The purpose of the proposed project is to repair and stabilize streams at four sites that experienced damage during Hurricane Florence, and this permit is for Site 3 of the overall project. The stream repair and stabilization aim to improve the water quality functions of the stream and floodplain through enhancement of the natural ecosystem and riparian community, control and reduction of streambank erosion, and improvement of aquatic and terrestrial habitat. Additionally, the project is proposing the repair and maintenance of several existing aerial waterline and sewer crossings that were damaged during Hurricane Florence. Site 3 of the project consists of the repair and stabilization of a length of two tributaries to Third Fork Creek as well as the repair and maintenance of an existing aerial sewer crossing. Kimley-Horn staff delineated the project study area on June 2, 2020 and identified 2 streams (S9 and S10). A Preliminary Jurisdictional Determination (SAW-2020-01177) was issued by April Norton of the USACE on April 12, 2020. A Buffer Determination (NBRRO #20-208) was issued by Erin Deck of the NCDWR on August 11, 2020. The Site 3 proposed stream repair will include the grading of damaged and unstable stream banks to match natural channel contours, the placement of rip rap and boulder toe protection along the stream banks to provide stabilization, and the installation of riffles composed of rip rap within the stream to establish grade control, reduce streambank erosion, facilitate sediment transport, and enhance aquatic species habitat. The Piedmont Regional Hydraulic Geometry Curve data was used as a reference point for the proposed stream contours and grade control structures. The proposed work was designed to Ki m ey >>> H o r n Page 2 match natural conditions found along unnamed perennial and intermittent tributaries to Third Fork Creek. As part of the stream repair, stream banks that have been graded and disturbed will be replanted with live stakes, bare roots, and herbaceous plugs to promote vegetation establishment and restore the overall function of the riparian buffers. In addition, Site 3 of the project proposes to perform maintenance repairs on an existing aerial sewer crossing that was damaged during Hurricane Florence. As part of this repair and maintenance, two new support piers, outside of the OHWM, will be installed for an existing aerial sewer crossing and approximately 68 linear feet of 8-inch P-401 lined DI carrier sanitary sewer pipes encased with approximately 58 linear feet of 16-inch steel casing will be constructed to replace the existing line. Permanent, no net loss of water impacts and temporary impacts to two unnamed tributaries to Third Fork Creek will result from the proposed stream restoration. The proposed stream restoration will result in permanent and temporary impacts to the Jordan Lake Riparian Buffer Zones along one perennial tributary to Third Fork Creek. All temporarily impacted areas will be restored and replanted upon completion of the proposed stream restoration. Permanent and temporary buffer impacts will result from the repair and replacement of an existing aerial sewer line across stream S9. The proposed replacement will be located within the existing sewer easement and will install two new pier support structures in Buffer Zone 1. Temporary impacts will be limited to a temporary pipe crossing of stream S10 and otherwise confined within the existing sewer easement. Temporary impacts outside of the existing sewer easement will be restored to pre - construction contours and re -vegetated upon completion of the proposed project. No compensatory mitigation is proposed as part of this permit application. The proposed stream restoration and enhancement serves to improve the water quality within the watershed and will not result in a loss of water; therefore, no stream mitigation is proposed. Additionally, in accordance with the Jordan Lake Watershed Buffer Rules, buffer impacts resulting from "Restoration or enhancement" and "Utility, electric, underground, perpendicular crossings" are considered allowable or exempt buffer impacts and therefore do not require mitigation.

Total jurisdictional ditch impact in square feet: 31. Total permanent stream impacts: 201 31. Total stream and ditch impacts: 385 31. Total temporary stream impacts: 184 3j. Comments: Unavoidable permanent impacts to two unnamed tributaries to Third Fork Creek (S9 and S10) will result from the restoration and enhancement of the channel and banks, resulting in no loss of waters. Stream repair, restoration, and enhancement activities will include the grading of damaged and unstable stream banks to match natural channel contours, the placement of rip rap and boulder toe protection along the stream banks to provide stabilization, and the installation of rip rap embankment protection at drainage swales to prevent future erosion and sedimentation. The construction of riffles within the stream is also proposed to establish grade control, facilitate sediment transport, and enhance aquatic species habitat. Proposed temporary impacts to S9 and S10 will result from temporary access to facilitate construction/installation of stream enhancement structures, access for streambank repair, and for temporary devatering via stream diversion to allow work in the dry. No permanent or temporary stream impacts will result from the replacement of the ebsting aerial sewer line and support structures. However, temporary impacts will result from the removal of the ebsting aerial crossing. This temporarily impacted area is covered under the permanent stream restoration impacts. Additionally, appropmately 66 linear feet of stream S10 will be temporarily piped to allow for construction access to the Site. Upon completion of the project, the temporary pipe will be removed and the channel restored to pre-epsting conditions. 6. Buffer Impacts (for DWR) 6a. Project is in which protect basin(s)?

Comments: Permanent buffer zone 1 impacts at Site 3 will result from streambank stabilization activities including the grading back of stream banks and the installation of structures to prevent future erosion. Additionally, permanent buffer impacts will occur at Site 3 due to the replacement of an extsting aerial sewer line crossing and the construction of two new support piers. Temporary impacts at Site 3 will result from the necessary temporary access to construct the proposed projects. Temporarily impacted areas will be returned to pre-epsting contours and planted with native vegetation upon completion of the proposed work. The sewer line replacement will be located within the epsting sewer line easement. Supporting Documentation 06_EW P_Site3_lmpactFig u re. pdf E. Impact Justification and Mitigation 1. Avoidance and Minimization 8.7MB 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project: The project has been designed to improve the water quality functions of the streams and the associated floodplain, enhance and protect the natural ecosystem and riparian community, control and reduce future streambank erosion, and restore aquatic habitat. Temporary construction and staging areas for the stream repair and sewer line replacement have been located outside of jurisdictional areas to the extent possible while still allowing for the necessary access points to construct the project. Additionally, the sewer maintenance includes the repair and replacement of an extsting aerial sewer line, where new support piers will be located outside of the OHWM and within extsting sewer easement, resulting in minimal impacts to riparian buffers. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques: Impacts to streams and protected riparian buffers within the corridor will be avoided throughout the construction process by equipment, materials, and access corridors to the extent possible. Where feasible, staging and construction access routes will be located in upland areas throughout the corridor. Silt fencing will be installed around the limits of disturbance to help ensure that all construction equipment will remain within the project area throughout the construction process. Sediment control measures will be used to reduce stormwater impacts to receiving waters and minimize runoff from the construction sites. Pump-arounds or water diversion devices will be installed within the streams to allowfor work in the dry. All temporarily impacted areas will be returned to pre-epsting condition and replanted with native vegetation upon completion of 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? 4 Yes O No 2b. If this project DOES NOT require Compensatory Mitigation, explain why: The proposed stream restoration and enhancement serves to improve the water quality within the watershed and will not result in a loss of voter; therefore, no stream mitigation is proposed. Additionally, in accordance with the Jordan Lake Watershed Buffer Rules, buffer impacts resulting from "Restoration or enhancement' and "Utility, electric, underground, perpendicular crossings" are considered allowable or exempt buffer impacts and therefore do not require mitigation.

Stephanie Goss Please give a brief project description below.* The proposed project, Emergency Watershed Protection (EWP) Streambank Repair: Site 3, is located within the riparian corridor of twv tributaries to Third Fork Creek, south of Ward Street and east of James Street in Durham County, North Carolina. The area surrounding the project area is largely residential housing and scattered commercial development. The proposed project is part of a larger undertaking that is proposing to repair and stabilize streams at four sites and to repair and maintain several existing aerial waterline and sewer crossings that experienced damage during Hurricane Florence. Site 3 of this larger undertaking consists of the repair and stabilization of a length of two tributaries to Third Fork Creek as well as the repair and maintenance of an existing aerial sewer crossing. After discussions with the USACE, it is assumed that the project will qualify for authorization under both a Nationwide Permit 3 (Maintenance) and a Nationwide Permit 27 (Aquatic Habitat Restoration, Enhancement, and Establishment Activities). The proposed stream repair will include the grading of damaged and unstable stream banks to match natural channel contours, the placement of rip rap and boulder toe protection along the stream banks to provide stabilization. The project is also proposing the construction of riffles composed of rip rap within the stream to establish grade control, facilitate sediment transport, and enhance aquatic species habitat. Debris from an adjacent concrete wall that was damaged will be removed from within the stream. As part of the stream repair, stream banks that have been graded and disturbed will be replanted with live stakes, bare roots, and herbaceous plugs to promote vegetation establishment and restore the overall function of the riparian buffers. In addition, Site 3 of the project proposes to perform maintenance repairs on an existing aerial sewer crossing that was damaged during Hurricane Florence. As part of this repair and maintenance, two new support piers, outside of the OHWM, will be installed for an existing aerial sewer crossing and approximately 20 linear feet of DI sewer with an 8-inch P-401 lined DIP within approximately 18 linear feet of 16-inch steel casing will be constructed. Please give a couple of dates you are available for a meeting. 12/10/2020 Please attach the documentation you would like to have the meeting about.
