I. Executive Summary / Project Abstract
The Gray Farm Stream Restoration project consists of two separate reaches (Reach 1 and
Reach 2) along unnamed tributaries of Buffalo Shoals Creek, a tributary of the Catawba
River (Hydrologic Cataloging Unit 03050101). The site is located approximately 10
' miles due west of the City of Statesville in western Iredell County, NC. This restoration
was contracted by Restoration Systems LLC (Contract # D05016-2) as a full-delivery
project for the North Carolina Ecosystem Enhancement Program (NCEEP). This report
' summarizes the monitoring efforts for Year 2 (2007) of the Gray Farm Stream
Restoration Project.
' Restoration construction of the Reach 2 began in early March 2006 and was completed in
mid-April 2006. Restoration construction of the Reach I began in mid-April 2006 and
was completed in early July 2006. Demobilization and minor Contractor punch list items
' were completed shortly thereafter. Installation of monitoring devices and As-built
surveys for both reaches were performed as construction progressed.
Monitoring of the vegetated buffer was performed during the growing season of 2007 by
Soil & Environmental Consultants, PA (S&EC). Stem counts were performed within the
established vegetation monitoring plots, resulting in an average live stem density of
' approximately 452 stems per acre.
Physical monitoring of the restored channel consisted of the collection of cross-section
and representative longitudinal profile data, and a visual assessment of the stream.
Collected data was then compared with As-built and Year 1 Monitoring data.

II. Project Background
The Gray Farm Stream Restoration project is located in the Catawba Basin, Hydrologic
Cataloging Unit 03050101. The site consists of two separate reaches (Reach 1 and Reach
2) along unnamed tributaries of Buffalo Shoals Creek, a tributary of the Catawba River.
The site is located approximately 10 miles due west of the City of Statesville in western
Iredell County, NC.
The restoration project objective was to restore the impaired streams to appropriately
sized stream channels that were stable and self-maintaining, and would not aggrade or
degrade over time. Restoration was accomplished with Rosgen-based natural channel
design procedures and techniques. Reach 1 restoration was a combination of a Priority I
(reconnection of the channel with its historic floodplain) restoration and a Priority II
(construction of a new floodplain at a lower elevation) restoration. Reach 2 was a
Priority I restoration. Restoring an appropriate sinuosity lengthened both channels,
thereby lowering their bankfull slope.
Restoration construction of the Reach 2 began in early March 2006 and was completed in
mid-April 2006. Restoration construction of the Reach 1 began in mid-April 2006 and
was completed in early July 2006. The buffer of both reaches of the restored stream
channel were planted with native tree and shrub species and seeded with a native grass
seed mix. During construction, site topography and grading allowed for the creation of
vernal pools, oxbows, or pocket wetlands within the riparian zone along the restored
reaches. Planting operations were performed in April 2006. Supplemental planting was
performed in December of 2006.
Demobilization and minor Contractor punch list items were completed shortly after the
completion of construction. Installation of monitoring devices and As-built surveys for
both reaches were performed as construction progressed.
1. Project Goals and Objectives
The goals of the Gray Farm Stream Restoration project are:
1) Improve local water quality within the restored channel reaches as well as
the downstream watercourses through;
a. The reduction of current channel and off site sediment loads by
restoring appropriately sized channels with stable beds and
banks.
b. The reduction of nutrient loads (both soil enhancement practices
and cattle) from adjacent agricultural fields with a restored
riparian buffer.
Gray Farm Stream Restoration Site Soil & Environmental Consultants, PA
Year 2 Monitoring 2 S&EC Job # 9385.D8
December 2007 Restoration Systems Contract # D05016-2
' c. The reduction of water temperatures provided by shading of the
channel from canopy species along with the resultant increase in
oxygen content.
' 2) Improve local aquatic and terrestrial habitat and diversity within the
restored channels and their vicinity through;
' a. The formation of varying bed form within the channels to
provide for fish, amphibian, and benthic species.
' b. The restoration of a suitable riparian buffer corridor which will
provide both vertical and horizontal structure and connectivity
with adjacent upland areas.
c. The restoration of understory and canopy species which will
provide forage, cover, and nesting for a variety of mammals,
reptiles, and avian species.
3) Improve local watershed conditions through the restoration of two low
order streams (one first order, one second order) and the placement of
permanent conservation easements.
' Through the restoration process the following objectives were accomplished:

n
1) Restore approximately 7,610 linear feet of appropriately sized stream
channel that is stable and self-maintaining, and will not aggrade or
degrade over time. Restoration was accomplished with Rosgen-based
natural channel design procedures and techniques.
2) Develop restored channels with the appropriate morphological
characteristics (cross-sectional dimension, pattern, and longitudinal
profile) utilizing collected reference reach data as a guide. Allow for no
net loss of overall channel length in the process.
3) Create and/or improve bed form diversity (riffles, runs, pools, and glides)
and improve aquatic and benthic macroinvertebrate habitat.
4) Construct a floodplain (or local bankfull bench) that is accessible at the
proposed bankfull channel elevation.
5) Ensure channel and stream bank stabilization by integrating in-stream
structures and native bank vegetation.
6) Establish a native forested and herbaceous riverine buffer plant
community within a minimum width of 50 feet from the edge of the
restored channel. This new community will be established in conjunction
with the eradication of any existing exotic and/or undesirable plant
species.

7) Improve water quality within the subject channels and the downstream
receiving waters.
8) Supplement the education and conservation efforts for natural resources in
Iredell County as indicated in program goals for the local Soil & Water
Conservation District and the NC Cooperative Extension Service.
2. Project Structure, Restoration Type, and Approach
The restoration project objective was to restore the impaired streams to appropriately
sized stream channels that are stable and self-maintaining, and will not aggrade or
degrade over time. Restoration was accomplished with Rosgen-based natural channel
design procedures and techniques. Restoring an appropriate sinuosity lengthened
both channels, thereby lowering their bankfull slope. A total of 8,004 linear feet of
stream channel were restored onsite (8,004 SMU's).
Reach 1
Reach 1 restoration was a combination of a Priority I (reconnection of the channel
with its historic floodplain) restoration and a Priority II (construction of a new
floodplain at a lower elevation) restoration. Approximately 800 linear feet of this
length was previously inundated by an existing farm pond that was removed
during the channel restoration. The pre-restoration length of this channel segment
was approximately 4,340 linear feet.
One additional piped farm road crossing existed approximately 700 feet
downstream of the dam. This piped crossing was removed and replaced with an
in-stream crossing. Immediately downstream of the dam for a distance of
approximately 1,000 feet, severe bank erosion, channel incision, and an over-
widening of the stream channel was evidenced. This degradation appeared in
large part due to previous uncontrolled releases from the existing dam spillway.
The lower two thirds of the reach were characterized by overly steep and undercut
banks. Significant localized erosion was evidenced along this lower portion.
Trees of large diameter lined the banks, many of which were undercut, suspended
or had collapsed into the stream. The channel had down cut and over widened in
many locations along the reach allowing no access to its floodplain. The last 200
feet (approximately) of the pre-existing channel was not down cut due to a change
in surrounding topography.
The upper portion of Reach 1 has demonstrated pool development since the as-
built survey. Significant sediment entered the pools at the upper end of Reach 1
shortly after construction. This sediment came from upstream sources including
areas of cattle pasture and areas previously inundated due to the old pond. This
sediment has been flushed from the system during the first year causing these
pools to deepen to their previously excavated depth.

December 2007 Restoration Systems Contract # D05016-2
Reach 1 consists of 5,813 (5,813 SMU's) linear feet of restored Type C4 channel.
Reach 2
Reach 2 was a Priority I restoration. A small impoundment previously existed
near the lower end of the reach; however, it was drained and removed a number of
' years prior to the channel restoration. A piped farm road crossing existed at
roughly the same location (the old dam embankment). This was (and remains) the
only existing crossing along the reach. The pre-restoration length of this channel
' segment was approximately 1,600 linear feet.
Throughout Reach 2, severe bank erosion, channel incision, and an over-widening
' of the stream channel were evidenced. This impairment appeared in large part
due to previous uncontrolled grazing operations. The reach was characterized by
overly steep, sloughing, and undercut banks.
Significant localized erosion was evidenced along the entire reach. Trees of large
diameter lined the banks, many of which were undercut, suspended or collapsed
' into the stream. The channel had down cut and over widened in many places
along the reach allowing no access to its floodplain.
Reach 2 consists of 2,191 linear feet (2,191 SMU's) of restored Type B4 channel.
3. Location and Setting
The Gray Farm Stream Restoration project is located in the Catawba Basin,
Hydrologic Cataloging Unit 03050101. The site consists of two separate reaches
(Reach 1 and Reach 2) along unnamed tributaries of Buffalo Shoals Creek, a tributary
of the Catawba River. The site is located approximately 10 miles due west of the
City of Statesville in western Iredell County, NC.
Reach 1 is located immediately north of Bolick Road (SR 1532). Reach 2 is located
immediately west of the intersection of New Sterling Road (SR 1525) and Gray
House Road. The watershed areas for Reaches 1 and 2 are estimated at
approximately 0.91 square miles (582 acres) and 0.085 square miles (54 acres)
respectively. See attached Figure 1.

5. Monitoring Plan View
Six (6) tree and shrub buffer vegetation plots (four (4) on Reach 1 and two (2) on
Reach 2) and four (4) bank vegetation plots (two (2) on Reach 1 and two (2) on
Reach 2) were established. All monitoring will occur within these observation plots
throughout the monitoring period for as long as they continue to be representative of
the community.
For all buffer monitoring plots, Level 1 of the Carolina Vegetation Survey-Ecosystem
Enhancement Program (CVS-EEP) Protocol for Recording Vegetation will be utilized
for vegetation sampling in Years 1 and 2. Subsequent monitoring years will utilize
Level 2 of the CVS-EEP protocol in order to record and report woody plant
volunteers within vegetation monitoring plots along with planted stems. A corner of
each vegetation monitoring plot will be used as a permanent photo point for
vegetation monitoring photos. Locations of these photo points are shown on the
attached Monitoring Plan View.
A total of seven (7) nested riffle and pool cross-section pairs were established along
Reach 1, and two (2) nested riffle and pool cross-section pairs were established along
Reach 2. Each cross-section also serves as a designated photo point that will be
photographed annually.
The locations of all monitoring devices are shown on Sheets 2 through 6 (Reach 1-
Monitoring Plan View) and Sheets 11 through 14 (Reach 2 - Monitoring Plan View).
III. Project Condition and Monitoring Results
A. Vegetation Assessment
The success of the adjacent riparian buffer will be based on the combined
survival of tree and shrub species for the five-year monitoring period.
Survival of woody (tree and shrub) species planted within the restored buffers
will be at least 320 stems/acre through year three, 288 stems/acre through year
four, 260 stems/acre through year five. The stem count will be based on an
average of the stem counts of the evaluated tree and shrub buffer vegetation
plots.
The success of the bank vegetation plots along the restored channels will be
based on the survival of live-stake (or other) bank plantings for the five-year
monitoring period. Survival of bank plantings will be based on a linear
average of approximately 50 percent of the planted species within the
restoration reaches.
Biological monitoring will be used as a general indicator of restoration
success, however, no specific biological criteria applies to the success of the
restoration reaches.

' The approximately 18.4 acre restoration area was planted with various native
hardwood tree and shrub species, native to the area. Reaches 1 and 2 were
' planted in April 2006. Supplemental planting was performed in December of
2006.
' The following tree species were planted in the Riparian Buffer Area:
• Alnus serrulata (Tag Alder)
' • Betula nigra (River Birch)
• Carpinus caroliniana (Ironwood)
• Fraxinus pennsylvanica (Green Ash)
' • Ilex opaca (American Holly)
• Lindera benzoin (Spicebush)
• Liriodendron tulipifera (Tulip Poplar)
' • Platanus occidentalis (Sycamore)
• Quercus michauxii (Swamp Chestnut Oak)
' • Quercus nigra (Water Oak)
• Quercus phellos (Willow Oak)
• Viburnum nudum (Possumhaw)
' Stream banks were planted with live stakes in two offset rows. The following
shrub species were planted as live stakes:
' • Cornus amomum (Silky Dogwood)
• Salix sericea (Silky Willow)
• Sambucus canadensis (Elderberry)

1
As previously described, a total of six (6) buffer vegetation monitoring plots
were established on site in 2006. The success criteria for the site require a
minimum of 320 live stems per acre for the first three (3) years of monitoring.
Year 2 vegetation monitoring shows 452 live stems per acre. Future buffer
vegetation monitoring data will be compared with previous monitoring data to
determine survival rates and stem densities for woody vegetation planted
within the riparian buffer. Vegetation monitoring data for buffer plots was
collected using the CVS-EEP monitoring protocol and is presented in
Appendix A.
Four (4) bank vegetation plots were also established (two on each reach) to
monitor survival of live-stake plantings along stream banks. Future bank
vegetation monitoring data will be compared with previous monitoring data to
determine survival rates for live-stakes planted along stream banks. Live
stake survival from Monitoring Year 1 to Monitoring Year 2 for the site
overall is approximately 68.9%. Live-stake counts by species and by plot are
presented in the following tables:

Live-stake mortality can be attributed to drought conditions during the 2007
growing season as well as dense herbaceous vegetation along stream banks.
Most surviving live stakes appear to be healthy and growing vigorously.
Herbaceous vegetation varies widely throughout the restoration site. The
native herbaceous species have become densely established and are dominant
throughout the site. Herbaceous species observed along stream banks and in
the buffer and wetlands onsite include:
• Impatiens capensis - Jewelweed
• Juncus effusus - Soft Rush
• Leersia oryzoides - Cutgrass
• Mimulus ringens - Monkeyflower

' The dense herbaceous vegetation at the lower end of Reach 2 combined with
the steep slope and drought conditions have severely stressed planted tree
species and caused their slow establishment. This area will be monitored
' closely and, if necessary, recommendations will be made for management or
supplemental planting.
' The lower section of Reach 1 and the upper section of Reach 2 are dominated
by sparse, low growing cover crop grasses. In these areas the planted woody
species have lower mortality, appear healthier, and have grown more in the
' last year compared with the areas of extremely dense herbaceous vegetation.
In areas given shade by surrounding mature trees, planted woody species are
healthy and thriving likely due to less intense light and heat during drought
conditions and a less dense herbaceous layer (See Buffer Plots 3 & 4-Reach
1).
1. Problem Areas Plan View (Vegetation)
During a field inspection on November 27 & 28, 2007, a total of twelve
' localized areas of bare banks and floodplain were observed on Reaches 1 and
2. These areas appear to be due primarily to either surface flows or poor soil
conditions. Drought conditions during the growing season have likely
' contributed as well. These areas are shown on Sheets 6 through 9 (Reach 1)
and Sheets 14 through 16 (Reach 2). Photos are included in Appendix A.
' Some small amounts of the non-natives johnsongrass (Sorghum halepense)
and tall fescue (Lolium arundinaceum) have been observed at the edges of the
' buffer restoration areas that border the agricultural fields on both reaches.
These populations will be closely monitored to ensure they do not become
dominant or exclude native vegetation.
' An area of kudzu (Pueraria lobata) was noted at the site in early June, 2007,
on the west side of Reach 1 between stations 16+00 to 19+00. Although the
' majority of the kudzu was along and in the edge of the woods immediately
outside the easement area, some had encroached into the easement area. The
area (approximately 0.5 acre) was treated with the herbicide Transline
' (clopyralid) at a rate of one pint per acre. The area will continue to be
monitored to determine if re-treatment is necessary.
While we will continue to monitor these areas, based on vegetative success
criteria the site currently exhibits strong vegetative success.
' 2. Vegetative Problem Areas Plan View
Vegetative problem areas are shown on Sheets 6 through 9 for Reach 1 and

B. Stream Assessment
A review of available on-line USGS gauge sites was performed to determine
if a suitable surrogate gauges was present in the area. No nearby gauge was
identified. The closest USGS gauge to the site was on the Lower Little River
(near Healing Springs, NC, Gauge Identification Number 02142000) which is
approximately 15 miles from the project site.
Based on this large distance, significant disparity in watershed sizes, and
topographic variation, it is unlikely that a conclusive determination regarding
the number of bankfull events experienced on the restoration site could be
made.
However, based on site observations, to include wrack lines, floatsom,
staining of vegetation, displaced/flattened vegetation, and observable
sediment deposition, it is apparent that multiple overbank events have
occurred during this monitoring year.

An assessment of channel stability was also preformed on November 27 &28,
2007, by S&EC. Areas of concern that were observed and documented
included some minor localized bank scour and four stressed structures. Detail
of such scour is evidenced in cross-section 6 (pool). These problem areas are
shown on Sheets 6 through 9 for Reach 1 and Sheets 14 through 16 for Reach
2 (Problem Area Plan View).
And, while we will continue to monitor these areas, based on physical success
criteria the site clearly exhibits stable conditions and meets the requirements
for physical success.

A visual qualitative assessment was performed to inspect channel facets,
meanders, bed, banks, and installed structures. This visual assessment was
confirmed and enhanced with a quantitative assessment of the physical stream
survey. The goal of this assessment is to provide a percentage of the features
listed in Table VII that are in a state of stability. Table VII was compiled
from the data in Table B I in Appendix B of this report.

6. Quantitative Measures Summary Tables
The following tables (Table VIII and Table IX) summarize the quantitative
data collected from the cross-sectional and representative longitudinal stream
survey. This data was analyzed and summarized, and then compared with
baseline data types available for this project.
The Quantitative Morphology Tables illustrate the degree of departure, if any,
of the current channel from the baseline data. Tables VIII and IX were
compiled from the cross-section and profile raw data and plots located in
Appendix B of this report.
