Bane & h�w4a4geEBX-EM, LLC (EBX, an entity of Resource Environmental Solutions, LLC) i --acting as the Bank Sponsor, is pleased to provide this Bank Parcel Development Plan (BPDP) for the Maple View Riparian Buffer- an Nutrient Offset Mitigation Bank (Bank). This neer Bank is designed to provide nutrient offset mitigation credits for unavoidable impacts due to development within the Upper New Hope Arm of the B. Everett Jordan Lake watershed in the Cape Fear River BasinUnited States Ge,.i,.,.ica cufye, (USGS) H dr -al gig Unit Code (14UC) 03030002 This BPDP is in accordance with 15.4 NC -AC, 024.0.95 a��15A NCAC 02B.0240 and the Cape Fear Riparian Buffer & Nutrient Mitigation Banking Instrument (LIMBI) made and entered into by EBX-EM, LLC acting as the Bank Sponsor (Sponsor), and the North Carolina Department of Environmental Quality (NCDEQ, on _October 9, 2009 and modified on February 17, 2014. Supporting figures can be found in Appendix A. 1.1 Parcel Location The Maple View Parcel is located in Orange County in Hillsborough, NC (Figure 1). Within the Parcel, a section of Morgan Creek and two unnamed tributaries traverse the site and exhibit diminished habitat value as a result of past and on-going agricultural activities and impervious watershed conditions. The Parcel is located within the Upper New Hope Arm of the B. Everett Jordan Lake watershed USGS 14 - digit HUC 03030002060070 and North Carolina Division of Water Resources (NC DWR) Sub -basin Number 03-06-06. The site is located near the intersection of Green Rise Road and Dairyland Road (SR 1177). The site is on the south side of Dairyland Road with the main drainage feature flowing west to east. The coordinates of the site are 35.973056°N and -79.147778°W. 1.2 Parcel Overview The conservation easement on the Maple View T�4ie M Parceltotals approximately 7.63 acres and includes two unnamed tributaries., and-sStormwater runoff from adjacent land tflows directly to Morgan Creek. The Parcel is located in an area dominated by agriculture, livestock, and residential land use. There is a dairy operation on the north side of Dairyland Roadbut. A majority of the Parcel is utilized for row -crop production. Land use in the project area is hay field, row crops, and existing riparian forest. No livestock are on the Bank Parcel, thereforeT4yn:e is livestock access is not a concernto the project area. The Maple View Nutrient Offset Mitigation Bank is proposed to provide water quality benefits through elimination of nutrient intensive agricultural practices and re -forestation of riparian areas that extend out to 200 feet from the stream channels. The riparian restoration activities within the Parcel will result in improved water quality within the downstream watershed. Unnamed Tributary "A" is a perennial channel which flows in an easterly direction along the southern project boundary. Unnamed Tributary `B" is a perennial channel which flows in a southerly direction to its confluence with unnamed tributary "A". Unnamed Tributary "C" is a perennial channel flowing in a southerly direction to its confluence with UT- A.

Maple View Parcel Development Plan Nutrient Offset Site 2 April 2016 The Maple View Parcel is being proposed to provide off-site mitigation for development (both existing and proposed) requiring nutrient offset credits. The nutrient offset credit sm4igation-proposed in -on this Bank is being submitted under the terms and conditions of the maple Vie., Mitigation tion Banking Tnstr—u ACape Fear UMBI modified and signed on February 2, 2014 between EBX-EM, LLC and the Department of Environmental Quality. 2 PROJECT AREA — EXISTING CONDITIONS 2.1 Physiography The Parcel is in the Piedmont Physiographic Province of North Carolina, specifically within the Carolina Slate Belt ecoregion. A review of the Ecoregions of North Carolina and South Carolina (Griffith et al., 2002) shows the geology in the area of the property is comprised of "mineral -rich metavolcanic and metasedimentary rocks with slately cleavage," which is finer grained and less metamorphosed than other eco -regions within the Piedmont. It is also common for streams to dry up, along with low yielding wells. Elevations range from 154 to 172 feet above mean sea level (NAD 27) based upon USGS mapping (Figure 2). The Site's tributaries form the headwaters of Morgan Creek. Within the proposed mitigation area, the channels drain surface water and groundwater from the surrounding agricultural areas. 2.2 Soils Based on Orange County soil survey mapping (USDA 1977), the Parcel contains three soil series: Chewacla loam, Goldston slaty silt loam, and Herndon silt loam. (Figure 5). The soil series found on the site are described below and summarized in Table 1. Table 1. Parcel Mapped Soil Series Map Unit Map Unit Name Drainage Class Hydric Status Hydrologic Soil Group Symbol Ch Chewacla loam Somewhat poorly Hydric B/D drained Goldston slay silt GIF loam, 15 to 45% Well drained Not Hydric D slopes HrB Herndon silt loam, Well drained Not Hydric B 2 to 6/o slopes HrC Herndon silt loam, Well drained Not Hydric B 6 to 10% slopes Chewacla loam. This is a somewhat poorly drained soil found on floodplains of streams. It has moderate permeability and negligible to low runoff. This soil typically floods frequently for brief periods. The seasonal high water table ranges from 6 to 24 inches below the surface. It has sometime has clayey subsoil. Uses are for pasture, cropland, and forest. This soil is considered prime farmland when drained. This soil is considered to have hydric inclusions by the NRCS. Maple View Parcel Development Plan Nutrient Offset Site 3 April 2016 Goldston slay silt loam. This well drained soil occurs on side slopes adjacent to major drainage ways, with mapped areas typically being narrow bands. The underlying material, extending to a depth of 24 inches, is mottled pale brown saprolite that crushes to silt loam. The permeability of is moderately rapid, and the potential for crop production is low. The soil has medium potential for broad leaved and needle leaved trees. Herndon silt loam. The Herndon series consists of very deep well drained moderately permeable soils that formed in material mostly weatehered from fine grained metavolcanic rock of the Carolina Slate Belt. It occurs on broad ridges and (2 to 6 percent slopes) narrow side slopes (6 to 10 percent slopes) on uplands. Most of this soil is used as cropland, but it has high potential for broad leaved and needle leaved trees. 2.3 Vegetation Vegetative communities within the Bank Parcel can be grouped into two distinct vegetative communities. These two vegetative communities can be generally characterized as a Piedmont Alluvial Forest, according to the North Carolina Natural Heritage Program (NIP) classification system (Schafale and Weakley, 1990) classification system and pasturelandagriculture. Dawe lan Agricultural areas are subject to periodic mowing and crop production (i.e. hay and orn productionb.

As a result, there are non_- - - Commented [MK4]: t don't see evidence on Google Earth or on native invasive species such as multiflora rose and Chinese privet located within the fringe of these the ground that this Parcel was in cattle in the past. communities. Dominant species noted within these communities include various oak species (Quercus sp.), river birch (Betula nigra), American elm (Ulmus Americana), tulip poplar (Liriodendron tulipifera), various hickory species (Carya spp.), red mapl (Acer ruhrum), and sweet gum (Liquidamhar styraciflua). 2.4 Threatened and Endangered Species Plants and animals with a federal classification of endangered (E) or threatened (T) are protected under provisions of Sections 7 and 9 of the Endangered Species Act of 1973, as amended. The US Fish and Wildlife Service database (updated 22 September 2010) lists three endangered species for Orange County, North Carolina: dwarf wedgemussel (Alasmidonta heterodon), Michaux's sumac (Rhus mixhauxii), and smooth coneflower (Echinacea laevigata) (Table 2). The Bald eagle (Haliaeetus leucocephalus) is protected under the Bald and Golden Eagle Protection Act (BGPA) and prohibits take of bald and golden eagles. No protected species or potential habitat for protected species was observed during preliminary site evaluations. In addition to the USFWS database, the NC Natural Heritage Program (NHP) GIS database was consulted to determine whether previously cataloged occurrences of protected species were mapped within one mile of the project site. Results from NHP indicate that there are no known occurrences of state threatened or endangered species within a one -mile radius of the project area. Based on initial site investigations, no impacts to state protected species are anticipated as a result of the proposed project.

EBX has evaluated the Parcel's existing and future conditions of cultural resources to determine potential project impacts. The evaluation focused primarily on the presence of hazardous materials, utilities and restrictive easements, rare/threatened/endangered species or critical habitats, cultural resources, and the potential for hydrologic trespass. A review of the North Carolina State Historic Preservation Office (SHPO) GIS Web Service database did not reveal any listed or potentially eligible historic or archeological resources in the proposed project area. No architectural structures or archeological artifacts have been observed or noted during surveys of the site for restoration purposes. 2.6 FEMA Floodplain/Floodway Mapping Hydrologic trespass is a not a concern for this project. The Maple View Site is not located within a FEMA 100 year floodway (Figure 6). While designing the Maple View project, appropriate measures were taken to eliminate hydrologic trespass of the adjacent agricultural fields and animal operations. The adjacent land use will not be affected by the proposed design, and the property owners have been notified of any potential impacts from hydrologic trespass within existing ditches. No detrimental _ - - Commented [MKS]: what does this mean? Plugging, filling? It impacts are expected beyond the easement limits. didn't appear that any ditches were being proposed for restoration. 3 RESTORATION PLAN 3.1 Nutrient Offset Restoration Activities The primary goals associated with the nutrient offset restoration plan include improving water quality, enhancing flood attenuation, and restoring wildlife habitat through the creation/restoration-acrd enhancement of a -forested riparian buffer areas adjacent to stream channels within the Parcel. The restoration of natural plant communities within the Parcel will not only provide stabilization and improve water quality within the easement limits, but also provide ecological benefits to the entire watershed. The majority of the site has been previously maintained as a cleared agricultural field for hay and corn production. As such, these areas are relatively clear and require little site preparation other than select herbicide treatment and soil preparation (i.e. ripped and scarified). The bu€fv�riparian areas will be planted with native bare root tree seedlings on an 8 by 8 foot spacing to achieve an initial density of 680 trees per acre. The buffered channels will provide water quality and habitat functions within the sensitive Maple View Parcel Development Plan Nutrient Offset Site 5 April 2016 Jordan Lake watershed. Some areas adjacent to the forested areas may require maintenance due to the rapid regeneration of some species. Rapidly regenerating species and invasive species may develop greater individual species density and create a less diverse mix. Minimal maintenance is anticipated due to the past cultivation history. ^�r-ice Riparian restoration will begin at the outer limits of the existing tree lines and extend out to 200 feet from the top of bank from reaches A, B and C (Figure 8). Approximately 3 acres of mature forest will be protected within the conservation easement, but no buffer or nutrient offset credits will be generated. 3.2 Planting Plan Revegetation of the site will include planting bare root trees and controlling invasive species growth. Piedmont Alluvial Forest will be the target community type and will be used for all areas within the project. The community is defined by Schafale and Weakely (1990). The initial planting of bare root trees will occur in late Fall 2016 Tree species specified for planting on the Maple View Site are shown in Table 3. Table 3.

Boundaries may be identified by marker, bollard, post, tree -blazing, or other means as allowed by site conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as needed basis. No livestock is currently accessing the site and no fencing is proposed. The easement boundary will be checked annually as part of monitoring activities and reported to NC DWR. 4 _MONITORING AND MAINTENANCE PLAN 4.1 Monitoring Protocol and Success Criteria The Sponsor shall submit to NCDWR an annual monitoring fepoft for each phase, no later than December 31 of each year for five consecutive years. Reports will document the success of the vegetation and any maintenance, supplemental planting of encfoachment within the easement areas. Riparian buffer vegetation Maple View Parcel Development Plan Nutrient Offset Site 6 April 2016 Commented [MK6]: Planted?? monitoring will be based on the CVS-EEP Protocol for Recording Vegetation Level 1-2 Plot Sampling Only Version 4.0. Annual vegetation monitoring will occur each year during the fall season with the first year occurring at least 5 months from initial planting. Permanent Vv_egetation monitoring plots will be a minimum of 100 mz in size, and cover at least two percent of the planted area throughout the 5 years of monitoring. A fefefence photo will be taken from one comer of each plot. All planted stems in the plots will be mofked with flagging tape and fecofded. rThe following data will be recorded for alllap nted trees in the , , Commented [MK7]: Approximately how many Plots? plots: species, height, planting date (or volunteer), and grid location. The measures of vegetative success for the Parcel will be the survival of at least 320 planted trees per acre at the end of Year 5. Natural recruits will not count towards annual success criteria; however, they may be taken into account during review by the NC DWR._ Invasive and noxious species will be monitored and controlled so that none become dominant or alter the desired community structure of the site. Initial plant maintenance may include a one- time mowing in any of the planted riparian areas that are within the Jordan Lake Riparian Buffer as defined in 15A NCAC 02B .0267Zone A and mowing as needed within planted areas outside of the riparian buffer in Zones B and /�a C to remove undesirable species in the restoration areas. If necessary, EBX will develop a species-specific control plan. Monitoring bonds shall be fenewed with confirmation of fenewal pfovided to DWR with each annual monitoring fepoft. DWR fesefves the fight to altef the cfedit feleose schedule if monitoring fepofts afe submitted without pfoof of bond fenewals. 4.2 Adaptive Management Plan In the event that the site, or a specific component of the site, fails to achieve the defined success criteria, EBX will develop necessary adaptive management plans and/or implement appropriate remedial actions for the site in coordination with the NC DWR. Remedial actions will be designed to achieve the success criteria specified previously, and will include identification of the causes of failure, remedial design approach, work schedule, and monitoring criteria that will take into account physical and climatic conditions. 4.3 Long Term Management Plan EBX-EM, LLC, acting as the Bank Sponsor, will -has recorded e^�'t^h a Conservation Easement on the Bank Parcel with the Orange County Register of Deeds office.
