The Shuford Project is proposed to create a commercial building in Hickory NC with minimal
impacts to Jurisdictional Waters of the US. The original grading plan has been modified to
' reduce piped impacts to UT-Miller Branch, a degraded perennial channel located in an industrial
watershed (see Shuford Site Photos). The initial plan for this site called for approximately 500
feet of stream impacts. In order to reduce the length of the proposed pipe the size of the
Page 5
1
proposed building was reduced to the maximum extent possible given the intended use Project
' viability currently relies on the proposed 265 ft of 66"CMP and associated fill to create the
developable commercial lot. The proposed project pipe (66"CMP) is to be installed below the
elevation of the streambed to allow low-flow passage of water and aquatic life
The goal of the project restoration is to convert UT-Miller Branch to a natural referenced stable
condition. To minimize impacts, the proposed channel will be constructed in the dry before tying
' in to UT-Miller Branch. To further reduce impacts immediately following construction all
disturbed riparian areas will be seeded with a temporary grass mix. Permanent re-vegetation of
riparian areas will follow, along with the use of erosion control matting to ensure bank stability
' (see Shuford Proiect Narrative).
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
' necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
' mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
' If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
' incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmg,ide.htm1.
' 1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
' of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
' a separate sheet if more space is needed.

Shuford Development Project
' 404/401 Permit Application
Project Narrative
' General:
The purpose of the project is to create a viable commercial development along SR 1003
(Tate Blvd.) in Hickory, NC. The project site is an 8+ acre lot that exists within an
industrial/commercial watershed. The proposed development will involve the construction
of two commercial office buildings and associated parking. Elevation on site is
' approximately 1000 feet above mean sea level. The project site contains two streams,
Miller Branch, and UT-Miller Branch, located within the Catawba River basin. UT-Miller
Branch (project reach) flows under Tate Blvd. and onto the project site via a 60" CMP. The
project's reach then flows south approx. 576 ft. before converging with Miller Branch, a
' Class-C stream flowing northwest to southeast along the southern border of the project
area. The project site is currently undeveloped with minimal impervious area but has been
cleared, partially filled, and graded.
The financial viability of the project relies on the piping of UT-Miller Branch to create a
developable commercial lot. The project reach exists as a degraded gully that flows from
' the existing 60"CMP (under Tate Blvd.) to Miller Branch with minimal pattern (Sinuosity
= 1.1). Priority 1 and 11 compensatory restoration is proposed to reroute the project reach
from the outlet of the proposed pipe across the gentle sloping valley of Miller Branch.
' Stream restoration design objectives are to restore and enhance aquatic habitat, create an
accessible floodplain to disperse channel energy, create stable grade control (reducing
vertical erosion) and establish dense, native riparian vegetation along the banks of UT-
Miller Branch.
Streams:
' UT-Miller branch is a steep, entrenched G5 (gully) channel with minimal riparian
vegetation and high erosion potential (see Existing Site Conditions & Morphological table).
The 90 +/- acre drainage area begins in an industrial park and virtually the entire system is
' piped under several large buildings and parking lots. Approximately 39 acres of the
watershed exists as impervious surfaces (commercial/industrial buildings, parking lots;
approx. 43% imperviousness). Currently, the project reach of UT-Miller Branch is severely
' incised and fully entrenched in most areas (Mean Entrenchment Ratio -1.3). The steep
banks of the upper reach (Sta 0+00-3+00) are sparsely vegetated and scattered with
abandoned construction materials (steel roofing, bricks, concrete). The banks of lower
' reach (Sta 3+00-5+76) are vegetated with woody vegetation yet show signs of lateral
erosion (vertical and undercut banks present). Bankfull widths along UT-Miller Branch
range from 9 to 19 feet. A large head-cut exists at approx. Sta 3+20 in which the channel
falls approx. 4+ ft into a deep pool scattered with broken asphalt and an oxidized iron pipe
(see Site Photos).
Waters flowing through this 1st order tributary (UT-Miller Branch) are typical to those
found in an industrial watershed. Red iron-oxide was found on the banks throughout the
project reach (indicator of hypoxic conditions) and a pungent odor was noted in the 1/29/04

stream assessment/classification. No benthic macro-invertebrates were found in the 1/29/04
' stream assessment. UT- Miller Branch is considered to be a poor quality stream (see
USACE Stream Quality Assessment worksheets & DWQ Stream Classification forms) and
is associated with a 1:1 compensatory mitigation ratio (see USACE/NCDWQ Stream
Mitigation Guidelines).
Miller Branch exists as a stressed, urban, E-type channel with a drainage area of 0.86 sq mi
' (550.6 ac). The channel flows northwest to southeast along the southern boundary of the
project site with a bankfull width of approx. 20 feet. Miller Branch is designated as Class-C
waters.
No wetlands exist within the project area.
' Proposed Impacts:
The proposed project will involve impacts to regulated Waters of the United States and will
require a Section 404 permit from the US Army Corps of Engineers (USACE) and a
' Section 401 permit from NC Division of Water Quality (DWQ). To create a developable
commercial lot adjacent to Tate Blvd., approx. 265 linear feet of UT-Miller Branch is
proposed to be piped via a 66"CMP. The remainder of the project impacts will be
' associated with the compensatory mitigation stream restoration, which is to pick up at the
outlet of the proposed pipe. Cumulative impacts include 265 feet of pipe, 14 linear feet of
priority 2 restoration (restoring existing channel), and approximately 20 linear feet of fill
' needed to plug the lower channel. Total proposed impacts are approx. 299 linear-feet to
Jurisdictional Waters of the US.
' Avoidance and Minimization:
Design modifications have been made to the original grading plan to minimize impacts to
UT-Miller Branch. Currently, project viability relies on the proposed 265 feet of 66"CMP
' and associated fill to create a developable commercial lot along Tate Blvd. The proposed
pipe will be installed below the elevation of the streambed to allow low-flow passage of
water and aquatic life. To reduce project impacts, the grading and construction of the
proposed/relocated channel will be performed in the dry. Once the relocated and restored
channel is constructed and stabilized, UT-Miller Branch will be turned into the new
channel and the abandoned channel will be plugged, leaving the lower 100' of channel un-
filled. Immediately following construction, all disturbed riparian areas are to be seeded
with a temporary grass mix and covered with erosion control matting to ensure bank
stability. Once project construction has ceased, all riparian areas (approx. 50 ft total width)
' will be planted with a combination of native trees, shrubs, and a native floodplain seed mix
(see Vegetation Plan).
Mitigation:
' Approximately 390 linear-feet of priority I stream restoration/mitigation is proposed on
UT-Miller Branch, a degraded perennial channel located in an industrial watershed. The
primary goal of the compensatory mitigation is to facilitate the development of the
' proposed commercial property while creating a natural, stable channel to carry expected
flows and provide enhancement to the natural system. All stream channel restoration will
Shuford Project
Narrative 2 2/18/2008

be conducted in accordance with the NC Division of Water Quality's Stream Mitigation
' Guidelines and will be protected through a conservation easement or deed restrictions
prohibiting fill or any alterations to the channel.
' The proposed priority I restoration will commence at the toe of the steep-type 11 valley (at
invert of proposed 66"CMP) redirecting UT-Miller Branch across the gently sloping-type
VIII valley of Miller Branch (see Valley Type Map). The designed E5 channel is proposed
to flow approximately 390 linear ft down the well-developed floodplain/terrace of Miller
Branch (see Morphological table). Reference reaches were chosen for the proposed channel
based on morphological similarities/relationships such as valley type, stream type, and
' impervious area (see Morphological table).
The proposed stream restoration will be performed in accordance with Natural Channel
Design Parameters. To control grade, cross-vanes will be used to create and maintain
correct riffle-pool sequencing in accordance with reference reach parameters (see typical
detail). Root wads and J-hook vanes will be installed to minimize erosion and scour
potential and enhance in-stream habitat (see typical details). All in-stream rock-structures
will be composed of materials considered immovable by this flashy, urban watershed (see
pebble count). Floodplain and buffer zones will be protected from possibility chute cut-
offs and secondary channel formation through the use of sill rocks and logs installed
subsurface and perpendicular to anticipated flow. Typical grading equipment such as a
track-hoe and a dozer will be used to construct the designed channel and floodplain.
' Vegetation Plan:
The riparian zone and buffer areas will be re-vegetated with a combination of trees, shrubs
' and herbs/grasses. All disturbed areas will be sowed with a temporary grass mixture
(perennial/annual ryegrass) immediately following completion of the work in those areas.
Following construction, the banks of the restored channel will be sowed with a native
' floodplain seed mix and lined with erosion control matting to ensure bank stability and to
aid in the establishment of herbaceous vegetation. Native shrub and tree species will also
be planted throughout the project reach at a rate of 320 stems/acre, providing future
shading to the channel. Shrubs/Trees to be planted may include: Black Cherry, Green Ash,
Red Maple, Red Oak, River Birch, Silky Willow, Sycamore, Silky Dogwood, Tag Alder,
and Yellow Poplar (listed species are subject to change due to availability at local nurseries
' and forestry suppliers). The proposed undisturbed, vegetated buffer width will extend an
average of 25 feet from the top of bank on each side of the proposed channel (see
Vegetation plan).
' Stormwater Management:
Stormwater runoff from the proposed commercial/industrial site will be treated in wet
ponds designed and constructed in accordance with current NC DWQ guidelines (see
' stormwater management plan).
Erosion Control:
The erosion control sequence and measures will be designed in accordance with the NC
DENR Division of Land Quality. Silt fences will be installed downslope of all ground

disturbing activities reducing sediment contribution to the system. All disturbed areas will
' be hydro-seeded immediately following project grading/construction. Proposed stormwater
management ponds will be used as temporary sediment ponds during construction.

The following physical and biological monitoring is proposed in accordance with Clean
Water Act 401 Stream Mitigation Guidelines to determine the degree of success the project
will achieve in meeting stream stability objectives.

(Outlined in NC DENR Interim, Internal Technical Guide - Benthic
' Macroinvertebrate Monitoring Protocols for Compensatory Stream
Restoration Projects) will be used in collecting and evaluating all
samples required by this plan. Benthos collections will be performed
by DWQ certified personnel and a DWQ certified lab will be used to
evaluate all samples.
b. Samples will be collected from the proposed restoration reach prior
' to construction. A reference sampling site will be identified in the sub-
basin that will remain in a "pristine" watershed for the remainder of
the monitoring period.
' c. A 1-year adjustment period is proposed to allow macro-benthos
populations to re-colonize in the Restored reach.
d. Following completion of proposed work, samples will be collected at
' Restored and Reference sites in years 2, 3, and 4. All sampling sites
will be shown on the As-Built plan to be submitted following
construction.
' e. DWQ Stream Habitat Evaluation Forms will be provided each
monitoring year for the Restored and Reference reaches.
2. The following monitoring plan for plant survival is proposed:
a. The total number and location (by zone) of trees/shrubs planted in the
riparian easement will be recorded in the As-Built plan to be submitted
to DWQ upon project completion.
' b. Trees/shrubs will be counted in years 2, 3, and 4 following
construction and survival rate will be calculated for each species
reported.
' 3. Channel stability will be monitored according to the following plan:
a. An As-Built plan will be prepared and submitted following completion
' of the project restoration. This plan will consist of a complete "level 2"
analysis of the relocated stream providing dimension, pattern, and
profile information.
' b. Permanent/monument cross-sections will be established at a minimum
of two locations (a riffle and a pool section) within the Restored reach.

Narrative 4 2/18/2008
c. Stream physical assessment will be performed in years 2, 3, and 4
following project completion.
A report of findings will be submitted to DWQ/Wetlands Unit within 60 days following
survey completion.

Stormwater Management Plan
05-tq'18 03
Pre-development there are no existing impervious surfaces for this site. Based on the
proposed development plans the following calculations for two wet detention basin are
designed for at least 85% TSS removal for the applicable proposed impervious surfaces.
The basins are designed to treat runoff from the ultimate build-out, no stormwater will be
treated from off-site, the roads around the site are curb and gutter and do not discharge
runoff onto this site. The developed site will have a total impervious cover of 139,827
square feet, with total drainage to the designed basins being 311,606 square feet.
The West Basin will treat water from the West Drainage; this water will be
collected through pipes under the parking lot to collect parking lot and roof top
runoff. This runoff will be directed to a single pipe and directed to the West
Stormwater Basin. Stormwater West Basin was calculated with 85% TSS
removal. The wet detention basin will be supplemented with a level spreader and
a 30' wide vegetated filter. There is at least a 30' vegetative buffer between this
basin and any live streams. The anticipated seasonal high water table for this
basin at approximately 930 ft above sea level.

The East Basin will collect water from the East Drainage; this water will be pulled
from rooftop and parking lot though pipes and collectively directed to the East
Stormwater Basin. Stormwater East Basin was calculate with 90% TSS removal
because of space limitations, therefore, no level spreader or 30' vegetated filter
are required for this BMP. However, to prevent erosion of high flow events, the
outflow will go through a vegetative swale. There is at least a 30' vegetative
buffer between this basin and any live streams. The anticipated seasonal high
water table for this basin is at approximately 926 ft above sea level.

The calculations and design criteria were achieved using the "Stormwater Best
Management Practices Manual" compiled by NCDENR Division of Water Quality
(2007) and the Wet Detention Basin Supplement as designed by NC DWQ.
The designed wet detention basins will be used as sediment basins during construction.
After construction all sediment deposited during construction will be removed, erosional
features will be repaired, and the sizing, slopes, and depths will be restored as designed in
this stormwater management plan.

Wet Detention Basin Inspection and Maintenance Agreement

I will keep a maintenance record on this BMP. This maintenance record will be kept in a
' log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
t
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.

This system (check one):
® does ? does not incorporate a vegetated filter at the outlet.
'
This system (check one):
? does ® does not incorporate pretreatment other than a forebay.
'
Important maintenance procedures:
- Immediately after the wet detention basin is established, the plants on the
' vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
- No portion of the wet detention pond should be fertilized after the first initial
' fertilization that is required to establish the plants on the vegetated shelf.
- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
t - If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
' - Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of inspection and maintenance should be kept in a known set
location and must be available upon request.

Wet Detention Basin Inspection and Maintenance Agreement

I will keep a maintenance record on this BMP. This maintenance record will be kept in a
' log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
'
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
'
This system (check one):
? does ® does not incorporate a vegetated filter at the outlet.
' * calculated for 90% TSS Removal
This system (check one):
? does ® does not incorporate pretreatment other than a forebay.
'
important maintenance procedures:
- Immediately after the wet detention basin is established, the plants on the
' vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
- No portion of the wet detention pond should be fertilized after the first initial
' fertilization that is required to establish the plants on the vegetated shelf.
- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
' - If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
' - Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
' within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of inspection and maintenance should be kept in a known set
location and must be available upon request.

Vegetation Plan
Page 29 of 34
Vegetation Plan:
A uniform mix of topsoil will be brought in from off-site by one of the local soil
distribution companies listed on the plant schedule. It will be tested prior to use for the
appropriate pH, texture, nutrients, and content. Soils should have greater than 10% of
clay content for the wet detention basin. It will have a minimum of 5% organic content,
and a pH between 5.5 and 7.
All construction material will be removed before soils are placed within the BMP. The
' soils will be compacted at the bottom of the basin to create an impermeable barrier
between the new topsoil and the existing native soils.
r
Plants will be brought in from one of the local nurseries listed on the plant schedule.
Depending on seasonality some plants may not be available; changes made to the plant
schedule must be done by the engineer. Plants will be planted in clumps rather than
individually. The following table breaks down the amount of planting materials needed.
SW- West SW- East
Minimum number of

Planting Clumps 300 180
Minimum # of

Individual Plants 1050 625
Plants will be spaced at an average width of 8.5' and a minimum width of 6'. Random
' spacing is encouraged to allow for a more natural look. A wet pond seed mix will be used
to stabilize all zones; it will be applied as instructed by the supplier.
After initial planting there should be an immediate watering to keep the plants from going
into shock from being transplanted. Fertilizers may be incorporated into the initial
planting but should be avoided after that time.
Plants must survive at a rate of 90% after two years to be considered successful. At the
end of the first year staking from the live stakes will be removed, and all plants that did
not survive must be replaced. Any invasive weeds should be removed immediately. Re-
staking, watering, and protective tubing should be used to maximize plant survival where
necessary.
