4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:*
The current condition of these two small streams and adjacent riparian area is very poor. Bank erosion is evident throughout the proposed project reach and active erosion continues to
erode multiple mass wasting banks at the site. The health of the riparian corridor is poor; little riparian buffer or bedform diversity is currently present. The land use surrounding the
proposed project consists mostly of pasture, hayland, and forests.

Yes No Unknown
4f. List the total estimated acreage of all existing wetlands on the property:
0
4g. List the total estimated linear feet of all existing streams on the property:
1200
4h. Explain the purpose of the proposed project:*
The landowner has been approved for an Environmental Quality Incentives Program (EQIP) contract with the US Department of Agriculture's Natural Resources Conservation Service
(NRCS) to stabilize and restore this stream and to plant native riparian vegetation. Currently, the streambanks are eroding causing impairment to water quality and instream aquatic
habitat. The proposed stream restoration project will restore about 672 feet of this stream by improving channel and bank stability, as well as installation of trees and shrubs to create a
riparian buffer consisting of native species.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The proposed stream restoration project will restore approximately 672 feet of two small tributaries with the goal of improving natural ecological conditions and streambank stability. The
stream will be restored by grading the channel and streambanks to a naturally stable morphology and adding native vegetation adapted to site conditions for bank protection and soil
strength. Natural channel design in -stream structures will be used to maintain grade control, enhance bedform diversity, and protect streambanks from erosive hydraulic forces. Erosion
control matting, live stakes, bare root seedlings, vegetation plugs, and temporary and permanent seeding will be established to support long term stream health. The project will have a
positive impact on the downstream watershed by reducing sediment loading and creating a shaded woody stream buffer to help maintain water temperature. Equipment used to construct
the project will include a tracked hydraulic excavator with a hydraulic thumb, loaders, and dump trucks/trailers.

Impacts to the 672 feet of stream channel include the installation of j-hooks, log steps, and constructed riffles. These structures are needed to maintain
grade, reduce shear stress along the streambanks, and to enhance bedform diversity. This will result in a long-term positive impact to instream aquatic
habitat.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Stream restoration is needed to achieve ecological objectives and to enhance water quality within the project reach and downstream receiving waters.
Impacts will be minimized by maintaining the existing channel and minimal existing buffer as much as possible.
lb. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Construction impacts will be minimized by limiting in -channel work to low -flow conditions and working in the dry as much as possible. Streambanks and
other disturbed areas will be stabilized as soon as possible using seed, straw, and biodegradable erosion control matting. Appropriately sized equipment
will be used to minimize soil compaction. Experienced stream restoration contractors will work efficiently to minimize the time of disturbance.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
Yes No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Compensatory mitigation is not required for activities authorized by NWP 27 since this activity will result in net increases in aquatic functions and services.
F. Stormwater Management and Diffuse Flow Plan (required by DWR) u
1. Diffuse Flow Plan
la. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?

SUMMARY OF PROPOSED PROJECT:
This stream restoration project will address instabilities along approximately 672 feet of
two small tributaries to the Middle Prong Roaring River. The channel is migrating
laterally in multiple meander bends. This process is actively eroding vertical mass
wasting banks throughout the proposed project reach. Instabilities exist throughout the
reach. Additionally, the stream does not hove adequate access to a floodplain.
The objective of the proposed project will be to use natural channel design
methodology to address the stream's dimension, pattern, and profile to improve
sediment transport and stop bank erosion. Pattern or alignment will be corrected to a
tolerable range and he/d in p/ace with multiple structures including bou/der steps, /og
steps, and j-hooks. These structures will also maintain a stable channel dimension
and profile created through construction activities. Native herbaceous and woody
vegetation will be installed to create a high quality riparian corridor

EROSION AND SEDIMENTATION CONTROL MEASURES
DURING PROJECT IMPLEMENTATION, BMPS/CONSERVATION MEASURES WLL BE IMPLEMENTED TO
REDUCE SEDIMENTATION INTO THE STREAM. EFFORTS WLL BE MADE TO LIMIT AND EXPEDITE
EQUIPMENT TIME IN THE STREAM CHANNEL. WHEN POSSIBLE, WORK WLL OCCUR FROM THE
STREAMBANKS. THE DESIGN ATTEMPTS TO MINIMIZE SEDIMENTATION AND OTHER POTENTIALLY
NEGATIVE IMPACTS THROUGH THE FOLLOWING PRACTICES:
1. EXCAVATION AND GRADING ON THE SITE IS BALANCED. NO EARTH SHOULD BE REMOVED
FROM THE LOD.
2. THE CONTRACTOR WILL BE REQUIRED TO STAGE AND STORE EQUIPMENT AND MATERIALS AT
LEAST 25 FEET FROM TOP OF BANKS.
3. EQUIPMENT WILL BE WELL -MAINTAINED, CLEANED PRIOR TO MOBILIZATION, AND CHECKED
DAILY FOR LEAKS OF PETROLEUM PRODUCTS.
4. FUELING WLL BE PERFORMED IN A CONTAINED AREA AWAY FROM SURFACE WATER.
5. THE CONTRACTOR WLL BE REQUIRED TO STAGE WORK SUCH THAT DISTURBED AREAS WLL
BE STABILIZED IN PHASES WITH SEEDING, MULCH AND BIODEGRADABLE (COIR) EROSION
CONTROL MATTING (WHERE APPROPRIATE).
6. ALL TREES, UTILITIES AND OTHER SITE FEATURES WILL BE PROTECTED UNLESS MARKED FOR
REMOVAL OR RELOCATION.
7. WORK IN THE STREAM CHANNEL SHALL BE CONDUCTED "IN THE DRY" TO THE EXTENT
POSSIBLE.
8. ALL WORK ADJACENT TO STREAM WATERS WILL BE CONDUCTED IN A DRY WORK AREA TO
THE EXTENT POSSIBLE.
9. TO THE EXTENT POSSIBLE, CONSTRUCTION WILL BE TIMED TO OCCUR DURING TIMES OF LOW
FLOW.
10.CONSTRUCTION ACTIVITIES SHALL NOT OCCUR IN THE CHANNEL DURING WET WEATHER OR
STORM FLOWS.
11.CONSTRUCTION SCHEDULING AND STAGING WILL BE TIMED TO MINIMIZE THE AMOUNT OF
TIME SPENT WORKING IN THE STREAM CHANNEL.
12.THE PROPOSED WESTERN STREAM CHANNEL CAN BE CONSTRUCTED AND STABILIZED
COMPLETELY IN THE DRY BEFORE WATER IS RELEASED INTO THE CHANNEL AND THE OLD
CHANNEL IS PLUGGED.
13.APPROPRIATELY SIZED EQUIPMENT WILL BE UTILIZED TO PREVENT EXCESSIVE COMPACTING
AND MINIMIZE CLEARING.

1. EROSION CONTROL MATTING IS USED TO PROTECT RECENTLY CONSTRUCTED
STREAMBANKS FROM EROSION. THE MATTING WILL REMAIN INTACT WHILE THE BANK
AND RIPARIAN VEGETATION MATURES, PROVIDING CRITICAL BANK PROTECTION.
2. BEFORE INSTALLING COIR FIBER MATTING, RAKE SOIL LEVEL, ADD TEMPORARY AND
PERMANENT SEED, FERTILIZER, LIME AND MULCH.
3. 700 GRAM COIR FIBER EROSION CONTROL MATTING SHALL BE PLACED ALONG THE
LENGTH OF THE NEW CHANNEL FROM THE TOE OF SLOPE OUT TO THE BANKFULL
ELEVATION.
4 SECURE COIR MATTING IN PLACE BY STAKING AND OVERLAPPING AT THE SEAMS WITH
A SHINGLE —TYPE METHOD SUCH THAT THE OVERLAPPING PIECE IS IN THE SAME
DIRECTION AND AS THE STREAM FLOW. ADDITIONAL STAKING SHALL BE APPLIED BY
THE CONTRACTOR AT NO ADDITIONAL COST IF THE MATTING SEPARATES FROM THE
SOIL MORE THAN ONE INCH UNDER A REASONABLE PULL.
5. THE ROOFING NAILS SPECIFIED IN THE DETAILS CAN BE SUBSTITUTED FOR HOOKED
STAKES OR ANY OTHER METHOD OF SECURING THE MATTING TO THE GROUND
APPROVED BY THE ENGINEER.
6 EROSION CONTROL MATTING CAN BE OMITTED ON GRADED BANKS AT THE DISCRETION

GENERAL RE —VEGETATION PLAN NOTES
1. SOIL PREPARATION ELEMENTS, TEMPORARY AND PERMANENT SEED AND GROUND
COVER SHALL BE SPREAD OVER ALL AREAS WITHIN THE LOD THAT ARE DISTURBED
DURING CONSTRUCTION.
2. THE LANDOWNER PREFERS THAT ANY REVEGETATION OUTSIDE OF THE RIPARIAN
PLANTING AREA CONSIST OF TALL FESCUE, LIME, AND FERTILIZER.
3. LIVE STAKES, BARE ROOT STOCK AND CONTAINERIZED PLANTS SHALL BE EVENLY
DISTRIBUTED THROUGHOUT THE RIPARIAN PLANTING AREA AS DIRECTED BY THE
ENGINEER.
4. ADJUSTMENTS TO THE VEGETATION PLAN SHALL BE MADE ONLY IF APPROVED BY THE
ENGINEER.
5. LONG-TERM SUCCESS OF THE PROJECT WILL BE DEPENDENT ON THE LANDOWNER'S
ABILITY TO MONITOR AND REMOVE BEAVERS FROM THE SITE, PROTECTION AND
PROMOTION OF TREE AND SHRUB ESTABLISHMENT, AND ELIMINATION OF INVASIVE
PLANTS.
BARE ROOTS
6. ALLOW BARE ROOTS TO SOAK IN WATER AN HOUR OR TWO BEFORE PLANTING. DO NOT
SOAK THE ROOTS FOR MORE THAN 24 HOURS.
7. DIG A PLANTING PIT THAT IS THREE (3) TIMES WIDER THAN THE TREE'S CURRENT ROOT
SYSTEM. SPREAD OUT ROOTS TO ENCOURAGE OUTWARD GROWTH.
8. KEEP THE TREE VERTICAL IN THE PLANTING PIT (PERPENDICULAR TO THE GROUND) SO
THAT IT GROWS STRAIGHT.
9. REFILL THE PIT WITH NATIVE SOIL (WHAT WAS REMOVED AT DIGGING TIME), AND ANY
OTHER SOIL AMENDMENTS.
10. GENTLY TAMP OUT ANY AIR POCKETS FROM THE SOIL ONCE THE PLANTING HOLE IS
FILLED.
LIVE STAKES
11. LIVE STAKES MUST BE DORMANT WHEN CUT. KEEP LIVE STAKES MOIST UNTIL PLANTING.
THE STAKE SHOULD BE PREPARED WITH THE BUDS POINTED UP, AND THE BOTTOM
SHOULD BE CUT AT AN ANGLE FOR EASY INSERTION INTO THE GROUND.
12. LIVE STAKES SHOULD BE PLACED WITH 3 TO a OF THE LENGTH OF THE STAKE BELOW
GROUND AND ANGLED DOWNSTREAM. ENSURE THE BASE OF THE LIVE STAKE WILL REACH
THE WATER TABLE.
13. INSERT LIVE STAKES POINTED BOTTOM END FIRST INTO THE STREAMBANK.
CONTAINER STOCK
14. STOCK SHALL HAVE BEEN GROWN IN A CONTAINER LONG ENOUGH FOR THE ROOT
SYSTEM TO HAVE DEVELOPED SUFFICIENTLY TO HOLD ITS SOIL TOGETHER ONCE
REMOVED FROM THE CONTAINER.
15. CONTAINER PLANTS WILL NEED TO BE WATERED REGULARLY AND PLACED IN SHADY
CONDITIONS UNTIL PLANTING OCCURS. CREATE PLANTING AREA FOR EACH PLANT AND
EXCAVATE PIT.
16. THE DIAMETER OF THE PLANTING PITS FOR EACH PLANT SHOULD BE AT LEAST TWO
TIMES THE DIAMETER OF THE ROOT MASS. SCARIFY THE PLANTING PIT PRIOR TO EACH
PLANT INSTALLATION.
17. SET PLANTS UPRIGHT IN THE CENTER OF THE PIT. THE BOTTOM OF THE ROOT MASS
SHOULD BE RESTING ON UNDISTURBED SOIL.
18. PLACE BACKFILL AROUND BASE AND SIDES OF ROOT MASS, AND WORK EACH LAYER TO
SETTLE BACKFILL AND TO ELIMINATE VOIDS AND AIR POCKETS. WHEN PIT IS
APPROXIMATELY 3 FULL, WATER THOROUGHLY BEFORE PLACING REMAINDER OF THE
BACKFILL. WATER AGAIN AFTER PLACING FINAL LAYER OF BACKFILL.
