1.0 Executive Summary
The Lyle Creek Mitigation Site, hereafter referred to as the Site, is a full - delivery stream and
wetland restoration project for the North Carolina Ecosystem Enhancement Program ( NCEEP)
in Catawba County, NC The Site is located west of NC Highway so/ North Main Street in the
Town of Catawba, NC (Figure 1) The project is located in the Catawba River Basin Hydrologic
Unit Code (HUC) 030503.01140oso, and North Carolina Division of Water Quality (NCDWQ)
Subbasin 03- 08 -32, which is within a NCEEP Targeted Local Watershed This HUC qualifies as
a service area for an adjacent HUC, therefore, the Lyle Creek Mitigation Site was submitted for
Mitigation credit in the Catawba River Basin HUC 03050103
The Site is 18 miles east of Hickory, 15 miles southwest of Statesville and approximately z
miles south of I -4o The Site is located on an active tree farm surrounded by woods and
residential land use The Site is bounded by Lyle Creek to the north, NC Highway so/ North
Main Street to the east and an elevated railroad right -of -way to the south The Site is located
on one parcel owned by the Garmon Family A Conservation Easement held by the State of
North Carolina has been recorded with the Catawba County Register of Deeds on the 26 6z-
acre Lyle Creek project study area within the Garmon parcel The conservation easement
allows the restoration work to occur and protects the project area In perpetuity Signage and
demarcation were placed along the easement per current NCEEP guidance
Lyle Creek flows into the Catawba River less than a mile downstream of the proposed
mitigation site The NCDWQ assigns best usage classifications to State Waters that reflect
water quality conditions and potential resource usage Lyle Creek (NCDWQ Index No 11 -76-
4 5) Is the main receiving tributary of the project reaches and has been classified as Class WS-
IV, CA waters Class WS -IV waters are used as sources of water supply for drinking or food
processing purposes where a more restrictive WS -I, WS -II, or WS -III classification is not
feasible These waters are also protected for Class C uses such as secondary recreation,
fishing, wildlife, fish and aquatic life propagation and survival and agriculture WS -IV waters
are generally in moderately to highly- developed watersheds or Protected Areas This portion
of Lyle Creek is also located within the Critical Area (CA) of the Catawba River/ Lake Norman
Directions and a map of the Site are provided in Figure 1
z s Project Goals and Objectives
Prior to construction activities, the onsite UTs to Lyle Creek were regularly modified and
maintained and therefore lacked bedform diversity, habitat, and riparian buffer The primary
impacts to the project channels were the result of mowing, ditching, vegetation maintenance,
and dredging associated with tree farming activities As a result of the aforementioned land
activities, the onsite streams were Incised and overly wide with shallow flow These stream
conditions resulted In many of the onsite streams being unable to maintain channel form and
subsequently filled In with sediment, organic matter and vegetation In- stream bedform
diversity was extremely poor and the longitudinal profile was dominated by shallow runs The
lack of bedform diversity combined with continued anthropogenlc disturbance resulted In
degraded aquatic habitat, altered hydrology (related to loss of floodplaln connection and

lowered water table) and water quality concerns such as lower dissolved oxygen levels (due to
shallow flow with few re- aeration points) Tables 1-4 in Appendix 1 present the pre - restoration
conditions in detail for the Site
The primary objectives of the project were to provide ecological and water quality
enhancements to the Catawba River Basin while creating a functional riparian corridor at the
site level, providing wetland habitat and ecological function, and restoring a Piedmont
Bottomland Forest as described by Schafale and Weakley (199o) These objectives were
achieved by restoring 5,411 linear feet (LF) of perennial and intermittent stream channel and
6 6 acres (ac) of wetland area, enhancing 1,384 LF of intermittent stream channel and creating
z 9 ac of wetland area Approximately 179 LF of stream was excluded from the total project
credit calculations from crossings (farm roads and power line easements) The Site's riparian
areas were also planted to stabilize streambanks and wetland areas, improve habitat, and
protect water quality The ecological uplift can be summarized as starting from tree farming -
impacted streams and wetlands and moving to stable channels and wetlands in a protected
riparian corridor Restoration of dimension, pattern, and profile was implemented for UTs,
UTsa, and UTsb, enhancement of profile and dimension was implemented for UTsc and UTsd
Wetland restoration and creation included RWs and RW2 UTsa and UTsb discharge into an
anastomosed wetland complex upstream of their confluence with UTs as depicted in Figure z
This anastomosed wetland complex was not proposed for stream mitigation credit Figure z
and Table 1 present the implemented design for the Site
Monitored enhancements to water quality and ecological processes established in the
mitigation plan are outlined below, followed by expected project benefits which are associated
with restoration, but will not be monitored as part of this project
Monitored Project Goals
• Wetland areas will be disked to increase surface roughness and better capture
rainfall which will improve connection with the water table for groundwater recharge
Adjacent streams will be stabilized and established with a floodplain elevation to
promote hydrologic transfer between wetland and stream
• A channel with riffle -pool sequences and some rock and wood structures will be created
in the steeper project reaches and a channel with run -pool sequences and woody debris
structures will be created in the low sloped project reaches for macroinvertebrate and
fish habitat Introduction of wood including root wads and woody 'riffles' along with
native stream bank vegetation will substantially increase habitat value Gravel areas
will be added as appropriate to further diversify available habitats
• Adjacent buffer areas will be restored by removing invasive vegetation and planting
native vegetation These areas will be allowed to receive more regular and inundating
flows Riparian wetland areas will be restored and enhanced to provide wetland
habitat
• Sediment input from eroding stream banks will be reduced by installing bioengineering
and in- stream structures while creating a stable channel form using geomorphic design
principles
Lyle Creek Mitigation Site Page z
Monitoring Year i Annual Report —FINAL

T
Expected Project Benefits
• Chemical fertilizer and pesticide levels will be decreased by filtering runoff from
adjacent tree farm operations through restored native buffer zones and wetlands
Offsite nutrient input will be absorbed onsite by filtering flood flows through restored
floodplain areas and wetlands, where flood flows can disperse through native
vegetation and be captured in vernal pools Increased surface water residency time will
provide contact treatment time and groundwater recharge potential
• Sediment from offsite sources will be captured during bankfull or greater flows by
deposition on restored floodplain areas where native vegetation will slow overland flow
velocities
• Restored riffle /step -pool sequences on the upper reach of UTsa, where distinct points
of re- aeration can occur, will allow for oxygen levels to be maintained in the perennial
reaches Small log steps on the upstream portion of UTsb and UT-1 Reach 1 Upper will
also provide re- aeration points
• Creation of deep pool zones will lower temperature, helping to maintain dissolved
oxygen concentrations Pools will form below drops on the steeper project reaches and
around areas of woody debris on the low- sloped project reaches Establishment and
maintenance of riparian buffers will create long -term shading of the channel flow to
minimize thermal heating
The stream restoration success criteria for the Site follows the approved performance criteria
presented in the NCEEP Mitigation Plan Template (version 1 0, 11/20/2009) and the Stream
Mitigation Guidelines issued in April 2003 by the USACE and NCDWQ Annual monitoring and
quarterly site visits will be conducted to assess the condition of the finished project for five
years, or until success criteria are met The stream restoration reaches (UTs, UTsa, and UTsb)
of the project were assigned specific performance criteria components for stream morphology,
hydrology, and vegetation The enhancement reaches (UTsc and UTsd) were documented
through photographs and visual assessments to verify that no significant degradational
changes are occurring in the stream channel or riparian corridor Monitoring for wetland
vegetation will extend seven years beyond completion of construction The wetland
restoration and creation sections have been assigned specific performance criteria for
hydrology and vegetation
12 Monitoring Year 1 Data Assessment
The final mitigation plan was submitted and accepted by the NCEEP in August 2011
Construction activities were completed by River Works, Inc in April 2012 The baseline
monitoring (Year o of 5) and as -built survey were conducted in April and May 2012 The first
annual monitoring assessment (Year 1 of 5) was completed in October 2012 The Site will be
monitored for a total of seven (7) years, the stream and vegetation assessment will be
monitored for five (5) years and the wetland assessment will be monitored for seven (7) years
The final monitoring activities will be conducted in 2018 and the close -out in 2019 Monitoring
consists of collecting morphological, vegetative, and hydrological data on an annual basis to
assess the project success based on the restoration goals and objectives The success of the
Site will be assessed using measurements of the stream channel's dimension, pattern, and

profile, permanent photographs, stream and wetland vegetation, and groundwater and
surface water hydrology Any areas with identified high priority problems, such as stream
bank instability, aggradation /degradation, lack of vegetation establishment, or failure to meet
groundwater hydrology success criteria, will be evaluated on a case -by -case basis The
problem areas will be visually noted and remedial actions will be discussed with NCEEP staff to
determine a plan of action
1 2 1 Vegetative Assessment
A total of 35 vegetation monitoring plots were installed and evaluated within the
restoration, enhancement, and creation areas to measure the survival of the planted trees
The number of monitoring quadrants required is based on the NCEEP monitoring guidance
documents (version 2 0, 10/14/1o) The size of individual quadrants is loo square meters for
woody tree species and shrubs Vegetation assessments were conducted following the
Carolina Vegetation Survey (CVS) Level 2 Protocol for Recording Vegetation (Lee et al ,
2oo8)
The initial baseline survey was conducted within 21 days from completion of site planting
and will be used for subsequent monitoring year comparisons The plot corners were
marked and are recoverable either through field identification or with the use of a GPS unit
Reference photographs at the origin looking diagonally across the plot to the opposite
corner were taken to capture the same reference photograph locations as the as -built The
final vegetative success criteria will be the survival of 26o planted stems per acre in the
riparian corridor along restored and enhanced reaches at the end of year five (5) of the
monitoring period The interim measure of vegetative success for the Site will be the
survival of at least 320 planted stems per acre at the end of year three (3) of the monitoring
period
The monitoring year 1 (MY -1) vegetative survey was completed in September 2012 The
2012 annual vegetation monitoring resulted in an average survivability of 372 stems per
acre, which is greater than the interim requirement of 320 stems /acre, but approximately
30% less than the baseline density recorded (S31 stems /acre) in April 2012 There was an
average of g stems per plot compared to 13 stems per plot in MY -o A total of 26 out of 35
plots were on track to meet the success criteria required for MY -3 (Table 7, Appendix 3) A
vegetative maintenance plan is presented below to address the low stem density observed
during MY -1 Please refer to Appendix 3 for vegetation summary tables and raw data
tables and Appendix 2 for vegetation plot photographs and the vegetation condition
assessment table
Maintenance Plan
The Site will be re- planted in late winter 2012 in response to the quantity of dead bare roots
observed during the 2012 vegetative survey Most likely, the high mortality of the planted
stems was a result of dry soil conditions, low precipitation, and /or from grass suffocation or
crowding of planted stems To promote better success, the planting list will be modified
slightly to account for species that were not successful in the initial planting The small

areas where invasive species have been noted will continue to be monitored and treated on
a regular basis
1 z z Stream Assessment
In order to monitor the channel dimension, a total of 12 permanent cross - sections have
been installed along the UTs to Lyle Creek, 8 on UT1, 2 on UT1a, and z on UT1b Cross -
sections are located at representative riffle /run and pool sections on each monitored reach
Each cross - section is permanently marked with pins to establish its location Cross - section
surveys will be performed annually and will include points measured at all breaks in slope,
including top of bank, bankfull, edge of water, and thalweg
A longitudinal profile was completed for 4,46o LF of the restoration reaches (3,000 LF on
UT1, 615 LF on UT1a and 845 LF on UT1b) on the Site immediately post - construction and
will be repeated annually throughout the five year monitoring period The initial as -built
survey will be used for baseline comparisons Measurements in the survey will include
thalweg, water surface, bankfull, and top of low bank These profile measurements will be
taken at the head of each riffle, run, pool, and glide, as well as at the maximum pool depth
The survey will be tied to a permanent benchmark and NC State Plane coordinates
A total of 34 permanent photographs were established within the project stream and
wetland areas after construction Photographs will be taken once a year to visually
document stability for five years following construction Permanent markers were
established so that the same locations and view directions on the site are monitored each
year Photographs will be used to monitor restoration, enhancement, and creation stream
and wetland areas as well as vegetation plots The photographer will make every effort to
maintain the same area in each photo over time Reference photos were also taken for
each of the vegetation plots and cross - sections The representative digital photo(s) will be
taken on the same day the surveys are conducted
Because the streams through the project site are dominated by sand and silt -size particles,
pebble count and /or bulk sampling procedures would not show a significant change in bed
material size or distribution over the monitoring period, therefore, bed material analyses
will not be conducted for this project
Bankfull events will be documented using a crest gage, photographs, and visual
assessments such as debris lines Three crest gages were installed, one on UT1, one on
UT1a, and one on UT1b The crest gages were installed in a permanent riffle cross - section
of the restored channels The gages will be checked at each site visit to determine if a
bankfull event has occurred Photographs will be used to document the occurrence of
debris lines and sediment deposition
Lyle Creek Mitigation Site Page 5
Monitoring Year i Annual Report—FINAL

Visual assessments will be conducted along all reaches each year to obtain qualitative
geomorphic data Each visual assessment evaluation after the baseline survey will include
re- evaluation along the same profile
Morphological surveys for the MY -1 were conducted in October 2012 All streams within
the Site met the success criteria for MY -1 Please refer to Appendix z for the visual
assessment table, current condition plan view (CCPV), and photographs and Appendix 4 for
morphological data and plots
In general cross - sections show little to no change in the bankfull area, maximum depth
ratio, or width -to -depth ratio However due to the sand /silt nature of the substrate
throughout the project, fluctuations in bed elevations are expected These fluctuations
should be temporary and likely correspond to storm events Surveyed riffle cross - sections
fell within the parameters defined for channels of the appropriate Rosgen stream type
Cross - sections g and io along UT-1A experienced sedimentation from the contributing
offsite watershed The sedimentation has not impacted channel stability These cross -
sections will be monitored with the expectation that the channel will reestablish dimension
and stable channel form
The surveyed longitudinal profile data for the stream restoration reaches illustrates that
the bedform features are maintaining lateral and vertical stability The riffles are remaining
steeper and shallower than the pools, while the pools are remaining deeper than the riffles
and maintaining flat water surface slopes The longitudinal profiles show that the bank
height ratios remain very near to 1 o for the restoration reaches Aggradation was
documented in the upper extent of UT1A The adjustments in profile are the result of
observed sediment input from the contributing watershed In- stream structures, such as
brush mattresses and sod mats used to enhance channel habitat and stability on the
outside bank of meander bends are providing stability and habitat as designed Pattern
data will be collected in MY -5 only if there are indicators from the profile or dimensions
that significant geomorphic adjustments have occurred No changes were observed during
MY -1 that indicated a change in the radius of curvature or channel belt width
At the end of the five (5) year monitoring period, two (z) or more bankfull events must
occur in separate years within the restoration reach Bankfull events were recorded across
the site (UTs, UT1A, and UT1B) with crest gages during the MY -1 data gathering Please
refer to Appendix 5 for hydrologic data
1 z 3 Wetland Assessment
Groundwater monitoring gages were established throughout the wetland restoration and
creation areas The gages were installed at appropriate locations so that the data collected
will provide an indication of groundwater levels throughout the wetland project area A
total of 8 groundwater gages were installed within the wetland areas, 5 in RWs and 3 in
RWz Historical growing season data wasn't available for Catawba County therefore the
growing season currently used for success criteria was applied from nearby Iredell County
Lyle Creek Mitigation Site
Monitoring Year iAnnual Report —FINAL

growing season data This growing season runs from April 7th to October 28th (203 days)
However, additional growing season data is being collected by two soil temperature
loggers that were installed one within each wetland These probes will be used to better
define the growing season using the threshold soil temperature of 41 degrees or higher
measured at a depth of 12 inches (USACE, 2010) in subsequent monitoring years The
probes indicate a longer growing season than that adapted from Iredell County A
barrotroll logger and a rain gage were also installed onsite All monitoring gages were
downloaded on a quarterly basis and will be maintained on an as needed basis Monitoring
gage locations are depicted on the CCPV maps in Appendix 2
The success criteria for wetland hydrology is to have a free groundwater surface within 12
inches of the ground surface for 7 percent of the growing season, which is measured on
consecutive days under typical precipitation conditions Since being installed in late March
2012 an onsite rainfall gage has recorded 13 38 inches of precipitation through mid -
November This is significantly lower than the historic annual precipitation average of
44 76 inches collected by nearby weather station Catawba 3 NNW, NC1579 (USDA, 2002)
3 of 8 gages met the annual wetland hydrology success criteria The inconsistent range of
wetland hydrology success across the site is likely due to drier than normal weather
Please refer to Appendix 5 for wetland hydrology data and plots Two additional
groundwater gages have recently been installed to provided better coverage in the
wetlands areas The locations of these gages will be included in future reports
13 Monitoring Year 1 Summary
All streams within the Site are stable and functioning as designed Aggradation observed on
UT1A will be monitored for indications of long term instability but over time the channel is
expected to transport the additional sediment The average stem density for the entire Site is
on track to meeting the overall success criteria, however, a portion of the individual vegetation
plots did not meet the MY -3 success criteria as seen in the CCPV A vegetation maintenance
plan has been proposed and will be implemented in late winter 2012 There has been one (1)
bankfull event recorded along each restored project reach since construction commenced,
therefore, the MY -5 stream hydrology attainment requirement has been partially met for the
Site at this time Currently 3 of 8 groundwater gages are meeting the success criteria for
wetland hydrology This is likely due to below normal precipitation It is anticipated that
success criteria will be met using a growing season interval defined by the onsite soil
temperature loggers during years of typical rainfall

elements can be found in the tables and figures in the report appendices Narrative
background and supporting information formerly found in these reports can be found in the
