SUBJECT: Secondary Road Paving/Pipe replacement, SR 1885 (Selkirk Road), Cleveland County
Dear Mr. Lund:
The North Carolina Department of Transportation proposes to replace a pipe in conjunction with a
secondary road paving project on SR 1885 (Selkirk Road) in Cleveland County. The existing 35-foot, 81"
x 59" CMPA will be replaced with a 50-foot, 81"x 59" CMPA. The new pipe will be placed on a skew
to better align the upstream and downstream sections, which will result in the loss of 30 linear feet of
stream length. Approximately fifteen feet of new stream channel with arock-faced bench will be
constructed to connect the existing channel to the new pipe inlet. The new channel dimensions will be
based upon a reference cross-section surveyed approximately 70 feet upstream. Five feet of riprap will be
utilized at the new pipe outlet for structure stabilization. Surficial bedrock is evident in the project area;
therefore, the proposed pipe cannot be buried one foot below the streambed elevation. NCDOT proposes
to place the new pipe on the existing streambed grade. Due to the existing site conditions, NCDOT
requests a waiver from the Regional Condition 2(b)(e) permit depth specification, for the
construction of this project.
Temporary cofferdams and bypass pumping will be utilized to manage the stream during construction.
Upon project completion, the channel disturbed by the temporary cofferdams will be restored to pre-
project conditions and the area seeded and stabilized. The total scope of the work will result in 20 feet of
permanent impacts to unnamed tributary to Magness Creek, which is classified as a WS-IV watershed by
the Division of Water Quality.
The project is not located within Y2 mile of any critical watershed area nor is SR 1885 a rural or urban
arterial; therefore, hazardous spill basins are not required. Enclosed is the hazardous spill basin checklist.
Based upon correspondence with the State Historic Preservation Office (SHPO), dated 1/09/07, the
proposed project area has been reviewed and SHPO has determined that no historic properties will be
affected (ER Number 07-1973). This office has conducted a GIS and field survey for the project
threatened/ endangered species. The federally listed species for Cleveland County (USFWS listed dated

SR 1885, Selkirk Road
Page 2
March 4, 2008
March 8, 2006) include the dwarf-flowered heartleaf (Hexasrylis naniflora). Natural Heritage Program
records document the nearest dwarf-flowered heartleaf location ~2.9 miles northwest of the proposed
project area. The heartleaf is usually found on dry to moist ravine slopes (usually north facing and of the
oak-hickory-pine forest type) and in boggy areas near springheads. No heartleaf species were observed
and there appears to be limited suitable habitat within the proposed project area. NCDOT is
recommending a finding of "no effect" for T&E species.
I have enclosed apre-construction notification for a NW#14, sketches of planned activities, and location
maps relative to the project.
Project information for the 401 Automated Payment Procedure is as follows:
• Work order number: 150455-55120005-120.023083-3855
• TIP #: NA
• Project Category: $240.00 Fee
If you have any questions or concerns, please feel free to contact me at [phone]. Thank you for

Thirty feet of channel will be filled; fifteen feet of stream channel will be reconstructed using
natural channel design principles. Streambed material will be salvaged from the filled stream to
be used in the reconstructed channel.
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 January 15, 2002, 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
NCEEP 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://h?o.enr.state.nc.us/ncwetlands/strm~ide.html.

DATE February 25, 2008
DIVISION OF HIGHWAYS
DEPARTMENT OF TRANSPORTATION
STATE OF NORTH CAROLINA
W.O. # 120.023083

PURPOSE
The purpose of this Erosion and
Sedimentation Control Program of the Division
of Highways is to control accelerated erosion
and sedimentation resulting from the
construction and maintenance of roads and
highways in North Carolina. This program is
developed pursuant to the requirements
contained in the Rules and Regulations for
Erosion and Sedimentation Control which were
adopted by the North Carolina Sedimentation
Control Commission on April 10, 1974.

PROJECT
DESCRIPTION
SR 1885 (Selkirk Rd j from its intersection with SR 1801 to SR 1802. It will be
constructed to the attached typical section. No problem areas are anticipated. The
work will be completed during the 07/08 construction season.

CONSTRUCTTON SEQUENCE
I. Grading to be started by state forces. Install all necessary silt fences, sediment basins, and check dams
and begin clearing construction area.
2. Rough grade the construction area and begin installing any storm drainage and/or cross lines. Install
inlet and outlet protection as storm drainage is being installed.
3. As an area is brought to finish grade and the black base is placed for the road, and the shoulder
finished, then seed, mulch and tack should be provided for denuded areas.
4. Leave all erosion control devices in place until vegetation has been established sufficiently to
withstand erosion. DO NOT remove any erosion control devices until directed by the County
Engineer.
MAINTENANCE PLAN
1. All erosion and sediment control practices will be checked for stability and operation following every
runoff producing rainfall but in no case less than once every week. Any repairs will be made
immediately to maintain all practices as designed.
2. Sediment will be removed from behind the sediment fence when it becomes about O.S feet deep at the
fence. The sediment fence will be repaired as necessary to maintain a barrier.
3. All seeded areas will be fertilized, reseeded as necessary- and mulched according to the instruction in
the seeded specifications to maintain a rigorous, dense vegetative cover.
4. Outlet protection will be installed when outlets are installed. Filter fabric will be placed under the
entire stone section and will be repaired and replaced if damaged during any phase of construction.
5. Sediment will be removed from the basin when it reaches 1.0 foot below the emergency spillway. The
filter stone is to be cleaned or replaced when basin no longer drains properly.
GROUND COVER FOR SLOPES. FILLS AND OTHER GRADED AREAS
The angles for graded slopes and fills shall be no greater than the angle which can be retained by vegetative
cover or other adequate erosion control de~tioes or stnrctures.
Seeding should be done in accordance with the specifications for that season of the year.
Additional erosion control measures may be required depending on the actual field conditions.

COIR FIBER BAFFLE:
Description
Furnish material, install and maintain coir fiber baffles according to the details in the
plans or in locations as directed. Coir Fiber Baffles shall be installed in silt basins and
sediment dams at drainage outlets. Work includes providing all materials, placing,
securing, excavating and backfilling of Coir Fiber Baffles.
Materials
(A) Coir Fiber Mat
Matting: Provide matting to meet the following requirements:
100% coconut fiber (coir) twine woven into high strength matrix
Thickness - 0.30 in. minimum
Tensile Strength 1348 x 626 lb/ft minimum
Elongation 34% x 38% maximum
Flexibility (mg-cm) 65030 x 29590
Flow Velocity Observed 11 ft/sec
Weight 20 oz/SY
Size 6.6 x 164 ft (120 SY)
"C" Factor 0.002
Open Area (measured) 50%
(B) Staples
Provide staples made of 0.125 in. diameter new steel wire formed into a u shape not less
than 12" in length with a throat of 1 " in width.
(C) Posts
Steel posts shall be at least 5 ft. in length, approximately 1 3/8" wide measured parallel to
the fence, and have a minimum weight of 1.25 lb/ft of length. The post shall be equipped
with an anchor plate having a minimum area of 14.0 square inches, and shall be of the
self-fastener angle steel type to have a means of retaining wire and coir fiber mat in the
desired position without displacement.
(D) Wire
Provide 8-gauge wire strand of variable lengths.
Construction Methods

Place the coir fiber baffles immediately upon excavation of basins. Install three (3)
baffles in basins with a spacing of one fourth (I/4) the basin length and according to the
detail sheets. Two (2) coir fiber baffles shall be installed in basins less than 20 ft. in
length with a spacing of one third (1/3) the basin length.
Steel posts shall be placed at a depth of 2 ft. below the basin surface, with a maximum
spacing of 4 ft. Attach an 8-gauge wire strand to the steel posts at a height of 3 ft. with
plastic ties or wire fasteners. Install a steel post into side of the basin at a variable depth
and a height of 3 ft. from the bottom of the basin to anchor coir fiber mat. Secure anchor
post to the upright steel post in basin with wire fasteners.
The coir fiber mat shall be draped over the wire strand to a minimum of 3 ft. of material
on each side of the strand. Secure the coir fiber mat to the wire strand with plastic ties or
wire fasteners. Place staples across the matting at ends and junctions approximately 1 ft.
apart at the bottom and side slopes of basin. Overlap matting at least 6" where 2 or more
widths of matting are installed side by side. Refer to details in the plan sheets. The
Engineer may require adjustments in the stapling requirements to fit individual site
conditions.
Measurement and Payment
Coir Fiber Baffles will be measured and paid for by the actual number of linear feet of
coir fiber baffles which are installed and accepted. Such price and payment will be full
compensation for all work covered by this section, including, but not limited to,
furnishing all materials, labor, equipment and incidentals necessary to install the coir
fiber baffles.
Payment will be made under:
