The project is located within the NC Division of Mitigation Services (DMS) targeted watershed for the Neuse River Basin Hydrologic Unit (HU) 03020201030030 and NC Division of Water Resources (DWR) Subbasin 03-04-01. The Site was selected by DMS to provide stream mitigation units (SMUs) and buffer credits in the Neuse River Basin 03020201 (Neuse 01). The project involves the restoration of 1,814 existing linear feet of incised and straightened streams from two unnamed tributaries to Buckwater Creek. These streams have been given names by Wildlands to facilitate labeling and communication in this mitigation plan and for the life of the project (Figure 2). The mainstem is hereafter referred to as Martin Dairy and its tributary as UT1. Restoration of these reaches will provide 2,135 SMUs. The project will also restore 10.14 acres of riparian buffer on- site, which will provide 394,742 buffer credits. The Site will be protected by an 11.155 -acre conservation easement. The Site Protection Instrument detailing the easement is located in Appendix 1. Table 1: Project Attribute Table Part 1— Martin Dairy Mitigation Site Project Information Project Name Martin Dairy Mitigation Site County Orange Project Area (acres) 11.155 Project Coordinates (latitude and longitude) 36° 7'25.76"N 79'0'14.26"W Planted Acreage (acres of woody stems planted) 10.14 2.0 Watershed Approach and Site Selection The 2009 Neuse River Basinwide Water Quality Plan lists major stressors in Subbasin 03-04-01 to be total suspended solids (TSS), nutrients, and chlorophyll a. The 2010 Neuse River Basin Restoration Priorities (RBRP) highlights the importance of riparian buffers for stream restoration projects. Riparian buffers retain and remove nutrients and suspended sediments. Of the 123 miles of streams in the Neuse 01 CU, 23% do not have adequate riparian buffers. The RBRP states that "priority [restoration] projects should increase or improve buffers." Another goal of the RBRP for the Neuse 01 HU is to support the Falls Lake watershed plan. Falls Lake is the receiving water supply water body downstream of the Site and is classified as water supply waters (WS -IV) and nutrient sensitive waters (NSW). The RBRP also states that a goal for the Neuse 01 CU is to, "...promote nutrient and sediment reduction in agricultural areas by restoring and preserving wetlands, streams, and riparian buffers." The Martin Dairy Mitigation Site was selected because of its location within the targeted watershed and its potential to address the goals of the RBRP through stream restoration and buffer restoration. Restoration of streams on the Site will directly and indirectly address stressors identified in the RBRP by creating stable stream banks, restoring meandering pattern, and restoring a forested buffer. The project will slow surface runoff, increase retention times, provide shade to streams, and reconnect the streams to their historic floodplains and riparian wetlands, which should reduce sediment and nutrient loads which contribute to the production of chlorophyll a in downstream waters. In addition, restoration will provide and improve instream and terrestrial (riparian) habitats while improving stream stability and overall hydrology. Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 1 March 2017 3.0 Baseline and Existing Conditions The Site watershed (Table 2 and Figure 3) is located in a northwestern HU of the Neuse 01 CU. It is situated in the rural countryside in Orange County near Hillsborough, NC, upstream of the intense growth and development pressure associated with the Raleigh-Durham metropolitan area. The following sections describe the existing conditions of the watershed and watershed processes, including disturbance and response. Table 2: Project Attribute Table Part 2 — Martin Dairy Mitigation Site Project Watershed Summary Information Physiographic Province Piedmont Ecoregion Slate Belt River Basin Neuse River USGS HUC (8 digit, 14 digit) 03020201, 03020201030030 NCDWR Sub -basin 03-04-01 Project Drainage Area (acres) 526 Project Drainage Area Percentage of Impervious Area 0.40% CGIA Land Use Classification 59.0% forested, 40.6% cultivated, 0.4% impervious 3.1 Landscape Characteristics 3.1.1 Physiography and Topography The Site is located in the Piedmont Physiographic Province of North Carolina. The Piedmont Province is characterized by gently rolling, well rounded hills with long low ridges and elevations ranging from 300- 1500 feet above sea level. The Site topography and relief are typical for the region, as illustrated in Figure 4. Martin Dairy has a gentle (0.65%) alluvial valley that transitions from moderately confined at 60 feet wide at the upstream end of the Site to unconfined at over 200 feet wide at the downstream end of the Site. UT1 transitions from a steep (1.81%) confined valley (<50 feet wide) at the upstream project limit to a moderately confined valley (>100 feet wide) as it approaches its confluence with Martin Dairy. Due to the valley shape in conjunction with dredge spoil present along the right bank of Martin Dairy (from when the channel was straightened and deepened), a swath of wetlands developed at the toe of the right valley slope. The wetland position and extents within the landscape has been consistent according to available historic aerial topography dating back to 1938. These wetlands are in danger of draining should Martin Dairy continue to incise. 3.1.2 Geology and Soils The Site is located in a portion of the Piedmont known as the Carolina Slate Belt (NCGS, 1985). The rocks in this region are primarily volcanic and sedimentary rocks that underwent low-grade metamorphism giving them a slaty cleavage. Coarse-grained intrusive granites comprise the rest of the Slate Belt rocks (Rogers, 2006). The geology of this area has important effects on Site hydrology, hydraulics, geomorphology, and sediment transport. Streams in the Carolina Slate Belt tend to go dry during late summer and early fall as a result of geologic, topographic, and climatic factors. A study by Guise and Mason (1993) states that the, "Carolina slate belt has among the lowest potential for sustaining baseflow in streams" throughout the year as compared to other regions of North Carolina. Median low flows in the Carolina Slate Belt, defined by the study as the 7Q10 (the annual minimum 7 -day consecutive low flow), can be as low as 0.005 ft3/s/mi2 of drainage area (Guise and Mason, 1993). If streambank vegetation is not well established it can die back in late summer when flows are low, leaving banks exposed to erosive storm flows. This process appears to happen during the summer months and Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 2 March 2017 periods of drought along Martin Dairy and UT1. Existing streambank vegetation is dominated by pasture grasses that die back for a portion of the year. The exposed banks lack the roughness necessary to reduce channel velocities. High channel velocities and shear stresses increase bed scour during these times. This has resulted in the process of channel incision followed by widening. There is evidence of bank sloughing along the length of Martin Dairy, forming temporary benches that eventually mobilize through the system. These erosional processes deliver sediment and its adsorbed nutrients downstream. It is likely that these processes are occurring on the livestock operation east of Schley Road, which drains into UT1, and on other unbuffered streams within the watershed. There is currently no evidence that aggradation is occurring in the system. The Martin Dairy floodplain is dominated by Chewacla loams (Figure 5). While this soil frequently floods and is poorly drained, aiding in the maintenance of wetlands, the loamy soil is greater than 80 inches deep. This depth to bedrock provides no natural grade control within the streambeds. Without intervention, channel incision would likely continue to degrade the Site streams until the channels reach the underlying bedrock. It is Wildlands' experience that small streams in the Slate Belt are low bedload sediment supply systems. These streams commonly have small gravel and sand bed material that is derived from highly weathered parent material. Largely forested watersheds with low rolling topography will often result in low sediment supply. Without naturally high bedload supply to drive morphologic change, these streams are relatively slow to adjust without manipulation or watershed disturbance. 3.2 Land Use/Land Cover Land use and land cover were investigated throughout the watershed using historical aerials of the Site and adjacent parcels from 1938-2016 and a watershed reconnaissance survey. The watershed is 60% forested. The most common historical and current land uses in the watershed are silviculture and agriculture. While 40% of the watershed has been previously cleared, recent logging events in the watershed have been infrequent and limited in disturbed acreage. The largest recent event noted on historical aerials was of 3.6 acres cleared between 2009 and 2010. This constitutes less than one percent of the watershed. The Site itself has been used for livestock grazing or maintained as managed herbaceous cover since at least before 1938. The limits of riparian buffers and agricultural land on Site have remained consistent over that time. In recent history, the Site was an active dairy farm. The livestock were removed and the Site transitioned to hay production over three years ago. There are no signs of impending land use changes or development pressure that would impact the project in the Martin Dairy watershed. This consistency in land use within the project watershed over the past 78 years indicates that watershed processes affecting hydrology, sediment supply, and nutrient and pollutant delivery have not varied widely over time. With a lack of developmental pressure, watershed processes and stressors from outside the project limits are likely to remain consistent throughout the implementation, monitoring, and closeout of this project. These stressors and processes are discussed further in Section 4, below. Aerial photographs from 1938 -present depict the Site in a managed open field condition with the stream maintaining its location. The lack of sinuosity on Martin Dairy, and the presence of dredge spoil material along the top of banks suggests that the channels were straightened for agricultural purposes prior to 1938. Ditches, located along the right floodplain of Martin Dairy, partially drain the riparian wetlands. Both Martin Dairy and UT1 enter the project via culverts. The channel has incised over a foot downstream of the culverts, creating a barrier for aquatic organism passage to upstream reaches within the watershed. Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 3 March 2017 3.3 Existing Vegetation Streamside vegetation consists primarily of herbaceous plants and grasses such as fescue (Fescue spp.) smartweed (Polygonum spp.), Johnson grass (Sorghum halepense), and purple lovegrass (Eragrostis eragrostis) with some broom sedge (Carex scoparia), golden rod (Solidago spp.), ironweed (Vernonia altissima), and cardinal flower (Lobelia cardinalis). There are also some young sweet gums (Liquidambar styraciflua), red maple (Acer rubrum), green ash (Fraxinus pennsylvanica), and small black willows (Salix nigra) present near the top of the stream bank. Portions of UT1 are choked with cattail (Typha latifolia). Invasive species include multiflora rose (Rosa multiflora) and Chinese privet (Lagustrum sinense) with Johnson grass and cattail considered nuisance species. The watershed has likely been logged multiple times since pre -disturbance although recent logging (post 1938) has been limited. Most tree species located in surrounding riparian areas are mid -successional or planted pine. The species in these areas are not necessarily indicative of what would have been on-site pre -disturbance. 3.4 Project Resources On May 19, 2016, Wildlands investigated on-site jurisdictional waters of the U.S. within the proposed project easement area. Jurisdictional areas were delineated using the US Army Corps of Engineers (USACE) Routine On -Site Determination Method. This method is defined by the 1987 Corps of Engineers Wetlands Delineation Manual and the subsequent Eastern Mountain and Piedmont Regional Supplement. All jurisdictional waters of the U.S. were located by sub -meter GPS. Wetland determination forms representative of on-site jurisdictional areas as well as non -jurisdictional upland areas are included in Appendix 2. The wetland delineation was confirmed on Site by USACE staff on July 28, 2016 and the jurisdictional determination was approved on December 9, 2016. There are four jurisdictional wetland features located on-site (A -D). These wetland features are classified as seeps using the evaluator's best professional judgement. The wetlands occur in the side slopes and the floodplains that drain to Martin Dairy. These features exhibit a high water table, pockets of shallow inundation, saturation within the upper 12 inches of the soil profile, and a low chroma matrix. Common hydrophytic vegetation includes wild mint (Mentha arvensis), longhair sedge (Carex comosa), and common rush (Juncus effuses). Much of these areas are impacted from farming practices including hay production. The Site contains two perennial streams: Martin Dairy and UT1. It also contains a short potion of an ephemeral channel (E1) at the downstream end of the Site. This feature was confirmed as ephemeral by staff from the DWR on April 5, 2016. NC DWR Stream Identification Forms (Version 4.11) are in Appendix 3 along with a confirmation letter from DWR regarding the ephemeral reach. US Army Corps of Engineers (USACE) forms are in Appendix 2. Stream features are described in more detail in Section 5. Table 3 provides a summary of water resources within the project limits. Existing conditions are also illustrated in Figure 6. E1 exhibits little erosion and appears to be relatively stable. The downstream end of the reach holds water for part of the year and it has been delineated as a wetland (Wetland A). Martin Dairy's stream type classification is most nearly described as varying between an incised and straightened E4 and C4 stream type, as the top width widens and narrows along the length of the stream. UT1 is best classified as an incised and straightened E4. The dominant bed material in both reaches is a small gravel. Cross- sections 1-4 are located along Martin Dairy and cross-sections 5 and 6 are on UT1 (Figure 6). Cross- section and reach -wide pebble count results are located in Appendix 5.

The Rosgen classification system (Rosgen, 1994) is for natural streams. These channels have been heavily manipulated by livestock and man and therefore may not fit the classification category as described by this system. Results of the classification are provided as a basis for discussion of existing channel form. 2. The Ephemeral reach E1 will not be restored for mitigation credit; however, it will be re -aligned as needed to tie in to the new alignment for UT1. 3. Wetland areas are not proposed for restoration or enhancement credit. 4.0 Watershed and Channel Disturbance and Response As discussed above in Section 3.2, there has been very little change in the watersheds of Martin Dairy and UT1 for several decades. Some clearing of forest has occurred but these minor disturbances are the not the main driver of the degradation of the Site. The primary cause of degradation on the Site was the original clearing of the Site and channelization of Martin Dairy and UT1, which occurred prior to 1938 (the date of the earliest available aerial photo). The channelization involved straightening and deepening of the stream (as indicated by the amount of dredge spoil in the floodplain). This manipulation led to increased shear stresses which caused incision, especially in Martin Dairy where the upstream culvert is now one foot above the channel bed. UT 1 is less incised because its down -cutting was arrested by the base level of the receiving stream. Over time, the incision reduced the overall channel slope in Martin Dairy which resulted in decreases in stream power. As incision slowed the channels began to widen through mass wasting and livestock trampling. Though livestock are no longer Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 5 March 2017 grazed on the Site, signs of on-going bank sloughing are apparent in both channels. Although less incision occurred in UT1 after channelization, both streams are overly deep, widening, sloughing, and devoid of riparian vegetation (other than pasture grass) due to agricultural uses of the Site. 5.0 Functional Uplift Potential The potential for functional uplift is described in this section according to the Stream Functions Pyramid (Harman, 2012). The Stream Functions Pyramid describes a hierarchy of five stream functions, each of which supports the functions above it on the pyramid (and sometimes reinforces those below it). The five functions in order from bottom to top are hydrology, hydraulics, geomorphology, physicochemical, and biology. 5.1 Hydrology The major watershed disturbance, prior to 1938, has been deforestation and conversion of 40% of the watershed to agricultural land uses. These alterations in land cover typically result in reductions in rainfall interception and evapotranspiration which lead to increases in runoff and water yield (Dunne and Leopold, 1978). A primary result of these changes is an increase in both peak flows and base flows, though the magnitude of this effect is likely small in watersheds of this size. Initial increases in water yield usually change over time as vegetation regrows and crops are planted. There are no stream gauges within this watershed and, thus, no way to know the degree to which clearing of 40% of the land affected this particular watershed other than to say that water yields have almost certainly increased. However, these changes primarily occurred several decades ago (prior to available aerial photography) and additional clearing in the watershed has been limited. The watershed has adjusted to its hydrologic regime and is stable now. Population growth in this rural area is essentially non-existent. Therefore, future alteration to the land cover and associated effects on hydrology are not expected in the foreseeable future. No measurements of existing conditions in hydrology have been made to date for this project. However, due to the stability of the watershed the Site hydrology is assumed to be functioning (Table 4). A stream restoration project performed at a specific Site does not often result in uplift to hydrology (Harman, 2012). Even though trees will be planted within the conservation easement, this will not result in improvements to the rainfall -runoff relationship at the watershed scale. Therefore, there is no opportunity to improve the hydrology function. However, it is currently rated as functioning (Table 4). 5.2 Hydraulics The streams on the Site are channelized and incised and not connected to their floodplains. This has resulted in reduced hydraulic functioning of the channels. The bank height ratios on Martin Dairy range from 1.4 (functioning -at -risk) to 1.9 (not functioning). On UTI, the bank height ratio is 2.1 (not functioning). However, the entrenchment ratios on Martin Dairy range from 14.2 to 14.3 (functioning) and on UT1 the entrenchment ratio is 2.2 (functioning). Estimated bankfull flow velocities for Martin Dairy range from 3.8 to S feet per second (functioning) and on UT1 the estimated bankfull velocity is 4.7 (functioning). Because the streams are severely incised but flow dynamics are functional, the overall rating for hydraulics on the Site is functioning -at -risk (Table 4). The channel will be reconstructed and will be connected to its floodplain so that stream flows above bankfull stage will flood the floodplain. The bank height ratios for both streams on the Site will be 1.0 (functioning). Bankfull flow velocities and shear stress will be maintained at functioning levels and groundwater exchange and adjacent wetland hydrology will be improved as a result of the increased frequency of floodplain inundation. Hydraulics will transition from functioning -at -risk to functioning (Table 4). Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 6 March 2017 Table 4: Summary of Stream Functions — Martin Dairy Mitigation Site Resource Martin Dairy - R1 Martin Dairy - R2 UT1 Functional Category Existing Proposed Existing Proposed Existing Proposed Hydrology F F F F F F Hydraulics FAR F FAR F FAR F Geomorphology NF F NF F NF F Physiochemical NR NR NR NR NR NR Biology NR NR NR NR NR NR Overall FAR F FAR F FAR F 5.3 Channel Geomorphology The past channelization, incision, and on-going sloughing and widening described in Section 4 places the streams on the Site at Stage IV of the Simon Channel Evolution Model which is classified as not functioning. Currently, Martin Dairy exhibits scour along 31% of the reach. Martin Dairy is moderately incised over 75% of its length. Over half of the length of UTI is incised (54% of the stream length), with bank height ratios averaging 2.1. Nearly half of the streambanks exhibit signs of active scouring (48%). The channel bottom of this straightened tributary is choked with cattail and common rush. The bedform is inconsistent on Martin Dairy and pool to pool spacing ratios (1.6 - 10.6) vary widely over the project length (not functioning). UT1 has more consistent bedform, however the pool to pool spacing ratio (average 6.5) indicates the bedform is functioning -at -risk. There is little to no large woody debris (LWD) in either of the streams on-site (not functioning). Bank migration and lateral stability were not measured for this project due to its straightened status. Overall, the existing geomorphology function on the Site is very poor and is classified as not functioning (Table 4). There is an opportunity to improve the geomorphology function on the site. The incision and bank erosion will be corrected. Bedform will be diversified and spaced with appropriate design ratios. LWD will be added to the system through construction of instream structures and bank revetments and a riparian buffer will be planted. The geomorphology function will be restored to functioning (Table 4). 5.4 Physicohemical No water quality sampling has been conducted on the Martin Dairy Site and there are no water quality monitoring stations within the watershed. The 2009 Neuse River Basinwide Water Quality Plan lists major stressors in Subbasin 03-04-01 to be TSS, nutrients, and chlorophyll a. Since the watershed land use is similar to the greater Subbasin, the Site likely has similar physicochemical concerns as those stated in the Basinwide Water Quality Plan. Potential sediment sources in the watershed include streambank erosion, bed scour, and runoff from agricultural fields. Potential sources of nutrients within the watershed are the livestock operation located east of the project along Schley Road, a livestock operation in the northeast quadrant of the watershed, the horse farm located west of the project, and runoff containing fertilizers applied to fields in the northern portion of the watershed. The suspected high nutrient load and lack of shade within the riparian corridor may contribute to elevated levels of chlorophyll a. There are, however, no observed algal blooms present within the project streams to indicate severe degradation in water quality or noticeably high levels of chlorophyll a. Although it is not mentioned in the Water Quality Plan, fecal coliform is another likely source of pollution within the watershed due to livestock operations. Water in UTI is stagnant because of vegetation on the channel bed that causes ponded water. Because no water quality data are available to evaluate the current level of physicochemical functioning, this function is not rated (Table 4). Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 7 March 2017 There is potential to improve the physicochemical functioning of the project streams. Water will flow over instream structures that will provide aeration, trees will be planted in the riparian zone to eventually shade and cool stream flow and help filter runoff, the stream will be reconnected to its floodplain and adjacent riparian wetlands to provide storage and treatment of overbank flows, and streambank erosion will be greatly reduced to nearly eliminate a source of sediment and nutrients. However, the potential improvements to physicochemical functioning will not happen immediately and some aspects will not occur until a mature canopy is established. Therefore, physicochemical improvements will not be included in the project success criteria for the seven-year monitoring period and the functional uplift potential is not rated (Table 4). 5.5 Biology There are no available biological data for the Site, however, the habitat conditions on the Site are poor. While the riffle material is well -mixed small gravel and the pools contain fine to coarse sand, the stream contains very little woody debris or organic material necessary to support diverse macroinvertebrate and fish communities. There are no downed trees or larger woody debris masses that would create habitat features. UT1 has some riffle -pool sequences, but the majority of stream length is choked with macrophytes, which results in stagnation and sedimentation, likely lowering dissolved oxygen levels and covering the bed habitat. Additionally, the perched culverts at the upstream limits of both Martin Dairy and UT1 act as a barrier to aquatic organism passage. While the riparian wetlands provide habitat diversity in the floodplain, they are regularly mowed, removing shade and refuge areas. The riparian zone of the project provides little habitat for terrestrial species other than pasture grass. However, because no data on the existing communities are available to evaluate the current level of biologic functioning, this function is not rated (Table 4). There is opportunity to improve the instream and riparian habitat in addition to the physicochemical function described in Section 5.4. Habitat will be improved by adding instream structures with a variety of rock and woody materials, adding woody bank revetments, reducing the abundance of nuisance macrophytes, providing a riparian buffer to shade the stream and improve terrestrial habitat, creating pools of variable depths, and cutting of sources of fine sediments. The culvert outlets will be addressed to improve aquatic organism passage. The biological response of the system will be tied to the physiochemical response post -restoration. As the physiochemical response may be delayed, the ultimate level of improvement in biology may not occur until after the completion of the seven-year monitoring period and, therefore, the functional uplift potential will be not rated (Table 4). 5.6 Overall Functional Uplift Potential Overall, the Martin Dairy Mitigation Site can be considered as Functioning -at -Risk but the functional uplift potential is a reclassification as Functioning (Table 4). This change in overall classification is related to improvements in hydraulics and geomorphology between the existing and proposed conditions. The hydrology function will not be improved by the project because watershed -scale reforestation would be required to drive improvement in this function. Physicochemical and biological improvements are a likely result of the project. However, there is no existing basis for classifying the existing condition of these functions and the likely improvements will occur gradually after construction. Therefore, these functions are not rated and not considered in the overall functional rating. Project goals are tied only to hydraulics and geomorphology. 5.7 Site Constraints to Functional Uplift An overhead electric utility line crosses the Site near the upstream extents of the project. The 30 -foot easement associated with the line will be an internal break in the conservation easement. This break is the only one within the project limits. The stream will be restored and stabilized through this break, however no trees will be included in the vegetation plan for this swath to allow maintenance access. Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 8 March 2017 The culverts at the upstream ends of the project are outside of the project limits. Due to this, repairs to hydraulic function and aquatic organism passage can only be addressed from the culvert outlets. There are no other man-made constraints within the project area that affect or reduce uplift potential. The valley width on the Site will allow for the development of pattern and channel dimensions to restore stable, functioning streams and there are no other known constraints to the functional uplift described above in this section. The degree to which the physicochemical and biology functions can improve on the Site is limited by the watershed conditions beyond the project limits, upstream water quality, and the presence of source communities upstream and downstream of the Site. 6.0 Regulatory Considerations Table 5, below, is a summary of regulatory considerations for the Site. These considerations are expanded upon in Sections 6.1-6.3. Table 5: Project Attribute Table Part 4 — Martin Dairy Mitigation Site Regulatory Considerations Parameters Applicable? Resolved?

PCN to be provided to DMS with Final Mitigation Plan 6.1 Biological and Cultural Resources A Categorical Exclusion for the Martin Dairy Mitigation Site was submitted to DMS on May 27, 2016, and approved on June 3, 2016. This document included investigation into the presence of threatened and endangered species on Site protected under The Endangered Species Act of 1973, as well as any historical resources protected under The National Historic Preservation Act of 1966. The biological conclusion for the Site, according to the Categorical Exclusion research and response by US Fish and Wildlife Service, is that the, "proposed action [in this project] is not likely to adversely affect any federally listed endangered or threatened species, their formally designated critical habitat, or species currently proposed for listing under the Act." All correspondence with USFWS and a list of Threatened and Endangered Species in Orange County, NC is included in Appendix 5. The conclusion for cultural resources according to the Categorical Exclusion research and response by the State Historic Preservation Office is that there are no historic resources that would be affected by this project. For additional information and regulatory communications please refer to the Categorical Exclusion document in Appendix 5. 6.2 FEMA Floodplain Compliance and Hydrologic Trespass Martin Dairy and UT1 are not FEMA mapped streams within the Site, as illustrated on the Orange County Flood Insurance Rate Map Panel 9896 and in Figure 7. Therefore, no modeling will be required for this project. Martin Dairy is mapped downstream of the Site at its confluence with Buckwater Creek. Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 9 March 2017 6.3 401/404 The natural low point in the valley for Martin Dairy is currently a wetland area. The proposed stream channel is re-routed through this area. Any wetlands within the conservation easement and outside of the limits of disturbance will be flagged with safety fence during construction to prevent unintended impacts. This will be denoted in the final construction plans on the Erosion and Sediment Control plan and Detail plan sheets, as well as in the project specifications. The majority of floodplain grading will be considered a temporary impact to wetlands. Wildlands expects a net gain of wetland area, as construction of the new channel will fill the majority of the old channel to the elevation of the existing wetlands and remove the overburden along the right bank of the existing Martin Dairy stream, creating a wider overall floodplain and riparian wetland area. Table 6 estimates the anticipated impacts to wetland areas on this project. The Pre -Construction Notification, including this data, will be provided to DMS in the Final Mitigation Plan.

The design is also intended to provide the expected outcomes in Section 7, though these are not tied to performance criteria. The project streams will be reconnected with an active floodplain and the channels will be reconstructed with stable dimension, pattern, and profile that will transport the water and sediment delivered to the system. The adjacent floodplain and riparian wetlands will be planted with native tree species. Instream structures will be constructed in the channels to help maintain stable channel morphology and improve aquatic habitat. The entire project area will be protected in perpetuity by a conservation easement. The design approach for this Site utilized a combination of analog and analytical approaches for stream restoration. Reference reaches were identified to serve as the basis for design parameters. Channels Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 11 March 2017 were sized based on design discharge hydrologic analysis. Designs were then verified and/or modified based on a sediment transport analysis. This approach has been used on many successful Piedmont and Slate Belt restoration projects (Underwood, Foust, Holman Mill, Maney Farm, and Agony Acres Mitigation Sites) and is appropriate for the simple goals and objectives for this Site. 8.2 Reference Streams Reference streams provide geomorphic parameters of a stable system, which can be used to inform design of stable channels of similar stream types in similar landscapes and watersheds. Five reference reaches were identified for this Site and used to support the design of Martin Dairy and UTI (Figure 9). These reference reaches were chosen because of their similarities to the Site streams including drainage area, valley slope, morphology, and bed material. The reference reaches are all located within the Carolina Slate Belt region of the Piedmont. Geomorphic parameters for these reference reaches are summarized located in Appendix 4. The references to be used for the specific streams are shown in Table 8. A description of each reference reach is included below. Table 8: Stream Reference Data Used in Development of Design Parameters — Martin Dairy Mitigation Site 8.2.1 Long Branch Long Branch is located in Orange County, northwest of Chapel Hill. Long Branch was previously identified as a reference and discussed in the Collins Creek Restoration Plan (KCI Technologies, 2007). The Long Branch watershed is low-density residential, agricultural, and forested land. The valley slope is 0.6% and channel slope is 0.4%. The stream maintains an entrenchment ratio above 2.5. Wildlands visited the reference site to verify the data presented in the KCI report. Two riffles were surveyed during the site visit. These riffles had a width to depth ratio of 9.4 and 8.0 with entrenchment ratios of 11.7 and 12.1, respectively. The cross-sections surveyed are more typical of E stream types, however KCI identified the stream as a C4 in their previous analysis. The stream likely varies between a C4 and E4. 8.2.2 Spencer Creek Reach 2 Spencer Creek Reach 2 is located in western Montgomery County near Ophir, NC, less than two miles from the Spencer Creek reference site (Buck Engineering, 2004). This site was classified as an E4 stream type and has a drainage area of 0.96 square miles. This reach flows through a mature forest and has a valley slope of 1.1% and a channel slope of 0.47%. The morphological parameters reported for the riffle cross-section include a width to depth ratio from 5.8 to 7.1 and an entrenchment ratio of 5.5 and 10.2. 8.2.3 Foust Creek The Foust Creek reference reach is located approximately 600 feet upstream of the northernmost conservation easement boundary on the Foust Creek Mitigation Site in Alamance County, NC. It was identified by Wildlands in the Foust Creek Mitigation Site 2014 Mitigation Plan (Wildlands Engineering, 2014). Foust Creek has a gravel bed and a valley slope of 0.75%. The Foust Creek reference reach is classified as a Rosgen C4 stream type. This reach flows through a mature forest and although it is stable it lacks sinuosity. It was used in this project to inform the cross-section and profile parameters.

The morphological parameters reported for the riffle cross-section include a width to depth ratio from 5.8 to 7.1 and an entrenchment ratio of 5.5 and 10.2. 8.2.3 Foust Creek The Foust Creek reference reach is located approximately 600 feet upstream of the northernmost conservation easement boundary on the Foust Creek Mitigation Site in Alamance County, NC. It was identified by Wildlands in the Foust Creek Mitigation Site 2014 Mitigation Plan (Wildlands Engineering, 2014). Foust Creek has a gravel bed and a valley slope of 0.75%. The Foust Creek reference reach is classified as a Rosgen C4 stream type. This reach flows through a mature forest and although it is stable it lacks sinuosity. It was used in this project to inform the cross-section and profile parameters. Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 12 March 2017 8.2.4 UT to Polecat Creek The UT to Polecat Creek reference reach is located in northern Randolph County. The site was identified by Wolf Creek Engineering and used as a reference reach for the Holly Grove Restoration Site (Wolf Creek Engineering, 2007). Wildlands conducted a site visit and reference reach survey in March, 2013, to confirm the geomorphic parameters listed in the Holly Grove Restoration Site Plan. The UT to Polecat Creek reference reach is classified as a Rosgen E4 stream type. 8.2.5 UT to Varnals Creek The UT to Varnals Creek reference reach is located in south central Alamance County, NC near the Cane Creek Mountains. The site was identified by Ecologic Associates and used as a reference reach for the Reedy Branch Stream Restoration Site (EcoLogic Associates, 2002). Wildlands visited UT to Varnals Creek in September 2014 and visually confirmed that the land use is unchanged from reported conditions and that the stream is laterally and vertically stable. Wildlands conducted a detailed morphological survey in October 2014. UT to Varnals Creek has a drainage area of 0.41 square miles and is classified as a Rosgen B4/E4b stream type for the majority of the reach. UT to Varnals Creek has a similar channel and valley slope to UT1. 8.2.6 Agony Acres On -Site Reference Reach (UT1-Reach 3) The Agony Acres On -Site Reference Reach (UT1— Reach 3) is located in northeast Guildford County, NC. It was identified by Wildlands as a high quality preservation component of the nearby Agony Acres Mitigation Site in the March 2014 Mitigation Plan (Wildlands Engineering, 2014) and was used as a reference reach for that project. It was selected as a reference reach due to its similarity in slope and drainage area to UT1. A detailed survey was conducted in March of 2013. UTI — Reach 3 has a drainage area of 0.3 square miles and classified as an E4 stream type. 8.3 Design Channel Morphological Parameters Reference reaches were a primary source of information to develop the pattern and profile design parameters for the streams. Ranges of pattern parameters were developed within the reference reach parameter ranges with some exceptions based on best professional judgement and knowledge from previous projects. The full range of reference reach data is located in Appendix 4. We found the lower limit of some of these parameters to be too low to build a stable system. They are likely low in reference reaches due to the presence of a mature forest and root system that both influences and stabilizes channel pattern and profile. For example, radius of curvature ratio in reference data has a lower limit of 1.1 and the meander width ratio had a minimum of 1.0, however we have found that for C/E channels, these ratios should be above 1.8 and 2.4 respectively to naturally dissipate energy through meander bends during high flow events to limit impacts of shear stress on streambanks. The lower limits of the radius of curvature ratio and meander width ratio are based on values used for many years and on many successful designs. Reference reaches were also used to inform the design of the cross-sections on the streams. The streams were designed with pool widths to be approximately 1.3 times the width of riffles to provide space for point bars and riffle pool transition zones. Designer experience was used for pool design as well. Pool depths were designed to be a minimum of 1.5 times deeper than riffles to provide habitat variation. Cross-section parameters such as area, depth, and width were designed based on the design discharge and stable bank slopes. The width to depth ratio was increased beyond some of the reference parameters for UTI in order to provide stable bank slopes prior to the development of a fully vegetated streambank. Key morphological parameters for the Site are listed in Tables 9 and 10 for Martin Dairy and UT1 respectively. Complete morphological tables for existing, reference, and proposed conditions are located in Appendix 4.

These factors have led to the impairments discussed in Sections 3 and 4. To address these impairments and the stressors on the system, restoration is proposed for Martin Dairy and UT1. Both channels were designed to be Rosgen stream type C4/E4, with width -to -depth ratios on the low end of the typical range for that stream type. Narrow and deeper channels are common in slate belt reference reaches; however, the reference channels have established vegetation that maintain stability on steeper streambanks. The design channels will begin with flatter side slopes that will be more stable without established vegetation. Constructing channels with higher width -to -depth ratios and flatter side slopes will allow for sediment deposition on the banks and bank protection as the streambank vegetation establishes. The complete design morphological parameters for Martin Dairy and UT1 are located in Appendix 4 and summaries of key parameters are shown in Tables 9 and 10. 8.4 Design Discharge Analysis Multiple methods were used to develop bankfull discharge estimates for each of the project restoration reaches: the NC Rural Piedmont Regional Curve (Harman et al., 1999), NC Piedmont/Mountain Regional Curve (Walker, unpublished), a Wildlands Regional USGS Flood Frequency Analysis, a Site Specific Reference Reach Curve, existing bankfull indicators using Manning's Equation, and data from previous successful design projects. The resulting values were compared and best professional judgment was used to determine the specific design discharge for each restoration reach. 8.4.1 Published Regional Curve Data Discharge was estimated using the published NC Rural Piedmont Curve (Harman et al., 1999) as well as the updated curve for rural Piedmont and mountain streams, also known as the Walker Curve (Walker, unpublished). Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 15 March 2017 8.4.2 Wildlands Regional USGS Flood Frequency Analysis Wildlands developed a regional flood frequency analysis tool that tailored the USGS 2009 publication Magnitude and Frequency of Rural Floods in the Southeastern United States, through 2006 to the Piedmont of North Carolina. Of the 103 stations referenced in the publication, 23 were used in the development of the tool. To fill gaps in data, five additional stations were added by Wildlands to represent streams with drainage areas less than one square mile. The Hosking and Walls homogeneity test was performed in Ro to identify a selection of hydrologically similar gages based on homogeneity (Hosking and Walls, 1993). The gages used were: • USGS 02096740 — Gun Branch near Alamance, NC (DA = 4.06 miZ) • USGS 02096846 — Cane Creek near Orange Grove, NC (DA = 7.54 mit) • USGS 02097010 — Robeson Creek near Pittsboro, NC (DA = 1.71 mit) • USGS 02101030 — Falls Creek near Bennett, NC (DA = 3.43 miZ) • USGS 0210166029 — Rocky River at SR1300 near Crutchfield Crossroads, NC (DA = 7.42 miZ) The data from these 28 gage stations were used to develop flood frequency curves for the 1.2 -year and 1.5 -year recurrence interval discharges. These relationships can be used to estimate discharge of those recurrence intervals for ungauged streams in the same hydrologic region, and were solved for each project reach's discharge with the drainage area as the input. 8.4.3 Site Specific Reference Reach Curve Six reference reaches were identified for this project (Section 4.2). Each reference reach was surveyed to develop information for analyzing drainage area -discharge relationships as well as development of design parameters. Stable cross-sectional dimensions and channel slopes were used to compute a bankfull discharge with the Manning's equation for each reference reach. The resulting discharge values were plotted with drainage area and compared the other discharge estimation methods. 8.4.4 Existing Bankfull Indicators (Manning's Equation) A riffle cross-section was surveyed on each design reach on the Site, totaling three cross-sections. In addition to this, three cross-sections were surveyed on the reaches directly upstream of the project. Bankfull indicators were identified in the field during this survey. Manning's equation was used to calculate a corresponding discharge using the pebble count information for roughness and the survey data for channel slope. The upstream cross-sections off the project were used to calibrate bankfull depth. It can be difficult to identify clear bankfull indicators on incised and degraded channels, so the highest quality indicators were used to calibrate others. The highest quality indicators were identified on UTI and on Martin Dairy upstream of the project site. 8.4.5 Design Discharge Analysis Summary A design goal of Martin Dairy is to maintain the existing riparian wetlands on the right floodplain while encouraging the development of riparian wetlands on the left floodplain. Removing the existing dredge spoil material within the floodplain is the first step in this process. The second is establishing a design discharge that will support the riparian wetlands. The results of the design discharge analysis provided a range of discharge values with the NC Rural Piedmont Regional Curve producing the highest and the Walker Curve producing the lowest. The NC Rural Piedmont Regional Curve discharge estimates were higher than the other estimation methods on Martin Dairy. The Walker Curve discharge estimates were lower (up to 29 cubic feet per second (cfs)) than all other estimation methods. For these reasons, the regional curve estimation methods were not considered further in the selection of a design discharge for Martin Dairy. There was concurrence between the Wildlands Regional USGS Flood Frequency Analysis (1.2 -year event), the existing bankfull indicators using Manning's Equation, and the Site Specific Reference Reach Curve for Martin Dairy Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 16 March 2017 Reaches 1 and 2. These three values were averaged and then that value was compared to other successful projects in the Slate Belt with similar drainage areas and similar design goals (Agony Acres, Holman Mill, and Maney Farm). Those project values confirmed the selected design discharge. The design discharge analysis for UTI produced a fairly even spread of values across the estimation methods and lacked concurrence between any group of methods. Because of this, the aforementioned past projects within the Slate Belt were used for further evaluation. Creating a rating curve from past successful projects of similar drainage area gave a design discharge of 24 cfs for UT1. This value was incredibly close to the average of all estimation methods (26 cfs). For this reason, 24 cfs was chosen as the design discharge. Table 11 gives a summary of the discharge analysis. Figure 10 illustrates the design discharge data. Table 11: Summary of Design Discharge Analysis — Martin Dairy Mitigation Site 8.5 Sediment Transport Analysis As discussed in Section 3.1.2, small Slate Belt streams are generally low bedload sediment supply systems. To confirm that the streams on this Site are low bedload streams, Wildlands performed a qualitative assessment of the sediment load volume and sources in the project watershed. For this project, the watershed was assessed through aerial photography and field reconnaissance to characterize past and current land cover and potential sediment sources. There are two prominent potential sediment sources within the watershed: runoff from agricultural fields and streambank erosion and bed scour. There is evidence of streambank erosion on UTI upstream of the project on the adjacent farm. However, the pond at the downstream end of the property serves as a sink for the excess sediment and limits the amount of sediment delivered to the Site. There is minimal evidence of streambank erosion from the upstream reaches of Martin Dairy delivering large sediment loads. Ponds on the northwest branch serve as a sink for sediment input and the northeast branch is in a wooded area. On-site streams were visually inspected several times during 2015 and 2016 to qualitatively assess aggradation and degradation within the channels. Streams exhibited evidence of on-going fluvial erosion on stream banks on Martin Dairy and UT1. There was no evidence of sediment deposition and accumulation throughout these reaches, indicating that aggradation within the reaches is not an issue.

To confirm that the streams on this Site are low bedload streams, Wildlands performed a qualitative assessment of the sediment load volume and sources in the project watershed. For this project, the watershed was assessed through aerial photography and field reconnaissance to characterize past and current land cover and potential sediment sources. There are two prominent potential sediment sources within the watershed: runoff from agricultural fields and streambank erosion and bed scour. There is evidence of streambank erosion on UTI upstream of the project on the adjacent farm. However, the pond at the downstream end of the property serves as a sink for the excess sediment and limits the amount of sediment delivered to the Site. There is minimal evidence of streambank erosion from the upstream reaches of Martin Dairy delivering large sediment loads. Ponds on the northwest branch serve as a sink for sediment input and the northeast branch is in a wooded area. On-site streams were visually inspected several times during 2015 and 2016 to qualitatively assess aggradation and degradation within the channels. Streams exhibited evidence of on-going fluvial erosion on stream banks on Martin Dairy and UT1. There was no evidence of sediment deposition and accumulation throughout these reaches, indicating that aggradation within the reaches is not an issue. Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 17 March 2017 Once the project is constructed, on-site sediment sources will be addressed by protecting streambanks and reducing shear stress in the channels. The watershed assessment indicates that the bedload supply is not high enough to cause the project streams to be capacity limited. The focus of sediment transport analysis for this design was verify that the designed channels will be stable over time and have the ability to pass sediment from the watersheds. A competence analysis was performed on the streams to aid in the development of the final channel designs. 8.5.1 Competence Analysis Competence analyses were performed iteratively during design for each of the restoration reaches by comparing shear stress associated with the design bankfull discharge, proposed channel dimensions, and proposed channel slopes with the size distribution of the existing bed load. The analysis utilized standard equations based on a methodology using the Shields (1936) curve and Andrews (1984) equation described by Rosgen (2001). Channel slope and design dimensions were varied until the resulting design verified that the stream reach could move the bed load supplied to the stream. The results of the analysis are shown in Table 12. Table 12: Results of Competence Analysis — Martin Dairy Mitigation Site Martin Dairy - R1 Martin Dairy - R2 UTI Dbkf (ft) 1.10 1.20 0.7 Schan (ft/ft) 0.0050 0.0055 0.0140 Bankfull Shear Stress, t (Ib/sq ft) 0.33 0.41 0.60 Dmax Bar/Subpavement (mm) 55 75 38 Dcrit (ft) 1.7 2.2 0.4 Scrit (ft/ft) 0.0079 0.0099 0.0078 Movable particle size (mm) 67.9 1 78.7 1 104.1 Predicted Shear Stress to move Dmax 0.25 0.38 0.15 The initial competence analysis was based on the size material naturally found in the stream in order to mimic potential bed load. The results were used to inform further design of the reach. The excess shear noted on UT1 influenced the design of rock and wood step structures to provide grade control and increase roughness within the channel. Riffles with larger materials, such as chunky riffles, were also integrated into the design as grade control. A second competence analysis was done to size the proposed Dso and Dloo for the constructed riffles on all stream reaches. Riffles materials was sized so that the reconstructed channels will not produce enough shear stress to entrain the largest particles in these structures. This will ensure a stable pavement while allowing for bed load material to be active within the system. 8.6 Project Implementation The majority of Martin Dairy will be raised through Priority I restoration (Table 13). This will raise the water table, improve hydrologic connection to the riparian wetlands, allow for frequent inundation of the floodplain, and a reduction of shear stress on the channel. The majority of UT1 will be a Priority II due to restrictions in Site topography and the elevation of the upstream culvert in relation to the floodplain. A floodplain will be graded in at a bankfull elevation. The floodplain will not meander along with the stream pattern but will be relatively straight. Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 18 March 2017 Table 13: Functional Impairments and Restoration Approach — Martin Dairy Mitigation Site Resource Functional Impairments Restoration Approach Martin Dairy Incision, erosion, lack of riparian vegetation, lack of habitat Restoration — Priority I UT1 Incision, erosion, lack of riparian vegetation, lack of habitat Restoration — Priority II Martin Dairy has been separated into two reaches for the restoration design, separated by the confluence with UT1. The proposed stream will be realigned to the low point in the existing valley and the top of bank is set at an elevation matching the base of the overburden material on the existing floodplain. The perched culvert at the top of the reach will allow for a Priority 1 restoration approach through this area. The alignment travels through an existing wetland that formed between the toe of the valley slope and the overburden. The overburden material will be removed during construction to fill the old channel it is anticipated that additional wetlands will form across the valley floor creating an interconnected stream and wetland complex on the Site. UT1 will also be relocated into the natural low point in its valley. Due to the upstream culvert elevation, UT1 will follow a Priority II approach. A floodplain will be excavated at a lower level so that the stream bed is not raised for this short reach. A structure will be placed at the top of the reach to hold the bed elevation at that of the culvert invert so as to improve aquatic organism passage on this reach. Martin Dairy and UT1 will be sinuous (K=1.14) and the beds will be comprised of riffle -pool sequences with some log and rock drop structures. In -stream structures will include various types of constructed riffles, log sills, boulder sills, lunker logs, and j -hooks. The structures will reinforce channel stability and serve as habitat features. The constructed riffles will be comprised of excavated on-site riffle material from the adjacent hillslopes where the presence of Tatum Silt loam soil indicates bedrock is located (Figure 5). The riffles will also incorporate woody brush material and logs. The diverse range of constructed riffle types will provide grade control, diversity of habitat, and will create varied flow vectors. Log -j-hooks will deflect flow vectors away from banks while adding to habitat diversity. Log sills will be used to allow for small grade drops across pools and provide extra grade control. At select outer meander bends, the channel banks will be constructed with brush toe revetments to reduce erosion potential, encourage pool maintenance, and provide varied pool habitat. Lunker logs in combination with sod mats will also be used to provide pool habitat variability. Due to the availability of sod on site, it will be used extensively to provide immediate bank protection. The concept plan for Site restoration is illustrated in Figure 8. Wildlands has completed several projects within the Slate Belt and has found that riffle grade control material can be harvested from weathered parent material on valley sideslopes to mitigate for the natural lack of grade control. This method, along with the introduction of woody debris, has been successful at providing a heterogeneous mixture of riffle material that increases channel roughness and improves channel hydraulics and geomorphology. The gradation of material provides varied pore spaces within the riffles and structures, which benefits hyporheic exchange processes and habitat niche formation. According to soil descriptions, the Tatum silt loam, located along the right valley wall of Martin Dairy, contains weathered bedrock at a depth of 50 inches. This area will be used to source habitat and grade control structures during construction. One of the secondary objectives of this project will be to improve aquatic organism passage through the culvert at the upstream end of Martin Dairy by raising the stream bed to elevation of the culvert and eliminating the existing nick point barrier. Also as part of this project, a new culvert is to be added to the Site, downstream of the conservation easement, to allow the landowner access to the back half of their parcel. The culvert will be designed as to not impede aquatic organism passage onto the Site. Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 19 March 2017 The restoration of Martin Dairy is likely to increase the wetland footprint on-site to include the old channel bed and newly created floodplain. This, along with the development of a riparian forest, should increase the Site's ability to cycle and store nutrients. The efficacy of nutrient cycling is likely to increase as the forest matures and develops a seasonal input of organic material into the system. An estimate of the percent reduction in nitrogen (TN) and phosphorus (TP) was made using a simplified version of the Tar -Pamlico Nutrient Calculation Sheet, which estimates typical nutrient loading based on land use. Pre - project conditions reflected managed pasture while post -project conditions modeled the project area as wooded. The area within the channel was not included in either model (calculations in Appendix 4). The worksheet estimated that the land use conversion would result in a 54% reduction in TN and a 77% reduction in TP from on-site sources. This equates to an annual load reduction of 5.3 lbs of TN and 2.3 lbs of TP. These numbers do not include the probable reductions associated with riparian wetlands. Despite the potential increase in the Site's ability to cycle nutrients post -restoration, the Site may still be considered to be functioning -at -Risk with a trend towards Functioning in regards to pollutants. The restoration will not address pollutant sources within the greater watershed, and the Site is not large enough to provide substantial enough nutrient sinks or denitrification from hyporheic exchange. The Site is connected to a wooded parcel downstream. Once a riparian buffer is established on-site, mammalian and avian species will likely migrate to the newly forested area. 8.7 Vegetation and Planting Plan The objective of the planting plan is to establish, over time, a thriving riparian buffer composed of native tree species. This restored buffer will improve riparian habitat, help the restored streams stay stable, shade the streams, and provide a source for LWD and organic material to the streams. The Site will also generate Riparian Buffer Credits as well as SMUs for the Neuse 01 CU in accordance with 15A NCAC 02B .0295 (Effective November 1, 2015). The Site will be planted to the extents of the conservation easement, to include the additional buffer areas as shown in Figure 11. Riparian buffers will be seeded and planted with early successional native vegetation (a mixture of trees and shrubs). The specific species composition to be planted was selected based on the community type, observation of occurrence of species in riparian buffers adjacent to the Site, best professional judgement on species establishment and anticipated Site conditions in the early years following project implementation, and the requirement of a minimum of four species according to Rule 0295. Species chosen for the planting plan are listed on Sheet 2.0 of the Draft Plans located in Appendix 6. The Draft Plans also contain additional guidance on planting zones, Site preparation, and Site stabilization during construction. The riparian buffer areas will be planted with bare root seedlings. In addition, the top of banks will be planted with live stakes and the channel toe will be planted with multiple herbaceous species. Livestakes will not be located on UT1 due to the size of the channel. Permanent herbaceous seed will be spread on streambanks, floodplain areas, and all disturbed areas within the project easement. Permanent herbaceous seed will also be placed within the internal easement break for the utility crossing. To help ensure tree growth and survival, soil amendments may be added to areas of the floodplain along Martin Dairy where overburden material is removed. Soil tests will be performed in areas of cut and fertilizer and lime will be applied based on the results. Additionally, topsoil will be stockpiled, reapplied, and disked before permanent seeding and planting activities take place. Species planted as bare roots will be planted a 12 -foot by 6 -foot spacing (targeted densities after monitoring year 3 are 320 stems per acre). Live stakes will be planted on channel banks at 6 -foot spacing. Live stakes will be installed above base flow elevation. The presence of invasive species on Martin Dairy Mitigation Site is limited to the streambanks on existing streams. The most prevalent species, Chinese privet (Logustrum sinese), is spread throughout Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 20 March 2017 the length of the project. Multiflora rose (Rosa multiflora) is also scattered along the existing stream banks, but in much lower quantities. Cattail (Typha latifolia) is present in small quantities and is limited to the stagnant area on UT1. The goal of this project is to treat and remove as much existing invasive species as possible before and during construction. Post construction, the presence and extents of invasive species will be monitored. Treatment of invasive species will continue as necessary throughout the life of the project to ensure project stability and success of the riparian and streambank vegetation. Additional monitoring and maintenance issues regarding vegetation a Sections 9 and 10 and Appendix 7. 8.8 Project Risk and Uncertainties This project is low risk. The land use surrounding the project is currently in hay production, so there is not a potential for accidental livestock access. There is one break in the easement for the maintenance of an overhead utility line. This area may be mowed or maintained periodically by Piedmont Electric Membership Corporation. It is very unlikely that utility maintenance personnel would cross the stream, as there is access to the western utility pole by the gravel drive located at the north end of the project. A riffle was designed in this easement break to ensure channel bank and bed stability. Due to the rural nature of the area, there is very little risk that changes in land use upstream in the project watershed would alter the hydrology or sediment supply to the degree that the project is put at risk. The easement is excluded from stream credit calculations. 9.0 Performance Standards The stream and wetland performance standards for the project will follow approved performance standards presented in the DMS Mitigation Plan Template (version 2.3, 12/18/2014), the Annual Monitoring Template (April 2015), and the Stream Mitigation Guidelines issued April 2003 by the USACE and DWR. Annual monitoring and semi-annual site visits will be conducted to assess the condition of the finished project. Specific performance standard components are proposed for stream morphology, hydrology, and vegetation. Performance standards will be evaluated throughout the seven-year post - construction monitoring. 9.1 Streams 9.1.1 Dimension Riffle cross-sections on the restoration reaches should be stable and should show little change in bankfull area, maximum depth ratio, and width -to -depth ratio. Per DMS guidance, bank height ratios shall not exceed 1.2 and entrenchment ratios shall be at least 2.2 for restored C and E channels to be considered stable. All riffle cross-sections should fall within the parameters defined for channels of the designed stream type. If any changes do occur, these changes will be evaluated to assess whether the stream channel is showing signs of instability. Indicators of instability include a vertically incising thalweg or eroding channel banks. Changes in the channel that indicate a movement toward stability or enhanced habitat include a decrease in the width -to -depth ratio in meandering channels or an increase in pool depth. Remedial action would not be taken if channel changes indicate a movement toward stability. 9.1.2 Pattern and Profile Visual assessments and photo documentation should indicate that streams are remaining stable and do not indicate a trend toward vertical or lateral instability. 9.1.3 Substrate Channel substrate materials will be sampled with the pebble count method along Martin Dairy and UT1. Restoration reaches should show maintenance of coarser materials in the riffle features and smaller Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 21 March 2017 particles in the pool features. A reach -wide pebble count will be performed in each restoration reach each monitoring year for classification purposes. A pebble count will be performed at each surveyed riffle to characterize the pavement. 9.1.4 Photo Documentation Photographs should illustrate the Site's vegetation and morphological stability on an annual basis. Cross- section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal photos should indicate the absence of persistent of mid -channel bars or vertical incision. Grade control structures should remain stable. Deposition of sediment on the bank side of vane arms is preferable. Maintenance of scour pools on the channel side of vane arms is expected. 9.1.5 Bankfull Events The occurrence of bankfull events and geomorphically significant events will be documented throughout the monitoring period. Two bankfull flow events must be documented within the seven-year monitoring period. The two bankfull events must occur in separate years. Also, two geomorphically significant events must be documented during the monitoring period as well. For these purposes, a geomorphically significant event is a flow event that is between 66% of the two-year discharge. These events may occur in the same year. Stream monitoring will continue until performance standards in the form of two bankfull events in separate years and two additional geomorphically significant events have been documented. 9.2 Vegetation Vegetative performance for riparian buffers associated with the stream restoration component of the project (buffer widths 0 — 50ft) will be in accordance with the Stream Mitigation Guidelines issued April 2003 by the USACE and DWR. The success criteria is an interim survival rate of 320 planted stems per acre at the end of monitoring year three (MY3), 260 stems per acre at the end of monitoring year 5 (MY5) and a final vegetation survival rate of 210 stems per acre at the end of monitoring year 7 (MY7). A separate buffer monitoring report will be submitted to NCDWR no later than December 31 of each year for a minimum of five consecutive years after the first full growing season (MY1, 2, 3, 4, and 5). At the completion of monitoring year 5, DMS will request closeout of the buffer portion of the project, assuming vegetation criteria is met. Vegetative performance for buffer restoration areas (Figure 11) will be in accordance with 15A NCAC 02B .0295(n)(2)(B), € and (n)(4) (effective November 1, 2015). To meet success, areas generating buffer mitigation credits shall include a minimum of four native hardwood tree species or four native hardwood tree and native shrub species, where no one species is greater than 50 percent of stems, and have a survival of 260 planted stems per acre at the end of the required monitoring period (MY5) (no interim success criteria required). In order for the monitoring to be terminated, DWR must provide a written approval of vegetation success of buffer restoration areas generating buffer credit. The extent of invasive species coverage will be monitored and controlled as necessary throughout the required monitoring period (MY5 or MY7). 9.3 Visual Assessments Visual assessments should support the specific performance standards for each metric as described above. 10.0 Monitoring Plan The Site monitoring plan has been developed to ensure that the required performance standards are met and project goals and objectives are achieved. Annual monitoring data will be reported using the Martin Dairy Mitigation Site Final Mitigation Plan DMS ID No.97087 Page 22 March 2017 DMS Annual Monitoring Reporting Template (April 2015). The monitoring report shall provide project data chronology that will facilitate an understanding of project status and trends, ease population of DMS databases for analysis and research purposes, and assist in close-out decision making. Using the DMS As -Built Baseline Monitoring Report Template (February 2014), a baseline monitoring document and as -built record drawings of the project will be developed within 60 days of the planting completion and monitoring installation on the restored site. Monitoring reports will be prepared in the fall of each monitoring year and submitted to DMS by November 30. These reports will be based on the DMS Annual Monitoring Template (April 2015) and Closeout Report Template (March 2015). DMS monitoring reports will be submitted in monitoring years 1, 2, 3, 4, and 7. Closeout monitoring period will be seven years beyond completion of construction or until performance standards have been met. A separate buffer monitoring report will be submitted annually to NCDWR as described in section 9.2, in monitoring years 1,2,3,4, and 5. Also, a separate as -built report will be developed within 30 days of the planting completion and submitted to NCDWR. All reports submitted to NCDWR will follow the typical NCDWR format. Closeout monitoring period for buffers will be five years beyond completion of construction or until performance standards have been met. Table 14, below, describes how the monitoring plan is set up in order to verify project goals and objectives have been achieved.

Mr. Win Taylor Address: 497 Bramson Court, Suite 104 Mt.

Orange County, North Carolina Parcel Index Numbers: 9896830483 and 9896839111. Waters on-site drain into Buckwater Creek, an indirect tributary of the Neuse River. Indicate Which of the Following Apply: A. Preliminary Determination X There are waters, including wetlands, on the above described project area, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The waters, including wetlands, have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process, including determining compensatory mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary determination is not an appealable action under the Regulatory Program Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved JD, which is an appealable action, by contacting the Corps district for further instruction. _ There are wetlands on the above described property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). However, since the waters, including wetlands, have not been properly delineated, this preliminary jurisdiction determination may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is merely an effective presumption of CWA/RHA jurisdiction overall of the waters, including wetlands, at the project area, which is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters of the U.S. on your property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. B. Approved Determination _ There are Navigable Waters of the United States within the above described property subject to the permit requirements of Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act (CWA)(33 USC § 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. _ There are waters of the U.S., including wetlands, on the above described project area subject to the permit requirements of Section 404 of the Clean Water Act (CWA) (33 USC § 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. _ We recommend you have the waters of the U.S. on your property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. _ The waters of the U.S., including wetlands, on your project area have been delineated and the delineation has been verified by the Corps. If you wish to have the delineation surveyed, the Corps can review and verify the survey upon completion. Once verified, this survey will provide an accurate depiction of all areas subject to CWA and/or RHA jurisdiction on your property which, provided there is no change in the law or our published regulations, may be relied upon for a period not to exceed five years. _ The waters of the U.S., including wetlands, have been delineated and surveyed and are accurately depicted on the plat signed by the Corps Regulatory Official identified below on . Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. _ There are no waters of the U.S., to include wetlands, present on the above described project area which are subject to the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. _ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (CAMA). You should contact the Division of Coastal Management in Morehead City, NC, at (252) 808-2808 to determine their requirements. Basis For Determination: On June 13, 2016, Wildlands Engineering, Inc. submitted a preliminary iurisdictional determination (JD) to our office for review. Representatives from the United States Army Corps of Engineers (Corps) and Wildlands Engineering, Inc. participated in an on-site field verification conducted on July 28, 2016. During this investigation the Corps requested additional information required to accuracy describe and delineate waters within the Martin Dairy Mitigation Site. Final revisions were received by our office on August 5, 2016. Based on a review of the June 13, 2016 report submitted to our office, on-site field verification on July 28, 2016, and final revisions received on August 2016, this office has determined that 1,840 linear feet of perennial stream channel and 2.848 acres of emergent wetland are present within the Martin Dairy Mitigation Site proiect boundary. Refer to the enclosed Preliminary Jurisdictional Determination Form, Aquatic Resource Table, and Figure 3 Site Map for a detailed summary of waters on-site. E. Attention USDA Program Participants This delineation/determination has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the particular site identified in this request. The delineation/determination may not be valid for the wetland conservation provisions of the Food Security Act of 1985. If you or your tenant are USDA Program participants, or anticipate participation in USDA programs, you should request a certified wetland determination from the local office of the Natural Resources Conservation Service, prior to starting work.

PROJECT LOCATION(S) AND BACKGROUND INFORMATION: (USE THE ATTACHED TABLE TO DOCUMENT MULTIPLE WATERBODIES AT DIFFERENT SITES) State: NC County/parish/borough: Orange City: Hillsborough Center coordinates of site (lat/long in degree decimal format): Lat. 36.123290N, Long. 79.00402° W. Universal Transverse Mercator: Name of nearest water body: Buckwater Creek Identify (estimate) amount of waters in the review area: Non -wetland waters: 1,840 linear feet: width (ft) and/or acres. Cowardin Class: Riverine Stream Flow: Perennial Wetlands: 2.848 acres. Cowardin Class: PEM Name of any water bodies on the site that have been identified as Section 10 waters: Tidal: Non -Tidal: E. REVIEW PERFORMED FOR SITE EVALUATION (CHECK ALL THAT APPLIES): ® Office (Desk) Determination. Date: December 9, 2016 ® Field Determination. Date(s): July 28, 2016 1. The Corps of Engineers believes that there may be jurisdictional waters of the United States on the subject site, and the permit applicant or other affected party who requested this preliminary JD is hereby advised of his or her option to request and obtain an approved jurisdictional determination (JD) for that site. Nevertheless, the permit applicant or other person who requested this preliminary JD has declined to exercise the option to obtain an approved JD in this instance and at this time. 2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General Permit (NWP) or other general permit verification requiring "pre -construction notification" (PCN), or requests verification for a non -reporting NWP or other general permit, and the permit applicant has not requested an approved JD for the activity, the permit applicant is hereby made aware of the following: (1) the permit applicant has elected to seek a permit authorization based on a preliminary JD, which does not make an official determination of jurisdictional waters; (2) that the applicant has the option to request an approved JD before accepting the terms and conditions of the permit authorization, and that basing a permit authorization on an approved JD could possibly result in less compensatory mitigation being required or different special conditions; (3) that the applicant has the right to request an individual permit rather than accepting the terms and conditions of the NWP or other general permit authorization; (4) that the applicant can accept a permit authorization and thereby agree to comply with all the terms and conditions of that permit, including whatever mitigation requirements the Corps has determined to be necessary; (5) that undertaking any activity in reliance upon the subject permit authorization without requesting an approved JD constitutes the applicant's acceptance of the use of the preliminary JD, but that either form of JD will be processed as soon as is practicable; (6) accepting a permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps permit authorization based on a preliminary JD constitutes agreement that all wetlands and other water bodies on the site affected in any way by that activity are jurisdictional waters of the United States, and precludes any challenge to such jurisdiction in any administrative or judicial compliance or enforcement action, or in any administrative appeal or in any Federal court; and (7) whether the applicant elects to use either an approved JD or a preliminary JD, that JD will be processed as soon as is practicable. Further, an approved JD, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331, and that in any administrative appeal, jurisdictional issues can be raised (see 33 C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary to make an official determination whether CWA jurisdiction exists over a site, or to provide an official delineation of jurisdictional waters on the site, the Corps will provide an approved JD to accomplish that result, as soon as is practicable. This preliminary JD finds that there "may be" waters of the United States on the subject project site, and identifies all aquatic features on the site that could be affected by the proposed activity, based on the following information: SUPPORTING DATA. Data reviewed for preliminary JD (check all that apply - checked items should be included in case file and, where checked and requested, appropriately reference sources below): ® Maps, plans, plots or plat submitted by or on behalf of the applicant/consultant: Wildlands Engineering, Inc., submitted a Jurisdictional Determination Request on June 13, 2016, with revisions received on August 5, 2016. ® Data sheets prepared/submitted by or on behalf of the applicant/consultant. ® Office concurs with data sheets/delineation report. ❑ Office does not concur with data sheets/delineation report. ❑ Data sheets prepared by the Corps: ❑ Corps navigable waters' study: ❑ U.S. Geological Survey Hydrologic Atlas: ❑ USGS NHD data. ❑ USGS 8 and 12 digit HUC maps. ® U.S. Geological Survey map(s).

DWR forms can be found in this appendix and in the digital submission to DMS. DWR forms were completed by Wildlands for Martin Dairy and UTI. On April 5, 2016 a DWR representative came to the site and classified E1, an ephemeral reach, on the property and provided the total stream score to Wildlands. DWR noted that riparian buffer credit could be applied to this reach during design if so desired. Wildlands has not requested credit for buffer along this reach. Table 1: DWR Form Summary— Martin Dairy Mitigation Site 1. During the proposal stage for this project and at the time of the DWR stream classification UT1 was named UT2.

JAY ZIMMERMAN Dll'ec'!OJ' DWR Project* 2016-0366 Re: Site Viability for Buffer Mitigation & Nutrient {Offset -- Martin Dairy Creek Located on Schley Rd across from Martin Hill Ln, Hillsborough, NC {grange County Dear John, On April 5, 2016, Katie Merritt, with the Division of Water Resources (DWR), assisted you and ethers from Wildlands Engineering Inc. at the proposed Martin Dairy Mitigation Site (Site) in Hillsborough, NC. The Site is located in the Upper Falls Watershed for the: Neuse River Basin within the 8 -digit Hydrologic Unit Code 03020201, The Site is being proposed as part of a full - delivery stream restoration project for the Division of Mitigation Services (RFP #16-006477). The Interagency Review Team (IRT) was also present onsite. At your request, Ms. Merritt, performed a site assessment of the two features onsite, which are more accurately shown in the attached aerial signed by Ms. Merritt on April 15, 2016. If approved, mitigating this site could provide stream mitigation credits, riparian buffer credits and/or nutrient offset credits. Ms. Merritt's evaluation of the features for buffer and nutrient offset mitigation pursuant to Rule 15A NCAC 02B .0295 (effective November 1, 2015) and Rule 15A NCAC 02B .0240 is provided below: Martin Dairy Creek and UT2 • Features are streams. • Land use within the riparian areas (0 to +/- 200') adjacent to both sides of the streams comprise of managed fescue. • The riparian areas along the streams are viable for riparian restoration and suitable for buffer mitigation only. • Stream restoration is proposed on these streams. Therefore, riparian restoration efforts shall occur in conjunction with the stream restoration and not before. • For nutrient offset viability to be determined, the landowner must provide proof in writing that the land is being used for agriculture or has been used for agriculture previously. Dates supported by photos or other written records trust be included to document any uses of the land not observed during the site visit on April 5, 2015. 401 and Buffer Penmitting Unit 1617 Mail Service Center, Raleigh, North Carolina 27699-1817 Location: 512 N. Salisbury St. Raleigh, North Carolina 27604 Phone: 919.807-63001 FAX: 519-807-6484 Internet: www.ncwaterquality.org Martin Dairy Creels April 15, 2016 Page 2 of 2 Ephemeral Reach • The feature is a modified natural channel located within a topographic crenulation indicative of a natural drainage on the 1:24,000 quad topographic map prepared by the U.S. Geologic Survey. Ms. Merritt rated the channel using the NC DWR Stream Identification Form Version 4.11. The rating she received on the form was a 14.5; Therefore, the feature is ephemeral. • Land use within the riparian areas (0 to +1- 200') adjacent to both sides of the streams comprise of managed fescue. • The riparian areas along the streams are viable for riparian restoration and suitable for buffer mitigation only. • For nutrient offset viability to be determined, the landowner must provide proof in. writing that the land is being used for agriculture or has been used for agriculture previously. Dates, supported by photos or other written records, must be included to document any uses of the land not observed during the site visit on April 5, 2016. Maps showing the project site and the features are provided and signed by Ms. Merritt on April 15, 2016. This letter should be provided in all future mitigation plans for this Site. In addition, all vegetative plantings, performance criteria and mitigation requirements for riparian restoration must following the requirements in 15A NCAC 02B .0295 to be eligible for buffer and nutrient offset credits. For any areas depicted as not being viable for nutrient offset credit, one could propose a different measure other than riparian restoration, along with supporting calculations and sufficient detail to support estimates of load reduction, for review by the DWR to determine viability for nutrient offset according to 15A NCAC 02B .0240. Please contact Katie Merritt at (919)-807-6371 if you have any questions regarding this correspondence.

As the Martin Dairy Mitigation Site is a full -delivery project; an EDR Radius Map Report with Geocheck was ordered for the site through Environmental Data Resources, Inc. on April 14, 2016. Neither the target property, nor immediately adjacent properties, were listed in any of the Federal, State, or Tribal environmental databases searched by EDR. Overall, there was one Leaking Underground Storage Tank (LUST) site and one Underground Storage Tank (UST) sites found in the databases searched. The LUST site is the same physical location as the UST site, 7500 Schley Road. These two locations are approximately 1,500 feet downstream from the specific project area. Overall, the assessment revealed no evidence of any "recognized environmental conditions" in connection with the target property. The Executive Summary of the EDR report is included in the Appendix. The full report is available if needed. National Historic Preservation Act (Section 106) The National Historic Preservation Act declares a national policy of historic preservation to protect, rehabilitate, restore, and reuse districts, sites, buildings, structures, and objects significant in American architecture, history, archaeology, and culture, and Section 106 mandates that federal agencies take into account the effect of an undertaking on a property that is included in, or is eligible for inclusion in, the National Register of Historic Places. Wildlands Engineering, Inc. (Wildlands) requested review and comment from the State Historic Preservation Office (SHPO) with respect to any archeological and architectural resources related to the Martin Dairy Mitigation Site on April 15, 2016. SHPO responded on May 12, 2016 and stated they were aware of no historic resources that would be affected by the project. All correspondence related to Section 106 is included in the Appendix. Uniform Relocation Assistance and Real Property Acquisition Policies Act (Uniform Act) These acts, collectively known as the Uniform Act, provide for uniform and equitable treatment of persons displaced from their homes, businesses, non-profit associations, or farms by federal and federally -assisted programs, and establish uniform and equitable land acquisition policies. Martin Dairy Mitigation Site is a full -delivery project that includes land acquisition. Notification of the fair market value of the project property and the lack of condemnation authority by Wildlands was included in the signed option agreement for the project property. A copy of the relevant section of the option agreement is included in the Appendix. Endangered Species Act (ESA) Section 7 of the ESA requires federal agencies, in consultation with and with the assistance of the Secretary of the Interior or of Commerce, as appropriate, to ensure that actions they authorize, fund or carry out are not likely to jeopardize the continued existence of threatened or endangered species or result in the destruction or adverse modification of critical habitat for these species. The Orange County listed endangered species include the bald eagle (Haliaeetus leucocephalus) (BGPA), dwarf wedgemussel (Alasmidonta heterodon), smooth coneflower (Echinacea laevigata) and the Michaux's sumac (Rhus michauxii). The USFWS does not currently list any Critical Habitat Designations for any of the Federally -listed species within Orange County. Wildlands requested review and comment Martin Dairy Mitigation Site Categorical Exclusion 1V DMS #97087 from the United States Fish and Wildlife Service (USFWS) on April 15, 2016 in respect to the Martin Dairy Mitigation Site and its potential impacts on threatened or endangered species. USFWS responded on May 5, 2016 and stated the "proposed action is not likely to adversely affect any federally listed endangered or threatened species, their formally designated critical habitat or species currently proposed for listing under the Act". All correspondence with USFWS is included in the Appendix. As a result of a pedestrian survey conducted on September 3, 2015, no individual species, suitable habitat or critical habitat were found to exist on the site for any of the listed species. It was determined that the project would result in "no effect" on the listed species. Farmland Protection Policy Act (FPPA) The FPPA requires that, before taking or approving any federal action that would result in conversion of farmland, the agency must examine the effects of the action using the criteria set forth in the FPPA, and, if there are adverse effects, must consider alternatives to lessen them. The Martin Dairy Mitigation Site includes the conversion of prime farmland. As such, Form AD -1006 has been completed and submitted to the Natural Resources Conservation Service (NRCS). The completed form and correspondence documenting its submittal is included in the Appendix. Fish and Wildlife Coordination Act (FWCA) The FWCA requires consultation with the USFWS and the appropriate state wildlife agency on projects that alter or modify a water body. Reports and recommendations prepared by these agencies document project effects on wildlife and identify measures that may be adopted to prevent loss or damage to wildlife resources. The Martin Dairy Mitigation Site includes stream restoration. Wildlands requested comment on the project from both the USFWS and the North Carolina Wildlife Resources Commission (NCWRC) on April 15, 2016. NCWRC responded on May 3, 2016 and stated they "do not anticipate the project to result in significant adverse impacts to aquatic and terrestrial wildlife resources". The USFWS responded on May 5, 2016 and had no objections to the project. All correspondence with the two agencies is included in the Appendix. Migratory Bird Treaty Act (MBTA) The MBTA makes it unlawful for anyone to kill, capture, collect, possess, buy, sell, trade, ship, import, or export any migratory bird. The indirect killing of birds by destroying their nests and eggs is covered by the MBTA, so construction in nesting areas during nesting seasons can constitute a taking. Wildlands requested comment on the Martin Dairy Stream Mitigation Site from the USFWS in regards to migratory birds on April 15, 2016. USFWS responded on May 5, 2016, but had no comments regarding migratory birds. All correspondence with USFWS is included in the Appendix.

Therefore, if you have projects that occur within the Raleigh Field Office's area of responsibility (see attached county list), you no longer need to contact the Raleigh Field Office for a list of federally -protected species. Our web page contains a complete and frequently updated list of all endangered and threatened species protected by the provisions of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.)(Act), and a list of federal species of concern' that are known to occur in each county in North Carolina. Section 7 of the Act requires that all federal agencies (or their designated non-federal representative), in consultation with the Service, insure that any action federally authorized, funded, or carried out by such agencies is not likely to jeopardize the continued existence of any federally -listed endangered or threatened species. A biological assessment or evaluation may be prepared to fulfill that requirement and in detennining whether additional consultation with the Service is necessary. In addition to the federally -protected species list, information on the species' life histories and habitats and information on completing a biological assessment or evaluation and can be found on our web page at http://www,fws.gov/raleigh. Please check the web site often for updated information or changes. ' The term "federal species of concern" refers to those species which the Service believes might be in need of concentrated conservation actions. Federal species of concern receive no legal protection and their designation does not necessarily imply that the species will eventually be proposed for listing as a federally endangered or threatened species. However, we recommend that all practicable measures be taken to avoid or minimize adverse impacts to federal species of concern. If your project contains suitable habitat for any of the federally -listed species known to be present within the county where your project occurs, the proposed action has the potential to adversely affect those species, As such, we recommend that surveys be conducted to determine the species' presence or absence within the project area. The use of North Carolina Natural Heritage program data should not be substituted for actual field surveys. If you determine that the proposed action may affect (i.e., likely to adversely affect or not likely to adversely affect) a federally -protected species, you should notify this office with your determination, the results of your surveys, survey methodologies, and an analysis of the effects of the action on listed species, including consideration of direct, indirect, and cumulative effects, before conducting any activities that might affect the species. If you determine that the proposed action will have no effect (i.e., no beneficial or adverse, direct or indirect effect) on federally listed species, then you are not required to contact our office for concurrence (unless an Enviromnental Impact Statement is prepared). However, you should maintain a complete record of the assessment, including steps leading to your determination of effect, the qualified personriel conducting the assessment, habitat conditions, site photographs, and any other related articles. With regard to the above -referenced project, we offer the following remarks. Our comments are submitted pursuant to, and in accordance with, provisions of the Endangered Species Act. Based on the infon-nation provided and other information available, it appears that the proposed action is not likely to adversely affect any federally -listed endangered or threatened species, their formally designated critical habitat, or species currently proposed for listing under the Act at these sites. We believe that the requirements of section 7(a)(2) of the Act have been satisfied for your project. Please remember that obligations under section 7 consultation must be reconsidered if: (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered; (2) this action is subsequently modified in a manner that was not considered in this review; or, (3) a new species is listed or critical habitat determined that may be affected by the identified action. However, the Service is concerned about the potential impacts the proposed action might have on aquatic species. Aquatic resources are highly susceptible to sedimentation. Therefore, we reconunend that all practicable measures be taken to avoid adverse impacts to aquatic species, including implementing directional boring methods and stringent sediment and erosion control measures. An erosion and sedimentation control plan should be submitted to and approved by the North Carolina Division of Land Resources, Land Quality Section prior to construction. Erosion and sedimentation controls should be installed and maintained between the construction site and any nearby dawn -gradient surface waters. In addition, we recommend maintaining natural, vegetated buffers on all streams and creeks adjacent to the project site. The North Carolina Wildlife Resources Commission has developed a Guidance Memorandum (a copy can be found on our website at (http://www.fws.gov/raleigh) to address and mitigate secondary and cumulative impacts to aquatic and terrestrial wildlife resources and water quality. We recommend that you consider this document in the development of your projects and in completing an initiation package for consultation (if necessary), 2 We hope you find our web page useful and informative and that following the process described above will reduce the time required, and eliminate the need, for general correspondence for species' lists. If you have any questions or comments, please contact Kathy Matthews of this office at (919) 856-4520 ext. 27.

The following guidance is provided for your information. Projects are subject to the Farmland Protection Policy Act (FPPA) requirements if they may irreversibly convert farmland (directly or indirectly) to non- agricultural use and are completed by a federal agency or with assistance from a federal agency. Farmland means prime or unique farmlands as defined in section 1540(c)(1) of the FPPA or farmland that is determined by the appropriate state or unit of local government agency or agencies with concurrence of the Secretary of Agriculture to be farmland of statewide local importance. For the purpose of FPPA, farmland includes prime farmland, unique farmland, and land of statewide or local importance. Farmland subject to FPPA requirements does not have to be currently used for cropland. It can be forestland, pastureland, cropland, or other land, but not water or urban built-up land. Farmland does not include land already in or committed to urban development or water storage. Farmland already in urban development or water storage includes all such land with a density of 30 structures per 40 -acre area. Farmland already in urban development also includes lands identified as urbanized area (UA) on the Census Bureau Map, or as urban area mapped with a tint overprint on the United States Geological Survey (USGS) topographical maps, or as urban -built-up on the United States Department of Agriculture (USDA) Important Farmland Maps. The area in question meets one or more of the above criteria for Farmland. Farmland area will be affected or converted. Enclosed is the Farmland Conversion Impact Rating form AD 1006 with PARTS II, IV and V completed by NRCS. The corresponding agency will need to complete the evaluation, according to the Code of Federal Regulation 7CFR 658, Farmland Protection Policy Act. The Natural Resources Conservation Service is an agency of the Department of Agriculture's Natural Resources mission.

The Martin Dairy Mitigation Site is being developed to provide in-kind mitigation for unavoidable stream channel impacts. Several sections of channel have been identified as significantly degraded. This will be a stream restoration project only. The site has historically been disturbed due to agricultural use, primarily for livestock production. We thank you in advance for your timely response and cooperation. Please feel free to contact us with any questions that you may have concerning this project. Sincerely, Ruby M. Davis Environmental Scientist Attachment: USGS Topographic Map Aerial Map 1430 South Mint Street, Suite 104, Charlotte, NC 28203 - (P) 704-332-7754 � (F) 704-332-3306 North Carolina Wildlife Resources Commission Gordon Myers, Executive Director 3 May 2016 Ms. Ruby M. Davis Wildlands Engineering 1430 South Mint Street, Suite 104 Charlotte, NC 28203 Subject: Martin Dairy Mitigation Site, Orange County, North Carolina Dear Ms. Davis: Biologists with the North Carolina Wildlife Resources Commission have reviewed the subject information. Our comments are provided in accordance with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667e) and North Carolina General Statutes (G.S. 113-131 et seq.). The proposed project includes stream restoration. Several sections of channel have been identified as significantly degraded. The site has been used primarily for livestock production. The mitigation site will provide in-kind mitigation for unavoidable stream impacts. The project site includes an unnamed tributary to Buckwater Creek in the Neuse River basin. Stream restoration projects often improve water quality and aquatic habitat. Establishing native, forested buffers in riparian areas will help protect water quality, improve aquatic and terrestrial habitats, and provide a travel corridor for wildlife species. Provided measures are taken to minimize erosion and sedimentation from construction/restoration activities, we do not anticipate the project to result in significant adverse impacts to aquatic and terrestrial wildlife resources. Thank you for the opportunity to review this proposed project. If we can provide further assistance, please contact our office at (336) 449-7625 or shari.bryant(kncwildlife.org.

General Construction Notes for All Reaches 1. All erosion and sediment control practices shall comply with the North Carolina Erosion and Sediment Control Planning and Design Manual. 2. Contractor will install pump -around systems to divert flow while working in live, flowing channels. The Contractor shall operate and maintain the pump -around system 24 hours a day until all disturbed areas are stabilized. The disturbed area within the pump around must be stabilized with temporary seeding, mulch and erosion control matting by the end of each work day. Contractor shall not remove pump -around systems and advance to the next work area until the current work area is completed and stabilized. 3. No material from the off-line proposed stream channel excavation may be backfilled into the adjacent existing stream channel until the newly -constructed proposed stream section is completed, stabilized, and the stream flow has been diverted into it, not even if that section of old/ existing stream is being pumped. 4. In areas without a pump -around system, Contractor shall disturb only as much channel bank as can be stabilized with temporary seeding, mulch, and a sod mat or erosion control matting by the end of each work day. 5. Clearing and grubbing activities shall not extend more than 150 linear feet ahead of in -stream work. 6. When crossing an active section of new or old stream channel, a Timber Mat shall be installed according to the details and specifications. 7. All graded areas with slopes steeper than 3:1 will be stabilized within seven (7) working days. All other areas will be stabilized within 14 working days. 8. Locations for staging and stockpile areas and temporary stream crossings have been provided on the Plans. Additional or alternative staging and/or stockpile areas and stream crossings may be used by the Contractor provided that all practices comply with the North Carolina Erosion and Sediment Control Planning and Design Manual and that the areas are approved by the Engineer prior to implementation. 9. Various types of constructed riffles are specified on the plans. Contractor shall build the specific types of constructed riffles at locations shown on the Plans. Changes in constructed riffle type must be approved by the Engineer. 10. Contractor is to make every effort to avoid damaging or removing existing trees. 11. Under no circumstances will the Contractor exceed the limits of disturbance as shown on the Plans. 12. Trees are to be harvested only in the area represented on the plans, west of the easement area. Trees can be harvested from the first 10 feet of the wood line and should be cut as close to the ground as possible. The land owner will mark trees which will NOT be harvested prior to commencement of construction. 13. The construction entrance on the southernmost end of the project should remain in place after construction Existing Features Existing Property Boundary ------------------------------ Existing 5' Major Contour Existing V Minor Contour is completed, per landowner request. Initial Site Preparation 1. Contact North Carolina "One Call" Center (1.800.632.4949) before any excavation. 2. Contact Division of Energy, Mineral and Land Resources (919-791-4200) before any work begins on the project and notify them of the start date. 3. Mobilize equipment and materials to the Site. 4. Identify and establish construction entrance, staging and stockpile areas, haul roads, silt fence, tree protection fencing, safety fencing, and temporary stream crossings as indicated on the Plans for work areas. Note: Construction access will enter the site from Schley Road using two specified construction entrances. These entrances are within temporary construction entrance easements. 5. All haul roads shall be monitored for sediment loss daily. In the event of sediment loss, silt fence or other acceptable sediment and erosion control practices shall be installed. Silt fence outlets shall be located at points of low elevation or a minimum spacing of 150 ft. 6. Set up temporary facilities, locate equipment within the staging area, and stockpile materials needed for the initial stages of construction within the stockpile area(s). 7. Install and maintain an onsite rain gauge and log book to record the rainfall amounts and dates. Complete the self -inspection as required by NCDEQ permit. Martin Dairy Creek Reach 1, Martin Dairy Creek Reach 2, and UT1 Construction 8. Perform any necessary clearing and grubbing in phases as work progresses. Bank vegetation and vegetation immediately adjacent to live channels shall be left undisturbed as long as possible. Remove all non-native and invasive vegetation prior to beginning the channel construction. Take care with vegetation marked for transplant from the old channel to new channel. Do not disturb transplant vegetation until time of transplant. 9. Construction of all channels are to be done in the dry. Construction should generally progress from upstream to downstream to prevent sediment runoff from upstream construction affecting completed downstream reaches. Use a pump around as shown on the plans and discussed in the General Notes. 10. Where feasible, more than one offline section may be constructed concurrently. Offline sections shall be tied online sequentially from downstream to upstream. 11. As work progresses, remove and stockpile the top three inches of soil from the active grading area. Stockpiled topsoil shall be kept separate for onsite replacement prior to floodplain seeding. 12. Construct the proposed stream channel to the grade specified in the cross-sections and profile. Transfer coarse material from abandoned channel riffles to new channel riffles utilizing a pump -around when doing so. 13. Grade the adjacent floodplain area according to grades shown on the plan. 14. Install in -stream structures (riffles, angled log sill, log J -hook, lunker log, and boulder sill) and in -bank Proposed Features CE - CE - CE Proposed Conservation Easement TCE TCE Proposed Temporary Construction Entrance Proposed Stream Alignment %�So bioengineering such as brush toe and sod mats after channel grading is completed according to details and specifications. 15. Sod mats should be used in lieu of coir fiber matting to stabilize all stream banks on site as the preferential stabilization method. Sod mats shall be installed according to sod mat detail. Coir fiber matting may be used where sod mats are not available or if coir fiber matting is preferred at the discretion of the Engineer. 16. Seed (with specified temporary seed and permanent seed mix) and straw mulch areas where the coir fiber matting is to be installed. 17. Install coir fiber matting according to plans and specifications. 18. Backfill abandoned channel sections with stockpiled soil according to the grades shown on the Plans. Non-native and invasive vegetation (e.g. Chinese privet and multiflora rose) shall be removed from the existing channel prior to backfilling. 19. Prepare floodplain for seeding by applying stockpiled topsoil to the floodplain between bankfull elevation and the grading limits, ripping, and raking/smoothing. Seed with specified temporary and permanent seed mix and mulch. Any areas within the conservation easement that have not been graded shall be treated according to the planting plan. 20. If at any time circumstances should arise where water has been turned into the new channel and additional work must be done on the floodplain, erosion control devices will be installed to protect the new channel from sedimentation. 21. Once all phases of channel and floodplain construction are complete, prepare the floodplain areas for planting per the specifications. 22. Install livestakes and herbaceous plugs along the stream banks according to the plans and specifications. Construction Demobilization 23. Remove temporary stream crossings. 24. The Contractor shall ensure that the site is free of trash and leftover materials prior to demobilization of equipment from the site. 25. Complete the removal of any additional stockpiled material from the site. 26. Demobilize grading equipment from the site. 27.

Plan \71P[A7 � Martin Dairy Culvert Crossing Station 119+81 4.7 IN N Q Appendix 7 Maintenance Plan 1.0 Maintenance Plan The site shall be monitored on a regular basis and a physical inspection of the site shall be conducted a minimum of once per year throughout the post -construction monitoring period until performance standards are met. These site inspections may identify site components and features that require routine maintenance. Routine maintenance should be expected most often in the first two (2) years following site construction and may include the following: Tablel: Maintenance Plan — Martin Dairy Mitigation Site Component/Feature Maintenance through project close-out Routine channel maintenance and repair activities may include chinking of in -stream structures to prevent piping, securing of loose coir matting, and supplemental Stream installations of live stakes and other target vegetation along the channel. Areas where storm water and floodplain flows intercept the channel may also require maintenance to prevent bank erosion. Beaver dams that inundate the stream channels shall be removed and the beaver shall be trapped if deemed necessary. Vegetation shall be maintained to ensure the health and vigor of the targeted community. Routine vegetation maintenance and repair activities may include Vegetation supplemental planting, pruning, mulching, and fertilizing. Exotic invasive plant species shall be controlled by mechanical and/or chemical methods. Any vegetation control requiring herbicide application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations. Site boundaries shall be identified in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries may be identified by fence, marker, Site boundary 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. Martin Dairy Mitigation Site DMS ID No. 97087 Page 1 Appendix 8 Credit Release Schedule 1.0 Credit Release Schedule All credit releases will be based on the total credit generated as reported by the as -built survey of the mitigation site. Under no circumstances shall any mitigation project be debited until the necessary DA authorization has been received for its construction or the District Engineer (DE) has otherwise provided written approval for the project in the case where no DA authorization is required for construction of the mitigation project. The DE, in consultation with the Interagency Review Team (IRT), will determine if performance standards have been satisfied sufficiently to meet the requirements of the release schedules below. In cases where some performance standards have not been met, credits may still be released depending on the specifics of the case. Monitoring may be required to restart or be extended, depending on the extent to which the site fails to meet the specified performance standard. The release of project credits will be subject to the criteria described as follows: Table A: Credit Release Schedule — Stream Credits — Martin Dairy Mitigation Site Monitoring Interim Total Credit Release Activity Year Release Released 0 Initial Allocation — see requirements below 30% 30% First year monitoring report demonstrates performance 1 10% 40% standards are being met Second year monitoring report demonstrates performance 2 standards are being met 10% o 50/0 (additional 10% released at second bankfull event in a separate year) (60%) Third year monitoring report demonstrates performance 60% 3 standards are being met o 10% (70%) Fourth year monitoring report demonstrates performance 65% 4 standards are being met 5% (75%) Fifth year monitoring report demonstrates performance 75% 5 standards are being met 10% (85%) Sixth year monitoring report demonstrates performance 80% 6 standards are being met 5% (90%) Seventh year monitoring report demonstrates performance 90% 7 standards are being met and project has received closeout approval o 10% (100%) 1.1 Initial Allocation of Released Credits The initial allocation of released credits, as specified in the mitigation plan can be released by DMS without prior written approval of the DE upon satisfactory completion of the following activities: a. Approval of the final Mitigation Plan. b. Recordation of the preservation mechanism, as well as a title opinion acceptable to the USACE covering the property. c. Completion of project construction (the initial physical and biological improvements to the mitigation site) pursuant to the mitigation plan; per the DMS Instrument, construction means that a mitigation site has been constructed in its entirety, to include planting, and an as -built report has been produced. As -built reports must be sealed by an engineer prior to project closeout, if appropriate but not prior to the initial allocation of released credits. d. Receipt of necessary DA permit authorization or written DA approval for projects where DA permit issuance is not required. Martin Dairy Mitigation Site DMS ID No. 97087 Page 1 1.2 Subsequent Credit Releases All subsequent credit releases must be approved by the DE, in consultation with the IRT, based on a determination that required performance standards have been achieved. For stream projects a reserve of 10% of a site's total stream credits shall be released after two bankfull events have occurred, in separate years, provided the channel is stable and all other performance standards are met. In the event that less than two bankfull events occur during the monitoring period, release of these reserve credits shall be at the discretion of the IRT. As projects approach milestones associated with credit release, the DMS will submit a request for credit release to the DE along with documentation substantiating achievement of criteria required for release to occur. This documentation will be included with the annual monitoring report.
