Monitoring Summary Report 2010
Project Site
The BannerLowe Mitigation Project is located in Avery County, NC in the Town of Banner Elk.
The project is located south of Banner Elk on the west side of NC 184 (Tynecastle Road), in the
mountain ecoregion of North Carolina (Figure 1). The property at BannerLowes is composed of
a total of 29.3 acres bordering Tynecastle Road. Tynecastle Road is the major thoroughfare into
the Town of Banner Elk and the primary commercial corridor. This property has 720 feet of
road frontage on Tynecastle Road. Primary access to the tract is through the Lowes access drive
from Tynecastle Road. Secondary access is over a private road (Glove Factory Lane) adjacent to
the old Glove Factory land (south) and a private road (Stonebridge Lane) adjacent to a Car Wash
(north). Land use in the project vicinity is commercial along Tynecastle Road with residential
homes set back from the road. The property was formerly used for a residential home, barn and
agricultural pasture.
The project is located within the Elk River watershed of the Watauga River Basin. The site lies
in US Geological Survey (USGS) Cataloging Unit 06010103 of the Watauga River Basin (no
NCDWQ subbasin unit). The mitigation project involves three streams and two wetlands on the
property. There are two unnamed tributaries (Stream A & Stream B), with Stream A flowing
into the Elk River on the southeast side of the property. Stream B flows behind the Lowes Store
towards the north, eventually into the Elk River. These streams were headwater streams, with
drainage areas of 0.04 square miles for Stream A, and 0.1 square miles for Stream B. The Elk
River flows through the center of the project on the east side of the Lowes Store, paralleling
Tynecastle Road. The drainage area of the Elk River is 2.95 square miles, and is a second order
stream at the project site. The Elk River was approximately six feet wide and six inches deep
with a cobble, gravel, and sand substrate. The river has experienced impacts from beaver
activity and floods (March 2003 and September 2004), resulting in bank and channel
degradation. Preconstruction conditions are documented in the previous monitoring reports.
The pattern, profile and dimension were restored for the three streams within the project site.
Prior to the project, the three streams had problems related to the existing conditions (primarily
agricultural) on the site. The Elk River was impacted by beaver dams, livestock watering access,
and then by floods in late 2004. Stream A was a perennial stream with its headwaters upstream
on the adjacent property. Stream A was channelized through the pasture on the property and was
impacted by livestock usage. Stream B began as a seep in the rhododendrons, intermittent flow
to the wetland areas, and was a perennial stream below the confluence of the wetland tributaries.
Stream B had been channelized, was heavily impacted by livestock use, and very little riparian
vegetation existed prior to the project. All three streams were in need of stream restoration to
stabilize the channels and improve the water quality of the streams.

The project restored the lower portion of the Elk River for a total of 4091f to a stable pattern,
dimension and profile and connected the stream hydrology with the riparian wetland restored
adjacent to the Elk River. Stream A was relocated to the south side of the property and restored
for a total length of 5921f. Stream B was an intermittent stream upstream of the property and
became a perennial stream downstream at the confluence with two unnamed tributaries draining
the springs west of the property. Stream B was relocated behind the current Lowe's Store
location and restored to a length of 1,0961f. Buffers for all three streams were restored and
planted and protected under a Conservation Easement to be held by Avery County.
The restoration project included two wetlands located adjacent to the Elk River on the east side
of the river. The project to date has restored several wetlands on the project site for a total of
0.65 wetland mitigation credits.
There were no comments made by state and federal agencies on the 2009 report. This 2010
report will summarize the stream restoration credits completion; and the replanting and regrowth
of the buffer areas and the stream and wetland vegetation survival.

BannerLowe Wetland Restoration and Creation
The BannerLowe 404 permit #200330365 and 401 certification DWQ#03-1134 issued in 2004
required mitigation of a total impacted area of 0.731 acres (COE permit) of wetlands adjacent to
the Elk River. As noted in the 2009 report, the COE determined that the 0.65 wetland credits
would be accepted and no additional wetland mitigation would be required. Additional scrub-
shrub vegetation was requested for the wetlands.
Vegetation Survival Success in Wetlands
Additional livestakes of silky dogwood, silky willow and black willow were planted in March
2010 around both Wetland #1 and Wetland #2. Survival of these livestakes was monitored in
August 2010 and had 93%-100% survival rates. Livestakes survival of the new and the original
plantings on the edges of the wetlands was high and beginning to spread out during this second
year of normal rainfall. As shown on the photographs in Appendix A, herbaceous wetland
vegetation was heavy in the wetlands and continued growth of shrubs was observed. The
wetlands are still primarily an emergent wetland habitat in Wetlands #1 and #2 and scrub-shrub
wetland habitat is developing along the drier edges of both wetlands and along the rocky Elk
River berms.
There has been complete success in the herbaceous wetland vegetation, which has been in place
since shortly after the wetlands were completed as shown in the previous monitoring report
photographs of the wetlands. Visual assessment of the vegetation in the wetlands will continue
for an additional year to monitor the additional livestake growth.
BannerLowe Stream Restoration and Relocation
Stream Mitigation
Stream A and Stream B are very low flow streams, and the uppermost section of Stream B has
been dry during the summer months as noted in the previous monitoring surveys. In March
2010, Stream B was observed to have a constant flow. A stream identification assessment was
performed and the stream was classified as intermittent. The stream identification form and
photographs of Stream Bin March 2010 can be seen in Appendix B. It was also noted that
several springs had appeared in and near the stream channel of the upper section of Stream B and
they should help to continue to improve the hydrology of this stream channel as the region's
groundwater table continues to recover from the droughts of 2007-2008. As noted in August
2010 monitoring photographs, the upper stream and the springs dry up during the summer
months.
The relocation of Stream A has restored the pattern, dimension and profile of the perennial
stream channel for a total of 592 linear feet as of 2009. The relocation of Stream B has restored
the pattern, dimension and profile of 1096 linear feet of intermittent or perennial flow. The Elk
River project restored the pattern, dimension and profile from the access bridge to the
downstream bridge on Stonebridge Lane for a total of 409 linear feet restored. The total stream
length restored and protected added up to approximately 2,0971f of stream credits in 2010.
The morphology of all of these streams has remained stable during both dry and wet seasons
since construction was completed in 2005. There were some structure changes in the Elk River
section but this did not impact the stability of the restored section. The Elk River structures can
be seen in the photograph in Appendix A.
Stream Buffer Vegetation
Vegetation has been an ongoing problem for some of the stream buffer areas, particularly during
the drought years of 2007-2008. As noted in past monitoring reports, these areas have required
additional plantings and efforts to protect the plantings from inappropriate landscaping. The
drought conditions in the region did not help the survival or the growth of the previous plantings.
In March 2010, additional tree plantings were done in the areas needing additional larger tree
species (See Photographs in Appendix Q. This year was the second year of normal or close to
normal rainfall for the Banner Elk area. Most of the project area ranged from good to excellent
growth of trees, shrubs and herbaceous species, responding to the improved moisture conditions.
Stream A:
Stream A did not experience any encroachment of mowing during the past year and the large
mature trees planted in 2009 have all survived. The fencing has provided a barrier and visual
delineation so that landscaping efforts have remained out of the buffer for the past year. Along
Stream A, the vegetation is healthy and well developed, with rushes, silky willow, black willow
and silky dogwood shrubs growing along the channel. Where water is concentrated in pools
below drops, the shrubs and herbaceous vegetation are heavy. As noted in past reports, the only
area with reduced stem counts was in the lower monitoring plot itself. This monitoring plot had
additional trees planted in March 2010 to bring that plot over the required number of stems. A
few additional trees were planted in the upper section of Stream A to improve the tree growth
behind the chain link fence. The rest of the Stream A buffer has continued to survive and
become established as can be seen in the photographs in Appendix A. No problems were
observed in the buffer or stream channel of Stream A in 2010.
The Lower Monitoring plot on Stream A was documented with a survival rate of 12 planted
stems and a total of 19 stems in the monitoring plot. This resulted in a total of 380 stems/acre for
the lower monitoring plot (See Figure 2). The plot was replanted with birches nearer the stream
channel and red oak and red maple on top of the berm away from the channel in March 2010.
Survival of all planted trees is 75% at this point (including the initial plantings which had poor
survival). Herbaceous cover in the plot is extensive and the stream channel in this section has
well established livestake growth along the channel itself and within the buffer. This can be seen
in the photographs shown in Appendix A.
The Upper Monitoring Plot on Stream A continued to show improvement, with some resprouting
and additional native/volunteer stems (See Figure 3). The monitoring shows 10 planted stems
and a total of 15 stems in the monitoring plot. The removal of landscaping activity on this plot
was observed in the condition and growth of the stems and herbaceous cover in this area. The
6
monitoring shows a total stem count of 300 per acre. This includes the larger, 5-8 year old trees
planted and established in 2009.

stream B
Stream B has had good cover and growth of herbaceous and shrubs in the lower section of the
stream, below the confluence with the two springs/wetland area. Initial tree growth was reduced
or did not survive during the drought years of 2007-2008 in scattered sections of the buffer along
Stream B as noted in past monitoring reports. The upper section of Stream B where the project
experienced difficulties in getting vegetation of any type in previous years was reseeded, matted,
mulched, fertilized and amended as needed. This area was replanted with 30 tree stems in March
2010. The seed mixture was recommended by NC Wildlife Resource Commission staff as being
the best native grass for establishing ground cover on the project. The additional hydrology
noted in March 2010 in the upper section of Stream B has helped to improve the viability and
growth of permanent vegetation. A total of 60 trees were planted in March 2010 throughout the
Stream B buffer.
The lower section of Stream B has more vegetation as it has a more constant source of water
from the wetland seeps. The Lower Monitoring Plot of Stream B shows 5 planted stems
surviving and a total of 8 stems in the monitoring plot, a loss of one stem from 2009 (See Figure
4). The monitoring shows a total stem count of 160 per acre. Herbaceous cover was excellent in
the lower monitoring plot in 2010 as can be seen in the photographs in Appendix A. There have
been some trees that resprouted after dying back during the dry summers of 2007-2008. The
replanting of stems did not add any additional stems to the Lower Monitoring Plot in March
2010, so additional stems will be planted fall/winter of 2010-2011 within the plot itself. The rest
of the buffer in the lower section of Stream B showed good recovery and growth.

Elk River Restoration
As noted in past reports, additional trees were requested along the Elk River downstream of the
access bridge. This was addressed in March 2010 with the planting of 100 tree stems of river
birch, northern red oak, red maple, and sycamore on the west side of the Elk River. These trees
appeared to be surviving and growing during the survey in August 2010. Additionally, the
existing birch trees (10) that were holding on from the initial plantings in 2005-2006 are still
surviving and beginning to put on height. Currently, most of the tree stems were covered by
herbaceous growth in the summer months because their height (2'-3') was shorter than the
herbaceous growth (3'-5'). All of the vegetation will help to develop a soil base on the exposed
river rocks that were deposited in the stream valley during the flood of 2004. Excellent shrub
and herbaceous cover along the Elk River can be seen in the photographs in Appendix A.
Stream Conclusion
One additional year of vegetation monitoring will be scheduled to monitor the vegetation plots
on Stream A and Stream B to confirm full recovery and survival. Visual surveys will be made of
the trees in the buffers, particularly the Elk River buffer, to document the growth of the newly
planted trees. Livestakes around the wetlands will be observed and documented as to the
recovery of the scrub-shrub edge around the marsh wetlands. The stream credit concern in past
reports has been addressed by the documentation of at least intermittent hydrology in the upper
section of Stream B.

Monitoring Summary Report 2009
Project Site
The BannerLowe Mitigation Project is located in Avery County, NC in the Town of Banner
Elk. The project is located south of Banner Elk on the west side of NC 184 (Tynecastle Road),
in the mountain ecoregion of North Carolina (Figure 1). The property at BannerLowes is
composed of a total of 29.3 acres bordering Tynecastle Road. Tynecastle Road is the major
thoroughfare into the Town of Banner Elk and the primary commercial corridor. This property
has 720 feet of road frontage on Tynecastle Road. Primary access to the tract is through the
Lowes access drive from Tynecastle Road. Secondary access is over a private road (Glove
Factory Lane) adjacent to the old Glove Factory land (south) and a private road (Stonebridge
Lane) adjacent to a Car Wash (north). Land use in the project vicinity is commercial along
Tynecastle Road with residential homes set back from the road. The property was formerly
used for a residential home, barn and agricultural pasture.
The project is located within the Elk River watershed of the Watauga River Basin. The site lies
in US Geological Survey (USGS) Cataloging Unit 06010103 of the Watauga River Basin (no
NCDWQ subbasin unit). The mitigation project involves three streams and two wetlands on the
property. There are two unnamed tributaries (Stream A & Stream B), with Stream A flowing
into the Elk River on the southeast side of the property. Stream B flows behind the Lowes Store
towards the north, eventually into the Elk River. These streams were headwater streams, with
drainage areas of 0.04 square miles for Stream A, and 0.1 square miles for Stream B. The Elk
River flows through the center of the project on the east side of the Lowes Store, paralleling
Tynecastle Road. The drainage area of the Elk River is 2.95 square miles, and is a second order
stream at the project site. The Elk River was approximately six feet wide and six inches deep
with a cobble, gravel, and sand substrate. The river has experienced impacts from beaver
activity and floods (March 2003 and September 2004), resulting in bank and channel
degradation. Preconstruction conditions are documented in the previous monitoring reports.

The pattern, profile and dimension were restored for the three streams within the project site.
Prior to the project, the three streams had problems related to the existing conditions (primarily
agricultural) on the site. The Elk River was impacted by beaver dams, livestock watering
access, and then by floods in late 2004. Stream A was a perennial stream with its headwaters
upstream on the adjacent property. Stream A was channelized through the pasture on the
property and was impacted by livestock usage. Stream B began as a seep in the rhododendrons,
intermittent flow to the wetland areas, and was a perennial stream below the confluence of the
wetland tributaries. Stream B had been channelized, was heavily impacted by livestock use,
and very little riparian vegetation existed prior to the project. All three streams were in need of
stream restoration to stabilize the channels and improve the water quality of the streams.
The project restored the lower portion of the Elk River for a total of 4091f to a stable pattern,
dimension and profile and connected the stream hydrology with the riparian wetland restored
adjacent to the Elk River. Stream A was relocated to the south side of the property and restored
for a total length of 5921f. Stream B was an intermittent stream upstream of the property and
became a perennial stream downstream at the confluence with two unnamed tributaries draining
the springs west of the property. Stream B was relocated behind the current Lowe's Store
location and restored to a length of 1,0961f. Buffers for all three streams were restored and
planted and protected under a Conservation Easement.
The restoration project included two wetlands located adjacent to the Elk River on the east side
of the river. The project to date has restored several wetlands on the project site for a total of
0.65 wetland mitigation credits.
There have been various levels of success in the mitigation of the stream and wetland impacts
on the BannerLowe site. During 2009, meetings on site, letter and phone discussions, and data
on the conditions on the site were exchanged between DWQ, COE and FWA. Some monitoring
requirements were dropped and other requirements were added to the project in order to fully
achieve mitigation success. This report will summarize the comments from the agencies over
the year and the conclusions reached addressing the 404/401 permit requirements and the future
plans and monitoring.

BannerLowe Wetland Restoration and Creation
The BannerLowe 404 permit #200330365 and 401 certification DWQ#03-1134 issued in 2004
required mitigation of a total impacted area of 0.731 acres (COE permit) of wetlands adjacent to
the Elk River as per Table 1 below.

Table 1. Wetland Impacts and Mitigation Table for BannerLowes Project, Actual Final
Mitigation, July 2009.
The 0.50+ acres of existing wetlands have been preserved through the protection of Wetland #5
on the west side (on hillside above Lowe's Store) and the protection of Wetland #1 along
Stonebridge Lane. Both of these wetlands are covered under the Conservation Easement for the
project site. The two wetlands on the east side of the Elk River were to provide a total of 0.55
restored acres with an additional 0.82 of created acres combined in the same wetlands for a total
of 1.37 acres for mitigation of wetland impact. The 0.82 acres was measured in April 2009,
during normal spring conditions.
The two restored wetlands have been monitored for hydrologic conditions for over three years
since being constructed. The current groundwater gage data, crest gage, stream height and rain
gage data are shown in Appendix A. The data shows that the wetlands meet the hydrologic
criteria, primarily from the water table during the summer growing season. During 2009, all
gages except GW 1 showed groundwater elevations 12" or above during the growing season.
GW 1 gage is not representative of the groundwater conditions in the area and will be dropped
from consideration. The groundwater elevations show additional hydrologic inputs from the
stream during high flow events. Hydric soils and vegetation have been documented in past
monitoring reports.
Additional wetlands have formed naturally on the project site in addition to the constructed
wetlands. A wetland has formed naturally on the west side of the Elk River across from Wetland
#1. This Wetland #3 was delineated in April 2009 and contains 0.23 acres of wetland. A fourth
wetland has formed on the west side of the lower Elk River, across from Wetland #2 and
contains 0.03 acres. Riparian wetlands are forming within the streambank channels of all three
streams on site, for an additional 0.05 acres or more of wetlands restored or created on site. With
these additional wetlands, the project has generated 0.65 credits for wetland mitigation. This
was short of the required 0.73 mitigation credits. Based on the quality of the restored and
created wetlands (high) compared to the pre-impacted wetlands quality (poor), the COE
determined in July 2009 that no additional wetland mitigation would be required (See attached
final determination document in Appendix B).
Vegetation Survival Success in Wetlands
The NCDWQ letter of February 25, 2009 (Appendix C) noted that the survival of woody
vegetation has been poor. As discussed with field personnel from DWQ and COE in April 2009,
the hydrologic conditions in these wetlands was so wet that an emergent wetland habitat has
formed in Wetlands #1 and #2 and not the scrub-shrub wetland habitat that was originally
proposed. Many of the reference wetlands in the Elk River Valley that were located prior to the
project were emergent wetlands, indicating a common habitat in the area. The monitoring plots
are primarily within this wetter regime, and FWA believes there will be few if any woody stems
possible in the existing monitoring plots and only live stake shrubs at best at the edge of the plots
that are within the conservation easement. There has been extremely successful growth of
herbaceous wetland vegetation offsetting the limited growth of woody stems.
The original live stakes installed in the wetlands did not survive due to very wet conditions.
Additional live stakes have been planted on the edges of the wetlands and are having varying
degrees of survival due to two years of drought and'/z year of normal rainfall. Most of these
shrubs cannot be seen except in close up field surveys during the growing season as they are only
1' to 2' tall. Some areas may need additional live stakes, but growth will occur from existing
plants once weather conditions return to average conditions.
FWA concurs with the DWQ letter that only the second year of vegetation growth in the
wetlands was documented in 2008 and future years should show a better success of live stake
growth and survival. There is complete success in the herbaceous wetland vegetation, which has
been in place since shortly after the wetlands were completed as shown in the previous
monitoring report photographs of the wetlands. Monitoring of the vegetation in the wetlands
will continue for an additional 2 years and replanting as noted in the replanting section below.

BannerLowe Stream Restoration and Relocation
Morphology
Stream A and Stream B are very low flow streams, and the uppermost section of Stream B was
dry during the summer months of the past two years (drought conditions). The relocation of
Stream A has restored the pattern, dimension and profile of the perennial stream channel for a
total of 592 linear feet as of 2009. The relocation of Stream B has restored the pattern,
dimension and profile of 748 linear feet of perennial flow. As the water table returns to normal
elevations and the region experiences normal rainfall, the dry channel in the upper Stream B
should return to intermittent stream conditions. The Elk River project restored the pattern,
dimension and profile from the access bridge to the downstream bridge on Stonebridge Lane for
a total of 409 linear feet restored. The total stream length restored and protected added up to
approximately 2,0141f of stream credits in 2009, with an additional 25 if to be found or
documented on site.
The morphology of all of these streams has remained stable during both dry and wet seasons
since construction was completed in 2005 and as was noted in the DWQ letter of February 25,
2009 for Streams A & B. As discussed during email communications with NCDWQ in 2009, it
was stated that if flow does not return to the upper Stream B channel, then additional stream
mitigation will be required for the acceptance of the mitigation project (Appendix Q. Stream
length will be monitored over the next two years to document the total amount of linear footage
of stream restoration present at the end of the project.
Additional monitoring of the morphology will not provide any additional information on the
success of these stream relocations; therefore monitoring of the morphology was proposed to be
dropped. This was discussed with staff with US COE and NC DENR during 2009 and
concurrence was reached that no additional morphology monitoring of Stream A, Stream B and
the Elk River will be required (Appendix C-Emails).
Vegetation
Vegetation has been an ongoing problem. All vegetation growth in the Banner Elk area has been
slow or diminished due to the drought conditions of the past three years in the region. Planted
trees and shrubs that have survived are generally the same size as when they were planted in
2004. This spring of 2009 has shown more growth and vigor in the buffers than has been seen in
the past; so hopefully with a return to normal rainfall patterns, future growth will show better
results.
Stream A
Stream A has experienced encroachment in the buffer due to the landscaping activities on the
north side of the stream. However, the monitoring data for this area (Stream A Upper
Monitoring Plot) for 2009 shows a success criteria of 11 stems, one over the required 10 stems
for the plot, despite this impact (Figure 2).
Nevertheless, the buffer has been impacted and steps were taken to resolve this situation. In May
2009, the area adjacent to the parking lot was fenced and a total of thirty 3-5 year old trees were
planted. The tree survival will be guaranteed for one year through the winter of 2009-2010.
This will provide the additional growth and height of trees that was lost from the impacts over
the past several years, and allow for the natural growth of existing stems. Lowes store
management was contacted and a site survey with Lowes staff and their landscaper was
performed, reviewing the buffer alignments and discussing flagging and no mowing areas. This
was documented on May 8, 2009 in emails to NCDWQ staff and USCOE staff (See photographs
of replanted area in Appendix D).

Project, Banner Elk, NC, 2009.
The south side of the stream has been experiencing slow growth, but is basically vegetated
throughout the buffer length with occasional bare ground spots due to the drought. However, the
monitoring plot data for this side (Figure 3) is below the success criteria and needs additional
tree plantings. Considering the numerous trees and shrubs within the rest of the buffer on the
south side of Stream A, this lack is only in the monitoring plot itself (See Appendix D). The
initial lack of tree survival in this area was due to ATV activities during the first year of
establishment of the buffer in 2004-5. This problem was addressed and the area replanted after
the ATV trail was shut down. The current lack of trees is probably due to the berm like
condition in this area that created drier conditions than the rest of the buffer. This in turn
resulted in the trees experiencing more stress and die-off in the monitoring plot during the
drought than in the remaining portion of the buffer.

Along Stream A, the vegetation is healthy and well developed, with rushes, silky willow, and
silky dogwood shrubs growing along the channel. Where water is concentrated in pools below
drops, the shrubs and herbaceous vegetation are heavy. Where the stream channel is dryer, in
runs or riffles, the streambank vegetation is mainly herbaceous with less growth of the shrubs.
But many of the live stakes are still viable and will take off and grow strongly once normal
rainfall returns to the mountains. In our opinion, the only area of concern is around the lower
monitoring plot itself.
Stream B
Stream B has experienced difficulties in getting vegetation of any type established in the upper
section. This area was constructed with the deepest grading cuts and may have the poorest soil.
The upper section also has had no summer flow since the relocation was completed, adding
additional stress on newly planted vegetation. (Note - this was also the condition prior to the
stream relocation as the upper section of Stream B was primarily a drainageway for the seep in
the forest to the confluence of the wetland drainages). The area has been replanted with trees
and shrubs which are beginning to show signs of growth after surviving the past few years with
minimal growth. As the stem count data shows on Figure 4, there were 13 stems surviving in the
plot on this section (Upper Stream B), well over the 10 stems required for the plot size with an
additional 9 volunteer stems.

Figure 4. Vegetative monitoring plot for Stream B, upper monitoring plot, BannerLowes
Project, Banner Elk, NC, 2009.
There are volunteer species of black cherry and elderberry growing in the buffer and monitoring
plot of the upper section. The soil appropriate for native herbaceous species seems to be the
limiting factor in this area. A hardy vegetation cover like those used by NCDOT may be more
appropriate in order to stabilize the exposed banks. During field inspections with US COE and
NC DENR staff, it was concluded that any hardy cover would be approved. This cover would
provide shade, erosion control, and add a natural organic deposition to the banks, allowing for
the establishment of future native trees and shrubs.
The lower section of Stream B has more vegetation as it has a more constant source of water
from the wetland seeps. This source almost dried up during the summer months, but generally
was present for the remainder of the year. The monitoring of this vegetative plot and the buffer
shows the trees and shrubs are growing, albeit slowly, due to the previous years of drought.
They are difficult to see, especially in the summer months when the herbaceous vegetation grows
quite tall , but most of the stems are present and viable. The monitoring plot on the lower section
(Lower Stream B) is well under the success criteria as shown in Figure 5 and needs additional
plantings to meet the Year 5 success criteria goal. Other buffer areas along Stream B may need
additional stems in scattered locations on a site specific basis. The lower Stream B at the
property line has very little buffer area and has created a linear wetland in the channel, which
would be too wet for additional tree plantings. Additional stems and reseeding of appropriate
areas around Stream B will be addressed in the replanting section below.

Elk River Restoration
The Elk River comments in the DWQ letter concerned the encroachment by grounds keeping
activities into the buffer and the need for additional trees in the downstream buffer on the west
side of the river. The grounds keeping activities were impacting Stream A and are addressed
above. According to the survey overlays of the Conservation Easement boundaries, the
landscaping activities were not impacting the protected Elk River buffer adjacent to the parking
lot. Lowes management indicated that they would restrict further mowing activities into the
wettest areas at the toe of the slope next to the Elk River buffer. As noted in the wetland section
above, an emergent wetland has formed due to a spring draining through this area. Areas outside
of the wetland are extremely rocky from residue of the flood events in 2004 and lack the soil
cover for growing large trees as yet.
Addressing the trees needed along the downstream buffer of the Elk River, a survey in May 2009
showed 11 birches (yellow, cherry or river) from the original plantings surviving with one dead
birch in the area. The majority of the birches have not increased in height over the past 3 years,
remaining at 1'-2' in height and well hidden during the summer months. The trees have been
putting their energies into growing roots up to now. Herbaceous cover and shrubs have survived
in greater densities and are providing soil cover. Other trees planted in the area did not survive
the construction activities of the stream restoration or the drought conditions. Trees planted on
the berms adjacent to the stream channel had poor survival due to the rocky conditions left by the
flood events. Recent rainfall in the region has boosted the tree growth and survival, but
additional trees could be planted to assist this buffer stabilization. The replanting of this area
will be address in the replanting section.
11
Stream Conclusion
No additional morphology monitoring of Stream A, Stream B and the Elk River will be required
(Appendix Q. The main areas of concern are the vegetation survival in specific areas and the
amount of stream credits. A replanting plan for the project will be submitted to the agencies and
installed during the 2010 winter-spring months. Vegetative monitoring of the plots on Stream A
and Stream B will continue for the remaining two years. Elk River buffer replanting will be
monitored through survival of the replants and photographic documentation. Measurements and
documentation of the total amount of stream length restored will continue for the next two years
under normal rainfall events for the region.
Replanting Plan 2010
Replanting efforts of trees, live stakes, and herbaceous seeding will be conducted in the areas
noted above. Trees will be planted within the lower Stream A monitoring plot, within the lower
Stream B plot, as needed throughout the Stream B buffer and within the buffers of the Elk River
downstream of the access bridge. Live stakes will be added around the edges of Wetland 1 and 2
to supplement the herbaceous vegetation. Seeding of the upper Stream B area will be redone
with more hardy seed types that will provide cover quickly and efficiently in the primarily dry
channel and slopes adjacent to the dry channel.

Banner Elk Lowes Mitigation Credits - Final

Subject: Banner Elk Lowe's Mitigation Requirements-Final
Attachments: ActualMitigationCredit.xls
Here's what I finally came up with. Called the 0.82 creation based on how we reviewed
it/classified it in the permit. Called the 0.25 restoration which came up with a total of 0.65 acre
of credit generated which makes a deficit of 0.08 acre. Due to the quality of the wetlands being
impacted (low) and the quality of the wetlands created/restored (high), I will not require any
additional mitigation to compensate for that deficit of 0.08 acre. Please check the notes section to
make sure they correspond to the changes I made.
Also, I am permanently suspending monitoring requirements on the relocated stream channel
located directly behind the building due to its questionable jurisdiction. A good example of why
mountain headwater ephemeral/intermittent channels should not be attempted to "restored" -
lesson learned. I do strongly recommend that the area be planted in some sort of ground cover for
stabilization.
With regards to the continuation of monitoring on the remaining wetlands, I am satisfied that
these areas will remain jurisdictional wetlands in their current condition (minus any natural
events) and don't believe any additional monitoring would reveal any significant changes. I do
however, expect that the next hurricane event could deposit material in these areas and fill them
and also possibly scour out new areas (newly created wetlands). The more I've worked this area,
the more I realize how transitional some of these floodplains wetlands are and that our goal of
creating/restoring wetlands in this area for five years is short-sighted at best. The main benefit
this work has provided is that the Elk River still has a floodplain to do what it needs to do and
the stormwater entering the river has a functioning buffer (with the help of storm water
management facilities).
Unless Kevin or Eric have anything to add or objections, these are my final comments.

2008 Post-Construction Monitoring Report
Avery County
DWQ #03-1134
Dear Ms. Wiggins:
Resources
Dee Freeman
Secretary
The Division of Water Quality (DWQ) 401 Oversight and Express Review Permitting Unit has
reviewed the Monitoring Report for the above-referenced site, and have reviewed your request
for closeout of the monitoring period for the restored wetlands. In addition, Eric Kulz with this
Office conducted a site visit in the summer of 2008. Our comments on the project and
monitoring report are as follows:
Streams
The morphological data presented in the monitoring report appear to show that the streams are
stable. Both relocated streams (UTA and UTB) appeared to be low-flow streams; UTA had
water only in the lower portion of the channel, and UTB was dry during the site visit.
With respect to the vegetation, the method of presentation of the data in the report make
evaluating success of the project difficult. Tree data are normally presented with raw data
extrapolated to stems per acre for each monitoring plot. According to the interagency Stream
Mitigation Guidelines (April 2003), survival of woody species planted at mitigation sites should
be at least 320 stems per acre through year 3. It is unclear if this criteria is being met, based on
the data in the monitoring report.
However, during the site visit, vegetation appears to be a problem for the riparian zones of all the
streams. Survival and vigor appeared poor on both of the UTs, and diversity appeared low,
likely due to drought conditions. Buffer width is an issue on both UTA and the Elk River.
Encroachment by groundskeeping activities and proximity of UTA to the parking lot are
concerns.

Based on the Project History presented on Page 4 of the report, construction of the stream
restoration portions of the project was completed in October 2005. Planting was done in
December 2005, with supplemental planting events in 2006 and 2007_2008 represents the third
growing season, based on the initial planting.
With respect to the buffers at this site, the success of this mitigation project is not at all assured.
Continued poor survival, encroachment and vandalism may result in additional monitoring past
the five-year mark.
Wetlands
As noted above, the method of presentation of the tree data make comparison of data from the
site to success criteria difficult. However, due to poor woody vegetation survival and multiple
repair and replanting events during the last 3 years, we recommend that monitoring continue
until it is clear that the targeted community has become established in the restored wetlands.
In regards to vegetation monitoring, we suggest that stem counts continue for planted and
volunteer woody species. Vegetation plots should not all include live stakes, as these tend to
skew the stem counts. Denisty data should be representative of the wetland are as a whole.
Results should be presented as described above, and compared with the success criteria for
wetland mitigation (320 stems per acre in year 3, 288 stems per acre in year 4, and 260 stems per
acre in year 5). However, it is not necessary to count stems of herbaceous vegetation; estimates
of percent cover will be adequate in future monitoring reports.
Based on the Project History presented on Page 4 of the monitoring report, construction of the
wetland cells was completed in May 2006, and planting was completed in June 2006. Therefore,
the first full growing season for the wetlands was 2007. 2008 only represents the second
growing season for the wetland portion of the site.
Wetland mitigation projects generally require monitoring for five years or until success criteria
are met, whichever is longer.
DWQ would be happy to meet on the site with USACE personnel to discuss the progress of the
stream and wetland mitigation, but.we feel that monitoring of this site should, at a minimum,
continue through the five growing seasons outlined in applicable mitigation guidance.

Hi Barbara:
This has been discussed by both Central Office and Regional Office.
based on 401 water quality certification, this project (with the abandonment of the relocated
stream channel, and that the channel may have had its groundwater hydrology removed from the
shifting of the channel) has a stream mitigation deficit. We need to come up with credits to
resolve the Certification requirements.
The DWQ has no issue with the wetland mitigation accounting.

Kevin

Hi Barbara:
had quick exchange with central office staff and this is the general consensus:
• Elk River and Stream A are stable, and no additional geomorphic monitoring is required.
• Stream A should be replanted, and veg monitoring continue.
• Wetland hydrology and wetland veg should continue for time being.
• Stream B is unresolved. Issues is it is in 404 and 401 application as needing mitigation, and we
have no sucessful mitigation to get it off books (so to say). I will follow up with this.
Thanks,
Kevin

Subject: BannerLowe current monitoring status
Kevin and Amanda -
Based on both COE and DWQ comments over the past few months, we have the following
monitoring requirements left at BannerLowes project - please let us know if this is not correct.
All morphological surveys are no longer needed - Stream A, Stream B and Elk River; this
includes cross sections, long pro, pebble counts and BEHI.
DWQ has asked for hydrology monitoring in the wetlands continue while COE has indicated no
further monitoring will be needed. There will be a gap in crest and stream height data in spring
2009 due to this discrepancy in agency requirements. This data will be provided to both
agencies for the year to date.
Vegetation monitoring needs to continue and additional plantings need to be added. We will do
the monitoring plots as usual, but with Eric Kulz's request to drop the livestakes. All buffer areas
will be evaluated this week to document the growth after a normal year of rain.. We expect the
numbers and survival to be up considerably from past years.
Stream B is a perennial stream downstream of the wetland confluence and will be confirmed
with a stream identification rating. The upstream section will be evaluated for intermittent rating
this week and the results submitted to both agencies. If needed, a recheck of this section 48
hours after a rain event will be performed to document flowing conditions. We will also be
surveying and measuring any additional stream channel lengths in the wetland area behind
Lowes' store.
Photographs of the overall project areas will be made.
Please let me know if there are any additional monitoring requirements that need to be
performed. Thanks.

Hi Barbara:
After a quick review of the previous a-mails between this office, Central office, and yourself, it is my
understanding that the low producing well was thrown out as being not representative, and the
remainder of the wells had met the mitigation criteria.
At this time, we have no issue with Fish and Wildlife Associates removing these wells for use at the
Muse - Peddlers Square project.

PROJECT SITE
The BannerLowe Mitigation Project is located in Avery County, NC in the Town of Banner
Elk. The project is located south of Banner Elk on the west side of NC 184 (Tynecastle Road),
in the mountain ecoregion of North Carolina (Figure 1). The property at BannerLowes is
composed of a total of 29.3 acres bordering Tynecastle Road. Tynecastle Road is the major
thoroughfare into the Town of Banner Elk and the primary commercial corridor. This property
has 720 feet of road frontage on Tynecastle Road. Primary access to the tract is through the
Lowes access drive from Tynecastle Road. Secondary access is over a private road (Glove
Factory Lane) adjacent to the old Glove Factory land (south) and a private road (Stonebridge
Lane) adjacent to a Car Wash (north). Land use in the project vicinity is commercial along
Tynecastle Road with residential homes set back from the road. The property was used for a
residential home, barn and agricultural pasture prior to construction of the commercial
buildings.
The project is located within the Elk River watershed of the Watauga River Basin. The site lies
in US Geological Survey (USGS) Cataloging Unit 06010103 and North Carolina Division of
Water Quality (NCDWQ) sub-basin 04-02-01 of the Watauga River Basin. The mitigation
project involves three streams and two wetlands on the property. There are two unnamed
tributaries (UTA & UTB), with UTA flowing into the Elk River on the southeast side of the
property. UTB flows into the Elk river at a point downstream of the property. The Elk River
borders the property on the east side. The drainage areas involved include the Elk River at 2.95
square miles, the UTA at 0.04 square miles, and the UTB at 0.1 square miles.
The Elk River flows parallel to Tynecastle Road and bisects the property. The Elk River was
approximately six feet wide and six inches deep with a cobble, gravel, and sand substrate. The
river experiences impacts from beaver activity and floods (March 2003 and September 2004).
These impacts had resulted in bank and channel degradation of the Elk River on the property.
Preconstruction conditions can be seen in the photographs in Appendix A.

For the restoration project, the lower portion of the Elk River (3871f) was stabilized and the
profile and dimension restored in the stretch (Figure 2). UTA was relocated to the south side of
the property and restored for a length of 5361f. Another UT joins with UTA near the head of
the stream, but is not included in the mitigation project. UTA is a perennial stream and was
channelized prior to the project. See photographs of the stream before the project was
constructed in Appendix A. UTB had been channelized and all riparian vegetation removed
during the agricultural use of the property. UTB was an intermittent stream upstream of the
property and became a perennial stream downstream at the confluence with two tributaries
draining the springs west of the property. UTB was relocated and restored to a length of 1,089
If UTB had been channelized through the pasture, flowing northward into an old pond bed
(Appendix A).
The restoration project included two wetlands located adjacent to the Elk River on the east side
of the river. The project to date has restored Wetland #1 (upstream above the bridge) between
the stormwater wetland BMP and the Elk River. It was restored to 0.30 acres in size. The
project has restored 0.34 acres of Wetland #2 (downstream of the bridge). Further wetlands
have become established on the west side of the Elk River due to natural groundwater flow.
The design for the BannerLowe project involved the restoration of channel dimension, pattern,
and profile on the Elk River and two of its unnamed tributaries (UTA and UTB). After
construction was complete, 2,012 feet of stream had been restored on the site and 0.64 acres of
wetland. This Annual Report details the results of the monitoring efforts performed during
2008 (Year 3 Morphological Surveys) at the BannerLowe Site.

METHODS
Longitudinal and cross section reference sites were photographed immediately after construction
and will be documented for at least five years following construction. Photographs will be taken
at each of the vegetation plots during each growing season for at least five years following
construction. Two (2) permanent cross-sections will be installed per 1,000 linear feet of stream
restoration work, with one (1) located at a riffle cross-section and one (1) located at a pool cross-
section. There were two cross sections installed on each restored stream segment. A
longitudinal profile will be completed once during the first year after construction and then every
two years (for a total of three times over the five year monitoring period). Measurements will
include thalweg, water surface, inner berm, bankfull, and top of low bank.
Bank erosion measurements will be made at each permanent cross section. A bank erodibility
hazard index (BEHI) score will also be made at each cross section. Pebble counts will be
conducted at each permanent cross section (100 counts per cross section) and reach-wide over
twenty bankfull widths (100 counts total). Pebble counts will be conducted one year after
construction and at a two-year interval thereafter at the time the longitudinal field surveys are
performed.
Vegetative monitoring plots were established on each of the stream restoration stretches. There
were two 25'x 50' plots each established on UTA, UTB and the Elk River. Trees and shrubs are
flagged and counted each year and survival will be determined based on initial plantings. Within
these monitoring plots, herbaceous vegetation will be monitored using a one meter plot for
determining density and diversity of herbaceous vegetation. Live stakes are monitored with one
plot 50' long on both sides of the streams adjacent to the vegetative monitoring plots, with all
live stakes counted and tracked to determine survival.
Wetlands will be monitored for success using hydrology determinations through groundwater
wells, crest gage, stream gage and rainfall data, wetland rating scores, vegetative stem counts,
herbaceous density and diversity, hydrophytic vegetation, and photographs of the two wetland
areas through the monitoring period. These conditions will be monitored for five years or until
success criteria have been met.
RESULTS - Listed Chronologically from Pre Construction
Pre-Construction Conditions 2004
Pre-construction observations in April 2004 of the streams UTA and UTB showed impacts from
the agricultural use of the land surrounding the two streams. Photographs of the pre-construction
conditions can be found in Appendix A. UTA had very little buffer and was not protected from
livestock access. UTB had some areas of natural vegetation and buffer, especially near the
wetland areas on the west side of the project. Most of UTB was heavily impacted from clearing
and livestock access, with drastic changes in pattern and dimension as can be seen in the
photographs in Appendix A. The Elk River through the project had areas of bank erosion,
dimension impacts from beaver dams, and clearing of the buffer through most of the length
within the project boundaries.
The wetlands on the project had been impacted historically through fill and livestock access to
the area. All of the valley wetlands and the Elk River were heavily impacted through three
consecutive floods in September 2004. The Elk River shifted its channel to the west and much
of the wetlands closest to the river were filled with sand and rock debris from the floods. The
Elk River was relocated back into its original channel in October to prevent the channel erosion
and sediment load from cutting anew channel. The wetland areas adjacent to the river were
heavily impacted from sand and rock deposits and were greatly reduced in size and function.
Photographs of these conditions can be seen in Appendix A. Restoration of the wetlands and the
connection with the Elk River through the mitigation plan would restore these wetland areas.

Plans showing as built conditions and photographs for the three streams and the two wetlands are
included in Appendix B. The active project construction extended over a long period of time
with more than a year in construction and planting activities for the project. As can be seen on
the timetable of the project history, the stream restoration projects were completed at two
different times in 2005. The wetlands were not completed until May of 2006. Vegetation
planting efforts were spread out throughout and are continuing into 2007, due to seasonal
planting requirements. There were multiple impacts to the streams and wetlands from adjacent
construction activities, including stormwater BMP construction, sediment and erosion control
structures, utility installations, and general construction impacts. Vandalism had been noted in
2005 and is still being observed through current field surveys. All of these impacts on the
projects will be discussed as it impacted the individual monitoring components and how the
impacts were repaired. Lowes opened for business in early July 2006, ending most landscaping
and associated construction activities.
No excessive rainfall events or floods occurred during 2005 or 2006. Rain events are
documented under the Wetland Restoration monitoring for the site. There were high stream
level events but no bankfull events in 2005 or 2006 as recorded by the crest gage. More
discussion of the precipitation and stream levels will be covered under the stream longitudinal
profile and the wetland restoration sections of this report.
Vegetation Monitoring
STREAMS
Plantings on the three streams began as early as July 2005 and were still continuing into 2007.
There was a partial livestake planting on UTA and UTB in July 2005 along with native grass
seeding to provide an initial head start for bank stabilization. Elk River was planted with native
seeds and livestakes in October of 2005. All three streams were planted with trees in December
2005 and with the rest of the livestakes in March/April of 2006. Some areas on the streams and
the Elk River could not be planted, due to continuing site construction, sediment control fencing,
and other limiting factors. In December 2005, a sewer line crossing disturbed a portion of UTB
and a construction vehicle became stuck in UTA, requiring repairs on both those streams.
Several trees that had been planted along along the streams and river were observed run over,
pushed over or pulled up. Construction on utility lines had impacted all plantings near the lower
section of UTB on the west side.
UTA had lost all of its tree plantings on the south side of the stream in the area from the berm to
the side unnamed tributary, probably due to the ATV that was observed in May 2006 using the
area as a driving track. The area was posted with signs and replanted in the summer of 2006.
Initial vegetation plantings were surveyed during July 2006 for live stakes, tree plantings and
herbaceous cover in the monitoring plots.
WETLANDS
The restored wetlands were completed in May 2006 and seeds and livestakes were planted where
final construction grade was in place. The wetland areas immediately showed signs of
hydrology, hydric soil development and immediate establishment of hydrophytic vegetation with
good growth. The area along the Elk River on both wetlands could not be planted due to
construction activities and Wetland #1 was limited in planting on the stormwater wetland side
until after June 2006. The joint monitoring plots for Wetland #2 and the Elk River were
established and initial stem counts were made.
RESULTS
Vegetative monitoring plot data for the streams and wetlands showed some of the above impacts
during the July survey, but not all of the impacts. None of the plots have been through a full
growing season except for the live stakes on UTA and UTB. Only six monitoring plots out of
eleven were up to design planting numbers in 2006. The other five plots were still under impacts
from construction activities. The number of tree and shrub stems per acre ranged from 67 to 633
stems/acre. Livestake plots ranged from 1200 to 1633 stems/acre on the streams. The wetlands
monitoring plots were only partially planted in 2006 and ranged from no livestakes in one plot to
600 stems/acre in the second plot. Herbaceous plots were established on all streams and wetlands
in 2006 and will be surveyed in 2007 after a full year of unimpacted growth. Preliminary
surveys show that the herbaceous plots are experiencing good growth and cover in the meter
plot. New plantings and replantings of trees, shrubs and livestakes are planned for the winter of
2006-2007 to insure the initial counts met design criteria and will be reported in the 2007
monitoring report.
Longitudinal Profile and Cross Section
The total length of stream channel restored on the three streams on the site was 2012 feet. This
entire length was inspected during Year 1 of the monitoring period (2006) to assess stream
performance. Two cross sections and one longitudinal profile on each stream were surveyed and
plotted in October 2006. The longitudinal profile is shown in Appendix C. A third cross section
on Stream B (Cross Section #1, Station 1219) was located in the intermittent flow section and
has had no flows except for rain runoff. This cross section will be dropped and the remaining
two cross sections will be used for the two permanent cross section monitoring points. Based on
the data collected, all riffles, pools, and other constructed features along the restored channel are
stable and functioning as designed. The lack of significant problem areas along the length of the
restored channel after the occurrence of at least one river flow larger than bankfull discharge
further supports functionality of the design. It is expected that stability and in-stream habitat of
the system will only improve in the coming years as permanent vegetation becomes more
established.
7
Bank Erosion estimates and BEHI
Bank erosion estimates were not performed in 2006, but the cross section surveys show no
change from the as-built conditions. Erosion pins will be installed in 2007 and monitored for the
remainder of the monitoring period.
BEHI observations for UTA were low to very low as the vegetation is very well established, the
channel is connected to its floodplain, and the slope is low. There is one area of higher BEHI
where the second UT confluence enters UTA. UTB has more disturbed channel where the flood
event in late summer of 2005 washed out all channel vegetation down to rock and bedrock, but
the stream banks were recovering and were well covered with vegetation. UTB BEHI ranges
from Low to Moderate with some areas showing a High rating. The Elk River has vegetation
growing along its stream banks, but has been slow to completely cover the banks as the majority
of the bank materials were large cobble and even some boulders. This helps to maintain the
stability of the stream banks even without the vegetation growth. The Elk River BEHI ranges
from Very Low to Moderate, depending on the amount of rocks present in the bank.
Pebble Count
Pebble counts at each permanent cross section and reach-wide over twenty bankfull widths were
performed on the three restored streams and the data is shown in Appendix C. Pebble counts for
the Elk River show a very coarse gravel substrate for the river. UTA and UTB have a medium
gravel substrate. UTB is receiving some sediment from the upstream channel construction which
has not had any water flow other than rain runoff since construction began on the site. The
intermittent channel has become ephemeral until the confluence with the wetland channels.
Downstream of the wetland flow the UTB is perennial.
Wetland Restoration
Two wetland areas adjacent to the Elk River on the east side were restored. This construction
was completed in May-June 2006 and the wetlands have not experienced a full year after
construction yet. Preliminary groundwater data, stream height, and crest levels from August
2006 to February 2007 are shown in Appendix C. Initial data indicates that when the stream
levels rise, the groundwater gages in the two wetlands also respond with a rise in water level.
Soil observations indicate that hydric soils are already developing in both wetland areas. Hydric
vegetation has covered both wetlands except in the deeper water areas. The Wetland #1 has
experienced ponding on the lower end and adjustments are being made to lower the standing
water level. Final adjustments will be made during the growing season of 2007 in order to
maintain hydrology of the wetland. All indications show that the two restored wetlands are
functioning as effective wetlands and maintaining the hydrology, vegetation and hydric soil
conditions of a riparian wetland connected to the adjacent Elk River.

Wetland Restoration
In 2007, most areas of the stream and wetland restoration project were stable and returning to
natural conditions. Two areas of exception were the stormwater wetland berm shared with the
upper wetland (Wetland #1) and the buffer between Stream A and Lowes parking lot. The
stormwater wetland required some construction repairs and a change in discharge pattern into
Wetland #1 which disturbed the berm. This area was replanted with herbaceous seeds and plants
after the grading was completed. The buffer along Stream A next to the Lowes parking lot
continued to be impacted by mowing activities. This area was remarked, reflagged, and
replanted in the fall of 2007. Collett and Associates notified Lowes again of the required buffer
rules. Replanting efforts continued around the restored wetlands during the appropriate season
for plantings.
During 2007 the region was experiencing extreme drought conditions, especially by late summer
and fall. Stream B was dry until just below the discharge outfall from the stormwater BMP, and
less than 40% of the new stream channel had flow by October 2007. Stream A had no to very
minimal flow and vegetation was growing into the stream channel. No excessive rainfall events
or floods occurred during 2007. Rain events are documented under the Wetland Restoration
monitoring for the site. There were high stream level events but no bankfull events in 2005 -
2007 as recorded by the crest gauge. More discussion of the precipitation and stream levels will
be covered under the wetland restoration sections of this report.
Vegetation Monitoring
Streams
Plantings on the three streams began as early as July 2005 and are still continuing into 2008. As
noted above, the buffer along Stream A has continued to experience impacts from mowing and
was replanted again in the Fall of 2007, after the vegetation monitoring had been performed for
the year.
Wetlands
In 2007 the first full growing season had been encountered for the restored wetlands. The
wetland areas continue to show signs of hydrology, hydric soil development and establishment of
hydrophytic vegetation with good growth. This was despite regional drought conditions in
Western NC, indicating successful restoration of wetlands will be possible at this site.
Additional live stake and tree plantings on the berm between the restored wetlands and the Elk
River were not completed before the monitoring occurred in 2007, due to seasonal requirements.
Vegetation Results
Vegetative monitoring plot data for the streams and wetlands showed some areas of improved
growth and success in 2007 and other areas which are still below the required number of stems.
The tables of the results can be seen in Appendix D. Stream A upper monitoring plot next to the
Lowe's parking lot was still being impacted by mowing in the buffer. More trees and shrubs will
be planted in the fall of 2007 and the area was marked with high visibility stakes and paint. The
live stakes along the stream channel are showing good survival, despite the dry stream channel.
The Stream A lower monitoring plot needs additional replanting to bring the area back up in
stem numbers, but the ones that survived the vandalism and ATV impacts are doing well.
Stream B survival in the lower monitoring plot is in good condition, with good live stake
survival and stem survival. The upper monitoring plot on Stream B needs more density of stems,
but those that were planted are surviving. A replanting of trees and shrubs will be done during
the winter months of 2007-2008 to bring the density in the buffer back to the original planting
density.
The two wetland monitoring plots are doing well with herbaceous vegetation, but the live stakes
showed poor survival (conditions were too wet where they were planted). The wetlands are
scheduled for replanting at higher elevations on the slopes with trees and live stakes. This will
occur during the winter months of 2007-2008. In Wetland #2, the upper monitoring plot live
stake area is showing good survival and density. All wetland monitoring plots will be primarily
herbaceous cover due to the degree of moisture present and will be primarily a marsh-type
wetland versus a hardwood or bottomland wetland.
Herbaceous monitoring plots with one exception are showing 80-100% cover. Stem counts
ranged from 17,000-56,000 on most meter plots with the exception of the upper Stream B
monitoring plot. This reach of Stream B has been slow to grow plants of any type, despite
several reseeding attempts and fertilizer additions. More seeding and soil testing will be
performed during the winter months to ensure good growth by the growing season of 2008.
Longitudinal Profile and Cross Section
This was Monitoring Year 2, so no longitudinal profile surveys or pebble counts were performed.
Two cross sections on each stream were surveyed and plotted in October 2007. There are some
changes shown on the cross section comparison graphs. Much of the buffer changes from 2006
to 2007 were due to additional land grading after the streams were constructed and surveyed.
Changes in the dimension in Stream A and Stream B from As-Built conditions were due to one
large rain event in the late summer of 2005 which scoured out the vegetation and the channel in
the two smaller streams. Based on the data collected, all riffles, pools, and other constructed
features along the restored channels are stable and functioning as designed. There are small
areas of unstable or eroding stream bank due to the slow growth of vegetation as noted in the
vegetation section of this report, primarily along Stream B. The data from the crest gauge
indicates that several high water events have occurred since completion of the stream restoration
and that the design is functioning as proposed. It is expected that stability and in-stream habitat
of the system will only improve in the coming years as permanent vegetation becomes more
established.
10
Bank Erosion estimates and BEHI
BEHI observations for UTA were Very Low as the vegetation is very well established, the
channel is connected to its floodplain, and the slope is low. There is one area of less stable banks
where the second UT confluence enters UTA. UTB has more disturbed channel where the flood
event in late 2005 washed out all channel vegetation down to rock and bedrock, but the stream
banks were recovering and were well covered with vegetation in the lower section. UTB BEHI
ranges from Very Low to Low with some of the dry upstream areas showing a Moderate to High
rating. The Elk River has vegetation growing along its stream banks and has stabilized well,
despite the dry weather conditions. The Elk River BEHI ranges from Very Low to Low,
depending on the bank height and bank angle.
Erosion pins were installed in 2007 and will be monitored for the remainder of the monitoring
period.
Wetland Restoration
Two wetland areas adjacent to the Elk River on the east side were restored with the design of a
backwater depression and a levee next to the Elk River. This is the first full year after
construction was completed in June 2006. Groundwater data, stream height, crest levels, and
rainfall amounts from August 2006 to January 2008 are shown in Appendix D. Two of the
gauges lost memory during the period February to June 2007. These two gauges were in
separate wetlands, so there was at least one gauge functioning during this period in each wetland.
Gauges GW2 and GW3 were in Wetland #1 on the upstream side of the access bridge and
showed saturated conditions during the growing season. GW2 was in hydrology that had
standing water on the surface during part of the monitoring period and within 2" of the surface
the remaining time. GW3 generally showed hydrology present within 5' to 10" of the surface for
the whole period graphed. Steps were taken to reduce the ponding of the water in Wetland #1
with future adjustments possible if standing water remains too high, even in the dryer seasons.
In Wetland #2 on the downstream side of the access bridge, GW 1 and GW4 fluctuated between
5" and 20" in water level below the surface throughout the period, with generally higher water
levels in the winter and lower in the dryer summer months. Variation in the elevation was
present during the summer and fall months which were related to the rain events in the valley.
The Restored Wetlands meet the success criteria of hydrology of inundation or saturation within
12 inches of the soil surface for a minimum of 8-20 consecutive days of the growing season
beginning May 1 and ending October 11 for the 2006 and 2007 growing seasons.
Hydric soil conditions were documented in both restored wetlands. Wetland #1 had a soil
classification of 7.5 YR 4/1 in the top 12" with mottles of 7.5 YR 4/6 in sandy loam soil. The
soil was saturated throughout and inundated in some locations within the wetland. Wetland #2
had soils with lOYR 3/1 in 0'-2", 2.5Y 3/1 from 2"-8", and 2.5 Y 7/2 in 8" - 18" with mottles
throughout in a clayey loam soil. The water table was noted at 12" in both wetlands in August
2007.
11
Vegetation success has been achieved with 100% herbaceous cover in the restored wetlands with
almost 100% hydrophytic vegetation present within the boundaries of the two Wetlands. The
wetlands' species are comparable to reference marsh-type wetlands common in the Elk River
watershed. Stem counts for trees and shrubs on the berms and levee have not been as successful,
due to the delay in planting and as shown on the vegetative result table. Additional plantings and
stakings will be made to insure the success criteria of 328 stems/acres are achieved for the
wetland berm areas.
Overbank flow was monitored with the crest gauge. No data shows that the river crested over
the levee on the upstream site where the gauge was located. However, the levee in the
downstream reach of Wetland #2 was built slightly lower and seemed to experience a bankfull
event when the crest gauge showed elevated water levels below but close to bankfull. There may
have been two events over the period graphed where bankfull was achieved on the lower
wetland. Another factor involved in the hydration of the wetlands was the consistency of the
levees and general soil in the buffer adjacent to the Elk River -a mixture of soil and large cobble
and boulders from historic and current flood events. The cobble mixture allows water flow
between the wetlands and the Elk River during less than bankfull events. This can be observed
through the comparison of the water levels of the groundwater wells and the river water levels
over the period monitored. Peaks in the river water levels can be observed at the same time as
elevation peaks in the groundwater wells, indicating a connection between the water levels of
both the wetlands and the river.
Measurement of the wetland area showed 0.29 acres in Wetland #1 and 0.29 acres in Wetland #2
for a total of 0.58, a slight decrease from the 0.64 acres measured in 2007. This minor decrease
was during a period of drought and showed stable restored wetlands on the project site.
Especially in Wetland #1, the wetland is expanding towards the adjacent commercial property
due to spring heads on the south side. Expansion towards the stormwater wetland BMP is also
expected now that construction and repair activities have been completed.

Wetland Restoration
In 2008 the area in western North Carolina experienced the second to third year of drought
conditions, with the area under extreme drought during certain periods of time. The project areas
of the stream and wetland restoration project were stable and returning to natural conditions.
The stormwater wetland berm has become vegetated after the repair work of 2007 and the native
vegetation was becoming established. This growth around and in the stormwater wetland was
slowed by the dry conditions, but the vegetation is present, albeit very small. The buffer along
Stream A next to the Lowes parking lot continued to be impacted by mowing activities. Despite
the communication with Lowes, mowing continued within the buffer area on the north side of
Stream A. Collett and Associates have discussed the situation with Lowes management. A
proposal for replanting 3-5 year old trees and a fence installed is being prepared for Lowes.
12
During 2008 the region was experiencing extreme drought conditions for the second full year,
especially by late summer and fall. Stream B was dry until just below the discharge from the
wetland areas and less than 50% of the new stream channel had now by August 2008. Stream A
had little to no flow and vegetation (primarily rushes) were growing in the stream channel. Rain
events are documented under the Wetland Restoration monitoring for the site. There were high
stream level events in 2008 and at least one bankfull event in late August 2008. More discussion
of the precipitation and stream levels will be covered under the wetland restoration sections of
this report.
Vegetation Monitoring
stream s,
Plantings on the three streams began as early as July 2005 and were completed in the spring of
2008. As noted above, the buffer along Stream A has continued to experience impacts from
mowing and was replanted again in the spring of 2008. The new trees were impacted by mowing
during 2008 prior to the monitoring in August 2008.
Wetlands
In 2008 the restored wetlands had experienced the second full growing season. The wetland
areas continued to show signs of hydrology, hydric soil development and establishment of
hydrophytic vegetation with good growth as can be seen in the Photos in Appendix E. This was
despite regional drought conditions in Western NC as noted previously.
Vegetation Results
Vegetative monitoring plot data for the streams and wetlands showed some areas of improved
growth and success in 2008 and other areas which are still below the required number of stems.
The tables of the results can be seen in Appendix E. Replanting of trees and shrubs occurred in
the spring of 2008 and are noted in the tables as replanted within the monitoring plots.
Replanting of the plots will be done to raise the number of stems to meet the success criteria.
Some of the replanted trees did not survive during the drought conditions of 2008. Some
changes in species identification over the years have occurred as the specimens have grown large
enough for definitive identification, particularly the birch species.
Stream A plot counts showed the impact of the drought conditions in the region. The lower
Stream A vegetation monitoring plot was replanted with additional stems, but was still under the
Year 3 Success Criteria. Two of the stems replanted earlier this year did not survive for the
August plant survey. Stream A upper monitoring plot exceeded the success criteria for the MY3,
primarily due to the replanting efforts. Stream A buffer next to the Lowe's parking lot was still
being impacted by mowing. The live stakes along the stream channel were showing good
survival of silky willows, despite the dry stream channel. The rest of the buffer area around
Stream A was well covered with native vegetation on the south side. The north side was grass
lawn with occasional tree stems. This mowed buffer area will be addressed through additional
13
replanting of older (3-5 year old) trees and installation of a fence during the coming year by
Lowes management.
Stream B survival in the lower monitoring plot was still short on stem survival, also due to the
drought conditions. The live stake plot was showing good survival and growth, primarily of
silky willows. The upper monitoring plot on Stream B showed good volunteer growth of
additional black cherry trees and elderberry shrubs. The total stem count met the success criteria
for the plot for MY3.
The restored wetland monitoring plots were doing well with herbaceous, hydrophytic vegetation
well established. Both restored wetland areas are recovering as marsh-type wetland, with
herbaceous species as the predominate vegetation. Both plots in Wetland #1 are meeting the
stem success criteria for Year 3. Most of the stems are shrubs, due to the wetland conditions, but
river birch and black willow are also present in one of the plots. Tree survival will be limited to
the edges of the plots due to the hydrology in the wetland. Wetland #2 vegetation monitoring
plots are well above the Year 3 success criteria. Silky willows were the predominant species that
are surviving due to the wet conditions. Red maple and black cherry trees were also found on
the slopes above the wetland. The majority of vegetation in Wetland #2 monitoring plots was
rushes and other herbaceous wetland species. The Elk River/Wetland #2 live stake area is
showing good survival and density of silky willow, willow sp., and silky dogwood.
Herbaceous monitoring plots with one exception are showing 80-100% cover as shown in the
photographs in Appendix D. Stem counts ranged from 11,000- 49,000 on all meter plots with
the exception of the upper Stream B monitoring plot (Table 2). This reach of Stream B has been
slow to grow plants of any type, despite several reseeding attempts and fertilizer additions. The
drought conditions have made it difficult for herbaceous plants to become established. There is
progress in vegetative cover occurring in this reach, however, and with return to normal rainfall
amounts should be well established by the end of the monitoring period.

Longitudinal Profile and Cross Section
A longitudinal profile and two cross sections on each stream were surveyed and plotted in
August 2008. The longitudinal profile was surveyed in 2005 (As-Built), 2006 and 2008 and the
results shown in Figures 2-5. The Elk River profile showed only minor changes from the As-
Built condition. In areas where depth had increased in 2006, deposition refilled to As-Built
condition or above in 2008. No headcutting was observed and the structures are holding the
profile as designed. Some accumulation of bed material was occurring in the riffles.

Stream A showed a stable profile over the three year period. No headcutting or major changes in
the profile can be seen in Figure 3. There was some adjustment of the stream channel with
increased slopes and less pools after the drop/pool structures. Most the stream was covered with
vegetation and the channel was being encroached by vegetation during the low flow conditions
of 2008. This allowed for more deposition of fine sediments and the creation of more runs and
riffles with less pools. The profile was considered in a stable condition for an intermittent
stream.
Stream B profiles are shown in Figures 4 and 5. The upper stations (Figure 4) were dry during
the monitoring survey in 2008. This portion of the stream had shown intermittent stream
characteristics previously and did not pick up perennial flows in the summer until below the
wetland on the west side of the project. The upper profile had shown some areas of adjustment,
but overall was maintaining the design profile elevation. One reach near Station 125-175 will be
watched for bed erosion continuing in that area.

The lower profile stations (Figure 5) from Station 500.0 - Station 1100.0 had enough water flow
during the summer months to allow for the growth of wetland plants, particularly at the lower
end where a solid stand of rushes was established in 2008. The profile showed adjustment at
some stations, but overall maintained the As-Built profile elevations. Areas of deposition and
erosion were observed on the profile, but the structures were holding nickpoints in place.
Longitudinal profiles will be surveyed in 2010 during monitoring year 5 for any further changes
or signs of unstable conditions.

The cross section surveys performed this year showed similar stability as the profiles. There are
some changes shown on the cross section comparison graphs shown in Figures 6-11. Much of
the changes from As-Built conditions were due to additional land grading along the buffer after
the streams were constructed and surveyed. On the Elk River, the cross section surveys show the
structures and features along the restored channels are stable and functioning as designed
(Figures 6-7). Vegetation is well established at both Elk River Cross Section Stations, providing
additional bank stabilization.

For Stream A, the riffle dimension shows no changes, but the pool dimension shows shifting of
sides and shape (Figures 8-9). This was observed to be a stable channel as shown in the
photographs in Appendix E and from observations of the channel and stream bank throughout
Stream A. The changes observed were due to the stream adjusting and shifting to a stable
dimension. Most of the Stream A channel was 100% covered by canopy and many places had
vegetation growing within the channel, due to the lack of flow in the stream.

Stream B cross section at Station 1209 has continued to widen, but has maintained the same
depth over the years (Figure 10). The widening of the cross section is due to limited vegetation
20
on the upper stations on Stream B. The vegetation was more stressed in the upper reach due to
the drought conditions. There are small areas of unstable or eroding stream bank due to the slow
growth of vegetation as noted in the vegetation section of this report, in the upper reaches of
Stream B. The pool at Station 1634 showed little change over the last 4 years (Figure 11).
The data from the crest gauge indicates that several high water events have occurred since
completion of the stream restoration and that the design is functioning as designed. As noted in
previous reports, it is expected that stability and in-stream habitat of the system will only
improve in the coming years as the stream channels stabilize into a final pattern, dimension and
profile. All streams will be assisted when the buffer vegetation becomes established.
Photographs of each stream profile and cross section are included in the Appendix E of this
report.

Bank Erosion estimates and BEHI
No major changes in BEHI on the three streams were seen over the past 3 years. BEHI
observations for UTA were Very Low to Low as the vegetation is very well established, the
channel is connected to its floodplain, and the slope is low. There is one area of less stable banks
where the second UT confluence enters UTA. UTB BEHI ranges from Very Low to Low with
some of the dry upstream areas showing a Moderate rating. The upstream UTB BEHI will
improve further as the vegetation growth improves. The Elk River has vegetation growing along
its stream banks and has remained stabilized, despite the dry weather conditions. The Elk River
BEHI ranges from Very Low to Low, depending on the bank height and bank angle.

22
No changes in erosion pin measurements were observed except for slight changes due to the
extensive vegetative growth that has provided increased deposition of organic material over the
pins.
Pebble Count
Pebble counts at each permanent cross section were performed on the three restored streams and
the data is shown in Appendix E. Pebble counts for the Elk River showed a shift from a very
coarse gravel substrate in 2006 to a finer gravel and sandy substrate in 2008. UTA has shifted
from a medium gravel substrate to a silty substrate. UTA flow was reduced greatly in 2008 and
the channel was invaded by rooted vegetation, contributing to the shift in substrate. This was a
natural shift due to flow reduction and was not an indication of channel instability. UTB also
shifted from a medium gravel substrate to a predominately silty substrate. UTB, like UTA, was
experiencing intermittent flow regimes during 2007 and 2008. The upper intermittent channel
on UTB had become ephemeral until the confluence with the wetland channels.
Wetland Restoration
Two wetland areas continued to be restored as wetlands. Groundwater data, stream height, crest
levels, and rainfall amounts from January 2008 to December 2008 are shown in Appendix E.
The restored wetlands were evaluated as to whether they met the success criteria of hydrology of
inundation or saturation within 12 inches of the soil surface for a minimum of 8-20 consecutive
days of the growing season beginning May 1 and ending October 11 for the 2008 growing
season.
Gauges GW2 and GW3 in Wetland #1 showed saturated or surface water conditions throughout
the growing season in 2008 as shown on the graphs in Appendix E. Wetland #1 received an
increase in hydrology source with the new discharge outlet from the stormwater wetland BMP
into the southern end of the wetland. GW 1 in Wetland #2 showed saturated conditions during
the growing season for well over 20 consecutive days in June-July 2008. GW4 did not show
saturated conditions for 8 consecutive days in 2008. Saturation at 12" depth at GW4 occurred
intermittently during rain events in June and July, but due to the drought conditions in the region,
were not sustained. GW4 lost a source of hydrology when the stormwater wetland BMP outlet
was realigned to discharge into the upper restored wetland. The old discharge alignment resulted
in much of the stormwater wetland flow to pass through the culvert in the road berm to the lower
Wetland #2. Despite this decrease in hydrology, overall Wetland #2 retained wetland
characteristics of hydrology, hydric soil and hydrophytic vegetation. Unless the drought
continues, this area should remain as a restored wetland in the future.
Hydric soil conditions were documented in both restored wetlands. Wetland #1 had a soil
classification of 7.5 YR 2.5/1 in the top 12" with mottles of 7.5 YR 5/8 in sandy clay loam soil.
The soil was saturated throughout and inundated in some locations within the wetland. The
water table was noted above the soil surface (0.5"). Wetland #2 had soils with 10YR 3/2 in the
0"- 4" horizon, with mottles of 7.5 5/8 with a sandy clay loam soil. The soils were 10YR 4/1
23
from 4"-12". At 12", stream gravel and cobble were encountered in higher proportions. The
water table was noted at above the soil surface (0.5").
Vegetation success has been achieved with 100% herbaceous cover in the restored wetlands with
almost 100% hydrophytic vegetation present within the boundaries of the two Wetlands. The
wetlands' species are comparable to reference marsh-type wetlands common in the Elk River
watershed. Species found prevalent in both wetlands are Juncus effusus, carex sp., Salix sericea,
and Mimulus ringens. Many other wetland species were present in community pockets in and
around the wetlands.
Overbank flow from the Elk River to the wetlands was monitored with the crest gauge. At one
date the crest gage was at or close to top of bank. Five other dates in 2008 the crest gage showed
the stream level within 4" of top of bank. When the crest gage elevated points are compared
with the groundwater wells within the wetlands, there is a match between the elevated crest gage
readings and some of the groundwater well levels. The consistency of the levees and general soil
in the buffer adjacent to the Elk River -a mixture of soil and large cobble and boulders from
historic and current flood events- allows water flow between the wetlands and the Elk River
during less than bankfull events. Similarly, peaks in the river water levels in the stream gage
graph (Appendix E) can be observed at the same time as elevation peaks in the groundwater
wells, indicating a connection between the water levels of both the wetlands and the river.
Measurement of the wetland areas in 2008 showed 0.29 acres in Wetland #1 (down from 0.30 ac
in 2007) and 0.29 acres in Wetland #2 (down from 0.32 ac in 2007) restored so far for a total of
0.58 acres restored. This compares with 0.64 acres restored in 2007. Considering the extent of
the drought conditions in the region, this was a minor decrease and showed that the wetlands will
maintain hydrology during dry conditions. Expansion towards the stormwater wetland BMP has
balanced some of the loss of wetland in Wetland #1.
FUTURE SAMPLING
Annual sampling will be performed at the BannerLowes Project site in 2009 and 2010 or until
the success benchmarks are achieved.
