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 Site encompasses approximately 50.2 acres and is located in the city of Durham, North Carolina, within Durham County. The Site is bound by residential homes, commercial development, and Cheek Road to the north. The Site contains mostly forested areas with the central portion of the property having been clearcut within the last 5 years. There are multiple stream and wetland features throughout the Site along the sanitary sewer easement and drainages. Approximately 60% of the Site is comprised of forested areas while 20% has been recently clearcut and 20% is a maintained sanitary sewer easement. On December 6, 2018, Timmons Group delineated approximately 1,495 linear feet of intermittent stream, 2,693 linear feet of perennial stream, 1.4 acres of PFO wetland, and 0.1 acres of PEM wetland. 3b.

Proposed Activity Provide a detailed description of the proposed activity including its purpose and include the type of equipment to be used:* The proposed recreational development, known as Hoover Road Athletic Park, will consist of four soccer fields, a restroom and shelter structure, an access road connected to Hoover Road, stormwater control measures (SCMs), and underground utilities (i.e. water and gravity sanitary sewer). The project will be constructed in one (1) phase. Phase 1 includes site clearing and grading, utility implementation and site development. The project was previously permitted under Nationwide Permit 39 (USAGE SAW- 2019-00057) and General Certification 4139 (DWR #19-0810). Under the previous permit, Phase 1 was to include site clearing/grading, a construction entrance access from Hoover Road. Stream Impact 1 was to be included in Phase 1 and is associated with the instillation of a 72" RCP culvert with flared end sections totaling 104 linear feet of impacts for a permanent roadway crossing. An existing culvert at Stream Impact Location 2, which had not previously been permitted, was proposed to be removed and the stream to be returned to its natural contours and functions was to also be incorporated in Phase 1. A 6" PVC sanitary sewer line was to be trenched and filled across an existing stream then returned to its original contours. Following changes to the proposed Site plans, rip rap will temporarily be installed at the existing crossing to be removed (Impact Location 2) to utilize this crossing as a necessary temporary construction access for the Site. Stream restoration at this location is no longer proposed to take place during Phase 1 of construction and the newly proposed rip rap installation will increase temporary buffer disturbance. However, following completion of construction, the culvert and rip rap will be removed and the stream and associated buffer will be returned to its natural contours and functions. Additionally, the culvert tupe at Stream Impact Location 1 has changed to a 96" wide by 72" tall box culvert. The overall stream impact amount and buffer impact has not changed. Additional impacts to waters of the U.S. are not proposed. The proposed project is a single and complete project with appropriate land use control measures in place for specific areas which require them. Traditional equipment will be used consisting of front-end loaders, bulldozers, paving equipment, graders, and earth movers.

Project History 6a. Have permits or certifications been requested or obtained for this project (including all prior phases) in the past?* r Yes r No 6b. List any permits/approvals that have been requested or obtained for this project in the past. Application Date Date Issued Permit Type 6/14/2019 10/2/2019 USACE NWP 39 6/14/2019 8/23/2019 NCDEQ GC 4139 6c. Please explain and detail according to "help file" instructions.* USACE SAW-2019-00057 was approved for Nationwide Permit 39 for: 104 linear feet of permanent impacts to stream from the installation of 82.28 feet of a 72" reinforced concrete pipe (RCP) necessary for an access road, 35 linear feet of temporary impacts to stream for the removal of an existing, unauthorized access road, and 34 linear feet of temporary impacts to stream for the installation of a sanitary sewer utility line. Special conditions listed within the permit specified that within 30 days of removing the authorized access drive depicted on the site plans, the applicant or their agent must notify the USACE to verify that the work had been completed. DWR #19-0810 was approved for Water Quality General Certification Number 4139 for: 104 linear feet of permanent stream impacts for fill, 35 linear feet of temporary impacts for restoration/dredging, and 34 linear feet of temporary stream impacts for restoration. Permitted buffer impacts included: 5,417 square feet of permanent Zone 1 buffer impacts and 7,742 square feet of permanent Zone 2 buffer impacts for a road crossing, 2,444 square feet of temporary Zone 1 buffer impacts and 610 square feet of temporary Zone 2 buffer impacts for restoration, 1,716 square feet of temporary Zone 1 buffer impacts and 2,307 square feet of temporary Zone 2 buffer impacts for a utility crossing, and 618 square feet of temporary Zone 1 buffer impacts and 1,027 square feet of temporary Zone 2 buffer impacts for stormwater discharge. Due to the absence of wetland impacts and total permanent stream impacts of less than 150-feet, no wetland or stream mitigation was required. Further, all proposed buffer impacts fall under the exempt or allowable (now deemed allowable and allowable upon authorization). Therefore, no buffer mitigation is required. 7.

Updated Site plans are proposing to use the area as a necessary temporary construction access road for the project, increasing the temporary buffer disturbance following rip rap installation at the culvert outfall. Upon completion of the work, the crossing will still be removed and the stream and buffer will be restored per the original permitted plans. All other buffer impacts remain the same from the initial permit approval. However, it was noted upon re -issuance that buffer Zones 1 and 2 were flipped in the original permit application and approval (initially 20-ft in Zone 1 and 30-ft in Zone 2). Therefore, the plans have been revised to accurately represent a 30-ft Zone 1 and 20-ft Zone 2, with impact locations and overall buffer impact total remaining the same. D. Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project.* Impacts to jurisdictional features have been avoided and minimized to the maximum extent practicable by incorporating resourceful site planning, including the utilization of the wetland delineation to adjust the layout to avoid and minimize impacts. Avoidance and minimization measures were also accomplished during the design phase of the project. The Applicant has avoided and minimized impacts to the greatest extent practicable given the goal of the project and the purpose and need. The proposed impacts are required in order for the project's goals to be realized. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Rather than permit the existing culvert the Applicant has elected to remove the road crossing and return the stream area to its natural state and function. Proper sedimentation and erosion control methods will be utilized during all phases of construction and installation as described in accordance with the requirements of the North Carolina Department of Environment and Natural Resources: Erosion Control Planning and Design Manual (May 2013) and local codes. All work will take place during dry conditions and can be facilitated from high, non -jurisdictional, stable ground. The contractor shall install silt fence, inlet protection, sediment traps, diversion ditches, temporary coffer dams, tree protection, clearing only as necessary to install devices. All erosion and sediment control measures will be checked for stability and operation following every runoff producing rainfall, but in no case less than once every week. Any needed repairs will be made immediately to maintain all measures designed. An erosion control inspections report is required and will be kept by the owner's representative. Temporary seeding and permanent seeding plans are included to restore impacted areas. The project will meet all relative requirements of Best Management Practices and Engineered Stormwater Control Structures as outlined through State and Local Stormwater Rules. Measures will be taken to prevent oil, tar, trash, debris and other pollutants from entering the adjacent jurisdictional features. Any excess excavated materials not utilized as back fill will be placed and contained within upland areas and permanently stabilized to prevent erosion into adjacent jurisdictional features. Therefore, stockpiling of excavated material within jurisdictional waters of the U.S. will be strictly prohibited as part of the construction of this project. All project construction activities initiated within jurisdictional waters of the U.S. will be carried to completion in an expeditious manner to minimize the period of disturbance within the jurisdictional streams. E. Diffuse Flow Plan ^ .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 1a. What type of SCM are you providing?* ® Level Spreader ❑ Vegetated Conveyance (lower SHWT) ❑ Wetland Swale (higher SHWT) r Proposed project will not create concentrated stormwater flow through the buffer 17 Other SCM that removed minimum of 30% nitrogen 1b. Describe how diffuse flow will be maintained:* The proposed development is located within the Neuse River Basin and will be subject to the stormwater management requirements set forth in Article 8 of the Durham County Unified Development Ordinance (UDO). Durham County is within a water supply watershed. Stormwater management on this site shall address two primary issues: (1) peak discharge rates and (2) water quality management. The proposed stormwater management plan will be designed to protect the downstream environment. The plan incorporates biologically based stormwater management techniques to manage both water quantity and quality aspects of site runoff. Stormwater management will be accomplished by incorporating engineered SCMs throughout the project to capture and treat the stormwater runoff from developed areas. The proposed project will result in an increase in peak flow rates. To mitigate for this, three (3) stormwater wet ponds are proposed and have been sized such that post -development peak flow rates are no greater than pre -development levels in the 1-, 2-, 10-, and 100-year storm events. The stormwater management plan contains pre- and post -development nitrogen calculations. With regard to TSS removal, the SCMs have been sized for 85% TSS removal efficiency to provide TSS removal to the greatest extent possible. In addition, the Total Maximum Daily Load of fecal coliform is reduced by the proposed SCMs. If the development on this tract is built in accordance with the proposed stormwater management plan, then the requirements set forth in the Durham County UDO will be met with the proposed SCMs. However, modifications to the proposed development may require that this analysis be revised. Some modifications that would require this analysis to be revised include: 1) the proposed site impervious surface exceeds the amount accounted for in the stormwater management plan and 2) the post -development watershed breaks change significantly from those used to prepare this report. 1c.
