Project Status: Complete
Monitoring Level required by COE and DWQ (404 permit/ 401 Cert ) Level 1 -3,
Monitoring Level 1 requires completion of Section 1, Section 2 and Section 3
Permit States NCDOT shall perform the following components of Level I monitoring twice
each year for the 5 year monitoring period (summer and winter) Reference photos, plant
survival, and visual inspection of channel stability If less than two bankfull events occur
during the first 5 years, NCDOT shall continue monitoring until the second bankfull event is
documented The bankfull events must occur during separate monitoring years In the event
that the required bankfull events do not occur during the 5 year monitoring period, the
USACE, in consultation with resource agencies, may determine that further monitoring is not
required
Section I PHOTO REFERENCE SITES
(Monitoring at all levels must complete this section)
Total number of reference photo locations at this site: 6 reference points, 2 photos at each
Dates reference photos have been taken at this site: 5/20/04, 11/1/04, 5131105, 3/20/06,
10/18/06, 2/28/07, 9/12/07, 2/12/08
Individual from whom additional photos can be obtained (name, address, phone):
Other Information relative to site photo reference
If required to complete Level 3 monitoring only stop here, otherwise, complete section 2
Section 2 PLANT SURVIVAL
Attach plan sheet indicating reference photos.
Identify specific problem areas (missing, stressed, damaged or dead plantings)
Some of the planted vegetation was cut down due to the power company maintaining vegetation underneath the
power lines
Estimated causes, and proposed/required remedial action
NCDOT does not propose to do anymore replanting at this stream relocation due to the fact that the power lines will
be maintained on a routine basis Some of the vegetation that was cut should re-sprout
ADDITIONAL COMMENTS Vegetation is dormant at this time Stream is vegetated with alder, dogwood,
maple, elderberry, sycamore, black willow, and thick herbaceous vegetation
If required to complete Level 1 and Level 2 monitoring only stop here, otherwise, complete section 3
Section 3 CHANNEL STABILITY
Visual Inspection: The entire stream project as well as each in-stream structure and bank
stabilization/revetment structure must be evaluated and problems addressed
Report on the visual inspection of channel stability Physical measurements of channel
stability/morphology will not be required Include a discussion of any deviations from as-built
and an evaluation of the significance of these deviations and whether they are indicative of a
stabilizing or destabilizing situation
The stream is stabilized for the Year 4 Winter Evaluation NCDOT will continue to monitor the stream

chemical integrity, including transport of the water and sediment produced by the
stream's watershed in order to achieve dynamic equilibrium'
? Stream Enhancement - Stream rehabilitation activities undertaken to improve water
quality or ecological function of a fluvial system Enhancement activities generally
will include some activities that would be required for restoration These activities
may include in-stream or stream-bank activities, but in total fall short of restoring one
or more of the geomorphic variables dimension, pattern and profile Any proposed
stream enhancement activity must demonstrate long-term stability
? Enhancement Level I - Mitigation category that generally includes improvements to
the stream channel and riparian zone that restore dimension and profile This
category may also include other appropriate practices that provide improved channel
stability, water quality and stream ecology Work will be based on reference reach
information
? Enhancement Level II - Mitigation category for activities that augment channel
stability, water quality and stream ecology in accordance with a reference condition
but fall short of restoring both dimension and profile Examples of enhancement level
II activities may include stabilization of streambanks through sloping to restore the
appropriate dimension and vegetating a riparian zone that is protected from livestock
by fencing, construction of structures for the primary purpose of stream bank
stabilization and, when appropriate, reattaching a channel to an adjacent floodplain
? Streambank Stabilization - The in-place stabilization of an eroding streambank
Stabilization techniques, which include primarily natural materials, like root wads and
log crib structures, as well as sloping stream banks and revegetatmg the riparian zone
may be considered for mitigation When streambank stabilization is proposed for
mitigation, the completed condition should be based on a reference condition Stream
stabilization techniques that consist primarily of "hard" engineering, such as concrete
lined channels, rip rap, or gabions, while providing bank stabilization, will not be
considered for mitigation An exception to this may be considered for short reaches
when mitigating for urban stream impacts
? Stream Relocation - Movement of a stream to a new location to allow an authorized
project to be constructed in the stream's former location In general, relocated
streams must reflect the dimension, pattern and profile indicated by a natural
reference reach/condition in order to be adequate compensation for the authorized
stream impact Relocated streams will generally require wooded protected buffers of
sufficient width (see buffer section) Relocations resulting in a reduced channel
length will generally require mitigation
'This definition of stream restoration describes a category of mitigation for use with
this guidance, rather than a generic definition of stream restoration
slope according to a reference reach and, when appropriate, reattaching to an adjacent
floodplam
