Project Narrative
The project site is located at 3311 Webster Road in Sylva, North Carolina in Jackson County.
The proposed project consists of a reliability upgrade of existing electrical equipment,
replacement of storm drainage structures and pipes, and the new construction of a control
enclosure for the site. The site is identified by Jackson County GIS as Parcel Identification
Number (PIN) 7630-46-3425 and is located within the Webster Town ETJ. There is no existing
zoning assigned to the parcel according to Jackson County GIS.
Existing access is provided by a gravel access drive from Webster Road leading down into the
site. The site is lower in elevation to Webster Road and adjacent to an unnamed ephemeral
stream that feeds directly into Savannah Creek, approximately 200 linear feet South of the site.
The unnamed stream is not located on USGS Quadrangle maps; however, from site inspections
and due to the direct discharge to Savannah Creek it is being considered a protected
watercourse. All work within the stream will require a 404 permit with USACOE and a 401
permit with NCDWR. The unnamed stream also is protected trout waters and requires a 25-foot
trout buffer from the top -of -bank along the site. Due to the age of the substation, many features
predate the trout buffer regulations and are currently located within the 25-foot buffer. Due to the
new control enclosure and associated site work for the reliability upgrades, a trout buffer waiver
is being requested for the project.
Proposed Disturbance Activity
The proposed project consists of replacing oil filled equipment with gas equipment, replacing
aged equipment and replacing the control enclosure. Light grading is required within the trout
buffer limits to provide the subgrade elevation for the new control enclosure. All grading activity
within the buffer will be allowed to April 16th thru October 14th. Additional light grading is required
for storm structure replacement and new equipment areas outside of the trout buffer limits.
Excavation for storm pipes and new foundations are proposed, along with demolishing of
outdated foundations. Temporary stockpile areas have been identified onsite to accommodate
excavated material from the above -mentioned work. All excess soil and debris will be removed
from the site and hauled to a NCDENR permitted facility. The existing gravel drive outside of the
substation fence will be dressed in a new 6-inch layer of ABC crusher run, for equipment
deliveries and construction traffic use (Trout Buffer Impact Exhibit, Appendix A).
The project will consist of two phases for the storm drainage improvements, with the largest
impact to the Trout Buffer occurring in Phase 2. Due to project timeframe and permitting
complexity, all internal storm drainage pipe will be replaced along with associated storm
structures as part of phase 1 and as indicated on the plans (outside the Trout Buffer limits). This
is to ensure that all equipment is protected in the event of an oil spill and runoff from the site is
adequately collected and detained prior to entering the stream.
Phase 2 will consist of rerouting and replacing the oil containment pit outlet pipe from the outlet
control structure to the outfall. The rerouting is required for future maintenance purposes of the
storm drainage structure and the proximity of the new control enclosure. The new outfall will be
located along bank of unnamed stream bank and will require a temporary bypass pump around
for the work. To complete the relocation work a 404 USACE and 401 NCDWR permit are
required and shall be obtained prior to phase 2 plans being submitted for erosion control
permitting. Below is a bullet outline of Trout Buffer impacts occurring in the two phases
throughout the project.

Phase 1 — Anticipated Trout Buffer Impact
Excavation and grading for new control enclosure slab — Priority item for construction
timeframe and occurs first.
Additional ABC crusher run added to existing access loop around the station —
completed early in construction for vehicular use — lifts to be compacted to 98% density
Temporary stock pile of soil material along the South East fence line of the station —
stockpile may be used in the event additional area is needed outside of stockpile areas
to the North onsite — excess material is expected to be produced from new foundations
being installed.
Phase 2 — Anticipated Trout Buffer Impact
• Installation of impervious berms upstream and downstream of proposed storm outfall
location, along with silt fence.
• Installation of stilling basins, bypass pumps, hoses, and outlet protection for stream
bypass pump around.
• Excavation along unnamed stream bank to install new headwall and 18-inch HDPE pipe
for oil containment pit — anticipated to be the largest impact to the trout buffer — Storm
drainage system modification are designed for construction to completed 75% of the
work outside of the trout buffer with the last 25% being held until a period of dry and
stable weather.
• Work completed on the last run of 18-inch HDPE for the storm system shall be
completed within one (1) working day by use of HDPE pipe material and precast
concrete headwall structure.
• Existing outlet pipe shall be abandoned in place, plugged at the outfall and remainder
filled with flowable fill material.
• Riparian buffer for the unnamed stream shall be repaired according to the riparian buffer
planting details included on the design plan for Phase 2 work.
Approximate Construction Schedule (Land Disturbing Activities)
March 1st, 2021— Pre -construction meeting held for phase 1 work to commence per with
NCDENR and project Stakeholders.
March 151h, 2021— Installation of erosion control measures per the approved plan.
April 1st, 2021— excavation and replacement of existing storm drainage internal of the site —
outside trout buffer limits.
April 161h, 2021— excavation and grading to commence for new control enclosure foundation.
May 171h, 2021— Complete new control enclosure foundation pour for 28-day curing.
June 11, 2021— USACE 404/DWR 401/Revision to Erosion Control plans are approved and in
hand for phase 2 storm drainage replacement work. Being installation of storm drainage system
outside of buffer area leaving work to be completed within one (1) working day for impact within
the stream and buffer. Install stream bypass pump around per the plan and details.

July 31st, 2021— Complete all storm drainage relocation work by this date. Remove stream
bypass pump around and repair/replant riprarian buffer per the approved plan. Completion of all
phase 2 work completed.

Guidelines for Riparian Buffer
Restoration
Department of Environment and Natural Resources
Division of Water Quality
Wetlands Restoration Program
Raleigh, NC
January 2001
Purpose of these Guidelines
Riparian buffers have been identified as a valuable tool for protection of water quality
when properly designed and established in the appropriate landscape setting. For this
reason, the goal of the North Carolina Wetlands Restoration Program (NCWRP) is to
implement projects to restore riparian buffers that have the greatest value for reducing
pollutants in our surface waters as well as provide important aquatic and wildlife habitat.
The purpose of these guidelines is to provide the technical information necessary for the
successful planning and establishment of riparian buffers. The guidelines are intended
for use by private consultants in developing restoration plans for the NCWRP but should
also have utility for private landowners as well as local governments involved in the
restoration of riparian buffers.

*'�
Criteria for Priority
Riparian Bufer Restoration Projects
A number of factors determine the
success of particular riparian buffer
restoration projects. In addition to the
physical characteristics of the site, issues
such as land costs, land ownership, and
logistical constraints must be taken into
consideration. The following physical
characteristics are intended to provide
general guidance when identifying sites
and are not intended to exclude sites that
may have merit based on other criteria.
• Woody vegetation absent or
sparse (less than 100 stems per
acre that are > 5 inches diameter
at breast height) measured within
50 feet of intermittent and
perennial streams, lakes, ponds,
and shorelines.
• Adjacent to headwater streams or
those streams defined as first,
second, or third order.
• Project length greater than 1,000
feet (for projects implemented by
the NCWRP).
• Ditches, gullies, or evidence of
concentrated flow within 50 feet
of intermittent and perennial
streams, lakes, ponds, and
estuaries.
• Adjacent source of nitrogen
including cropland, pasture, golf
course, residential development,
ball fields, etc.
• Water table depth within three to
four feet of surface as determined
by characteristics of soil cores.
i
Components ofa Riparian Buffer
Restoration/Enhancement Plan
Site Assessmei7t
The riparian area to be restored
should be evaluated with respect to these
factors that control the viability of
riparian plants:
• Soil moisture
• Soil pH
• Soil texture
• Seasonal high water table depth
• Flooding potential
• Aspect, topography, and
microtopographic relief
Site Pf-ePIf�tion
The restoration/enhancement plan
should address these items regarding
preparation of the site for planting:
• Plow or rip site to improve
compacted soil and/or eliminate
areas where channelized flow has
developed.
Control of sod -forming grasses
such as fescue and Kentucky
bluegrass that will compete with
plantings for nutrients.
Control of invasive, exotic plants
that would hinder the re-
establishment of woody
vegetation. Proposals for
pesticide use should always be
reviewed by the North Carolina
Division of Water Quality staff
to insure compliance with the
Neuse and Tar -Pamlico Riparian
Buffer Rules.

Common Invasive Exotic Plants
in North Carolina
Ailanthus altissima (Tree -of -Heaven)
Albizia julibrissin (Mimosa)
Elaeagnus umbellata (Autumn
Olive)
Hedera helix (English Ivy)
Lespedeza cuneata (Korean or
Sericea Lespedeza)
Ligustrum sinense (Chinese Privet)
Lonisera japonica (Japanese
Honeysuckle)
Microstegium vimineum (Japanese
Grass)
Paulownia tomentosa (Princess
Tree)
Pueraria lobata (Kudzu)
Rosa multiflora (Multiflora Rose)
Wisteria sinensis (Chinese Wisteria)
Stabilize areas of bare soil.
Refer to the following list for
species of grasses/sedge
appropriate for soil stabilization.
The majority of these species are
by necessity not native to North
Carolina. At present, there are
only a few species of native
grasses useful for erosion control
that are commercially available.
Please note that fescue grasses
should not be used for soil
stabilization. Fescue grasses,
particularly tall fescue, are
competitive and will inhibit the
eventual re-establishment of
native species.
Agf-os&5')1b') (Redtop)
Found in fields, pastures, roadsides,
and other disturbed places
throughout North Carolina, this
native warm season grass should be
used sparingly for erosion control
and soil stabilization.
C'If-ex (Sedge)
This sedge occurs naturally in
marshes and low meadows
throughout the mountains and
northern piedmont and coastal plain
of North Carolina. This species has
utility in a mix for soil stabilization
in moist areas.
)?Ic(ylisglomef�t) (Orchardgrass)
This perennial, cool season
bunchgrass is a good alternative to
fescue because it is less competitive
and allows native herbs to colonize
the site.
Hot -%um spp. (Barley)
A number of species of barley can be
used for soil stabilization. Barley is
a cool season, annual grass that when
moisture is available will germinate
in the fall, stay green during the
winter, and then die in the spring as
competition for warm season plants
increases.
P1171cum %17cfe5tiI7um (Deer
Tongue)
This native, perennial, warm season
bunchgrass can be used in moist low
woods primarily in the piedmont and
mountains.
Plnicum spp. (Panic Grasses)
A number of species of panic grasses
can be used for soil stabilization

depending on the moisture regime
and soils of the site.
RlOicum vifgItum (Switchgrass)
This native, perennial, warm season
bunchgrass can tolerate a wide range
of moisture regimes. It can be used
along streams, in wet or dry woods,
brackish and freshwater marshes,
sloughs, swales, and low pinelands
primarily in the eastern piedmont
and coastal plain.
Pe171715etum9bucum (Brown Top
or Pearl Millet)
This fast-growing, robust, annual
grass exhibits good drought tolerance
which makes this species an
important warm season option for
soil stabilization.
Ph,)1)H�5d,-uI7diI7dce,) (Reed
Canarygrass)
A native to North Carolina, this
perennial cool season grass is used
for the stabilization of pond
shorelines, drainage ditches, and
streambanks in the mountains and
western piedmont. It is established
by planting freshly cut stem slips or
rhizome fragments. Please note that
this species is aggressive and forms
large monotypic stands that displace
other species. It should only be used
if no other species are available.
Sec:lle cef-e'I/e (Wi nte r Rye or
Rye Grain)
Winter rye is a cold -hardy annual
grass that will germinate and grow at
low temperatures. By maturing
early, it offers less competition
during the late spring, a critical time
in the establishment of perennial
species. Winter rye germinates
quickly and is tolerant of poor soils.
Sorghum bico/o�CSudangrass)
Only the small -stemmed varieties of
this annual warm season grass
should be used. Sudangrass is useful
for temporary seeding, and it is
adapted to soils relatively high in
clay content. Seed for common
Sudangrass is not always available,
but other small -stemmed types may
be used, such as the hybrid Trudan.
The coarse -stemmed Sorghum-
Sudangrass hybrids are not
appropriate for erosion control.

RipIr1,10 Buff r De51g17
St ecies Diversity and Composition
The most effective riparian buffers
have trees and shrubs to provide
perennial root systems and long-term
nutrient storage. The design of a
riparian buffer can be modified to fit the
landscape and the landowner's needs, for
example, by replacing shrubs with more
trees, substituting some of the trees with
shrubs, or incorporating a grass zone. In
any scenario, the width of the woody
vegetation should be at least 30 feet
directly adjacent to the
streambank/shoreline.
Choose 10-12 species of native trees
and/or shrubs appropriate for site based
on site assessment and reference
conditions. In addition, please note that
this list is alphabetical and does not take
into account the assemblages of plants
Native Regions
M= Mountains
P= Piedmont
C= Coastal Plain
found in nature. The inventory of plants
found on the reference site can help
determine an appropriate assemblage for
the restoration site. In addition, the
North Carolina Natural Heritage
Program's Classification of the Natural
Communities of North Carolina: Third
Approximation is a valuable reference on
natural assemblages of plants (Shafele,
Michael P. and Alan S. Weakley, 1990).
Typically, there should be at least
three or four understory trees for every
canopy tree to provide structural
diversity similar to mature forests.
Where shrub species are incorporated
into the planting plan, they should be
distributed more densely at outer edge of
riparian buffer to reduce light
penetration and recolonization by
invasive exotic species. Refer to Table 1
for a list of native tree and shrub species
appropriate for use in riparian buffers.

* These species fix nitrogen and should not be used for riparian restoration adjacent to Nutrient Sensitive
Waters.
Where grasses are incorporated into the planting plan on the outside of the buffer strip,
only native grasses should be used. Native grasses produce a much more extensive and
deep root system than commonly used non-native grasses such as fescue.

Planting Density
Trees should be planted at a density
sufficient to provide 320 trees per acre at
maturity. To achieve this density,
approximately 436 (1Ox10 feet spacing)
to 681 (8x8 feet spacing) trees per acre
should be planted initially. Shrubs should
be planted at a density sufficient to
provide 1,200 shrubs per acre. Refer to
Table 2 for the number of trees and
shrubs per acre based on various methods
of spacing.

Plant Size
In many cases, the most cost effective
and successful size plant material is bare
root seedlings. Some species such as the
hickories do poorly as bare root
seedlings and will be much more
successful as containerized seedlings. In
either case, tree shelters should be used
to accelerate growth and increase
survivability of seedlings. In addition,
management of competing vegetation
after planting is easier, mowing and
weed wacker strikes are prevented,
herbicides are isolated from trunk
contact, and grazing by deer are
restricted. The use of tree shelters may
only be practical from an economic
standpoint for more expensive seedlings
of species difficult to establish, such as
red oak. Reductions in maintenance
costs and increased seedling vigor
associated with tree shelters suggest that
tree shelter plantings may be a more
cost-effective approach than planting
unprotected larger material. In urban or
other high visibility areas, some
specimen trees and shrubs should be
incorporated into the planting plan for
projects implemented by the NCWRP.
When live stakes or dormant cuttings
are incorporated in a planting plan,
choose only the previous season's
growth. Live stakes should typically be
approximately 3/4 inch in diameter and
three feet long, and dormant cuttings
should be approximately'/2 inch in
diameter and two feet long.

Sunliers of Native Plant Material
Local nurseries are the best option in acquiring plants that will be successful. Plants
grown from seeds or cuttings collected close to the restoration area will be the most likely
to survive and reproduce. The following is a list of nurseries that supply native plant
material. This list is not considered exhaustive or an endorsement by the NCWRP but
merely a source of potential vendors of native plants.

Planting Layout
The planting plan should indicate that
trees and shrubs will be planted in a
random pattern. For inexperienced
planting crews, pre -labeled flagged
wires can be used to mark the random
location of plantings. These flags can
also be color coded for each particular
species. Various colors of spray paint
can also be used to differentiate species.
Planting Practices
When planting seedlings, it is helpful
to mark the plants with colored flagging
to make them easier to locate during
maintenance tasks. The flagging can
also be color -coded to mark plants that
have died for replacement at a later date.
Tree protectors are also helpful for
locating plants.
Tree seedlings should be kept moist
and should not be exposed for extended
periods of time. A correctly planted tree
should have the following general
characteristics:
• Planted so that the root collar is
slightly below the soil surface.
• Have the main roots nearly
straight or spread out.
• Have soil firm around the roots.
• Have the tree in an upright
postion and have it nearly even
with the general ground level, not
sunk in a hole or raised on a
mound.

Please note that the Neuse and Tar -
Pamlico Riparian Buffer Rules allow for
a one time fertilizer application to
establish newly planted vegetation.
Ongoing fertilizer application is
prohibited by these rules.

Control of Grasses and Forbs
In the early stages of riparian buffer
establishment, competition for nutrients
by adjacent grasses and forbs will
substantially inhibit seedling growth.
Release from herbaceous competition
has been demonstrated as the most cost-
effective method to accelerate the
growth of seedlings. The plan for buffer
establishment must incorporate control
of the herbaceous layer. Options for
weed control include four to six inches
of well -aged hardwood mulch, weed
control fabrics, or pre -emergent
herbicide. Typically, mowing to control
weeds will be impractical based on the
random distribution of plantings. Weed
control should be continued for three
years from the time of planting.
Areas of Concentrated Flow
During the required five year
monitoring period, the riparian buffer
should be inspected for evidence of
concentrated flow. If concentrated flow
has begun to form, a level spreader or
other best management practice should
be installed to diffuse the flow before it
enters the restored riparian buffer.
