EEP is proposing the Moores Fork Stream Mitigation Project (project) to fulfill stream mitigation requirements accepted by this program for the Upper Yadkin River Basin (CU 03040101). Through this project, EEP proposes to restore, enhance and preserve approximately 20,915 linear feet (LF) of Moores Fork and fifteen previously unnamed tributaries (UTs), provide livestock fencing and alternative water sources to keep livestock out of the streams, remove invasive plant species across the project, and establish native riparian buffers. Based on preliminary estimates from the design proposed in this Mitigation Plan, the Moores Fork Stream Mitigation Project will net 13,203 stream mitigation credits through a combination of restoration, enhancement I and 11, and preservation. This Mitigation Plan describes specific project goals and objectives as they relate to EEP's programmatic goals (including watershed planning), provides baseline data on the existing conditions of Moores Fork and its UTs at the project site, and describes the methodologies that were used develop the preliminary design. The Mitigation Plan also outlines the performance standards and monitoring protocol that will be used to evaluate the project's success, and it details long term management strategies for protecting and maintaining the restoration site in perpetuity. This Mitigation Plan has been written in conformance with the requirements of the following: • Federal rule for compensatory mitigation project sites as described in the Federal Register Title 33 Navigation and Navigable Waters Volume 3 Chapter 2 Section § 332.8 paragraphs (c)(2) through (c)(14). • EEP In -Lieu Fee Instrument signed and dated July 28, 2010 These documents govern EEP operations and procedures for the delivery of compensatory mitigation.

Draft Final Mitigation Plan March 2012 1.0 RESTORATION PROJECT GOALS AND OBJECTIVES EEP develops River Basin Restoration Priorities (RBRP) to guide its restoration activities within each of the state's 54 cataloging units. RBRPs delineate specific watersheds that exhibit both the need and opportunity for wetland, stream and riparian buffer restoration. These watersheds are called Targeted Local Watersheds (TLWs) and receive priority for EEP planning and restoration project funds. The 2009 Upper Yadkin RBRP ( www .nceep.net/services /restplans /Upper Yadkin RBRP 2009.pdfl identified the Stewarts Creek 14 -digit HUC 03040101110010 as a TLW. Agriculture is the primary land use in the watershed (36% agriculture land cover and only 3% impervious cover) and the RBRP identified degraded riparian buffers as the major stressor to water quality. There are 12 permitted animal operations and 37% of the Stewarts Creek watershed has non - forested riparian buffers. In addition to being located within an EEP TLW, the Moores Fork drainage was identified as a priority subwatershed for stream restoration and agricultural BMPs during the initial Upper Yadkin - Ararat River local watershed planning (LWP) initiative conducted by EEP [EcoEngineering, 2008]. The site assessment phase of the project identified other stressors as well, including elevated water temperatures, excessive nutrient inputs, channel incision, bank erosion and sediment deposition. The Moores Fork Stream Mitigation Project was identified as an opportunity to improve water quality and aquatic and terrestrial habitats within the TLW. The project goals address stressors identified in the TLW and include the following: • Improve water quality in Moores Fork and the UTs through reductions in sediment and nutrient inputs from local stressors /sources; • Create conditions for dynamic equilibrium of water and sediment movement between the supply reaches and project reaches; • Promote floodwater attenuation and secondary functions associated with more frequent and extensive floodwater contact times; • Improve in- stream habitat by increasing the diversity of bedform features; • Enhance and protect native riparian vegetation communities; and • Reduce fecal, nutrient, and sediment loads to project streams by promoting and implementing livestock best management practices. The project goals will be addressed through the following project objectives: • Restoration of the dimension, pattern, profile of approximately 1,378 LF of Moores Fork and 2,143 LF of two UTs; • Restoration of the dimension and profile (Enhancement 1) of the channel for approximately 4,043 LF of Moores Fork and 2,810 LF of three UTs; • Limited channel work coupled with livestock exclusion, gully stabilization, invasive species control and buffer planting (Enhancement 11) on approximately 5,998 LF along five UTs; • Livestock exclusion fencing and other best management practice installations; • Invasive plant species control measures across the entire project wherever necessary; and • Preservation of approximately 4,543 LF relatively un- impacted forested streams in permanent conservation easement. Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 1 2.0 SITE SELECTION 2.1 Directions to Site The Moores Fork project site is located northwest of Mount Airy in Surry County, North Carolina. To access the site from Asheville, take 1 -40 East towards Statesville to Exit 152B. Merge on 1 -77 North toward Elkin and travel approximately 49 miles. Take Exit 100 (North Carolina 89) toward Mt. Airy and Galax. Turn right onto North Carolina 89 (West Pine Street) and travel approximately 2 miles. Turn left onto Pine Ridge Road and travel approximately 0.2 mile and turn right onto Horton Road. The project site is located on both sides of Horton Road. A site vicinity map (Figure 1) and USGS topographic map (Figure 2) are attached for review. Latitude and longitude for the site are 36.506671 N and 80.704115 W, respectively. 2.2 Historical Conditions and Future Land Use Trends Reference is made in the following discussions to project reaches and design stationing as shown on the attached preliminary plans (Appendix D). The project site falls within five parcels encompassing 461 acres. One of the parcels (11.7 acres) is owned by William L. Horton, Jr. and the other four parcels are owned by Maple Ridge Farm. Maple Ridge Farm is an operating dairy and a portion of the Horton parcel is used as pasture for the dairy cows. An 18 -acre area comprised of two outparcels is located near the center of the site. Dairy operations are focused at a cluster of barns, silage pits and small buildings in a 4 -acre area near the farm entrance along Horton Road. A few other barns and sheds are located elsewhere on the property. The majority of the stream length targeted for channel modifications lacks a robust vegetative buffer. Enhancement and preservation are proposed for stream reaches in areas of the site that do contain functional buffers, including much of the Barn Tributary drainage, UTs 6 and 7, portions of the Silage Tributary drainage, and the right floodplain over the downstream half of Moores Fork. Vegetation in the Barn Tributary drainage includes mature trees (greater than 18 inches dbh) and dense mountain laurel. On the downstream Moores Fork floodplain, several trees in the 12 to 18 inches dbh size range are present. Based on a review of aerial photograph of the project site, land use and the extent of cleared land have not changed significantly since at least 1982 (Figure 5). Between 1948 (Figure 6) and 1982, upland areas in the Corn, Silage and Barn tributary drainages were cleared of trees and converted to pasture or row crop fields. The permanent stream crossings on the project site include a clear -span bridge over Moores Fork near the mid -point of the project reach and two culverts at the upstream and downstream ends of the Corn Tributary. While it is difficult to be certain, the aerial photographs indicate the crossing locations have remained consistent since at least 1982. Judging by the deck materials, the bridge over Moores Fork appears to have been improved or replaced within the past 10 years. The landowners indicated that they have reinforced the stream banks upstream of the abutments on multiple occasions over the past several years. In October 2006, Surry County issued Land Use Plan 2015 which describes growth, land use changes and future development policies through 2015. The Moores Fork site is located at the divide between a rural land use area and a rural growth area. A rural growth area is defined as being appropriate for medium density residential development. Land to the west of the dividing line, leading to upland areas of the Moores Fork watershed, is designated as rural land, with a best use of agriculture, low density residential, forestry and other similar practices. Technical Memorandum Task 2, Upper Yadkin Basin Local Watershed Plan identified the Moores Fork sub - watershed as a high priority for stream restoration, presumably because of its low population density, agricultural land uses and potential for improvement. Current and projected future land use for this watershed supports an ecosystem investment at this site. Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 2 TIM !

Dairy and farming operations over the past several decades have deforested riparian buffers and allowed direct livestock access to stream, leading to elevated temperatures and nutrients which are the primary stressors identified for this sub - watershed with the TLW (EcoEngineering, 2008). Moores Fork has also been impacted by channel straightening and dredging throughout much of the project reach, and levee construction in the upstream 1,800 LF. The levee is located on the left bank, is generally 1 to 2 feet high and has the effect of limiting floodplain access. Widespread bank erosion and mid - channel sediment deposition are visible throughout Moores Fork. With the exception of the upstream 1,700 LF of Moores Fork, cattle currently have direct access to the project streams. The majority of the cattle impacts are located along Moores Fork between stations 17 +50 and 36 +00, over the downstream half of the Silage Tributary and along both of the Cow Tributaries. Runoff from barns, fields and silage pits near the headwaters of the Silage Tributary, the Cow Tributaries and UT1 has contributed to deep gullies forming. Bank heights of 6 feet or more are common in the upstream 2,000 LF of the Silage Tributary and the upstream 200 LF of UT1, above the intermittent break; bank heights on the Cow Tributaries are generally less than 3 feet. The silage pits will be relocated away from surface waters and measures to manage runoff quantity and quality from upland areas will be incorporated into a farm management plan that will be implemented in conjunction with the stream enhancement efforts. The Corn Tributary buffers have been impacted by past logging, by recent clearing for an overhead electric line, and by farm road construction, but impacts are generally limited to upland areas well away from the channel. The downstream 100 LF reach of the Corn Tributary is incised and the right bank has been cleared of woody vegetation. The Pond Tributary is impacted by the dam upstream of the project reach, by a culvert on a farm road downstream of the dam, and by cattle feeding area near its confluence with Moores Fork. The primary impacts on the Barn Tributary are associated with a small dam that previously impounded the upstream 150 LF; the dam was breached several years ago, but woody buffer vegetation has yet to establish in the former impoundment and the short reach downstream. Some recent logging has impacted the buffer on the right side of the Barn Tributary, and logging debris is present in the channel in a few locations. The most significant impacts to UT1 are due to runoff from an upland corn field, which has formed two deep gullies above the headwaters and contributed excess fine sediment to the downstream reach. Non - native plant species, particularly privet, multiflora rose and honeysuckle, are present in wooded areas of the site. The most severely impacted areas are located in the Silage Tributary drainage. The Corn Tributary drainage, and to a lesser extent the Barn Tributary drainage, are also impacted. Table 1 summarizes stressors and ecological services needing enhancement in the project area. Table 1.

Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 9 2.4 Evolutionary Trends Appendix C includes a two -page inventory map showing areas of significant bank erosion, bar formation, gully formation and debris jams. Moores Fork appears to have been straightened and shifted to the edge of its valley between stations 19 +00 and 38 +00. There is also evidence of possible channelization or lateral migration between stations 56 +00 and 62 +00. This assessment is supported by observations of the floodplain topography, which shows low points in the floodplain and wetland areas indicative of relict channel sections offset 100 feet or more from the current channel. Additional supporting data were gathered from five of six hand auger borings in the floodplain that encountered gravel indicative of the one -time creek bed at depths of 3.7 to 4.7 feet below existing grade. Based on a review of aerial photographs, this straightening and /or lateral migration was completed to its current conditions prior to 1948. The shortened stream length and resulting steepening of the channel profile likely set an incision process in motion. Bedrock is visible throughout much of Moores Fork and it appears that the bedrock has limited the depth and extent of channel incision. Observations of a gravel layer in the bank near the downstream end of the project indicate the channel has down -cut 1 to 2 feet. The channel modifications, incision and subsequent widening have created bank stability and sediment transport problems, particularly when combined with buffer vegetation removal and livestock trampling. Moores Fork appears to be less than halfway on a trajectory from a C -type steam to an F -type stream, as evidenced by the following (refer to project site photographs, section 2.5): • Extensive, ongoing bank erosion; • Leaning and fallen trees; • Channel cross sectional areas up to nearly three times the estimated bankfull areas; • Bank heights up to twice the bankfull depth; and • Frequent, large mid - channel sediment bars. The Soil Survey of Surry County indicates most of the rock in the area strikes northeast- southwest and dips northwest. The dominant soils at the site are in the Fairview series, which are residual sandy clays, the products of in -situ weathering of the parent bedrock. The residual soils are overlain by alluvial soils in the Moores Fork floodplain. Even the relatively modest incision observed throughout much of the project reach has confined large flows to the channel, which in turn has led to bank erosion, widening and mid - channel sediment deposition. While most obvious in Reach 2 through a pasture immediately upstream of the bridge, this scenario is ongoing in the wooded reaches downstream of the bridge as well. Left unchecked, this process of widening and mid - channel deposition will likely continue as leaning trees fall and expose erodible soils. The evolutionary trend suggests that the stream will migrate laterally and form a new cross section until the system eventually reaches equilibrium with its water and sediment supply. Flow in the Pond Tributary is affected greatly by the upstream pond located about 200 feet upstream of the project reach; there appears to be a moderate storage volume in the pond to mitigate flood flows to the downstream reach. Downstream of the farm road, the Pond Tributary is badly trampled by cattle, and while an evolutionary trend is difficult to define, this reach will not recover without intervention. The Corn Tributary is generally stable despite being confined in a deep V- shaped valley and impacted by logging debris. Bankfull bench construction and bank sloping are warranted in the short reach at the downstream end to address vertical banks, but the majority of the reach should respond well to debris removal and buffer restoration. The instability over the upstream reach of the Barn Tributary is attributed to the former dam and impoundment. The dam breach is located at the upstream end of a highly incised reach that will continue to erode laterally unless the unstable banks are addressed. At its downstream limit, the Barn Tributary is highly sinuous and suffers from a lack of woody vegetation on the banks, but it is generally stable. The upstream 3,000 LF of the Silage Tributary and both Cow tributaries are actively incising through their steep, V- shaped valleys, with numerous headcuts evident in the profiles. It appears that the incision was set in motion by an increase in runoff from adjacent fields and pastures following initial clearing several decades ago. Landowners indicated that an on -line pond was once present in the Silage Tributary Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 10 channel, but the precise location of the former pond is not known. Removal of the dam and rapid drawdown of the impoundment may have also initiated some headcut erosion. Given the relatively small size of the watersheds, it is likely that these streams were once shorter and the banks much lower than they are now, with hydrology governed by groundwater rather than runoff. It appears that the changing flow regime began the incision and degradation, and buffer deforestation and cattle trampling exacerbated the problems. The upstream end of UT1 exhibits characteristics similar to the Cow tributaries, but the degradation over its downstream reach is less severe. With the exception of the downstream reach of the Silage Tributary, the streams in this drainage are currently G type streams that are unlikely to recover absent intervention. Natural recovery could be expected to hinge on the establishment of volunteer buffer vegetation, but the steam banks and upper slopes appear to lack the geotechnical stability and nutrients necessary for this to happen in the foreseeable future. The downstream 850 LF of the Silage Tributary flows through a flatter and slightly wider valley; here the evolutionary sequence (C to F) is similar to that observed in Moores Fork, with bank erosion and lateral migration ongoing. As with Moores Fork, this lateral migration will likely continue without intervention. The other project streams, UT's 2, 3, 5, 6, 7, 8, 9 and 10, are suitable for preservation by virtue of stable morphology and intact buffers. The reaches of UT4 and UT11 on the property are short and hydrologically disconnected from the remainder of the mitigation areas, and are therefore not included in the project.

Upon completion of site construction, the project components and credits will be revised to be consistent with the as -built conditions. The high end of the credit ratio spectrum for Enhancement Level I was assigned to Moores Fork Reaches 1 and 3 and Barn Tributary Reach 1, where extensive bank shaping, bankfull bench construction, in- stream structure installation and buffer planting are proposed. Similarly, where gully repairs and extensive farm conservation plan improvements are proposed upland of jurisdictional streams and no credit is requested (Cow Tributaries and UT1), we have assigned the high end of the Enhancement Level 11 credit ratio spectrum.

Under no circumstances shall any mitigation project be debited until the necessary US Department of the Army (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 5: Stream Credits Release Schedule Monitoring Year Credit Release Activity Interim Release Total Released 0 Initial Allocation — see requirements above 30% 30% 1 First year monitoring report demonstrates performance standards are being met 10% 40% 2 Second year monitoring report demonstrates performance standards are being met 10% 50% (65 %k ) 3 Third year monitoring report demonstrates performance standards are being met 10% 60% (75 %k ) 4 Fourth year monitoring report demonstrates performance standards are being met 10% 70% (85 %k ) 5 Fifth year monitoring report demonstrates performance standards are being met and project has received closeout approval 15% 100% A reserve of 15% 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. 6.1 Initial Allocation of Released Credits The initial allocation of released credits, as specified in the mitigation plan can be released by the EEP 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 EEP 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. 6.2 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 15% 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 EEP 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 reports. Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 20 7.0 MITIGATION WORK PLAN 7.1 Target Streams The Moores Fork site affords the opportunity to address the major stressors described in the RBRP for the Stewarts Creek watershed. The project design will enhance (and protect where appropriate) the ecological services threatened by these stressors. The proposed conservation easement boundaries will encompass the six wetlands at the site, but no work is proposed and no wetland mitigation credit is being sought. Table 6 below summarizes the links between each design objective proposed for this project and the ecological service improvements that can be achieved on a reach -by -reach basis. Specific site constraints and design measures for each reach, along with the target Rosgen stream types, are presented in Table 7.

In upland areas where stream and floodplain grading are not proposed but where invasive exotic plants have encroached, buffer restoration design will include the following: • Eradication of invasive exotic species; • Preservation of desirable existing species; and • Supplemental planting with selected native trees and shrubs to encourage a more diverse version of the target community. Most of the areas proposed for stream and floodplain grading are currently pasture. The target plant community for these areas will be the same as the upland areas, but species within this community will be Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 23 selected for their adaptation to streambank and floodplain conditions. Appendix C includes a table with several candidate species for buffer planting. 7.3 Design Methodology and Data Analyses The design methodology incorporated both form -based and analytical approaches, using a combination of statistical relationships and analyses to arrive at a design discharge for each reach. Other primary design criteria, such as cross section dimensions, pattern and profile, are all linked to the design discharge and to each other. The following sections summarize each phase of the methodology; supporting calculations and data are included in Appendix C. 7.3.1 Design Discharge In order to estimate a range of design discharges for each reach where dimension and pattern and /or profile modifications are proposed, we evaluated regional regression equations, analyzed field bankfull indicators using hydraulic models, and considered sediment transport competence using critical discharge for initiation of bed material mobility (where sediment data could be obtained). In addition to evaluating discharge at various surveyed riffle cross sections on the project reaches, we also evaluated the predicted discharge for the Mill Creek reference reach as a check of the analysis methodology. As indicated in Table 8, there is considerable spread in the predicted design discharge values. The USGS 2- year estimate typically provides an upper bound on the bankfull discharge while the critical discharge estimates typically provide a lower bound. The critical discharge estimates based on competence appear to under - predict bankfull discharge for all project reaches where suitable samples could be obtained. The regional curve and USGS estimates also appear to under - predict bankfull discharge. Our selected design values are based primarily on the hydraulic models of surveyed cross sections with reliable bankfull indicators, in each case a well- defined bench with evidence of relatively recent flow. The rationale for this decision is that these values are based on site - specific measurements rather than predictions based on average regional conditions or empirical formulae. We checked for possible geomorphic features (scour lines, changes in bank angle, etc.) using the range of predicted discharges and were unable to identify any reliable indicators of the bankfull stage in the surveyed cross sections. The wide spread between predicted and "measured" discharges may be attributable to relatively low infiltration rates, which are possibly influenced by soil compaction in pastures, shallow bedrock and steep upland areas throughout the Moores Fork watershed.

We did not perform hydraulic or sediment transport analyses for reaches where pattern or profile are not proposed to be changed. Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 24 The smaller project reaches (Silage, Pond, Barn and Corn Tributaries) were either so heavily impacted by cattle or small enough in cross section to make pebble counts infeasible. In order to gather some sediment size data for these streams, representative bar samples were collected and analyzed; the Pond Tributary is so heavily trampled that even bar sampling was not feasible. 7.3.2 Sediment Transport As part of our sediment transport evaluations, we considered landscape position and the connections between the various reaches, with a focus on Moores Fork. A qualitative assessment of Moores Fork at the project site and the reach upstream reveals the following general conditions: • The reach immediately upstream is a both a source of sediment to the project reaches (through hillslope and bank erosion processes) and a transport reach. Sediment export appears to be balanced with supply; the reach has a bedrock controlled profile, a steep, rocky hillside on the right bank and exposed, unstable soils on the left bank. • Reach 1 is primarily a transport reach, similar in profile to the upstream reach with somewhat more prominent bars, some of which are influenced by in- stream woody debris. • Reach 2 is primarily a storage reach, but extensive bank erosion provides a source of fine sediment to the system. Lateral erosion has allowed large mid - channel and lateral bars to form. • Reach 3 has storage, source and transport sub - reaches, with several large bars (storage), widespread bank erosion and hillslope colluvium (source) and bedrock controlled bed and banks (transport). Given the presence of mid - channel sediment deposition and abundant bedrock in the bed, aggradation is more of a concern that degradation for Moores Fork. Our Moores Fork sediment transport analyses were targeted on developing design strategies to accommodate excess sediment supply Table 8 above summarizes sediment transport competence analyses; supporting data are included in Appendix C. Our analyses indicate the design streams (in terms of cross section and profile) will transport the size of the large bed materials sampled at the site. We also evaluated sediment transport capacity and continuity between the supply and design reaches, using unit stream power as the indicator parameter. We compared stream power over a range of stages up to and above the bankfull stage to check if continuity was achieved. Hydraulic models (HEC -RAS and RIVERMorph) of the existing and design conditions were used to support the sediment transport analyses by providing hydraulic parameters such as hydraulic radius, slope, shear stress, and power. Graphical output of these analyses is included in Appendix C. Analyses indicate that the unit stream power in the Moores Fork design reaches is somewhat lower than the supply reach, but slightly greater than the existing conditions up to the bankfull stage. The decrease in sediment transport capacity from the supply reach to the project reaches suggests that excess sediment may continue to deposit in the project reaches. The design cross section shape and size accounts for this potential by providing space for sediment deposition in advantageous sections of the channel, such as in point bars. In- stream structures will also be used to reduce the potential for mid - channel deposition in riffles and runs. We expect that sediment loads and the potential for excessive mid - channel deposition will be reduced significantly once upstream banks on the site are stabilized. At the Silage Tributary, sediment supply is low and velocities are high, so the main concern in the steep Reach 1 is down - cutting and the key parameter is boundary shear. Comparisons of existing versus design boundary shear for Reach 1 indicate reductions in the design shear at the bankfull stage. At twice the bankfull stage and beyond when valley morphology dictates hydraulic behavior, the design shear is slightly higher than the existing shear, but not enough of a difference to warrant design adjustments. The flatter Silage Tributary Reach 2 and the Pond Tributary are similar to Moores Fork in terms of morphology, and bank erosion and deposition are the main concerns. For both of these reaches, the estimated shear and unit stream power values are similar to the existing cases up to the bankfull stage. Above the bankfull stage, the design values are less than the existing up to about 2.5 times the bankfull stage, at which valley morphology governs the hydraulics. Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 25 The primary design goal for proposed enhancement reach of the Barn Tributary is to provide floodplain access in order to reduce shear on the badly incised banks. Analyses indicate an abrupt decrease in shear at the bankfull stage. The estimated shear increases approaches the reference case at stages of about 2 times bankfull, where valley morphology comes into play. 7.3.3 Cross Section Design discharge and sediment transport analyses inform the design of cross section dimensions and shapes; cross section dimensions and shapes along with slope govern hydraulic parameters that are relevant to design. Past experience also informs the cross section design. For example, project monitoring over the past several years has indicated that a newly constructed E or C -type channel with a width -depth ratio less than about 10 can lead to stability problems. We evaluated reference cross sections (on Moores Fork and the Corn and Barn Tributaries) as indications of bankfull area and general shape, but the design bank slopes are also governed by geotechnical stability needs during the monitoring period in areas where little or no deep- rooted vegetation will be present for the first few growing seasons. Ratios of pool -to -riffle depth and top width are based in part on reference reach data and in part on past experience. Relative to hydraulic geometry relationships and sediment transport competence modeling, the design discharges (and therefore cross section dimensions) are on the large side for each of the project reaches. As noted in the previous section, the design cross sections will accommodate sediment storage within the channel on point bars and /or in lateral bars upstream of vane structures. This stored sediment is available for transport during large flow events, which promotes long -term stability and sediment transport equilibrium. 7.3.4 Plan and Profile Plan geometry design is based on multiple factors, chiefly the selected design slope and lateral constraints such as easement boundaries and topography. At a particular plan feature such as a meander bend, geometry is based on a range of dimensionless ratios that have proven to be effective in meeting design objectives while promoting stability. The prime example for plan geometry is radius of curvature ratio; well- vegetated reference reaches (Mill Creek for example) suggest a radius of curvature ratio of 1.0 or less would be desirable, but experience indicates that a ratio less than about 1.8 places undue stresses on newly constructed banks that lack deep rooted vegetation. Reference cross section /reach data are summarized in Appendix C. We considered reference reaches when developing plan geometry. Our search for a Moores Fork reference reach included upstream reaches of Moores itself and several other streams in relatively undisturbed watersheds, primarily in Surry County. We identified a reach of Mill Creek with a stable meander bend in a valley and with bed materials similar to those found in Moores Fork. As with reference cross sections, reference plan form is useful as a general guide for parameters such as belt width, radius of curvature and pool -pool spacing. However, as with low width -depth ratios in reference cross sections, tight radii and pool spacing in reference reaches often cannot be assigned to a design reach without risk of stability problems in the time while vegetation is becoming established. The selected pattern and profile take into account aquatic habitat needs, stability throughout the monitoring period and space constraints. With pattern being directly linked to profile, we considered profile constraints such as existing bedrock outcrops as well as sediment transport equilibrium when assigning profile grades. The target stream type for Moores Fork is a moderately sinuous, moderate width -depth ratio C4, which is appropriate for the relatively flat and wide alluvial valley through which it will flow. Reaches 1 and 3 will be constructed largely within the existing channel, with modest pattern shifts where existing pattern is unstable. In- stream structures will be incorporated in both of these reaches to promote sediment transport equilibrium, riffle and pool formation, and enhanced bank stability. Reach 2 will be constructed Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 26 mainly off -line to position the channel in the low point of the valley and provide better floodplain access on both banks. The overall approach can be described as a hybrid Rosgen Priority 2/3 restoration. Given its slope and confined valley, the stable morphology for Reach 1 of the Silage Tributary is a step - pool, B4 stream type. For key profile design parameters such as step height, pool width and depth and pool spacing, we consulted the research of Chin and Abrahams, Li and Atkinson. We established the design profile based on the ratio of step height to step length, which was found in stable natural step pool systems to vary from 1 to 2. For practical purposes based on available stone and log sizes, the step height was capped at 16 inches. Because of the highly confined nature of the Silage Tributary and the desire to preserve mature upland trees, addressing eroding banks and incised conditions through bank sloping is not practical. The design solution is to partially fill the channel (3 to 4 feet deep) with clayey soil (compacted in horizontal lifts not exceeding 9 inches in thickness) and create a new channel cross section and step pool profile at a higher elevation. Vegetated upland areas will be protected. The new bed will be reinforced with stone riffles, sized to resist mobilization at flows beyond bankfull. For the purposes of this mitigation plan we are assuming no loss of stream length. Reach 2 of the Silage Tributary, the Corn Tributary and the Barn Tributary are similar in terms of morphology; each is a relatively steep alluvial channel with significant incision and bank erosion problems with little length to transition to a stable profile end point. The design approaches for these streams are also similar. The channels will be left in their current alignments, banks will be graded to stable slopes, bankfull benches will be constructed and in- stream structures will be used to promote bed and bank stability. Reference cross sections on stable reaches of the Corn and Barn Tributaries were used to size the design cross sections for these streams. The target stream type for the Pond Tributary is a moderately sinuous, moderate width -depth ratio C4. The project reach begins at the outlet of the culvert where flow drops about 2 feet to a small plunge pool at the existing thalweg. The design profile will start at this existing thalweg elevation, taking advantage of the energy dissipating effects of the pool, and then abandon the badly trampled channel for a new alignment across the floodplain to the east. The downstream end of the profile includes a 1.5 -foot high transition to the Moores Fork thalweg, which will be constructed using a grade control structure. Both of the Cow Tributaries will be stabilized in their current channels, using grade control structures in select locations to address headcut erosion. These reaches are badly trampled by cattle and should respond well to livestock exclusion, both in terms of morphology and buffer vegetation. The design includes filling and stabilizing gullies at the headwaters of the Silage Tributary, the Cow 1 and Cow 2 Tributaries, UT1 and two runoff conveyances entering Moores Fork Reach 3. The proposed gully stabilization will include upland measures such as level spreaders, swales and vegetation to divert and /or redirect concentrated runoff away from gullies. Check dams made from riprap, woody brush, crushed concrete, decay resistant logs and other on -site materials will be used to reduce erosive stresses in the gullies and promote long -term healing. Stabilized areas will be planted with species and densities as specified for buffer areas. 7.3.5 In- Stream Structures In- stream structure types and locations were selected based on design stability, habitat enhancement and sediment transport objectives within each reach. Table 9 below provides a summary of specific objectives for the proposed structures. Data and analyses supporting the sizing of stone for in- stream structures are provided in Appendix C.

Routine vegetation maintenance and repair activities may include supplemental Vegetation 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.

Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 29 9.0 PERFORMANCE STANDARDS In accordance with the provisions in CFR Title 33, "performance standards that will be used to assess whether the project is achieving its objectives... and should relate to the objectives ... so that the project can be objectively evaluated to determine if it is developing into the desired resource type, providing the expected functions, and attaining any other applicable metrics ". Table 11 below lists proposed success criteria for each proposed ecological service enhancement. While some success criteria are quantitative (e.g. bank height ratio) and others are qualitative (e.g. observations of fine sediment deposition on the floodplain), each is measurable. Year to year comparisons for the various parameters will allow adaptive management to be implemented early on in the monitoring period if necessary in order to reduce the risk of widespread problems. Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 30 Table 11. Performance Standards Proposed Ecological Service Metrics /Success Criteria Enhancements a.

The monitoring report shall provide a project data chronology that will facilitate an understanding of project status and trends, population of EEP databases for analysis, research purposes, and assist in decision making regarding project close -out. Table 12. Monitoring Requirements Required Parameter Quantity Frequency Notes As per April 2003 USACE Pattern /profile survey will extend for at least Pattern Wilmington District Stream annual 20 bankfull widths per reach.

This party shall be responsible for periodic inspection of the site to ensure that restrictions required in the conservation easement or the deed restriction document(s) are upheld. Endowment funds required to uphold easement and deed restrictions shall be negotiated prior to site transfer to the responsible party. The NCDENR Division of Natural Resource Planning and Conservation's Stewardship Program currently houses EEP stewardship endowments within the non - reverting, interest - bearing Conservation Lands Stewardship Endowment Account. The use of funds from the Endowment Account is governed by North Carolina General Statute GS 113A- 232(d) (3). Interest gained by the endowment fund may be used only for the purpose of stewardship, monitoring, stewardship administration, and land transaction costs, if applicable. The NCDENR Stewardship Program intends to manage the account as a non - wasting endowment. Only interest generated from the endowment funds will be used to steward the Moores Fork Stream Mitigation Project - Draft Final Mitigation Plan March 2012 31 compensatory mitigation sites. Interest funds not used for those purposes will be re- invested in the Endowment Account to offset losses due to inflation. 12.0 ADAPTIVE MANAGEMENT PLAN Upon completion of site construction EEP will implement the post- construction monitoring protocols previously defined in this document. Project maintenance will be performed as described previously in this document. If, during the course of annual monitoring it is determined the site's ability to achieve site performance standards are jeopardized, EEP will notify the USACE of the need to develop a Plan of Corrective Action. The Plan of Corrective Action may be prepared using in -house technical staff or may require engineering and consulting services. Once the Corrective Action Plan is prepared and finalized EEP will: 1. Notify the USACE as required by the Nationwide 27 permit general conditions. 2. Revise performance standards, maintenance requirements, and monitoring requirements as necessary and /or required by the USACE. 3. Obtain other permits as necessary. 4. Implement the Corrective Action Plan. 5. Provide the USACE a Record Drawing of Corrective Actions. This document shall depict the extent and nature of the work performed. 13.0 FINANCIAL ASSURANCES Pursuant to Section IV H and Appendix III of the Ecosystem Enhancement Program's In -Lieu Fee Instrument dated July 28, 2010, the North Carolina Department of Environment and Natural Resources has provided the U.S. Army Corps of Engineers Wilmington District with a formal commitment to fund projects to satisfy mitigation requirements assumed by EEP. This commitment provides financial assurance for all mitigation projects implemented by the program. 14.0 DEFINITIONS DX— with respect to sediment grain size distribution, the grain mean diameter which is larger than x% of the sample distribution Morphological description — the stream type; stream type is determined by quantifying channel entrenchment, dimension, pattern, profile, and boundary materials; as described in Rosgen, D. (1996), Applied River Morphology, 2nd edition Native vegetation community — a distinct and reoccurring assemblage of populations of plants, animals, bacteria and fungi naturally associated with each other and their population; as described in Schafale, M.P. and Weakley, A. S. (1990), Classification of the Natural Communities of North Carolina, Third Approximation Project Area - includes all protected lands associated with the mitigation project Priority Levels of Restoration — 1: convert incised stream to new stream at original floodplain elevation; 2: establish new stream and floodplain at existing stream elevation; 3: convert incised stream to new stream type without establishing an active floodplain but providing flood -prone area; 4: stabilize incised stream in place.

Mobilize equipment and materials to the site. Locate limits of disturbance. 2. Establish construction entrances /exits and staging areas as shown on the plans. Access to the site will be via Horton Road and existing farm paths. Existing stream crossings (culverts and bridge) shall be used during construction. Install additional temporary stream crossings on Moores Fork as needed to access work areas. 3. Establish construction haul routes using existing farm paths to the extent feasible. Minimize disturbance beyond immediate haul routes and grading limits. Stabilize haul route surfaces with stone and filter fabric as necessary. 4. Hardwood trees 12 inches dbh and larger that require removal per the plans shall be salvaged for on-site use as in- stream structures. Attention shall be paid to the specified trunk lengths of log and root wad structures shown on the plans. 5. The stems and root masses of exotic invasive species (multi flora rose, Chinese privet, etc.) generated during grading operations shall be bufned on site or disposed in approved off site locations. 6. Any stockpiled materials not used for backfill within 30 days of excavation shall be stabilized with temporary seed and straw mulch Phase 2: Off -Line Channel Construction 1. Perform sod mat cutting within grading limits and stockpile separate from backfill soil for later use on stream banks and planting areas. Limit stripping to those areas that will be graded within 3 days to minimize softening and degradation of subgrade soils under construction traffic. 2. When excavating new offline channel, lea%eplugs of existing bank material in place atupstream and downstream ends. Base flow shall be maintained in the existing channel until new channel is fully stabilized with sod mats, seeding and structures riffles 3. Complete in- stream structure installation and bank stabilization on the new channel. Transplant sod mats. Seed and mat banks where sod mat transplanting is not feasible. Stockpile excavated soils between new channel and existing channel for later backfilling. Silt fence shall be installed on the creek side of all stockpiles. 4. Working from the top of the existing stream banks, excavate gravel and cobble bar sediment and stockpile separately for use in constructed riffles and otherstructures 5. Once the new channel is stabilized, complete tie ins from existing to new channel, taking precautions to limit introduction of soil to live stream. Diverting water into the new channel shall proceed according to the following steps a. Remove plug at downstream end of new off -line channel b. Setup pump- around operation above upstream tie -in. c. Grade online stream channel to proper dimensions and profile and tie -in to new offline channel. d. Backfill abandoned channel upstream to downstream, using stockpiled soil, compacted in lifts not to exceed 12 inches in thickness. Stabilize with straw mulch, temporary and permanent seed. Phase 3: On -Line Channel Construction 1. Base flow shall be diverted per the plans using a single diversion setup if feasible. Install temporary sandbag cofferdams upstream and downstream of work area. Install pump, suction and discharge lines, and divert flow around tie -in area. Install dewatering pump as necessary and discharge through silt bag. 2. Perform earthwork, in- stream structure installation, geo- lifts, seeding, mulching and matting per the plans.
