Dear Ms. Brown, Mr. Cilley, and Mr. Bigelow:
This letter is in response to the Pre-Construction Notification (PCN) you submitted to
the Wilmington District, Asheville Field Office on October 11, 2023, for a Department of
the Army Nationwide permit (NWP) verification. This project has been assigned the file
number SAW-2023-01991 and is known as Headwaters Trout Farm Storm Fred
EWP/StRAP Stream Stabilization. This file number should be referenced in all
correspondence concerning this project.
A review of the information provided indicates that the proposed work would include
the stabilization of 1,595 linear feet of the North Fork French Broad River using a
combination of stacked boulders, boulder/rock toe with vegetative geo-lifts, and
plantings. The project area for this determination includes a 2.8 acre(s) area which is
illustrated on the enclosed site plans/maps. The project/review area is located at 71
Headwaters Farm Road, at Latitude 35.24586 and Longitude -82.88329; in Balsam
Grove, Transylvania County, North Carolina.
We have determined that the proposed work is authorized by NWP 37 pursuant to
authorities under Section 404 of the Clean Water Act (33 U.S.C. § 1344). The proposed
work must be accomplished in strict accordance with the general permit conditions, any
regional conditions, the special conditions listed in this letter, the application materials,
and the enclosed plans. If the extent of the project area and/or nature of the authorized
impacts to waters are modified, a revised PCN must be submitted to this office for
written approval before work is initiated. Any violation of permit conditions or deviation
from your submitted plans may subject the permittee to enforcement action.
This verification is valid until March 14, 2026, unless prior to this date the subject
NWP(s) is suspended, revoked, or is modified such that the activity no longer complies
with the terms and conditions of this NWP. If you commence or are under contract to
commence this activity before the date that the relevant NWP is modified or revoked,
you will have 12 months from the date of the modification or revocation of the NWP to
complete the activity under the present terms and conditions of this NWP.

Project Specific Special Conditions:

1. No in-water work shall occur between October 15 and April 15 of any year to
minimize impacts to trout reproduction.

Activities subject to Section 404 (as indicated above) may also require an individual
Section 401 Water Quality Certification. You should contact the NC Division of Water
Resources (telephone [phone]) to determine Section 401 requirements.

This NWP verification does not preclude the necessity to obtain any other Federal,
State, or local permits, licenses, and/or certifications, which may be required.

If you have any questions related to this verification or have issues accessing
documents referenced in this letter, please contact Shannon Healy, Regulatory
Specialist of the Asheville Field Office at 828-271-7980 ext. 4233, by mail at the above

1.ALL WORK IN OR ADJACENT TO THE RIVER SHALL BE CONDUCTED SUCH THAT FLOW
DOES NOT COME IN CONTACT WITH THE DISTURBED WORK AREA.
2.CONSTRUCT A TEMPORARY IN-STREAM THAT DIRECTS FLOW AROUND THE WORK
AREA SUCH THAT FLOW DOES NOT INTERACT WITH DISTURBED EARTH AND
CONSTRUCTION MATERIALS.
3.IN-STREAM DIVERSION MAY BE CONSTRUCTED OF SANDBAGS, RIPRAP (NCDOT CLASS
B, OR EQUIVALENT), AND/OR EXISTING BED AND BANK MATERIAL APPROVED BY THE
ENGINEER.
4.CONSTRUCTION SHALL BE TIMED TO OCCUR DURING TIMES OF LOW FLOW.
5.CONSTRUCTION SCHEDULING AND STAGING SHALL BE TIMED TO MINIMIZE THE
AMOUNT OF TIME SPENT WORKING IN THE RIVER CHANNEL.
6.THE RIVERBANKS, IN-STREAM STRUCTURES AND WORK AREA MUST BE STABILIZED
AT THE END OF EACH DAY BEFORE THE TEMPORARY DIVERSION IS REMOVED AND
FLOW IS RETURNED TO THE FULL CHANNEL.
7.AFTER THE WORK AREA IS STABILIZED, REMOVE THE MATERIAL USED TO CONSTRUCT
THE TEMPORARY DIVERSION AND RETURN THE RIVERBED TO THE
PRE-CONSTRUCTION CONDITION.
8.IN-STREAM DIVERSION SHALL BE INSPECTED WEEKLY OR AFTER EVERY RAIN EVENT.
ANY NEEDED REPAIRS SHALL BE MADE IMMEDIATELY.

SCALE (17"X11"):
GENERAL RE-VEGETATION AND PLANTING NOTES
1. FINAL VEGETATION SPECIES SELECTION MAY CHANGE DUE TO
REFINEMENT OR SPECIES AVAILABILITY AT THE TIME OF PLANTING.
SPECIES SUBSTITUTIONS WILL BE COORDINATED BETWEEN THE BANK
MANAGER, ENGINEER AND PLANTING CONTRACTOR PRIOR TO THE
PROCUREMENT OF PLANT/SEED STOCK.
2. LARGER NATIVE TREE SPECIES TO BE PRESERVED WILL BE FLAGGED BY
THE ENGINEER PRIOR TO CONSTRUCTION ACTIVITIES. ANY TREES
HARVESTED FOR WOODY MATERIAL WILL BE UTILIZED TO PROVIDE BED
AND BANK STABILIZATION AND COVER OR NESTING HABITAT ON THE
FLOODPLAIN. ANY EXCESS WOODY MATERIALS MAY USED TO BACKFILL
OLD CHANNELS.
3. ALL DISTURBED AREAS WILL BE STABILIZED USING TEMPRORY AND
PERMERMANET SEEDING AS DEFINED IN THE SEEDING SCHEDULE AND
THE APPROVED E&SC PLANS.
4. SUPPLEMENTAL PLANTING ACTIVITIES MAY BE REQUIRED WITHIN
THE CONSERVATION EASEMENT.
TEMPORARY SEEDING AND MULCHING NOTES
5. TEMPORARY SEEDING AND MULCHING SHALL BE APPLIED TO ALL
AREAS AND ACCESS ROUTES DISTURBED DURING CONSTRUCTION.
6. ALL SEED AND SEED VARIETIES MUST BE FREE OF STATE AND
FEDERALLY LISTED NOXIOUS WEED SEED AND INVASIVE SPECIES.
7. ALL DISTURBED AREAS WILL BE SEEDED WITH TEMPORARY SEED AND
MULCHED WITH WHEAT STRAW. SEEDING WILL BE
PERFORMED USING A BROADCAST SPREADER. OTHER METHODS MAY
BE USED BUT MUST BE APPROVED BY ENGINEER IN ADVANCE OF
INSTALLATION.
8. MAINTENANCE OF SEEDED AREAS SHALL CONSIST OF WATERING,
WEED AND PEST CONTROL, FERTILIZATION, EROSION REPAIR,
RESEEDING, AND INCIDENTAL OPERATIONS AS NECESSARY TO
ESTABLISH A HEALTHY, VIGOROUS, WEED FREE AND DISEASE FEE
UNIFORM STAND OF GRASS. ALL AREAS WHICH FAIL TO SHOW A
UNIFORM STAND OF GRASS FOR ANY REASON SHALL BE TREATED
REPEATEDLY UNTIL A UNIFORM STAND OF AT LEAST 90% COVERAGE IS
ATTAINED WITH NO BARE AREA GREATER THAN FIVE (5) SQUARE FEET.
PERMANENT SEEDING NOTES
9. PERMANENT SEEDING SHALL OCCUR IN CONJUNCTION WITH
TEMPORARY SEEDING WHERE APPLICABLE. IDEALLY, PERMANENT
SEEDING SHALL OCCUR DURING THE PLANTING SEASON FOR EACH SEED
TYPE. AREAS FERTILIZED FOR TEMPORARY SEEDING SHALL BE
SUFFICIENTLY FERTILIZED FOR PERMANENT SEEDING; ADDITIONAL
FERTILIZER IS NOT REQUIRED FOR PERMANENT SEEDING.
10. ALL SEED AND SEED VARIETIES MUST BE FREE OF STATE AND
FEDERALLY LISTED NOXIOUS WEED SEED AND INVASIVE SPECIES.
11. THE CONTRACTOR SHALL LOOSEN THE SOIL TO A MINIMUM DEPTH
OF 4-INCHES AND GRADE TO A SMOOTH, EVEN SURFACE WITH A LOOSE,
UNIFORMLY FINE TEXTURE. THE AREAS TO BE SEEDED ARE THEN TO BE
ROLLED AND RAKED TO REMOVE RIDGES AND FILL DEPRESSIONS TO
MEET FINISH GRADES. THE CONTRACTOR IS TO LIMIT SUB GRADE AND
FINISH GRADE PREPARATION TO AREAS THAT WILL BE PLANTED
IMMEDIATELY. PREPARED AREAS ARE TO BE RESTORED IF ERODED OR
OTHERWISE DISTURBED AFTER FINE GRADING AND BEFORE PLANTING.
12. SEED SHALL BE SOWN WITH A SPREADER OR A SEEDING MACHINE.
SEED IS NOT TO BE BROADCAST OR DROPPED WHEN WIND VELOCITY
EXCEEDS 5 MPH. SEED SHALL BE EVENLY DISTRIBUTED BY SOWING IN
TWO DIRECTIONS AT RIGHT ANGLES TO EACH OTHER. WET SEED OR
SEED THAT IS MOLDY OR OTHERWISE DAMAGED IN TRANSIT OR
STORAGE IS NOT TO BE USED. AFTER BEGIN SOWN, THE SEED SHALL BE
RAKED INTO THE TOP 1/4 INCH OF THE TOPSOIL, LIGHTLY ROLLED, AND
WATERED WITH FINE SPRAY. SEEDED AREAS ON STREAM BANKS SHALL
BE PROTECTED WITH COIR FIBER MATTING.
ZONE 1: STREAMBANK
13. LIVESTAKES AND HERBACEOUS PLUGS LISTED IN THE PLANTING
SCHEDULE SHALL BE PLANTED IN OFFSET ROWS AT A DENSITY OF 4,840
STEMS PER ACRE (3.0' O.C.) FROM TOE OF THE RESTORED CHANNEL TO
2.0' OUTSIDE THE BANKFULL STAGE. HERBACEOUS PLUGS SHALL BE
PLANTED ALONG THE TOE OF THE CHANNEL IN THE OUTSIDE OF THE
POOL MEANDER BENDS.
ZONE 2: RIPARIAN BUFFER
WOODY SPECIES LISTED IN THE PLANTING SCHEDULE SHALL BE PLANTED
IN OFFSET ROWS AT A DENSITY OF 440 STEMS PER ACRE (10.0' O.C.)
FROM 2.0' OUTSIDE THE BANKFULL STAGE TO THE GRADING LIMITS.
EXACT PLACEMENT OF THE SPECIES SHALL BE DETERMINED BY THE
CONTRACTOR’S VEGETATION SPECIALIST PRIOR TO SITE PLANTING AND
BASED ON THE WETNESS CONDITIONS OF PLANTING LOCATIONS.
