Project Description ]a. Property identification no. (tax PIN or parcel ID): See attached above table -Owner Information Page 1 of 6 Supplemental Information for Pre - Construction Notification (PCN) Form Muddy Run II Stream and Wetland Mitigation Project B. Project Information and Prior Project History 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The Muddy Run II Stream and Wetland Mitigation Project is located within an agricultural watershed in Duplin County, North Carolina, approximately 6 miles south of Beulaville (Figure 1). This project lies within USGS Hydrologic Unit Code 03030007060010 (USGS, 1998) and within the North Carolina Division of Water Quality (NCDWQ) Cape Fear River Subbasin 03 -06 -22 (NCDENR, 2002). The Muddy Run II project consists of six unnamed tributaries to Muddy Creek, but the project has been divided into nine distinct reaches for design purposes. Reach 1 is one of the upstream -most portions of the project; it begins on the edge of an existing agricultural field and extends to STA 04 +45. Similarly, Reach 2 is one of the upper -most portions of the stream project. It begins in a disturbed forest corridor between several agricultural fields and extends to STA 18 +73. Reach 3a -I starts at the confluence of Reaches I and 2 (STA 00 +00) and flows north north -west for 730 linear feet. Reach 3a -2 flows through a disturbed hardwood buffer and several agricultural fields before being partially diverted to enter Reach 3b near STA 37 +36. Reach 3b flows to the north and west where it flows into Reach 3c at STA 56 +78. Reach 3c flows through a pine plantation to STA 64 +15, where it flows into Reach 3 of the Muddy Run project. Reach 4 is a perennial channel that flows through a forested area from a ditch draining an agricultural field. Reach 4 flows into Reach 3 A at STA 18 +36. Reach 5a consists of the main stem beginning at STA 00 +00 where it adjoins with Reach IC of the Muddy Run project. Reach 5a flows north and flows into Reach 5b at STA 18 +04. Reach 5b is the most downstream reach of the project, ending at the right -of -way for State Highway 41. Reach 6 begins in a forested area south of Reach 5 and flows in a northerly direction to the confluence with Reach 5a near STA 8 +70. Two areas containing drained hydric soil were identified for restoration, located along Reach 3b and Reach 5a. The site consists of farmland, concentrated animal feeding operations (CAFO), and wooded areas. The total easement area is 37.6 5acres, 20.6 acres of which are wooded. The remaining area is agricultural or clear -cut. The wooded areas along the corridor designated for restoration are classified as disturbed deciduous forest, and invasive species are prevalent throughout. Several ditches exist throughout the project and flow into the main channel. Each ditch contributes to the overall design discharge of the channel. All existing channels are degraded to a point where they no longer access their floodplain, water quality is poor, and aquatic life is not supported. Little habitat is available to support aquatic life, and the channels are not maximizing their potential to filter nutrients because they are entrenched. 3d. Explain the purpose of the proposed project: The purpose of the Muddy Run II Mitigation project is to restore wetland areas and design a natural waterway through a stream/wetland complex with appropriate cross - sectional dimension and slope that will provide function and meet the appropriate success criteria for the existing streams. Accomplishing this objective entails the restoration of natural stream characteristics, such as stable cross sections, planform, and in -stream habitat. The floodplain areas will be hydrologically reconnected to the channel to provide natural exchange and storage during flooding events. The design will be based on reference conditions, USACE guidance ( USACE, 2005), and criteria that are developed during this project to achieve success. Additional project objectives, such as restoring the riparian buffer with native vegetation, ensuring hydraulic stability, and eradicating invasive species, are listed in Section I along with several other project objectives. Page 2 of 6 Supplemental Information for Pre - Construction Notification (PCN) Form Muddy Run II Stream and Wetland Mitigation Project B. Project Information and Prior Project History 3e. Describe the overall project in detail, including the type of equipment to be used: Natural channel design techniques have been used to develop the restoration designs described in this document. The combination of the analog and reference reach design methods were determined to be appropriate for this project because the watershed is rural, the causes of disturbance are known and have been abated, and there are minimal infrastructure constraints. The original design parameters were developed from the measured analog /reference reach data and applied to the subject stream. The parameters were then analyzed and adjusted through an iterative process using analytical tools and numerical simulations of fluvial processes. The designs presented in this report provide for the restoration of natural Coastal Plain sand -bed channel features and stream bed diversity to improve benthic habitat. The proposed design will allow flows that exceed the design bankfull stage to spread out over the floodplain, restoring a portion of the hydrology for the existing wetlands. A large portion of the existing stream will be filled using material excavated from the restoration channel and from a large spoil area adjacent to the western hog lagoons. However, many segments will be left partially filled to provide habitat diversity and flood storage. Native woody material will be installed throughout the restored reach to reduce bank stress, provide grade control, and increase habitat diversity. Forested riparian buffers will be established along the project reaches to have widths of at least fifty feet on both sides of the channel. An appropriate riparian plant community will be established to develop multiple strata and a diverse mix of species. Any existing buffer areas impacted during construction will be replanted with native species. Wetland restoration will occur adjacent to stream Reaches 3a -2 and 5a. The approach is to reconnect the floodplain wetland to the stream fill ditches, create shallow pool habitat, rough the floodplain surface, and plant appropriate small stream swamp vegetation. C. Proposed Impacts Inventory 2h. Comments: (Wetland Impacts) A wetland delineation was performed in November 2011 utilizing the Routine On -site Determination Method ( USACE, 1987). A jurisdictional determination of the wetlands has not been made by the US Army Corps of Engineers ( USACE), but the USACE has visited the restoration site. The wetland delineation is mapped on the Current Conditions Figure (Figure 4). Onsite wetlands include riparian wetlands along Reach 3a/Reach 4 and both sides of Reach 3b. Wetland I is located along Reach 3a on the right bank. The current land use is forested along the dredged channel just downstream of Reach 4, which divides this wetland. This wetland is seasonally saturated. Hydrology is primarily runoff that collects within a shallow depression and restricted by berms along the dredged channels. This wetland is 0.29 acres. Wetland 2 is located along Reach 3b on both sides of the channel. The current land use is mature forest. The stream through this wetland is diverted from its historic flow pattern to promote drainage for agricultural production. This wetland is seasonally saturated. Hydrology is currently due to its lower landscape position collecting runoff. Large flood events likely inundate this wetland on a limited basis. This area may also experience limited groundwater discharge. This wetland is 2.23 acres. Wetland impacts associated with restoration efforts occurring adjacent to the existing wetlands (Wetlands 1, and 2) along Reaches 3a and 3b will be minimized by the restoration plan. Creating a new stream channel that will only impact them slightly will provide an overall increase in wetland function with the addition of native trees and shrubs along the stream banks. Construction in these areas will also remove the invasive species in connection with the building of the new channel. Two additional wetland restoration areas are located on the Muddy Run II Mitigation project. These areas will total 4.92 acres of wetland restoration.

Total stream and tributary impacts 10,314 3i. Comments: (Stream Impacts) Reach 1 has a drainage area of 0.11 square miles (68 acres), and flows in a northerly direction adjacent to a cultivated field. Reach 1 is one of three proposed headwater valley restoration reaches totaling 401 linear feet. The planform of this G -type channel is generally straight and is entrenched throughout. The current cross sectional area is 41.9 square feet with approximate dimensions of 14.7 feet wide and 2.9 feet deep. The existing length of Reach 1 is 438 linear feet, and the dominant bed material is fine sand. The gradient of the reach is approximately 0.0043 It/ft. The reach is severely oversized and exhibits moderately unstable banks. The riparian buffer is forested along the east bank and a sparse along the west. Reach 2 is an oversized intermittent channel located in a disturbed, forested corridor. Reach 2 is approximately Page 4 of 6 Supplemental Information for Pre - Construction Notification (PCN) Form Muddy Run II Stream and Wetland Mitigation Project 1,727 linear feet, and flows west to its confluence with Reach 1. It has a drainage area of 0.18 square miles (114 acres). Reach 2, an F -type channel, is typically 16.2 feet wide and 2.5 feet deep. Spoil piles are located adjacent to the channel, a result of past dredging. This indicates that during channelization, the stream was dug exceedingly deep to aid in draining the adjacent fields. The average cross sectional area is approximately 41.2 square feet. The existing slope of Reach 2 is 0.0021 ft/ft, and the dominant bed material is fine sand. Reach 3a -1 begins at the confluence of Reaches 1 and 2 and flows northwest and ends at approximate STA 8 +31. Reach 3a -1 has a drainage area of 0.36 square miles (227 acres) and has a width and depth of 15.4 feet and 1.4 feet, respectively. The existing cross - sectional area is approximately 22.2 square feet. The existing slope is 0. 00 16 ft/ft and has little to no buffer on either side of the channel. This reach is classified as a F5 stream type and has an existing length of 831 linear feet. Reach 3a -1 is an incised, excavated, perennial channel with a disturbed hardwood buffer. The banks are moderately unstable and lack mature hardwood vegetation. Approximately 730 linear feet of Priority 1 restoration is proposed on Reach 3a -1. Reach 3a -2 is very similar to Reach3a -1 in morphological parameters and existing conditions. Reach 3a -2 begins at Sta. 9 +96 and runs to 37 +36. Approximately 2,710 linear feet of Priority 1 restoration is proposed along Reach 3a- 2. This stream reach has an existing length of 2,470 linear feet. Two stream crossings are proposed along Reach 3a- 2 as well as Wetland Restoration area WA. Reach 3b was diverted from its historic flow pattern to promote drainage for agricultural production. The reach currently flows to the north and east across a natural divide (Ludie Brown Road) and into an unnamed tributary of Muddy Creek. LiDAR mapping, historic aerial photography, landowner interviews, and on -site survey confirm the historic flow pattern was to the west and eventually flowed into the Muddy Run I project. The proposed alignment for Reach 3b begins behind a CAFO (existing STA 33 +75), and flows southwest where it follows along a relic flow path to Reach 3c (STA 47 +78). Reach 3b has a proposed drainage area of 0.52 square miles (333 acres), and the relic channel features exhibit a width and depth of 5.6 feet and 0.7 feet, respectively. The existing cross - sectional area is approximately 2.5 square feet with a slope of 0.0023 ft/ft. The riparian buffer is well - established with a mix of pines and hardwoods. This reach is classified as a C5 stream type and has an existing length of 464 linear feet. Reach 3c is an incised but stable channel through a pine plantation with a mature hardwood component on the channel banks and top of bank. The channel is stable and mendering within its banks. Reach 3c is approximately 737 linear feet, and flows south to the Muddy Run Site. It has a drainage area of 0.58 square miles (370 acres). Reach 3c, an F -type channel, is typically 16.7 feet wide and 2.2 feet deep. The average cross sectional area is approximately 36.5 square feet. The existing slope of Reach 3c is 0.0022 ft/ft, and the dominant bed material is fine sand. Reach 4 is a small, stable, perennial channel. The channel was likely dredged and straightened historically, but is stable and slightly oversized. The buffer and channel banks include mature hardwood vegetation. Reach 4 is approximately 120 linear feet, and flows southwest to Reach 3a. It has a drainage area of 0.07 square miles (46 acres). Reach 4, a G -type channel, is typically 11.0 feet wide and 1.6 feet deep. The average cross sectional area is approximately 17.0 square feet. The existing slope of Reach 4 is 0.0034 ft/ft, and the dominant bed material is fine sand. Reach 5a is an oversized perennial channel. Banks are moderately unstable and bedform diversity is low. Bank vegetation to the south includes some hardwoods and invasive species, while the buffer to the north is an active agricultual field. Reach 5a is approximately 1,602 linear feet, and flows northwest to Reach 5b. It has a drainage area of 1.21 square miles (774 acres). Reach 5a, a G -type channel, is typically 18.4 feet wide and 2.6 feet deep. The average cross sectional area is approximately 47.8 square feet. The existing slope of Reach 5a is 0.0024 ft/ft, and the dominant bed material is fine sand. Reach 5b is the downstream -most reach on Muddy Run II, and also conveys all flow from the Muddy Run project. This perennial channel is incised, and has moderately unstable banks. The active channel is meandering within the oversized, dredged channel. Reach 5b is approximately 401 linear feet, and flows northwest to Highway 41. It has a drainage area of 1.42 square miles (908 acres). Reach 5b, a G -type channel, is typically 17.0 feet wide and 2.9 feet deep. The average cross sectional area is approximately 49.3 square feet. The existing slope of Reach 5b is 0.0015 Page 5 of 6 Supplemental Information for Pre - Construction Notification (PCN) Form Muddy Run II Stream and Wetland Mitigation Project ft/ft, and the dominant bed material is fine sand. Reach 6 is a greatly oversized intermittent channel located within a forested corridor. Reach 6 is approximately 317 linear feet, flows north to its confluence with Reach 5a, and has a drainage area of 0.12 square miles (77 acres). Reach 6, a G -type channel, is typically 13.0 feet wide and 3.2 feet deep. Spoil piles are located adjacent to the channel along both banks, a result of past dredging. This indicates that during channelization, the stream was dug exceedingly deep to aid in draining the adjacent agricultural land. The average cross sectional area is approximately 42.3 square feet. The existing slope of Reach 6 is 0.0024 ft/ft, and the dominant bed material is fine sand. In general, the streams do not function to their full potential. Having been channelized in the past and ditched to drain nearby wetlands for row crops, the streams do not access their floodplains as often as they naturally would have prior to the farm operations. In some cases, the streams are not hydraulically stable, causing erosion and undercutting of the banks. Habitat along the restoration reaches is poor in that there is no debris in the upper portions of the reach for fish cover or protection for other aquatic species. Vegetative diversity and habitat diversity is poor along the reaches, and offers no benefit to the wildlife in the area. D. Impact Justification and Mitigation 1. Avoidance and Minimization ]a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Due to the nature of this project, complete avoidance is not possible. Both stream and wetland impacts were considered when designing the Muddy Run II project. This project should uplift the ecological quality of streams and wetlands on site. The existing channel length for Muddy Run II is 8,643 LF with four stream crossings. The proposed project will result in 10,937 LF of stream with seven crossings. (See table below).

Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Impacts are minimized using a staged construction approach Where possible the channel will be constructed prior to turning stream flow into a segment. This approach allows minimization of the impact of each stage during the project construction. Additionally all work in wetlands and streams will be conducted during dry conditions and/or with mats to protect soil structure. Efforts will be made to preserve individual high value trees located within the stream restoration area. F.

Eric Kulz; NCDWQ, 22 July, 2013: • The plans for the project show a number of ditches that enter the conservation easement. According to the plans, flow from these ditches will be converted to diffuse flow through the use of earthen level spreaders. The plans show for live stakes to be installed on the level spreaders. Earthen level spreaders have been show repeatedly to fail, even with maintenance. The DWQ BMP Manual has discontinued including earthen level spreaders as approved stormwater structures. In addition, the proposal to install live stakes will result in concentrated flow as water will flow around the stems of the trees, likely increasing the erosion of the downstream face of the level spreader. Can the ditches instead be directed into wetland floodplain pools as on other EEP projects? Level spreaders are not a component of the diffuse flow structures. Where the structures are proposed, minor floodplain grading will be performed such that existing ditches outlet into a fat, fanned out area on the floodplain within the proposed easement. Existing ditches will be tied into the proposed channel where existing andproposed elevations will not allow for the installation of diffuse flow structures due to hydrologic trespass. See Sheet 44 for the revised diffuse flow structure detail. 2. T. Crumbles; USACE, 24 July, 2013: • As discussed during the field visit on 5 September, 2012, please ensure that all filled ditches be plugged and compacted to prevent scour and settling. Design plans show that abandoned ditches are to be filled and plugged per details on Sheet 42. • Also per the field discussion on 5 Sep 12, there is a concern by members of the IRT of possible tree mortality on Reaches 1, 2, and 3 due to the plugging of the ditches and the additional water within the reaches and adjoining forested lands. Vegetation along these reaches will be assessed during annual monitoring activities. If tree mortality affects 40% or greater of the canopy (visual estimation), then a remedial /supplemental planting plan will be developed and implemented. Text added to Section 10.7 Vegetative Success Criteria on pg. 75. • In general, the USACE does not support relocation of streams into areas that were not historically stream channels and is concerned over the amount of grading and excavation in the Goldsboro soil on reaches 3a and 3b across the upland ridge to the west. The proposed channel must maintain sufficient flow through this area to remain jurisdictional and become a higher functioning system. The work proposed shall in no way reflect a guarantee of credit generation if the performance standards and success criteria are not met throughout the monitoring period. Additionally, effects from the dewatering of the current features must be considered in the final mitigation plan and the subsequent application. Text added to Section 7.2.1, pg50. Approximately 1, 611 IF of the existing ditch flowing to the north at the Reach 3a /3b diversion structure will be impacted (dewatered). This length includes the ditch from the diversion structure down to where it enters the Muddy Creek floodplain. The NWP includes this anticipated impact to the existing channel. • Pg. 54, 7.2.1 provides a reference to proposed "macro- topography' features. Please ensure that these features end up vegetated and do not result in ponded areas with open water dominating. Revised text on pg. 54 to include maximum depth of wetland depressions. All wetland areas are to be planted per the planting plan on Sheets 35 37. The macro- topography features (wetland depressions) are to be constructed with a maximum depth of 6 inches and are not designed to be permanent pools. It is anticipated that open water will only be present after rainfall events due to overbank flows, and that open water areas will not be dominant. • Reach 3c currently flows through or adjacent to, existing jurisdictional wetlands. Please provide a discussion on the impacts to and protection measures for existing wetlands (high visibility fencing, avoidance). Impacts to existing wetlands need to be accounted for in the final mit plan and ensuing NWP application, including explanations on how the impacts /losses will be replaced. Construction notes on Sheet 40 state "EXISTING WETLANDS CANNOT BE ENCROACHED UPON UNDER ANY CIRCUMSTANCES IF NOT APPROVED AS DESIGNATED IMPACT AREAS. HIGH VISIBILITY FENCING MUST BE PLACED AROUND ALL EXISTING WETLANDS THAT ARE LOCATED ADJACENT TO CONSTRUCTION ACTIVITIES AND /OR ARE LOCATED WITHIN THE PROPOSED CONSERVATION EASEMENT. " The NWP includes all anticipated impacts to existing wetlands. The total wetland impacts are 0.078 ac for channel construction (permanent) and 0.080 acres for construction access (temporary). Permanent wetland impacts have been avoided to the extent possible and are offset by restored hydrology and appropriate watershed flow patterns.
