Property size: 6.6 State / Province / legion NC Country USA 4a. 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 is located near the outskirts of a highly developed residential neighborhood. Hominy Creek flows along the eastern property boundary and is suffering from bank erosion that appears to be due in part to the effects of a remnant dam foundation that are directing flowtoward the left bank. The subject property is used as a church and includes two buildings, a paved parking lot and a grass overflow parking area. 4b.

List the total estimated linear feet of all existing streams on the property: 970 4h. Explain the purpose of the proposed project:* The purpose of the project is to stabilize the and protect the eroding stream bank. 4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:* The stabilization practices include stone toe reinforcement to protect the lower bank, boulder vanes to direct flow energy away from the eroding bank, and reinforced soil lifts ("geolifts") with dormant cuttings of native riparian species on the upper bank. The cuttings in the soil lifts will quickly establish a stabilizing root mass while also providing shade to the stream. The wooden foundation remains of a dam that was removed decades ago will remain in place, with the upstream of the two vanes butting against the downstream side of the structure. Equipment will include track -mounted excavators, dump trucks and hand tools. 4j. Please upload project drawings for the proposed project. Hominy Stabilization Plans CSL 081919.pdf 15.45MB 5.

Total stream and ditch impacts: 770 3j. Comments 31 E. Impact Justification and Mitigation -- 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project: The proposed stabilization measures are based on a natural channel design approach and avoid hard armoring the bank. Much of the work can be performed from the top of bank, but some equipment access to the stream will be required. Coir fiber matting will be used to stabilize disturbed bank soils. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques: All construction equipment and materials (stone, seed and coir matting) will be mobilized to the site before work begins. Equipment will be maintained to be free of leaks and fueling will be performed well away from the stream. The base flow is too large to use apump-around flow diversion, but work Wil be staged during times of lowflow in order to minimize downstream turbidity impacts. Work will be staged such that no more stream bank and bed is disturbed than can be fully stabilized by the end of that work day. 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? l' Yes F No 2b. If this project DOES NOT require Compensatory Mitigation, explain why: The work being proposed will improve and protect aquatic resources. F. Stormwater Management and Diffuse Flow Plan (required by DWR) 1. Diffuse Flow Plan 1a. Does the project include or is it adjacent toprotected riparian buffers identified within one of the NC Riparian Buffer Protection Rules? r Yes r No If no, explain why: Site is not located in a buffer protection area. 2. Stormwater Management Plan 2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?* r Yes r No 2b. Does this project meet the requirements for low density projects as defined in 15A NCAC 02H .1003(2)? r Yes r No Comments: Work will not result in an increase in impervious surface. G. Supplementary Information 1. Environmental Documentation 1a. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land?* r Yes r No 2. Violations (DWR Requirement) 2a. Is the site in violation of DWR Water Quality Certification Rules (15A NCAC 2H .0500), Isolated Wetland Rules (15A NCAC 2H.1300), or DWR Surface Water or Wetland Standards or Riparian Buffer Rules (15A NCAC 2B.0200)?* r Yes r No 3. Cumulative Impacts (DWR Requirement) 3a. Will this project result in additional development, which could impact nearby downstream water quality?* r Yes r No 3b. If you answered "no," provide a short narrative description. The project is focused on stabiliang the eroding bank and protecting emsting upland areas. 4. Sewage Disposal (DWR Requirement) 4a. Is sewage disposal required by DWR for this project?* r Yes r No r N/A 5. Endangered Species and Designated Critical Habitat (Corps Requirement) 5a. Will this project occur in or near an area with federally protected species or habitat?* r Yes r No 5b. Have you checked with the USFWS concerning Endangered Species Act impacts?* r Yes r No 5d. Is another Federal agency involved?* r Yes r No r Unknown 5e. Is this a DOT project located within Division's 1-8? r Yes r No 5f. Will you cut any trees in order to conduct the work in waters of the U.S.? r Yes r No 5g. Does this project involve bridge maintenance or removal? r Yes r No 5h. Does this project involve the construction/installation of a wind turbine(s)?* r Yes r No 5i. Does this project involve (1) blasting, and/or (2) other percussive activities that will be conducted by machines, such as jackhammers, mechanized pile drivers, etc.? r Yes r No 5j. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? USFWS website was the primary source. Endangered species likely exist in this part of Buncombe County, but the work will be confined to a narrow corridor along Hominy Creek that was cleared and developed many years ago .
