 1 and 2 feet ❑C Evidence that maximum depth of inundation is less than 1 foot 4. Soil Texture /Structure — assessment area condition metric Check a box from each of the three soil property groups below. Dig soil profile in the dominant assessment area landscape feature. Make soil observations within the top 12 inches. Use most recent National Technical Committee for Hydric Soils guidance for regional indicators. ❑A Sandy soil ❑B Loamy or clayey soils exhibiting redoxymorphic features (concentrations, depletions, or rhizospheres) ❑C Loamy or clayey soils not exhibiting redoxymorphic features ❑D Loamy or clayey gleyed soil ®E Histosol or histic epipedon ❑A Soil ribbon < 1 inch ®B Soil ribbon ? 1 inch ❑A No peat or muck presence ®B A peat or muck presence 5. Discharge into Wetland — opportunity metric Check a box in each column. Consider surface pollutants or discharges (Surf) and sub - surface pollutants or discharges (Sub) Examples of sub - surface discharges include presence of nearby septic tank, underground storage tank (UST), etc. Surf Sub ®A ®A Little or no evidence of pollutants or discharges entering the assessment area ❑B ❑B Noticeable evidence of pollutants or discharges entering the wetland and stressing, but not overwhelming the treatment capacity of the assessment area ❑C ❑C Noticeable evidence of pollutants or discharges (pathogen, particulate, or soluble) entering the assessment area and potentially overwhelming the treatment capacity of the wetland (water discoloration, dead vegetation, excessive sedimentation, odor) Land Use — opportunity metric Check all that apply (at least one box in each column). Evaluation involves a GIS effort with field adjustment. Consider sources draining to assessment area within entire upstream watershed (WS), within 5 miles and within the watershed draining to the assessment area (5M), and within 2 miles and within the watershed draining to the assessment area (2M). WS 5M 2M From 80 to < 100 feet ®A ®A ❑A > 10% impervious surfaces ❑B ❑B ®B < 10% impervious surfaces ❑C ❑C ❑C Confined animal operations (or other local, concentrated source of pollutants ❑D ❑D ❑D ? 20% coverage of pasture ❑E ❑E ❑E ? 20% coverage of agricultural land (regularly plowed land) ❑F ❑F ❑F ? 20% coverage of maintained grass /herb ❑G ❑G ❑G ? 20% coverage of silvicultural land characterized by a clear -cut < 5 years old ❑H ❑H ❑H Little or no opportunity to improve water quality. Lack of opportunity may result from hydrologic alterations that prevent drainage or overbank flow from affecting the assessment area. 7. Wetland Acting as Vegetated Buffer— assessment area condition metric 7a. Is assessment area within 50 feet of a tributary or other open water? ®Yes ❑No If Yes, continue to 7b. If No, skip to Metric 8. Wetland buffer need only be present on one side of the water body. Make buffer judgment based on the average width of wetland. Record a note if a portion of the buffer has been removed or disturbed. 7b. How much of the first 50 feet from the bank is wetland? Descriptor E should be selected if ditches effectively bypass the buffer. ®A ? 50 feet ❑B From 30 to < 50 feet ❑C From 15 to < 30 feet ❑D From 5 to < 15 feet ❑E < 5 feet or buffer bypassed by ditches 7c. Tributary width. If the tributary is anastomosed, combine widths of channels /braids for a total width. ❑ <_ 15 -feet wide ®> 15 -feet wide ❑ Other open water (no tributary present) 7d. Do roots of assessment area vegetation extend into the bank of the tributary/open water? ®Yes ❑No 7e. Is stream or other open water sheltered or exposed? ®Sheltered — adjacent open water with width < 2500 feet and no regular boat traffic. ❑ Exposed — adjacent open water with width ? 2500 feet or regular boat traffic. 8.

Notes Assessment area appears to receive overbank flooding during above normal rainfall. The entire upstream watershed draining to the assessment area appears to be within 2 miles. A wastewater treatment plant accounts for a large portion of the upstream watershed. On the eastern side of the tributary, the WWTP has removed the buffer. The size of this assessment area is equal to the size of the wetland type. The AA and WT are part of a much larger wetland complex, but the width of the WC at the AA is equal to the width of the AA perpendicular to the topographic contours at the AA. This assessment area appears to have been logged in the recent past (abundant saplings and shrubs but few large canopy trees). There are many snags, but they are <12 inches DBH.

Lower Cape Fear Mitigation Bank, White Springs Tract: 01 -09 -117 Natural Communities: Orange Mucky mineral soils in a low ridge- and -swale system and shallow Carolina bays, in a mosaic with Wet Pine Flatwoods, Pine Savanna, High Pocosin, and sandhills. Open canopy of Pinus serotina. Gordonia lasianthus is present in the canopy in some areas. Magnolia virginiana and Persea palustris occur in the understory. 12390 Pond pine woodland Dense shrub layer dominated by Lyonia lucida and Ilex glabra, with N/A N/A 2006 -04 -25 Medium Cyrilla racemiflora, Clethra alnifolia, Ilex coriacea, Vaccinium corymbosum, and Smilax laurifolia common. All of the area appears intact in 1998 and 2005 aerial photos. The community center block was surveyed in 2006, other portions were visited in 2002, and previous extensive survey was done in 1987. Fairly deep peat deposits in a complex of Carolina bays. The pines are somewhat patchy but sparse overall. Plot 1 -1201 had 14 trees in a 10x10 meter area. Plot 1 -1200 had only 8. The shrub layer is very dense, 6 -8 feet tall. Lyonia lucida is strongly dominant. There is a little Ilex coriacea and a few Ilex glabra, Cyrilla racemiflora, and Persea palustris. Dead twigs are extremely abundant, and some of the major branches had died. The shrubs were tall and spindly, and clearly grew up as an even -aged stand after an intense fire. It is 10208 High pocosin likely that most or all of the pines date from the same fire. The N/A N/A 2008 -05 -30 High ground is hummocky, with thick litter (Schafale 2008). Earlier general surveys found similarly sparse Pinus serotina with a few Gordonia lasianthus and Magnolia virginiana. Ilex glabra, Cyrilla racemiflora, and Zenobia pulverulenta are more abundant elsewhere, though Lyonia lucida still dominates. Woodwardia virginica and Smilax laurifolia are abundant. Some of the bay interiors appear on aerial photos to be Low Pocosin, but this has not been verified. APPEARS INTACT ON 1998 DOQQ. FAIRLY EXTENSIVE OCCURRENCE IN GOOD CONDITION.

Federal Species Of Concern "....the Service is discontinuing the designation of Category 2 species as candidates in this notice. The Service remains concerned about these species but further biological research and field study are needed to resolve the conservation status of these taxa. Many species of concern will be found not to warrant listing, either because they are not threatened or endangered or because they do not qualify as species under the definition in the [Endangered Species] Act. Others may be found to be in greater danger of extinction than some present candidate taxa. The Service is working with the States and other private and public interests to assess their need for protection under the Act.

Our files indicate that Reeves African Methodist Episcopal (AME) Zion Church (BW 257) is located on the northwestern edge of the " Sneeden" tract (see enclosed map). This church has been determined eligible for listing on the National Register of Historic Places. Due to this property's eligibility, we need more information about the project which you are planning. Please provide the following: ♦ Specific details about the plans for this property. ♦ Any site and architectural drawings for the tract. There are no known archaeological sites within the proposed project area. Based on our knowledge of the area, it is unlikely that any archaeological resources that may be eligible for inclusion in the National Register of Historic Places will be affected by the project. We, therefore, recommend that no archaeological investigation be conducted in connection with this project. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.

LOWER CAPE FEAR UMBRELLA MITIGATION BANK WHITE SPRINGS TRACT BRUNSWICK COUNTY, NC DRAINMOD ASSESSMENT I. Introduction On behalf of the bank sponsor, Tri -Coast Properties, LLC, Land Management Group, Inc. (LMG) has prepared the following DrainMod assessment for the Lower Cape Fear Umbrella Mitigation. The White Springs Tract property is located immediately northeast of the intersection of NC Hwy 87 and 130 Highway (Brunswick County), NC. The site is bounded to the east by Sunny Point Terminal. The site has been historically managed for silvicultural production since the early 1970's. Intensive site management practices (including the ditching and conversion to loblolly pine plantation) has resulted in the loss and /or degradation of wetland functions on the site. Site - specific soils information, current drainage conditions, and geomorphological data were used to perform DrainMod computer modeling. DrainMod is a field -scale hydrologic model originally developed for the design of subsurface drainage systems. Its application is now widely used for the purposes of evaluating lateral drainage effects of existing ditches and modeling for wetland restoration purposes. The model incorporates long -term climatological data in conjunction with site - specific model inputs. For the White Springs Tract site, the model has been run utilizing field- measured conductivity rates for various soil series identified by licensed soil scientists of LMG. In order to determine the drainage response relative to existing ditch size, multiple DrainMod analyses were conducted utilizing various input parameters. These models incorporated typical channel geometry observed for the large collector canals and smaller, lateral ditches. DrainMod utilizes Reference Wetland Simulation (RWS) in which typical reference soil and drainage inputs are used to determine minimum hydrology requirements satisfying 404 wetland jurisdictional criteria. Separate runs are then analyzed to determine current drainage alterations. The results of these evaluations were used to identify the lateral drainage effects of ditches occurring within the White Springs Tract property. II. Site Conditions The White Springs Tract site (approximately 84 acres) consists predominantly of former headwater wetland flats that drain to the Cape Fear River. These non - riparian wetlands have been historically ditched as part of a prescribed silvicultural management plan implemented by International Paper Company during the 1970s. The network of 1 drainage ditches serve to lower groundwater tables and intercept surface water — thus compromising the ecological functions (i.e. nutrient /sediment retention, flood attenuation, etc.) characteristic of headwater wetlands. The major outlet diverts flow to the southeast into the Cape Fear River. The site consists predominantly of drained hydric soils characteristic of broad interstream flats of the outer Coastal Plain. Representative mapped soil units include Murville fine sand, Leon sand, and Foreston fine sand. These series are poorly drained to very poorly drained soils characteristic of non - riparian wetlands. Areas of unmapped, very poorly drained organic soils occur within wetlands onsite. These soils most closely resemble the Croatan soil series. Approximately 6,000 linear feet of open ditching currently exists throughout the site. Areas located within deeper depressions within the landscape still retain wetland hydrology. III. Drainage Modeling DrainMod software, an approved hydrologic modeling tool (USACE, 2008), was utilized to determine the extent of drainage throughout the site. This software models the cumulative effects of parallel drainage features using long -term climate data and user supplied inputs. The user supplied inputs allow for site - specific drainage spacings, ditch depths, and soil conductivity rates to be modeled over multiple decades. This long -term approach provides information on the hydrology of the site in a variety of climatic conditions, which can aid in the determination of the effective lateral drainage distance of a ditch. The calibration process consisted of adjusting soil property inputs so that model predictions match, as closely as possible, the measured water table fluctuations in response to measured rainfall and calculated evapotranspiration (ET). Soil properties vary between soil series, and from point to point within a given soil series. Calibration provides a method of determining the field effective soil property values for each observation well. The DRAINMOD model was calibrated separately for each transect location using a short -term record of observed weather data and water table measurements recorded across a 4 -month period from January 1, 2010 until April 31, 2010. This period was chosen because the precipitation record began above normal, declined through normal conditions for several weeks and then dropped below the normal range. The full range of rainfall totals during this period is provides the calibration procedure its greatest accuracy when fitting the model to a wide range of soil moisture levels. The calibration of the model utilized site - specific data for soil horizon depths and conductivity rates. In order to obtain conservative results, lower conductivity rates were used when ranges were provided (see below). All inputs, with the exception of the drain spacing, remained constant throughout the calibrations and are shown in Table 1. The growing season is considered year -round and the critical period was set at 14 days. 2 Climate data from Wilmington, N.C. were used for modeling input based upon proximity of this weather station to the mitigation site. Table 1.

Surface Storage 1.2 3 Depth of flow to drains 1.2 3 Wilmington, Climate Data NC Time Period 1965 -1995 Critical Water Table Depth 30.5 cm Critical Duration 12 days DrainMod utilizes Reference Wetland Simulation (RWS) in which typical reference soil and drainage inputs are used to determine minimum hydrology requirements satisfying 404 wetland jurisdictional criteria. Separate runs are then analyzed to determine current drainage alterations. Threshold settings for each of different configurations were based on the number of consecutive days necessary to meet the wetland hydrology criteria. This criteria states that a site must exhibit water table depths within 12 inches of the surface for a 14 consecutive number of days of the growing season. When these conditions are met for >50% of the years during a given study, the site is considered to be jurisdictional wetlands. The results from the different configurations are presented in Table 2. Based upon these results, a 4 -ft ditch effectively lowers the water table for a total distance of 130 -ft 3 in a Murville soil. These conditions mimic the existing network of lateral drainage ditches found throughout the existing silvicultural stands. Model results for the existing collector canals depths show a potential lateral drainage effect of up to 130 ft. Based on the combination of field observations, soil borings, and DrainMod results approximately 63 acres (CP TO PROVIDE SPECIFIC ACREAGE BASED UPON JD) of the remaining tract appear to have been effectively drained and are considered suitable for wetland restoration (see Figure 13 of the Wetland Mitigation Plan). Note that these investigations also provide evidence of hydrologic modifications outside of the 1400' offsets, although these areas may still maintain water table depths sufficient to meet the wetland hydrology criteria.
