SUBJECT: APPROVAL of 401 Water Quality Certification with Additional Conditions
Samaritan's Purse Expansion
DWQ Project # 01 1075
Watauga County
Dear Applicant:
You have our approval, in accordance with the attached conditions (WQC #3287) and the
conditions listed below, to discharge fill into 240 linear feet of an unnamed tributary to East
Fork, Class WS-IV Waters, New River Basin, Watauga County for the purpose of expanding the
existing Administrative Building of the Samaritan's Purse facility. The activity must be
conducted as indicated in your application and Preliminary Grading, Drainage, and Erosion
Control Plan (Municipal Engineering Services Co., dated 6/26/01), received on July 12, 2001.
This approval is only for the impacts listed above and for the activities that you described
in your application and accompanying documentation received by the Division of Water Quality
on July 12, 2001. We have determined that General Water Quality Certification Number 3287
covers this fill activity. This Certification allows you to use Nationwide Permit Number 39
when issued by the US Army Corps of Engineers. Please keep in mind that there may be
additional Federal, State and Local regulations applicable to your project, such as the
Sedimentation and Pollution Control Act, Non-Discharge and Water Supply Watershed
Regulations, whereby you may be required to obtain permits and/or approvals prior to beginning
your project. In addition, this approval will expire when the accompanying 404 Permit expires
unless otherwise specified in the General Certification.
This approval. is only valid for the purposes and designs that you described in your
application. If you change your project, you must notify the Division in writing and you may be
required to submit a new application for a new Certification. If the property is sold, the new
owner must be given a copy of the Certifications and approval letter and is thereby responsible
for complying with all conditions. If total wetland fill for this project (now or in the future)
exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H

.0506(h). For this approval to be valid, you must follow the conditions listed in the attached
Certifications and the additional conditions listed below:
Plans for the stream channel relocation and restoration shall be submitted to and
approved in writing by this Office before impacts to waters, streams or wetlands occur. It
is recommended that the check list provided in Appendix F in NCDENR's The Internal
Technical Guide for Stream Work in North Carolina, May 2000, be used as a guide to the
types of design parameters that must be addressed in order to obtain plan approval.
2. Once DWQ approval is granted (as outlined in Condition 1), the stream restoration shall
be built according to the approved plans before the proposed Administration Building
Expansion on site is occupied. If the stream relocation becomes unstable, the stream
shall be repaired or stabilized using only natural channel design techniques. Rip-rap or
other hard structures may only be used as temporary repairs if required by the NC
Division of Land Resources or Delegated Local Program. Additionally, all repair designs
must be submitted to and receive written approval from this Office before the repair work
is performed.
3. Since 240 linear feet of the total stream restoration will be used as compensatory
mitigation for stream impacts, that portion (the restored channel plus the minimum 30
foot riparian buffers) shall be preserved in perpetuity through an easement or similar
legal mechanism. This easement or similar mechanism must be in place, and a copy
submitted to this Office, prior to occupation of the proposed Administration Building
Expansion.
4. The stream physical monitoring plan shall be implemented as described in your
application and reports must be submitted to this Office after the first year and every
other year afterwards for a total of five years.
5. The vegetation in the riparian area shall be maintained and/or replaced as necessary and
in accordance with the approved plan, to ensure a 5-year success rate of 320 trees per
acre.
6. As-built plans and the attached Certificate of Completion (COC) must be submitted to the
Division upon final construction of the relocated and restored channel.
7. An additional condition is that a final, written stormwater management plan shall be
approved in writing by the Division before impacts specified in this Certification can
occur. The stormwater management plan must include plans and specifications for
stormwater management facilities designed to remove 85% TSS according to the most

01 1075
Page 3
recent version of the NC DENR Stormwater Best Management Practices Manual. These
facilities must be designed to treat the runoff from the entire project, unless otherwise
explicitly approved by the Division of Water Quality. Also, before the Administration
Building Expansion is occupied at the subject location, the facilities (as approved by the
Division) shall be constructed and operational, and the stormwater management plan (as
approved by the Division) shall be implemented. The structural stormwater practices as
approved by the Division as well as drainage patterns must be maintained in perpetuity.
No changes to the structural stormwater practices shall be made without written
authorization from the Division of Water Quality.
If you do not accept any of the conditions of this Certification, you may ask for an
adjudicatory hearing. You must act within 60 days from the date of receipt of this letter. To
request a hearing, send a written petition that conforms to Chapter 150B of the North Carolina
General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh,
NC 27699-6714. This Certification and its conditions are final and binding unless you request a
hearing.
This letter completes the review of DWQ Project #01 1075 by the Division of Water
Quality under Section 401 of the Clean Water Act. If you have any questions, please contact
Mrs. Jennifer Frye at 336-771-4600, ext. 275 or Mrs. Cyndi Karoly at 919-733-9721.

Memorandum To: John Dorney
From: Todd St. John
Subject: Samaritan's Purse
Watauga County
DWQ# 011075
I have reviewed the stream relocation and stormwater manamgment plans for the subject
property. The stream plan is very similar to that of the Trillium project. The sites are very close to
each other. I did not have any major issues with the stream restoration plan. I did not ask for a
sediment transport analysis because of the small size of the stream and because the shear stress
appears to indicate that the channel is competent to transport the existing D95. Additionally grade
control structures are proposed. The existing Trillium project appeared to be functioning well at last
visit.
The stormwater management plan includes a 150' grassed Swale (only 70' is needed) and an
oversized dry detention basin. The needed drainage area to be treated is about 0.2 acres. The
applicant proposes treating 0.7 acres. Typically this would not meet condition 7 in the GC 3287;
however, the fact that the stream channel is being relocated and not piped and the stormwater is
more generous than required, I recommend that we approve the relocation and stormwater
management plan.

Materials Specifications
Grasses: Brown Top Millet or Rye Grain shall be used as temporary cover for
disturbed areas depending on time of year. A mixture of native grasses consisting
of Orchardgrass, Deer Tongue, Redtop, Caren strict_a and approved additions and
alternates (depending on availability) shall be used in Zone 2. Zone 1 and lA
shall be seeded with facultative wet and obligate wetland seed mix from Ernst
Conservation Seeds, or approved equivalent, at a rate of 10 IN per acre.
Live Stakes: Silky or Banker shrub Willow, Silky Dogwood, Red Osier
Dogwood, or approved alternates. Live stakes shall be between 18 and 36 inches
in length and a minimum of % inches in diameter. At least half of total length
must be installed in the ground. Leave at least 3 or 4 buds above ground. Plant
material may be harvested locally or obtained through an approved source.
Trees: Red Maple, Green Ash, Yellow Birch, River Birch, Sycamore, Ironwood,
Common Alder, Highbush Blueberry, or approved alternates. Plant material shall
consist of 18 to 36 inch bare root whips or container grown plants obtained from
local or regional sources or other approved sources.
Grade Control Structures: Rock to be used for construction of grade control
structures shall be 18"x I rx 24" with an acceptable range of 12" x 12" x 18" to
24" x 24" x 36". Grade control structures shall be installed according to details.
Location of structures is generally at top of riffle sections as noted on Control
Point Profile Elevation Table. Due to the extremely small size/width of this
channel rock cross vane construction will often be achieved with 3 large rocks. In
some cases only a single rock will be installed at streambed elevation to lock in
the thalweg elevation.
Sod Mats: Sod meats are to be harvested from the area of the proposed storm waxer
management grassed swale and detention basin. Mats shall be a minimum of 6"
thick and should be as large as possible (recommended S' x 3' x 6"). Double
handling of mats should be avoided. Mats shall be placed along channel according
to detail. Seams between adjacent mats shall as tight as possible with top surfaces
even and smooth. Live stakes shall be installed through mats to provide additional
anchoring.
Sills: Log sills shall be installed in the floodprone area adjacent to the proposed
channel to prevent cutoff chard formation. Logs shall have a minimum
diameter of 10" and shall not be less than 15' long. Sills shall be installed no
deeper than. 4" below finished ground surface.

Easement Narrative
A, pamanent vegeWed easement will be placed around the the portion of the
sed relocated . from station 110 to station;.380. Easement width will be
annum of 30 each side oa new stream channel from station 140 to
tatio x380. This easement shall b ecordi and copies/confirmation submitted to
the NC Division of Water Quality prior,. to occupation of tbe,proposed building
wilt'be planted in accordance with the attached
;iexptnsion. The easement
` B.evegetation Narrative and Plan. This plan provides for two planting zones within
thd` ent area, (Zone 1 a6d Zone 2). Zone 1 will extend a minimum of 15 feet
from the top of bank (bankfull) on each she with in ft easement. Zone 2 extends
from the limit of Zone 1 to the boundary of the east.
Management Strategy: Zone 1 will be managed as a natural. area with no fertilizer
or pesticide use. No mowimg or pruning will be allowed except to allow for access
to one or two benches and a viewing area. Zone two will be more actively
managed but native species composition will be maintained and no fertilizer or
pesticide use will be allowed. Grass in Zone 2 will be mowed periodically but a
minimum grass height of 3 inches will be maiintained.
Monitoring Strategy: The following monitoring plan for plant survival is
proposed: The total number and location, by zone, of trees and shrugs planted in
the riparian zone and eat area will be recorded on the As-Built plan to be
submitted to DWQ upon project completion. Trees and shrubs will be counted in
years 2,3 and 4 following construction and survival rate wilt calculated for each
species and reported
Streambank stability will. be monitored according to the following plan:
An As-Built plan will be prepared and submitted following completion of the
project. This plan will consist t of a complete "level 2" analysis of the stream
providing dimension, pattern, profile, and channel material information. Two
permanent cross sections will be established. This assessment will be repeated in
years 2,3 and 4 following completion of project. A report of findings will be
submitted to DWQ within 6 months of each assessment.

Stream Relocation Plan
Revegetation Narrative and Plan
The area surrounding the proposed stream relocation has been divided into three zones
(see plan). Zones 1 and 2 are to be within the proposed permanent easement boundary,
Zone IA will be outside the easement. Vegetation shall be established in accordance with
the following plan:
1. Following construction of the proposed new channel and installation of all
structures and sod mats seed all disturbed areas with temporary erosion control
mix appropriate for time of year.
2. Install live stakes in sod mats along channel and at top of bank. Spacing shall not
exceed five feet on center on either side of channel. Species to be used are listed
in the materials specifications section.
3. Riparian area (Zones I and 1A) shall be seeded with facultative wet and obligate
wetland seed max from Ernst Conservation Seeds, or approved equivalent, at a
rate of 10 Is per acre (see Stream Relocation Vegetation planting Plan),
4. Zones I and 1A shall be planted with trees and shrubs at a density of 500 plants
per acre. Live stakes planted along stream are included in this total. Approved
species are listed in the material specifications section.
5. Zone 2 shall be planted with native grasses from list in materials section or
approved alternates. This zone shall be planted with larger (generally 5' to 12'
W) landscape trees and shrubs. Tree and shrub species shall be from list in
materials specification section or approved alternates. This area will be planted at
lower density than zone I and plantings will be non-random so that this area will
serve as a transistional zone between the immediate riparian zone and the
surrounding, existing, landscaping of the site.
Grasses: Brown Top Millet or Rye Grain shall be used as temporary cover for
disturbed, areas depending on time of year. A mixture of native grasses consisting
of Orchardgrass, Deer Tongue, Redtop, Carex stricta and approved additions and
alternates (depending on availability) shall be used in Zone 2. Zone 1 and IA
shall be seeded with facultative wet and obligate wetland seed mix from Ernst
Conservation Seeds, or approved equivalent, at a rate of 10 lbs per acre.

Samaritan's Purse
Administration Building Expansion
Stream Relocation Plan:
Storm Water Management Narrative:
This project will result in a net increase in impervious area of $333 square feet. A storm
water management strategy is proposed to remove 85% TSS for an area equivalent to or
larger than the $333 sq. ft. This strategy consists of a grass swale leading to an extended
dry detention basin (see details and specifications). The extended dry basin will be
constructed in a mowed grassed area in the floodplain of East Fork on the Samaritan's
Purse property. The basin will be excavated into existing ground; all storage will be
provided below existing ground, no dams or berms will be constructed in the floodplain.
A standard riser stricture will be installed to provide the a detention time of 48 to 72
hours. Flows exceeding basin opacity will exit across a broad flat emergency spillway,
to be constructed as a level spreader, that ties into existing buffer vegetation adjacent to
East Fork. The floor of the basin will be seeded with a native grass seed mix containing a
variety of wetland species.
Grasses: Brown Top Millet or Rye Grain shall be used as temporary cover for disturbed
areas depending on time of year. The floor of the basin shall be seeded with facultative
wet and obligate wetland seed mix from Ernst Conservation Seeds, or approved
equivalent, at a rate of 10 1bs per acre.

Division of Water Quality
August 21, 2001
CERTIFIED MAIL: 7099 3400 0006 9313 6161
Return Receipt Requested
Samaritan's Purse
PO Box 3000
Boone, NC 28607
SUBJECT: APPROVAL of 401 Water Quality Certification with Additional Conditions
Samaritan's Purse Expansion
DWQ Project # 01 1075
Watauga County
Dear Applicant:
You have our approval, in accordance with the attached conditions (WQC #3287) and the
conditions listed below, to discharge fill into 240 linear feet of an unnamed tributary to East
Fork, Class WS-IV Waters, New River Basin, Watauga County for the purpose of expanding the
existing Administrative Building of the Samaritan's Purse facility. The activity must be
conducted as indicated in your application and Preliminary Grading, Drainage, and Erosion
Control Plan (Municipal Engineering Services Co., dated 6/26/01), received on July 12, 2001.
This approval is only for the impacts listed above and for the activities that you described
in your application and accompanying documentation received by the Division of Water Quality
on July 12, 2001. We have determined that General Water Quality Certification Number 3287
covers this fill activity. This Certification allows you to use Nationwide Permit Number 39
when issued by the US Army Corps of Engineers. Please keep in mind that there may be
additional Federal, State and Local regulations applicable to your project, such as the
Sedimentation and Pollution Control Act, Non-Discharge and Water Supply Watershed
Regulations, whereby you may be required to obtain permits and/or approvals prior to beginning
your project. In addition, this approval will expire when the accompanying 404 Permit expires
unless otherwise specified in the General Certification.
This approval is only valid for the purposes and designs that you described in your
application. If you change your project, you must notify the Division in writing and you may be
required to submit a new application for a new Certification. If the property is sold, the new
owner must be given a copy of the Certifications and approval letter and is thereby responsible
for complying with all conditions. If total wetland fill for this project (now or in the future)
exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H
01 1075
Page 2
.0506(h). For this approval to be valid, you must follow the conditions listed in the attached
Certifications and the additional conditions listed below:
Plans for the stream channel relocation and restoration shall be submitted to and
approved in writing by this Office before impacts to waters, streams or wetlands occur. It
is recommended that the check list provided in Appendix F in NCDENR's The Internal
Technical Guide for Stream Work in North Carolina, May 2000, be used as a guide to the
types of design parameters that must be addressed in order to obtain plan approval.
2. Once DWQ approval is granted (as outlined in Condition 1), the stream restoration shall
be built according to the approved plans before the proposed Administration Building
Expansion on site is occupied. If the stream relocation becomes unstable, the stream
shall be repaired or stabilized using only natural channel design techniques. Rip-rap or
other hard structures may only be used as temporary repairs if required by the NC
Division of Land Resources or Delegated Local Program. Additionally, all repair designs
must be submitted to and receive written approval from this Office before the repair work
is performed.
3. Since. 240 linear feet of the total stream restoration will be used as compensatory
mitigation for stream impacts, that portion (the restored channel plus the minimum 30
foot riparian buffers) shall be preserved in perpetuity through an easement or similar
legal mechanism. This easement or similar mechanism must be in place, and a copy
submitted to this Office, prior to occupation of the proposed Administration Building
Expansion.
4. The stream physical monitoring plan shall be implemented as described in your
application and reports must be submitted to this Office after the first year and every
other year afterwards for a total of five years.
5. The vegetation in the riparian area shall be maintained and/or replaced as necessary and
in accordance with the approved plan, to ensure a 5-year success rate of 320 trees per
acre.
6. As-built plans and the attached Certificate of Completion (COC) must be submitted to the
Division upon final construction of the relocated and restored channel.
7. An additional condition is that a final, written stormwater management plan shall be
approved in writing by the Division before impacts specified in this Certification can
occur. The stormwater management plan must include plans and specifications for
stormwater management facilities designed to remove 85% TSS according to the most
01 1075
Page 3
recent version of the NC DENR Stormwater Best Management Practices Manual. These
facilities must be designed to treat the runoff from the entire project, unless otherwise
explicitly approved by the Division of Water Quality. Also, before the Administration
Building Expansion is occupied at the subject location, the facilities (as approved by the
Division) shall be constructed and operational, and the stormwater management plan (as
approved by the Division) shall be implemented. The structural stormwater practices as
approved by the Division as well as drainage patterns must be maintained in perpetuity.
No changes to the structural stormwater practices shall be made without written
authorization from the Division of Water Quality.
If you do not accept any of the conditions of this Certification, you may ask for an
adjudicatory hearing. You must act within 60 days -from the date of receipt of this letter. To
request a hearing, send a written petition that conforms to Chapter 150B of the North Carolina
General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh,
NC 27699-6714. This Certification.and its conditions are final and binding unless you request a
hearing.
This letter completes the review of DWQ-Project #01 1075 by the Division of Water
Quality under Section 401 of the Clean Water Act. If you have any questions, please contact
Mrs. Jennifer Frye at 336-771-4600, ext. 275 or Mrs. Cyndi Karoly at 919-733-9721.

dams (separately list impacts due to both structure and flooding), relocation (include linear feet before and after, and net loss/gain),
stabilization activities (cement wail, rip-rap, crib wall, gabions, eta), excavation, ditching/straightening, etc. If stream relocation is
proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included.
*+* Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest
downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at
www.usgs.gov. Several internet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com,
www.mMuest.com, etc.).

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
With regard to avoidance and minimization it is informative to view the entire 17.5 acre
parcel which has developed under a master plan since the mid 1980's and is nearly fully
developed. Under the overall site plan buildings have generally been located either between the
road and the stream or between the stream and the floodway for East Fork. This pattern has left a
large vegetated area through which the stream flows now. It should be noted that the existing
stream is not of high quality from the standpoint of buffer q .t?ality, habitat, or stability. As a result
of this project 240 feet of existing channel will be replaced with 380 feet of more stable and
appropriat4e vegetated stream and associated buffer.

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/strm%zide.html.
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.
The proposed building expansion will result in the filling of 240 linear feet of a small
(DA=75 ac) perennial stream. The existing stream is an F-5 stream type with a mowed grass
buffer. Although direct evidence of past alteration has not been found, is appears likely that
at some time in the past this stream was other than an F-5 flowing in a straight oversized
trapezoidal "channel" The mitigation plan for this project involves the construction of 380
linear feet (a 1.58:1 ratio) of E-5 channel with a broad floodplain and buffer vegetated with a
mixture of native trees shrubs and herbs A 2grmanent conservation easement will be
established around the buffer area. The relocated channel will be located in the same geral
vicinity as the existing (see site pl@W bring back into the existing channel above and below
the proposed building _addition. The channel relocation will result in an improvement over the
existing condition by providing a more Upropriate stream t (E51 for this setting= this will
be achieved by reducing width/depth ratio providing a broad floodprone area, and increasing
sinuosity In addition to the change in stream type the relocated channel will be provided a
dedicated buffer zone (via conservation easement) vegetated with native species that will
Page 8 of 13
provide shading habitat and st&UV. While not required by proposed activity the stream
relocation will likely result in the creation of several thousand square feet of riparian
wetlands in the floodplam of the new channel Additionally a level spreader device will-be
installed to provide enhanced dissipation, infiltration and filtration of storm water discharged
into the floodplain This pipe c?,,irrentll discharges directly into the stream with no filtration
or dissipation
A full ggomo hic assessment of the existing. reach is provided in this package as well as
plans and specifications for the proposed relocated reach. Re-vegetation specations and a
monitoring plan are included as well. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at htm://h2o.enr.state.nc.uslwrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide

COMPENSATORY MITIGATION PROPOSAL
Samaritan's Purse Administration Building Expansion
Construction and Stabilization Narrative:
Construction of the proposed channel will be completed in the dry and will occur as the
first phase of site construction. Earth plugs will be left at upper and lower tie-in points to
existing channel. Flows from the existing channel will not be turned into the new channel
until the channel has been stabilized. Channel stabilization will be achieved through the
use of sod mat placement. Sod mats between 6" and 10" thick will be harvested from the
area of the proposed Storm Water Management BMP on-site. Sod mats will be anchored
with Willow and Dogwood live stakes. Grade control structures will be installed
throughout the project, primarily at the top of riffle sections. These structures will be
installed like cross vanes but due to the limited channel width will not strictly follow the
standard design. In some cases large rock will be installed at streambed to mimic a
bedrock control.
Revegetation Narrative:
Trees and shrubs will be planted in the riparian zone and proposed wetland area at a
density of 500 plants per acre. Species will include Red Maple, Green Ash, River Birch,
Hazel Alder, Silky or Bankers shrub Willow, and Silky Dogwood (and/or approved
additions or alternates). Plant material will consist of live stakes and 18" to 24" bare root
whips. The entire graded area will be seeded with a temporary cover for immediate
stabilization and overseeded with native grasses and wildflowers in the immediate
riparian area and obvious wet areas; remaining areas will be overseeded with a standard
lawn mix.
Velocity Issues:
Due to the extremely narrow nature of the active flow area of the existing channel
combined with the over-width status of this channel and long term maintenance activities
on this site, all but one foot or so of the bankfull width of the channel is grass. This
resulted in an extremely fine D50 and D84 (0.12 and 1.3mm respectively). One result of
this pebble count is that the method of calculating velocity using the D84 provided results
that made no sense. The velocities shown on the morphological Measurement Table for
the project stream were derived from regional curve relationships reported in "Bankfull
Regional Curves for North Carolina Mountain Streams", Harmon, et. al.
It is anticipated that after completion of the relocation, the corrected channel geometry
will result in a better defined channel bed and bank and the pebble count information will
change significantly. Two other channels of virtually the same size and in the same
vicinity (within 0.5 miles, in the same valley and draining to East Fork) have been
evaluated for channel materials; these are a G5/F5 with a D50 of 0.85mm and a D84 of
19mm, the other is a Eb5 with a D50 of 4.3mm and a D84 of 60mm.
A second velocity related issue involves the existing culvert located on the adjacent
property immediately upstream of the beginning of this project. This is a 30" CMP (see
Grading, Drainage and Erosion Control Plan) that has limited available headwater before
flows of greater magnitude would exit the channel overland in a northeasterly direction
toward East Fork thereby by-passing the proposed channel altogether. The maximum
available headwater for this culvert is approximately 1.75 (HWJD). This condition limits
flow to approximately 30 cfs (about 1.5 times bankfull). The Q10 for the project reach is
estimated to be roughly 90 cfs which would far exceed the culvert capacity.
Sediment Transport Issues:
Due to the extremely small size of this stream a standard analysis of sediment transport
(entrainment calculations, etc.) was not practically feasible. There were no bars from
which to sample and the area of unsilted or unvegetated channel bottom is so small that
an in-channel pavement/sub-pavement sample would be difficult and yield little more
than silt and sand. Generally in sand bed streams it is assumed that there will be sufficient
energy to move the sand. In this case the largest particle sampled was 35mm (very coarse
gravel) and this was an outlier, the D50 is 0.12 mm and the D95 is 9.1mm. As pointed out
in the velocity discussion it is anticipated that channel particle size will increase as a
result of the proposed relocation The project is proposed in an area dominated by
Chewacla loam, an alluvial loam with limited gravel and cobble within 42 inches. The
history of this subbasin is agricultural with a large amount of recent development and
channel alteration which may allow for the availability of larger particles. Unfortunately
there is limited data to determine if such larger particles could be moved. It appears that
the substantial reduction in slope will contribute to a reduction of both shear stress and
stream power in the proposed channel but according the Shields curve there will be
sufficient energy to move sediment based on available data.
Storm Water Management Narrative:
This project will result in a net increase in impervious area of 8333 square feet. A storm
water management strategy is proposed to remove 85% TSS for an area equivalent to or
larger than the 8333 sq. ft. This strategy consists of a grass swale leading to an extended
dry detention basin (see details and specifications). The extended dry basin will be
constructed in a mowed grassed area in the floodplain of East Fork on the Samaritan's
Purse property. The basin will be excavated into existing ground; all storage will be
provided below existing ground, no dams or berms will be constructed in the floodplain.
A standard riser structure will be installed to provide the a detention time of 48 to 72
hours. Flows exceeding basin capacity will exit across a broad flat emergency spillway,
to be constructed as a level spreader, that ties into existing buffer vegetation adjacent to
East Fork. The floor of the basin will be seeded with a native grass seed mix containing a
variety of wetland species.
MONITORING PLAN for PROPOSED RELOCATED UT to EAST FORK
Samaritan's Purse Administration Building Expansion
1. The following monitoring plan for plant survival is proposed:
a. The total number and location, by zone, of trees and shrubs planted in the
riparian zone will be recorded on the As-Built plan to be submitted to
DWQ upon project completion.
b. Trees and shrubs will be counted in years 2,3 and 4 following construction
and survival rate will calculated for each species and reported.
2. Streambank stability will be monitored according to the following plan:
a. An As-Built plan will be prepared and submitted following completion of
the project. This plan will consist of a complete "level 2" analysis of the
stream providing dimension, pattern, profile, and channel material
information. Two permanent cross sections will be established.
b. This assessment will be repeated in years 2,3 and 4 following completion
of project. A report of findings will be submitted to DWQ within 6 months
of each assessment.
3. Given that the length of stream to be impacted is only 240 linear feet no
monitoring of macrobenthos is proposed.

SUBJECT: Review of an Application by E'nV Environn
Samaritan's Purse Administrative Office Bui
Tributary to East Fork, New River, Watauga
The applicant is requesting a letter of concurrence frc
Commission (NCWRC) to obtain a 404 permit from the U.S.,
linear feet of the referenced tributary (F-5 stream type) using t
reviewed information provided by the applicant, and field biol
values of the project area. These comments are provided in ac
Act of 1977 (33 U.S.C. 466 et. seq.) and the Fish and Wildlife
16 U.S.C. 661-667d).

Consulting Services, Inc. for
and Stream Relocation, Unnamed

ny Corps of Engineers to relocate 240
-ngineering techniques. The NCWRC has
ists on our staff are familiar with habitat
rdance with provisions of the Clean Water
)ordination Act (48 Stat. 401, as amended;
The new relocated channel (E-5 stream type) will be 380' long with natural vegetation within a
dedicated conservation easement. Additionally, a small riparian wetland is anticipated for the floodplain,
We recommend minimum 25' naturalized forested buffers along the new channel. Based on the
information provided by the applicant and our information on the range of trout in the project area, we do
not believe this project will cause significant effects to waters supporting trout providing the following
conditions are implemented:
1. Instream work and land disturbance within the 25-foot wide buffer zone are prohibited
during the trout spawning season of October I'I1.5 through April 15 to protect the egg and
fry stages of trout from off-site sedimentation during construction.
2. Stringent erosion control measures should be installed where soil is disturbed and
maintained until project completion.
3. Native species should be used for streambanl stabilization and restoration.
Thank you for the opportunity to review and commen? on this project. If you have any questions
regarding these comments, please contact me at 336/769-9453,
