4. Project Description and History
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 Project area is comprised of one unnamed tributary, KJ1, split into three reaches based on proposed mitigation treatment (A, B, and C), that flows east to west and drains just
downstream of the project into Cowford Branch. The total drainage area for the Project is 238 acres (0.37 mi2). The surrounding land use is agricultural and undeveloped land with
scattered single-family homes. Drain tiles have been constructed to drain the surrounding slopes below the gently sloping to nearly level landscape along the edge of the interstream
divide. Primary land use within the Project drainage area consists of approximately 75% Row Crop, 21 % Woods, 3.3% Residential, and 0.06% Impervious Surface.
KJ1-A
Reach KJ1-A originates at an ephemeral/intermittent break, located at the confluence of 3 ditches on the eastern boundary of the proposed conservation easement. The reach has a
mild valley with limited longitudinal slope, has been historically ditched, and no longer provides significant ecological functions. KJ1-A flows west through row crop fields to KJ1-B. Much if
not all the reach's morphology is currently driven by ditching instead of natural channel processes. The break between reach A and B was selected because the valley steepens and
becomes more defined downstream of this point. Row crops are directly adjacent to both banks. Drain tiles from the adjacent fields currently outlet directly into the reach.
KJ1-B
Reach KJ1-B originates at downstream end of KJ1-A and flows west through hydric soils to a proposed culvert crossing and easement break. The reach has been ditched and has
further degraded such that it lacks floodplain connection, appropriate pattern, and bedform diversity. There is an existing 41 LF culvert crossing approximately in the middle of the
reach. Row crops are directly adjacent to both banks. Drain tiles from the adjacent fields currently outlet directly into the reach.
KJ1-C
Reach KJ1-C originates downstream of the proposed easement break and continues west to the downstream limits of the conservation easement. The reach has a relatively steep
(-1%), defined valley. Directly downstream of the easement, the channel flows under NC I-IWY 258 through a 48" CMP. The reach has been ditched and has further degraded and
entrenched such that it lacks floodplain connection, appropriate pattern, and bedform diversity. Managed forest, from an expired CRP easement, forms an immature buffer along much
of the right bank while row crops form much of the left bank.
Vegetation at the Project is made up of mainly brush species that grow along the banks of the ditches. These species include Muscadine (Vitis rotundifolia), Carex sp., Brazilian vervain
(Verbena brasiliensis), and Pokeweed (Phytolacca americana). The fields next to the ditches have been used as agricultural fields. Along the downstream end of KJ1-C, a buffer was
planted in 2004, funded by the United States Department of Agriculture (USDA), Farm Service Agency (FSA), Conservation Reserve Program (CRP). Ditch and stream buffer areas
were planted but no bank stabilization took place. In this CRP zone, the vegetation changes from small brush to larger trees. The canopy becomes more closed and includes species
like Persimmon (Diaspyros virginiana), Sawtooth Oak (Quercus acutissima), Loblolly Pine (Pinus teada), Southern Red Oak (Quercus falcate), Sugarberry (Celtis laevigata) and
Southern Crabapple (Malus angustolfia). The herbaceous layer in this closed canopy area consists of Chinese privet (Ligustrum sinense), Shrubby Lespedeza (Lespedeza bicolor),
Smooth Sumac (Rhus glabra), and Trumpet vine (Campsis radicans). Woody vines are also locally common and include Laurel Greenbrier (Smilax laurifolia).

4h. Explain the purpose of the proposed project:*
The purpose for this mitigation site is to restore aquatic resources in order to offset unavoidable impacts to the White Oak 01 watershed. The streams and wetlands proposed for
restoration have been significantly impacted by ditching, drain tiling, and other agricultural practices for over 50 years. The stream is currently allowing sediment, nutrients, pesticides,
and herbicides to flow freely into Cowford Branch and the New River. The proposed wetland restoration area will raise the local groundwater and restore a more natural hydrologic cycle
to the riparian zone. Successful construction and restoration of this tributary and headwater wetland system will provide numerous benefits to water quality. Proposed improvements to
the Project will help address impacts specifically discussed as priorities in in the 2010 White Oak River Basin Restoration Priorities (RBRP). Through stream restoration, headwater
valley (HWV) restoration, and wetland restoration, the Project presents 3,347 LF of proposed stream, generating 3,538.670 Warm Stream Mitigation Units (SMU) and 2.991 acres of
proposed wetland, generating 2.991 Wetland Mitigation Units (WMU).
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*

The treatment plan and design approach were developed based on existing conditions, project goals, and objectives. The Project will include stream and headwater valley restoration.
Stream restoration will incorporate the design of a single -thread, meandering channel, with parameters based on data taken from reference site, published empirical relationships,
regional curves developed from existing project streams, and NC Regional Curves. Analytical design techniques will also be a crucial element of the project and will be used to
determine the design discharge and to verify the design. Based on soil type, valley slope, and drainage area headwater valley restoration was incorporated in the design. Headwater
valley restoration will include the design of a vegetated diffuse flow system that will allow for the passive development of a headwater stream.
The detailed treatment plan and design approach is as follows:
Reach KJ1-A (HWV)
A headwater valley restoration approach is proposed for this reach to address historic ditching and buffer impacts. Restoration activities will include:
- Grading a headwater valley,
- Installing wood structures to provide grade control and habitat,
- Installing live stakes to stabilize the bed and banks,
- Riparian planting.
Reach KJ1-B
An offline restoration approach is proposed for this reach to address historic ditching and buffer impacts. Restoration activities will include:
- Grading a new, single -thread channel in the existing floodplain,
- Installing log structures to provide grade control and habitat,
- Establishing a riffle -pool sequence throughout the new channel,
- Installing toe protection on meander bends,
- Installing live stakes to stabilize the banks and provide channel shading,
- Riparian planting.
Reach KJ1-C
An inline, P2 restoration approach is proposed for this reach to address historic ditching, channelization, and buffer impacts. Restoration activities will include:
- Grading a new, single -thread channel in an excavated floodplain,
- Installing log structures to provide grade control and habitat,
- Establishing a riffle -pool sequence throughout the new channel,
- Installing toe protection on meander bends,
- Installing live stakes to stabilize the banks and provide channel shading,
- Filling the existing channel,
- Riparian planting, and
- Invasive vegetation treatment.
The Cowford Project offers a total ecosystem restoration opportunity. As such, the wetland restoration is closely tied to the stream restoration and drain tile interruption. The Project will
provide 2.991 WMUs through wetland re-establishment. Wetland re-establishment is only proposed in areas that have been determined appropriate for wetland restoration by a
licensed soil scientist due to the presence of hydric soils and potential hydrology. Re-establishment activities will include; a successful restoration that raises the local groundwater
elevation and allows frequent flooding, the plugging of ditches, removing all drain tiles within the easement, and creating shallow depression features in the wetland. These activities will
help raise the local groundwater and have a more natural hydrologic cycle in the riparian zone. Surface roughening through shallow soil ripping will improve infiltration and slow runoff
through the floodplain. Surface roughening will also create microtopography and shallowdepressional areas, re-establishing more natural conditions and establishing habitat diversity.
Fistoric land -use impacts will be addressed through the planting of a native hardwood wetland community.
A Coastal Plain Small Stream Swamp will be the target community along the Project reaches and wetlands. This community type represents a diverse group of species with differing
flood tolerances, able to grow in close association with one another along stream and wetland features. Additionally, as tree species are able to survive less frequently flooded
conditions than shown for their tolerance class, the planting plan selected takes into account the species that are best suitable for the most flooded zone of the project with the intention
that they will likely survive both the wetland area and the more upland conditions. The restoration of plant communities along the Project will provide stabilization and diversity. For rapid
stabilization of the stream banks (primarily outside meanders), silky dogwood (Cornus amomum), Cottonwood (Populus deltoides) and black willow (Salix nigra) were chosen for live
stakes along the restored channel because of their rapid growth patterns and high success rates. Willows grow at a faster rate than the species planted around them, providing faster
bank stabilization and contribution of organic matter to the channel than the other planted woody species. As the community matures, the willows will slowly stop growing or die out as
the other species outgrow them and create shade that the willows do not tolerate. The live stake species will be planted along the outside of the meander bends to three feet from the
top of bank, creating a three-foot section along the top of bank. The live stakes will be spaced at least one per three linear feet with alternate spacing vertically.
Treatment for invasive species will be required within all grading limits associated with stream restoration. Invasive species will require different and multiple treatment methods,
depending on plant phenology and the location of the species being treated. All treatment will be conducted as to maximize its effectiveness and reduce chances of detriment to
surrounding native vegetation. Treatment methods will include mechanical (cutting with loppers, clippers, or chain saw) and chemical (foliar spray, cut stump, and hack and squirt
techniques). Invasive or aggressive plants containing mature, viable seeds will be removed from the Project and properly disposed. All herbicide applicators will be supervised by a
certified ground pesticide applicator with a North Carolina Department of Agriculture and Consumer Services (NCDA&CS) license and adhere to all legal and safety requirements
according to herbicide labels, and NC and Federal laws.

3j. Comments:
All permanent stream impacts are due to the relocation of the stream reaches to the natural valley and to restore proper dimensions and profile to the
stream which will provide a net gain in the ecological function to the stream and wetland system. After stream relocation and restoration the total
ebsting length of stream will increase from 2,988 linear feet to 3,347 linear feet of stream. The project will provide an 359 feet of additional stream
length to the system.
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:
Due to the nature of the project, complete avoidance of stream and buffer impacts is not possible. Proposed stream impacts, including stream
relocation and bank stabilization, are necessary restoration practices that will contribute to the functional uplift of the Project's aquatic resources.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Impacts are minimized using a stage construction approach. Where possible, the channel will be constructed prior to turning stream flow into a
segment. This approach allows minimization of the impact of each stage during the project construction. Efforts will be made to preserve individual
high value trees located within the stream restoration area.
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?
OYes ONo
2b. If this project DOES NOT require Compensatory Mitigation, explain why:

This is a stream and buffer mitigation project which will provide functional uplift to the stream and buffers on site and therefore does not need compensatory mitigation.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
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?
CYes nNo

Dear Mrs. Browning:
RECEIVED
JUL 15 2019
RALEIGH REGULATORY
FIELD OFFICE
The U.S. Fish and Wildlife Service (Service) has reviewed the project advertised in the above
referenced Public Notice. The project, as advertised in the Public Notice, is expected to have
minimal adverse impacts to fish and wildlife resources. Therefore, we have no objection to the
activity as described in the permit application.
In accordance with the Endangered Species Act ref 1973,.as amended, (ESA) and based on the
information provided, and other available information, it appears the action is not likely to adversely
affect federally listed species or their critical habitat as defined by the ESA. We believe that the
requirements of section 7 (a)(2) of the ESA have been satisfied for this project. Please remember
that obligations under the ESA must be reconsidered if: (1) new information identifies impacts of this
action that may affect listed species or critical habitat in a manner not previously considered; (2) this
action is modified in a manner that was not considered in this review; or, (3) a new species is listed
or critical habitat determined that may be affected by the identified action.
For your convenience a list of all federally protected endangered and threatened species in North
Carolina is now available on our website at <http://www.fws.gov/raleigh>. Our web page contains a
complete and updated list of federally protected species, and a list of federal species of concern
known to occur in each county in North Carolina.
The Service appreciates the opportunity to review and provide comments on the proposed action.
Should you have any questions regarding the project, please contact Kathy Matthews at [phone],
extension 27.

P'fe Benjamin,

Subject: [EXTERNAL] RE: [External] Project Scoping: Federal -Aid project (FHWA lead federal agency) administered by NC
DMS in Onslow County
Date: Friday, July 26, 2019 3:50:48 PM
Mr. Mceachran,
I have looked at the site located off NC Hwy 258 near its intersection with NC Hwy 24 in Onslow
County for a NCDMS project of 3,770' potential stream and 2.27 acres of wetland restoration credits.
The area is associated with Cowford stream and is currently in agricultural use with minimal to no
buffer.
There appears to be no listed species within the immediate project area. However, since there was
minimal detail provided regarding site plans, it is difficult to say whether or not the project will
provide successful mitigation. Site design is important to insure water quality and wildlife benefits
can be obtained through the project by means of floodplain connectivity, appropriate vegetation,
and travel corridors. An important detail to consider is the downstream culverts under NC Hwy 258.
Generally the NCWRC provides comments during onsite meetings and during project proposals with
the IRT. More conversation may be had at that time when further details are provided.
Thank you for the opportunity to review and provide comment. If I can be of additional service,
please do not hesitate to call or email.

WHEN AND WHERE TO USE IT
SILT FENCE IS APPLICABLE IN AREAS:
WHERE TI1E MAXIMUM SHEET OR OVERLAND FLOW PATI1 LENGTH TO TI1E FENCE IS 100-FEET.
WHERE TI1E MAXIMUM SLOPE STEEPNESS (NORMAL [PERPENDICULAR] TO FENCE LINE) IS 211: 1 V.
THAT DO NOT RECEIVE CONCENTRATED FLOWS GREATER THAN 0.5 CFS.
DO NOT PLACE SILT FENCE ACROSS CHANNELS OR USE IT AS A VELOCITY CONTROL BMP.
CONSTRUCTION SPECIFICATIONS:
I . USE A SYNTHETIC FILTER FABRIC OF AT LEAST 95% BY WEIGHT OF POLYOLEFINS OR POLYESTER, WHICH 1S
CERTIFIED BY THE MANUFACTURER OR SUPPLIER AS CONFORMING TO THE REQUIREMENTS IN ASTM D 646 1 .
SYNTHETIC FILTER FABRIC SHOULD CONTAIN ULTRAVIOLET RAY INHIBITORS AND STABILIZERS TO PROVIDE A
MINIMUM OF 6 MONTHS OF EXPECTED USABLE CONSTRUCTION LIFE AT A TEMPERATURE RANGE OF 0° TO 1 20° F.
2. ENSURE THAT POSTS FOR SEDIMENT FENCES ARE I .33 LB/LINEAR FT STEEL WITH A MINIMUM LENGTH OF 5 FEET.
MAKE SURE THAT STEEL POSTS HAVE PROJECTIONS TO FACILITATE FASTENING THE FABRIC.
CONSTRUCTION:
I . CONSTRUCT THE SEDIMENT BARRIER OF EXTRA STRENGTH SYNTHETIC FILTER FABRICS.
2. ENSURE THAT THE HEIGHT OF THE SEDIMENT FENCE DOES NOT EXCEED 24 INCHES ABOVE THE GROUND SURFACE.
(HIGHER FENCES MAY IMPOUND VOLUMES OF WATER SUFFICIENT TO CAUSE FAILURE OF THE STRUCTURE.)
3. CONSTRUCT THE FILTER FABRIC FROM A CONTINUOUS ROLL CUT TO THE LENGTH OF THE BARRIER TO AVOID
JOINTS. WHEN JOINTS ARE NECESSARY, SECURELY FASTEN THE FILTER CLOTH ONLY AT A SUPPORT POST WITH 4
FEET MINIMUM OVERLAP TO THE NEXT POST.
4. EXTRA STRENGTH FILTER FABRIC WITH 6 FEET POST SPACING DOES NOT REQUIRE WIRE MESH SUPPORT FENCE.
SECURELY FASTEN THE FILTER FABRIC DIRECTLY TO POSTS. WIRE OR PLASTIC ZIP TIES SHOULD HAVE MINIMUM 50
POUND TENSILE STRENGTH.
5. EXCAVATE A TRENCH APPROXIMATELY 4 INCHES WIDE AND 8 INCHES DEEP ALONG THE PROPOSED LINE OF POSTS
AND UPSLOPE FROM THE BARRIER.
6. PLACE 12 INCHES OF THE FABRIC ALONG THE BOTTOM AND SIDE OF THE TRENCH.
7. BACKFILL THE TRENCH WITH SOIL PLACED OVER THE FILTER FABRIC AND COMPACT. THOROUGH COMPACTION OF
THE BACKFILL IS CRITICAL TO SILT FENCE PERFORMANCE.
8. DO NOT ATTACH FILTER FABRIC TO EXISTING TREES.
MAI NTENANCE:
I . INSPECT SEDIMENT FENCES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REQUIRED REPAIRS
IMMEDIATELY.
2. SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR BECOME INEFFECTIVE, REPLACE IT
PROMPTLY.
3. REMOVE SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND
TO REDUCE PRESSURE ON THE FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING CLEANOUT.
4. REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND BRING THE AREA TO GRADE AND
STABILIZE IT AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY STABILIZED.
