The streambank in this location has been severely eroded and has resulted in the closure of the greenway for safety reasons. As described in the attached application, we plan to install various streambank stabilization and in -channel devices along 160 feet of Richland Creek to address erosion issues. Planned measures include bankfull bench enhancement, single arm vanes, geolifts, stone toe protection, bank sloping and rock stabilization. There will be about 2,000 square feet of unavoidable impact to Zone 1 of the stream buffer to conduct this activity. Once the site is stabilized, we plan to replant this area in native woody species in the next appropriate season. If you have any questions about this project or would like to conduct a site visit, please feel free to call me at 919-522-6364 or contact me via email at idornev@moffattnichol.com. Thank you in advance for your careful consideration of this request.

Page 7 of 16 D. Impact Justification and Mitigation 1. Avoidance and Minimization 1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The proposed project is the Least Damaging Practical Alternative that will stabilize the eroding streambank and allow the greenway to reopen. Two other alternatives were considered that resulted in more channel and streambank impact and would move the channel further away from the greenway but both were rejected since their stream and buffer impacts were greater and costs were higher. b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Work has been designed to have a minimal impact on the streambank in terms of grading and installation of structures in the stream channel itself and still accomplish the goal of stabilizing the streambank. Construction will be done from the greenway where possible to minimize impacts on the channel. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.
