financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Proposed. impacts are required to restore stream functions, as described in The Silver
Creek Stream Restoration Plan. Project will result in restoring, enhancing, and preserving
9,632 linear feet (LF) of stream along Silver Creek and three unnamed tributaries to Silver
Creek and an overall increase in stream length on the site from 9,216 feet to 9,632 feet.
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.
Page 9 of 12
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, 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 NCWRP 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://h2o. enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
See attached restoration elan: The Silver Creek Stream Restoration Proiect.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(919) 733-5208 to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http:l/h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:

UT1 and M 1
1. Contractor shall prepare stabilized construction entrances as indicated on plans.
2. The Contractor shall mobilize equipment, materials, prepare staging area(s) and stockpile area(s)
as shown on plans.
3. Construction traffic shall be restricted to the area denoted as "Limits of Disturbance" on the
construction plans.
4. The Contractor shall install silt checks and temporary sediment traps at locations indicated on
plans.
5. The Contractor shall install temporary silt fence around the staging area(s). Temporary silt fence
will also be placed around the temporary stockpile areas as material is stockpiled throughout the
construction period.
6. The Contractor shall install all temporary stream crossings as shown on plans. Ditches and stream
reaches on site will be left open during the initial stages of construction to allow for drainage and to
keep site accessible.
7. The Contractor shall begin excavation of the UT1 stream channel. Excavation shall begin at Station
10+00 and proceed in a downstream direction, continuing to the confluence with M1. The
Contractor will begin by excavating floodplain areas to design grades in all areas except within 10
feet of the top of existing stream banks.
8. The Contractor shall excavate the UTt stream channel, starting from the upstream end and working
downstream. All work shalt be done in the dry.
9. Once a section of stream has been excavated to design grades, in-stream structures, matting and
transplants shall be installed in that section per the direction of the EngineerlProjectMonager and
the channel made ready to accept flow.
10. Water will be turned into the new channel once the area around the new channel and the new
channel has been stabilized.
11. The Contractor shall begin work on M1 after completing the UT1 stream channel. The contractor
shall excavate bankfull benches and place in-stream structures moving upstream to downstream.
The Contractor shall not disturb any more section of stream than they can stabilize in one day.
12.Once a stream work in this phase is complete the Contractor will apply temporary seeding,
permanent seeding, and mulch to any areas disturbed during construction. Permanent seeding
mixtures shall be applied as shown on the vegetation plan. Temporary seeding shall be applied in
all areas susceptible to erosion (i.e. disturbed ditch banks, steep slopes, and spoil areas) such that
ground cover is established within 30 working days following completion of any phase of grading.
Permanent ground cover shall be established for all disturbed areas within 15 working days or 30
calendar days (whichever is shorter) fallowing completion of construction.
13. All areas should be seeded and mulched before leaving the project site. Remove temporary stream
crossings and any instream silt checks.
14. The Contractor shall plant woody vegetation and live stakes according to planting details and
specifications. They should complete the reforestation (bare root tree planting) phase of the project
and applied permanent seeding at the appropriate time of the year.
15. The Contractor shall insure that the site is free of trash and leftover materials prior to
demobilization ofequipmentfrom the site.
M3, M4, UT2 and UT3
1. Contractor shall prepare stabilized construction entrances as indicated on plans.
2. The Contractor shall mobilize equipment, materials, prepare staging area(s) and stockpile areas as
shown on plans.
3. Construction traffic shall be restricted to the area denoted as "Lim its of Disturbance" on the construction
plans.
4. The Contractor shall install silt checks and temporary sediment traps at locations indicated on plans.
5. The Contractor shall install temporary silt fence around the staging area(s). Temporary silt fence will
also be placed around the temporary stockpile areas as material is stockpil~f throughout the
construction period.
6. The Contractor shall install all temporary stream crossings as shown on plans. Ditches and stream
reaches on site will be left open during the initial stages of construction to allow for drainage and to
keep site accessible.
7. The Contractor shall begin work on the M3 stream channel at the upstream end working downstream.
8. Once a section of stream has been excavated to design grades, in-stream structures, matting and
transplants shall be installed in that section per the direction of the Engineer/Project Manager and the
channel made ready to accept Flow.
9. Water will be turned into the new channel once the area around the new channel and the new channel
has been stabilized.
10. The Contractor shall begin work on M4 after completing the M3 stream channel. The contractor shall
excavate bankfull benches and place in-stream structures moving upstream to downstream. The
Contractor shall not disturb any more section of stream than they can stabilize in one day.
11. Upon completion of the M4 stream channel, the Contractor shall begin work on the UT2 stream
channel. Excavation of the UT2 stream channel shall begin at the confluence with M4 moving
upstream. All work shall be done in the dry. Pump around equipment will be required between station
19+00 and the confluence with M4. The Contractor shall not disturb any area larger than the
Contractor can stabilize in one day. Once construction is upstream of station 19+D0, the pump around
equipment will no longer be needed. Construction shall continue in an upstream direction to station
10+00.
12. Upon completion of the UT2 channel, the contractor shall begin work on the UT3 stream channel.
Excavation shall begin at the confluence with UT3 and proceed in an upstream direction. All work shall
be done in the dry. Pump around equipments will not be required on this reach.
13.Once a section of stream has been excavated to design grades, in-stream structures, matting and
transplants shall be installed in that section per the direction of the Engineer/Project Manager and the
channel made ready to accept flow.
14. Water will be turned into the new channel once the area around the new channel and the new channel
has been stabilized.
15.Once a stream work in this phase is complete the Contractor will apply temporary seeding, permanent
seeding, and mulch to any areas disturbed during construction. Permanent seeding mixtures shall be
applied as shown on the vegetation plan. Temporary seeding shall be applied in all areas susceptible
to erosion (i.e. disturbed ditch banks, steep slopes, and spcil areas) such that ground cover is
established within 30 working days following completion of any phase of grading. Permanentground
cover shall be established for all disturbed areas within 15 working days or 30 calendar days
(whichever is shorter) following completion of construction.
16. All areas should be seeded and mulched before leaving the project site. Remove temporary stream
crossings and silt check at downstream end of project.
17. The Contractor shall plant woody vegetation and live stakes according to planting details and
specifications. They should complete the reforestation (bare root tree planting) phase of the project
and apply permanent seeding at the appropriate time of the year.
18. The Contractor shall insure that the site is free of trash and leftover materials prior to demobilization
of equipment from the site.
