The CGMB contains headwater streams of the upper Catawba River Basin. The project area lies just outside a Targeted Local Watershed (TLW) by NC Department of Environmental Quality. The CGMB will serve TLWs in the Catawba basin. The site entrance is at 985 Old US 70, Old Fort, 28762. The center of the project area is roughly centered at Latitude 35.64397 N and 82.19258 N Longitude. A site location map can be found within Exhibit A, the Camp Grier Conceptual Mitigation Plan for the project area. The property and project area slope generally south from the southeast side of the Black Mountains range and makes up part of the boundary between the mountain and piedmont physiographic regions on the flank of the Blue Ridge escarpment. Streams that do not originate within the project area flow from more than 27,000 acres of undeveloped USDA National Forest land. Jarrett Creek flows through the property, and southern portion of the project area. Padgett Branch, its tributaries and its confluence with Jarrett creek, make up the remainder of the project area. Jarrett creek flows in to Mill Creek just south of the property. Mill Creek is a major tributary, and trout fishery, of the South Fork of the Catawba River. The Camp Grier property and project area are surrounded to the west, north, and east by USDA Forrest Service Land. This site is bordered on its remaining southwest, south and southeast sides by private undeveloped and residential properties. The 14-digit Hydrologic Unit Code (HUC) for the site is 03050101010010. The CGMB will presumably serve the area within the eight-digit HUC: 03050101 which extends to the South Carolina state line. The project area will occupy approximately 109 acres within the 650-acre Camp Grier property. Much of the project area has been impacted by logging before 1960 and is currently suffering repetitive and ongoing impacts from camp activities and camp development. Streams within the project appear to have been degraded from their current NC DWR water quality classification by historic excavation, channelization, filling, and stormwater, sediment, and nutrient impacts. The Camp’s current administration recognizes the habitat and water quality need, educational opportunity, and the potential that a mitigation bank could bring to the camp. The board members for the Camp Grier 501 (c) (3) non-profit organization are currently committed to the CGMB project. Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O.

Preservation of headwater streams is proposed above the restored, created and enhanced streams and wetlands thereby protecting the restored environment. The project will result in more than 20,000 linear feet of stream, approximately 0.5 acres of wetlands, and 109 acres of stream and wetland buffer being protected in perpetuity by a conservation easement and Mitigation Banking Instrument (MBI) for the project area. The conservation easement is to be held by a nationally accredited, non-profit regional land trust, that serves North Carolina’s eastern Blue Ridge Mountains and Foothills. 1.2 WATERSHED CHARACTERIZATION AND SERVICE AREA Camp Grier lies within the headwaters of the upper Catawba River Basin (HUC: 03050101010010) and is proposed to serve the entire Catawba River Watershed (HUC: 03050101) in North Carolina, an area of 3,300 square miles that covers 11 counties. Per information found on the NC Department of Mitigation Services website, the population in the watershed is expected to nearly double in size from 1.8 million to 2.7 million residents between the years of 2006 and 2030. The NC Department of Environmental Quality (NC DEQ) 2007 Lower Catawba River Basin Restoration Priorities and 2009 Upper Catawba River Restoration Priorities documents, supplements to the original 2004 Catawba River Basin Watershed Restoration Plan, highlight the 40 current TLWs within the Catawba Basin. The TLWs are selected based on three criteria: Problems, Assets, and Opportunities. The Camp Grier Mitigation Bank project area appears to lie just outside a current TLW for the Upper Catawba Basin and will help meet Upper Catawba restoration goals outlined below and in the 2009 basin Restoration Priorities: · “Restoration of nutrient- and sediment-impaired waters (including tributary streams) of the Catawba River mainstem lakes (water supply reservoirs), including Lake James, Lake Rodhiss, Lake Hickory and Lookout Shoals Lake.” · “Protection of riparian buffers and aquatic habitat within the headwater reaches of asset-rich watersheds of the upper Catawba River basin, including the upper Linville River, North Fork Catawba River, Wilson Creek, Mulberry Creek, Johns River and Lower Little River.” · “Implementation of stormwater assessment and management efforts, including stormwater BMP projects, within urban and suburban subwatersheds in the Linville, Marion, Lenoir, Morganton, Hickory and Taylorsville areas.” · “Increased implementation of agricultural BMPs within heavily agricultural sub-watersheds of TLWs, including North and South Muddy Creeks, Silver Creek, lower Lower Creek, Lower Little River, Jumping Run Creek and Elk Shoal Creek.” Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O.

The purpose of the project is to compensate for losses of Waters of the State permitted by State and Federal regulatory agencies through the restoration, enhancement, creation and preservation of more than 20,000 linear feet of stream and approximately 0.5 acres of wetlands. The project will provide measurable water quality benefits to Padgett Branch and its tributaries, Jarrett Creek, Mill Creek and the Upper Catawba River by restoring impacted and unstable stream reaches and by reducing nutrient, sediment, and bacterial impacts conveyed to project area streams by stormwater, agriculture, and erosion. Ongoing stormwater impacts will be mitigated through implementation of a Stormwater Management Plan for the entire developed area of the parcel through stormwater and livestock Stormwater Control Measures (SCMs, formerly referred to as BMPs) and establishment and enhancement of wide and diverse native riparian buffers. The project will limit future impacts from camp related activities and create, improve and extend habitat from USDA National Forest land and unimpacted areas of the property and surrounding properties by increasing shade and supply of beneficial organic material (e.g. leaf pack) resulting in a reduction in water temperature and increase in dissolved oxygen levels in the streams. 1.4 FUTURE SITE DEVELOPMENT The Camp Grier property has suffered land and water quality impacts associated first with historic logging in the 1950’s, subsequently by agriculture, aquaculture, and lake building circa 1960. More recently impacts from increased camp development, related recreational activities and gravel and soil roads and trails are contributing most heavily to water quality impacts at the site. Roads and trails currently provide the conduit for sediment, nutrient, and biological water quality impacts. The demonstrable treat of future camp development is evident as new camp leadership has been successful in acquiring additional funding, developing new camp programs, and soliciting additional camp users of the property. New camp activities include an equestrian program, increased hiking trails, mountain biking trails and additional lake infrastructure and activities. More roads, trails and additional horse and livestock pasture are currently in the planning stages. Additionally, traditional mowing and vegetation management techniques used within riparian areas are contributing to nutrient, pollutant, sediment, and temperature impacts to Jarrett Creek and Padgett Branch within the project area and downstream. Without the establishment of the Camp Grier Mitigation Bank and its associated covenants and easement, that will permanently protect streams, impacts to wetlands and riparian buffers and water quality will continue and worsen. Additionally, future camp administrations may not have the foresight or interest to consider and pursue the mitigation banking and conservation option. Finally, if the camp were to ever become non-viable, as it nearly did several years ago, the owners of the property may consider sale of the property for development to fund church and mission related efforts. As planned, the CGMB will restore, enhance and preserve streams, wetlands and their buffers within the 109-acre area most heavily impacted by historic logging, lake creation, and past, present, and future camp and maintenance activities. Through the establishment of the CGMB, the site will likely continue to operate only as a wilderness camp with a new water and land quality educational component and awareness. Current impacts and new Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O.

The only currently foreseen use of the Camp Grier Parcel is as a wilderness camp and recreation area. 2.0 BASELINE CONDITIONS 2.1 COMMUNITY TYPES The CGMB lies in the “Blue Ridge Level III Ecoregion” of the US and the “Eastern Blue Ridge Foothills Level IV Ecoregion” according to the Ecoregions Map of North Carolina (Griffith, G.E., Omernik, J.M., Comstock, J.A., Schafale, M.P., McNab, W.H., Lenat, D.R., and MacPherson, T.F., 2002, Ecoregions of North Carolina, U.S. Environmental Protection Agency, Corvallis, OR, (map scale 1:1,500,000)). Natural Communities within the project area included altered Rich Cove and Acidic Cove Forrest (Schafale, M.P. and A.S. Weakley. 1990. CLASSIFICATION OF THE NATURAL COMMUNITIES OF NORTH CAROLINA THIRD APPROXIMATION. NC Natural Heritage Program, Raleigh, NC.) 2.2 VEGETATION Dominant vegetation within the riparian corridor includes, tulip poplar (Liriodendron tulipifera), black locust (Robinia pseudoacacia), various oak (Quercus var.), red maple (Acer rubrum), shellbark hickory (Carya laciniosa), rhododendron (Rhododendron var.), mountain alder (Alnus viridis), box elder (Acer negundo), Christmas fern (Polystichum acrostichoides) , New York fern (Thelypteris noveboracensis), jewel weed (Impatiens capensis), poison ivy (Toxadendron radicans) and stinging nettle (Urtica dioica) . Significantly large portions of the project area, where riparian buffers are to be restored and enhanced, are currently vegetated with maintained turf grasses. Some riparian areas, due to current vegetation management, are mostly bare soil. Exotic invasive plant species observed within the project area include but may not be limited to Japanese knot weed (Polygonum cuspidatum), multiflora rose (Rosa multiflora), Chinese grass (Boehmeria nivea) and Chinese privet (Ligustrum sinense). 2.3 SOIL CHARACTERIZATION The CGMB project area consists of slopes that range from nearly flat to steep, approximately 3% to nearly 100% slope. The project area is predominantly comprised of Chestnut-Ashe complex and Dillard loam soils. Chestnut-Ashe soils are classified as having slopes ranging from 50 to 95 percent, are well drained with a high runoff class, and a depth to restrictive feature greater than 80 inches. Dillard loam soils are classified as having slopes ranging from 1 to 5 percent, are moderately well drained, with a low runoff class, and a depth to restrictive feature greater than 80 inches. A USDA soil map for McDowell County and project area is included as Exhibit B. 2.4 HYDROLOGY AND HYDRAULIC CHARACTERISTICS The sub-basins and contributing watersheds for both Jarrett Creek and Padgett Branch extend beyond the CGMB project boundary and Camp Grier property boundary. Jarrett Creek, upstream of the project area to the Town of Old Fort water supply intake (which sits adjacent to the property boundary), is classified by NC Department of Environmental Quality (NC DEQ) as “C:HQW”. Jarrett Creek originates approximately 4.5 miles upstream of the Camp Grier property boundary entirely within USDA National Forest land at an elevation of approximately 4,000 feet on the southeast slope of Glass Rock Knob. Interestingly, Jarrett Creek within the Camp Grier property extending downstream to its confluence with Mill Creek has a water quality classification set by NC DEQ of “C”. Mill Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O. Drawer 870 ▪ Kitty Hawk, NC 27949 Telephone (252) 491-8147 ▪ Fax (252) 491-8146 ______________________________________ 5 Creek, downstream of Jarrett Creek, is classified as “C:Tr”. Jarrett Creek is a third order stream as it flows through Camp Grier Property and the project area. Padgett Branch above Camp Grier Lake is classified as a “B;Tr” while Padgett Branch below Camp Grier Lake is classified as “C:Tr” water. About half of the unnamed tributaries to Padgett Brach originate on Camp Grier property within the project area. Padgett Branch is a second order stream. Several of the goals of the CGMB project will be to: 1. Return the water quality classification of Jarrett Creek within the Camp Grier property and project boundary to a NC DWR Water Quality Classification of C:Tr or higher; 2. Restore Padgett Branch and its tributaries to B:Tr classification standards or higher. Reclassification of Padgett Branch to a standard representative of its current water quality may be beneficial to the CGMB project. The contributing watershed for Jarrett Creek is entirely undeveloped except for soil roads, infrastructure, and the inline impoundment related to the historic Town of Old Fort Water Supply (minimal), until the stream reaches the confluence of Padgett Branch and Camp Grier Road (located within 50 feet of one another). At this point warm, sediment, nutrient and bacterial laden stream water and stormwater enter Jarrett Creek which is causing visible and apparently measurable impacts to water quality. Downstream of the Padgett Branch/Jarrett Creek confluence the riparian buffer for Jarrett Creek narrows significantly and runoff from Camp Grier Road is impacting water quality through sediment, nutrient, and temperature inputs. As part of the CGMB project, Camp Grier has secured an option to purchase an approximately 100-feet wide, 4-acre strip of undeveloped land adjacent to Jarrett Creek in order to permanently protect Jarret Creek within the Camp Grier Boundary and project area. The average stream slope of Jarrett Creek was measured using existing topographic data to be approximately 9% and its contributing watershed above the project area is approximately 2,780 acres. The lower reach of Padgett Branch from it confluence with Jarrett Creek upstream to the Camp Grier Lake dam has been impacted historically by the building of Camp Grier Road and filling of the stream channel and associated floodplain with blasted rock debris fill. Large volumes of sediment are entering the Lower Padgett Branch through unmitigated stormwater flowing from Camp Grier Road. Sediment entry points were observed and noted at multiple distinct locations along the road/streambank. Unnatural upland sediment deposits are visible throughout the Lower Padgett Branch. Photos of unnatural sediment deposits as well as other portions of the project area are included as Exhibit C. The culvert that conveys Lower Padgett Branch beneath Camp Grier Road (approximately 100 feet below Camp Grier Lake Dam) is a barrier to aquatic passage. Padgett Branch does not appear to have a volume or depth of flow to support trout; however, should apparently support species of minnows and macro-invertebrates that support trout and other fauna. Interestingly, the Camp Grier Lake Dam appears as though it may impose less of an aquatic barrier than the referenced culvert due to its spillway design and the continual flow of water down the non-vertical dam face. This spillway structure appears that it may allow macro invertebrates to crawl up and over into Camp Grier Lake and continue upstream. The lake also provides an opportunity for restoration and/or enhancement through installation of a cool water release structure to Lower Padgett Branch.

Drawer 870 ▪ Kitty Hawk, NC 27949 Telephone (252) 491-8147 ▪ Fax (252) 491-8146 ______________________________________ 6 The average stream channel slope of Padgett branch from Camp Grier Lake Dam to its confluence with Jarrett Creek was measured using existing topographic data to be approximately 11%. The contributing watershed for all of Padgett Branch to the confluence of Jarrett Creek is approximately 460 acres. The main stem of Padgett Branch above Camp Grier Lake (Upper Padgett Branch) has a shallower slope than the lower reach downstream of the lake. Tributaries predominantly enter the upper reach from the north and from Camp Grier property. The slope of the main stem of the upper reach of Padgett Branch was measured to be approximately 3%-5%. Its tributaries, T1-T11 steepen significantly up valley. Much of the riparian buffer along the main stem of Padgett Branch is maintained using traditional non-environmentally sensitive mowing and vegetation management techniques. The main stem of Upper Padgett Branch and several of the downstream ends of its tributaries appear to have been historically relocated toward the edge of their natural valleys and appear to have been straightened and deepened. Four small impoundments have been observed and noted in Upper Padgett Branch and its tributaries, one along the main stem (reportedly historically used to fill the swimming pool), one in Tributary T1A (apparently to help regulate flow in trout ponds constructed in the riparian buffer), one in T2A (also associated with trout pisciculture) and a fourth in Tributary T2 for an unknown purpose (see Exhibit A). Finally, an apparent .01- acre wetland area at the upstream end of Tributary T2A has been historically impacted by excavation and water conveyance infrastructure. A United States Army Corps of Engineers (USACE) NC Wetland Assessment Methodology (NC WAM) form has been completed for this area and is included Exhibit D-Stream & Wetland Data Forms. 2.5 PRELIMINARY STREAM CLASSIFICATION Nearly all of the approximately 20,000 linear feet of stream within the CGMB project area have been observed on multiple occasions prior to preparation of this prospectus document. Photographic documentation of representative areas of streams are included as Exhibit C. USACE North Carolina Stream Assessment Methodology (NC SAM) forms have been completed for both Jarrett Creek and the main stem of Padgett Branch (Exhibit D). Preliminary cross-sections on the main stem of Padgett Branch were measured using non-survey grade techniques with conventional measuring tapes. Measurements were converted to cross-sections and measured dimensions were applied to the Key to Rosgen Classification of Natural Rivers. Cross-sections, current Rosgen Classifications, and proposed conditions are included as Exhibit E-Cross-Sections & Rosgen Classification. Jarrett Creek within the project reach has a lower slope (estimated to be 4%) than the reach above the Padgett Branch confluence. Jarrett Creek within the project area is preliminarily classified as a classic, minimally impaired “B4a-B5a” stream by the Rosgen Classification of Natural Rivers, however is suffering from the impacts discussed above. Lower Padgett Branch below Camp Crier Lake at Cross-Section 1 is preliminarily classified as an impaired “A5” stream. The main stem of Upper Padgett Branch above Camp Grier Lake at Cross-section 2 was preliminary assessed as an impaired “B6” stream with low sinuosity due to historic straightening and dredging. Further upstream above the swimming pool on Upper Padgett Branch at Cross-section 3, Padgett Brach was classified as an impaired G6 stream (Exhibit E). 3.0 CONCEPTUAL RESTORATION PLAN 3.1 OVERVIEW Mitigation within the project area will consist of Restoration (Levels 1-4), Enhancement Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O. Drawer 870 ▪ Kitty Hawk, NC 27949 Telephone (252) 491-8147 ▪ Fax (252) 491-8146 ______________________________________ 7 (Levels 1 & 2) and Preservation of streams and their buffers upstream of restored and enhanced areas. Riparian Buffer Restoration, and a holistic Stormwater Management Plan will contribute to the CGMB project and improvements in water quality and habitat. The Conceptual Mitigation Plan is attached as Exhibit A. 3.2 RESTORATION AND ENHANCEMENT Restoration of streams and wetlands within the project area is being conducted based on industry standard assessment techniques established by Rosgen/Wildland Hydrology, North Carolina State Stream Restoration Institute and United States Army Corps of Engineers. Assessment of channel dimension, pattern, and profile and natural channel design concepts are being used for streams within the project area. Streams will be designed to resemble and function as stable and natural streams and “reference” conditions. Wetland assessment and restoration is being conducted using the US Army Corps of Engineers three parameter approach and restored wetlands will be designed to possess wetland soils, a dominance of wetland plants, wetland hydrology and will mimic “reference” wetlands found in similar settings on the Camp Grier property and nearby. Wetlands within the project area have or will be delineated and flagged in the field before a formal Mitigation Plan is submitted for the CGMB project. Confirmation of jurisdictional boundaries for wetlands within the project area is requested before survey grade data is collected for the project by a NC Licensed Surveyor. It is assumed, based on observations made with in the project area that locations and lengths of streams are not accurately portrayed as “blue lines” on USGS maps of the area and other readily available sources of information. North Carolina Division of Water Resources, Stream Identification Forms have been filled out for many of the streams within the project area and the upstream jurisdictional extent of streams have been flagged in the field for these streams (Exhibit D). Confirmation of the jurisdictional boundary for streams within the project area is requested before survey grade data is collected for the project by a NC Licensed Surveyor. A large component of the restoration of streams that originate and flow through Camp Grier property will be a holistic Stormwater Management Plan that will address developed impervious surfaces within Camp Grier including gravel and soil roads and trails. Preliminary assessment of the site suggests that many of the impacts to streams within the project area and downstream are resulting from unmitigated stormwater inputs. Approximately 6,800 linear feet of stream is proposed to be restored within the CGMB project area. Stream restoration will include Priority 1, 2, 3, and 4 Options for restoring incised and impaired channels. Restoration and Enhancement of CGMB streams will be augmented by stormwater, sediment and erosion control, and agricultural Best Management Practices/Stormwater Control Measures (SCMs) that will significantly reduce: · Peak flows resulting from impervious surface runoff · Warm water temperature inputs · Sediment, nutrient, and biological inputs Riparian buffers within the project area will be restored, enhanced, and preserved to a minimum average width of 30 feet and much greater in many areas. Undisturbed riparian buffers and streams above the project area are proposed to be placed Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O.

The conceptual plan for the entire project area is visible in Exhibit A. JARRETT CREEK Jarrett Creek from the Camp Grier property line to the confluence with Padgett Branch is proposed to be restored by completing the following list of activities that are assumed to fall within the Enhancement Level I category. Specifically, enhancement of Jarrett Creek is proposed to include but may not be limited to: · Installation of an in-stream structure that will reduce hydraulic stress on the river- right streambank at the downstream bridge; · Removal of historic concrete and piping debris from the stream channel and streambanks near the upstream bridge; · Enhancement of the riparian buffer, including purchase of adjacent property so that the buffer can be expanded to greater than 150 feet width; · Installation of engineered SCMs along Camp Grier Road; · Adjustment to camber along Camp Grier Road to direct stormwater to SCMs. The conceptual plan for Jarrett Creek and surrounding project area is visible on Sheet 2 of Exhibit A. Jarrett Creek and Camp Grier Road are apparently located within a FEMA FIRM Zone. Proposed enhancement activities are not anticipated to require a FEMA No-rise Certification at this time in part because if this project is approved, the conservation easement for the project will encompass the entire FIRM zone and will preclude further encroachment and development. LOWER PADGETT BRANCH The lower reach of Padgett Branch (approximately 835 feet) is proposed to be restored by what is best described as Priority 3 Restoration in combination with stormwater and sediment and erosion control SCMs and riparian buffer enhancement (Sheet 3-Exhibit A). Lower Padgett Branch is a steep “A” stream type with natural bedrock and boulder grade control throughout (Exhibit E). A majority of Lower Padgett Branch is clogged with rock debris from road building activities associated with Camp Grier Road. The clogged channel appears to have increased hydraulic stress on the river-right side streambank which is causing erosion and bank failure (Exhibit C). The stream is further impaired by warm, unmitigated, sediment laden stormwater that originates from Camp Grier Road. The section of Camp Grier Road that produces stormwater flowing to and impacting Lower Padgett Branch will be modified to adjust camber, reduce its slope and direct stormwater to multiple, sequenced SCMs designed to mitigate stormwater for the design storm/precipitation event with an emphasis on infiltration. Rock debris is proposed to be relocated to failing and higher stress areas of streambanks and strategically placed to reduce near-bank hydraulic stress. Rock debris may also be carefully placed high on the river-left streambank (talus slope from road building) or be removed from the channel and project area altogether. The suspended culvert beneath Camp Grier Road is proposed to be addressed to improve aquatic passage. A cool water release structure is proposed to be installed in Camp Grier Lake. Please refer to Exhibit A for additional details about each restoration area. Exhibit E contains preliminary existing condition cross-sections of Lower Padgett Branch and Exhibit C contains photographs of this area. TRIBUTARIES T1, T1A, T1B, T1C & T1D Tributary T1 as it approaches Camp Grier Lake is proposed to be modified to include a forebay to trap sediment before it enters Camp Grier Lake. Proposed forebays may be Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O.

Fencing along the northeast side of the Horse Pasture (river-right side T1) and other development and infrastructure within a minimum 30-feet riparian area will be relocated outside the buffer to allow buffer enhancement and restoration. Priority 2 and 3 restoration options will be used in this area in combination with agricultural and stormwater SCMs. Historic trout farming infrastructure, construction and landscaping debris, and a small dam and sediment filled impoundment will be removed from Tributary T1A. Finally, a suspended culvert will be addressed at the upper road crossing over Tributary T1A to allow for improved aquatic passage. Above restoration areas, streams associated with Tributary T1 will be enhanced (Level 2) and preserved through the establishment of permanent trail crossings through stream buffers and over streams, installation of stormwater SCMs associated with the trails and historic soil roads, and recordation of the conservation easement and MBI for the CGMB project. Please refer to Sheets 8 and 9 in Exhibit A. UPPER PADGETT BRANCH AND TRIBUTARIES T2, T2A & T2B The riparian buffer is proposed to be restored and enhanced along Upper Padgett Branch these tributaries to a minimum width of 30 feet. The main stem of Upper Padgett Branch is proposed to be addressed using Priority 1 and 2 Restoration Options. Implementation of stormwater and Sediment and Erosion Control SCMs, realignment and camber/sloping of Camp Grier Road, and riparian buffer creation and enhancement will contribute to the restoration and presumably qualify as Enhancement Level 2 for areas upstream of restoration areas. A forebay is proposed just upstream of Camp Grier Lake in order to trap sediment before it enters the lake. Additionally, historic, sediment filled, impoundments and small dam structures will be removed from the main stem and tributaries of Upper Padgett Branch. Impoundment locations are shown on Sheets 4 and 5 of Exhibit A and in the photos within Exhibit C. Priority 2 and 4 Restoration Options are proposed along Tributaries T2, T2A and T2B (See Sheets 4 and 10-Exhibit A). Suspended culverts located beneath Camp Grier Road and access roads to the Maintenance Building and Caretakers House are proposed to be addressed by the restoration. Removal of a small dam structure and impoundment are proposed from Tributary T2. Stormwater SCMs are proposed for the Caretaker Cabin, Maintenance Building, Camp Grier Road and the other impervious areas that drain to the area. Wetland restoration is proposed at the upstream end of Tributary T2A in an area impacted by historic trout farming infrastructure. Above the restoration areas streams are proposed to be enhanced (Enhancement Level 2) and preserved through the establishment of permanent trail crossings, installation of stormwater SCMs, and recordation of the conservation easement and MBI for the project. UPPER PADGETT BRANCH AND TRIBUTARIES T3 & T3A Tributary T3 is proposed to be restored using a Priority 2 Restoration Option from its confluence with Padgett Branch upstream for approximately 300 feet to the access road for Main Camp (Sheets 5 and 12-Exhibit A). Two suspended culverts beneath Camp Grier Road and the Main Camp access road are proposed to be addressed as part of the restoration. Stormwater SCMs associated with the buildings, roads and infrastructure on the east side of Main Camp will contribute to the restoration. The reach of Tributary T3 extending upstream from the restoration area to a location just upstream of a cabin visible on Sheet 12 of Exhibit A is proposed to be enhanced (Level 1) through riparian buffer restoration and stormwater SCMs associated with impervious infrastructure. Above the cabin, Tributary T3 is proposed to be enhanced (Level 2) and Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O.

TRIBUTARIES T4, T4A, AND T5 Tributaries T4 and T5 are proposed to be restored using a Priority 2 Restoration Option in combination with riparian buffer establishment and stormwater SCMs. Restoration is proposed from the tributaries’ confluences with Padgett Branch upstream to Camp Grier Road. Enhancement Level 2 is proposed on Tributary T5 from Camp Grier Road to the jurisdictional stream boundary. Enhancement Level 2 is proposed on Tributary 4 from Camp Grier Road to the furthest upstream trail crossing. Preservation is proposed from this trail crossing to the jurisdictional boundary for the stream and is shown on Sheet 13 of the Camp Grier Conceptual Mitigation Plan. UPPER PADGETT BRANCH AND TRIBUTARIES T6, T7, AND T8 The upstream end of Padgett Branch appears to flow near to and possibly beyond the east property line with USDA forest service land. Until surveyed boundary information is available for this area, it is unclear whether the entire reach of Padgett Branch, or enough of its stream buffer exists on Camp Grier property for this area to be included in the project. Regardless, Enhancement Level 2 of Tributaries T6, T7, and T8, through the stormwater management associated with cabins, roads and trails that drain to the tributaries, are proposed as part of the CGMB project. Reaches of stream above enhancement areas are proposed to be preserved by the conservation easement and Mitigation Banking Instrument (MBI) for the project. TRIBUTARIES T9, T10, & T11 Tributaries T9, T10 and T11 that drain to Camp Grier Lake and Padgett Branch from the east from USDA National Forest land will be preserved by the conservation easement and Mitigation Banking Instrument for the project. 3.2.1 WETLAND RESTORATION AND CREATION Restoration of wetlands within the project area will include restoration of the wetland area associated with Tributary T2 described above. Creation of wetlands within the project area will consist of stormwater SCMs associated with impervious roads, buildings and infrastructure that drain to the Camp Grier Mitigation Bank project area, and the restoration of the existing Upper Padgett Branch. 4.0 PROPOSED MONITORING PLAN The Monitoring Plan for Camp Grier Mitigation Bank will be developed to demonstrate that the site is trending toward success and will meet the goals of the Mitigation Plan. The Monitoring Plan will adhere to the Monitoring and Performance Standards for Compensatory Mitigation in North Carolina document produced by the North Carolina Interagency Review Team-February 8, 2013 or more recent guidance specified by the Interagency Review Team (IRT) for this project as triggered by the submittal of this prospectus document in order to meet 33 CFR part 332 (Mitigation Rule). 4.1 GENERAL REQUIREMENTS Site monitoring will occur for a period of seven years. It is understood that if performance standards have not been met by year seven additional monitoring may be required. Monitoring reports will be completed annually for all seven years and will be submitted to USACE by April 1 of the year following the monitoring. Monitoring reports will be prepared and formatted per Regulatory Guidance Letter (RGL 08-03). Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O.

As-builts will include but may not be limited to: photo documentation of all cross-sections and structures, plan view diagrams, longitudinal profiles, vegetation information, and the location of all monitoring activities. As-builts will not be provided for Preservation-only portions of the project area. 4.2 Planted VEGETATION MONITORING Vegetation plots will be monitored for seven years with monitoring events on years 1-3, 5 and 7. Vegetation planting and replanting will be conducted between November 15 and March 15. Vegetation monitoring will be conducted between July 1 and leaf drop. Planted vegetation will be in the ground for no less than 180 days before the first year of monitoring on Year 1. Vegetation plots will be randomly located across the site to provide random sampling of all the vegetation community types reestablished at the site. Vegetation monitoring will follow the 16-step procedure outlined in the Monitoring and Performance Standards for Compensatory Mitigation in North Carolina requirements specified in Section V, A- Vegetation Planting and Monitoring Requirements and Section V B-Planted Vegetation Performance Standards 4.3 STREAM CHANNEL STABILITY AND HYDROLOGY MONITORING Stability and Hydrology Monitoring will be conducted per the Monitoring and Performance Standards for Compensatory Mitigation in North Carolina Section VI in order to show that proposed in-stream work has corrected channel bed and bank instability for areas of the site where instability is identified as a primary objective in the Mitigation Plan and for areas where instream work changes channel dimension below bankfull elevation. Channel stability will be monitored for seven years. Reference stakes marking surveyed stations and corresponding as-built survey and longitudinal profile will be installed in the buffer near the stream bank every 100 feet along the stream. Permanent, monumented cross-sections will be installed at an approximate frequency of one per 20 bankfull widths measured along the thalweg. Monitored cross-sections located in stream bends will include an array of bank pins per the referenced guidance. Lateral movement of the streambanks as indicated by pin exposure will be reported in all monitoring reports. Crest gauges will be installed to document bankfull events. At least one gauge will be installed on each tributary greater than 500 feet in length. One gauge will be installed for every 5,000 feet of length on each tributary. Stream Channel Stability and Stream Hydrology Performance Standards outlined in Section VI ,B of the referenced guidance will be followed. Jurisdictional stream determinations will be requested before the Mitigation Plan is complete. 4.3 STREAM WATER QUALITY AND MACROINVERTEBRATE MONITORING As with other stream monitoring described above water quality and macro-benthos monitoring will comply with Monitoring and Performance Standards for Compensatory Mitigation in North Carolina and specifically with Section VII of the referenced standards.

Drawer 870 ▪ Kitty Hawk, NC 27949 Telephone (252) 491-8147 ▪ Fax (252) 491-8146 ______________________________________ 12 Water quality sampling will be conducted prior to construction and twice a year throughout the monitoring period. Sampling will include measurements of pH, temperature, dissolved oxygen, and conductivity. Biological and nutrient monitoring will also be monitored in an effort to show a reduction in coliforms and nutrients. Each tributary longer than 500 feet will be sampled at two locations, one near the upstream and one near downstream end of the reach. Water quality sampling will be conducted during normal flow conditions 48 hours or longer after any precipitation event totaling one inch or greater as determined by nearby weather stations or on-site rain gauges. Macroinvertebrate sampling will be conducted prior to construction and once a year during monitoring years three, five, and seven. Sampling will be conducted on tributaries greater than 1000 feet in length. Sampling points will be located on riffles with the first point located on the lowest riffle of the tributary. A reference location will be sampled for comparison and will be located in an on-site preservation reach or upstream of the project area. All samples will be collected in accordance with the Qual 4 protocol described in Standard Operation Procedures for Collection and Analysis of Benthic Macroinvertebrates by a qualified professional. Water quality and macroinvertebrate sampling will be conducted during the same time of year and within the index period specified in the NC DWR Small Streams Biocriteria Development document (May 29, 2009). Samples will be identified to the lowest practical taxonomic level by a NC DWR certified laboratory for macroinvertebrates. 5.0 BANK OPERATION The subject property is currently owned by Camp Grier 501(c) (3) and the project area has not been encumbered by a conservation easement. A conservation easement does exist on Camp Grier Property to the west of the project area (Exhibit A-Sheet 1). The existing conservation easement in combination with the proposed CGMB conservation easement will protect all jurisdictional water on the 650 acre parcel with the exception of Camp Grier Lake. Camp Grier will serve as the legal entity and Bank Sponsor for the purposes of the CGMB project. Camp Grier, the Town of Old Fort, and the USDA Forest Service are the only entities that have any control of streams, wetlands, and infrastructure affecting the hydrology of the site. The CGMB project team, consists of licensed geologists, professional engineers, planners, and surveyors who have extensive experience in water resource and riparian restoration projects. In addition, the Sponsor employs staff that hold degrees in and have professional experience with business, finance, law ecology, forestry, and natural resource management. Together, the project team possess the necessary credentials to execute the proposed project such that it meets the goals that will be further outlined in the Mitigation Plan for the project. Some of the site evaluations (e.g. soil survey, stream and wetland delineations, and conceptual planning and design) have been completed for the site. However, a more detailed stream assessment, additional survey, design, and engineering work will be necessary for the development of the Mitigation Plan. A MBI will also be developed and submitted prior to completion of the Mitigation Plan and project construction. Upon acceptance of the final Mitigation Plan by the IRT, the Bank Sponsor will initiate proposed construction activities for the development of the CGMB site.

Prior to release of CGMB credits, the following requirements will be met: (1) approval of the final Mitigation Plan and execution of the MBI; (2) securing the bank site; and (3) establishment of appropriate financial assurances. Assuming the aforementioned ratios for stream and wetland: restoration, enhancement, and preservation are accepted and considering BCF adjustments, it is estimated that at least approximately 11,906 stream credits and 2 wetland credits will be generated through the establishment of the Camp Grier Mitigation Bank. It is assumed that the Bank Sponsor may choose to initiate construction of the project in two separate phases if market demand is deemed to be insufficient during the initial stages of development. A tentative Schedule for establishment of the bank site is outlined below. Upon execution of the MBI, a conservation easement deed for the site will conveyed to an appropriate public land trust organization such as Foothills Conservancy. The terms and conditions of the conservation easement will ensure the protection of the site in perpetuity. The ownership of the Bank will reside with the Sponsor until completion of the debiting of the Bank. The Sponsor is currently negotiating with several registered and/or certified land trust organizations to serve as the holder of the conservation easement. The holder of the conservation easement will be responsible for long-term protection and management of the site. The easement will prohibit any activities (e.g. timbering, farming, building, etc.) that would alter the environmental state of the Bank site. Conditions of the easement are proposed to not restrict passive recreational, educational, and/or research activities. The Bank Sponsor will be responsible for securing appropriate financial assurances in the form of construction, monitoring, and maintenance bonds to cover contingency measures in the event of Bank default or failure. Performance monitoring will be conducted for a 7-year period subsequent to project construction. Annual monitoring will evaluate the development of stream function and document site performance relative to established success criteria. In addition, monitoring activities will identify any site deficiencies that may warrant remedial action. Monitoring reports documenting site success and/or failure will be submitted to the IRT each year. Upon submittal of annual monitoring reports demonstrating the fulfillment of site success criteria, stream credits will be released according to an approved credit release schedule. The table below outlines proposed information on project timeline and credit release schedule. Camp Grier Mitigation Bank September 13, 2017 Prospectus P.O.
