Suite 110 Raleigh, NC 27605 PCN Supplemental Information — Compass Point Mitigation Project B. Proiect Information and Prior Proiect Histor 3a. Describe the existiniz conditions on the site and the zeneral land use in the vicinity of the proiect at the time of this application: The Compass Point Mitigation Site ("Project") is located within a rural watershed in Yadkin County, approximately 4.5 miles northeast of Boonville. The Project lies within the Yadkin River Basin, North Carolina Department of Water Resources (NCDWR) sub -basin 03-07-02 and United States Geological Survey (USGS) 12 -digit hydrologic unit code (HUC) 030401011001. The total drainage area for the Project is 271 acres (0.42 mi2). Primary land use within the rural watershed consists of approximately 60.4 percent forest and 33.7 percent agricultural land. Impervious area covers less than one percent of the total watershed Within the agricultural land use, pastureland accounts for 62.5 percent of the area, and row crops account for approximately 37.5 percent of the area. Although the project watershed is primarily forested, the majority of the agricultural areas within the watershed are in close proximity to the Project and play a significant role in the degradation of the Project streams. These activities have negatively impacted both water quality and streambank stability along the Project streams and their tributaries. The resulting observed stressors include excess nutrient input, streambank erosion, sedimentation, livestock access to streams, channel modification, and the loss of riparian buffers. The Project area is comprised of a contiguous easement area along three unnamed tributaries that converge and drain directly to the Yadkin River. The easement has two agricultural crossings; one between DWI -C and DW1-B, and the second easement break is on DW2-B near the confluence with DW1-A. The stream channels include the main unnamed tributary and two additional tributaries that converge from the east, then split into eight reaches based on proposed treatment type. In general, all or portions of all eight Project reaches do not function to their full potential. Current conditions demonstrate significant habitat degradation as a result of impacts from agriculture, livestock production, and lack of riparian buffer. Being heavily eroded and incised, some of the streams do not access their floodplains as frequently as they naturally would have prior to agricultural operations. In many cases in the lower elevations, the riparian buffer is in poor condition where much of the riparian buffer is devoid of trees or shrubs up to the edge of the existing channel or comprised largely of invasive species. In some reaches, trees are present, but understory riparian buffer has been heavily impacted by cattle. Habitat along the majority of the restoration reaches is poor in that there is little woody debris or overhanging vegetation for fish cover or protection for other aquatic species. 3d. Explain the purpose of the proposed proiect. The objective for this restoration project is to restore and design natural waterways with the 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 treating invasive species. PCN Supplemental Information — Compass Point Mitigation Project 3e. Describe the overall oroiect in detail. including the tvne of eauinment to be used. Stream restoration efforts along the tributaries of the Project will be accomplished through analyses of geomorphic conditions and watershed characteristics. The design approach applies a combination of analytical and reference reach -based design methods that meet objectives commensurate with both ecological and geomorphic improvements. Proposed treatment activities may range from minor bank grading and planting to re-establishing stable planform and hydraulic geometry. For reaches requiring full restoration, natural design concepts have been applied and verified through rigorous engineering analyses and modeling. The objective of this approach is to design a geomorphically stable channel that provides habitat improvements and ties into the existing landscape. The Project will include priority I and II stream restoration, enhancement 1, enhancement II, and enhancement III. Stream restoration will incorporate the design of a single -thread meandering channel, with parameters based on data taken from reference sites, published empirical relationships, and best professional judgment. Engineering analysis will be performed using various hydrologic and hydraulic models to verify the design. A combination of methods will be used to estimate bankfull discharge, and larger flood events. A HEC -RAS model will then be used to simulate water surface elevations of flows generated by the hydrologic analysis. The development of the HEC model is an important component to the design; therefore, model input parameters are field verified when possible. Through this hydrologic analysis, the design discharge (typically referenced as bankfull or dominant discharge) will be determined. The subsequent design will be based on this calculated discharge. As part of the design process, a qualitative analysis of sediment supply will be performed by characterizing watershed conditions. A combination of windshield surveys, existing land use data, and historical aerial photography, followed up by ground truthing, will be analyzed to assess existing and past watershed conditions and to determine if any changes occurred that would significantly impact sediment supply. Design parameters developed through the analyses of reference reach data, watershed characterizations, and hydrologic and hydraulic modeling will be confirmed with shear stress and velocity analyses. Geomorphic and habitat studies will be performed concurrently with the engineering analyses. While stream design will be verified by simulations of hydrology and fluvial processes, analogs of desirable habitat features will be derived from reference sites and integrated into the project design. Both in -stream and riparian habitat features will be designed. In -stream structures will be used throughout the project to act as grade control and for bank stabilization by dissipating and redirecting the stream's energy. Bank stability may further be enhanced through the installation of brush toes, live stakes and cuttings bundles. Sections of abandoned stream channel will be backfilled with material excavated from on site to the elevation of the floodplain in areas adjacent to the new channel, installing channel plugs where necessary. The floodplain will be planted with native species creating a vegetated buffer, which will provide numerous water quality and ecological benefits. Stream banks will be stabilized using a combination of grading, erosion control matting, bare -root plantings, native material revetment techniques (i.e., bioengineering), structure placement, and sod transplants where possible. The stream and adjacent riparian areas will be protected by a minimum 50 -foot conservation easement which will be fenced to exclude livestock as needed. PCN Supplemental Information — Compass Point Mitigation Project The Project has been broken into the following design reaches: Reach DW1-A - This reach begins on the southwest end of the Project, flows northeast to a confluence with DW1-B and DW2-B, and totals 288 linear feet of Enhancement II. Open pasture is located adjacent to the reach. Enhancement activities will include improving habitat through livestock exclusion fencing and riparian planting. The livestock exclusion fencing will provide wildlife corridors throughout the Project area and will remove livestock access to the riparian areas. A flow gauge will be installed midway on the reach to monitor hydrology. Reach DWI -B - This reach begins on the southern end of the Project from DW 1-A and DW2-B, flows north to DWI -C, and totals 1,922 linear feet of Priority I/II restoration. Actively managed pasture is located adjacent to the reach on the upstream end. The downstream end is surrounded by intermittently grazed pasture and disturbed secondary growth in an area with previous timber harvest. Restoration activities will include constructing a new channel within the natural valley with appropriate dimensions and pattern and backfilling the abandoned channel. In -stream structures such as log sills, brush toes, and log vanes will be installed for stability and to improve habitat. Habitat will further be improved through buffer plantings and livestock exclusion. Proposed buffer activities will improve riparian areas that will filter runoff from adjacent pastures, thereby reducing nutrient and sediment loads to the channel. Reach DW1-C — This reach begins on the north end of the Project from DWI -B, and flows northeast to a culvert crossing and DW1-D. This reach totals 566 linear feet of Priority 1/II restoration, beginning immediately downstream of a bedrock drop structure at the bottom of DW 1-B. Any sections of the existing road will be decommissioned in the easement and planted. Intermittently active pasture and disturbed woodland is located adjacent to the reach. Restoration activities will include constructing a new channel within the natural valley with appropriate dimensions and pattern, cutting a floodplain bench and backfilling the abandoned channel. In -stream structures such as log sills, brush toes, and log vanes will be installed for stability and to improve habitat. Habitat will further be improved through buffer plantings and livestock exclusion. Livestock exclusion fencing will provide wildlife corridors throughout the Project area and will remove livestock access to the riparian areas. Reach DW1-D - This reach begins at the downstream end of DWI -C and proposed culvert crossing in the northern end of the Project, and flows northeast to DW 1-E. The reach totals 759 linear feet of Priority UII restoration. Restoration activities will include constructing a floodplain bench to aid in connectivity to the existing floodplain and constructing a new channel with appropriate dimensions and pattern. When possible, bed material will be harvested and reused to create stable bed features post -construction. In - stream structures such as log sills, brush toes, and log vanes will be installed for stability and to improve habitat. Habitat will further be improved through buffer plantings and livestock exclusion. Proposed buffer activities will improve riparian areas that will filter runoff from adjacent pastures, thereby reducing nutrient and sediment loads to the channel. Reach DW1-E - This reach begins on the north end of the Project, from DWI -D and flows north until it drains to the Yadkin River. This reach totals 432 linear feet of Enhancement III. Managed cropland is located adjacent to the reach. Enhancement activities will include improving habitat through livestock exclusion fencing and installing a boulder grade control structure at the top of the reach where DW 1-D enters to prevent further upstream channel erosion during Yadkin River flood events. Reach DW2-A - This reach begins on the southeast end of the Project, and flows west to DW2-B. The totals 968 linear feet of Enhancement I. Sparse woodland and actively managed pasture is located PCN Supplemental Information — Compass Point Mitigation Project adjacent to the reach. Enhancement activities will include targeted bank stabilization, riparian buffer planting, and installation of livestock exclusion fencing. An existing ford crossing will also be removed. Proposed buffer activities will improve riparian areas that will filter runoff from adjacent pastures, thereby reducing nutrient and sediment loads to the channel. Reach DW2-B - This reach begins at the downstream end of DW2-A, and flows north to the confluence with DWI -A to become DWI -B. This reach totals 277 linear feet of Priority I Restoration. Actively managed pasture is present on both sides of the reach. Restoration activities will include constructing a new channel within the natural valley with appropriate dimensions pattern and backfilling the abandoned channel. Native bed material will be harvested when possible. In -stream structures such as log sills, brush toes, and log vanes will be installed for stability and to improve habitat. Habitat will further be improved through buffer plantings and livestock exclusion. A ford crossing will be installed along this reach (Figure 10). Proposed buffer activities will improve riparian areas that will filter runoff from adjacent pastures, thereby reducing nutrient and sediment loads to the channel. Reach DW3 - This reach begins on the south end of the Project at the adjacent powerline easement, and flows north to DW2-A. This reach totals 93 linear feet of Enhancement I. Disturbed woodland, intermittently grazed pasture, and a maintained powerline easement is located adjacent to the reach. Enhancement activities will include improving habitat through livestock exclusion fencing, and riparian buffer planting. The livestock exclusion fencing will provide wildlife corridors throughout the Project area and will remove livestock access to the riparian areas.

Comments Impacts due to the relocation of the stream to natural valley will provide a net gain in ecological function to the stream system. Active pasture is located adjacent to all project reaches. Restoration is proposed along several reaches to address channel degradation and bank erosion caused by cattle access (DW1-B, DWI - C, DWI -D, and DW2-B). For stream relocation and impacts: Stream Impact 1, the existing length is 514 linear feet (LF), and the new length will be 485 LF; Stream Impact 4, the existing stream length is 2,014 LF and the new length will be 1,922 LF; Stream Impact 5, the existing stream length is 600 LF, the new length will be 566 LF; Stream Impact 8, the existing stream length is for the entire reach is 741, however, only 487 LF will be impacted. There are two impacts associated with the installation of a culvert (S6 and S7), where the permanent impacts include the installation of a 24 -inch pipe, and the temporary impacts are due to earthwork movement adjacent to culvert location. Additionally, there is one permanent impact (S2) associated with the installation of a ford crossing. D. Impact Justification and Mitigation la. 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 Compass Point Mitigation project. This project should uplift the ecological quality of streams and wetlands on site. The existing project channel length is 5,350 LF. The proposed project will result in 5,304 LF of stream. Ib. Specifically describe measures taken to avoid or minimize the proposed impacts throu,-h 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. Supplementary Information 8b. If yes, explain how proiect meets FEMA requirements PCN Supplemental Information — Compass Point Mitigation Project According to the North Carolina Floodplain Mapping Information System, the Project includes a portion of the of Project within the FEMA 100 -year flood zone (Zone AE, one percent annual chance of flooding). Reaches DW1-E and DW1-D, where the Project connects to the Yadkin River, is in a regulated floodway zone. Hydraulic modeling will be required to determine whether restoration activities will have an effect on 100 -year flood elevations downstream. The design and permitting of the mitigation will include coordination with the Yadkin County Floodplain Administrator and a No -Rise Certification or CLOMR/LOMR will be secured. No hydrologic trespass will be permitted to adjacent properties upstream or downstream of the project. The Project can be found on Flood Insurance Rate Map (FIRM) Panel 37171C (map number 3710590000K), effective date August 18, 2009. Aquatic Resources Table Update Stream IDs have changed during the design process. From the original JD submittal, DWI -A has been broken out into the design reaches DW2-B and DW1-B. This change in naming changed the subsequent naming convention along the main tributary of the project. From the original submittal the following have been changed: DWI -B is now DWI -C; DWI -C is now DWI -D; DWI -D is now DWI -E; DW2 is now DWI -A; DW6 is now DW2-A; and DW3 was added into the project.

The Project lies within the Yadkin River Basin, North Carolina Department of Water Resources (NCDWR) sub -basin 03-07-02 and United States Geological Survey (USGS) 12 -digit hydrologic unit code (HUC) 030401011001 (Figure 1). The Project is being designed to help meet compensatory mitigation requirements for stream impacts in the HUC 03040101. The Project proposes to restore 3,549 linear feet (LF), enhance 1,755 LF of existing stream, and provide water quality benefit for 271 acres of drainage area. The Project is in the Northern Inner Piedmont Level IV ecoregion. The Project is comprised of a single easement location along three unnamed tributaries to the Yadkin River, totaling 5,350 linear feet. The stream mitigation components are summarized in Table 1 and Figure 10. The Project is accessible from Pulliam Road. Coordinates for the Project are as follows: 36.269624, -80.638420. 1.2 Project Outcomes The streams proposed for restoration have been significantly impacted by livestock production, agricultural practices, and a lack of riparian buffer. Proposed improvements to the Project will help meet the river basin needs expressed in the 2009 Upper Yadkin Pee -Dee River Basin Restoration Priorities (RBRP) as well as ecological improvements to riparian corridor within the easement. Through stream restoration and enhancement, the Project presents 5,304 LF of proposed stream, generating 4,161 Cool Stream Mitigation Units (SMU) (Table 1). This mitigation plan is consistent with the October 20, 2017 IRT site visit notes (Appendix H). Table 1.
