Ms. Jones
This PCN addendum/modification to the PCN submitted for the referenced project is in
response verbal comments received during a phone conversation between you and John
Vilas as well as a site visit by Sue Homewood and Eric Kulz of the NCDWQ on
September 17, 2007 which was followed by a letter of recommendation for the project.
Based on these recommendations, the project design has been slightly altered for the
stream relocation and pond construction portions of the original submittal. The
construction of Pond 2 was eliminated; Pond 3 has been renamed to Pond 2 and slightly
increased in size. The relocation of the intermittent stream, UT-NFSC has been
eliminated. Since a 78 if section of this intermittent stream would have been impacted by
the originally proposed intermittent stream relocation, Stream Impact 1 site has been
eliminated with this re-submitted PCN application. The restoration of the North Fork of
Sawyer Creek has been slightly shifted on the lower portion of the stream eliminating a
lower debris blockage; no changes in net length, channel dimensions, slope
characteristics, or tie-in locations have been made from the original PCN submittal. Net
wetland impacts have been reduced by 90 sf with changes from the realignment of the
restored portion of the North Fork of Sawyer Creek as well.
Thank you, /

10. Describe the overall project in detail and the purpose of the proposed work: The purpose of
the project is to restore the North Fork of Sawyer Creek to its previous existing channel prior
to the hurricane induced floods in September 2004. To construct a subdivision access road
across the valle~gh which North Fork Sawyer Creek flows; this road will involve a
bride crossing over North Fork Sawyer Creek. To construct 2 small off-line ponds in the
current (to-be-abandoned) path of NF Sawyer Creek. To construct a network of subdivision
roads and driveways to access approximately 7 lots within the 32.2-acre tract; the
construction of this road network will involve the installation of 2 wiped driveway crossings
on the intermittent tributary, UT North Fork Sawyer Creek.
There are three categories of activities that will result in impacts to jurisdictional waters of
the United States on the project site:
1. Stream Restoration: This phase of the project will involve the restoration of
approximately 700 linear feet of North Fork Sawyer Creek. This stream is a second
order stream with a drainage area of approximately 1.03 square miles. This stream is
classified as an D4b through the project reach. Above the proposed restoration reach
the stream is a B4 and appears much more stable; this reach is used as the reference
reach for the restoration design. During the fall of 2004 two major, hurricane
induced, flooding events occurred that caused a large debris dam in the channel at the
location indicated on the Existing Conditions Map, following the storm a new flow
pattern had formed to the left of the original channel. The new channel exists today
but is significantly undersized, is head-cutting rapidly in two locations, has poor
habitat quality,, and is eg_ nerally unstable. This channel, if left alone, will undergo
dramatic adjustments in dimension, pattern and profile, resulting in severe in-channel
erosion and poor habitat qualityyears before again becoming stable. The
proposed restoration project will involve the removal of a debris blockage at the
upper end of the restoration reach. The existing_(original) channel below the debris
blocka e is in food shape and requires only minor radin~ to the upper banks in
places to restore abank-height ratio of 1.0. A second debris blockage, approximately
200 feet in length, is located at the lower end of the reach (proximately 500 feet
below the upper blockage); both areas ag~raded during the 2004 floods. This lower
debris blockage will be removed as well matching the on ig nal pattern; a reach
approximately 200 feet in length will be constructed through this area and will be
designed based on the reference reach located immediately above the upper debris
blockage. In addition, minor adjustments will be made to the remainder of the reach
to establish the proper dimension, pattern and profile. At the completion of the
restoration approximately 550 linear feet of the currently flowing (post 2004
hurricane) channel will be abandoned and filled. The goal of the restoration project
will be to reestablish a stable "B4" channel through this valley
2. Pond Construction: Two small ponds are proposed along the path of the currently
flowing channel and are shown on the Proposed Site Plan.. The Qrimar~purpose of
these ponds is aesthetic. The ponds will be constructed by excavating down below
existing_grade and berming around the perimeter. The perimeter berms will serve to
limit the available flood prone area adjacent to the restored reach of N.F. Sawyer
Shikina Falls and Meadows Page 3 of 11 PCN Addendum
September 27, 2007 ENV-ECS, Inc.

Creek in order to bring the entrenchment ratio more in line with a "B" channel. The
berm around the ponds will effectively prevent the stream from following the same
path as during the 2004 floods. The berm surrounding Pond 2 will impact a small
area of wetlands, shown as Wetland Impact 1 on the Site Impact Map. This wetland
unit, NFSC-W 1 is associated with a linear spring head next to the state road (Camp
Job) and feeds an area of wetlands adjacent to North Fork of Sawyer Creek
which most likely formed during the floods by debris damming.
Driveway Crossings: Two piped crossings are proposed over the intermittent
unnamed tributary to the North Fork of Sawyer Creek. Both crossings are for private
driveways that will access 2 or fewer lots. Both proposed pipes will be 40 feet loner
This len tg~h of pipe is needed to allow for 8 to 10 feet of fill over the pipes to reduce
required cut and fill impacts associated with driveway construction. A low retaining
wall will be used to confine the fill at the upper crossing location, Stream Impact 3.
These two culvert installation impacts are referenced on the Site Impact Map as
Stream Impact 2 and 3.

4. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ®uplands ^ stream ®wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): Ponds will be created by excavation into water table
and small ape diversion from NFSC upstream. A low berm will be constructed around ponds
berms will not exceed 8 feet in hei hg t. All ponds will be much less than 10 acre-feet and no
containment structure will exceed 15' in height.
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): Two small aesthetic ponds are proposed near the
entrance to the nroiect and will be constructed in the path of the. currently flowing channel,
post-2004 flow pattern. The upper pond, Pond 1 will be fed by a diversion from N.F. Sawyer
Creek and Pond 2 will discharge back into N.F. Sawyer Creek from a cold water release.
Size of watershed draining to pond: Pond l :less than 0.25 acres, Pond 2: less than 0.25 acres.
Expected pond surface area: Pond 1: 0.2-acres, Pond 2: 0.3-acres

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.
There are three activities that will result in impacts to jurisdictional waters of the United States:
Stream Restoration: This phase of the project will involve the restoration of
approximately 700 linear feet of North Fork Sawyer Creek. Impacts associated with this
restoration effort are fully_justified because the restored channel will be more stable,
provide better habitat and will be approximately 100 feet longer than the existing
flowing channel on the site. Furthermore, impacts will be minimized by all restoration
work being_performed in the dry. This restoration effort is justified to minimize the long
term erosion and sedimentation effects that will result if the current flow path is allowed
to continue to adjust and stabilize naturally. The current channel (post-2004 flood flow
path) is best classified as a "D4b" (Rosgen terminology) but this is not a perfect fit as
illustrated by its cross-sectional area of 7.5 sq.ft. compared to the bankfull azea above the
upper debris blocks eg along the N. F. Sawyer Creek which is 18.85 sq.ft. The difference
in channel azea explains the widespread evidence of flow and associated erosion and
deposition along this section of the valley. During large flow events, evidence indicates
water spills back into the original pre-2004 channel in the vicinity of the proposed
restoration area, but because of the debris blockages within the valley these out-of--bank
flow events only fill up the old channel periodically before resuming flow down the
valley. We conclude that the proposed stream restoration project will provide the
following beneficial effects on the impaired section of the North Fork of Sawyer Creek:
a. Remove the debris blockages,
b. Restore the stream to the original channel,
c. Provide enhancements to the original channel and surrounding flood-prone-azea
to prevent future side channel formation, and
d. Provide ripazian plantin sg_ alongithe entire corridor
A stream restoration project at this site will eliminate a long_period of channel adjustment
and instability associated with erosion and stream sedimentation. The proposed
restoration will also~y enhance in-stream habitat for trout and other aquatic life.
Pond Construction: Impacts associated with the construction of the two small ponds has
been minimized by making the ponds smaller than on finally desired and keeping the
ponds off-line. Both ponds are proposed along the path of the currently flowing channel
that is to be abandoned following the restoration portion of the project. The primary
purpose of these ponds is aesthetics. The ponds will be constructed by excavatin d~
below existing_grade and berming around the perimeter. The perimeter berms will serve
to limit the available flood prone area adjacent to the restored reach of N.F. Sawyer
Shikina Falls and Meadows Page 7 of I I PCN Addendum
September 27, 2007 ENV-ECS, Inc.

Creek in order to brim the entrenchment ratio more in line with a "B" channel The berm
surrounding Pond 2 will impact a small area of wetlands shown as Wetland Impact 1 on
the Site Impact Map. This wetland unit, NFSC-W 1 is associated with a linear spring
head next to the state road (Camp Joy Rd•) and feeds an area of wetlands adjacent to
North Fork of Sawyer Creek which most likely formed during the floods by debris
damming.
3. Driveway Crossings: The main subdivision entrance road was designed to avoid any
impacts to jurisdictional waters of the United States crossing such waters by constructing
a bridge spanning the restored stream channel with no resulting impacts There will be
two piped crossings of the intermittent stream UT-NFSC these are both associated with
private driveways. Impacts have been minimized with these crossings b~ping the
driveway widths to 12' and by using a retaining wall to limit the extent of fill in the
vicinity of the stream. These culverts will be countersunk during installation in order to
provide substrate for the redevelopment of aquatic habitat.
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/strn~~,ide.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,
Shikina Falls and Meadows Page 8 of 11 PCN Addendum
September 27, 2007 ENV-ECS, lnc.

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.
Mitigation on the Shikina Falls and Meadows site will consist of the stream
restoration project along the North Fork of Sawyer Creek, which will replace an
unstable eroding channel created during the 2004 flood with a stable properly sized
channel and a net increase of approximately 100 linear feet of B4 channel. A
minimum vegetated buffer width of 25 feet will be established around the restored
channel.
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 http:~/h2o.enr.state.nc.us.%wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide

(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ^ No ® If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.

Gone 1 extends out 3U teet perpendicular from near bank of channel; Lone 2 extends an
additiona120 feet from the edge of Zone 1.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration /Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or .0260.
XI. Stormwater (DWQ Only)
Describe impervious acreage (both existing and proposed) versus total acreage on the site.
Discuss Stormwater controls proposed in order to protect surface waters and wetlands
downstream from the property.
Pre-development impervious cover on the site is essentially zero. The subdivision development
will consist of 7 single family lots with approximately 5000 sq. ft. per lot of impervious cover
and approximately 1900 linear feet of subdivision glade road with an average width of 20 feet.
Adding an extra 7000 sq. ft. for currently unplanned improvements, the total impervious cover
on the site is approximately 1.84-acres; the total site area is approx. 32.2-acres bringing the total
impervious cover for the site to approx. 5.7%. There are no high intensity areas of development
proposed.

XII. Sewage Disposal (DWQ Only)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Each lot will have an individual septic system with no anticipated discharge of wastewater. Each
septic drainfield will be installed according to Watauga County standards and inspected by
Health Department officials.
XIII. Violations (DWQ Only)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ^ No
Is this anafter-the-fact permit application?
Yes ^ No
XIV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
