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.pdf) 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 Restoration 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 1,828 LF of Moores Fork and 243 LF of one UT; • Restoration of the dimension and profile (Enhancement 1) of the channel for approximately 2,832 LF of Moores Fork and 3,710 LF of three UTs; • Limited channel work coupled with livestock exclusion, gully stabilization, invasive species control and buffer planting (Enhancement 11) on approximately 761 LF of Moores Fork and 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 Restoration Project- Draft Final Mitigation Plan July 2012 1 20 SITE SELECTION 21 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 22 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 Restoration Project - Draft Final Mitigation Plan July 2012 2 As Shown Moores Fork Restoration Figure 1: Site Vicinity Map Surry County, NC Moores Fork Stream Restoration Project - Draft Final Mitigation Plan July 2012 Moores Fork Stream Restoration Project - Draft Final Mitigation Plan July 2012 ZS 1` 1 _ — r- 0 D bmY CrCd / 'roc _ `�, � •,�� � /iyf V ~L` � JJ.

watershed with the TLW (EcoEngineenng 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 bams 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 Bam 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 Bam 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 com 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 Bam Tributary drainage are also impacted Table 1 summarizes stressors and ecological services needing enhancement in the project area Table 1 Stressom and Proposed Ecological Service Enhancements Stressor Ecological Services Needing Enhancement Channel incision Flood attenuation fine sediment storage maintenance of stable channel bed and banks Bank erosion and mid- channel sediment deposition Equilibrium sediment transport maintenance of in- stream riffle and pool habitats Buffer deforestation Filtration of runoff thermal regulation input of organic matter Invasive, exotic vegetation Riparian buffer habitat, species diversity Direct livestock access to streams Protection of water quality from nutrient inputs Moores Fork Stream Restoration Project - Draft Final Mitigation Plan July 2012 9 24 Evolutionary Trends Appendix C Includes a two-page Inventory map showing areas of significant bank erosion bar formation gully formation and debris dams 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 bonngs 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 Restoration Project - Draft Final Mitigation Plan July 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 tnbutaries 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 Moores Fork Stream Restoration 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 Reach 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 II credit ratio spectrum. Descriptions of each reach with proposed treatments are presented Table 4a below. Table 4a.

Impacted by vegetation removal and encroachment of invasive species; gully incision and bank erosion; some matures trees on both banks and upland areas. UT1 Uplift gained by on -line enhancements including, invasive species removal, buffer planting and upland gully stabilization /runoff management. Livestock fencing will be installed. Buffers generally intact and channel bed and banks in stable forms. Buffer vegetation includes a mix of hardwoods and woody shrubs. Potential encroachment from adjacent fields and pastures threatens to degrade the quality of these streams. Preservation Reaches UTs 2,3,5,6,7,8,9, 10 Uplift gained by protection of intact buffers and streams with conservation easements that extend well beyond the minimum 50 -foot top of bank offsets. In several areas, buffer widths exceed 200 feet. Livestock fencing will be installed in areas where pastures are adjacent to easement boundaries. The farm management plan will improve water quality in upland areas by relocating feed lots and silage pits away from surface waters.

Draft Final Mitigation Plan July 2012 25 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 selected for their adaptation to streambank and floodplain conditions Appendix C includes a table with several candidate species for buffer planting 73 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 are at the low end of the range for all project reaches where suitable samples could be obtained The regional curve and USGS estimates are also at the low end of the discharge range Our selected design values are based primarily on hydraulic models that include surveyed cross sections with reliable bankfull indicators in each case a well- defined bench with evidence of relatively recent flow The reach -wide model which also accounts for floodplain and channel roughness allowed us to adjust discharge until the stage matched the stable bankfull indicators We also used the model to check for other 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 other than those that were first identified in the field We are confident in the modeled discharges because they are based on site - specific measurements rather than predictions based on average regional conditions or empirical formulae Also as discussed in Section 7 3 2 the design attempts to create sediment transport continuity with upstream supply reaches so as to address widespread mid - channel deposition as is evident throughout Moores Fork The reach of Moores Fork immediately upstream of the project limits has greater transport capacity than the project reach owing mainly to a 40 percent greater slope The existing stable cross sections (M1 1 M1 6 M1 7 M1 9 and M1 10) appear to have adjusted shape and dimension to be in better balance with the supply reach than the unstable cross sections likely because of more robust bank vegetation and more frequent floodplain access Our analysis of a design discharge based on regional relationships or critical discharge estimates indicates that such a design would lead to even more sediment transport imbalance than currently exists because the resulting smaller cross section would have less competence and capacity We have considered contributing factors to explain the wide spread between predicted and measured" discharges We also surveyed additional cross sections and profiles near the upstream limits of Moores Fork and these surveys confirm our measurements and predictions in the supply reach and project reaches Our observations in the Moores Fork watershed indicate that the differences are likely attributable to relatively low infiltration rates caused by sod compaction in pastures shallow bedrock steep upland areas and impervious surfaces along the Interstate 77 corridor Moores Fork Stream Restoration Project -

reaches with several large bars (storage) widespread bank erosion and hlllslope 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 Moores Fork Stream Restoration Project — Draft Final Mitigation Plan July 2012 27 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 Slope and cross section size and shape are the factors that determine stream power There is no realistic opportunity to increase slope in the project reaches to match the supply reach slope so cross section shape and size become the design focus As discussed in Section 7 3 3 there are geotechnlcal stability considerations for cross section design the design attempts to optimize sediment transport continuity and bank stability Analyses indicate that the design unit stream power in the Moores Fork restoration and enhancement reaches is somewhat lower than the supply reach but 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 vane 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 once upstream banks on the site are stabilized but off -site reaches will likely continue to deliver a relatively large supply of sediment 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 The primary design goal for proposed enhancement reach of the Barn Tributary is to provide floodplaln 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 Com 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-nffle depth and top width are based in part on reference reach data and in part on past experience 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 Mobilized sediment in the project reaches will be replaced by sediment from upstream Moores Fork Stream Restoration Protect - Draft Final Mitigation Plan July 2012 28 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 MITI 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 mainly off -line to position the channel In the low point of the valley and provide better floodplaln 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 64 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 In order to limit the potential for excess shear stress on the structures and surrounding bed and banks the step height was capped at 12 Inches Where fish passage Is a consideration (not the case for the Silage Tributary because there does not appear to be a fish population present), step heights will be limited to 6 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 Com 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 Com 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 Moores Fork Stream Restoration Project -

stream locations 11 0 LONG -TERM MANAGEMENT PLAN Upon approval for close -out by the Interagency Review Team (IRT) the site will be transferred to the NCDENR Division of Natural Resource Planning and Conservation s Stewardship Program This party shall be responsible for periodic inspection of the site to ensure that restrictions required in the conservation easement or the deed restnction document(s) are upheld Endowment funds required to uphold easement and deed restrictions shall be negotiated pnor 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 govemed by North Carolina General Statute GS 113A- 232(d) (3) Interest gained by the endowment fund maybe 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 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 dunng 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 monitonng 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 Programs 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 Moores Fork Stream Restoration Project— Draft Final Mitigation Plan July 2012 33 14 0 DEFINITIONS D,— 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, 2"d 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 -

rlsQ�e�ul CONSTRUCTION SEQUENCE OF EVENTS Phase 1 Mobilization and General Site Preparation 1 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 burned on site or disposed in approved off site locations 6 Any stockpiled materials not used for backfdl within 30 days of excavation shall be stabilized with temporary seed and straw mulch Phase 2 Off -Une Channel Construction 1 Perform sod mat cutting within grading limits and stockpile separate from backfill sod 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 offlme 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 sods between new channel and existing channel for later backfiilling 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 other structures 5 Once thenew 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 offhne 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 sand bag coffer dams upstream and downstream of work area Install pump suction and discharge lines and divert flow around tie in area Install dewatenng pump as necessary and discharge through silt bag 2 Perform earthwork in stream structure installation geo Gifts seeding mulching and matting per the plans Salvage gravel and cobble sediment for use in constructed riffles and other structures 2 Permanently dispose of excavated material in approved upland or off site area Silt fence shall be installed on the creek side of all temporary stockpiles 3 Temporarily dismantle flow diversion prior to flood event that exceeds capacity of diversion ensuring that work areas are fully stabilized 4 Once restored channel is fully stabilized dismantle pumps discharge lines and coffer dams and return flow to restored channel Phase 4 Demobilization 1 Upon completion of stream and floociplam grading operations silt fences shall be removed construction entrances /exits shall be removed and the construction haul routes shall be graded seeded and mulched as needed to restore them to their pre project conditions 2 Upon demobilization of equipment and materials the staging areas shall be restored to their pre project conditions Phase 4a Planting 1 Site planting including live stakes and bare root trees and shrubs shall be completed after grading and in-stream structure operations are complete and during the dormant season (November to April)
