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 in an agricultural area south of the Town of Clyde. Current land use is primary hay field. The adjoining property is used intermittently for pasture. The stream appears to
have been straightened and moved away from the low point of the valley in order to promote agricultural uses. Buffers are limited and bank erosion is an ongoing problem. Two culverts
are present on the stream, one of which was damaged during floods in 2021.

4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past? *
Yes No Unknown
4f. List the total estimated acreage of all existing wetlands on the property:
3
4g. List the total estimated linear feet of all existing streams on the property:
3300
4h. Explain the purpose of the proposed project:*
The purpose of the project is to restore the stream in order to promote long term stability and improve the aesthetics of the stream corridor. Flooding in 2021 destroyed the two culverts that
were used to cross the stream and access the eastern portions of the property. The downstream culvert has been repaired but the upstream culvert remains damaged and unusable. Bank
erosion has been an eyesore for the landowners.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The proposed restoration is depicted on the attached preliminary plans. The reach measures about 3020 linear feet, beginning at the upstream property line at Stamey Cove Road and
extending to the downstream property line. Restoration over the downstream 2500 LF will occur mainly off-line, with the stream being relocated to the low point of the valley and away from
high eroding banks. A sequence of tortuous bends near the downstream property line will be re-routed to a more stable plan form. The upstream 600 LF reach will be stabilized and
enhanced mainly on-line. Riparian buffers will be improved with native species of live stakes, bare root seedlings and some containerized stock. Buffer widths will vary from about 15 feet
to over 50 feet.
Conventional earthwork equipment will be used, including track -mounted excavators, off -road dump trucks, pumps and hand tools. Impacts will be kept to a minimum by staging work
during periods of low flow and taking measures to limit equipment in the stream.
5. Jurisdictional Determinations
5a. Have the wetlands or streams been delineated on the property or proposed impact areas?*
Yes No
Comments:
5b. If the Corps made a jurisdictional determination, what type of determination was made? *

3j. Comments:
Wetlands adjacent to the stream restoration may be temporarily impacted by construction but will be improved over the long term with the restoration
work by raising the channel and groundwater levels, as well as improvements to vegetative buffers.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Restoration design used a natural channel design approach which seeks to create dynamic equilibrium between the stream and it's watershed. The
restored channel will have vastly improved bed form diversity, floodplain access and riparian buffers. The off-line restoration earthwork will allow
baseflow to remain in the original channel, which should limit sediment impacts during construction.
lb. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
For on-line reaches, equipment will work from the top of bank as much as practical. A pump -around will be employed in areas where prolonged
equipment access to the stream is necessary. The majority of the earthwork will be performed off-line with equipment operating well away from the live
stream. Silt fences will be installed on the stream side of any stockpiles. Work will be staged during periods of low flow and disturbed ground will be
stabilized with seed, mulch and matting upon reaching final grades. The contractor will limit bank disturbance to those areas that can be stabilized by the
end of each workday.
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 - No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
The project will be a net benefit to natural resources and is not considered development.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan
la. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
Yes No
If no, explain why:
The project will not result in any new impervious surfaces.
2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250? *
Yes No
2b. Does this project meet the requirements for low density projects as defined in 15A NCAC 02H .1003(2)?
Yes No
Comments:
A Stormwater management plan is not required for this stream restoration project.
G. Supplementary Information
1. Environmental Documentation
la. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? *
Yes 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)?*
Yes No
3. Cumulative Impacts (DWR Requirement)
3a. Will this project result in additional development, which could impact nearby downstream water quality?*
Yes No
3b. If you answered "no," provide a short narrative description.
This will be a discrete stream restoration project.
4. Sewage Disposal (DWR Requirement)

4a. Is sewage disposal required by DWR for this project?*
Yes No N/A
5. Endangered Species and Designated Critical Habitat (Corps Requirement)

Yes No
5g. Does this project involve bridge maintenance or removal?
Yes No
5h. Does this project involve the construction/installation of a wind turbine(s)?*
Yes 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.?
Yes No
5j. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat?
We consulted the USFWS website for species information and while several species are listed for Haywood County. Based on the limited scope of the
project and current impacted conditions at the site, we do no not believe impacts to endangered species or habitats will occur.
