The Bank is proposed as a multi -phase project: eight sites constitute "Phase I "; all future phases will consist of sites that have not yet been secured or identified. The accompanying Prospectus provides preliminary descriptions of existing and proposed conditions at all Phase I sites. In addition, the Prospectus discusses a series of general provisions and requirements of the proposed umbrella banking instrument. We recognize that an umbrella stream mitigation bank is an uncommon occurrence in the Wilmington District. We have therefore attempted to provide as much information as possible at this stage in the process. We hope that you find the Prospectus's contents adequate and complete. We are prepared to assist you in coordinating site visits for our Phase I properties. Please keep in mind that there are eight Phase I sites; therefore the field visits will likely require two days. Please reach out to us with suggested dates at your earliest convenience.

Restoration Systems LLC vi Cape Fear 02 Umbi ella Pi ospectus I INTRODUCTION Restoration Systems, LLC ( "the Sponsor ") is ,pleased to propose the Cape Fear 03030002 (Cape Fear 02) Umbrella Mitigation Bank ( "the Bank "). The proposed umbrella structure of the Bank is designed to initially permit the establishment of eight stream mitigation sites (collectively referred to as "Phase F'),, while enabling the establishment of future mitigation sites not yet identified All Phase I sites are located in North Carolina and consist of the following- 1) Motes Creek in Alamance County, 2) Benton Branch in Caswell County, 3) Orphan Creek in Alamance County, 4) Chico Branch in Rockingham County, 5) Maple Hill Farm in Alamance County, 6) Major Hill in Alamance County, 7) Rocky Top in Alamance County, and 8) Slingshot Creek in Rockingham County (Figure 1; Table 1).

Motes Creek is located approximately 8 miles southeast' of Burlington Benton Branch is located approximately 4 miles north of Burlington. Orphan Creek is located approximately 2 miles north of Saxapahaw and 7 miles southeast of Graham. Chico Branch is located approximately 6 miles south of Reidsville Major Hillis located approximately 5 miles southwest of Saxapahaw and 3 miles east of Snow Camp Maple Hill Farm is 16cated approximately 4' miles west bf Saxapahaw -and; 9 - miles- ,south. of- Graham: Rocky Top .,is - located - approximately- 6 miles southwest of, °saxajiahaw and= 2 =miles east of --Snow Camp.

Phase I is described in this prospectus and, if Restoration Systems LLC 3 Cape Feat 02 Umbi ella Prospectus d: approved, will serve as the Bank's first source of mitigation credit The Sponsor also proposes the incorporation into the Bank of additional sites not yet identified (within the Geographic Service Area described in the next section), following Interagency Review Team ( "IRT ") review and approval 2.2 Credit Determination Credit for Phase I, and all additional phases, shall be based on the U S Army Corps of Engineers (USAGE) most current mitigation credit determination methodology. Presently, the USACE is utilizing the Stream Mitigation Guidelines (USACE 2003) to quantify mitigation project credit potential If other methods are released and become de facto requirements for stream mitigation projects in the USACE, future phases will utilize these methods, as appropriate. 2.3 Riparian Buffer and Nutrient Offset Credits In April 2013, the Sponsor+and.the North Carolina Department -of Environment and Natural °Resources ( "NCDENR ") entered into an Agreement to Establish an Umbrella Mitigation Banking Instrument in the Cape Fear River Basin for Riparian Buffer and Nutrient Offset Mitigation Credits Pursuant to the Jordan Lake Nutrient Strategy ( "Buffer UMBI ") The Sponsor may choose to generate and sell buffer or nutrient credits from any site(s) permitted under the UMBI proposed here Such generation and sale of buffer or nutrient credits must be approved by NCDENR, and shall be pursuant to all terms and conditions of the Sponsor's Buffer UMBI 2.4 Credit Release Schedule Credits generated by actions, described and "approved in the Bank's final UMBI shall be released,in predetermined increments according to the milestones agreed to by the Sponsor and the'I,RT in the UMBI's credit release schedule. The Sponsor will use the credit release schedule detailed.for stream mitigation banks in USACE (2013) 3 GEOGRAPHIC SERVICE AREA AND USE OF CREDIT'S Located, within the Piedmont level III ecoregion and the Upper Cape Fear River basin, the Bank's geographic service area ( "GSA ") is defined. by the United States Geological Survey (USGS) 8 -digit Hydrological Unit Code ( "HUC ") within which the Bank's sites are located, the Cape Fear 02 (Figure 3) The Bank's credits are proposed to be used to offset unavoidable, permitted impacts within the Bank's GSA Use of the Bank's credits outside of its GSA may be permissible with approval by the USACE, which will be considered on a case -by -case basis. Restoration Systems LLC 4 Cape Fear 02 Unibiella Prospectus 4 WATERSHED CONSIDERATIONS 4.1 Watershed Environmental Concerns and Mitigation Needs The Cape Fear River basin is one of four rivers in North Carolina completely contained within the state's boundaries. Comprised of five major drainages —Haw River, Deep River, Northeast Cape Fear River, Black River and the Cape Fear River — the basin drains portions of 26 counties and 115 municipalities with a total of 6,386 stream miles The most populated portions of the basin are located in the Triad, the Triangle, Fayetteville, and Wilmington (NCDWQ 2005). Nearly all of the Cape Fear 02 drains into B ,Everett Jordan Lake ( "Jordan Lake "), which is designated as impaired due to excessive levels of chlorophyll a according to state water quality standards Stressors to Jordan Lake's water quality are associated with nitrogen and phosphorus inputs from point sources, especially municipal wastewater, and non -point sources such as urban stormwater runoff'arfd rural agricultural runoff Most of the impaired streams, in the Cape Fear- 02 are located in heavily urbanized,areas Between the 2000 and 2010 censuses, the Cape Fear 02 population increased approximately 17 percent (Table 5). The general trend of population growth appears to be continuing according to recent population estimates, which indicate Guilford, Orange, Chatham and Durham counties are all growing at faster annual rates than the state's 102 percent (,USCB 20,13) These data suggest land development activities will increase in frequency, as will aquatic ecosystem impacts related to such development Therefore, there is an immediate and prolonged need for compensatory stream mitigation in the watershed. Of further benefit, aquatic ecosystem restoration projects are capable of reducing nutrient loading in sensitive downstream receiving waters such as Jordan Lake.

Bass Mountain and Cripple Creek are the only active stream mitigation banks in the watershed Current stream mitigation credit inventory relative to North Restoration Systems LLC 5 Cape Fear 02 Umbrella Pi ospectW, Carolina Ecosystem Enhancement Program ( NCEEP) demand is exceptionally low Since 2002, the NCEEP has requested 155,000 Stream Mitigation Units (SMUs) in the Cape Fear 02 (Table 6) Available inventory,is approximately 482 SMUs Table 6 NCEEP Stream Mitigation Requests for Proposals in Cape Fear 02 Request For Proposals SMU&Requested October 26, 2005 90;000 November 22, 2006 17,000 November 24, 2009 5;000 October 30; 2013 43,000 Total 155,000 4.2 Bank Site Selection Based on the analysts presented in Section 41, the Cape Fear 02 was targeted as a watershed in need of stream mitigation The Sponsor and its consultant, Axiom Environmental, Inc (Axiom), conducted a search for sites possessing stream restoration and enhancement opportunities. Identified sites were prioritized based on geomorphic condition and land use, and the necessary landowners were contacted to gauge their interest in participating ,in a stream mitigation project. Sites with willing landowners were then pursued further As real estate in the area is generally well subdivided, many of the identified opportunities are not currently feasible because such sites require the cooperation' of several landowners in order to achieve sufficient ecological and economic-scale. Therefore, selection of the Phase I properties was based on a combination of geomorphic condition, land use, and the willingness of landowners to participate 5 OWNERSHIP AND LONG -TERM MANAGEMENT The Phase I properties are an assemblage of portions of larger holdings currently owned by the following people, or organizations, Motes Creek - Thomas, Roger, and Patricia Dodson of Alamance County; Benton Branch - Dennis Simmons of Caswell County; Orphan Creek - Mr and'Mrs Williamson of Alamance County, Chico Branch - Billingsley & Associates of Rockingham County; Major Hill - Jim Lamm of Alamance,County; Maple Hill Farm'- Joe and Tish Murray of Alamance County,; Rocky Top - Jim Lamm of Alamance County; and Slingshot Creek - Robert Wheless of Rockingham County Hereafter, these owners will collectively be referred to as "the,Landowners. The Sponsor and the Landowners have executed separate Agreements for Purchase and Sale of Conservation Easements coveting approximately 19 -acres along Motes Creek, 30 -acres along Benton Branch, 14.5 -acres along Orphan Branch, 8 -acres Restoration Systems LLC 6 Cape Fear 02 Umbi ella Pi ospectus along Chico Creek, 11 1 -acres along Maple Hill Farm, 10 -acres along Major Hill, 5 2- acres along Rocky Top, and 13 -acres along Slingshot Creek. Following USACE approval of the UMBI and the Phase I Mitigation Plan, the Sponsor will exercise its rights provided under the above - referenced agreements. The Phase I properties will be protected in perpetuity by conservation easements approved by the USACE. At a minimum, conservation easements will be written to prohibit incompatible uses that might jeopardize objectives of the Bank During the operational period of each site,:the Sponsor may hold the conservation easements. Once a Bank site is closed out, easements will be transferred to a-qualified land trust, such as ,the North Carolina Wildlife Habltat,Foundatlon, to be held in +perpetuity The Sponsor will provide the land trust with a f nancial,sum, in an amount agreeable to both parties, appropriate for the long -term stewardship of the sites During the operational period ,of a Bank site, the Sponsor will be responsible for management actions Following Bank close out, the Landowners will serve as long- term managers of the sites, and the land trust holding conservation easements will routinely monitor the sites to ensure the Bank's conservation easement terms are not violated Other long -term management responsibilities will include protecting the sites from encroachment, trespass, clearing, an_d other violations that interfere .with conservation purposes. Fencing, suitable to prevent livestock grazing within easement boundaries, will be constructed as necessary Conservation easement boundaries will be clearly�marked prior to transfer. 6 QUALIFICATIONS,OF'SPONSOR Restoration Systems is an environmental restoration, mitigation banking and full - delivery mitigation firm founded in 1998 The firm was formed to improve the quality of environmental restoration and mitigation by locating and acquiring the best available sites, planning restoration using proven science, and constructing sites with the most qualified contractors Restoration Systems' staff has been involved in environmental mitigation and mitigation banking since '1992 Project managers have more than 80 years of experience in resource evaluation, environmental restoration, and mitigation implementation The company employs 9 permanent staff members based in Raleigh, North Carolina. Corporate experience with the principals began with completion of the state's full - delivery, mitigation project in 1997, the Barra Farms Mitigation Bank (623- acres), the, subsequent Bear Creek —Mill Branch Mitigation Bank in 2001 (450- acres), and Sleepy Creek Mitigation Site (55&-acres) The firm then performed all of the off -site mitigation (7500 -LF of stream restoration and 10 -acres of wetland restoration) for the Piedmont Triad International Airport Authority. Restoration Systems has implemented projects for the NCEEP, formerly the North Carolina Wetland Restoration Program; including the removal of the Carbonton and Restoration Systems LLC 7 Cape Fear 02 Umbi ella Prospectus Lowell Mill dams in the Cape Fear and Neuse River basins (132,000 -LF), the Haw River Wetland Restoration Site (34- acres, Cape Fear), -the Elk Shoals.

Based on regional curves (Harman et al 1999), the bankfull discharge,for a 0,71- square mile. watershed is expected to average 70- cubic feet per second (CFS). Based on empirical evidence a bankfull discharge of 70- CFS is expected to occur approximately every 1.3 to 15 years (Rosgen 1996, Leopold 1994) 9.1.6, FluvialZeomorphology , Currently; channels'targeted for restoration are characterized as entrenched and /or incised G -type or C -type channels with little to no sinuosity, little to no riffle -pool morphology, oversized cross - sectional areas, and no access to floodpl'ains during high discharge events (Bank Height, Ratio (BHR) range > 1.3 to 2.4). Sinuosity was measured at 1.05 from topographic surveys, aerial photography, and visual observation during field surveys. In general, sediment and nutrient inputs, channel incision and straightening, livestock trampling, removal of cobble substrate, aggradation of silt and sand, and removal of woody vegetation have impacted Motes Creek site streams. 9.1.7 FEMA Inspection of the FEMA Flood Insurance Rate Map 371O9811O0J, Panel 9811, effective September 6, 20,06, indicates that -Motes Creek streams are not located in a Special Flood Hazard Area, and the project should not alter FEMA flood zones Therefore, a "Conditional Letter of Map Revision" (CLOMR) is not necessary for this site 9.2 Benton Branch The Benton Branch site is characterized by disturbed forest and agricultural1arid used for livestock grazing and hay production (Photo 2). The main hydrological features include Benton Branch and six UTs to Benton Branch. Several of these streams have impoundments in the headwaters reducing the frequency and Restoration Systems LLC 12 Cape Fear 02 Umbt ella Prospectus duration of channel - forming discharges. The proposed conservation easement area contains approximately 30 -acres (Figure 5A) 9.2.1 Physiography, Topography, and, land Use The Benton Branch site is located in the Southern Outer Piedmont.

In addition, benthic macroinvertebrate samples collected in the upper reaches of UT 4 using the Qual -4 technique support a perennial flow regime designation (stonefly larvae) UT 2 and UT 3 are not mapped by the USGS, however-, field evidence — including benthic macro inverteb rate samples, NCDWQ Stream Identification Form [v411] scores, and evidence of stream flow during field visits — indicates the channel's are intermittent to perennial UT 1, UT 2, and UT 3' all 'exhibit characteristics of perennial flow in the upper reaches However, ponds upstream from the stream origin point, low slope of floodplain, livestock impacts to channels, and antropogenic alterations to the floodplain and channels have resulted in loss of stream channel morphology in the downstream reaches. This hydrophysiographic region is characterized by moderate rainfall with precipitation averaging 43 4- inches per year (based on data provided by, NOAA 2014) Site discharge is dominated by a combination of up_ `stream basin catchment, groundwater flow, and precipitation Based on regional curves, the bankfull discharge for a 0 3- square mile and 9 1- square mile. watershed are expected to average 7.8 and 439 -CFS, respectively (Harman et al. 1999).

Restoi aeon Systems LLC 15 Cape Fear 02 Untbt ella Prospectus 9.2.6 ,Fluvial,Geomorphology Currently, two distinct stream types characterize channels targeted for restoration One is an entrenched and`` /or incised G -type or F -type channel with sinuosity affected by bank erosion and hoof shear. Riffle -pool morphology has been compromised by sedimentation and bank collapse due to a lack of deep. Footed vegetation These channels are oversized with no access to floodplains during high - discharge events (BHR = 3.6) A second stream type ,includes streams without existing channels due to aggradation resulting from livestock trampling, vegetative clearing, removal of channel substrate, and channel rerouting Headwater ponds further affect some of the channels in this category. 'Ponds in the upper reaches of UT 1, UT 2, and UT 3 appear to attenuate storm flows, thereby reducing sediment rnobilization Reduced sediment transport and intensive trampling of channel bed and banks by livestock has produced aggraded channels characterized as wide, compacted sloughs without defined beds or banks. 9.2.7 FEMA Inspection of the FEMA Flood Insurance Rate Map 371089600K, Panel 8960, effective September 28, 2007, indicates that Benton Branch, UT 3, and associated floodplains are located within a Zone AE flood area. Therefore, a HEC -RAS analysis will be completed on the existing and proposed conditions of Benton Branch and its tributaries that enter the Benton Branch floodplain to assess hydraulic performance. As per N.C. Floodplam .Mapping requirements, a Conditional Letter of Map Revision (CLOMR) will need to,be�prepared for the site. The CLOMR includes written documentation of modeling, preparation of topographic work, maps, annotated FIRM or Floodway Maps, FIRM Flood Profiles and Data Tables The CLOMR will be sent to, Caswell County for approval and signature, and then the CLOMR will be sent to FEMA for review, and,approval The CLOMR approval prpcess will take 3 -6 months The.

Primary activities designed to restore`Phase I channels include belt -width preparation ' and grading, channel excavation, installation of channel plugs, backfilling of abandoned_ channels.. Installation of piped channel crossings, and vegetative planting.;,, - 10.3.1 Belt width Preparation and Grading n I. Care will`be taken fo'avoid the removal of existing, deeply "rooted vegetation within, the belt -width corridor, which" often provides channel stability. Material excavated `during grading will be, stockpiled immediately adjacent io channel segments to „be abandoned and backfilled'following stream diversion. Restoratloll Systems,LLC 41 Cape Feai 02 Umbrella Prospectus Spoil material may be placed to stabilize temporary access roads and to .minimize compaction of the underlying floodplam. However, all spoil will be removed from floodplain surfaces upon.completion of construction activities After preparation of the corridor, the design channels and updated profile surveys will be developed, and the locations of each meander wavelength will be plotted and staked along the profile Pool locations and other channel features may be modified in the field based on local variations in the.floodplam profile 10.3.2 Channel Excavations Channels will be constructed within the range of values developed during detailed restoration planning. Regional curves and /or reference stream reaches (see Section 10 1 1) will be used to develop various stream geometry attributes Stream banks and local belt -width areas of constructed channels will be immediately planted with shrub and herbaceous vegetation to initiate stability, preventing unintended erosion Deposition of shrub and woody debris into and /or overhanging the constructed channels will be used to further increase each channel's resistance to shear stress Particular attention will be directed toward providing vegetative cover and root growth along the outer bends of each stream meander. Live willow stakes will be purchased and /or collected on -site and inserted through the root /erosion mat into underlying soils. 10.3.3 Channel Plugs Impermeable plugs willbe installed along abandoned channel segments; The plugs will consist of low - permeability materials or hardened structures designed -to, be of sufficient strength to withstand the erosive energy of surface flow events across each site. Dense clays, which may be imported from off -site if necessary, Will be compacted within each channel for plug construction. Each plug will be of sufficient width and depth to form an imbedded overlap in the existing banks,and bed. 10.3.4 Channel Backfilling After impermeable plugs have been installed, abandoned channelswill be backfilled Stockpiled materials will be pushed into abandoned channels. Suitable material used for backf►lling may be derived from c n -site or off -site sources. Vegetation debris (e&, root mats, top soils, shrubs, woody debris, etc.) will be 'redistributed across the backfill area upon completion 10.3.5 Piped Stream Crossing Landowner uses will sometimes necessitate the installation of piped channel crossings to allow access to portions of the property otherwise isolated by stream restoration activities Piped crossings will be constructed with pipes sized to adequately pass anticipated stormwater flows with hydraulically stable riprap or other suitable rock. Pipes will be large enough to handle the weight of anticipated vehicular traffic. Approach grades will be at an approximate 10:1 slope and Restoration Systems LLC 42 Cape Fear 02 llmbi ella Pi ospectus constructed on hard, scour - resistant crushed rock or other permeable material free of fines 10.3.6 In- stream Structures The use of in- stream structures for grade control and habitat are essential for successful stream restoration. In- stream structures maybe placed °in the channel to elevate local water surface profiles, potentially flattening the water energy slope or gradient. The structures will likely consist of log /rock cross -vanes or log /rock 1- hook vanes designed primarily to direct stream energy into the center of the channel and away from banks In addition, structures will be placed m relatively straight reaches to provide secondary (perpendicular) flow cells during bankfull events. Log vanes may also be used to ,direct high- velocity -flows during bankfull ,events toward the center of constructed' channels:'Log vanes will be constructed utilizing large tree trunks harvested on -site or imported from off -site as necessary Tree stems harvested for a log cross -vane arm must be long enough to be embedded into the stream channel and extend, several feet into the floodplain Logs will create an arm that slopes from the center of the channel upward to each stream bank at an angle or 20 to 30- degrees A trench will be dug into the stream channel that is deep enough for the head of the log to be at or, below, the channel invert. The trench is then extended into the floodplain and the log -is set into the trench such that the log arm is below the floodplain elevation If °the log is not of sufficient.siz_e to completely ,block,stream flow (gaps occur between the log and channel bed), a footer log will be installed beneath the header log. SuppofVpilmgswill then be situated at the base of the log and at the head of the log to hold the log in place. Once these vanes are in place, filter fabric is toed into a trench on the upstream side of the vane and draped over thfe structure to force water over the vane The upstream side of'the structure is then backfilled with suitable material. Drop structures will be necessary at the outfalls of some constructed channels to match preconstruction elevations. Drop structures will be constructed out of TerraCell, or other suitable materials, depending upon anticipated scour from the restored stream channels. The structures will be constructed to resist erosive forces associated with hydraulic drops TerraCell is a lightweight, flexible mat made of high- density, polyethylene strips- The strips are bonded together to form a honeycomb configuration The honeycomb mat is fixed in place and filled with gravel or sand Material in the TerraCell structure may be planted with grasses and shrubs for additional erosion protection. The TerraCell structure will form a nickpoint that approximates geologic controls in streambeds. 10.4 Riparian Restoration Restoration of floodplain forest and streamside habitat allows for development and expansion of characteristic species across the landscape. Ecotonal changes between community types contribute to diversity and provide secondary benefits, such as Restoration Systems LLC 43 Cape Fear 02 Umbrella Pi ospectus enhanced feeding and nesting opportunities for mammals, birds, amphibians, and other wildlife. Planted streamside trees and shrubs will include species with high value for sediment stabilization, rapid growth rates, and the ability to Withstand hydraulic forces associated with bankfull and overba_ nk ,flow events Streamside trees and shrubs will be planted within 15 -feet of the channel throughout the meander beltwidth Shrub elements will be planted along reconstructed stream banks, concentrated along outer bends. Deeply rooted' riparian vegetation will be restored as needed at all Phase I and future sites Planting vegetation on cleared stream banks is proposed to reestablish native /historic,community patterns within the stream corridor, as well as associated side slopes and transition areas. Revegetating floodplains and stream banks will provide overall system `stability, shade, and wildlife habitat. In addition, viable riparian communities will' improve system biogeochemical function by filtering pollutants from overland and shallow subsurface flows and providing organic materials to adjacent stream channels Variations in vegetative planting will occur based on topography and hydraulic condition of soils. Vegetative species composition will be based on RFEs, site - specific features, and community descriptions from Classification of the Natural Communities of North Carolina (Schafale and Weakley 1990) Community associations to be utilized include: 1) Piedmont /Low Mountain Alluvial Forest, 2) Dry -Mesic Oak- Hickory Forest and 3) Streamside Assemblage A list of species organized by Schafale and Weakley (1990) communities is presented below. This list is for planning purposes only Final planting may include some or all of the species below In addifion, other species may be added if,appropriate and available Piedmont Alluvial Forest 1 Sycamore (Platanus occidentabs) 2 American elm (Ulmus americana) 3 Hackberry (Celtis laevigata) 4.

Stream enhancement II will extend a minimum distance of 50 -feet from the top of stream banks These measures are expected to facilitate stream recovery and prevent further degradation of the streams 11 MONITORING PLAN The Bank's`performance standards and monitoring plan will, be based on the USACE (2013) guidance document titled, Monitoring Requirements and Performance Standards for Compensatory Mitigation in North Carolina. In general, the monitoring program will be implemented for 7 years with an opportunity for an, early termination after 5 years if a site's performance standards, as, set forth in USACE (2013), are met Additional monitoring of each site, aside from the Bank's performance standards, will occur -to identify ,areas to be treated by the Adaptive Management and Remedial Measures Plan (see Section 12) 11.1 Stream Monitoring Stream monitoring protocols. -will be developed for all reaches involving Stream Restoration, "Enhancement II, and Enhancement I with in- channel work Protocols will include collection of the following: longitudinal profile (collected' as part of a Restoration Systems LLC 45 Cape Fear 02 Umbrella Prospectus sites' as -built surveys), permanent channel cross - sections, bank pins on predetermined outside meander bends, and crest gauges to monitor frequency,and magnitude of bankfull events Visual assessments will be conducted by walking the length of each channel. Preconstruction and post - construction photographs' will 'be compiled 11.2 Vegetation Monitoring Restoration monitoring procedures for vegetation are designed in accordance,with CVS -EEP Protocol for-Recording Vegetation Level 1-2 Plot Sorripling Only (Version 4:2) (Lee et al. 2008) After planting has been completed in winter or early spring, an initial evaluation will be performed to verify planting methods and to determine initial species composition and density Supplemental planting and additional site modification will be implemented'if necessary. During the first year, vegetation will receive Visual observation on a periodic basis to ascertain the degree of over'toppin'g'of planted elements by nuisance species, and quantitative sampling will occur between 'September 1 and September 30. Subsequently, quantitative sarnpIfng,of vegetation will be performed between July 1 and leaf'drop for'eachgrowing season until vegetation success criteria are achieved. During quantitative sampling in early fall of the first year, a minimum of 4 plots '(10 meters square) or approximately 2 percent of a site's easement area, whichever,is greater, will be randomly placed across each site. In each sample plot, vegetation parameters to be monitored` and reported inclue species, count, height, date of planting, and grid location of each planted stem Volunteer species encountered during monitoring will be counted, identified to species level, measured, And recorded. 11.3 Visual Monitoring Visual monitoring of general site conditions that may or may not be part of „stream and vegetation monitoring protocols will be conducted at, least twice during each monitoring year: One visual inspection can be completed during stream and /or _ r y vegetation monitoring 'The other inspection will occur independently and must be separated by at least- 5 months Monitoring will be conducted by traversing the entire site to identify and document areas of low stem density, poor plant vigor, prolonged inundation, native and exotic invasive species, beaver`activity, excessive herbivory,. easement encroach'merit, indicators of livestock access, and other areas of concern. 11.4 Water Quality and Macroinvertebrate Monitoring Per USACE (2013), water quality and macro invertebrate monitoring will be conducted as appropriate for each site ,to document fluctuations in various water quality parameters and'inacroinvertebrate communities. Protocols for water quality and macroinveriebrate monitoring will be developed for all reaches involving Restoration Systems LLC 46 Cape Fear 02 Umbrella Prospectus Stream Restoration, Enhancement I, and Enhancement II with, in-channel work. As streams are products of their watersheds, and upstream pollution and land use can negatively affect a site's water quality, the results of this particular, part. of the Monitoring Plan may not demonstrate ecological improvements at a, given site Therefore, these data will not be tied directly to the UMBI's performance standards However, positive results could be useful in determining if a particular site has met its goals and objectives 11.4.1 Water Quality Monitoring Water quality monitoring will be conducted once to establish baseline conditions and at least twice during each monitoring year Monitoring should be repeated at the same times and during normal flow conditions each year to limit seasonal and hydrological variability. Each bi- annual monitoring event will be separated by 5 or more months Water quality parameters to be sampled include pH, temperature, dissolved oxygen, and conductivity, which will be sampled at two locations in each tributary exceeding 500 -LF in order to capture channel - specific input and output values 11.4.2 Macroinvertebrate Monitoring M acro invertebrate sampling will be conducted once before construction (baseline conditions) and once during monitoring years 3, 5, and 7. Sampling will be conducted according to the "Qual 4" method described in Standard Operating Procedures for Collection and Analysis of Benthic Macromvertebrates (NCDWQ 2012) In addition, sampling should occur during the "index period" referenced in Small Streams Biocriter►a Development (NCDWQ 2009) Results will be presented on a site - by -site basis and will include a list of taxa collected, an enumeration of Ephemeroptera, Plecoptera, and Tricoptera taxa, and' Biotic Index values. 12 ADAPTIVE MANAGMENT AND REMEDIAL MEASURES An adaptive management plan will be� developed for each site and for the UMBI in general. In the, eyent,momtoring results indicate a site will not meet one or more of its performance standards, remedial actions will be implemented following notification of the UMBI's USACE project manager -, Adaptive management and remedial measures are discussed in general below and will be developed further in the UMBI's Final Mitigation Plan 12.1 Stream Instability If stream monitoring and /or visual monitoring identify stream stability problems that worsen or otherwise, threaten other portions, of a mitigation, site,,repairs'will be made as necessary Persistent problems will be evaluated to determine if design or construction are contributing factors. Should such systemic problems be identified and reasonably determined to be unfixable, the IRT may deride to adjust a site's mitigation credit potential Restoi ation Systems LLC 47 Cape Fear 02 Umbrella Prospectus 12.2 Vegetation Vegetation mortality remedial actions may include ,replanting, and, if needed, corrective measures will be based on a determination of potential reasons for mortality (e g;, portions of site too wet for planted species). Low vegetation vigor remedial actions may include but are not limited to deep ripping, replanting (same or similar species),;m`ow,mg, herbicide application, fertilization, and replantingwith other species possessing condition - specific tolerance. 12.3 Invasive Species In the event that .invasive or otherwise undesirable species —as defined in an appendix to, the "NC,SAM'Users Manual, (NC SFAT 2014) — reasonable efforts will be made- to eradicate or otherwise control ,growth and distribution of the, species across the mitigation site, Such- efforts may involve herbicide applications, mechanical, and /.or hand removal, or prescribed burns. 13 HISTORICALAND ARCHEOLOGICAL INVESTIGATIONS Field visits were conducted at all Phase I sites during the winter, spring, and summer of 2014 to ,ascertain the presence of structures or other features that may be eligible for inclusion on the National Register of Historic Places. No structures were identified within proposed easement boundaries; however, coordination with State Historic Preservation Office will occur prior to construction activities to determine if any significant cultural resources are present 14 Eh DANGERED AND PROTECTED,SPECIES 14.1 Motes Creek, Orphan Creek, and Maple Hill Farm The United States Fish and Wildlife Service does not list any protected species as occurring in Alamance County (USFWS 2014) However, six species are designated as Federal Species of Concern (Table 32) If present, these species are likely to benefit from the restoration efforts Table 32 Federal Species of Concern, Alamance County, NC Common Name Scientific Name Potential Habitat Present American Eel Anguilla rostrata No Carolina Darter Etheostoma collis lepidinion No Carolina Creekshell Vdlosa vaughaniana No Yellow Lampmussel Lampsilis cariosa No Buttercup Phacelia Phacelia,covellei No SweefPinesap Monotropsis odorata No Restoration Systems LLC 48 Cape Fear 02 Umbrella Prospectus 14.2 Benton Branch Two federally protected species are listed as occurring in Caswell County (USFWS 2014)• the James sp►nymussel (Pleurobema collina) and the Roanoke logperch (Percina rex).

Detailed surveys for this species may be required prior to land disturbing activities associated with stream restoration at this site. 14.3.1.4 Preliminary Biological Conclusions Neither the James,spineymussel nor the Roanoke logperch have ranges extending to the site Suitable habitat for the smooth coneflower does not exist at the Chico Creek site. However, suitable habitat for smooth coneflower may exist at the Slingshot Creek site and this project may effect on this federally protected species 15 CONCLUSIONS Restoration Systems, LLC is pleased to offer the Cape Fear 02 Umbrella Mitigation Bank ( "the Bank "). The proposed umbrella structure of the Bank is designed to imfially,permit the establishment of eight stream mitigation sites, comprising Phase 'w I, hile ,enabling the establishment of 'future mitigation sites not yet 'identified.
