A Bank Erosion Hazard Index assessment of the project reach classified the banks as having "High" and "Very High" BEHI ratings. These BEHI ratings are associated with high levels of sediment and nutrient export in the stream. The bank stabilization measures proposed will reduce streambank erosion, stop excessive sedimentation from areas with high erosion potential, and re -center stream flows in the channel, thus reducing excessive shear stress along the stream banks, which reduces erosion rates. 4b.

Explain the purpose of the proposed project:* Freese and Nichols, Inc. (FNI) has been asked to assist the Town of Southern Pines for the assessment, analysis, and development of alternative engineering solutions for a section of McDeeds Creek located at 500 W Pennsylvania Avenue. Significant streambank erosion has been observed along the Stream that has created potential risk to the infrastructure, including an aerial sewer forcernain situated at the upstream terminus of the project, and the parking areas behind the Town Fire and Police Departments. Bank erosion has also contributed to a likely decrease in downstream water quality due to sediment loading. The scope of work proposes to stabilize approximately 725 linear feet of the Stream located within the 7.15-acre area behind the Town Fire and Police Departments. Stabilization of area that have been characterized with high erosion rates or high erosion potential will reduce sediment loading, and will reduce the risk to infrastructure. 4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:* Restoration Approach: The restoration approach to McDeeds Creek will involve streambank stabilization/restoration on erosive streambanks at areas of critical infrastructure, and centering of channel flows to reduce erosion potential in other areas in the project reach. Restoration will involve the use of bank stabilization techniques based on bio-engineering using slope stabilization technology and deep-rooted woody vegetation to ensure long-term stability of the streambank soil. A summary of the proposed conceptual restoration approach is as follows: • Rock vanes are suggested to provide in -channel grade control and center flows in the channel • Sediment deposition has occurred at the downstream extent of the project reach. Grading will be recommended in these areas to reshape the channel to a stable channel form. • The ultimate goal of all of the restoration measures is to reduce bank angle or increase surface protection and install rooted vegetation to increase bank and slope stability and reduce erosion rates and nutrient export rates. Description of Construction Methods and Erosion and Sediment Controls: The construction of the McDeeds Creek Stabilization Project will followtypical methods and erosion control techniques of stream restoration. This will involve the use of heavy machinery such as excavators, to accomplish the grading needed to stabilize streambanks along the channel. Some clearing and grubbing will be required where slope grading is proposed. As is typical of stream restoration projects, some machinery will need to enter the channel to conduct grading and earth -moving operations and to install in -channel structures. A pump around will be utilized to allow for earthmoving to be conducted in dry conditions, reducing the amount of sediment and silt transported downstream during construction. Ground - stabilization requirements will be followed to prevent erosion and runoff of sediments when soils are susceptible immediately after construction. This will include the use of coir matting on the streambanks, temporary seeding to provide immediate ground stabilization, and planting of permanent vegetation including perennial herbaceous plants, live stakes and bare root seedlings on the streambanks and disturbed upland areas. Native riparian species such as black willow, alder, and silky dogwood will be used in the permanent plantings. Area 1 (STA 0+42to 1+27): Currently, stream bank erosion has caused bank instability at an aerial sewer crossing upstream of the police station, which will be stabilized with a proposed 31 linear foot 1-tier stacked rock wall that will be constructed at or within the ordinary high water (OHW). It is expected that the overall volume of fill in Area 1 will not exceed 9 cu yd below ordinary high water. Approximately 4.6 cu yd of fill belowOHW, where the rock toe will be countersunk into the bed and bank to provide a stable foundation for the geobag and soil lift bio-engineered walls, is expected. All other fills in Area 1 will be outside of the OHW and will stabilize the highly unstable bank around the aerial sewer crossing. A rock vane in -stream structure at STA 1+27 will be installed downstream of the aerial sewer to direct stream flows and provide grade control. Area 2 (STA 2+26 to 2+52): A stormwater channel running along the police station from Pennsylvania Avenue to McDeeds Creek has created a head cut that threatens the stability of the stream banks downstream of the impairment. This area will be stabilized with a step pool within the stormwater channel and a 26 linear foot 1-tier stacked rock wall at the transition area between the stormwater channel and McDeeds Creek. Overall volume of fill will be limited to the 1-tier stacked rock wall that will not exceed 5 cu yds of fill within ordinary high water. Area 3 (STA 3+47 to 3+82): Additional stabilization issues related to the sheetpile wall constructed for the police station parking lot will require approximately 38 linear feet of new sheetpile construction behind the existing sheetpile wall. The affect section of the existing sheetpile wall and associated fill will be removed after installation of the new sheetpile area. A stormwater channel will be constructed outside of the stream between the sheetpile wall and the parking lot to convey stormwater from the police station in a manner that will not create backwatering behind the sheetpile area. A 1-tier stacked rock wall will be constructed at the terminus of the stormwater channel and McDeeds Creek to transition the bank back to native material. A reduction of filled area is expected during the sheetpile construction, with an approximate reduction of 20 cu yd of fill removed from behind the existing sheetpile wall, which will return the cross sectional area of Area 3 to the observed stable cross sectional dimensions of the project reach. Area 4 (STA 4+25 to 7+09): Area 4 is characterized by steep slopes from the edge of the police and fire station parking lots, resulting in areas where 3-tiered bioengineered areas with soil layer lifts or geobags are required to properly stabilize eroding banks. The area has colluvial deposition from the upslope areas, which has destabilized the stream channel, creating areas of high shear stress during bankfull events. These areas have weakened and require more significant bio-engineering support. The bank areas between the proposed bioengineered walls have lower erosion potential and will be stabilized using live stake plantings. Approximately 156 linear feet of 3-tiered rock wall stabilization with soil layer lifts or geobags will be constructed. It is expected that the overall volume of fill in Area 4 will not exceed 25 cu yd below ordinary high water. A rock vane in -stream structure will be installed at STA 6+12 and STA 7+09 to provide grade control and center channel flows at the downstream terminus of the project and provide grade control between the box culvert at STA 7+37 that runs under SE Service Road and the project reach. Atotal of 20,135 square feet (0.46 acres) of the project area will be disturbed in the project area, to include access and haul roads, bank stabilization, and grading areas. All disturbances related to temporary construction access will be restored to pre -construction contours and planted with native vegetation. All proposed stream banks use natural stabilization techniques that will not exceed 500 linear feet and meet the general conditions thresholds of NC Division of Water Resources (DWR) Water Quality General Certification 4134, and do not require written approval from DWR. 4j.

Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:* Bank stabilization measures that require construction of soil layer lifts or geobags are limited to the areas that either current have high erosivity, or in areas that have high or very high erosion potential. In -stream structures were used to provide grade control and center flows within the channel, which will reduce the erosion potential in other bank areas within the project reach. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:* Construction activities within the project reach will be limited to bank stabilization and sheetpile replacement to address critical bank failure and excessive erosion potential, as well as installation of in -stream structures to direct flow. A pump around will be used to allowfor earthmoving to be conducted in dry conditions, reducing the amount of sediment and silt transported downstream during construction. Temporary access roads are situated in areas that are not within WOTUS, and will be returned to pre -construction contours and planted with native vegetation. All applicable NC Erosion and Sediment controls will be implemented and maintained during construction. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State? ✓ Yes r- No 2b. If this project DOES NOT require Compensatory Mitigation, explain why: The project uses ecosystem restoration to provide bank stabilization, sediment reduction, increase in -stream habitat, and increase ecosystem uplift within the project reach. No permanent loss of WOTUS will result from the project, and the project will increase the quality of waters within the project area. All temporary impacts will be returned to pre -construction contours and stabilized as required by NWP conditions.

Full Name:* Jason Steele Signature * Date 4/13/2021 Project Description, Purpose and Need: Freese and Nichols, Inc. (FNI) has been asked to assist the Town of Southern Pines for the assessment, analysis, and development of alternative engineering solutions for a section of McDeeds Creek located at 500 Pennsylvania Avenue. Significant streambank erosion has been observed along the Stream that has created potential risk to the infrastructure, including an aerial sewer forcemain situated at the upstream terminus of the project, and the parking areas behind the Town Fire and Police Departments. Bank erosion has also contributed to a likely decrease in downstream water quality due to sediment loading. The scope of work proposes to stabilize approximately 725 linear feet of the Stream located within the 7.15-acre area behind the Town Fire and Police Departments. Stablization of area that have been characterized with high erosion rates or high erosion potential will reduce sediment loading, and will reduce the risk to infrastructure. The section of McDeeds Creek that flows behind the Town Police and Fire stations is heavily incised with active erosion along a majority of the reach. A Bank Erosion Hazard Index assessment of the project reach classified the banks as having "High" and "Very High" BEHI ratings. These BEHI ratings are associated with high levels of sediment and nutrient export in the stream. The bank stabilization measures proposed will reduce streambank erosion, stop excessive sedimentation from areas with high erosion potential, and re -center stream flows in the channel, thus reducing excessive shear stress along the stream banks, which reduces erosion rates. Restoration Approach: The restoration approach to McDeeds Creek will involve streambank stabilization/restoration on erosive streambanks at areas of critical infrastructure, and centering of channel flows to reduce erosion potential in other areas in the project reach. Restoration will involve the use of bank stabilization techniques based on bio-engineering using slope stabilization technology and deep-rooted woody vegetation to ensure long-term stability of the streambank soil. A summary of the proposed conceptual restoration approach is as follows: • Rock vanes are suggested to provide in -channel grade control and center flows in the channel • Sediment deposition has occurred at the downstream extent of the project reach. Grading will be recommended in these areas to reshape the channel to a stable channel form. • The ultimate goal of all of the restoration measures is to reduce bank angle or increase surface protection and install rooted vegetation to increase bank and slope stability and reduce erosion rates and nutrient export rates. Description of Construction Methods and Erosion and Sediment Controls The construction of the McDeeds Creek Stabilization Project will follow typical methods and erosion control techniques of stream restoration. This will involve the use of heavy machinery such as excavators, to accomplish the grading needed to stabilize streambanks along the channel. Some clearing and grubbing will be required where slope grading is proposed. As is typical of stream restoration projects, some machinery will need to enter the channel to conduct grading and earth -moving operations and to install in -channel structures. A pump around will be utilized to allow for earthmoving to be conducted in dry conditions, reducing the amount of sediment and silt transported downstream during construction. Ground -stabilization requirements will be followed to prevent erosion and runoff of sediments when soils are susceptible immediately after construction. This will include the use of coir matting on the streambanks, temporary seeding to provide immediate ground stabilization, and planting of permanent vegetation including perennial herbaceous plants, live stakes and bare root seedlings on the streambanks and disturbed upland areas. Native riparian species such as black willow, alder, and silky dogwood will be used in the permanent plantings. Area 1 (STA 0+42 to 1+27): Currently, stream bank erosion has caused bank instability at an aerial sewer crossing upstream of the police station, which will be stabilized with a proposed 31 linear foot 1-tier stacked rock wall that will be constructed at or within the ordinary high water (OHW). It is expected that the overall volume of fill in Area 1 will not exceed 9 cu yd below ordinary high water. Approximately 4.6 cu yd of fill below OHW, where the rock toe will be countersunk into the bed and bank to provide a stable foundation for the geobag and soil lift bio-engineered walls, is expected. All other fills in Area 1 will be outside of the OHW and will stabilize the highly unstable bank around the aerial sewer crossing. A rock vane in -stream structure at STA 1+27 will be installed downstream of the aerial sewer to direct stream flows and provide grade control. Area 2 (STA 2+26 to 2+52): A stormwater channel running along the police station from Pennsylvania Avenue to McDeeds Creek has created a head cut that threatens the stability of the stream banks downstream of the impairment. This area will be stabilized with a step pool within the stormwater channel and a 26 linear foot 1-tier stacked rock wall at the transition area between the stormwater channel and McDeeds Creek. Overall volume of fill will be limited to the 1-tier stacked rock wall that will not exceed 5 cu yds of fill within ordinary high water. Area 3 (STA 3+47 to 3+82): Additional stabilization issues related to the sheetpile wall constructed for the police station parking lot will require approximately 38 linear feet of new sheetpile construction behind the existing sheetpile wall. The affect section of the existing sheetpile wall and associated fill will be removed after installation of the new sheetpile area. A stormwater channel will be constructed outside of the stream between the sheetpile wall and the parking lot to convey stormwater from the police station in a manner that will not create backwatering behind the sheetpile area. A 1-tier stacked rock wall will be constructed at the terminus of the stormwater channel and McDeeds Creek to transition the bank back to native material. A reduction of filled area is expected during the sheetpile construction, with an approximate reduction of 20 cu yd of fill removed from behind the existing sheetpile wall, which will return the cross sectional area of Area 3 to the observed stable cross sectional dimensions of the project reach. Area 4 (STA 4+25 to 7+09): Area 4 is characterized by steep slopes from the edge of the police and fire station parking lots, resulting in areas where 3-tiered bioengineered areas with soil layer lifts or geobags are required to properly stabilize eroding banks. The area has colluvial deposition from the upslope areas, which has destabilized the stream channel, creating areas of high shear stress during bankfull events. These areas have weakened and require more significant bio-engineering support. The bank areas between the proposed bioengineered walls have lower erosion potential and will be stabilized using live stake plantings. Approximately 156 linear feet of 3-tiered rock wall stabilization with soil layer lifts or geobags will be constructed. It is expected that the overall volume of fill in Area 4 will not exceed 25 cu yd below ordinary high water. A rock vane in -stream structure will be installed at STA 6+12 and STA 7+09 to provide grade control and center channel flows at the downstream terminus of the project and provide grade control between the box culvert at STA 7+37 that runs under SE Service Road and the project reach. A total of 20,135 square feet (0.46 acres) of the project area will be disturbed in the project area, to include access and haul roads, bank stabilization, and grading areas. All disturbances related to temporary construction access will be restored to pre -construction contours and planted with native vegetation. All proposed stream banks use natural stabilization techniques that will not exceed 500 linear feet and meet the general conditions thresholds of NC Division of Water Resources (DWR) Water Quality General Certification 4134, and do not require written approval from DWR.

Please give a brief project description below and include location information.* Freese and Nichols, Inc. (FNI) has been asked to assist the Town of Southern Pines for the assessment, analysis, and development of alternative engineering solutions for a section of McDeeds Creek located at 500 Pennsylvania Avenue. Significant streambank erosion has been observed along the Stream that has created potential risk to the infrastructure, including an aerial sewer forcemain situated at the upstream terminus of the project, and the parking areas behind the Town Fire and Police Departments. Bank erosion has also contributed to a likely decrease in downstream water quality due to sediment loading. The scope of work proposes to stabilize approximately 725 linear feet of the Stream located within the 7.15- acre area behind the Town Fire and Police Departments. Stablization of area that have been characterized with high erosion rates or high erosion potential will reduce sediment loading, and will reduce the risk to infrastructure.
