4. Project Description and History
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 general land use trend in the watershed of the project area and in Greenwood Park itself has been gradual urbanization. The watershed has transitioned from wooded land to
wooded lowidensity residential development with more impervious/commercial development infilling along Highway 25/Hendersonville Road. Currently the buffer consists of turf grass
and shade trees. Stormwater is conveyed to via overland flow with some channelization, and three direct pipes. There is minimal treatment of stormwater as it flows directly to the stream
or over turf grass. These conditions preclude the ability of the stream and riparian corridor to moderate temperatures, filter pollutants from runoff, recharge groundwater, mitigate peak
flows, and provide habitat.
The attached Engineering Report and Environmental Information Document includes detailed information regarding existing conditions and proposed conditions.
4b. Have Corps permits or DWR certifications been obtained for this project (including all prior phases) in the past?*
r Yes r No r Unknown

4f. List the total estimated acreage of all existing wetlands on the property:
4g. List the total estimated linear feet of all existing streams on the property:
344
4h. Explain the purpose of the proposed project:*
The purpose of this Project is to restore the natural stream and improve the riparian corridor functions of a firstlorder stream located in Greenwood Park in the Town of Biltmore Forest.
Urbanization of the watershed has caused erosion of the banks, which was mitigated by installation of wire gabion baskets in 1991. However, the baskets have reached the end of their
service life and erosion is occurring. The failing baskets also present a safety hazard to the public, as the project is located in a public park where access to the stream is readily
available. The Project will restore approximately 350 linear feet of a firstlorder unnamed tributary (UT) to the Fourmile Branch and approximately 0.6 acres of the riparian corridor is
proposed. Urbanization of the approximate 0.3 square mile watershed and impacts to the riparian corridor have degraded the stream.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The proposed restoration will include removal of approximately 570 linear feet of existing wire gabion baskets and reuse of the rock and soil inside the baskets to reshape the banks.
Native trees and shrubs will be planted to repair the riparian buffer, further stabilize the banks, and provide other ecosystem services such as shading. In critical locations boulder toes,
soil lifts, or other bioengineered systems will be installed for additional armoring. In approximately 3 locations, grade control measures will be installed to provide for future watershed
conditions and to establish pools. This will establish a more natural stream bed, create the opportunity to flush the fine sediments that have accumulated due to soil erosion through the
system, and prevent stream incision which is commonly observed in many urban streams in North Carolina.
The project will be constructed using equipment that would be typical to stream restorations such as tracked backhoes and dump trucks. Some grading and filling will occur to create a
more naturalized channel. Stream flow may also be diverted (within the channel) during construction to mitigate sedimentation impacts downstream if only banks will be impacted that
location, for example.
4j. Please upload project drawings for the proposed project.

5. Jurisdictional Determinations
5a. Have the wetlands or streams been delineated on the property or proposed impact areas?*
r Yes
r No
Comments:
The project site was delineated by WithersRavenel in February 2020. There are no wetlands within
the project area. The only jurisdictional feature is the stream proposed to be restored. An Upland
Data Form have been provided in support of the delineation to document the lack of wetlands. We
are not requesting issuance of a Preliminary JD in conjunction with issuance of the NWP 27

E. Impact Justification and Mitigation C^U
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The stream restoration approach seeks to avoid most temporary impacts to the stream bottom. The primary restoration will consist of the removal of
gabion baskets that are or are just beyond the stream banks.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Construction access will be provided from both sides to avoid the need for construction equipment to cross the stream. A pump around system with
sediment filter bags will also be used to reduce sediment and turbidity.
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?
r Yes r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
The proposed project consists of restoration of the channelized stream and all proposed impacts will result in a functional uplift to the stream and therefore mitigation is not proposed.
F. Stormwater Management and Diffuse Flow Plan (required by DWR) u
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?

RE. Biltmore Forest - Greenwood Park Stream Restoration, 09190438.00
Dear Troy Beasley.
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached `Documented Occurrences' tables and map.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is documented within the project area or indicated within a one -mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Land and Water Fund
easement, or an occurrence of a Federally -listed species is documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rodnev.butlerWncdcr.aov or 919-707-8603.
Sincerely,

No Element Occurrences are Documented within the Project Area
There are no documented element occurrences (of medium to very high accuracy) that intersect with the project area. Please note, however, that although the
NCNHP database does not show records for rare species within the project area, it does not necessarily mean that they are not present, it may simply mean that
the area has not been surveyed. The use of Natural Heritage Program data should not be substituted for actual field surveys if needed, particularly if the project
area contains suitable habitat for rare species. If rare species are found, the NCNHP would appreciate receiving this information so that we may update our
database.

Please give a brief project description below.*

The purpose of this Project is to restore the natural stream and improve
the riparian corridor functions of a firstlorder stream located in Greenwood
Park in the Town of Biltmore Forest. Urbanization of the watershed has
caused erosion of the banks, which was mitigated by installation of wire
gabion baskets in 1991. However, the baskets have reached the end of
their service life and erosion is occurring. The failing baskets also present
a safety hazard to the public, as the project is located in a public park
where access to the stream is readily available. The Project will restore
approximately 350 linear feet of a firstlorder unnamed tributary (UT) to the
Fourmile Branch and approximately 0.6 acres of the riparian corridor is
proposed. Urbanization of the approximate 0.3 square mile watershed and
impacts to the riparian corridor have degraded the stream.
The proposed restoration will include removal of approximately 570 linear
feet of existing wire gabion baskets and reuse of the rock and soil inside
the baskets to reshape the banks. Native trees and shrubs will be planted
to repair the riparian buffer, further stabilize the banks, and provide other
ecosystem services such as shading. In critical locations boulder toes, soil
lifts, or other bioengineered systems will be installed for additional
armoring. In approximately 3 locations, grade control measures will be
installed to provide for future watershed conditions and to establish pools.
This will establish a more natural stream bed, create the opportunity to
flush the fine sediments that have accumulated due to soil erosion through
the system, and prevent stream incision which is commonly observed in
many urban streams in North Carolina.
The project will be constructed using equipment that would be typical to
stream restorations such as tracked backhoes and dump trucks. Some
grading and filling will occur to create a more naturalized channel. Stream
flow may also be diverted (within the channel) during construction to
mitigate sedimentation impacts downstream if only banks will be impacted
that location, for example.
Please give a couple of dates you are available for a meeting.
