JAMES H. TROGDON, III
SECRETARY
We are proposing to replace two (2) wet crossline pipes (located on Washboard Ln. in Caldwell
County) when the necessary permits are obtained.
The wet crossline pipes are at the following locations:
Station Descri tion
7+02 Old 40'x48" CSP New 60'x48" CMP
32+63 Old 40'x18" CSP New 88'x48" CMP
De-watering will be required for the wet pipe replacements.
Morris Creek and unnamed tributaries to Morris Creek are within the Catawba River Basin and
are classified as Class "C". We are requesting the necessary permits to proceed with this work.
Attached is the E&SC Plan packet, which includes the proposed erosion control and wet pipe
drawings. The Minimum Criteria Checklist is also included.
If you have any questions or need additional information, please let us know.

Erosion Control Schedule and Notes
EROSION CONTROL & PIPE INSTALLATION
TROUT BUFFER ZONE SEQUENCE
GENERAL E&SC NOTES
GR�UND STABILIZATION CHART
1. Generally, the order of installation of the
erosion control measures will be as follows:
A. Temporary silt basins shall be installed
before clearing and grubbing begins.
B. Silt fences and tem orary silt ditches
shall be installed a�er clearing and before grading.
C. Temp orary stone ditch checks with PAM or
wattIes with PAM shall be installed in all disturbed
areas as soon as the disturbance begins.
D. Final stone ditch checks or wattles shall be
installed as soon as ditch line is established.
E. Pipe outlet and inlet protection will be done
as soon as the pipe is mstalled.
F. Other permanent erosion control measures are to
be imp�lemented as soon as practical.
2. Temporary rock silt checks?typ e B will be spaced
by percent grade as shown in-the erosion control plan.
3. No. S stone, or equivalent� will be used in conjunction
with the temporary rock silt checks in locations where
water is leaving the project or entering a pipe.
4. All devices are to be cleaned out when half full.
5. Establish permanent vegetation per ground stabilization
chart.
SCHEDULE
Wet Pipe Installation Schedule and Notes
1, Prior to installing any E&SC measures identify
permit conditions and impact area limits.
2. Install erosion control devices.
3. Manage the water course. The pipe must be
placed in the dry. Install dewatering measures.
4. Remove material and existing pipe while limiting,
material and sediment from entering stream and
escaping the project.
5. Excavation of stream channel shall not exceed 10' on
either side of new pipe or culvert unless indicated on permit.
6. Per permit conditions for Corps of. Engineers
and the Wildlife Resources Commission, all pipes
in streams 48"or �reater must be buried 12" below
streambed elevation, Pipes less than 48"must be buried
with 20% of the diameter below streambed elevation.
7. Place the new pipe and compact backfill.
8. Install slope protection on the outlet and inlet ends
of the pipe. A1so complete installation of erosion
control measures and perform maintenance as needed
on existing measures.
9. Establish permanent vegetation per ground stabilization
chart.
Notes;
10. More infortnation on wet pipe installation can be found
For silt basin size see the attached erosion control plans. in the BMP manual section 4.2 "Pipe & Culvert
installation"
PAM is to be placed on all Typ e A checks and wattles in the erosion
control chain except for the final device in HWQ and Trout projects.

Site Area Descrlption Stablllzatlon Tlme Frame Stablllzatlon Tlme Frame Exceptions
Perimeter dikes, swales, ditches 7 days None

Slopes steeper than 3:1 7 days If slopes are 10 ft. or less in length and are
not steeper than 2:1, 14 days are allowed
Slopes 3:1 or flatter 14 days 7 days for slopes greater than 50' in lenght
All other areas flatter than 4:1 14 days None
(except for perimeters and HQW zones)
General Erosion Control Sequence & Notes for NC DOT
Projects in Trout Buffer Zones
1. Prior to installing any E&SC measures identify
permit conditions and impact area limits. Review
trout buffer variance approval conditions for
any special provisions.
2. All materials should be on the hand before work
is commenced.
3. Install EC devices
4. Work within the buffer zone should be sequenced
to minimize the length of time that disturbed areas
are exposed. Stream bank stabilization, which includes
the area from the edge of water to the top of bank, should
be phased so that each day's work is a completed work,
including provision of adequate ground cover.
5. Graded slopes and fills within the trout buffer zone will
within 7 calendar days of completion of any phase of
grading be planted or otherwise �rovided with temporary
or permanent ground cover, devices, or structures sufficient
to restrain erosion.
6. Graded slopes and fills within the trout buffer zone (excluding
road shoulders) shall be protected with rolled erosion control
product, bonded fiber matrix, or flexible growth medium after
seeding.
Notes:
Silt fence backed by woven wire, with a post spacing of 6 feet,
shall be used instead of standard silt fence in trout buffer zone.
Special sediment control fence shall be used in areas where
bedrock is encountered which�rohibits the proper anchoring
of fabric, and in low points o the silt fence in 3-foot sections
to allow for concentrated flows.
The disturbed areas within the stream buffer shall be restored
to native vegetation characteristic of an undisturbed buffer to
the extent practical upon completion of construction.
Flyrock protection such as blast mats should be provided for
blasting in close proximity to streams.
PAM is to be placed on all Type A checks and wattles in the
erosion control chain except for the final device in HWQ and
Trout projects.
