RE: DWR Request for Additional Information
Cashiers Canoe Club
Jackson County, North Carolina
Action ID SAW -2016-00032; DWQ Project # 2018-0582
Dear Ms. Homewood,
Please reference the letter dated June 6, 2018 (Attachment A) sent by the NC Division of
Water Resources (DWR) in response to the permit application submitted by Clearwater
Environmental Consultants, Inc. (CEC) on behalf of the Cashiers Canoe Club
Development (Applicant) represented by Ms. Roseanne Giordani. The permit application
requested written authorization for impacts associated with the maintenance dredging of
the existing Cashiers Lake and associated mixed-use development. Comments provided
by the DWR are discussed below.
In response to these concerns, the Applicant has engaged in additional review of the
proposed project. LandDesign is now the civil engineer for the project development and
has provided new input on previously designed and submitted site plans. Based on this
collective review, the Applicant proposes the following adjustments:
• The Applicant proposes the installation of a pond forebay. The forebay
would provide upland access for future lake maintenance/dredging
activities and would assist in reducing future siltation of Cashiers Lake.
• To accommodate pre and post -construction equipment access and staging
from Frank Allen Road to the proposed forebay, the Applicant proposes a
0.12 acre increase on Impact 413 from 0.24 acre to 0.36 acre.
• Proposed dredging Impact #12 has been reduced by 0.18 acre.
• The proposed dredging/impact from the lake bed has been reduced from
17.37 acres to 3.34 acres, which is a reduction from 77,000 cubic yards to
36,500 cubic yards.
• The Applicant proposes to utilize a temporary diversion ditch to redirect
incoming stream flow within the proposed wetland dredge area. Cashiers
Lake would be drawn down via a mechanical pump to four feet below the
normal pool elevation (from approximately 3,471 feet to 3,467 feet)
during construction activities. A siphon would also be utilized to draw

down water within the lake after rain events. The use of turbidity curtains
within Cashiers Lake is also proposed.
In all events, the Applicant is confident that its continuing commitment to mitigation
measures, which are designed to minimize all impacts associated with the proposed
development, provide reasonable and adequate assurances for the construction and
operation of the proposed activities for which authorization is sought, and construction
and operation of additional development will not result in significant, adverse impacts to
the natural environment. Additional information regarding various impact issues is
presented below.
DWR Comment # 1 - Provide a detailed purpose and need for lake dredging. This
should include an analysis of what activities are unable to occur if the wetlands are not
impacted, and whether the activities could be practically accomplished if the wetland
impacts are reduced.
The primary purpose and need for the lake dredging is for lake maintenance
resulting from years of deposits of sediment from upstream. As shown in the
historical aerial photographs, the size of the lake has reduced significantly from
these impacts, and it will most likely continue unless efforts are made to remove
the sedimentation on a more regular basis.
If dredging is not conducted, the lake will continue to fill in with sediment and
eventually, there would be no lake. Following dredging, the lake will continue to
accumulate sediment. The Applicant needs to conduct maintenance dredging in
order to have a lake and would be pursuing dredging with or without adjacent
development.
DWR Comment #2 Provide a schedule for the construction of the proposed
development (subdivision, hotel, parking area, and associated amenities).
The proposed construction development schedule is as follows:
• Wetland Dredging: May -June 2019
• Bulkhead Construction: June 2019 — August 2019
• Dock Construction: September 2019
• Sales and Rental Commercial Site: March 2020
• Residential Development 1: March 2020 — June 2020
• Hotel Site: March 2022 — June 2023
• Residential Development 2: March 2023 — June 2024
DWR Comment # 3 - Provide a purpose and need for the bulkheads, including impacts
#1, #3, #5, #9, and #I1. Also provide a detailed avoidance and minimization analysis for
the bulkheads.

Ms. Sue Homewood
10/30%1018
Page 3 of 7
Proposed bulkheads located at Impact #2 and Impact #5 would be utilized for on-
site storage of dredged material. Allocating approximately 1.39 acres of dredged
waste material (approximately 14,000 cubic yards) for the use of bulkheads
provides a means of disposal within the immediate vicinity of dredging activities.
As a result, off-site disturbance would be reduced by using bulkhead construction,
and the acreage of material requiring removal to the proposed dredge material
waste area would be reduced, which will also reduce costs. These areas would
also provide additional access points to the lake for passive recreation (canoeing,
fishing, swimming, etc.).
The proposed bulkheads also serve a function from an operation standpoint as
well. Installation of the bulkhead associated with Impact #11 and Impact #13
(Figure 3.0, Attachment B) would protect banks from shoreline erosion and assist
in maintaining an open channel from where the headwaters of the Chattooga
River flow into the lake and contribute significant amounts of sediment. The use
of bulkheads will allow room to grade between the steeper terrain to the west and
the lake. This graded area will be used for future dredging access from high
ground as well as part of the walking trail network and fishing access.
DWR Comment # 4 -The jurisdictional determination submitted with the application
indicates that there are/were out parcels that were not delineated, specifically an out
parcel between wetland 3 and wetland 5 that may have additional jurisdictional features.
Please locate all wetlands, streams, and other waters of the state as overlays on a
detailed site plan. This should include all areas idents; fled as jurisdictional by the USA CE
within the project boundary. Also, clearly locate the Chattooga River where it is
immediately adjacent to the project boundary. [15A NCAC 02H.0502)
Figure 3.0 is revised (Attachment B) and clearly shows all jurisdictional areas
(wetlands, streams, open waters) as requested.
DWR Comment # 5 - Please note that in accordance with 15A NCAC 02H.0500, the
Division requires mitigation for all impacts greater than 1 acre of'wetlands. Your
proposed total wetland impacts for this project are 6.96 acres. You propose in your
application to mitigate for impacts by payment to the Division of Mitigation Services
(DMS). Provide an acceptance letter from DMS indicating acceptance of 6.96 acres of
wetland mitigation.
CEC submitted a revised request to NC DMS for 8.99 acres of wetland and will
forward the acceptance letter to DWR and the US Army Corps of Engineers when
this information is available.
DWR Comment # b - Provide more details regarding avoidance and minimization for
impact 413. The application does not discuss what the purpose of the parking area and
building is for. Revise the plans to minimize the impacts or provide a detailed
explanation of why this plan for the activity cannot be practically accomplished, reduced
or reconfigured to better minimize disturbance to the wetland.

Ms. sue Homewood
10/30/2018
Page 4 of 7
The purpose of the proposed development identified at Impact 413 is for the sales,
rental center, and development office. This approximately 2,750 square foot
building will be used by the Applicant for sales and office during development
activities. Once a sales center is established on-site, the building will be primarily
used for retail and as an office. For these uses, this facility requires at least 29
parking spaces per local parking ordinances and consumer demand. Based on our
proposed layout, please note that the parking and building are pushed as far
Northeast as possible to avoid wetland impacts. Site development is also
constrained since there is currently no driveway access point to this site. The
proposed driveway shown on our exhibits is located directly across from the Bum
Street Intersection as required by NCDOT. The site was cleared and maintained
as an herbaceous wetland by the previous owner. A picture of the proposed
impact area is included in Attachment C.
DVM Comment #7 - Provide more details regarding avoidance and minimization at
impact #6, #7, and #8. Show all existing access roads/driveways/culverts for the existing
development and homes within this area on the plans. Provide a detailed explanation of
why the development layout/design cannot be practically accomplished, reduced or
reconfigured to better minimize disturbance to the streams and/or wetlands.
Road crossings are necessary to access upland areas. Please note that there is an
existing home located between proposed Impact #6, Impact #7, and Impact #8
(Figure 3.0, Attachment B). An existing pedestrian bridge is used to access this
home site, and two road crossings are necessary to access the upland areas on
either side of this house that are proposed for development.
DWR Comment # 8 - Provide a site plan with the proposed development and lot layout
as an overlay including jurisdictional features. Provide building envelopes for all lots
with wetlands, streams or trout buffers and stormwater setbacks on the site plans to
demonstrate these lots are able to be developed without additional jurisdictional impacts.
Please be advised that deed notifications or other legal language that clearly indicates to
future owners that there are jurisdictional features and that some lots may not be
buildable as planned without impacts that may not be approved .by the regulatory
agencies will be a condition of the 401 Water Quality Certification.
A revised site plan (Figure 3.0, Attachment B) is attached and includes building
envelopes for lots with wetlands, streams, ORW buffers, and stormwater setbacks
in additional to all jurisdictional features. As shown, all lots are buildable without
additional impacts to wetlands, streams, trout buffers, and stormwater setbacks.
DVM Comment #9 - Clarify whether the Division of Energy, Mineral and Land
Resources will require riprap within any stream channels or wetlands as part of the
Erosion & Sedimentation Control Plan approval (including temporary impacts from lake
dewatering discharge). If riprap is required, enumerate and clearly label the temporary
and permanent impacts on the site plan and submit a channel restoration detail. Riprap
must be located below the stream bed elevation.

Ms. Sue Homewood
10/30/2018
Page 5 of 7
The dewatering device will utilize the existing cold -water release pipe, culvert,
and dissipater pad (Sheet 0-00 and Sheet 0-01, Attachment D). There are no
new proposed impacts associated with the dewatering device.
Temporary placement of riprap in the proposed wetland dredge area is shown on
Sheet C3-00 (Attachment D). This riprap is associated with a temporary sediment
basin (0.01 acre) and construction access (0.13 acre) and haul roads (0.10 acre) as
needed (approximately 0.24 acre of riprap) and will be removed upon completion
of the project. Additional riprap and gravel are proposed to create a permanent
forebay (0.21 AC) as shown on the revised Sheet 0-00. The proposed forebay
will be included on plans submitted to DEMLR and will provide upland access
for future maintenance activities.
DWR Comment #10 - Enumerate all wetland and stream impacts including but not
limited to fill slopes/dissipater pads/temporary dewatering impacts on the site plan and
clearly label impacts. The Division recommends highlighting by hatching or shading all
permanent and temporary impacts.
Figure 3.0 (Attachment B) is revised, and proposed Impact #13 is now shaded.
Potential temporary impacts associated with construction access within the lake
bed have also been added to Figure 3.0. The figure now clearly indicates all
proposed impacts to jurisdictional features.
DWR Comment #11 - Provide a detailed engineering plan, profile view, and cross-
section of all proposed culverts. These drawings must include details regarding stream
alignment in relation to pipe alignment, pipe slope, pipe burial, and dissipater pad.
Provide cross section details that clearly show the provisions for aquatic life passage.
Detailed engineering drawings prepared by LandDesign are included in
Attachment D (Sheet 0-04). These drawings include profile and cross-section
views of all proposed culverts, and provide details regarding pipe alignment,
slope, burial, installation, and provisions for aquatic life passage. Please note that
impacts have changed for each of the proposed culverts. Impacts now total 60
linear feet per culvert: 30 linear feet of culvert and 30 linear feet of riprap (15 feet
for inlet protection and 15 feet for outlet protection).
DWR Comment # 12 - Provide details on how you are going to maintain the physical
integrity of the stream above and below the culvert where multiple culverts are proposed
Where multiple pipes or barrels are required, they shall be designed to mimic natural
stream cross section as closely as possible including pipes or barrels at flood plain
elevation and/or sills where appropriate. Widening the stream channel should be
avoided. Stream channel widening at the inlet or outlet end of structures typically
decreases water velocity causing sediment deposition that requires increased
maintenance and disrupts aquatic life passage. A construction sequence and detail
should be provided to ensure the contractor is clear on construction of these benches.

Ms. sue Homewood

The road crossings have been reevaluated by LandDesign. LandDesign has
provided site specific culvert plans and details (Sheet C3-04, Attachment D) that
indicate the use of a single culvert at each proposed stream location. The details
also provide for aquatic life passage. Please reference the response to DWR
Comment #11 above.
DWR Comment #13 - The stream impact length should be measured along the
centerline of the stream. When proposing a culvert, the impact length is generally greater
than the length of the culvert and associated dissipater since the existing stream usually
has some sinuosity (curvature). Verify that stream lengths have been surveyed or are
otherwise accurate or provide updated impact lengths.
The proposed stream impacts for the road culverts have been measured along the
centerline of the stream. The proposed impact numbers are identified on the
revised Figure 3.0 (Attachment B).
DWR Comment # 14 - All development within this project is subject to 15A NCAC 02H
.1021. Provide documentation of an approved stormwater permit issued by the Division
of Energy, Mineral and Land Resources for all proposed built upon areas.
A stormwater management plan for the residential areas identified on Figure 3.0
(Attachment B) and as "DA 46" on Sheet C2-00 (Attachment D) was submitted
by LandDesign on April 9, 2009 and was approved on May 14, 2009 under
Stormwater Permit No. SW1080801. Conceptual stormwater plans for areas "DA
#1" through "DA 45" are also provided on Sheet C2-00 and include the use of
underground stormwater treatment and one wet pond.
DWR Comment # 15 - The application states that increased turbidity "may occur" as a
result of the proposed project. Due to the sensitivity of downstream waters, provide a
detailed contingency plan for large and/or prolonged precipitation events. Please note
that duplicity and/or oversight should be addressed if the plan relies on mechanical
equipment for downstream water quality protection and/or routine erosion control
measures. Due to the sensitivity of downstream waters the Division requests that an
approved Erosion Control Plan be secured prior to issuance of a 401 Certification.
A preliminary Erosion Control Plan is provided in Attachment D. A site visit and
initial field review of proposed plans was conducted by LandDesign, CEC, and
Mr. Stan Aiken (DEMLR) on October 9, 2018. A finalized Erosion Control Plan
will be submitted for approval by DEMLR. The approved plan and associated
documentation will be provided to DWR.
Proposed construction activities will not occur during large and/or prolonged
precipitation events. Additionally, LandDesign has provided a draft Cashiers
Lake Dredging Plan (Attachment D), which includes a proposed turbidity
monitoring plan.

Ms. Sue Homewood
10/30/2018
Page 7 of 7
DWR Comment #16 - Provide a lake dredging plan that clearly indicates how
downstream water levels will he continuously sustained during dredging and during
refilling of the lake. Please note that duplicity and/or oversight should be addressed if the
plan relies on mechanical equipment for continuous minimum flow.
A draft Cashiers Lake Dredging Plan is included in Attachment D. The
construction sequence is also included on Sheet C3-02 (Attachment D). A
temporary diversion ditch will be constructed and utilized to direct the incoming
water within proposed wetland dredge area (Sheet C3-00, Attachment D). An
initial drawdown and post -construction refill of the lake will occur via a
mechanical pump connected to an existing outlet and gravel dissipater pad.
Turbidity curtains will be installed within the lake, which will act as a stilling
basin during construction activities. Water level within the lake will be controlled
via siphon during dredging and the contractor will coordinate work with rain
events.
The Applicant believes the information submitted in this package addresses all issues set
forth by the DWR in the letter dated June 6, 2018. Should you have any questions or
comments concerning this project please do not hesitate to contact me at 828-698-9800.

Cashiers Lake
Dredging Plan
NARRATIVE
PROJECT 8118068

NARRATIVE
Introduction
Cashiers Lake is a 30 acre ± man made water body located on Cashiers Road (SR 1113) within Cashiers
Township, Jackson County, NC. The Cashiers Canoe Club Development LLC is seeking authorizations
associated with dredging Cashiers Lake in order to restore functionality due to excessive sediment
loading that has taken place over the last 50 years. The total area disturbed for the proposed plan is
approximately 20 ± acres. All construction on the site shall be in accordance with North Carolina
Department of Environmental & National Resources (NCDENR) Erosion Control Planning & Design
Manual Standards and Specifications and adhere to the Division of Water Quality Rules & Regulations.
Conceptual Stormwater Management Master plan
The minimum stormwater regulations are detailed in Section 15A NCAC 02H .1007 Stormwater
Requirements: Outstanding Resource Waters of the North Carolina Administrative Code as they apply to
developments which drain to freshwaters. Canoe Club must meet the following requirement:
1. Control systems must be wet detention ponds or alternative stormwater management systems
designed in accordance with Rule .1008 of this Section; and
2. Control systems must be designed to control runoff from all surfaces generated by one inch of
rainfall
The overall project approach for Cashiers Lake Resort is to preserve as much as possible of what makes
the site special, including richly diverse vegetation (old growth trees and rich understory), terrain
(drainage patterns) and pristine waters (cool mountain streams and the beautifully serene Cashier's
Lake). The pian is designed to take advantage of existing landforms and access roads and limit clearing
to the minimum necessary for roadways, driveways and home construction while specifying construction
sequencing that is mindful of the end result. The increased runoff generated by new development will be
handled through a combination of Low Impact Development techniques, along with structural BMPs
designed to treat the 1" rainfall, including preserving trees, minimizing connected surfaces and promoting
infiltration through infiltration swales and rain gardens designed to take advantage of the highly pervious
native soils. The stormwater management plan utilizes existing natural drainage paths and minimizes the
concentration of stormwater discharges as much as practical. Currently, Canoe Club LLC has on file an
approved stormwater permit SW 1080801 issued May 14, 2009 for the subdivision portion of the
conceptual stormwater management master plan area (see attached).
Erosion Control
Erosion control on the site shall comply with (NCDENR) Erosion Control Planning & Design Manual
Standards & Specifications.
The erosion control design focuses on capturing sediment near the source, along with protecting
downstream flows to sensitive trout waters. One main focus of the proposed plan is to develop a more
effective lake and protect the primary water body from upper basin sediment transfer from under Frank
Allen Road.
The Construction Sequence for the Erosion Control is as follows:

1. Contractor shall verify that all applicable permits have been obtained prior to the beginning of
construction, and hold a preconstruction meeting and coordinate with owner, engineer, and all
applicable regulatory agencies.
2. Project is located in an environmentally sensitive area and is adjacent to a trout stream. Contractor
shall use extreme care throughout project.
3. Submit shop drawings to engineer for review and approval for all materials.
4. Contractor shall notify all affected property owners and obtain permission for property access prior to
proceeding with work.
5. Contractor should locate all existing utilities within the defined project area as shown in the erosion
control plan. Contractor shall notify engineer if there are any discrepancies between the plans and
field conditions.
6. Contractor shall work within allowable construction limits — sensitive property owners.
7. Contractor shall maintain vehicular access along Cashiers Lake Road (SR 1113) at all times.
8. Stabilize construction entrances and access drives with gravel and mulch. Stake clearing limits.
9. Install all upland silt fence, and other measures as shown on plans, clearing only as necessary to
install these devises.
10. All erosion measures shall be constructed in accordance with the NC erosion and sediment control
planning and design manual and US Department of Agriculture.
11. Call for on-site inspection by inspector and engineer.
12. Contractor shall lower the lake from the NWSE of 3471 to 3467. The dewatering of the lake shall be
a gradual process and the maximum rate of drawdown is 0.5' per day. During the lake drawdown
process contractor shall ensure the water being removed from the lake drawdown process
contractor shall ensure the water being removed from the lake into the river is free of sediment. If
sediment becomes a problem during the dewatering process contractor shall contact engineer
immediately.
13. Once the lake is lowered the contractor shall maintain minimum base flow at all times to the
Chattooga River of 0.5 CFS (7010 information taken from NSGS). The minimum base flow shall be
accomplished by using either mechanical pump or siphon system and shall remain in operation
throughout the dredging and refilling process.
14. Contractor shall install & stabilize construction entrances into lake bed.
15. Contractor shall install temp Sediment Basin #1 with all associated temp ditches and silt fence &
turbidity baffles prior to any activity within the lake bed.
16. Once contractor has appropriately installed temp sediment basin #1, Contractor shall begin installing
TD #1 to establish a new stabilized base channel with associated temporary crossings to allow all
upper basin base flow to bypass the dredging area.
17. Only after Contractor has established & stabilized temp ditch #1 shall contractor be allowed to
commence with any other activities within the lake bed.
18. All wetland area dredging shall be done in an upstream to downstream direction. This is so disturbed
sediment can be captured in the downstream wetland. Sediment curtains shall be used to isolate the
dredge and fill areas from open water.
19. Install silt fence and other measures as shown on plans, clearing only as necessary to install all
devices within the lake bed area.
20. Lake shall be dewatered to an elevation of 3467 after storm events as needed per sequence
described in item #14.
21. The contractor shall diligently and continuously maintain all erosion control devices and structures.
Erosion control measures should be checked periodically and after every rainfall event. Repairs shall
be made immediately as required. Inspection and repair reports shall be kept by the contractor and
provided to the state erosion control agent upon request.
22. Call geotechnical consultant for site inspection prior to grubbing or placing fill.
23. Contractor shall maintain one lane of traffic on Cashiers Lake Road (NCDOT SR 1113) at all times.
24. When site has been permanently stabilized, remove erosion control devices and apply permanent
seeding in area of disturbance.

25. Coordinate with erosion control inspector prior to removal of any erosion control measures.
26. Upon completion of the construction activities and stabilization the lake will be gradually refilled, this
will be accomplished by the contractor maintaining the minimum base flow at all times to the
Chattooga River of 0.5 CFS (7Q10 information taken from NSGS). The minimum base flow shall be
accomplished by using either mechanical pump or siphon system. Flows from the dam to the
Chattooga River must be maintained at all times at 70% of the incoming flow during Lake Refill.
Note: Erosion and sediment control measures shall be inspected daily and after any rainfall. Any
repairs or deficiencies shall be corrected immediately. A daily record log shall be maintained on
the site by the general contractor and will record any deficiencies and the corrective measures
taken. Installation of additional erosion and sediment control measures may be necessary if
requested by on-site inspection of NCDENR staff or the owners' representative of the engineer.
Reference the North Carolina Erosion and Sediment Control Manual sections 6.01-6.02 for
additional information.
Turbidity Monitoring Plan
The construction of this project will require in -water soil disturbing activities, which must meet the state's
water quality anti -degradation criteria. Lake Cashiers is located in the Chattooga River basin and is
considered an Outstanding Resource Water (ORW). The contractor shall meet the following conditions:
1. Contractor shall place (3) Turbidity sensors within the project limits. Existing ambient water quality
within the mixing zone may be degraded to allow for in -water construction activities. Turbidity levels
shall not average greater than ten (10) Nephelometric Turbidity Units (NTUs) above natural
background conditions at the discharge zone boundary
2. Ambient background samples shall be collected at the edge of ROW up stream of the existing
culverts at Frank Allen Road, free from the source of turbidity. The background sampling site will
be marked by stakes and shall be maintained for the duration of the sampling program. Background
samples will be collected from the up -current sampling location at the surface, mid -depth and one
foot above bottom. to water which is less than six feet deep, mid -depth samples are not required.
3. All construction activities that have a potential to create turbidity, such as dredging that require in -
water soil disturbance, shall require monitoring. Sampling shall commence prior to the start of
construction activities, and continue twice daily, with a maximum of four-hour intervals, during
ongoing potential turbidity creating construction activities. Samples shall be collected at all 3
locations simultaneously. The contractor is encouraged to reduce the disturbed are within the
dredging area to minimize the impacts of turbidity to the remaining waterbody.
4. All samples will be collected with a grab sampler (or inline pipe 1 floating buoy constant reporting
devices located in the following 3 designated locations thru-ought the project.
a. In-line device up stream from the headwaters of the dual culverts under Frank Allen Road
to collect water prior to entering lake dredge area.
b. Floating buoy device located near cold water intake/ siphon at damn outlet structure to
collect water leaving dewatering area.
c. In-line device designated to collect water samples downstream of dam.
Samples must be analyzed for turbidity as they are collected. The following information
must be recorded for each sample taken and submitted in a Monitoring Report.
5. In addition to the above mentioned, each Monitoring Report must include the following:
a. Site number;
b. Collector's name and affiliation
c. Date and time of day when sample was collected;
d. Sample collection depth and total depth;
e. Antecedent weather conditions, including wind direction and velocity; and,

f. Flow direction, if applicable.
6. In addition to the above mentioned, each Monitoring Report must include the following:
a. A statement of methodology including types of sampling equipment and
b. Analytical instrumentation, preservation, and handling;
c. Permit number;
d. A map indicating numbered locations of all sampling sites;
7. All turbidity monitoring reports shall be held onsite for Erosion Control inspector review and
submitted to the local Erosion Control office within (7) days of sample collection. All
correspondence should include the Permittee name and permit number. Failure to submit reports
in a timely manner constitutes a violation of the permit and may be grounds for revocation.
8. The Contractor shall comply with the following QA/QC requirements for each sample collected:
a. All turbidity analysis shall be performed on instruments that can perform Nephelometric
measurements;
b. The instrument must be calibrated each morning and each time the instrument is turned
on, and recalibrated every four hours thereafter;
c. Calibrations must be performed against a blank, and at least one formalin or gel -type
standard. The standard value should be in the same range as the sample readings.
d. All calibration procedures must be recorded in a permanent log book, and copies must be
submitted with the date; and,
e. Date and time of collection, date and time of analyses, and the name of the analyst must
be included in the log.
9. All in -water soil disturbing construction activities shall cease immediately whenever water quality
samples exceed thresholds specified in item #1 at the boundary of the discharge zone. The
violation shall be reported within 4 hours of the violation. The violation report shall include the
description of the corrective actions being taken or proposed to be taken. If violations are noted
after normal business hours, on holidays or on weekends, the report shall be made as soon as
possible after normal business hours resume. A copy of all monitoring data sheets, which indicate
violations, shall be forwarded immediately to the Erosion Control Inspector.
10. When turbidity violation is found, in -water soil disturbing construction operations may not resume
until a compliance inspection by District personnel has been conducted and a set of samples has
been taken which demonstrate that the water quality standards designated above are being
achieved.
11. Interim samples taken following the violation shall be taken in the same manner as the routine
monitoring and at the same locations. If samples demonstrate the water quality standards specified
for turbidity specified above are still being violated, sampling shall continue at two hour intervals
until the interim samples demonstrate that water quality standards are being achieved.
12. Failure to report violations and stop work and submit a corrective action plan to the local erosion
control inspector for approval before resuming work will constitute grounds for enforcement action
and may subject the Contractor to potential penalties

REPAIRIAN BUFFER GUIDELINE

Guidelines for Riparian Buffer
ReAOrafiOn
Department of Environment and Natural Resources
Division of Wafer Quality
Wetlan45 Restoration Program
Purpose ofthese Guidelines
Raleigh, NC
January 2001
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.

4+ Criteriafor Priority
Y
Riparian Buffer 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 3 5 inches diameter
at breast height) measured within
50 feet of intermittent and
perennial streams, lakes, ponds,
and shorelines.
�jr • 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.

A, Components ofa Riparian Buffer
Restoration/Enhancement Plan
McAssessment
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
Sit- prep.mation
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)
Elaeagntts umbellata (Autumn
Olive)
Hedera helix (English Ivy)
Lespedeza cuneata (Korean or
Sericea Lespedeza)
Liguslnon sinense (Chinese Privet)
Lonisera japonica (Japanese

Pueraria lobata (Kudzu)
Rosa mtrhflora (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 tut 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.
Agto565 alba (Redtop)
Found in fields, pastures, roadsides,
and other disturbed places
throughout North Carolina, this
native warm season grass should be
3
used sparingly for erosion control
and soil stabilization.
Ca►rxstricta (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.
plactylis ylomerata (0rchar4gra55)
This perennial, cool season
bunchgrass is a good alternative to
fescue because it is less competitive
and allows native herbs to colonize
the site.
Hordcum 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.
Panicum clandestioam (Deer
Tongue)
This native, perennial, warm season
bunchgrass can be used in moist low
woods primarily in the piedmont and
mountains.
Panicum 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.
Amicum viryaturn (Switchgrnss)
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.
Pennisetumghucum CBrown Top
or Pearl Millet)
This fast-growing, robust, annual
grass exhibits good drought tolerance
which makes this species an
important warn season option for
soil stabilization.
Ailarisarundinacm ([teed
Canarygrassl
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.
Secale cewle (VVi rater 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
4
during the late spring, a critical time
in the establishment of perennial
species. Winter rye germinates,
quickly and is tolerant of poor soils.
Sorghum bicolor(Sudangmss)
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.
