I. EXECUTIVE SUMMARY
The Lewis Creek Stream Restoration Site (Site) is located in Henderson County, North Carolina,
northeast of the City of Hendersonville. The Site is located within the French Broad River
Watershed (USGS HUC 06010105). A Vicinity Map is included in Appendix A. The land use is
dominated by agriculture (primarily fruit orchards and row crops) and forest. Much of the
surrounding forested land is being converted to orchards and sod farms. New residential
development is also encroaching on the Site. The project area consists of approximately 1,750
linear feet of stream restoration on the main channel of Lewis Creek. The Site begins at North
Ridge Road culvert crossing and continues downstream for 1,7501f to the end of the project.
Approximately 10 acres of forested wetlands are located along the south side of Lewis Creek.
This area is owned by the Carolina Mountain Land Conservancy (CMLC). CMLC is actively
involved in the management of this site and we are coordinating closely with them during the
monitoring field work. Prior to restoration activities Lewis Creek had been impacted by
straightening and berm construction as well as being affected by upstream apple orchards. The
design was done by Jordan, Jones & Goulding, Inc. (JJG) and constructed by Carolina
Environmental Contracting for the North Carolina Ecosystem Enhancement Program (EEP). The
third year monitoring field work was done in October 2013 by Mogensen Mitigation, Inc.
(MMI). The monitoring was done in conformance with the NCEEP Monitoring Report
Template_ Version 1.5 adopted 8 June 2012 and monitoring requirements issued by the NCIRT
in November 7, 2011 and is found at:
http: // portal. ncdenr. org /c /documentclibrary/get_ file ?p_ 1_id= 1169848 &fbIderld = 2288101 &nam
e= DLFE- 39234.pdf.
The Site was constructed in April 2011 and MY -01 was done in 2012 by JJG. MY -02 was not
done and MMI is performing MY -03 in fall of 2013. The Site includes 1,750 if of stream
restoration and an unknown amount of riparian wetlands on the Lewis Creek floodplain. At the
end of the monitoring program MMI will delineate the resultant wetlands and map the extent
using GPS survey equipment. The wetlands will be delineated using the USACE 1987 Wetland
Delineation Manual.
PROJECT GOALS & OBJECTIVES
The Lewis Creek Site is located in an active agricultural community and many of the forest lands
in the area are being converted to orchards or turned to residential development. The Lewis
Creek Site is protected in perpetuity and is located immediately adjacent to a preserved mountain
bog. It is being actively managed by the CMLC. Lewis Creek is a third order tributary to Clear
Creek in the French Broad Watershed. The segment of Lewis Creek that underwent active
restoration is classified by the North Carolina Department of Environment and Natural

Resources (NCDENR) Division of Water Resources (DWR) as Class C, trout waters
(NCDDWR, 2007). The following is a list of Goals & Objectives to be gained from this project:
Goals
1. Reestablishing stream stability and capacity to transport watershed flows and
sediment load by restoring 1,750 linear feet of stable channel morphology;
2. Re- introduce a more frequent hydrologic connection between the stream and the
floodplain;
3. Establish native riparian bottomland hardwood tree and shrub community;
4. Reduce nonpoint source sediment pollution and excessive nutrient inputs;
5. Enhance the flood storage capacity of the Site by adjusting channel and/or flood plain
elevations while improving the hydrologic connection of the stream to its floodplain.
Objectives
1. Utilize natural channel design principles to create a more stable pattern, profile and
dimension morphology and improve stream habitat using grade/bank stabilization
structures;
2. Lower floodplain berms along Lewis Creek to allow more access by flood events;
3. Successfully plant riparian and flood plain areas with native woody trees and shrubs
conforming to the density requirements specified below;
4. Eliminate accelerated bank erosion, exclude livestock, and reestablish of native
riparian buffers substantially greater than 50 feet in width;
5. Reestablish floodplain connectivity;
6. Preserve the entire Site with a Conservation Easement in perpetuity.
The existing stream reach available for restoration was 1,663 if of Lewis Creek. The stream
restoration consisted of Priority Level 2 restoration along the main channel of Lewis Creek
resulting in 1,7501f of restored stream. The restoration plan also included planting the stream
banks and riparian zones with native tree and shrub species. The designed channel dimension
was based on a combination of dimensionless ratios from the reference reach along Raccoon
Branch, NC Regional Curve for Rural mountain streams, Rosgen stable reach data ranges
( Rosgen 2004a) and existing conditions. Construction was completed in April 2011. Appendix A
includes more details on the Site's location, history and watershed background information.
DATA COLLECTION ASSESSMENT
Five 10 x 10 meter vegetation plots were located, flagged and monitored in the fall of October
2013 by MMI staff using Version 4.2 of the CVS -EEP Level 2 Vegetation Monitoring Protocol
(Lee et al., 2006/8). These five veg. plots will be monitored under contract to the NCEEP for the
next two years by MMI staff. Both planted and volunteer stems were included in MY -03. The
success criteria specified in the mitigation plan requires a minimum survival rate of 320 stems
per acre after MY -03. After MY -04 the success criteria drops to 288 stems /per acre and then in
Lewis Creek 2 Year 3 Monitoring Report
NCEEP Project Number 733 Year 3 of 5
Mogensen Mitigation, Inc. February 2014

MY -05 260 stems per acre are required. Vegetation data was collected by MMI staff in the first
week of October 2013. Based on the overall vegetation count data for MY -03 there are 340
planted stems /acre surviving. There is a combined total of 2,946 planted and volunteer
stems /acre. All plots met the 320 stems /acre threshold, except VP -1 and VP -3 which came in
with 283 stems /acre. The overall low density of surviving planted trees is supplemented with a
good survival of desirable native volunteer species. Salix nigra, alnus serrulata, Betual nigra,
and Cornus amomom were in abundance as natural volunteers. Data collected for all the plots
are included in Appendix C.
Invasive Species
The invasive species encountered included multiflora rose (Rosa multiflora), Japanese
honeysuckle (Lonicera japonica) and ragweed (Ambrosia spp.). Other invasive species observed
included kudzu (Pueraria Montana), Chinese privet (Ligustrum sinense), Chinese lespedeza
(Lespedeza sp.) No invasive species are causing significant problems at this time (other than the
annual ragweed which is out - competing the woody plants). Johnson grass is located along the
path ways and in open areas within the conservation easement and these areas are currently
contracted for ongoing treatment.
Significant Flood Events
MMI began monitoring the Lewis Creek Site in the summer of 2013. At least one significant
flood event has taken place since the data collection began this fall. MMI checked and reset the
existing crest stage gauge (CSG) during the monitoring data collection field work during the first
week of October. The CSG did indicate a ,
bankfull event took place in the spring or summer
of 2013. The CSG stick was photographed and
the data will be included in the appendices. MMI
will include this CSG data in its Annual
Monitoring reports to verify bankfull events have
occurred in that respective year.
Wetland Hydrology
Six (6) Infinitie Continuous -Read Groundwater
gauges were installed according to the Technical Note HY- lA -3.1 (USACE 1993). The gauges
record data every twelve hours and are downloaded quarterly. The six gauges are located within
the flood plain of Lewis Creek and are designed to capture hydrology data for the final wetland
assessment and formal delineation. Each gauge was installed in September /October of 2013 by
MMI. Three gauges (1, 2, 3) are located on the south side of Lewis Creek and three (4, 5, 6) are
located along the north side of Lewis Creek per directions from Mike McDonald (NCEEP PM).
Wetlands typically require groundwater or surface water within 12" of the surface for at least
Lewis Creek 3 Year 3 Monitoring Report
NCEEP Project Number 733 Year 3 of 5
Mogensen Mitigation, Inc. February 2014

12.5% of the growing season (21 consecutive days). Wetland hydrology can be present where the
groundwater is within 12" of the surface for at least 5% of the growing season (11 consecutive
days). According to the NRCS -USDA the growing season runs from March 27 to November 3
which is 221 days. Groundwater hydrology data will be available from the 2014 growing season
in the year 4 monitoring report. MMI will assess the PROJECT wetlands utilizing the Routine Wetland
Determination method (level 2- Onsite Inspection Necessary) as defined in the 1987 USACE Wetland
Delineation Manual. MMI will use this onsite wetland assessment and data collected (specifically, data
the Infinitie groundwater monitoring gauges). MMI will use this data to amend the PROJECT wetland
areas and GIS shape files in the MY 4 Annual Monitoring Report and will also incorporate the findings,
data, and assessment methods utilized during the jurisdictional wetland determination in MY 4 Annual
Monitoring Report.
Stream Assessment
Monitoring results from this year's monitoring field work indicate that the stream banks and the
present stream dimensions along the restored reach appear to be stable. The Site has experienced
post - construction bankfull events (see CSG Data). The entire 1,7501f reach of Lewis Creek was
surveyed and assessed from the project origin at North Ridge Road Bridge to the project
terminus. This assessment included a long -pro survey, five surveyed cross - sections, visual
stability and field verifying the Current Condition Plan View (Appendix B). The cross - section
survey's indicates a median bankfull width of 23.3 feet which does not indicate a significant
change for the baseline data bankfull width listed at 23.81 feet.
One center bar was located in the first third of the restoration reach and is beginning to force the
stream to migrate laterally. Although this does not require repair work at this time the center bar
area should be closely watched in the future monitoring
years. MY -01 report indicated a prevalence of in- stream
vegetation in the channel but MMI did not identify this as a
problem issue. The stream flows seem to be adequate to keep
in- stream vegetation from overtaking the stream channel. The
sediment and substrate loads were a mix of sand in slower
moving stream reaches and cobble & gravel in the riffles.
Moderate particle size coarsening is prevalent in the d40 -d50
range while fining appears to be prevalent above that
threshold. Based on the recent monitoring data and our visual inspection the channel appears to
be functioning as designed and maintaining stability. Stream bank erosion was not observed
anywhere along the restored reach. There was a substantial amount of sand being deposited on
the flood plain leading to failure of some of the planted material. All structures including log and
rock vanes and J -hook log vanes appear to be functioning as designed not showing any signs of
erosion or piping.

4 Year 3 Monitoring Report
Year 3of5
February 2014

Cross - section survey data indicates that during MY -03 the channel geometry is stable with only
slight changes in channel morphology evident.
Problem Areas
The following is a summary of other problem areas (other than vegetation survival and invasive
species) such as beaver encroachment and anthropomorphic impacts. No beaver activity was
observed during the numerous site visits made this fall. There is some passive recreation by
pedestrians but this is limited to walking on the mowed paths so no significant problems exist at
this time.
Annual Monitoring Summary
Based on the data collected in MY -03 and the visual site assessments, the Lewis Creek project is
trending toward a successful restoration project. The main problems are with planted tree and
shrub survival in the flood plain areas that are undergoing active sand deposition. These areas
tend to support annual herbaceous vegetation that can root quickly in the new sand piles. Annual
mean calculations for vegetation CVS data show 340 stems /acre of planted trees at the site. On
average the project as a whole met success criteria with two out of five vegetation plots not
meeting the minimum threshold.
The pattern, profile and dimension of the restored channel appear to be maintaining the stream
bank vertical and horizontal integrity that was envisioned in the design. No bank failures were
observed and no erosion, only deposition was noted. The stream riffles are moving cobble and
gravel along with a great deal of sand. There is one center bar that deserves attention during MY-
04.
Some of the baseline information provided in this report was derived from the mitigation plan
and MY -01 report by JJG. Detailed narrative background descriptions and supporting
information can be found in the Baseline Monitoring Document and As -Built Report (April
2012) and in the Restoration Plan (December 2007). All documents are available on EEP's
website. All the raw data for the supporting tables and graphs in the appendices is available upon
request.
11. Methodology
Monitoring methodologies follow the CVS -EEP Level 2 Vegetation Monitoring Protocol for
Recording Vegetation (Lee et al 2008). All photos were taken with a Nikon digital camera and

are available electronically. A Trimble Hand Held GPS unit was used to locate veg. plot corners,
groundwater gauges and problem areas.
An HP 48G+ calculator was used to download the six Infinity groundwater gauges. All graphics
have been done using ArcGIS and are available electronically.
1.) Vegetation Methodologies
Five 10 x 10 square meter veg. plots were installed and monitored according to the CVS-
EEP Level 2 Vegetation Monitoring Protocol Version 4.2 (Lee et al 2006/8). The plot
corners are marked with 1" Aluminum or PVC pipe and flagged with bright red flagging
tape. Data collected from each plot is included in Appendix C. Monitoring plot locations
are shown on the maps in Appendix B. Plant identification was aided by the seminal
publication Flora of the Carolinas, Virginia, Georgia and Surrounding Areas (Schaffle
& Weakly).
2.) Wetland Methodologies
Six (6) Infinity groundwater Monitoring Gauges were installed on September 26, 2013
and all data since installation was collected on February 1, 2014. Monitoring well #1
malfunctioned and was replaced on October 28, 2013. This data is presented in Appendix
E and is plotted with daily precipitation data and daily USGS stream stage data. All
gauges will be downloaded quarterly throughout the growing season to ensure that the
gauges are functioning properly. Data is provided in an Excel spreadsheet and may be
supplemented with data from the NC CRONOS database, Station ID NC- HN -15.
3.) Stream Methodologies
Five cross - sections and 1,750 linear feet of stream long -pro were surveyed in October
2013 using a Trimble RDK survey -grade GPS unit. The survey data locations were
plotted using ARC GIS 10.0. Cross - sectional data was based on a linear alignment
between end points marked by metal pins. Measurements at each cross - section include
points at point of origin, bankfull, top of bank, toe of slope and thalweg for each stream
side supplemented with photo's. Long -pro measurements include thalweg, and water
surface taken at the head of feature (i.e. riffle, run, pool glide) in addition to pool depths.
In addition, visual and photographic assessment of in- stream structures was conducted to
determine overall project success. Structure failures include collapse of structure,
undermining, abandonment of channel, piping around the structure. Stream assessment
data are included in Appendix D with cross - sections and monitored stream reaches
indicated on maps in Appendix B.
All raw data supporting the tables, figures and graphs in the appendices are available to NCEEP
upon request.
